NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, covenants and agreements set forth herein, the parties hereto, intending to be legally bound hereby, agree as follows:

ARTICLE I

Section 1.1 The Merger.

(a) At the Effective Time (as hereinafter defined) and subject to and upon the terms and conditions of this Agreement, Merger Sub shall merge with and into the Company in accordance with the provisions of the ABCA, the separate corporate existence of Merger Sub shall cease and the Company shall continue as the surviving corporation (the "Surviving Corporation").

(b) The "Effective Time" shall occur upon the filing with the Arizona Corporation Commission of articles of merger (the "Articles of Merger") substantially in the form attached hereto as Exhibit A and executed in accordance with the applicable provisions of the ABCA, or at such later time as may be agreed to by Dearborn and the Company and specified in the Articles of Merger. The parties will cause the Articles of Merger to be filed with the Arizona Corporation Commission at the Closing as described in Section 1.2 below.

The date on which the Closing occurs is referred to herein as the "Closing Date".

Section 1.3 Effects of the Merger.

(a) The Merger shall have the effects provided in this Agreement, the Articles of Merger and as set forth in Title 10, Chapter 11, Article 1 of the ABCA. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

(b) At the Effective Time, the Articles of Incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the Articles of Incorporation of the Surviving Corporation until thereafter amended as provided by law and such Articles of Incorporation; provided, however, that, at the Effective Time, Article I of the Articles of Incorporation of the Surviving Corporation shall be amended to read as follows: "The name of the corporation is Xxxxxxxx & Associates, Inc.".

(c) At the Effective Time, the Bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until thereafter amended as provided by applicable law, the Articles of Incorporation of the Surviving Corporation and such Bylaws.

(d) The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, each to hold office in accordance with the Articles of Incorporation and Bylaws of the Surviving Corporation, and the officers of the Company immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, in each case until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal.

Section 1.4 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Dearborn, Merger Sub, the Company, or the holders of any of the following securities:

(a) Each share of Common Stock issued and outstanding immediately prior to the Effective Time (other than any shares of Common Stock to be canceled pursuant to Section 1.4(b)) (each, a "Share" and collectively the "Shares") shall be canceled and shall, subject to Section 1.7, be converted automatically into the right to receive the Per Share Merger Consideration (as defined below) in accordance with the provisions of this Agreement. As of the Effective Time, all such Shares shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such Shares (or, in the case of Xxxxxxx, a certificate representing the Preferred Stock which will have been converted into Common Stock pursuant to Section 6.11 and which will immediately prior to the Effective Time represent the right to receive the Common Stock issuable upon such conversion, with each to be referred to as a "Certificate") shall cease to have any rights with respect thereto, except for the right to receive, subject to Section 1.7, the Per Share Merger Consideration payable upon surrender of the Certificate (or delivery of a duly executed affidavit of lost certificate and indemnity) that formerly evidenced such Share in the manner provided in this Agreement;

(b) Each share of Common Stock held in the treasury of the Company immediately prior to the Effective Time shall be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto; and

(c) Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

Section 1.5 Exchange of Certificates.

(a) At the Effective Time, each holder of a Certificate upon surrender of the same to Dearborn (or delivery of a duly executed affidavit of lost certificate and indemnity), shall, subject to Section 1.7, be entitled to receive (the "Merger Payment") in exchange therefor the Per Share Merger Consideration in the following form:

(i) an amount equal to the Per Share Cash Merger Consideration (as defined below) multiplied by the number of shares of Common Stock of the Company represented by the Certificates; and

(ii) a certificate, registered in the name of such holder, for shares of Dearborn Common Stock (as defined below) representing the Per Share Stock Merger Consideration (as defined below) multiplied by the number of shares of Common Stock of the Company represented by the Certificates.

(b) Pending such surrender and exchange, a holder's Certificates shall be deemed for all purposes (other than the exchange contemplated by this Section 1.5) to evidence such holder's right to receive the Merger Payment. Upon surrender of a Certificate, together with such documents as may be reasonably requested by Dearborn, such Certificate shall forthwith be cancelled.

(c) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, providing an indemnity against any claim that may be made against it with respect to such Certificate, Dearborn will issue in exchange for such lost, stolen or destroyed Certificate the Merger Payment to which the holders thereof are entitled pursuant to this Section 1.5.

(d) Notwithstanding any provision of this Agreement to the contrary, no holder of Shares shall be entitled to receive fractional shares of Dearborn Common Stock and shall receive in lieu thereof, cash in an amount equal to the product of (x) such fractional part of a share of Dearborn Common Stock multiplied by (y) $100.

