An amount equal to the Purchase Price minus the aggregate amount of the Closing Date Debt and the Transaction Payments (the “Net Purchase Price”) shall be payable, subject to the terms and conditions of this Agreement, by the Purchasers to the Partners as follows:

(a)    an amount equal to (i) the product of (A) thirty percent (30%) and (B) the Net Purchase Price minus (ii) the aggregate amount of the APR Stock Payments will be payable in shares of common stock of Quanta, par value $0.00001 (“Quanta Common Stock”) (the amount so payable is hereinafter referred to as the “Stock Consideration”), in a number equal to such amount divided by the Average Closing Price and issuable to the Partners as of the Closing in accordance with ‎Section 1.4; and

Notwithstanding anything to the contrary in this Agreement, the Purchasers may, in their sole discretion, elect to pay any or all of that portion of the Purchase Price to be paid by issuance of the Stock Consideration pursuant to ‎Section 1.2(a) in cash instead of Quanta Common Stock, in full satisfaction of any and all of the obligations of the Purchasers and Quanta in respect of such portion of the Stock Consideration and, if the Purchasers elect to exercise such right to pay any or all of such portion of the Purchase Price in cash: (i) that portion of the Purchase Price to be paid by the delivery of such portion of the Stock Consideration shall instead form part of the Cash Consideration and shall be subject to all of the provisions of this Agreement applicable to the Cash Consideration, mutatis mutandis, and; (ii) the Purchasers shall be under no obligation to deliver such portion of the Stock Consideration pursuant to this ‎Section 1.2, under ‎Section 1.4 or otherwise, and the provisions of ‎Section 3.5, ‎Section 5.2(k) and ‎Article IX shall no longer be applicable with respect to such portion of the Stock Consideration.

Section 1.5    Closing Date NWC.

(a)    The Purchasers shall, with the reasonable assistance of the Partners and the Partners Representative upon reasonable notice (so long as such Partners or the Partners Representative, as applicable, are employees of Quanta or one of its subsidiaries), provide to the Partners Representative as soon as reasonably possible (and, in any event, within ninety (90) days, which deadline may be extended by written agreement (including through electronic mail) of the Purchasers and the Partners Representative) after the Closing Date a statement (the “Closing Date NWC Statement”) that sets forth the Purchasers’ calculation of the Closing Date NWC (which may be positive or negative) together with a consolidated income statement and balance sheet for the Acquired Companies as of the Closing along with supporting documentation for applicable balance sheet accounts supporting that calculation. If the Purchasers do not deliver a Closing Date NWC Statement within such ninety (90) day period (as may be extended pursuant to Section 1.5(a)), then the Closing Date NWC shall be equal to the Estimated Closing Date NWC provided pursuant to Section 1.2 and shall be final, conclusive and binding on the Parties for all purposes of this Agreement.

(b)    The Purchasers shall provide the Partners Representative and his appropriate advisers with reasonable access during normal business hours to all books of account, other records and employees of the Acquired Companies that the Partners Representative may reasonably request to allow them to evaluate the Closing Date NWC Statement.

(c)    Within forty-five (45) days after the Closing Date NWC Statement is received by the Partners Representative from the Purchasers, the Partners Representative may give notice (a “NWC Dispute Notice”) to the Purchasers of any changes that he considers should be made to the Closing Date NWC Statement, setting out for each change:

(i)    reasonably supporting details of the change;

(ii)    a separate dollar value for the change; and

(iii)    details of the reasons why the Partners Representative believes the change should be made.

If the Purchasers do not receive a NWC Dispute Notice within such forty-five (45)-day period, then the Closing Date NWC shall be the amount set forth in the Closing Date NWC Statement and shall be final, conclusive and binding on the Parties for all purposes of this Agreement.

(d)    If the Partners Representative timely delivers a NWC Dispute Notice to the Purchasers, the Purchasers and the Partners Representative shall negotiate in good faith with a view to resolving their disagreements with respect to the Closing Date NWC. If the Purchasers and the Partners Representative resolve their disagreements with respect to the Closing Date NWC, the Closing Date NWC agreed upon by them shall be final, conclusive and binding on the Parties for all purposes of this Agreement. If the Purchasers and the Partners Representative are unable to resolve each of their disagreements with respect to the Closing Date NWC within fifteen (15) Business Days of the delivery of the NWC Dispute Notice, then either the Purchasers or the Partners Representative may deliver written notice to the other(s) (the “NWC Expert Notice”) requiring that such remaining disagreements be referred to Grant Thornton LLP or, if such firm is unable or unwilling to accept such role, a firm of appropriate reputation, standing, expertise and relevant experience in accounting or tax, as applicable, who shall be independent on such assignment and not then representing any Purchaser, Quanta or any Partner in any matter, as selected by mutual agreement of the Purchasers and the Partners Representative (the “Expert”). If Grant Thornton LLP is unable or unwilling to accept such role and the Purchasers and the Partners Representative fail to agree on the selection of the Expert within five (5) Business Days of the delivery of the NWC Expert Notice, the Purchasers shall promptly appoint a third party accountant representative and the Partners Representative shall promptly appoint a third party accountant representative and such accountants shall, within five (5) Business Days after their appointment, jointly select the Expert. The Purchasers and the Partners Representative shall instruct the Expert to (i) determine (A) the Closing Date NWC in accordance with this Agreement, including with respect to the definitions set forth in ‎Section 1.6 and (B) the allocation of costs and expenses in accordance with the last sentence of this ‎Section 1.5(d); (ii) notify the Purchasers and the Partners Representative of those determinations in writing as promptly as practicable after being appointed (but in any event within thirty (30) days of being appointed (or such other period as may be agreed between the Purchasers and the Partners Representative)); (iii) in making its determinations, apply United States generally accepted accounting principles (“GAAP”), but consistent with the provisions for determination of Closing Date NWC under this Agreement and applied on a basis consistent with the Financial Statements; (iv) limit its review and determination of the Closing Date NWC only to those matters set out in the NWC Dispute Notice which remain the subject of disagreement between the Purchasers and the Partners Representative; and (v) base its determination solely on the materials submitted by the Partners Representative and the Purchasers, without conducting any independent investigation. The Purchasers and the Partners Representative shall each promptly supply to the Expert any information, assistance and cooperation that the Expert may reasonably request in connection with such determination. All correspondence between the

Expert and the Purchasers or the Partners Representative (or their respective advisers) must be copied to the other Party. In resolving any disagreement with respect to the Closing Date NWC, the Expert may not assign a value to any such disputed item greater than the greatest value for such disputed item claimed by either the Purchasers, on the one hand, or the Partners Representative, on the other hand, or less than the smallest value for such disputed value for such disputed item claimed by either of them. The Purchasers and the Partners Representative shall instruct the Expert to make its determination within thirty (30) days after submission of the written positions. The Expert’s determination of the Closing Date NWC shall constitute an arbitral award that is final, conclusive and binding on the Parties for all purposes of this Agreement, non-appealable and upon which a judgment may be entered by a court having jurisdiction thereover. Notwithstanding anything to the contrary herein, the processes and procedures to be used by the Parties and the Expert in connection with the determination by the Expert of Closing Date NWC shall be limited to those set forth in this Agreement, and no other arbitration rules or procedures shall apply in connection therewith. The fees and disbursements of the Expert and the out-of-pocket costs and expenses (including reasonable fees and expenses of outside legal counsel) of the Parties relating to the disputes submitted to the Expert pursuant to this ‎Section 1.5(d) (collectively, the “NWC Dispute Expenses”) shall be borne (A) by the Partners on a several, and not joint, basis based on their respective Pro Rata Share, in that aggregate proportion equal to a fraction (expressed as a percentage), the numerator of which is equal to the Closing Date NWC proposed by the Partners Representative minus the Closing Date NWC determined by the Expert, and the denominator of which is equal to the Closing Date NWC proposed by the Partners Representative minus the Closing Date NWC proposed by the Purchasers and (B) by the Purchasers in that proportion equal to a fraction (expressed as a percentage), equal to one (1) minus the fraction described in clause (A). For example, if (x) the Partners Representative claims that the Closing Date NWC should be $10,000 and the Purchasers claim that the Closing Date NWC should be $8,000, (y) the Expert determines that the Closing Date NWC should be $9,200 and (z) the NWC Dispute Expenses are $100, then (A) each Partner shall be liable on a several, and not joint, basis for, and shall pay an amount equal to, its Pro Rata Share of forty percent (40%) of the NWC Dispute Expenses (i.e., an aggregate amount of $40) and (B) the Purchasers shall pay sixty percent (60%) of the NWC Dispute Expenses (i.e., an aggregate amount of $60).

Section 1.6    Definitions. The following definitions apply unless the context requires otherwise.

(a)    “Actual Deficit” means the amount (if any) by which (i) the Closing Date NWC (as finally determined pursuant to Section 1.5) is less than (ii) the sum of (A) the NWC Target plus (B) the Estimated Excess; provided, however, that notwithstanding anything to the contrary contained herein, if such amount is less than or equal to $1,000,000, then the Actual Deficit shall be deemed to equal $0.

(b)    “Actual Excess” means the amount (if any) by which (i) the Closing Date NWC (as finally determined pursuant to Section 1.5) is more than (ii) the sum of (A) the NWC Target plus (B) the Estimated Excess; provided, however, that notwithstanding anything to the contrary contained herein, if such amount is less than or equal to $1,000,000, then the Actual Excess shall be deemed to equal $0.

(c)    “Average Closing Price” means the average closing price per share of Quanta Common Stock for the ten (10) consecutive trading days ending on the trading day that is three (3) trading days prior to the Closing Date or the Earnout Payment Date, as applicable, as reported on The New York Stock Exchange (the “NYSE”).

(d)    “Closing Date Debt” means an aggregate amount equal to the current and non-current portions of the indebtedness set forth on Schedule 1.2, in the amount outstanding as of the Closing Date, including prepayment fees and penalties related to the payoff of any of the foregoing as of the Closing, and any outstanding obligations or liabilities of the Acquired Companies pursuant to or arising out of the APR Unit Agreements set forth on Schedule 1.2 (the “APR Unit Agreements”) or any other equity-based interest or instrument, in each case, whether or not such items are included as indebtedness or liabilities in accordance with GAAP and whether short-term or long-term.

(e)    “Net Working Capital” means the amount, on a consolidated basis, equal to:

(i)    the aggregate sum for the Acquired Companies of all (A) cash and cash equivalents, (B) Inventory, (C) accounts receivable (without any allowance for doubtful accounts) and (D) any other non-cash or non-cash equivalent assets properly classified as current assets (including, without duplication, any costs and estimated earnings in excess of billings and other unbilled revenues or prepaid expenses such as prepaid rent, security deposits, prepaid insurance premiums and subscriptions), less

(ii)    the aggregate sum for the Acquired Companies of all (A) current liabilities (including, without duplication, accounts payable, issued and outstanding checks and any other payment in process initiated on or prior to the Closing but not yet cleared by the applicable bank, accrued liabilities for Taxes, interest, warranty claims (including under Customer Contracts), payroll and other expenses incurred on or prior to the Closing, billings in excess of costs and estimated earnings and other deferred revenues, and loans payable to shareholders) and (B) current and non-current portions of bank and other indebtedness (including capital leases, whether or not reflected as such in the Financial Statements) to the extent such amounts in this clause (B) are not included in the Net Purchase Price calculation as Closing Date Debt in Section 1.2 above,

all as determined on an accrual basis in accordance with GAAP, but applied on a basis consistent with the Financial Statements (including using the completed contract method of accounting for purposes of revenue recognition).

