Section 1.5 Organizational Documents of the Surviving Entity.

(b) At the Effective Time, by virtue of the Merger and without any action on the part of SXE GP, AMID GP or their respective members, (i) the SXE Partnership Agreement shall remain unchanged and shall continue in effect until thereafter changed or amended as provided therein or by applicable Law and (ii) all limited partners of SXE immediately prior to the Effective Time shall simultaneously cease to be limited partners of SXE.

ARTICLE II

EFFECT ON UNITS

Section 2.1 Effect of Merger. At the Effective Time, by virtue of the Merger and without any action on the part of SXE GP, SXE, AMID GP, AMID or the holder of any securities of SXE:

(a) Conversion of Common Units. Subject to Section 2.1(c), Section 2.2(h) and Section 2.4, (i) each Common Unit issued and outstanding as of immediately prior to the Effective Time (other than Common Units held by Southcross Holdings or any of its Subsidiaries) shall be converted into the right to receive 0.160 (the “Exchange Ratio”) AMID Units (the “Merger Consideration”), and (ii) each Common Unit, Subordinated Unit and Class B Convertible Unit issued and outstanding held by Southcross Holdings or any of its Subsidiaries, as of the Effective Time, shall cease to be outstanding and shall be cancelled and retired and shall cease to exist and no consideration will be delivered in exchange for such cancelled SXE Securities.

(b) Cancellation of SXE Incentive Distribution Rights. The SXE Incentive Distribution Rights outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and no consideration will be delivered in exchange for such cancelled SXE Incentive Distribution Rights.

(c) Cancellation of SXE-Owned Units. Any SXE Securities that are owned upon consummation of the Holdings Contribution and immediately prior to the Effective Time by AMID, SXE or any of their respective Subsidiaries shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange for such canceled SXE Securities.

(d) Conversion of the Membership Interests in Merger Sub. The membership interests in Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into Common Units of SXE (as the Surviving Entity), representing 100% of the aggregate partnership interest (as defined in the DRULPA) of all limited partners in the Surviving Entity, and AMID shall be admitted as the only limited partner of the Surviving Entity. At the Effective Time, the books and records of SXE (as the Surviving Entity) shall be revised to reflect the admission of AMID as the only limited partner of the Surviving Entity and the simultaneous withdrawal of all other SXE Limited Partners.

(e) Certificates. All Common Units converted into the Merger Consideration pursuant to this Article II shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate (or effective affidavits of loss in lieu thereof) (a “Certificate”) or evidence of units in book-entry form (“Book-Entry Units”) that immediately prior to the Effective Time represented any such Common Units shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, any distributions to which such holder is entitled pursuant to Section 2.2(g) to be issued or paid in consideration therefor upon surrender of such Certificate or Book-Entry Unit in accordance with Section 2.2(c), without interest, and the right to be admitted as an AMID Limited Partner. AMID GP hereby consents to the admission (as an AMID Limited Partner) of each SXE Unitholder who is issued AMID Units in accordance with this Article II, upon the proper surrender of the Certificate or Book-Entry Unit representing Common Units. Upon such surrender of the Certificate or Book-Entry Unit and the recording of the name of such Person as a limited partner of AMID on the books and records of AMID, such Person shall automatically and effective as of the Effective Time be admitted as an AMID Limited Partner and be bound by the AMID Partnership Agreement as such. By its surrender of a Certificate or Book-Entry Unit, or by its acceptance of AMID Units, as applicable, a SXE Unitholder confirms its agreement to be bound by all of the terms and conditions of the AMID Partnership Agreement.

Section 2.2 Exchange of Certificates.

(a) Exchange Agent. Prior to the Closing Date, AMID shall appoint an exchange agent reasonably acceptable to SXE (the “Exchange Agent”) for the purpose of exchanging Certificates or Book-Entry Units for the Merger Consideration. As soon as reasonably practicable after the Effective Time, but in no event more than five business days following the Effective Time, AMID will send, or will cause the Exchange Agent to send, to each holder of record of Common Units as of the Effective Time (and, to the extent commercially practicable, to make available for collection by hand, during customary business hours commencing immediately after the Effective Time, if so elected by such holder of record), whose Common Units were converted into the right to receive the Merger Consideration, a letter of transmittal (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates to the Exchange Agent) in such forms as SXE and AMID may reasonably agree, including, as applicable, instructions for use in effecting the surrender of Certificates or Book-Entry Units to the Exchange Agent in exchange for the Merger Consideration.

