(iii) The limited liability company interests in Merger Sub issued and outstanding immediately prior to the Company Merger Effective Time shall remain issued and outstanding as the limited liability company interests of the Surviving Company. Such limited liability company interests shall be the only interests in the Surviving Company that are issued and outstanding immediately after the Company Merger Effective Time.

Section 2.2Treatment ofEquity Awards and Plans.

(a)LTIP Units. Immediately prior to the Company Merger Effective Time, (i) any vesting conditions applicable to each outstanding LTIP Unit (as defined in the Company’s 2015 Equity Incentive Plan (the “Stock Plan”)), shall, as provided in Section 4.4(E)(vi) of the Partnership Agreement, automatically and without any required action on the part of the holder thereof, accelerate in full, and all restrictions with respect thereto shall, automatically and without any required action on the part of the holder thereof, lapse and (ii) the Company, as the general partner of the Partnership, shall exercise its right to cause a Forced Conversion (as defined in the Partnership Agreement) with respect to the maximum number of LTIP Units then eligible for conversion in accordance with Section 4.4.E(iii) of the Partnership Agreement, such that, as of immediately prior to the Company Merger Effective Time, each LTIP Unit shall be converted into one Partnership Unit. For the avoidance of doubt, such Partnership Units issued in respect of such LTIP Units shall be treated as Partnership Units for purposes of this Agreement and the holders of such Partnership Units shall be treated as holders of Partnership Units as described inSection 2.1(b).

(b)ESPP. As soon as reasonably practicable following the date of this Agreement and in any event prior to the Company Merger Effective Time, the Company shall take all actions (including obtaining any necessary determinations and/or resolutions of the Company Board or a committee thereof and, if appropriate, amending the terms of the Company’s 2015Non-Qualified Employee Stock Purchase Plan (the “ESPP”)) that may be necessary or required under the ESPP and applicable Law to (i) ensure that no purchase period shall be authorized or commenced under the ESPP on or after the date of this Agreement, (ii) terminate the ESPP in its entirety at the Company Merger Effective Time with no further rights granted or exercised under the ESPP thereafter and (iii) prohibit the entry of new participants in the ESPP following the date of this Agreement.

The Company shall take all actions necessary to ensure that from and after the Company Merger Effective Time neither Parent nor the Surviving Company will be required to deliver Company Shares, Partnership Units or other capital stock of the Company or the Partnership to any Person pursuant to or in settlement of Company equity awards.

Section 2.3Exchange and Payment.

(a) Prior to the Closing, Parent, Merger Sub and Merger Partnership shall enter into an agreement (in a form reasonably acceptable to the Company and the Partnership) with Equiniti Trust Company to act as agent for the equityholders of the Company and the Partnership in connection with the Mergers (the “Paying Agent”) to receive the applicable Merger Consideration to which holders of Company Shares or Partnership Units shall become entitled pursuant to thisArticle II. At or prior to the Closing, Parent shall deposit (or cause to be deposited) with the Paying Agent cash in an amount sufficient to make all payments pursuant to thisArticle II (such cash being hereinafter referred to as the “Payment Fund”). The Paying Agent shall make payments of the Company Merger Consideration and the Partnership Merger Consideration out of the Payment Fund in accordance with this Agreement. The Payment Fund shall not be used for any purpose other than to fund payments due pursuant to thisArticle II, except as provided in this Agreement. The Surviving Company shall pay all charges and expenses, including those of the Paying Agent, incurred by it in connection with the exchange of Company Shares and Partnership Units for the applicable Merger Consideration.

(b) Promptly after the Closing, the Surviving Company shall cause the Paying Agent to mail to each holder of record of a certificate or certificates that (i) immediately prior to the Company Merger Effective Time represented outstanding Company Shares (each, a “Share Certificate”) that were converted into the right to receive the Per Share Merger Consideration with respect thereto pursuant toSection 2.1(a)(i) and (ii) immediately prior to the Partnership Merger Effective Time represented outstanding Partnership Units (together with the Share Certificates, the “Certificates”) that were converted into the right to receive the Per Partnership Unit Merger Consideration with respect thereto pursuant toSection 2.1(b)(i): (A) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such Person shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof as provided inSection 2.3(i)) to the Paying Agent); and (B) instructions for use in effecting the surrender of such Certificates (or affidavits of loss in lieu thereof as provided inSection 2.3(i)) in exchange for the applicable Merger Consideration payable with respect thereto pursuant toSection 2.1(a)(i) andSection 2.1(b)(i). Upon surrender of a Certificate (or an affidavit of loss in lieu thereof as provided inSection 2.3(i)) to the Paying Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be reasonably required, the holder of such Certificate shall be entitled to receive in exchange therefor the applicable Merger Consideration for each Company Share or Partnership Unit, as applicable, formerly represented by such Certificate (subject to deduction for any required withholding Tax), and the Certificate so surrendered shall forthwith be canceled. Promptly after the Closing Date, the Paying Agent shall issue and deliver to each holder of uncertificated Company Shares or Partnership Units represented by book entry (“Book-Entry Interests”) a check or wire transfer for the amount of cash that such holder is entitled to receive pursuant toSection 2.1(a)(i) andSection 2.1(b)(i) in respect of such

Book-Entry Interests, without such holder being required to deliver a Certificate or an executed letter of transmittal to the Paying Agent, and such Book-Entry Interests shall then be canceled. No interest will be paid or accrued for the benefit of holders of Certificates or Book-Entry Interests on the applicable Merger Consideration payable in respect of Certificates or Book-Entry Interests.

(c) If payment of the applicable Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Interest is registered, it shall be a condition of payment that such Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer or such Book-Entry Interest shall be properly transferred and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the applicable Merger Consideration to a Person other than the registered holder of the Certificate or Book-Entry Interest surrendered or shall have established to the satisfaction of the Surviving Company or the Partnership, as applicable, that such Tax either has been paid or is not applicable.

(d) Until surrendered or transferred as contemplated by thisSection 2.3, each Certificate or Book-Entry Interest (other than any Certificate or Book-Entry Interest evidencing Company Shares to be canceled in accordance withSection 2.1(a)(ii)) shall be deemed at any time after the Company Merger Effective Time or the Partnership Merger Effective Time, as applicable, to represent only the right to receive the applicable Merger Consideration payable in respect of Company Shares or Partnership Units theretofore represented by such Certificate or Book-Entry Interests, as applicable, pursuant toSection 2.1(a)(i) andSection 2.1(b)(i).

(e) Prior to the Closing, Parent and the Company shall cooperate to establish procedures with the Paying Agent and the Depository Trust Company (“DTC”) to ensure that (i) if the Closing occurs at or prior to 10:30 a.m. (Dallas time) on the Closing Date, the Paying Agent will transmit to DTC or its nominees on the Closing Date an amount in cash in immediately available funds equal to the number of Company Shares held of record by DTC or such nominee immediately prior to the Company Merger Effective Time multiplied by the Per Share Merger Consideration (such amount, the “DTC Payment”) and (ii) if the Closing occurs after 10:30 a.m. (Dallas time) on the Closing Date, the Paying Agent will transmit to DTC or its nominee on the first Business Day after the Closing Date an amount in cash in immediately available funds equal to the DTC Payment.

All cash paid upon the surrender for exchange of Certificates or Book-Entry Interests in accordance with the terms of thisArticle II shall be deemed to have been paid in full satisfaction of all rights pertaining to the Company Shares or Partnership Units, as applicable, formerly represented by such Certificates or Book-Entry Interests. On the Closing Date, the stock transfer books of the Company and the unit transfer books of the Partnership shall be closed and there shall be no further registration of transfers of the Company Shares or Partnership Units (except for the transfer of Partnership Units owned by the Company to the Surviving Company in the Company Merger and

the transfer of Partnership Units to Parent Affiliate in the Affiliate Contribution). If, after the Closing, Certificates are presented to the Surviving Company, the Surviving Partnership or the Paying Agent for transfer or transfer is sought for Book-Entry Interests, such Certificates or Book-Entry Interests shall be canceled and exchanged as provided in thisArticle II.

