17

(A) accept such Preliminary Post-Closing Payment Amount, in which case (1) such Preliminary Post-Closing Payment Amount shall be deemed final and shall be considered the “Post-Closing Payment Amount” for purposes of this Agreement and (2) (x) if the Post-Closing Payment Amount is positive, Buyer shall pay to Sellers, within five (5) days of confirmation of the Post-Closing Payment Amount, by wire transfer of immediately available funds to one or more accounts designated by Sellers, an amount equal to the Post-Closing Payment Amount or (y) if the Post-Closing Payment Amount is negative (in which case, the “Post-Closing Payment Amount” for purposes of this clause (y) shall be deemed to be equal to the absolute value of such amount), Sellers shall pay to Buyer, within five (5) days of confirmation of the Post-Closing Payment Amount, by wire transfer of immediately available funds to one or more accounts designated by Buyer, an amount equal to the Post-Closing Payment Amount; or

Section 2.2 Allocation.

(a) On the Closing Date, Buyer shall prepare and deliver to Sellers, using and based upon the best information available to Buyer, an initial allocation statement (the “Initial Allocation Statement”) reflecting the allocation of the Base Purchase Price among the Interests including, where applicable, a further allocation of the Base Purchase Price to any interests in Indirect Subsidiaries held by a DEI Direct Subsidiary or Dominion Questar Direct Subsidiary (the “Initial Allocation”). As soon as reasonably practicable, but no later than thirty (30) days following the receipt of the Initial Allocation Statement, Sellers shall deliver to Buyer a written report containing any changes that Seller proposes to be made in such schedule (and specifying the reasons therefor in reasonable detail).

18

(b) Within thirty (30) days after the final determination of the Post-Closing Payment Amount, Buyer shall prepare and deliver to Sellers a statement (the “Final Allocation Statement”) reflecting the allocation of the final Purchase Price, as adjusted to reflect assumed liabilities and other amounts deemed paid by Buyer for federal income Tax purposes, among the Interests (the “Final Allocation”). To the extent required by Section 338 or 1060, the Final Allocation Statement shall include an allocation of that portion of the adjusted Purchase Price allocated to a DEI Direct Subsidiary or a Dominion Questar Direct Subsidiary among the separate classes of assets of such entity (and a further allocation of the Purchase Price attributable to an Indirect Subsidiary among the assets of such subsidiary) in a manner that is consistent with the allocation methodology provided by Section 338 or Section 1060 of the Code and the Treasury regulations promulgated thereunder, as the case may be. Within thirty (30) days following the receipt by Sellers of the Final Allocation Statement, Sellers shall review the Final Allocation and submit to Buyer in writing any objections or proposed changes to the Final Allocation Statement (an “Objections Notice”). Unless Sellers submit an Objections Notice on or before the expiration of such thirty (30) day period, the Final Allocation Statement prepared and delivered to Sellers pursuant to this Section 2.2(b) shall be deemed agreed upon by the Parties and shall be deemed conclusive for purposes of the Final Allocation.

(c) If Sellers timely submit an Objections Notice in accordance with Section 2.2(b), the Parties shall negotiate in good faith and use their Reasonable Efforts to resolve such dispute. In the event the Parties are unable to resolve any dispute with respect to the Final Allocation Statement within twenty (20) days after the delivery of the Objections Notice, neither Buyer nor Sellers will be bound by the Final Allocation Statement as prepared by Buyer, and each Party may independently (and in its sole discretion) (i) determine its own allocation of the Purchase Price between the ownership interests of each Sale Entity and, with respect to that portion of the adjusted Purchase Price to be allocated to each Sale Entity, among the separate classes of assets of such Sale Entity, and (ii) file its Tax Returns (and Tax Returns of its Affiliates) using alternative allocations of its choosing.

(d) If the Parties ultimately agree on the Final Allocation Statement, (i) such Final Allocation Statement shall be amended as, and to the extent, Buyer and Sellers agree to reflect any adjustment to the Purchase Price (as adjusted to reflect assumed liabilities and other amounts deemed paid by Buyer for federal income Tax purposes), (ii) except to the extent required to comply with audit determinations of any Taxing Authority with jurisdiction over a Party, Buyer and Sellers shall report the Contemplated Transactions for all required federal Income Tax and all other Tax purposes in a manner consistent with the Final Allocation, and (iii) no Party shall take any position in any Tax Return or Tax Proceeding that is inconsistent with the Final Allocation without the consent of the other Parties; provided, however, that no Party (or any of its Affiliates) shall be required to litigate before any court or defend in any administrative proceeding (including any Tax audit or examination) any proposed deficiency or adjustment by any Taxing Authority challenging such Final Allocation.

