In connection with the GP Merger, at the Effective Time:

Treatment of Partnership Equity Awards

Each award of phantom units that corresponds to Partnership Common Units and vests solely based on the passage of time, whether vested or unvested, that is outstanding immediately prior to the Effective Time, will be assumed by Energy Transfer as of the Effective Time and converted into a restricted unit award (or, upon the election of seconded employees, the right to receive the cash equivalent thereof) on the same terms and conditions with respect to a number of common units representing limited partner interests in Energy Transfer (the “Energy Transfer Common Units”) equal to the product obtained by multiplying (x) the number of Partnership Common Units subject to such Partnership phantom unit award immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up or down to the nearest whole Energy Transfer Common Unit. Each converted restricted unit award will otherwise be subject to the same terms and conditions (including as to vesting, distribution equivalent rights and issuance) as were applicable to the Partnership phantom unit award immediately prior to the Effective Time.

Each award of performance units that corresponds to Partnership Common Units that is outstanding and unvested as of the Effective Time, will, as of the Effective Time, be measured as to performance as of the Effective Time (or a date reasonably proximate thereto) as determined in good faith by the Compensation Committee of the board of directors of the General Partner and will be assumed by Energy Transfer and converted into restricted unit awards based on the higher of actual performance or target (“Earned Performance Unit”) (except with respect to awards of performance units granted in 2021 the number of Earned Performance Units shall be equal to the target number of units granted, regardless of performance), which shall have distribution equivalent rights and be eligible to vest solely based on continued service at the end of the performance period that was originally applicable thereto; provided, however, that the Earned Performance Units will vest upon a “qualifying termination” and, to the extent applicable, will incorporate the provisions related to termination due to “retirement,” as provided in the Partnership phantom unit awards. The number of Parent Common Units that are subject to such converted restricted unit awards will be equal to the number of Earned Performance Units with respect to the corresponding award of performance units, multiplied by the Exchange Ratio, rounded up or down to the nearest whole Energy Transfer Common Unit. Any performance units that correspond to Partnership Common Units that are not Earned Performance Units shall, upon the Effective Time, automatically be cancelled for no consideration.

Conditions to the Mergers

The completion of the Mergers is subject to various customary closing conditions, including, among other things, (i) the adoption of the Merger Agreement by holders of a majority of the outstanding Partnership Common Units, voting as a single class, entitled to vote thereon, (ii) absence of any court order or regulatory injunction prohibiting completion of the Mergers or the other transactions contemplated by the Merger Agreement, (iii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (iv) the effectiveness of the registration statement on Form S-4 (the “Form S-4”) that Energy Transfer is obligated to file with the Securities and Exchange Commission (“SEC”) in connection with the issuance of Energy Transfer Common Units in the LP Merger, (v) the authorization for listing of Energy Transfer Common Units to be issued in the LP Merger on the New York Stock Exchange, (vi) receipt of applicable tax opinions from each of Energy Transfer’s and the Partnership’s tax counsel, and (vii) the accuracy of each party’s representations and warranties (subject to certain materiality qualifiers) and compliance by each party with its covenants under the Merger Agreement in all material respects.

Termination Rights

The Merger Agreement contains certain termination rights for both the Partnership and Energy Transfer, including, among other things: (i) by mutual written consent of the Partnership and Energy Transfer; (ii) by the Partnership or Energy Transfer, if the LP Merger is not consummated on or prior to November 30, 2021, provided, however, that if all closing conditions (other than the conditions pertaining to the absence of court orders and regulatory injunctions and termination of regulatory waiting periods) are satisfied or are capable of being satisfied at such time, such date will automatically be extended to February 28, 2022; (iii) by the Partnership or Energy Transfer, if an injunction or other law is entered, enacted or becomes effective permanently restraining, enjoining or otherwise prohibiting the consummation of the Mergers; (iv) by the Partnership, if Energy Transfer, Merger Sub or GP Merger Sub breaches or fails to perform any of their representations, warranties, covenants or other agreements under the Merger Agreement, (v) by Energy Transfer, if the Partnership or the General Partner breaches or fails to

3

perform any of its representations, warranties, covenants or other agreements under the Merger Agreement, and (vi) by Energy Transfer upon any willful breach by the Partnership or the General Partner of the non-solicitation covenant, which materially impedes, interferes with or hinders the consummation of the Mergers by the End Date (as defined in the Merger Agreement). If the Merger Agreement is terminated by Energy Transfer pursuant to clause (vi), then the Partnership will be required to pay Energy Transfer a termination fee of $97.5 million (the “Breakup Fee”). The Partnership will also be required to pay the Breakup Fee to Energy Transfer if Energy Transfer terminates the Merger Agreement pursuant to clause (iv) above, and (a) prior to such termination a third party has made an acquisition proposal, which shall have been publicly announced or disclosed to the General Partner or its affiliates and not have been withdrawn prior to such termination and (b) within 12 months after the date of such termination, the Partnership enters into a definitive agreement with respect to, or consummates, an acquisition proposal.

Other Terms of the Merger Agreement

The Merger Agreement contains customary representations, warranties and covenants for a transaction of this nature, including covenants and agreements relating to (i) the obligation of the Partnership and Energy Transfer to conduct their respective businesses in the ordinary course and to refrain from taking certain specified actions without the consent of the other party, (ii) obligation of the Partnership and the General Partner, their Subsidiaries and respective representatives (A) to cease and terminate any discussions relating to any acquisition proposal and (B) not to, among other things, to directly or indirectly solicit, initiate, knowingly encourage or knowingly facilitate any inquiries or the making of any proposal or offer that constitutes, or would reasonably be expected to lead to, an acquisition proposa, or and (ii) the efforts of the parties to cause the Mergers to be completed, including actions which may be necessary to cause the expiration or termination of the waiting period under the HSR Act, if applicable. Pursuant to the terms of the Merger Agreement, the Partnership and Energy Transfer have agreed to (including to cause their respective subsidiaries to) take all necessary action to resolve any objections that a governmental authority may assert under antitrust laws with respect to the Mergers, and to avoid or eliminate each and every impediment under any antitrust law that may be asserted by any governmental authority with respect to the Mergers, in each case, so as to enable the closing of the Mergers to occur as promptly as practicable and in any event no later than on February 28, 2022, including negotiating, committing to and effecting by consent decree, hold separate orders, or otherwise, the sale, divestiture or disposition of such of Energy Transfer’s and its Subsidiaries’ assets, properties or businesses or of the Partnership’s properties or businesses, excluding any action which would require such party to offer, negotiate, commit to, effect, enter into or take any action, agreement, condition, commitment or remedy of any kind, including but not limited to any sale, divestiture or disposition of any assets, properties or businesses of Energy Transfer, the Partnership or their respective subsidiaries or affiliates that would require such party to sell, divest, lease, license, transfer, dispose of, or otherwise encumber, impair, limit or restrict Energy Transfer’s or its subsidiaries’ ownership, control, management or operation of assets or businesses (including for the avoidance of doubt, any equity or other interests) of Energy Transfer, the Partnership or any of their respective subsidiaries or affiliates (other than CNP and OGE Energy Corp., an Oklahoma corporation (“OGE”) and their respective affiliates (other than the Partnership and its subsidiaries)) meeting or exceeding the Remedy Threshold (as such term is defined in the Merger Agreement).

Pursuant to the Support Agreements, neither of the Sponsors nor any of their representatives are permitted to solicit, initiate, knowingly encourage or knowingly facilitate any acquisition proposals or inquiries regarding the submission of an acquisition proposal or any inquiries regarding any transfer of limited liability company interests in the General Partner or engage or participate in any discussions or negotiations regarding, or furnish any confidential information regarding or in connection with an acquisition proposal or any transfer of limited liability company interests in the General Partner or enter into any agreement with respect to an acquisition proposal or transfer of limited liability company interests in the General Partner or resolve to approve an acquisition proposal or transfer of limited liability company interests in the General Partner.

