Purchaser shall, within 5 days after such rejection, select a mutually acceptable and nationally recognized independent accounting firm (such firm, the “Independent Accounting Firm”) to resolve the remaining disputed items (the “Remaining Disputed Items”) by conducting a review and verification of the Final Purchase Price Calculation Statement, and thereafter selecting either Seller’s Calculations of the Remaining Disputed Items or Purchaser’s Calculations of the Remaining Disputed Items or an amount in between the two. Seller and Purchaser shall be bound by the written determination of the Remaining Disputed Items by the Independent Accounting Firm. Each of Purchaser and Seller agrees to execute, if requested by the Independent Accounting Firm, an engagement letter containing reasonable and customary terms. Each of Purchaser and Seller agrees that there shall be no ex parte communications between either party, on the one hand, and the Independent Accounting Firm, on the other hand, during the Independent Accounting Firm’s review and verification of the Final Purchase Price Calculation Statement. Purchaser and Seller shall each pay their own costs and expenses incurred under this Section 3.3(b). The costs and expenses of the Independent Accounting Firm shall be borne one-half by Purchaser and one-half by Seller.

(c) Payment After Recalculation. Upon the determination, in accordance with Section 3.3(b), of the Final Purchase Price Calculation Statement and the final calculations of the amounts of (A) Selling Expenses, (B) Closing Date Indebtedness and (C) Closing Cash calculated by reference thereto, the Aggregate Purchase Price shall be recalculated using such finally determined amounts in lieu of the estimates of such amounts used in the calculation of the estimated Aggregate Purchase Price paid at the Closing.

(i) If the Aggregate Purchase Price as recalculated pursuant to this Section 3.3(c) is greater than such estimated Aggregate Purchase Price, then Purchaser shall pay or cause to be paid to Seller the amount of any such excess.

(ii) If the Aggregate Purchase Price as recalculated pursuant to this Section 3.3(c) is equal to such estimated Aggregate Purchase Price, then no further payment shall be payable by Purchaser or Seller under this Section 3.3(c).

(iii) If the Aggregate Purchase Price as recalculated pursuant to this Section 3.3(c) is less than such estimated Aggregate Purchase Price, then Seller shall pay or cause to be paid to Purchaser the amount of such deficiency.

(iv) Any payment made pursuant to this Section 3.3(c) shall be made by wire transfer of immediately available funds no later than three Business Days after the final determination referred to in the first sentence of this Section 3.3(c) and shall be deemed to be adjustments to the Aggregate Purchase Price for all purposes, including Tax purposes.

(e) From and after the date hereof until the determination of the Final Purchase Price Calculation in accordance with Section 3.3(b), (i) Purchaser shall, and shall cause the Company to, provide Seller and its Representative reasonable access during normal business hours to the financial books and records pertaining to the

Company and (ii) Seller and Willbros shall provide Purchaser and its Representatives reasonable access during normal business hours to the financial books and records pertaining to the Company, in each case to the extent reasonably necessary to prepare and assess Purchaser’s Calculations or Seller’s Calculations, as applicable.

(a) The Aggregate Purchase Price, (to the extent properly taken into account under the Code, and including any other relevant items, including Indebtedness), shall be allocated among the assets of Utility Services in accordance with section 1060 of the Code and the U.S. Treasury Regulations promulgated thereunder (and any similar provision of state, local or foreign law, as appropriate) (the “Allocation”). The Allocation shall be delivered by Purchaser to Seller within 30 days after the determination of the Final Purchase Price Calculation in accordance with Section 3.3(b) for Seller’s approval, which approval shall be delivered in writing and not unreasonably withheld. Seller and Purchaser shall work in good faith to resolve any disputes relating to the Allocation within 30 days of Seller’s receipt of the Allocation. If Seller and Purchaser are unable to resolve any such dispute, such dispute shall be resolved promptly in writing by the Independent Accounting Firm. Each of Purchaser and Seller agrees to execute, if requested by the Independent Accounting Firm, an engagement letter containing reasonable and customary terms. Each of Purchaser and Seller agrees that there shall be no ex parte communications between either party, on the one hand, and the Independent Accounting Firm, on the other hand, during the Independent Accounting Firm’s review and verification of the Allocation. Purchaser and Seller shall each pay their own costs and expenses incurred under this Section 3.4(a). The costs and expenses of the Independent Accounting Firm shall be borne one-half by Purchaser and one-half by Seller.

(b) If the Purchase Price is adjusted pursuant to Section 3.3, the Allocation shall be adjusted in a manner consistent with the procedures set forth in Section 3.4(a).

(c) Purchaser and Seller shall file all Returns (including, but not limited to, Internal Revenue Service Form 8594) consistent with the Allocation. Neither Purchaser nor Seller shall take any Tax position inconsistent with such Allocation and neither Purchaser nor Seller shall agree to any proposed adjustment to the Allocation by any Tax Authority without first giving the other party prior written notice; provided, however, that nothing contained herein shall prevent Purchaser or Seller from settling any proposed deficiency or adjustment by any Tax Authority based upon or arising out of the Allocation, and neither Purchaser nor Seller shall be required to litigate before any court any proposed deficiency or adjustment by any Tax Authority challenging such Allocation.

(a) During the period commencing at the Closing and ending on the date which is 12 months from the Closing (or, if earlier, the date of the employee’s termination of employment with the Company), Purchaser shall provide (or shall cause the Company or their Affiliate to provide, as applicable), each employee who is employed by the Company immediately prior to the Closing who remains employed immediately after the Closing (“Company Continuing Employee”) with compensation and benefits (including base salary or hourly wages, target bonus opportunities (excluding equity-based compensation), retirement and welfare benefits, and severance benefits) that are substantially comparable in the aggregate to the compensation and benefits provided by Purchaser to its similarly-situated employees; provided that, notwithstanding the foregoing, Purchaser shall not materially change the aggregate compensation and benefits of any such Company Continuing Employee during the 90-day period immediately following Closing.

(c) With respect to any employee benefit plan maintained by Purchaser or its Subsidiaries (collectively, “Purchaser Benefit Plans”) in which any Company Continuing Employees will participate effective as of or after the Closing, Purchaser shall use its reasonable best efforts to, or to cause the Company to, recognize all service of the Company Continuing Employees with the Company as if such service were with Purchaser, for vesting and eligibility purposes in any Purchaser Benefit Plan (but not for benefit accrual purposes under any defined benefit plan) in which such Company Continuing Employees may be eligible to participate after the date hereof, to the extent permitted by the terms of the applicable Purchaser Benefit Plan and applicable Law; provided, however, such service shall not be recognized to the extent that (x) such recognition would result in a duplication of benefits or (y) such service was not recognized under the corresponding Benefit Plan. To the extent that a Company Continuing Employee participating in the defined contribution 401(k) Plan prior to the Closing elects a direct transfer or rollover of assets, including an outstanding loan of such Company Continuing Employee under such defined contribution 401(k) Plan, Purchaser agrees to use its reasonable best efforts to cause the applicable Purchaser Benefit Plan to accept a direct transfer or rollover of assets from the defined contribution 401(k) Plan in which the Company Continuing Employees participated prior to the Closing, including, but not limited to, outstanding loans under such defined contribution 401(k) Plan.

(d) Purchaser shall assume responsibility for providing COBRA notice and coverage to any M&A qualified beneficiaries (within the meaning of Treas. Reg.

Purchaser shall assume responsibility for providing any remaining period of COBRA coverage for any qualified beneficiaries who experience a qualifying event prior as of or to the Closing and who were formerly employed by the Company.

(e) This Section 8.10 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 8.10, express or implied, shall confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 8.10.

The parties hereto acknowledge and agree that (i) the terms set forth in this Section 8.10 shall not create any third-party beneficiary or other right in any employee or any other Person to any continued employment for any period of time following the Closing with the Company, Purchaser or any of their respective Affiliates or to compensation or benefits of any nature or kind whatsoever, and (ii) nothing in this Section 8.10 shall prohibit Purchaser, the Company or any of their respective Affiliates from terminating the employment of any employee at any time following the Closing, subject to any obligations of Purchaser to provide severance benefits pursuant to this Section 8.10.

(a) In connection with the Stray Voltage Contribution, as promptly as practicable following the Closing, Seller shall use its reasonable best efforts to replace, substitute or otherwise remove the Company and any of its Affiliates (including Purchaser and any of its Affiliates) as a party in interest to the Power Survey Proceeding. For the avoidance of doubt, such replacement, substitution or removal shall not affect any of the rights or obligations of the respective parties set forth in this Section 8.11.

