2.6 Closing Adjustment Amount.

(a) At least three, but no more than five, Business Days prior to the expected Closing Date, BBTS shall deliver to Southcross a written statement (the “Adjustment Statement”) setting forth BBTS’ preliminary, good faith determination of the Adjustment Amount (“BBTS’ Proposed Adjustment Amount”). The Adjustment Statement shall be prepared in accordance with this Agreement and shall be based upon actual information available to BBTS at the time of preparation and upon BBTS’ good faith estimates and assumptions as to amounts not known by BBTS at such time.

(b) If Southcross has any questions or disagreements regarding the Adjustment Statement, then, upon request by Southcross prior to the Closing Date, BBTS and Southcross shall in good faith attempt to resolve any disagreements promptly, and BBTS shall afford Southcross the opportunity to examine the Adjustment Statement and such supporting schedules, analyses and workpapers on which the Adjustment Statement is based or from which the Adjustment Statement is derived as are reasonably requested by Southcross. If Southcross and BBTS agree on changes to BBTS’ Proposed Adjustment Amount based on such discussions, then the amount of Preferred Equity to be issued at Closing shall be based on such changes. If Southcross and BBTS do not agree on changes to BBTS’ Proposed Adjustment Amount, then the amount of Preferred Equity to be issued at Closing shall be based on the amounts set forth in the Adjustment Statement. In either such case, appropriate adjustments to the amount of Preferred Equity issued at Closing shall be made after the Closing pursuant to Section 2.7. BBTS’ Proposed Adjustment Amount, as modified to reflect changes (if any) agreed to pursuant to this Section 2.6(b), is referred to herein as the “Estimated Adjustment Amount.”

2.7 Post-Closing Adjustments to the Adjustment Amount.

(a) As promptly as practicable, but in no event later than 60 days after the Closing Date, Southcross shall deliver to BBTS a statement of Southcross’ calculation of the actual Adjustment Amount and such supporting documentation as is reasonably necessary to support the Adjustment Amount shown therein (the “Final Adjustment Statement”). To the extent reasonably necessary to Southcross, the Company shall give personnel, accountants and representatives of Southcross reasonable access to the books,

records and properties of the Company and its Subsidiaries for purposes of preparing the Final Adjustment Statement and will cause appropriate personnel of the Company to assist Southcross and Southcross’ personnel, accountants and representatives, with no charge to Southcross for such assistance, in the preparation of the Final Adjustment Statement.

(b) The Final Adjustment Statement shall become final and binding on the Parties as to the Adjustment Amount 30 days following the date the Final Adjustment Statement is received by BBTS, except to the extent that prior to the expiration of such 30-day period BBTS shall deliver to Southcross written notice (“Dispute Notice”), as hereinafter described, of its disagreement with the contents of the Final Adjustment Statement. Such Dispute Notice shall be in writing and set forth all of BBTS’ disagreements with respect to any portion of the Final Adjustment Statement, together with BBTS’ proposed changes thereto, and shall include an explanation in reasonable detail of, and such supporting documentation as is reasonably necessary to support, such changes. Any disagreements with or changes to the Final Adjustment Statement not included in such Dispute Notice shall be waived by BBTS.

(c) If BBTS has timely delivered a Dispute Notice to Southcross in the manner required above, then, upon written agreement between BBTS and Southcross resolving all disagreements with the contents of the Final Adjustment Statement set forth in the Dispute Notice, the Final Adjustment Statement (including any revisions thereto as are so agreed) will become final and binding on the Parties as to the Adjustment Amount.

(d) If the Final Adjustment Statement has not become final and binding 60 days following the date the Final Adjustment Statement is delivered to BBTS, then BBTS and Southcross shall submit any unresolved disagreements of BBTS set forth in the Dispute Notice to the Audit Firm for a final and binding determination and BBTS and Southcross shall execute such engagement, indemnity and other agreements as such Audit Firm may reasonably require in connection with or as a condition to such engagement. BBTS and Southcross shall cooperate diligently with any reasonable request of the Audit Firm and furnish to the Audit Firm such workpapers and other documents and information relating to such objections as the Audit Firm may reasonably request and are available to such Party or its Affiliates (or its independent public accountants) and will be afforded the opportunity to present to the Audit Firm any material relating to the determination of the matters in dispute and to discuss such determination with the Audit Firm prior to any written notice of determination hereunder being delivered by the Audit Firm. The Audit Firm’s engagement shall be limited to the resolution of designated items set forth in the Final Adjustment Statement that were identified in such Dispute Notice delivered by BBTS to Southcross in accordance with Section 2.7(b) and that remain in dispute upon the engagement of the Audit Firm, which resolution shall be in accordance with this Agreement. To the extent that a value has been assigned to any objection that remains in dispute, the Audit Firm shall not assign a value to such objection that is greater than the greatest value for such objection claimed by a Party or less than the smallest value for such objection claimed by a Party. The decision of the Audit Firm shall be set forth in a written statement delivered to Southcross and BBTS and shall be final and binding on the Parties, absent fraud or manifest error. Judgment may be entered on the decision of the Audit Firm in any court of competent jurisdiction.

