 50

 (i) ICF shall prepare or cause to be prepared and file or cause to be filed, on a basis reasonably consistent with past practice, any Tax Returns of
Synergy and the Acquired Subsidiaries for Tax periods that begin before the Effective Date and end after the Effective Date (“Straddle Periods”). ICF shall permit the Shareholders’ Representative to review and comment on each
such Tax Return described in the preceding sentence prior to filing, and ICF shall make all changes reasonably requested by Synergy in good faith (unless ICF is advised in writing by its independent outside accountants or attorneys that such changes
(i) are contrary to applicable Law, or (ii) will, or are likely to have a material adverse effect on ICF or any of its Affiliates). Within fifteen (15) days after the date on which ICF pays any Taxes of Synergy and the Acquired
Subsidiaries with respect to any Straddle Period, the Shareholders shall, to the extent such Taxes have not been accrued or otherwise reserved for on the Closing Financial Statements, pay to ICF the amount of such Taxes that relates to the portion

 (2) In the case of any Taxes (other than gross receipts Taxes) that are payable with respect to a Straddle Period, the portion of such Taxes allocable
to the portion of the Straddle Period prior to the Effective Date shall be equal to the product of all such Taxes multiplied by a fraction the numerator of which is the number of days in the Straddle Period from the commencement of the Straddle
Period through and including the Effective Date and the denominator of which is the number of days in the entire Straddle Period; provided, however, that appropriate adjustments shall be made to reflect specific events that can be
identified and specifically allocated as occurring on or prior to the Effective Date (in which case the Shareholders shall be responsible for any Taxes related thereto) or occurring after the Effective Date (in which case, ICF shall be responsible
for any Taxes related thereto). 
 (c) Cooperation on Tax Matters. 
 (i) ICF and the Shareholders shall cooperate fully, as and to the extent reasonably requested by any party, in connection with the filing of Tax Returns
pursuant to this Section and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information reasonably relevant to any
such audit, litigation or other proceeding and making their respective employees, outside consultants and advisors available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. ICF and
the Shareholders agree (A) to retain all books and records with respect to Tax matters pertinent to 
  

 51 

 Synergy and the Acquired Subsidiaries relating to any taxable period beginning before the Effective Date until the
expiration of the statute of limitations (and, to the extent notified by ICF or the Shareholders’ Representative, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any
taxing authority, and (B) to give the other reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other so requests, ICF or the Shareholders, as the case may be, shall allow the other
to take possession of such books and records. 
 (ii) ICF and the Shareholders further agree, upon request, to use their best efforts to
obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions

either party may be required to report pursuant to Section 6043 of the Code and all Treasury Department Regulations promulgated thereunder.

similar tax imposed by any governmental authority) shall be shared equally between ICF and the Shareholders and each party shall be responsible for one-half of such Taxes. The party required by Law to do so will file all necessary Tax Returns and
other documentation with respect to all such transfer, documentary, sales, use, stamp, registration and other Taxes and fees, and, if required by applicable Law, the other parties will join in the execution of any such Tax Returns and other
documentation. 
 5.8 Public Announcements.

 5.10 Columbia Road Lease. 
 (a) The Shareholders acknowledge that, following the completion of the Closing, Synergy’s existing headquarters located at 1763 Columbia Road, N.W.,
Washington D.C. (the “Columbia Road Premises”) shall be excess to ICF’s and Synergy’s space needs. ICF and the Shareholders further acknowledge and agree that ICF’s willingness to enter into this Agreement was
conditioned in part on the requirements that (i) Synergy’s business operations and its employees be relocated, from the Columbia Road Premises to one of ICF’s locations in the Washington, D.C. metropolitan area (primarily in Fairfax,
Virginia); (ii) the relocation would take place if at all possible within thirty (30) days of the Closing (or if not possible then as soon thereafter as possible); and (iii) the Shareholders establish and fund the Lease Escrow for the

Lease Escrow the Principal Shareholders jointly and severally indemnify and hold harmless, ICF and Synergy from any and all liability of any kind or nature whatsoever under the Columbia Road Lease.

Lease or that are otherwise related in any way to Synergy’s continued leasehold of the Columbia Road Premises (collectively the “Leasehold Costs”) shall be payable from the Lease Escrow with no further action by the
Shareholders or the Shareholders’ Representative. 
 (c) In addition to the Lease Escrow, the Principal Shareholders hereby agree to
indemnify and hold any ICF Indemnitees harmless from and against (i) any and all Leasehold Costs and (ii) all other claims arising under or with respect to the Columbia Road Lease and/or Synergy’s continued leasehold of the Columbia
Road Premises (collectively, the “Leasehold Obligations”). The Principal Shareholders’ indemnification of the Leasehold Obligations shall be governed by the provisions of Article VIII, it being understood that any
indemnification for Leasehold Costs shall be treated as a Direct Claim and that all other indemnifications of Leasehold Obligations shall be treated as Third-Party Claims or Direct Claims depending on their nature; provided, however, that in no
event shall the limitations contained in Sections 8.2(e) and (f) apply to any Leasehold Obligation Claim. To the extent that any ICF Indemnitees prevail in a claim for or with respect to Leasehold Obligations (a “Leasehold
Indemnification Claim”), then the Leasehold Indemnification Claim shall be satisfied from the Lease Escrow (and the Escrow Agent shall pay to ICF from the Lease Escrow the amount of the Leasehold Indemnification Claim) with no further
action required by the Shareholders or the Shareholders’ Representative. In the event that a Leasehold Indemnification Claim is in excess of the Lease Escrow, the Principal Shareholders shall be and remain jointly and severally liable for any
or all of the Leasehold Indemnification Claim. 
 (d) Within thirty (30) days following the earlier of (i) the expiration of the
term of the Columbia Road Lease and the written acknowledgement by the landlord that Synergy has no further liability under the Columbia Road Lease, or (ii) the full, complete and 
  

 53 

 unconditional release (in form reasonably satisfactory to ICF) of Synergy from any and all liabilities under the Columbia
Road Lease signed by the landlord and all other required Persons, ICF and the Shareholders’ Representative shall instruct the Escrow Agent pursuant to the Lease Escrow Agreement to cause any amounts remaining in the Lease Escrow (less any

documents with the applicable Governmental Authorities (the “Post-Closing Pension Plan Administration”) and (ii) all costs associated with the Post-Closing Pension Plan Administration (collectively the “Post-Closing
Pension Plan Administrative Costs”), subject to 5.11(c). The Shareholders and Synergy, ICF and ICF Holdings shall cooperate fully, as and to the extent reasonably requested by any party, in connection with the Post-Closing Pension Plan
Administration pursuant to this Section. 
 (b) Colvin, Pickard, Zimmerman and Monika Ruppert (collectively the “Pension Plan
Fiduciaries”) are, or were, trustees under certain Pension Plans and are entitled to indemnification by Synergy under the documents evidencing such Pension Plans. Subject to Section 5.11(c), ICF agrees to indemnify, or cause Synergy to
indemnify, any or all of the Pension Plan Fiduciaries for claims with respect to such Pension Plans (collectively “Pension Plan Claims”) made after the Closing Date and prior to the expiration of any applicable statutes of

assigns), together with their respective officers, directors, employees, stockholders, agents and affiliates, officers, directors, agents or representatives, from any Pension Plan Claims that in the aggregate exceed $250,000. The Shareholders (to
the extent of the General Indemnity Escrow) and Principal Shareholders shall jointly and severally be responsible for and shall indemnify and hold harmless ICF, Synergy and the Acquired Subsidiaries for all Pension Plan Claims that in the aggregate
exceed the ICF Pension Plan Claims / Costs Cap. 
 (d) Claims with respect to Section 5.11(b) and (c) shall be treated as Direct
Claims pursuant to Section 8.2(d), but shall not be subject to the limitations of Sections 8.2(f)  
  

 54 

 and (g). To the extent that that ICF, Synergy or an Acquired Subsidiary prevails in a Claim with respect to a Pension
Plan Claim under Section 5.11(c), that Claim shall be satisfied (i) first by Synergy, ICF and/or ICF Holdings up to balance of the ICF Pension Plan Claims / Costs Cap, (ii) second from the General Indemnity Escrow, to the extent of
the then remaining balance of the General Indemnity Escrow, and (iii) third, to the extent that the Claim is in excess of the then remaining balance in the General Indemnity Escrow, then by and from the Principal Shareholders jointly and
severally; provided, however that the Shareholders’ maximum aggregate liability under this Section 5.11(d) shall not exceed Six Million Dollars ($6,000,000) (with the Non-Principal Shareholders aggregate liability limited to the extent of
the General Indemnity Escrow).

 Except for the Surviving Representations, the representations and warranties of the Shareholders, on the one hand, and ICF, on the other hand, in this
Agreement or in any certificate or document delivered on or before the Closing Date shall survive the Closing and shall remain effective until eighteen (18) months following the Closing (the “Survival Date”). After the
expiration of such period, such representations and warranties and the provisions of this ARTICLE VIII shall expire and be of no further force and effect except to the extent that a claim or claims shall have been asserted by ICF or the
Shareholders, as the case may be, with respect thereto on or before the expiration of such period, provided however that the following representations and warranties (collectively the “Surviving Representations” shall survive
the Survival Date until the date specified below. 
 (i) Claims for indemnification based on breaches of representations and warranties of
the Shareholders in Section 3.11 (Title to Shares) shall survive the Survival Date and claims for indemnification based on breaches of such representations and warranties may be made at any time following the Closing. 
  

 58 

 (ii) Claims for indemnification based on breaches of representations and warranties of the Shareholders
in Sections 3.21 (Compliance with Laws), 3.22 (Environmental Matters), and 3.29 (Tax Matters) shall survive the Survival Date and claims for indemnification based on breaches of such representations and warranties may be made up to the date of the
applicable statute of limitations. 
 (iii) Claims for indemnification based on breaches of representations and warranties of the
Shareholders in Sections 3.18(c)(xi) and (xii) and 3.18(f) (Federal and State Government Contracts) shall survive the Survival Date and claims for indemnification based on breaches of such representations and warranties may be made up to the
date thirty (30) days after the DCAA audits (or similar federal audits) have been completed for each of 2003 and 2004. 
 (iv) Claims
for indemnification based on breaches of representations and warranties of the Shareholders in Section 3.28 (ERISA) shall survive the Survival Date and claims for indemnification based on breaches of such representations and warranties may be
made up to the fourth (4th) anniversary of the Effective Date, 
 The undersigned acknowledge and agree that the covenants contained in this Agreement, including, but not limited to the covenants contained in ARTICLE V above shall
survive Closing and are unaffected by this Section 8.1. 
 8.2 Indemnification. 
 (a) By ICF. 
 (i) Subject to
Section 8.2(f), ICF shall protect, defend, indemnify and hold harmless the Shareholders and their agents, representatives, successors and assigns (“Shareholders Indemnitees”) from and against any losses, damages and expenses
(including, without limitation, except as provided in Section 8.2(d), reasonable counsel fees, costs and expenses incurred in investigating and defending against the assertion of such liabilities) that may be sustained, suffered or incurred by
the Shareholders or their Affiliates, and that are related to (A) any breach by ICF of its representations and warranties, (B) any breach by ICF of its covenants in this Agreement, (C) Taxes as provided in paragraph (ii) of this
Section 8.2(a) or (D) any liabilities of Synergy or the Acquired Subsidiaries following the Closing other than those liabilities for which the Shareholders have agreed to indemnify ICF pursuant to Section 8.2(b) of this Agreement.

 (ii) The obligations of ICF under paragraph (i) of this Section 8.2(a) shall extend to (A) all Taxes with respect to
taxable periods beginning after the Effective Date (including any Taxes with respect to transactions properly treated as occurring on the day after the Effective Date pursuant to Treasury Regulations Section 1.1502-76(b)(1)(ii)(B) or any
similar provision of state, local or foreign law) and (B) all Taxes (other than federal income Taxes) with respect to Straddle Periods to the extent that such Taxes are allocable to the period after Effective Date pursuant to
Section 5.7(b)(ii). 
  

