For the purposes of preparing the Closing Statement, the Purchaser shall use the Insurance Claims Accrual as set forth in the Estimated Closing Statement.

(b) Disputes. Subject to this Section 2.06(b), the Closing Statement delivered by the Purchaser to Quanta shall be final, conclusive and binding on the parties hereto.

(i) Quanta may dispute any amounts reflected on the Closing Statement other than the Insurance Claims Accrual, but only on the basis that the amounts reflected on the Closing Statement (A) were not arrived at in accordance with GAAP applied on a basis consistent with the Audited Financial Statements and the preparation of the Example Statement of Net Working Capital, or (B) were arrived at

based on factual, mathematical or clerical error or differences in accounting judgments or estimates; provided, however, that Quanta shall have notified the Purchaser in writing of each disputed item, specifying the estimated amount thereof in dispute and setting forth, in reasonable detail, the basis for such dispute, within 20 Business Days of the Purchaser’s delivery of the Closing Statement to Quanta. During such 20 Business Days, to the extent reasonably requested by Quanta, the Purchaser will make available to Quanta and its auditors and advisors all records and work papers used in preparing the Closing Statement, including the Net Working Capital Adjustment Amount, and provide reasonable access to members of its accounting and financial staff in connection with Quanta’s review thereof. In the event that Quanta delivers a notice of dispute as set forth above, the Sellers’ Accountants and the Purchaser’s Accountants shall attempt to reconcile their differences, and any resolution by them as to any disputed amounts shall be final, conclusive and binding on the parties hereto. If the Sellers’ Accountants and the Purchaser’s Accountants are unable to reach a resolution with such effect within 20 Business Days after the receipt by the Purchaser of Quanta’s written notice of dispute, the Sellers’ Accountants and the Purchaser’s Accountants shall submit the items remaining in dispute for resolution to Ernst & Young LLP (or, if such firm shall decline or is unable to act or is not, at the time of such submission, independent of the Sellers, Dycom and the Purchaser, to another independent accounting firm of international reputation mutually acceptable to the Sellers and the Purchaser) (either Ernst & Young LLP or such other accounting firm being referred to herein as the “Independent Accounting Firm”). The Purchaser and Quanta shall use all commercially reasonable efforts to cause the Independent Accounting Firm to, within 30 days after such submission, determine what it believes in its professional judgment to be the most accurate calculation of the remaining disputed items in accordance with the terms of this Agreement and report to Quanta and the Purchaser upon such remaining disputed items, and such report shall be final, conclusive and binding on the Sellers, Dycom and the Purchaser. With respect to each disputed item, such determination of the Independent Account Firm shall not be in excess of the higher, nor less than the lower, of the amounts advocated by the Purchaser in the Closing Statement or Quanta in the notice of dispute. The Purchaser and Quanta shall cooperate with the Independent Accounting Firm and shall provide the Independent Accounting Firm access to such books and records as it may request to make its determinations and report. The fees and disbursements of the Independent Accounting Firm shall be allocated between the Sellers and the Purchaser in the same proportion that the aggregate amount of such remaining disputed items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by each such party (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining disputed items so submitted.

(ii) In acting under this Agreement, the Sellers’ Accountants, the Purchaser’s Accountants and the Independent Accounting Firm shall be entitled to the privileges and immunities of arbitrators.

(c) Purchase Price Adjustment. The Closing Statement shall be deemed final for the purposes of this Section 2.06 upon the earliest of (x) the failure of Quanta to notify the Purchaser of a dispute within 20 Business Days of the Purchaser’s delivery of the Closing Statement to Quanta, (y) the resolution of all disputes, pursuant to Section 2.06(b)(i), by the

Sellers’ Accountants and the Purchaser’s Accountants, and (z) the resolution of all disputes, pursuant to Section 2.06(b)(i), by the Independent Accounting Firm. Within three Business Days of the Closing Statement being deemed final, a Purchase Price adjustment shall be made as follows:

(i) If the Actual Adjustment Amount is a positive number, then the Purchaser shall pay to Quanta (on behalf of the Sellers) an amount equal to such positive amount, net of applicable withholding Taxes, if any, by wire transfer or delivery of immediately available funds.

(ii) If the Actual Adjustment Amount is a negative number, then Quanta (on behalf of the Sellers) shall pay to the Purchaser an amount equal to the absolute value of such negative number, by wire transfer or delivery of immediately available funds.

(d) Interest on Payments. Any payments required to be made by Quanta or the Purchaser pursuant to Section 2.06(c) shall bear interest for each day from the Closing Date through the date of payment at the rate stated in the “Money Rates” section of The Wall Street Journal published as the one month London Interbank Offered Rate for such day (or if such day is not a day on which such rate is published, for the preceding day on which such rate was published) plus 200 basis points and based on a year of 360 days and actual days elapsed.

SECTION 3.21 Employee Benefit Matters.

(a) Plans and Material Documents. Section 3.21(a) of the Disclosure Schedule lists (i) all employee benefit plans (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) and all bonus, stock option, stock purchase, restricted stock, incentive, deferred compensation, retiree medical or life insurance, supplemental retirement, severance or other benefit plans, programs or arrangements, and all employment, termination, severance or other contracts or agreements, whether legally enforceable or not, to which any Acquired Company or Subsidiary is a party, with respect to which any Acquired Company or Subsidiary has any obligation or which are maintained, contributed to or sponsored by any Acquired Company or Subsidiary for the benefit of any current or former employee, officer or director of any Acquired Company or Subsidiary, (ii) each

employee benefit plan for which any Acquired Company or Subsidiary could incur liability under Section 4069 of ERISA in the event such plan has been or were to be terminated, (iii) any plan in respect of which any Acquired Company or Subsidiary could incur liability under Section 4212(c) of ERISA, and (iv) any contracts, arrangements or understandings between the Sellers or any of their Affiliates and any employee of any Acquired Company or Subsidiary, including any contracts, arrangements or understandings relating to the sale of the Acquired Companies (collectively, the “Plans”).

No Acquired Company or Subsidiary has any express or implied commitment, whether legally enforceable or not, (I) to create, incur liability with respect to, or cause to exist, any other employee benefit plan, program or arrangement, (II) to enter into any contract or agreement to provide compensation or benefits to any individual, or (III) to modify, change or terminate any Plan, other than with respect to a modification, change or termination required by ERISA or the Code.

Except as listed in Section 3.21(b) of the Disclosure Schedule, none of the Plans is a multiemployer plan (within the meaning of Section 3(37) or 4001(a)(3) of ERISA) (a “Multiemployer Plan”) or a single employer pension plan (within the meaning of Section 4001(a)(15) of ERISA) for which any Acquired Company or any Subsidiary could incur liability under Section 4063 or 4064 of ERISA (a “Multiple Employer Plan”). None of the Plans provides for or promises retiree medical, disability or life insurance benefits to any current or former employee, officer or director of any Acquired Company or Subsidiary other than as required under Section 4980B of the Code or any similar applicable state or local law. Each of the Plans is subject only to the Laws of the United States or a political subdivision thereof.

Each Acquired Company and Subsidiary has performed all material obligations required to be performed by it under, is not in any material respect in default under or in violation of, and has no knowledge of any default or violation by any party to, any Plan. No Action is pending or, to the Sellers’ Knowledge, threatened with respect to any Plan (other than claims for benefits in the ordinary course) and no fact or event exists that could give rise to any such Action.

Except with respect to any Plan that is a Multiemployer Plan, each Plan that is intended to be qualified under Section 401(a) of the Code or Section 401(k) of the Code has received a favorable determination letter from the IRS that it is so qualified or has received an opinion or advisory letter from the IRS on which it may rely, and each trust established in connection with any Plan that is intended to be exempt from federal income taxation under Section 501(a) of the Code has received a determination letter from the IRS that it is so exempt or has received an opinion or advisory letter from the IRS on which it may rely, and no fact or event has occurred since the date of such determination, opinion or advisory letter from the IRS that could reasonably be expected to adversely affect the qualified status of any such Plan or the exempt status of any such trust. Each trust maintained or contributed to by any Acquired Company or Subsidiary that is intended to be qualified as a voluntary employees’ beneficiary association and that is intended to be exempt from federal income taxation under Section 501(c)(9) of the Code has received a favorable determination letter from the IRS that it is so qualified and so exempt, and no fact or event has occurred since the date of such determination by the IRS to adversely affect such qualified or exempt status.

(e) Absence of Certain Liabilities and Events. There has been no prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code) with respect to any Plan, which is not otherwise exempt under Section 408 of ERISA, and that would reasonably be expected to subject an Acquired Company or Subsidiary to any material liability. No Acquired Company or Subsidiary has incurred any liability for any penalty or tax arising under Section 4971, 4972, 4980, 4980B or 6652 of the Code or any liability under Section 502 of ERISA, and no fact or event exists that could reasonably be expected to give rise to any such liability. No Acquired Company or Subsidiary has incurred any liability under, arising out of or by operation of Title IV of ERISA (other than liability for premiums to the Pension Benefit Guaranty Corporation arising in the ordinary course), including any liability in connection with (i) the termination or reorganization of any employee benefit plan subject to Title IV of ERISA or (ii) the withdrawal from any Multiemployer Plan or Multiple Employer Plan, and no fact or event exists that could give rise to any such liability. No complete or partial termination has occurred within the five years preceding the date hereof with respect to any Plan. No reportable event (within the meaning of Section 4043 of ERISA) has occurred or is expected to occur with respect to any Plan subject to Title IV of ERISA. Except with respect to any Plan that is a Multiemployer Plan, no Plan had an accumulated funding deficiency (within the meaning of Section 302 of ERISA or Section 412 of the Code), whether or not waived, as of the most recently ended plan year of such Plan. None of the assets of any Acquired Company or Subsidiary is the subject of any lien arising under Section 302(f) of ERISA or Section 412(n) of the Code; no Acquired Company or Subsidiary has been required to post any security under Section 307 of ERISA or Section 401(a)(29) of the Code; and no fact or event exists which could reasonably be expected to give rise to any such lien or requirement to post any such security.

(f) Plan Contributions and Funding. All contributions, premiums or payments required to be made with respect to any Plan have been made on or before their due dates. All such contributions have been fully deducted for income tax purposes and no such deduction has been challenged or disallowed by any Governmental Authority, and no fact or event exists that could reasonably be expected to give rise to any such challenge or disallowance.