(e) The proposed Final Adjustment Statement, in the form agreed to by the Parties as final, in the form deemed final in accordance with Section 2.7(b) or as revised, if necessary, to reflect the final determination by the Audit Firm, as applicable, shall be deemed the “Final Adjustment Statement,” and the Adjustment Amount as determined in accordance therewith is referred to herein as the “Final Adjustment Amount.”

(f) If (i) the Final Adjustment Amount exceeds the Estimated Adjustment Amount, then the Company shall issue to BBTS, effective as of the Closing Date, additional Preferred Equity valued at the amount of such excess or (ii) the Estimated Adjustment Amount exceeds the Final Adjustment Amount, then the Preferred Equity issued to BBTS at Closing shall be reduced (by redemption or otherwise) to reflect the Final Adjustment Amount.

(g) Any actions required by Section 2.7(f) with respect to the Preferred Equity shall be taken within three Business Days after the final determination of the Final Adjustment Statement pursuant to this Section 2.7.

(h) If the Parties submit any disputed amounts to the Audit Firm for resolution as provided in Section 2.7(d) above, the fees and expenses of the Audit Firm (the “Audit Fees”) will be paid by and apportioned between BBTS and Southcross based on the aggregate dollar amount of the dollar value difference in the aggregate between BBTS’ and Southcross’ proposed Adjustment Amounts on the Final Adjustment Statement and inversely related to the relative recovery of Southcross and BBTS, respectively, as determined by the Audit Firm. For example, if the aggregate dollar amount of the amount in dispute is $1,000,000 and the relative recovery of Southcross and BBTS as determined by the Audit Firm is $900,000 and $100,000, respectively, then BBTS will be apportioned 90% of the Audit Fees and Southcross will be apportioned 10% of the Audit Fees. Southcross and BBTS shall promptly, and in any event within five Business Days after the final determination of the Final Adjustment Statement, pay to the Audit Firm the amount of Audit Fees payable respectively by Southcross and BBTS pursuant to this Section 2.7(h).

From the date hereof until the Closing Date, upon discovery thereof, each Party shall provide prompt written notice to the other Party of (a) in the case of BBTS, the occurrence, or failure to occur, of any event of which to the Knowledge of BBTS causes or would be reasonably likely to cause the condition in Section 2.3(a) to fail to be satisfied or the failure of BBTS to comply with or satisfy in any material respect any covenant or agreement to be complied with by it hereunder prior to Closing and (b) in the case of Southcross, the occurrence, or failure to occur, of any event of which to the Knowledge of Southcross causes or would be reasonably likely to cause the condition in Section 2.2(a) to fail to be satisfied or the failure of Southcross to comply with or satisfy in any material respect any covenant or agreement to be complied with by it hereunder prior to Closing. The delivery of any notice pursuant to this Section 8.5 shall be for informational purposes only, and shall not in any way be deemed to cure any inaccuracy or breach of any provision of this Agreement or in any way limit or affect any rights or remedies under this Agreement (including rights to indemnification).

8.6 Conditions.

obligations under this paragraph), (c) engage in any negotiations or discussions with any Person relating to or (d) enter into any Contract or otherwise cooperate in any way with any other Person in connection with, in each case, any acquisition, equity investment, merger, recapitalization, liquidation, dissolution or similar transaction involving all or any portion of the assets of such Party or any of its Subsidiaries or all or any portion of the Equity Interest of such Party or any of its Subsidiaries without first obtaining the written approval of the other Parties.

8.10 Publicity.

If a Party is required by Law or listing agreement with a national security exchange or the rules of such exchange to make any release concerning any Operative Document or the Transactions, then such Party agrees to use its commercially reasonable efforts to: (a) provide advance notice of at least two Business Days to the other Parties of such release, which such notice shall include the content of such release, and (b) incorporate the reasonable comments proposed by the non-issuing Party.

8.11 Confidentiality. The Parties shall maintain in confidence the terms and conditions of this Agreement and each other Operative Document in accordance with the terms of the Confidentiality Agreement, the terms of which shall remain in full force and effect and shall be applicable to the Parties as if each such Party had been a signatory thereto.

If the Closing occurs, the Confidentiality Agreement shall terminate (which termination shall be effective as of the Closing).

8.12 Right of First Offer for Excluded TexStar Assets.

(a) If at any time BBTS proposes to sell, transfer, assign, convey, gift, exchange or otherwise dispose (other than to an Affiliate of BBTS) (“Transfer”) of any asset that is an Excluded TexStar Asset, then the Company, or any Person designated by the Company, shall have a right of first offer relating to such assets and BBTS shall deliver written notice (the “Transfer Notice”) to the Company specifying the asset(s) to be Transferred (the “Offered Assets”), stating BBTS’ bona fide intention to Transfer such Offered Assets and, if known, the identity of any prospective transferees.

(b) The Transfer Notice shall constitute BBTS’ offer to Transfer the Offered Assets to the Company or its designee, which offer shall be irrevocable for a period of 45 Days (the “ROFO Notice Period”). By delivering the Transfer Notice, BBTS represents and warrants to the Company and any designee thereof that (i) BBTS has full right, title and interest in and to the Offered Assets, (ii) BBTS has all the necessary power and authority and has taken all necessary action to sell such Offered Assets as contemplated by this Section 8.12 and (iii) the Offered Assets will be conveyed free and clear of any and all Encumbrances (other than Permitted Encumbrances).