(b) Deposit. At or prior to the Closing, AMID shall cause to be deposited with the Exchange Agent, in trust for the benefit of the holders of Common Units whose Common Units were converted into the right to receive the Merger Consideration an amount of AMID Units (which shall be in non-certificated book-entry form) issuable upon due surrender of the Certificates or Book-Entry Units pursuant to the provisions of this Article II. Following the Effective Time, AMID agrees to make available to the Exchange Agent, from time to time as needed, cash in U.S. dollars sufficient to pay any distributions pursuant to Section 2.2(g), any AMID Units sufficient to pay any Merger Consideration and any that may be payable from time

to time following the Effective Time. All cash or book-entry units representing AMID Units deposited with the Exchange Agent or representing AMID Units to be delivered pursuant to Section 2.2(h) shall be referred to in this Agreement as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be issued or paid pursuant to this Article II out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose.

(c) Exchange. Each holder of Common Units that have been converted into the right to receive the Merger Consideration upon surrender to the Exchange Agent of a Book-Entry Unit or a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto and a Certificate and such other documents as may reasonably be required by the Exchange Agent, will be entitled to receive in exchange therefor (x) the number of AMID Units representing, in the aggregate, the whole number of AMID Units that such holder has the right to receive in accordance with the provisions of this Article II and/or (y) a check denominated in U.S. dollars in the amount of cash, if any, that such holder has the right to receive pursuant to this Article II. The Merger Consideration shall be paid as promptly as practicable by mail after receipt by the Exchange Agent of the Book-Entry Unit or Certificate and letter of transmittal in accordance with the foregoing. No interest shall be paid or accrued on any Merger Consideration or on any unpaid distributions payable to holders of Certificates or Book-Entry Units. Until so surrendered, each such Certificate or Book-Entry Unit shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration. The Merger Consideration paid upon surrender of Certificates or Book-Entry Units shall be deemed to have been paid in full satisfaction of all rights pertaining to the Common Units, as the case may be, formerly represented by such Certificates or Book-Entry Units.

(d) Other Payees. If any portion of the Merger Consideration is to be registered in the name of a Person other than the Person in whose name the applicable surrendered Certificate or Book-Entry Unit is registered, it shall be a condition to the registration thereof that the surrendered Certificate or Book-Entry Unit shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other similar Taxes required as a result of such registration in the name of a Person other than the registered holder of such Certificate or Book-Entry Unit or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) No Further Transfers. From and after the Effective Time, there shall be no further registration on the books of SXE of transfers of Common Units. From and after the Effective Time, the holders of Certificates or Book-Entry Units representing Common Units outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Common Units, except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates or Book-Entry Units are presented to the Exchange Agent or AMID, they shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article II.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the Common Unitholders 12 months after the Effective Time shall be returned to AMID, upon demand, and any such holder who has not exchanged such holder’s

Common Units for the Merger Consideration in accordance with this Section 2.2 prior to that time shall thereafter look only to AMID for delivery of the Merger Consideration as applicable, in respect of such holder’s Common Units. Notwithstanding the foregoing, AMID and SXE shall not be liable to any Common Unitholder for any Merger Consideration duly delivered to a public official pursuant to applicable abandoned property Laws. Any Merger Consideration remaining unclaimed by Common Unitholders immediately prior to such time as such amounts would otherwise escheat to, or become property of, any Governmental Authority shall, to the extent permitted by applicable Law, become the property of AMID free and clear of any claims or interest of any Person previously entitled thereto.