(e) At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Shares thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates shall cease to have any rights with respect to Shares represented by such Certificates, except as otherwise provided in this Agreement or by applicable law.

Section 1.6 Merger Consideration.

(a) Aggregate Merger Consideration. Subject to the terms and conditions of this Agreement and to the adjustments set forth herein, the "Aggregate Merger Consideration" shall consist of:

(i) Thirty-Three Million Dollars ($33,000,000) in cash plus or minus, as applicable, the Estimated Cash Working Capital Adjustment (as defined below) minus the product of .6 multiplied by the Closing Date Debt (as defined below) (the "Aggregate Cash Merger Consideration"); and

(ii) 220,000 shares of common stock, $.001 par value per share, of Dearborn (the "Dearborn Common Stock") plus or minus, as applicable, the Estimated Stock Working Capital Adjustment (as defined below) minus the number of shares of Dearborn Common Stock (rounded to the nearest whole number) obtained by dividing (x) the product obtained by multiplying the Closing Date Debt by .4 by (y) 100 (the "Aggregate Stock Merger Consideration").

(b) Per Share Merger Consideration. Subject to the terms and conditions of this Agreement and to the adjustments set forth herein, the "Per Share Merger Consideration" shall consist of:

(i) The dollar value obtained by dividing the Aggregate Cash Merger Consideration by the number of shares of Common Stock issued and outstanding immediately prior to the Effective Time (the "Per Share Cash Merger Consideration"); and

(ii) The number of shares of Dearborn Common Stock obtained by dividing the Aggregate Stock Merger Consideration by the number of shares of Common Stock issued and outstanding immediately prior to the Effective Time (the "Per Share Stock Merger Consideration").

(c) Aggregate Holdback Amount. Subject to the terms and conditions of this Agreement and to the adjustments set forth herein, the "Holdback Amount" shall consist of:

(i) $6,600,000 (the "Cash Holdback Amount"); and

(ii) 44,000 shares of Dearborn Common Stock (the "Stock Holdback Amount").

Section 1.7 Holdback.

(a) Holdback Amount. Subject to Section 1.6, this Section 1.7 and Section 9.8, the Cash Holdback Amount and the Stock Holdback Amount (collectively, the "Holdback Amount") shall be withheld at Closing by Dearborn from the Merger Payment and the Per Share Merger Consideration otherwise payable to Xxxxxxxx and Xxxxxxx, with 90% of the Cash Holdback Amount and the Stock Holdback Amount to be withheld from Xxxxxxxx and 10% of the Cash Holdback Amount and the Stock Holdback Amount to be withheld from Xxxxxxx. Subject to the final two sentences of this Section 1.7(a), Section 1.7(b) and Section 9.8, on the 548^th day following the Closing Date, Dearborn shall distribute to Xxxxxxxx and Xxxxxxx, respectively, 90% and 10% of (i) one half of the Cash Holdback Amount by wire transfer of immediately available funds and (ii) certificates representing one half of the shares of Dearborn Common Stock constituting the Stock Holdback Amount. Subject to the final two sentences of this Section 1.7(a), Section 1.7(b) and Section 9.8, on the second anniversary of the Closing Date, Dearborn shall distribute to Xxxxxxxx and Xxxxxxx, respectively, 90% and 10% of (i) the remainder of the Cash Holdback Amount by wire transfer of immediately available funds and (ii) certificates representing the remainder of the shares of Dearborn Common Stock constituting the Stock Holdback Amount. Each such date is referred to herein as a "Holdback Payment Date". Notwithstanding anything in this Section 1.7(a) to the contrary, if the Purchaser has given written notice to Xxxxxxxx of one or more claims pursuant to Section 1.7(b) or Section 9.2 of this Agreement and all such claims have not been resolved prior to the relevant Holdback Payment Date, Dearborn may withhold from its payment of the portion of the Holdback Amount otherwise payable on the relevant Holdback Payment Date, pending resolution of such claims, an amount of cash and shares of Dearborn Common Stock that represents Dearborn's good faith estimate of the amount to which it would be entitled if it prevailed with respect to such claims (with the allocation of such amount between the Cash Holdback Amount and the Stock Holdback Amount to be determined pursuant to Section 9.9). If, upon final resolution of all such claims, the aggregate amount withheld by Dearborn pursuant to this Section 1.7(a) is greater than the Sellers' aggregate liability with respect to all such claims then Dearborn shall distribute to Xxxxxxxx and Xxxxxxx an amount in cash or Dearborn Common Stock, as applicable, equal to such difference, with 90% of such amounts distributed to Xxxxxxxx and 10% of such amounts distributed to Xxxxxxx.