(b) The parties hereto agree that Seller shall have the right to, at the sole cost and expense of Seller, determine and control all aspects of the Power Survey Proceeding and the Power Survey Patent Challenge, including the assertion or defense of any claims related thereto or the negotiation, resolution or settlement thereof; provided, however, that, notwithstanding the foregoing, Seller and Willbros shall not, and shall cause each of their respective Affiliates and Representatives not to, make any material pleading, filing or motion or take any other material action with respect to the Power Survey Proceeding or the Power Survey Patent Challenge without the prior input and consent of Purchaser. Without limiting Section 9.2(a)(iv), Seller and Willbros shall be responsible for, and indemnify and hold the Purchaser Indemnified Parties harmless from, any fees or expenses of one national law firm (which may include Latham & Watkins LLP), and an additional local law firm in any jurisdiction of any Authority adjudicating the Power Survey Proceeding representing the Company in connection with the Power Survey Proceeding, and such fees and expenses shall, for the avoidance of doubt, be included as Damages indemnifiable pursuant to Section 9.2(a)(iv); provided that, without limiting any other Damages for which Seller and Willbros are responsible hereunder with respect to the Power Survey Patent Challenge, any fees or expenses of counsel hired by by any Purchaser Indemnified Parties solely with respect to such Purchaser Indemnified Party’s voluntary participation in the Power Survey Patent Challenge pursuant to this Section 8.11(b) shall be borne by Purchaser, and notwithstanding anything herein to the contrary (including Section 9.2(a)(iv)), Seller and Willbros shall have no obligation to indemnify or otherwise reimburse any Purchaser Indemnified Party for any such legal fees or expenses.

(c) From and after the Closing, upon the reasonable request and at the sole cost and expense of Seller, Purchaser shall, and shall cause the Company to, use its or their commercially reasonable efforts to provide all cooperation reasonably requested by Seller in connection with the Power Survey Proceeding assumed by Seller, including: (i) taking all action reasonably requested by Seller relating to the assertion, defense, negotiation, resolution or settlement of any claims or causes of action related to the Power Survey Proceeding, including making, executing and delivering all such agreements (including any engagement letters for dispute accountants and other experts or arbiters of fact), consents, instruments or other documents as Seller may reasonably request, (ii) providing any books, records, work papers, memoranda or other documents or information of the Company and its Representatives, in each case, related to the Power Survey Proceeding that may be reasonably requested by Seller, (iii) providing Seller with reasonable access (at reasonable times and upon reasonable notice) to senior management of the Company as may be reasonably requested by Seller in connection with Seller’s

assertion, defense, negotiation, resolution or settlement of any claims or causes of action related to the Power Survey Proceeding, including making such members of senior management reasonably available to serve as a witness or otherwise participating in any meeting, discussion or proceeding related to the Power Survey Proceeding, (iv) promptly forwarding all written correspondence and keeping Seller reasonably apprised of any oral correspondence it may receive relating to the Power Survey Proceeding, (v) taking, or causing to be taken, all such further actions as may be reasonably requested by Seller and necessary to carry out the intent and accomplish the purposes of this Section 8.11.

(d) Notwithstanding anything else to the contrary contained in this Agreement, nothing in this Section 8.11 shall require any cooperation by Purchaser, the Company or their respective Representatives to the extent that it would unreasonably interfere with the ongoing business or operations of Purchaser or the Company.

(e) Notwithstanding anything to the contrary, in no event shall Seller consent to the entry of any judgment or enter into any settlement with respect to the Power Survey Proceeding or Power Survey Patent Challenge binding upon or otherwise relating to the Company and any of its Affiliates without the prior written consent of Purchaser (which consent shall not be unreasonably withheld or delayed); provided, that, without limitation, it shall not be unreasonable for Purchaser to withhold its consent with respect to any such judgment or settlement that (i) does not contemplate the entry of a final, non-appealable order by a court of competent jurisdiction, or the binding and due execution and delivery of a settlement agreement, in each case in full satisfaction and resolution of the Power Survey Proceeding or Power Survey Patent Challenge, as applicable, without any Liability (absolute, contingent or otherwise) or obligation of Purchaser, the Company and their respective Affiliates and Representatives with respect to the Power Survey Proceeding, other than any obligation only to pay a fixed amount of cash in an amount that is less than the amount remaining in the Escrow Account as of the date of such judgment or settlement, (ii) does not include an express, unconditional release of the Company and its Affiliates and Representatives from any and all liabilities or obligations with respect to the Power Survey Proceeding or Power Survey Patent Challenge, as applicable or (iii) provides for injunctive or other non-monetary relief or is conditioned upon, coupled with or otherwise related to or otherwise results in (or could reasonably be expected to result in) the waiver, termination, relinquishment, interpretation or amendment of any actual or asserted rights of Purchaser, the Company or any of their respective Affiliates or Representatives.

(f) Except as expressly otherwise provided in Section 8.11(b), Seller shall, promptly upon request by Purchaser, reimburse Purchaser or the Company for all out-of-pocket fees, costs and expenses incurred in connection with the matters contemplated by this Section 8.11.

8.12. Insurance Claims. Neither Seller nor Willbros shall, and shall cause their respective Affiliates not to, take any action after the Closing to impede or impair the rights of the Company to make a claim under any of the Insurance Policies to the extent such claim relates to losses of the Company that arise out of any act, omission, occurrence, fact or circumstance existing on or prior to the Closing. Without limiting the rights of Purchaser or the Company elsewhere in this Agreement, if (a) any claims under the Insurance Policies are made prior to the date hereof or (b) any losses occur prior to the date hereof in respect of which claims may be made against the Insurance Policies or any other insurance policies retained by Seller, then Seller shall use commercially reasonable efforts to ensure that Purchaser or the Company, as applicable, can file notice and otherwise continue to pursue such claims and recover proceeds under the terms of such policies, and Seller and Willbros each agree to otherwise cooperate with Purchaser, the Company and/or their respective Affiliates to make the benefits of any such insurance policies available to the Company; provided, that (i) such claims will be subject to (and recovery thereon will be reduced by the amount of) any applicable deductibles, retentions, self-insurance provisions or any payment or reimbursement obligations of Seller, Willbros or any of their respective Affiliates in respect thereof and (ii) such claims shall be subject to all of the terms and conditions of such insurance policies.

(a) From and after the Closing, Seller, Willbros and their respective Affiliates shall, and shall cause each of their respective Representatives to, treat as confidential any information relating to or obtained from Purchaser or its Affiliates (including the Company) that Seller, Willbros or their respective Affiliates would not have obtained or had access to but for Seller’s (and its Affiliates’) acquisition and ownership of the Company prior to the Closing, or which is confidential or proprietary and/or trade secrets disclosed by Purchaser or such Affiliates (including the Company) or that, by virtue of the nature of the information or the circumstances surrounding disclosure, a reasonable party would understand to be confidential and/or proprietary and/or trade secrets, regardless of the form in which such information is communicated or maintained, and all notes, reports, analyses, compilations, studies, files or other documents or material, whether prepared by Purchaser, its Affiliates (including the Company) or their respective Representatives, which are based on, contain or otherwise reflect such information, except that the foregoing requirements of this Section 8.13(a) shall not apply to the extent that (A) any such information becomes available to the public other than as a result of disclosure by Seller, Willbros, any of their respective Affiliates or any of their respective Representatives in breach of this Section 8.13 or (B) any such information was or becomes available to Seller or Willbros on a non-confidential basis, directly or indirectly, from a source (other than a party to this Agreement or any Affiliate or Representative of such party) that is not known by Seller, Willbros, their respective Affiliates or any of their respective Representatives to be bound by any confidentiality obligation to Purchaser, its Affiliates (including the Company) or any of their respective Representatives with respect to such information, or otherwise known by Seller, Willbros, their respective Affiliates or any of their respective Representatives to be prohibited from transmitting the information to Seller, Willbros, their respective Affiliates or any of their respective Representatives by a contractual, legal or fiduciary obligation. Seller and Willbros shall instruct their respective Affiliates and their

respective Representatives having access to such information of such obligation of confidentiality and agree that they are responsible for any action or failure to act that would constitute a breach or violation of this Section 8.13 by such Affiliates or Representatives.