Notwithstanding the foregoing, Net Working Capital shall not (x) other than accrued rent under related-party leases, include any amounts owed to or from the Acquired Companies by or to any of the Partners, any Affiliate of any Partner, or any person related (by blood, marriage, or otherwise) to any Partner, all of which amounts shall have been repaid or otherwise satisfied in full prior to the Closing, (y) take into account any (i) deferred Tax assets or liabilities established to reflect timing differences between book and Tax income or (ii) Transaction Payments paid at Closing, or (z) include accruals with respect to vacation time and bonuses (except, in the case of bonuses, to the extent that the

aggregate estimated bonus obligations exceed the prior year aggregate bonus payments).

(f)    “Transaction Payments” means, without duplication of any actual amounts included in the calculation of Closing Date Debt, the aggregate amount of any and all obligations of the Acquired Companies and the Partners actually payable as a result of or in connection with the negotiation, execution or consummation of the Acquisition under any success, termination, severance, assignment, change of control, sale bonus, incentive, retention, broker, finder, financial or legal advisor or other agreement, including any legal, accounting or other advisory fees and any Taxes related to any such obligations.

Section 1.7    Contingent Consideration.

(a)    Calculation. The Partners shall be entitled to receive additional consideration for the Acquired Interests (all such consideration and amounts, collectively the “Contingent Consideration”) based on the amount of Adjusted EBITDA generated by the Acquired Companies during the three-year period beginning on the day following the Closing and ending on July 31, 2020 (the “Earnout Period”), and any such Contingent Consideration shall be treated as an adjustment to the Purchase Price. If such Adjusted EBITDA exceeds the amount set forth on Schedule 1.7(a) under the heading “Earnout Threshold” during the Earnout Period, then the amount of Contingent Consideration paid by the Purchasers to the Partners Representative (on behalf of the Partners) shall be calculated as set forth on Schedule 1.7(a); provided, however, that in no event shall the aggregate Contingent Consideration exceed ONE HUNDRED MILLION DOLLARS ($100,000,000) regardless of the amount of such Adjusted EBITDA. For purposes of this ‎Section 1.7, the term “Adjusted EBITDA” shall be calculated in accordance with Schedule 1.7(b).

(b)    Lookback, Claims and Losses.

(i)    Notwithstanding anything to the contrary in this ‎Section 1.7, the calculation of Adjusted EBITDA for the Earnout Period that was delivered pursuant to Section 1.7(d) shall include a “lookback” analysis on each job in progress that is not completed as of the end of the Earnout Period which will compare the profit estimate as of the end of the Earnout Period for each such job to the latest available estimate of the profitability for such job, with any change in profitability for any such job resulting in a corresponding revision to Adjusted EBITDA (upwards or downwards). This lookback analysis will include, but not be limited to, an assessment of outstanding accounts receivable (and their collectability as determined in accordance with GAAP), costs and estimated earnings in excess of billings, unbilled revenues, billings in excess of costs and estimated earnings, deferred revenue and the earnings and profit margin recognized for such uncompleted jobs.

(ii)    In addition, to the extent that, either prior to or following the expiration of the Earnout Period (but in all cases within 180 days of the expiration of the Earnout Period), the Acquired Companies assert any claims or change orders related to activities occurring during the Earnout Period (less any out-of-pocket costs and expenses (including reasonable fees and expenses of outside legal counsel) of the Parties incurred in connection with the

collection thereof) (“Earnout Period Claims”), the value of such Earnout Period Claims shall be included in the determination of Adjusted EBITDA only to the extent such Earnout Period Claims are actually collected by the Acquired Companies and not repaid, returned or forfeited prior to the delivery of the Earnout Notice. Similarly, to the extent that, either prior to or following the expiration of the Earnout Period (but in all cases within 180 days of the expiration of the Earnout Period), any Person asserts any claims, counter-claims or other Losses against the Acquired Companies related to any activities occurring during the Earnout Period (plus any out-of-pocket costs and expenses (including reasonable fees and expenses of outside legal counsel) of the Parties incurred in connection therewith) (“Earnout Period Losses”), the calculation of Adjusted EBITDA shall be reduced by such Earnout Period Losses only to the extent such Earnout Period Losses are actually paid by the Acquired Companies prior to the delivery of the Earnout Notice.

(iii)    During the period beginning on the date of delivery of the Earnout Notice and ending on the date that is the first (1st) anniversary of the expiration of the Earnout Period (the “Earnout Deadline”), if the Earnout Period Claims that (A) were not included in the calculation of Contingent Consideration and (B) are actually collected or accrued (in accordance with GAAP), in each case, on or prior to the Earnout Deadline exceed the Earnout Period Losses that (1) were not included in the calculation of Contingent Consideration and (2) are actually paid or accrued (in accordance with GAAP), in each case, on or prior to the Earnout Deadline (such excess, the “Earnout Claims Excess”), then an amount equal to the Earnout Claims Excess shall be added to Adjusted EBITDA for purposes of calculating Contingent Consideration, with any amounts payable as a result thereof being treated as a payment of additional Contingent Consideration. Alternatively, if the Earnout Period Losses that (x) were not included in the calculation of Contingent Consideration and (y) are actually paid or accrued (in accordance with GAAP), in each case on or prior to the Earnout Deadline, exceed the Earnout Period Claims that (I) were not included in the calculation of Contingent Consideration and (II) are actually collected or accrued (in accordance with GAAP), in each case on or prior to the Earnout Deadline (such excess, the “Earnout Loss Excess”), then an amount equal to the Earnout Loss Excess shall be deducted from Adjusted EBITDA for purposes of calculating Contingent Consideration. The Parties shall promptly notify each other upon becoming aware of any potential Earnout Period Claims or Earnout Period Losses. Within thirty (30) days following the Earnout Deadline, the Purchasers shall deliver or cause to be delivered to the Partners Representative a statement that sets forth the Purchasers’ calculation of the Earnout Claims Excess or Earnout Loss Excess (as applicable) together with itemized schedules supporting that calculation (the “Final Earnout Notice”). After receipt of the Final Earnout Notice, the Partners Representative shall have thirty (30) days to review such notice, and if the Partners Representative delivers written notice to the Purchasers within such thirty (30) day period stating that the Partners Representative objects to such calculation and specifying in reasonable detail the basis for such objection and the dollar amount of such disputed items, the Partners Representative and the Purchasers will negotiate in good faith with a view to resolving their disagreements with respect to, and finally determine and agree upon, such disputed items as promptly

as practicable. If the Purchasers and the Partners Representative resolve their disagreements with respect to such disputed items, the amount of the Earnout Claims Excess or Earnout Loss Excess (as applicable) agreed upon by them shall be final, conclusive and binding on the Parties for all purposes of this Agreement. If the Partners Representative does not deliver notice of any such dispute within such thirty (30) day period, then the Partners Representative shall be deemed to have accepted and agreed to the amount of the Earnout Claims Excess or Earnout Loss Excess (as applicable) set forth in such statement delivered by the Purchasers pursuant to this Section 1.7(b)(iii). If the Partners Representative timely delivers notice of any such dispute and the Partners Representative and the Purchasers are unable to agree upon the amount of the Earnout Claims Excess or Earnout Loss Excess (as applicable) within fifteen (15) days of the delivery of such objection notice, then the Parties shall resolve such dispute in accordance with the procedures set forth in ‎Section 1.7(e)(iii). Upon final determination of the Earnout Claims Excess or Earnout Loss Excess (as applicable) in accordance with the foregoing, if such amount would (i) result in additional Contingent Consideration, such additional amount shall be paid by the Purchasers in accordance with Section 1.7(c); or (ii) result in a reduction in Contingent Consideration following the prior payment of Contingent Consideration pursuant to the terms of this Agreement, each Partner shall be liable on a several, and not joint, basis for, and shall pay to the Purchasers, its Pro Rata Share of an amount in cash equal to such reduction (an “Earnout Deficit”), in each case within five (5) Business Days of the final determination of such amount.

(c)    Form of Payment. Any Contingent Consideration owed to the Partners pursuant to this ‎Section 1.7 shall be paid by the Purchasers as follows: (i) seventy percent (70%) in the form of cash, paid by wire transfer of immediately available funds to such accounts designated in writing by the Partners Representative, including wire transfer instructions (all such cash amounts, the “Contingent Cash Consideration”), and (ii) thirty percent (30%) in the form of shares of Quanta Common Stock (all such shares, the “Contingent Stock Consideration”), as further provided in ‎Section 1.8. Notwithstanding anything to the contrary in this Agreement, if the Purchasers owe any Contingent Stock Consideration pursuant to the terms of this ‎Section 1.7, the Purchasers may, in their sole discretion, elect to pay any or all of the Contingent Stock Consideration in cash instead of shares of Quanta Common Stock in full satisfaction of any and all of the obligations of the Purchasers and Quanta in respect of such Contingent Stock Consideration and, if the Purchasers elect to exercise such right to pay any or all of the Contingent Stock Consideration in cash: (A) that portion of such Contingent Stock Consideration shall instead form part of the Contingent Cash Consideration and shall be subject to all of the provisions of this Agreement applicable to the Contingent Cash Consideration, mutatis mutandis; (B) the Purchasers shall be under no obligation to deliver such portion of the Contingent Stock Consideration pursuant to this ‎Section 1.7, under ‎Section 1.8 or otherwise, and the provisions of ‎Section 3.5, ‎Section 5.2(k) and ‎Article IX shall no longer be applicable with respect to such portion of the Contingent Stock Consideration; and (C) the Purchasers’ decision to pay any or all of such portion of the Contingent Consideration in cash shall be independent of the

Purchasers’ decision to pay in cash any other portion of the Purchase Price otherwise payable in shares of Quanta Common Stock.

(d)    Earnout Notice. Within one hundred eighty (180) days following the end of the Earnout Period, the Purchasers shall deliver or cause to be delivered to the Partners Representative the consolidated balance sheet and income statement of the Acquired Companies for the Earnout Period, specifying the Purchasers’ calculation of the Acquired Companies’ Adjusted EBITDA for the Earnout Period and showing in reasonable detail the computation thereof (including any equitable adjustments pursuant to ‎Section 1.7(f)) and, based thereon, the Purchasers’ calculation of the amount of Contingent Consideration to be paid pursuant to ‎Section 1.7(a) (the “Earnout Notice”).

(e)    Right to Inspect Books and Records; Earnout Dispute Resolution.

(i)    After receipt of the Earnout Notice, the Partners Representative shall have thirty (30) days to review such Earnout Notice (the “Earnout Notice Review Period”). During the Earnout Notice Review Period, the Purchasers shall (A) provide the Partners Representative and his authorized representatives, upon reasonable notice, reasonable access during normal business hours to the books, records and employees of the Acquired Companies (subject to the Partners Representative and his representatives entering into customary confidentiality and access agreement(s) as appropriate), in order for them to review the method of preparation of the Earnout Notice and (B) cooperate with the Partners Representative and his authorized representatives, including the provision on a timely basis of information reasonably requested by the Partners Representative or his authorized representatives and necessary in reviewing the preparation of such Earnout Notice.

(ii)    If the Partners Representative delivers written notice (an “Earnout Dispute Notice”) to the Purchasers within the Earnout Notice Review Period stating that the Partners Representative objects to any item in such Earnout Notice, specifying in reasonable detail the basis for such objection and the dollar amount of such disputed items, the Partners Representative and the Purchasers will negotiate in good faith with a view to resolving their disagreements with respect to, and finally determine and agree upon, such disputed item as promptly as practicable. If the Purchasers and the Partners Representative resolve their disagreements with respect to such disputed items, the amount of the Acquired Companies’ Adjusted EBITDA for the Earnout Period and, based thereon, the calculation of the amount of Contingent Consideration to be paid pursuant to ‎Section 1.7(a) agreed upon by them shall be final, conclusive and binding on the Parties for all purposes of this Agreement. If the Partners Representative does not deliver an Earnout Dispute Notice to the Purchasers within the Earnout Notice Review Period, then the Partners Representative shall be deemed to have accepted and agreed to the amount of Adjusted EBITDA and Purchasers’ calculation of the Contingent Consideration to be paid pursuant to ‎Section 1.7(a) set forth in the Earnout Notice.