(g) The Paying Agent shall invest any cash included in the Payment Fund as directed by the Surviving Company, on a daily basis;provided, that any investment of such cash shall in all events be in short-term obligations of the United States of America with maturities of no more than 30 days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America or in commercial paper obligations ratedA-1 orP-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively. If for any reason (including investment losses) the cash in the Payment Fund is insufficient to fully satisfy all of the payment obligations to be made in cash by the Paying Agent hereunder (but subject toSection 2.4), the Surviving Company shall promptly deposit cash into the Payment Fund in an amount which is equal to the deficiency in the amount of cash required to fully satisfy such cash payment obligations. Any interest and other income resulting from such investments shall be payable to the Surviving Company.

(h) At any time following the date that is 12 months after the Closing Date, the Surviving Company shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) which have been made available to the Paying Agent and which have not been disbursed to holders of Certificates or Book-Entry Interests, and thereafter such holders shall be entitled to look to the Surviving Company or the Surviving Partnership (subject to abandoned property, escheat or other similar Laws), as applicable, only as general creditors thereof with respect to the applicable Merger Consideration payable upon due surrender of their Certificate or Book-Entry Interests.

(i) If any Certificates have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and the holder’s compliance with the replacement requirements established by the Paying Agent, including, if necessary, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against such Certificates, the Surviving Company or the Surviving Partnership with respect to such Certificate, the Paying Agent will deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration payable in respect thereof pursuant to this Agreement.

(j) None of Parent, Merger Sub, the Surviving Company, the Partnership, Merger Partnership, the Surviving Partnership, the Company or the Paying Agent, or any employee, officer, trustee, director, agent or Affiliate thereof, shall be liable to any Person in respect of Merger Consideration from the Payment Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any amounts remaining unclaimed by holders of Certificates or Book-Entry Interests immediately prior to the time at which such amounts would otherwise escheat to, or become the property of, any Governmental Entity shall, to the extent permitted by applicable Law, become the property of the Surviving Company, free and clear of any claims or interest of any such holders or their successors, and any former holder of Company Shares or Partnership Units who has not theretofore complied with thisSection 2.3 shall thereafter look only to the Surviving Company for payment of their claim for applicable Merger Consideration, without any interest thereon.

Section 2.4Withholding Rights. Each Person making any payment pursuant to this Agreement or the transactions contemplated hereby shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Company Shares or Partnership Units or any amounts otherwise payable pursuant to this Agreement or the transactions contemplated hereby, as applicable, such amounts as such payor is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld and paid over to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement and the transactions contemplated hereby, as applicable, as having been paid to the Person in respect of which such deduction and withholding was made.

(b)No Solicitation or Negotiation. Except as otherwise expressly provided by thisSection 5.4 and subject toSection 5.4(d) andSection 5.4(g), the Company agrees that, from theGo-Shop Period End Time until the earlier of the Company Merger Effective Time and the termination of this Agreement in accordance withArticle VII, and subject to the other provisions of thisSection 5.4, neither the Company, any of the Company Subsidiaries, nor any of their respective directors, officers or employees, shall, and the Company shall cause its and the Company Subsidiaries’ other Representatives not to, directly or indirectly:

(iii) waive, terminate, modify, amend, release or assign any provisions of any confidentiality or standstill agreement (or similar agreement) to which it is a party or fail to enforce, to the fullest extent permitted under applicable Law, the provisions of any such agreement, including by obtaining an injunction to prevent any breach of such agreements and to enforce specifically the terms and provisions thereof in any court having jurisdiction;

(v) agree to or propose publicly to do any of the foregoing.

Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any of the Company or any Company Subsidiary or their respective Representatives shall be deemed to be a breach of thisSection 5.4 by the Company.

None of the Company or any Company Subsidiary shall, after the date of this Agreement, enter into any confidentiality or similar agreement that would prohibit it from providing the information set forth in thisSection 5.4(d) to Parent.

(e)Definitions. As used in this Agreement:

(i) “Acquisition Proposal” means any indication of interest, proposal, offer or inquiry, written or oral (whether binding ornon-binding), made by any Person or group of Persons (other than Parent, Merger Sub and Merger Partnership) with respect to (A) any merger, joint venture, partnership, consolidation, dissolution, liquidation, tender offer, recapitalization, reorganization, share exchange, business combination, restructuring, refinancing or other similar transaction (whether or not subject to anypre-conditions), or any revisions thereof, involving the Company (or any Company Subsidiary), (B) any acquisition by any Person, which, if consummated would result in, any Person (or group of Persons) becoming the beneficial owner or having the right to acquire beneficial ownership, directly or indirectly, in one transaction or a series of related transactions, of 20% or more of the total voting power or any class of the equity securities of the Company, (C) any direct or indirect acquisition, purchase, lease, exchange, transfer or license, in a single transaction or a series of related transactions, including by means of the acquisition of shares of any Company Subsidiary, which if consummated would result in any Person or group of Persons becoming the owner of assets or properties that constitute 20% or more of the assets and properties (based on fair market value) of the Company and the Company Subsidiaries, taken as a whole, immediately prior to such transaction, (D) any issuance or sale or other disposition (including by way of merger, consolidation, share exchange, business combination, reorganization, recapitalization or other similar transaction) in a single transaction or a series of related transactions of 20% or more of the voting power of any class of equity securities of the Company or 20% or more of the equity interests or general partner interests in the Partnership or (E) any other transaction having a similar effect to those described in the foregoingclauses (A) through(D), in each case, other than the transactions contemplated by this Agreement.

(ii) “Excluded Party” means any Person or group of Persons from whom the Company or any of its Representatives has received a written Acquisition Proposal after the execution of this Agreement and prior to theGo-Shop Period End Time that the Company Board has determined in good faith, after consultation with its financial advisor and outside legal counsel, either constitutes a Superior Proposal or is reasonably likely to lead to a Superior Proposal (such determination to be made no later than theGo-Shop Period End Time);provided, that any such Person or group shall cease to be an Excluded Party upon the earliest to occur of the following: (A) in the case of a group of Persons, the members of such group that were members of such group immediately prior to theGo-Shop Period End Time no longer constitute, or would no longer be reasonably capable of constituting, more than 50% of the equity financing of such group of Persons at all times following theGo-Shop Period End Time; (B) such Person’s or group’s Acquisition Proposal is withdrawn, terminated or expires (it being understood that any amendment, modification or replacement of such Acquisition Proposal shall not, in and of itself, be deemed a withdrawal of such Acquisition Proposal); (C) the Company Board determines in good faith, after consultation with its financial advisor and outside legal counsel, that such Person’s or group’s Acquisition Proposal no longer constitutes a Superior Proposal or is no longer reasonably likely to lead to a Superior Proposal; and (D) 11:59 p.m. (Dallas time) on the 70^th day following the date hereof.

(iii) “Superior Proposal” means any unsolicited (unless made by an Excluded Party)bona fidewritten Acquisition Proposal (except that, for purposes of this definition, the references in the definition of “Acquisition Proposal” to “20%” shall be replaced by “50%”) which the Company Board has determined in its good faith judgment,

after consultation with outside legal counsel and financial advisors, taking into account all legal, financial and regulatory aspects of the transaction described in such Acquisition Proposal, including the identity of the Person making such Acquisition Proposal, the certainty of closing, the availability of financing and the ability of such Person to consummate the transactions contemplated by the Acquisition Proposal, (A) would reasonably be expected to be consummated in accordance with its terms (if accepted) and (B) is on terms and conditions more favorable to the holders of Company Shares (solely in their capacities as such) from a financial point of view than the transactions contemplated by this Agreement (after taking into account any revisions to the terms of the transactions contemplated bySection 5.4(g) and any different time period likely to be required to consummate such Acquisition Proposal relative to the transactions contemplated by this Agreement).

