PURCHASE AND SALE OF INTERESTS

Section 2.1    Purchase and Sale of the Interests. Subject to the terms and conditions set forth in this Agreement:

(a)    Transfer of Interests. At the Closing and for the consideration specified in Section 2.1(b) below, Seller shall sell, convey, transfer, assign and deliver to Buyer, and Buyer shall purchase, acquire and accept from Seller all of the Interests.

(b)    Purchase Price.

(i)    The total consideration to be paid by Buyer for the Interests (the “Purchase Price”) shall be an amount equal to the sum of $1,290,000,000.00 (the “Base Purchase Price”) plus the Post-Closing Payment Amount (as determined and paid in accordance with Section 2.1(c) below). The Parties acknowledge and agree that all Indebtedness for borrowed money of the Sale Entities and the JV Company will remain outstanding at Closing except as set forth in Section 5.8(a). On November 2, 2020, Buyer shall pay, or cause to be paid, to Seller an amount equal to the Base Purchase Price by wire transfer of immediately available funds to one or more accounts designated by Seller.

(ii)    Notwithstanding anything to the contrary, (A) if this Agreement is terminated, or (B) for any other reason, the Closing has not occurred by December 30, 2021, Seller shall pay, or cause to be paid, to Buyer an amount equal to the Purchase Price Repayment Amount by wire transfer of immediately available funds to one or more accounts designated by Buyer no later than December 31, 2021. Within five (5) days of the consummation of any Alternative Transaction, Seller shall pay to Buyer the enterprise value of the capital stock, equity interests or assets sold by Seller or any of its Affiliates in such Alternative Transaction, disposition or sale (which, in the case of an asset sale, shall include a pro rata portion of any indebtedness that remains with Seller or its Affiliates participating in such asset sale following such asset sale), up to the remaining unpaid Purchase Price Repayment Amount. Notwithstanding anything to the contrary, at any time following the earlier of (i) a termination of this Agreement or (ii) July 1, 2021, but, in each case, prior to December 15, 2021, Seller shall be entitled to pay the remaining unpaid Purchase Price Repayment Amount in shares of DEI Common Stock (such portion of the remaining unpaid Purchase Price Repayment Amount paid in shares of DEI Common Stock, the “Stock Portion”)

16

by causing DEI to issue a number of shares of DEI Common Stock equal in value to the Stock Portion (based on the DEI Common Stock Closing Price and rounded to the nearest whole number of shares of DEI Common Stock) in electronic book-entry form to Buyer. For the avoidance of doubt, the payment of the Stock Portion in shares of DEI Common Stock shall reduce the amount of the Purchase Price Repayment Amount payable in immediately available funds on a dollar for dollar basis (based on the DEI Common Stock Closing Price). All of the shares of DEI Common Stock to be issued and delivered by DEI or Seller pursuant to this Agreement shall be (i) at the time of issuance, duly authorized, validly issued, fully paid and nonassessable and free and clear of any Liens, including those imposed by applicable securities laws and any stock exchange on which the shares of DEI Common Stock are listed, (ii) registered with the SEC for resale by Buyer within five (5) Business Days following the applicable Issuance Date, and (iii) upon registration with the SEC, listed on The New York Stock Exchange.

Upon registration of shares of DEI Common Stock issued pursuant to this Agreement, the Restrictive Legend will be removed on all of such shares of DEI Common Stock, and, in each case, DEI shall issue a certificate representing such shares of DEI Common Stock without such legend to Buyer or issue to Buyer by electronic delivery at the applicable balance account at The Depository Trust Company.

(c)    Post-Closing Payment Amount.

(i)    As promptly as practical, but in no event later than thirty (30) days after the Closing Date, Buyer shall (at Buyer’s expense) prepare and deliver to Seller a statement setting forth Buyer’s good faith calculation of the Preliminary Post-Closing Payment Amount, and documentation sufficient to confirm the accuracy of such calculation.