19

Buyer shall be entitled to deduct and withhold any amounts that are required to be deducted or withheld under any provision of applicable Law, and any amount so deducted or withheld will be remitted by Buyer to the applicable Taxing Authority, and shall be treated, for purposes of this Agreement, as having been paid to the Person in respect of which the deduction or withholding was made.

(c) All Employee Plans contributed to by a Sale Entity or any ERISA Affiliate intended to be qualified under Section 401 of the Code have filed for or received favorable determination letters with respect to such qualified status from the Internal Revenue Service. The determination letter for each such Employee Plan remains in effect, and, to Sellers’ Knowledge, any amendment made, or event relating to such an Employee Plan subsequent to the date of such determination letter, has not materially and adversely affected the qualified status of the Employee Plan.

(d) No Employee Plan that is subject to Title IV of ERISA (a “Title IV Plan”) or Section 430 of the Code is considered “at-risk”, within the meaning of Section 430(i)(4) of the Code, and to Sellers’ Knowledge, no condition exists which would be expected to result in an Employee Plan becoming “at-risk” as of the last day of the current plan year of any Title IV Plan or other Employee Plan subject to Section 430 of the Code. The PBGC has not instituted proceedings to terminate any Title IV Plan, and no other event or condition has occurred which might constitute grounds under Section 4042 of ERISA for the termination of, or the appointment of a trustee to administer, any such Title IV Plan.

Section 5.3 Certain Tax Matters.

(a) All Transfer Taxes incurred in connection with this Agreement and the Contemplated Transactions shall be borne one-half (1/2) by Buyer and one-half (1/2) by Sellers. Buyer shall file, to the extent required by applicable Tax Laws, all necessary Tax Returns and other documentation with respect to all such Transfer Taxes. To the extent required by applicable Tax Laws, Sellers or any of their Affiliates will join in the execution of any such Tax Returns or other documentation. The party not making that payment of Transfer Taxes to the Governmental Authority shall pay its share of such Transfer Taxes within five (5) days after demand therefor (which demand may be made before the payment of Taxes to a Governmental Authority) by the paying party.

(b) Any Tax Return to be prepared pursuant to the provisions of this Section 5.3(b) shall be prepared in a manner consistent with practices followed in prior years with respect to similar Tax Returns, except for changes required by changes in applicable Tax Laws or changes in fact (including the Section 338(h)(10) Election). Buyer shall not, and shall not cause or permit the Sale Entities or any of Buyer’s Affiliates to, (i) amend, refile or otherwise modify any Tax Return with respect to any of the Sale Entities for any Tax period or portion thereof ending on or prior to the Closing Date, or (ii) enter into any closing agreement, settle any Tax claim or assessment relating to any Sale Entity, surrender any right to claim a refund of Taxes, consent to any extension or waiver of the limitation period applicable to any Tax claim or assessment relating to any Sale Entity for any Pre-Closing Tax Period, or take any other similar action relating to the filing of any Tax Return or the payment of any Tax, in each instance without obtaining the prior written consent of Sellers, which consent may be withheld in Sellers’ sole discretion. The following provisions shall govern the allocation of responsibility as between the Parties for certain Tax matters following the Closing Date:

(i) Sellers shall prepare or cause to be prepared and file or cause to be filed all Income Tax Returns and all Non-Income Tax Returns for any of the Sale Entities for all Pre-Closing Tax Periods regardless of when they are to be filed. With respect to Non-Income Tax Returns filed after the Closing Date, Sellers

35

shall deliver to Buyer for its review and comment a copy of such Non-Income Tax Returns for its review as soon as reasonably possible. Sellers shall reasonably consider any comments provided by Buyer. Notwithstanding the foregoing, in the event Sellers and Buyer disagree with respect to any Non-Income Tax Return prepared by Sellers pursuant to this Section 5.3(b)(i), Sellers may file such Non-Income Tax Return reflecting the position Sellers determine, in their sole discretion, to be appropriate unless a different position is required by applicable Law. Except as otherwise provided in this Section 5.3 (including, for the avoidance of doubt, Section 5.3(b)(iii)), Sellers shall pay, or cause to be paid on each of the Sale Entities’ behalf, the Taxes payable by each of the Sale Entities with respect to all Pre-Closing Tax Periods, except to the extent of (A) Taxes that became due as any breach of any covenant, representation, warranty, undertaking or other obligation imposed on Buyer or its Affiliates pursuant to this Agreement (including, for this purpose, any of the Sale Entities) on or after the Closing Date and (B) the portion of any Transfer Taxes for which Sellers are not responsible pursuant to Section 5.3(a), and if Sellers pay Taxes described in clause (A) or (B) on behalf of the Sale Entities or Buyer, the Sale Entities or Buyer shall reimburse Sellers therefor within fifteen (15) days after the date on which the Taxes are paid. Notwithstanding any provision in this Agreement to the contrary, Sellers shall have sole discretion and control over any and all Income Tax Returns required to be filed by or in respect of a Sale Entity for a taxable period or portion thereof ending on or prior to the Closing Date.