Forward-Looking Statements and Cautionary Statements

The foregoing contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical fact, included in this communication that address activities, events or developments that the Partnership or Energy Transfer expects, believes or anticipates will or may occur in the future are forward-looking statements. Words such as “may,” “assume,” “forecast,” “position,” “predict,” “strategy,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” “budget,” “potential,” or “continue,” and similar expressions are used to identify forward-looking statements. They can be affected by assumptions used or by known or unknown risks or uncertainties. Consequently, no forward-looking statements can be guaranteed. However, the absence of these words does not mean that the statements are not forward-looking. These forward-looking statements include, but are not limited to, statements regarding the Mergers, pro forma descriptions of the company and its operations following the Mergers, integration and transition plans, anticipated cost savings, tax benefits and synergies, opportunities and anticipated future performance. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this communication. These include the expected timing and likelihood of completion of the Mergers, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the Mergers that could reduce anticipated benefits or cause the parties to

6

abandon the Mergers, the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, the possibility that unitholders of the Partnership may not approve the Mergers, the risk that the parties may not be able to satisfy the conditions to the Mergers in a timely manner or at all, risks related to disruption of management time from ongoing business operations due to the Mergers, the risk that any announcements relating to the Mergers could have adverse effects on the market price of Energy Transfer’s or the Partnership’s common units, the risk that the Mergers and its announcement could have an adverse effect on the ability of the Partnership and Energy Transfer to retain and hire key personnel, on the ability of the Partnership to attract third-party customers and maintain its relationships with joint venture counterparties and on the Partnership’s operating results and businesses generally, including the ongoing COVID-19 pandemic, the risk the pending Mergers could distract management of both entities and they will incur substantial costs, the risk that problems may arise in successfully integrating the companies, which may result in the companies not operating as effectively and efficiently as expected following the Mergers, the risk that the parties may be unable to achieve the anticipated benefits or any other synergies from the Mergers or that it may take longer than expected to achieve those benefits and synergies and other important factors that could cause actual results to differ materially from those projected. All such factors are difficult to predict and are beyond the Partnership’s or Energy Transfer’s control, including those detailed in the Partnership’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on its website at http:// http://www.enablemidstream.com and on the SEC’s website at http://www.sec.gov, and those detailed in Energy Transfer’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on Energy Transfer’s website at http://www.energytransfer.com and on the SEC’s website at http://www.sec.gov. All forward-looking statements are based on assumptions that the Partnership or Energy Transfer believe to be reasonable but that may not prove to be accurate. Any forward-looking statement speaks only as of the date on which such statement is made, and the Partnership and Energy Transfer undertake no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof.

(a) For purposes of furthering the transactions contemplated hereby, each of the Partnership and Parent shall afford the other party and (i) the officers and employees and (ii) the accountants, consultants, legal counsel, financial advisors, financing sources and agents and other representatives (such persons described in this clause (ii), collectively, “Representatives”) of such other party reasonable access during normal business hours, throughout the period prior to the earlier of the Effective Time and the Termination Date, to its and its Subsidiaries’ key employees and properties, contracts, commitments, books and records and any report, schedule or other document filed or received by it pursuant to the requirements of applicable Laws and with such additional accounting, financing, operating, environmental and other data and information regarding the Partnership and its Subsidiaries, as Parent may reasonably request, and Parent and its Subsidiaries, as the Partnership may reasonably request, as the case may be (including information necessary to prepare the Combined Consent Statement/Prospectus). Notwithstanding the foregoing, neither the Partnership nor Parent shall be required to afford such access to the extent it would unreasonably disrupt the operations of such party or any of its Subsidiaries, would cause a violation of any agreement to which such party or any of its Subsidiaries is a party, would cause a risk of a loss of privilege to such party or any of its Subsidiaries, would constitute a violation of any applicable Law or would interfere with the ability of such party or any of its Subsidiaries’ ability to comply with any COVID-19 Measures. Neither the Partnership nor Parent, nor any of their respective officers, employees or Representatives, shall be permitted to perform any onsite procedures (including an onsite study or any Phase II environmental site assessment or other invasive or subsurface testing, sampling, monitoring or analysis) with respect to any property of the other party or any of the other party’s Subsidiaries without the other party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

- 56 -

Nothing in this Section 5.4 shall prohibit the Partnership, or the GP Board, directly or indirectly through any officer, employee or Representative, from informing any person that the Partnership is party to this Agreement and informing such person of the restrictions that are set forth in this Section 5.4.

(b) Following the execution of this Agreement, each of the Partnership and the General Partner shall, and each of them shall cause their respective Subsidiaries, and the respective directors, officers, employees of the Partnership, the General Partner and such Subsidiaries to, and shall use its reasonable best efforts to cause the Representatives of the Partnership, the General Partner and such Subsidiaries to, immediately cease and terminate any discussions existing as of the date of this Agreement between the Partnership or any of its Subsidiaries or any of their respective officers, directors, employees or Representatives and any person (other than Parent, Merger Sub, GP Merger Sub or any of their respective officers, directors, employees or Representatives) that relate to any Acquisition Proposal.

(c) As used in this Agreement:

(i) “Acquisition Proposal” means any bona fide offer or proposal, whether or not in writing, received from or made public by a third party (other than an offer, proposal by Parent, Merger Sub, GP Merger Sub or their respective affiliates) relating to any Acquisition Transaction; and

- 57 -

(ii) “Acquisition Transaction” means any transaction or series of related transactions (other than the transactions contemplated by this Agreement) pursuant to which any person, other than Parent, Merger Sub or their respective affiliates, (A) directly or indirectly acquires (whether in a single transaction or a series of related transactions, and whether through merger, tender offer, exchange offer, business combination, consolidation or otherwise) assets of the Partnership and its Subsidiaries equal to 25% or more of the Partnership’s consolidated assets (based on their fair market value thereof) or to which 25% or more of the Partnership’s revenues or earnings on a consolidated basis are attributable, or (B) directly or indirectly acquires (whether in a single transaction or a series of related transactions, and whether through merger, tender offer, exchange offer, business combination, consolidation or otherwise) beneficial ownership (within the meaning of Section 13 under the Exchange Act) 25% or more of any class of equity securities of the Partnership entitled to vote with respect to the approval of this Agreement.

Section 5.5 Filings; Other Actions.

(a) As promptly as reasonably practicable following the date of this Agreement, Parent and the Partnership shall prepare and file with the SEC the Form S-4, which will include the Combined Consent Statement/Prospectus. Each of Parent and the Partnership shall use reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective as long as necessary to consummate the LP Merger and the other transactions contemplated hereby. Parent shall also take any action required to be taken under any applicable state or provincial securities laws in connection with the issuance and reservation of Parent Common Units in the LP Merger, and the Partnership shall furnish all information concerning the Partnership and the holders of Partnership Common Units, or holders of a beneficial interest therein, as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Combined Consent Statement/Prospectus will be made by Parent or the Partnership, as applicable, without the other’s prior consent (which shall not be unreasonably withheld, conditioned or delayed) and without providing the other party a reasonable opportunity to review and comment thereon. Parent or the Partnership, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the Parent Common Units issuable in connection with the LP Merger for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Combined Consent Statement/Prospectus or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any information relating to Parent or the Partnership, or any of their respective affiliates, officers or directors, is discovered by Parent or the Partnership that should be set forth in an amendment or supplement to any of the Form S-4 or the Combined Consent Statement/Prospectus, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the unitholders of the Partnership. For the avoidance of doubt, the Combined Consent Statement/Prospectus shall not be required to include a recommendation by the GP Board or the Conflicts Committee to the Partnership’s unitholders regarding this Agreement.

- 58 -

(b) The General Partner shall distribute to the Partnership’s unitholders the Combined Consent Statement/Prospectus as promptly as practicable after the Form S-4 is declared effective under the Securities Act. The Partnership shall (i) in accordance with the Partnership Organizational Documents, including Sections 13.6 and 13.11 of the Partnership Agreement, and applicable Law, take all actions to establish a record date (which will be as soon as reasonably practicable after the date upon which the Form S-4 is declared effective) for the purpose of determining Partnership unitholders entitled to deliver written consents, and (ii) in accordance with the Partnership Organizational Documents and applicable Law, distribute to the Partnership’s unitholders, the Combined Consent Statement/Prospectus, which shall include a form of consent that may be executed by the public unitholders of the Partnership Common Units in connection with the Requisite Unitholder Approval, as soon as reasonably practicable after the date upon which the Form S-4 becomes effective (and, in the case of the Sponsors, within 24 hours of the Form S-4 being declared effective).

Section 5.6 Equity-Based Awards.