(ii)    Following Seller’s receipt of the Preliminary Post-Closing Payment Amount, Seller and their agents, representatives and advisors shall be permitted to review all books and records, working papers, financial records and information of Buyer related to the Preliminary Post-Closing Payment Amount and shall have such access to Buyer’s personnel as may be reasonably necessary to permit Seller to review in detail the manner in which the Preliminary Post-Closing Payment Amount was calculated and prepared. Within thirty (30) days after Seller’s receipt of the Preliminary Post-Closing Payment Amount, Seller shall either:

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 Seller, 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 Seller, 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), Seller 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

(B)    dispute such Preliminary Post-Closing Payment Amount, in which case (1) within ten (10) days of Seller’s notice to Buyer of such dispute, such dispute shall be referred to senior officers or other authorized representatives of Seller and Buyer or their respective Affiliates, for settlement of such dispute within thirty (30) days of referral, (2) the final amount agreed to by such senior officers or other authorized representatives shall be deemed final and shall be considered the “Post-Closing Payment Amount” for purposes of this Agreement and (3) (x) if the Post-Closing Payment Amount is positive, Buyer shall pay to Seller, 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 Seller, 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), Seller 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.

Section 2.2    Allocation.

(a)    On the Closing Date, Buyer shall prepare and deliver to Seller, 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 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, Seller 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 Seller 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 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 Seller of the Final Allocation Statement, Seller 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 Seller submits an Objections Notice on or before the expiration of such thirty (30) day period, the Final Allocation Statement prepared and delivered to Seller 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 Seller timely submits 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 Seller 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 Seller 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 Seller 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.

Section 2.3    Withholding. 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

19

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. Buyer shall use Reasonable Efforts to notify the Seller before making any such deduction or withholding.

To the extent required by applicable Tax Laws, Seller or any of its 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 Seller, which consent may be withheld in Seller’s sole discretion. The following provisions shall govern the allocation of responsibility as between the Parties for certain Tax matters following the Closing Date:

(i)    Seller 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, Seller 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. Seller shall reasonably consider any comments provided by Buyer.

Except as otherwise provided in this Section 5.3 (including, for the avoidance of doubt, Section 5.3(b)(iii)), Seller 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 Seller is not responsible pursuant to Section 5.3(a), and if Seller pays Taxes described in clause (A) or (B) on behalf of the Sale Entities or Buyer, the Sale Entities or Buyer shall reimburse Seller therefor within fifteen (15) days after the date on which the Taxes are paid. Notwithstanding any provision in this Agreement to the contrary, Seller 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 Seller Tax Returns pertaining to the Straddle Period for Seller’s 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. Seller shall review such Tax Returns within ten (10) days after the delivery of such Tax Returns. Seller 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 Seller delivers comments to Buyer within such ten (10) day review period, Buyer and Seller shall use good faith efforts to resolve any dispute in connection with such comments. In the event Buyer and Seller are unable to agree on any such revisions within ten (10) days after Seller provides its comments, Buyer and Seller 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 Seller’s 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.

(iii)    Seller 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, Seller 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)    Seller and Buyer agree that, except with respect to Tax incurred by Seller 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,

38

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 Seller or a Sale Entity on or before the Closing Date (whether through deposits, prepayments, credits, or otherwise), Buyer shall reimburse Seller 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 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 Seller is or may be liable for any Taxes pursuant to this Agreement, Buyer shall inform Seller 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 Seller with written notice of such Tax Proceeding, Seller’s 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 Seller, at Seller’s 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 Seller or any of its Affiliates. If Seller elects not to control the conduct of any such Tax Proceeding, Buyer shall control the conduct of such Tax Proceeding at Buyer’s expense, and Seller shall have the right (at Seller’s expense) to attend and participate in such Tax Proceeding. Neither Buyer nor Seller 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, Seller 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 Seller or any of its 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

39

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 Seller the difference within two (2) days of filing the relevant Tax Return that reflects such Tax.

(f)    Without duplication of amounts payable to Seller 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 Seller 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 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 Seller 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 Seller, which consent may be withheld in Seller’s 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 Seller’s (or any of its Affiliates) liability for Taxes (including any liability of Seller to indemnify Buyer for Taxes pursuant to this Agreement) or (B) result in, or change the character of, any income or gain that Seller (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 Seller or Seller’s Affiliates shall be terminated as of the Closing Date.

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

(i)    Seller 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”).

40

(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.

Section 5.4    Conduct of Business of the Sale Entities.

