(b)Equity of Merger Sub. The limited liability company interests in Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into a number of Common Units of the Surviving Entity equal to the number of Public Common Units Canceled in exchange for the right to receive the Merger Consideration pursuant to Section 3.1(a).

(c)Treatment of Partnership Owned Units and Parent Owned Partnership Interests.

(i)Any Partnership Interests that are owned immediately prior to the Effective Time by the Partnership or any Subsidiary of the Partnership shall be automatically canceled at the Effective Time and shall cease to exist. No consideration will be delivered in exchange for such cancellation.

(ii)The Partnership Interests, including the General Partner Interest and the Incentive Distribution Rights, that are owned immediately prior to the Effective Time by Parent or any Subsidiary of Parent, including Holdings and Amoco, shall not be canceled, shall not entitle the holder thereof to receive the Merger Consideration, and shall remain outstanding as Partnership Interests in the Surviving Entity.

(d)Books and Records of the Partnership. The books and records of the Partnership shall be revised to reflect (i) the Cancellation of all Public Common Units and the right to receive the Merger Consideration in accordance with Section 3.1 and Section 3.2, (ii) the conversion of the limited liability company interests in Merger Sub in accordance with Section 3.1(b) and (iii) the cancellation of any Partnership Interests that are owned by the Partnership or any Subsidiary of the Partnership in accordance with Section 3.1(c)(i).

All Public Common Units Canceled in exchange for the right to receive the Merger Consideration as a result of and pursuant to the Merger pursuant to Section 3.1(a) will cease to be Outstanding (as such term is defined in the Partnership Agreement). At the Effective Time, each holder of a certificate that immediately prior to the Effective Time represented Public Common Units (a “Certificate”) and each holder of non-certificated Public Common Units represented by book-entry immediately prior to the Effective Time (“Book-Entry Units”) will cease to have any rights

with respect thereto or thereunder, except the right to receive (a) the Merger Consideration, (b) any dividend or distribution in accordance with Section 3.3(c), in each case to be issued or paid, without interest, in consideration therefor upon surrender of such Certificate or Book-Entry Units in accordance with Section 3.3, and (c) any distribution in respect of the Common Units with a record date occurring prior to the Effective Time that may have been declared by the Partnership on the Common Units in accordance with the terms of this Agreement and the Partnership Agreement and which remains unpaid at the Effective Time. At the Effective Time, the transfer books of the Partnership will be closed immediately and there will be no further registration of transfers on the transfer books of the Partnership with respect to Common Units.

Section 3.3Exchange of Certificates and Book-Entry Units.

(a)Exchange Agent. Prior to the Effective Time, Parent will appoint an exchange and payment agent hereunder reasonably acceptable to the Partnership for the purpose of exchanging Public Common Units for the Merger Consideration as required by this Article III (the “Exchange Agent”). As of the Effective Time, in consideration of the Cancellation and the issuance to Parent by its wholly owned direct Subsidiary, BP Holdings North America Ltd. (“BPHNAL”), of the BPHNAL Shares in accordance with and pursuant to the Intra-Group Agreement, Parent shall allot and deposit under the Deposit Agreement such number of Parent Ordinary Shares required to represent the Parent ADSs issuable pursuant to Section 3.1(a). Promptly after the Effective Time but on the Closing Date, Parent will deposit, or cause to be deposited, with the Exchange Agent for the benefit of the holders of the applicable Public Common Units, for exchange in accordance with this Article III, through the Exchange Agent, American depositary receipts evidencing (or evidence of Parent ADSs in book-entry form representing) the Parent ADSs issuable under this Article III in exchange for Public Common Units. Parent agrees to make available, or cause to be made available, to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends or other distributions pursuant to Section 3.3(c), without interest. Any dividends or other distributions with respect to Parent ADSs pursuant to Section 3.3(c) and evidence of Parent ADSs in book-entry form for payment of the Merger Consideration deposited with the Exchange Agent are hereinafter referred to as the “Exchange Fund.” The Exchange Agent will, pursuant to irrevocable instructions from Parent and the Partnership, deliver the Merger Consideration contemplated to be issued or paid pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Section 3.3(b) and Section 3.3(c), the Exchange Fund will not be used for any other purpose.