(iii)    If the Partners Representative and the Purchasers are unable to agree upon the Contingent Consideration within fifteen (15) days of the delivery of the Earnout Dispute Notice, then either the Purchasers or the Partners Representative may deliver written

notice to the other(s) (the “Earnout Expert Notice”) requiring any remaining disputed items with respect to the Contingent Consideration be referred to the Expert, as selected in the manner provided in Section 1.5(d). Within five (5) Business Days of the delivery of the Earnout Expert Notice, each Party shall submit its written position with respect to such items remaining in dispute to the Expert. The Expert shall address only those disputed numerical inaccuracies and errors in the calculation of Adjusted EBITDA and may not determine a Contingent Consideration greater than the greatest amount claimed by the Partners Representative or smaller than the smallest amount claimed by the Purchasers. The Expert’s review and determination shall be limited to only those items remaining in dispute and base such determination solely on the materials submitted by the Partners Representative and the Purchasers, without conducting any independent investigation. The Purchasers and the Partners Representative shall each promptly supply to the Expert any information, assistance and cooperation that the Expert may reasonably request in connection with such determination. All correspondence between the Expert and the Purchasers or the Partners Representative (or their respective advisers) must be copied to the other Party. The Purchasers and the Partners Representative shall instruct the Expert to make its determination in writing as promptly as practicable after being appointed pursuant to this Section 1.7(e)(iii) (but in any event within thirty (30) days of such appointment) (or such other period as may be agreed between the Purchasers and the Partners Representative). The Expert’s determination pursuant to this Section 1.7(e)(iii) shall constitute an arbitral award that is final, conclusive and binding on the Parties for all purposes of this Agreement, non-appealable and upon which a judgment may be entered by a court having jurisdiction thereover. Notwithstanding anything to the contrary herein, the processes and procedures to be used by the Parties and the Expert in connection with the determination by the Expert of Adjusted EBITDA shall be limited to those set forth in this Agreement, and no other arbitration rules or procedures shall apply in connection therewith. The fees and disbursements of the Expert and the out-of-pocket costs and expenses (including reasonable fees and expenses of outside legal counsel) of the Parties relating to the disputes submitted to the Expert pursuant to this Section 1.7(e)(iii) (collectively, the “Earnout Dispute Expenses”) shall be borne (A) by the Partners, on a several, and not joint, basis based on their respective Pro Rata Share, in that aggregate proportion equal to a fraction (expressed as a percentage), the numerator of which is equal to the Contingent Consideration claimed by the Partners Representative minus the Contingent Consideration determined by the Expert, and the denominator of which is equal to the Contingent Consideration claimed by the Partners Representative minus the Contingent Consideration claimed by the Purchasers and (B) by the Purchasers in that proportion equal to a fraction (expressed as a percentage) equal to one (1) minus the fraction described in clause (A). For example, if (x) the Partners Representative claims that the Contingent Consideration should be $10,000 and the Purchasers claim that the Contingent Consideration should be $8,000, (y) the Expert determines that the Contingent Consideration should be $9,200 and (z) the Earnout Dispute Expenses are $100, then (A) each Partner shall be liable on a several, and not joint, basis for, and shall pay an amount equal to, its Pro Rata Share of forty percent (40%) of the Earnout Dispute Expenses (i.e., an aggregate amount of $40) and (B) the Purchasers shall pay sixty percent (60%) of the Earnout Dispute Expenses (i.e., an aggregate amount of $60).

(iv)    Payment of the Contingent Consideration, if any, shall be made within five (5) Business Days after such amount has been finally determined in accordance with this ‎Section 1.7 and ‎Section 1.8 (the “Earnout Payment Date”) and pursuant to a written notice of payment (the “Earnout Payment Notice”), which shall include, with respect to the Contingent Stock Consideration, (A) the calculation of the Contingent Stock Consideration, including the calculation of the Average Closing Price and the number of shares comprising the Contingent Stock Consideration, and (B) the portion of the Contingent Stock Consideration payable to each Partner on the Earnout Payment Date.

(f)    Post-Closing Operation of the Acquired Companies.

(i)    The Parties acknowledge and agree that, from and after the Closing Date, the management and operations of the Acquired Companies and their businesses will be at Quanta’s sole discretion and that, subject to the other provisions of this Agreement, including Section 1.7(f)(iii), neither Quanta nor the Purchasers shall have any obligation to operate the Acquired Companies in order to achieve any Contingent Consideration or to maximize the amount of any Contingent Consideration.

(ii)    Each of the Parties acknowledge that (A) the future performance of the Acquired Companies is subject to significant business, economic and competitive uncertainties and contingencies, (B) actual results of the Acquired Companies may vary from anticipated results and (C) there is no assurance that the Company will achieve any particular level of Adjusted EBITDA. Accordingly, except as expressly provided by this Agreement, none of the Parties or their respective Affiliates or their respective directors, officers, employees or agents makes any representations or warranties, express or implied, with respect to any Contingent Consideration or the future performance, prospects, financing or operations of the Acquired Companies, including any future Adjusted EBITDA. The Parties acknowledge that, except as expressly provided by this Agreement, the Purchasers have not promised or projected any Contingent Consideration, and the Parties solely intend the express provisions of this Agreement to govern this contractual relationship.

(iii)    To the extent that (A) Quanta or the Purchasers cause the Acquired Companies to be operated substantially outside the ordinary course of business and inconsistent with past practices of the Acquired Companies, (B) Quanta or the Purchasers cause any of the Acquired Companies to transfer or sell material assets (including employees or personnel) substantially outside the ordinary course of business and inconsistent with past practices of such applicable Acquired Company or (C) Quanta, the Purchasers, any of the Acquired Companies or any of their respective Affiliates divert to other Affiliates of Quanta business opportunities originated by any of the Acquired Companies or work completed by the employees or personnel of the Acquired Companies for which the Acquired Companies have the capacity and ability to perform and, in the case of any of clause (A), (B) or (C), such actions result in a material deviation to the Adjusted EBITDA of the Acquired Companies that is used to calculate the Contingent Consideration, if any, that is payable pursuant to this Agreement (any such actions, an “Earnout Adjustment Action”), then the Purchasers shall

include in the Earnout Notice or the Final Earnout Notice, as applicable, a proposed equitable adjustment to the Contingent Consideration in favor of the Partners to take appropriate account of the change to the Adjusted EBITDA as a result of such Earnout Adjustment Action, it being agreed that with respect to clause (A) above, such equitable adjustment shall only result in the gain or loss associated with such Earnout Adjustment Action being excluded from the determination of Adjusted EBITDA with no other adjustment.

(iv)    Notwithstanding the foregoing, no equitable adjustment to the Contingent Consideration shall be made (A) to the extent an Earnout Adjustment Action is taken to comply with any Applicable Law; (B) in respect of any change or expansion of the Acquired Companies’ activities with respect to its existing business lines or any new business lines, in each case that are consistent with the Acquired Companies’ business plans as of immediately before Closing; or (C) where the Partners Representative has actual knowledge (and not simply reason to believe) of an actual Earnout Adjustment Action (including where an Acquired Company has taken affirmative action with potential third parties (including preliminary meetings with any such third parties) in pursuit of an Earnout Adjustment Action) and has not provided written notice to Quanta stating in reasonable detail his objection to such Earnout Adjustment Action (an “Earnout Adjustment Notice”) within thirty (30) days of the Partners Representative having such actual knowledge.

(g)    Tax Treatment. The Parties agree to treat any Contingent Consideration paid by the Purchasers to the Partners pursuant to this ‎Section 1.7 as additional consideration paid for the purchase of Acquired Interests pursuant to this Agreement for all applicable Tax purposes, and no Party shall take a position on any Tax Return or other filings, or its books and records, that is inconsistent with this treatment, unless required by a change of Applicable Law effective after the date of this Agreement or a determination of a Governmental Entity that is final; provided that a portion of Contingent Consideration shall be treated as interest as required by U.S. Treasury Regulation Section 1.1275-4(c) Code and Section 1274 (and the other applicable provisions of the Code or other applicable Tax laws) using the discount rate specified therein to determine the imputed interest.

(h)    Non-Transferable; Non-Assignable; Contract Right. The right to receive the Contingent Consideration shall not be represented by any form of certificate or other instrument, is not assignable or transferable by any Partner (other than any transfer to an individual’s or trust’s heirs, beneficiaries, successors, assigns or personal representatives upon the death of such individual, by operation of law, will, intestate succession or otherwise) and may not be pledged or encumbered by any Partner. The right to receive the Contingent Consideration is a contractual right only and does not constitute an equity or ownership interest in the Acquired Companies, the Purchasers or Quanta. A holder of a right to receive the Contingent Consideration, in such capacity, shall not be deemed to be a stockholder, member or partner of the Acquired Companies, the Purchasers or Quanta, or have the right to vote, notice or any other rights of a stockholder, member or partner. It is not the intention of the parties to create, nor shall this ‎Section 1.7 be deemed or construed to create, a partnership, joint venture or association, or a trust or other fiduciary relationship.

(i)    Forfeiture of Contingent Consideration. In addition to, and without limitation of, the Purchasers’ rights under ‎Article VIII, payment of the Contingent Consideration is expressly conditioned upon and subject to compliance by the Partners of their obligations under ‎Section 4.4, and the material failure by any Partner to comply with such obligations shall release the Purchasers from any further liability or obligation to make any payments in respect of any Contingent Consideration to such Partner and any Contingent Consideration then or thereafter due and payable by the Purchasers hereunder shall be reduced by such Partner’s Contingent Consideration Pro Rata Share.

(j)    Annual Estimates. Within thirty (30) days after the filing of Quanta’s Annual Report on Form 10-K with the U.S. Securities and Exchange Commission (“SEC”) relating to a fiscal year completed during the Earnout Period, the Purchasers shall deliver or cause to be delivered to the Partners Representative an estimate of the Adjusted EBITDA of the Acquired Companies for the applicable portion of the Earnout Period, calculated by the Purchasers as set forth in this Section 1.7. For the avoidance of doubt, such estimated Adjusted EBITDA shall not be binding upon the Parties and shall not otherwise alter, limit or restrict the rights and obligations of the Parties under this ‎Section 1.7.