(f)No Adverse Recommendation Change or Alternative Acquisition Agreement. Except as expressly permitted bySection 5.4(g), the Company Board (or any committee thereof) shall not:

(i) (A) withhold, withdraw or fail to make when required by this Agreement (or publicly propose or resolve to withhold, withdraw or fail to make when required by this Agreement) the Company Recommendation, (B) qualify, amend or modify (or publicly propose or resolve to qualify, amend or modify), in a manner adverse to Parent or Merger Sub, the Company Recommendation, (C) fail to include the Company Recommendation in the Proxy Statement, (D) approve, endorse, adopt or recommend (or propose to approve, endorse, adopt or recommend) an Acquisition Proposal, (E) if any Acquisition Proposal that is structured as a tender offer or exchange offer for outstanding Company Shares is commenced pursuant to Rule14d-2 of the Exchange Act, make any public recommendation other than a recommendation in a Solicitation/Recommendation Statement on Schedule14D-9 against such Acquisition Proposal, (F) if an Acquisition Proposal other than an Acquisition Proposal subject to Regulation 14D shall have been publicly announced or disclosed, fail to recommend against such Acquisition Proposal or fail to reaffirm the Company Recommendation on or prior to the earlier of (1) the date that is five Business Days prior to the Company Stockholders Meeting and (2) 10 Business Days (which for this purpose shall be used as such term is used in Rule14d-9 of the Exchange Act) after such Acquisition Proposal shall have been publicly announced or disclosed (or such fewer number of days as remains prior to the Company Stockholders Meeting), or (G) resolve or agree to do any of the foregoing (any of the actions described in the foregoingclauses (A) through(F), an “Adverse Recommendation Change”); or

(ii) approve, adopt, publicly declare advisable or recommend (or agree to, resolve or publicly propose to approve, adopt, declare advisable or recommend), or cause or permit the Company to enter into any Alternative Acquisition Agreement (other than an Acceptable Confidentiality Agreement).

(g)Adverse Recommendation Change. Notwithstanding anything to the contrary in this Agreement, at any time prior to the time, but not after, the Company Stockholder Approval is obtained, the Company Board may (i) following receipt of abona fide Acquisition Proposal after the execution of this Agreement that did not result from a material breach of this

Section 5.4 and that the Company Board determines in good faith (after consultation with its financial advisor and outside legal counsel) constitutes a Superior Proposal, if such Acquisition Proposal has not been withdrawn and continues to be a Superior Proposal, (A) make an Adverse Recommendation Change or (B) terminate this Agreement pursuant toSection 7.1(c)(ii) and concurrently enter into an Alternative Acquisition Agreement with respect to such Superior Proposal, or (ii) in response to a material event, occurrence, development or state of facts or circumstances that was not known to the Company Board prior to the date of this Agreement (or if known, the consequences of which were not known or reasonably foreseeable), other than the receipt, existence or terms of an Acquisition Proposal, or an inquiry, proposal or offer that constitutes or could reasonably be expected to lead to an Acquisition Proposal, or the consequences thereof (an “Intervening Event”), make an Adverse Recommendation Change, in each case referred to in the foregoingclauses (i) and(ii), only if the Company Board determines in good faith, after consultation with outside legal counsel, that failure to take such action would be inconsistent with the directors’ duties under applicable Law;provided,however, that the Company Board shall not be entitled to effect an Adverse Recommendation Change under thisSection 5.4(g) or terminate this Agreement pursuant toSection 7.1(c)(ii) unless:

(i) the Company shall have provided prior written notice (a “Determination Notice”) to Parent at least five Business Days in advance of taking such actions (the “Notice Period”) to the effect that the Company Board intends to take such action and specifying in reasonable detail the circumstances giving rise to such proposed action, including, in the case such action is proposed to be taken in connection with a Superior Proposal, the information specified bySection 5.4(d) with respect to such Superior Proposal, including describing the material terms and conditions of, and attaching an unredacted copy of the most recent draft of, the Superior Proposal that is the basis of such action and the material terms of any financing commitment related thereto (it being understood that such material terms shall include the identity of the Person making such Superior Proposal), and, in the case such action is proposed to be taken in connection with an Intervening Event, the material facts underlying the Company Board’s determination that an Intervening Event has occurred;

(ii) the Company shall have, and shall have caused its financial and legal advisors to have, during the Notice Period, negotiated with Parent and its Representatives in good faith (to the extent Parent desires to negotiate) to make such adjustments to the terms and conditions of this Agreement such that it would cause such Acquisition Proposal to no longer constitute a Superior Proposal (or, in the case of an Adverse Recommendation Change in response to an Intervening Event, such that the failure to effect an Adverse Recommendation Change would not be inconsistent with the directors’ duties under applicable Law);provided,however, that in the event of any amendment to the financial terms or any other material terms of such Superior Proposal or any material change in the facts or circumstances relating to an Intervening Event, the Company shall be required to deliver a new Determination Notice to Parent and to comply with the requirements of thisSection 5.4(g)(ii) with respect to such new Determination Notice and a new Notice Period (with such Notice Period and each subsequent Notice Period having a term of two Business Days) shall commence upon the delivery of such new Determination Notice; and

(iii) at or following the end of such Notice Period, the Company Board, after taking into account any revisions to this Agreement made or proposed in writing by Parent prior to the time of such determination pursuant toSection 5.4(g)(ii), shall have determined in good faith, after consultation with its financial advisor and outside legal counsel, that in the case of a Superior Proposal, the Acquisition Proposal continues to constitute a Superior Proposal (or, in the case of an Adverse Recommendation Change in response to an Intervening Event, that the failure to effect an Adverse Recommendation Change would still be inconsistent with the directors’ duties under applicable Law), taking into account any changes to this Agreement proposed in writing by Parent in response to the Determination Notice or otherwise.

(h)Certain Permitted Disclosure. Nothing contained in thisSection 5.4 shall be deemed to prohibit the Company, the Company Board or any committee of the Company Board from (i) taking and disclosing to the stockholders of the Company a position contemplated byRule 14e-2(a),Rule 14d-9 or Item 1012(a) ofRegulation M-A promulgated under the Exchange Act, (ii) making a“stop-look-and listen” communication to the Company stockholders pursuant toRule 14d-9(f) promulgated under the Exchange Act (or any similar communications to the Company stockholders) and (iii) making any other disclosure to the stockholders if the Company Board determines in good faith, after consultation with outside legal counsel, that failure to make such disclosure would be inconsistent with the directors’ duties under applicable Law;provided that any Adverse Recommendation Change may only be made in accordance withSection 5.4(g).

(i)No-Shop Period. From and after theGo-Shop Period End Time, except as otherwise provided inSection 5.4(a), the Company, the Company Subsidiaries and each of their respective officers and directors will, and the Company will cause its, its Affiliates’ and the Company Subsidiaries’ employees and other Representatives to, immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Person conducted heretofore with respect to any Acquisition Proposal. The Company also agrees that it will promptly (and, in any event, within 24 hours of theGo-Shop Period End Time or, with respect to each Excluded Party, once such Person ceases to be an Excluded Party) request the prompt return or destruction of allnon-public information concerning the Company or its Subsidiaries theretofore furnished by the Company or any Company Subsidiary or their respective Representatives to any such Person with whom a confidentiality agreement related to a strategic transaction was entered into at any time in accordance with the terms of such confidentiality agreement and shall cease providing any further information to any such Person or its Representatives and it will immediately terminate all access granted to any such Person and its Representatives to any physical or electronic data room. The Company agrees that it will promptly inform its Representatives of the obligations undertaken in thisSection 5.4(i).

Section 5.5Preparation of Proxy Statement; Stockholders’ Meeting.

(a) As promptly as reasonably practicable following the submission of the PUCT Filing (but in any event, no more than 10 days after the date on which the PUCT Filing is submitted), the Company shall, with the assistance of Parent, prepare and file the Proxy Statement in preliminary form relating to the Company Stockholders Meeting and, subject toSection 5.4(g), shall include the Company Recommendation in the Proxy Statement.

(b) Parent, Merger Sub, Merger Partnership, the Company and the Partnership shall cooperate with each other in the preparation of the Proxy Statement. Without limiting the generality of the foregoing, each of Parent, Merger Sub and Merger Partnership will furnish to the Company the information relating to it required by the Exchange Act and the rules and regulations promulgated thereunder to be set forth in the Proxy Statement. Each of Parent, Merger Sub, Merger Partnership, the Company and the Partnership shall promptly correct any information provided by it for use in the Proxy Statement which shall have become false or misleading. In furtherance of the foregoing, the Company shall, upon written request, provide legal counsel to Parent with a reasonable opportunity to review and comment on the Proxy Statement, all responses to requests for additional information by, and replies to comments of, the SEC, prior to filing such documents with the applicable Governmental Entity and mailing such documents to the Company’s stockholders. The Company shall consider in good faith all comments reasonably proposed by Parent or its legal counsel and agrees that all information relating to Parent and its Subsidiaries included in the Proxy Statement shall be in the form and content reasonably satisfactory to Parent. The Company shall as soon as reasonably practicable notify Parent of the receipt of any comments from the SEC with respect to the Proxy Statement and any request by the SEC for any amendment to the Proxy Statement or for additional information. The Company shall use its commercially reasonable efforts to resolve all SEC comments with respect to the Proxy Statement as promptly as practicable after receipt thereof, and the Company shall cause the definitive Proxy Statement to be mailed to the Company’s stockholders as promptly as reasonably practicable after the date the SEC staff advises that it has no further comments thereon.