(c) Upon receipt of the Transfer Notice, the Company or any designee thereof shall have until the end of the ROFO Notice Period to offer to purchase all (but not less than all) of the Offered Assets by delivering a written notice (a “ROFO Offer Notice”) to BBTS stating that it offers to purchase such Offered Assets and setting forth the material terms and conditions upon which the Company or any designee thereof will purchase the Offered Assets, including the proposed purchase price (which price shall be payable solely in cash at the closing of the transaction). Any ROFO Offer Notice so delivered shall be binding on the Company upon delivery and shall be irrevocable by the Company.

(d) If the Company does not deliver a ROFO Offer Notice in accordance with Section 8.12(c), BBTS may, during the 120 day period following the expiration of the ROFO Notice Period (which period may be extended for a reasonable time not to exceed 180 days to the extent reasonably necessary to obtain any required approvals of any Governmental Authority) (the “Waived ROFO Transfer Period”), Transfer all of the Offered Assets to a third Person on terms and conditions no more favorable in the aggregate to such third Person than those set forth in the ROFO Offer Notice. If BBTS does not Transfer the Offered Assets within such period or, if such Transfer is not consummated within the Waived ROFO Transfer Period, the rights provided hereunder shall be deemed to be revived and the Offered Assets shall not be Transferred or offered to any Person unless first re-offered to the Company in accordance with this Section 8.12.

(e) BBTS and the Company agree that the terms and conditions of any sale of Offered Assets to the Company or its designee in accordance with this Section 8.12 will be memorialized in, and governed by, a written purchase and sale agreement between BBTS and the Company or its designee with customary terms and provisions for such a transaction. At the closing of any sale and purchase with the Company or its designee pursuant to this Section 8.12, BBTS shall deliver or cause to be delivered to the Company or its designee the Offered Assets free and clear of all Encumbrances (other than the Permitted Encumbrances), against receipt of the purchase price therefor by certified check or by wire transfer of immediately available funds.

8.13 Tax Matters.

(a) Closing of the Books. The Company shall, to the extent permitted under Law and each such entity’s Organizational Documents, cause each Contributed Entity to

allocate all items of income, gain, loss, deduction or credit attributable to the taxable period of the Contributed Entity in which the Closing occurs based on an interim closing of the Contributed Entity Company’s books as of the end of the Closing Date consistent with Section 8.13(c) (to the extent the Contributed Entity’s Tax period does not otherwise end on the Closing Date).

(b) Return Preparation and Tax Payment. SXE GP shall, at its sole cost and expense, prepare or cause to be prepared all Tax Returns of the Contributed Entities due after the Closing Date that relate to a Pre-Closing Tax Period, including a Straddle Period (the “Post-Closing Returns”), other than Tax Returns of, or that include, BBTS or any of its Affiliates other than members of the TexStar Group (the “Excluded Returns”). SXE GP shall timely file or cause to be timely filed all Post-Closing Returns (other than Excluded Returns) and timely pay, or cause the Contributed Entities to timely pay, all Taxes shown as due on such Post-Closing Returns, as finalized pursuant to this Section 8.13(b), provided however that (i)if the Southcross Contribution causes SXE to close its books on the Closing Date, federal income Tax Return of SXE for the short period (a) ending on the Closing Date shall be filed no later than January 21, 2015 (on extension), and (b) beginning the day immediately after the Closing Date shall be filed no later than January 31, 2015, and (ii) if the Southcross Contribution does not cause SXE to close its books, the SXE federal income Straddle Return shall be filed no later than January 31, 2015. BBTS shall prepare or cause to be prepared, and file or cause to be filed, the Excluded Returns at its cost and expense and shall remit the Tax shown to be due thereon to the appropriate Tax authority. The Post-Closing Returns and the TexStar Excluded Returns shall, to the extent permitted by applicable Law, be prepared on a basis consistent with existing procedures and practices and accounting methods of the applicable Contributed Entity, except for inconsistencies required by changes in Law or facts.

At least 20 days prior to the due date of any Post-Closing Return (other than any Excluded Return or any federal income Tax Return of SXE) that is an income or franchise Tax Return (including, for the avoidance of doubt, any Texas franchise tax return), or a reasonable period of time with respect to a Post-Closing Return that is a non-income or non-franchise Tax Return, or at least 10 days prior to the date any federal income Tax Return of SXE is filed, SXE GP shall submit a draft of such Post-Closing Returns (including Straddle Returns) for review and approval to both the BBTS Director and the Southcross Director. The Southcross Director and the BBTS Director shall each consider in good faith any comments made by the other Party, and shall attempt in good faith to resolve any disagreements regarding such Post-Closing Returns prior to the due date for filing. At least 20 days prior to the due date of any TexStar Excluded Return that is an income or franchise Tax Return (including, for the avoidance of doubt, any Texas franchise tax return), or a reasonable period of time with respect to a TexStar Excluded Return that is not an income or franchise Tax Return, BBTS shall submit a draft of such TexStar Excluded Returns to the Southcross Director for review and approval. Any approval pursuant to rights granted to a Person under this Section 8.13(b) shall not be unreasonably withheld, conditioned or delayed.

