2.2 Right of First Refusal. In the event HSM proposes to enter into a transportation services agreement with a Third Party upon the termination of this Agreement for reasons other than a default by MPC or any other termination of this Agreement initiated by MPC pursuant to this Agreement, HSM shall give MPC ninety (90) days’ prior written notice of any proposed new transportation services agreement with a Third Party, which notice shall include details of all the material terms and conditions of such proposed transportation services agreement, subject to applicable confidentiality agreements.

ARTICLE III

PERFORMANCE OF TRANSPORTATION SERVICES

3.1 Agreement to Provide Transportation Services.

(a)During the Term and upon receipt of MPC’s oral or written request for Transportation Services, HSM shall provide (i) transportation services to MPC to transport Cargoes on the inland and coastal waters of the United States using the towboats, barges, and other equipment owned or operated by HSM as set forth on Exhibit C, as may be updated during the Term by HSM providing to MPC a Memorandum to File that adds or removes items of equipment (collectively, the “Equipment”), and (ii) mooring services for barges (i.e., fleeting services); Tankerman Services for the assurance of safe transfer of Cargo; cleaning services for Cargo tanks, voids, boat bilges and fuel/slop tanks; and routine repair and maintenance services performed at MPC’s facilities (collectively, the “Transportation Services”).

(b)This Agreement to provide Transportation Services does not preclude HSM from marketing its Transportation Services to third parties, provided that said marketing does not interfere with, or reduce its obligations to provide MPC’s requested Transportation Services under paragraph 3.1(a) herein.

(c)Equipment shall be loaded or discharged at any safe place or berth, or alongside vessels designated by MPC provided that the Equipment is always safely afloat. MPC shall provide the Equipment with a safe berth at MPC loading and discharging ports. Without prejudice to MPC’s foregoing obligation to provide a safe berth, HSM may determine, in its sole discretion, whether a loading or discharge berth is unsafe, and HSM shall not be liable for any Claims and Liabilities resulting from such determination.

3.2 Operations. At all times during the Term, HSM shall control and direct the Equipment and the crew of such Equipment and HSM shall:

(a) use reasonable care in material compliance with Applicable Laws and applicable agreements in providing the Transportation Services;

(b)use due diligence to ensure that the Equipment, to the extent applicable, (i) is seaworthy and prudently manned, maintained, equipped and supplied; (ii) is suitable for the specified Cargo; (iii) has fully functioning safety valves, overfill prevention system, fire suppression system, and automatic identification system transponder; (iv) is vapor tight (with certificates of vapor tightness provided to MPC upon request and updated according to Applicable Law); and (v) has no manifolds between compartments containing gasoline and distillate respectively;

(c)as soon as practical, notify MPC of any accidents, whether or not damage is obvious, occurring in the performance of the Transportation Services and promptly furnish MPC with a written report of all of the circumstances of any such accident; and

(d)in the event HSM arranges to have a surveyor attend and/or inspect the Equipment and/or any damage or other event or incident arising from or relating to this

Agreement, provide MPC as much advance notice of any such survey as is practical under the circumstances, to enable MPC personnel to attend such survey and/or arrange to appoint its own surveyor.

3.3 Additional Transportation Service. If MPC requests in writing to HSM a transportation service not covered by the Transportation Services being provided pursuant to this Agreement as of the date of the request, and HSM agrees to provide such service, then the Parties will negotiate in good faith an amendment to Exhibit B or Exhibit G, as applicable, to include the additional transportation service (each such service an “Additional Transportation Service”), the terms and conditions for the provision of each Additional Transportation Service and the Monthly Payment payable to MPC for each Additional Transportation Service, such Monthly Payment to be determined with the intent that it reflects an arm’s length standard.

3.4 Modification; Third Party Providers.


(a)	Any requests or other communications from a Party to another Party regarding (i)

the Transportation Services (ii) any modification or alteration to the provision of the Transportation Services or (iii) the provision of an Additional Transportation Service must be made by an Authorized Representative (it being understood that the receiving Party shall not be obligated to agree to any modification or alteration requested thereby).


(b)	The Parties understand and agree that MPC may contract with any Third Party to

provide equipment and/or transportation services that are not included in Equipment or Transportation Services under this Agreement. Further, any costs or expenses to be incurred in connection with obtaining such equipment or transportation services from a Third Party shall be paid by MPC; provided, however, that pursuant to the Amended and Restated Management Services Agreement HSM shall use commercially reasonable efforts to assist MPC in contracting for and vetting and managing such Third Party equipment or transportation services and shall communicate to MPC in advance the expected costs or expenses to be incurred.