No such Plan has assets set aside directly or indirectly in the manner described in Section 409A(b)(1) of the Code or contains a provision that would be subject to Section 409A(b)(2) of the Code. Each Section 409A Plan (i) was, for the period beginning on the later of (A) January 1, 2005, and (B) the date of the inception of such Plan, and ending on December 31, 2008, administered in good faith compliance with the requirements of Section 409A of the Code and applicable guidance issued thereunder, (ii) has been, since the later of (A) January 1, 2009, and (B) the date of the inception of such Plan, administered in compliance, in all material respects, with the requirements of Section 409A of the Code and the final regulations issued and outstanding thereunder, and (iii) has been, since the later of (A) January 1, 2009, and (B) the date of the inception of such Plan, in a written form that complies with the requirements of Section 409A of the Code and final regulations issued and outstanding thereunder, such that in the event of an audit by the Internal Revenue Service of either the relevant Acquired Company or Subsidiary or any individual participating in such Plan, no material liability would be incurred by the Acquired Company or Subsidiary with respect to benefits due or accruing under such Plan.

With respect to each Plan that is a Multiemployer Plan, the Sellers have furnished to Purchaser, as applicable (i) the most recently received or obtained estimate of withdrawal liability, (ii) the most recently received or obtained actuarial report, and (iii) any material correspondence relating to its funded status (including any correspondence regarding a funding improvement plan, a rehabilitation plan or a plan reorganization or termination), contribution requirements and legal compliance.

Dycom and the Purchaser have conducted their own independent investigation, review and analysis of the business, results of operations, financial condition and assets of the Acquired Companies and Subsidiaries.

delivered by the Sellers hereunder. Except for such representations and warranties, (a) Dycom and the Purchaser acknowledge and agree that no Seller, Acquired Company, Subsidiary or other Person is making or has made any representation or warranty, expressed or implied, at Law or in equity, in respect of the Business or any Acquired Company or Subsidiary, either Seller or this Agreement, and no officer, agent, representative or employee of any Seller, Acquired Company or Subsidiary has any authority, express or implied, to make any other representations or warranties, or agreements not specifically set forth in this Agreement, any Ancillary Agreement or the License Agreement, and in each case subject to the limited remedies herein provided, (b) each of Dycom and the Purchaser specifically disclaims that it is relying upon or has relied upon any such other representations or warranties that may have been made by any Person, and (c) the Purchaser is acquiring the Acquired Companies based upon the express representations and warranties of the Sellers set forth in this Agreement (including the related portions of the Disclosure Schedule) and any certificate delivered by the Sellers hereunder, and subject to the remedies as set forth in Article IX.

Without limiting the generality of the foregoing, except as described in Section 5.01(a) of the Disclosure Schedule, the Sellers shall cause the Acquired Companies and each Subsidiary to (i) continue their advertising and promotional activities, and pricing and purchasing policies, in accordance with past practice; (ii) not shorten or lengthen the customary payment cycles for any of their payables or receivables; (iii) use their reasonable efforts to (A) preserve intact their business organizations and the business organization of their Business except as contemplated by the Restructuring Transactions, (B) keep available to the Purchaser the services of the employees of each Acquired Company and Subsidiary in the ordinary course and consistent with prior practice (other than any resignation or any termination for cause of any such employee), (C) continue in full force and effect without material modification all existing policies or binders of insurance currently maintained in respect of each Acquired Company and Subsidiary and their Business, and (D) preserve their current relationships with their customers, suppliers and other persons with which they have had significant business relationships; (iv) exercise any rights of renewal pursuant to the terms of any of the leases or subleases set forth in Section 3.18(b) of the Disclosure Schedule which by their terms would otherwise expire; and (v) not engage in any practice, take any action, fail to take any action or enter into any transaction which could cause any representation or warranty of the Sellers to be untrue in any material respect or result in a material breach of any covenant made by the Sellers in this Agreement.

(b) Except as described in Section 5.01(b) of the Disclosure Schedule (those intercompany transactions listed under the heading “Restructuring Transactions” in such Section 5.01(b) of the Disclosure Schedule are referred to herein as the “Restructuring Transactions”), each Seller, jointly and severally, covenants and agrees that, from the date hereof

until the earlier of the time of the Closing and the termination of this Agreement pursuant to Article X, without the prior written consent of the Purchaser (not to be unreasonably withheld, conditioned or delayed), none of the Acquired Companies or Subsidiaries will do any of the things specified in the second sentence of Section 3.12.

(c) At or prior to the Closing, Quanta shall cause Sunesys, LLC (“Sunesys”) to enter into an agreement with Dycom, its Affiliate or an Acquired Company pursuant to which Sunesys, on behalf of itself and its successors and assigns, commits to retain such party to provide, consistent in the amount historically provided, those telecom engineering, construction and maintenance services historically performed by the Acquired Companies prior to the Closing and that are required by Sunesys during the four year period subsequent to the Closing, on terms substantially similar to the terms upon which the Acquired Companies historically performed such services for Sunesys. In addition, at or prior to the Closing, Quanta shall cause Sunesys to transfer to Blair Park Services, LLC the employees named on Section 5.01(c) of the Disclosure Schedule.

SECTION 5.02 Access to Information.

For the avoidance of doubt, to the extent that Sellers determine (after consultation with outside counsel) that disclosure of any such information is not consistent with recommended antitrust practices, Sellers will disclose that information under the terms of the Antitrust Confidentiality Agreement. Notwithstanding anything to the contrary in this Agreement, the Sellers shall not be required to provide any such access or disclose any such information to the Purchaser or Dycom or any such other person if such disclosure would, in the Sellers’ discretion (after consultation with outside counsel), (i) jeopardize any attorney-client or other legal privilege or (ii) contravene any applicable Laws. Nothing contained in this Agreement shall be construed to give to Dycom or the Purchaser, directly or indirectly, any rights to control or direct the operations of any Acquired Company or Subsidiary prior to the Closing Date. Prior to the Closing Date, the Sellers shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision of the operations of the Acquired Companies and the Subsidiaries. Dycom and the Purchaser hereby agree that they are not authorized to and shall not (and shall not permit any of their Affiliates or any of their respective employees, officers, counsel, accountants, consultants, financing sources or other representatives

or agents to) contact any competitor, supplier, distributor, or customer of any Acquired Company or Subsidiary with respect to this Agreement or any of the transactions contemplated hereby prior to the Closing without the prior written consent of Quanta (not to be unreasonably withheld, conditioned or delayed) and, if Quanta so elects, only in the presence of an agent or representative specified by Quanta.

(b) In order to facilitate the resolution of any claims made against or incurred by the Sellers prior to the Closing or for any other reasonable purpose, including Quanta’s SEC reporting obligations, for a period of seven years after the Closing Date, the Purchaser shall (i) retain the books and records relating to the Acquired Companies, the Subsidiaries, their Business and their operations relating to periods prior to the Closing in a manner reasonably consistent with the prior practice of the Acquired Companies and the Subsidiaries and (ii) upon reasonable notice, afford the officers, employees, agents and representatives of the Sellers reasonable access (including the right to make, at the Sellers’ expense, photocopies), during normal business hours, to such books and records.

(c) In order to facilitate the resolution of any claims made against or incurred by the Purchaser or any Acquired Company or Subsidiary after the Closing or for any other reasonable purpose, for a period of seven years following the Closing Date, each Seller shall (i) retain the books and records of such Seller which relate to the Acquired Companies, the Subsidiaries, their Business and their operations for periods prior to the Closing and which shall not otherwise have been delivered to the Purchaser or any Acquired Company or Subsidiary and (ii) upon reasonable notice, afford the officers, employees, agents and representatives of the Purchaser or any Acquired Company or Subsidiary reasonable access (including the right to make photocopies, at the expense of the Purchaser or such Acquired Company or Subsidiary), during normal business hours, to such books and records.

In addition, Dycom and the Purchaser will, and will cause the Acquired Companies and Subsidiaries to, use all reasonable efforts to ensure that the reporting timelines adhered to by the Acquired Companies and Subsidiaries prior to the Closing and as required by Quanta as part of its monthly closing process are complied with for Quanta’s reporting period that includes the Closing Date.

(e) At or promptly following the Closing, Quanta shall provide to the Purchaser all materials that were made available in the physical data room in connection with Dycom’s evaluation of the transactions contemplated hereby, including electronic copies of any lists or summaries prepared with respect to such materials.

SECTION 5.03 Confidentiality. The parties hereto acknowledge and agree that (i) both the Non-Disclosure Agreement and the Antitrust Confidentiality Agreement remain in full force and effect and (ii) both the Non-Disclosure Agreement and the Antitrust Confidentiality Agreement shall terminate and be of no further force and effect from and after

the Closing. From and after the Closing Date until (except with respect to trade secrets) the date that is three years after the Closing Date, each Seller shall, and shall cause its agents, representatives, Affiliates, employees, officers and directors to: (a) except as provided in clause (c) below, treat and hold as confidential (and not disclose or provide access to any Person to) all information relating to trade secrets, processes, patent applications, product development, price, customer and supplier lists, pricing and marketing plans, policies and strategies, details of client and consultant contracts, operations methods, product development techniques, business acquisition plans, new personnel acquisition plans and all other confidential or proprietary information with respect to each Acquired Company and Subsidiary and their Business; provided, however, that notwithstanding the foregoing, the Sellers and their agents, representatives, Affiliates, employees, officers and directors shall be free to use any information retained in their unaided memory (including general ideas, concepts, know-how or techniques contained therein) other than where such use is expressly in violation of another provision of this Agreement, including Sections 5.07 and 5.08 hereof, provided that they shall maintain the confidentiality of the information subject to the foregoing confidentiality restrictions and the foregoing shall not be deemed to grant to the Sellers or any of their agents, representatives, Affiliates, employees, officers or directors a license under the Patent Rights, (b) in the event that such Seller or any such agent, representative, Affiliate, employee, officer or director becomes legally compelled to disclose any such information, provide the Purchaser with prompt written notice of such requirement so that the Purchaser or any Acquired Company or Subsidiary may seek a protective order or other remedy or waive compliance with this Section 5.03, (c) in the event that such protective order or other remedy is not timely obtained, or the Purchaser waives compliance with this Section 5.03, furnish only that portion of such confidential information which is legally required to be provided and exercise its reasonable efforts to obtain assurances that confidential treatment will be accorded such information, and (d) promptly furnish (prior to, at, or as soon as practicable following, the Closing) to the Acquired Companies or the Purchaser any and all copies (in whatever form or medium) of all such confidential information then in the possession of such Seller or any of its agents, representatives, Affiliates, employees, officers or directors or, except as otherwise required or permitted by Section 5.02(c) or to the extent necessary to comply with any applicable Laws, rules or regulations, destroy any and all additional copies then in the possession of such Seller or any of its agents, representatives, Affiliates, employees, officers or directors of such information and of any analyses, compilations, studies or other documents prepared, in whole or in part, on the basis thereof; provided, however, that this sentence shall not apply to any information that (A) at the time of disclosure, is available publicly and was not disclosed in breach of this Agreement by such Seller, its agents, representatives, Affiliates, employees, officers or directors or (B) is lawfully obtained or developed by any Seller, any of its Affiliates or any of their respective agents, representatives, employees, officers or directors from and after the Closing from sources which are not legally prohibited from disclosing such information; and provided further that, with respect to Intellectual Property, specific detailed information shall not be deemed to be within the foregoing exception (A) merely because a principal of operation is embraced in general disclosures in the public domain. In addition, with respect to Intellectual Property, any combination of features shall not be deemed to be within the foregoing exception (A) merely because the individual features are in the public domain unless the combination itself and its principle of operation are in the public domain.