(a)    From the Effective Date until the earlier of the Closing and the termination of this Agreement pursuant to Article IX, Seller shall cause each of the Sale Entities and the JV Company (and with respect to the JV Company, solely to the extent that Seller or its Subsidiaries, pursuant to the JV Company’s Organizational Documents, are permitted to cause the JV Company), to (i) conduct its respective business in all material respects in the ordinary course of business, unless otherwise contemplated by this Agreement or with the prior written consent of Buyer (which consent shall not be unreasonably withheld, conditioned or delayed) and (ii) use its Reasonable Efforts to preserve and maintain its respective relationships with licensors, contractors, suppliers, dealers, customers, employees, Governmental Authorities and others having material business relationships with such Sale Entity or the JV Company.

Any actions of the Sale Entities or the JV Company 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 Seller 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.

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.

(b)    [Reserved.]

(c)    Commencing on the Closing Date and continuing through the date that is twenty four (24) months following the Closing Date (the “Continuation Period”), Buyer shall cause a Post-Closing Employer to provide to each Transferred Employee (i) base pay no less than his or her base pay in effect as of immediately prior to the Closing, (ii) a target annual cash bonus no less than his or her target annual cash bonus in effect as of immediately prior to the Closing; (iii) (1) an employer matching contribution rate under the Post-Closing Employer’s 401(k) plan that is no less than the employer matching contribution rate he or she would have received under the Dominion Energy Salaried Savings Plan as in effect immediately prior to the Closing, based on his or her years of service with both DEI and its Affiliates and Buyer and its Affiliates before and after the Closing, (2) defined-benefit pension benefits in accordance with Section 5.6(h) below, (3) retiree health and life insurance benefits in accordance with Section 5.6(i) below, and (4) other retirement and welfare benefits that are comparable, in the aggregate, to his or her retirement and welfare benefits in effect as of immediately prior to the Closing, and (iv) employment at a work location no more than fifty (50) miles from his or her work location as of immediately prior to the Closing. Buyer confirms its intent to maintain primary corporate offices for the Sale Entities with employees at or near their current locations (as set forth in Schedule 5.6(c)) during the Continuation Period.

(d)    DEI shall cause any long-term incentive award granted to a Company Employee under a DEI long-term incentive plan (a “DEI LTI Award”) to vest on a pro-

44

rata basis on the Closing Date in accordance with the terms of such plan, based on the period from the start of the vesting or performance period applicable to such award through the applicable Closing Date. With respect to each DEI LTI Award of a Transferred Employee that is pro-rated in accordance with the preceding sentence, Buyer shall cause the applicable Post-Closing Employer to grant to each such Transferred Employee a long-term incentive award under the Post-Closing Employer’s long-term incentive plan for the remainder of the original vesting or performance period applicable to such award, with a grant-date target value no less than the grant-date target value of the DEI LTI Award, pro-rated for such period. In addition, during the Continuation Period, Buyer shall cause the applicable Post-Closing Employer to continue to grant annual awards under its long-term incentive plan for eligible non-officer Transferred Employees on terms that are comparable to DEI’s Leadership Incentive Program as in effect as of the date hereof, and in annual amounts that, in the aggregate for all such Transferred Employees, are no less than the aggregate annual amounts most recently granted by DEI to such Transferred Employees under the Leadership Incentive Program prior to the Closing, with such grants occurring at the time annual long-term incentive grants are made generally by Buyer.

(e)    If, during the Continuation Period, (i) the employment of any Transferred Employee is involuntarily terminated, other than for cause, (ii) such Transferred Employee resigns by reason of his or her relocation, without his or her consent, to a work location that is more than fifty (50) miles from the individual’s work location immediately prior to the Closing, or (iii) such Transferred Employee resigns after being offered a position with base pay or target annual cash bonus that is less than that in effect immediately prior to Closing, Buyer shall cause the Post-Closing Employer to provide such Transferred Employee severance benefits that are no less than the severance benefits provided on Schedule 5.6(e).