 59 

 (b) By the Shareholders. 
 (i) Subject to Sections 8.2(e) and 8.2(g), the Shareholders jointly and severally to the extent of the General Indemnity Escrow and the Principal
Shareholders jointly and severally to any extent in excess of the General Indemnity Escrow shall protect, defend, indemnify and hold harmless ICF, Synergy, the Acquired Subsidiaries and their respective Affiliates, and their officers, directors,
employees, agents, representatives, successors and assigns (“ICF Indemnitees”) from and against any losses, damages and expenses (including, without limitation, except as provided in Section 8.2(c), reasonable counsel fees,
costs and expenses incurred in investigating and defending against the assertion of such liabilities) that may be sustained, suffered or incurred by ICF Indemnitees and that are related to (A) any breach by the Shareholders of their
representations and warranties in this Agreement, (B) any breach by the Shareholders of their covenants in this Agreement, (C) Taxes as provided in paragraph (ii) of this Section 8.2(b), (D) the Accrued Principal
Shareholders’ Bonuses, and Synergy Pre-2004 Bonuses, (E) the Shareholders’ Transaction Costs (unless paid by ICF pursuant to Section 5.4), (F) the Leasehold Obligations and (G) Indebtedness for Borrowed Money not
disclosed on the Financial Statements and in excess of what is permitted under Section 3.34. 
 (ii) The obligations of the
Shareholders under paragraph (i) of this Section 8.2(b) shall extend to (A) all Taxes with respect to taxable periods ending on or prior to the Effective Date and (B) all Taxes (other than federal income Taxes) with respect to
Straddle Periods to the extent that such Taxes are allocable to the portion thereof prior to pursuant to Section 5.7(b), and in all events, only to the extent such Taxes have not been accrued or otherwise reserved for on the Closing Financial
Statements (it being the intent of the parties that all of the provisions of this Agreement shall be interpreted to avoid requiring the Shareholders to pay (or receive a reduction in purchase price) twice for the same Tax). Such obligations shall be
without regard to whether there was any breach of any representation or warranty under ARTICLE III with respect to such Tax or any disclosures that may have been made with respect to ARTICLE III or otherwise. The indemnification obligations under
this paragraph (ii) shall apply even if the additional Tax liability results from the filing of a return or amended return with respect to a pre-Effective Date transaction or period (or portion of a period) by ICF. ICF shall not cause or permit
Synergy or any Acquired Subsidiary to file an amended Tax Return with respect to any taxable period ending on or prior to the Effective Date or any Straddle Period unless (y) the Shareholders’ Representative consents in its reasonable
discretion, or (z) ICF obtains a written opinion from its outside tax consultant(s) that such an amendment is legally required. In the event of any conflict between the provisions of this Section 8.2(c)(ii) and any other provision of this
Agreement, the provisions of this Section shall control. 
 (c) Procedure for Third-Party Claims. 
 (i) If any Third-Party Claims shall be commenced, or any claim or demand shall be asserted (other than audits or contests with Taxing Authorities
relating to Taxes), in respect of which the Indemnified Party proposes to demand indemnification by the Indemnifying Party under Sections 8.2(a) or 8.2(b), the Indemnified Party shall notify the Indemnifying Party in writing of such demand and the
Indemnifying Party shall have the right to assume the entire control of the defense, compromise or settlement thereof (including the selection of counsel), subject to the right of the Indemnified Party to participate (with counsel of 
  

 60 

 its choice), but the fees and expenses of such additional counsel shall be at the expense of the Indemnified Party. The
Indemnifying Party will not compromise or settle any such action, suit, proceeding, claim or demand (other than, after consultation with Indemnified Party, an action, suit, proceeding, claim or demand to be settled by the payment of money damages
and/or the granting of releases, provided that no such settlement or release shall acknowledge the Indemnified Party’s liability for future acts or obligate ICF with respect to activities of Synergy) without the prior written consent of
the Indemnified Party, which consent shall not be unreasonably withheld. 
 (ii) Notwithstanding anything to the contrary contained in this
Section 8.2(c), ICF shall have the sole right to control and make all decisions regarding interests in any Tax audit or administrative or court proceeding relating to Taxes, including selection of counsel and selection of a forum for such
contest, provided, however, that in the event such audit or proceeding relates to Taxes for which Shareholders are or may be responsible to indemnify ICF, (A) ICF, Synergy and the Shareholders shall cooperate in the conduct of any audit or
proceeding relating to such period, (B) the Shareholders, acting through the Shareholders’ Representative, shall have the right (but not the obligation) to participate in such audit or proceeding at Shareholders’ expense, (C) ICF
shall not enter into any agreement with the relevant Taxing Authority pertaining to such Taxes without the written consent of the Shareholders’ Representative, which consent shall not unreasonably be withheld, and (D) ICF may, without the
written consent of Shareholders, enter into such an agreement provided that ICF shall have agreed in writing to accept responsibility and liability for the payment of such Taxes and to forego any indemnification under this Agreement with respect to
such Taxes. 
 (iii) The parties will keep each other informed as to matters related to any audit or judicial or administrative proceedings
involving Taxes for which indemnification may be sought hereunder, including, without limitation, any settlement negotiations. Refunds of Tax relating to periods ending prior to the Effective Date (or to that portion of a Split Period that is prior
to Effective Date under the principles of Section 8.2(a)(ii) shall be the property of the Shareholders, but only to the extent that such refunds are not attributable to (A) net operating loss or other carrybacks from periods ending after
the Effective Date, or (B) refund claims that are initiated by ICF (provided that ICF gives the Shareholders’ Representative prior notice of such possible claim and the Shareholders decline to pursue such refund at their own
expense); provided, however, that ICF shall in no event have an obligation to file or cause to be filed a claim for refund with respect to any Taxes relating to any period. 
 (iv) Any indemnity payment or payment of Tax by the Shareholders to ICF or its Affiliates as a result of any audit or contest shall be reduced by the
present value of the correlative amount by which any Tax of ICF (including Synergy and the Acquired Subsidiaries after the Effective Date) or its Affiliates is or will be reduced for periods ending after the Effective Date as a result thereof.
Except as otherwise provided herein, all other refunds of Tax are the property of ICF. 
 (v) The Indemnified Party shall cooperate fully in
all respects with the Indemnifying Party in any defense, compromise or settlement, subject to this Section 8.2(c) including, without limitation, by making available all pertinent books, records and other information and personnel under its
control to the Indemnifying Party. 
  

 61 

 (d) Procedure for Direct Claims. 
 (i) Any Direct Claim shall be asserted by written notice given by the Indemnified Party to the Indemnifying Party (each a “Direct Claim
Notice”). Each Direct Claim Notice shall set forth with reasonable specificity the basis of the claim for indemnification. The Indemnifying Party shall have a period of twenty (20) Business Days from the date of receipt (the
“Direct Claim Notice Period”) within which to respond to a Direct Claim Notice. If the Indemnifying Party does not respond in writing within the Direct Claim Notice Period, then the Indemnifying Party shall be deemed to have
accepted responsibility for the claimed indemnification and shall have no further right to contest the validity of that claim. If the Indemnifying Party does respond in writing within the Direct Claim Notice Period, and rejects the claim in whole or
in part, the Indemnified Party shall be free to pursue all remedies under Section 9.11. To the extent that any ICF Indemnitees prevail in a Direct Claim (or the Shareholders concede, or otherwise do not timely respond to a Direct Claim Notice
made by ICF) then the Direct Claim shall be satisfied from the General Indemnity Escrow (and the Escrow Agent shall pay to ICF from the General Indemnity Escrow the amount of the Direct Claim) with no further action required by the Shareholders or
the Shareholders’ Representative. Notwithstanding the foregoing, in the event that a Direct Claim is in excess of the General Indemnity Escrow, the Shareholders shall be and remain jointly and severally liable for any or all of the Direct Claim
(but ICF shall in no event have recourse to the Leasehold Escrow in respect of the Direct Claim except to the extent a Direct Claim relates to Leasehold Obligations). 
 (ii) Costs Related to Direct Claims. Notwithstanding anything in this Section 8.2 to the contrary, except as otherwise may be ordered by a court of competent jurisdiction, Principal Shareholder Indemnitees
and ICF Indemnitees shall bear their own costs, including counsel fees and expenses, incurred in connection with Direct Claims against ICF and the Shareholders, respectively, hereunder that are not based upon claims asserted by third parties.

 (e) Calculation of Amount of Claims and Losses. The amount of any claims or losses subject to indemnification under
Section 8.2(b) shall be calculated net of any amounts that are recovered by ICF or its Affiliates (including Synergy after the Closing) under applicable insurance policies held by ICF or its Affiliates, and ICF agrees to make or cause to be
made all reasonable claims for insurance under such policies that may be applicable to the matter giving rise to the indemnification claim hereunder. The amount of any claims or losses subject to indemnification under Section 8.2(b) shall be
calculated net of the present value of any Tax benefits to ICF or its Affiliates (including Synergy and the Acquired Subsidiaries after the Closing) resulting from the matter giving rise to the indemnification claim hereunder. Notwithstanding
anything to the contrary, the limitations in this Section 8.2(e) shall not apply to Leasehold Indemnification Claims. 
 (f)
Limitations on Rights of ICF Indemnitees. The rights of ICF Indemnitees to indemnification by the Shareholders for breaches of representations and warranties hereunder shall be subject to the limitations that ICF Indemnitees shall not be
entitled to indemnification with respect to a claim or claims of breach of representation and warranty by the Shareholders unless any such claim has a value in excess of Five Thousand Dollars ($5,000) and the aggregate amount of all such claims in
excess of $5,000 exceeds $50,000, in which event the indemnity provided for in this Section 8.2 shall be effective with respect to the total amount of such 
  

 62 

 damages (including the first $50,000); provided, however, that the Shareholders’ maximum liability to ICF
Indemnitees under this Section 8.2 shall not exceed Three Million Two Hundred Ninety Eight Thousand Seven Hundred Fifty Dollars ($3,298,750) (the “General Indemnity Cap”). The aforementioned limitations shall not apply to the
indemnification liabilities of the Shareholders pursuant to Section 3.11 (Title), Section 3.28 (ERISA), Section 3.29 (Taxes), Section 8.2(b)(i)(B), (C) and (D), Section 8.2(b)(ii), claims based upon a breach of
Section 5.5 and, or for claims based on fraud, intentional misrepresentation or criminal acts on the part of the Shareholders. Notwithstanding anything to the contrary contained herein, the limitations in this Section 8.2(f) shall not
apply to claims under Section 5.11, or Leasehold Indemnification Claims and such claims shall not in any way count against the General Indemnity Cap. Notwithstanding anything to the contrary continued herein, ICF agrees that the liability of
the Shareholders other than the Principal Shareholders (the “Non-Principal Shareholders”) shall have to ICF with respect to indemnification obligations under this Agreement shall be limited to each Non-Principal Shareholders’
Purchase Consideration Percentage of the then remaining balance in the General Indemnity Escrow or the Lease Escrow, as applicable. 
 (g)
Limitations on Rights of Shareholder Indemnitees. The rights of the Shareholder Indemnitees to indemnification by ICF for breaches of representations and warranties hereunder shall be subject to the limitation that the Shareholder Indemnitees
shall not be entitled to indemnification with respect to a claim or claims for a breach of a representation and warranty by ICF unless the aggregate of damages with respect to all such claims exceeds $50,000, in which event the indemnity provided
for in this Section 8.2 shall be effective with respect to the total amount of such damages (including the first $50,000); provided, however, that ICF’s maximum liability to the Shareholder Indemnitees under this Section 8.2
shall not exceed Five Hundred Thousand Dollars ($500,000). The aforementioned limitations shall not apply to the indemnification liabilities of Synergy, ICF and ICF Holdings with respect to claims under Section 5.11 or claims based on fraud,
intentional misrepresentation or criminal acts on the part of ICF. 
 (h) Limitation on Rights of Shareholders. The Shareholders
acknowledge and agree that they shall have no right to make a claim against Synergy pursuant to any indemnity provision or agreement or otherwise in respect of claims of ICF Indemnitees made pursuant to Section 8.2(b). 
 8.3 Escrow Accounts. 
 Pursuant to
Section 2.1 and the Escrow Agreements, at the Closing, ICF shall deliver to the Escrow Agent the Escrow Deposit and the Escrow Agent shall set up two separate escrows: the Lease Escrow under the Lease Escrow Agreement and the General Indemnity
Escrow under the General Indemnity Escrow Agreement to secure the Shareholders’ indemnification obligations under Section 5.10 and Article VIII. 
 (a) Except for Leasehold Indemnification Claims, the Shareholders’ Representative and ICF shall cause the Escrow Agent pursuant to the terms of the General Indemnity Escrow Agreement to cause any amounts deemed
to be due ICF Indemnitees from the Shareholders pursuant to Section 8.2(c), 8.2(d), or Section 9.11 to be paid from the General Indemnity Escrow. 
  

 63 

 (b) Within thirty (30) days following the expiration of the Survival Date, the Escrow Agent will
cause any amounts remaining in the General Indemnity Escrow (less any amount which has been or shall be offset or is subject to a pending dispute) to be delivered to the Shareholders’ Representative to be distributed by the Shareholders’
Representative to the Shareholders as Post-Closing Purchase Consideration. The expiration of the Lease Escrow and the distribution of any remaining balance of the Lease Escrow shall be governed by Section 5.10. 
 8.4 Exclusive Remedies. 
 The remedies
provided for in this Agreement shall be the sole and exclusive remedies of the parties and their respective officers, directors, employees, affiliates, agents, representatives, successors and assigns for any breach of or inaccuracy in any
representation, warranty or covenant contained in this Agreement or any certificate delivered at Closing; provided, however, that nothing herein is intended to waive any claims for fraud or waive any equitable remedies to which a party may be
entitled. 
 8.5 Mitigation. 
 Each party agrees to use reasonable efforts to mitigate any loss, liability or damage that forms the basis of a claim hereunder. 
 ARTICLE IX 
 Miscellaneous 
 9.1 Further Assurances. 
 At any time and from time to time after the Closing Date, the Shareholders,
the Shareholders’ Representative, Synergy and/or any or all of the Acquired Subsidiaries will, upon the request of ICF, and ICF will, upon the request of the Shareholders or the Shareholders’ Representative perform, execute, acknowledge
and deliver all such further acts, deeds, assignments, transfers, conveyances, powers of attorney and assurances as may be reasonably required by any of them, to effect or evidence the Contemplated Transactions.