(ii) Buyer shall prepare or cause to be prepared and file or cause to be filed any Non-Income Tax Returns of the Sale Entities for Tax periods that begin before or on the Closing Date and end after the Closing Date (a “Straddle Period”). Buyer shall deliver to Sellers Tax Returns pertaining to the Straddle Period for Sellers’ review at least fifteen (15) days before the date on which such Tax Return is required to be filed, or as soon as reasonably possible if the Tax Return is required to be filed within ninety (90) days following the Closing Date. Sellers shall review such Tax Returns within ten (10) days after the delivery of such Tax Returns. Sellers will be deemed to have approved such Tax Returns as prepared by Buyer if they fail to submit comments within such ten (10) day review period. If Sellers deliver comments to Buyer within such ten (10) day review period, Buyer and Sellers shall use good faith efforts to resolve any dispute in connection with such comments. In the event Buyer and Sellers are unable to agree on any such revisions within ten (10) days after Sellers provide their comments, Buyer and Sellers shall engage the Independent Auditor to resolve the matter, and the Independent Auditor’s determination shall be final and binding on the Parties. The Independent Auditor shall resolve the dispute within twenty (20) days after the item has been referred to it. Notwithstanding anything to the contrary in this Section 5.3(b)(ii), Buyer shall be entitled to file on behalf of the Sale Entities, or cause to be filed, the applicable Tax Return without having incorporated Sellers’ proposed changes if necessary to avoid a late filing of such Tax Return. If the Independent Auditor’s resolution of the dispute necessitates the amendment of a Tax Return filed in accordance with the previous sentence, then Buyer shall cause an amended Tax Return to be filed that reflects such resolution. The fees and expenses of the Independent Auditor shall be borne by each Party in the percentage inversely proportionate to the percentage of the total items submitted for dispute that are resolved in such Party’s favor.

36

(iii) Sellers shall pay, or cause to be paid, to Buyer within fifteen (15) days after the date on which Taxes are paid with respect to a Straddle Period an amount equal to the portion of such Taxes, if any, which relates to the portion of such Tax period ending on the Closing Date, after taking into account any prepayments or deposits made by or on behalf of a Sale Entity on or before the Closing Date. Notwithstanding the foregoing, Sellers shall have no liability or obligation to pay any Taxes becoming due as a result of any breach of any covenant, representation, warranty, undertaking or other obligation imposed on Buyer or its Affiliates pursuant to this Agreement (including, for this purpose, any of the Sale Entities) on or after the Closing Date. For purposes of this Section 5.3(b)(iii), in the case of any Taxes that are imposed and are payable for a Straddle Period, the portion of such Tax which relates to the portion of such Tax period ending as of the Closing Date shall, in the case of any Taxes imposed on a periodic basis (such as real property Taxes), be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction, the numerator of which is the number of days in the Tax period ending on and including the Closing Date and the denominator of which is the number of days in the entire Tax period. In the case of non-periodic Taxes (i.e., such as Taxes that are (w) based upon or related to income or receipts, (x) imposed in connection with any capital or debt restructuring, (y) imposed in connection with any sale, distribution, or other transfer or assignment of property (real or personal, tangible or intangible), or (z) payroll, withholding, excise and similar Taxes), the portion of such Tax which relates to the portion of such Tax period ending on the Closing Date shall be determined based on a closing of the books of the Sale Entities at the end of the Closing.

(iv) Sellers and Buyer agree that, except with respect to Tax incurred by Sellers upon the sale of the Interests to Buyer pursuant to this Agreement, Buyer shall be responsible for all Taxes incurred by or with respect to the Sale Entities, whether resulting from the assets or operations of the Sale Entities or otherwise, for all Tax periods beginning after the Closing Date (including the portion of any Straddle Period beginning immediately after the Closing Date) to the extent attributable to the direct or indirect interest acquired by Buyer. In the event Taxes for which Buyer is responsible under this Section 5.3(b)(iv) are reduced because of Tax payments made by Sellers or a Sale Entity on or before the Closing Date (whether through deposits, prepayments, credits, or otherwise), Buyer shall reimburse Sellers therefor within five (5) days after the date on which Buyer realizes the benefit of the reduction.

(c) Each Party shall provide the other Parties with such assistance as may reasonably be requested by the other Parties in connection with the preparation of any Tax Return, any audit or other examination by any Governmental Authority, or any judicial or administrative proceedings relating to liability for Taxes, and each will retain

37

and provide the requesting Party with any records or information which may be relevant to such return, audit or examination, proceedings or determination. Any information obtained pursuant to this Section 5.3 or pursuant to any other Sections hereof providing for the sharing of information relating to or review of any Tax Return or other schedule relating to Taxes shall be subject to the terms of the Confidentiality Agreement.

