The arbitrator(s) shall be selected by mutual agreement of the parties, if possible. If the parties fail to reach agreement upon appointment of arbitrator(s) within thirty days following receipt by one party of the other party’s notice of desire to arbitrate, the arbitrator(s) shall be selected from a panel or panels of persons submitted by the AAA. The selection process shall be that which is set forth in the AAA Commercial Arbitration Rules then prevailing, except that, if the parties fail to select arbitrator(s) from one or more panels, AAA shall not have the power to make appointment(s) but shall continue to submit additional panels until arbitrator(s) have been selected. The jurisdiction of the arbitrator(s) and the arbitrability of any claim, defense, issue or objection raised by any party shall be decided by the arbitrator(s) in the first instance. Judgment on the award entered by the arbitrator(s) may be entered by any court having jurisdiction thereof. All aspects of the arbitration and matters subject thereto shall remain confidential. The parties will each bear their own attorneys’ fees and costs in connection with any dispute or controversy, except as provided in Section 5.6(c), below.

(c) In the event of a breach or threatened breach by any Seller Party of any of the provisions of this Section 5.6, Buyer shall have the right to seek interim relief from AAA pursuant to the Optional Rules for Emergency Measures of Protection contained in the Commercial Arbitration Rules of the AAA (including the arbitrator selection procedures provided for in such Optional Rules for Emergency Measures of Protection, which shall govern the selection of arbitrator(s) for purposes of this paragraph (c)) or from a court of competent jurisdiction. The Seller Parties acknowledge that Buyer will suffer irreparable damage or injury

-23-

not fully compensable by money damages, or the exact amount of which may be impossible to ascertain, and therefore will not have an adequate legal remedy. Accordingly, Buyer will be entitled to obtain any interim relief necessary or appropriate to prevent or curtail any such breach, threatened or actual, without the necessity of posting security or showing any actual damages or irreparable injury. Such interim relief may include, but is not limited to, (i) temporary or permanent injunctive relief for the enforcement of this Section 5.6, (ii) a decree for the specific performance of this Section 5.6 or (iii) Buyer’s reasonable attorneys’ fees, costs and expenses related to such interim relief; provided, however, that Buyer agrees to pay for any Seller Party’s reasonable attorneys’ fees, costs and expenses related to interim relief sought by Buyer in the event that the Seller Parties prevail and no such interim relief is granted. Such interim relief is in addition to any other rights Buyer may have, including the right to seek damages.

(d) Buyer and each Seller Party hereby agree that this Section 5.6 is a material and substantial part of the transactions contemplated by this Agreement. Each Seller Party further agrees and acknowledges that the covenants in this Section 5.6 are reasonable with respect to their duration, scope and geographical area.

(e) The covenants in this Section 5.6 are severable and separate, including within provisions, subparts or portions thereof, and the unenforceability of any specific covenant, provision or subpart thereof in this Section 5.6 is not intended by any party hereto to, and shall not, affect the provisions of any other covenant in this Section 5.6. If any arbitrator or panel of arbitrators, or any court pursuant to paragraph (c) above, determines that the terms, scope, time or territorial restrictions set forth in Section 5.6(a) are unreasonable as applied to a Seller Party, the parties hereto acknowledge their mutual intention and agreement that the offending provisions, subparts or portions thereof be severed and the remaining provisions and restrictions be enforced to the fullest extent permitted by law as the arbitrator(s) or court (pursuant to paragraph (c) above) deems reasonable, and thereby shall be reformed to that extent. All the covenants, provisions and subparts thereof in this Section 5.6 are intended by each party hereto to, and shall, be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of any Seller Party against Buyer, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by Buyer of any covenant, provision or subpart in this Section 5.6. The covenants contained in this Section 5.6 shall not be affected by any breach of any other provision hereof by any party hereto and shall not prevent Mr. Arlen B. Cenac, Jr., Cenac Towing or Cenac Offshore from rendering services to Buyer in accordance with the Transitional Operating Agreement, as amended by the Transitional Operating Agreement Amendment.

