(a) Seller and Buyer shall cooperate and provide each other access to their respective books, records and employees as are reasonably requested in connection with the matters addressed in this Section 2.6. Attached hereto as Schedule 2.6 is a reasonable estimate, as of the date of this Agreement, of the Net Working Capital. Promptly after conclusion of United Holdings’ year end audit, or if sooner, the fifth Business Day preceding Closing, Seller shall calculate the Net Working Capital and shall provide Buyer with written notice thereof. Within five Business Days prior to the expected Closing Date, Seller shall in good faith estimate Net Working Capital as of as of the close of business on the Business Day immediately preceding the Closing Date and shall provide Buyer with written notice thereof and of the Estimated Working Capital Adjustment. The existence of any dispute with respect to any such calculations shall not delay or otherwise affect the Closing or the obligation to make the payments specified in Section 2.5 at the Closing. For purposes of calculating Net Working Capital, all payments made at Closing pursuant to Section 5.6 shall be deemed to have been paid as of as of the close of business on the Business Day immediately preceding the Closing Date.

(b) Within 45 days after Closing, Buyer shall provide Seller with its good faith calculation of Net Working Capital as of the close of business on the Business Day immediately preceding the Closing Date and the Working Capital Adjustment, as well as detailed supporting information, which clearly delineates the specific line item differences between Buyer’s new calculation and Seller’s previous calculation. If Seller disagrees with any of the calculations provided by Buyer pursuant to the notice referenced in the foregoing sentence, then it shall provide Buyer with written notice thereof within 30 days after receiving written notice

thereof and shall include reasonable detail regarding such specific objections. If Buyer and Seller working in good faith are unable to agree on such disputed items on or prior to the 90^th day following the Closing Date, then either Party may refer such dispute to Ernst & Young LLP or, if that firm declines to act as provided in this Section 2.6(b), another firm of independent public accountants, mutually acceptable to Buyer and Seller (such selected firm being the “Accounting Firm”), which firm shall make a final and binding determination as to all matters in dispute on a timely basis and promptly shall notify the Parties in writing of its resolution. Such Accounting Firm handling the dispute resolution shall act as an expert and not as a moderator and shall not have the power to modify or amend any term or provision of this Agreement. Each of Buyer and Seller shall bear and pay one-half of the fees and other costs charged by such Accounting Firm. If Seller does not object to Buyer’s calculations within the time period and in the manner set forth in the second sentence of this Section 2.6(b) or accepts Buyer’s calculations, then such calculations as set forth in Buyer’s notice shall become final and binding upon the Parties for all purposes hereunder.

(c) If the Working Capital Adjustment (as agreed between Buyer and Seller or as determined by the above-referenced accounting firm or otherwise) is (i) greater than the Estimated Working Capital Adjustment as paid by Buyer at Closing, then Buyer shall pay to Seller within five Business Days after such amounts are so agreed or determined, by wire transfer of immediately available funds to an account or accounts designated by Seller, the amount of such difference or (ii) less than the Estimated Working Capital Adjustment as paid by Buyer at Closing, then Seller and Buyer shall execute a joint instruction to the Working Capital Escrow Agent to pay to Buyer, within five Business Days after such amounts are agreed or determined, by wire transfer of immediately available funds to an account designated by Buyer, the amount of such difference.

2.7 Earnout. Subject to Section 9.12, Buyer will pay the Earnout Amount, if any, in accordance with Exhibit D.

2.8 Purchase Price Allocation.

(a) Seller and Buyer agree that the Base Purchase Price shall be allocated among the Companies for Tax purposes in accordance with the allocation as agreed by the Seller and Buyer prior to the Closing Date (the “Base Purchase Price Allocation”).

(b) Within 30 days after the Net Working Capital is agreed or determined in accordance with Section 2.6, Seller shall provide to Buyer a proposed allocation (consistent with the Base Purchase Price Allocation) of the Purchase Price among the Companies and a further allocation, to the extent consistent with Treasury Regulation Sections 1.338-6, 1.755-1 and 1.1060-1, of the Purchase Price among the Assets of the Companies (the “Purchase Price Allocation Schedule”). Within 30 days after its receipt of Seller’s proposed Purchase Price Allocation Schedule, Buyer shall propose to Seller any changes thereto or otherwise shall be deemed to have agreed thereto. In the event that Buyer proposes changes to Seller’s proposed Purchase Price Allocation Schedule within the 30 day period described above, Seller shall, in good faith, consider any comments so received from Buyer and shall furnish Buyer with a revised Purchase Price Allocation Schedule as soon as practicable. If after receipt of the revised Purchase Price Allocation Schedule, Buyer disagrees with the allocation of the Purchase Price among the Assets of the Companies set forth therein, then the Accounting Firm shall determine such allocation. The cost of such Accounting Firm shall be borne equally by Seller and Buyer.

(c) The Purchase Price Allocation Schedule shall be revised to take into account subsequent adjustments to the Purchase Price, including any indemnification payments (which shall be treated for Tax purposes as adjustments to the Purchase Price), in accordance with the provisions of Section 1060 of the Code and the Treasury Regulations thereunder. Each of Seller and Buyer agree to file all applicable Tax Returns and otherwise report their affairs for Tax purposes consistent with the Purchase Price Allocation Schedule, as agreed to by Buyer and Seller or as determined by the Accounting Firm, except as otherwise required by applicable Laws.

obtained a favorable determination letter (or opinion letter, if applicable) as to its qualified status under the Code and, to the Seller’s Knowledge, no condition exists that could be reasonably expected to result in the revocation of any such letter. Each Benefit Plan that is a “non-qualified deferred compensation plan” (as defined under Section 409A(d)(1) of the Code) has been operated and administered in compliance with Section 409A of the Code since January 1, 2005 or the date it was established, if later.