(k)    Earnout Trigger Event. In the event of the occurrence of any of the following (an “Earnout Change in Control Event”) during the Earnout Period: (i) a Change in Control of Quanta and, within one (1) year of such Change in Control, the Chief Executive Officer of Quanta (or of the then-existing ultimate parent entity of Quanta immediately prior to such Change in Control) at the time of such Change in Control ceases to be employed in such officer’s current or higher position by Quanta (or then-existing ultimate parent entity of Quanta immediately prior to such Change in Control) or (ii) a Change in Control of the Acquired Companies, then the Partners shall be entitled to receive, and the Purchasers and Quanta shall pay, or cause to be paid to the Partners Representative (on behalf of the Partners), an aggregate amount equal to the sum of (x) the calculation of the Contingent Consideration for the completed interim period of the Earnout Period commencing on the first date of the Earnout Period and ending on the effective date of the Change in Control underlying such Earnout Change in Control Event) and (y) the pro rata portion of the Contingent Consideration attributable to the remainder of the Earnout Period following the effective date of the Change in Control underlying such Earnout Change in Control Event, in each case, as calculated in accordance with Schedule 1.7(k) and without any regard to the amount of the Adjusted EBITDA earned by the Acquired Companies in such period; provided, however, that with respect to clause (i) above, if Quanta is not the continuing or surviving entity immediately after such Change in Control, any Contingent Stock Consideration payable pursuant to this Section 1.7 shall be payable in publicly-traded securities of the Person who following such Change in Control, will own or control the voting securities or the assets and properties referenced in the definition of Change in Control below, or if such securities are not so publicly traded, in cash. For purposes hereof, a “Change in Control” shall mean, (1) with respect to Quanta, (A) an event or series of events by which any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of in excess of fifty percent (50%) of the capital stock of Quanta entitled to vote for members of the board of directors or equivalent governing body of Quanta (“Voting Stock”); and (B) a sale of all or substantially all of the assets and properties of Quanta and its subsidiaries, taken

as a whole, to a Person other than to an Affiliate of Quanta; and (2) with respect to the Acquired Companies, in a single or series of related transactions, (A) a direct or indirect sale of the equity interests in one or more of the Acquired Companies that hold all or substantially all of the assets of the Acquired Companies, taken as a whole, or (B) a sale of all or substantially all of the assets of the Acquired Companies, taken as a whole, in the case of each of clause (A) or (B), to a Person other than an Affiliate of Quanta. For the avoidance of doubt, a transaction will not be deemed to involve a “Change in Control” with respect to Quanta if (x) Quanta becomes a direct or indirect wholly-owned Subsidiary of a Person or directly or indirectly sells, transfers, conveys or otherwise disposes of all or substantially all of the assets and properties of Quanta to such Person or a Wholly-Owned Subsidiary thereof and (y)(i) the holders of the Voting Stock of such Person immediately following that transaction are substantially the same as the holders of Quanta’s Voting Stock immediately prior to that transaction or (ii) both (x) the holders of Quanta’s Voting Stock immediately prior to that transaction beneficially own, directly or indirectly, more than 50% of the Voting Stock of such Person, measured by voting power rather than number of shares, immediately following such transaction and (y) no person or group (other than a holding company satisfying the requirements of this sentence) becomes the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such Person, measured by voting power rather than number of shares, immediately following such transaction.

Section 1.8    Payment of Contingent Stock Consideration.

(a)    If any Contingent Stock Consideration is payable pursuant to ‎Section 1.7, Quanta, on behalf of the Purchasers, shall deliver or cause to be delivered to the Partners, subject to and conditioned upon the respective Partner’s timely providing Quanta all information as required pursuant to ‎Section 5.2(k) a copy of an instruction letter to Quanta’s transfer agent, duly executed by an authorized Quanta signatory, directing that the Contingent Stock Consideration be issued in book-entry form in the name of the respective Partners.

(b)    No fractional shares of Quanta Common Stock shall be issued as Contingent Stock Consideration, and each Partner shall be entitled to receive the nearest whole share of Quanta Common Stock rounded upwards, without reducing the amount of the Contingent Cash Consideration payable pursuant to this Agreement.

Section 1.9    Withholding Taxes. All payments and other consideration due to the Partners under this Agreement shall be made net of any applicable deduction or withholding for or on account of any Tax. If Quanta or the Purchasers determine that withholding is required pursuant to this Section 1.9, Quanta, the Purchasers, the Acquired Companies or any other applicable withholding agent, prior to deducting and withholding any amounts pursuant to this Section 1.9, shall notify the Person in respect of which such deduction or withholding will be made of such determination, with reasonable specificity. In the event Quanta or the Purchasers are required to withhold or deduct an amount for or on account of any Tax from any payment or other consideration due to the Partners under this Agreement and such amount is paid over to the appropriate Governmental Entity, the amount deducted or withheld shall be treated as paid to the person on whose behalf the amount is deducted or withheld for all purposes of this Agreement.

Section 1.10    Purchase Price Allocation. The amount of the Purchase Price (excluding any amount of the Escrow Funds and Contingent Consideration treated as interest for U.S. federal income tax purposes) plus the aggregate amount of all liabilities of the Acquired Companies that are treated for U.S. federal income tax purposes as consideration received by the Partners in the Acquisition (collectively, the “Amount Realized”) shall be allocated among the assets of the Acquired Companies for purposes of Section 751 of the Code and the statement required to be filed under Treas. Reg. § 1.751-1(a)(3) (and any similar provision of state, local or foreign Applicable Law, as applicable) (the “Allocation”). The Partners Representative shall provide Quanta with any information reasonably requested and required to prepare the Allocation. Quanta shall complete a draft Allocation and shall furnish the Partners Representative with a copy (the “Draft Allocation”) within sixty (60) days after the date on which the Closing Date NWC becomes final pursuant to ‎Section 1.5. Unless the Partners Representative provides written notice to Quanta of any objections to the Draft Allocation within thirty (30) days after receipt thereof, the Draft Allocation shall become final (the “Final Allocation”); provided that, in the event the Amount Realized is subsequently adjusted as a result of this Agreement, Quanta shall prepare and furnish to the Partners Representative a revised Draft Allocation and the revised Draft Allocation shall become the Final Allocation unless the Partners Representative provides written notice to Quanta of any objections to such revised Draft Allocation within thirty (30) days after receipt thereof. If the Partners Representative timely provides written notice of objection to the Draft Allocation pursuant to the prior sentence, Quanta and the Partners Representative shall negotiate in good faith to resolve such objection(s). In the event Quanta and the Partners Representative fail to resolve such objection(s) within fifteen (15) days after delivery of the Partners Representative’s notice, either Quanta or the Partners Representative may deliver written notice to the other stating the intent to submit such dispute to the Expert, and within fifteen (15) Business Days of such notice, each Party shall submit its written position with respect to the items in dispute to the Expert for resolution under procedures similar to those described in ‎Section 1.7(e)(iii). Quanta shall bear fifty percent (50%) of the fees of the Expert for resolution of any dispute under this ‎Section 1.10, and each Partner shall be liable on a several, and not joint, basis for, and shall pay an amount equal to, its Pro Rata Share of the remainder of such fees. Upon the resolution of all disputed items with respect to the Draft Allocation pursuant to the foregoing procedures, the Draft Allocation shall become the Final Allocation. The Parties shall consistently report the Final Allocation for all Tax purposes, and shall not take or assert any position inconsistent therewith for any Tax purpose except to the extent required by Applicable Laws.

Each of the Partners hereby, severally and not jointly, represents and warrants to each of the Purchasers and Quanta that the statements contained in this Article II are true and correct as of the Closing Date. In addition, each of the Partners hereby acknowledges that the Purchasers and Quanta are relying on the representations and warranties set forth in this ‎Article II in connection with their execution and delivery of this Agreement and in completing the transactions contemplated by this Agreement.

Section 2.1    Organization. Each of the General Partners and the Acquired Companies is a limited partnership or limited liability company, as applicable, duly formed, validly existing and in

The Partners have heretofore delivered or otherwise made available, to the extent such records exist, to the Purchasers or Quanta true, correct and complete copies of the Organizational Documents and record books of each Acquired Company as currently in effect (including the record books of each Acquired Company with respect to all actions taken by such Acquired Company’s general partner, limited partners, manager or board of managers or board of directors, including any committee thereof, and the Partners). Schedule 2.1 sets forth each Acquired Company’s jurisdiction of formation, description of the type of entity and all of the jurisdictions in which it is qualified or registered to do business.

Section 2.2    Authorization. Such Partner and, as applicable, each Acquired Company has full power, capacity and authority to enter into, execute and deliver this Agreement and any other certificate, agreement, document or other instrument to be executed and delivered by such Person in connection with the transactions contemplated by this Agreement (collectively, the “Partner Ancillary Documents”) and to perform such Person’s obligations under this Agreement and the Partner Ancillary Documents to which such Person is a party and to consummate the transactions contemplated hereby and thereby. This Agreement has been, and the Partner Ancillary Documents to which such Person is a party will be as of the Closing Date, duly executed and delivered by such Partner and the Acquired Companies, as applicable, and (assuming the due authorization, execution and delivery thereof by each other party thereto) constitute, or will constitute, as the case may be, legal, valid and binding agreements of such Partner and the Acquired Companies, as applicable, enforceable against each of them, as applicable, in accordance with their respective terms, subject to applicable bankruptcy, insolvency and other similar laws affecting the enforceability of creditors’ rights generally, general equitable principles and the discretion of courts in granting equitable remedies.

Section 2.3    Investments and Subsidiaries.

Section 2.6    Real Property.

(a)    Owned Real Property. No Acquired Company owns any real property or is a party to any contracts, agreements or commitments or has any other obligations for the purchase or acquisition of fee simple title to any real property or for the purchase or construction of any buildings.

(b)    Leased Real Property. Schedule 2.6 sets forth a true and complete list of the Real Property Leases (the parcels of real property covered by such Real Property Leases, together with all rights, title and interest of each Acquired Company in and to the leasehold improvements relating thereto, including security deposits, reserves or prepaid rents paid in connection therewith, any easements and other rights and appurtenances thereto and whether any such lease is subject to an oral, rather than written, lease agreement, the “Leased Real Property”). Except as set forth on Schedule 2.6, there are no oral agreements related to the leasing of Leased Real Property. Each Acquired Company that is party to a Real Property Lease has a valid, binding and enforceable leasehold interest in each applicable Leased Real Property, such leasehold interest being free and clear of any Liens other than Permitted Liens. The Leased Real Property constitutes and includes all interests in real property currently used or held for use in connection with the business of the Acquired Companies and that is necessary for the continued operation of the business of the Acquired Companies as currently conducted. No Acquired Company has used, or allowed any other Person to use, any Leased Real Property for any purpose other than the operation of the business of such Acquired Company in the ordinary course.

(c)    Real Property Lease Agreements. The Partners have heretofore delivered to the Purchasers or Quanta true, correct and complete copies of the agreements, instruments and documents related to the leasing of the Leased Real Property, together with all amendments, modifications and supplements, if any, thereto (the “Real Property Leases”). Schedule 2.6 also identifies with respect to each of the Real Property Leases: (i) the identity of the landlord and tenant, (ii) the current expiration date of the Real Property Lease or if such Real Property Lease is operated on a month-to-month basis, (iii) the current annual or monthly rental payment, as applicable, and (iv) the location of the Leased Real Property. No Acquired Company has sent or received any written notice of assessments, including threatened or otherwise, general or specific, which have been or are in the process of being levied against any of the Leased Real Property under any of the Real Property

Leases. Each Acquired Company party to any Real Property Lease has peaceful and undisturbed possession with respect to the Leased Real Property under which such Acquired Company is the lessee, sublessee, licensee, user or occupant. With respect to each Real Property Lease: (1) no Acquired Company is in breach or default under such Real Property Lease, and no event has occurred or circumstance exists which, with the delivery of notice, passage of time or both, would constitute such a breach or default by any Acquired Company or any Related Party or, to the Knowledge of the Partners, any other party thereto, and the applicable Acquired Company has paid all rent due and payable through the Closing Date under such Real Property Lease; (2) no Acquired Company has, and none of the Partners have, received or given any notice of any default or event that with notice or lapse of time, or both, would constitute a default by any Acquired Company or any Related Party under the Real Property Lease and, to the Knowledge of the Partners, no other party is in default thereof, and no party to any Real Property Lease has exercised any termination rights with respect thereto; (3) no Acquired Company has subleased, assigned or otherwise granted the right to use or occupy the Leased Real Property or any portion thereof to any Person (other than to another Acquired Company); (4) no Acquired Company has pledged, mortgaged or otherwise granted a Lien on its leasehold interest in any Leased Real Property that will not be extinguished at Closing; (5) no Acquired Company has waived in writing any of its rights under any Real Property Leases; and (6) except as described in Schedule 2.6, with respect to Leased Real Property (i) leased under a lease which is not an Existing Related Party Lease, to the Knowledge of the Partners, and (ii) leased from a landlord which is a Related Party (each such lease, an “Existing Related Party Lease”), there are no non-disturbance agreements, lessor forbearance agreements, lessor waiver agreements or similar agreements affecting the Real Property Lease.