9.3 Governing Law. 
 This Agreement
shall in all respects be governed by, and construed in accordance with, the laws (excluding conflict of laws rules and principles) of the Commonwealth of Virginia applicable to agreements made and to be performed entirely within the Commonwealth of
Virginia, including all matters of construction, validity and performance. 
 9.4 Entire Agreement. 
 This Agreement, together with the Exhibits and Schedules hereto and the other Transaction Documents, constitutes the entire agreement of the parties
relating to the subject matter hereof and supersedes all prior contracts or agreements, whether oral or written. There are no representations, agreements, arrangements or understandings, oral or written, between or among the parties relating to the
subject matter of this Agreement that are not fully expressed in this Agreement. 
 9.5 Severability. 
 Should any provision of this Agreement or the application thereof to any Person or circumstance be held invalid or unenforceable to any extent:
(a) such provision shall be ineffective to the extent, and only to the extent, of such unenforceability or prohibition and shall be enforced to the greatest extent permitted by Law; (b) such unenforceability or prohibition in any
jurisdiction shall not invalidate or render unenforceable such provision as applied (i) to other Persons or circumstances or (ii) in any other jurisdiction; and (c) such unenforceability or prohibition shall not affect or invalidate

 9.6 Amendment. 
 Neither this Agreement nor any of the terms hereof may be terminated, amended, supplemented or modified orally, but only by an instrument in writing signed by the party against which the enforcement of the

 9.7 Effect of Waiver or Consent. 
 No waiver or consent, express or implied, by any Person to or of any breach or default by any party in the performance by such party of its obligations

or any abandonment or discontinuance of steps to 
  

 66 

 enforce any right or power, shall preclude any other or further exercise thereof or the exercise of any other right or
power. Failure on the part of a party to complain of any act of any party or to declare any party in default, irrespective of how long such failure continues, shall not constitute a waiver by such Person of its rights hereunder until the applicable

right to use any or all other remedies. Such rights and remedies are given in addition to any other rights the parties may have under applicable Law or otherwise. 
 9.9 Parties in Interest; Limitation on Rights of Others. 
 The terms of this Agreement shall be
binding upon, and inure to the benefit of, the parties hereto and their respective legal representatives, successors and assigns. Nothing in this Agreement, whether express or implied, shall be construed to give any Person (other than the parties
hereto and their respective legal representatives, successors and assigns and as expressly provided herein) any legal or equitable right, remedy or claim under or in respect of this Agreement or any covenants, conditions or provisions contained
herein, as a third party beneficiary or otherwise. 
 9.10 Assignability. 
 This Agreement shall not be assigned by any party hereto without the prior written consent of the other party hereto, provided, however, that (a) the
prior written consent of the Shareholders’ Representative shall not be unreasonably withheld, delayed or conditioned with respect to any assignment by ICF of its rights and obligations under this Agreement to an Affiliate of ICF so long as such
assignment does not relieve ICF of its obligations hereunder; and (b) the prior written consent of the Shareholders’ Representative shall not be required for any collateral assignment of ICF’s rights and remedies under this Agreement
to any lender under credit and collateral agreements, as such agreements may be amended, modified or replaced from time to time, so long as such lender does not have the right to exercise any of ICF’s rights and remedies under this Agreement in
the absence a default by ICF under the applicable credit and collateral documents. The Shareholders hereby agree to execute and deliver (and authorize the Shareholders’ Representative to execute and deliver) such documents, instruments and
agreements as such lender may reasonably require to confirm, reaffirm or perfect such collateral assignment. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted
assigns. 
 9.11 Dispute Resolution and Arbitration. 
 In the event that any dispute arises between the parties pertaining to the subject matter of this Agreement, and the parties, through the senior management of ICF and the Shareholders’ Representative, are unable
to resolve such dispute within a reasonable time through negotiations and mediation efforts, such dispute shall be resolved as set forth in this Section 9.11. 
  

 67 

 (a) The procedures of this Section 9.11 may be initiated by a written notice (“Dispute
Notice”) given by one party (“Claimant”) to the other, but not before thirty (30) days have passed during which the parties have been unable to reach a resolution as described (unless any party would be materially
prejudiced by such delay). The Dispute Notice shall be accompanied by (i) a statement of the Claimant describing the dispute in reasonable detail and (ii) documentation, if any, supporting the Claimant’s position on the dispute.
Within twenty (20) days after the other party’s (“Respondent”) receipt of the Dispute Notice and accompanying materials, the parties shall submit the dispute to mediation in the Washington, D.C. area under the rules of the
American Arbitration Association. All negotiations and mediation procedures pursuant to this paragraph (a) shall be confidential and treated as compromise and settlement negotiations and shall not be admissible in any arbitration or other
proceeding. 
 (b) If the dispute is not resolved as provided in paragraph (a) within sixty (60) days after the Respondent’s
receipt of the Dispute Notice, the dispute shall be resolved by binding arbitration. Within the sixty-day period referred to in the immediately preceding sentence, the parties shall agree on a single arbitrator to resolve the dispute. If the parties
fail to agree on the designation of an arbitrator within said sixty-day period, the American Arbitration Association in the Washington, D.C. area shall be requested to designate the single arbitrator. If the arbitrator becomes disabled, resigns or
is otherwise unable to discharge the arbitrator’s duties, the arbitrator’s successor shall be appointed in the same manner as the arbitrator was appointed unless the parties originally agreed on the arbitrator who becomes unable to
discharge his duties and they can not agree on a successor within thirty (30) days in which case, the American Arbitration Association in the Washington, D.C. area shall be requested to designate a successor arbitrator. 
 (c) Except as otherwise provided in this Section 9.11, the arbitration shall be conducted in accordance with the Commercial Rules of the American
Arbitration Association, which shall be governed by the United States Arbitration Act. 
 (d) Any resolution reached through mediation and
any award arising out of arbitration (i) shall be binding and conclusive upon the parties; (ii) shall be limited to a holding for or against a party, and affording such monetary remedy as is deemed equitable, just and within the scope of
this Agreement; (iii) may not include special, incidental, consequential or punitive damages; (iv) may in appropriate circumstances include injunctive relief; and (v) may be entered in court in accordance with the United States
Arbitration Act. 
 (e) The arbitrator may not limit, expand or otherwise modify the terms of this Agreement. 
 (f) The laws of the Commonwealth of Virginia shall apply to any mediation, arbitration, or litigation arising under this Agreement. 
 (g) Each party shall bear its own expenses incurred in any mediation, arbitration or litigation, but any expenses related to the compensation and the
costs of any mediator or arbitrator shall be borne equally by the parties to the dispute. 
  

 68 

 (h) A request by a party to a court for interim measures necessary to preserve a party’s rights and
remedies for resolution pursuant to this Section 9.11 shall not be deemed a waiver of the obligation to mediate or of the agreement to arbitrate. 
 (i) The parties, their representatives, other participants and the mediator or arbitrator shall hold the existence, content and result of mediation or arbitration in confidence. 
 9.12 Jurisdiction; Court Proceedings; Waiver of Jury Trial. 
 Subject to the provisions of Section 9.11, any suit, action or proceeding against any party to this Agreement arising out of or relating to this Agreement shall be brought in any Federal or state court located in
the Commonwealth of Virginia and each of the parties hereby submits to the exclusive jurisdiction of such courts for the purpose of any such suit, action or proceeding. A final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. To the extent that service of process by mail is permitted by applicable Law, each party irrevocably consents to the service of process in any such suit,
action or proceeding in such courts by the mailing of such process by registered or certified mail, postage prepaid, at its address for notices provided for herein. Each party irrevocably agrees not to assert (a) any objection that it may ever
have to the laying of venue of any such suit, action or proceeding in any Federal or state court located in the Commonwealth of Virginia and (b) any claim that any such suit, action or proceeding brought in any such court has been brought in an
inconvenient forum. Each party waives any right to a trial by jury, to the extent lawful. 
 9.13 No Other Duties. 
 The only duties and obligations of the parties are as specifically set forth in this Agreement, and no other duties or obligations shall be implied in
fact, law or equity, or under any principle of fiduciary obligation. 
 9.14 Reliance on Counsel and Other Advisors. 
 Each party has consulted such legal, financial, technical or other expert as it deems necessary or desirable before entering into this Agreement. Each
party represents and warrants that it has read, knows, understands and agrees with the terms and conditions of this Agreement. 
  

 69 

 9.15 Release by Shareholders. 
 Each of the undersigned Shareholders hereby irrevocably waives and releases (a) Synergy or any of the Acquired Subsidiaries (or any of their
respective successors and assigns) and their respective officers, directors, employees, stockholders, agents and affiliates officers, directors, agents or representatives; (b) each of the Pension Plans; and (c) each of the Pension Plan
Fiduciaries (collectively the “Released Parties”) from each and every claim, demand, account, debt, obligation, representation and each and every right and cause of action whatsoever (known or unknown, suspected or unsuspected),
whether at law or in equity, that Shareholder or its successors, assigns, subsidiaries or affiliates now has or ever had, or that that Shareholder or its successors, assigns, subsidiaries or affiliates may hereafter have or assert against the
Released Parties from the beginning of the earth until the date hereof, arising out of any act, transaction, matter or thing. 
 9.16
Counterparts. 
 This Agreement may be executed in any number of counterparts with the same effect as if all signatory parties had
signed the same document. All counterparts shall be construed together and shall constitute one and the same instrument.

Exhibit B-4 (the “Re-Award Escrow Agreement” and together with the Balance Sheet Escrow Agreement, the General Indemnity Escrow Agreement, and the Earn Out Escrow Agreement, being hereinafter collectively referred to as the
“Escrow Agreements”). The escrow accounts set up by the Escrow Agent with respect to each of the Escrow Agreements are hereinafter individually referred to as an “Escrow Account” and collectively as the
“Escrow Accounts.” The aggregate amount held in the Escrow Accounts by the Escrow Agent at any time and from time to time, together with any interest or appreciation thereon, shall be referred to as the “Escrowed
Funds” with that portion of the Escrowed Funds held from time to time in the Balance Sheet Escrow Account being hereinafter sometimes referred to as the “Balance Sheet Escrow Funds,” that portion of the Escrowed Funds held
from time to time in the General Indemnity Escrow Account being hereinafter sometimes referred to as the “General Indemnity Escrow Funds,” that portion of the Escrow Funds held from time to time in the Earn Out Escrow Account being
hereinafter sometimes referred to as the “Earn Out Escrow Funds,” and that portion of the Escrow Funds held from time to time in the Re-Award Escrow Account being hereinafter sometimes referred to as the “Re-Award Escrow
Funds.” 
 (A) The Balance Sheet Escrow Funds shall be released and delivered to ICF or the Shareholder, as applicable, pursuant to
Section 2.3(e). 
 (B) Upon the expiration of the Survival Date, the Escrow Agent shall release and deliver to the Shareholder the
amount then remaining in the General Indemnity Escrow Account, if any, less the amount of any pending claims all as more particularly described and in accordance with the provisions of Section 9.3(a). As any pending indemnification claims
referenced in the previous sentence are resolved, the Escrow Agent, after making any payments related to such claims, shall release and deliver to the Shareholder any amounts remaining from the amounts reserved for the released claims. Any earnings
on the General Indemnity Escrow Funds, net of escrow expenses and taxes, shall be paid, pro rata, to the parties receiving distributions from the General Indemnity Escrow Account. 
  

 13 

 (C) The Earn Out Escrow Funds shall be released and delivered to ICF, or the Shareholder, as applicable,
pursuant to Section 2.2(b). 
 (D) The Re-Award Escrow Funds shall be released and delivered to ICF, or the Shareholder, as applicable,
pursuant to Section 2.2(c). 
 (b) Earn Out. 
 (i) Depending on “Gross Profits” of Caliber during the “Earn Out Period” as those terms are defined below, the Shareholder shall be entitled to receive up to $1,500,000 from the Earn Out Escrow
pursuant to this Section 2.2(b) (the “Earn Out”). If Caliber’s Gross Profits for the period from October 1, 2005 through December 31, 2006 (the “Earn Out Period”) is equal to or greater than
$28,654,000 (the “Target Gross Profit”), then the Escrow Agent shall pay to the Shareholder from the Earn Out Escrow One Million Five Hundred Thousand Dollars ($1,500,000) (the “Full Earn Out Amount”). In the event
that Gross Profit is less than Target Gross Profit but exceeds $24,356,000 (the “Threshold Gross Profit”), the Shareholder shall be entitled to receive from the Earn Out Escrow an amount equal to the product of the Full Earn Out
Amount multiplied by a fraction, the numerator of which is an amount equal to the actual Gross Profit less the Threshold Gross Profit and the denominator of which is the Target Gross Profit less the Threshold Gross Profit. In the event that Gross
Profit is less than the Threshold Gross Profit, no Earn Out shall be payable. Caliber’s “Gross Profits” means Caliber’s gross revenue with respect to the five consecutive fiscal quarters falling within the Earn Out Period
less Caliber’s direct costs (including direct labor, direct consultant, direct subcontract, and other direct costs, but excluding ICF’s corporate overhead allocations and direct fringe benefits) for that period, multiplied by 1.01. Prior
to the use by a business unit of ICF or any of its Affiliates (excluding Caliber or the Acquired Subsidiaries) (each a “Business Unit”) of any Caliber employee (including, without limitation, Caliber and former Caliber employees rendering
information technology services to or on behalf of Caliber) during the Earn Out Period on projects where the revenue therefrom would not otherwise be included in Caliber’s gross revenues, the Shareholder’s Representative and the lead
manager of such Business Unit shall negotiate in good faith and agree as to the portion of revenue generated by the utilization of such Caliber employee(s) (less applicable direct costs) on such Business Unit’s project that would be attributed
to Caliber. Prior to the material and active participation of one or more Caliber employees (including, without limitation, Caliber and former Caliber employees rendering information technology services to or on behalf of Caliber) during the Earn
Out Period in a successful bid, proposal, or other business development activity of a Business Unit, the Shareholder’s Representative and the lead manager of such Business Unit shall negotiate in good faith and agree as to the number of Caliber
employees to be utilized on the resulting project(s), and as to the portion of revenue generated by such utilization of any Caliber employee(s) (less applicable direct costs) on the resulting project(s) that would be attributed to Caliber. If there
is a dispute regarding the portion of revenue that would be attributed to Caliber that cannot be resolved between the Shareholder’s Representative and the lead manager of such Business Unit, then the ICF Chief Operating Officer will make the
final determination. ICF agrees that any such revenue during the Earn Out Period agreed to be allocated to Caliber pursuant to the preceding sentence shall be included in Caliber’s gross revenues for purposes of determining Caliber’s Gross
Profits. 
  