Section 5.7 Further Assistance. The Seller Parties shall execute, acknowledge and deliver or cause to be executed, acknowledged and delivered to Buyer or its Affiliates such assignments or other instruments of transfer, assignment and conveyance, in form and substance reasonably satisfactory to Buyer, as shall be necessary to vest in Buyer (or its permitted assignees) all of the right, title and interest in and to the Purchased Assets, free and clear of all Liens, or to better enable Buyer to complete, perform or discharge any of the Assumed Liabilities and any other document reasonably requested by Buyer in connection with this Agreement.

Section 5.8 Governmental Filings. As promptly as practicable after the execution of this Agreement, and in any event within ten (10) days after the execution of this Agreement, each party shall, in cooperation with the other, file any reports or notifications that may be required to be filed by it under applicable Law, including any filings or notifications required under the HSR Act.

The Seller Parties shall use reasonable efforts to (i) secure, as soon as practicable after the date hereof, all approvals or consents of third Persons as may be necessary to enable them to consummate the transactions contemplated by the Transaction Documents (ii) satisfy, on or before the Closing Date, the conditions Section 8.1 sets forth. Buyer shall use reasonable efforts to (i) secure, as soon as practicable after the date hereof, all approvals or consents of third Persons as may be necessary to enable Buyer to consummate the transactions contemplated by the Transaction Documents and (ii) satisfy, on or before the Closing Date, the conditions Section 8.2 sets forth. After the Closing, the Seller Parties shall use reasonable efforts to obtain any approvals or consents or assist in any filings required in connection with the transactions contemplated by the Transaction Documents that are requested by Buyer and that have not been previously obtained or made.

Section 5.10 Public Announcements. Neither the Seller Parties nor Buyer shall, without the prior approval (which may not be unreasonably withheld, delayed or conditioned) of Buyer or the Seller, as the case may be, issue, or permit any of their partners, members, directors, managers, officers, employees, agents or Affiliates to issue, any press release or other public announcement with respect to this Agreement or the transactions contemplated hereby; provided that Buyer or the Partnership may issue any press release or make any other public announcement required by Law or by obligations pursuant to any listing agreement with any national securities exchange without obtaining any such approval.

Section 5.11 Income Tax Matters. Within 180 days after the Closing Date, the Seller and Buyer shall jointly prepare IRS Forms 8594 to report the allocations of the Purchase Price among the Purchased Assets

Section 5.12 Taxes Upon Conveyance and Transfer. The Seller shall be responsible for all sales, use, transfer or similar Taxes payable in connection with the sale, transfer and assignment of the Purchased Assets to Buyer; provided, however, that, within 30 days of payment by the Seller, Buyer shall reimburse the Seller for 100% of any such Taxes remitted by the Seller (i) in connection with a final assessment of such Taxes by a state or local taxing authority or (ii) with the written consent of Buyer. Buyer shall be entitled to any refunds of such Taxes remitted by the Seller for which Buyer has reimbursed the Seller, and the Seller shall make any required assignments or take any other necessary steps to ensure that Buyer has the right to pursue any refunds of such Taxes. The determination as to whether any position taken by a taxing authority with respect to the Taxes referenced in this Section 5.12 should be contested shall be made by Buyer, who shall control any such contest, proceeding or defense at its own expense. The Seller agrees to provide, at Buyer’s request, documentation evidencing the locations of the Vessels as of the Closing Date and to cooperate with Buyer with respect to any procedural steps required by the sales, use, transfer or similar Tax laws of any state or locality having taxing jurisdiction over the Vessels as of the Closing Date to document any exemptions from or reductions of such Taxes for which the transfer of the Vessels or other Purchased Assets

may be eligible, including the execution of exemption certificates or affidavits or the filing of any required returns or other forms with state or local taxing authorities.