(c) As promptly as reasonably practicable (but no more than 40 days after the date on which the Proxy Statement is mailed to the Company’s stockholders), the Company, acting through the Company Board, shall (i) take all action necessary in accordance with applicable Law, the Company Charter and the Company Bylaws to duly call, give notice of, convene and hold a meeting of its stockholders for the purpose of obtaining the Company Stockholder Approval (the “Company Stockholders Meeting”) and (ii) except to the extent that the Company Board shall have effected an Adverse Recommendation Change in accordance withSection 5.4(g), include in the Proxy Statement the recommendation of the Company Board that the stockholders of the Company vote in favor of the approval of this Agreement and use its reasonable best efforts to solicit the Company Stockholder Approval (including by soliciting proxies from the Company’s stockholders). Unless the Company Board shall have effected an Adverse Recommendation Change as permitted by and determined in accordance withSection 5.4(g), the parties shall cooperate and use their reasonable best efforts to defend against any efforts by any Person, which could reasonably be expected to prevent the Company Stockholder Approval from being obtained;provided,however, that any indication by one or more stockholders of the Company of its or their intent to vote against the adoption of this Agreement and the approval of the Company Merger will not, in and of itself, give rise to any such obligation of the Company. The Company shall not postpone or adjourn the Company Stockholders Meeting;provided,however, that (x) the Company may adjourn, recess, or postpone, and at the request of Parent it shall adjourn, recess or postpone, the Company Stockholders Meeting for a reasonable period to solicit additional proxies, if the Company or Parent, respectively, reasonably believes there will be insufficient Company Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Company Stockholders Meeting or to obtain the Company Stockholder Approval (providedthat, unless agreed in writing by the Company and Parent, all such adjournments, recesses or postponements shall be for no more than 10 Business Days each) and (y) the Company may

adjourn, recess, or postpone the Company Stockholders Meeting to the extent (and only to the extent) that the Company Board determines in good faith, after consultation with the Company’s outside legal counsel and Parent, that such adjournment, recess or postponement is necessary under applicable Law for the filing and distribution of any amended or supplemental disclosure. Upon written request, the Company shall keep Parent reasonably informed regarding the status of the proxy solicitation, including, if requested, by promptly providing daily voting reports. The Company shall use its reasonable best efforts to ensure that the Company Stockholders Meeting is called, noticed, convened, held and conducted, and that all proxies solicited in connection with the Company Stockholders Meeting are solicited in compliance with applicable Law, the rules of the NYSE and the Company Charter and the Company Bylaws. The Company agrees that, unless this Agreement shall have been validly terminated in accordance withArticle VII, the obligation of the Company to call, give notice of, convene and hold the Company Stockholders Meeting and mail the Proxy Statement to the Company’s stockholders shall not be affected by an Adverse Recommendation Change or the commencement, public proposal, public disclosure or communication to the Company, the Company Board or any committee thereof of any Acquisition Proposal. The Company agrees that no matters shall be brought before the Company Stockholders Meeting other than the adoption of this Agreement and approval of the Company Merger and the other transactions contemplated by this Agreement, any related “golden parachute” vote under Rule14a-21(c) of the Exchange Act and any related and customary procedural matters (including a proposal to adjourn the meeting to allow additional solicitation of votes).

(a) From the date hereof to the Partnership Merger Effective Time or the earlier termination of this Agreement, upon reasonable prior written notice, and subject toSection 5.7(b)(viii), the Company shall, and shall cause the Company Subsidiaries (including, for the avoidance of doubt, the Partnership) and/or Hunt Manager to, afford to Parent and its Representatives reasonable access during normal business hours, consistent with applicable Law, to all their respective properties, facilities, personnel, contracts and books and records, including to conductnon-invasive environmental site assessments, and shall furnish Parent with all financial, operating and other data and information as Parent shall reasonably request in writing.Notwithstanding the foregoing, any such investigation or consultation shall be conducted in such a manner as not to interfere unreasonably with the business or operations of the Company or the Company Subsidiaries. None of the Company, any of the Company Subsidiaries or Hunt Manager shall be required to provide access to or to disclose information where such access or disclosure would (i) breach any agreement with any third party, (ii) constitute a waiver of or jeopardize the attorney-client or other privilege held by the Company or (iii) otherwise violate any applicable Law (provided that the Company shall use reasonable best efforts to allow for such access or disclosure in a manner that does not result in such a loss, breach or violation of such privilege).

(b) Except as otherwise expressly permitted or contemplated by this Agreement, each party shall continue to abide by the terms of the Amended and Restated Confidentiality Agreement, dated June 18, 2018, by and between the Company and Parent (the “ConfidentialityAgreement”), which Confidentiality Agreement shall remain in full force and effect in accordance with its terms.

(c) Without limiting the foregoing, each of Parent, Merger Sub and Merger Partnership shall comply with its obligations under all applicable data protection Laws relating to personally identifiable information provided to such parties by the Company or the Partnership in connection with the transactions contemplated by this Agreement (“PII”), shall hold all PII in confidence, and comply with the Company and the Partnership’s reasonable written instructions regarding the handling of PII consistent with applicable PURA provisions, ERCOT Protocols and practices and other applicable Law.

For the avoidance of doubt, this exclusive right of final approval shall not apply to joint pleadings filed in connection with the PUCT Filing.

(b) Subject to the terms and conditions set forth in this Agreement, the Company and the Partnership, on the one hand, and Parent, Merger Sub and Merger Partnership, on the other hand, shall cooperate with each other and use, and shall cause their respective Subsidiaries to use, their respective reasonable best efforts to take or cause to be taken all actions, and do or cause to be done, and assist and cooperate with the other parties to consummate and make effective the transactions contemplated by this Agreement, as promptly as reasonably practicable, including negotiating, preparing and filing as promptly as reasonably practicable all documentation to effect all necessary notices, reports and other filings and to obtain as promptly as reasonably practicable all consents, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any third party and/or any Governmental Entity in connection with the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated by this Agreement, including the following:

Each of the Company and Parent shall bear their own costs of complying with thisSection 5.7(b), and the Company and Parent shall each pay 50% of the applicable filing fee required under the HSR Act with respect to the transactions contemplated by this Agreement.

(ii) Parent, Merger Sub, Merger Partnership, the Company and the Partnership shall submit to the PUCT a single, integrated filing (jointly on behalf of the parties, including, to the extent applicable, the other parties to the transactions referred to below) that requests prior approval by the PUCT of the Mergers, the transactions contemplated by the Asset Exchange Agreement and the SU Investment (as defined in the Asset Exchange Agreement) (the “PUCT Filing”) as promptly as reasonably practicable

In particular, unless prohibited by Law or a Governmental Entity, no party shall make any filing, notification, submission of written materials or presentations to a Governmental Entity in connection with the Regulatory Approvals without first providing the other parties with a copy of such notification in draft form and giving such other parties a reasonable opportunity to comment on its content before it is filed with the relevant Governmental Entities, and such first party shall consider all reasonable comments timely made by the other parties in this respect. In exercising the foregoing rights and obligations, each of the Company, the Partnership, Parent, Merger Sub and Merger Partnership shall act reasonably and as promptly as reasonably practicable.

(vi) Parent, Merger Sub and Merger Partnership, on the one hand, and the Company and the Partnership, on the other hand, shall not schedule, participate in or initiate any meetings or communications with any Subject Governmental Entity in connection with the Regulatory Approvals without giving the other party or its Representatives a reasonable opportunity to participate in such meeting or communication unless prohibited by the applicable Subject Governmental Entity.

communications with Governmental Entities or Other Interested Parties in which they participate or of which they are aware regarding the transactions contemplated by this Agreement;provided,however, that nothing in thisSection 5.7 shall prevent, limit or restrict any party or its Affiliates from (A) interacting, communicating or making filings or applications with, or resolving any investigation or other inquiry of, any PUCT staff in connection with proceedings before the PUCT, other than proceedings with respect to the PUCT Filing and (B) responding to unsolicited inquiries related to the transactions contemplated by this Agreement from any Governmental Entity (provided,further, that in the case ofclause (B), such party will notify the other parties to this Agreement of any such unsolicited inquiries and such party’s response to the inquiries as promptly as reasonably practicable).