(d)    Real Property Compliance with Laws. All authorizations and consents necessary in connection with the Acquired Companies’ present use and operation of the Leased Real Property, and the lawful occupancy thereof, have been issued by the applicable Governmental Entity. With respect to Leased Real Property (i) leased under a lease which is not an Existing Related Party Lease, to the Knowledge of the Partners, and (ii) leased under an Existing Related Party Lease, no portion of the Leased Real Property, or any of the respective buildings and improvements located thereon, violates any Applicable Laws in any material respect, including those relating to zoning, building, land use, environmental, health and safety, fire, air, sanitation and noise control. With respect to Leased Real Property (i) leased under a lease which is not an Existing Related Party Lease, to the Knowledge of the Partners, and (ii) leased under an Existing Related Party Lease, none of the Leased Real Property is subject to any judgment, decree, order, injunction, award or ruling, whether threatened or proposed of a Governmental Entity to be sold or taken by public authority. None of the Acquired Companies or the Partners have received any written notice of (1) any violation of building codes and/or zoning ordinances or other governmental or regulatory laws affecting the Leased Real Property or (2) existing, pending or threatened zoning, building code or other moratorium proceedings, or similar matters that would reasonably be expected to adversely affect the Acquired Companies’ ability to operate the Leased Real Property after the Closing Date as it is currently operated.

(e)    Condition of Leased Real Property. The buildings, improvements and fixtures located on the Leased Real Property and leased by an Acquired Company under Real Property Leases are adequate and suitable for the purposes for which they are presently being used by such Acquired Company. With respect to Leased Real Property (i) leased under a lease which is not an Existing

Related Party Lease, to the Knowledge of the Partners, and (ii) leased under an Existing Related Party Lease, there are no condemnation, expropriation, eminent domain or similar proceedings pending (or, with respect to all Leased Real Property, to the Knowledge of the Partners, threatened or contemplated) that affect any of the Leased Real Property, any part thereof or any improvements thereon. None of Acquired Companies or the Partners have received any notice, written or oral, of the intention of any Governmental Entity or other Person to take by condemnation, expropriation or eminent domain all or any part of any of the Leased Real Property. Neither the whole nor any material portion of any Leased Real Property is currently damaged or destroyed by fire or other casualty.

All Personal Property is in reasonably sufficient operating condition and repair, ordinary wear and tear excepted, to allow the business of the Acquired Companies to be operated in the ordinary course of business as currently operated.  Schedule 2.7 describes in reasonable detail each addition, sale, transfer or other disposition of any Personal Property having an estimated fair market value or book value in excess of $50,000 since the Interim Balance Sheet Date; provided that, each sale, transfer or other disposition of Personal Property since the Interim Balance Sheet Date with a fair market value or book value, as applicable, of $50,000 or less does not exceed, in the aggregate, $500,000.

Section 2.16    Company Benefit Plans.

(a)    Definitions. The term “Company Benefit Plan” means each Employee Benefit Plan that is sponsored, maintained or contributed to by any Acquired Company or any of its ERISA Affiliates, or with respect to which any Acquired Company or any of its ERISA Affiliates has any direct or indirect obligation to make contributions or payments or with respect to which any Acquired Company or any of its ERISA Affiliates has, or within the last six (6) years had, or could incur, any liability. Schedule 2.16 identifies each Company Benefit Plan. Each Company Benefit Plan identified on Schedule 2.16 that is or was a Multiemployer Plan is referred to herein as a “Company Multiemployer Plan” and each other Company Benefit Plan identified on Schedule 2.16 is referred to herein as a “Company Other Plan.” The term “Employee Benefit Plan” means each (i) “employee benefit plan,” as such term is defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) plan that would be an employee benefit plan described in clause (i) of this sentence if it were subject to ERISA, such as foreign plans and plans for directors, (iii) equity bonus, equity ownership, equity option, restricted equity, equity purchase, equity appreciation rights, phantom equity, or other equity-based compensation plan or arrangement, (iv) profit participation, bonus or incentive award plan or arrangement, deferred compensation agreement or arrangement (including any salary deferrals), executive compensation or supplemental income arrangement, personnel policy, vacation or paid time off policy, severance pay plan, policy or agreement, consulting agreement, or employment agreement, including Existing Employment Agreements, and (v) other employee benefit plan, agreement, arrangement, program, practice or understanding providing for employee benefits or for the remuneration, direct or indirect, of employees, former employees, managers, directors, officers, consultants, independent contractors, contingent workers or leased employees or the dependents of any of them (whether written or oral). The term “ERISA Affiliate” means, with respect to any entity, trade or business, any other entity, trade or business that is treated pursuant to Section 414(b), (c), (m) or (o) of the Code or Section 4001(b)(l) of ERISA as a single employer with the first entity, trade or business, or that is a member of the same “controlled group” as the first entity, trade or business pursuant to Section 4001(a)(14) of ERISA, without regard to whether or not each such entity, trade or business is subject to the Code or ERISA.

(b)    Plans and Material Documents. The Partners have delivered or otherwise made available to the Purchasers or Quanta true, correct and complete copies of each of the Company Other Plans, and related trusts, if applicable, including, with respect to each, all amendments thereto. The Partners have also delivered or otherwise made available to the Purchasers or Quanta, with respect to each Company Other Plan and to the extent applicable: (i) the three (3) most recent annual or other reports filed with each Governmental Entity with respect to each such plan, including all applicable schedules and audited financial statements attached thereto, (ii) each insurance contract and other funding agreement, and all amendments thereto, (iii) the most recent summary plan description and any summaries of material modifications thereto, as well as the most recent notices to participants and beneficiaries required by Applicable Laws, (iv) the most recent audited financial statements or accounts and actuarial report or valuation required to be prepared under Applicable Laws, (v) the most recent determination letter or opinion letter issued by the U.S. Internal Revenue Service (the “IRS”), (vi) a written description of any Company Other Plan that is not set forth in writing, and (vii) all other documents that are material to the Company Other Plan.

No Acquired Company nor any of its ERISA Affiliates sponsor, maintain, contribute to or have any obligation to contribute to, or within the last six (6) years sponsored, maintained, contributed to or had any obligation to contribute to, and no Company Benefit Plan is, (i) a plan subject to Title IV of ERISA, Section 302 of ERISA or Section 412 of the Code or (ii) a Company Multiemployer Plan. No Acquired Company nor any of its ERISA Affiliates are a party to any split dollar life insurance policy or arrangement.

(d)    Performance of Obligations; Absence of Liabilities. Each Acquired Company and each of its ERISA Affiliates have timely performed in all material respects all obligations, whether arising by operation of any Applicable Laws or by contract, required to be performed by each of them in connection with the Company Benefit Plans, and there have been no defaults or violations by any other party to the Company Other Plans. All contributions required to be made by any Acquired Company and any of its ERISA Affiliates to the Company Benefit Plans pursuant to their terms and provisions or pursuant to Applicable Laws have been made timely. No Acquired Company nor any of its ERISA Affiliates have incurred, and no facts exist that could reasonably be expected to result in, any liability (direct or indirect by virtue of indemnification or otherwise) with respect to any Company Benefit Plan, including any liability, Tax, penalty or fee under ERISA, the Code or any Applicable Laws (other than to pay premiums, contributions or benefits in the ordinary course). There has been no prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code) with respect to any Company Benefit Plan, which is not otherwise exempt under Section 408 of ERISA, and that would reasonably be expected to subject any Acquired Company to any liability.

(iii)    Without limiting the generality of the foregoing restrictions, each Partner hereby further agrees that, during the Noncompete Period, such Partner shall not, and shall not permit any of such Partner’s Affiliates to, directly or indirectly, alone or as a partner, joint venturer, officer, director, shareholder, employee, consultant, agent or independent contractor of, or lender to, any Person, (x) create or maintain any business relationship with any customer of any Acquired Company with respect to any Company Activities to or for any customer, or otherwise solicit any customer of any Acquired Company for the benefit of any Competing Business, (y) request, advise or induce any customer of any Acquired Company to withdraw, curtail or cancel, or engage in any other activity that could adversely affect, the relationship such Person has with Quanta, the Purchasers, the Acquired Companies or any of their Affiliates or (z) take any action that is designed or intended to have the effect of discouraging any lessor, licensor, customer, supplier, or other business associate of any Acquired Company from maintaining business relationships that are at least as favorable with Quanta, the Purchasers, the Acquired Companies and their Affiliates after the Closing as such Person maintained with the Acquired Companies prior to the Closing Date;

provided, however, that the passive ownership of no more than one percent (1.0%) of the ownership interests of an entity having a class of securities that is traded on a national securities exchange or over-the-counter market (not including any securities received pursuant to this Agreement) shall not be a violation of this ‎Section 4.4(d). Each Partner acknowledges that the covenants contained herein are in addition to those set forth in any employment agreement or other compensation-related arrangement between such Partner, on the one hand, and Quanta, the Purchasers, an Acquired Company or any of their Affiliates, on the other, and nothing herein is intended to or shall limit the covenants contained therein or vice versa.

If a judicial determination is made by a court of competent jurisdiction that any of the provisions of this ‎Section 4.4 constitutes an unreasonable or otherwise unenforceable restriction against any of the Partners, the provisions of this ‎Section 4.4 shall be rendered void only to the extent that such judicial determination finds such provisions to be unreasonable or otherwise unenforceable with respect to such Partner. In this regard, the Parties hereby agree that any court of competent jurisdiction construing this Agreement shall be empowered to sever any portion of the Territory, any prohibited business activity or any time period from the coverage of this ‎Section 4.4 and to apply the provisions of this ‎Section 4.4 to the remaining portion of the Territory, the remaining business activities and the remaining time period not so severed by such court of competent jurisdiction.

If any court of competent jurisdiction determines that any provision of this ‎Section 4.4 is unenforceable as to the Partners because of the duration or geographic scope of such provision, such court shall have the power to reduce the duration or scope of such provision, as the case may be, as to the Partners and, in its reduced form, such provision shall then be enforceable.

The Partners hereby acknowledge and agree that the remedies at law may be inadequate to protect the Acquired Companies and the Purchasers against any actual or threatened breach of the provisions contained in this ‎Section 4.4 by any Partner, and that any such breach may cause irreparable harm, and, as such, each of the Partners further agrees that the Purchasers may be entitled to injunctive relief without making proof of actual damages. Such injunctive relief shall not be deemed exclusive remedies for any such breach, but shall be in addition to and without prejudice to any other rights or remedies otherwise available to the Purchasers. Each of the Partners agrees that, in connection with any injunctive relief sought by the Purchasers, any and all requirements for proof of actual damages or bonding are hereby waived. In the event of any legal proceeding (whether at law or in equity) relating to this Agreement, if a court of competent jurisdiction determines that a Party has breached this Agreement, then that Party shall be liable and pay to the other Party any out-of-pocket costs incurred by such other Party in connection with such proceeding and any appeal therefrom, including reasonable fees of outside legal counsel, and the other Party shall be entitled to pursue the recovery of all damages, losses and liabilities related to such breach.

(h)    Reasonable Restraint. It is agreed by the Parties hereto that the foregoing covenants in this ‎Section 4.4 are necessary in terms of time, activity and territory to protect the interests of the Purchasers in the assets and businesses being acquired pursuant to the terms of this Agreement and impose a reasonable restraint on the Partners in light of the activities and businesses of the Acquired Companies on the Closing Date and the current plans of the Acquired Companies.

Section 4.5    Tax Matters.