Section 5.13 Other Taxes and Charges. The Seller shall be responsible for any Taxes arising out of or relating to the use and operation of the Purchased Assets, the operations of the Seller, or the Operations with respect to periods prior to the Closing. Any (i) property Taxes on the Purchased Assets and (ii) other Taxes, fees, costs or charges assessed on a similar periodic basis in respect of ownership or operation of the Purchased Assets shall be prorated through the Closing (based on estimates of the most recent amounts paid), with the Seller being responsible for all of such prorated charges attributable to the period prior to the Closing and Buyer being responsible for post-closing prorations. To the extent any bills for the items referred to in this Section 5.13 arise after the purchase price adjustments have been made under Section 1.5, promptly upon receipt of any such bill, Buyer or the Seller, as appropriate, shall provide the other with copies thereof for such items for which the other party is responsible pursuant to this Section, and the resulting amount payable by Buyer or the Seller shall be paid promptly upon demand by the party hereto to whom such payment is owed.

Section 5.14 Condition to Transfer of Contracts. Notwithstanding anything herein to the contrary, the parties hereto acknowledge and agree that at the Closing, the Seller is not assigning to Buyer any Contract or other right constituting a Purchased Asset which by its terms requires the consent of any other party unless such consent has been obtained prior to the Closing. With respect to each such unassigned Contract or right (collectively, “Purchased Rights”), after the Closing, the Seller shall continue as the prime contracting party and shall use all reasonable efforts to obtain the consent of all required parties to the assignment of each such Purchased Right, but Buyer shall be entitled to the benefits of each such Purchased Right accruing from and after the Effective Time to the extent that the Seller is entitled to such benefits and may provide Buyer with such benefits without violating the terms of such Purchased Right; provided that this Section 5.14 shall not be construed as a guarantee by any of the Seller Parties of payment by any third party under any such Purchased Right.

Section 5.15 Cooperation with Financings and Financial Reporting; Additional Financial Statements.

(a) The Seller Parties acknowledge and understand that Buyer or its Affiliates may be required to obtain certain information relating to the Operations, including audited or unaudited financial statements of the Seller, and disclose such information in registration statements and other documents filed with the United States Securities and Exchange Commission under the federal securities laws or in disclosure documents given investors or lenders in certain securities offerings or other financings.

unaudited balance sheet of the Seller as of the end of that fiscal quarter and the related statements of income or operations, cash flows and members’ equity for that fiscal quarter and for the period of the Seller’s fiscal year ended with that quarter, in each case (i) setting forth in comparative form the figures for the corresponding portion of the Seller’s previous fiscal year, (ii) prepared on the same combined, consolidated or other basis on which the Financial Statements were prepared in accordance with GAAP applied on a basis consistent (A) throughout the periods indicated (excepting footnotes) and (B) with the basis on which the Financial Statements were prepared and (iii) certified by the Seller’s chief accounting officer as to compliance with Section 3.12 of this Agreement.

Section 5.16 Damage to Vessels

(a) If, prior to the Closing, any Vessel shall become an actual or constructive total loss, Buyer shall have no obligation to purchase such Vessel and may elect to exclude such Vessel from the Purchased Assets (such that the Vessel becomes an Excluded Asset) and reduce the Purchase Price by the amount for which such Vessel would be insurable, such amount to be mutually determined by the Seller and Buyer. The Seller shall provide notice to Buyer of any such loss no later than 2 days after the occurrence thereof or the Closing Date, if earlier.

(b) If, prior to the Closing, any Vessel or Vessels sustain damage not amounting to an actual or constructive total loss but in excess of $25,000, the Seller may elect to repair or cause to be repaired the damage to any such Vessels at its expense prior to Closing. The Seller shall provide notice to Buyer of any such damage no later than 3 days after the occurrence thereof or 2 days prior to the Closing Date, if earlier. If the Seller elects to repair or cause to be repaired such Vessels at its expense, such notice to Buyer shall include an irrevocable undertaking to such effect. If the Seller does not elect to repair or cause to be repaired such Vessels at its expense in such notice, Buyer may elect (i) to reduce the Purchase Price by the amount necessary to restore any such damaged Vessels to their prior condition or (ii) to exclude such Vessels from the Purchased Assets (such that they become Excluded Assets) and reduce the Purchase Price by the amount for which such Vessels would be insurable, such amount to be mutually determined by the Seller and Buyer.