(c) All premiums required to be paid, all benefits, expenses and other amounts due and payable, and all contributions, transfers, or payments required to be made to or under the Benefit Plans will have been paid, made, or accrued and are reflected in the most recent Financial Statements for all services on or prior to the Balance Sheet Date.

(e) No Benefit Plan is or has ever been a “multiemployer plan” as defined in Sections 3(37) and 4001(a)(3) of ERISA nor has any of the Companies or any ERISA Affiliate contributed to, or had an obligation to contribute to, within six years prior to the Closing Date, any “multiemployer plan” as defined in Sections 3(37) and 4001(a)(3) of ERISA.

(f) No Benefit Plan provides, or reflects or represents any liability of Sellers or the Companies to provide, retiree life insurance, retiree health or other retiree employee welfare benefits to any person for any reason, except as may be required by the Consolidated Omnibus Budget Reconciliation Act of 1986 (“COBRA”) or other applicable Laws. Sellers have never represented, promised or contracted (whether in oral or written form) to provide retiree life insurance, retiree health or other retiree employee welfare benefit to any Person, except to the extent required by COBRA or similar provisions of applicable Laws.

(g) No event has occurred and no condition exists with respect to the Benefit Plans that could subject any of the Companies, any Benefit Plan, or the Buyer to any Tax, fine, penalty or Liability under applicable Laws. Other than routine claims for benefits, there are no proceedings pending against a Benefit Plan or against the assets of a Benefit Plan, and to the Knowledge of Sellers, (i) no such proceeding has been threatened orally or in writing, and (ii) no event has occurred and no circumstances exist that may give rise to or serve as a basis for the commencement of any such proceeding.

(h) Neither the execution and delivery of this Agreement, nor the consummation of the transactions contemplated hereby will;

(i) result in any payment to be made by any of the Companies, including severance, unemployment compensation, golden parachute (as defined in Section 280(g) of the Code) or otherwise, becoming due to any employee, director or consultant of the Companies, or

Each such registration or issuance is valid and subsisting and is not subject to any outstanding order. No Claim or Proceeding is pending or, to Seller’s Knowledge, threatened, which challenges the legality, validity, enforceability, use or ownership of such item. The Companies own, free and clear of any Liens (other than Permitted Liens), or has the license or right to use, all material Intellectual Property currently used or necessary to conduct its business as presently conducted. Except as set forth on Schedule 3.22, no Company has granted any license or any rights in any material Intellectual Property to any Person.

Except as set forth on Schedule 3.23 and except for ordinary compensation paid or payable in the ordinary course of business and consistent with past practices to senior management (and phantom equity obligations owing to employees), no Company is owed any amount from, owes any amount to, guarantees any amount owed by, has any Contracts with or has any commitments to any other Company, Affiliate, officer or director of a Company or any member of a family group of any of the foregoing; provided, however, that the foregoing does not include amounts owed by United Holdings to any of its Subsidiaries or amounts owed by any of the Subsidiaries to United Holdings or another Subsidiary.

(a) Each of Seller and Buyer shall (and each shall cause its respective applicable Affiliates to) use commercially reasonable efforts to obtain as promptly as practicable all Seller Approvals and Company Consents applicable to such Person, and all other material consents and approvals that any of Seller, Buyer or their respective Affiliates are required to obtain in order for such Person to consummate the transactions contemplated hereby; provided that for purposes of clarification, the obtaining of such consents and approvals shall not be a condition to Closing except to the extent expressly set forth in Section 6.5 or Section 7.5, as applicable.

Except as required or permitted hereby, or as consented to by Buyer (which consent shall not be unreasonably withheld, conditioned or delayed), or as otherwise set forth in Schedule 5.3, during the Interim Period, Seller will cause the Companies to operate in the ordinary course of business. Without limiting the foregoing, except as otherwise required or permitted hereby or required by the terms of any permit or any Material Contract or as consented to by Buyer, which consent shall not be unreasonably withheld, conditioned or delayed (except that none of this Section 5.3 shall apply to Contracts for which neither a Company nor any of the Assets of the Companies will be bound or have liability after Closing, or services terminated pursuant to Section 5.5), Seller will cause the Companies not to undertake any of the following without the consent of Buyer (which consent shall not be unreasonably withheld, conditioned or delayed):

employee of any Company, whether on or after Closing, as a result of the transactions contemplated by this Agreement, or as a result of any decision or event after the Closing, Buyer shall be solely responsible for such WARN Obligation.

(b) During the period from the date of this Agreement to the Closing Date, except as otherwise permitted under this Agreement, the Companies will not enter into any additional Contracts with employees, directors or consultants of the Companies that will create any obligation to Buyer or the Companies after the Closing Date, or make or agree to make any material changes to any existing Contracts or agreements with employees, directors or consultants of the Companies without Buyer’s prior written consent; provided, however, that the foregoing shall not prohibit increases in compensation to employees in the ordinary course of business consistent with past practices.

5.5 Resignation and Removal. Notwithstanding anything in this Agreement to the contrary, at or prior to the Closing, Seller may (though it need not do so, except as provided in Section 2.4(c)) cause or accept the resignation or removal of any manager, partner, officer and/or director, as applicable, nominated or appointed by Seller or its Affiliates to any board or operating, management or other committee relating to the Assets of the Companies established under the Companies’ Charter Documents.