(b) Notwithstanding anything in Section 8.13(a) to the contrary, in the event that any of Seller, Willbros or their respective Affiliates or Representatives is requested or required under applicable Law or the applicable rules or regulations of any securities exchange or similar self-regulatory organization having jurisdiction over such party, its Affiliates or its Representatives, as applicable (including by oral questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process), to disclose any information required to be treated as confidential pursuant to Section 8.13(a), it is agreed that Seller or Willbros, as applicable, shall, as promptly as reasonably practicable (i) inform Purchaser of the terms of any such request or requirement to the extent permitted by applicable Law, (ii) consult with Purchaser on the advisability of taking legally available measures to resist or narrow any such request or requirement, and (iii) cooperate with Purchaser, at Purchaser’s expense, in pursuing any such reasonable measures that Purchaser determines to pursue to resist or narrow any such request or requirement. In the event that disclosure of such information is ultimately required, the disclosing party shall, to the extent permitted by applicable Law, give Purchaser written notice of the information to be disclosed as far in advance of its disclosure as is practicable and then may furnish that portion (and only that portion) of such information which it is required to disclose under such applicable Laws or rules or regulations, and Seller, Willbros, their respective Affiliates and their respective Representatives shall cooperate with Purchaser, at the expense of Purchaser, in its reasonable efforts to obtain an order or other reliable assurance that confidential treatment will be accorded any information so furnished.

(c) Each of the parties hereto agrees that this Agreement and the other Transaction Documents and the terms and conditions set forth herein and therein shall be kept strictly confidential and shall not be disclosed or otherwise made available to any other Person and that copies of this Agreement and the other Transaction Documents shall not be publicly filed or otherwise made available to the public, except where such disclosure, availability or filing is required by applicable Law or under the rules of any securities exchange on which Seller or Purchaser or any of their respective Affiliates are listed, and then only to the extent required by such Law or rules, as applicable. Notwithstanding anything to the contrary in this Agreement or the Confidentiality Agreement, in no event shall either this Section 8.13 or any provision of the Confidentiality Agreement limit disclosure by Purchaser or any of its Affiliates to any direct or indirect investors in any such Person, as applicable, or in connection with normal fund raising and related marketing or informational or reporting activities of Purchaser or any such Affiliate. The foregoing shall not prevent any of the parties hereto, Purchaser’s equity owners and their respective Affiliates from disclosing such information to their respective employees, equity owners, partners, prospective partners, investors, prospective investors, professional advisors, lenders and prospective lenders, in each case, who agree in writing to keep such information confidential or are otherwise bound to confidentiality obligations with respect to such information.

(a) From the Closing until the fifth anniversary of the date hereof, Seller and Willbros shall not, and shall cause their respective Affiliates not to, directly or indirectly, on behalf of itself or any other Person solicit, bid for, entice, induce, cause or encourage, directly or indirectly, any Person who is a customer or supplier of the Company to reduce or end their business with the Company; provided, however, that soliciting, bidding for, enticing, inducing, causing and encouraging any Person to hire or otherwise use Seller, Willbros or any of their respective Affiliates for services that are not Covered Services shall not, in and of itself, constitute a violation of this Section 8.14(a).

(b) From the Closing until the fifth anniversary of the date hereof, Seller and Willbros shall not, and shall cause their respective Affiliates not to, directly or indirectly, on behalf of itself or any other Person, solicit the employment of, enter into a Contract with or otherwise solicit, entice, induce, cause or encourage, directly or indirectly, any employee, consultant, independent contractor, sales or other representative of the Company to leave the employ or service of the Company, provided, however, that from and after the second anniversary of the date hereof, none of Seller, Willbros, and their respective Affiliates shall be prohibited from employing any employee, consultant, independent contractor, sales or other representative of the Company who contacts Seller, Willbros, or their respective Affiliates in response to a general solicitation not targeted at employees or former employees of the Company or who contacts Seller, Willbros, or their respective Affiliates on his or her own initiative and without any direct or indirect solicitation or other violation of this Section 8.14(b) by Seller, Willbros, or their respective Affiliates.

(c) From the Closing until the fifth anniversary of the date hereof, Seller and Willbros shall not, and shall cause their respective Affiliates not to, whether directly or indirectly, on their behalf or on behalf of any other Person, engage in Covered Services anywhere in North America (including its associated islands, coastal waters, territories and regions, collectively, the “Territory”), including by (i) establishing a Person which engages in Covered Services anywhere in the Territory (a “Competing Entity”), (ii) making any investment in or acquiring any equity interest or other interest (as owner, lender, principal, member, general or limited partner, stockholder, or otherwise) in, a Competing Entity, or (iii) participating in the management (as an officer, director, manager, independent contractor, employee, or otherwise) of a Competing Entity. Seller, Willbros and Purchaser acknowledge that the covenants contained in this Section 8.14(c) are a material inducement to the willingness of Purchaser to enter into this Agreement without which Purchaser would not have consummated the transactions contemplated hereby and are being granted to maintain or preserve the goodwill value of the Company and fair market value of the Units. Notwithstanding the foregoing, neither the provision of Permitted Bundled Services nor the ownership by Seller or Willbros, directly or indirectly, of not more than three percent of the issued and outstanding stock of a company the shares of which are regularly traded on a national securities exchange or over-the-counter market shall be a violation of this Section 8.14(c).

(d) For a period of two years following the date hereof, upon an officer-level manager of Seller or Willbros becoming aware of any opportunity for the Company to provide any Covered Services (other than any Permitted Bundled Services provided directly (without subcontracting) by Seller, Willbros or their respective Affiliates), Seller and Willbros shall, and shall cause their respective Affiliates to, notify Purchaser of such event (and provide reasonable known details thereof) and, to the extent that Seller, Willbros or any of their respective Affiliates has the ability and authority to choose and engage a subcontractor or other third party to perform such Covered Services, Seller and Willbros shall, and shall cause their respective Affiliates to, offer and (subject to the following provisos) engage Purchaser or its Affiliates (including the Company) to perform such Covered Services; provided, that (x) Seller, Willbros and their respective Affiliates shall not be obligated to engage Purchaser or its Affiliates to the extent that Purchaser or its Affiliates are unavailable (after being given a reasonable opportunity) or unwilling to perform such Covered Services at rates, terms and conditions, and subject to quality and safety standards, that are generally in line with the prevailing market rates, terms and conditions and quality and safety standards for such Covered Services, and (y) to the extent that Seller, Willbros or their respective Affiliates do not have the ability and authority to choose and engage a subcontractor or other third party to perform such Covered Services, Seller and Willbros shall, and shall cause their respective Affiliates to, recommend Purchaser and its Affiliates (including the Company) to such customer for the provision of such Covered Services.

(e) Without limiting Section 12.6, if at any time a court or arbitrator’s award holds that the restrictions in this Section 8.14 are unreasonable under circumstances then existing, Seller, Willbros and Purchaser agree that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area. Seller, Willbros and Purchaser acknowledge and agree that any breach of the provisions contained in this Section 8.14 will result in serious and irreparable injury and therefore money damages would not be an adequate remedy for any such breach; and therefore, in the event of a breach or threatened breach of any provisions of this Section 8.14 that is continuing, Purchaser, the Company and their respective successors and permitted assigns, in addition to other rights and remedies existing in their favor, shall be entitled to specific performance or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security). In addition, in the event of a breach of this Section 8.14, the period of non-competition or non-solicitation, as applicable, shall be tolled until such breach has been duly cured.

8.15. Notification of Customers. At Purchaser’s request, Seller and Willbros shall, and shall cause their respective Affiliates and each of their respective Representatives to, reasonably cooperate with Purchaser in Purchaser’s efforts to notify all of the customers and vendors and other commercial counterparties of the Company that ownership of the Company has been transferred to Purchaser and facilitating the transition of such customers, vendors and other commercial counterparties to Purchaser; provided, that Purchaser shall, upon request by Seller, reimburse Seller for all documented and reasonable out-of-pocket costs and expenses incurred by Seller, Willbros or their respective Affiliates in connection with any such cooperation. If the economic benefits of any services performed by the Company (whether before or after Closing),

or any other payments or other funds due to the Company, are received by Seller, Willbros or any of their respective Affiliates from and after the Closing, Seller or Willbros, as applicable, shall take such reasonable actions as are necessary to ensure that Purchaser receives such economic benefits or other payments or funds.