 14 

 (ii) The amounts, if any, due the Shareholder for the Earn Out shall be computed by ICF within thirty
(30) days following the completion of ICF’s financial audit for the calendar year 2006 and such computation, together with reasonably detailed support, will be provided to the Shareholder’s Representative. If within thirty
(30) days following delivery of such computation and support, the Shareholder’s Representative has not given ICF notice of his objection to the computation (which notice must contain a statement in reasonable detail of the basis of any
such objection), then such computation shall be final. If the Shareholder’s Representative gives notice of an objection, the parties shall use their respective best efforts to resolve any dispute by negotiation. If such dispute cannot be
settled by negotiation within thirty (30) days after ICF’s receipt of the Shareholder’s Representative’s notice, the dispute shall be resolved in accordance with the Financial Issue Resolution Process set forth in
Section 2.4. The payments, if any, of any Earn Out shall be made by the Escrow Agent from the Earn Out Escrow within five (5) business days after the finalization of the computation referred to in this Section 2.2(b). Any amounts
remaining in the Earn Out escrow at the time the amount of the Earn Out payment is finalized and paid to the Shareholder shall be paid to ICF. All earnings on the Earn Out Escrow Funds, net of escrow expenses, shall be paid to ICF at least annually.

(iv) for the purposes of determining whether an extension of a Selected Contract shall permit a later award of a successor contract to be considered a Re-Award, the value of the extension as determined pursuant to clause (i), (ii) or
(iii) of this definition, as applicable, as if the extended period were a successor contract to such Selected Contract, provided the funded value or revenues received from the extension, as applicable, shall be annualized based on the length of
the period of the extension. 
 “Current Value” of a Selected Contract means the revenues Caliber received in calendar year
2005 from that contract. 
 “Maximum Re-Award Payment” for a Selected Contract means the Re-Award Payment for that Selected

(x) is on terms (including, but not limited to, price, but excluding period of performance and value) substantially similar to the applicable Selected Contract, (y) has a period of performance (including option periods) equal to or longer
than the period of performance (including option periods) of the applicable Selected Contract (provided, a period of performance of not less than three years, including option periods, shall be deemed to satisfy this clause (y)), and
(z) in the case of each Selected Contract other than the NCCIC Contract has a Base Period Value to Caliber, ICF, or one of ICF’s Affiliates equal to at least seventy-five percent (75%), or more, of the Current Value of the applicable
Selected Contract (and in the case that the applicable Selected Contract is the NCCIC Contract, has a Base Period Value to Caliber, ICF, or one of ICF’s Affiliates equal to at least forty-five percent (45%), or more, of the Current Value of the
NCCIC Contract). A Selected Contract shall also be considered to have been Re-Awarded if it is first extended for up to a year beyond the current scheduled end date of the Selected Contract, on the same terms as and for a Base Period Value equal to
or greater than seventy-five percent (75%) of the Current Value of the Selected Contract, and is thereafter Re-Awarded to Caliber at or prior to the expiration of the extended term. 
 “Re-Award Payment” has the meaning set forth in Section 2.2(c)(ii) below. 
 “Re-Award Payment Percentage” has the meaning set forth in Section 2.2(c)(ii)(B) below. 
 “Selected Contract” means any one of the Selected Contracts set forth in the table above. 
  

 16 

 (ii) Based upon whether Caliber is Re-Awarded any of the Selected Contracts, the Shareholder shall be

 (A) If the Base Period Value of the Re-Awarded contract is equal to at least one hundred percent (100%) of the Current Value of the applicable Selected Contract, then the Re-Award Payment with respect to that
Re-Awarded contract shall be the applicable Maximum Re-Award Payment for the applicable Selected Contract. 
 (B) If the Base Period Value
of the Re-Awarded contract to Caliber, ICF, or one of its Affiliates is equal to at least seventy-five percent (75%) (or forty-five percent (45%) in the case of the NCCIC Contract), but less than one hundred percent (100%) of the
Current Value of that contract (in each case the “Re-Award Payment Percentage”), then the Re-Award Payment with respect to that Re-Awarded contract shall be an amount equal to the product of the applicable Maximum Re-Award Payment
for the applicable Selected Contract multiplied by the Re-Award Payment Percentage (between seventy-five percent (75%) and one hundred percent in the case of each Selected Contract other than the NCCIC Contract and between forty-five percent
(45%) and one hundred percent in the case of the NCCIC Contract). For any Re-Award Payment to be made, the proposal to obtain the Re-Awarded Selected Contract must be prepared and approved in advance of submission pursuant to ICF’s
applicable policies and procedures, and the Re-Awarded Selected Contract must be approved in advance of execution pursuant to ICF’s applicable policies and procedures. If (x) the Base Period Value of any successor Selected Contract to
Caliber, ICF, or one of its Affiliates is less than seventy five percent (75%) (or forty-five percent (45%) in the case of the NCCIC Contract) of the Current Value of that Selected Contract, or (y) Caliber, ICF, or one of its
Affiliates is not Re-Awarded the Selected Contract in 2006, or (z) the Selected Contract is extended, as described above, and Caliber, ICF, or one of its Affiliates is not Re-Awarded the Selected Contract at or prior to the expiration of the
extended term, then there shall be no Re-Award Payment with respect to that contract. 
 (iii) The amounts, if any, due the Shareholder for
any Re-Award Payment shall be computed within thirty (30) days following the (a) later of the actual start of work by Caliber on the Re-Awarded Selected Contract or the expiration of the applicable time period for the filing of a protest
or any other applicable challenge with respect to the Re-Awarded Selected Contract in the case of the Selected Contracts where the Base Period Value is calculated based on the level of funding in the initial period of performance of the contract as
awarded, or (b) the closing of the financial books of ICF for the twelfth month following the award of the Re-Awarded Selected Contract in the case of the Selected Contracts where the Base Period Value is calculated based on the revenues
generated under the contract for Caliber during the first twelve months after contract award, or (c) the closing of the financial books of ICF for 2007 where revenues for calendar year 2007 are used to determine the Base Period Value.
Such computation, together with reasonably detailed support, will be provided to the Shareholder’s Representative. If within thirty (30) days following delivery of such computation and support, the Shareholder’s Representative has not
given ICF notice of his objection to the computation (which notice must contain a statement in reasonable detail of the basis of any such objection), then such computation shall be final. If the Shareholder’s Representative gives notice of an
objection, the parties shall use their respective best efforts to resolve any dispute by negotiation. 
  

 17 

 If such dispute cannot be settled by negotiation within thirty (30) days after ICF’s receipt of the
Shareholder’s Representative’s notice, the dispute shall be resolved in accordance with the Financial Issue Resolution Process set forth in Section 2.4. The payment, if any, of any Re-Award Payment shall be made by the Escrow Agent
from the Re-Award Escrow within five (5) business days after the finalization of the computation referred to in this Section 2.2(c). All amounts remaining in the Re-Award Escrow as of March 31, 2007 shall be returned to ICF, unless:

 (x) one or more Selected Contracts have been extended beyond the current scheduled end date of the Selected Contract, on the same terms as
and for a Base Period Value equal to or greater than seventy-five percent (75%) of the Current Value of the Selected Contract, but such Selected Contract has not yet been Re-Awarded, in which case an amount equal to the maximum Re-Award Payment
for that Selected Contract shall remain in the Re-Award Escrow until the earlier of the date any Re-Award Payment is made with respect to that Selected Contract or March 31, 2008, at which time all amounts remaining in the Re-Award Escrow shall
be returned to ICF except with respect to Re-Award Payments relating to Selected Contracts as provided in clause (y) of this sentence; or 
 (y) a successor contract to one or more of the Selected Contracts has been awarded to Caliber, ICF, or its Affiliates for which the Base Period Value depends on the revenues generated in 2007 or the first twelve months after contract award,
but the period for calculating the Re-Award Payment has not yet run, in which case an amount equal to the maximum Re-Award Payment for that Selected Contract shall remain in the Re-Award Escrow until the earlier of the date any Re-Award Payment is
made with respect to that Selected Contract or 90 days after the end of that twelve-month period, at which time all amounts remaining in the Re-Award Escrow shall be returned to ICF except with respect to Re-Award Payments relating to Selected
Contracts as provided in clause (x) of this sentence. 
 Notwithstanding the preceding sentence, undisputed amounts payable as a result of one or more
Re-Awarded Selected Contracts but not yet paid as of the date or dates remaining amounts in the Re-Award Escrow are to be returned to ICF, shall be distributed to the Shareholder on such date or dates, as applicable. All earnings on the Re-Award
Escrow Funds, net of escrow expenses, shall be paid to ICF. 
 2.3 Estimated Closing Cash Purchase Price and Net Working Capital
Adjustments. 
 (a) Estimated Closing Cash Purchase Price. The estimated cash portion of the Purchase Price (the “Estimated
Closing Cash Purchase Price”) payable to the Shareholder at Closing shall be an amount equal to Nineteen Million Dollars ($19,000,000) as adjusted upward or downward pursuant to Sections 2.3(b) and (c) below and as reduced by the
Scheduled Transaction Costs. The Estimated Closing Cash Purchase Price shall be paid by ICF to the Shareholder. 
 (b) Not less than two
(2) Business Days prior to the Closing Date, the Shareholder shall deliver to ICF an estimated, unaudited balance sheet (the “Estimated Closing Balance Sheet”) of Caliber as of the Closing Date, together with all supporting
documentation. The Estimated Closing Balance Sheet shall include cash/accrual taxes of Caliber and shall be 
  

 18 

 prepared by Caliber’s controller and reviewed by Caliber’s external auditors, in accordance with GAAP and in a
manner consistent with the December 2004 Balance Sheet except that the Estimated Closing Balance Sheet shall include a calculation of the “Adjusted Closing Net Working Capital” (hereinafter defined). For purposes of this Agreement, the
terms “Adjusted Closing Net Working Capital” and “Closing Net Working Capital” shall have the following meanings. 
 (i)
The term “Adjusted Closing Net Working Capital” shall mean the “Closing Net Working Capital” (as hereinafter defined and as adjusted pursuant to Section 2.3(d) below) of Caliber as shown on the Estimated Closing
Balance Sheet as reduced to reflect, to the extent not otherwise reflected in the Closing Net Working Capital or the calculation of Closing Cash: (A) the payment in full of any and all outstanding indebtedness of Caliber and the Acquired
Subsidiaries, including, but not limited to, any indebtedness that Caliber or the Acquired Subsidiaries may have to the Caliber ESOP, the ESOP Sponsor, or any third party; (B) the payment of the Transaction Costs other than the Scheduled
Transaction Costs (including (1) any payments due Caliber employees resulting from the Contemplated Transactions and (2) the accrual or full funding, through the Effective Date, of all qualified or unqualified Pension Plans);
(C) payment of the Subsidiary Capitalization Amount; and (D) the Accrued Bonuses. 
 (ii) The term “Closing Net Working
Capital” shall mean the amount as of the Closing Date and as shown by the Closing Balance Sheet by which Caliber’s current assets (exclusive of cash and inclusive of accounts receivable, unbilled receivables, income taxes and other
currents assets) exceed current liabilities (exclusive of the line of credit and current portions of subordinated notes payable to employees, which will be repaid at Closing, and inclusive of accounts payable and accrued expenses, accrued payroll
and related liabilities, billings in excess of revenue recognized and deferred rent), all calculated in accordance with GAAP in a manner consistent with the December 31, 2004 Financial Statements. 
 (iii) The term “Closing Cash” shall mean Caliber’s cash on the Closing Date, as reduced to reflect (A) the payment in full of
any and all outstanding indebtedness of Caliber and the Acquired Subsidiaries, including, but not limited to, any other indebtedness that Caliber or the Acquired Subsidiaries may have to the Caliber ESOP, the ESOP Sponsor, or any third party; and
(B) payment of the Subsidiary Capitalization Amount. 
 (c) Adjustments to Estimated Closing Cash Purchase Price. The Estimated
Closing Cash Purchase Price will be adjusted (i) downwards on a dollar-for-dollar basis to the extent that the Adjusted Closing Net Working Capital, as shown on the Estimated Closing Balance Sheet, is below the Base Net Working Capital Range
and (ii) upwards on a dollar-for-dollar basis to the extent that the Adjusted Closing Net Working Capital is above the Base Net Working Capital Range. The Estimated Closing Cash Purchase Price will be further adjusted (i) downwards on a
dollar-for-dollar basis to the extent that the Closing Cash is less than zero and (ii) upwards on a dollar-for-dollar basis to the extent that the Closing Cash is greater than zero. 
 (d) Closing Balance Sheet and Adjusted Closing Net Working Capital. Promptly following the Closing, ICF will cause Grant Thornton LLP to review
the Estimated Closing Balance Sheet, including the Adjusted Closing Net Working Capital, the Closing Net Working Capital and the Closing Cash as reflected thereon. Based on such review, ICF will 
  