(vii) Parent, Merger Sub and Merger Partnership, on the one hand, or the Company and the Partnership, on the other hand shall be permitted to schedule, participate in or initiate any meetings or communications with any Other Interested Party without giving the other parties or their respective Representatives the opportunity to participate in any such meeting or communication (an “Interested Party Communication”);provided,however, that promptly following any Interested Party Communication, each party participating in such Interested Party Communication shall provide a reasonable summary of such communication to each party that did not participate therein.

(viii) Notwithstanding the foregoing, (A) commercially and/or competitively sensitive information and materials of a party will be provided to the other parties on an outside counsel-only basis while, to the extent feasible, making a version from which the commercial and/or competitively sensitive information has been redacted available to the other party and (B) no party will be required to provide the other party any personal identifying information that is submitted to CFIUS pursuant to the DPA.

(c) The Company and the Partnership, on the one hand, and Parent, Merger Sub and Merger Partnership, on the other hand, shall, upon request by the other, furnish the other with all information concerning itself, its Subsidiaries, Affiliates, directors, officers and equityholders and such other matters as may be reasonably necessary or advisable in connection with any statement, filing, notice or application made by or on behalf of Parent, Merger Sub, Merger Partnership, the Company, the Partnership or any of their respective Subsidiaries to or with any Governmental Entity in connection with the Regulatory Approvals.

(d) Subject to the terms and conditions set forth in this Agreement, without limiting the generality of the other undertakings pursuant to thisSection 5.7, each of the Company, the Partnership, Parent, Merger Sub and Merger Partnership shall use its reasonable best efforts to take, or cause to be taken, the following actions:

(i) the prompt provision to each and every federal, state, local or foreign court or Governmental Entity (including, for the avoidance of doubt, the FCC, the FERC and the PUCT) with jurisdiction over any Regulatory Approvals of information and documents reasonably requested by any such court or Governmental Entity or that are necessary, proper or advisable to permit consummation of the transactions contemplated by this Agreement;

(ii) obtaining the Regulatory Approvals as expeditiously as possible,provided that obtaining any such approval does not constitute a Burdensome Condition; and

(iii) the avoidance of the entry or enactment of any permanent, preliminary or temporary injunction or other order, decree, decision, determination, judgment or Law that, individually or in the aggregate, would reasonably be expected to prevent, enjoin or otherwise prohibit, or materially impair, restrain or restrict, the transactions contemplated by this Agreement,provided that such avoidance does not constitute a Burdensome Condition.

(e) Notwithstanding anything to the contrary in this Agreement, the “reasonable best efforts” standard set forth in thisSection 5.7 shall not in any event be construed to require Parent, Merger Sub, Merger Partnership or any of their respective Affiliates or direct or indirect equityholders, or permit or require (except as contemplated by this Agreement (excluding thisSection 5.7) or the Asset Exchange Agreement (excluding Section 5.05 thereof)) the Company, the Partnership or any of their respective Affiliates without the prior written consent of Parent to (i) sell or agree to sell, hold or agree to hold separate, or otherwise dispose or agree to dispose of any asset, (ii) conduct or agree to conduct its business in any particular manner (except as contemplated by this Agreement or the Asset Exchange Agreement), (iii) agree to any order, action or regulatory condition of any regulatory body, whether in an approval proceeding or another regulatory proceeding, that would constitute a Burdensome Condition or (iv) in connection with the CFIUS Approval, offer or agree to mitigation provisions that limit the right of any member of Parent to retain or exercise its governance rights, including any amendments, modifications, waivers or other changes to the governing agreements of Parent.

(f) Nothing in this Agreement shall require Parent, Merger Sub, Merger Partnership, the Company or the Partnership to make any filing in state or federal court to vacate, modify, reverse, remove, file exceptions to, file a motion for rehearing of, or appeal any permanent, preliminary or temporary injunction, decision, order, judgment, determination, decree or Law entered, issued or enacted by any Governmental Entity that would make consummation of the transactions contemplated by this Agreement unlawful, that would prevent, enjoin or otherwise prohibit, or in any manner impair, restrain or restrict, the transactions contemplated by this Agreement or that in any manner prohibits, modifies or alters this Agreement (or seeks to do the same), even if such decision order, judgment, determination, decree or Law imposes or seeks to impose obligations that do not constitute a Burdensome Condition; provided that no party shall be required to make any filing whatsoever to challenge any decision, order, judgment, determination or decree of the PUCT or the FERC;provided further, however, that if any of Parent, Merger Sub, Merger Partnership, the Company or the Partnership files exceptions to or a motion for rehearing or appeal of any permanent, preliminary or temporary injunction, decision, order, judgment, or determination, decree or Law entered, issued or enacted by any Governmental Entity, then no other Party shall oppose or contest such filing.

Section 5.8Takeover Laws. If any Takeover Law is or becomes applicable to Parent, Merger Sub, Merger Partnership, this Agreement, the Mergers or any of the other transactions contemplated hereby, the Company and the Company Board shall take all action necessary to ensure that the Mergers and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to eliminate or minimize the effect of such Takeover Law on this Agreement, the Mergers and the other transactions contemplated hereby.

Section 5.9Notification of Certain Matters.

(a) The Company and Parent shall promptly notify each other of (i) any notice or other communication received by such party from any Governmental Entity in connection with the Mergers or the other transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the Mergers or the other transactions contemplated hereby, (ii) any Action commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any Company Subsidiary which relate to the Mergers or the other transactions contemplated hereby (“Transaction Litigation”) or (iii) the discovery of any fact or circumstance that, or the occurrence ornon-occurrence of any event the occurrence ornon-occurrence of which would reasonably be expected to result in any of the conditions to the Mergers set forth inArticle VI not being satisfied or satisfaction of those conditions being materially delayed in violation of any provision of this Agreement;provided,however, that the delivery of any notice pursuant to thisSection 5.9(a) shall not (x) cure any breach of, ornon-compliance with, any other provision of this Agreement or (y) limit the remedies available to the party receiving such notice;providedfurther, that failure to give prompt notice pursuant toclause (iii) shall not constitute a failure of a condition to the Mergers set forth inArticle VI except to the extent that the underlying fact or circumstance not so notified would standing alone constitute such a failure.

(b) The Company and Parent shall keep the other parties reasonably informed with respect to the status of any Transaction Litigation if any such other party is not a party thereto. The Company shall reasonably consult with Parent and its Representatives with respect to the defense, negotiations or settlement of, any Transaction Litigation, and the Company shall consider in good faith Parent’s advice with respect to such Transaction Litigation. The Company shall not, and shall not permit any of its Subsidiaries nor any of its or their Representatives to, compromise, settle or come to a settlement arrangement regarding any Transaction Litigation or consent thereto unless Parent shall otherwise consent in writing (which consent shall not be unreasonably withheld, conditioned or delayed).

Section 5.10Indemnification, Exculpation and Insurance.

(a) From the Closing Date through the sixth anniversary of the Closing Date, Parent shall cause the Surviving Company to indemnify and hold harmless each present (as of the Company Merger Effective Time) and former officer or director, including but not limited to the members of the Conflicts Committee, of the Company and the Company Subsidiaries (the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any Action, whether civil, criminal, administrative or investigative, arising out of or pertaining to (i) the fact that the Indemnified Party is or was an officer, director, employee, fiduciary or agent of the Company or any of the Company Subsidiaries or (ii) acts or omissions taken by an Indemnified Party in their capacity as such or taken at the request of the Company or any of the Company Subsidiaries, whether asserted or claimed prior to, at or after the Company

Merger Effective Time, to the fullest extent the Company would have been permitted under applicable Law and the Company Charter and Company Bylaws as in effect at the date hereof. In the event of any such Action, (A) each Indemnified Party shall be entitled to advancement from the Surviving Company, within 10 Business Days of receipt by Parent or the Surviving Company from the Indemnified Party of a request therefor, of expenses incurred in the defense of any Action to the fullest extent permitted under applicable Law and the Company Charter and Company Bylaws as in effect at the date hereof;provided, that any Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification, (B) neither Parent nor the Surviving Company shall settle, compromise or consent to the entry of any judgment in any proceeding or threatened action, suit, proceeding, investigation or claim (and in which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, proceeding, investigation or claim or such Indemnified Party otherwise consents, and (C) the Surviving Company shall cooperate in the defense of any such matter.