(a) Each award of phantom units that corresponds to Partnership Common Units and vests solely based on the passage of time (including any Seconded Employee Phantom Awards), whether vested or unvested (“Partnership Phantom Units”), that is outstanding immediately prior to the Effective Time, shall, as of the Effective Time, be assumed by Parent and converted into a restricted unit award representing a contractual right to receive Parent Common Units or, in the case of Seconded Employees, the right to receive cash determined based on the value of Parent Common Units (each an “Assumed Restricted Unit Award”). Each such Assumed Restricted Unit Award shall be converted into a restricted unit award to receive a number of Parent Common Units (or the cash equivalent thereof, as applicable) equal to the product obtained by multiplying (x) the number of Partnership Common Units subject to such Partnership Phantom Unit immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up or down to the nearest whole Parent Common Unit. Each Assumed Restricted Unit Award shall otherwise be subject to the same terms and conditions (including as to vesting, distribution equivalent rights and issuance) as were applicable to the Partnership Phantom Unit immediately prior to the Effective Time.

(b) Each award of performance units that corresponds to Partnership Common Units, including Seconded Employee Performance Awards (each, a “Partnership Performance Award,” and together with the Partnership Phantom Units, the “Partnership Equity Awards”), that is outstanding and unvested as of the Effective Time, shall, as of the Effective Time, be measured as to performance as of the Effective Time (or a date reasonably proximate thereto) as determined in good faith by the GP Board and each such Partnership Performance Award shall, with respect to the number of Partnership Common Units that are considered earned with respect thereto based on the higher of actual performance or target shall, as of the Effective Time (the “Earned Performance Units”), be assumed by Parent and converted into an Assumed Restricted Unit Award, which shall have distribution equivalent rights and be eligible to vest solely based

- 59 -

on continued service at the end of the performance period that was originally applicable thereto; provided, however, that the Earned Performance Units will vest upon a “qualifying termination” and, to the extent applicable, will incorporate the provisions related to termination due to “retirement,” as provided in the Partnership Phantom Unit Awards. Notwithstanding the foregoing, with respect to Partnership Performance Awards granted in 2021, the number of Earned Performance Units shall be equal to the target number of units granted, regardless of performance. The number of Parent Common Units that are subject to such Assumed Restricted Unit Awards shall be equal to the number of Earned Performance Units with respect to the corresponding Partnership Performance Award, multiplied by the Exchange Ratio, rounded up or down to the nearest whole Parent Common Unit. Any performance units that correspond to Partnership Common Units that are not Earned Performance Units shall, upon the Effective Time, automatically be cancelled for no consideration.

(c) The General Partner shall take any and all actions reasonably necessary to effectuate the transactions contemplated by this Section 5.6 and such transactions shall be subject to compliance with Section 409A of the Code.

Section 5.7 Employee Matters.

(a) Following the Effective Time and until the first anniversary of the Closing Date (the “Continuation Period”), Parent shall, or shall cause one of its Subsidiaries to, provide the individuals who are employed by the Partnership, the General Partner or any of their Subsidiaries immediately before the Effective Time (the “Current Employees”) and who continue employment during such time period with (i) annual base salary or wages (as applicable) that are no less favorable than the annual base salary or wages (as applicable) provided to such Current Employees immediately prior to the Effective Time,(provided, that the foregoing shall not preclude Parent from implementing broad-based salary or other pay reduction programs following the date of this Agreement that are proportionate with reductions in salary or other pay for Parent’s other similarly situated employees), (ii) severance benefits that are no less favorable than the severance benefits set forth on Section 5.7(a) of the Partnership Disclosure Schedule, provided, however, that severance benefits for those certain employees subject to the Partnership’s February 2021 voluntary early retirement program (the “VERP”) and the other employees set forth on Section 5.7(a) of the Partnership Disclosure Schedule shall be as set forth in the VERP, and (iii) other compensation and employee benefits that are no less favorable than either, at Parent’s election, (A) the other compensation and employee benefits provided to similarly situated employees of Parent and its Subsidiaries, or (B) the other compensation and employee benefits provided to such Current Employees immediately prior to the Effective Time (excluding equity and equity-based compensation, defined benefit and supplemental pensions and retiree medical benefits).

(b) For purposes of vesting, eligibility to participate and, solely for vacation and paid time off policies, severance plans and policies, and disability plans and policies, determining levels of benefits (but not, for the avoidance of doubt, for purposes of benefit accrual under any defined benefit pension plan) under the employee benefit plans of Parent and its Subsidiaries providing benefits to any Current Employees after the Effective Time (the “New Plans”), each Current Employee shall be credited with his or her years of service with the Partnership, the General Partner and their Subsidiaries and their respective predecessors and

- 60 -

prior employers before the Effective Time, to the same extent as such Current Employee was entitled, before the Effective Time, to credit for such service under any similar Partnership Benefit Plan in which such Current Employee participated or was eligible to participate immediately prior to the Effective Time, provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits with respect to the same period of service. In addition, and without limiting the generality of the foregoing, (i) each Current Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is comparable to a Partnership Benefit Plan in which such Current Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Current Employee, Parent shall use commercially reasonable efforts to cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, unless and to the extent the individual, immediately prior to entry in the New Plans, was subject to the same such conditions under the comparable Old Plans, (iii) credit amounts paid under any Old Plan providing medical, dental, pharmaceutical and/or vision benefits under any corresponding New Plan for purposes of applying deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the New Plan with respect to the plan year in which the Effective Time occurs, and (iv) assume and honor all vacation and paid time off days accrued by Current Employees prior to the Effective Time, including payment for such days upon termination of employment to the extent provided for under Law or the terms of the vacation and paid time off policies of the Partnership, the General Partner and their Subsidiaries, provided however, that the foregoing shall not restrict Parent from amending, modifying or terminating any applicable vacation or paid time off policy to the extent permitted by Law and (v) solely for vacation and paid time off policies, provide credit for years in the energy industry in addition to prior service credit with the Partnership, the General Partner and their Subsidiaries and their respective predecessors before the Effective Time. For purposes of this Agreement, “Benefit Plans” means any (i) “employee benefit plan” (within the meaning of Section 3(3) of ERISA), (ii) bonus, incentive or deferred compensation or equity or equity-based compensation plan, program, policy or arrangement, including employer stock and incentive plans, (iii) severance, change in control, employment, consulting, retirement, retention or termination plan, program, agreement, policy or arrangement or (iv) other compensation or benefit plan, program, agreement, policy, practice, contract, arrangement or other obligation, whether or not in writing and whether or not subject to ERISA, including all bonus, cash or equity-based incentive, deferred compensation, stock purchase, health, medical, dental, disability, accident, life insurance, or vacation, paid time off, perquisite, fringe benefit, severance, change of control, retention, employment, separation, retirement, pension, or savings, plans, programs, policies, agreements or arrangements.

(c) If the Effective Time occurs after July 1, 2021, then as soon as practicable following the Closing Date, Parent shall pay annual incentive bonuses for the 2021 calendar year in an amount equal to the higher of actual performance or target, prorated for the portion of the 2021 calendar year that occurs prior to the Closing Date, under the Partnership Short Term Incentive Plan. If the Effective Time occurs before July 1, 2021, then no pro-rated annual incentive bonuses will be paid in connection with the consummation of the transactions contemplated by this Agreement and the Current Employees will be eligible for annual bonuses for 2021 under the terms of Parent’s applicable short-term incentive plans as if they had been employed with Parent and its Subsidiaries from January 1, 2021.

- 61 -

(d) Parent shall establish and maintain or make provision for, the establishment or continuation of a health care and dependent care flexible spending account plans applicable to Current Employees and the election by any Current Employee under the Partnership Benefit Plan that includes flexible spending accounts will be continued as an election as if made under the applicable Benefit Plan containing flexible spending accounts from the beginning of the plan year of Partnership.

(e) If the Effective Time occurs prior to the end of a school semester, Parent acknowledges that the Partnership, the General Partner or their applicable Subsidiary or applicable successor thereof shall retain their obligations with respect to the Partnership’s tuition reimbursement program for the remainder of that semester and shall provide benefits thereunder in accordance with terms of such program to eligible Current Employees immediately prior to the Effective Time.