 19 

 deliver a proposed Closing Balance Sheet, prepared in a manner consistent with Section 2.3(b) above together with
all related work papers, to the Shareholder’s Representative within fifteen (15) Business Days after the later of (i) the Closing Date, or (ii) the date of receipt by ICF of all information sufficient for ICF to complete its
review of all aspects of the Estimated Closing Balance Sheet (the “Proposed Closing Balance Sheet”). If within fifteen (15) Business Days following delivery of the Proposed Closing Balance Sheet, the Shareholder’s
Representative has not given ICF notice of his objection to the Proposed Closing Balance Sheet (which notice must contain a statement in reasonable detail of the basis of any such objection), then such Proposed Closing Balance Sheet shall constitute
the “Closing Balance Sheet,” and the Adjusted Closing Net Working Capital, Closing Net Working Capital and Closing Cash amounts included therein shall constitute the “Adjusted Closing Net Working Capital,” “Closing
Net Working Capital” and “Closing Cash.” If the Shareholder’s Representative gives notice of an objection, the parties shall use their respective best efforts to resolve any dispute by negotiation. If such dispute cannot be
settled by negotiation within thirty (30) days after receipt by ICF of the Shareholder’s Representative’s notice, the dispute shall be resolved in accordance with the Financial Issue Resolution Process set forth in Section 2.4.

 (e) Final Adjustment to the Estimated Closing Cash Purchase Price. If the Adjusted Closing Net Working Capital and the Closing Cash
are such that Sections 2.3(d) and/or 2.4 do not require an adjustment to the Estimated Closing Cash Purchase Price, then the Escrow Agent shall disburse to the Shareholder the Balance Sheet Escrow within five (5) days after the finalization of
the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4. If the Adjusted Closing Net Working Capital or the Closing Cash are such that Sections 2.3(d) or 2.4 require an adjustment to the Estimated Closing Cash Purchase Price, any amount due
to the Shareholder by ICF in excess of the Balance Sheet Escrow shall be paid by ICF to the Shareholder, and any amount due to ICF from the Shareholder shall be paid to ICF by the Escrow Agent from the Escrow and, if the amount due ICF is in excess
of the Balance Sheet Escrow, then such excess shall be paid to ICF by the Shareholder, all payments to be made within five (5) days after the finalization of the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4. In the event that
the Shareholder for any reason fails to make the payment contemplated in the previous sentence, then ICF may bring an indemnification claim under Article IX and the Shareholder and the Founders shall be jointly and severally liable for that payment
in accordance with Article IX. Any earnings on the Balance Sheet Escrow Funds, net of escrow expenses and taxes, shall be paid, pro rata, to the parties receiving distributions from the Balance Sheet Escrow Account. 
 2.4 Financial Issue Resolution Process. 
 Disputes between ICF and the Shareholder’s Representative that cannot be resolved by negotiation within thirty (30) days after receipt by ICF of the Shareholder’s Representative’s notice in accordance with Sections
2.2(b) or 2.3(d) shall be referred no later than such 30th day for decision to RSM McGladrey, provided if at such time they serve as the independent public accountants of ICF or are otherwise unavailable for any reason, then to a
nationally-recognized independent public accounting firm mutually selected by the Shareholder’s Representative and ICF (which firm shall not be either (a) the independent public accountants of ICF or (b) the independent public
accountants used by Caliber prior to the Closing Date) (the “Auditor”) who shall act as arbitrator and determine, based solely on presentations by the Shareholder’s Representative and ICF and only with respect to the

  

 20 

 remaining differences so submitted. If RSM McGladrey is ineligible to serve or is otherwise unavailable and such an
alternate accounting firm cannot be identified within ten (10) business days after the identification of the need for dispute resolution, the dispute shall be resolved in accordance with Section 11.11. The Auditor shall deliver its written
determination to ICF and the Shareholder’s Representative no later than the 30th day after the remaining differences underlying the dispute are referred to the Auditor, or such longer period of time as the Auditor determines is necessary. The
Auditor’s determination shall be conclusive and binding upon the parties. The fees and disbursements of the Auditor shall be allocated equally between ICF and the Shareholder’s Representative. ICF and the Shareholder shall make readily
available to the Auditor all relevant information, books and records and any work papers relating to the dispute and all other items reasonably requested by the Auditor. In no event may the Auditor’s resolution of any difference be for an
amount that is outside the range of ICF’s and the Shareholder’s Representative’s disagreement. 
 2.5 Shareholder’s
Representative. 
 (a) Croan is hereby appointed as the Shareholder’s and the Founders’ true and lawful representative, proxy,
agent and attorney-in-fact (the “Shareholder’s Representative”) for a term that shall be continuing and indefinite and without a termination date except as otherwise provided herein, to act for and on behalf of the Shareholder
and the Founders in connection with or relating to the Transaction Documents and the Contemplated Transactions, including, without limitation, to give and receive notices and communications, to receive and accept service of legal process in
connection with any proceeding arising under the Transaction Documents or in connection with the Contemplated Transactions, to authorize delivery of cash from each of the Escrow Accounts, to object to or accept any claims against or on behalf of the
Shareholder and/or the Founders pursuant to Article IX, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such amounts or claims, and
to take all actions necessary or appropriate in the sole opinion of the Shareholder’s Representative for the accomplishment of the foregoing. Until all amounts in each of the Escrow Accounts have been fully and finally been distributed by the
Escrow Agent, the Shareholder may remove and replace any Shareholder’s Representative. At such time as all amounts in each of the Escrow Accounts have been fully and finally distributed by the Escrow Agent, the Shareholder shall cease to have
the authority to remove and replace the Shareholder’s Representative and Croan shall have the authority to remove and replace any Shareholder’s Representative. Any change in the Shareholder’s Representative shall become effective only
upon delivery of written notice of such change to ICF. The Shareholder’s Representative shall not receive compensation for his or her services. Notices, deliveries or communications to or from the Shareholder’s Representative by or to any
of the parties to the Transaction Documents shall constitute notices, deliveries or communications to or from the Shareholder. 
 (b) The
Shareholder’s Representative shall not be liable for any act done or omitted hereunder in his capacity as Shareholder’s Representative in the absence of gross negligence or willful misconduct on his or her part. The Shareholder and the
Founders (so long as the Shareholder has the authority to remove and replace the Shareholder’s Representative) and the Founders, but not the Shareholder (commencing at the time Croan has the authority to remove and replace the
Shareholder’s Representative) shall protect and indemnify the 
  

 21 

 Shareholder’s Representative and hold the Shareholder’s Representative harmless from and against any and all
damages, actions, proceedings, demands, liabilities, losses, taxes, fines, penalties, costs, claims and expenses (including, without limitation, reasonable fees of counsel) (“Damages”) of any kind or nature whatsoever (whether or
not arising out of third-party claims and including all amounts paid in investigation, defense or settlement of the foregoing) that may be sustained or suffered by the Shareholder’s Representative in connection with the administration of its
duties hereunder, except where such Damages arise from or are the result of the Shareholder’s Representative’s gross negligence or willful misconduct. 
 (c) Any decision, act, consent or instruction taken or given by the Shareholder’s Representative pursuant to this Agreement shall be and constitute a decision, act, consent or instruction of the Shareholder
and/or the Founders, as the case may be, and shall be final, binding and conclusive upon the Shareholder and the Founders. The Escrow Agent and ICF may rely upon any such decision, act, consent or instruction of the Shareholder’s Representative
as being the decision, act, consent or instruction of the Shareholder and/or the Founders and shall have no duty to inquire as to the acts and omissions of the Shareholder’s Representative. The Escrow Agent and ICF are hereby relieved from any
liability to any Person for any acts done by them in accordance with such decision, act, consent or instruction of the Shareholder’s Representative. 
 (d) Notices given to the Shareholder’s Representative in accordance with Section 11.2 shall constitute notice to the Shareholder and the Founders for all purposes under this Agreement. 
 (e) This Section 2.5 shall survive the termination or expiration of this Agreement or any one or more of the Escrow Agreements.

 (a) Caliber has been a validly electing S corporation within the meaning of
Section 1361 of the Code (an “S Corporation”) at all times from and after January 1, 2002. The Shareholder represents that all requirements for making the election to treat Caliber as an S Corporation (the “S
Election”) were satisfied at the time the election was made and that the election was timely filed and in effect for all taxable years of Caliber for which federal and state income tax returns were filed based upon the continued validity of
such S Election. The Shareholder represents that it is a permitted shareholder of an S Corporation under Section 1361 of the Code and that the Shareholder is and has been at all times during which the S Election has been in effect, the sole
shareholder of Caliber. Caliber has, and at all times during which the S Election has been in effect, has had, only one class of common stock and does not have any outstanding options, contracts or other instruments that would constitute a second

treatment is available, and Caliber has not at any time since January 1, 2002 made any election or filing to be treated as a Subchapter C corporation for state income Tax purposes in any of those states. Caliber has no liability or obligation
to any state to pay income Tax upon any of Caliber’s taxable income that is, or has been, properly allocated to the Shareholder as a result of Caliber’s election to be treated as an S Corporation at any state or local level. Caliber has

or legal basis for such claim; 
 (g) All Tax deficiencies asserted or assessed against the Taxpayers have been paid or finally settled with

nor Caliber shall be required to take any action that would constitute a waiver of the attorney-client or other privilege and (c) neither ICF nor Caliber need supply the Shareholder, the Founders, or their representatives with any information

Section 5.8 will be inadequate, and that ICF shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Section 5.8 and to enforce specifically the terms and provisions thereof, in addition to any other
remedy to which ICF may be entitled at law or equity. 
 (f) Should any provision of this Section 5.8 be determined to be unenforceable
or prohibited by any applicable law, such provision shall be ineffective to the extent, and only to the extent, of such unenforceability or prohibition without invalidating the balance of such provision or any other provision of this
Section 5.8, and any such unenforceability or prohibition in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
 (g) In consideration of the Founders agreeing to this Section 5.8, ICF agrees to make those payments to the Founders at those times shown on Exhibit C. In addition, under the terms of the Key Employee
Offer Letters, each of the Key Employees is required to agree to certain non-compete and non-solicitation covenants for which each Key Employee will receive compensation as provided therein. All payments due under this Section 5.8 are
hereinafter collectively referred to as the “Non-Compete/Non-Solicitation Payments.” 
 5.9 No Solicitation of
Competitive Transactions. 
 During the period from the date hereof through the earlier to occur of (a) the Closing Date and
(b) the termination of this Agreement in accordance with Article X, the Shareholder shall not permit Caliber or the Acquired Subsidiaries, and Caliber and the Founders will not (nor shall any of them permit any of their respective officers,

 58 

 5.10 Personnel. 
 (a) For purposes of this Agreement, Caliber’s Personnel as of the Closing Date shall be categorized sometimes as (i) the Founders, (ii) the “Key Employees” (which shall mean and refer
to those employees listed on Exhibit E), (iii) the “Non-Key Employees” (which shall refer to all employees of Caliber as of the Closing Date other than the Founders and the Key Employees), and (iv) “Non-Key
Billable Employees” (which shall refer to those Non-Key Employees who are billable to customers of Caliber or an Acquired Subsidiary, as applicable). 
 (b) The Founders shall be required to sign employment agreements in the form attached hereto as Exhibit F (the “Croan / Bishop Employment Agreements”). 
 (c) Prior to the Closing each of the Key Employees will receive and shall be required, as a condition of employment, to countersign where appropriate and
return to ICF the documents contained in an offer package that shall be comprised of (i) the Standard Employee Documents and (ii) an offer letter (the “Key Employee Offer Letter”) setting forth (A) the non-compete
provisions that each Key Employee is expected to abide by and on which their employment with ICF is contingent (and the Non-Compete / Non-Solicitation Payments that the Key Employee is entitled to) and (B) the performance bonus that the Key
Employee may earn, subject to management’s evaluation of the Key Employee’s contributions. 
 (d) Each Non-Key Employee shall
receive and, as a condition of employment, be required to sign and return a confirmation accepting continued employment, ICF’s standard agreements, ICF’s Code of Ethics and a Degree Verification form, all in the form attached hereto and
incorporated herein as Exhibit G (hereinafter collectively the “Standard Employee Documents”). 
 (e) From and after the
Closing Date, any Key or Non-Key Employee who signs the documents contained in the Key Employee Offer Letter and/or the Standard Employee Documents, as applicable, and chooses to become an employee of ICF shall be given (to the extent he or she
elects to participate and it is permitted by Law), credit for past service with Caliber for purposes of participation and vesting in any employee benefit plan offered by ICF. 
 5.11 Certain Tax Matters. 
 (a) Tax
Periods Ending on or Before the Effective Date. ICF shall prepare, or cause to be prepared, and file, or cause to be filed, on a timely basis (in each case, at its sole cost and expense) and on a basis reasonably consistent with past practice
(unless ICF is advised otherwise by its outside tax consultants), all Tax Returns with respect to Caliber and the Acquired Subsidiaries for taxable periods ending on or prior to the Effective Date and required to be filed thereafter (the
“Prior Period Returns”). ICF shall provide a draft copy of such Prior Period Returns to the Shareholder’s Representative for its review at least fifteen (15) Business Days prior to the due date thereof. The
Shareholder’s Representative shall provide its comments to ICF at least five Business Days prior to the due date of such returns, and ICF shall make all changes requested by the Shareholder’s Representative in good faith (unless ICF is
advised in writing by its independent outside accountants or attorneys that such changes (i) are contrary to applicable Law, or (ii) will or are likely to have a material adverse effect on ICF or any of its 
  