3.5 Disclaimer of Warranties. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, HSM MAKES NO, AND EXPRESSLY DISCLAIMS ANY, WARRANTIES WHATSOEVER WITH RESPECT TO THE TRANSPORTATION SERVICES AND THE EQUIPMENT, INCLUDING ANY (A) WARRANTY OF MERCHANTABILITY; OR (B) WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE; OR (C) WARRANTY OF TITLE; OR (D) WARRANTY AGAINST INFRINGEMENT OF INTELLECTUAL PROPERTY RIGHTS OF A THIRD PARTY; WHETHER EXPRESS OR IMPLIED BY LAW, COURSE OF DEALING, COURSE OF PERFORMANCE, USAGE OF TRADE OR OTHERWISE.

3.6 Force Majeure.

(a)As soon as possible following the occurrence of a Force Majeure Event, HSM will provide MPC with written notice of the occurrence of such Force Majeure Event (a “Force Majeure Notice”). Concurrent with that notice or as soon as possible thereafter, HSM will give MPC a full description of the Force Majeure Event and the approximate length of time that HSM reasonably believes such Force Majeure Event will continue (the “Force Majeure Period”). Each Party shall use commercially reasonable efforts to mitigate or overcome the effects of a Force Majeure Event as soon as possible; provided, however, that neither Party shall be required to settle any strike, walkout, lockout or other labor dispute on terms which, in the reasonable judgment of the affected Party, are contrary to its interest. It is understood that the settlement

of a strike, walkout, lockout or other labor dispute will be entirely within the discretion of the affected Party.

(b)If HSM notifies MPC that it reasonably believes that the Force Majeure Period will continue for more than twelve (12) consecutive months for specified Equipment, then either Party may give the other Party notice of intent to terminate this Agreement with respect to the affected Equipment (a “Termination Notice”) at least twelve (12) months prior to the expiration of the Force Majeure Period; provided, however, that such Termination Notice shall be deemed canceled and of no effect if the Force Majeure Period ends prior to the expiration of such twelve (12) month period.

(c)Notwithstanding the foregoing, if MPC delivers a Termination Notice to HSM (the “MPC Termination Notice”) and, within thirty (30) days after receiving such MPC Termination Notice, HSM notifies MPC that HSM reasonably believes that it will be capable of fully performing its obligations under this Agreement within thirty (30) calendar days, then the MPC Termination Notice shall be deemed revoked and the applicable portions of this Agreement shall continue in full force and effect as if such MPC Termination Notice had never been given.

3.7 Material Safety Data Sheets. MPC has provided to HSM the current Material Safety Data Sheet or Safety Data Sheet (“SDS”) for each Product to be transported by HSM. MPC shall not be required to provide a SDS at each load. In the event that a new SDS becomes available for a particular Product, MPC shall promptly notify HSM and promptly provide the new SDS to HSM. HSM acknowledges that lethal levels of hydrogen sulfide gas and/or other petroleum, chemical or related product fumes, such as benzene, may be present in the vapor space within storage tanks and other compartments that contain asphalt and other heavy oil cargoes or certain other petroleum, chemical, or related products, such as benzene or coal tar light oil. In areas adjacent to or in close proximity to areas where such tanks and compartments vent, precautions must be taken against inhalation of hydrogen sulfide gas and/or other chemical fumes. Odor is not a reliable means of hydrogen sulfide gas or chemical fume detection. Consultation of the SDS for product and other descriptions and the rules and regulations of the Occupational Safety & Health Administration for protective measures is the responsibility of HSM. HSM acknowledges that it will provide warnings and safe handling information about hydrogen sulfide gas and other applicable chemical fumes to HSM’s employees, agents, contractors and invitees, and will require them to further communicate the warnings and information to all persons that they reasonably foresee may be exposed to or handle any Cargo that may contain hydrogen sulfide gas or other chemical fumes. HSM further acknowledges that it is responsible for determining, implementing, and ensuring compliance with work procedures to provide adequate precautions against hydrogen sulfide gas and other applicable chemical fumes exposure by HSM’s employees, agents, contractors and invitees.