(f) If requested by Parent, subject to the terms of any such Partnership Benefit Plan and applicable Law, the Partnership or General Partner, as applicable, shall both (i) execute resolutions to terminate any Partnership Benefit Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement (a “Partnership 401(k) Plan”) and (ii) fully vest each Current Employee in his or her account balance in such Partnership 401(k) Plan, in each case, effective at least one day prior to the Closing Date (the “ERISA Effective Date”). Prior to the ERISA Effective Date, the Partnership shall provide Parent with executed resolutions of its or, as applicable, its Subsidiary’s Board of Directors authorizing such termination and amending any such Partnership 401(k) Plan commensurate with its termination to the extent necessary to comply with all applicable Laws. The Partnership and the General Partner shall also take and/or cause their Subsidiaries to take such other actions in furtherance of the termination of each Partnership 401(k) Plan as Parent may reasonably require, including such actions as Parent may require prior to the Effective Time to support Parent obtaining a determination letter with respect to the termination of each Partnership 401(k) Plan following the ERISA Effective Date. Parent shall cause its Parent Benefit Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement to accept a direct rollover of any Current Employee’s benefits under the Partnership 401(k) Plan in cash and, if applicable, promissory notes.

(g) Parent acknowledges that the Partnership, the General Partner or their applicable Subsidiary or applicable successor thereof shall retain their obligations under the Partnership Deferred Compensation Plan and all duties and obligations thereunder. Parent will not cause the Partnership Deferred Compensation Plan to be terminated without payment of vested benefits accrued thereunder becoming payable to the participants therein.

(h) Parent hereby acknowledges that a “change of control” (or similar phrase) within the meaning of the Partnership Benefit Plans will occur at or prior to the Effective Time, as applicable. For the avoidance of doubt, Parent shall assume the Partnership Change of Control Plan and all duties and obligations of the Partnership thereunder. Parent will not terminate the Partnership Change of Control Plan prior to the end of the “Protected Period” as defined therein.

- 62 -

(i) Nothing in this Section 5.7 shall be construed as an amendment of, or undertaking to amend, any Benefit Plan or to prevent the amendment or termination of any Benefit Plan in accordance with its terms. Nothing in this Section 5.7 shall limit the right of Parent, the Surviving Entities or any of their Subsidiaries to terminate the employment of any Current Employee at any time, subject to any rights to severance or other separation benefits accrued as of the applicable termination date under a Partnership Benefit Plan. Without limiting the generality of Section 8.13, the provisions of this Section 5.7 (including, for the avoidance of doubt, Section 5.7(j)) are solely for the benefit of the parties to this Agreement, and no current or former director, officer, employee, other service provider or independent contractor or any other person shall be a third-party beneficiary of this Agreement, and nothing herein shall be construed as an amendment to any Partnership Benefit Plan or other compensation or benefit plan or arrangement (including any Benefit Plan of Parent or its Subsidiaries) for any purpose.

(j) Subject to Section 5.7(k) below, Parent, the Partnership and the General Partner shall reasonably cooperate to take such actions as are necessary or desirable to provide for the termination of all Secondment Arrangements, and shall use commercially reasonable efforts to enter into an agreement or agreements with Ox or its applicable affiliate pursuant to which (i) the Secondment Arrangements shall be terminated upon or as soon as reasonably practicable after the Effective Time such that, as of such time of termination, the Seconded Employees shall be eligible to participate in the Benefit Plans of Parent or its applicable Subsidiary(ies) (the actual time of such termination, the “Secondment Termination Time”), excluding those obligations which by the terms of the Secondment Arrangements are intended to survive any such termination; (ii) one of Parent, the Partnership, the General Partner, or an applicable Subsidiary or successor of the foregoing shall have made an offer of employment, effective upon the Secondment Termination Time, to each Seconded Employee with such offers of employment on terms consistent with the provisions of Sections 5.7(a)-(d) and (h) but applying Section 5.7(a)-(d) and (h) with respect to the Seconded Employees by taking into account the compensation and benefits provided to the Seconded Employees by Ox or its applicable affiliate, and the Seconded Employees’ service with Ox or its applicable affiliate as of, immediately prior to the Effective Time (excluding, for the avoidance of doubt, equity and equity-based compensation, defined benefit and supplemental pensions and retiree medical benefits); and (iii) the Termination Costs and Severance Costs (as defined in the applicable Secondment Arrangement) of each Seconded Employee who does not become a Current Employee, or for which a Sponsor is otherwise responsible in respect of any Seconded Employee under the terms of the applicable Secondment Arrangement, will remain the obligation of the Partnership, the General Partner or their applicable Subsidiary or successor to the extent such Termination Costs and Severance Costs are the obligation of the Partnership, the General Partner or their applicable Subsidiary or successor pursuant to the terms of the applicable Secondment Arrangement. For the avoidance of doubt, subject to Section 5.7(k) below, it is expected that all such Seconded Employees who accept such offers and commence employment with Parent, the Partnership, the General Partner, or an applicable Subsidiary or successor of the foregoing shall be considered Current Employees for purposes of this Section 5.7. From and after the date of this Agreement, the General Partner and the Partnership shall, and shall use commercially reasonable efforts to cause any person employing a Seconded Employee to, reasonably cooperate with

- 63 -

Parent and provide Parent with such information regarding the Seconded Employees as is reasonably requested by Parent, including compensation information. Section 5.7(j) of the Partnership Disclosure Schedule sets forth, to the knowledge of the Partnership, a true and correct list of each Benefit Plan or other agreement maintained, sponsored, or entered into by a Sponsor (or an Affiliate thereof) pursuant to which any Termination Costs and Severance Costs would be incurred with respect to any Seconded Employee.

(k) Inactive Seconded Employees. With respect to any Seconded Employee who, as of the Closing, is not actively in service and on a disability or other approved leave of absence (excluding bona fide vacation) (an “Inactive Seconded Employee”), Ox or its applicable affiliate shall employ or shall continue to employ such Inactive Seconded Employee following the Closing and the applicable Secondment Arrangement will remain in effect with respect to and will continue to cover such Inactive Seconded Employee until he or she returns to active service or terminates employment with Ox or its applicable affiliate, and Parent’s, the Partnership’s, the General Partnership’s, or their applicable Subsidiary’s offer of employment to such Inactive Seconded Employee shall be for employment on the earliest reasonably practicable date following the date on which such Inactive Seconded Employee is able to return to work, and otherwise on the terms and conditions consistent with this Section 5.7(k); provided that such Inactive Seconded Employee is able to return to work within 180 days following the Closing Date, or such later time as required by applicable Law. For all purposes of this Agreement, in the case of any Inactive Seconded Employee who becomes a Current Employee, the date that such Inactive Seconded Employee commences (or is deemed to commence) employment with Parent or its Subsidiaries or the time of such commencement (or deemed commencement) of employment shall be substituted for the “Secondment Termination Time,” wherever such term appears, except where the context requires otherwise.

Section 5.8 Regulatory Approvals; Efforts.

(a) Subject to the terms and conditions set forth in this Agreement, each of the parties hereto shall use (and shall cause its Subsidiaries and affiliates (other than Caribou and Ox and their respective affiliates (other than the Partnership and its Subsidiaries) to use) its reasonable best efforts to take, or cause to be taken, promptly all actions, and to do, or cause to be done, promptly and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable under applicable Laws to consummate and make effective the LP Merger and the other transactions contemplated by this Agreement, including using reasonable best efforts to: (i) obtain all necessary actions or nonactions, waivers, clearances, consents and approvals, including the Partnership Approvals and the Parent Approvals, from Governmental Entities and make all necessary registrations, notifications and filings and take other steps as may be necessary to obtain an action or nonaction, waiver, clearance, consent or approval from any Governmental Entity, in each case as promptly as commercially practicable, (ii) obtain all necessary consents, approvals or waivers from third parties other than any Governmental Entity, in each case as promptly as commercially practicable, and (iii) execute and deliver any additional instruments necessary to consummate the transactions contemplated by this Agreement.

Prior to transmitting any substantive communications, advocacy, white papers, information responses or other submissions to any Governmental Entity (or members of their respective staffs) in connection with the LP Merger or the other transactions contemplated by this Agreement, the Partnership and Parent shall permit counsel for the other parties a reasonable opportunity to review and provide comments thereon, and consider in good faith the views of the other parties in connection therewith. Each of the Partnership and Parent agrees not to participate in any substantive meeting or discussion, either in person or by telephone, with any Governmental Entity in connection with the LP Merger or the other transactions contemplated by this Agreement unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Entity, gives the other parties the opportunity to attend and participate where appropriate and advisable under the circumstances.