(g) Distributions. No distributions with respect to AMID Units 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 2.2. Following such surrender, subject to the effect of escheat, Tax or other applicable Law, there shall be paid, without interest, to the record holder of the AMID Units, if any, issued in exchange therefor (i) at the time of such surrender, all distributions payable in respect of any such AMID Units 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 distributions payable with respect to such AMID Units with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of distributions in respect of AMID Units, all AMID Units to be issued pursuant to the Merger shall be entitled to distributions pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

(h) No Fractional Units. No certificates or scrip representing fractional AMID Units shall be issued upon the surrender for exchange of Certificates or Book-Entry Units. Notwithstanding any other provision of this Agreement, all fractional AMID Units that a holder of Common Units converted pursuant to the Merger would otherwise be entitled to receive as Merger Consideration (after taking into account all Certificates or Book-Entry Units delivered by such holder) will be aggregated and then, if a fractional AMID Unit results from that aggregation, be rounded up to the nearest whole AMID Unit.

(i) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by AMID, the posting by such Person of a bond, in such reasonable amount as AMID may direct, 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 the Merger Consideration to be paid in respect of the Common Units represented by such Certificate as contemplated by this Article II.

(j) Withholding Taxes. AMID and the Exchange Agent shall deduct and withhold from the consideration otherwise payable pursuant to this Agreement to a Common Unitholder such amounts as are required to be deducted and withheld with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations promulgated thereunder, or under any provision of applicable state, local or foreign Tax Law (and to the extent deduction and withholding is required, such deduction and withholding shall be taken in AMID Units). To the extent amounts are so withheld and paid over to the appropriate Tax authority, such withheld amounts shall be treated for the purposes of this

Agreement as having been paid to the former holder of the Common Units, as applicable, in respect of whom such withholding was made. If withholding is taken in AMID Units, AMID and the Exchange Agent shall be treated as having sold such consideration for an amount of cash equal to the fair market value of such consideration at the time of such deemed sale and paid such cash proceeds to the appropriate Tax authority.

(k) Tax Characterization of the Merger. The Parties hereby acknowledge that, for U.S. federal income Tax purposes, the Merger will be treated as an “assets-over” partnership merger transaction under Treasury Regulations Sections 1.708-1(c)(1) and 1.708-1(c)(3)(i), whereby, SXE will be the terminating partnership and AMID will be the resulting partnership and, as a result, the Merger will qualify in part for nonrecognition of gain or loss pursuant to Section 721 of the Code and will be characterized as a disguised sale transaction described in Section 707(a)(2)(B) of the Code with respect to the cash consideration, if any, and any liabilities assumed in the transaction (other than “qualified liabilities” within the meaning of Treasury Regulations Section 1.707-5(a)(6) to the extent provided in the Treasury Regulations) (the “Section 707 Consideration”). Each Party agrees to prepare and file all U.S. federal income Tax Returns in accordance with the foregoing and shall not take any position inconsistent therewith on any such Tax Return, or in the course of any audit, litigation or other proceeding with respect to U.S. federal income Taxes, except as otherwise required by applicable Laws following a final determination by a court of competent jurisdiction or other final administrative decision by an applicable Governmental Authority.

Section 2.3 Treatment of the SXE LTIP Units. Immediately prior to the Effective Time, each award of SXE LTIP Units that is then outstanding shall be fully vested and settled in the form of Common Units, provided that SXE shall withhold a portion of the Common Units that would otherwise be delivered upon vesting an amount equal to any applicable federal, state and local taxes, and the holder of such Common Units shall receive the consideration provided under Section 2.1(a) above. Any tandem dividend equivalent right issued in connection with an award of SXE LTIP Units shall be settled as soon as administratively feasible following the Effective Time. As of the Effective Time, AMID shall assume such plans for purposes of employing such plans to make grants of equity based awards on AMID Units following the Closing.

Section 2.4 Adjustments. Notwithstanding any provision of this Article II to the contrary (but without in any way limiting the covenants in Section 5.2), if between the date of this Agreement and the Effective Time the number of outstanding Common Units or AMID Units shall have been changed into a different number of units or a different class by reason of the occurrence or record date of any unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, unit combination, exchange of units or similar transaction, the Exchange Ratio shall be appropriately adjusted to reflect fully the effect of such unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, unit combination, exchange of units or similar transaction and to provide the holders of Common Units the same economic effect as contemplated by this Agreement prior to such event.

Section 2.5 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated hereby.

Section 3.5 SXE SEC Documents; Undisclosed Liabilities.

