The date on which the Closing is held is referred to in this Agreement as the “Closing Date.”

Section 1.5 Purchase Price Adjustments.

(a) The Purchase Price shall be adjusted:

(i) downward by the amount of any loss or damage provided for in Section 5.18;

(ii) downward by the amount of property Taxes and other Taxes and charges allocated to Sellers in Section 5.13;

(iii) upward by the amount of documented, ordinary course costs or expenses incurred and paid by Sellers to non-Affiliated parties prior to the Effective Time (and without violation of this Agreement) in respect of ownership or operation of the Purchased Assets after the Effective Time;

(iv) downward by the amount of documented payments, proceeds or other income received by Sellers prior to the Effective Time in respect of ownership or operation of the Purchased Assets after the Effective Time; and

(v) upward by the cost of 50% of the aggregate fuel and lube oil capacity of the Vessels on the Closing Date, based on the capacities set forth on Schedule 1.5(a)(v) and a price to be determined by the Seller Parties and Buyer prior to the Closing Date.

-5-

Sellers object to the Final Adjustment Schedule and the parties fail to resolve such objection within 30 days of Buyer’s receipt of Sellers’ objection notice, the issues remaining in dispute shall be submitted to a nationally recognized accounting firm selected by the Sellers from a list of three such firms provided by Buyer (the “Accounting Firm”), along with all work papers, schedules and calculations related to the matter in dispute. Within 30 days after such submission, the Accounting Firm shall issue a letter report determining the amount in dispute, which shall be conclusive for purposes of this Section 1.5. Buyer shall pay to Sellers, or Sellers shall pay to Buyer, as the case may be, the adjustment amount shown on the conclusive Final Adjustment Schedule, in either case not later than 3 days after such schedule becomes conclusive. Each party shall bear its own expenses in connection with resolving any such dispute, and Sellers and Buyer will each bear half of the fees and costs of the Accounting Firm.

(e) The parties agree and acknowledge that the provisions of this Section 1.5 shall not affect in any way the transfer, exclusion, assumption or allocation of any assets, rights, liabilities or obligations otherwise provided for in this Agreement or indemnification related thereto.

Section 1.6 Closing Limited Partner Units.

(a) As more fully described in Sections 3.25 and 5.16, neither the Partnership nor Buyer shall be obligated to take any steps to register or otherwise qualify the Closing Limited Partner Units under any federal or state securities laws and consequently there are transfer restrictions on such Closing Limited Partner Units.

(b) In the event that the Limited Partner Units are changed or converted into another security in connection with any merger, reclassification or similar transaction, which other security is publicly traded, at any time prior to the Closing, then Buyer shall substitute said security for Limited Partner Units. In any event, in the event of any transaction in which the Limited Partner Units are converted into the right to receive cash, securities or other property, Buyer may, at its option, tender cash in lieu of the Closing Limited Partner Units required hereunder. The aggregate amount of cash so payable in lieu of the Closing Limited Partner Units shall be $181,709,159.77.

(c) During the 30-day period immediately following the First Permitted Transfer Date (the “Window Period”), prior to selling or otherwise disposing of any Closing Limited Partner Units, the Seller Parties (or Permitted Transferees) shall provide the Partnership advance written notice of any such proposed disposition setting forth the number of Closing Limited Partner Units proposed to be disposed of (the “Subject Units”). The Partnership shall have the right (but not the obligation), exercisable for five days after receipt of the notice (“Option Period”), to acquire the Subject Units from the Seller Parties (or Permitted Transferees) at the greater of (i) the Market Value thereof and (ii) the average closing price of the Limited Partner Units on the New York Stock Exchange for the five-day trading period ending on the date the Partnership received the notice (the “Average Trading Price”). If the Partnership does not exercise such right and the Seller Parties (or Permitted Transferees) sell the Subject Units during the Window Period (the “Sold Units”) in a Brokers’ Transaction at an aggregate execution price (without giving effect to brokerage commissions or other fees) (the “Sale Price”) that is less than the Market Value of the Sold Units, then the Partnership shall pay to the Seller

-6-

Parties (or Permitted Transferees), within ten (10) days following the expiration of the Window Period, an amount in cash equal to the Market Value of the Sold Units minus the Sale Price of the Sold Units. If the Seller Parties (or Permitted Transferees) provide proper notice of a proposed sale of Closing Limited Partner Units to occur during the Window Period and such proposed sale is not capable of being effected in accordance with the provisions of Rule 144 as a result of the Partnership’s failure to file timely Exchange Act reports, the Partnership shall be obligated to purchase the Subject Units for the greater of the Market Value thereof and the Average Trading Price.

(d) From the date hereof until the tenth anniversary of the Closing, other than during the Window Period, which shall be governed by paragraph (c) above, prior to selling or otherwise disposing of any Closing Limited Partner Units, the Seller Parties (or Permitted Transferees) shall provide the Partnership advance written notice of any such proposed disposition setting forth the Subject Units and the price offered therefor (the “Offer Price”). The Partnership shall have the right (but not the obligation), exercisable until the close of business on the trading day immediately following receipt of such notice to acquire the Subject Units from the Seller Parties (or Permitted Transferees) at the lower of the Offer Price and the closing price of the Limited Partner Units on the New York Stock Exchange on such trading day.

(e) The Seller Parties (or Permitted Transferees) shall be required to provide the Partnership with a new notice and repeat the procedures required by paragraphs (c) or (d) above, as the case may be, with respect to any Subject Units (for which the Partnership did not exercise its right to purchase) not sold within 60 days after delivery of the notice relating thereto. Settlement of any purchases by the Partnership of Closing Limited Partner Units pursuant to paragraph (c) or (d) above shall occur on a T+5 basis or other basis mutually agreed by the Partnership and the Seller Party (or Permitted Transferee) selling such units.

Section 1.7 Purchase Price Allocation. The Purchase Price, and the cash, Closing Limited Partner Units and assumption of Assumed Liabilities that comprise the Purchase Price, shall be allocated among Cenac Towing, Cenac Offshore and the Stockholder as set forth in Schedule 1.7.