(b) Path 15 Performance Set-Off. A portion of the Holdback Amount shall be subject to forfeiture by the Sellers and retention by the Purchaser as set forth in this Section 1.7(b):

(i) if the Aggregate Gross Margin actually received by the Company pursuant to the Engineering, Procurement and Construction of Los Xxxxx-Xxxxx 000-xX Transmission Line (Path 15) Contract (the "Path 15 Contract") as of the later of (x) the 90^th day following completion of the Path 15 Contract and (y) payment to the Company of all retainage and retention it is due and settlement of all claims and disputes with respect to the Path 15 Contract is less than $[*] but greater than $[*], then $2,750,000 of the Holdback Amount shall be forfeited and shall be retained by the Purchaser (with the allocation of such amount between the Cash Holdback Amount and Stock Holdback Amount to be determined pursuant to Section 9.9); and

(ii) if the Aggregate Gross Margin actually received by the Company pursuant to the Path 15 Contract as of the later of (x) the 90^th day following completion of the Path 15 Contract and (y) payment to the Company of all retainage and retention it is due and settlement of all claims and disputes with respect to the Path 15 Contract is less than $[*], then $5,500,000 of the Holdback Amount shall be forfeited and shall be retained by the Purchaser (with the allocation of such amount between the Cash Holdback Amount and Stock Holdback Amount to be determined pursuant to Section 9.9).

*: This information has been omitted based on a request for confidential treatment. The omitted portions have been separately filed with the Securities and Exchange Commission.

(c) The Cash Holdback Amount shall bear simple interest from the Closing Date through the date of payment at the six month London Interbank Offered Rate ("LIBOR") as published in the Wall Street Journal as of the Closing Date, which rate shall adjust on the first Business Day of every sixth month after the Closing Date to the then current LIBOR; provided, however, that interest will be computed as if only such portion of the Cash Holdback Amount, if any, as is ultimately paid to Xxxxxxxx and Xxxxxxx in accordance with the terms of this Agreement was outstanding since the Closing Date.

(d) All distributions and dividends, whether in the form of cash, securities or other property, issued on or with respect to the Stock Holdback Amount and all other dividends and distributions thereon shall be subject to set-off in accordance with the terms of this Agreement and shall constitute part of the Stock Holdback Amount. Upon release of any portion of the Stock Holdback Amount, distributions and dividends paid on the stock released shall also be released. Prior to set-off, if any, in accordance with the terms of this Agreement, Xxxxxxxx and Xxxxxxx, as applicable, shall be treated as the beneficial owner of the Stock Holdback Amount for tax purposes. Prior to set-off, if any, in accordance with the terms of this Agreement, all voting rights with respect to the Stock Holdback Amount may be exercised by Xxxxxxxx or Xxxxxxx, as applicable, in accordance with the Delaware General Corporation Law. In the event of forfeiture or set-off in accordance with the terms of this Agreement, Dearborn is authorized to use the blank stock powers to effect the transfer of the Stock Holdback Amount to Dearborn or the Indemnified Party entitled thereto. In the event of forfeiture or set-off in accordance with the terms of this Agreement, Xxxxxxxx and Xxxxxxx shall execute such additional documents and instruments as reasonably requested by Dearborn or the Indemnified Party to effect the transfer of the Stock Holdback Amount.

Section 1.8 Working Capital Adjustment.

(a) Not less than three (3) Business Days prior to the scheduled Closing, the Company, after consultation with the Purchaser, will deliver to the Purchaser a notice indicating its good faith estimate of the Net Working Capital of the Company as of the Cut-Off Date, (the "Estimated Net

Working Capital"), along with a certificate of a duly authorized officer of the Company certifying the foregoing.

(b) The "Estimated Working Capital Adjustment" shall be the dollar value (whether positive or negative) obtained by subtracting $2,700,000 from the Estimated Net Working Capital, which, if positive, shall be added to the Aggregate Merger Consideration and, if negative, shall be subtracted from the Aggregate Merger Consideration. The "Estimated Cash Working Capital Adjustment" shall equal the dollar value (whether positive or negative) obtained by multiplying the Estimated Working Capital Adjustment by 0.6. The "Estimated Stock Working Capital Adjustment" shall equal the number of shares (whether positive or negative, rounded to the nearest whole number) of Dearborn Common Stock obtained by dividing (x) the product obtained by multiplying the Estimated Working Capital Adjustment by 0.4 by (y) 100.

Section 1.9 Post-Closing Adjustment.