(a) SXE and its Subsidiaries have filed and furnished all reports, schedules, forms, certifications, prospectuses, and registration, proxy and other statements required to be filed by them with the SEC since December 31, 2014 (collectively and together with all documents filed on a voluntary basis on Form 8-K, and in each case including all exhibits and schedules thereto and documents incorporated by reference therein, the “SXE SEC Documents”). The SXE SEC Documents, as of their respective effective dates (in the case of the SXE SEC Documents that are registration statements filed pursuant to the requirements of the Securities Act) and as of their respective SEC filing dates (in the case of all other SXE SEC Documents), or, if amended, as finally amended prior to the date of this Agreement, complied in all material respects with the requirements of the Exchange Act, the Securities Act and the Xxxxxxxx-Xxxxx Act of 2002, as amended, and the rules and regulations promulgated thereunder (the “Xxxxxxxx-Xxxxx Act”), as the case may be, applicable to such SXE SEC Documents, and none of the SXE SEC Documents as of such respective dates contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

To the Knowledge of SXE, as of the date of this Agreement there are no facts or circumstances that would prevent its principal executive officer and principal financial officer from giving the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Xxxxxxxx-Xxxxx Act, without qualification, when next due.

Section 4.5 AMID SEC Documents; Undisclosed Liabilities.

(a) AMID and its Subsidiaries have filed and furnished all reports, schedules, forms, certifications, prospectuses, and registration, proxy and other statements required to be filed by them with the SEC since December 31, 2014 (collectively and together with all documents filed on a voluntary basis on Form 8-K, and in each case including all exhibits and schedules thereto and documents incorporated by reference therein, the “AMID SEC Documents”). The AMID SEC Documents, as of their respective effective dates (in the case of the AMID SEC Documents that are registration statements filed pursuant to the requirements of the Securities Act) and as of their respective SEC filing dates (in the case of all other AMID SEC Documents), or, if amended, as finally amended prior to the date of this Agreement, complied in all material respects with the requirements of the Exchange Act, the Securities Act and the Xxxxxxxx-Xxxxx Act, as the case may be, applicable to such AMID SEC Documents, and none of the AMID SEC Documents as of such respective dates contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order

to make the statements therein, in light of the circumstances under which they were made, not misleading. As of the date of this Agreement, there are no outstanding or unresolved comments received from the SEC staff with respect to the AMID SEC Documents. To the Knowledge of AMID, none of the AMID SEC Documents is the subject of ongoing SEC review or investigation.

(b) The consolidated financial statements of AMID included in the AMID SEC Documents as of their respective dates (if amended, as of the date of the last such amendment) comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with GAAP (except, in the case of unaudited quarterly statements, as indicated in the notes thereto) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly present in all material respects the consolidated financial position of AMID and its consolidated Subsidiaries as of the dates thereof and the consolidated results of their operations, cash flows and changes in partners’ equity for the periods then ended (subject, in the case of unaudited quarterly statements, to normal year-end audit adjustments, none of which has been or will be, individually or in the aggregate, material to AMID and its consolidated Subsidiaries, taken as a whole).

(c) AMID has established and maintains internal control over financial reporting and disclosure controls and procedures (as such terms are defined in Rule 13a-15 and Rule 15d-15 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to AMID, including its consolidated Subsidiaries, required to be disclosed by AMID in the reports that it files or submits under the Exchange Act is accumulated and communicated to AMID’s principal executive officer and its principal financial officer to allow timely decisions regarding required disclosure; and such disclosure controls and procedures are effective to ensure that information required to be disclosed by AMID in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. AMID’s principal executive officer and its principal financial officer have disclosed, based on their most recent evaluation, to AMID’s auditors and the audit and risk committee of the AMID GP Board (x) all significant deficiencies in the design or operation of internal controls which could adversely affect AMID’s ability to record, process, summarize and report financial data and have identified for AMID’s auditors any material weaknesses in internal controls and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in AMID’s internal controls. The principal executive officer and the principal financial officer of AMID have made all certifications required by the Xxxxxxxx-Xxxxx Act, the Exchange Act and any related rules and regulations promulgated by the SEC with respect to the AMID SEC Documents, and the statements contained in such certifications were complete and correct when made.

Section 5.3 No Solicitation.