5.7 Tax Matters.

(a) With respect to any Tax Return that is required to be filed by a Company after the Closing Date with respect to a Pre-Closing Period, Seller shall prepare or cause to be prepared such Tax Return. With respect to any Tax Return that is required to be filed by a Company after the Closing Date with respect to a Straddle Period, Buyer shall prepare or cause to be prepared such Tax Return. Not later than 30 days prior to the due date (including extensions) of each Tax Return for a Pre-Closing Period or for a Straddle Period, the Party responsible for preparing such Tax Return shall deliver a copy of such Tax Return to the other Party for its review and reasonable comment. The Party responsible for preparing such Tax Return shall

consider in good faith any such comments received from the other Party not less than 15 days prior to the due date (including extensions) for filing such Tax Return and shall deliver a final copy of such Tax Return to such other Party not less than ten days prior to such due date. Buyer shall cause each such Tax Return to be timely filed and shall timely pay the Taxes shown due thereon. Such Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Laws. For the avoidance of doubt, Seller shall have sole responsibility for any consolidated, combined or unitary Tax Returns that Seller (or one of its Affiliates other than a Company) is obligated to file and that include any of the Companies for a taxable period that includes the Closing Date, and such Tax Returns shall not be subject to the procedures described in this Section 5.7.

(b) In the case of Taxes of any Company with respect to any Straddle Period, the portion of any such Tax that is attributable to the portion of the period ending on the Closing Date shall be:

(ii) in the case of any liability for any real property, personal property, ad valorem and similar Taxes and Taxes that are otherwise imposed on a periodic basis with respect to the assets of any of the Companies, deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period), multiplied by a fraction, the numerator of which is the number of calendar days in the portion of the period ending on the Closing Date and the denominator of which is the number of calendar days in the entire period; and

(iii) For purposes of the Texas franchise Tax, (A) the entire amount of the Texas franchise Tax imposed on the Companies for any privilege period beginning before January 1, 2012, whether based on taxable capital, earned surplus, or taxable margin, and (B) for the privilege period beginning on or after January 1, 2012, the amount that would be owed if the Companies filed, as a combined group, a final franchise tax report in accordance with Section 171.0011 of the Texas franchise Tax that is based on the business activity of the Companies computed on the period beginning on the day after the last day for which a Texas franchise Tax was computed on a previous report under Chapter 171 of the Texas franchise Tax that included the Companies and ending on the Closing Date.

(c) After Closing, Buyer shall grant or cause the Companies to grant to Seller (or its designees) access at all reasonable times to all of the records relating to the Companies (and to the employees of the Companies for explanation thereof), and shall afford Seller (or its

designees) the right (at Seller’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Seller (or its designees) to prepare Tax Returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund Claims and to conduct negotiations with Taxing Authorities.

(d) Unless required by applicable Laws, no amended Tax Return with respect to a Pre-Closing Period or Straddle Period shall be filed by or on behalf of any Company without the prior written consent of Seller if such amended Tax Return would increase the obligations of Seller pursuant to Article IX or decrease the amount owed to Seller pursuant to Section 5.7(e).

(e) The amount of any refunds of Taxes of the Companies for any Pre-Closing Period shall be for the account of Seller. The amount of any refunds of Taxes of the Companies for any Tax period beginning after the Closing Date shall be for the account of Buyer. The amount of any refund of Taxes of the Companies for any Straddle Period shall be equitably apportioned between Buyer and Seller in accordance with the principles set forth in Section 5.7(b). Each Party shall forward, and shall cause its Affiliates to forward, to the Party entitled to receive a refund of Tax pursuant to this Section 5.7(e) the amount of such refund within 30 days after such refund is received, net any costs or expenses incurred by such Party or its Affiliates in procuring such refund.

5.8 Public Announcements. The Parties will consult with each other prior to issuing any publication or press release of any nature with respect to this Agreement or the transactions contemplated hereby and shall not make or issue, or cause to be made or issued, any such publication or press release prior to such consultation and without the prior written consent of the other Party (which consent will not be unreasonably withheld or delayed) except to the extent, but only to such extent, that, in the opinion of the Party issuing such publication or press release, such announcement or statement may be required by Law, any listing agreement with any securities exchange or any securities exchange regulation, in which case the Party proposing to issue such publication or press release shall use its reasonable efforts to consult in good faith with the other Party before issuing any such publication or press release and shall reasonably cooperate with the other Party in good faith with respect to the timing, manner and content of disclosure.

5.9 Updating. From time to time prior to the Closing, Seller may at its option supplement or amend and deliver updates to the Schedules to complete or correct any information in such Schedules or in any representation or warranty in Article III with regard to events, circumstances or matters that arose or occurred after the date of this Agreement. Any such update made pursuant to this Section 5.9 shall be deemed to cure any inaccuracy of any representation or warranty made in this Agreement, provided that any such update shall be disregarded for purposes of the conditions to closing set forth in Article VI. Notwithstanding the foregoing, for purposes of the indemnity obligations of Seller in this Agreement, the Schedules shall be deemed to include all information contained in any supplement, amendment or update thereto.

5.10 Escrow Funds. The Buyer is entitled to all or a portion of the Working Capital Escrowed Cash to the extent of any obligations of the Seller under Section 2.6 and the Indemnity Escrowed Cash to the extent of any obligations of the Seller under Section 9.2. To the extent

funds are due to Buyer, Buyer and Seller shall jointly instruct the Working Capital Escrow Agent and the Indemnity Escrow Agent, respectively, to release such funds to Buyer that are specified with reasonable detail by the Seller. In the event there is a dispute regarding the amount of funds to be released from the Working Capital Escrow Account or the Indemnity Escrow Account, only that portion of the funds in dispute shall be held back and not released until resolution of the dispute. If any Indemnity Escrowed Cash (or interest thereon) remains in the Indemnity Escrow Account on April 15, 2012 and there is no indemnity Claim of the Buyer then still unresolved (or otherwise once all such Claims are resolved), the Parties shall execute and deliver to the Indemnity Escrow Agent joint written instructions promptly to deliver all such amounts by wire transfer of immediately available funds to Seller. If any Working Capital Escrowed Cash (or interest thereon) remains in the Working Capital Escrow Account on the date that such Working Capital Adjustment is resolved and there is no Working Capital Adjustment payable to Buyer, the Parties shall execute and deliver to the Working Capital Escrow Agent joint written instructions promptly to deliver all such amounts by wire transfer of immediately available funds to Seller.