3.8 No Partnership. This Agreement shall not be interpreted or construed to create an association, partnership, joint venture, employment or fiduciary relationship or similar relationship between HSM and MPC. Except as explicitly set forth in this Agreement, neither Party shall have any right, power or authority to enter into any agreement or undertaking for, act on behalf of, act or be an agent or representative of, or otherwise bind, the other Party. HSM shall act as an independent contractor in the performance of its duties hereunder.

3.9 Title; Risk of Loss. Notwithstanding the simple negligence, gross negligence or willful actions of HSM, and subject to Section 5.8, risk of loss or damage to Cargoes will at all times remain with MPC. Further, as between HSM and MPC, title to the Cargoes will at all times remain with MPC.

applicable tax authority, or (b) a new or change in Applicable Law, then MPC shall reimburse HSM for the additional taxes due from HSM, including interest and penalty. MPC has the right to contest with the tax authority, at MPC’s sole expense, the amount of any taxes or the result of any audit. HSM is responsible for any penalty or interest resulting from its failure to remit any invoiced taxes. Notwithstanding anything in this Agreement to the contrary, this Section 4.6 will, to the fullest extent permitted by Applicable Laws, survive the termination of this Agreement and remain in effect until the expiration of the relevant statute of limitations.

ARTICLE V

AVAILABILITY OF EQUIPMENT

5.1 Disruption of Transportation Services. HSM shall promptly notify MPC of any anticipated partial or complete disruption of a Transportation Service, other than a disruption due to a Force Majeure Event (notice of which shall be given in accordance with Section 3.6(a)), that is reasonably expected to extend for more than twenty-four (24) hours, including relevant information about the nature, extent, cause and expected duration of the disruption and the actions HSM is taking to resume full operations; provided, however, that HSM shall not have any liability for any failure to notify, or delay in notifying, MPC of any such matters except to the extent MPC has been materially damaged by such failure or delay. HSM shall provide MPC with at least ninety (90) days’ notice of any planned maintenance or repair activity on the Equipment that HSM determines will significantly reduce the Transportation Services.

5.2 Acceptance of Cargo. Subject to the terms of this Agreement and to disruptions for routine testing, inspection, repair and maintenance consistent with industry standards; scheduling requirements; and any requirements of Applicable Law; HSM shall accept for shipment all Cargo that meets applicable industry standard quality specifications. HSM may, without prejudice to any other remedy available to HSM, reject and return to MPC any Product that does not conform to such specifications, even after delivery to HSM.

5.3 Mechanical Availability of Equipment.

(a)Mechanical Availability Calculation. Promptly after the end of each Mechanical Availability Calculation Period and the Final Mechanical Availability Calculation Period, HSM shall calculate the Mechanical Availability individually for the Towboat Group and the Barge Group pursuant to Exhibits E and F.

(b) Mechanical Availability Credit. If the Mechanical Availability of the Towboat Group or Barge Group is below ninety-five percent (95%) for a Mechanical Availability Calculation Period, then MPC will receive a Credit calculated pursuant to Exhibits E and F. The Credit, if any, shall be offset against the Monthly Payment due to HSM in the month immediately following the month of the Mechanical Availability Calculation Period.

5.4 Restoring Transportation Services. HSM shall make such repairs and take such reasonable actions as are necessary to restore any disruption to those Transportation Services described in Section 3.1(a)(i). All such restoration shall be at HSM’s cost and expense unless the damage or event was caused by MPC or MPC’s employees, Affiliates, representatives, agents or customers. If for any reason, other than a disruption due to Force Majeure, HSM fails to provide at least ninety-five percent (95%) of the requested Transportation Services described in Section 3.1(a)(i) and the agreed Additional Transportation Services for a period of thirty (30) consecutive days, then either Party has the right to call a meeting between executives of both Parties by providing at least two (2) business days’ prior written notice.

5.5 No Demise and No Control by MPC. Nothing in this Agreement shall be construed as creating a demise of the Equipment to MPC or as vesting MPC with any control over the physical operation or navigation of the Equipment. HSM shall control and direct all tankermen provided by HSM. As between HSM and MPC, all such tankermen shall be deemed for all purposes not to be an employee of MPC.