 59 

 Affiliates). Except as provided in Section 5.11(c), and only to the extent such Taxes have not been accrued or
otherwise reserved for on the Closing Balance Sheets, all Taxes with respect to Caliber and the Acquired Subsidiaries shown to be due on such Prior Period Returns shall be the responsibility of the Shareholder. In the event that the Shareholder for
any reason fails to make the payment contemplated in the previous sentence, then ICF may bring an indemnification claim under Article IX and the Shareholder and the Founders shall be jointly and severally liable for that payment. 
 (b) Tax Periods Beginning Before and Ending After the Effective Date. 
 (i) ICF shall prepare or cause to be prepared and file or cause to be filed, on a basis reasonably consistent with past practice, any Tax Returns of
Caliber and the Acquired Subsidiaries for Tax periods that begin before the Effective Date and end after the Effective Date (“Straddle Periods”). ICF shall permit the Shareholder’s Representative to review and comment on each
such Tax Return described in the preceding sentence at least fifteen (15) Business Days prior to the due date thereof, and ICF shall make all changes reasonably requested by the Shareholder’s Representative in good faith (unless ICF is
advised in writing by its independent outside accountants or attorneys that such changes (i) are contrary to applicable Law, or (ii) will, or are likely to have a material adverse effect on ICF or any of its Affiliates). Within fifteen
(15) days after the date on which ICF pays any Taxes of Caliber and the Acquired Subsidiaries with respect to any Straddle Period, the Shareholder shall, to the extent such Taxes have not been accrued or otherwise reserved for on the Closing
Balance Sheets, pay to ICF the amount of such Taxes that relates to the portion of such Straddle Period ending on the Effective Date (the “Pre-Closing Tax Period”). In the event that the Shareholder for any reason fails to make the
payment contemplated in the previous sentence, then ICF may bring an indemnification claim under Article IX and the Shareholder and the Founders shall be jointly and severally liable for that payment. 
 (ii) For purposes of this Agreement: 
 (1)
In the case of any gross receipts, income, or similar Taxes that are payable with respect to a Straddle Period, the portion of such Taxes allocable to (A) the Pre-Closing Tax Period and (B) the portion of the Straddle Period beginning on
the day next succeeding the Effective Date (the “Post-Closing Tax Period”) shall be determined on the basis of a deemed closing at the end of the Effective Date of the books and records of Caliber. 
 (2) In the case of any Taxes (other than gross receipts, income, or similar Taxes) that are payable with respect to a Straddle Period, the portion of
such Taxes allocable to the portion of the Straddle Period prior to the Effective Date shall be equal to the product of all such Taxes multiplied by a fraction the numerator of which is the number of days in the Straddle Period from the commencement
of the Straddle Period through and including the Effective Date and the denominator of which is the number of days in the entire Straddle Period; provided, however, that appropriate adjustments shall be made to reflect specific events that
can be identified and specifically allocated as occurring on or prior to the Effective Date (in which case the Shareholder shall be responsible for any Taxes related thereto) or occurring after the Effective Date (in which case, ICF shall be
responsible for any Taxes related thereto). 
  

 60 

 (iii) ICF shall be responsible for (1) any and all Taxes with respect to the Pre-Closing Tax Period
of each Straddle Period to the extent such Taxes have been accrued or otherwise reserved for on the Closing Balance Sheet and (2) any Taxes with respect to the Post-Closing Tax Period of each Straddle Period. 
 (c) Cooperation on Tax Matters. 
 (i)
ICF, the Shareholder, and the Founders shall cooperate fully, as and to the extent reasonably requested by any party, in connection with the filing of Tax Returns pursuant to this Section and any audit, litigation, or other proceeding with respect
to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information reasonably relevant to any such audit, litigation, or other proceeding and making their respective employees,
outside consultants and advisors available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. ICF, the Shareholder, and the Founders agree (A) to retain all books and records
with respect to Tax matters pertinent to Caliber and the Acquired Subsidiaries relating to any taxable period beginning before the Effective Date until the expiration of the statute of limitations (and, to the extent notified by ICF or the
Shareholder’s Representative, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the others reasonable written notice prior to
transferring, destroying or discarding any such books and records and, if the other so requests, ICF, the Shareholder, or the Founders, as the case may be, shall allow one of the others to take possession of such books and records. 
 (ii) ICF, the Shareholder and the Founders further agree, upon request, to use their best efforts to obtain any certificate or other document from any
Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby). 
 (iii) ICF, the Shareholder and the Founders further agree, upon request, to provide the other party with all information that either party may be
required to report pursuant to Section 6043 of the Code and all Treasury Department Regulations promulgated thereunder. 
 (d)
Certain Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any penalties and interest) incurred in connection with the Contemplated Transactions (including any transfer or similar tax
imposed by any governmental authority) shall be shared equally between ICF on the one hand and the Shareholder and the Founders on the other, and each shall be responsible for one-half of such Taxes. The party required by Law to do so will file all
necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, registration and other Taxes and fees, and, if required by applicable Law, the other parties will join in the execution of any such Tax
Returns and other documentation. 
  

 61 

 5.12 Public Announcements. 
 No one of ICF, Caliber, any of the Acquired Subsidiaries, the Shareholder, or either of the Founders will issue any press release or make any public
statement with respect to this Agreement or the Contemplated Transactions, or disclose the existence of this Agreement to any Person or entity, prior to the Closing and, after the Closing, will not issue any such press release or make any such
public statement without the prior consent of the other parties (which consent shall not be unreasonably withheld or delayed), subject to any applicable disclosure obligations pursuant to Applicable Law, provided that the party proposing to
issue any press release or similar public announcement or communication in compliance with any such disclosure obligations shall use commercially reasonable efforts to consult in good faith with the other party before doing so. 
 5.13 Communications with Customers and Suppliers. 
 The Shareholder and ICF will mutually agree upon all communications with suppliers and customers of Caliber relating to this Agreement and the Contemplated Transactions prior to the Closing Date. 
 5.14 [Intentionally Omitted]. 
 5.15
Assumption of Caliber ESOP. 
 Prior to the Closing the Shareholder shall cause the following to occur: (i) Caliber shall make a
contribution to the capital of the ESOP Sponsor Subsidiary in the amount of $409,100.00 (the “Subsidiary Capitalization Amount”), (ii) the ESOP Sponsor Subsidiary shall adopt and assume the Caliber ESOP and shall succeed to all
rights and obligations of Caliber thereunder, (iii) Caliber shall transfer all of its right, title, and interest in the issued and outstanding shares of capital stock of the ESOP Sponsor Subsidiary to one or more persons or entities designated
by the trustee of the Caliber ESOP, and (iv) the ESOP Sponsor Subsidiary’s board of directors shall adopt a resolution terminating the Caliber ESOP effective upon completion of the Closing. 
 5.16 Post-Closing Covenants Relating to Caliber ESOP. 
 At the Closing, Caliber shall cause the ESOP Subsidiary to deliver to ICF a completed Form 5310 determination letter application with a written statement (in a form satisfactory to ICF’s legal counsel) that
discloses the pre-Closing assumption of the Caliber ESOP by the ESOP Sponsor Subsidiary (the “Form 5310 Letter”). No later than thirty (30) days after the Closing Date, the Shareholder shall cause the ESOP Sponsor Subsidiary to
file the Form 5310 Letter. In the event the Internal Revenue Service responds to such determination letter application with a proposal to disqualify the Caliber ESOP’s tax qualification solely on the basis of the ESOP Sponsor Subsidiary’s
pre-Closing assumption of the sponsorship of the Caliber ESOP from Caliber, and such proposed disqualification cannot (after exhaustion of all available appeals) successfully be eliminated by the joint efforts of legal counsel for the ESOP Sponsor
Subsidiary, the Caliber ESOP and ICF, ICF shall cause Caliber to re-assume sponsorship of the Caliber ESOP in order to prevent disqualification of the Caliber ESOP solely due to the ESOP Sponsor Subsidiary’s pre-Closing assumption of the
Caliber ESOP (the “Resumption of  
  

 62 

 Sponsorship”). ICF shall (i) cause Caliber to pay all expenses solely relating to Caliber’s
Resumption of Sponsorship, including any Internal Revenue Service Employee Plans Compliance Resolution System (“EPCRS”) sanctions or fees, (ii) in the event there is a final determination (after the exhaustion of all available
appeals) that the Caliber ESOP is irremediably disqualified solely as a result of the ESOP Sponsor Subsidiary’s pre-Closing assumption of the Caliber ESOP, indemnify, or cause Caliber to indemnify, the ESOP Sponsor Subsidiary and the Caliber
ESOP for all damages incurred by either or both relating to such irremediable disqualification. 
 5.17 Life Insurance. 
 Croan and ICF hereby agree that if ICF’s lender requires a life insurance policy to be obtained on Croan’s life as a condition to, or otherwise
as a requirement for financing then each shall use their respective best efforts to cause such a life insurance policy to be obtained and issued in the amount and for the benefit of the beneficiary (ies) designated by the lender; provided, however,
that the premium(s) payable with respect to the life insurance policy shall be payable and paid by ICF. 
 5.18 Termination of Qualified
Pension Plans. 
 Prior to the Closing, Caliber shall terminate each of its tax-qualified Pension Plans and cause the distribution of
participant accounts thereunder pursuant to the provisions of such plans. Prior to the Closing, Caliber shall provide ICF with copies of Plan documents effectuating such plan terminations. ICF shall take any necessary actions with respect to its
plan to permit the rollover of eligible rollover distributions from the Caliber’s terminated Pension Plans to an ICF plan. 
 5.19
Termination and Amendment of Nonqualified Plan. 
 Prior to the Closing, Caliber shall: (a) obtain the written consent of all
participants in the Caliber Excess Plan to the termination of such plan prior to the Closing and the distribution of all plan assets as soon as practicable thereafter; and (b) amend such plan to so provide for the plan’s termination prior
to Closing and the distribution of all assets thereunder as soon as practicable. 
 5.20 Filing of Annual Reports. 
 Prior to the Closing, Caliber shall file all annual reports (Form 5500) with respect to all Plans as required by ERISA. Caliber shall provide ICF with
copies of such filing prior to the Closing. 
 5.21 Post-Closing Operation of Caliber. 
 ICF hereby covenants and agrees that, during the Earn Out Period, ICF shall use commercially reasonable efforts to continue the business and operations of
Caliber and the Acquired Subsidiaries in the ordinary course and, to the extent consistent therewith, to use commercially reasonable efforts to preserve (a) Caliber’s respective relationships with customers, employees, suppliers, and
others having business dealings with Caliber and the Acquired 
  