5.11 Further Assurances. Subject to the terms and conditions of this Agreement, at any time or from time to time after the Closing, at either Party’s request and without further consideration, the other Party shall (and in the case of Buyer, Buyer shall and shall cause the applicable Companies to) execute and deliver to such Party such other instruments of sale, transfer, conveyance, assignment and confirmation, provide such materials and information and take such other actions as such Party may reasonably request in order to consummate the transactions contemplated by this Agreement. The Parties agree that they will use their respective commercially reasonable efforts to cause the Working Capital Escrow Agent and the Indemnity Escrow Agent, respectively, to return at the Closing a duly executed counterpart executed by each such Escrow Agent to the Working Capital Escrow Agreement and Indemnity Escrow Agreement, as applicable.

6.5 Consents and Approvals. HSR Approval and the Company Consents listed on Schedule 6.5 shall have been duly obtained, made or given and shall be in full force and effect; provided, however, that the absence of any appeals and the expiration of any appeal period with respect to any of the foregoing shall not constitute a condition to Closing hereunder.

6.7 Purchase Orders. The aggregate value of the orders for sale of goods or services by the Companies outstanding on the Closing Date shall be greater than $226,685,912; provided, however, that for purposes of determining such aggregate value on the Closing Date, such amount shall (a) be updated for new orders greater than $500,000 obtained and not revoked after the date hereof and (b) include the portion of any order listed on Schedule 3.19(a) or any such new order for the sale of goods or services by the Companies that has been fulfilled.

LIMITATIONS ON LIABILITY, WAIVERS AND ARBITRATION

9.1 Survival of Representations and Warranties. The representations and warranties of the Seller and Buyer set forth in this Agreement and the right of an indemnified Person to assert any Claim for indemnification related thereto shall survive the Closing until 5:00 p.m. on the one year anniversary of the Closing Date (the “Base Survival Period”), after which date and time no Claims for indemnification may be asserted, regardless of when such right arose; provided, however, that:

(a) the Excluded Representations and representations and warranties set forth in Sections 3.16 (Environmental Matters), 3.17 (Taxes), 3.21 (Employee Benefits) and 3.26 (Phantom Equity Plan) shall survive the Closing until the end of the Earnout Period;

(b) any Claim that was made prior to the expiration of the survival period specified herein for any representation, warranty, covenant, agreement, right or obligation that gave rise to such Claim shall survive until such Claim is finally paid or adjudicated.

9.2 Indemnification of Buyer by Seller. Subject to the limitations on recourse and recovery set forth in this Article IX, from and after the Closing, Seller shall indemnify, defend and hold harmless Buyer from and against any and all Losses imposed upon or incurred after the Closing by Buyer, any of the Companies, or any of their respective officers, managers, partners, directors, Affiliates, employees or agents in connection with, arising out of or resulting from:

(a) the inaccuracy or breach of any representation or warranty made by Seller in this Agreement or in any certificate, document or agreement delivered pursuant to Section 2.4;

(b) any nonfulfillment or breach by Seller of any covenant or agreement made by Seller under this Agreement or in any certificate, document or agreement delivered pursuant to Section 2.4; and

9.3 Indemnification of Seller by Buyer. Subject to the limitations on recourse and recovery set forth in this Article IX, from and after the Closing, Buyer shall indemnify, defend and hold harmless Seller from and against any and all Losses imposed upon or incurred after the Closing by Seller or any of its respective officers, managers, partners, directors, Affiliates, employees or agents in connection with, arising out of or resulting from:

(a) the inaccuracy or breach of any representation or warranty made by Buyer in this Agreement or in any certificate, document or agreement delivered pursuant to Section 2.5;

(b) any nonfulfillment or breach by Buyer of any covenant or agreement made by Buyer under this Agreement or in any certificate, document or agreement delivered pursuant to Section 2.5; and

(c) any and all liabilities of the Companies (except to the extent Seller as of such time has an indemnity obligation to Buyer with respect thereto).

9.4 Limitations.

(a) If any Claim for indemnification by Buyer or Seller relating to any single event or series of related events that are indemnifiable under Sections 9.2 and 9.3 results in aggregate Losses (subject to Section 9.3(a)) that do not exceed $50,000, then such Losses shall not be deemed to be Losses under this Agreement and shall not be eligible for indemnification under this Article IX.

(b) Buyer and Seller shall be entitled to be indemnified pursuant to Sections 9.2 and 9.3 for Losses (subject to Section 9.4(a)) only if and to the extent that the aggregate amount of all such Losses exceeds 1% of the Base Purchase Price (the “Deductible”), subject to the other limitations on recovery and recourse set forth in this Agreement.

(c) No indemnifying Person shall be liable for any Losses that are indemnifiable under Sections 9.2 or 9.3 unless a written demand for indemnification under this Agreement is delivered by the indemnified Person to the indemnifying Person with respect thereto prior to 5:00 p.m. on the final date pursuant to Section 9.1, if any, to assert a Claim for indemnification on the basis asserted in such written demand.

(d) Notwithstanding anything to contrary contained in this Agreement, to the extent Buyer is entitled to indemnification pursuant to Section 9.2, Buyer’s sole recourse shall be to the Indemnity Escrowed Cash; provided, however, that the Buyer may also have recourse by set-off against the Earnout Amount, if any, as provided in Section 9.12, with respect to (i) indemnification due to Buyer as a result of the inaccuracy or breach of the Excluded Representations, the representations and warranties set forth in Sections 3.16 (Environmental Matters), 3.17 (Taxes), 3.21 (Employee Benefits) and 3.26 (Phantom Equity Plan), and (ii) any amounts for which Buyer was entitled to indemnification from Seller under Section 9.2 and with respect to which a Claim was asserted prior to the expiration of the representation, warranty, covenant, or agreement under Section 9.1, but which was not fully paid from the Indemnity Escrow Cash.