(d) Except as otherwise provide herein, in the case of any audit, examination, or other proceeding (a “Tax Proceeding”) with respect to (i) any Tax period ending on or before the Closing Date and (ii) with respect to any other Tax period ending after the Closing Date for which Sellers are or may be liable for any Taxes pursuant to this Agreement, Buyer shall inform Sellers in writing of such Tax Proceeding within ten (10) days after the receipt by Buyer of written notice thereof. In the event Buyer fails to timely provide Sellers with written notice of such Tax Proceeding, Sellers’ obligation to indemnify Buyer or its Affiliates hereunder shall be reduced to the extent of any Adverse Consequences arising as a result of such failure to notify. Buyer shall afford Sellers, at Sellers’ expense, the opportunity to control the conduct of such Tax Proceeding; provided, however, that Buyer shall have the right, at Buyer’s expense, to attend and participate in such Tax Proceeding, but only to the extent such Tax Proceeding pertains to a Sale Entity and does not involve Sellers or any of their Affiliates. If Sellers elect not to control the conduct of any such Tax Proceeding, Buyer shall control the conduct of such Tax Proceeding at Buyer’s expense, and Sellers shall have the right (at Sellers’ expense) to attend and participate in such Tax Proceeding. Neither Buyer nor Sellers shall settle or compromise such Tax Proceeding without the prior written consent of the other, such consent not to be unreasonably withheld, conditioned, or delayed. Notwithstanding any other provision in this Agreement to the contrary, Sellers shall have the sole right to control, settle, and compromise all Tax Proceedings related to Income Taxes of a Sale Entity for a Pre-Closing Tax Period, and Buyer shall have no right to participate to attend or participate in any such Tax Proceeding, or to receive copies of any correspondence or other information related to any Tax Proceeding to the extent such Tax Proceeding, correspondence, or other information includes or pertains to Sellers or any of their Affiliates.

(e) To the extent that a Sale Entity’s liability for Taxes for a taxable year or portion ending on or before the Closing Date (as computed in a manner consistent with Section 5.3(b)(iii), and after giving effect to any Tax credits or Tax abatements) is less than the amount of estimated Taxes paid by or on behalf of such Sale Entity with respect to all or a portion of such taxable year or period, Buyer shall pay Sellers the difference within two (2) days of filing the relevant Tax Return that reflects such Tax.

(f) Without duplication of amounts payable to Sellers pursuant to this Section 5.3, any refund of Taxes paid or payable by or with respect to the Sale Entities, shall be paid within two (2) Business Days of receipt as follows, or to the extent payable but not paid due to offset against other Taxes shall be paid by the Party receiving the benefit of the offset within two (2) Business Days of such offset as follows: (i) to Sellers if attributable to any Tax period or portion thereof ending on or before the Closing Date, or for any Straddle Period to the extent allocable, determined in a manner consistent with Section 5.3(b)(iii), to the portion of such Tax period beginning before and ending on the

38

Closing Date; and (ii) to Buyer if attributable to any Tax period or portion thereof beginning after the Closing Date or for any Straddle Period to the extent allocable, determined in a manner consistent with Section 5.3(b)(iii), to the portion of such Tax period beginning after the Closing Date. Buyer shall cooperate, and shall cause each of its Affiliates and the Sale Entities to cooperate, in obtaining any Tax refund that Sellers reasonably believes should be available, including through filing appropriate forms with the applicable Taxing Authority.

(g) Except as provided otherwise herein, none of the Sale Entities shall take, and none of Buyer or any of its Affiliates shall permit or otherwise allow any of the Sale Entities to take, any action on the Closing Date that is not in the ordinary course of the Sale Entities’ businesses, including, but not limited to, the merger or liquidation of any of the Sale Entities or the distribution of any property in respect of any of the Sale Entities’ stock, partnership interests or membership interests, without the prior written consent of Sellers, which consent may be withheld in Sellers’ sole discretion. For this purpose, an action taken effective as of the Closing Date shall be treated as having been taken on the Closing Date.

(h) Except as required by Law, neither Buyer nor any of its Affiliates shall (or shall cause or permit any of the Sale Entities to) take any action which could (A) increase Sellers’ (or any of its Affiliates) liability for Taxes (including any liability of Sellers to indemnify Buyer for Taxes pursuant to this Agreement) or (B) result in, or change the character of, any income or gain that Sellers (or any of its Affiliates) must report on any Income Tax Return.

(i) All Tax sharing agreements or arrangements that provide for the allocation, apportionment, sharing, or assignment of Tax liability between any of the Sale Entities and Sellers or Sellers’ Affiliates shall be terminated as of the Closing Date.

(j) Election Under Section 338(h)(10).