(b) The certificate of formation and limited liability company agreement of the Surviving Company shall contain provisions no less favorable in the aggregate with respect to indemnification, advancement of expenses and exculpation of former or present directors and officers than are presently set forth in the Company Charter and Company Bylaws, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Company Merger Effective Time in any manner that would adversely affect in any material respect the rights thereunder of any such individuals.

(c) For a period of six years from the Closing Date, the Surviving Company shall either cause to be maintained in effect the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company and the Company Subsidiaries in effect on the date hereof (accurate and complete copies of which have been previously made available to Parent) with respect to matters arising on or before the Company Merger Effective Time or cause to be provided substitute policies or purchase, a “tail policy,” in either case of at least the same coverage and amounts containing terms and conditions that are not less advantageous in the aggregate than such policy with respect to matters arising on or before the Company Merger Effective Time;provided,however, that after the Company Merger Effective Time, the Surviving Company shall not be required to pay with respect to such insurance policies in respect of any one policy year annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverage required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount;providedfurther, that if the Surviving Company purchases a “tail policy” and the coverage thereunder costs more than 300% of such last annual premium, the Surviving Company shall purchase the maximum amount of coverage that can be obtained for 300% of such last annual premium. At the Company’s option, the Company may purchase, prior to the Company Merger Effective Time, asix-year prepaid “tail policy” on terms and conditions (in both amount and scope) providing substantially equivalent benefits as the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company and the Company Subsidiaries with respect to matters arising on or before the Company Merger Effective Time, covering without limitation the transactions contemplated hereby, subject to the limitations set forth in thisSection 5.10, and such “tail policy” shall satisfy the provisions of thisSection 5.10(c).

If such tail prepaid policy has been obtained by the Company prior to the Company Merger Effective Time, Parent shall cause such policy to be maintained in full force and effect, for a period of six years from the Closing Date, and cause all obligations thereunder to be honored by the Surviving Company.

(d) Notwithstanding anything herein to the contrary, if any Action (whether arising before, at or after the Company Merger Effective Time) is instituted against any Indemnified Party on or prior to the sixth anniversary of the Closing Date, the provisions of thisSection 5.10 shall continue in effect until the final disposition of such Action.

(e) The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to Law, Contract or otherwise. The provisions of thisSection 5.10 shall survive the consummation of the Mergers and, notwithstanding any other provision of this Agreement that may be to the contrary, expressly are intended to benefit, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal Representatives.

(f) In the event that the Surviving Company or any of its respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity of such consolidation or merger or (ii) transfers or conveys all or a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Company or Parent, as the case may be, shall succeed to the obligations set forth in thisSection 5.10.

Section 5.11Rule16b-3. Prior to the Company Merger Effective Time, the Company shall take such steps as may be reasonably necessary or advisable hereto to cause dispositions of Company equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of the Company to be exempt underRule 16b-3 promulgated under the Exchange Act.

Section 5.12Dividends. From and after the date hereof and prior to the Partnership Merger Effective Time, (a) the Company may make distributions to its stockholders, the Partnership may make distributions to the Company, and any direct or indirect Company Subsidiary may make distributions to the Partnership, to allow for regular quarterly cash dividends of $0.25 per share to be paid on the Company Shares and Partnership Units (including, in the event the Closing does not coincide with the end of a quarter, a prorated portion of the $0.25 per share quarterly cash dividend on the Company Shares and Partnership Units for the quarter in which the Closing occurs) and (b) upon consultation with Parent, the Company shall make distributions to its stockholders (and as necessary the Partnership shall make distributions to the Company, and any direct or indirect Subsidiary of the Partnership may make distributions to the Partnership, as needed in order to facilitate such distributions by the Company) so as to (i) maintain the Company’s qualification for taxation as a REIT under the Code and (ii) avoid the payment of income or excise tax under Sections 857 or 4981 of the Code (or any other entity-level Tax), in each case taking into account the taxable gain recognized in the deemed sale and subsequent deemed liquidating distribution occurring at the Company Merger Effective Time (as described inSection 1.9). If the Company is required to pay a distribution described inclause (b) of the first sentence of thisSection 5.12, or if the Company declares any other distribution on the Company

Shares on or prior to the Company Merger Effective Time (other than as described inclause (a) of the first sentence of thisSection 5.12), the Per Share Merger Consideration shall be decreased by the amount of the per Company Share amount of any such distribution(s). For the avoidance of doubt and consistent withSection 2.1(b)(i), any reduction in the Per Share Merger Consideration pursuant to the provisions of thisSection 5.12 will give rise to an identical reduction in the Per Partnership Unit Merger Consideration.

Section 5.13Public Announcements. Except with respect to (a) an Adverse Recommendation Change, (b) a press release or other public statement that is consistent in all material respects with previous press releases, public disclosures or public statements made by a party hereto in accordance with this Agreement, including in investor conference calls, SEC filings, Q&As or other publicly disclosed documents, in each case under thisclause (b), to the extent such disclosure is still accurate in all material respects (and not misleading), (c) as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system or (d) in connection with a dispute between the parties hereto regarding the transactions contemplated hereby, each of Parent, Merger Sub and Merger Partnership, on the one hand, and the Company and the Partnership, on the other hand, shall, to the extent reasonably practicable, consult with each other before issuing, and give each other a reasonable opportunity to review and comment upon, any press release or other public statements with respect to this Agreement, the Mergers and the other transactions contemplated hereby and shall not issue any such press release or make any public announcement without the prior written consent of the other party, which consent shall not be unreasonably withheld or delayed.

Section 5.14Obligations ofParent and theCompany. Whenever this Agreement requires a Subsidiary of Parent (including, for the avoidance of doubt, the Surviving Company or the Surviving Partnership) to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action. Whenever this Agreement requires a Company Subsidiary to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Company Subsidiary to take such action and, after the Company Merger Effective Time, on the part of the Surviving Company to cause such Company Subsidiary to take such action.

Section 5.15Tax Matters.

(a) Notwithstanding anything to the contrary set forth in this Agreement, but subject toSections 5.1(b)(iv), 5.1(b)(v),5.1(b)(xiii),5.1(b)(xiv) and5.12, the Company shall take all actions, and refrain from taking all actions, that in the reasonable judgment of the Company Board, upon advice of counsel to the Company, and upon consultation with Parent, as necessary to ensure that the Company (i) will qualify for taxation as a REIT for U.S. federal income tax purposes for its current taxable year and any other taxable year that includes the Closing Date, (ii) will not become liable for U.S. federal income Tax under Sections 856(g)(5)(C), 857(b)(1), 857(b)(4), 857(b)(5), 857(b)(6)(A), 857(b)(7), 857(f), 860(c) or 4981 of the Code or Section 337(d) (and/or Section 1374) of the Code (and the applicable Treasury Regulations thereunder) and similar provisions of state or local Tax law and (iii) preserves the U.S. federal income Tax status of any Company Subsidiary as a disregarded entity, partnership, Qualified REIT Subsidiary or Taxable REIT Subsidiary, as the case may be. After the date of this Agreement and

prior to the Company Merger Effective Time, the Company shall cooperate in good faith to address all reasonable requests of Parent with respect to maintenance of the Company’s qualification for taxation as a REIT for the Company’s 2015 through 2017 taxable years (including with respect to the filing of the 2017 IRS Form 1120-REIT) and the continuation of such qualification for taxation as a REIT for the taxable year ending with the Company Merger Effective Time.

(b) Parent and the Company shall, upon written request, use their commercially reasonable efforts to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated in this Agreement).

(c) On and after the Company Merger Effective Time, Parent and the Surviving Company shall take all commercially reasonable actions, and refrain from taking all actions, as customary to enable the Company to qualify for taxation as a REIT for U.S. federal income tax purposes for its current taxable year and any other taxable year that includes the Closing Date;provided,however, that nothing in thisSection 5.15(c) shall obligate Parent or the Surviving Company to take or pursue any Action in a court.