(a) As promptly as practicable after the Closing (but in no event later than sixty (60) Business Days following the Closing Date), Dearborn shall, after consultation with Xxxxxxxx and the financial officer of the Company responsible for preparation of the calculation of Estimated Net Working Capital, cause to be prepared and delivered to Xxxxxxxx (x) the balance sheet of the Company as of the close of business on the Cut-Off Date, prepared in accordance with GAAP consistently applied (except to the extent that the line items contained therein vary from GAAP as set forth in the definition of Net Working Capital, in which case, preparation of such line items shall be as so varied) (the "Cut-Off Date Balance Sheet"), and (y) a calculation of (1) the Cut-Off Date Net Working Capital based on the Cut-Off Date Balance Sheet and (2) the Adjustment Amount (the "Adjustment Amount Calculation"), specifying in reasonable detail such calculations.

(i) Within ten (10) Business Days after delivery to Xxxxxxxx of the Cut-Off Date Balance Sheet and the Adjustment Amount Calculation, Xxxxxxxx shall have the right to furnish to Dearborn a statement (the "Objection Notice") setting forth in reasonable detail any objections he has to the Cut-Off Date Balance Sheet and the Adjustment Amount Calculation. Xxxxxxxx may object to the Cut-Off Date Balance Sheet and the Adjustment Amount Calculation solely on the basis of computational errors or that it was not prepared in accordance with GAAP, as modified by the definition of Net Working Capital. If no Objection Notice is delivered to Dearborn within such 10 Business Day period or if Xxxxxxxx notifies Dearborn in writing that the Cut-Off Date Balance Sheet and the Adjustment Amount Calculation is acceptable, then the Cut-Off Date Balance Sheet and the Adjustment Amount Calculation shall be deemed to have been accepted by the Sellers and shall become final and binding upon the parties hereto.

(ii) If within thirty (30) Business Days after the delivery of the Objection Notice, Dearborn and Xxxxxxxx are unable to agree to the Cut-Off Date Balance Sheet, an Adjustment Amount and Adjustment Amount Calculation, the Chicago office of PricewaterhouseCoopers LLP or, if it is unable or unwilling to serve, another nationally recognized accounting firm mutually acceptable to Dearborn and Xxxxxxxx (the "Independent Firm") shall be engaged to resolve any disputes regarding the Cut-Off Date Balance Sheet, the Adjustment Amount or the Adjustment Amount Calculation. Dearborn and Xxxxxxxx will direct the Independent Firm to render a determination within twenty (20) Business Days of its retention, and Dearborn and Xxxxxxxx and their respective agents will cooperate with the Independent Firm during its engagement. The Independent Firm will consider only those issues related to the Cut-Off Date Balance Sheet, the Adjustment Amount or Adjustment Amount Calculation that Dearborn and Xxxxxxxx have been unable to resolve. The determination of the chosen Independent Firm will be conclusive and shall become final and

binding upon the parties hereto and any amounts owing as a result thereof shall be paid in accordance with subparagraph (b) below. The Sellers (jointly and severally) and Dearborn shall each pay one half of the fees and expenses of such Independent Firm.

(b) If the Adjustment Amount is a positive number, Dearborn shall pay to the Sellers within five (5) Business Days of the final determination of the Adjustment Amount in accordance with subparagraph (a) above the Cash Adjustment Amount (with simple interest from the Closing Date through the date of payment at the Applicable Interest Rate) and the Stock Adjustment Amount. If the Adjustment Amount is a negative number, the Sellers shall jointly and severally pay to Dearborn within five (5) Business Days of the final determination of the Adjustment Amount in accordance with subparagraph (a) above the Cash Adjustment Amount (with simple interest from the Closing Date through the date of payment at the Applicable Interest Rate) and the Stock Adjustment Amount. The "Cash Adjustment Amount" shall equal the dollar value obtained by multiplying the absolute value of the Adjustment Amount by 0.6. The "Stock Adjustment Amount" shall equal the number of shares (rounded down to the nearest whole number) of Dearborn Common Stock obtained by dividing (x) the product obtained by multiplying the absolute value of the Adjustment Amount by 0.4 by (y) 100.

Section 1.10 Withholding. Notwithstanding anything herein to the contrary, Dearborn or InfraSource, on behalf of the Company, shall each (without duplication) be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares such amounts as required to be deducted and withheld with respect to any of the Transactions under any provision of Federal, state, local or foreign tax law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made.

Section 1.11 Adjustments to Prevent Dilution. In the event of any reclassification, stock split (including a reverse split), stock dividend or recapitalization affecting the Dearborn Common Stock, the Per Share Stock Merger Consideration and the denominator used in all formulae herein to arrive at numbers of shares of Dearborn Common Stock will be adjusted appropriately to provide to the holders of Shares the same economic effect as contemplated by this Agreement prior to such event.