(i) Sellers and Buyer shall make, or cause to be made, a timely and effective joint election under Section 338(h)(10) of the Code and under any applicable similar provisions of state or local law with respect to the purchase of the interests in each Sale Entity specified by Buyer (all such elections being referred to collectively as the “Section 338(h)(10) Election”).

(ii) Buyer shall prepare Internal Revenue Service Form 8023, required schedules thereto and any similar forms necessary to effectuate the Section 338(h)(10) Election under applicable state and local laws (collectively, the “Section 338(h)(10) Election Forms”). Seller shall cooperate with Buyer in the preparation of the Section 338(h)(10) Election Forms and shall deliver duly completed, executed copies thereof on the Closing Date. Buyer and Seller shall cooperate with each other and take all actions necessary and appropriate (including filing such additional forms, Tax Returns, elections, schedules, and other documents as may be required) to effect and preserve the Section 338(h)(10) Election in accordance with Section 338 of the Code and the Treasury Regulations thereunder and comparable provisions of applicable state and local Tax laws and shall take no action inconsistent therewith except to the extent required pursuant to a “determination” as defined in Section 1313(a) of the Code or any similar provision of any state, foreign or local law.

Any actions of the Sale Entities or JV Companies occurring following the Effective Date which are required or permitted by this Agreement, including Actions permitted or consented to by Buyer pursuant to Section 5.4(a) shall automatically be deemed to amend and update any appropriate Schedule solely with respect to the representations and warranties of the Sellers and such amendment shall not be subject to, or included in, any determination of whether the provisions of Sections 6.2 or 9.1(c) have been satisfied or are applicable; provided, that such action does not result in a Material Adverse Effect. In the event of a Q-Pipe Termination, Sellers shall be permitted to amend and update any and all appropriate Schedules to reflect the exclusion of the Q-Pipe Companies from the Contemplated Transactions.

Section 5.6 Employee Matters.

(a) Buyer shall cause all Company Employees (other than Sale Entity Employees) to receive a Post-Closing Offer at least fifteen (15) Business Days prior to the Closing Date, with each such offer to be contingent and effective upon the Closing.

Each Transferred Non-Union Employee’s benefit under the applicable Post-Closing Salaried Pension Plan shall be at least equal to (A) minus (B), where: (A) equals the total accrued pension benefit for such Transferred Non-Union Employee under the Post-Closing Salaried Pension Plan,

45

calculated as of such Transferred Non-Union Employee’s retirement or termination date from the Post-Closing Employer and its Affiliates, taking into account service credit and compensation earned from the Post-Closing Employer, DEI or an ERISA Affiliate through the Closing Date, plus service credit and compensation earned under the Post-Closing Salaried Pension Plan from the Closing Date until such Transferred Non-Union Employee’s retirement or termination date; and (B) equals the accrued normal retirement benefit of such Transferred Non-Union Employee under the Dominion Energy Pension Plan as of the Closing Date. DEI will provide all necessary earnings history and information required to calculate the benefit under Part A and B of the formula as soon as reasonably practicable after the Closing Date.

(i) During the Continuation Period, Buyer shall cause the Post-Closing Employer to provide a level of retiree medical and life insurance benefits to each Transferred Non-Union Employee hired by Buyer and its Affiliates before October 1, 2015 not lower than the level of retiree medical and life insurance benefits available to each such Transferred Non-Union Employee immediately prior to the Closing.

(o) As of the Closing, DEI or each ERISA Affiliate shall take all necessary action to cause the defined contribution plans maintained by DEI or such ERISA Affiliate to fully vest the Company Employees in their account balances under such defined contribution plans.

Section 10.2 Procedure for Indemnification. Each claim for indemnification, including those claims resulting from the assertion of liability by Persons not parties to this Agreement, including claims by any Governmental Authority for penalties, fines and assessments, must be made by delivery by the Party to be indemnified (the “Indemnified Party”) to the Party responsible for the indemnification obligation (the “Indemnifying Party”) of written notice containing details reasonably sufficient to disclose to the Indemnifying Party the nature and scope of the claim including an estimate of the amount of claimed Adverse Consequences and copies of all relevant pleadings, documents and information within ten (10) Business Days after the Indemnified Party’s knowledge of such claim. Any failure in the delivery of such notice shall not affect the obligations of the Indemnifying Party, except to the extent that the rights and remedies of the Indemnifying Party are adversely affected or prejudiced as a result of the failure to give, or delay in giving, such notice. In the event that any Action is brought against an Indemnified Party for which the Indemnifying Party may be required to indemnify the Indemnified Party hereunder, the Action shall be defended by the Indemnifying Party and such defense shall include all appeals or reviews. The Indemnifying Party shall not make any settlement of any claims without the written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed, provided, however, that such consent shall not be required if (i) the settlement does not involve any finding or admission of any violation of Law or admission of any wrongdoing by the Indemnified Party, (ii) the sole relief is monetary damages, which the Indemnifying Party shall pay or cause to be paid concurrently with the effectiveness of such settlement, (iii) the settlement involves a full release of the claim and (iv) the settlement does not encumber any of the assets of any Indemnified Party or impose any restriction or condition that would apply to or materially adversely affect any Indemnified Party. If the Indemnified Party withholds its consent unreasonably, the Indemnified Party shall be obligated for any future expenses and excess settlement amounts. The Indemnified Party shall fully cooperate at its expense in connection with the defense of any such claims including, without limitation, reasonable access to the Indemnified Party’s records and personnel relating to such claim, and will have the right to participate in the defense of any claim by counsel of its own choosing and at its own expense.