(b)Exchange Procedures. Promptly after the Effective Time, Parent will instruct the Exchange Agent to mail to each record holder of Public Common Units as of the Effective Time (i) a letter of transmittal (specifying that in respect of certificated Public Common Units, delivery will be effected, and risk of loss and title to the Certificates will pass, only upon proper delivery of the Certificates to the Exchange Agent, and which will be in customary form and agreed to by Parent and the Partnership prior to the Effective Time) and (ii) instructions (in customary form and agreed to by Parent and the Partnership prior to the Effective Time) for use in effecting the surrender of the Certificates or Book-Entry Units in exchange for the Merger Consideration payable in respect of Public Common Units represented by such Certificates or Book-Entry Units, as applicable. Promptly after the Effective Time, upon surrender of Certificates, if any, for cancellation to the Exchange Agent together with such letters of transmittal, properly completed and duly executed, and such other documents (including in respect of Book-Entry Units) as may be reasonably required pursuant to such instructions, each holder who held Public Common Units immediately prior to the Effective Time will be entitled to receive upon surrender of the Certificates or Book-Entry Units therefor (subject to any applicable withholding Tax) (A) Parent ADSs representing, in the aggregate, the whole number of Parent ADSs that such holder has the right to receive pursuant to this Article III (after taking into account all Public Common Units then held by such holder) and (B) a check in an amount equal to the aggregate amount of cash that such holder has the right to receive pursuant to this

Article III, including dividends or other distributions pursuant to Section 3.3(c). No interest will be paid or accrued on any dividends or other distributions payable pursuant to Section 3.3(c). In the event of a transfer of ownership of Public Common Units that is not registered in the transfer records of the Partnership, the Merger Consideration payable in respect of such Public Common Units may be paid to a transferee if the Certificate representing such Public Common Units or evidence of ownership of the Book-Entry Units is presented to the Exchange Agent, and in the case of both certificated and book-entry Public Common Units, accompanied by all documents reasonably required to evidence and effect such transfer, and the Person requesting such exchange will pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the record holder of such Public Common Units, or will establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable. Until all such required documentation has been delivered and Certificates, if any, have been surrendered as contemplated by this Section 3.3(b), each Certificate or Book-Entry Unit will be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration upon such delivery and surrender, and any cash or dividends or other distributions to which such holder is entitled pursuant to Section 3.3(c), if any.

(c)Distributions with Respect to Unexchanged Public Common Units. No dividends or other distributions with respect to Parent ADSs issued in the Merger shall be paid to the holder of any unsurrendered Certificates or Book-Entry Units until such Certificates or Book-Entry Units are surrendered as provided in this Section 3.3. Following such surrender, subject to the effect of escheat, Tax or other applicable Laws, there shall be paid, without interest, to the record holder of the Parent ADSs issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of any such Parent ADSs with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such Parent ADSs with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of Parent ADSs, all Parent ADSs to be issued pursuant to the Merger shall be entitled to dividends and other distributions pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

(d)No Fractional Parent ADSs. No certificates or scrip for Parent ADSs representing fractional Parent ADSs or book entry credit of the same will be issued upon the surrender of Public Common Units outstanding immediately prior to the Effective Time in accordance with Section 3.3(b), and such fractional interests will not entitle the owner thereof to vote or to have any rights as a holder of any Parent ADSs. Notwithstanding any other provision of this Agreement, in lieu of receiving any fraction of a Parent ADS, all fractions of Parent ADSs to which a holder of Public Common Units received the right to receive the Merger Consideration in the Merger would otherwise have been entitled shall be aggregated and the resulting fraction of a Parent ADS will be rounded up to a whole Parent ADS.

(e)No Further Rights in Public Common Units. The Merger Consideration issued upon conversion and Cancellation of a Public Common Unit in accordance with the terms hereof will be deemed to have been issued and paid in full satisfaction of all rights pertaining to such Public Common Unit (other than any distribution in respect of the Common Units with a record date occurring prior to the Effective Time that may have been declared by the Partnership on the Common Units in accordance with the terms of this Agreement and the Partnership Agreement and which remains unpaid at the Effective Time).

(f)Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Public Common Units on the one year anniversary of the Effective Time will be delivered to Parent upon demand by Parent and, from and after such

delivery, any former holders of Public Common Units who have not theretofore complied with this Article III will thereafter look only to Parent for the Merger Consideration payable in respect of such Public Common Units or any dividends or other distributions with respect to Parent ADSs to which they are entitled pursuant to Section 3.1 or Section 3.3(c), respectively, in each case, without any interest thereon. Any amounts remaining unclaimed by holders of Public Common Units immediately prior to such time as such amounts would otherwise escheat to or become the property of any Governmental Authority will, to the extent permitted by applicable Law, become the property of Parent. Without limitation of the foregoing, after the date that is the one year anniversary of the Effective Time, any amounts remaining unclaimed by holders of Public Common Units will become the property of Parent, subject to the legitimate claims of any Person previously entitled thereto hereunder or under abandoned property, escheat or similar Laws. Notwithstanding anything in this Agreement to the contrary, none of Parent, Holdings, the Partnership, Merger Sub, the Surviving Entity, the General Partner, the Exchange Agent, or any other Person shall be liable to any former holder of Public Common Units for any amount properly delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(g)Lost, Stolen or Destroyed Certificates. If any Certificate is lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of an indemnity agreement or a bond, in a customary amount, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate and affidavit the Merger Consideration payable in respect of Public Common Units represented by such Certificate as contemplated by this Article III and pay any dividends and other distributions pursuant to Section 3.3(c).