8.16. Notices to Escrow Agent. Purchaser, Seller and Willbros shall provide the Escrow Agent with such notices, directions and instructions as are necessary for the Escrow Agent to fulfill its obligations set forth in the Escrow Agreement, in accordance with the provisions of this Agreement. Without limiting the foregoing, the Parties shall provide joint written instructions to the Escrow Agent in order to satisfy any indemnification for Damages owed to any Purchaser Indemnitee pursuant to Article IX.

8.17. Replacement of Surety Bonds. Within 30 days after the date hereof, Purchaser shall use commercially reasonable efforts to obtain replacement surety bonds for each of the existing surety bonds listed on Schedule 5.28. Seller will cooperate with Purchaser’s efforts to obtain such replacement bonds. After such 30-day period, Seller shall cancel any of such surety bonds that remain outstanding.

8.18. NYSIF Matter. At no time following the date hereof shall Purchaser, the Company or any other Affiliate of Purchaser pay any portion of a demand for payment of an amount alleged to be owed by the Company predating the Acquisition Date to New York State Insurance Fund (“NYSIF”) without first tendering such demand to Seller or Willbros.

(a) In the event that Seller is unable to effectively assign any Contract to Seller or one of its Affiliates in connection with the Stray Voltage Contribution prior to the Closing because of the inability to obtain any consent of a third party to such Contract, the parties hereto agree to, at the sole cost and expense of Seller and Willbros, (i) use their commercially reasonable efforts to obtain such third party consent as soon as practicable, and (ii) promptly after receipt of such third-party consent, cooperate in the post-Closing assignment of such Contract to Seller or one of its Affiliates; provided that the parties hereto acknowledge and agree that, as an alternative to assignment, any such customer Contract may alternatively be terminated and a new Contract entered into between such customer and an Affiliate of Seller. It is expressly understood and agreed that in no event shall Purchaser or any of its Affiliates (including the Company) have any obligation or other Liability to perform any services, or satisfy any other obligations, under any such Contract, and Seller and Willbros shall indemnify and hold harmless any Purchaser Indemnified Party from and against any and all Damages which any such Purchaser Indemnified Party may suffer, sustain or become subject to arising out of or in connection with any such Contract, including for any failure to perform any obligations or satisfy any other Liabilities under any such Contract, or for any of the matters contemplated by this Section 8.19.

(b) In the event that Seller is unable to effectively transfer the employment of any Mobile Contact/Stray Voltage Employee to Seller or one of its Affiliates in connection with the Stray Voltage Contribution prior to the Closing, the parties hereto agree that notwithstanding anything in this Agreement to the contrary (including Section 8.10) all compensation, benefits,

severance or other amounts owing or payable (including any related Taxes) in connection with such Mobile Contact/Stray Voltage Employee shall be at the sole cost and expense of Seller and Willbros, and Seller and Willbros shall indemnify and hold harmless any Purchaser Indemnified Party from and against any and all Damages which any such Purchaser Indemnified Party may suffer, sustain or become subject to arising out of or in connection with any failure to transfer of such employment prior to Closing, including any such compensation, benefits, severance or other amounts.

9.1. Survival. The representations, warranties, covenants and agreements contained in this Agreement shall be deemed and construed to be continuing representations, warranties, covenants and agreements and shall survive the Closing; provided, however, that the representations and warranties of all parties to this Agreement shall, except as set forth in the remainder of this Section 9.1, expire and be of no further force or effect on the date which is 18 months after the date hereof; provided further, that (a) the representations and warranties of (i) Purchaser set forth in Sections 4.1 (Organization and Standing), 4.2 (Authority; Authorization; Enforceability) and 4.5 (Brokers), and (ii) Seller set forth in Sections 5.1 (Incorporation, Organization and Standing), 5.4 (Authority; Authorization; Enforceability), 5.7 (Brokers), 5.8 (Capitalization of the Company) and 5.31 (Stray Voltage Contribution) shall survive indefinitely (the representations and warranties set forth in clauses (i) and (ii), collectively, the “Fundamental Representations”); (b) the representations and warranties of Seller set forth in Section 5.21 (Tax Matters) shall survive for the applicable statutory limitations period and (c) the representations and warranties of Seller set forth in Sections 5.11(b) (Undisclosed Liabilities) and 5.22 (Environmental, Health and Safety Matters) shall survive for three years after the date hereof; (d) the other provisions of this Agreement in which a time period is specified shall survive for the period specified therein; and (e) unless otherwise indicated, the covenants and agreements set forth in this Agreement shall survive the Closing until they have been fully performed or satisfied.

(a) By Seller. Subject to the terms and conditions set forth herein, from and after the Closing, Seller and Willbros shall jointly and severally indemnify and hold harmless the Purchaser Indemnitees from and against any Damages which any such Purchaser Indemnitee shall suffer, sustain or become subject to as a result of (i) the breach by Seller or Willbros of any of the representations and warranties made by Seller or Willbros in ARTICLE V, (ii) the breach by Seller or Willbros of any of its covenants or agreements contained in this Agreement, (iii) the matters set forth on Schedule 9.2(a)(iii) or (iv) the Stray Voltage Contribution (including any Taxes arising therefrom) or any Mobile Contact/Stray Voltage Assets And Liabilities.

(b) By Purchaser. Subject to the terms and conditions set forth herein, from and after the Closing, Purchaser shall indemnify and hold harmless the Seller Indemnitees from and against any Damages which any such Seller Indemnitee shall suffer, sustain or become subject to, as a result of (i) the breach by Purchaser of any of the representations and warranties made by Purchaser in ARTICLE IV, or (ii) the breach by Purchaser of any of its covenants or agreements contained in this Agreement.

(a) If any Purchaser Indemnitee desires to make a claim against Seller, or any Seller Indemnitee desires to make a claim against Purchaser (such Purchaser Indemnitee or Seller Indemnitee, an “Indemnified Person”) under Section 9.2 in connection with any action, suit, proceeding or demand at any time instituted against or made upon such Indemnified Person by any third party for which such Indemnified Person may seek indemnification hereunder other than a Tax Claim, the Power Survey Proceeding or Power Survey Patent Challenge (a “Third Party Claim”), whether or not subject to the Aggregate Deductible, such Indemnified Person shall promptly notify in writing, in the case of a claim under Section 9.2(a), Seller, or, in the case of a claim under Section 9.2(b), Purchaser (in each case, an “Indemnifying Party”), of such Third Party Claim and of the Indemnified Person’s claim of indemnification with respect thereto; provided, however, that the failure to so notify shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent that the Indemnifying Party is materially prejudiced by such failure (and then the Indemnifying Party shall only be released to the extent of Damages caused by such material prejudice). The Indemnifying Party shall have 30 days after receipt of such notice to notify such Indemnified Person if the applicable Indemnifying Party has elected to assume the defense of such Third Party Claim. If the applicable Indemnifying Party elects to assume the defense of such Third Party Claim, such Indemnifying Party shall be entitled at its own expense to conduct and control the defense and settlement of such Third Party Claim through counsel of its own choosing (reasonably acceptable to the applicable Indemnified Person) on behalf of the applicable Indemnified Person. If the Indemnifying Party fails to notify the Indemnified Person within 30 days after receipt of notice from the Indemnified Person of a Third Party Claim that the applicable Indemnifying Party has elected to assume the defense of such Third Party Claim, the Indemnified Person shall be entitled to assume the defense of such Third Party Claim at the expense of the applicable Indemnifying Party through counsel reasonably acceptable to the Indemnifying Party; provided, however, that the Indemnifying Party may not compromise or settle any Third Party Claim except as provided in Section 9.3(a).