(d) The Company shall prepare or cause to be prepared and timely file or cause to be timely filed (taking into account any applicable extensions of time) all Tax Returns for the Company and each Company Subsidiary required to be filed (taking into account any applicable extensions of time) prior to the Closing Date for all taxable periods ending prior to the Closing Date, including timely filing of Tax Returns for the fiscal year ended December 31, 2017 (taking into account any applicable extensions of time) to the extent such Tax Returns are required to be filed prior to the Closing Date. Any such Tax Returns prepared by the Company shall be prepared in a manner consistent with the historic Tax accounting practices of the Company (except as may be required under applicable Tax Law, this Agreement or with the prior written consent of Parent, such consent not to be unreasonably withheld, conditioned or delayed). The Company shall pay all Taxes shown as due on such Tax Returns. In the case of Tax Returns that both relate to income Taxes or the Texas franchise Tax for taxable periods ending prior to the Closing Date and are to be filed by the Company after the date of this Agreement and on or prior to the Closing Date, the Company shall provide to Parent copies of such Tax Returns at least thirty (30) calendar days prior to the due date of such Tax Returns (including applicable extensions). Parent shall cause to be timely filed all Tax Returns for the Company and each Company Subsidiary that are required to be filed on or after the Closing Date.

(e) On the Closing Date, prior to the Company Merger, the Company shall deliver to Parent a duly executed certificate ofnon-foreign status, dated as of the Closing Date, substantially in the form of the sample certification set forth in Treasury RegulationsSection 1.1445-2(b)(2)(iv)(B) and including any additional information as may be required by Treasury Regulations promulgated under Section 1446(f)(2). On the Closing Date, prior to the Partnership Merger, the Partnership shall deliver to Parent a duly executed certificate ofnon-foreign status from each Person that constitutes and is treated as a partner for U.S. federal income tax purposes (or, in the case of any such Person that is a disregarded entity, such Person’s sole owner for U.S. federal income tax purposes) and that has provided such a certificate to the Partnership. The receipt of such certificates by Parent shall not be a condition to the Partnership Merger or the other transactions contemplated hereby, but if Parent has not received such

certificate from or with respect to a partner (or such partner’s sole owner, as applicable), Parent shall be entitled to withhold any applicable U.S. tax on cash distributed to or on behalf of such Person (as determined by Parent in its sole discretion), in accordance with Sections 1445 and 1446(f) of the Code.

Section 5.16Stock Exchange Delisting. The Company shall cooperate with Parent and take, or cause to be taken, all actions, and do, or cause to be done, all things reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of the NYSE to enable the delisting by the Surviving Company of the Company Shares from the NYSE and the deregistration of the Company Shares under the Exchange Act as promptly as practicable after the Company Merger Effective Time, and, in any event, no more than 10 days after the Closing Date.

Section 5.17Financing.

(a) From the date of this Agreement until the earlier of the Closing Date and the Termination Date, each of the Company and the Partnership agrees to use reasonable best efforts to provide, and to use reasonable best efforts to cause the Company Subsidiaries (other than the Partnership) and each of their respective Representatives to provide, such cooperation as may be reasonably requested by Parent in connection with the arrangement of the receipt of proceeds (x) from an issuance of equity by Parent or any of its direct or indirect equityholders (the “Equity Financing”) or (y) from an issuance of debt by Parent or any of its direct or indirect equityholders (the “Debt Financing,” with the Equity Financing and Debt Financing each referred to hereafter as a “Financing”), including reasonable best efforts to (i) provide assistance with any discussions of and/or furnish, as applicable, such business, financial statements, pro forma financials, projections, management discussion and analysis and other customary financial data and information reasonably required in connection with any Financing, all for use in connection therewith, (ii) direct their respective independent accountants to provide customary and reasonable assistance in connection with any Financing, including in connection with providing customary comfort letters and consents, (iii) obtain customary payoff letters, releases of liens and other instruments of termination or discharge reasonably requested by Parent or any of its direct or indirect equityholders in connection with the repayment of indebtedness of the Company, the Partnership and their respective Subsidiaries as necessary to consummate the transactions contemplated by this Agreement and (iv) subject toSection 5.19(a), authorize and facilitate discussions, meetings and other engagement by Parent, its Subsidiaries or Affiliates, Hunt Manager, its Subsidiaries or Affiliates, or SU, its Subsidiaries or Affiliates, with the current lenders, noteholders or other providers of Existing Indebtedness to the Company or the Company Subsidiaries for the purpose of obtaining Debt Financing, including by necessary or appropriate waivers of the Confidentiality Agreement to permit such activities. Parent shall reimburse the Company for all reasonableout-of-pocket costs or expenses incurred by the Company and the Company Subsidiaries in connection with cooperation provided for in thisSection 5.17(a) to the extent the information requested was not otherwise prepared or available in the ordinary course of business. Any lender, underwriter, arranger, manager, placement agent or similar entity in connection with any Financing by Sempra or its Affiliates shall be deemed to be a “Representative” of Sempra for the purposes of the Amended and Restated Confidentiality Agreement, dated June 18, 2018, by and between Sempra Energy and the Company. Any lender, underwriter, arranger, manager, placement agent or similar entity in connection with any Financing by Parent or its Affiliates shall be deemed to be a “Representative” of Parent for purposes of the Confidentiality Agreement.

(b) From and after the date hereof until the earlier of the Termination Date and the Closing Date, it is understood that Parent or any of its direct or indirect equityholders may seek to market and consummate all or a portion of any Financing. In this regard, and for the avoidance of doubt, each of the Company and the Partnership acknowledges that its cooperation obligations set forth inSection 5.17(a) include the obligation upon the reasonable request of Parent to use its reasonable best efforts to cooperate with any such efforts;provided, that such cooperation obligations are limited to those set forth inSection 5.17(a).

(c) Prior to the Closing Date, none of the Company, the Company Subsidiaries and their respective Representatives shall be required to take any action that would subject such Person to actual or potential liability, to bear any cost or expense or to pay any commitment or other similar fee or make any other payment or incur any other liability or provide or agree to provide any indemnity in connection with any Financing or their performance of their respective obligations under thisSection 5.17 or any information utilized in connection therewith. Parent shall indemnify and hold harmless the Company and the Company Subsidiaries and their respective Representatives from and against any and all costs suffered or incurred by them in connection with the arrangement of any Financing and the performance of their respective obligations under thisSection 5.17 and any information utilized in connection therewith (other than arising from information provided by the Company or the Company Subsidiaries specifically for use in the Financing pursuant toSection 5.17(a)). Each of the Company and the Partnership hereby consents to the use of the logos of the Company, the Partnership and their respective Subsidiaries in connection with any Financing;provided, that such logos are used solely in a manner that is not intended to or reasonably likely to harm or disparage the Company, the Partnership or any of their respective Subsidiaries or the reputation or goodwill of the Company, the Partnership or any of their respective Subsidiaries.

(d) Parent, Merger Sub and Merger Partnership acknowledge and agree that the consummation of the transactions contemplated by this Agreement is not conditioned upon the consummation of, or the receipt by Parent or any of its direct or indirect equityholders or any of their Affiliates of the proceeds of, the Financing.

(e) Parent shall not, without the prior written consent of the Company, permit any amendment or modification to, or any waiver of any provision (including any remedy) under, or voluntarily replace the Equity Commitment Letters if such amendment, modification, waiver or voluntary replacement (i) adds new (or adversely modifies any existing) conditions to the consummation of the equity financing as compared to those in the Equity Commitment Letters, each as in effect on the date of this Agreement, in a manner that would make any portion of the equity financing less likely to be timely obtained, (ii) adversely affects the ability of Parent to enforce its rights against other parties to the Equity Commitment Letters or any definitive agreements relating to the equity financing as so amended, replaced, supplemented or otherwise modified, in any material respect, relative to the ability of Parent to enforce its rights against such other parties to the Equity Commitment Letters, each as in effect on the date hereof or in the applicable definitive agreements relating to the equity financing, (iii) reduces the aggregate amount of the equity financing (other than reductions of any amounts thereof constituting increases thereto after the date hereof), or (iv) would otherwise prevent, impede or delay the consummation of any of the transactions contemplated hereby;provided, that for the avoidance of doubt no consent from the Company shall be required for any amendment, replacement, supplement or modification of the Equity Commitment Letters that is limited to adding any direct or indirect equityholders of Parent that have not executed the Equity Commitment Letters as of the date of this Agreement.