(e) Notwithstanding anything to the contrary contained in this Agreement, under no circumstances shall any Party be entitled to double recovery under this Agreement, and to the extent a Party is compensated for a matter through the Working Capital Adjustment or insurance recovery, such Party shall not have a separate right to indemnification such matter.

(f) Notwithstanding anything to the contrary contained in this Agreement, the limitations imposed by Sections 9.4(a) or 9.4(b) shall not apply to indemnification Claims with respect to Excluded Representations, Seller Taxes or the Phantom Equity Plan.

(g) In the event that, following the Closing, Buyer or a Company actually recovers amounts from a third party (including an insurer) with respect to a Claim for which Buyer or the Company have already received an indemnification payment (either from the Indemnity Escrow Account or by set off against the Earnout Amount), then Buyer or such Company, as applicable, will promptly (i) return to the Indemnity Escrow Account the amount it received from it with respect to such Claim if the Base Survival Period has not expired at such time, (ii) credit to the Earnout Amount the amount set off with respect to such Claim if the

Earnout Amount has not been paid to the Seller at such time, and (iii) pay to the Seller the remaining amount it received or set off against Buyer’s obligation to pay the Earnout Amount with respect to such Claim.

(h) For the purpose of determining the amount or value of a Claim for which indemnification is available under this Article IX, any references or qualifications in the underlying representation, warranty, covenant, or agreement with respect to materiality (including Material Adverse Effect) shall be disregarded.

9.5 Claims Procedures.

(a) Promptly after receipt by any indemnified Person of notice of the commencement or assertion of any Claim or Proceeding by a third party or circumstances which, with the lapse of time, such indemnified Person believes is likely to give rise to a Claim or Proceeding by a third party or of facts causing any indemnified Person to believe it has a Claim for breach hereunder (an “Asserted Liability”), such indemnified Person shall give prompt written notice thereof (the “Claims Notice”) to the relevant indemnifying Person, provided that in any event, such indemnified Person shall give the Claims Notice to the indemnifying Person no later than the later of (i) 30 days after becoming aware of such Asserted Liability or (ii) 10 days after the filing of the next Quarterly Report on Form 10-Q or Annual Report on Form 10-K of Kirby Corporation that is filed after Buyer becomes aware of such Asserted Liability. The Claims Notice shall describe the Asserted Liability in reasonable detail, and shall indicate the amount (estimated, if necessary) of the Loss that has been or may be suffered. The indemnified Person and the indemnifying Person agree to keep each other reasonably appraised of any additional information concerning any Asserted Liability.

(b) As to an Asserted Liability arising from a third party action, the indemnifying Person shall be, subject to the limitations set forth in this Section 9.5, entitled to assume control of and appoint lead counsel for such defense; provided, however, that the indemnifying Person shall not have the right to assume control of the defense of any Asserted Liability (i) to the extent that the object of such Asserted Liability is to obtain an injunction, restraining order, declaratory relief or other non-monetary relief against the indemnified Person which, if successful, would materially adversely affect the Business, operations, Assets, or financial condition of the indemnified Person, or (ii) if the named parties to any such action or proceeding (including any impleaded parties) include both indemnified Persons and the indemnifying Person and the former shall have been advised in writing by counsel (with a copy to the indemnifying Person) that there are one or more legal or equitable defenses available to them that are different from or additional to those available to indemnifying Persons; provided, further, however, that to exercise such rights the indemnifying Person must give notice to the indemnified Person within 90 days after receipt of any such Claims Notice whether it is assuming control of and appointing lead counsel for such defense. If the indemnifying Person does not give such notice within such 90-day period, then the indemnified Person shall have the right to assume control of the defense thereof at the cost and expense of the indemnifying Person, subject to the limitations of liability and other limits set forth in Section 9.3(a).

(c) If the indemnifying Person shall assume the control of the defense of the Asserted Liability in accordance with the provisions of this Section 9.5, (i) the indemnifying

Person shall obtain the prior written consent of the indemnified Person (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement, compromise, admission or acknowledgement of the validity of such Asserted Liability if the settlement does not unconditionally release the indemnified Person and, if applicable, any of the affected Companies, from all liabilities and obligations with respect to such Asserted Liability or the settlement imposes any non-monetary, injunctive or other equitable relief against the indemnified Person or, if applicable, any Company and (ii) the indemnified Person shall be entitled to participate, at its own cost and expense, in the defense of such Asserted Liability and to employ separate counsel of its choice for such purpose.

(d) If the indemnified Person shall assume the control of the defense of any Asserted Liability in accordance with the provisions of this Section 9.5, (i) the indemnified Person shall obtain the prior written consent of the indemnifying Person (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement, compromise, admission or acknowledgement of the validity of such Asserted Liability and (ii) the indemnifying Person shall be entitled to participate, at its cost and expense, in the defense of such Asserted Liability and to employ separate counsel of its choice for such purpose.

(e) Each Party shall cooperate, and cause their respective Affiliates to cooperate, in the defense or prosecution of any Asserted Liability arising from a third party action and shall furnish or cause to be furnished such records, information and testimony (subject to any applicable confidentiality agreement), and attend such conferences, discovery proceedings, hearings, trials or appeals as may be reasonably requested in connection therewith.