- 65 -

preliminary or permanent) that would prevent the Closing from occurring no later than the End Date; provided, however, that such litigation in no way limits the other obligations of the parties; provided, further, that notwithstanding anything to the contrary contained in this Section 5.8 or otherwise in this Agreement, Parent and its Subsidiaries and affiliates shall not be required to offer, negotiate, commit to, effect, enter into or take any action, agreement, condition, commitment or remedy of any kind, including but not limited to any sale, divestiture or disposition of any assets, properties or businesses of Parent, the Partnership or their respective Subsidiaries or affiliates that would require Parent or its Subsidiaries or affiliates to sell, divest, lease, license, transfer, dispose of, or otherwise encumber, impair, limit or restrict Parent’s or its Subsidiaries’ or affiliates’ ownership, control, management or operation of assets or businesses (including for the avoidance of doubt, any equity or other interests) of Parent, the Partnership or any of their respective Subsidiaries or affiliates (other than Caribou and Ox and their respective affiliates (other than the Partnership and its Subsidiaries)) meeting or exceeding the Remedy Threshold.

(g) The obligations of Parent and the Surviving Entities under this Section 5.11 shall not be terminated, amended or modified in any manner so as to adversely affect any Indemnified Party (including their successors, heirs and legal representatives) to whom this Section 5.11 applies without the consent of such Indemnified Party.

Parent shall indemnify and hold harmless the General Partner, the Partnership and its Subsidiaries from and against any and all claims, losses, or damages suffered or incurred by them directly or indirectly in connection with the arrangement of any such financing or any information provided in connection therewith (other than to the extent related to information provided by the General Partner, the Partnership, its Subsidiaries or their respective Representatives that contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading).

any of their respective Representatives pursuant to any agreement, arrangement, contract, certificate, instrument, or other document relating to any such financing will be effective until the Effective Time, and none of the General Partner, the Partnership, nor any of its Subsidiaries will be required to take any action pursuant to any of the foregoing that is not contingent on the occurrence of the Closing or that must be effective before the Effective Time. Further, nothing in this Section 5.16 will require (1) the General Partner, the Partnership, its Subsidiaries, or their respective Representatives to execute, deliver or enter into, or perform any agreement, document or instrument, including any definitive financing document, with respect to any financing or adopt resolutions approving the agreements, documents and/or instruments pursuant to which any financing is obtained or pledge any collateral with respect to any financing prior to Closing or (2) any officer or Representative of the General Partner, the Partnership or any of its Subsidiaries to deliver any certificate or take any other action under this Section 5.16 that could reasonably be expected to result in personal liability to such officer or Representative, or (3) the Representatives of the General Partner, the Partnership or its Subsidiaries to deliver any legal opinions with respect to such financing.

For the avoidance of doubt, any such redemption, prepayment or other payment made to satisfy and discharge or defease such portion of indebtedness for borrowed money of the Partnership or any of its Subsidiaries prior to or at Closing shall be the sole obligation of Parent, and all reasonable and documented out-of-pocket costs and expenses incurred by the Partnership or any of its Subsidiaries or their respective Representatives under this clause (d) shall be promptly reimbursed by Parent upon request. Parent shall prepare all necessary and appropriate documentation in connection with any action described above, and provide the Partnership, its Subsidiaries, and their respective Representatives with a reasonable opportunity and prior notice to comment on such documents.

- 77 -

of this Agreement and at and as of the Closing Date as though made at and as of the Closing Date, except for any immaterial inaccuracies, and (iii) Section 3.10(b) and Section 3.10(c) shall be true and correct both at and as of the date of this Agreement and at and as of the Closing Date as though made at and as of the Closing Date; provided, however, that representations and warranties that are made as of a particular date or period shall be true and correct (in the manner set forth in clauses (i), (ii) and (iii), as applicable) only as of such date or period;

ARTICLE VII.

TERMINATION

Section 7.1 Termination or Abandonment. Notwithstanding anything in this Agreement to the contrary, this Agreement may be terminated and abandoned at any time prior to the Effective Time:

(a) by the mutual written consent of the Partnership and Parent;

- 78 -

(b) by either the Partnership or Parent, if the LP Merger shall not have been consummated on or prior to November 30, 2021 (the “End Date”); provided, however, that if all of the conditions to Closing, other than any of the conditions set forth in Section 6.1(b) or Section 6.1(c), shall have been satisfied or shall be capable of being satisfied at such time, the End Date shall automatically be extended to February 28, 2022, which date shall thereafter be deemed to be the End Date; provided, further, that the right to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to a party if the failure of the Closing to occur by such date shall be due to the material breach by such party of any representation, warranty, covenant or other agreement of such party set forth in this Agreement;

(c) by either the Partnership or Parent, if an injunction or other Law shall have been entered, enacted or become effective permanently restraining, enjoining or otherwise prohibiting the consummation of the Mergers and such injunction or other Law has become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 7.1(c) shall not be available to a party if such injunction was due to the material breach by such party of any covenant or other agreement of such party set forth in this Agreement;

(d) by the Partnership, if Parent, Merger Sub or GP Merger Sub shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.2(a) or Section 6.2(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, Parent does not diligently attempt or ceases to diligently attempt to cure such breach or failure after receiving written notice from the Partnership describing such breach or failure in reasonable detail (provided that the Partnership is not then in material breach of any representation, warranty, covenant or other agreement contained herein);

(e) by Parent, if the Partnership or the General Partner shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.3(a) or Section 6.3(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, the Partnership or the General Partner, as applicable, does not diligently attempt, or ceases to diligently attempt, to cure such breach or failure in such a manner that would make it reasonably likely that such breach or failure will be cured prior to the End Date, in each case after receiving written notice from Parent describing such breach or failure in reasonable detail (provided that Parent is not then in material breach of any representation, warranty, covenant or other agreement contained herein); and

(f) by Parent, if the Partnership or the General Partner shall have Willfully Breached any of its obligations under Section 5.4, which materially impedes, interferes with or hinders the consummation of the transactions contemplated hereby on or before the End Date.

(b) If (i) this Agreement is terminated by Parent pursuant to Section 7.1(e) [Breach of Representation or Failure to Perform Covenant] and (ii) prior to such termination and after the date of this Agreement, any person (other than Parent, Merger Sub or any of their respective affiliates) shall have made an Acquisition Proposal, which shall have been publicly announced or disclosed or otherwise communicated to the GP Board or any affiliate of the General Partner (including Caribou and Ox but excluding their respective affiliates (other than the Partnership and its Subsidiaries)) and not have been withdrawn prior to such termination and (iii) within 12 months after the date of such termination, the Partnership enters into a definitive agreement with respect to an Acquisition Proposal (or publicly approves or recommends to the unitholders of the Partnership or otherwise does not oppose, in the case of a tender or exchange offer, an Acquisition Proposal) or consummates an Acquisition Proposal, then the Partnership shall pay to Parent, within three business days of the first to occur of the events described in clause (iii), the Breakup Fee , by wire transfer of same day federal funds to the account specified by Parent.

(c) Solely for purposes of this Section 7.3, “Acquisition Transaction” shall have the meaning ascribed thereto in Section 5.4(c)(i), except that all references to “25% or more” shall be changed to “more than 50%.”

(d) As used in this Agreement, “Breakup Fee” means $97,500,000.

Upon payment of the Breakup Fee to Parent pursuant to Section 7.3(a) or Section 7.3(b), no parties shall have any further liability with respect to this Agreement or the transactions contemplated hereby to the Partnership or its unitholders or Parent or its unitholders, as applicable; provided that nothing herein shall release any party from liability arising out of or the result of fraud. The parties acknowledge and agree that in no event shall the Partnership be required to pay the Breakup Fee, as applicable, on more than one occasion. In addition, the parties acknowledge that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement and are not a penalty, and that, without these agreements, neither party would enter into this Agreement. If the Partnership fails to pay promptly the amounts due pursuant to this Section 7.3, the Partnership will also pay to Parent interest on the unpaid amount under this Section 7.3, accruing from its due date, at an interest rate per annum equal to two percentage points in excess of the prime commercial lending rate quoted by The Wall Street Journal and the reasonable out-of-pocket expenses (including legal fees) in connection with any action taken to collect payment. Any change in the interest rate hereunder resulting from a change in such prime rate will be effective at the beginning of the date of such change in such prime rate.

REGISTRATION RIGHTS

Section 2.01    Shelf Registration.