(b) Any compromise, settlement or offer of settlement of any Third Party Claim of which the applicable Indemnifying Party has elected to assume the defense shall require the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld or delayed. Unless such consent is obtained, the applicable Indemnifying Party shall continue the defense of such claim; provided, however, that, if any Indemnified Person does not consent within 30 days of written notice to a bona fide offer of settlement that (A) the applicable Indemnifying Party wishes to accept and that, (B) contemplates the entry of a final, non-appealable order by a court of competent jurisdiction, or the binding and due execution and delivery of a settlement agreement, in each case in full satisfaction and resolution of the relevant Third Party Claim, (C) involves no payment of money by such Indemnified Person (including any other Purchaser Indemnified Person in the event such Indemnified Person is a Purchaser

Indemnified Party and including any Seller Indemnified Person in the event such Indemnified Person is a Seller Indemnified Person), (D) involves no admission of guilt or wrong-doing and no injunctive or non-monetary relief or other limitation on the future operation of the business of the Company, (E) is not conditioned upon, coupled with or otherwise related to or otherwise results in (or could reasonably be expected to result in) the waiver, termination, relinquishment, interpretation or amendment of any actual or asserted rights of such Indemnified Person (including any other Purchaser Indemnified Person in the event such Indemnified Person is a Purchaser Indemnified Party and including any Seller Indemnified Person in the event such Indemnified Person is a Seller Indemnified Person), and (F) expressly and unconditionally releases such Indemnified Person (including any other Purchaser Indemnified Person in the event such Indemnified Person is a Purchaser Indemnified Party and including any Seller Indemnified Person in the event such Indemnified Person is a Seller Indemnified Person) from all Liability in connection with such claim, the applicable Indemnifying Party may reassign the defense of such claim to such Indemnified Person, who may then continue to pursue the defense of such matter, free of any participation by the Indemnifying Party, at the sole cost and expense of such Indemnified Person. In the event of such an assignment, the obligation of the applicable Indemnifying Party with respect thereto shall not exceed the lesser of (i) the amount of the offer of settlement that such Indemnified Person so declined to accept or (ii) the aggregate Damages of the Indemnified Person with respect to such claim, including the costs of defense after reassignment of the defense of such claim to the Indemnified Person. Any voluntary and binding compromise, settlement or offer of settlement of any Third Party Claim of which the applicable Indemnifying Party has not elected to assume the defense or has reassigned the defense to the Indemnified Person shall require the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. If the Indemnifying Party shall assume the defense of any Third Party Claim, the Indemnified Person may participate, at its own expense, in the defense of such Third Party Claim; provided, however, that such Indemnified Person shall be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Party if (i) so requested by the Indemnifying Party to participate or (ii) in the reasonable opinion of counsel to the Indemnified Person, a conflict or potential conflict exists between the Indemnified Person and the Indemnifying Party that would make such separate representation advisable; and provided, further, that the Indemnifying Party shall not be required to pay for more than one such counsel (plus any appropriate local counsel) for all Indemnified Persons in connection with any Third Party Claim. So long as the Indemnified Person is conducting the defense of any Third Party Claim in accordance with the terms hereof, the Indemnifying Party agrees that the Indemnified Person shall have control over the conduct of such proceeding to the extent provided herein. The parties hereto agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any Third Party Claim, including the Indemnified Person providing the Indemnifying Party with access to the Indemnified Person’s records and personnel relating to any Third Party Claim during reasonable hours under the circumstances.

(c) If the Indemnifying Party makes any payment on any Third Party Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Person to any insurance benefits or other claims of the Indemnified Person with respect to such Third Party Claim.

(d) For the avoidance of doubt, to the extent that the provisions of this Section 9.3 conflict with the provisions of Section 8.11, the provisions of Section 8.11 shall control with respect to the Power Survey Proceeding and the Power Survey Patent Challenge.

(i) No claim for indemnification under (A) Section 9.2(a)(i) (other than any such claim relating to the breach by Seller of any Fundamental Representation or the representations and warranties of Seller set forth in Sections 5.5(c) (Noncontravention) 5.6 (Approvals), 5.11(b) (Undisclosed Liabilities), 5.21 (Tax Matters) and 5.22 (Environmental, Health and Safety Matters)) or (B) Section 9.2(b)(i) (other than any such claim relating to the breach by Purchaser of any Fundamental Representation) shall be made by any Purchaser Indemnitee or Seller Indemnitee, as applicable, with respect to any breach resulting in an individual item of Damages, or related items of Damages arising out of substantially similar facts and circumstances, unless and until the amount of such Damages suffered by the Company and/or any other Purchaser Indemnitee or Seller and/or any other Seller Indemnitee, as applicable, exceeds $100,000, at which point a claim may be made for the entire amount of such Damages; and

(ii) No claim for indemnification under (A) Section 9.2(a)(i) (other than any such claim relating to the breach by Seller of any Fundamental Representation or the representations and warranties of Seller set forth in Sections 5.5(c) (Noncontravention), 5.6 (Approvals), 5.21 (Tax Matters) and 5.22 (Environmental, Health and Safety Matters)) or (B) Section 9.2(b)(i) (other than any such claim relating to the breach by Purchaser of any Fundamental Representation) shall be made by any Purchaser Indemnitee or Seller Indemnitee, as applicable, unless and until the aggregate amount of all Damages for which Purchaser Indemnitees or Seller Indemnitees, as applicable, are otherwise entitled to indemnification under this ARTICLE IX exceeds an amount equal to one percent of the Enterprise Value (the “Aggregate Deductible”), and then only to the extent the aggregate amount of all such Damages exceeds the Aggregate Deductible.

(b) Cap. Subject to the other limitations of this Section 9.4, the aggregate amount of all Damages payable to (i) all Purchaser Indemnitees with respect to all claims for indemnification under Section 9.2(a)(i) (other than any such claim relating to the breach by Seller of any Fundamental Representation) or the representations and warranties of Seller set forth in Sections 5.21 (Tax Matters) and 5.22 (Environmental, Health and Safety Matters)) and (ii) all Seller Indemnitees with respect to all claims for indemnification under Section 9.2(b)(i) (other than any such claim relating to the breach

by Purchaser of any Fundamental Representation), in each case, shall not exceed an amount equal to 10 percent of the Enterprise Value (the “Cap”). Any Damages owed to any Purchaser Indemnitee shall (i) first be satisfied out of any remaining funds in the Escrow Account and (ii) then be satisfied by Seller and Willbros on a joint and several basis, in each case, subject to the Cap. In no event shall (A) Seller’s obligations with respect to the indemnity provisions of Section 9.2(a) exceed an aggregate amount equal to the Aggregate Purchase Price or (B) Purchaser’s obligations with respect to the indemnity provisions of Section 9.2(b) exceed an aggregate amount equal to the Aggregate Purchase Price.

(c) Time Limit. No Person shall be liable for any claim for indemnification hereunder, whether or not as a result of a Third Party Claim, unless written notice of a claim for indemnification is delivered by the Person seeking indemnification to the Person from whom indemnification is sought with respect to any such breach before the applicable Survival Date (in which case such indemnification obligation shall survive the time at which it would otherwise terminate pursuant to this ARTICLE IX regardless of when any Damages in respect thereof may actually be incurred). All notices given pursuant hereto shall set forth with reasonable specificity the basis for such claim for indemnification.

(d) Insurance; Other Indemnification. The amount of any Damages subject to indemnification hereunder shall be calculated net of any amounts actually recovered by Purchaser or the Company under insurance policies (net of any deductibles or expenses incurred in connection with such recovery or increased premiums as a result of such recovery or the loss or event giving rise thereto) or other collateral sources (such as contractual indemnities or contributions of any Person which are contained outside this Agreement), and the parties agree to use reasonable efforts to obtain such recoveries.

(e) Mitigation. Purchaser shall take and shall cause the Company and any other Purchaser Indemnitees to take commercially reasonable steps to mitigate any Damages upon becoming aware of any event which would reasonably be expected to, or does, give rise thereto; provided, that no obligation to mitigate under this Section 9.4(e) shall require the incurrence of out of pocket costs by a Purchaser Indemnitee to remedy the breach or other matter which gives rise to the Damages. Notwithstanding anything herein to the contrary, Seller shall not be liable for any Damages to the extent (but only to the extent) that the Purchaser Indemnitees fail to take commercially reasonable action to mitigate any such Damages reasonably promptly after obtaining actual knowledge of the event giving rise to such Damages.

(f) No Special Damages. Notwithstanding any provision of this Agreement to the contrary, no Person shall be liable to any other Person for any consequential, incidental, indirect, special, exemplary, or punitive damages of such other Person, in each case relating to the breach or alleged breach of any representation, warranty, covenant or agreement in this Agreement or related hereto; provided, however, that nothing in the foregoing proviso shall prevent a Person from recovering (a) any Damages (other than punitive or exemplary damages) that are reasonably foreseeable or (b) any Damages, including punitive or exemplary Damages, incurred by such Person in connection with a Third Party Claim.