ARTICLE II

Section 2.1 Obligations Assumed. As part of the consideration for the Purchased Assets, and subject to Section 2.2, Buyer shall assume only the following (collectively, the “Assumed Liabilities”):

(a) the indebtedness of the Sellers set forth on Schedule 2.1(a);

(b) each Seller’s obligations that accrue after the Closing under Contracts and Assumed Equipment Leases listed on Schedules 1.1(d)(i) and 1.1(d)(ii) and the IT Contracts listed on Schedule 1.1(f), in each case if and only if they are assigned or transferred to Buyer; and

Buyer expressly disclaims the assumption of any other debt, liability or obligation of any type whatsoever of any Seller Party or in connection with any Seller Party’s assets or business operations, including the following:

(e) any employment, employee benefit or personnel-related liabilities whatsoever of any Seller or ERISA Affiliate, including any liability with regard to the Sellers’ Plans;

Section 5.6 Covenant Against Competition.

(a) As an essential consideration for the obligations of Buyer under this Agreement, each Seller Party hereby agrees and covenants that:

(i) for a period of two years following the Closing Date within the Restricted Territory, each Seller Party shall not, directly or indirectly, whether as principal, agent, employee, shareholder or other equity holder (other than a holding of shares listed on a United States stock exchange or automated quotation system that does not exceed five percent of the outstanding shares so listed), owner, investor, partner or otherwise, individually or in association with any other Person: (A) carry on or engage in any manner in the Restricted Business, (B) solicit customers of the Restricted Business, (C) become the employee of, or otherwise render services on behalf of, any Person that carries on or engages in a business similar to the Restricted Business or (D) induce or attempt to induce any customer, supplier, licensee or business relation of Buyer or any of its Affiliates to cease doing business with Buyer or any of its Affiliates, or in any way interfere with the relationship between any customer, supplier, licensee or business relation of Buyer or any of its Affiliates with Buyer or any of its Affiliates, provided that this Section 5.6(a)(i) shall not prohibit Stockholder’s equity ownership in Horizon Maritime for so long as the Asphalt Business Limitation is satisfied; and

-26-

(ii) for a period of four years following the Closing Date, each Seller Party shall not, directly or indirectly, either for himself or any other Person, (A) solicit or induce or attempt to solicit or induce any employee of or independent contractor providing services to Buyer or any of its Affiliates to leave the employ of or to cease providing services to Buyer or any of its Affiliates, (B) in any way interfere with the relationship between Buyer or any of its Affiliates and any employee of or independent contractor providing services to Buyer or any of its Affiliates or (C) employ, or otherwise engage as an employee, independent contractor or otherwise, any employee of Buyer or any of its Affiliates or any independent contractor of Buyer of any of its Affiliates who had been an employee of any Seller Party or its Affiliates.

(b) Any dispute, controversy or claim arising out of or in connection with this Section 5.6, including the alleged breach of this Section 5.6 or a challenge to its validity or enforceability, shall be settled exclusively by final and binding arbitration in Tarrant County, Texas, administered by the American Arbitration Association (“AAA”) in accordance with the Commercial Arbitration Rules of the AAA; provided, however, that nothing herein is or shall be deemed to preclude Buyer’s resort to the interim relief prescribed in Section 5.6(c), below. 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. Seller Parties acknowledge that Buyer will suffer irreparable damage or injury 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

-27-

Sellers 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 any Seller Parties from rendering services to Buyer in accordance with the Transitional Operating Agreement.

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 except for Permitted 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.

Section 5.9 Consents. 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

-28-

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 (a) the Seller Parties nor (b) Buyer or the Partnership shall, without the prior approval (which may not be unreasonably withheld, delayed or conditioned) of Buyer or the Stockholder, as the case may be, issue, or permit any of their partners, stockholders, 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 and 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. As to the federal income tax (and related state income tax) matters identified in this Section 5.11, including the manner in which the transactions contemplated by this Agreement will be reported by the Seller Parties and the Buyer for income tax purposes (on Tax Returns or otherwise), the Seller Parties and Buyer agree as follows:

(a) The transactions pursuant to this Agreement shall be reported as (x) purchases and sales of assets for federal income tax purposes to the extent attributable to the cash portion of the Purchase Price and any allocable liabilities and adjustments (the “Taxable Sales”) and (y) as contributions of assets in exchange for partnership interests governed by Section 721 of the Code to the extent attributable to the portion of the Purchase Price paid in Limited Partner Units and any allocable adjustments (the “Contributions”). The Buyer or the Partnership shall, in consultation with the Seller Parties, determine how the parties shall report (i) which portions of the Purchased Assets are allocable to the Taxable Sales and which are allocable to the Contributions, (ii) how each Seller Party’s tax bases in the Purchased Assets is allocated among the transactions contemplated by this Agreement, (iii) which liabilities and adjustments are allocable to the Taxable Sales, (iv) the allocation of the cash, liabilities and adjustments allocable to the Taxable Sales among the Purchased Assets and the covenant not to compete contained in Section 5.6 and (v) the tax consequences of the liabilities that are not allocable to the Taxable Sales. All such determinations shall be made in a manner consistent with Schedule 1.7 and shall be binding on the parties. The Seller Parties shall provide the Buyer such information and assistance as it reasonably requests in making such determinations. Each party agrees not to assert, in connection with any Tax Return, tax audit or similar proceeding, any position inconsistent with the allocations and determinations described in this Section 5.11(a).

(b) Within 180 days after the Closing Date, the Seller Parties and Buyer shall jointly prepare IRS Forms 8594 to report the allocations of the Purchase Price attributable to the Taxable Sales in a manner consistent with Section 5.11(a).

-29-

(c) Differences between the fair market value and the tax basis of the Purchased Assets allocable to the Contributions shall be taken into account in the manner required by Section 704(c) of the Code. The Partnership will elect the remedial allocation method of Treas. Reg. § 1.704-3(d) as to all such assets. All other determinations regarding the application of Section 704(c), the determination and maintenance of capital accounts and other tax matters relating to the Contributions and the assets allocable thereto shall be made in the discretion of the Partnership in a manner consistent with the Partnership Agreement. The Seller Parties will be bound by the terms of the Partnership Agreement; among other things, Buyer may, but is not required to, make special allocations to one or more Seller Parties under the Partnership Agreement to cause Limited Partner Units held by any Seller Party to have the same economic characteristics as other outstanding Limited Partner Units.