(h)Withholding Taxes. Each of Parent, Holdings, Merger Sub, the Surviving Entity and the Exchange Agent, as applicable, are entitled to deduct and withhold from any amounts, including the Merger Consideration, payable pursuant to this Agreement to any Person such amounts as Parent, Holdings, Merger Sub, the Surviving Entity or the Exchange Agent, as applicable, reasonably deems it is required to deduct and withhold under the Code or any provision of state, local, or foreign Tax Law, with respect to the making of such payment. Such deduction and withholding may be taken in securities, in which case Parent, Holdings, Merger Sub, the Surviving Entity or the Exchange Agent, as applicable, shall be treated as having sold such securities for an amount of cash equal to the fair market value of such securities at the time of such deemed sale. To the extent that deducted and withheld amounts (including deemed proceeds from the deemed sale of securities) are paid over to the appropriate Governmental Authority, such amounts (including securities) will be treated for all purposes of this Agreement as having been paid or issued to the Person in respect of whom such deduction and withholding was made.

(i)Book Entry Shares. All Parent ADSs to be issued in the Merger will be issued in book-entry form, without physical certificates.

Section 3.4No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

Section 3.5Anti-Dilution Provisions. Notwithstanding any provision of this Article III to the contrary, if between the date of this Agreement and the Effective Time the number of outstanding Common Units, Parent ADSs or Parent Ordinary Shares shall have been changed into a different number of units or shares or a different class or series by reason of any subdivisions, reclassifications, splits, share distributions, combinations or exchanges of Common Units, Parent ADSs or Parent Ordinary Shares, as applicable, then the Merger Consideration, the Exchange Ratio and any other similar dependent item, as applicable, will be correspondingly

adjusted to provide to the holders of Public Common Units the same economic effect as contemplated by this Agreement prior to such event; provided, however, that nothing in this Section 3.5 shall be deemed to permit or authorize any party hereto to effect any such change that it is not otherwise authorized or permitted to be undertaken pursuant to this Agreement.

Section 3.6Treatment of Awards. Prior to the Effective Time, Parent, the General Partner and the Partnership shall take all action as may be necessary or required in accordance with applicable Law and the Partnership Long-Term Incentive Plan (including the award agreements in respect of awards granted thereunder) to give effect to this Section 3.6 as follows: as of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Partnership LTIP Award that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any such Partnership LTIP Awards, cease to relate to or represent a right with respect to Common Units and shall be converted into the right to receive the Merger Consideration, except that the number of the Parent ADSs issued shall be equal to the number of Common Units subject to the corresponding Partnership LTIP Award multiplied by the Exchange Ratio, rounded up to the nearest whole unit. The Parent ADSs issued as the Merger Consideration will be subject to adjustment in accordance with Section 3.5, and will be duly authorized, validly issued, fully paid and non-assessable in accordance with applicable Laws. With respect to each Partnership LTIP Award, any distribution or distribution equivalent amounts accrued but unpaid as of the Closing will be paid to the holder within 30 days of the Closing.

Section 6.3Reasonable Best Efforts. Subject to the terms and conditions of this Agreement, Parent, Holdings and Merger Sub, on the one hand, and the Partnership and the General Partner, on the other hand, shall cooperate with the other and use and shall cause their respective Subsidiaries to use their reasonable best efforts to (i) take, or cause to be taken, all appropriate actions, and do, or cause to be done, all things, necessary, proper or advisable to cause the conditions to the Closing to be satisfied as promptly as reasonably practicable, including, for the avoidance of doubt, in the case of Parent, Holdings and the General Partner, until the Effective Time or the termination of this Agreement, retaining ownership and voting control, directly or indirectly, over all Common Units and the General Partner Interest in the Partnership beneficially owned by Parent, Holdings, any of their respective Subsidiaries or the General Partner, as applicable, as of the date of this Agreement or acquired thereafter, and to consummate and make effective the transactions contemplated by this Agreement, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, notifications, notices, petitions, statements, registrations, submissions of information, applications and other documents, (ii) promptly obtain all approvals, consents, waivers, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations from any Governmental Authority or third party necessary, proper or advisable to consummate the transactions contemplated by this Agreement, and (iii) defend any Proceedings challenging this Agreement or the consummation of the transactions contemplated by this Agreement or seek to have lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby.

Section 6.4Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by Parent and the Partnership. Thereafter, neither Parent nor the Partnership shall issue or cause the publication of any press release or other public announcement (to the extent not previously issued or made in accordance with this Agreement) with respect to this Agreement or the transactions contemplated by this Agreement without the prior consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except as may be required by applicable Laws or by any applicable listing agreement with the NYSE or the LSE, as applicable, as determined in the good faith judgment of the party proposing to make such release (in which case such party shall not issue or cause the publication of such press release or other public announcement without prior consultation with the other party); provided, however, that each party and their respective Affiliates may make statements that are consistent with statements made in previous press releases, public disclosures or public statements made by Parent or the Partnership in compliance with this Section 6.4.