(f)    During the Continuation Period, Buyer shall cause the Post-Closing Employer to provide to each Transferred Employee who was classified by DEI as an officer (Vice President or above) with: (i) annual grants (such grants occurring at the time annual long-term incentive grants are made generally by Buyer) of long-term incentive awards under the Post-Closing Employer’s long-term incentive plan on terms that are comparable to the terms of DEI’s long-term incentive program for officers as of the date hereof (the “DEI LTI Program”) and with target grant-date values of awards for each such eligible Transferred Employee that are no less than the target grant-date value of the most recent award received by the Transferred Employee under the DEI LTI Program prior to the Closing Date; (ii) executive perquisites (including leased vehicle, financial planning and health and wellness reimbursement) no less than his or her executive perquisites immediately prior to the Closing; (iii) continuation of premium payments under his or her universal life insurance policy in accordance with DEI’s program as in effect as of the date hereof; and (iv) supplemental retirement benefits that mirror DEI’s Benefit Restoration Plan as in effect as of the date hereof.

45

(g)    As of the Closing Date, all Transferred Employees shall, if applicable, be eligible to participate in and, if elected, shall commence participation in the employee benefit plans (within the meaning of Section 3(3) of ERISA), programs, policies, contracts, fringe benefits, or arrangements (whether written or unwritten), including, but not limited to, the tax-qualified defined benefit plan (“Post-Closing Salaried Pension Plan”), defined contribution plan, retiree medical plan and retiree life plan, of the applicable Post-Closing Employer or its Affiliate (collectively, “Post-Closing Employee Plans”). Buyer shall cause each Post-Closing Employer, to the extent permissible under any Post-Closing Employee Plan (provided that Buyer shall cause each Post-Closing Employer to use Reasonable Efforts to remove any restrictions including restrictions in any insurance policy), to waive all limitations as to pre-existing condition exclusions and waiting periods with respect to Transferred Employees and their spouses and dependents, if applicable, under the Post-Closing Employee Plans. Buyer shall cause each Post-Closing Employer, to the extent permissible under any Post-Closing Employee Plan (provided that Buyer shall cause each Post-Closing Employer to use its Reasonable Efforts to remove any restrictions under any Post-Closing Employee Plan or related insurance policy), to provide each Transferred Employee with credit for any co-payments and deductibles paid prior to the Closing Date in satisfying any deductible or out-of-pocket requirements under Post-Closing Employee Plans for the plan year in which the Closing Date occurs.

(h)    During the Continuation Period, Buyer shall cause each Post-Closing Employer to provide a Post-Closing Salaried Pension Plan that provides a level of pension benefits that is not lower than such level of pension benefits for the Transferred Employees as of the Closing Date using the applicable pension benefit formula provided in the Dominion Energy Pension Plan. Each Transferred 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 Employee under the Post-Closing Salaried Pension Plan, calculated as of such Transferred 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 Employee’s retirement or termination date; and (B) equals the accrued normal retirement benefit of such Transferred 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 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 Employee immediately prior to the Closing.

(k)    Buyer shall cause each Post-Closing Employer to accept or cause to be accepted transfers from DEI’s or any ERISA Affiliate’s flexible spending account plan of each Transferred Employee’s account balances as of the Closing Date and credit such employee with such amounts under the applicable Post-Closing Employee Plan.

(n)    To the extent allowable by law, Buyer shall take any and all necessary action to cause the trustee of a defined contribution plan of Buyer or one of its Affiliates, if requested to do so by a Transferred Employee, to accept a direct “rollover” of all or a portion of such employee’s distribution from a defined contribution plan maintained by DEI or any ERISA Affiliate (excluding securities, but including plan loans) if such Transferred Employee elects such direct rollover within sixty (60) days following the Closing Date.

(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.

(p)    With respect to each Company Employee (including any beneficiary or the dependent thereof), DEI or each ERISA Affiliate shall retain all liabilities and obligations arising under any medical, dental, vision, life insurance or accident insurance benefit plans sponsored by DEI or such ERISA Affiliate to the extent that such liability or obligation relates to claims incurred (whether or not reported or paid) prior to the Closing Date. For purposes of this Section 5.6(p), a claim shall be deemed to be incurred (i) with

47

respect to medical, dental and vision benefits, on the date that the medical, dental or vision services giving rise to such claim are performed, (ii) with respect to life insurance, on the date that the death occurs, and (iii) with respect to accidental death and dismemberment and business travel accident insurance, on the date that the accident occurs.