Section 5.12 Taxes Upon Conveyance and Transfer. The Sellers 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 Sellers, Buyer shall reimburse the Sellers for 100% of any such Taxes remitted by the Sellers (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 Sellers for which Buyer has reimbursed the Sellers, and the Sellers 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. Sellers agree 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. Sellers shall be responsible for any Taxes arising out of or relating to the use and operation of the Purchased Assets, the operations of any 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 Sellers 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 ▇▇▇▇, Buyer or Sellers, 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 Sellers 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, Sellers are

-30-

not assigning to Buyer any Contract, Assumed Equipment Lease or IT 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, Assumed Equipment Lease or IT Contract or right (collectively, “Purchased Rights”), after the Closing, Sellers 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 after the Closing to the extent that Sellers are 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 Sellers, and disclose such information in registration statements and other documents filed with the Commission under the federal securities laws or in disclosure documents given investors or lenders in certain securities offerings or other financings. The Seller Parties agree promptly to prepare and provide to Buyer any such information and to cooperate fully and promptly, and shall cause their Affiliates, accountants, counsel and other agents and representatives to cooperate fully and promptly, with Buyer in connection therewith.

(b) The Seller Parties will furnish to Buyer as soon as available and in any event within 20 days after the end of each of the Sellers’ fiscal quarters which ends prior to the Closing Date, an unaudited balance sheet of the Sellers as of the end of that fiscal quarter and the related statements of income or operations and stockholders’ or other owners’ equity for that fiscal quarter and for the period of the Sellers’ fiscal year ended with that quarter, in each case (i) setting forth in comparative form the figures for the corresponding portion of the Sellers’ 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 Sellers’ chief accounting officer as to compliance with Section 3.12 of this Agreement.

Section 5.16 Restrictions on Transfer; Legends.

(a) The Closing Limited Partner Units may not be transferred (whether by sale, assignment, pledge or otherwise) by the Seller Parties or any Permitted Transferee (i) unless such transfer is registered under the Securities Act or is made pursuant to the exemption from registration under Section 4(1) of the Securities Act or Rule 144 under the Securities Act, (ii) without affording the Partnership the Right of First Refusal and (iii)(A) in a non-Brokers’ Transaction, to any Person that is not a citizen of the United States within the meaning of Section 50501 of Title 46 of the United States Code for the purpose of operating vessels in the coastwise trade of the United States (a “Non-Citizen”) or (B) in a Brokers’ Transaction, knowingly to a Non-Citizen.

-31-

(b) Notwithstanding anything in this Agreement to the contrary, the Stockholder may give as a gift or bequeath Closing Limited Partner Units to any relative of the Stockholder or donate such Closing Limited Partner Units to any trust established by the Stockholder for estate planning purposes, at any time without compliance with the Right of First Refusal or the provisions of Section 5.16(c), such transferee in each case to be hereinafter referred to as a “Permitted Transferee;” provided that (i) the Permitted Transferee in each case agrees in writing to take such Closing Limited Partner Units subject to the transfer restrictions set forth in Section 5.16(a), (ii) such transfer is effected in a transaction registered under the Securities Act or in compliance with an exemption thereunder and (iii) such transfer does not call into question the exemption from registration under which the Closing Limited Partner Units were initially issued by the Partnership to Cenac Towing and the Stockholder.

(c) Except as permitted by Section 5.16(b), prior to any proposed transfer (whether by sale, assignment, pledge or otherwise) of the Closing Limited Partner Units by a Seller Party or a Permitted Transferee, the proposed transferor (the “Transferor”) will give written notice to the Partnership of its intention to effect such transfer. Each such notice shall describe the manner and circumstances of the proposed transfer in sufficient detail, contain evidence of citizenship of the proposed transferee (for a non-Brokers’ Transaction) and shall be accompanied by a written opinion of legal counsel who shall be reasonably satisfactory to the Partnership, addressed to the Partnership, to the effect that (i) the proposed transfer of the securities in question may be effected without registration under the Securities Act, (ii) such proposed transfer does not call into question the exemption from registration under which such Closing Limited Partner Units were initially issued by the Partnership to any Seller Party and (iii) if a non-Brokers’ Transaction, the proposed transferee is a citizen of the United States within the meaning of Section 50501 of Title 46 of the United States Code for the purpose of operating vessels in the coastwise trade of the United States. Any such legal opinion must be reasonably satisfactory to the Partnership and must state that it may also be relied upon by any applicable transfer agent or stock exchange or counsel to the Partnership. The Partnership may also require a certificate of the Transferor that certifies as to matters that assist the Partnership in establishing compliance with securities laws as at the time of the proposed transfer (including representations relating to the proposed transfer and the transferee of the type set forth in Section 3.25 hereto).

(d) Upon compliance with the terms hereof to the reasonable satisfaction of the Partnership, the Transferor shall be entitled to transfer such Limited Partner Units in accordance with the terms of the notice delivered by the Transferor to the Partnership.

(e) The Partnership may issue stop transfer instructions to any transfer agent for the Limited Partner Units in order to implement any restriction on transfer described in this Section 5.16. The Closing Limited Partner Units shall contain the following legend:

SUCH UNITS MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE PARTNERSHIP AS TO THE AVAILABILITY OF AN EXEMPTION FROM REGISTRATION.

-32-

THE UNITS WERE ISSUED PURSUANT TO AN AGREEMENT WHICH INCLUDES ADDITIONAL RESTRICTIONS ON TRANSFER AND COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD HEREOF TO THE SECRETARY OF THE PARTNERSHIP AT THE PRINCIPAL EXECUTIVE OFFICES OF THE PARTNERSHIP.

Upon the request of any holder of Closing Limited Partner Units and receipt of opinions or other documents reasonably satisfactory to the Partnership and its transfer agent, the Partnership shall authorize and direct its transfer agent to remove the second paragraph of the foregoing legend, from the certificates representing (or other evidence of) such Closing Limited Partner Units on or after the expiration of such restrictions in accordance with the provisions of this Section 5.16.

(f) The Partnership shall have no obligation to effect any transfer on its books and records (and no such attempted transfer shall be effective) unless such transfer is made in accordance with the terms of this Section 5.16 and, to the extent applicable, Section 1.6.

Section 5.18 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 Excluded Assets) and reduce the Purchase Price by the amount for which such Vessel would be insurable, such amount to be mutually determined by the Sellers and Buyer. Sellers 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 Sellers may elect to repair or cause to be repaired the damage to any such Vessels at their expense prior to Closing. Sellers 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 Sellers elect to repair or cause to be repaired such Vessels at their expense, such notice to Buyer shall include an irrevocable undertaking to such effect. If Sellers do not elect to repair or cause to be repaired such Vessels at their 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 Sellers and Buyer.