Section 6.5Access to Information.

(a)Upon reasonable advance notice and subject to applicable Laws relating to the exchange of information, the Partnership shall, and shall cause each of its Subsidiaries to, afford to Parent and its Representatives, reasonable access during normal business hours (and, with respect to books and records, the right to copy) to all of its and such Subsidiaries’ properties, commitments, books, Contracts, records and correspondence (in each case, whether in physical or electronic form), officers, employees, accountants, counsel, financial advisors and other Representatives, in each case for integration and operational planning related to the transactions contemplated by this Agreement; provided, that such access shall be provided on a basis that minimizes the disruption to the operations of the requested party and its Representatives.

(b)Subject to applicable Laws, from the date of this Agreement until the Effective Time, Parent and the Partnership shall furnish promptly to one another (i) a copy of each report, schedule, registration statement and other document filed, published, announced or received by it in connection with the transactions contemplated by this Agreement during such period pursuant to the requirements of federal, state or foreign Laws (including pursuant to the Securities Act, the Exchange Act and the rules of any Governmental Authority thereunder), as applicable (other than documents that such party is not permitted to disclose under applicable Laws) (which such furnishing will be deemed to have occurred in the case of any document filed with or furnished to the SEC without further action on the part of the furnishing party) and (ii) evidence of approval of each Listing Application.

(c)Each party shall furnish promptly to the other party all information concerning such party’s relevant business, properties and personnel as the other party may reasonably request (including with respect to the scope and basis of such request) for the purpose of confirming that the representations and warranties of such party contained herein are true and correct and that the covenants of such party contained herein have been performed in all material respects. Notwithstanding the foregoing, no party shall be obligated to provide the other party access to any information the disclosure of which such party has concluded, in its reasonable judgment, may (i) jeopardize the protection of an attorney-client privilege, attorney work product protection or other legal privilege available to such party or any of its Affiliates relating to such information or (ii) would be in violation of a confidentiality obligation to a third party binding on such party or any of its Subsidiaries.

Section 6.6Indemnification and Insurance.

(a)From and after the Effective Time, to the fullest extent permitted under applicable Laws, Parent shall cause the Surviving Entity to (i) indemnify and hold harmless each Indemnified Person against any reasonable costs or expenses (including reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Proceeding arising out of, relating to or in connection with their status or duties as an Indemnified Person, any act or omission by them in their capacities as such occurring or alleged to have occurred at or prior to the Effective Time or any other matter existing at or prior to the Effective Time relating to or that may involve their status or duties as an Indemnified Person (including this Agreement and the transactions and actions contemplated hereby), including any such Proceeding relating to a claim for indemnification or advancement brought by an Indemnified Person), judgments, fines, losses, claims, damages or liabilities, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) in

connection with any such actual or threatened Proceeding, and, upon receipt by Surviving Entity of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall be determined in a final and non-appealable judgment entered by a court of competent jurisdiction that the Indemnified Person is not entitled to be indemnified, provide advancement of expenses with respect to each of the foregoing to, all Indemnified Persons and (ii) honor the provisions regarding elimination of liability of officers and directors, indemnification of officers, directors and employees and advancement of expenses contained in the Organizational Documents of the Partnership and the General Partner immediately prior to the Effective Time, and ensure that the Organizational Documents of the Partnership and the General Partner or any of their respective successors or assigns, if applicable, shall, for a period of six years following the Effective Time, contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors, officers and employees of the Partnership and the General Partner than are presently set forth in such Organizational Documents. Any right of an Indemnified Person pursuant to this Section 6.6(a) shall not be amended, repealed, terminated or otherwise modified at any time in a manner that would adversely affect the rights of such Indemnified Person as provided herein, and shall be enforceable by such Indemnified Person and their respective heirs and Representatives against Parent, Surviving Entity and the General Partner and their respective successors and assigns.

(b)The Surviving Entity, or Parent on behalf of the Surviving Entity if Parent, in its sole discretion so elects, shall maintain in effect for a period of six years following the Effective Time the Partnership’s current directors’ and officers’ liability insurance policies covering acts or omissions occurring at or prior to the Effective Time with respect to Indemnified Persons (provided, that the Surviving Entity, or Parent on behalf of the Surviving Entity if Parent so elects, may substitute therefor policies with reputable carriers of at least the same coverage containing terms and conditions that are no less favorable to the Indemnified Persons); provided, however, that in no event shall the Surviving Entity or Parent, as applicable, be required to expend pursuant to this Section 6.6(b) more than an amount per year equal to 300% of current annual premiums paid by the Partnership for such insurance (the “Maximum Amount”). In the event that, but for the proviso to the immediately preceding sentence, the Surviving Entity would be required to expend more than the Maximum Amount, the Surviving Entity, or Parent on behalf of the Surviving Entity if Parent had so elected to provide such insurance, shall obtain the maximum amount of such insurance as is available for the Maximum Amount. In lieu of the obligations of the Surviving Entity and Parent under this Section 6.6(b), the Partnership or Holdings may (but shall be under no obligation to), prior to the Effective Time, purchase a prepaid “tail policy” with respect to acts or omissions occurring or alleged to have occurred prior to the Effective Time that were committed or alleged to have been committed by such Indemnified Persons in their capacity as such; provided, that in no event shall the cost of such policy exceed six times the Maximum Amount.