SECTION 5.04 Regulatory and Other Authorizations; Notices and Consents. (a) Each of Dycom, the Purchaser and the Sellers shall use its reasonable best efforts to obtain (or cause the Acquired Companies and the Subsidiaries to obtain) all authorizations, consents, orders and approvals of all Governmental Authorities and officials that may be or become necessary for its execution and delivery of, and the performance of its obligations pursuant to, this Agreement and the Ancillary Agreements and will cooperate fully with the other party in promptly seeking to obtain all such authorizations, consents, orders and approvals. On October 15, 2012, each party hereto filed its Notification and Report Form required under the HSR Act with respect to the transactions contemplated by this Agreement. Each such party shall supply as promptly as reasonably practicable to the appropriate Governmental Authorities any additional information and documentary material that may be requested pursuant to the HSR Act. Notwithstanding the foregoing, (x) this Agreement shall not obligate the Purchaser, Dycom or any of their Affiliates to make any sale, divestiture, license or other disposition of the assets, properties or businesses of the Purchaser, Dycom or any of their Affiliates or of the assets, properties businesses to be acquired pursuant hereto or otherwise take any action that limits the freedom of action with respect to, or its ability to retain, any of the businesses, product lines or assets of the Purchaser, Dycom, and their Affiliates or those that the Purchaser and Dycom are acquiring pursuant to this Agreement, and (y) no party hereto shall be required to pay any fees or other payments to any Governmental Authorities in order to obtain any such authorization, consent, order or approval (other than normal filing fees that are imposed by Law on any of the parties hereto). The Sellers, Dycom, the Purchaser and their respective Affiliates shall not extend any waiting period or comparable period under the HSR Act or enter into any agreement with any Governmental Authority not to consummate the transactions contemplated hereby, except with the prior written consent of the other parties hereto (which consent shall not be unreasonably withheld).

(b) Each party to this Agreement shall promptly notify the other party of any communication it or any of its Affiliates receives from any Governmental Authority relating to the matters that are the subject of this Section 5.04 and permit the other party to review in advance (and to consider any comments made by the other party in relation to) any proposed communication by such party to any Governmental Authority relating to such matters. Neither of the parties to this Agreement shall agree to participate in any substantive meeting, telephone call or discussion with any Governmental Authority in respect of any submissions, filings, investigations, or any other inquiry relating to such matters unless it consults with the other party in advance and, to the extent permitted by such Governmental Authority, gives the other party (or their external legal counsel in order to address any concerns relating to confidential or competitively sensitive information) the opportunity to attend and participate at such meeting, telephone call or discussion. The parties to this Agreement shall, and shall cause their respective Affiliates to, provide each other with copies of all correspondence, filings or communications between them or any of their respective representatives, on the one hand, and any Governmental Authority or members of its staff, on the other hand, with respect to this Agreement and the transactions contemplated by this Agreement; provided, however, that materials may be redacted (i) to remove references concerning the valuation of the Company and its Subsidiaries; (ii) as necessary to comply with contractual arrangements or applicable Laws; and (iii) as necessary to address reasonable attorney-client or other privilege or confidentiality concerns.

(c) The Sellers shall, or shall cause the Acquired Companies and the Subsidiaries to, give promptly such notices to third parties and use its or their reasonable efforts to obtain such third party consents and estoppel certificates necessary or desirable in connection with the transactions contemplated by this Agreement.

(d) The Purchaser shall cooperate and use all reasonable efforts to assist the Sellers in giving such notices and obtaining such consents and estoppel certificates; provided, however, that the Purchaser shall have no obligation to give any guarantee or other consideration of any nature in connection with any such notice, consent or estoppel certificate or to consent to any change in the terms of any agreement or arrangement which the Purchaser in its sole discretion may deem materially adverse to the interests of the Purchaser, any Acquired Company or Subsidiary or their Business.

(e) The Sellers and the Purchaser agree that, in the event that any consent, approval or authorization necessary or desirable to preserve for any Acquired Company or Subsidiary or their Business any right or benefit under any lease, license, contract, commitment or other agreement or arrangement to which any Acquired Company or Subsidiary is a party is not obtained prior to the Closing, the Sellers will, subsequent to the Closing, cooperate with the Purchaser or such Acquired Company or Subsidiary in attempting to obtain such consent, approval or authorization as promptly thereafter as practicable. If such consent, approval or authorization cannot be obtained, the Sellers shall use their reasonable efforts to provide the Purchaser or such Acquired Company or Subsidiary, as the case may be, with the rights and benefits of the affected lease, license, contract, commitment or other agreement or arrangement for the term of such lease, license, contract or other agreement or arrangement, and, if the Seller provides such rights and benefits, such Acquired Company or Subsidiary, as the case may be, shall assume the obligations and burdens thereunder.

SECTION 5.05 Notice of Developments. Prior to the Closing, each party shall promptly notify the other parties in writing of (a) all events, circumstances, facts and occurrences arising subsequent to the date of this Agreement which could result in any material breach of a representation or warranty or covenant of such party in this Agreement or which could have the effect of making any representation or warranty of such party in this Agreement untrue or incorrect in any material respect and (b) all other material developments arising subsequent to the date of this Agreement affecting the assets, Liabilities, business, financial condition, operations, results of operations, customer or supplier relations, employee relations, projections or prospects of such party (or, with respect to the Sellers, the Acquired Companies and Subsidiaries); provided, that the delivery of any notice pursuant to this Section 5.05 shall not limit or otherwise affect the rights or remedies available hereunder to the recipient of such notice.

SECTION 5.06 Intellectual Property. (a) Prior to the Closing, the Sellers shall provide the Purchaser with a schedule that lists all of the applicable filings, recordings and other acts, and all fees, Taxes and other payments, that are required to be made within sixty (60) days after Closing to maintain the validity and enforceability of the Owned Intellectual Property and the Acquired Companies’ and the Subsidiaries’ interest therein.

(b) The Sellers agree that they shall assign or cause to be assigned all right, title and interest in, to and under the Patent Rights from Quanta Associates, L.P. to CertusView Technologies, LLC at the Closing pursuant to a duly executed written assignment agreement substantially in the form attached as Exhibit F hereto (the “Assignment Agreement”).

(d) The Purchaser, the Acquired Companies and the Subsidiaries shall have a limited, non-transferable and non-assignable (except in accordance with Section 11.06), non-sublicenseable, non-exclusive right to use all of the Acquired Companies’ and the Subsidiaries’ existing stocks of (i) signs and vehicles upon which the Retained Names appear as of the Closing Date for a period of two hundred seventy (270) days after the Closing Date and (ii) letterheads, invoice stock, advertisements and promotional materials, inventory and other documents and materials upon which the Retained Names appear as of the Closing Date for a period of ninety (90) days after the Closing Date (the items described in clauses (i) and (ii), the “Existing Stock”), after which dates Dycom and the Purchaser shall cause each Acquired Company and Subsidiary to remove, delete or obliterate all Retained Names from such Existing Stock or cease to use such Existing Stock, respectively; however, for the avoidance of any doubt, Purchaser, Acquired Companies and the Subsidiaries shall not have any right whatsoever to use any of the Retained Names in order to create any new materials. Notwithstanding the foregoing, Dycom and the Purchaser shall cause each Acquired Company and Subsidiary to remove, delete or obliterate all Retained Names from such Existing Stock or cease to use such Existing Stock, in each case, as soon as reasonably practicable after the Closing Date. The Purchaser shall, and shall cause the Acquired Companies and the Subsidiaries to, use the Existing Stock in substantially the same manner as with respect to which the Retained Names were used prior to the Closing and, in any event, agrees that (i) the nature and quality of all goods sold and services rendered by Purchaser and the Acquired Companies and Subsidiaries in connection with the Retained Names and all

Existing Stock shall be consistent in all material respects with the past practice of the Acquired Companies and the Subsidiaries and (ii) the Sellers shall be provided reasonable access, upon reasonable advance written notice, to confirm compliance with clause (i).

(e) Dycom and the Purchaser shall, as soon as reasonably practicable after the Closing Date, but in no event later than sixty (60) days thereafter, cause each Acquired Company and Subsidiary, as applicable, that has a corporate or limited liability company name that contains a Retained Name to file an amended certificate of incorporation or certificate of formation, as applicable, with the appropriate authorities changing its corporate or limited liability company name, respectively, to a corporate or limited liability company name that does not contain any Retained Names, and to supply any additional information and documentary materials that may be requested by the Sellers with respect to such filings.

SECTION 5.07 No Solicitation. (a) From the date of this Agreement until the third anniversary of the Closing Date, except as contemplated in connection with the Restructuring Transactions, each of the Sellers shall not, and shall cause their Affiliates not to, solicit for employment or hire any individuals (i) who are (at any time from the date of this Agreement until the third anniversary of the Closing Date) employees of any of the Acquired Companies or Subsidiaries who are or have been primarily engaged in the provision of telecommunications infrastructure services at the foreman or supervisor level or above or (ii) who are employees of the Purchaser or Dycom with whom the Sellers first came into contact in connection with the negotiation of this Agreement and the consummation of the transactions contemplated hereby.

(b) Notwithstanding the foregoing, (i) the solicitation (as opposed to hire) restrictions in Section 5.07(a) shall not apply to any solicitation by way of general advertising, including general solicitations in any local, regional or national newspapers or other publications or circulars or on internet sites or any search firm engagement which is not directed or focused specifically on employees of the Acquired Companies, the Subsidiaries or their respective Affiliates and (ii) the restrictions in Section 5.07(a) shall not apply to the hiring of a person who has not been so employed for the past six months and who was not solicited by either of the Sellers (or their Affiliates) in violation of this Section 5.07 prior to termination of his or her employment.

(c) From the date of this Agreement until the third anniversary of the Closing Date, each of Dycom and the Purchaser shall not, and shall cause their Affiliates not to, solicit for employment or hire any individuals who are employees of any of the Sellers and their Affiliates (other than the Acquired Companies and the Subsidiaries) with whom Dycom or the Purchaser first came into contact in connection with the negotiation of this Agreement and the consummation of the transactions contemplated hereby; provided, however, that (i) the solicitation (as opposed to hire) restrictions in this Section 5.07(c) shall not apply to any

solicitation by way of general advertising, including general solicitations in any local, regional or national newspapers or other publications or circulars or on internet sites or any search firm engagement which is not directed or focused specifically on employees of any of the Sellers and their Affiliates (other than the Acquired Companies and the Subsidiaries) and (ii) the restrictions in this Section 5.07(c) shall not apply to the hiring of a person who has not been so employed for the past six months and who was not solicited by any of Dycom, the Purchaser and their Affiliates in violation of this Section 5.07(c) prior to termination of his or her employment.