(c) If Buyer and Sellers are unable to mutually determine the amount of any damage or the cost to restore any such damage under this Section 5.18 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 Sellers 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 Sellers and Buyer will each bear half of the fees and costs of the Appraisal Firm.

(d) This Section 5.18 shall in no way modify or limit Buyer’s rights under Articles VII, VIII or IX or other provisions of this Agreement.

ARTICLE VII
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 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, other than Permitted Liens, 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, 3.24 and 3.25 (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).

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, 4.2 and 4.6, as to which the Ceiling Amount shall not apply).

-35-

Section 7.3 S Corporation Built-In Gain Indemnity. If, after the Closing, Buyer or any of its Affiliates sell or otherwise dispose of any Towing Asset in a transaction in which gain or loss is recognized for federal income tax purposes, Buyer will pay to Cenac Towing the Built-In Gain Indemnity Amount with respect to the calendar year in which such sale or disposition occurs on or before March 1 of the following year; provided that no such indemnity obligation will arise with respect to (a) any such sale or disposition that occurs after June 30, 2018, (b) any such sale or disposition that occurs at a time when Cenac Towing is not an S corporation within the meaning of Section 1361 of the Code or (c) gain or loss recognized with respect to the Taxable Sales. The reasonable determinations made by Buyer and its Affiliates of the amounts of the Asset Gain Amount, Built-In Gain Indemnity Amount, Recognized Built-In Gain Amount and Recognized Built-In Gain Limitation will be binding on the Seller Parties. A sample calculation is set forth on Exhibit F hereto.

Section 7.4 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, 3.21 and 3.25 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), 3.21 and 3.25, which are 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 7.5 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, Section 7.2, or Section 7.3 (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

-36-

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 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

-37-

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 7.6 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 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.

(c) by the Seller Parties if any of the conditions set forth in Section 8.2 hereof shall have become incapable of fulfillment by the Outside Date and shall not have been waived by the Seller Parties;

-42-

(d) by Buyer or the Seller Parties by written notice thereof to the other party if the transactions contemplated hereby shall not have been consummated on or before the Outside Date or such other date, if any, as Buyer and the Seller Parties shall agree upon in writing; or

(e) by Buyer or the Seller Parties if the consummation of the transactions contemplated hereby would violate any nonappealable final order, decree or judgment of any Governmental Body or court having competent jurisdiction prohibiting consummation of the transactions contemplated by this Agreement;

provided, however, that neither Buyer nor Seller Parties shall be allowed to exercise any right of termination pursuant to (i) Section 9.1(b) or (c) if Buyer or the Partnership (if Buyer is seeking to terminate) or any Seller Party (if the Seller Parties are seeking to terminate) is then in material breach or has materially failed to perform any of its representations, warranties or covenants in this Agreement or (ii) Section 9.1(d) or (e) if a material breach or failure to perform the representations, warranties or covenants in this Agreement by Buyer or the Partnership (if Buyer is seeking to terminate) or any Seller Party (if the Seller Parties are seeking to terminate) proximately caused the Closing not to have been consummated on or before the Outside Date or the issuance of such order, decree or judgment, as the case may be.

(a) Each party’s right of termination pursuant to Section 9.1 hereof is in addition to any other rights it may have under this Agreement or otherwise, and the exercise of such right of termination will not be an election of remedies.

ARTICLE X
GENERAL PROVISIONS

Section 10.1 Confidentiality.

(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

-43-

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 or the Partnership 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 or the Partnership 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 Buyer or the Partnership from pursuing any other available remedy for such breach or threatened breach, including the recovery of damages.

Section 10.2 Dispute Resolution.

(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. The initial meeting between the appropriate senior executives, which shall be held within 10 business days of notice to the other party of the Dispute in Houston, Texas or such other place as the parties may mutually agree, shall be referred to herein as the “Dispute Resolution Commencement Date.” Discussions and correspondence relating to attempted resolution of such Dispute shall be treated as confidential information developed for the purpose of settlement and shall be exempt from discovery or production and shall not be admissible. 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

-44-

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.

(b) The Operators shall have day-to-day control over the operation and maintenance of the Purchased Operations, subject to the limitations and requirements of this Agreement.

(ii) enter into, amend or waive any term of any contract or agreement to which an Operator is a party or to which any of the Purchased Operations may be subject and to which any other Operator or any of its Affiliates or any family member of the Stockholder is also a party;

(e) Notwithstanding any other provision of this Agreement, in the event that an Operator becomes aware of an emergency, including a release of materials requiring reporting to a Governmental Body or requiring an immediate response in order to comply with applicable Laws or to protect human health or the environment, affecting the Purchased Operations or any of the Owner’s assets, properties or business associated therewith, the Operators shall first, in compliance with the Comprehensive Environmental Response, Compensation and Liability Act and other applicable Laws, provide any legally required notice to Governmental Bodies, including notice to the National Response Center of any reportable release from a vessel as soon as any person in charge of such vessel has knowledge of such release. The Operators shall perform all release response obligations required by Law, including compliance with the U.S. Coast Guard tank vessel response plan regulations for oil, 33 C.F.R. §§ 155.1050 and 155.1052, regarding equipment and response resource requirements (containment booms, oil recovery devices and storage capacity for recovery), within the response timeframes

required by Law and to protect human health or the environment. As soon as reasonably possible, but in no event more than six (6) hours after the start of the emergency, the Operators shall notify the Owner of the emergency and all information related to the emergency, including any emergency response actions. Thereafter, the Operators shall provide periodic updates of information related to the emergency and all emergency response actions, on at least a daily basis. As soon as reasonably possible after receipt of the Operator’s Notice related to the emergency and from time to time thereafter, the Owner shall instruct the Operators as to any additional actions that the Owner desires the Operators to take in order to address the emergency. Within five (5) days of the start of the emergency, the Operators shall provide the Owner with a cost estimate of emergency response actions, and shall thereafter update monthly cost estimates to reflect any actual or expected emergency expenditures. Within five (5) days after receipt of such cost estimate, the Owner shall acknowledge receipt of such cost estimate from the Operators and, in such acknowledgement, shall approve or disapprove such cost estimate update. The Owner’s acknowledgement shall be effective when transmitted to the Operators in writing in the manner specified in Section 10.4. Until the Owner’s acknowledgement becomes effective, the Operators may incur any expenditure or take any other actions reasonably necessary under the circumstances to comply with Law or safeguard lives or property in connection with the response to emergencies affecting the Purchased Operations or the associated assets, properties or business of the Owner, the cost of which will be borne by the Owner.