(c)The rights of any Indemnified Person under this Section 6.6 shall be in addition to any other rights such Indemnified Person may have under the Organizational Documents of each of the Partnership, the General Partner, the Surviving Entity or any Subsidiary of Parent or the Partnership, any indemnification agreements, or the DLLCA or the DRULPA. The provisions of this Section 6.6 shall survive the consummation of the transactions contemplated by this Agreement and are expressly intended to benefit each of the Indemnified Persons and their respective heirs and Representatives. If Parent, the Surviving Entity and/or the General Partner, or any of their respective successors or assigns (i) consolidates with or merges into any other Person, or (ii) transfers or conveys all or substantially all of their businesses or assets to any other Person, then, in each such case, to the extent necessary, a proper provision shall be made so that the successors and assigns of Parent, the Surviving Entity and/or the General Partner shall assume the obligations of Parent, the Surviving Entity and the General Partner set forth in this Section 6.6.

Section 6.7Fees and Expenses. Except as otherwise provided in Section 6.8, Section 8.2 and Section 8.3, all fees and expenses incurred in connection with the transactions contemplated by this Agreement including all legal, accounting, financial advisory, consulting and all other fees and expenses of third parties incurred by a party in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated by this Agreement, shall be the obligation of the respective party incurring such fees and expenses, except (a) Parent and the Partnership shall each bear and pay one half of the expenses incurred in connection with the filing, printing and mailing of the Registration Statement and the Consent Statement/Prospectus and (b) Parent shall pay all costs and fees of the Exchange Agent and all expenses associated with the exchange process.

Section 6.10Stock Exchange Listing, Delisting and Deregistration.

Prior to the Closing, Parent shall submit (a) duly completed applications and/or forms for submission to the LSE and the FCA with respect to such Parent Ordinary Shares in accordance with the requirements of the LSE and the FCA (the “London Applications”) and (b) a supplemental listing application with the NYSE with respect to such Parent ADSs in accordance with the requirements of the NYSE (the “NYSE Listing Application” together with the London Applications, the “Listing Applications”). Parent shall use its reasonable best efforts to have the Listing Applications approved (subject, in the case of the NYSE Listing Application, to official notice of issuance) as promptly as practicable after such submission (including by responding to comments of the NYSE, the LSE and/or the FCA). The Partnership shall furnish all information as may be reasonably requested by Parent in connection with any such action and the preparation and submission of the Listing Applications. No submission of, or amendment or supplement to, the Listing Applications will be made by Parent without providing the Partnership with a reasonable opportunity to review and comment thereon. In addition, Parent agrees to provide the Partnership and its legal counsel with copies of any written comments, and shall inform the Partnership of any oral comments, that Parent or its counsel may receive from time to time from the NYSE, the LSE, the FCA or their respective staffs with respect to the Listing Applications promptly after receipt of such comments, and any written or oral responses thereto. The Partnership and its legal counsel shall be given a reasonable opportunity to review any such written responses and Parent shall give due consideration to the additions, deletions or changes suggested thereto by the Partnership and its counsel.

(b)The Partnership will cooperate and use its reasonable best efforts to cause the delisting of Common Units from the NYSE and the deregistration of such securities under the Exchange Act as promptly as practicable following the Closing in compliance with applicable Law.

Section 6.11Dividends and Distributions. After the date of this Agreement and until the Effective Time, each of the Partnership and Parent shall coordinate with the other regarding the timing of any distributions in respect of Common Units and the record dates and payment dates relating thereto, it being the intention of the parties that holders of Common Units shall not receive, for any quarter, distributions both in respect of Common Units and also dividends in respect of Parent Ordinary Shares represented by the Parent ADSs that they receive in exchange therefor in the Merger, but that they shall receive for any such quarter either: (i) only distributions in respect of Common Units or (ii) only dividends in respect of Parent Ordinary Shares represented by the Parent ADSs that they receive in exchange therefor in the Merger.

Section 6.12Conflicts Committee. Prior to the earlier of the Effective Time and the termination of this Agreement, Parent shall not and it shall not permit any of its Subsidiaries to, and it shall not and shall not permit any of its Subsidiaries to take any action intended to cause the General Partner (or the sole member of the General Partner) to, without the consent of a majority of the then existing members of the Conflicts Committee, eliminate the Conflicts Committee, revoke or diminish the authority of the Conflicts Committee or remove or cause the removal of any director of the General Partner who is a member of the Conflicts Committee either as a director or as a member of such committee. For the avoidance of doubt, this Section 6.12 shall not apply to the filling, in accordance with the provisions of the General Partner Company Agreement, of any vacancies caused by the resignation, death or incapacity of any such director.