Section 1.12 Further Actions. If, at any time after the Effective Time, the Surviving Corporation considers or is advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties, or assets of either the Company or Merger Sub, or otherwise to carry out the intent and purposes of this Agreement, the officers and directors of the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of each of the Company and Merger Sub, all such deeds, bills of sale, assignments and assurances and to take and do, in the name and on behalf of each of the Company and Merger Sub, all such other actions and things as the Board of Directors of the Surviving Corporation may determine to be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out the intent and purposes of this Agreement.

If any such Pre-Cut-Off Period Tax Returns are due after the Cut-Off Date, the Sellers shall submit drafts of such returns to the Purchaser for its review at least 10 days prior to the due date (taking into account extensions thereof) of any such Tax Return, provided, however, that such drafts of any

If and to the extent the Company actually receives the Refunds, it shall repay the Refunds so received to the Sellers in accordance with Section 11.4, net of all expenses of Company; provided that the Sellers, upon the request of the Company or the Purchaser, shall promptly return the Refunds (plus penalties, interest or other charges) to the Company in the event the Company is required to repay such Refunds.

(a) Except for indemnification claims against the Sellers pursuant to Sections 9.2(c), (d) and (e), the Sellers will have no liability for indemnification until the total of all Damages for which the Sellers are liable exceeds $250,000 (the "Minimum Threshold"). Once the Minimum Threshold has been exceeded, the Sellers shall be liable for all Damages, including the first $250,000. The Purchaser will have no liability for indemnification until total of all Damages for which the Purchaser is liable exceeds the Minimum Threshold after which the Purchaser shall be liable for all Damages, including the first $250,000.

(b) The aggregate amount of Damages payable by the Sellers in respect of the Business Representations and Warranties shall not exceed $13,750,000. The aggregate amount of Damages payable by the Sellers shall not exceed the Purchase Price.

(c) Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement shall limit any remedy of the Purchaser or Sellers at law or in equity for fraud or in which the Purchaser or Sellers may seek specific performance or other equitable relief.

(d) Notwithstanding anything in this Agreement to the contrary, no Seller shall be liable to Dearborn or the Company in connection with the Transactions for any amount in excess of the actual Merger Payment received by such Seller.

(e) The parties acknowledge and agree that the provisions of Section 1.9, this Article 9 and the provisions of Section 1.7 regarding the application of the Holdback Amount shall constitute the exclusive remedies of the parties with respect to the Transactions regarding any claim for Damages.

(f) The amount of any Damages for which indemnification is provided under this Article IX shall be net of any amounts actually recovered by the Indemnified Party under insurance policies with respect to such Damages.

(g) The amount of any Damages for which indemnification is provided under this Article IX shall be net of any Tax Benefit with respect to such Damages. The reduction in the Indemnifying Party's liability under this Agreement to provide indemnification for any Tax Benefit actually realized shall be effected by a payment of such Tax Benefit by the Indemnified Party to the Indemnifying Party on the date that the Tax Group of which the Indemnified Party is a member or the Indemnified Party, as the case may be, files the Tax Return on which such Tax Benefit is actually realized.

(h) Notwithstanding anything in this Agreement to the contrary, no Seller shall be liable to any Indemnified Party for Damages arising, directly or indirectly, from or in connection with (a) the terms of, abandonment of, or failure to undertake a public offering of Dearborn Common Stock or (b) violation of federal, state or foreign laws applicable to a public offering of Dearborn Common Stock to the extent that such violation was the result of a representation or warranty in this Agreement that was true and correct as of the Closing Date.