With respect to any such Post-Closing Return, the amount of undisputed Tax due with respect to such Pre-Closing Tax Period (as determined under Section 8.13(c) with respect to Straddle Periods) shall become a Redirected Distribution Amount with respect to the following Parties (the “Disputing Party”) (i) Southcross for Post-Closing Returns of SXE GP and the members of the SXE Group, and (ii) BBTS for Post-Closing Returns of the members of the TexStar Group. In the event of a dispute with respect to any such Post-Closing Return, the disputed amounts become a Redirected Distribution Amount of the Disputing Party promptly when such items in dispute are resolved pursuant Section 8.13(g). No amount treated as a Redirected Distribution Amount pursuant to this Section 8.13(b) shall excuse the Disputing Party from its indemnification obligations (if any) pursuant to Article X if the amount of Taxes as ultimately determined (on audit or otherwise) for the periods covered by such Pre-Closing Returns exceeds the amount of the Redirected Distribution Amount under this Section 8.13(b). With respect to any Excluded Return that is for a Straddle Period, the Company shall pay to BBTS at least two days prior to the filing of such Excluded Return, the amount of undisputed Tax due with respect such Excluded Return that is attributable to a Post-Closing Tax Period (as determined under Section 8.13(c)). In the event of a dispute with respect to any such Excluded Return, the disputed amounts attributable to the Company shall become payable by the Company to BBTS promptly when such items in dispute are resolved pursuant to Section 8.13(g).

In the event that at least five days prior to the due date for filing (or, with respect to any federal income Tax Return of SXE, at least five days prior to the date such Tax Return is filed) (the “Disputed Return Date”) (i) any Post-Closing Return, SXE GP and the party or parties entitled to approve such return pursuant to Section 8.13(b) are unable to resolve any dispute with respect to such Post-Closing Return, or (ii) any TexStar Excluded Return that is a Straddle Return, the Southcross Director and BBTS are unable to resolve any dispute with respect to any such return, such dispute shall be resolved pursuant to Section 8.13(g), which resolution shall be binding on the Parties.

(c) Straddle Period Tax Returns. To the extent permissible under applicable Laws, the Company shall elect to have each taxable period of the Contributed Entities (other than SXE) during which the Closing Date occurs end at the end of the Closing Date and, if such election is not permitted or required in a jurisdiction such that any of the Contributed Entities is required to file a Tax Return for a Straddle Period, the Company shall use the following conventions for determining the amount of Taxes attributable to the Pre-Closing Tax Period: (i) in the case of property Taxes and other similar Taxes imposed on a periodic basis, the amount attributable to the Pre-Closing Tax Period shall be determined by multiplying the Taxes for the entire Straddle Period by a fraction, the numerator of which is the number of days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of days in the entire Straddle Period; and (ii) in the case of all other Taxes (including income Taxes, sales Taxes, employment Taxes, withholding Taxes and other transaction based Taxes) to the extent the Contributed Entity’s Organizational Documents permit, the amount attributable to the Pre-Closing Tax Period shall be determined using a “closing of the books methodology”; provided, however, with respect to SXE, the amount of federal and state income Taxes shall be allocated based on a pro rata basis using the conventions set forth

in the SXE Partnership Agreement. For purposes of clause (ii), any item determined on an annual or periodic basis (including amortization and depreciation deductions) shall be allocated to the Pre-Closing Tax Period by multiplying the amount of such item for the entire Straddle Period by a fraction, the numerator of which is the number of days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of days in the entire Straddle Period, with such reasonable adjustments as may be necessary to appropriately take the items into account (e.g., to appropriately reflect the period during which depreciable property was in service).

(d) Tax Contests. If the Company or any member Contributed Entity receives notice of any deficiency, proposed adjustment, assessment, audit, examination, inquiry, suit, dispute or other claim with respect to any Pre-Closing Taxes (a “Tax Claim”), the Company will cause such entity to notify in writing within ten days of receipt of any Tax Claim the Southcross Director and the BBTS Director, but the failure to so notify will not relieve the BBTS or Southcross, as applicable, of any liability it may have under Section 10.1(b)(iii) or Section 10.2(b)(iii), except to the extent such Party has suffered actual and material prejudice thereby. With respect to any Tax Claim, the provisions of this Section 8.13(d) and not Section 10.4 or Section 10.5 shall apply.

With respect to any Tax Claim, the following Person (the “Controlling Person”) shall assume and control all claims, actions, administrative appeals, proceedings, hearings and conferences, investigations or inquiries, suits with any applicable Governmental Authorities with respect thereto (the “Tax Proceedings”) (i) the Southcross Director with respect to a Tax Claim attributable to SXE GP and any member of the SXE Group, or (ii) the BBTS Director with respect to a Tax Claim attributable to a member of the TexStar Group. With respect to any Tax Claim, the Controlling Person may either pay the Tax claimed and ▇▇▇ for a refund where applicable Law permits such refund suits or contest the Tax Claim in any permissible manner; provided, however, that (A) the Person, as between the Southcross Director and the BBTS Director, who is not the Controlling Person as to a Tax Claim (the “Non-Controlling Person”) will be permitted to participate fully in all such Tax Proceedings at such Person’s sole cost and the Controlling Person will consult in good faith with the Non-Controlling Person in the negotiation and settlement of any Tax Claim, and (B) the Controlling Person will not, without the written consent of the Non-Controlling Person (which consent shall not be unreasonably withheld) settle or compromise any Tax Claim in any manner; provided, that to the extent that a Tax Claim relates to a Straddle Period, the Southcross Director and the BBTS Director will jointly have the right to control all Tax Proceedings taken in connection with any such Tax Claim and such Straddle Period Tax Claim will not settle or compromise such Straddle Period Tax Claim, without the written consent of both the Southcross Director and the BBTS Director, which consents shall not be unreasonably withheld, conditioned or delayed.