(f) The Operators shall meet with the Owner from time to time, at the Owner’s reasonable request, in order to review the operation and maintenance of the Purchased Operations.

2.2 Personnel.

(a) The Stockholder agrees to make himself available to provide personal services to the Owner as reasonably requested from time to time. In addition, each of the Cenac Companies shall employ, retain and have supervision over such Service Providers as such Cenac Company deems reasonably necessary and appropriate for its performance of Services in accordance with the standards set forth in Section 2.1(b). All such Service Providers shall have received such training as is required by applicable Laws. The Cenac Companies shall pay all expenses incurred in connection with the retention of any Service Providers to perform the Services, including compensation, consulting or other service fees, salaries, wages and overhead and administrative expenses charged to or incurred by the Cenac Companies and, if applicable, social security taxes, workers’ compensation insurance, retirement and insurance benefits, incentives, bonuses and other similar expenses. The Cenac Companies shall comply with all Laws relating to the employment or retention of Service Providers, including Laws relating to withholding of Taxes, employment discrimination, fair labor standards and the Cenac Company Plans. Each of the Cenac Companies represents and warrants that (i) no Employee is covered by the terms of a collective bargaining agreement with any union organization and (ii) each such Cenac Company has all necessary contractual rights to secure the services of the individuals and entities reasonably necessary to perform the Services.

(b) The Cenac Companies shall provide as soon as reasonably practicable to the Owner a complete list, as of the date hereof, of all Service Providers, listing the individual’s status, title or position held, base salary, any commissions or other compensation

paid or payable, all employee benefits received by such Service Provider and any other terms of any oral or written agreement (including a copy of any such written agreement) with either of the Cenac Companies or any of their respective Affiliates. Such list shall be updated from time to time as requested by the Owner on reasonable Notice. The Owner may direct that either of the Cenac Companies terminate its use of any Service Provider to provide any of the Services by providing the Operators with written Notice.

(c) This Agreement does not and shall not be construed to establish an employment relationship between the Owner (or its Affiliates) and any Service Provider. Unless and until otherwise determined by the Owner, the Employees shall not transfer to or otherwise be employed by the Owner (or its Affiliates), but shall be retained in the employ of the applicable Cenac Company. No Service Provider is a party to this Agreement, nor shall any Operator or such Service Provider be entitled to assert that such Service Provider has become an employee of the Owner or its Affiliates through or in connection with the rendering of Services in accordance with this Agreement.

(d) Notwithstanding the foregoing, the Owner, in its sole discretion, may hire any Person (including any Service Provider) to serve as an employee of the Owner or its Affiliates or, if applicable, an independent contractor of the Owner or its Affiliates. The Operators shall cooperate with the Owner and its Affiliates in providing access to Service Providers, on reasonable Notice, for purposes of interviewing and other pre-application screening as the Owner may reasonably request. Each of the Operators shall not, directly or indirectly, either for itself or any other Person, discourage any Service Provider from agreeing to a direct employment or engagement with the Owner or its Affiliates or otherwise interfere with any efforts by the Owner or its Affiliates to hire or engage any Service Provider directly.

(e) Any notice required under the Federal Workers Adjustment and Retraining Notification Act (“WARN Act”) that is, has been or shall be required of the Cenac Companies to their Employees or former employees by reason of its obligations under the WARN Act resulting from the transactions contemplated by the Purchase Agreement (including this Agreement) or any subsequent mass layoff or plant closing during the term of this Agreement has been or shall be given by the Cenac Companies. The Cenac Companies shall be solely responsible for any severance or other costs associated with the termination of the employment or engagement of any Service Provider.

(f) The Owner and the Operators agree that the Owner is a statutory employer of the Employees solely for purposes of La. Rev. Stat. 23:1061 and not for any other purpose whatsoever. Irrespective of the Owner’s status as a statutory employer or special employer (as defined in La. Rev. Stat. 23:1031(C)) of the Employees, the Cenac Companies shall remain primarily responsible for the payment of Louisiana Workers’ Compensation benefits to the Employees and shall not be entitled to seek contribution for any such payments from the Owner or any of its Affiliates. Further, the Cenac Companies agree to protect, defend, indemnify and hold harmless the Owner Indemnified Parties from any and all claims for compensation benefits by the Employees against any of the Owner Indemnified Parties and hereby waives any right of the Cenac Companies’ insurers to seek reimbursement of any compensation benefits owed or paid.

2.3 Employee benefit plans.

(a) Schedule 2.3 contains a complete list of each Cenac Company Plan.

(b) The Cenac Companies have made available to the Owner a true and correct copy (or, with respect to any unwritten arrangement, an accurate written description) of each Cenac Company Plan and, to the extent applicable, copies of any related trusts, insurance policies, amendments, third-party administration contracts, the most recent summary plan description, summary of material modifications, favorable determination letters, actuarial reports, FAS-106 reports and the three most recently filed Form 5500 annual reports filed with the Internal Revenue Service and the United States Department of Labor.

(c) Each Cenac Company Plan intended to be qualified under Section 401(a) of the Code is and has been so qualified. Each Cenac Company Plan is and has been operated and administered in material compliance with its terms and the provisions of all applicable laws, rules and regulations, including ERISA and the Code. There are no pending actions, suits or claims against any Cenac Company Plan other than routine claims for benefits, qualified domestic relations orders and medical child support orders. The Cenac Companies and each ERISA Affiliate have made any and all required contributions to the Cenac Company Plans and have satisfied any and all taxes or other obligations related to employees of the Cenac Companies and the Cenac Company Plans as of the date of this Agreement and the transactions contemplated by this Agreement will not, either alone or in combination with any other event, result in the Owner having any liability under or related to any Cenac Company Plan. There have been no “prohibited transactions” (as described in Section 406 of ERISA or Section 4975 of the Code) with respect to any of the relevant Cenac Company Plans.