Section 6.13Performance by the General Partner. Subject to Section 9.3 and Section 9.4, Holdings will cause the General Partner, the Partnership and their respective Subsidiaries to comply with the provisions of this Agreement and the Support Agreement. Notwithstanding the foregoing, it is understood and agreed that actions or inactions by the Partnership and the General Partner and their respective Subsidiaries shall not be deemed to be breaches or violations or failures to perform by Parent of any of the provisions of this Agreement unless such action or inaction was or was not taken, in either case, at the direction of Holdings. In no event shall the General Partner or the Partnership have any liability for, or be deemed to breach, violate or fail to perform any of the provisions of this Agreement by reason of, any action taken or omitted to be taken by the General Partner, the Partnership, any of their respective Subsidiaries or any of their respective Representatives at the direction of Parent or Holdings.

Section 6.14Tax Matters. For U.S. federal income tax purposes (and for purposes of any applicable state, local or foreign Tax that follows the U.S. federal income tax treatment), the parties agree to treat the Merger as a taxable sale of the Public Common Units to Pipelines, as the tax-regarded owner of Holdings, in exchange for the Merger Consideration. The parties will prepare and file all Tax Returns consistent with the foregoing and will not take any inconsistent position on any Tax Return, or during the course of any Proceeding with respect to Taxes, except as otherwise required by applicable Law following a final determination by a court of competent jurisdiction or other administrative settlement with or final administrative decision by the relevant Governmental Authority.

Section 6.15Takeover Statutes. Parent shall not, and shall cause its Subsidiaries not to, take any action that would, or would reasonably be expected to, cause any Takeover Law to become applicable to this Agreement, the Merger, the Parent Stock Issuance or the other transactions contemplated hereby or related thereto. If any Takeover Law shall become applicable to this Agreement, the Merger or the other transactions contemplated hereby or related thereto, Parent, the Parent Board, the General Partner, the GP Board and the Conflicts Committee shall use reasonable best efforts to take such actions so that the transactions contemplated hereby, including the Merger and the Parent Stock Issuance, may be consummated as promptly as practicable on the terms contemplated hereby and otherwise use reasonable best

efforts to eliminate or minimize the effects of such statute or regulation on the transactions contemplated hereby, including the Merger and the Parent Stock Issuance.

The Partnership and the General Partner shall give Parent prompt notice and the opportunity to participate in the defense or settlement of any securityholder litigation against the Partnership and the General Partner and/or their directors (as applicable) relating to the transactions contemplated by this Agreement and no such settlement shall be agreed to without the prior written consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed.

(b)by either of the Parent or the Partnership:

(i)if the Closing shall not have been consummated on or before September 19, 2022, whether such date is before or after the Written Consent referred to in Section 7.1(a) shall have been obtained (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 8.1(b)(i) shall not be available (A) to Parent or the Partnership if the inability to satisfy such condition was due to the failure of, in the case of Parent, Parent, Holdings or Merger Sub, or, in the case of the Partnership, the Partnership or the General Partner, to perform and comply in all material respects with the covenants and agreements to be performed or complied with by it prior to the Closing or (B) to Parent or the Partnership if, in the case of Parent, the Partnership or the General Partner, or, in the case of the Partnership, Parent, Holdings or Merger Sub, has filed (and is then pursuing) an action seeking specific performance as permitted by Section 9.9; or

(ii)if any Restraint having the effect set forth in Section 7.1(b) shall be in effect and shall have become final and nonappealable (whether before or after the Written Consent referred to in Section 7.1(a) shall have been obtained); provided, however, that the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be available to Parent or the Partnership if such Restraint was due to the failure of, in the case of Parent, Parent, Holdings or Merger Sub, or, in the case of the Partnership, the Partnership or the General Partner, to perform any of its obligations under this Agreement in any material respect;

(c)by Parent if the Partnership or the General Partner shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of the Partnership or the General Partner set forth in this Agreement shall fail to be true), which breach or failure (i) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 7.2(a)(i) or Section 7.2(b) and (ii) is incapable of being cured, or is not cured, by the Partnership or the General Partner within 30 days following receipt of written notice from Parent of such breach or failure; provided, however, that Parent shall not have the right to terminate this Agreement pursuant to this Section 8.1(c) if Parent, Holdings or Merger Sub is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement; or

(d)by the Partnership (which termination may be effected for the Partnership by the Conflicts Committee without the consent, authorization or approval of the GP Board) if Parent shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of Parent set forth in this Agreement shall fail to be true), which breach or failure (i) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 7.3(a)(i) or Section 7.3(b) and (ii) is incapable of being cured, or is not cured, by Parent within 30 days following receipt of written notice from the Partnership of such breach or failure;

provided, that the Partnership shall not have the right to terminate this Agreement pursuant to this Section 8.1(d) if the Partnership or the General Partner is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement.