(e) Cooperation on Tax Matters. Southcross and BBTS shall (and the Company shall cause the Contributed Entities to) (i) assist in the preparation and timely filing of all Tax Returns of the Contributed Entities; (ii) assist in any audit or other proceeding with respect to the Tax Returns or Taxes of the Contributed Entities (whether or not involving a Tax contest); (iii) make available any information, records or other

documents relating to any Taxes or Tax Returns of the Contributed Entities (including copies of Tax Returns and related work papers) with respect to a Pre-Closing Tax Period; and (iv) provide certificates or forms, and timely execute any Tax Returns, that are necessary or appropriate to establish an exemption for (or reduction in) any Tax. Without limiting the foregoing, BBTS agrees to provide to the Company no later than March 1, 2015, the following information as of the Closing Date (i) the tax basis of all assets and the amount of liabilities of the members of the TexStar Group; (ii) the amount of any tax items under Section 704(c) of the Code with respect to assets of the members of the TexStar Group; and (iii) to the extent reasonably available, such other information as the Company may reasonably request in writing for purposes of complying with its applicable tax reporting requirements. Neither the Company or SXE GP shall, nor shall they allow the Contributed Entities to, amend any Tax Return of any of the Contributed Entities for a Pre-Closing Tax Period or otherwise initiate any other Post-Closing Tax Event without the prior written consent of (i) the Southcross Director, with respect to a Post-Closing Tax Event of SXE GP or any member of the SXE Group, or (ii) the BBTS Director, with respect to a Post-Closing Tax Event of any members of the TexStar Group.

(f) Refunds. Any refund of Taxes of the Contributed Entities, including any interest with respect thereto, attributable to any Tax period occurring on or before the Closing Date (or attributable to the portion of any Straddle Period ending on the Closing Date determined in a manner specified in Section 8.13(c)) shall be for the account of (i) Southcross, with respect to Tax refunds relating to SXE GP or any member of the SXE Group, and (ii) BBTS, with respect to Tax refunds relating to any member of the TexStar Group. If the amount of any such Tax refund is received by the Company or any of the Contributed Entities, such refund shall be paid promptly to the appropriate Party consistent with this Section 8.13(f).

(g) Disputes. If a dispute arises under Section 8.13(b) with respect to approval of a Tax Return, then within 20 days after the Disputed Return Date, the disagreeing parties shall submit any unresolved disagreements to the Audit Firm for a final and binding determination and the disagreeing parties shall execute such engagement, indemnity and other agreements as such Audit Firm may reasonably require in connection with or as a condition to such engagement. The party failing to approve the Tax return in question shall provide in writing all of such party’s disagreements to the Audit Firm within two days of the submission of the disagreement to the Audit Firm, with respect to any portion of the disputed return, together with proposed changes thereto, and an explanation in reasonable detail of, and such supporting documentation as is reasonably necessary to support, such changes. The disagreeing parties shall cooperate diligently with any reasonable request of the Audit Firm and furnish to the Audit Firm such workpapers, schedules, calculations, analysis and other documents and information relating to such objections as the Audit Firm may reasonably request and are available to such disagreeing party or its Affiliates (or its independent public accountants) and will be afforded the opportunity to present to the Audit Firm any additional material relating to the determination of the matters in dispute and to discuss such determination with the Audit Firm prior to any written notice of determination hereunder being delivered by the Audit Firm. The Audit Firm’s engagement shall be limited to the resolution of designated items of the disputed Tax Return arising under Section 8.13(b). The decision of the Audit

Firm shall be set forth in a written statement delivered to the disagreeing parties and shall be final and binding on such parties, absent fraud or manifest error. Judgment may be entered on the decision of the Audit Firm in any court of competent jurisdiction. The fees and expenses of the Independent Auditor shall be borne in the same manner and based on the same principles provided in Section 2.7(h).

(h) Tax Characterization of Transaction. The Parties acknowledge and agree that the transactions hereunder may cause a tax termination of SXE for U.S. federal income tax purposes under Section 708 of the Code. If such termination occurs, SXE will have two short period Tax Returns for U.S. federal income tax purposes for the 2014 calendar year, one for the period from January 1, 2014 through and including the Closing Date and one for the period beginning on the day after the Closing Date. The Parties shall treat (i) the Southcross Contribution and the BBTS Contribution as transactions described in Section 721(a) of the Code, (ii) the payments to Southcross and BBTS pursuant to Section 2.5(h) as distributions pursuant to a plan of a portion of the proceeds of the Credit Facility to Southcross and BBTS as described in Treasury Regulations Section 1.707-5(b)(2)(ii)(A), and (iii) the assumption of the Assumed Debt Amount pursuant to Section 2.5(g) as an assumption of a “qualified liability” pursuant to Treasury Regulation Section 1.707-5(a). The Parties shall not adopt positions inconsistent with the characterization or treatment described in this Section 8.13(h) in any Tax Return or Tax contest, except to the extent a change in Tax Law requires a different characterization. Unless otherwise required by applicable Law, the Parties agree that all indemnification payments made pursuant to Section 10.1(b) and Section 10.2(b) will be treated by the Parties and reflected on their Tax Returns as a reimbursement to the Company to restore the value of the contributions made by the payee Limited Partner as of the Closing Date, and such payment shall neither increase such Partner’s Capital Account (as defined in the LP Agreement) nor affect the Sharing Percentages (as defined in the LP Agreement).