Section 10.3 Survival. The representations and warranties of the Parties contained in this Agreement shall survive the Closing for a period of six (6) months after the Closing Date; provided, however, that (i) the representations and warranties set forth in Section 3.9 (Tax Matters) shall survive the Closing until the sixtieth (60th) day after expiration of the statute of limitations period applicable thereto, and (ii) the Fundamental Representations (other than Section 3.2(d), which shall survive for a period of two (2) years after the Closing Date) shall survive the Closing for a period of five (5) years after the Closing Date. The covenants and agreements of the Parties to be performed or complied with prior to the Closing shall survive the Closing for a period of ninety (90) days after the Closing Date and those covenants and agreements of the Parties that by their terms are to be performed or complied with after the Closing shall survive for a period of thirty (30) days after their expiration in accordance with their terms. No Indemnifying Party shall have any liability for any claim for indemnification made pursuant to Section 10.1(a) or 10.1(b) by an Indemnified Party hereunder unless the

61

Indemnified Party notifies such Indemnifying Party of such claim in writing, setting forth in reasonable detail the nature of the claim on or before the expiration of the time periods provided in the first sentence of this Section 10.3; provided that if no notice of a claim for indemnification made pursuant to Section 10.1(a) or 10.1(b) has been made within the time periods set forth above in this Section 10.3, then such claim for indemnification shall be waived.

Section 10.4 Exclusivity. Following the Closing, except for actual fraud or willful misconduct, the rights and remedies of Sellers and the Seller Indemnified Parties, on the one hand, and Buyer and the Buyer Indemnified Parties, on the other hand, for damages under this Article X are, solely as between Sellers and the Seller Indemnified Parties on the one hand, and Buyer and the Buyer Indemnified Parties on the other hand, exclusive and in lieu of any and all other rights and remedies for damages which Sellers and the Seller Indemnified Parties on the one hand, and Buyer and the Buyer Indemnified Parties on the other hand, may have under this Agreement or under applicable Laws with respect to the Contemplated Transactions, including any breach of this Agreement, warranty, tortious conduct or otherwise, and whether at common law, statute, strict liability, equity, or otherwise, and each Party agrees to waive to the fullest extent permitted by applicable Law, any claims or rights with respect thereto unless specifically provided for in this Section 10.4. Notwithstanding the foregoing, a Party may bring an Action to enforce this Article X.

Section 10.5 Limitation of Claims; Mitigation. Notwithstanding anything to the contrary contained herein:

(a) Except with respect to claims for breaches of Section 3.9 (Tax Matters) (each, a “Tax Representation”) and the Retained Liabilities, the maximum aggregate liability of Sellers under this Agreement shall not exceed an amount equal to the Base Purchase Price (the “Cap”); provided, however, that with respect to indemnification obligations of Sellers under Section 10.1(a)(i) (other than with regard to any breaches of any of Sellers’ Fundamental Representations or a Tax Representation) the Cap shall be an amount equal to ten percent (10%) of the Base Purchase Price.

(b) In no event shall Sellers have any liability to Buyer in respect of any indemnification obligations under Section 10.1(a)(i) or Section 10.1(a)(ii) unless and until such liabilities exceed, in the aggregate, $75,000,000.00 (the “Basket Amount”), and then only to the extent such liabilities are in excess of the Basket Amount, subject to the Cap; provided, that the Basket Amount limitation shall not apply to breaches of any of Sellers’ Fundamental Representation (other than with respect to Section 3.2(d)) or any Tax Representation.

(c) No representation or warranty made in Article III shall be deemed to be breached and no claim for indemnification pursuant to Section 10.1(a)(i) may be made unless the Adverse Consequences resulting from or arising out of any individual circumstance or occurrence that results in Adverse Consequences actually incurred or paid by a Buyer Indemnified Party exceed $5,000,000.00 (the “Per Claim Threshold”), and if such Adverse Consequences exceed the Per Claim Threshold, the full amount thereof (after taking into account the limitations set forth in this Article X) shall be taken into account in determining whether, and the extent to which, the Basket Amount has been met and, if the Basket Amount has been met, shall be subject to indemnification under this Article except to the extent limited by this Section 10.5; provided, that the Per Claim Threshold limitation shall not apply to breaches of any of Sellers’ Fundamental Representations or any Tax Representation.