(d) Each Cenac Company Plan or compensation arrangement that is a nonqualified deferred compensation plan subject to Section 409A of the Code has been operated and administered in compliance with Section 409A of the Code from the period beginning January 1, 2005 to the date hereof.

(e) Neither the execution nor the delivery of the Purchase Agreement or this Agreement nor the consummation of the transactions contemplated thereby or hereby will (either alone or in conjunction with any other event): (i) result in any payment (including severance, unemployment compensation, parachute payments or otherwise) becoming due to any employee of either of the Cenac Companies or any ERISA Affiliate; (ii) significantly increase any benefits otherwise payable under any Cenac Company Plan; or (iii) result in any acceleration of the time of payment, funding or vesting of any material benefit to the employees of either of the Cenac Companies or any ERISA Affiliate.

(f) The Cenac Companies have provided for and will provide for the full and complete satisfaction of any and all liabilities of any kind whatsoever that the Cenac Companies may have or may hereafter incur with respect to any Service Provider, including all liabilities under any Cenac Company Plan.

2.4 Property.

The Cenac Companies shall keep a full and complete account of all costs and expenses incurred in connection with the performance of the Services in the manner set forth in the Accounting Procedures. The Owner shall have no responsibility for, and shall not reimburse or pay: (i) any Direct Costs or Overhead Costs related to services performed by a Service Provider for any period prior to the Closing Date, including bonuses paid to Service Providers during the term of this Agreement that relate all or in part to services provided prior to the Closing Date; or (ii) any costs, expenses, liabilities, obligations, expenditures or other amounts incurred or made in violation of this Agreement or for which any Operator is liable or responsible pursuant to this Agreement or the Purchase Agreement.

3.2 Billing and Payment. The Cenac Companies shall submit monthly invoices to the Owner including itemized statements setting forth, in reasonable detail, the Service Fee and the Direct Costs and related Overhead Costs incurred or paid by the Operators in providing the Services for the preceding calendar month. The Cenac Companies shall provide to the Owner, at the Owner’s reasonable request, appropriate documentation supporting the incurrence of Direct Costs and related Overhead Costs, including receipts, time sheets and similar documentation. The Owner agrees to pay the Cenac Companies such Service Fee, Direct Costs and Overhead Costs within ten (10) days of its receipt of each such monthly invoice. The Cenac Companies and the Owner may arrange on mutually acceptable terms for the payment by the Owner of Direct Costs on an “as incurred” basis, and the invoice for any month in which such payments have been made need not include such payments (or, if included, shall reflect

such payments as credits to the Direct Costs otherwise due). In no event shall the Owner directly pay or be deemed to have directly paid any Direct Costs provided for in Section 4(a), 4(b) or 4(d) of Exhibit B, it being agreed and acknowledged that the Owner’s sole responsibility hereunder with respect to any such costs is to reimburse the Cenac Companies for such costs incurred by them, to the extent provided herein.

3.3 Billing Disputes. Should there be a dispute as to the propriety or accuracy of any invoiced amounts, the Owner shall pay all undisputed amounts shown on each invoice, but shall be entitled to withhold payment of any amount in dispute and shall promptly notify the Operators of such disputed amount.

ARTICLE IV
COVENANT AGAINST COMPETITION

4.1 As an essential consideration for the obligations of the Owner under this Agreement, each of the Operators hereby agrees and covenants that, for a period commencing on the date of this Agreement and ending on the second anniversary of the respective dates of the last work performed hereunder:

(a) within the Restricted Territory, each of the Operators shall not, directly or indirectly, whether as principal, agent, employee, shareholder or other equity holder (other than a holding of shares listed on a United States stock exchange or automated quotation system that does not exceed five percent of the outstanding shares so listed), owner, investor, partner or otherwise, individually or in association with any other Person: (A) carry on or engage in any manner in the Restricted Business, (B) solicit customers of the Restricted Business, (C) become the employee of, or otherwise render services on behalf of, any Person that carries on or engages in a business similar to the Restricted Business or (D) induce or attempt to induce any customer, supplier, licensee or business relation of the Owner or any of its Affiliates to cease doing business with the Owner or any of its Affiliates, or in any way interfere with the relationship between any customer, supplier, licensee or business relation of the Owner or any of its Affiliates with the Owner or any of its Affiliates, provided that this Section 4.1(a) shall not prohibit Stockholder’s equity ownership in Horizon Maritime for so long as the Asphalt Business Limitation is satisfied; and

(b) each of the Operators shall not, directly or indirectly, either for himself or any other Person, (A) solicit or induce or attempt to solicit or induce any employee of or independent contractor providing services to the Owner or any of its Affiliates to leave the employ of or to cease providing services to the Owner or any of its Affiliates, (B) in any way interfere with the relationship between the Owner or any of its Affiliates and any employee of or independent contractor providing services to the Owner or any of its Affiliates or (C) employ, or otherwise engage as an employee, independent contractor or otherwise, any employee of the Owner or any of its Affiliates or any independent contractor of Owner or any of its Affiliates who had been an employee of any Operator or its Affiliates.

4.2 Any dispute, controversy or claim arising out of or in connection with this Article IV, including the alleged breach of Section 4.1 or a challenge to its validity or

enforceability, shall be settled exclusively by final and binding arbitration in Tarrant County, Texas, administered by the American Arbitration Association (“AAA”) in accordance with the Commercial Arbitration Rules of the AAA; provided, however, that nothing herein is or shall be deemed to preclude Buyer’s resort to the interim relief prescribed in Section 4.3, below. 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 4.3, below.

4.3 In the event of a breach or threatened breach by any of the Operators of any of the provisions of this Article IV, the Owner 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 Section 4.3) or from a court of competent jurisdiction. The Operators acknowledge that the Owner will suffer irreparable damage or injury 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, the Owner 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 Article IV, (ii) a decree for the specific performance of this Article IV or (iii) the Owner’s reasonable attorneys’ fees, costs and expenses related to such interim relief; provided, however, that the Owner agrees to pay for any Operator’s reasonable attorneys’ fees, costs and expenses related to interim relief sought by the Owner in the event that the Operators prevail and no such interim relief is granted. Such interim relief is in addition to any other rights the Owner may have, including the right to seek damages.