SECTION 5.08 Non Competition. (a) For a period of four years after the Closing, none of the Sellers or their Affiliates shall engage, directly or indirectly, in the Business or the Restricted Services or, without the prior written consent of the Purchaser, directly or indirectly, own an interest in, manage, operate, join, control, lend money or render financial or other material assistance to or participate in any Person that engages in the Business or the Restricted Services; provided, however, that, for the purposes of this Section 5.08, ownership of securities having no more than five percent of the outstanding voting power of any such Person that is listed on any national securities exchange shall not be deemed to be in violation of this Section 5.08 as long as the Person owning such securities has no other material connection or relationship with such competitor; provided, further, that the Sellers and their Affiliates shall not be deemed to be in violation of this Section 5.08 as a result of (i) performing their obligations under this Agreement or the Ancillary Agreements, (ii) acquiring any Person or business that engages in the Business so long as (1) the Business contributed less than 25% or more of the average total annual revenue of such Person or business for the two fiscal years prior to the time of the acquisition and (2) the total annual revenue derived from the Business of all Persons or businesses acquired pursuant to the exception in this clause (ii) since the Closing Date remains less than $75 million, (iii) providing telecommunication infrastructure services pursuant to the contracts or agreements, in each case identified in Section 5.08(a) of the Disclosure Schedule until the expiration or termination of such contracts or agreement in accordance with its existing terms with respect to scope and territory (iv) any other services performed for any telecommunications customer(s) contributing revenues not in excess of $10 million in any fiscal year of Quanta, and (v) as contemplated by the Restructuring Transactions.

(b) The Sellers acknowledge that the covenants of the Sellers set forth in this Section 5.08 are an essential element of this Agreement and that, but for the agreement of the Sellers to comply with these covenants, the Purchaser would not have entered into this Agreement. The Sellers agree that the duration and scope of the non-competition provision set forth in this Section 5.08 are reasonable. In the event that any court determines that the duration or scope of the restrictions set forth in this Section 5.08, or both, is unreasonable and that such provision is to that extent unenforceable, the parties hereto agree that the provision shall remain in full force and effect for the greatest time period and in the greatest scope that would not render it unenforceable. The parties acknowledge and agree that because it would be impossible to measure the Purchaser’s economic losses resulting from a breach of this Section 5.08 and because such a breach would result in immediate and irreparable damage to the Purchaser, the Purchaser shall be entitled to enforce the provisions of this Section 5.08 by means of injunctions, restraining orders and other equitable Actions.

SECTION 5.09 Release of Indemnity Obligations. (a) From and after the Closing, each Seller, on behalf of itself and each of its Affiliates (excluding the Acquired

Companies and the Subsidiaries), hereby releases and forever discharges the Acquired Companies and the Subsidiaries, and each of their respective individual, joint or mutual, past and present officers, directors, employees, representatives and agents, successors and assigns, in their respective capacities as such (collectively, the “Acquired Company Releasees”), from any and all claims, demands, actions, obligations, contracts, agreements, debts and Liabilities whatsoever, whether known or unknown, suspected or unsuspected, both at Law and in equity, which any of the Sellers or any of their respective Affiliates (other than the Acquired Companies and the Subsidiaries) now has, have ever had or may hereafter have against the respective Acquired Company Releasees arising prior to or contemporaneously with the Closing or on account of or arising out of any matter, cause or event occurring contemporaneously with or prior to the Closing, whether or not relating to claims pending on, or asserted after, the Closing. Notwithstanding the foregoing, nothing in this Section 5.09(a) shall in any way limit or otherwise restrict any rights the Sellers or any of their respective Affiliates may have against the Purchaser or Dycom or any of their respective Affiliates arising out of, relating to or in connection with this Agreement, the License Agreement or the Ancillary Agreements and the transactions contemplated hereby or thereby or those contracts or arrangements set forth in Section 5.10 of the Disclosure Schedule.

(b) From and after the Closing, each of the Acquired Companies and the Subsidiaries hereby releases and forever discharges the Sellers and their respective Affiliates, and each of their respective individual, joint or mutual, past and present officers, directors, employees, representatives and agents, successors and assigns in their respective capacities as such (collectively, the “Seller Releasees”) from any and all claims, demands, actions, obligations, contracts, agreements, debts and Liabilities whatsoever, whether known or unknown, suspected or unsuspected, both at Law and in equity, which any such Acquired Companies or Subsidiaries now has, have ever had or may hereafter have against the respective Seller Releasees arising prior to or contemporaneously with the Closing or on account of or arising out of any matter, cause or event occurring contemporaneously with or prior to the Closing, whether or not relating to claims pending on, or asserted after, the Closing. Notwithstanding the foregoing, nothing in this Section 5.09(b) shall in any way limit or otherwise restrict any rights the Purchaser or any of its Affiliates may have against the Sellers or their Affiliates arising out of, relating to or in connection with this Agreement, the License Agreement or the Ancillary Agreements and the transactions contemplated hereby or thereby or those contracts or arrangements set forth in Section 5.10 of the Disclosure Schedule.

SECTION 5.10 Intercompany Arrangements. At or prior to the Closing, the Sellers shall cause any contract or arrangement that is disclosed (or should have been disclosed) in Section 3.16(a)(viii) of the Disclosure Schedule, other than those contracts or arrangements set forth in Section 5.10 of the Disclosure Schedule, to be terminated or otherwise amended or modified to exclude any Acquired Companies and Subsidiaries as a party thereto, in each case to the extent that Dycom and the Purchaser have satisfied their obligations pursuant to Section 5.15 with respect to any such contracts, agreements or arrangements that constitute Credit Support Instruments.

SECTION 5.11 Transition Services. Following the Closing, the Sellers shall provide, or cause to be provided, to the Acquired Companies and Subsidiaries certain services that are currently provided by the Sellers and its Affiliates to their Business, all as more fully set

forth in a transition services agreement substantially in the form attached hereto as Exhibit H (the “Transition Services Agreement”) to be entered into by the Sellers, Dycom and the Purchaser as of the Closing.

SECTION 5.12 Financial Statements. (a) The Sellers hereby consent to the inclusion or incorporation by reference of the Audited Financial Statements and Unaudited Financial Statements in any registration statement, offering memorandum, report or other filing of the Purchaser or any of its Affiliates as to which the Purchaser or any of its Affiliates reasonably determines that such financial statements are required to be included or incorporated by reference to satisfy any rule or regulation of the SEC or to satisfy relevant disclosure obligations under the Securities Act or the Exchange Act or as otherwise necessary in connection with the Financing. The Sellers shall use reasonable efforts to cause their independent accountant to consent to the inclusion or incorporation by reference of its audit opinion with respect to any of the financial statements of the Acquired Companies in any such registration statement, offering memorandum, report or other filing of the Purchaser or its Affiliates, and the Sellers shall use their reasonable efforts to cause representation letters, in form and substance reasonably satisfactory to the Purchaser, to be executed and delivered by its independent accountants in connection with obtaining any such consent.

(b) The Sellers shall use reasonable efforts to cooperate with the Purchaser in connection with the preparation by the Purchaser of any pro forma financial statements of the Purchaser or any of its Affiliates that are derived in part from the financial statements of the Acquired Companies that the Purchaser or its Affiliates reasonably determines are required to be included or incorporated by reference in any registration statement, report or other filing of the Purchaser or its Affiliates to satisfy any rule or regulation of the SEC or to satisfy relevant disclosure obligations under the Securities Act or the Exchange Act or as otherwise reasonably necessary in connection with the Financing.

(c) To the extent not previously paid or reimbursed pursuant to the terms of the Letter of Intent, Dycom shall promptly pay or reimburse the Sellers, as Quanta may direct, for (i) all fees, disbursements, costs and expenses incurred by the Sellers’ third party accountants in connection with the Unaudited Financial Statements and Audited Financial Statements (including, without limitation, auditor comfort letters and consents) in an amount not to exceed $1,000,000 and (ii) specific incentive compensation amounts set forth on Section 5.12(c) of the Disclosure Schedule paid to certain personnel of the Acquired Companies for the purpose of completing the Unaudited Financial Statements and Audited Financial Statements and other matters related to the transactions contemplated hereby in an amount not to exceed $200,000.

SECTION 5.13 Financing. Prior to the Closing, the Sellers shall provide, and shall use reasonable efforts to cause their respective representatives and advisors, including legal, tax, regulatory and accounting advisors, to provide, customary cooperation in connection with the arrangement of the Financing (provided that, for purposes of this Section 5.13, the Financing shall include, and the obligations under this Section 5.13 shall also be applicable with respect to, required SEC reporting obligations of Purchaser subsequent to the Closing, and any offering of “high yield” debt financing consummated, in each case within six months of the Closing Date), as may be reasonably requested by the Purchaser, including: (i) causing the Acquired Companies and Subsidiaries to execute and deliver customary guarantee, pledge and security documents or

other definitive financing documents or other certificates, legal opinions and documents as may be reasonably requested by the Purchaser, provided, however, that no obligation of any of the Acquired Companies or Subsidiaries, under any such document or agreement, as applicable, is effective until the Closing; (ii) furnishing the Purchaser and its financing sources with the most recent combined financial statements, financial data and other information of the Acquired Companies reasonably requested by the Purchaser or its financing sources in connection with the Financing; (iii) assisting any financing sources in the preparation of (A) one or more customary offering documents in connection with the Financing in form and substance that is customary for registration statements filed with the SEC and (B) customary materials with respect to the Acquired Companies for inclusion in rating agency presentations; (iv) using reasonable efforts to obtain accountants’ comfort letters as reasonably requested by the Purchaser; (v) taking such corporate actions (subject to the occurrence of Closing) reasonably required to permit the consummation of the Financing; (vi) cooperating reasonably with the financing sources’ due diligence of the Acquired Companies and their Business and (vii) taking other actions reasonably requested by the Purchaser and/or its financing sources in connection with the Financing; provided, however, that, notwithstanding anything in this Agreement to the contrary, (x) such requested cooperation shall not unreasonably interfere with the ongoing operations of the Sellers, the Acquired Companies or the Subsidiaries and (y) none of the Sellers at any time or the Acquired Companies or the Subsidiaries prior to the Closing shall be required to (1) pay any commitment or other fee, (2) incur any liability or obligation under any indenture, loan agreement or any related document or any other agreement or document related to the Financing or (3) incur any other liability or obligation in connection with the Financing. Any information provided by the parties hereto in connection with the Financing shall be prepared in good faith and shall be free of any material misstatements or omissions. The Purchaser and Dycom shall promptly upon request by the Sellers, reimburse the Sellers for all reasonable and documented out-of-pocket costs incurred by the Sellers in connection with cooperation provided for in this Section 5.13 and execute, deliver and provide such documentation as the Sellers may reasonably request in connection with therewith.