Section 9.5 Procedure for Indemnification—Third Party Claims. Promptly after receipt by an indemnified party under Section 9.2 or Section 9.3 (an "Indemnified Party") of notice of commencement of any third-party claim that may give rise to an indemnification obligation under this Article IX, such Indemnified Party will give notice to each party against whom indemnity may be sought (an "Indemnifying Party") in writing of the commencement of such claim together with the estimated amount of such claim (if known), and the Indemnifying Party or Parties shall have the right to assume the defense (at the Indemnifying Party or Parties' expense) of any such claim through counsel of the Indemnifying Party's or Parties' own choosing by so notifying the Indemnified Party within 30 days of the first receipt by any Indemnifying Party of such notice from the Indemnified Party; provided, however, that any such counsel shall be reasonably satisfactory to the Indemnified Party. Failure to give notice of commencement of a claim shall not affect the indemnification obligations hereunder except to the extent of actual and material prejudice determined by a final judgment of a court of competent jurisdiction no longer subject to review or appeal. Each Indemnified Party shall have the right to employ separate counsel in such claim and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of each Indemnified Party unless: (i) the Indemnifying Party has agreed to pay such expenses; or (ii) the Indemnifying Party has failed promptly to assume the defense and employ counsel reasonably satisfactory to such Indemnified Party; or (iii) the named parties to any such action, claim or proceeding (including any impleaded parties) include any Indemnified Party and the Indemnifying Party or an Affiliate of the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that either (x) there may be one or more legal defenses available to it which are different from or in addition to those available to the Indemnifying Party or such Affiliate or (y) a conflict of interest may exist if such counsel represents such Indemnified Party and the Indemnifying Party or its Affiliate; provided, that, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel in the circumstances described in clause (i), (ii) or (iii) above, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party; provided, however, that the Indemnifying Party shall not, in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be responsible hereunder for the fees and expenses of more than one such firm of separate counsel (in addition to any local counsel), which counsel shall be designated by such Indemnified Party. With respect to any Tax Claim that involves any Straddle Period, the Purchaser shall control the conduct of any such Tax Claim, through counsel of the Purchaser's own choosing and the Purchaser shall have all rights to settle,

compromise and/or concede such Tax Claim. Without the consent of the Indemnified Party, the Indemnifying Party or Parties shall not consent to, and the Indemnified Party shall not be required to agree to, the entry of any judgment or enter into any settlement unless such judgment or settlement (i) includes as an unconditional term thereof the giving of a release from all Liability with respect to such claim by each claimant or plaintiff to each Indemnified Party that is the subject of such third-party claim, (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of an Indemnified Party and (iii) in the case of any Tax Claim, such judgment or settlement does not and will not, in the reasonable determination of the Purchaser, give rise or result in an increase in any Tax liability of the Purchaser, the Company, or any of their Affiliates. If notice is given to an Indemnifying Party of the commencement of a claim and the Indemnifying Party does not, within 30 days after the Indemnified Party's notice is given, give notice to the Indemnified Party of its election to assume the defense of such claim, the Indemnifying Party will be bound by any determination made in such claim or any compromise or settlement effected by the Indemnified Party.

Section 9.6 Establishment and Contesting of Indemnification Liability. To be effective, any claim for indemnification by an Indemnified Party must be made by a written notice (a "Notice of Claim") to the Indemnifying Party or Parties, given in accordance with the provisions of Section 11.3 hereof. Furthermore, any claim for indemnification must be made by no later than the expiration of the applicable periods set forth in Section 9.1 above, if any, and if an Indemnified Party has made such a claim prior to the expiration of the applicable period set forth in Section 9.1 above, if any, then, subject to the limitations set forth in Section 9.4 above, the Indemnified Party shall be entitled to recover the full amount of its Damages even if that amount is not finally determined until after such expiration. Upon receipt of a Notice of Claim, the Indemnifying Party or Parties shall have twenty (20) Business Days to contest their indemnification obligation with respect to such claim, or the amount thereof, by written notice to the Indemnified Party (a "Contest Notice"). Such Contest Notice shall specify the reasons or bases for the objection of the Indemnifying Party or Parties to the claim. If no such Contest Notice is given within such twenty (20) Business Day period, the obligation of the Indemnifying Party or Parties to pay the amount of the Damages incurred by the Indemnified Party in connection with the claim shall be deemed established and accepted by the Indemnifying Party or Parties. If, on the other hand, the Indemnifying Party or Parties contest a Notice of Claim within such twenty (20) Business Day period, the Indemnified Party and the Indemnifying Party or Parties shall thereafter for at least ten (10) Business Days attempt in good faith to resolve their dispute by mutual agreement. Upon final determination of the amount of the Damages that is the subject of an indemnification claim (whether such determination is the result of the Indemnifying Party's or Parties' acceptance of, or failure to contest, a Notice of Claim, or a resolution of any dispute with respect thereto by agreement of the parties or otherwise), the Indemnifying Party or Parties shall be obligated to pay the amount of Damages to the Indemnified Party within two (2) Business Days of such final determination of the amount of the Damages due by the Indemnifying Party or Parties.

Section 9.7 Tax Effect of Indemnification Payments. All indemnity payments made pursuant to this Agreement shall be treated for all Tax purposes as adjustments to the Merger Payment.