(g) Materiality. For purposes of the indemnification obligations under this Article IX, all of the representations and warranties set forth in this Agreement that are qualified as to “material,” “materiality,” “material respects,” “Material Adverse Effect,” or words of similar import or effect shall be deemed to have been made without any such qualification for purposes of (i) determining the amount of Damages resulting from, arising out of or relating to such breach of any representation or warranty and (ii) determining whether a breach of any such representation or warranty (other than the representations and warranties in Sections 5.21 (Tax Matters) and 5.22 (Environmental, Health and Safety Matters)) has occurred.

(h) Treatment of Indemnification Payments. Any indemnification payments made by Purchaser or Seller pursuant to this ARTICLE IX shall be treated by all parties as an adjustment to the Aggregate Purchase Price hereunder.

9.5. Limitation of Remedies. The rights of the parties for indemnification relating to this Agreement and the transactions contemplated hereby shall be strictly limited to those respectively contained in this ARTICLE IX, Section 8.11, Section 8.19, Section 10.2 and Section 10.9 and, subject to Section 8.14(e), Section 9.7 and the last sentence of this Section 9.5, such indemnification rights shall be the sole and exclusive remedies of the parties after the date hereof with respect to any matter in any way relating to this Agreement or arising in connection herewith. To the maximum extent permitted by Law, Purchaser hereby waives and shall cause its Affiliates to waive all other rights and remedies with respect to any such matter, whether under any Laws (including any right or remedy under CERCLA or any other Environmental, Health and Safety Law), at common law or otherwise, including for rescission. Except as provided by this ARTICLE IX, Section 8.11, Section 8.14(e), Section 8.19, Section 9.7, Section 10.2 and Section 10.9, no action, suit, claim, proceeding or remedy shall be brought or maintained after the date hereof by Purchaser or any of its Affiliates, including any other Purchaser Indemnitees, successors or permitted assigns against Seller or any of its Affiliates, and no recourse shall be brought or granted against Seller or any of its Affiliates, by virtue of or based upon any alleged misstatement or omission respecting an inaccuracy in or breach of any of the representations, warranties, covenants or agreements of Seller set forth or contained in this Agreement; provided, however, that nothing in this Agreement shall be deemed to prevent or restrict the bringing or maintenance of any such claim or action, or the granting of any such remedy, to the extent that the same shall have been the result of intentional fraud by any such Person (and in the event of intentional fraud, recourse shall only extend to those Persons committing intentional fraud).

(a) The release of amounts in the Escrow Account shall be subject to the terms of this Agreement and the Escrow Agreement.

(b) On the earlier of (1) the receipt by Purchaser of full audited financial statements for the Company for the fiscal year ended December 31, 2015 or (2) March 31,

2016, Seller and Purchaser shall execute a joint instruction directing the Escrow Agent to release promptly, but no later than two Business Days following receipt of such instruction, to Seller from the Escrow Account an amount equal to (i) the balance of the Escrow Account then remaining (including any accrued interest attributable thereto), minus the amounts of any unresolved claims of the Purchaser Indemnitees for indemnification properly asserted in accordance with the terms and limitations set forth in this Agreement and the Escrow Agreement (such claims being hereinafter referred to as “Pending Claims”), minus an amount equal to $2,000,000.

(c) On the date which is 18 months after the date hereof (the “Release Date”), Seller and Purchaser shall execute a joint instruction directing the Escrow Agent to release promptly, but no later than two Business Days following receipt of such instruction, to Seller the balance of the Escrow Account as of the Release Date, minus the amounts of any Pending Claims.

(d) If at any time between the date hereof and the Release Date, any Pending Claims by a Purchaser Indemnitee in respect of which amounts may have been retained in the Escrow Account pursuant to Section 9.6(c) are finally resolved by either mutual written agreement of Seller and Purchaser or by a final non-appealable decision of a court of competent jurisdiction or similar judicial entity (such Pending Claims being hereinafter referred to as “Resolved Claims”), the Escrow Agent shall disburse promptly, but no later than two Business Days following receipt of such mutual written agreement or final court determination, to the relevant Purchaser Indemnitees, the aggregate amount, if any, of such Resolved Claims (or, if less, the remaining funds in the Escrow Account) determined to be owing to such Purchaser Indemnitees.

(e) After the Release Date, at such time as any Pending Claims in respect of which amounts may have been retained in the Escrow Account pursuant to Section 9.6(c) become Resolved Claims, the Escrow Agent shall disburse promptly, but no later than two Business Days following receipt of such final determination, (i) to the relevant Purchaser Indemnitees, the aggregate amount, if any, of such Resolved Claims (or, if less, the remaining funds in the Escrow Account) determined to be owing to such Purchaser Indemnitees, and (ii) to Seller, the amount, if any, of such Resolved Claims that was not disbursed to the Purchaser Indemnitees in accordance with such final determination and the Escrow Agreement but not to exceed the balance of the Escrow Account as of such date minus the aggregate amount of all Pending Claims in respect of which amounts may have been retained in the Escrow Account pursuant to Section 9.6(c) as of such date.

9.7. Specific Performance. The parties hereto acknowledge and agree that the parties would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by either party hereto could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which Purchaser or Seller, as the case may be, may be entitled, at law or in equity, such party shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without the necessity of posting any bond or other undertaking.

9.8. Knowledge of Purchaser. The representations and warranties of Seller and Willbros shall not be affected or deemed waived by reason of any investigation made (or not made) by or on behalf of Purchaser, or by reason of the fact that Purchaser or any of their advisors, agents, consultants or representatives knew or should have known that any such representation and warranty is or might be inaccurate or untrue. Each of Seller and Willbros hereby acknowledges that, regardless of any investigation made (or not made) by or on behalf of Purchaser, and regardless of the results of any such investigation, Purchaser has entered into this Agreement in express reliance upon the representations and warranties of Seller and Willbros set forth in this Agreement and the other Transaction Documents.

(a) Seller shall prepare and cause to be filed all Returns of the Company required to be filed for all Tax Periods ending on or before the date hereof. Seller shall deliver to Purchaser for its review a draft of each such Return of the Company to be filed after the date hereof not fewer than 30 days before the deadline for filing such Return, including extensions (for the avoidance of doubt, Returns of Seller’s parent entity shall not be subject to the delivery and review requirements of the foregoing sentence). Purchaser shall notify Seller in writing if it objects to any portion of a draft Return within 15 days after the draft Return is delivered to Purchaser. If Seller does not receive a written objection (specifying in detail the nature of such objection) by the end of such 15-day period, Seller shall file the Return and such Return shall be deemed final and binding as between the parties. If Purchaser notifies Seller that it objects to any portion of the draft Return (specifying in detail the nature of such objection) on or before the end of such 15-day period, Purchaser and Seller shall attempt to mutually resolve any disagreements in good faith regarding such draft Return. Any disagreements regarding the draft Returns that are not resolved within an additional 10-day period by Seller and Purchaser shall be resolved by the Independent Accounting Firm, whose decision shall be final and whose fees shall be shared equally by Seller and Purchaser. The Returns that are subject to any disagreement shall not be filed until such disagreement is resolved; provided, that, if such Returns must be filed in order to avoid a penalty, such Returns may be filed as prepared (with any changes to which Seller and Purchaser agree prior to the date of filing reflected therein), and, if further changes are agreed upon or required by the Independent Accounting Firm, then Seller shall amend such Returns promptly to reflect such changes. Purchaser shall cause the Company to cooperate fully and promptly in connection with Seller’s preparation of and the filing of all Returns under this Section 10.1(a).

(b) Purchaser shall prepare (or cause to be prepared) and timely file (or cause to be timely filed) all Returns of the Company for any Tax period that begins before the date hereof and ends after the date hereof (a “Straddle Period”). Purchaser shall deliver to Seller for its review a draft of each such Return of the Company (i) not fewer than 30 days before the deadline for filing such Return for income Taxes, including extensions, and (ii) not fewer than 15 days before the deadline for filing such Return for all other

Taxes, including extensions. Seller shall notify Purchaser in writing if it objects to any portion of a draft Return (i) within 15 days after the draft Return for income Taxes is delivered to Seller and (ii) within 10 days after the draft Return for all other Taxes is delivered to Seller. If Purchaser does not receive a written objection by the end of such 15-day or 10-day period, respectively, Purchaser shall file the Return. If Seller notifies Purchaser that it objects to any portion of the draft Return on or before the end of such 15-day or 10-day period, respectively, Purchaser and Seller shall attempt to mutually resolve any disagreements in good faith regarding such draft Return. Any disagreements regarding the draft Returns that are not resolved within an additional (i) 10-day period for a Return for income Taxes and (ii) 5-day period for a Return for all other Taxes by Seller and Purchaser shall be resolved by the Independent Accounting Firm, whose decision shall be final and whose fees shall be shared equally by Seller and Purchaser. The Returns that are subject to any disagreement shall not be filed until such disagreement is resolved; provided, that, if such Returns must be filed in order to avoid a penalty, such Returns may be filed as prepared (with any changes to which Seller and Purchaser agree prior to the date of filing reflected therein), and, if further changes are agreed upon or required by the Independent Accounting Firm, then Purchaser shall amend such Returns promptly to reflect such changes.