(a)    As promptly as practicable after the date hereof, and in any event within five days following the date hereof, the Parent shall use commercially reasonable efforts to prepare and file a Registration Statement to permit the public resale of the Registrable Units held by the Holders from time to time as permitted by Rule 415 of the Securities Act (a “Shelf Registration Statement”) in accordance with the provisions of this Agreement; provided, that the Parent shall only be obligated to prepare and file one such Shelf Registration Statement pursuant to this Section 2.01 on behalf of the Holders. The Parent shall effect such Shelf Registration Statement using a registration statement on Form S-3 whenever the Parent is eligible to do so, and shall use an Automatic Shelf Registration Statement (as defined in Rule 405 of the Securities Act) if it is a well-known seasoned issuer (as defined under Rule 405 of the Securities Act). The Parent shall use its commercially reasonable efforts to (i) cause such Shelf Registration Statement to be declared effective as soon as practicable after the filing thereof and (ii) keep such Shelf Registration Statement continuously effective during the Effectiveness Period.

(b)    At any time and from time to time following the effectiveness of the Shelf Registration Statement required by Section 2.01(a), any Holder may request to sell all or a portion of their Registrable Units in an underwritten offering that is registered pursuant to such Shelf Registration Statement, including a Block Trade (a “Shelf Underwritten Offering”), provided that such Holder(s) reasonably expect(s) to sell Registrable Units yielding aggregate gross proceeds of at least $200,000,000 from such Shelf Underwritten Offering. All requests for a Shelf Underwritten Offering shall be made by giving written notice to the Parent (the “Shelf Takedown

4

Notice”). Each Shelf Takedown Notice shall specify the approximate number of Registrable Units proposed to be sold in the Shelf Underwritten Offering and the expected price range (net of underwriting discounts and commissions) of such Shelf Underwritten Offering. Within three Business Days after receipt of any Shelf Takedown Notice, the Parent shall give written notice of such requested Shelf Underwritten Offering to all other Holders of Registrable Units (the “Parent Shelf Takedown Notice”) and, subject to the provisions of Section 2.01(d), shall include in such Shelf Underwritten Offering all Registrable Units with respect to which the Parent has received written requests for inclusion therein within five Business Days after sending the Parent Shelf Takedown Notice, or, in the case of a Block Trade, as provided in Section 2.03. The Parent shall enter into an underwriting agreement in a form as is customary in underwritten offerings of securities by the Parent with the managing underwriter selected by the Holder(s) requesting such Shelf Underwritten Offering (which managing underwriter shall be subject to approval of the Parent, which approval shall not be unreasonably withheld) and shall take all such other reasonable actions as are requested by the managing underwriter in order to expedite or facilitate the disposition of such Registrable Units in accordance with the terms of this Agreement. In connection with any Shelf Underwritten Offering contemplated by this Section 2.01(b), subject to Section 2.04, the underwriting agreement into which each Holder and the Parent shall enter shall contain such representations, covenants, indemnities and other rights and obligations as are customary in underwritten offerings of securities by the Parent. Notwithstanding any other provision of this Agreement to the contrary, CenterPoint Energy, Inc. (“CenterPoint”) may not demand more than five Shelf Underwritten Offerings and OGE Energy Corp. (“OGE”) may not demand more than three Shelf Underwritten Offerings, provided that there shall be no more than three Shelf Underwritten Offerings in any 12-month period, of which, no more than two such Shelf Underwritten Offerings in any 12-month period may be demanded by CenterPoint and no more than one such Shelf Underwritten Offering in any 12-month period may be demanded by OGE unless either CenterPoint or OGE shall assign to the other one or more such Shelf Underwritten Offerings in any 12-month period.

(c)    If the Parent or any of its Affiliates is conducting or actively pursuing a securities offering of Parent Common Units (other than in connection with any at-the-market offering or similar continuous offering program), then the Parent may suspend any Holder’s right to require the Parent to conduct a Shelf Underwritten Offering pursuant to Section 2.01(b); provided, however, that the Parent may only suspend such Holder’s right to require the Partnership to conduct a Shelf Underwritten Offering once in any six-month period and in no event for a period that exceeds an aggregate of 60 days in any 180-day period or 90 days in any 365-day period.

(d)    In connection with any Shelf Underwritten Offering, if the managing underwriter advises the Parent that in its opinion the number of Registrable Units proposed to be included in such offering exceeds the maximum number of Parent Common Units that can be sold in such offering without being likely to materially delay or jeopardize the success or timing of the offering (including the price per unit of the Parent Common Units proposed to be sold in such offering), the Parent shall include in such Shelf Underwritten Offering the Registrable Units of the Holders pro rata based on the total amount of Registrable Units requested to be included therein by each such Holder that can be sold without exceeding such maximum number of Parent Common Units.

5

Section 2.02    Piggyback Registration.

(a)    If the Parent proposes to file with the SEC (i) a Registration Statement to register any Parent Common Units for an underwritten offering under the Securities Act or (ii) a prospectus supplement relating to the sale of Parent Common Units pursuant to an effective “automatic” registration statement, so long as the Parent is a WKSI at such time or, whether or not the Parent is a WKSI, so long as the Registrable Units were previously included in the underlying shelf Registration Statement or are included on an effective Registration Statement, in each case for its own account and/or for another Person (such other Person, an “Other Holder”), other than on a registration statement on Form S-8 or Form S-4, and the form of registration statement to be used may be used for a registration of Registrable Units (a “Piggyback Registration”), the Parent shall give five Business Days’ written notice to the Holders of its intention to file such registration statement and, subject to this Section 2.02, shall include in such Registration Statement and in any offering of Parent Common Units to be made pursuant to such Registration Statement all Registrable Units with respect to which the Parent has received a written request for inclusion therein from any Holder within three Business Days after such Holder’s receipt of the Parent’s notice. The Parent shall have no obligation to proceed with any Piggyback Registration and may abandon, terminate and/or withdraw such registration for any reason at any time prior to the pricing thereof. Any Holder shall have the right to withdraw such Holder’s request for inclusion of such Holder’s Registrable Units in such Piggyback Registration by giving written notice to the Parent of such withdrawal at least two Business Days prior to the time of the public announcement of the Parent’s intention to conduct such underwritten offering.

(b)    If a Piggyback Registration is initiated for an underwritten offering on behalf of the Parent or any Other Holder and the managing underwriter(s) advise the Parent that in their opinion the number of Parent Common Units proposed to be included in such offering exceeds the number of Parent Common Units that can be sold in such offering without being likely to materially delay or jeopardize the success or timing of the offering (including the price per unit of the Parent Common Units proposed to be sold in such offering), the Parent shall include in such registration and offering (i) first, the number of Parent Common Units that the Parent or, if such offering was initiated by any Other Holder, any Other Holder proposes to sell and (ii) second, the number of Parent Common Units requested to be included therein by the Holders that have elected to include Registrable Units in such Piggyback Registration, pro rata among all such Holders on the basis of the number of Parent Common Units requested to be included therein by all such Holders or as such Holders and the Parent may otherwise agree and (iii) third, the number of Parent Common Units requested to be included therein by other unitholders of Parent, pro rata among all such unitholders on the basis of the number of Parent Common Units requested to be included therein by all such unitholders or as such unitholders and the Parent may otherwise agree. If the number of Parent Common Units that can be so sold is less than the number of Parent Common Units proposed to be sold by the Parent or any Other Holder pursuant to the Piggyback Registration, the amount of Parent Common Units to be sold shall be fully allocated to the Parent or such Other Holder, as applicable.

(c)    In any Piggyback Registration under Section 2.02(b), the Parent shall have the right to select the underwriter or underwriters for any offering conducted pursuant thereto.

6

(d)    None of the Holders shall sell any Registrable Units in any offering pursuant to a Piggyback Registration unless it (i) agrees to sell such Registrable Units on the basis provided in the underwriting arrangements approved by the Parent and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, lockups and other documents reasonably required of such Holder under the terms of such arrangements.

Section 2.03     Block Trades. Notwithstanding the foregoing, at any time and from time to time when a Shelf Registration Statement is on file with the SEC and is effective, if a Holder wishes to engage in an underwritten or other coordinated registered offering not involving a “roadshow,” an offer commonly known as a “block trade” (a “Block Trade”), with a total offering price reasonably expected to be at least, in the aggregate, either (x) $50 million or (y) all remaining Registrable Units held by the Holder, then notwithstanding the time periods provided for in Section 2.01(b), such Holder need only to notify the Parent of the Block Trade at least five Business Days prior to the day such offering is to commence and the Parent shall use commercially reasonable efforts to facilitate such Block Trade; provided that the Holders representing a majority of the Registrable Units wishing to engage in the Block Trade shall use commercially reasonable efforts to work with the Parent and any underwriters prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Block Trade.