(a)    Tax Periods Ending on or Before the Closing Date. The Partners will prepare or cause to be prepared, and timely file or cause to be timely filed, at the Partners’ sole expense, all Tax Returns of each Acquired Company or with respect to the assets of each Acquired Company for any taxation period ending on or before the Closing Date including but not limited to such Tax Returns that are due after the Closing Date (taking into account extensions). Such Tax Returns will be prepared by treating items on such Tax Returns in a manner consistent with the past practice with respect to such items unless otherwise required by Applicable Law. The Partners Representative will provide to Quanta a draft of each such Tax Return (along with supporting workpapers) at least thirty (30) days prior to the due date for the filing and, in the case of a Tax Return due within thirty (30) days after the Closing Date, as soon as practical before the filing date. Within fifteen (15) days after receipt of the draft of each such Tax Return, or as soon as practical after the receipt of a Tax Return due within thirty (30) days after the Closing, Quanta will notify the Partners Representative of the existence of any objection, specifying in reasonable detail the nature and basis of such objection, to any items set forth on such draft Tax Return. Quanta and the Partners Representative agree to consult and resolve in good faith any such objection, it being agreed that if an item is being treated in a manner consistent with past practice, such item will be rebuttably presumed to be reasonable and appropriate. The Partners shall timely pay to the appropriate Tax Authority an amount that is equal to the excess, if any, of (x) the aggregate Taxes payable by the Acquired Companies as shown on the Tax Returns over (y) the amount of any estimated payments previously made prior to the Closing Date with respect to the taxable period for which such Taxes relate (such excess amount, the “Pre-Closing Tax Excess Amount”); provided, that no amount shall be included in the computation of the Pre-Closing Tax Excess Amount to the extent that such amount has been included as an asset or liability in the computation of Closing Date NWC. No payment pursuant to this ‎Section 4.5(a) shall excuse the Partners from their indemnification obligations pursuant to Section 8.1 if the amount of Taxes as ultimately determined (on audit or otherwise) for the periods covered by such Tax Returns exceeds the amount taken into account in the Pre-Closing Tax Excess Amount. Promptly after the filing of the Tax Returns, the Partners Representative shall provide to Quanta a copy of such Tax Returns as executed and filed and evidence of any Tax payments made in connection with such Tax Returns.

(b)    Tax Periods Beginning on or Before and Ending After the Closing Date. The Purchasers shall prepare or cause to be prepared, and timely file or cause to be timely filed, all Tax Returns of each Acquired Company or with respect to the assets of each Acquired Company for all taxation periods which begin on or before the Closing Date and end after the Closing Date (a “Straddle Period”). Such Tax Returns will be prepared by treating items on such Tax Returns in a manner consistent with the past practice with respect to such items unless otherwise required by Applicable Law. Quanta will provide to the Partners Representative a draft of each such Tax Return (along with supporting workpapers) at least thirty (30) days prior to the due date for its filing and, in the case of

a Tax Return due within thirty (30) days after the Closing Date, as soon as practical before the filing date. Within fifteen (15) days after receipt of the draft of each such Tax Return, or as soon as practical after the receipt of a Tax Return due within thirty (30) days after the Closing, the Partners Representative will notify Quanta of the existence of any objection specifying in reasonable detail the nature and basis of such objection to any items set forth on such draft Tax Return. Quanta and the Partners Representative agree to consult and resolve in good faith any such objection, it being agreed that if an item is being treated in a manner consistent with past practice, such item will be rebuttably presumed to be reasonable and appropriate. The Partners shall pay to Quanta no later than five (5) days prior to the due date for the payment of Taxes with respect to such periods an amount equal to the excess, if any, of (x) the portion of such Taxes that relates to the portion of such taxable period ending on the Closing Date over (y) the sum of the amount of any estimated payments previously made prior to the Closing Date with respect to the taxable period for which such Taxes relate (such excess amount, the “Straddle Period Tax Excess Amount”); provided, that no amount shall be included in the computation of the Straddle Period Tax Excess Amount to the extent that such amount has been included as an asset or liability in the computation of Closing Date NWC. No payment pursuant to this ‎Section 4.5(b) shall excuse the Partners from their indemnification obligations pursuant to Section 8.1 if the amount of Taxes as ultimately determined (on audit or otherwise) for the periods covered by such Tax Returns exceeds the amount taken into account in the Straddle Period Tax Excess Amount.

(c)    For purposes of determining the amount of any Taxes due for a Straddle Period, the amount of any Tax that is attributable to the portion of a taxable period ending on the Closing Date shall be:

(i)    in the case of Taxes that are either (A) based upon or related to income or receipts, or (B) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible), deemed equal to the amount that would be payable if the Tax period of the Acquired Companies ended with (and included) the Closing Date; provided that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the period ending on and including the Closing Date and the period beginning after the Closing Date in proportion to the number of days in each period; and

(ii)    in the case of Taxes that are imposed on a periodic basis with respect to the assets or capital of the Acquired Companies, 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 portion of the period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire period.

(d)    Cooperation on Tax Matters. The Parties shall cooperate fully, as and to the extent reasonably requested by each other Party, in connection with the preparation and filing of Tax Returns pursuant to this ‎Section 4.5 and any audit, litigation or other proceeding with respect to Taxes.

Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Parties agree (i) to the extent not delivered to the other Party or its Affiliates pursuant to this Agreement, to retain all books and records in their possession or control with respect to Tax matters pertinent to each Acquired Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by the Parties, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Tax Authority, and (ii) if any other Party so requests, each Party shall allow any other Party to take possession of such books and records. The Parties further agree, upon request, to use their best efforts to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any Taxes that could be imposed on any Acquired Company or otherwise related to the transactions contemplated in this Agreement.

(e)    Other Taxes. All transfer, documentary, sales, use, stamp, registration and other similar Taxes and fees (including penalties and interest) incurred in connection with this Agreement shall be paid one-half by the Purchasers and one-half by the Partners when due, and the party required by Applicable Law shall timely file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, registration and other Taxes and fees, and, if required by Applicable Law, the other parties shall, and shall cause their affiliates to, join in the execution of any such Tax Returns and other documentation. The expense of such filings shall be paid one-half by the Purchasers and one-half by the Partners.

(f)    Tax Refunds. Any refunds of Tax (including interest paid thereon) that are received by the Purchasers, Quanta or any of their respective Affiliates (including the Acquired Companies), and any amounts credited against Tax to which the Purchasers, Quanta or any of their respective Affiliates (including the Acquired Companies) become entitled, after the Closing Date that relate to taxable periods of the Acquired Companies that end on or prior to the Closing Date shall be for the account of the Partners, except to the extent such refund is included in the computation of Closing Date NWC.

The Losses of the Purchaser Indemnified Parties described in this ‎Section 8.1 as to which the Purchaser Indemnified Parties are entitled to indemnification are hereinafter collectively referred to as the “Purchaser Losses.” For purposes of clarification and notwithstanding anything to the contrary contained herein, “severally and not jointly” in this Section 8.1 means that each Partner is liable only for its proportionate share of the Purchaser Losses (subject to the limitations contained herein), calculated based on such Partner’s Pro Rata Share, and no Partner shall be liable for aggregate Purchaser Losses in excess of such Partner’s Pro Rata Share thereof; provided, however, that the indemnification obligations of each Partner with respect to any Purchaser Losses arising under (x)

The Losses of the Partner Indemnified Parties described in this ‎Section 8.2 as to which the Partner Indemnified Parties are entitled to indemnification are hereinafter collectively referred to as “Partner Losses.”

Section 8.3    Indemnification Procedure.

(a)    Promptly, but in any event within thirty (30) days after receipt by a Purchaser Indemnified Party or a Partner Indemnified Party (hereinafter referred to, as applicable, as an “Indemnified Party”) of notice by a third party (including any Governmental Entity) of any Action with respect to which such Indemnified Party may be entitled to receive payment hereunder for any Purchaser Losses or any Partner Losses (as the case may be), such Indemnified Party will notify the Partners, on the one hand, or the Purchasers and Quanta, on the other hand, as the case may be (in such capacity, the Partners or the Purchasers and Quanta, as applicable, are hereinafter referred to as an “Indemnifying Party”), in writing, of any such Action, which notice shall specify in reasonable detail the basis for such claim and the nature of the Loss; provided, however, that (x) the failure to so notify the Indemnifying Party will relieve the Indemnifying Party from liability under this Agreement with respect to such Action only if, and only to the extent that, such failure to notify the Indemnifying Party results in the forfeiture by the Indemnifying Party of material rights and defenses otherwise available to the Indemnifying Party with respect to such Action and (y) no such notice shall be required with respect to any of the matters set forth on Schedule 2.11. Unless (i) the Indemnified Party shall have received advice from its selected counsel that a conflict of interests exists that would make joint representation inappropriate, (ii) if the Partners are the Indemnifying Party, such Action seeks an injunction or other equitable relief against any Indemnified Party, (iii) upon written request of the Indemnified Party at any time, the Indemnifying Party fails to provide reasonable assurance to the Indemnified Party of its financial capacity to defend and provide indemnification with respect to such Action or (iv) the Action involves any of the matters covered by ‎Section 8.1(e), the Indemnifying Party will have the right, at its sole expense, to assume the defense of such Action, upon written notice delivered to the Indemnified Party within ten (10) days after receiving such notice and, with respect to each Action for which it has assumed the defense under this ‎Section 8.3(a), to maintain the defense of such Action, in each case, with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party; provided that the Indemnifying Party shall have acknowledged in writing to the Indemnified Party its unqualified obligation to fully indemnify the Indemnified Party pursuant to this ‎Article VIII with respect to each Action for which the Indemnifying Party has assumed the defense under this ‎Section 8.3(a), and the Indemnifying Party agrees to its unqualified obligation to fully indemnify the Indemnified Party pursuant to ‎Article VIII with respect to each Action for which the Indemnifying Party maintains the defense. In the event, however, that (A) the Indemnifying Party declines or fails to (1) assume or maintain the defense of the Action, (2) provide reasonable assurance to the Indemnified Party of its financial capacity to defend and provide indemnification with respect to such Action or (3) employ counsel reasonably satisfactory to the Indemnified Party, in any case, on the terms provided above, or (B) the Indemnified Party shall have received advice from its selected counsel that a conflict of interests exists that would make joint representation inappropriate, then such Indemnified Party may employ counsel to represent or defend it in any such Action, and the Indemnified Party’s reasonable fees and disbursements of such counsel shall be considered Losses for purposes of this Article VIII; 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. The Indemnifying Party shall use its reasonable best efforts to maintain the defense of each Action for which it has assumed the defense under this ‎Section 8.3(a)

and of each Action related to the matters covered by ‎Section 8.1(e). In any Action with respect to which indemnification is being sought hereunder, the Indemnified Party or the Indemnifying Party, whichever is not assuming or maintaining the defense of such Action, will have the right to participate in such matter and to retain its own counsel at such Person’s own expense, so long as, in the event the Indemnifying Party fails to assume or maintain the defense of any such Action, the Indemnifying Party acknowledges in writing to the Indemnified Party that it is, without qualification, obligated to fully indemnify the Indemnified Party pursuant to this Article VIII with respect to such Action pays the amounts required hereunder, including the reasonable fees and disbursements of the Indemnified Party’s counsel as incurred; provided that, for the avoidance of doubt, the fees and expenses incurred by the Indemnified Party prior to the assumption of any Action by the Indemnifying Party shall be considered Losses for purposes of this Article VIII, and such fees and expenses shall be borne by the Indemnified Party only to the extent that the Indemnifying Party has already properly assumed and maintained such defense; 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. The Indemnifying Party or the Indemnified Party, as the case may be, will at all times use reasonable efforts to keep the Indemnified Party or the Indemnifying Party, as the case may be, reasonably and promptly apprised of the status of the defense of any Action the defense of which they are maintaining and to cooperate in good faith with each other with respect to the defense of any such Action; provided, however, that, in the event the Indemnifying Party fails to assume or maintain the defense of any such Action, the Indemnified Party will have no such obligations unless the Indemnifying Party acknowledges in writing to the Indemnified Party that it is, without qualification, obligated to fully indemnify the Indemnified Party pursuant to this Article VIII with respect to such Action pays the amounts required hereunder, including the reasonable fees and disbursements of the Indemnified Party’s counsel as incurred. Notwithstanding anything to the contrary in this Agreement, the Purchasers shall assume and control the defense of any Action with respect to Taxes involving a Straddle Period; provided, however, that the Purchasers may not settle or compromise any claim or consent to the entry of any judgment with respect to such Action that would give rise to an indemnification obligation under ‎Section 8.1 without the prior written consent of the Partners, which consent shall not be unreasonably withheld, conditioned or delayed.