SECTION 5.14 Vehicle Leases. Each of the Sellers, on the one hand, and Dycom and the Purchaser, on the other hand, shall cause, at the Closing, (a) each Leased Vehicle to be sold by the respective lessor of such Leased Vehicle to the Purchaser or one of the Acquired Companies or Subsidiaries for the applicable Buy-Out Amount and (b) upon such sale, such lessor to release the Sellers and their Affiliates, in form and substance reasonably satisfactory to the Sellers, from all obligations with respect to the Leased Vehicles. Section 5.14 of the Disclosure Schedule sets forth, to the Sellers’ Knowledge, the respective lessor’s estimated Buy-Out Amount for each Leased Vehicle as of a date on or about the applicable dates set forth in Section 5.14 of the Disclosure Schedule, subject to adjustments in connection with, among other things, final vehicle mileage determinations, applicable taxes and additional lease payments. All costs and expenses incurred in connection with the actions described in this Section 5.14 (including payment of the Buy-Out Amount) shall be borne by Dycom and the Purchaser.

SECTION 5.15 Release from Credit Support Instruments. (a) At or prior to the Closing, the Purchaser and Dycom shall use reasonable efforts to secure the unconditional release, as of the Closing Date, of the Sellers and their respective Affiliates from the credit support instruments set forth in Section 5.15(a) of the Disclosure Schedule (the “Credit Support

Instruments”), including effecting such release by providing guarantees or other credit support, and the Purchaser and Dycom shall use reasonable efforts to be substituted in all respects for each Seller and each Affiliate of any Seller that is party to the Credit Support Instrument, so that Dycom and the Purchaser (or an Affiliate of the Purchaser) or a surety for the benefit of Dycom and the Purchaser shall be solely responsible for the obligations of such Credit Support Instrument; provided, however, that in no event shall reasonable efforts require the Purchaser or its Affiliates to agree (a) to make any payment (other than in respect of replacement surety bonds obtained on behalf of Dycom and its Affiliates or other credit support required in connection with surety bonds of Dycom and its Affiliates, including the Acquired Companies and Subsidiaries at and after the Closing) to obtain such release (other than ordinary processing or administrative fees), (b) to change the terms of any Material Contract to which such credit support applies in any manner that is materially adverse to the Purchaser or any of its Affiliates (including the Acquired Companies) or (c) to any material restriction in the operations of their respective businesses (including the Business) except for covenants and restrictions that are customary in connection with such Credit Support Instruments or such other credit support documentation contemplated by this Section 5.15. To the extent the Purchaser is unable to obtain such release for any Credit Support Instrument prior to the Closing, (i) Dycom and the Purchaser shall jointly and severally indemnify and hold harmless the Sellers and their respective Affiliates for any and all Losses arising from or relating to the Credit Support Instruments (it being understood that such obligation shall not impair any rights of the Purchaser Indemnified Parties to indemnification under Article IX in respect of any such Losses) and (ii) the Purchaser and Dycom shall continue to use reasonable efforts to secure the unconditional release of the Sellers and their respective Affiliates from the Credit Support Instruments as promptly as reasonably practicable. To the Sellers’ Knowledge, there is no fact or circumstance that would reasonably be expected to give rise to an obligation by any Person who will provide a Credit Support Instrument to perform with respect to such Credit Support Instrument or that would require Quanta or an Affiliate to indemnify such person with respect to any such Credit Support Instrument, other than joint and several obligations for expenses and obligations in the ordinary course of business pursuant to such Credit Support Instruments. Following the Closing, Quanta shall pay to Dycom any premium refund, rebate, credit or similar payment received by Quanta or its Affiliates as a direct result of obtaining the releases of the surety bonds included in the Credit Support Instruments contemplated by this Section 5.15(a).

(b) At or prior to the Closing, the Sellers shall use reasonable efforts to secure the unconditional release, as of the Closing Date, of the Acquired Companies and Subsidiaries from the credit support instruments set forth in Section 5.15(b) of the Disclosure Schedule (the “Other Credit Support Instruments”), so that the Sellers (or one or more Affiliates of the Sellers other than the Acquired Companies and Subsidiaries) shall be solely responsible for the obligations of such Other Credit Support Instrument. To the extent the Sellers are unable to obtain such release for any such Other Credit Support Instrument prior to the Closing, (i) the Sellers shall jointly and severally indemnify and hold harmless Dycom, the Purchaser, the Acquired Companies and their Affiliates for any and all Losses arising from or relating to such Other Credit Support Instrument (it being understood that such obligation shall not impair any rights of the Seller Indemnified Parties to indemnification under Article IX in respect of any such Losses) and (ii) the Sellers shall continue to use reasonable efforts to secure the unconditional release of the Acquired Companies and Subsidiaries from such Other Credit Support Instrument as promptly as reasonably practicable.

SECTION 5.16 Retained Insurance Claims. Quanta shall remain liable for, and continue to manage and pay out in the ordinary course of business consistent with past practice, the Retained Insurance Claims.

SECTION 5.17 Disclosure Schedule. Inclusion of any item in the Disclosure Schedule: (i) does not represent a determination by the Sellers that such item is material, nor shall it be deemed to establish a standard of materiality now or in the future (it being the intent that the Sellers shall not be penalized for having disclosed more than may be required by the applicable provision of this Agreement), (ii) does not represent a determination by the Sellers that such item did not arise in the ordinary course of business and (iii) shall not constitute, or be deemed to be, an admission of liability concerning such item by the Sellers. In addition to their obligations under Section 5.05, from time to time prior to the Closing, the Sellers shall have the right (but not the obligation) to supplement or amend those portions of the Disclosure Schedule that modify the representations and warranties contained in Article III other than the Seller Fundamental Representations with respect to any matter hereafter arising or of which it becomes aware after the date hereof (each a “Schedule Supplement”), and each such Schedule Supplement shall be deemed to be incorporated into and to supplement and amend the Disclosure Schedule as of the Closing Date; provided, however, that in the event that such event, development or occurrence which is the subject of the Schedule Supplement constitutes or relates to something that would give rise to a right by the Purchaser to terminate this Agreement under Section 10.01(a) and the Purchaser has the right to, but does not elect to terminate this Agreement within five Business Days of its receipt of such Schedule Supplement, then the Purchaser shall be deemed to have irrevocably waived such right to terminate this Agreement and any condition to Closing set forth in Section 8.02 with respect to the specific matters set forth in such Schedule Supplement; provided, further, that any Schedule Supplement provided pursuant to this Section 5.17 shall be disregarded for purposes of determining whether there has been a breach of any representation or warranty and any indemnification obligations based on such breach of the Sellers pursuant to Article IX.

SECTION 5.18 Further Action. (a) Each of the parties hereto shall use all reasonable efforts to take, or cause to be taken, all appropriate action, do or cause to be done all things necessary, proper or advisable under applicable Law, and to execute and deliver such documents and other papers, as may be required to carry out the provisions of this Agreement and the Ancillary Agreements to which it is a party and consummate and make effective the transactions contemplated hereby and thereby, including taking such actions as are necessary to expeditiously satisfy the closing conditions set forth in Article VIII.

(b) Notwithstanding the provisions of Section 2.01, the Sellers acknowledge and agree that certain assets that constitute Purchased Assets may not have been transferred to the Purchaser pursuant to this Agreement. If, following the Closing, the Sellers, Dycom or the Purchaser determines, acting reasonably and in good faith, that any Purchased Assets were not so transferred, the parties agree to cooperate to transfer such Purchased Assets to the Purchaser without the payment of any further consideration.

(c) Dycom and the Purchaser acknowledge and agree that certain amounts may be received by the Acquired Companies or Subsidiaries following the Closing in respect of the CVIN Claim. From and after the Closing, if the Acquired Companies or Subsidiaries

receives or collects any funds relating to the CVIN Claim, Dycom shall cause such Acquired Company or Subsidiary to remit such funds to Quanta within five Business Days after the receipt thereof; provided that the foregoing shall not apply to any funds relating to Receivables reflected in Net Working Capital on the Closing Statement.

(d) Quanta will use reasonable efforts to cooperate with Dycom and the Purchaser in obtaining executed Employment Documents prior to the Closing from those individuals listed in Section 5.18(d) of the Disclosure Schedule.

ARTICLE VI

EMPLOYEE MATTERS

SECTION 6.01 Benefits. (a) Except as provided below, as of the Closing Date, each then-current employee of the Acquired Companies and the Subsidiaries (a “Transferred Employee”) shall cease to be covered by the Plans and shall be covered by the employee benefit plans of Purchaser. The Transferred Employees shall remain covered under the Plans listed in Section 6.01(a) of the Disclosure Schedule in effect prior to the Closing (the “Specified Welfare Plans”) until the last day of the month in which the Closing occurs, after which the Transferred Employees shall be covered by the corresponding plans of Purchaser (if Purchaser has corresponding plans). Within 20 days following the last day of the month in which Closing occurs, Purchaser shall make a cash payment to the Sellers equal to the employee-paid portion of premiums or contributions for the Specified Welfare Plans collected by Purchaser. The medical, dental and health plans of the Purchaser applicable to each Transferred Employee (i) shall not contain any exclusions for pre-existing conditions (other than conditions which barred coverage under the corresponding Plans), (ii) shall cover as of the first day of the month following the month in which Closing occurs each Transferred Employee who was covered by a comparable Plan immediately prior to the date of the Closing and (iii) shall credit each Transferred Employee for the plan year of the Sellers in which the date of the Closing occurs with all deductibles and co-payments applicable to the portion of such plan year occurring prior to the date of the Closing. In addition, the Purchaser shall grant each Transferred Employee full credit for all periods of employment with the Sellers, the Acquired Companies and the Subsidiaries for eligibility, vesting and accrual purposes under the employee benefit plans of the Purchaser applicable to such Transferred Employee (except that this sentence shall not obligate the Purchaser to grant benefit accrual service under any defined benefit pension plan for any period of employment occurring prior to the date of the Closing); provided, however, that such crediting of service shall not operate to duplicate any benefit to any such employee or the funding for any such benefit.

(b) Dycom will accept, maintain and pay out in cash, in the ordinary course consistent with past practice and in accordance with the terms of the relevant Plan, the 2012 incentive bonus plans that Quanta and the Acquired Companies and Subsidiaries have in place with respect to the applicable participants at the Acquired Companies and Subsidiaries for the year ending December 31, 2012. The estimated amounts payable in respect of such Plans have been reflected in the Unaudited Financial Statements and approximately 11/12ths of the aggregate amount estimated to be paid for the year ended December 31, 2012 has been accrued as a Current Liability of the Acquired Companies and the Subsidiaries.