(c) If Buyer and the Seller are unable to mutually determine the amount of any damage or the cost to restore any such damage under this Section 5.16 within 10 days of Buyer’s receipt of notice thereof, the issues remaining in dispute shall be submitted to a nationally recognized marine appraisal firm selected by the Seller from a list of three such firms provided by Buyer (the “Appraisal Firm”), along with all work papers, schedules and calculations related to the matter in dispute. Within 30 days after such submission, the Appraisal Firm shall issue a letter report determining the amount in dispute, which shall be final and binding. Each party shall bear its own expenses in connection with resolving any such dispute, and the Seller and Buyer will each bear half of the fees and costs of the Appraisal Firm.

(d) This Section 5.16 shall in no way modify or limit Buyer’s rights under Article VII, VIII or IX or other provisions of this Agreement.

Section 5.17 Seller’s Access.

From and after the Closing, the Seller shall waive and require its insurers to waive any right of subrogation or recovery against Buyer and its Affiliates with respect to all such insurance policies. The Seller shall cause the Employer Policies to include “Alternate Employer” and “Borrowed Servant” endorsements in favor of Buyer and its Affiliates and shall cause Buyer and its Affiliates to be named as additional insureds on all other such policies, in each case from and after the Closing. Any other insurance maintained by Buyer or its Affiliates or Cenac Towing, Cenac Offshore or their Affiliates shall be excess and not contributory with any insurance provided for in this paragraph.

INDEMNIFICATION

Section 7.1 Seller Parties’ Indemnity Obligations. Each Seller Party, jointly and severally, agrees to indemnify each Buyer Indemnified Party against, and hold each Buyer Indemnified Party harmless from and against, any and all claims, actions, causes of action, proceedings, arbitrations, losses, damages, liabilities, judgments, fines, amounts, penalties, assessments and expenses (including reasonable attorneys’ fees and costs of investigation and defense) (the “Indemnified Amounts”) that arise from, are based on or relate or otherwise are attributable to (i) any breach of any representation or warranty made by or on behalf of any Seller Party in this Agreement or in any certificate delivered in connection herewith (without giving effect to any supplement to Seller Parties’ disclosure schedules), (ii) any breach or

-28-

nonfulfillment by any Seller Party of or default by any Seller Party under any covenant in this Agreement, (iii) any Lien on any of the Purchased Assets arising from or relating to events occurring or circumstances existing prior to the Closing, (iv) the Excluded Liabilities or (v) without limiting the generality of any of the foregoing, the ownership or operation of the Vessels and the other Purchased Assets by any Seller Party prior to the Closing Date. Notwithstanding the foregoing, the Seller Parties shall not be required to indemnify or hold harmless the Buyer Indemnified Parties on account of any Indemnified Amounts arising under Section 7.1(i) above (other than with respect to breaches of representations and warranties contained in Sections 3.1, 3.2, 3.5, 3.7, 3.13(c), 3.14, 3.21 and 3.24 (the “Identified Representations”), as to which the Deductible Amount shall not apply) unless the aggregate liability of the Seller Parties in respect of all Indemnified Amounts exceeds the Deductible Amount, and then only for the amount by which the Indemnified Amounts exceed the Deductible Amount; provided, however, that in the case of a breach of the representations and warranties contained in Section 3.13(a) as applicable to Vessels, the Seller Parties shall indemnify and hold harmless the Buyer Indemnified Parties for 50% of the amount by which the Indemnified Amounts exceed the Deductible Amount. In no event shall the Seller Parties’ aggregate liability to the Buyer Indemnified Parties under Section 7.1(i) above exceed the Ceiling Amount (other than with respect to breaches of the Identified Representations, as to which the Ceiling Amount shall not apply).