(b)    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 without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed), unless: (i) the Indemnifying Party does not assume or fails to maintain the defense of such claim pursuant to ‎Section 8.3(a) or (ii) such settlement, compromise or consent (A) includes an unconditional release of each Indemnifying Party from all liability arising out of such claim, (B) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of any Indemnifying Party, (C) does not contain any equitable order, judgment or term which in any manner adversely affects, restrains or interferes with the business of any Indemnifying Party or any Indemnifying Party’s Affiliates and (D) does not and will not result in any increase in Taxes of any Indemnifying Party or any Indemnifying Party’s Affiliate, or adverse effect on Taxes of any Indemnifying Party or any Indemnifying Party’s Affiliate, for any taxable period or portion thereof ending on or prior to the Closing Date. An Indemnifying Party may not, without the prior written

consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder unless such settlement, compromise or consent (1) includes an unconditional release of each Indemnified Party from all liability arising out of such claim, (2) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of any Indemnified Party, (3) does not contain any equitable order, judgment or term which in any manner adversely affects, restrains or interferes with the business of any Indemnified Party or any Indemnified Party’s Affiliates and (4) does not and will not result in any increase in Taxes of any Indemnified Party or any Indemnified Party’s Affiliate, or adverse effect on Taxes of any Indemnified Party or any Indemnified Party’s Affiliate, for any taxable period or portion thereof after the Closing Date.

(c)    A claim for indemnification by an Indemnified Party for any matter not involving an Action by a third party shall be asserted by written notice to the Indemnifying Party from whom indemnification is sought. Such notice will specify in reasonable detail the basis for such claim and the nature of the Loss. As promptly as possible after the Indemnified Party has given such notice, such Indemnified Party and the appropriate Indemnifying Party will establish the merits and amount of such claim (by mutual agreement, litigation, arbitration or otherwise) and, within five (5) Business Days of the final determination of the merits and amount of such claim, the Indemnifying Party will pay to the Indemnified Party immediately available funds in an amount equal to such claim as determined hereunder.

(A)    any Purchaser Loss arising out of or relating to any breach of any of the Fundamental Representations, the Special Representations, the representations and warranties made in ‎Section 2.9(b) (Known Long-Term Liabilities) and ‎Section 2.24(a) (Accounts Receivable) shall not be subject to the Customer Claims Caps;

(C)    for the avoidance of doubt, notwithstanding that any Purchaser Loss referred to in the preceding clauses (A) or (B) may also arise out of or relate to Customer-Related Claims, no such Purchaser Loss referred to in the preceding clauses (A) or (B) shall be included in calculating whether or not any Customer Claims Cap has been reached or exceeded; and

(D)    the aggregate amount of all Purchaser Losses for which a Partner shall be liable pursuant to ‎Section 8.1(d) in connection with (x) Second Set Claims shall give effect to any Purchaser Losses arising in connection with First Set Claims such that for purposes of calculating the 17.5% Claims Cap described in clause (y) above, Purchaser Losses arising in connection with the First Set Claims shall be applied towards such 17.5% Claims Cap and (y) Third Set Claims shall give effect to any Purchaser Losses arising in connection with First Set Claims and Second Set Claims such that for purposes of calculating the 10% Claims Cap described in clause (z) above, Purchaser Losses arising in connection with First Set Claims and Second Set Claims shall be applied towards such 10% Claims Cap.

(iii)    Subject to the other limitations contained in this Agreement, (A) except for Purchaser Losses arising under ‎Section 8.1(c), the aggregate indemnification obligations of a Partner under ‎Section 8.1 shall be limited to an amount equal to one-hundred percent (100%) of such Partner’s Pro Rata Share of the Purchase Price and (B) except for Partner Losses arising under ‎Section 8.2(c), the aggregate indemnification obligations of the Purchasers and Quanta under ‎Section 8.2 shall be limited to an amount equal to the Purchase Price.

(c)    Determination of Losses. For purposes of determining Purchaser Losses pursuant to this ‎Article VIII and for purposes of determining whether there has been a breach or alleged breach of any representation or warranty by any Partner, all qualifications in such representation or warranty referencing the terms “material,” “materiality,” “material adverse effect,” “Material Adverse Effect,” or other terms of similar import or effect shall be disregarded; provided, however, that this Section 8.5(c) shall not apply to the representations and warranties contained in the final sentence of Section 2.10(a), Section 2.11, Section 2.13(p) and the first sentence of Section 2.20(b).

(d)    Insurance Recovery. The amount of any Purchaser Losses shall be calculated net of any amounts that Quanta or any of its subsidiaries (including the Acquired Companies) receive under insurance policies with respect thereto (in each case net of any costs or expenses incurred by the Purchaser Indemnified Parties in connection with securing or obtaining such proceeds, including any deductibles, co-payments, self-insurance or retention amounts, any retroactive or retrospective premium adjustments, and the reasonable estimate, by Quanta, of the amount of any future premium adjustments or other chargebacks solely with respect to the period ending five (5) full policy years after the date of payout of insurance proceeds with respect to the event or occurrence giving rise to such Purchaser Loss), in each case only to the extent arising out of or related thereto). The Purchasers agree to use commercially reasonable efforts to seek insurance recovery with respect to any such claim for such Losses under such insurance policies; provided, however, that “commercially reasonable efforts” for purposes of this Section 8.5(d) shall not include the commencement or threat of litigation or the expenditure of third party expenses; provided, further, that such obligation (and the availability of such insurance policies or the timing of any such recovery thereunder) shall not affect the Purchaser Indemnified Parties’ ability to exercise the remedies available to them under this Article VIII. In the event that an insurance recovery is made by a Purchaser Indemnified Party with respect to any ‎Loss for which any such Purchaser Indemnified Party has been indemnified hereunder, then a refund ‎equal to the aggregate amount of the insurance recovery (up to the amount paid to such Purchaser ‎Indemnified Party pursuant to the provisions of Article VIII hereof) shall be made promptly to the ‎Indemnifying Party (in each case net of any costs or expenses incurred by such Purchaser Indemnified ‎Party in connection with securing or obtaining such proceeds as set forth in the first sentence of this ‎Section 8.5(d)).‎

(e)    Closing Date NWC. Notwithstanding anything to the contrary set forth in this Article VIII, no Partner shall have any obligation to indemnify any Purchaser Indemnified Party pursuant to this Article VIII for any Purchaser Loss to the extent that such amount is specifically included as a liability in the calculation of the Closing Date NWC as finally determined under ‎Section

1.5(d), and the amount thereof shall not be applied against the Deductible.

(f)    In no event shall any Indemnifying Party be liable to any Indemnified Party under this Article VIII or otherwise for any punitive damages or any indirect, special or consequential damages that are speculative or remote (except to the extent such damages are reasonably foreseeable) relating to the breach or alleged breach of this Agreement, except, in each case, to the extent any such damages are paid in respect of a third party claim.

Section 8.6    Investigations. The investigations and inquiries made by or on behalf of the Purchasers and Quanta and the information, materials and documents supplied to the Purchasers and Quanta and/or their respective representatives in connection with their review of the Acquisition, the Acquired Companies and the businesses of the Acquired Companies shall not (and were not intended to) limit or affect the representations and warranties of any of the Partners or relieve any of them from any of their respective obligations and liabilities in respect thereof. The respective representations and warranties of the Parties contained in this Agreement or in any certificate or other document delivered by any Party prior to the Closing and the rights to indemnification set forth in this ‎Article VIII will not be deemed waived or otherwise affected by any investigation made by a Party to this Agreement.

Section 8.7    Purchase Price Adjustments; Taxation of Escrow Amount. Any payment of a claim of indemnification pursuant to this Article VIII shall be deemed to be an adjustment to the Purchase Price. For all relevant Tax purposes, and to the extent permitted by Applicable Laws, the Parties will treat the Escrow Fund as an asset of the Purchasers until the release thereof to the Partners or the Purchasers, as applicable, and the Purchasers shall pay all Taxes on any interest or other income earned with respect to the Escrow Fund until it is released to the Partners or the Purchasers, as applicable.

Section 8.8    Escrow.

(a)    Other than with respect to any Unpaid Amounts, any indemnification to which a Purchaser Indemnified Party is entitled under this Agreement shall first be made as a payment to the Purchaser Indemnified Party from the Escrow Fund in accordance with the terms of the Escrow Agreement.

(b)    All claims for indemnification asserted by a Purchaser Indemnified Party under ‎Section 8.1 during the period commencing on the Closing Date and ending on the date that is two (2) years after the Closing Date (the “Escrow Period”) that are not resolved and satisfied (including the obligation to pay any such indemnity claim) shall be deemed to be “Pending Claims.” The dollar amount of all Losses claimed in good faith in respect of Pending Claims is hereinafter referred to as the “Pending Claim Amount.”

(c)    If, on the first Business Day following the last day of the Escrow Period (the “Release Date”), the amount remaining in the Escrow Fund (the “Escrow Account Balance”) exceeds the Pending Claim Amount, if any, the Escrow Agent shall release and deliver to the Partners Representative (on behalf of the Partners), in accordance with the Escrow Agreement, the amount of such excess, as set forth below and in the Escrow Agreement. If, on the Release Date, the Pending

Claim Amount, if any, exceeds or is equal to the Escrow Account Balance, the Escrow Account Balance will continue to be held by the Escrow Agent pursuant to the terms of the Escrow Agreement until such Pending Claims have been fully resolved, and the Escrow Agreement shall be deemed to be extended accordingly.

(d)    Notwithstanding any amount of the Escrow Account Balance being released and delivered to the Partners Representative pursuant to ‎Section 8.8(c), the Partners acknowledge that the Purchasers’ right to the Escrow Fund pursuant to ‎Section 8.8(a) is a non-exclusive remedy, and the Partners shall remain liable for any Purchaser Losses pursuant to ‎Section 8.1 to the extent provided, and subject to the limitations set forth, in this ‎Article VIII.

Section 8.9    Exclusive Remedy. Except with respect to (i) the Partners’ obligations under ‎Section 4.4 and ‎Section 8.1(c), (ii) any obligations in respect of any Employment Agreement or Related-Party Lease Agreement, (iii) specific performance and equitable remedies, and (iv) remedies that cannot be waived under Applicable Laws, the foregoing indemnification provisions in this ‎Article VIII and the offset rights of Purchaser under ‎Section 11.6 shall be the sole and exclusive remedies of the Purchaser Indemnified Parties and the Partner Indemnified Parties for any Losses and any and all claims arising under, out of or related to this Agreement and the transactions contemplated hereby.

(e)    Such Partner or such Partner’s representative has had an adequate opportunity to ask questions and receive answers from the officers of the Purchasers and Quanta concerning, among other matters, the Purchaser, Quanta, their respective management, their plans for the operation of their businesses and potential additional acquisitions;

(g)    Such Partner acknowledges that the Restricted Shares being acquired by such Partner were not offered to such him or it by means of publicly disseminated advertisements or sales literature, nor is such Partner aware of any offers made to any other Partner by such means.