 63 

 Subsidiaries, and (b) Caliber’s ability to achieve the Target Gross Profit and be Re-Awarded the Selected
Contracts. Without limiting the generality of the preceding sentence, ICF shall, during the Earn Out Period, permit Caliber to bid on proposals for re-competition of the Selected Contracts at competitive indirect labor rates comparable to the
existing indirect labor rates on each Selected Contract, as long as those indirect labor rates are consistent with the employee utilization rates and costs involved in performing those contracts. Notwithstanding the foregoing, Shareholder, Caliber,
and the Founders understand that ICF intends to (and Shareholder, Caliber and the Founders hereby acknowledge and agree that ICF and its Affiliates may) (a) remove Caliber’s current information technology staff from Caliber immediately
after Closing and combine them with other businesses of ICF or its Affiliates, (b) terminate some of Caliber’s non-billable staff after Closing (upon mutual agreement with Croan and/or Bishop during the first three (3) months after
Closing and after discussion with Croan and/or Bishop thereafter), and (c) if utilization of Caliber’s staff is less than 5% below plan at any time during 2006, as calculated on ICF’s standard reports, and after discussing possible
remedies for such shortfall with Croan and Bishop, take appropriate actions, up to and including instructing Croan, Bishop, or others to terminate sufficient Caliber staff to increase utilization to within 5% of plan. During the Earn Out Period,
Business Units (excluding Caliber or the Acquired Subsidiaries) shall only use Caliber employees on projects pursuant to Section 2.2(b)(i). In addition, prior to the use by Caliber of any employee of any Business Unit during the Earn Out
Period, the Shareholder’s Representative and the lead manager of such Business Unit shall negotiate in good faith and agree as to the portion of revenue generated by such employee that will be attributed to Caliber. ICF agrees that any such
revenue during the Earn Out Period agreed to be allocated to Caliber pursuant to the preceding sentence shall be included in Caliber’s gross revenues for purposes of determining Caliber’s Gross Profits. 
 5.22 Bonuses. 
 Following the
completion of the Closing, ICF shall cause Caliber (i) to pay fifty percent (50%) of the Accrued Bonuses to those employees eligible to receive Accrued Bonuses on or before March 15, 2006 and (ii) to pay the remaining 50% of the
Accrued Bonuses no later than November 15, 2006. The parties agree that (a) the Accrued Bonuses are only payable to Persons that were employees of Caliber or the Acquired Subsidiaries as of the Closing Date and at all times between the
Closing Date and the date of payment and (b) the amount of the Accrued Bonuses payable to each eligible employee shall be determined by Croan and Bishop, subject to approval, not to be unreasonably withheld, of ICF’s Chief Executive
Officer and the Compensation and Distribution Committee of the Board of Directors of ICF. The parties agree that the entirety of the Accrued Bonuses shall be allocated. Notwithstanding anything herein to the contrary, the parties agree that senior
Caliber employees shall remain eligible for 2006 ICF bonuses payable in 2007, consistent with ICF’s Incentive Compensation Plan practices. 
 5.23 Financing and Bank Commitment Letter. 
 Subject to the terms and conditions of this Agreement, ICF covenants and agrees
to use its best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to obtain the financing necessary to consummate the Contemplated
Transactions, including, without limitation, obtaining a bank commitment letter in respect of such financing. Upon ICF’s receipt of a bank 
  

 64 

 commitment letter satisfactory to ICF (the “Commitment Letter”) in respect of the funds necessary to
finance the Contemplated Transactions, ICF shall promptly provide a copy of such letter to Caliber and the Shareholder’ Representative. 
 5.24 Director and Officer Liability and Indemnification. 
 (a) For the 3 year period commencing on the Closing Date, Caliber
shall, and ICF shall cause Caliber to maintain, pay all premiums due under and shall not permit to lapse or terminate, a Directors and Officers insurance policy with coverage and dollar amount limits substantially similar to Caliber’s Directors
and Officers insurance in effect as of the date hereof.

amend, and shall amend, its Articles of Incorporation to add the indemnification provision set forth on Exhibit L attached hereto.

 Survival and Indemnification
 9.1 Survival of Representations and Warranties. 
 (a) Except for the Surviving Representations, the representations and warranties of the Shareholder, Caliber and the Founders on the one hand, and ICF, on
the other hand, in this Agreement or in any certificate or document delivered on or before the Closing Date shall survive any due diligence investigation by or on behalf of the parties hereto and the Closing and shall remain effective until eighteen
(18) months following the Closing (the “Survival Date”). After the expiration of such period, such representations and warranties and the provisions of this Section 9.1(a) shall expire and be of no further force and effect
except to the extent that a claim or claims shall have been asserted by ICF or the Shareholder, as the case may be, with respect thereto on or before the expiration of such period, provided however that the following representations and warranties
(collectively the “Surviving Representations”) shall survive the Survival Date until the date specified below. 
 (i)
Claims for indemnification based on breaches of representations and warranties of the Shareholder in Section 3.11 (Title to Shares) shall survive the Survival Date and claims for indemnification based on breaches of such representations and
warranties may be made at any time following the Closing. 
 (ii) Claims for indemnification based on breaches of representations and
warranties of the Shareholder in Sections 3.21 (Compliance with Laws), 3.22 (Environmental Matters), 3.24 (Absence of Certain Business Practices), 3.28 (ERISA), 3.29 (Tax Matters) pursuant to Section 9.2(b)(i)(C) shall survive the Survival Date
and claims for indemnification based on breaches of such representations and warranties may be made up to the date that is three (3) months after the expiration of the applicable statute of limitations. 
 (iii) Claims for indemnification based on breaches of representations and warranties of the Shareholder in Section 3.18 (Federal and State
Government Contracts) with respect to cost reimbursable Government Contracts shall survive the Survival Date and claims based on breaches of such representations and warranties may be made up to the date thirty (30) days after the applicable
Governmental Authority has agreed on final indirect cost rates for any fiscal year that began prior to the Closing. 
 (b) The undersigned
acknowledge and agree that the covenants contained in this Agreement, including, but not limited to the covenants contained in ARTICLE V above shall survive Closing and are unaffected by this Section 9.1. 
  

 71 

 (c) Any claim for indemnification under Sections 9.2(a)(i)(A) or 9.2(b)(i)(A) after the expiration of the
applicable survival period above, shall be null and void. 
 9.2 Indemnification. 
 (a) By ICF. 
 (i) Subject to
Section 9.2(g), following Closing, ICF shall protect, defend, indemnify and hold harmless the Shareholder, the Founders and their respective agents, representatives, successors, assigns, estates and heirs (“Shareholder
Indemnitees”) from and against any losses, damages and expenses (including, without limitation, except as provided in Section 9.2(d), reasonable counsel fees, costs and expenses incurred in investigating and defending against the
assertion of such liabilities) (collectively, “Losses”) that may be sustained, suffered or incurred by the Shareholder Indemnitees, and that are related to (A) any breach by ICF of its representations and warranties in this
Agreement, (B) any breach by ICF of its covenants, agreements or obligations in or under this Agreement, including payments of the purchase price for the Shares, (C) Taxes as provided in paragraph (ii) of this Section 9.2(a) or
(D) any liabilities of Caliber or the Acquired Subsidiaries following the Closing other than those liabilities for which the Shareholder and/or Founders have agreed to indemnify ICF pursuant to Section 9.2(b) of this Agreement. 

(ii) The obligations of ICF under paragraph (i) of this Section 9.2(a) shall extend to (A) all Taxes with respect to taxable periods
beginning after the Closing Date (including any Taxes with respect to transactions properly treated as occurring on the day after the Closing Date pursuant to Treasury Regulations Section 1.1502-76(b)(1)(ii)(B) or any similar provision of
state, local or foreign law) and (B) all Taxes with respect to Straddle Periods to the extent that such Taxes are allocable to the period after Closing pursuant to Section 5.11(b) or to the extent such Taxes are allocable to the period
ending on or prior to the Closing Date and have been accrued or otherwise reserved for on the Closing Balance Sheet. 
 (b) By the
Shareholder and the Founders. 
 (i) Subject to Sections 9.2(e), 9.2(f), 9.2(h), 9.2(i) and 9.3, following Closing, the Shareholder and
the Founders jointly and severally shall protect, defend, indemnify and hold harmless ICF, Caliber, the Acquired Subsidiaries and their respective Affiliates, and their officers, directors, employees, agents, representatives, successors and assigns
(“ICF Indemnitees”) from and against any Losses that may be sustained, suffered or incurred by ICF Indemnitees and that are related to (A) any breach by the Shareholder, Caliber or the Founders of their respective
representations and warranties in this Agreement, (B) any breach by the Shareholder or Caliber or the Founders of covenants and obligations in or under this Agreement, including, but not limited to the Shareholder’s obligations to make
payments to ICF pursuant to Section 2.3(e) and the Shareholder’s, Caliber’s or the Founders’ obligations pursuant to Article V (including but not limited to Shareholder’s obligations under Sections 5.8 and 5.9 and
obligations to make payments to ICF pursuant to Section 5.11(a) and 5.11(b)), (C) Taxes as provided in paragraph (ii) of this Section 9.2(b), to the extent such Taxes have not been accrued or otherwise reserved for on the Closing
Balance Sheet) and (D) the Transaction Costs incurred by the Shareholder, Caliber or the Founders (excluding the Scheduled Transaction Costs), it 
  

 72 

 being the intent of the parties that all of the provisions of this Agreement shall be interpreted to avoid requiring the
Shareholder or the Founders to pay (or receive a reduction in purchase price) twice for the same item. 
 (ii) The obligations of the
Shareholder and the Founders under paragraph (i) of this Section 9.2(b) shall extend to (A) all Taxes with respect to taxable periods ending on or prior to the Closing Date and (B) all Taxes with respect to Straddle Periods to
the extent that such Taxes are allocable to the period prior to Closing pursuant to Section 5.11(b) to the extent such Taxes have not been accrued or otherwise reserved for on the Closing Balance Sheet. Such obligations shall be without regard
to whether there was any breach of any representation or warranty under Article III with respect to such Tax or any disclosures that may have been made with respect to Article III or otherwise. The indemnification obligations under this paragraph
(ii) shall apply even if the additional Tax liability results from the filing of a return or amended return with respect to a pre-Closing Date transaction or period (or portion of a period) by ICF. ICF shall not cause or permit Caliber or any
Acquired Subsidiary to file an amended Tax Return with respect to any taxable period ending on or prior to the Closing Date or any Straddle Period unless (y) the Shareholder’s Representative consents in its sole discretion or (z) ICF
obtains an unqualified legal opinion in form and substance reasonably acceptable to the Shareholder’s Representative from counsel reasonably acceptable to the Shareholder’s Representative that such amendment is legally required to be filed
(provided, further, that such legal opinion may not assume any facts that are disputed in good faith by the Shareholder’s Representative). In the event of any conflict between the provisions of this Section 9.2(b)(ii) and any other
provision of this Agreement, the provisions of this Section shall control. 
 (c) Procedure for Third-Party Claims. 
 (i) If any Third-Party Claims shall be commenced, or any claim or demand shall be asserted (other than audits or contests with Taxing Authorities
relating to Taxes), in respect of which the Indemnified Party proposes to demand indemnification by Indemnifying Party under Sections 9.2(a) or 9.2(b), the Indemnified Party shall notify the Indemnifying Party in writing of such demand and the
Indemnifying Party shall have the right to assume the entire control of the defense, compromise or settlement thereof (including the selection of counsel), subject to the right of the Indemnified Party to participate (with counsel of its choice),
but the fees and expenses of such additional counsel shall be at the expense of the Indemnified Party. The Indemnifying Party will not compromise or settle any such action, suit, proceeding, claim or demand (other than, after consultation with
Indemnified Party, an action, suit, proceeding, claim or demand to be settled by the payment of money damages and/or the granting of releases, provided that no such settlement or release shall acknowledge the Indemnified Party’s
liability or obligate ICF with respect to activities of Caliber) without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld or delayed. 
 (ii) Notwithstanding anything to the contrary contained in this Section 9.2(c), ICF shall have the sole right to control and make all decisions
regarding interests in any Tax audit or administrative or court proceeding relating to Taxes, including selection of counsel and selection of a forum for such contest, provided, however, that in the event such audit or proceeding relates to
Taxes for which the Shareholder and/or the Founders are responsible and have agreed to indemnify ICF, (A) ICF, Caliber, the Shareholder, and the Founders shall 
  

 73 

 cooperate in the conduct of any audit or proceeding relating to such period, (B) the Shareholder, and the Founders
acting through the Shareholder’s Representative, shall have the right (but not the obligation) to materially participate in such audit or proceeding at the Shareholder’s and/or the Founders’ expense, (C) ICF shall not enter into
any agreement with the relevant taxing authority pertaining to such Taxes without the written consent of the Shareholder’s Representative, which consent shall not unreasonably be withheld, and (D) ICF may, without the written consent of
the Shareholder or the Founders, enter into such an agreement provided that ICF shall have agreed in writing to accept responsibility and liability for the payment of such Taxes and to forego any indemnification under this Agreement with respect to
such Taxes. 
 (iii) The parties will keep each other informed as to matters related to any audit or judicial or administrative proceedings
involving Taxes for which indemnification may be sought hereunder, including, without limitation, any settlement negotiations. Refunds of Tax relating to periods ending prior to the Closing Date (or to that portion of a Straddle Period that is prior
to Closing under the principles of Section 5.11(b)) shall be the property of the Shareholder, but only to the extent that such refunds are not attributable to (A) net operating loss or other carrybacks from periods ending after the Closing
Date, or (B) refund claims that are initiated by ICF (provided that ICF gives the Shareholder’s Representative prior notice of such possible claim and the Shareholder and the Founders decline to pursue such refund at its or their
own expense); provided, however, that ICF shall in no event have an obligation to file or cause to be filed a claim for refund with respect to any Taxes relating to any period. All other refunds of Tax are the property of ICF. 
 (iv) Any indemnity payment or payment of Tax by the Shareholder or the Founders or its or their Affiliates as a result of any audit or contest shall be
reduced by the present value of the correlative amount, if any, by which any Tax of ICF or its Affiliates is or will be reduced for periods ending after the Closing Date as a result thereof. (computed at the highest effective marginal tax rates at
which ICF is then paying Taxes and limited to the extent that the Tax Benefits can be utilized by ICF. 
 (v) The Indemnified Party shall
cooperate fully in all respects with the Indemnifying Party in any defense, compromise or settlement, subject to this Section 9.2(c) including, without limitation, by making available all pertinent books, records and other information and
personnel under its control to the Indemnifying Party. 
 (d) Procedure for Direct Claims. 
 (i) Any Direct Claim shall be asserted by written notice given by the Indemnified Party to the Indemnifying Party (each a “Direct Claim
Notice”). The Indemnifying Party shall have a period of twenty (20) Business Days from the date of receipt (the “Direct Claim Notice Period”) within which to respond to a Direct Claim Notice. If the Indemnifying Party
does not respond in writing within the Direct Claim Notice Period, then the Indemnifying Party shall be deemed to have accepted responsibility for the claimed indemnification and shall have no further right to contest the validity of that claim. If
the Indemnifying Party does respond in writing within the Direct Claim Notice Period, and rejects the claim in whole or in part, the Indemnified Party shall be free to pursue all remedies under Section 11.11. To the extent that any ICF
Indemnitees prevail in a Direct Claim (or the Shareholder’s Representative concedes (on 
  