Section 2.04    Suspension Periods. The Parent may delay the filing or effectiveness of, or by written notice to the Holders suspend the use of, a Shelf Registration Statement in conjunction with a registration of Registrable Units pursuant to Section 2.01, but in each such case only if the Parent determines in good faith that (a) such delay would enable the Parent to avoid disclosure of material information, the disclosure of which at that time would be adverse to the Parent (including by interfering with, or jeopardizing the success of, any pending or proposed acquisition, disposition or reorganization), (b) such filing or use would render the Parent unable to comply with applicable securities Laws or (c) obtaining any financial statements (including required consents) required to be included in any such Shelf Registration Statement (or incorporated therein) would be impracticable. Any period during which the Parent has delayed the filing, effectiveness or use of a Registration Statement pursuant to this Section 2.04 is herein called a “Suspension Period.” During any such Suspension Period, the Holder will be entitled to withdraw any request for a Shelf Underwritten Offering and, if such request is withdrawn, such Shelf Underwritten Offering will not count as a Shelf Underwritten Offering. In no event shall the number of days covered by (i) any one Suspension Period exceed 60 days and (ii) all Suspension Periods in any 360 day period exceed 150 days. The Holders shall keep the existence of each Suspension Period confidential.

Section 2.05    Obligations of the Parent and the Holders. (a) Whenever required under Section 2.01 to use commercially reasonable efforts to effect the registration of any Registrable Units, the Parent shall:

(i)    as expeditiously as possible, subject to the other provisions of this Agreement, prepare and file with the SEC a Registration Statement with respect to such Registrable Units and cause such Registration Statement to be declared effective (or become automatically effective) under the Securities Act;

7

(ii)    use commercially reasonable efforts to prepare and file with the SEC such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to comply with the applicable requirements of the Securities Act and to keep such Registration Statement effective until the earliest date on which any of the following occurs: (A) all Registrable Units covered by such Registration Statement have been distributed in the manner set forth and as contemplated in such Registration Statement, (B) there are no longer any Registrable Units outstanding and (C) three years from the date such Registration Statement becomes effective (the “Effectiveness Period”);

(iii)    furnish to each selling Holder (A) as far in advance as reasonably practicable before filing a Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed, and provide each such Holder the opportunity to object to any information pertaining to such Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Holder with respect to such information prior to filing such Registration Statement or such other registration statement and the prospectus included therein or any supplement or amendment thereto, and (B) an electronic copy of such Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto in order to facilitate the public sale or other disposition of the Registrable Units covered by such Registration Statement or other registration statement;

(iv)    use commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement, or the lifting of any suspension of the qualification or exemption from qualification of any Registrable Units for sale in any jurisdiction in the United States;

(v)    if applicable, use commercially reasonable efforts to register or qualify such Registrable Units under such other securities or blue sky laws of such U.S. jurisdictions as the Holders reasonably request and continue such registration or qualification in effect in such jurisdictions for as long as the applicable Registration Statement may be required to be kept effective under this Agreement (provided, that the Parent will not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph (v), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction);

(vi)    the Parent shall ensure that a Registration Statement when it becomes or is declared effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (and, in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the effective date of a Registration Statement, but in any event within one Business Day of such date, the Parent will notify the selling Holders of the effectiveness of such Registration Statement;

8

(vii)    promptly notify the Holders, at any time when delivery of a Prospectus relating to its Registrable Units would be required under the Securities Act, of (A) the occurrence of any event as a result of which the Prospectus included in such Registration Statement contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and prepare, as soon as practical, a supplement or amendment to such Prospectus so that, as thereafter delivered to any prospective purchasers of such Registrable Units, such Prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; (B) the Parent’s receipt of any written comments from the SEC with respect to any filing referred to in clause (A) and any written request by the SEC for amendments or supplements to such Registration Statement or any other registration statement or any Prospectus thereto, the issuance or threat of issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose, and (C) the receipt by the Parent of any notification with respect to the suspension of the qualification of any Registrable Units for sale under the applicable securities or blue sky laws of any jurisdiction. The Parent agrees to as promptly as practicable amend or supplement the Prospectus or take other appropriate action so that the Prospectus does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(c)    The Holders agree by having their Parent Common Units treated as Registrable Units hereunder that, upon being advised in writing by the Parent of the occurrence of an event pursuant to Section 2.05(a)(vii) when the Parent is entitled to do so pursuant to Section 2.04, the Holders will immediately discontinue (and direct any other Persons making offers and sales of Registrable Units to immediately discontinue) offers and sales of Registrable Units pursuant to any Registration Statement until it is advised in writing by the Parent that the use of the Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as contemplated by Section 2.05(a)(vii), and, if so directed by the Parent, the Holders will deliver to the Parent all copies, other than permanent file copies then in the Holders’ possession, of the Prospectus covering such Registrable Units current at the time of receipt of such notice.

10

In connection with an underwritten offering conducted pursuant to a registration effected hereunder, the participating Holders shall indemnify each participating underwriter to the same extent as provided above with respect to the indemnification of the Parent.

(b)    Any Person entitled to indemnification hereunder shall (1) give prompt written notice to the indemnifying Person of any claim with respect to which it seeks indemnification and (2) permit such indemnifying Person to assume the defense of such claim with counsel reasonably satisfactory to the indemnified Person. Failure to so notify the indemnifying Person shall not relieve it from any liability that it may have to an indemnified Person. The indemnifying Person shall not be subject to any liability for any settlement made by the indemnified Person without its consent (but such consent will not be unreasonably withheld). An indemnifying Person who is entitled to, and elects to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to one local counsel) for all Persons indemnified (hereunder or otherwise) by such indemnifying Person with respect to such claim (and all other claims arising out of the same circumstances), unless in the reasonable judgment of any indemnified Person there may be one or more legal or equitable defenses available to such indemnified Person that are in addition to or may conflict with those available to another indemnified Person with respect to such claim, in which case each such indemnified Person shall be entitled to use separate counsel. The indemnifying Person shall not consent to the entry of any judgment or enter into or agree to any settlement relating to a claim or action for which any indemnified Person would be entitled to indemnification by any indemnified Person hereunder unless such judgment or settlement imposes no ongoing obligations on any such indemnified Person and includes as an unconditional term the giving, by all relevant claimants and plaintiffs to such indemnified Person, of a release, reasonably satisfactory in form and substance to such indemnified Person, from all liabilities in respect of such claim or action for which such indemnified Person would be entitled to such indemnification.

(c)    The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person or any officer or director of such indemnified Person and shall survive the transfer of securities and the termination of this Agreement, but only with respect to offers and sales of Registrable Units made before such termination.

12

(d)    If the indemnification provided for in or pursuant to this Section 2.08 is due in accordance with the terms hereof, but is held by a court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying Person, in lieu of indemnifying such indemnified Person, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying Person, on the one hand, and of the indemnified Person, on the other hand, in connection with the statements or omissions which result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying Person, on the one hand, and of the indemnified Person, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying Person or by the indemnified Person, and by such Person’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

Section 2.09    Lockup. The Holders shall, in connection with any underwritten offering of Parent Common Units, upon the request of the underwriters managing the underwritten offering of Parent Common Units, agree in writing not to effect any sale, disposition or distribution of any Registrable Units (other than that included in such Registration) without the prior written consent of the underwriters for such period of time as such underwriters may specify, but in no event to exceed 10 days prior to the date of the Prospectus and 60 days from the date of the Prospectus.