10.2. Liability for Taxes. Seller shall be responsible for (and shall indemnify and hold harmless Purchaser and its Affiliates from and against all Damages relating to) all Taxes of the Company for any Pre-Closing Tax Period and for Seller’s portion (as determined under Section 10.3) of all Taxes of the Company for any Straddle Period to the extent such Taxes are not satisfied by Seller or any of its Affiliates (other than the Company); provided that for purposes of this Section 10.2, Taxes shall include the amount of Taxes that would have been paid but for the application of any credit or net operating loss or capital loss attributable to any Post-Closing Tax Period. Purchaser shall be responsible for (and shall indemnify and hold harmless Seller and its Affiliates from and against all Damages relating to) all Taxes of the Company for any Post-Closing Tax Period and for its portion (as determined under Section 10.3) of all Taxes of the Company for any Straddle Period.

(a) With respect to any Straddle Period, the Taxes of the Company attributable to such Straddle Period shall be apportioned between the portion of the Straddle Period that begins on the first day of the Straddle Period and ends on the date hereof (the “Pre-Closing Straddle Period”), which portion shall be the responsibility of Seller (to the extent provided in Section 10.2), and all other Taxes attributable to the operations or assets of the Company for the Straddle Period shall be the responsibility of Purchaser.

(b) In the case of income Taxes, sales and use Taxes, employment Taxes, and Taxes based on gross or net receipts or payments, the portion of the Tax allocated to the Pre-Closing Straddle Period shall equal the amount that would be payable if the Straddle Period ended on the date hereof by means of closing the books and records of the Company as of the date hereof; provided, that all permitted allowances, exemptions and deductions that are normally computed on the basis of an entire year or period (such as

depreciation and amortization deductions) shall accrue on a daily basis and shall be allocated between the Pre-Closing Straddle Period and the portion of the Straddle Period that begins on the day immediately following the date hereof and ends on the last day of the Straddle Period (the “Post-Closing Straddle Period”) in proportion to the number of days in each such period.

(c) In the case of Taxes not described in Section 10.3(b), the portion of the Tax allocated to the Pre-Closing Straddle Period shall equal the amount of Tax for the entire Straddle Period multiplied by the ratio of the number of days during the Pre-Closing Straddle Period to the number of days during the entire Straddle Period.

(d) Notwithstanding the foregoing provisions of this Section 10.3 and except as required by Law, any deductions for income Tax purposes that are attributable to the payment of bonuses, other compensation, the write off of capitalized financing fees and any other deductions that arise on the date hereof as a result of the transaction contemplated by this Agreement, shall be taken into account in the Pre-Closing Straddle Period.

(e) This Section 10.3 shall apply mutatis mutandis to any Tax refunds or Tax credits to which the Company may be entitled.

10.4. Cooperation. In connection with the preparation of Returns, audit examinations, and any administrative or judicial proceedings relating to the Taxes imposed on the Company for all Pre-Closing Tax Periods, all Straddle Periods and all Post-Closing Tax Periods, Purchaser, the Company, on the one hand, and Seller, on the other hand, shall cooperate fully with each other, including furnishing or making available during normal business hours records, personnel (as reasonably required), books of account, powers of attorney and/or other materials necessary or helpful for the preparation of such Returns, the conduct of audit examinations or the defense of claims by Tax Authorities as to the imposition of Taxes. Purchaser shall provide Seller, and Seller shall provide Purchaser, with the information that each is respectively required to report under section 6043A of the Code or any other applicable Tax rule. After the Closing, Seller may deliver to Purchaser certain U.S. Tax information requests in a similar manner provided to the Company in previous years in order to comply with Seller’s U.S. Tax and other reporting obligations and Purchaser shall use reasonable efforts to promptly complete such information requests as is required for Seller to comply with Seller’s U.S. Tax or other reporting obligations.

(a) If any Tax Authority issues to Purchaser or the Company (i) a notice of its intent to audit, examine or conduct a proceeding with respect to Taxes or Returns of the Company for any Pre-Closing Tax Period or (ii) a notice of deficiency, notice of reassessment, proposed adjustment, assertion of claim or demand concerning Taxes or Returns attributable to the operations or assets of the Company for any Pre-Closing Tax Period (each, a “Tax Claim”), Purchaser shall notify Seller of the receipt of such communication from the Tax Authority and shall deliver a copy of any such written communication to Seller within 10 Business Days after receiving such Tax Claim. The failure of Purchaser to give timely notice hereunder shall not affect Purchaser’s right to indemnification hereunder, except to the extent such delay or failure prejudices Seller.

(b) Purchaser and the Company shall control any proceeding relating to any Tax Claim with respect to Taxes attributable to the operations or assets of or Returns of the Company (a “Tax Contest”); provided, that (i) Seller shall have the right to participate in any such Tax Contest to the extent it relates to Taxes or a Return for a Pre-Closing Tax Period and in such case Purchaser and the Company shall promptly provide Seller with copies of all written communications relating to the Tax Contest, (ii) Purchaser shall keep Seller informed on a timely basis regarding the progress of any Tax Contest and consult with Seller with respect to any issue relating to such Tax Contest that could affect Seller, and (iii) Purchaser and the Company shall not settle or otherwise resolve any Tax Contest (or any issue raised in any Tax Contest) if such settlement or other resolution relates to Taxes for which Seller is liable under this Agreement without the prior written consent of Seller (which shall not be unreasonably withheld or delayed).

(c) At the request of Seller, Purchaser or the Company, as applicable, shall settle any issue related to Taxes for any Pre-Closing Tax Period on terms acceptable to Seller and the applicable Tax Authority; provided, that (i) Seller shall pay when due all Taxes (and other amounts) for which Seller is liable under this Agreement as a result of such settlement, and (ii) the settlement would not result in Purchaser or the Company paying any increased Taxes for which Seller is not required to fully indemnify Purchaser or the Company under this Agreement.

10.6. Amended Returns. Purchaser shall not file or cause to be filed any amended Returns covering any period or adjusting any Taxes for a period that includes any Pre-Closing Tax Period without the prior written consent of Seller, which consent may not be unreasonably withheld or delayed. Purchaser shall not take and shall not cause or permit the Company to take any action in breach of Sections 10.1, 10.4, 10.5 or 10.6 that could increase the liability of Seller for Taxes under this Agreement without the prior written consent of Seller, which consent shall not be unreasonably withheld or delayed.

10.7. Tax Refunds. Purchaser and the Company shall cooperate with Seller in obtaining any Tax refunds or Tax credits for any Pre-Closing Tax Periods. Any refunds, and, in the case of a credit, that actually reduces the cash Taxes required to be paid by Purchaser or the Company for Taxes of the Company for Post-Closing Tax Periods shall be for the account of Seller; provided, however, that such refunds or credits shall not include any refunds or credits attributable to the carryback of a tax attribute arising in a Post-Closing Tax Period. If Purchaser or the Company receives a refund or credit for Taxes that is for the account of Seller, Purchaser shall pay the full amount of the refund or the amount of Tax savings related to any such credit to Seller within 15 Business Days of the receipt thereof, net of any out-of-pocket costs or expenses (including Tax) incurred in seeking or securing such refund or credit. Notwithstanding the foregoing, if any refund or credit giving rise to payment to Seller pursuant to this Section 10.7 is subsequently disallowed or reduced, Seller shall indemnify and hold harmless Purchaser and the Company for and against any Tax, or other out-of-pocket cost to them, that is attributable to such reduction or disallowance (plus any related penalties or interest imposed by the relevant Tax Authority with respect to such amounts).