ARTICLE VII

TAX MATTERS

SECTION 7.01 Indemnity. (a) The Sellers agree to indemnify and hold harmless the Purchaser, and each Acquired Company and Subsidiary against Excluded Taxes, except to the extent that such Excluded Taxes were included in the determination of Net Working Capital and, except as otherwise provided in this Article VII, against any loss, damage, liability or expense, including reasonable fees for attorneys and other outside consultants incurred in contesting or otherwise in connection with any such Taxes.

(b) Sellers and Purchaser agree to cause each Acquired Company and Subsidiary to close its books or terminate its taxable period as of the end of the Closing Date where such action is permitted under applicable Law solely as a result of the sale of the Shares and Purchased Assets under this Agreement. In the case of Taxes that are payable with respect to a Straddle Period, the portion of any such Tax that is allocable to the portion of the Straddle Period ending on the date of the Closing shall be:

(i) in the case of Taxes that are either (x) based upon or related to income or receipts, or (y) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible) (other than conveyances pursuant to this Agreement, as provided under Section 7.07), deemed equal to the amount which would be payable if the taxable year ended on the date of the Closing; and

(ii) in the case of Taxes imposed on a periodic basis with respect to the assets of any Acquired Company or Subsidiary or otherwise measured by the level of any item, deemed to be the amount of such Taxes for the entire 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 period ending on the date of the Closing and the denominator of which is the number of calendar days in the entire Straddle Period. Any credit or refund resulting from an overpayment of Taxes for a Straddle Period shall be prorated based upon the method employed in this paragraph (b) taking into account the type of the Tax to which the refund relates. In the case of any Tax based upon or measured by capital (including net worth or long term debt) or intangibles, any amount thereof required to be allocated under this Section 7.01(b) shall be computed by reference to the level of such items on the date of the Closing. All determinations necessary to effect the foregoing allocations shall be made in a manner consistent with prior practice of the Acquired Companies and the Subsidiaries.

(iii) Notwithstanding anything to the contrary herein, the amount of any expenses or costs (including any compensation or bonuses) incurred by the Acquired Companies and the Subsidiaries in connection with the consummation of the transactions contemplated under this Agreement, in each case to the extent deductible by the Acquired Companies or the Subsidiaries in a taxable period ending on the Closing Date under applicable Law, that are (i) paid by the Acquired Companies or Subsidiaries on or prior to the Closing Date, (ii) paid by Sellers (whether before or after the Closing) or (iii) taken

into account in determination of the amount of the Purchase Price (which Purchase Price would have been higher if it were not taken into account) shall be taken as a deduction on the Tax Returns of the Acquired Companies and Subsidiaries that are filed for the taxable period ending on the Closing Date and, in the case of any Tax Returns filed for a Straddle Period, such deductions shall be allocated to the pre-Closing portion of the Straddle Period to the extent not prohibited by Law. For this purpose, the safe harbor of Revenue Procedure 2011-29, 2011-18 IRB 746 shall be applied in determining the deductible amount of “success-based fees.”

(c) Notwithstanding anything to the contrary contained in this Agreement, (i) Sellers shall not be liable for any claim for indemnification for Non-Income Taxes pursuant to Section 7.01(a), unless and until the aggregate amount of Non-Income Taxes which may be recovered from the Sellers equals or exceeds $100,000 whereupon Purchaser, the Acquired Companies and Subsidiaries shall be entitled to indemnification only to the extent of the amount, if any, that exceeds $100,000, (ii) Sellers shall not be liable for any claim for indemnification for Taxes attributable to actions taken by, or at the direction of, Dycom, the Purchaser or any of their Affiliates that are effective on the Closing Date and not contemplated by this Agreement and (iii) the maximum amount of Non-Income Taxes which may be recovered from Sellers under this Section 7.01 shall be an amount equal to the Purchase Price.

SECTION 7.02 Returns and Payments. (a) After the Closing, the Sellers, at their sole expense, shall prepare and file or otherwise furnish in proper form to the appropriate Governmental Authority (or cause to be prepared and filed or so furnished) in a timely manner all Income Tax Returns relating to the Acquired Companies and the Subsidiaries for any taxable period ending on the Closing Date. Except as otherwise required by applicable Law, or to the extent the Acquired Companies determine that a Tax Return cannot be so prepared and filed without being subject to penalties, such Income Tax Returns of the Acquired Companies and the Subsidiaries shall be prepared in a manner consistent with past practices employed with respect to the Sellers, the Acquired Companies and the Subsidiaries. With respect to such Income Tax Return that is a Stand-Alone Return and the portion of any such Income Tax Return that is not a Stand-Alone Return that pertains to the Acquired Companies and the Subsidiaries, Sellers shall provide Purchaser and its authorized representatives with a copy of such completed Tax Return (or portion thereof, in the case of a Tax Return that is not a Stand-Alone Return), together with appropriate supporting information and schedules at least 20 Business Days prior to the due date (including any extension thereof) for the filing of such Tax Return, and Purchaser and its authorized representatives shall have the right to review and comment on such Tax Return prior to the filing of such Tax Return. The Sellers shall take into account the comments of the Purchaser in good faith.

(b) Except as otherwise provided in Section 7.02(a), Purchaser, at its sole expense, shall prepare and file or otherwise furnish in proper form to the appropriate Governmental Authority (or cause to be prepared and filed or so furnished) in a timely manner all other Tax Returns relating to the Acquired Companies and the Subsidiaries for any Pre-Closing Period or any Straddle Period that are required to be filed after the Closing Date. Except as otherwise required by applicable Law or to the extent the Acquired Companies determine that a Tax Return cannot be so prepared and filed without being subject to penalties, such Tax Returns of the Acquired Companies and the Subsidiaries shall be prepared in a manner consistent

with past practices employed with respect to the Acquired Companies and the Subsidiaries. Purchaser shall provide Sellers and their authorized representatives with a copy of such completed Tax Returns that are Income Tax Returns and, if applicable, a statement certifying the amount of Tax shown on such Income Tax Return that is allocable to Sellers pursuant to Section 7.01, together with appropriate supporting information and schedules at least 20 Business Days prior to the due date (including any extension thereof) for the filing of such Income Tax Return, and Sellers and their authorized representatives shall have the right to review and comment on such Income Tax Return and statement prior to the filing of such Income Tax Return. The Purchaser shall take into account the comments of the Sellers in good faith. With respect to any Non-Income Tax Returns prepared by Purchaser, Purchaser shall provide Sellers and their authorized representatives with a copy of such Non-Income Tax Returns if such Non-Income Tax Returns show a Tax due and owing allocable to Seller under Section 7.01 (along with a statement certifying the amount of Tax shown on such Non-Income Tax Return that is allocable to Sellers pursuant to Section 7.01), together with appropriate supporting information and schedules at least 20 Business Days, if practical, prior to the due date (including any extension thereof) for the filing of such Tax Return, and, in no event, later than 10 days after such Tax Return has been filed.

(c) The Sellers shall pay, or cause to be paid, all unpaid Taxes shown due and payable on any Tax Returns prepared and filed by Sellers pursuant to Section 7.02(a) with respect to the Acquired Companies and the Subsidiaries, except to the extent that such unpaid Taxes were included in the determination of Net Working Capital. Purchaser shall pay, or cause to be paid, all unpaid Taxes shown due and payable on Tax Returns prepared and filed by Purchaser pursuant to Section 7.02(b) with respect to the Acquired Companies and the Subsidiaries (subject to its right of indemnification from the Sellers under Section 7.01 by the date set forth in Section 7.05 for Taxes for a Pre-Closing Period or attributable to the pre-Closing portion of any Straddle Period pursuant to Sections 7.01(a) and 7.01(b), provided that the limitations of Section 7.01(c) shall not apply).

SECTION 7.03 Refunds. Any Tax refund or overpayment that is applied as a credit (including any interest with respect thereto) relating to any Acquired Company or Subsidiary for any Pre-Closing Period or the pre-Closing portion of a Straddle Period shall be the property of the Sellers, and if received by, or credited to, the Purchaser, an Affiliate of the Purchaser, any Acquired Company or Subsidiary shall be paid over promptly to the Sellers. Notwithstanding the foregoing, (a) any Tax refund (or equivalent benefit to the Sellers through a reduction in Tax liability) for any Pre-Closing Period arising out of the carryback of a loss or credit incurred by any Acquired Company or Subsidiary in any Post-Closing Period, which under applicable Law is required to be carried back to a Pre-Closing Period, shall be the property of the Purchaser and, if received by the Sellers or an Affiliate of the Sellers, shall be paid over promptly to the Purchaser; (b) if a Governmental Authority subsequently disallows any refund with respect to which the Sellers has received a payment pursuant to this Section 7.03, the Sellers shall promptly pay (or cause to be paid) to the Purchaser the amount of such refund to the extent disallowed (including any interest with respect thereto) and (c) if a Governmental Authority subsequently disallows any refund with respect to which the Purchaser has received a payment pursuant to this Section 7.03(a) by reason of an adjustment to the carryback loss or credit, then Purchaser shall promptly pay (or cause to be paid) to the Sellers the amount of such refund to the extent such Governmental Authority requires the Sellers to pay the amount disallowed (including

any interest with respect thereto). Unless otherwise required under applicable Law, Purchaser shall, and shall cause the Acquired Companies and Subsidiaries, not to carry back any loss or credit incurred by any Acquired Company or Subsidiary in any Post-Closing Period to a Pre-Closing Period.

SECTION 7.04 Contests. (a) After the Closing, the Purchaser shall promptly notify the Sellers in writing of any written notice of the commencement of any Action or proposed assessment or Claim made against, or with respect to, the Purchaser or any of the Acquired Companies or Subsidiaries which (i) relates to a Pre-Closing Period or a Straddle Period of any Acquired Company or Subsidiary or (ii) if determined adversely to the taxpayer, could be grounds for indemnification under this Article VII (a “Tax Action”); provided, however, that the failure to give such notice will not affect the Purchaser’s right to indemnification under this Article VII except to the extent, if any, that, but for such failure, the Sellers could have avoided all or a portion of the Tax liability in question.