Section 5.18APM Private Letter Ruling.

(a) Parent and the Partnership shall use commercially reasonable efforts to, as promptly as reasonably practicable after the date of this Agreement, jointly prepare and file with the IRS written requests (collectively, the “Ruling Request,” and together with all related materials and supplements thereto filed or to be filed with the IRS, the “IRS Submissions”) that the IRS issue a private letter ruling or rulings (the “APM Private Letter Ruling”) to the effect that a normalization violation will not occur if the Partnership does not adjust existing accumulated deferred federal income tax balances to account for the consequences of the basis adjustment under Section 743(b) of the Code resulting from the Mergers.

(b) Each party shall provide the other party and its tax counsel with copies of, and a reasonable opportunity to review and comment on, drafts of all proposed IRS Submissions prepared by the first party and will incorporate any comments or suggested revisions as are reasonably requested by the other party or its tax counsel with respect thereto;provided,however, that the rights to review and comment granted hereunder shall not result in unreasonable delays in submitting the IRS Submissions to the IRS. To the extent that a party, in its good faith judgment, considers any information included in such IRS Submissions (or drafts thereof) to be confidential, such party may require that any such documents provided to the other party be redacted to exclude such information. Subject to the foregoing, a party filing an IRS Submission shall provide the other party with copies of such IRS Submission promptly following the filing thereof.

(c) A Representative of each of Parent and the Partnership shall be given the opportunity to participate in all substantive scheduled communications with the IRS concerning the IRS Submissions, including all substantive scheduled conference calls andin-person meetings. In addition, each party (i) shall keep the other party reasonably informed and shall consult in good faith with the other party and its tax counsel with respect to any issue relating to the IRS Submissions and (ii) shall provide the other party with copies of all correspondence, notices, and other written materials received from the IRS and shall otherwise keep the other party and its tax counsel advised of significant developments, and of any substantive communications, in each case, regarding the IRS Submissions and the Mergers. Each party agrees to cooperate and use its commercially reasonable efforts to assist in obtaining the APM Private Letter Ruling requested in the Ruling Request. Each party agrees to use commercially reasonable efforts to provide any appropriate information and additional representations as requested by the IRS in order to issue the APM Private Letter Ruling. No additional rulings will be requested unless mutually agreed by the parties.

(d) To the extent that the procedures described inSection 5.18(b) andSection 5.18(c) differ from the procedures applicable to any other regulatory filings described in this Agreement, the procedures described inSection 5.18(b) andSection 5.18(c) shall govern.

(e) Each of the parties hereby expressly acknowledges and agrees that the obligations of the parties to consummate the Mergers are not conditioned in any way on the issuance or receipt of the APM Private Letter Ruling or on obtaining any specific ruling from the IRS requested in the IRS Submission.

(f) Parent shall bear, and reimburse the Partnership for, allout-of-pocket costs incurred by the Partnership in connection with the Ruling Request, the IRS Submissions and the APM Private Letter Ruling.

During the Consent Period, except upon the prior written request of the Company, Parent shall not, and shall cause its Representatives and Affiliates not to, schedule, participate in or initiate any meetings or communications with any of the Noteholders or, subject toSection 5.14, make any public statements with respect to the subject matter of thisSection 5.19. Prior to commencing the solicitation of the Noteholder Consents pursuant to thisSection 5.19(a), the Company shall provide Parent a reasonable opportunity to review and comment on the material documents by which the Noteholder Consents will be solicited or effected and will consider comments from Parent in good faith. As reasonably requested by Parent, the Company shall provide information regarding the status of the Noteholder Consent process.

(b) In the event that:

(i) this Agreement is terminated by either Parent or the Company pursuant toSection 7.1(b)(i) orSection 7.1(b)(iv) or by Parent pursuant toSection 7.1(d)(i) and (A) (1) prior to the Termination Date in the event of a termination pursuant toSection 7.1(b)(i) orSection 7.1(d)(i) or (2) prior to the Company Stockholders Meeting in the event of a termination pursuant toSection 7.1(b)(iv), (x) a bona fide Acquisition Proposal shall have been received by the Company, the Company Board or any Representative of the Company or (y) any Person shall have publicly proposed or publicly announced an intention (whether or not conditional) to make an Acquisition Proposal and, with respect toclauses (x) and(y), in the case of a termination pursuant toSection 7.1(b)(i) orSection 7.1(d)(i), not withdrawn prior to such termination, and in the case of a termination pursuant toSection 7.1(b)(iv) not publicly withdrawn at least two Business Days prior to the Company Stockholders Meeting and (B) within 12 months after such termination, the Company or any Company Subsidiary enters into a definitive agreement with respect to an Acquisition Proposal (provided, that for purposes thisSection 7.3(b)(ii), the references to “20% or more” in the definition of Acquisition Proposal shall be deemed to be references to “more than 50%”) that is later consummated, then promptly (but in no event later than three Business Days) after the consummation of such Acquisition Proposal, the Company shall pay to Parent the Termination Fee;

(ii) this Agreement is terminated by the Company pursuant toSection 7.1(c)(ii), then prior to or concurrently with (and as a condition to) such termination, the Company shall pay to Parent the Termination Fee; or

(c) Payment of the Termination Fee, if applicable, shall be made by wire transfer ofsame-day funds to the account or accounts designated by Parent.

(d) The Company acknowledges that the agreements contained in thisSection 7.3 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent, Merger Sub and Merger Partnership would not enter into this Agreement. The Company acknowledges that the Termination Fee is not a penalty, but is liquidated damages, in reasonable amounts that will compensate Parent in the circumstances in which such fee is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. Accordingly, if the Company fails promptly to pay any amounts due pursuant to thisSection 7.3, and, in order to obtain such payment, Parent, Merger Sub or Merger Partnership commences a suit that results in a judgment against the Company for the amounts set forth in thisSection 7.3, the Company shall pay to Parent, Merger Sub or Merger Partnership its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts due pursuant to thisSection 7.3 from the date such payment was required to be made until the date of payment at the prime lending rate as published inThe Wall Street Journal in effect on the date such payment was required to be made plus two percent per annum.

(e) Notwithstanding anything to the contrary in this Agreement, except in the case of actual and intentional fraud or a Willful and Material Breach of this Agreement by the Company, if this Agreement is terminated under circumstances in which the Company is required to pay the Termination Fee and the Termination Fee is actually paid to Parent in accordance with thisSection 7.3, the payment of the Termination Fee (and any amounts payable pursuant toSection 7.3(d)) shall be Parent’s, Merger Sub’s and Merger Partnership’s sole and exclusive remedy against the Company and its Affiliates, and their respective shareholders and Representatives, relating to or arising out of this Agreement, any agreement entered into in connection herewith or the transactions contemplated by this Agreement or thereby

Section 7.4Amendment or Supplement. This Agreement may be amended, modified or supplemented by the parties by action taken or authorized by their respective Boards of Directors (or equivalent governing body) at any time prior to the Company Merger Effective Time, whether before or after the Company Stockholder Approval has been obtained;provided,however, that after the Company Stockholder Approval has been obtained, no amendment may be made that pursuant to applicable Law requires further approval or adoption by the stockholders of the Company without such further approval or adoption. This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each of the parties in interest at the time of the amendment.

Section 7.5Extension of Time; Waiver; Any Determinations, Decisions, Etc. At any time prior to the Company Merger Effective Time, the parties may, by action taken or authorized by their respective Boards of Directors, to the extent permitted by applicable Law, (a) extend the time for the performance of any of the obligations or acts of the other party, (b) waive any inaccuracies in the representations and warranties of the other parties set forth in this Agreement or any document delivered pursuant hereto or (c) subject to applicable Law, waive compliance with any of the agreements or conditions of the other parties contained herein; provided, however, that after the Company Stockholder Approval has been obtained, no waiver may be made that pursuant to applicable Law requires further approval or adoption by the stockholders of the Company without such further approval or adoption. Any agreement on the part of a party to any such waiver shall be valid only if set forth in a written instrument executed and delivered by a duly authorized officer on behalf of such party. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. Whenever a determination, decision, approval, notice or consent of the Company is permitted or required pursuant to or otherwise in connection with this Agreement, including, without limitationSection 5.4,Section 7.4 andSection 7.5, such determination, decision, approval, notice or consent must be authorized or made by the Conflicts Committee.