Section 9.8 Right To Set-Off. Upon notice to the Sellers specifying in reasonable detail the basis for such set-off, the Purchaser may elect to set-off any amounts to which it may be entitled under this Agreement against the Aggregate Holdback Amount. Purchaser's sole remedy for the failure of the Company to meet the Aggregate Gross Margin under the Path 15 Contract shall be the forfeiture of the Holdback Amount in accordance with Section 1.7(b). Neither the exercise of nor the failure to exercise such right of set-off will constitute an election of remedies or limit the Purchaser in any manner in the enforcement of any other remedies that may be available to it.

Section 9.9 Payment; Dearborn Stock. Within ten (10) Business Days after the final determination of the amount of Damages that is the subject of an indemnification claim against the Sellers (whether such determination is the result of the Indemnifying Party's or Parties' acceptance of,

or failure to contest, a Notice of Claim, or a resolution of any dispute with respect thereto by agreement of the parties or otherwise), and within ten (10) Business Days prior to each Holdback Payment Date, Dearborn shall submit to Xxxxxxxx its good faith estimate of the fair market value of a share of Dearborn Common Stock as of such date. Within ten (10) Business Days of receipt of such notice, Xxxxxxxx shall submit to Dearborn Xxxxxxxx'x irrevocable election as to whether the indemnity payment shall be made in cash or shares of Dearborn Common Stock or a specified combination thereof, or what combination of cash and shares of Dearborn Common Stock shall be withheld from a Holdback Payment pending resolution of the pending claim (which election shall also apply to the ultimately determined indemnification claim). If such election is not timely received by Dearborn, Dearborn may determine in its sole discretion whether the indemnity claim shall be satisfied, and whether the Holdback Amount retained on a Holdback Payment Date shall be, in cash or shares of Dearborn Common Stock at the valuation specified in its notice, or a combination thereof. If Xxxxxxxx disagrees in good faith with Dearborn's determination of the fair market value of Dearborn Common Stock but has elected to satisfy the obligation to make the indemnity payment with shares of Dearborn Common Stock, Dearborn and Xxxxxxxx shall engage the Independent Firm to make such determination, and any fees, costs and expenses of the Independent Firm in connection therewith, or otherwise associated with determining the fair market value of the Dearborn Common Stock, shall be borne by the Indemnifying Party, and the determination of the Independent Firm shall be binding.

Section 9.10 No Right of Contribution. The Sellers acknowledge and agree that, upon and after the Closing, the Company shall not have any liability or obligation to indemnify, save or hold harmless or otherwise pay, reimburse or make any Indemnified Party whole for or on account of any claim for indemnification pursuant to Section 9.2 or any untruth, inaccuracy or incorrectness of, or other breach of, any representation or warranty or the nonfulfillment, nonperformance, nonobservance or other breach or violation of, or default under, any covenant or agreement made by the Sellers or the Company in this Agreement, and no Seller shall have any right of contribution against the Company in respect of such matters.

Section 11.6 Entire Agreement; No Third Party Beneficiaries.

If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, the parties agree that the court making such determination shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.

Section 11.8 Arbitration; Legal Proceedings; Specific Performance Submission of Controversy to Arbitration.

(a) Except as provided in Section 1.9, any dispute, claim or controversy arising out of or relating to this Agreement, including the breach, termination or validity thereof and the arbitrability of any claim thereunder (a "Dispute"), shall be settled by final and binding arbitration in the City of Los Angeles of the State of California, under the then effective Commercial Arbitration Rules of the American Arbitration Association ("AAA"), (the "Rules") as modified by this Agreement. Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction. The award rendered by the arbitrator shall be final and binding on the parties. There shall be one arbitrator who shall be appointed by Dearborn and Xxxxxxxx within twenty (20) days of receipt by the respondent(s) of the demand for arbitration. If Dearborn and Xxxxxxxx are unable to timely agree on one arbitrator, they shall ask the AAA to appoint one in accordance with the listing, striking and ranking procedure in the Rules and such appointment shall be binding on the parties. The arbitrator shall have the authority to award any remedy or relief that a court in the State of Delaware could order or grant, including specific performance of any obligation created under this Agreement, the issuance of an injunction or other provisional relief, or the imposition of sanctions for abuse or frustration of the arbitration process. The arbitral tribunal shall apply the law of the State of Delaware in deciding the merits of any Dispute, except, insofar as applicable, the relevant provision of the ABCA. The arbitration award will be in writing. By agreeing to arbitration, the parties do not intend to deprive any court of its jurisdiction to issue a pre-arbitral injunction, pre-arbitral attachment, or other order in aid of arbitration proceedings and the enforcement of any award. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitral tribunal shall have full authority to grant provisional remedies and to direct the parties to request that any court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any party to

respect the arbitral tribunal's orders to that effect. In addition to damages, the arbitral tribunal may award any remedy provided for under applicable law and the terms of this Agreement, including, without limitation, specific performance or other forms of injunctive relief.