62

(d) An Indemnified Party shall not be entitled to any indemnity payment for breaches of representations and warranties by the Indemnifying Party to the extent the Indemnified Party had knowledge of any event, action or circumstance giving rise to such breach prior to the Closing.

(e) Notwithstanding anything in this Agreement, (i) Sellers shall not be liable for any Adverse Consequences actually incurred or paid by a Buyer Indemnified Party to the extent that such Adverse Consequences arose from (A) a change in accounting or Law, policy or practice made after the Closing Date or (B) any Law not in force on the Closing Date, and (ii) no Party shall be responsible for Adverse Consequences with respect to any claim which is contingent unless and until such contingent claim becomes an actual liability of the Indemnified Party and is due and payable, so long as such claim was timely submitted pursuant to Section 10.3.

(f) Notwithstanding anything in this Agreement, no Party shall be liable under this Article X for an amount (i) to the extent, if any, that any Adverse Consequences giving rise to such amount results from a failure on the part of any Indemnified Party to exercise good faith in not jeopardizing or prejudicing the interests of the Indemnifying Party or otherwise arises out of any action taken or omitted to be taken by an Indemnified Party or (ii) unless and until all rights and remedies of an Indemnified Party under any other obligation of indemnification in its favor shall have first been exhausted, including using Reasonable Efforts to (A) secure payment from insurance policies that provide coverage with respect to such Adverse Consequences, and (B) secure reimbursement, indemnity or other payment from any third Person obligated by Contract or otherwise to reimburse, indemnify or pay the Indemnified Party with respect to such Adverse Consequences.

(g) Notwithstanding anything in this Agreement or any applicable Law to the contrary, it is understood and agreed by each of the Parties that no stockholder, member, partner, manager, officer, director, employee, consultant, agent, representative or Affiliate of any Party hereto shall have (i) any personal liability to any Buyer Indemnified Party or Seller Indemnified Party as a result of the breach of any representation, warranty, covenant or agreement contained in this Agreement or otherwise arising out of or in connection with the Contemplated Transactions, or (ii) any personal obligation to indemnify any Buyer Indemnified Party or any Seller Indemnified Party for any claims pursuant to this Article X, and Buyer, for itself and all other Buyer Indemnified Parties and each Seller, for itself and all other Seller Indemnified Parties, hereby waive and release and shall have no recourse against any of such Persons described in this Section 10.5(g) as a result of the breach of any representation, warranty, covenant or agreement contained herein or otherwise arising out of or in connection with the Contemplated Transactions. An Indemnified Party shall use Reasonable Efforts to mitigate all Adverse Consequences relating to an indemnifiable claim, including availing itself of any

63

defenses, limitations, rights of contribution, and other rights at law or equity, and shall provide such evidence and documentation of the nature and extent of such claim as may be reasonably requested by the Indemnifying Party. An Indemnified Party’s Reasonable Efforts shall include the reasonable expenditure of money, including the payment of any legal fees, to mitigate or otherwise reduce or eliminate any Adverse Consequences for which indemnification would otherwise be due under this Article X.

(h) An Indemnifying Party’s indemnification obligations under this Article X shall be reduced (but not below zero) to the extent that the Adverse Consequences related to a claim is covered by and paid to the Indemnified Party pursuant to (A) a reimbursement, indemnification or payment from a third Person with respect to such Adverse Consequences, or (B) insurance policies that provide coverage with respect to such Adverse Consequences.

(i) NOTWITHSTANDING ANY PROVISION IN THIS AGREEMENT TO THE CONTRARY, UNDER NO CIRCUMSTANCES SHALL ANY PARTY, OR ITS AFFILIATES, OR ITS OR THEIR STOCKHOLDERS, MEMBERS, PARTNERS, MANAGERS, DIRECTORS, OFFICERS, EMPLOYEES, CONSULTANTS, AGENTS OR REPRESENTATIVES, BE RESPONSIBLE OR LIABLE FOR AND NO PARTY SHALL BE ENTITLED TO SEEK, ANY INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, SPECULATIVE, SPECIAL OR CONSEQUENTIAL DAMAGES (INCLUDING, WITHOUT LIMITATION, DAMAGES RELATED TO DIMINUTION IN VALUE, LOST BUSINESS, LOST PROFITS, LOST REVENUE, LOST INCOME, LOSS OF USE OR BUSINESS REPUTATION OR OPPORTUNITY, LOSS OF DATA, FAILURE TO REALIZE SAVINGS OR BENEFITS, OR ANY DAMAGES BASED ON OR MEASURED BY ANY TYPE OF MULTIPLE, AND THE DEFINITION OF “ADVERSE CONSEQUENCES” IN SECTION 1.1 SHALL BE INTERPRETED TO EXCLUDE SUCH DAMAGES) ARISING UNDER THIS AGREEMENT OR THE ANCILLARY AGREEMENT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH LOSS.