Section 7.2 Buyer’s Indemnity Obligations. Buyer shall indemnify each Seller Indemnified Party against, and hold each Seller Indemnified Party harmless from and against, any and all Indemnified Amounts that arise from, are based on or relate or otherwise are attributable to (i) any breach of any representation or warranty made by or on behalf of Buyer in this Agreement or in any certificate delivered in connection herewith, (ii) any breach or nonfulfillment by Buyer of or default by Buyer under any covenant in this Agreement or (iii) the Assumed Liabilities, in each case except to the extent such Indemnified Amount relates to a matter for which indemnification would be provided under Section 7.1. Notwithstanding the foregoing, Buyer shall not be required to indemnify or hold harmless the Seller Indemnified Parties on account of any Indemnified Amounts arising under Section 7.2(i) above unless the aggregate liability of Buyer in respect of all Indemnified Amounts exceeds the Deductible Amount, and then only for the amount by which the Indemnified Amounts exceed the Deductible Amount. In no event shall the Buyer’s aggregate liability to the Seller Indemnified Parties under Section 7.2(i) above exceed the Ceiling Amount (other than with respect to breaches of representations and warranties contained in Sections 4.1 and 4.2, as to which the Ceiling Amount shall not apply).

Section 7.3 Survival. Subject to the limitations set forth in this Agreement, all the provisions of this Agreement shall survive the Closing indefinitely, notwithstanding any investigation at any time made by or on behalf of any party hereto, provided that the representations and warranties set forth in Articles III and IV and in any certificate delivered in connection herewith with respect to any of those representations and warranties shall terminate and expire on the third anniversary of the date hereof, except (a) the representations and warranties of the Seller Parties in Sections 3.15 and 3.21 shall survive until the expiration of the applicable statutes of limitations (including all periods of extension and tolling), (b) the representations and warranties of the Seller Parties set forth in Sections 3.1, 3.2, 3.7 and 3.13(c) shall survive indefinitely, (c) the representations and warranties of the Seller Parties set forth in the Identified Representations (other than Sections 3.1, 3.2, 3.7, 3.13(c) and 3.21, which are

-29-

provided for above) and Sections 3.6, 3.16 and 3.17 shall expire on the fifth anniversary of the date hereof and (d) the representations and warranties of the Seller Parties in Section 3.13(a) shall expire on the second anniversary of the date hereof. After a representation and warranty has terminated and expired, no indemnification shall or may be sought pursuant to this Article VII on the basis of that representation and warranty, provided that no claim presented in writing for indemnification pursuant to this Article VII on the basis of that representation and warranty prior to its termination and expiration shall be affected in any way by that termination and expiration.

Section 7.4 Indemnification Procedures. All claims for indemnification under this Agreement shall be asserted and resolved as follows:

(a) Promptly after receipt by a Person entitled to indemnity under Section 7.1 or Section 7.2 (an “Indemnified Party”) of notice of the assertion of a claim against an Indemnified Party by a Person that is not a party to this Agreement (a “Third-Party Claim”), such Indemnified Party shall give notice to the Person obligated to indemnify under such Section (an “Indemnifying Party”) of the assertion of such Third-Party Claim, provided that the failure to notify the Indemnifying Party will not relieve the Indemnifying Party of any liability that it may have to any Indemnified Party, except to the extent that the Indemnifying Party demonstrates that the defense of such Third-Party Claim is materially prejudiced by the Indemnified Party’s failure to give such notice.