 74 

 behalf of the Shareholder and/or the Founders), or otherwise does not timely respond to a Direct Claim Notice made by
ICF) then the Direct Claim shall be satisfied from the General Indemnity Escrow (and the Escrow Agent shall pay to ICF from the General Indemnity Escrow the amount of the Direct Claim) with no further action required by the Shareholder, the
Shareholder’s Representative, or the Founders. In the event that a Direct Claim is in excess of the General Indemnity Escrow, the Founders (but not the Shareholder) shall be and remain jointly and severally liable for any or all of such excess,
subject to the limitations of this Article IX, including, without limitation, Sections 9.2(e) and 9.2(f). 
 (ii) Costs Related to Direct
Claims. Notwithstanding anything in this Section 9.2 to the contrary, except as otherwise may be ordered by a court of competent jurisdiction, the Shareholder Indemnitees and ICF Indemnitees shall each bear their own costs, including
counsel fees and expenses, incurred in connection with Direct Claims against ICF and the Shareholder and the Founders, respectively, hereunder that are not based upon claims asserted by third parties. 
 (e) Calculation of Amount of Claims and Losses. The amount of any claims or losses subject to indemnification under Section 9.2(b) shall be
calculated net of any amounts recovered by ICF or its Affiliates (including Caliber after the Closing) under applicable insurance policies held by ICF or its Affiliates, and ICF agrees to make or cause to be made all reasonable claims for insurance
under such policies that may be applicable to the matter giving rise to the indemnification claim hereunder. The amount of any claims or losses subject to indemnification under Section 9.2(b) shall be calculated net of the present value of any
Tax benefits to ICF or its Affiliates (including Caliber and the Acquired Subsidiaries after the Closing) resulting from the matter giving rise to the indemnification claim hereunder (computed at the highest effective marginal tax rates at which ICF
is then paying Taxes and limited to the extent that the Tax Benefits can be utilized by ICF). 
 (f) Limitations on Rights of ICF
Indemnitees. 
 (i) Rights of ICF Indemnitees to indemnification by the Shareholder and the Founders under Section 9.2(b)(i)(A)
shall be subject to the limitations that ICF Indemnitees shall not be entitled to indemnification with respect to a claim or claims made thereunder unless the aggregate amount of all such claims exceeds $150,000, in which event the indemnity
provided for in Section 9.2(b)(i)(A) shall be effective with respect to the total amount of such damages in excess of the first $150,000. Notwithstanding the foregoing, the $150,000 limitation shall not apply to an indemnification claim made
under (A) Section 9.2(b)(i)(A) based on the breach of the representations or warranties in Section 3.11 (Title to Shares) or (B) Section 3.29 (Taxes). 
 (ii) Notwithstanding anything to the contrary contained in this Agreement, the Shareholder’s maximum liability to ICF Indemnitees under this Section 9.2 shall be limited exclusively to and shall not exceed
the General Indemnity Escrow, and ICF Indemnitees’ sole recourse against the Shareholder shall be the General Indemnity Escrow. 
 (iii) Except as otherwise provided in this Section 9.2(f)(iii), the Founders’ aggregate maximum liability to ICF Indemnitees under this Section 9.2 shall be 
  

 75 

 limited exclusively to and shall not exceed the General Indemnity Escrow, and ICF Indemnitees’ recourse against the
Founders shall be limited to the General Indemnity Escrow. Notwithstanding the foregoing, the Founders shall be jointly and severally liable to the ICF Indemnitees’ for claims (A) made under Section 9.2(b)(i)(A) based on the breach of
the representations and warranties in Section 3.11 (Title to Shares), Section 3.28 (ERISA) and Section 3.29 (Taxes); (B) made under clauses (B), (C) or (D) of Section 9.2(b)(i); and (C) based on fraud,
intentional misrepresentation or criminal acts on the part of the Shareholder, Caliber, the Acquired Subsidiaries and their respective officers, directors, agents, representatives and trustees. 
 (g) Limitations on Rights of Shareholder Indemnitees. Rights of Shareholder Indemnitees to indemnification by ICF under Section 9.2(a)(i)(A)
shall be subject to the limitation that Shareholder Indemnitees shall not be entitled to indemnification with respect to a claim or claims made thereunder unless the aggregate of damages with respect to all such claims exceeds $50,000, in which
event the indemnity provided for in Section 9.2(a)(i)(A) shall be effective with respect to the amount of such damages which exceeds $50,000; provided however that ICF’s maximum liability to the Shareholder Indemnitees under
Section 9.2(a)(i)(A) shall not exceed $1,500,000. The aforementioned limitations in this paragraph shall not apply to the indemnification liabilities of ICF with respect to claims based on fraud, intentional misrepresentations, or criminal acts
on the part of ICF 
 (h) Limitation on Rights of Shareholder and Founders. Notwithstanding anything to the contrary, the Shareholder
and the Founders each acknowledge and agree that they shall have no right to make a claim against Caliber or any Acquired Subsidiaries pursuant to any indemnity provision or agreement or otherwise in respect of Claims of ICF Indemnitees pursuant to
Section 9.2(b). 
 (i) Limitations on Remedies. No party hereto shall be liable to the other for indirect, special, incidental,
consequential or punitive damages claimed by such other party resulting from such first party’s breach of its obligations, agreements, representations or warranties hereunder, provided that nothing hereunder shall preclude any recovery by an
Indemnitee against an Indemnitor for third party claims. 
 9.3 Escrow Account; Withholding of Earn Out and Re-Award Escrows.

 Pursuant to Section 2 and the General Indemnity Escrow Agreement, at the Closing, ICF shall deliver to the Escrow Agent the General
Indemnity Escrow Deposit and the Escrow Agent shall set up an escrow account pursuant to the terms of the General Indemnity Escrow Agreement to secure the Shareholder’s indemnification obligations under this Article IX. Within thirty
(30) days following the expiration of the Survival Date, the Escrow Agent will cause any amounts remaining in the General Indemnity Escrow (less any amount which has been or shall be offset or is subject to a pending dispute and interest
thereon) to be delivered to the Shareholder. 
  

 76 

 9.4 Effect of Investigation. 
 The right to indemnification or other remedies based on any representation, warranty, covenant or obligation of the Shareholder, Caliber or the Founders
contained in or made pursuant to this Agreement or the Transaction Documents shall not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the
execution and delivery of this Agreement or the Closing Date occurs, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or obligation. The waiver of any condition to the obligation of ICF to
consummate the Contemplated Transactions, where such condition is based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, shall not affect the right to indemnification or other
remedies based on such representation, warranty, covenant or obligation. 
 ARTICLE X

 10.1
Termination. 
 This Agreement may be terminated and the transactions contemplated hereby may be abandoned: 
 (a) at any time, by mutual written agreement of the Shareholder and ICF; 
 (b) at any time after October 3, 2005 by either the Shareholder or ICF upon five business days’ prior written notice to the other party, if the Closing shall not have occurred for any reason other than a
breach of this Agreement by the terminating party; 
 (c) by ICF, if there has been a material violation or breach by the Shareholder of any
agreement, representation or warranty contained in the Agreement, that has rendered the satisfaction of any condition to the obligations of ICF impossible and such violation or breach has not been waived by ICF; 
 (d) by the Shareholder, if there has been a material violation or breach by ICF of any agreement, representation or warranty contained in the Agreement,
that has rendered the satisfaction of any condition to the obligations of the Shareholder impossible and such violation or breach has not been waived by the Shareholder; 
 (e) by either ICF or the Shareholder if a court of competent jurisdiction shall have issued an order permanently restraining or prohibiting the transactions contemplated by the Agreement, and such order shall have
become final and nonappealable; 
 (f) by ICF, at any time prior to Closing Date, if ICF is not reasonably satisfied in good faith
with the results of its discussions with the top eight (8) customers of Caliber and the Acquired Subsidiaries; or 
 (g) by the
Shareholder, at any time prior to the Closing Date, if the Shareholder is unable to satisfy Section 7.14 (Fairness Opinion) upon its good faith best efforts. 
  

 77 

 10.2 Procedure and Effect of Termination. 
 In the event of the termination of this Agreement and the abandonment of the transactions contemplated hereby, written notice thereof shall be given by a
terminating party to the other parties and this Agreement shall terminate and the transactions contemplated hereby shall be abandoned without further action by the Shareholder or ICF. If this Agreement is terminated pursuant to Section 10.1:

 (a) ICF shall upon written request from the Shareholder return all documents, work papers and other materials (and all copies thereof)

Caliber shall be treated in accordance with Section 5.2 and the Confidentiality Agreement referred to in such Section;

option of the Shareholder, all filings, applications and other submissions made pursuant to Sections 5.3 and 5.4 shall, to the extent practicable, be withdrawn from the agency or other Person to which made;

of this Agreement; and

any party from liability for willful breach of this Agreement.

shall in all respects be governed by, and construed in accordance with, the laws (excluding conflict of laws rules and principles) of the Commonwealth of Virginia applicable to agreements made and to be performed entirely within the Commonwealth of
Virginia, including all matters of construction, validity and performance. 
 11.4 Entire Agreement. 
 This Agreement, together with the Exhibits and Schedules hereto and the other Transaction Documents, constitutes the entire agreement of the parties
relating to the subject matter hereof and supersedes all prior contracts or agreements, whether oral or written. There are no representations, agreements, arrangements or understandings, oral or written, between or among the parties relating to the

 80 

 11.5 Severability. 
 Should any provision of this Agreement or the application thereof to any person or circumstance be held invalid or unenforceable to any extent: (a) such provision shall be ineffective to the extent, and only to
the extent, of such unenforceability or prohibition and shall be enforced to the greatest extent permitted by Law; (b) such unenforceability or prohibition in any jurisdiction shall not invalidate or render unenforceable such provision as

 11.6 Amendment. 
 Neither this

shall be sought. 
 11.7 Effect of Waiver or Consent. 
 No waiver or consent, express or implied, by any person to or of any breach or default by any party in the performance by such party of its obligations hereunder shall be deemed or construed to be a consent or waiver
to or of any other breach or default in the performance by such party of the same or any other obligations of such party hereunder. No single or partial exercise of any right or power, or any abandonment or discontinuance of steps to enforce any
right or power, shall preclude any other or further exercise thereof or the exercise of any other right or power. Failure on the part of a party to complain of any act of any party or to declare any party in default, irrespective of how long such
failure continues, shall not constitute a waiver by such person of its rights hereunder until the applicable statute of limitation period has run.

 Indemnification under Article IX shall constitute the sole remedy for Losses
identifiable pursuant to Sections 9.2(a)(i) or 9.2(b)(i), except with respect to fraud or intentional misconduct by a party and except where other remedies are expressly provided herein, in which case such other remedies and indemnification under
Article IX shall be cumulative, and the use of any one such right or remedy by any party shall not preclude or waive the right to use any or all other such remedies.

binding upon, and inure to the benefit of, the parties hereto and their respective legal representatives, successors and assigns. Nothing in this Agreement, whether express or implied, shall be construed to give any person (other than the parties
hereto and their respective legal representatives, successors and assigns and as expressly provided herein, and to the extent provided in Article IX, the Indemnified Parties) any legal or equitable right, remedy or claim under or in respect of this
Agreement or any covenants, conditions or provisions contained herein, as a third party beneficiary or otherwise. 
  

 81 

 11.10 Assignability. 
 This Agreement shall not be assigned by any party hereto without the prior written consent of the other party hereto, provided, however, that the prior written consent of the Shareholder’s Representative
shall not be required with respect to (a) any assignment by ICF of its rights and obligations under this Agreement to an Affiliate of ICF so long as such assignment does not relieve ICF of its obligations hereunder; or (b) any collateral
assignment of ICF’s rights and remedies under this Agreement to any lender under credit and collateral agreements, as such agreements may be amended, modified or replaced from time to time, so long as such lender does not have the right to
exercise any of ICF’s rights and remedies under this Agreement in the absence a default by ICF under the applicable credit and collateral documents. The Shareholder and the Founder hereby agree to execute and deliver (and authorize the
Shareholder’s Representative to execute and deliver) such documents, instruments and agreements as such lender may reasonably require to confirm, reaffirm or perfect such collateral assignment. This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto and their respective successors and permitted assigns. 
 11.11 Dispute Resolution and
Arbitration. 
 In the event that any dispute arises among the parties pertaining to the subject matter of this Agreement, and the

delay). The Dispute Notice shall be accompanied by (i) a statement of the Claimant describing the dispute in reasonable detail and (ii) documentation, if any, supporting the Claimant’s position on the dispute. Within twenty
(20) days after the other party’s (“Respondent”) receipt of the Dispute Notice and accompanying materials, the parties shall submit the dispute to mediation in the Washington, D.C. area under the rules of the American

arbitration in confidence.