(q)    With respect to each Company Employee who is not actively at work and who is, as of the Closing Date, receiving any form of pay/wage continuation (including, but not limited to, short-term sickness, disability, military leave or vacation pay), DEI or each ERISA Affiliate shall be responsible for any such payments due prior to the Closing Date and Buyer or the applicable Post-Closing Employer shall be responsible for any payments due on or after the Closing Date, except as provided in Section 5.6(r) with respect to workers’ compensation benefits.

(r)    DEI and its Affiliates shall be responsible for all workers’ compensation liabilities and obligations for Company Employees or other former employees of the Sale Entities to the extent such liabilities and obligations relate to events which occurred prior to the Closing.

(t)    If a plant closing or a mass layoff occurs or is deemed to occur with respect to a Sale Entity at any time on or after the Closing Date, Buyer shall be solely responsible for providing all notices required under the Worker Adjustment and Retraining Notification Act, 29 U.S.C. §2109 et seq. or the regulations promulgated thereunder or similar state laws and for taking all remedial measures, including, without limitation, the payment of all amounts, penalties, liabilities, costs and expenses if such notices are not provided.

(u)    DEI or its Affiliate shall pay to each eligible Company Employee a prorated payment in accordance with the DEI’s annual cash incentive plan for the period from January 1 through the Closing Date for the year in which the Closing occurs based on actual results of the applicable performance goals for that year. Buyer shall cause the applicable Post-Closing Employer to pay to each eligible Transferred Employee a prorated payment under the Post-Closing Employer’s annual incentive plan for the period from the Closing Date through December 31 of the year in which the Closing occurs.

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.

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 11.15    Specific Enforcement.

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 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

67

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 Seller’s Counsel has acted as counsel for Seller and its Affiliates, and that Seller reasonably anticipate that Seller’s Counsel will continue to represent Seller and its Affiliates in future matters. Accordingly, Buyer, on behalf of itself and its Affiliates, expressly consents to: (a) Seller’s Counsel representation of Seller and its Affiliates, in any post-Closing matter in which the interests of Buyer, on the one hand, and Seller or its 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 Seller’s Counsel may have previously advised Seller or its Affiliates, and (b) the disclosure by Seller’s Counsel to Seller or its Affiliates, as applicable, of any information learned by Seller’s Counsel in the course of its representation of Seller or its Affiliates, as applicable, whether or not such information is subject to attorney-client privilege or Seller’s 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 Seller and its Affiliates by Seller’s Counsel in the Contemplated Transactions, to the extent that such information or documentation was privileged as to Seller or its Affiliates (“Confidential Communications”), and (2) agrees that (i) the privilege with respect to such Confidential Communications shall remain with Seller following the Closing such that, without limiting Seller’s rights to such privilege, Seller alone shall have and maintain the right to waive the privilege, (ii) if Seller’s 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 the 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 the JV Company or are otherwise within the records of the Sale Entities and the JV Company 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 Seller’s Counsel in respect of legal services provided to the Sale Entities or the JV Company by Seller’s 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 Seller 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 Seller’s Counsel and Seller.

Section 11.17    Guarantee. Guarantor hereby unconditionally guarantees, as a primary obligor and not merely as a surety, the obligations of Seller set forth in Sections 2.1(b) and 9.2 (such obligations, the “Seller Guaranteed Obligations”). The Seller Guaranteed Obligations are

68

primary, absolute, unconditional and irrevocable. Guarantor acknowledges and agrees that its obligations hereunder shall continue in full force and effect, without notice from any other party in the event the obligations of Seller or Guarantor under this Agreement are amended or in any way modified, and that the Seller Guaranteed Obligations shall continue and shall apply in full to such amended obligations of Seller or Guarantor as though the amended terms had been part of this Agreement from the original date of execution thereof. Guarantor represents and warrants to Buyer that (i) it is duly organized, validly existing and in good standing under the Laws of Virginia, and has the requisite corporate power and authority to own or lease its assets and to conduct its business in all material respects as it is now being conducted, (ii) the execution, delivery and performance by Guarantor of this Agreement and the consummation of the transactions contemplated hereby are within the corporate powers of Guarantor and (iii) this Agreement has been duly and validly executed and delivered by Guarantor and (assuming the due and valid execution and delivery of this Agreement by Seller) constitutes a legal, valid and binding agreement of Guarantor, enforceable against Guarantor in accordance with its terms, except as enforcement may be limited by the Bankruptcy and Equity Exception.