If an Indemnified Party gives notice to the Indemnifying Party pursuant to the preceding paragraph of the assertion of a Third-Party Claim, the Indemnifying Party shall be entitled to participate in the defense of such Third-Party Claim and, to the extent that it wishes (unless (i) the Indemnifying Party is also a Person against whom the Third-Party Claim is made and the Indemnified Party determines in good faith that joint representation would be inappropriate or (ii) the Indemnifying Party fails to provide reasonable assurance to the Indemnified Party of its financial capacity to defend such Third-Party Claim and provide indemnification with respect to such Third-Party Claim), to assume the defense of such Third- Party Claim with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such Third-Party Claim, the Indemnifying Party shall not, so long as it diligently conducts such defense, be liable to the Indemnified Party under this Article VII for any fees of other counsel or any other expenses with respect to the defense of such Third-Party Claim, in each case subsequently incurred by the Indemnified Party in connection with the defense of such Third-Party Claim, other than reasonable costs of investigation. If the Indemnifying Party assumes the defense of a Third-Party Claim, (i) such assumption will conclusively establish for purposes of this Agreement that the claims made in that Third-Party Claim are within the scope of and subject to indemnification, and (ii) no compromise or settlement of such Third-Party Claims may be effected by the Indemnifying Party without the Indemnified Party’s consent unless (A) there is no finding or admission of any violation of Law or any violation of the rights of any Person; (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party; and (C) the Indemnified Party shall have no liability with respect to any compromise or settlement of such Third-Party Claims effected without its consent. If notice is given to an Indemnifying Party of the assertion of any Third-Party Claim and the Indemnifying Party does not, within ten days after the Indemnified Party’s notice is given, give notice to the Indemnified Party of its election

-30-

to assume the defense of such Third-Party Claim, the Indemnifying Party will be bound by any determination made in such Third-Party Claim or any compromise or settlement effected by the Indemnified Party.

Notwithstanding the foregoing, if an Indemnified Party determines in good faith that there is a reasonable probability that a Third-Party Claim may adversely affect it or its Affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the Indemnified Party may, by notice to the Indemnifying Party, assume the exclusive right to defend, compromise or settle such Third-Party Claim, but the Indemnifying Party will not be bound by any determination of any Third-Party Claim so defended for the purposes of this Agreement or any compromise or settlement effected without its consent (which may not be unreasonably withheld).

Notwithstanding the provisions of Section 10.13, each Seller Party hereby consents to the nonexclusive jurisdiction of any court in which a proceeding in respect of a Third-Party Claim is brought against any Buyer Indemnified Party for purposes of any claim that a Buyer Indemnified Party may have under this Agreement with respect to such proceeding or the matters alleged therein and agrees that process may be served on each Seller Party with respect to such a claim.

With respect to any Third-Party Claim subject to indemnification under this Article VII: (i) both the Indemnified Party and the Indemnifying Party, as the case may be, shall keep the other Person fully informed of the status of such Third-Party Claim and any related proceedings at all stages thereof where such Person is not represented by its own counsel, and (ii) the parties agree (each at its own expense) to render to each other such assistance as they may reasonably require of each other and to cooperate in good faith with each other in order to ensure the proper and adequate defense of any Third-Party Claim.

(b) If any Indemnified Party should have a claim against any Indemnifying Party hereunder that does not involve a Third Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a written notice (the “Indemnity Notice”) describing in reasonable detail the nature of the claim, an estimate of the amount of damages attributable to such claim to the extent feasible (which estimate shall not be conclusive of the final amount of such claim) and the basis of the Indemnified Party’s request for indemnification under this Agreement. If the Indemnifying Party does not notify the Indemnified Party within fifteen days from its receipt of the Indemnity Notice that the Indemnifying Party disputes such claim, the claim specified by the Indemnified Party in the Indemnity Notice shall be deemed a liability of the Indemnifying Party hereunder and shall be paid promptly.

Section 7.5 General. The indemnification provisions in this Article VII shall be enforceable regardless of whether the liability is based upon past, present or future claims or Laws (including any past, present or future bulk sales law, Environmental Law, fraudulent transfer act, occupational safety and health law or product liability, securities or other Law) and regardless of whether any Person (including the Person from whom indemnification is sought) alleges or proves the sole, concurrent, contributory or comparative negligence of the Person seeking indemnification or the sole or concurrent

-31-

strict liability imposed upon the Person seeking indemnification. The rights of the parties to indemnification under this Article VII shall not be limited due to any investigations heretofore or hereafter made by such parties or their representatives, regardless of negligence in the conduct of any such investigations. All representations, warranties, covenants and agreements made by the parties shall not be deemed merged into any instruments or agreements delivered in connection with the Closing or otherwise in connection with the transactions contemplated hereby. The remedies provided in this Agreement shall not be exclusive of any other rights or remedies available to any party either at law or in equity.