(b) In the case of a Tax Action (other than a Tax Action that relates to a Straddle Period), provided that, and only to the extent that, the Sellers acknowledge in writing their liability under this Agreement to hold the Purchaser, the Acquired Companies and the Subsidiaries harmless against the amount of any adjustment which may be made as a result of such audit or proceeding that relates to Pre-Closing Periods to the extent so provided under Section 7.01, the Sellers shall have the right, at their expense, to control the conduct of the Tax Action, provided that the Sellers shall keep the Purchaser informed as to the progress of the Tax Action in a timely manner. The Purchaser may also, at its expense, participate in, but not control, any such Tax Action to the extent that it is related to a Stand-Alone Return or a Non-Income Tax Return and, if the Sellers do not assume the defense of a Tax Action, the Purchaser may defend the same in such manner as it may deem appropriate. In the case of a Tax Action that relates to a Straddle Period, the Purchaser shall have the right, at its expense, to control the Tax Action; the Sellers may also, at their expense, participate in, but not control, any such Tax Action and, if the Purchaser does not assume the defense of any such Tax Action, the Sellers may defend the same in such manner as they may deem appropriate.

(c) In the event that there is a Tax Action that involves (i) the commencement of a tax examination or audit of one or more Pre-Closing Periods and either a Straddle Period and/or one or more Post-Closing Periods and (ii) the same type of Non-Income Tax (or Income Tax, if no Section 338(h)(10) Election was allowed by the relevant Governmental Authority or a Governmental Authority is challenging a Section 338(h)(10) Election) is at issue with respect to all such periods, then, the Sellers and the Purchaser may participate in the audit or examination and the audit or examination shall be jointly controlled by Sellers and Purchaser with respect to the Non-Income Tax (or Income Tax) at issue, provided, however, that at the point that it can be reasonably determined which party would have the burden of the greater portion of the sum of any proposed adjustments and any corresponding adjustments for such periods, then that party shall control the audit and examination

(d) Notwithstanding anything to the contrary in this Section 7.04, with respect to any taxable period that begins before the Closing Date, neither the Purchaser nor the Sellers shall enter into any compromise or agree to settle any Tax Action which would adversely affect the other party for such taxable period or a subsequent taxable period without the written consent

of the other party, which consent may not be unreasonably withheld, conditioned or delayed. The Purchaser and the Sellers agree to cooperate, and the Purchaser agrees to cause the Acquired Companies and the Subsidiaries to cooperate, in the defense against or compromise of any Tax Action.

SECTION 7.05 Time of Payment. Payment by the Sellers of any amounts due under this Article VII in respect of Taxes shall be made (a) at least three Business Days before the due date of the applicable estimated or final Tax Return required to be filed by the Purchaser for which the Sellers are responsible under Sections 7.01(a) and 7.01(b) without regard to whether the Tax Return shows overall net income or loss for such period or (b) within ten Business Days following an agreement between the Sellers and the Purchaser that an indemnity amount is payable, a non-appealable final assessment of a Tax by a Governmental Authority, or a “determination” as defined in Section 1313(a) of the Code. If liability under this Article VII is in respect of costs or expenses other than Taxes, payment by the Sellers of any amounts due under this Article VII shall be made within ten Business Days after the date when the Sellers have been notified by the Purchaser that the Sellers have a liability for a determinable amount under this Article VII and are provided with calculations or other materials supporting such liability.

SECTION 7.06 Tax Cooperation and Exchange of Information. The Sellers and the Purchaser shall provide each other with such cooperation and information as either of them reasonably may request of the other (and the Purchaser shall cause the Acquired Companies and the Subsidiaries to provide such cooperation and information) in (a) filing any Tax Return, amended Tax Return or claim for refund, (b) determining a liability for Taxes or a right to a refund of Taxes, or (c) participating in or conducting any audit or other proceeding in respect of Taxes. Such cooperation and information shall include providing copies of relevant Tax Returns or portions thereof to the extent related to the Acquired Companies and the Subsidiaries, together with related work papers and documents relating to rulings or other determinations by Governmental Authorities. The Sellers and the Purchaser shall make themselves (and their respective employees) reasonably available on a mutually convenient basis to provide explanations of any documents or information provided under this Section 7.06. Notwithstanding anything to the contrary in Section 5.02, each of the Sellers and the Purchaser shall retain all Tax Returns, work papers and all material records or other documents in its possession (or in the possession of its Affiliates) relating to Tax matters of the Acquired Companies or any Subsidiary for any taxable period that includes the Closing Date and for all prior taxable periods until the later of (i) the expiration of the statute of limitations of the taxable periods to which such Tax Returns and other documents relate, without regard to extensions and (ii) six years following the due date (without extension) for such Tax Returns. After such time, before the Sellers or the Purchaser shall dispose of any such documents in its possession (or in the possession of its Affiliates), the other party shall be given an opportunity, after 90 days prior written notice, to remove and retain all or any part of such documents that relate solely to the Acquired Companies and the Subsidiaries as such other party may select (at such other party’s expense). Any information obtained under this Section 7.06 shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or claims for refund or handling a Tax Action.

SECTION 7.07 Conveyance Taxes. Any Conveyance Taxes imposed in connection with the transactions contemplated by this Agreement shall be paid one-half by Sellers and one-half by Purchaser. The Sellers, after the review and consent by the Purchaser, shall file such applications and documents as shall permit any such Conveyance Taxes to be assessed and paid on or prior to the Closing in accordance with any available pre-sale filing procedure. The Purchaser shall execute and deliver all instruments and certificates necessary to enable the Sellers to comply with the foregoing. The Purchaser shall complete and execute a resale or other exemption certificate with respect to the inventory items sold hereunder, and shall provide the Seller with an executed copy thereof.

SECTION 7.08 Section 338(h)(10) Election. (a) Where permitted under applicable Law, Purchaser and Sellers agree to make a joint election under Sections 338(g) and 338(h)(10) of the Code with respect to the sale of the Shares under this Agreement for each Acquired Company and each of its Subsidiaries (together, the “Section 338(h)(10) Elections”). The Purchaser and the Sellers shall cooperate to identify the states and localities for which a Section 338(h)(10) Election would be made. At the Closing or, if the Purchaser and the Sellers identify a state or locality for which a Section 338(h)(10) Election would be made after the Closing, promptly after such identification, the Sellers shall deliver to the Purchaser an Internal Revenue Service Form 8023, Elections Under Section 338 for Corporations Making Qualified Stock Purchases, and any corresponding forms under comparable provisions of applicable state or local Law with respect to the Section 338(h)(10) Elections duly executed by Sellers. As requested from time to time by Sellers or Purchaser (whether before, at, or after the Closing), the Sellers and the Purchaser shall assist each other in, and shall provide the necessary information to each other, in connection with the preparation of any other forms and documentation required to effect valid and timely Section 338(h)(10) Elections. The Purchaser shall be responsible for the timely filing of the Section 338(h)(10) Elections with the appropriate Governmental Authorities and shall provide the Sellers with a copy of the Section 338(h)(10) Election forms as filed within five Business Days after filing. The Purchaser and the Sellers shall take all reasonably necessary steps and cooperate in good faith, including the exchange of information, to effect and preserve valid and timely Section 338(h)(10) Elections. Unless required by applicable Law, (1) each of the parties shall, and shall cause each of their respective Affiliates to, report, act and file all Tax Returns in a manner consistent with the Section 338(h)(10) Elections, and (2) no party shall take, or shall cause any of its Affiliates to take, any position that is inconsistent with the Section 338(h)(10) Elections.

(b) The Purchase Price shall be allocated among the Acquired Companies, and among the assets of the Acquired Companies, as of the Closing in determining “aggregate deemed sales price” and “adjusted gross-up basis” (as defined in the Code and Regulations) that results from the Section 338(h)(10) Elections in the manner described in this Section 7.08(b) (“Purchase Price Allocation”). Within 45 Business Days after the Closing, the Purchaser shall provide the Sellers with a proposed Purchase Price Allocation for the Sellers’ review and comment. If the Sellers do not provide any comments to the Purchaser in writing within 10 Business Days following delivery by the Purchaser of the proposed Purchase Price Allocation, then the Purchase Price Allocation proposed by the Purchaser shall be deemed to be final and binding absent manifest error. If, however, the Sellers submit comments to the Purchaser within such 10 Business Day period, the Purchaser and the Sellers shall negotiate in good faith to resolve any differences within 20 Business Days. The Sellers and the Purchaser agree that,

unless otherwise required by Law, the purchase and sale of the Acquired Companies will be reported for all Tax purposes in a manner that is consistent with the Purchase Price Allocation as finally agreed by the parties hereto, and that none of them (nor any of their respective Affiliates) will take any position inconsistent therewith on any Tax Return or otherwise. If the Sellers and the Purchaser are unable to reach agreement on the Purchase Price Allocation within such 20 Business Day period, then each of the Sellers and the Purchaser shall be responsible for determining its own Purchase Price Allocation for use on its Tax Returns in accordance with applicable Law.

SECTION 7.09 Miscellaneous. (a) The Sellers and the Purchaser agree to treat all payments made by either of them to or for the benefit of the other (including any payments to any Acquired Company or Subsidiary) under this Article VII, under other indemnity provisions of this Agreement and for any misrepresentations or breaches of warranties or covenants as adjustments to the Purchase Price or as capital contributions for Tax purposes and that such treatment shall govern for purposes hereof except to the extent that the Laws of a particular jurisdiction provide otherwise, in which case such payments shall be made in an amount sufficient to indemnify the relevant party on an after-Tax basis.

(b) All payments payable under any tax sharing agreement or arrangement between the Sellers and any Acquired Company or Subsidiary for any taxable period ending on or prior to the date of the Closing shall be calculated on a basis consistent with past practice and shall be payable in full prior to the Closing. Any such tax sharing agreement or arrangement between the Sellers and any Acquired Company or Subsidiary shall be terminated prior to the Closing.

(c) Notwithstanding any provisions in this Agreement to the contrary, the obligations of the Sellers to indemnify and hold harmless the Purchaser, the Acquired Companies and the Subsidiaries pursuant to this Article VII, and the representations and warranties dealing with Tax matters, including those contained in Section 3.24, shall terminate at the close of business on the 60th day following the expiration of the applicable statute of limitations with respect to the Tax liabilities in question (giving effect to any waiver, mitigation or extension thereof).

(d) Except as otherwise required by applicable Law and except for changes to comply with or adopt the provisions in the temporary regulations described in Revenue Procedure 2012-19, 2012-14 IRB 689 and Revenue Procedure 2012-20, 2012-14 IRB 700, from and after the date of this Agreement, the Sellers shall not, without the prior written consent of the Purchaser, make, or cause or permit to be made, any Tax election that would have an adverse effect on any Acquired Company or Subsidiary for any taxable period ending after the Closing Date.

(e) Except as otherwise required under applicable Law, or in settlement of a Tax audit or similar proceeding initiated by a Governmental Authority, none of Dycom, the Purchaser, their Affiliates, the Acquired Companies and Subsidiaries shall amend any Tax Return of the Acquired Companies or Subsidiaries with respect to a Pre-Closing Period or Straddle Period.