10.8. Tax Elections; Post-Closing Actions. Neither Purchaser nor any of its Affiliates shall (i) make an election under section 338 of the Code with respect to the transactions contemplated hereby or (ii) take any action on the date hereof after the Closing that increases Seller’s obligations under Sections 10.2 or 9.2(a). Seller shall have no Liability with respect to any Taxes or losses resulting by reason of such election or action made or deemed to be made by Purchaser or any of its Affiliates after the Closing.

10.9. Other Taxes. Purchaser, on the one hand, and Seller and Willbros, on the other hand, shall each be 50% liable for and shall each pay (and shall indemnify and hold harmless the other and its Affiliates from and against all Damages relating to) 50% of all sales, use, stamp, documentary, filing, recording, transfer or similar fees or Taxes or governmental charges (together with any interest or penalty, addition to Tax or additional amount imposed) as levied by any Authority in connection with the purchase and sale of the Units (including any deemed sale of the assets of Utility Services) contemplated by this Agreement (“Transfer Taxes”); provided, that notwithstanding the foregoing, Seller and Willbros shall be solely responsible for, and shall pay (and shall indemnify and hold harmless Purchaser and its Affiliates, including the Company, from and against all Damages relating to) 100% of any Transfer Taxes related to or arising out of the Stray Voltage Contribution. For the avoidance of doubt, this Section 10.9 shall not apply to any income taxes or other taxes imposed on or with respect to income, such as franchise taxes.

10.10. Tax Sharing or Arrangements. Any and all existing Tax sharing, allocation or like agreements or arrangements of the Company have been terminated prior to the Closing.

12.1. Notices. All notices, requests, demands, claims and other communications required or permitted to be given hereunder shall be in writing and shall be given by: (a) personal delivery (effective upon delivery), (b) facsimile (effective on the next Business Day after transmission), (c) recognized overnight delivery service (effective on the next Business Day after delivery to the service), or (d) registered or certified mail, return receipt requested and postage prepaid (effective on the third Business Day after being so mailed), in each case addressed to the intended recipient as set forth below:

12.2. Entire Agreement. This Agreement and the other Transaction Documents constitute the entire agreement between the parties hereto with respect to the transactions contemplated hereby and supersede all prior agreements, understandings, negotiations and discussions, both written and oral, among the parties hereto with respect thereto. Neither the duties nor obligations of either party hereto, nor the rights of either party hereto, shall be expanded beyond the terms of this Agreement on the basis of any legal or equitable principle or on any other basis whatsoever. Neither any legal or equitable principle nor any implied obligation of good faith or fair dealing nor any other matter requires either party hereto to incur, suffer or perform any act, condition or obligation contrary to the terms of this Agreement, whether or not existing and whether foreseeable or unforeseeable. Each of the parties hereto acknowledges that it would be unfair, and that it does not intend, to increase any of the obligations of the other party under this Agreement on the basis of any implied obligation or otherwise.

12.3. Amendment and Waiver. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by Seller and Purchaser, or in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by either party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

12.4. Benefits; Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Except as set forth below, neither this Agreement nor the obligations of either party hereunder shall be assignable or transferable by such party without the prior written consent of the other parties hereto.

12.5. No Third Party Beneficiary. Nothing in this Agreement, express or implied, is intended to confer upon any Person other than Purchaser, Purchaser Indemnitees, the Company, Seller, Seller Indemnitees and their respective successors, heirs, personal representatives and permitted assigns, any rights or remedies under or by reason of this Agreement.

12.6. Severability. It is the desire and intent of the parties hereto that the provisions of this Agreement be enforced to the fullest extent permissible under the Laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

12.7. Expenses. Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated by this Agreement are consummated, the parties shall bear their own respective expenses (including all compensation and expenses of their own counsel, financial advisors, consultants, actuaries and accountants) incurred in connection with the preparation, execution and consummation of this Agreement and of the transactions contemplated hereby, provided, however, that Purchaser shall be responsible for all filing and other similar fees payable in connection with any filings or submissions under the HSR Act.

12.8. Counterparts and Delivery. This Agreement may be executed in any number of counterparts and by the several parties hereto in separate counterparts, and delivered by facsimile or other means of electronic transmission, each of which shall be deemed to be one and the same instrument and an original document.

12.9. Governing Law; Waiver of Jury Trial. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICTING PROVISION OR RULE (WHETHER OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF DELAWARE TO BE APPLIED. IN FURTHERANCE OF THE FOREGOING, THE INTERNAL LAW OF THE STATE OF DELAWARE WILL CONTROL THE INTERPRETATION AND CONSTRUCTION OF THIS AGREEMENT, EVEN IF UNDER SUCH JURISDICTION’S CHOICE OF LAW OR CONFLICT OF LAW ANALYSIS, THE SUBSTANTIVE LAW OF SOME OTHER JURISDICTION WOULD ORDINARILY APPLY. EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT SUCH PARTY MAY LEGALLY AND EFFECTIVELY DO SO, TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING ARISING HEREUNDER.

12.10. Disclosure Schedules. A disclosure made by Seller in any Section of this Agreement or any of the Schedules (or subparts thereof) that reasonably informs Purchaser of information with respect to another Section of this Agreement or any other Schedule (or subparts thereof) in order to avoid a misrepresentation thereunder shall be deemed, for all purposes of this Agreement, to have been made with respect to all such other Sections of this Agreement and all such other Schedules (or subparts thereof), notwithstanding any cross-references (which are included solely as a matter of convenience) or lack of a Schedule reference in any representation or warranty. Information reflected in the Schedules is not necessarily limited to matters required by this Agreement to be reflected in the Schedules. Such additional information is set forth for informational purposes and does not necessarily include other matters of a similar nature. Disclosure of such additional information shall not be deemed to constitute an acknowledgment that such information is required to be disclosed and disclosure of such information shall not be deemed to enlarge or enhance any of the representations or warranties in this Agreement or otherwise alter in any way the terms of this Agreement. Inclusion of information in the Schedules shall not be construed as an admission that such information is material to the business, assets, liabilities, financial position, operations or results of operations of the Company.

12.11. Waiver and Release. Notwithstanding anything to the contrary in this Agreement, from and after Closing, the Company shall not have any liability to Seller or its Affiliates in respect of, and none of Seller nor its Affiliates shall have (and Seller hereby, on its own behalf and on behalf of its Affiliates irrevocably and unconditionally releases, waives and agrees not to assert) any right (whether at law or in equity, based in contract, tort or otherwise and including any claim for indemnification, contribution or other relief) against, or recourse to, Purchaser and its Affiliates (including the Company) in respect of any breach by the Company occurring at or prior to the Closing of any provision of this Agreement (including any inaccuracy or untruth of any representation or warranty of, or with respect to, the Company y). Except for the Contracts listed on Schedule 12.11, effective as of the Closing, Seller, on behalf of itself and each of its Affiliates, successors and assigns (collectively, the “Releasing Parties”): (i) releases, acquits and forever discharges the Company and each of its Affiliates, successors and assigns (collectively, the “Purchaser Released Parties”) from any and all claims, demands, damages, actions, causes of action, rights, costs, losses, expenses, compensation or suits in equity, of whatsoever kind or nature, in contract or in tort, at law or in equity, that such Releasing Party might have in each case arising out of anything done, omitted, suffered or allowed to be done by any Purchaser Released Party, including pursuant to any account, arrangement, agreement, understanding, representation or promise by, between or among any Purchaser Released Party, on the one hand, and any Releasing Party, on the other hand, in each case whether heretofore or hereafter accrued or unaccrued and whether foreseen or unforeseen or known or unknown, including any claim relating to the valuation or prospects of the Business or any claim relating to any inducement to enter into this Agreement, in each case to the extent related to matters or events occurring prior to the Closing (collectively, the “Released Matters”), provided that any claims or rights of Seller which arise from this Agreement or the other Transaction Documents from and after the Closing, including any rights to indemnification pursuant to Article IX, shall not be Released Matters; (ii) agrees never to commence or

participate in a manner adverse to any Purchaser Released Party in any legal action or other proceeding based in whole or in part upon any Released Matters; and (iii) acknowledges and agrees that it has provided this release, on behalf of itself and the other Releasing Parties, voluntarily, with the intention of fully and finally extinguishing all Released Matters.

IN WITNESS WHEREOF, the parties hereto have each executed and delivered this Agreement as of the day and year first above written.