9.6 Waiver of Other Representations.

(a) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IT IS THE EXPLICIT INTENT OF EACH PARTY, AND THE PARTIES HEREBY AGREE, THAT NONE OF SELLER NOR ANY OF ITS AFFILIATES OR THEIR RESPECTIVE REPRESENTATIVES HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WRITTEN OR ORAL, INCLUDING ANY IMPLIED REPRESENTATION OR WARRANTY AS TO THE CONDITION, MERCHANTABILITY, USAGE, SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE WITH RESPECT TO THE COMPANY INTERESTS, THE ASSETS OF THE COMPANIES, THE COMPANIES OR ANY OF THE ASSETS OF THE COMPANIES, OR ANY PART THEREOF, EXCEPT THOSE REPRESENTATIONS AND WARRANTIES EXPRESSLY CONTAINED IN ARTICLE III.

(b) EXCEPT THOSE REPRESENTATIONS AND WARRANTIES EXPRESSLY CONTAINED IN ARTICLE III, SELLER’S INTERESTS IN THE COMPANIES ARE BEING TRANSFERRED THROUGH THE SALE OF THE COMPANY INTERESTS “AS IS, WHERE IS, WITH ALL FAULTS,” AND SELLER AND ITS AFFILIATES AND THEIR RESPECTIVE REPRESENTATIVES EXPRESSLY DISCLAIM ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND OR NATURE, EXPRESS OR IMPLIED, AS TO THE CONDITION, VALUE OR QUALITY OF THE COMPANIES AND THEIR ASSETS OR THE PROSPECTS (FINANCIAL OR OTHERWISE), RISKS AND OTHER INCIDENTS OF THE COMPANIES AND THEIR ASSETS.

9.7 Waiver of Remedies.

(a) The Parties hereby agree that no Party shall have any liability, and neither Party nor any of their respective Affiliates shall make any Claim, for any Loss or any other matter, under, relating to or arising out of this Agreement (including breach of representation, warranty, covenant or agreement) or any other Contract or other matter delivered pursuant hereto, whether based on contract, tort, strict liability, other Laws or otherwise, except as expressly provided herein.

(b) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NO PARTY NOR ANY OF ITS AFFILIATES SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES (INCLUDING ANY DAMAGES ON ACCOUNT OF LOST PROFITS OR OPPORTUNITIES, OR LOST OR DELAYED BUSINESS BASED ON VALUATION METHODOLOGIES ASCRIBING A DECREASE IN VALUE TO THE COMPANIES, ON THE BASIS OF A MULTIPLE OF A REDUCTION IN A MULTIPLE-BASED OR YIELD-BASED MEASURE OF FINANCIAL PERFORMANCE), WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER PARTY’S OR ANY OF ITS AFFILIATES’ SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT, (“NON-REIMBURSABLE DAMAGES”) PROVIDED HOWEVER, THAT THE TERM “NON-REIMBURSABLE DAMAGES” SHALL NOT INCLUDE, AND THIS SECTION 9.7(b) SHALL NOT LIMIT AN INDEMNIFIED PERSON’S RIGHT TO INDEMNIFICATION WITH RESPECT TO, ANY SUCH DAMAGES ACTUALLY INCURRED BY SUCH INDEMNIFIED PERSON IN CONNECTION WITH A THIRD PARTY CLAIM.

9.8 Access to Information. After the Closing Date, Seller and Buyer shall grant each other (or their respective designees), and Buyer shall cause the Companies to grant to Seller (or its designee), access at all reasonable times to all of the records relating to the Companies in its possession or the possession of the Companies, and shall afford such party the right (at such party’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to implement the provisions of, or to investigate or defend any Claims among the Parties and/or their Affiliates arising under, this Agreement. Buyer shall maintain, and shall cause the Companies to maintain, such records until the seventh anniversary of the Closing Date (or for such longer period of time as Seller shall advise Buyer is necessary in order to have records available with respect to Tax matters), or if any of the records pertain to any Claim or Dispute pending on the seventh anniversary of the Closing Date, Buyer shall maintain any of the records designated by Seller or its Representatives until such Claim or Dispute is finally resolved and the time for all appeals has been exhausted.

9.9 Dispute Resolution and Arbitration.

(a) In the event of any dispute, controversy or Claim among the Parties, or any of them, arising out of or relating to this Agreement, or the breach or invalidity thereof (collectively, a “Dispute”), the Parties shall attempt in the first instance to resolve such Dispute through friendly consultations between senior management of the Parties. The Parties agree to attempt to resolve all Disputes arising hereunder promptly, equitably and in a good faith manner.

The Parties further agree to provide each other with reasonable access during normal business hours to any and all non-privileged records, information and data pertaining to such Dispute, upon reasonable advance notice.

(b) If such consultations do not result in a resolution of the Dispute within 30 Business Days after written notice by a Party to the other Parties describing the Dispute and requesting friendly consultation, then the Dispute may be submitted by any Party to binding arbitration pursuant to the terms of this Section 9.9, irrespective of the magnitude thereof, the amount in dispute or whether such Dispute would otherwise be considered justifiable or ripe for resolution by any court or arbitral tribunal, by giving written notice thereof to the other Parties; provided, however, that in no event shall a Party have the right to submit the Dispute to arbitration if the institution of legal or equitable proceedings based on such Dispute would be barred by any applicable statute of limitations or Section 9.1.

(c) Any Dispute shall be settled exclusively and finally by binding arbitration in accordance with the provisions of this Section 9.9.