(a) SXE and SXE GP shall, and SXE shall cause its Subsidiaries and use reasonable best efforts to cause SXE’s and its Subsidiaries’ respective directors, officers, employees, investment bankers, financial advisors, attorneys, accountants, agents and other representatives (collectively, “Representatives”) to, immediately cease and cause to be terminated any discussions or negotiations with any Person conducted heretofore with respect to a SXE Alternative Proposal, request the return or destruction of all confidential information previously provided to such parties by or on behalf of SXE or its Subsidiaries and immediately prohibit any access by any Person (other than AMID and its Representatives) to any physical or electronic data room relating to a possible SXE Alternative Proposal. Except as permitted by this Section 5.3, (x) SXE and SXE GP shall not, and SXE shall cause its Subsidiaries and use reasonable best efforts to cause its Representatives not to, directly or indirectly (i) solicit, initiate, knowingly facilitate, knowingly encourage (including by way of furnishing confidential information) or knowingly induce or take any other action intended to lead to any inquiries or any proposals that constitute the submission of a SXE Alternative Proposal, (ii) grant approval to any Person under clause (iii) of the provision in the definition of “Outstanding” in the SXE Partnership Agreement, (iii) enter into any confidentiality agreement, merger agreement, letter of intent, agreement in principle, unit purchase agreement, asset purchase agreement or unit exchange agreement, option agreement or other similar agreement relating to a SXE Alternative

Proposal or (iv) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to AMID, the SXE Board Recommendation or publicly recommend the approval or adoption of, or publicly approve or adopt, or propose to publicly recommend, approve or adopt, any SXE Alternative Proposal and (y) within ten business days of receipt of a written request of AMID following the receipt by SXE of any SXE Alternative Proposal, SXE shall publicly reconfirm the SXE Board Recommendation; provided that AMID shall not be permitted to make such request on more than one occasion in respect of each SXE Alternative Proposal and each material modification to a SXE Alternative Proposal, if any (the taking of any action described in clause (x)(iv) or the failure to take the action described in clause (y) being referred to as an “SXE Adverse Recommendation Change”). Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by SXE’s Subsidiaries or Representatives shall be deemed to be a breach of this Section 5.3 by SXE unless such violation is committed without the Knowledge of SXE and SXE uses its reasonable best efforts to promptly cure such violation once SXE is made aware of such violation.

(b) In addition to the other obligations of SXE set forth in this Section 5.3, SXE shall promptly advise AMID, orally and in writing, and in no event later than 48 hours after receipt, if any proposal, offer, inquiry or other contact is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, SXE in respect of any SXE Alternative Proposal, and shall, in any such notice to AMID, indicate the identity of the Person making such proposal, offer, inquiry or other contact and the material terms and conditions of any proposals or offers or the nature of any inquiries or contacts (and shall include with such notice copies of any written materials received from or on behalf of such Person relating to such proposal, offer, inquiry or request), and thereafter shall promptly keep AMID reasonably informed of all material developments affecting the status and terms of any such proposals, offers, inquiries or requests (and SXE shall promptly provide AMID with copies of any additional written materials received by SXE or that SXE has delivered to any third party making a SXE Alternative Proposal that relate to such proposals, offers, inquiries or requests) and of the status of any such discussions or negotiations.

(c) Notwithstanding any other provision of this Agreement, at any time prior to obtaining the SXE Unitholder Approval, the SXE GP Board (upon the recommendation of the SXE Conflicts Committee) may effect a SXE Adverse Recommendation Change in response to a SXE Designated Proposal or a SXE Changed Circumstance if the SXE GP Board, after consultation with SXE GP’s financial advisor and outside legal counsel, determines in good faith that the failure to take such action would not be in the best interest of SXE and would be inconsistent with its duties under the SXE Partnership Agreement and applicable Law and:

(i) if the SXE GP Board intends to effect such SXE Adverse Recommendation Change in response to a SXE Designated Proposal:

(A) such SXE Alternative Proposal is bona fide, in writing and has not been withdrawn or abandoned;

(B) the SXE GP Board has determined, after consultation with SXE GP’s outside legal counsel and financial advisors, that such SXE Alternative Proposal constitutes a SXE Designated Proposal;