(b) Arbitration to Be Expeditious. It is the intent of the parties that any arbitration shall be concluded as quickly as reasonably practicable. Unless Dearborn and Xxxxxxxx otherwise agree, once commenced, the hearing on the disputed matters shall be held four (4) days a week until concluded, with each hearing date to begin at 9:00 a.m. and to conclude at 5:00 p.m. The arbitrator shall use all reasonable efforts to issue the final award or awards within a period of five (5) Business Days after closure of the proceedings. Failure of the arbitrator to meet the time limits of this Section 11.8(b) shall not be a basis for challenging the award.

(c) Discovery and Certain Evidentiary Matters. Consistent with the expedited nature of arbitration, each party will, upon the timely written request of the other party, promptly provide the other with copies of documents relevant to the issues raised by any claim or counterclaim. Upon the timely request of a party, the arbitrator shall have the discretion to order examination by deposition of witnesses to the extent the arbitrator deems such discovery relevant and appropriate. In considering the relevancy, materiality, and admissibility of evidence, the arbitrators shall take into account, among other things, applicable principles of legal privilege, including the attorney-client privilege, the work product doctrine, and the self-evaluative privilege, and appropriate protection of confidential information.

(d) Costs of Arbitration. Xxxxxxxx and Dearborn shall share equally the fees and expenses of the arbitrator.

(e) Jurisdiction and Process. Each party hereto hereby submits to the exclusive jurisdiction of any Delaware federal court and if the court lacks jurisdiction over such proceeding, to the exclusive jurisdiction of any Delaware state court (collectively, the "Delaware Courts"), for the purpose of an order to compel arbitration and for provisional remedies or other relief in aid of arbitration, and to the non-exclusive jurisdiction of the Delaware Courts for the enforcement of any award issued hereunder. Each party hereby submits to personal jurisdiction in the Delaware Courts and irrevocably waives any objection as to venue therein, and further agrees not to plead or claim in any such court that any such proceeding has been brought in an inconvenient forum.

(f) Specific Performance. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy they are entitled pursuant to this Agreement.

Section 11.9 Time of Essence. Each of the parties hereto hereby agrees that, with regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

Section 11.10 Extension; Waiver. At any time prior to the Closing Date, the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties of the other parties contained in this Agreement or in any document delivered pursuant to this Agreement or (c) waive compliance by the other parties with any of the agreements or conditions contained in this Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party; provided, that a waiver by the Sellers shall be valid if signed by the Sellers. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 11.11 Election of Remedies. Neither the exercise of nor the failure to exercise a right of set-off or to give notice of a claim under this Agreement by any party hereto will constitute an election of remedies by, or limit in any manner the enforcement of any other remedies that may be available to, such party, whether at law or in equity.

Section 11.12 Assignment. Neither this Agreement not any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written content of the other parties, except that the Purchaser may assign, any or all of its rights and interests hereunder to any Affiliate of the Purchaser (but no such assignment shall relieve Purchaser of its obligations hereunder). Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

Section 11.13 Further Assurances. The parties agree (a) to furnish upon request to each other such further information, (b) to execute and deliver to each other such other documents, and (c) to do such other acts and things, all as the other party may reasonably request for the purpose of carrying out the intent of this Agreement and the documents referred to in this Agreement.

Section 11.14 Representative. Each of the Sellers by execution of this Agreement appoints Xxxxxxxx, as his exclusive agent and attorney-in-fact (the "Representative") to give and receive notices and communications with respect to the provisions of this Agreement, and to agree to, negotiate, enter into settlements or compromises of matters arising under this Agreement, and to take any and all actions necessary or appropriate in the judgment of the Representative to be taken on behalf of the Sellers under this Agreement. Such agency is irrevocable and coupled with an interest. Notices or communications to or from the Representative shall constitute notice to or from the Sellers in respect of matters under in this Agreement. The Sellers agree that a decision, act, consent or instruction of the Representative shall constitute a decision of all the Sellers, and shall be final, binding and conclusive upon each Seller, and the Purchaser may rely upon any decision, act, consent or instruction of the Representative as being the decision, act, consent or instruction of the Sellers, except that the Representative has no authority to waive the provisions of Section 9.4(d) hereof.

Section 11.15 Joint and Several Liability. InfraSource and Dearborn shall be jointly and severally liable for Dearborn's payment obligations pursuant to this Agreement.