4.4 The Owner and each of the Operators hereby agree that this Article IV is a material and substantial part of the transactions contemplated by this Agreement. Each of the Operators further agrees and acknowledges that the covenants in Section 4.1 are reasonable with respect to their duration, scope and geographical area.

4.5 The covenants in this Article IV are severable and separate, including within provisions, subparts or portions thereof, and the unenforceability of any specific covenant, provision or subpart thereof in this Article IV is not intended by any party hereto to, and shall not, affect the provisions of any other covenant in this Article IV. If any arbitrator or panel of

arbitrators, or any court pursuant to Section 4.3 above, determines that the terms, scope, time or territorial restrictions set forth in Section 4.1 are unreasonable as applied to an Operator, 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 Section 4.3 above) deems reasonable, and thereby shall be reformed to that extent. All the covenants, provisions and subparts thereof in this Article IV 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 of the Operators against the Owner, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Owner of any covenant, provision or subpart in this Article IV. The covenants contained in this Article IV shall not be affected by any breach of any other provision hereof by any party hereto and shall not prevent any Operator from rendering the Services to the Owner in accordance with this Agreement.

ARTICLE V
AUDITS

On not less than thirty (30) days’ advance written Notice to the Operators, the Owner or its authorized representative(s) shall have the right during regular business hours to audit all books and records of the Operators relating to the performance by the Operators of the obligations hereunder. The Operators acknowledge and agree to cooperate with the Owner’s audit of such books and records for any reason relating to any Operator’s performance under this Agreement, including the Owner’s investigation of the accuracy of amounts billed, demanded or paid hereunder for Services and the Operator’s compliance with all Environmental Laws, other applicable Laws, safety policies and practices. All audits shall be completed in a reasonable time frame not to exceed ninety (90) days per audit. The Owner shall have two (2) years after the termination of this Agreement during which to conduct an audit of the Operators’ books and records relating to the performance by the Operators of the obligations hereunder, and any claim arising out of or based in whole or in part on the information produced or obtained by the performance of any such audit must be made, if at all, within such two-year period. The audit rights set forth herein shall survive termination of this Agreement. In addition, the Operators shall promptly provide information from or access to its books and records that the Owner or any of its Affiliates request in connection with the preparation, audit or performance of any procedures with respect to the financial statements of the Owner or its Affiliates and shall cooperate with the Owner in the implementation of internal controls, recordkeeping and other systems, practices or policies required by Law (including the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002) and GAAP with respect to the Purchased Operations.

ARTICLE VI

This Agreement does not create a partnership or joint venture between any of the parties hereto.

(b) Neither this Agreement nor the performance by any of the parties of their respective obligations hereunder shall operate to convey, license or otherwise transfer from one party to another any (i) trade secrets or, (ii) except as expressly provided otherwise, patent, know-how or other intellectual property rights.

ARTICLE VII
INDEMNIFICATION

7.1 Indemnity by the Cenac Companies. Each of the Cenac Companies, jointly and severally, agrees to indemnify each Owner Indemnified Party against, and hold each Owner 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”) asserted by a Third Party or sustained or incurred by such Owner Indemnified Party with respect to a Third Party that arise from, are based on or relate or otherwise are attributable to (i) the gross negligence or willful misconduct of any Operator (or any Service Provider, agent of any Operator or other Person performing obligations of an Operator hereunder) in the performance or nonperformance of the Services or (ii) any alleged violation or violation by any Operator (or any Service Provider, agent of an Operator or other Person performing obligations of an Operator hereunder) of (A) any Laws related to the employment of labor, including Laws relating to withholding of Taxes, employee benefits, employment discrimination, harassment and retaliation or wages, hours or other fair labor standards or (B) the terms of the Cenac Company Plans; provided that the Cenac Companies shall not be obligated to indemnify the Owner Indemnified Parties to the extent that such Indemnified Amounts relate to a breach by Owner of this Agreement.

7.2 Indemnity by the Owner. The Owner shall indemnify each Operator Indemnified Party against, and hold each Operator Indemnified Party harmless from and against, any and all Indemnified Amounts asserted by a Third Party or sustained or incurred by such Operator Indemnified Party with respect to a Third Party that arise from, are based on or relate or otherwise are attributable to the performance or nonperformance of the Services, in each case except to the extent such Indemnified Amount relates to (i) a matter for which indemnification would be provided under Section 7.1 or (ii) a breach by any Operator of this Agreement.

7.3 General Provisions.

(a) All claims for indemnification hereunder shall be asserted and resolved subject to and in accordance with the provisions of Section 7.5 of the Purchase Agreement.

(b) In no event shall the Owner or any Operator be liable under this Article VII or otherwise in respect of this Agreement for exemplary, special, punitive, indirect, remote, speculative or consequential damages except to the extent an Owner Indemnified Party (in the case of liabilities of an Operator hereunder) or an Operator Indemnified Party (in the case of liabilities of the Owner hereunder) suffer such damages to a Third Party. The indemnification provisions in this Article VII shall be enforceable 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 strict liability imposed upon the Person seeking indemnification.

(c) Any indemnification payment hereunder shall be net of any third party insurance proceeds received by the Indemnified Party and the amount of indemnification payable under this Agreement shall not include the amount of any third party insurance proceeds actually recovered by the Indemnified Party with respect to a liability. If the amount to be netted hereunder from any payment by the Indemnifying Party is determined after the Indemnifying Party has already paid any amount required to be paid pursuant to this Agreement, the Indemnified Party shall repay to the Indemnifying Party, promptly after such determination, any amount that the Indemnifying Party would not have had to pay pursuant to this Agreement had such determination been made at the time of such payment.

(d) Nothing in this Agreement shall be construed to supersede or limit the indemnification rights and obligations in the Purchase Agreement.

This Exhibit shall govern the accounting procedures with regard to the billing costs incurred in connection with the performance by the Operators of the Services pursuant to this Agreement. These Accounting Procedures shall be effective throughout the term of this Agreement.

1. General Provisions

(a) Adjustments: Except as otherwise provided in this Agreement, the Owner’s payment of any invoices submitted by the Cenac Companies shall not prejudice the right of the Owner to protest or question the correctness or appropriateness thereof; provided, however, all invoices and statements rendered to the Owner under the Agreement shall conclusively be presumed to be true and correct after twenty (24) months following termination of the Agreement, unless prior to the end of said twenty-four month period the Owner takes written exception thereto and makes a claim against the Cenac Companies for adjustment.