Section 8.2Effect of Termination. In the event of the termination of this Agreement as provided in Section 8.1, written notice thereof shall be given to the other party or parties, specifying the provision of this Agreement pursuant to which such termination is made, and this Agreement shall forthwith become null and void (other than the provisions in the last sentence of Section 6.5, the provisions in Section 6.7, this Section 8.2, Section 8.3 and Article IX, all of which shall survive termination of this Agreement), and, except as otherwise provided in this Section 8.2, there shall be no liability on the part of any of Parent, Holdings, Merger Sub, the Partnership and the General Partner or their respective Representatives, directors, officers and Affiliates; provided, however, that no such termination shall relieve any party hereto from: (a) its obligation to pay the Parent Expense Reimbursement or the Partnership Expense Reimbursement, as applicable, if, as and when required pursuant to Section 8.3, or (b) any liability for intentional fraud or a Willful Breach of any covenant or other agreement contained in this Agreement. Notwithstanding the foregoing, in no event shall the General Partner or the Partnership have any liability for any matter set forth in the proviso of the preceding sentence for any action taken or omitted to be taken by the General Partner, the Partnership, any of their respective Subsidiaries or any of their respective Representatives at the direction of Parent or Holdings. For purposes of this Agreement, “Willful Breach” shall mean a material breach of this Agreement that is a consequence of a deliberate act or a deliberate failure to act by the breaching party with the knowledge that the taking of such act (or the failure to take such act) would (i) cause a material breach of this Agreement and (ii) prevent or materially delay the Closing.

Section 8.3Expenses.

(a)In the event of termination of this Agreement by Parent pursuant to Section 8.1(c) (Partnership or General Partner Uncured Breach), then the Partnership shall promptly, but in no event later than five Business Days after receipt of an invoice (with supporting documentation) therefor from Parent, pay Parent’s designee all of the reasonably documented out-of-pocket expenses (including all fees and expenses of counsel, accountants, investment bankers, financing sources, hedging counterparties, experts and consultants) incurred by Parent and its Affiliates in connection with this Agreement and the transactions contemplated hereby up to a maximum amount of $5,000,000 (the “Parent Expense Reimbursement”).

(b)In the event of termination of this Agreement by the Partnership pursuant to Section 8.1(d) (Parent Uncured Breach), then Parent shall promptly, but in no event later than five Business Days after receipt of an invoice (with supporting documentation) therefor from the Partnership, pay the Partnership’s designee all of the reasonably documented out-of-pocket expenses (including all fees and expenses of counsel, accountants, investment bankers, financing sources, hedging counterparties, experts and consultants) incurred by the Partnership and its Affiliates in connection with this Agreement and the transactions contemplated hereby up to a maximum amount of $5,000,000 (the “Partnership Expense Reimbursement”); provided, that the Partnership Expense Reimbursement shall not exceed the maximum amount, if any, that the Partnership reasonably determines can be paid to the Partnership without causing the Partnership to fail the gross income requirement in Section 7704(c)(2) of the Code, treating the Partnership Expense Reimbursement as non-qualifying income and after taking into consideration all other sources of non-qualifying income of the Partnership, unless the Partnership receives an opinion of counsel or a ruling from the Internal Revenue Service to the effect that the Partnership’s receipt of the Partnership Expense Reimbursement will either constitute qualifying income (as defined in Section 7704(d) of the Code) or be excluded from gross income for purposes of Section 7704 of the Code.

(c)Each of the parties hereto acknowledges that the Parent Expense Reimbursement and Partnership Expense Reimbursement are not intended to be a penalty, but rather are liquidated damages in a reasonable amount that will compensate the other party, as applicable, in the circumstances in which such amounts are due and payable and which do not involve intentional fraud or Willful Breach, for the efforts and resources expended and opportunities forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. In no event shall a party be entitled to more than one payment of the Parent Expense Reimbursement and Partnership Expense Reimbursement, as applicable, in connection with a termination of this Agreement pursuant to which such amounts are payable.

The representations, warranties and agreements in this Agreement (including, for the avoidance of doubt, any schedule, instrument or other document delivered pursuant to this Agreement) shall terminate at the Effective Time or, except as otherwise provided in Section 8.2 or Section 8.3, upon the termination of this Agreement pursuant to Section 8.1, as the case may be, except that the agreements set forth in Article I, Article II, Article III, Section 6.6, Section 6.7 and Article IX and any other agreement in this Agreement that contemplates performance after the Effective Time shall survive the Effective Time.

Section 9.2Amendment or Supplement. At any time prior to the Effective Time, this Agreement may be amended or supplemented in any and all respects by written agreement of the parties, by action taken or authorized by the Parent Board acting through its authorized delegates and the Conflicts Committee; provided, that there shall be no amendment or change to the provisions of this Agreement that by applicable Laws, the Partnership Agreement or stock exchange rule would require further approval by Limited Partners without obtaining the requisite approval of the Limited Partners.