9.10 Arbitration Procedures.

(a) Any Party electing to arbitrate a Dispute shall designate its nomination for an arbitrator in its notice to the other Party electing to submit the Dispute to arbitration. Each Party receiving such notice shall, within 10 Business Days thereafter, by return written notice to all Parties, state whether it will accept such nomination, or decline to accept it and designate its nomination for an arbitrator. One arbitrator shall control the proceedings if such nomination of an arbitrator is accepted by all Parties or if the receiving Party fails to nominate an arbitrator within the required 10 Business Day period. If the receiving Party timely nominates an arbitrator, the arbitral tribunal shall consist of three arbitrators, with one arbitrator being selected by Seller and one arbitrator being selected by Buyer, within five Business Days after the expiration of the 10 Business Day period reference above, and the two selected arbitrators choosing a third arbitrator, which third arbitrator must be a Person with the requisite knowledge and experience to make a fair and informed determination with respect to the matter in dispute, which Person shall not be an Affiliate of any Party, nor an employee, director, officer, shareholder, owner, partner, agent or a contractor of any Party or of any Affiliate of any Party, either presently or at any time during the previous two years. In the event the arbitrators fail to appoint the third arbitrator within 30 days after they have accepted their appointment, the third arbitrator (meeting the qualifications specified in the preceding sentence) shall be appointed by the Houston office of the American Arbitration Association. The arbitration shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, as supplemented to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United Stated Code). If there is an inconsistency between this Section 9.10 and the Commercial Arbitration Rules or the Federal Arbitration Act, the provisions of this Section 9.10 shall prevail.

(b) Within 10 Business Days after the selection of the arbitrator(s), each Party shall submit to the arbitrator(s) such Party’s proposal for resolution of the Dispute, which such proposal shall not conflict with the terms and conditions of this Agreement, together with the supporting data, if any, that was used to determine such proposal. Within 30 days after the

proposals are submitted, the arbitrator(s) shall hold a hearing during which the Parties may present evidence in support of their respective proposals. The arbitrator(s) (by majority rule if there are three arbitrators) will determine the outcome of the Dispute. The cost of the arbitration shall be split between the Parties equally and each Party shall pay for one half of the costs.

(c) The place of arbitration shall be Houston, Texas, unless in any particular case the Parties agree upon a different venue.

(d) The arbitrator(s) shall have no right or authority to grant or award Non-Reimbursable Damages.

(e) Any decision of the arbitrator(s) pursuant to this Section 9.10 shall be final and binding upon the Parties. The Parties agree that the arbitral award may be enforced against the Parties to the arbitration proceeding or their Assets wherever they may be found and that a judgment upon the arbitral award may be entered in any court having competent jurisdiction thereof. The Parties expressly submit to the jurisdiction of any such court. The Parties hereby waive, to the extent permitted by Law, any rights to appeal or to review of such award by any court or tribunal.

(f) When any Dispute occurs and is the subject of friendly consultations or arbitration, the Parties shall continue to make payments of undisputed amounts in accordance with this Agreement, and the Parties shall otherwise continue to exercise their rights and fulfill their respective obligations under this Agreement. While any friendly consultations or arbitration is pending, no Party shall exercise any other remedies hereunder arising by virtue of the matters in Dispute.

9.11 Determination of Amount of Damages; Mitigation. The Losses giving rise to any indemnification obligation hereunder shall be limited to the actual loss suffered by the indemnified Person and shall be reduced by any insurance proceeds or other payment or monetary recoupment actually received by the indemnified Person as a result of the events giving rise to the claim for indemnification. Any indemnified Person that becomes aware of Losses for which it intends to seek indemnification hereunder shall use commercially reasonable efforts to collect any amounts to which it may be entitled under insurance policies or from third parties (pursuant to indemnification agreements or otherwise) and shall use commercially reasonable efforts to mitigate such Losses, provided that in the event that Buyer is the indemnified Person, Buyer shall promptly notify Seller of any efforts to mitigate. Notwithstanding the foregoing, neither the Buyer nor any Company shall be required to pursue any claims against any customer of any Company or against any employees of any Company; provided, however, that, to the extent neither Buyer nor the Company choose to pursue any such claim, Seller shall have full rights of substitution and subrogation to pursue any such claims against such customers and/or employees with the same rights as if they were Buyer and Buyer shall (and shall cause the Companies to) execute powers of attorney, assignments or such other documents as reasonably requested to permit Seller to exercise such rights.

9.12 Set Off. In addition to any right that a Buyer Indemnified Party may have to seek payment for amounts owed to it under this Article IX from the Indemnity Escrow Account, Buyer may, to the extent provided in this Agreement, set off any amount to which it or any Buyer Indemnified Party may be entitled under this Article IX against the Earnout Amount otherwise payable to Seller under this Agreement.

10.4 Disclosure. Seller may, at its option, include in the Schedules items that are not material, and any such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgment or representation that such items are material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement.

Earnout Provisions

Section 1. Earnout. Upon the terms and subject to the conditions of this Section 1, Buyer shall deliver to Seller the dollar amount (if any) that becomes payable in accordance with the provisions of this Section 1.

(a) Quarterly Financial Statements. Within 45 days following the end of each of the first three calendar quarters during each year of the Earnout Period, Buyer shall (i) prepare (or cause to be prepared) an unaudited statement of income for the Company for such calendar quarter in accordance with this Agreement and GAAP (except for notes and subject to normal year-end audit adjustments, and including (x) a calculation of EBITDA and (y) a description of (1) any acquisition made by Buyer or any of its Affiliates of assets or companies that are in the same business as the Business or (2) any Divestiture made by the Company) (“Quarterly Financial Statements”) and (ii) deliver the Quarterly Financial Statements to Seller. The Quarterly Financial Statements shall be provided for information purposes only and shall not prevent any Party from taking a contrary position with respect to the information contained therein.

(b) Delivery of Earnout Statement. Within 30 days following receipt by the Company of its annual audit for each year during the Earnout Period, Buyer shall deliver a copy to Seller of an Earnout Statement.

(c) Review. Following the delivery of an Earnout Statement to Seller, Buyer and the Company shall afford Seller and its Representatives the opportunity to examine the Earnout Statement and such supporting schedules, analyses, workpapers, including any audit workpapers, and other underlying records or documentation as are reasonably necessary and appropriate. Buyer and the Company shall cooperate fully and promptly with Seller and its Representatives in such examination, including providing answers to questions asked by Seller and its Representatives, and Buyer and the Company shall promptly make available to Seller and its Representatives any records under their control that are reasonably requested by Seller and its Representatives and are relevant to the Earnout Statement.