ARTICLE VIII

(a) Each Seller Party acknowledges that it has or may have had in the past, currently has and in the future may have access, including in connection with the performance of the Transaction Documents, to Confidential Information (as defined below) relating to the Operations and Buyer and its Affiliates. Each Seller Party agrees that it shall keep, and shall cause its Representatives to keep, confidential all such Confidential Information and, except with the specific prior written consent of Buyer, shall not disclose, and shall cause its Representatives not to disclose, such Confidential Information to any person except (i) the directors, managers, officers, employees, Affiliates, accountants (including independent certified public accountants), advisors, attorneys, consultants or other agents (collectively, “Representatives”) of Buyer and (ii) its own Representatives, provided that those Representatives agree to the confidentiality provisions of this Section 10.1; provided, however, that Confidential Information shall not include such information as (A) becomes known to the public generally through no fault of any Seller Party or its Representatives or (B) is required to be disclosed by law or the order of any Governmental Body under color of law, provided, that prior to disclosing any information pursuant to this clause (B), the Seller Parties shall give prior written notice thereof to Buyer and provide Buyer with the opportunity to contest that disclosure. “Confidential Information” means, with respect to any Person, all trade secrets, know how and other confidential, nonpublic or proprietary information of that Person, including any such information derived from reports, investigations, research, studies, work in progress, codes, marketing, sales or service programs, customer lists, records relating to past service provided to customers, capital expenditure projects, cost summaries, equipment or production system designs or drawings, pricing formulae, contract analyses, financial information, projections, present and future business plans, agreements with vendors, joint venture agreements, confidential filings with any Governmental Body and all other confidential, nonpublic concepts, methods, techniques or processes of doing business, ideas, materials or information prepared or performed for, by or on behalf of that Person.

(b) Because of (i) the difficulty of measuring economic losses as a result of the breach of the covenants in Section 10.1(a) and (ii) the immediate and irreparable damage that would be caused to Buyer or its Affiliates for which it would have no other adequate remedy, in the event of a breach or threatened breach by any Seller Party or its Representatives of the provisions of Section 10.1(a) with respect to any Confidential Information, Buyer shall be entitled to an injunction restraining such Seller Party or its Representatives from disclosing, in whole or in part, that Confidential Information. Nothing herein shall be construed as prohibiting

-37-

(a) If a dispute, controversy or claim arises between the parties relating to the interpretation or performance of this Agreement or the grounds for the termination hereof (“Dispute”), appropriate senior executives of each party who shall have the authority to resolve the matter shall meet to attempt in good faith to negotiate a resolution of the Dispute prior to pursuing other available remedies.

If the senior executives are unable to resolve the Dispute within 30 days from the Dispute Resolution Commencement Date, and any of the parties wishes to pursue such Dispute, then the Dispute shall be mediated by a mutually acceptable mediator within 30 days after written notice by one party to the other demanding non- binding mediation. No party may unreasonably withhold consent to the selection of a mediator. The mediation shall be held in Houston, Texas or at such other place as the parties may mutually agree. Buyer, on one hand, and the Seller Parties, on the other hand, shall share the costs of the mediation equally, except that each party shall bear its own costs and expenses, including attorneys’ fees, witness fees, travel expenses, and preparation costs.

(b) A party may seek relief from a court of competent jurisdiction with respect to a Dispute if the parties are unable to resolve such Dispute pursuant to the provisions of Section 10.2(a) above, provided that any Dispute regarding any obligation of confidentiality or any other claim where interim relief from a court of competent jurisdiction is sought to prevent serious and irreparable injury to one of the parties or to others is not required to be negotiated or mediated prior to seeking relief from such a court, and provided further that Disputes arising out of or in connection with Section 5.6 are not subject to this Section 10.2 and shall be resolved pursuant to the provisions of Section 5.6.

Section 10.3 Seller Parties to Enforce Certain Agreements.

Section 10.6 Waivers and Consents. All waivers and consents given hereunder shall be in writing.