Without limiting the generality of the foregoing, after the applicable Lock-up Period, such Restricted Shares may be offered, sold, assigned, pledged, hypothecated, transferred or otherwise disposed of, directly or indirectly, only after full compliance with all of the applicable provisions of the Securities Laws. Certificates representing the Restricted Shares shall bear the following legend, which shall reflect the Lock-up Periods, in addition to the legend under Section 9.1:

Section 11.3    Assignment; Successors in Interest. No assignment or transfer by any Party of its rights and obligations under this Agreement will be made except with the prior written consent of the other Parties to this Agreement; provided, that each Purchaser shall, without the obligation to obtain the prior written consent of the Partners, be entitled to assign this Agreement or all or any part of its rights or obligations hereunder to any one or more Affiliates of such Purchaser and, provided, further, that, without obtaining the prior written consent of the Partners, Quanta and each Purchaser (or any such Affiliate, if applicable) may pledge, assign and grant to Quanta’s and such Purchaser’s (or such Affiliate’s) lenders, for the benefit of such lenders, a continuing security interest and lien on all of Quanta’s, such Purchaser’s or such Affiliate’s right, title and interest in and to this Agreement and any and all related agreements, as security for the payment and performance of all obligations of Quanta, such Purchaser or such Affiliate to such lenders by reason of borrowing or the guarantee of borrowing, or otherwise; provided, however, that no assignment permitted by this Section 11.3 will relieve Quanta or the Purchasers of their respective obligations under this Agreement and in any event, the Purchasers and Quanta, as applicable, shall promptly provide the Partners with written notice of any such assignment. Notwithstanding the foregoing, Quanta may assign its rights and obligations under this Agreement to any Person without obtaining the prior written consent of the Partners in connection with any merger, sale of substantially all of Quanta’s assets or other business combination, however structured, involving Quanta, including a Change in Control; provided, however, that the Purchasers and Quanta, as applicable, shall promptly provide the Partners with written notice of any such assignment. This Agreement will be binding upon and will inure to the benefit of the Parties and their successors and permitted assigns, and any reference to a Party will also be a reference to a successor or permitted assign.

The Partners shall have the right to withhold and offset against any amount otherwise due to be paid to the Purchasers or Quanta pursuant to this ‎Agreement any amounts to be paid to the Partners (or any Partner Indemnified Party) by the Purchasers or Quanta (including any amount related to any amounts due to the Partners pursuant to ‎Section 4.9(a)).

Section 11.7    Guarantee.

(a)    Joseph Michael Durham (the “Guarantor”) hereby irrevocably, unconditionally and absolutely guarantees as a primary obligor and not as a surety, to each of the Purchasers and Quanta, the full and timely payment and due and punctual performance and discharge of the obligations of TECAN LP, a Delaware limited partnership (“Tecan”), under this Agreement as if the Guarantor was individually responsible for such covenants and obligations (collectively, the “Obligations”). The guarantee under this ‎Section 11.7 is an irrevocable, unconditional and absolute guaranty of timely payment and performance of the Obligations and not merely of collection. If for any reason whatsoever the Obligations shall not be fully and timely paid or performed in accordance with this Agreement, the Guarantor shall promptly honor and perform any Obligations to the Purchasers or Quanta, as applicable, hereunder upon demand.

(b)    To the fullest extent permitted by Applicable Law, the obligations of the Guarantor hereunder shall remain in full force and effect without regard to, and shall not be affected or impaired by, (i) any amendment or modification of the terms of this Agreement; (ii) any dealings or transactions between any of the Purchasers, Quanta or the Partners or any of their respective Affiliates relating to this Agreement, whether or not the Guarantor shall be a party to or cognizant of the same, unless the Purchasers or Quanta shall have waived compliance by Tecan with respect to any such obligations in accordance with the terms of this Agreement; (iii) the failure to give notice to Guarantor of any breach of this Agreement; (iv) the existence of any claim, set-off or other right which the Guarantor may have against any Partner or any other Person, whether in connection with the transactions contemplated by this Agreement or any unrelated transactions; (v) any change in the entity existence (including changes to the certificate of limited partnership, partnership agreement, laws, rules, regulations or powers or any merger, consolidation, liquidation, winding-up or dissolution), structure or ownership of Tecan, or any insolvency, bankruptcy, reorganization or other similar proceeding or transaction affecting Tecan or its assets; or (vi) any incapacity or lack of or limitation on the status, power, authority or legal personality of Tecan or its general partner or agents thereof. The Guarantor shall be entitled to all rights of set-off, counterclaim, deduction and defense that Tecan currently has or hereafter may have pursuant to this Agreement, including any amendment in accordance with the terms of this Agreement, other than those relating to or arising out of any incapacity, bankruptcy, insolvency, liquidation, reorganization or other similar event or condition with respect to Tecan or as otherwise provided in this ‎Section 11.7(b).

(c)    In connection with this ‎Section 11.7, the Guarantor unconditionally waives: (i) any right to receive demands, protests, or other notices of any kind or character whatsoever, as the same may pertain any Partner; (ii) any right to require the Purchasers or Quanta, as applicable, to proceed first against any Partner or to pursue any other remedy; (iii) any defense based upon an

election of remedies by any Partner; (iv) any duty of any Partner to advise the Guarantor of any information known to any of the Purchasers or Quanta regarding Tecan or its ability to perform under this Agreement; (v) all suretyship and other defenses of every kind and nature; (vi) all rights to and benefits under any defense based on or arising out of the voluntary or involuntary bankruptcy, insolvency, liquidation, dissolution, receivership, or other similar proceeding affecting any Partner; (vii) requirements of promptness or diligence on the part of any of the Purchasers or Quanta that are not required by this Agreement; (viii) notice of acceptance hereof, of any action taken or omitted in reliance hereon, of any defaults by Tecan in the payment or performance of the Obligations; and (ix) all notices which may be required by Applicable Law or otherwise to preserve any of the rights of the Purchasers or Quanta against the Guarantor.

(d)    The obligations of the Purchasers and Quanta hereunder shall conclusively be deemed to have been created, contracted or incurred in reliance upon the guarantee under this ‎Section 11.7, and all dealings between the Partners and the Guarantor, on the one hand, and the Purchasers and Quanta, on the other, shall likewise be conclusively presumed to have been had or consummated in reliance upon the guarantee under this ‎Section 11.7.

(e)    None of the Purchasers or Quanta shall be obligated to file any claim relating to any obligation in the event that Tecan becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Purchasers or Quanta to so file shall not affect the Obligations. In the event that any payment by Tecan to the Purchasers or Quanta in respect of any Obligation is rescinded or is otherwise returned as a result of any bankruptcy, reorganization or similar proceeding, the Guarantor shall remain liable hereunder with respect to the Obligations as if such payment had not been made.

(f)    The Guarantor shall not be entitled to be subrogated to any of the rights of any of the Purchasers or Quanta against the Guarantor or any collateral, security or guarantee or right of set-off held by any of the Purchasers or Quanta for the payment or performance of the Obligations, nor shall the Guarantor seek or be entitled to seek any reimbursement from any of the Purchasers or Quanta in respect of performance made by the Guarantor hereunder, until the Obligations are indefeasibly paid and performed in full.

(g)    The Guarantor agrees to promptly take all actions required to timely discharge the Obligations, and the Guarantor acknowledges and agrees that the Purchasers shall be entitled to specific performance against the Guarantor (without the posting of bond or other security) if required to specifically enforce the Obligations. The Guarantor agrees to indemnify and hold the Purchasers or Quanta harmless from and against and to pay all out-of-pocket costs and expenses (including reasonable fees and expenses of outside legal counsel) incurred by or on behalf of any of the Purchasers or Quanta, as applicable, in connection with the collection and/or enforcement of the Guarantor’s obligations under this ‎Section 11.7.

(h)    The Guarantor hereby represents and warrants to each of the Purchasers and Quanta each of the representations and warranties set forth in ‎Section 2.2, ‎Section 2.4 and ‎Section 2.5 with respect to himself, mutatis mutandis.

(i)    The Guarantor may not assign its rights, interests or obligations hereunder to any other Person without the prior written consent of the Purchasers and Quanta. The guarantee under this ‎Section 11.7 shall remain in full force and effect and shall be binding on the Guarantor, its successors and assigns until the Obligations are satisfied in full.

Section 11.8    Controlling Law; Amendment. This Agreement will be governed by and construed and enforced in accordance with the internal laws of the State of Delaware without reference to its choice of law rules. This Agreement may not be amended, modified, or supplemented except by written agreement executed and delivered by all of the Parties.

Section 11.9    Consent to Jurisdiction, Etc.; Waiver of Jury Trial. Except for disputes arising out of or in connection with Closing Date NWC, Adjusted EBITDA and Contingent Consideration which shall be finally resolved by the Expert in accordance with Article I, each of the Parties hereby irrevocably consents and agrees to the exclusive personal jurisdiction of the courts of the State of Texas in Harris County, Texas or the federal courts located in the Southern District of the State of Texas for any action, suit or proceeding arising in connection with any disagreement, dispute, controversy or claim arising out of or relating to this Agreement or any related document (for purposes of this Section, a “Legal Dispute”). The Parties agree that, after a Legal Dispute is before a court as specified in this ‎Section 11.9 and during the pendency of such Legal Dispute before such court, all actions, suits or proceedings with respect to such Legal Dispute or any other Legal Dispute, including any counterclaim, cross-claim or interpleader, shall be subject to the exclusive jurisdiction of such court, except that in actions seeking to enforce any order of any judgment of such court, such jurisdiction shall be non-exclusive. Each of the Parties hereby waives, and agrees not to assert, as a defense in any Legal Dispute, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in such court or that its property is exempt or immune from execution, that the action, suit or proceeding is brought in an inconvenient forum or that the venue of the action, suit or proceeding is improper. Each Party hereto agrees that a final judgment in any action, suit, or proceeding described in this Section 11.9 after the expiration of any period permitted for appeal and subject to any stay during appeal shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Applicable Laws. THE PARTIES HEREBY WAIVE IRREVOCABLY ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY IN CONNECTION WITH THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY DOCUMENT CONTEMPLATED HEREIN OR OTHERWISE RELATED HERETO.

Section 11.10    Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions of this Agreement, and any such prohibition or unenforceability in any jurisdiction will not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by Applicable Laws, the Parties waive any provision of Applicable Laws that renders any such provision prohibited or unenforceable in any respect.

Section 11.11    Counterparts. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute but

one and the same instrument. Facsimile or scanned and emailed transmission of any signed original document or retransmission of any signed facsimile or scanned and emailed transmission will be deemed the same as delivery of an original. At the request of any Party, the Parties will confirm facsimile or scanned and emailed transmission by signing a duplicate original document.

Section 11.12    No Third-Party Beneficiaries. Except as provided in ‎Article VIII, nothing expressed or implied in this Agreement is intended, or will be construed, to confer upon or give any Person other than the Parties, the Purchaser Indemnified Parties and the Partner Indemnified Parties and their respective successors and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement, or result in such Person being deemed a third party beneficiary of this Agreement.

Section 11.13    Waiver. Any agreement on the part of a Party to any extension or waiver of any provision of this Agreement will be valid only if set forth in an instrument in writing signed on behalf of such Party. A waiver by a Party of the performance of any covenant, agreement, obligation, condition, representation, or warranty will not be construed as a waiver of any other covenant, agreement, obligation, condition, representation, or warranty. A waiver by any Party of the performance of any act will not constitute a waiver of the performance of any other act or an identical act required to be performed at a later time.

Section 11.14    Entire Agreement. This Agreement (including the Schedules and Exhibits to this Agreement) and the documents executed pursuant to this Agreement supersede all negotiations, agreements and understandings among the Parties with respect to the subject matter of this Agreement (including, for the avoidance of doubt, that certain Indication of Interest, dated May 9, 2017, between Quanta, Stronghold and Stronghold Specialty and that certain Letter of Intent, dated June 8, 2017, by and among Quanta, Stronghold, Stronghold Specialty and the Partners and, upon Closing, and that certain Confidentiality and Non-Disclosure Agreement dated December 7, 2015, by and between Quanta and Stronghold) and constitute the entire agreement between the Parties.

Any reference to any law will be deemed also to refer to such law as amended, modified, succeeded or supplemented from time to time and in effect at any given time, and all rules and regulations promulgated thereunder, unless the context requires otherwise.

The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited.