(f) Notwithstanding anything to the contrary in this Agreement, the rights and obligations of the parties with respect to indemnification for any and all Tax matters shall be governed solely by this Article VII and Section 9.02(c).

(a) the breach as of the date hereof or as of the Closing Date of any representation or warranty made by the Sellers contained in this Agreement or in any certificate delivered hereunder (it being understood that such representations and warranties (other than the Seller Fundamental Representations and clause (ii) of the first sentence of Section 3.12 and with respect to the scope of any disclosures required on the Disclosure Schedule) shall be interpreted without giving effect to any limitations or qualifications as to “materiality”, “Material Adverse Effect” or words of like meaning set forth therein);

Notwithstanding anything to the contrary contained in this Agreement, except with respect to claims relating to Taxes: (a) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to Section 9.02(a) or 9.03(a) (other than indemnification in respect of Seller Fundamental Representations or Purchaser Fundamental Representations, respectively) unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds $2.75 million whereupon the Indemnifying Party shall be liable for indemnification for the full amount of such Losses; (b) the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 9.02(a) or 9.03(a) (other than indemnification in respect of Seller Fundamental Representations or Purchaser Fundamental Representations, respectively), as the case may be, shall be an amount equal to 20% of the Purchase Price; (c) the maximum amount of

indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 9.02(a) or 9.03(a) for indemnification in respect of Seller Fundamental Representations or Purchaser Fundamental Representations, respectively, as the case may be, shall be an amount equal to the Purchase Price; (d) an Indemnifying Party shall not be liable for any Losses pursuant to Section 9.02(a) or 9.03(a), other than for indemnifiable Losses in excess of $20,000 resulting from a single claim or aggregate claims arising from the same facts, event or circumstances; (e) the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 9.02(b) or 9.03(b), as the case may be, shall be an amount equal to the Purchase Price; and (f) the Sellers shall have no Liability for any Losses in respect of the Purchaser’s Financing with respect to a breach of the representation and warranty contained in Section 3.08(b) other than taking such action as is necessary to make such representation and warranty accurate, and in any event the Sellers shall have no Liability for any such Losses relating to market conditions or market risk.

SECTION 9.05 Notice of Loss; Third Party Claims. (a) An Indemnified Party shall give the Indemnifying Party notice of any matter that an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within 30 days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises.

(b) If an Indemnified Party shall receive notice of any Action, audit, demand or assessment (each, a “Third Party Claim”) against it or which may give rise to a claim for Loss under this Article IX, promptly, but in no event later than 30 days after the receipt of such notice, the Indemnified Party shall give the Indemnifying Party notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article IX except to the extent that the Indemnifying Party is prejudiced by such failure and shall not relieve the Indemnifying Party from any other obligation or Liability that it may have to any Indemnified Party otherwise than under this Article IX. If the Indemnifying Party acknowledges in writing its obligation to indemnify the Indemnified Party hereunder against any Losses that may result from such Third Party Claim, then the Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if it gives notice of its intention to do so to the Indemnified Party within 30 days of the receipt of notice from the Indemnified Party of such Third Party Claim; provided, however, that if there exists a conflict of interest that the Indemnified Party’s outside counsel shall have advised the Indemnified Party would make it inappropriate for the same counsel to represent both the Indemnified Party and the Indemnifying Party, then the Indemnified Party shall be entitled to retain its own counsel in each jurisdiction for which the Indemnified Party so determines counsel is required, at the expense of the Indemnifying Party; provided, however, that the Indemnifying Party will not be required to pay the fees and disbursements of more than one counsel for all Indemnified Parties in any jurisdiction in any single Action. In the event that the Indemnifying Party exercises the right to undertake any such defense against any such Third Party Claim as provided above, the Indemnified Party shall cooperate with the Indemnifying Party in such defense and make

available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. If the Indemnifying Party elects to direct the defense of any such claim or proceeding, then the Indemnifying Party shall have the right to settle any Third Party Claim for which it obtains an unconditional release of the Indemnified Party from all liability in respect of such Third Party Claim or to which settlement the Indemnified Party consents in writing (not to be unreasonably withheld, conditioned or delayed). If, within 30 days after the receipt of the notice of such Third Party Claim, the Indemnifying Party does not notify the Indemnified Party that it elects to undertake the defense of such Third Party Claim, the Indemnified Party shall have the right to contest, settle or compromise such Third Party Claim but shall not thereby waive any right to indemnity therefor pursuant to this Agreement; provided, however, that no Indemnified Party may settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder under any circumstances without the prior written consent of the Indemnifying Party (not to be unreasonably withheld, conditioned or delayed), unless such settlement, compromise or consent includes an unconditional release of the Indemnifying Party from all liability arising out of such claim. In such event, the Indemnifying Party shall cooperate with the Indemnified Party in such defense and make available to the Indemnified Party, at the Indemnifying Party’s expense, all such witnesses, records, materials and information in the Indemnifying Party’s possession or under the Indemnifying Party’s control relating thereto as is reasonably required by the Indemnified Party. Notwithstanding anything in this Section 9.05 to the contrary, if a Third Party Claim relates to or arises in connection with any criminal Action or any Action seeking equitable or remedial relief, the Indemnified Party shall be entitled to jointly control the defense thereof with the Indemnifying Party for so long as such Action is continuing.

(c) The parties hereto acknowledge and agree that, except for the right to specifically enforce the provisions of this Agreement as provided in Section 11.10 and with respect to common law fraud (excluding any concept of “constructive fraud”), following the Closing, the provisions of Section 5.15, Article VII and this Article IX shall be the sole and exclusive remedies of the Seller Indemnified Parties and the Purchaser Indemnified Parties for any Loss and any and all claims arising under, out of, or related to this Agreement or the sale and purchase of the Acquired Companies and Subsidiaries, and no Person will have any other entitlement, remedy or recourse, whether in contract, tort or otherwise. In furtherance of the foregoing, each party hereby waives, to the fullest extent permitted under Law, any and all rights, claims and causes of action for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement it may have against the other parties hereto and their Affiliates and each of their respective officers, directors, employees, agents, successors and assigns arising under or based upon any Law, except pursuant to the indemnification provisions set forth in Article VII or this Article IX or the provisions in Section 5.15. The provisions of this Section 9.06, together with the limited remedies provided in Article VII and this Article IX, were specifically bargained for between Dycom, the Purchaser and the Sellers The Sellers have specifically relied upon the provisions of this Section 9.06, together with the limited remedies provided in Article VII and this Article IX, in agreeing to the Purchase Price and in agreeing to provide the specific representations and warranties set forth herein.

SECTION 9.06 Certain Other Indemnification Matters.

(a) The Losses giving rise to any indemnification obligation hereunder shall be reduced by any third party insurance proceeds or other payments actually received by the Indemnified Party in satisfaction of any such Losses net of reasonable expenses incurred in receiving such proceeds or payments (including any reasonably documented increase in insurance premiums that may arise in connection with the payment of any claim). Any Indemnified Party 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 reasonably may be entitled under insurance policies or indemnity, contribution or other similar agreements for any Losses.

(b) Notwithstanding any other provision of this Agreement, in no event shall any Indemnifying Party be liable to any Indemnified Party for any punitive damages (other than punitive damages actually paid in respect of a Third Party Claim) or loss of business reputation or opportunity, or any damages based on any type of multiple relating to the breach or alleged breach of this Agreement. Any liability for indemnification under this Agreement shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement. Each Indemnified Party shall take, and cause its Affiliates to take, all commercially reasonable steps to mitigate any Loss actually suffered by such party.

None of the parties hereto shall make, or cause to be made, any press release or public announcement in respect of this Agreement or the transactions contemplated hereby or otherwise communicate with any news media without the prior written consent of the other parties (not to be unreasonably withheld, conditioned or delayed) unless otherwise required by Law or applicable stock exchange rule or regulation (based upon the advice of counsel), and the parties hereto shall cooperate as to the timing and contents of any such press release, public announcement or communication.

All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in any New York federal court sitting in the Borough of Manhattan of The City of New York, provided, however, that if such federal court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any New York state court sitting in the Borough of Manhattan of The City of New York. Consistent with the preceding sentence, the parties hereto hereby (a) submit to the exclusive jurisdiction of any federal or state court sitting in the Borough of Manhattan of The City of New York for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto and (b) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated by this Agreement may not be enforced in or by any of the above named courts.

SECTION 11.12 Waiver of Jury Trial. Each of the parties hereto hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the transactions contemplated by this Agreement. Each of the parties hereto hereby (a) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it has been induced to enter into this Agreement and the transactions contemplated by this Agreement, as applicable, by, among other things, the mutual waivers and certifications in this Section 11.12.

SECTION 11.13 Currency. Unless otherwise specified in this Agreement, all references to currency, monetary values and dollars set forth herein shall mean United States (U.S.) dollars and all payments hereunder shall be made in United States dollars.

SECTION 11.14 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

SECTION 11.15 Non-Recourse. (a) All claims or causes of action (whether in contract or in tort, at law or in equity) that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement (including any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), may be made only against the entities that are expressly identified as parties hereto. No Person who is not a named party to this Agreement, including any director, officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney or representative of any named party to this Agreement (“Non-Party Affiliates”), shall have any liability (whether in contract or in tort, at law or in equity, or based upon any theory that seeks to impose liability of an entity party against its owners or affiliates) for any obligations or liabilities arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of this Agreement or its negotiation or execution; and each party hereto waives and releases all such liabilities, claims and obligations against any such Non-Party Affiliates. Non-Party Affiliates are expressly intended as third party beneficiaries of this provision of this Agreement.

(b) The Sellers and their respective Affiliates, directors, officers, employees, agents, partners, managers, members or stockholders shall not have any rights or claims against any of the commercial banks, investment banks or other financial institutions providing Financing to the Purchaser or Dycom in connection with the transactions contemplated by this Agreement (each a “Debt Financing Party”) in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including any dispute arising out of or relating in any way to the performance of any financing commitments or agreements of such Debt Financing Party with respect to the transactions contemplated hereby, whether at Law or equity, in contract, in tort or otherwise. No Debt Financing Party shall have any liability (whether in contract, in tort or otherwise) to the Sellers and their respective Affiliates, directors, officers, employees, agents, partners, managers, members or stockholders for any obligations or liabilities of any party hereto under this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby and thereby, including any dispute arising out of or relating in any way to the performance of any financing commitments of such Debt Financing Party with respect to the transactions contemplated hereby. Without limiting the foregoing, it is agreed that any claims or causes of action brought against any Debt Financing Party in its capacity as such will not be brought in any forum other than the federal and New York State courts located in the Borough of Manhattan within the City of New York and shall be governed by the law of the State of New York. It is further agreed that the Debt Financing Parties are intended third-party beneficiaries of, and shall be entitled to the protections of this Section 11.15(b).