Section 9.3GP Board Consent. Unless otherwise expressly set forth in this Agreement, whenever a determination, decision, approval, consent, waiver or agreement of the Partnership or the General Partner is required pursuant to this Agreement (including any determination to exercise or refrain from exercising any rights under Article VIII or to enforce the terms of this Agreement (including Section 9.9)), such determination, decision, approval, consent, waiver or agreement must be authorized in writing by the Conflicts Committee on behalf of the General Partner.

Section 9.4Extension of Time, Waiver, Etc. At any time prior to the Effective Time, any party may, subject to applicable Law, (a) waive any inaccuracies in the representations and warranties of any other party hereto, (b) extend the time for the performance of any of the obligations or acts of any other party hereto, (c) waive compliance by the other party with any of the agreements contained herein or, except as otherwise provided herein, waive any of such party’s conditions or (d) make or grant any consent under this Agreement; provided, however, that the General Partner may not take or authorize any such action unless it has been approved in writing by the Conflicts Committee. Notwithstanding the foregoing, no failure or delay by the Partnership, Holdings, the General Partner, Parent or Merger Sub in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.

Section 9.5Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of Law or otherwise, by any of the parties without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns. Any purported assignment not permitted under this Section 9.5 shall be null, void and ineffective.

Section 9.6Counterparts. This Agreement may be executed in counterparts (each of which shall be deemed to be an original but all of which taken together shall constitute one and the same agreement) and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” form, or

by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature. For the avoidance of doubt a party's execution and delivery of this Agreement by electronic signature and electronic transmission, including via DocuSign or other similar method, shall constitute the execution and delivery of a counterpart of this Agreement by or on behalf of such party and shall bind such party to the terms of this Agreement.

Section 9.7Entire Understanding; No Third-Party Beneficiaries. This Agreement, the Partnership Disclosure Schedule, the Parent Disclosure Schedule, the Support Agreement and any certificates delivered by any party pursuant to this agreement (a) constitute the entire agreement and understanding, and supersede all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter of this Agreement and thereof and (b) shall not confer upon any Person other than the parties hereto any rights (including third-party beneficiary rights or otherwise) or remedies hereunder, except for, in the case of clause (b) of this sentence, (i) the right of a holder of Public Common Units to receive the Merger Consideration (a claim by any holder of Public Common Units with respect to which may not be made unless and until the Closing shall have occurred), (ii) the right of a holder of a Partnership LTIP Award to receive the Merger Consideration (a claim by any holder of Partnership LTIP Award with respect to which may not be made unless and until the Closing shall have occurred) and (iii) the provisions of Section 6.6 and Section 9.12.

Section 9.8Governing Law; Jurisdiction; Waiver of Jury Trial.

(a)This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, applicable to contracts executed in and to be performed entirely within that State.

(b)Each of the parties hereto irrevocably agrees that any legal action or Proceeding with respect to this Agreement and the rights and obligations arising hereunder, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the parties hereto consents to service being made through the notice procedures set forth in Section 9.10, irrevocably submits with regard to any such action or Proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or Proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 9.8, (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Laws, any claim that (A) the suit, action or Proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or Proceeding is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each party hereto expressly acknowledges that the foregoing waiver is intended to be irrevocable under the Law of the State of Delaware and of the United States of America; provided, however, that each such party’s consent to jurisdiction and service contained in this Section 9.8(b) is solely for the purpose referred to in this Section 9.8(b) and shall not be deemed to be a general submission to such courts or in the State of Delaware other than for such purpose.

(c)EACH PARTY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

Section 9.9Specific Performance. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and it is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 9.9 in the Delaware Court of Chancery or any other state or federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (a) either party has an adequate remedy at law or (b) an award of specific performance is not an appropriate remedy for any reason at law or equity (it being understood that nothing in this sentence shall prohibit the parties hereto from raising other defenses to a claim for specific performance or other equitable relief under this Agreement). Each party further agrees that no party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 9.9, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

All notices and other communications hereunder must be in writing and will be deemed duly given if delivered personally or by email transmission, or mailed through a nationally recognized overnight courier, postage prepaid, to the parties at the following addresses (or at such other address for a party as specified by like notice, provided, however, that notices of a change of address will be effective only upon receipt thereof):

Section 9.11Severability.

Section 9.12Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, equityholder, agent, attorney, financing source, Representative or Affiliate of any party hereto or of any of their respective Affiliates (unless such Affiliate is expressly a party to this Agreement) shall have any liability (whether in contract or in tort or otherwise) for any obligations or liabilities 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 by this Agreement; provided, however, that nothing in this Section 9.12 shall limit any liability of the parties to this Agreement for breaches of the terms and conditions of this Agreement.