Section 10.6 Tax Treatment of Indemnity Payments. Sellers and Buyer agree to treat any indemnity payment made pursuant to this Article X as an adjustment to the Purchase Price for Tax purposes. For the avoidance of doubt, all Taxes that would not have been imposed but for the Section 338(h)(10) Election, will be allocated to the Pre-Closing Tax Period.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in order that the Contemplated Transactions be consummated as originally contemplated to the greatest extent possible.

Section 11.14 Counterparts.

Delivery of an executed counterpart of a signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 11.15 Specific Enforcement. The Parties agree that immediate, extensive and irreparable damage would occur for which monetary damages would not be an adequate remedy in the event that any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached. Accordingly, the Parties agree that, if for any reason any Party shall have failed to perform its obligations under this Agreement or otherwise breached this Agreement, then the Party seeking to enforce this Agreement against such nonperforming Party under this Agreement shall be entitled to specific performance and the issuance of immediate injunctive and other equitable relief without the necessity of proving the inadequacy of money damages as a remedy, and the Parties further agree to waive any requirement for the securing or

69

posting of any bond in connection with the obtaining of any such injunctive or other equitable relief, this being in addition to and not in limitation of any other remedy to which they are entitled at Law or in equity. If any Party brings any Action to enforce specifically the performance of the terms and provisions of this Agreement when expressly available to such Party pursuant to the terms of this Agreement, then, notwithstanding anything to the contrary herein, the Termination Date shall automatically be extended by the period of time between the commencement of such Claim and ten (10) Business Days following the date on which such Claim is fully and finally resolved.

Section 11.16 Legal Representation. Buyer, on behalf of itself and its Affiliates, acknowledges and agrees that Sellers’ Counsel has acted as counsel for Sellers and their Affiliates, and that Sellers reasonably anticipate that Sellers’ Counsel will continue to represent Sellers and their Affiliates in future matters. Accordingly, Buyer, on behalf of itself and its Affiliates, expressly consents to: (a) Sellers’ Counsel representation of Sellers and their Affiliates, in any post-Closing matter in which the interests of Buyer, on the one hand, and Sellers or their respective Affiliates, on the other hand, are adverse, including any matter relating to the Contemplated Transactions or any disagreement or dispute relating thereto, and whether or not such matter is one in which Sellers’ Counsel may have previously advised Sellers or their Affiliates, and (b) the disclosure by Sellers’ Counsel to Sellers or their Affiliates, as applicable, of any information learned by Sellers’ Counsel in the course of its representation of Sellers or their Affiliates, as applicable, whether or not such information is subject to attorney-client privilege or Sellers’ Counsel’s duty of confidentiality. Furthermore, Buyer, on behalf of itself and its Affiliates, (1) irrevocably waives any right it may have to discover or obtain information or documentation relating to the representation of Sellers and its Affiliates by Sellers’ Counsel in the Contemplated Transactions, to the extent that such information or documentation was privileged as to Sellers or its Affiliates (“Confidential Communications”), and (2) agrees that (i) the privilege with respect to such Confidential Communications shall remain with Sellers following the Closing such that, without limiting Sellers’ rights to such privilege, Sellers alone shall have and maintain the right to waive the privilege, (ii) if Sellers’ former officers or managers leave any emails or other documents (both electronic or otherwise) that contain Confidential Communications on the servers of any Sale Entity or JV Company, such occurrence shall not constitute a waiver of the attorney-client privilege or any other privilege applicable to such documents, and (iii) to the extent any emails or other documents (either electronic or otherwise) containing any Confidential Communications are included in the computer server(s) of any Sale Entity or JV Company or are otherwise within the records of the Sale Entities and the JV Companies following the Closing, it will, upon discovery of any such documents, permanently delete or destroy all such emails or other documents containing such Confidential Communication and not review, disclose, or otherwise use such documents or the Confidential Communications for any purpose. Buyer, on behalf of itself and its Affiliates, further covenants and agrees that each shall not assert any claim against Sellers’ Counsel in respect of legal services provided to the Sale Entities or the JV Companies by Sellers’ Counsel in connection with this Agreement or the Contemplated Transactions. If and to the extent that, at any time subsequent to Closing, Buyer or any of its Affiliates shall have the right to assert or waive any attorney-client privilege with respect to any communication between Sellers or its Affiliates and any Person representing them that occurred at any time prior to the Closing, Buyer, on behalf of itself and its Affiliates, shall be entitled to waive such privilege only with the prior written consent of Sellers’ Counsel and Sellers.