(C) SXE has provided prior written notice to AMID in accordance with Section 8.9 (the “SXE Designated Proposal Notice”) of the SXE GP Board’s intention to effect a SXE Adverse Recommendation Change, and such SXE Designated Proposal Notice has specified the identity of the Person making such SXE Alternative Proposal, the material terms and conditions of such SXE Alternative Proposal, and complete copies of any written proposal or offers (including proposed agreements) received by SXE in connection with such SXE Alternative Proposal;

(D) during the period that commences on the date of delivery of the SXE Designated Proposal Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day following the date of such delivery (the “SXE Designated Proposal Notice Period”), SXE shall (1) negotiate with AMID in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the SXE GP Board not to effect a SXE Adverse Recommendation Change; and (2) keep AMID reasonably informed with respect to the status and changes in the material terms and conditions of such SXE Alternative Proposal or other change in circumstances related thereto; provided, however, that any material revisions to such SXE Alternative Proposal (it being agreed that any change in the form, amount or timing of payment of consideration in such SXE Alternative Proposal shall be deemed a material revision) shall require delivery of a subsequent SXE Designated Proposal Notice and a subsequent SXE Designated Proposal Notice Period in respect of such revised SXE Alternative Proposal, except that such subsequent SXE Designated Proposal Notice Period shall expire upon the later of (x) the end of the initial SXE Designated Proposal Notice Period and (y) 11:59 p.m. Central time on the date that is the third calendar day following the date of the delivery of such subsequent SXE Designated Proposal Notice; and

(E) the SXE GP Board shall have considered all revisions to the terms of this Agreement offered in writing by AMID and, at the end of the SXE Designated Proposal Notice Period, shall have determined in good faith, after consultation with SXE GP’s financial advisor and outside legal counsel, that (i) such SXE Alternative Proposal continues to constitute a SXE Designated Proposal even if such revisions were to be given effect and (ii) failure to effect a SXE Adverse Recommendation Change would not be in the best interest of SXE and would be inconsistent with its duties under the SXE Partnership Agreement and applicable Law even if such revisions were to be given effect; or

(ii) if the SXE GP Board intends to effect such SXE Adverse Recommendation Change in response to a SXE Changed Circumstance:

(A) SXE has provided prior written notice to AMID in accordance with Section 8.9 (the “SXE Recommendation Change Notice”) of the SXE GP Board’s intention to effect a SXE Adverse Recommendation Change, and such SXE Recommendation Change Notice has specified the details of such SXE Changed Circumstance and the reasons for the SXE Adverse Recommendation Change;

(B) during the period that commences on the date of delivery of the SXE Recommendation Change Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day following the date of such delivery (the “SXE Recommendation Change Notice Period”), SXE shall (i) negotiate with AMID in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the SXE GP Board not to effect a SXE Adverse Recommendation Change; and (ii) keep AMID reasonably informed of any change in circumstances related thereto; and

(C) the SXE GP Board shall have considered all revisions to the terms of this Agreement offered in writing by AMID and, at the end of the SXE Recommendation Change Notice Period, shall have determined in good faith, after consultation with SXE GP’s financial advisor and outside legal counsel, that the failure to effect a SXE Adverse Recommendation Change would not be in the best interest of SXE and would be inconsistent with its duties under the SXE Partnership Agreement and applicable Law even if such revisions were to be given effect.

(d) Nothing contained in this Agreement shall prevent SXE or the SXE GP Board from issuing a “stop, look and listen” communication pursuant to Rule 14d-9(f) under the Exchange Act or complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to a SXE Alternative Proposal if the SXE GP Board determines in good faith (after consultation with outside legal counsel) that its failure to do so would be reasonably likely to constitute a violation of applicable Law; provided that any SXE Adverse Recommendation Change may only be made in accordance with Section 5.3(d). For the avoidance of doubt, a public statement that describes SXE’s receipt of a SXE Alternative Proposal and the operation of this Agreement with respect thereto shall not be deemed to be a violation of this Section 5.3 or a SXE Adverse Recommendation Change.