(d) Dispute. If within 60 days following receipt of an Earnout Statement, Seller has not delivered to Buyer written notice (the “Objection Notice”) objecting to the Earnout Statement and specifying in reasonable detail the basis for the objection, then that Earnout Statement shall be deemed final and binding on the parties. If Seller delivers the Objection Notice in accordance with the preceding sentence, then Buyer and Seller shall endeavor in good faith to resolve the objections, for a period not to exceed 30 days following delivery of the Objection Notice. If at the end of such 30-day period there are any objections that remain in dispute with respect to the Earnout Statement, then the items in the Objection Notice that remain in dispute (the “Disputed Items”) may be submitted by either Party for resolution to the Accounting Firm pursuant to the procedures set forth in Section 2.6(b) of this Agreement, except as expressly provided in this Section 1(d). If any Disputed Items are

submitted to the Accounting Firm for resolution, each Party shall furnish to the Accounting Firm such workpapers and other documents and information relating to such objections as the Accounting Firm may reasonably request and are available to that Party or its Affiliates (or its independent public accountants) and will be afforded the opportunity to present to the Accounting Firm any material relating to the determination of the matters in dispute and to discuss such determination with the Accounting Firm. Once the Accounting Firm determines all such Disputed Items, the Accounting Firm shall calculate EBITDA by taking into account all components of such calculation not disputed by the Parties, the Accounting Firm’s determination with respect to each Disputed Item and the terms of this Agreement. The Accounting Firm shall make its calculation of EBITDA in accordance with this Agreement and shall set forth such calculation in reasonable detail in a written notice and deliver such notice to both Parties, and such calculation shall (except in the case of fraud or manifest error) be binding and conclusive on the Parties and constitute final, binding and unappealable determination, on the basis of which, in the case of the Final Earnout Statement, a judgment may be entered by a court having jurisdiction thereof and shall constitute the final and binding Earnout Statement for the relevant period for all purposes under this Agreement.

(e) Expenses. Buyer and Seller shall each bear their own fees and expenses in connection with any proceeding under this Section 1(e); provided, however, that Buyer and Seller shall each be responsible for payment of 50% of the fees and expenses of the Accounting Firm with respect to such proceeding.

(f) Calculation and Payment of Earnout Amount. When the Final Earnout Statement becomes final and binding in accordance with Section 1(d), Buyer shall pay to Seller a dollar amount (the “Earnout Amount”) equal to the amount (if any) by which [**REDACTED**]; provided that the maximum Earnout Amount payable by Buyer to Seller shall be $50,000,000. Buyer shall deliver any Earnout Amount pursuant to this Section 1(f), less any amount paid pursuant to Section 1(g) or set off pursuant to Section 1(i), to Seller within ten Business Days after the date that the Final Earnout Statement becomes final and binding in accordance with Section 1(d) (the “Earnout Payment Date”), by wire transfer of immediately available funds pursuant to wire transfer instructions provided by Seller in writing.

[**CONFIDENTIAL TREATMENT REQUESTED PURSUANT TO RULE 24b-2 OF THE SECURITIES EXCHANGE ACT OF 1934**]

(g) Payment of Amounts Not in Dispute. Notwithstanding anything in this Agreement to the contrary, if an Objection Notice has been delivered pursuant to Section 1(d) with respect to the Final Earnout Statement, the portion of the Earnout Amount (if any) that is not in dispute shall be paid within five Business Days after the date that the Objection Notice is delivered.

(h) Interest. All payments pursuant to this Section 1 shall be without interest for any periods during the Earnout Period but shall accrue interest until paid at the Past Due Rate from and after the date which is the earlier of (i) that date that is 30 days after the date the Earnout Statement is due pursuant to Section 1(b) relating to the year ended December 31, 2013 and (ii) the date that is 30 days after the date Buyer provides the Earnout Statement relating to

the year ended December 31, 2013. For the purposes of this Agreement, (A) the term “Past Due Rate” means the lesser of (1) the maximum nonusurious rate permitted by law and (2) LIBOR plus 2% per annum, and (B) “LIBOR” means on any day, the interest rate per annum equal to the rate per annum reported on such day (or if such day is not a Business Day, on the prior Business Day) in the eastern edition of The Wall Street Journal “Money Rates” section as the one-month London Interbank Offered Rate for U.S. dollar deposits.

(i) Right of Setoff. Buyer shall have the right to set off against any Earnout Amount otherwise payable by Buyer to Seller under this Section 1 the amount of any Losses for which Buyer is entitled to be indemnified by Seller under Article IX of this Agreement.

(j) Operating Covenants. Buyer shall have the right to operate the business of the Company (including the Business) in the manner it deems appropriate and has no obligation to operate the business of the Company (including the Business) to maximize the Earnout Amount. Buyer will have the right to make any business decisions relating to the Company, including capital expenditures, distribution arrangements, procurement decisions, pricing of products and services and compensation of employees, that Buyer in good faith determines is in the best interest of the Company, its Affiliates and their stockholders. Notwithstanding the foregoing provisions of this Section 1(j), Buyer agrees that it will not take any action with respect to the Business or the Company, the purpose of which is to minimize the Earnout Amount. In addition, during the Earnout Period, Buyer shall, and shall cause the Company to, act in good faith and use commercially reasonable efforts to:

(i) allow representatives designated by Seller to (A) review and retain copies of all books and records, documents and work papers related to such operations, (B) interview management of the Company and its Affiliates as reasonably requested and (C) discuss such operations with a representative designated by Buyer; provided, however, that any such review or discussion shall be done in such a manner so as not to unreasonably interfere with the normal conduct of Buyer’s or the Company’s business;