(i) Termination of Tax Sharing Agreements.

(a) All of the representations, warranties, covenants and agreements of the Parties contained in this Agreement and any and all claims and causes of action for indemnification under this Article X shall survive as follows (with the date on which the relevant representation, warranty, covenant or agreement expires pursuant to this Section 10.3 being the “Expiration Date”):

(i) the representations and warranties set forth in (A) Sections 4.1, 4.2, 4.4, 4.5, 4.8, 5.1, 5.2, 5.16, 6.1, 6.2, 6.4, 6.5, 6.7, 7.1, 7.2 and 7.16 shall survive indefinitely and (B) Sections 5.10, 5.18, 7.10 and 7.18 shall survive for a period ending 60 days after the expiration of the statute of limitations applicable to any matters or other liabilities that are the subject thereof (together, the representations and warranties set forth in clauses (A) and (B), except for those set forth in Sections 5.18 and 7.18, the “Fundamental Representations”), and any covenants or agreements in this Agreement that by their terms are to be performed after the Closing shall survive until fully discharged; and

10.4 Third Person Claims.

(a) If any Southcross Indemnitee, TexStar Indemnitee or Company Indemnitee (any such Person, an “Indemnified Party”) has received notice or otherwise has knowledge of any claim by any Person who is not a Party or the commencement of any Proceeding by such Person who the Indemnified Party believes in good faith has an indemnifiable claim under this Agreement (a “Third Person Claim”), the Indemnified Party shall deliver a Claim Notice with respect thereto to the Party obligated to provide indemnification pursuant to Section 10.1 or Section 10.2 (the “Indemnifying Party”); provided, however, that the failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party from liability for such Third Person Claim except to the extent that such failure or delay results in the loss or forfeiture by the Indemnifying Party of material rights and defenses otherwise available to the Indemnifying Party with respect to such Third Person Claim or increased indemnification expenses incurred as a direct result of such failure or delay to so notify. The Claim Notice shall state the nature and the basis of such Third Person Claim. The Indemnifying Party shall have the right to defend and settle any such Third Person Claim, at its own expense and by its own counsel (reasonably acceptable to the Indemnified Party) if the Indemnifying Party provides written notice to the Indemnified Party (within five Business Days of its receipt of the Claim Notice) declaring its intention to defend or settle such Third Person Claim and acknowledging its obligations to indemnify the Indemnified Party with respect to such Third Person Claim in accordance with this Article X.

(b) If the Indemnifying Party notifies the Indemnified Party of its intention to undertake the defense or settlement of such Third Person Claim pursuant to Section 10.4(a), the Indemnified Party shall cooperate with the Indemnifying Party and its counsel, at the Indemnifying Party’s sole cost and expense, in all commercially reasonable respects in the defense thereof and in any settlement thereof. Such cooperation shall include furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake the defense or settlement of such Third Person Claim pursuant to Section 10.4(a), the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such Third Person Claim; provided, however, that the Indemnified Party shall be entitled, at its expense, to participate in the defense of such Third Person Claim and the negotiations of the settlement thereof.

(c) The Indemnifying Party shall not settle any Third Person Claim without the consent of the Indemnified Party unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party, and the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, the Indemnified Party and further involves no injunction or equitable relief upon the Indemnified Party and no limitation on the future operation of the business, assets or property of the Company, its Subsidiaries or their respective Affiliates.

(d) If, upon receiving a Claim Notice with respect to a Third Person Claim, the Indemnifying Party does not timely undertake to defend such Third Person Claim, or fails to pursue such defense diligently or is otherwise not entitled to assume the defense of such Third Person Claim or the Indemnified Party is otherwise entitled to assume such defense, the Indemnified Party may undertake such defense through counsel of its choice, at the cost and expense of the Indemnifying Party, and the Indemnified Party may settle such Third Person Claim, in its discretion, and the Indemnifying Party shall reimburse the Indemnified Party for the amount paid in such settlement and any other Losses incurred by the Indemnified Party in connection therewith.

10.5 Direct Claims.

(a) If the Indemnified Party asserts the existence of a claim giving rise to Losses that is not a Third Person Claim (a “Direct Claim”), the Indemnified Party shall deliver a Claim Notice with respect thereto to the Indemnifying Party. If the Company, as an Indemnified Party hereunder, suffers an indemnifiable Loss, the Party that is not responsible for such Loss is hereby granted all power and authority to cause the Company to bring a Direct Claim and make decisions on behalf of the Company as an Indemnified Party hereunder.