Such payment shall include the Service Fee described below in Section 3, any necessary Direct Costs as described below in Section 4 and any Overhead Costs as described below in Section 5. It is the intent of the parties that services provided by Service Providers shall be billed by the Cenac Companies on a Direct Cost basis pursuant to Section 4 of this Exhibit B to the extent that it is feasible to measure and account for the services directly provided by such Service Providers to the Owner, by means of the accounting and internal control systems of the Owner and its Affiliates or by other methods approved by the Owner; and that Services not feasible to measure and account for on a Direct Cost basis shall be billed by the Cenac Companies as part of the Overhead Costs.

3. Service Fee. The Owner shall pay the Cenac Companies a monthly fee for services performed pursuant to this Agreement of $41,666.67, prorated for partial months (the “Service Fee”).

4. Direct Costs. The Owner shall reimburse or pay, as applicable, the following costs and expenses to the extent incurred by the Operators in providing the Services (“Direct Costs”):

(a) Salaries, Wages and Other Labor Costs: The salaries, wages and other labor costs (as specified below) of Employees (other than Stockholder) and other Service Providers directly engaged in and attributable to the provision of Services on a full-time basis (including any amounts paid as salaries, wages and labor costs of others temporarily employed in connection therewith).

Notwithstanding the foregoing, in no event shall the Owner be responsible for or have any obligation to reimburse either of the Cenac Companies (i) for any costs or liabilities incurred as a result of any violation of applicable Law or any error by either of the Cenac Companies in the course of operating or maintaining its employee compensation benefit plans and arrangements, including any excise taxes, penalties or similar liabilities incurred as a result of a violation of the Code, ERISA or the FLSA or (ii) for any increases in such costs or liabilities materially in excess of the increases experienced or implemented by similar companies in the marine transportation business.

(b) Payroll Taxes: Expenditures or contributions made by the Cenac Companies pursuant to assessments imposed by applicable Law, such as FICA taxes and federal or state unemployment taxes, which are applicable to salaries and wages chargeable under clause (a) above; provided, however, that in no event shall the Owner or any of its Affiliates be responsible for additional Taxes, interest or penalties of any kind resulting from any failure of either of the Cenac Companies or any of their respective

B-2

Affiliates to (i) properly classify a Service Provider for purposes of any Law, (ii) timely pay any applicable Taxes or (iii) otherwise comply with applicable Laws.

(c) Materials, Supplies, Tools and Miscellaneous Equipment: Any materials, supplies, tools and miscellaneous equipment purchased or furnished by the Cenac Companies for the benefit of the Owner shall be priced at cost.

(e) Outside Services: The cost of outside services and expertise, including legal, accounting and engineering fees, and fees from consultants, to the extent that the outside services rendered were for the benefit of the Owner in connection with providing the Services.

(f) Damages and Losses: To the extent not covered by insurance, all costs or expenses necessary for the repair or replacement of any Purchased Operations made necessary because of damages or losses incurred by fire, flood, earthquake, storm, theft, oil spills, accident, or other cause. The Cenac Companies shall furnish the Owner Notice of damages or losses incurred as soon as practicable after a report thereof has been received by the Owner.

(g) Insurance: Subject to Section 8.5, all costs and expenses, including deductibles and premiums, incurred by the Cenac Companies in connection with maintaining the Cenac Marine Policies during the Interim Period. With respect to the Cenac Employer Policies (during the Interim Period) and the policies provided for in Section 8.3, and subject in each case to Section 8.5, the costs and expenses incurred in connection with maintaining such policies with respect to Service Providers in their capacities as such, determined by pro rating such costs and expenses in the same proportion as the number of Service Providers then providing Services bears to the total number of persons to which such policies relate.

5. Overhead Costs: Overhead costs consist of costs and expenses incurred by the Operators in providing the Services other than Direct Costs described in Section 4 above, including the salaries, wages and other labor costs of Employees (other than Stockholder) and other Service Providers engaged in and attributable to the provision of Services on less than a full-time basis, mailing and stationary, computer and data processing, office administration and maintenance and the use of office equipment.

Example Built-In Gain Indemnity Calculation

Assumptions:

(1) Cenac Towing makes an S election, effective on or before July 1, 2008;

(2) Buyer purchases the Towing Assets from Cenac Towing on February 1, 2008 in exchange for cash, the Towing Limited Partner Units and the assumption of certain liabilities of Cenac Towing;

(3) Pursuant to Section 5.11 of the Agreement, each Towing Asset acquired from Cenac Towing is treated for federal income tax purposes as in part sold to the Partnership in a Taxable Sale and in part contributed to the Partnership in a Contribution; the portions of the Towing Assets treated as part of a Taxable Sale are referred to as the “Purchased Towing Assets” and the portions of the Towing Assets treated as part of a Contribution are referred to as the “Contributed Towing Assets;”

(4) On the Closing Date, the aggregate fair market value of the portions of the Contributed Towing Assets exceeds the aggregate tax basis of the Contributed Towing Assets by $100 million;

(5) In 2010, Cenac Towing sells 20% of the Towing Limited Partner Units;

(6) In 2013, the Partnership sells 100% of the Towing Assets; the portion of the Partnership’s gain on that sale that is attributable to the Contributed Towing Assets exceeds $100 million; and

(7) In 2013, the maximum federal income tax rate on corporations is 35%.

Built-In Gain Indemnity calculation with respect to the Taxable Sale and Contribution in 2008: $0.

Built-In Gain Indemnity calculation with respect to the sale of Towing Limited Partner Units in 2010: $0.

Built-In Gain Indemnity calculation with respect to the sale of Contributed Towing Assets in 2013: ($100,000,000 Asset Gain Amount x 80% retained Towing Limited Partner Units x 35% maximum corporate tax rate)/(100% — 35% maximum corporate tax rate) = $43,076,923

The foregoing example is solely for illustrative purposes and is not intended to take into account all factors that may be relevant to the calculation of the indemnity in a particular situation. As of the date of the Agreement, no determination has been made of the allocation of liabilities assumed, or other consideration paid, between Taxable Sales and Contributions under Section 5.11 of the Agreement or of the amount of any gain that might be realized by Cenac Towing under any circumstances. In the event of any inconsistency between this Exhibit and the Agreement or any provision thereof, the Agreement shall control.