Section 6.14    Severability. To the fullest extent permitted by law, any term or provision of this Agreement, or the application thereof, that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is illegal, void, invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any illegal, void, invalid or unenforceable term or provision with a term or provision that is legal, valid and enforceable and that comes closest to expressing the intention of the illegal, void, invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. To the fullest extent permitted by law, in the event such court does not exercise the power granted to it in the prior sentence, the parties hereto shall replace such illegal, void, invalid or unenforceable term or provision with a legal, valid and enforceable term or provision that will achieve, to the extent possible, the original economic, business and other purposes of such illegal, void, invalid or unenforceable term as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 6.15    Expenses. Except as otherwise expressly provided herein or in the Merger Agreement, all costs and expenses incurred in connection with this Agreement and the actions contemplated hereby shall be paid by the party incurring such expenses, whether or not the Mergers are consummated.

and obligations under this Agreement, in whole or in part or from time to time in part, to one or more of their affiliates to which their rights are assigned pursuant to the terms of the Merger Agreement at any time. Any assignment in violation of the foregoing shall be null and void. Subject to the preceding two sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

(b)    This Agreement is not intended to and shall not confer upon any person (other than the parties hereto) any rights or remedies hereunder.

Section 6.8    Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.

(a)    THIS AGREEMENT AND THE AGREEMENTS, INSTRUMENTS AND DOCUMENTS CONTEMPLATED HEREBY AND ALL DISPUTES BETWEEN THE PARTIES UNDER OR RELATING TO THIS AGREEMENT OR THE FACTS AND CIRCUMSTANCES LEADING TO ITS EXECUTION, WHETHER IN CONTRACT, TORT OR OTHERWISE, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH

9

THE LAWS OF THE STATE OF DELAWARE (WITHOUT REFERENCE TO SUCH STATE’S PRINCIPLES OF CONFLICTS OF LAW). THE DELAWARE COURT OF CHANCERY (AND IF THE DELAWARE COURT OF CHANCERY SHALL BE UNAVAILABLE, ANY DELAWARE STATE COURT AND THE FEDERAL COURT OF THE UNITED STATES OF AMERICA SITTING IN THE STATE OF DELAWARE) WILL HAVE EXCLUSIVE JURISDICTION OVER ANY AND ALL DISPUTES BETWEEN THE PARTIES HERETO, WHETHER IN LAW OR EQUITY, BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE AGREEMENTS, INSTRUMENTS AND DOCUMENTS CONTEMPLATED HEREBY OR THE FACTS AND CIRCUMSTANCES LEADING TO ITS EXECUTION, WHETHER IN CONTRACT, TORT OR OTHERWISE. EACH OF THE PARTIES IRREVOCABLY CONSENTS TO AND AGREES TO SUBMIT TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS IN ANY SUCH DISPUTE, IRREVOCABLY CONSENTS TO THE SERVICE OF THE SUMMONS AND COMPLAINT AND ANY OTHER PROCESS IN ANY OTHER ACTION OR PROCEEDING RELATING TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, ON BEHALF OF ITSELF OR ITS PROPERTY, BY DELIVERY IN ANY METHOD CONTEMPLATED BY SECTION 6.4 OR IN ANY OTHER MANNER AUTHORIZED BY LAW, AND HEREBY WAIVES, AND AGREES NOT TO ASSERT IN ANY SUCH DISPUTE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY CLAIM THAT (i) SUCH PARTY IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF SUCH COURTS, (ii) SUCH PARTY AND SUCH PARTY’S PROPERTY IS IMMUNE FROM ANY LEGAL PROCESS ISSUED BY SUCH COURTS OR (iii) ANY LITIGATION COMMENCED IN SUCH COURTS IS BROUGHT IN AN INCONVENIENT FORUM.

(b)    THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT THAT ANY PARTY MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY PROCEEDING, LITIGATION OR COUNTERCLAIM BASED ON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY.

Section 6.9    Amendment; Waiver. This Agreement may not be amended or modified, except by an instrument in writing signed on behalf of each of the parties hereto; provided, further, that no provision of this Agreement may be amended or waived without the prior consent of the Conflicts Committee (which consent, subject to the Conflicts Committee’s duties under applicable Law and the Partnership Agreement, shall not be unreasonably withheld, delayed or conditioned). Each party may waive any right of such party hereunder by an instrument in writing signed by such party and delivered to the party benefiting from such waiver.

Section 6.10    Amendment and/or Waiver of Merger Agreement. The parties hereto agree that neither the Parent Parties nor the Partnership Parties will agree to (i) amend or modify the Merger Agreement in any way that materially adversely affects the Unitholder unless the Unitholder consents in writing to such amendment or modification, or (ii) waive any right of such party under the Merger Agreement in any way that materially adversely affects the Unitholder unless the Unitholder consents in writing to such waiver. For the avoidance of doubt, the parties agree that without limiting the prior sentence, any amendment or modification of, or the waiver of rights under, Sections 2.1(a), 2.1(b), 5.1(b)(but only if such amendment or modification further

10

restricts the conduct of the Partnership or its Subsidiaries business), 5.8, 5.11, 5.14, 5.18, 6.1, 6.2, 7.1, 7.2, 7.3, 8.13 or 8.14 of the Merger Agreement shall be deemed to materially adversely affect the Unitholder.

Section 6.11    Remedies. The parties hereto agree that money damages would not be a sufficient remedy for any breach of this Agreement and that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is hereby agreed that, prior to the valid termination of this Agreement pursuant to Section 6.1, the parties hereto shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach, to prevent breaches of this Agreement, and to specifically enforce compliance with this Agreement. In connection with any request for specific performance or equitable relief, each of the parties hereto hereby waives any requirement for the security or posting of any bond in connection with such remedy. Such remedy shall not be deemed to be the exclusive remedy for breach of this Agreement but shall be in addition to all other remedies available at law or equity to such party. The parties further agree that, by seeking the remedies provided for in this Section 6.11, no party hereto shall in any respect waive its right to seek any other form of relief that may be available to it (i) under this Agreement, including monetary damages in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 6.11 are not available or otherwise are not granted, or (ii) under the Merger Agreement.

Section 6.12    Unitholder Capacity. Notwithstanding anything contained in this Agreement to the contrary, the representations, warranties, covenants and agreements made herein by the Unitholder are made solely with respect to such Unitholder and the Covered Units and the GP LLC Interests. The Unitholder is entering into this Agreement solely in its capacity as the owner, directly or indirectly, of such Covered Units and GP LLC Interests and nothing herein shall (a) limit or affect any actions or omissions by the Unitholder in any other capacity, (b) be construed to prohibit, limit or restrict any actions or omissions by any affiliate or direct or indirect owner of the Unitholder, or any of its or their respective officers, directors, managers, representatives or employees, in each case, not acting as such on behalf of the Unitholder, including exercising rights under the Merger Agreement or (c) be construed to prohibit, limit or restrict any of the Unitholder’s direct or indirect owners or affiliates, or any of its or their respective officers, directors, managers, representatives or employees, from exercising its fiduciary duties, if any, to the limited partners of the Partnership under applicable Law.

Section 6.13    Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, trustee, beneficiary, settlor, agent, attorney, representative or affiliate of the Unitholder shall have any liability (whether in contract or in tort) for any obligations or liabilities of the Unitholder arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby; provided that notwithstanding the foregoing the Unitholder shall remain responsible for all obligations or liabilities of the Unitholder arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby.

Section 6.14    Severability. To the fullest extent permitted by law, any term or provision of this Agreement, or the application thereof, that is invalid or unenforceable in any situation in

11

any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is illegal, void, invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any illegal, void, invalid or unenforceable term or provision with a term or provision that is legal, valid and enforceable and that comes closest to expressing the intention of the illegal, void, invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. To the fullest extent permitted by law, in the event such court does not exercise the power granted to it in the prior sentence, the parties hereto shall replace such illegal, void, invalid or unenforceable term or provision with a legal, valid and enforceable term or provision that will achieve, to the extent possible, the original economic, business and other purposes of such illegal, void, invalid or unenforceable term as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 6.15    Expenses. Except as otherwise expressly provided herein or in the Merger Agreement, all costs and expenses incurred in connection with this Agreement and the actions contemplated hereby shall be paid by the party incurring such expenses, whether or not the Mergers are consummated.

Section 6.16    Successors and Assigns; Third Party Beneficiaries.

(a)    Except in connection with a Permitted Transfer, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties hereto; provided, however, that Parent, Merger Sub and GP Merger Sub may transfer or assign their rights and obligations under this Agreement, in whole or in part or from time to time in part, to one or more of their affiliates to which their rights are assigned pursuant to the terms of the Merger Agreement at any time. Any assignment in violation of the foregoing shall be null and void. Subject to the preceding two sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

(b)    This Agreement is not intended to and shall not confer upon any person (other than the parties hereto) any rights or remedies hereunder.