(b) A Claim Notice delivered in connection with a Direct Claim shall state that it is being given pursuant to this Section 10.5 and shall specify the nature and, if known, the amount of the Losses associated therewith. If the Indemnifying Party, within 30 days after the receipt of such Claim Notice from the Indemnified Party, shall not give written notice to the Indemnified Party stating the Indemnifying Party’s intent to contest such Direct Claim, the Indemnified Party’s assertion shall be deemed accepted and the amount of such Direct Claim shall be deemed a valid Direct Claim.

(c) If, however, the Indemnifying Party contests such Direct Claim by giving written notice, setting forth in reasonable detail the basis for contesting the Direct Claim, to the Indemnified Party within such 30-day period, then the Indemnifying Party and the Indemnified Party shall negotiate in good faith to reach agreement regarding such Direct Claim. If the Indemnifying Party and the Indemnified Party cannot reach an agreement regarding such Direct Claim within 30 days after the notice contesting such Direct Claim provided by the Indemnifying Party has been received by the Indemnified Party, the Indemnifying Party shall be deemed to have rejected such Direct Claim, in which case the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.

10.6 Basket; Indemnification Cap.

(a) An Indemnifying Party shall not have any obligation to provide indemnification for Losses arising out of breaches of the Non-Fundamental Representations (“Covered Losses”) except to the extent that the aggregate amount of all Covered Losses exceeds (i) in the event that BBTS is the Indemnifying Party, $5,500,000 and (ii) in the event that Southcross is the Indemnifying Party, $2,312,500 (each of (i) and (ii), as applicable, the “Basket”) in which case the Indemnifying Party

shall be liable under this Article X only for Covered Losses that exceed the Basket. The Basket shall not be applicable to Losses arising out of breaches of the Fundamental Representations, Section 5.5(b) or Section 7.5(b).

(b) The maximum amount for which a Party may be liable, other than in cases of knowing and intentional fraud or willful misconduct, in respect of breaches of any of the Non-Fundamental Representations, shall be limited to an amount equal to (i) in the event that BBTS is the Indemnifying Party, $82,500,000 and (ii) in the event Southcross is the Indemnifying Party, $34,687,500, and in respect of any breaches of the Fundamental Representations or any other covenant or agreement under this Agreement, shall be limited to an amount equal to the Contribution Consideration applicable to such Party. Notwithstanding the foregoing, there shall be no maximum amount for which a Party may be liable in connection with such Party’s breach of Section 5.5(b) or Section 7.5(b), as applicable.

10.7 Calculation of Losses. In calculating amounts payable to any Indemnified Party for a claim for indemnification hereunder, the amount of any indemnified Losses shall be determined without duplication of any other Loss for which an indemnification claim has been made or could be made under any other representation, warranty, agreement or covenant and shall be computed net of payments actually recovered by the Indemnified Party (or its Affiliates) under any insurance policy with respect to such Losses.

10.8 Other Limitations.

(a) Waiver of Certain Damages. Notwithstanding any other provision of this Agreement, no Party shall be liable for punitive, special, indirect, exemplary, consequential, remote or speculative damages of any kind or nature or any damages calculated using diminution of value or any multiple of value, regardless of the form of action through which such damages are sought, except (A) for any such damages recovered by any Person who is not a Party against an Indemnified Party in respect of which such Indemnified Party would otherwise be entitled to indemnification pursuant to the terms hereof and (B) in the case of consequential damages to an Indemnified Party arising from knowing and intentional fraud or willful misconduct.

(b) Sole and Exclusive Remedy. Except for the indemnity obligations described in Section 8.13, or the assertion of any claim based on knowing and intentional fraud or willful misconduct or with respect to the determination of the Final Adjustment Amount pursuant to Section 2.7, the remedies provided in this Article X shall be the sole and exclusive legal remedies of the Parties from and after the Closing with respect to this Agreement and the Transactions expressly contemplated by this Agreement. This Article X shall not govern the remedies available under any other Operative Document to which a Party is party or in respect of the Related Transactions and nothing contained in this Agreement shall limit the ability of any Party (or any of its Affiliates) to pursue any remedy under the Operative Documents (excluding this Agreement). Subject to the rights of the parties to the SXE Commitment Letter under the terms thereof, none of the Parties, nor or any of their respective affiliates, shall have any rights or claims against the Debt Financing Sources in connection with the SXE Credit Facility described in the SXE Commitment Letter, whether at law or equity, in contract, in tort or otherwise.

(c) No Duplication. No Southcross Indemnitee shall be entitled to indemnification under this Article X in respect of any matter to the extent such matter is taken into account in the determination of the amount of Preferred Equity to be issued at Closing or for any variations in any amount reflected in (including as a result of a determination by the Audit Firm) in the determination of the Final Adjustment Amount pursuant to Section 2.7.

(d) For purposes of determining whether a representation or warranty has been breached for purposes of this Article X and determining the amount of Losses suffered by any TexStar Indemnitee or Southcross Indemnitee, as the case may be, each representation and warranty set forth in this Agreement, and any qualification with respect to any representation or warranty set forth in the Schedules, shall be read without regard or giving effect to any “material,” “materiality” or “Material Adverse Effect” qualifications that may be contained in any such representation or warranty.