Section 5.4 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement (including Section 5.4(d)), each of the AMID Entities, on the one hand, and the SXE Entities, on the other hand, shall cooperate with the other and use (and shall cause their respective Subsidiaries to use) its reasonable best efforts to (i) take, or cause to be taken, all actions, and do, or cause to be done, and to assist and cooperate with the other in doing, all things, necessary, proper or advisable under applicable Law to cause the conditions to the Closing to be satisfied as promptly as practicable (and in any event no later than the Outside Date) and to consummate and make

AMID shall have the principal responsibility for devising and implementing the strategy for obtaining any clearances required under any Antitrust Law in connection with the transactions contemplated hereby and shall take the lead in all meetings and communications with any Governmental Authority in connection with obtaining such clearances, provided, however, that AMID shall consult in advance with SXE and in good faith take SXE’s views into account regarding the overall strategy. Subject to Section 5.6(b), the Parties shall take reasonable efforts to share information protected from disclosure under the attorney-client privilege, work product doctrine, joint defense privilege or any other privilege pursuant to this Section 5.4 in a manner so as to preserve the applicable privilege.

(d) AMID and SXE (including by causing their respective Subsidiaries) agree to use their reasonable best efforts to (x) resolve any objections that a Governmental Authority or other Person may assert under any Antitrust Law with respect to the transactions contemplated hereby, and (y) avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Authority with respect to the transactions contemplated hereby, in each case, so as to enable the Closing to occur as promptly as practicable and in any event no later than the Outside Date. Notwithstanding the foregoing, this clause (d) shall not impose any requirement on AMID or SXE to (i) to dispose, transfer, or separate any assets or operations, (ii) limit AMID’s freedom of action with respect to, or its ability to consolidate and control, SXE or any of their assets or businesses or any of AMID’s or its Affiliates’ other assets or businesses or (iii) limit AMID’s ability to acquire or hold, or exercise full rights of ownership with respect to, SXE.

the other Party); provided, however, that (a) SXE shall not be required by this Section 5.5 to consult with any other Party with respect to a public announcement in connection with a SXE Adverse Recommendation Change but nothing in this clause (a) shall limit any obligation of SXE under Section 5.1 or Section 5.3; provided, further, that each Party and their respective controlled affiliates may make statements that are consistent with statements made in previous press releases, public disclosures or public statements made by AMID or SXE in compliance with this Section 5.5.

Each of the Parties hereto hereby 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 hereby 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 8.7, (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 Law, any claim that (x) the suit, action or proceeding in such court is brought in an inconvenient forum, (y) the venue of such suit, action or proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

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 (x) either Party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity. 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 8.8, and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

(c) The Disclosure Schedules to this Agreement are arranged in sections corresponding to those contained in this Agreement merely for convenience, and the disclosure of an item in one section or subsection of such Disclosure Schedules as an exception to any particular covenant, representation or warranty shall be deemed adequately disclosed as an exception with respect to all other covenants, representations or warranties, notwithstanding the presence or absence of an appropriate section or subsection of such Disclosure Schedules with respect to such other covenants, representations or warranties or an appropriate cross-reference thereto, in each case to the extent relevancy of such disclosure to such other covenants, representations or warranties is reasonably apparent on the face of such disclosure that such disclosed information is applicable thereto. Additionally, for each of the Disclosure Schedules, the mere inclusion of an item in such Disclosure Schedules as an exception to a representation or warranty shall not be deemed an admission or acknowledgment, in and of itself and solely by virtue of the inclusion of such information in such Disclosure Schedules, that such information is required to be listed in such Disclosure Schedules or that such item (or any non-disclosed item or information of comparable or greater significance) represents a material exception or fact, event or circumstance, that such item has had, or is expected to result in, a SXE Material Adverse Effect or a AMID Material Adverse Effect, that such item actually constitutes noncompliance with, or a violation of, any Law, Permit or contract or other topic to which such disclosure is applicable or that such item is outside the ordinary course of business. The specification of any dollar amount in the representations and warranties contained in this Agreement or the inclusion of any specific item in the Disclosure Schedules is not intended to imply that such amounts (or higher or lower amounts) are or are not material, and no Party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item in the Disclosure Schedules in any dispute or controversy between the Parties as to whether any obligation, item, or matter not described herein or included in a Disclosure Schedule is or is not material for purposes of this Agreement.