10.9 Payment of Indemnification by a Party. The sole and exclusive remedy of any Indemnified Party for any Losses under Section 10.1 or Section 10.2, as applicable, shall be as set forth in this Section 10.9:

(a) Upon (i) any Southcross Indemnitee or Company Indemnitee becoming entitled to any Losses pursuant to any claim for indemnification under Section 10.1 or (ii) any TexStar Indemnitee or Company Indemnitee becoming entitled to any Losses pursuant to any claim for indemnification under Section 10.2, the Southcross Indemnitee, the Company Indemnitee or the TexStar Indemnitee, as applicable, shall give written notice (an “Indemnity Notice”) thereof (which notice shall state the amount of such Losses) to BBTS or Southcross, as applicable. At any time on or prior to 30 days after BBTS’ or Southcross’ receipt, as applicable, of an Indemnity Notice (“CP Deadline”), BBTS or Southcross, as applicable, shall have the right, at its option and sole discretion, to deliver to the Company, by check or wire transfer of immediately available funds, cash in an amount up to the amount of the Losses with respect to which such Indemnity Notice has been given (“Subject Losses”).

(b) To the extent BBTS or Southcross, as applicable, delivers cash to the Company pursuant to this Section 10.9 on or before the CP Deadline, such Subject Losses shall be reduced dollar for dollar by the amount of such cash so paid and shall be deemed satisfied to the extent of such payment and (i) in the case of such payment by BBTS, neither the Southcross Indemnitees nor the Company Indemnitees shall have any further rights under this Agreement with respect to such Subject Losses to the extent so satisfied and (ii) in the case of such payment by Southcross, neither the TexStar Indemnitees nor the Company Indemnitees shall have any further rights under this Agreement with respect to such Subject Losses to the extent so satisfied, in each case, absent knowing and intentional fraud on the part of BBTS or Southcross, as applicable.

(c) If BBTS or Southcross, as applicable, shall not have paid to the Company cash in the full amount of such Subject Losses on or before the CP Deadline applicable to such Subject Loss (the amount by which the Subject Losses exceed the amount of cash so paid by BBTS or Southcross, as applicable, the “Adjustment Loss”), such Adjustment Loss shall be satisfied in accordance with Section 4.5, Section 5.1(b) and Section 5.1(c) of the LP Agreement, as applicable.

(d) Any amounts paid, either in cash or in accordance with Section 4.5, Section 5.1(b) and Section 5.1(c) of the LP Agreement, as applicable, shall not have any effect on the Capital Accounts (as defined in the LP Agreement) of Southcross or BBTS (or their respective collective assignees) applicable to such Person as a partner of the Company.

11.1 Governing Law; Venue; Waiver of Jury Trial.

(a) This Agreement shall be governed by and construed and interpreted in accordance with the Laws of the State of Texas, without giving effect to any conflicts of law provision or rule (whether of the State of Texas or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Texas.

The Parties hereby irrevocably waive, to the fullest extent permitted by Law, any objection which they may now or hereafter have to the laying of venue of any dispute arising out of or relating to this Agreement or any of the Transactions brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each Party agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. This consent to jurisdiction is being given solely for purposes of this Agreement and is not intended to, and shall not, confer consent to jurisdiction with respect to any other dispute in which a Party to this Agreement may become involved.

(c) EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, IN EACH CASE, INCLUDING ANY DISPUTE ARISING OUT OF OR RELATED TO THE SXE COMMITMENT LETTER OR THE PERFORMANCE THEREOF.

(d) Notwithstanding anything in this Section 11.1 to the contrary, each of the Parties agrees that it will not bring or support any action or proceeding (whether at law, in equity, in contract, in tort or otherwise) against any Commitment Party (as defined in the SXE Commitment Letter), any Lender (as defined in the SXE Commitment Letter), any affiliate of a Commitment Party or a Lender or any other Person that has committed to provide or otherwise entered into agreements in connection with the SXE Commitment Letter or the financings related thereto in connection with the transactions contemplated hereby (each such Person, a “Debt Financing Source”, and, collectively, the “Debt Financing Sources”) in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including any dispute arising out of or relating in any way to the SXE Commitment Letter or the performance thereof, in any forum other than the Supreme Court of the State of New York, County of New York, or, if under applicable law exclusive jurisdiction is vested in the Federal courts, the United States District Court for the Southern District of New York (and appellate courts thereof).

11.2 Third-Party Beneficiaries. Nothing in this Agreement shall provide any benefit to any third Person or entitle any third Person to any claim, cause of action, remedy or right of any kind, it being the intent of the Parties that this Agreement shall not be construed as a third-party beneficiary contract; provided, however, that the indemnification provisions of Article X shall inure to the benefit of the Southcross Indemnitees and the TexStar Indemnitees as provided therein; provided that each of the Debt Financing Sources are third-party beneficiaries of this Agreement with respect to the provisions in this Section 11.2 and provisions in Sections 10.8, 11.1 and 11.6 of this Agreement regarding venue, jury waiver, recourse and amendment of this Contribution Agreement to the extent related to the Debt Financing Sources.

By way of clarification, no such assignment by BBTS shall affect the release and related agreements of BBTS set forth in Section 8.15, which shall remain in effect notwithstanding such assignment. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns.

11.5 Entire Agreement. This Agreement, the other Operative Documents and the Confidentiality Agreement collectively constitute the sole understanding of the Parties with respect to the subject matter hereof; provided, however, that this provision is not intended to abrogate any other written agreement between or among the Parties executed before or with this Agreement that relates to any subject matter other than the Transactions.