5.6 Inspection/Vetting. Upon reasonable advance notice to HSM, MPC may inspect the Equipment at a loading or discharging berth, or other location which will not substantially interfere with the operation of the Equipment, and may, at HSM’s offices, review HSM’s safety, environmental protection, and maintenance programs and procedures. If MPC determines, based on such inspection or review, that a material, unsatisfactory safety or operational condition exists, then MPC may provide HSM with written notice of such condition and the basis for MPC’s determination of the same. If HSM agrees with MPC’s determination, then HSM shall provide a written explanation of its cure, including the estimated time to cure. If HSM reasonably disagrees with MPC’s determination, then HSM shall provide MPC with written notice of its disagreement and the basis therefor, and the Parties shall negotiate in good faith to resolve such disagreement. HSM shall afford all necessary cooperation and accommodation; provided, however, that neither the exercise nor the non-exercise by MPC of such right shall in any way reduce HSM’s authority over, and responsibility for, the Equipment and every aspect of its operation, nor increase MPC’s responsibilities to HSM or Third Parties for the same, and shall not be construed as an assumption by MPC of responsibility for the safety of the vessel and its crew or for liability to Third Parties.

5.7 Cargo Transfer. Before and after any Cargo transfer, HSM shall inspect moorings, hoses and appurtenances. HSM shall be responsible for handling, inspecting, bleeding, attaching and detaching all hoses and lines from the shore connection to the Equipment in a safe and prudent manner. During Cargo transfer, HSM shall continuously monitor flow rate, connections, and barge tank levels. HSM shall measure and legibly document barge compartment levels both before and after Cargo transfer. MPC shall pump Cargo into the Cargo tanks of the Equipment at MPC’s expense, and HSM shall pump Cargo out of the Cargo tanks at MPC’s expense. The Cargo will be safely loaded and discharged at such rates, pressures and temperatures required by design of the Equipment, or the receiving terminal, as appropriate, and/or good operating practice with respect to such Equipment, or the receiving terminal, as appropriate.

5.8 Loss in Transit. HSM shall reimburse MPC for in transit loss of Cargo in excess of one-half percent (0.5%) by volume, or such other percentage as the Parties may agree in writing shall apply to certain Products (“In Transit Loss Allowance”). HSM shall not be liable for any such loss unless (a) the cause for the loss in transit is unknown, (b) MPC or MPC’s agent provides written notice of such loss to HSM within thirty (30) days of unloading the relevant Cargo and (c) a comparison of Equipment ullage figures at loading port and at discharge port, as measured by a Third Party inspector, which shall be mutually agreed to by both MPC and HSM, establishes that a volume loss in excess of the In Transit Loss Allowance has actually occurred in transit. The amount payable by HSM to MPC for any such in transit loss shall be an amount equal to (x) the volume loss in excess of the In Transit Loss Allowance, multiplied by (y) the per unit spot value of the relevant product using an appropriate industry market index for the delivery location reference market.

5.9 Audit. HSM shall retain all records and accounts related to the Transportation Services

provided herein for at least three (3) years from the completion date of any Transportation Service. HSM shall permit MPC access at reasonable times and upon reasonable advance notice,

but not more often than once in any calendar year, to review and audit all records and accounts relating to the Transportation Services provided under this Agreement at MPC’s sole cost and expense. Any audit of a particular calendar year must commence during the one (1) year period (or such longer period as the Parties may agree) following the end of such year.

Notwithstanding anything in this Agreement to the contrary, MPC is not responsible for indemnification obligations pursuant to Section 7.2 for any cause of action arising from the actions, inactions, admissions, or omissions of any personnel provided or caused to be provided to HSM pursuant to the Amended and Restated Employee Services Agreement, provided the Amended and Restated Employee Services Agreement is still in effect at the time the cause of action arose. MPC is responsible for indemnification obligations pursuant to Section 7.2 for any cause of action arising from the grossly negligent or willful actions, inactions, admissions, or omissions of any personnel provided or caused to be provided to HSM pursuant to the Amended and Restated Employee Services Agreement, provided the Amended and Restated Employee Services Agreement is still in effect at the time the cause of action arose.

7.4 Limitations and Liability.

(a)Each Party has a duty to mitigate any loss sustained under this Agreement.

(b)IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL (INCLUDING LOSS OF REVENUES OR PROFITS, LOSS OF DATA, LOSS OF GOODWILL AND LOSS OF CAPITAL, WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES), EXEMPLARY OR PUNITIVE DAMAGES OR THE LIKE (EXCEPT TO THE EXTENT THAT SUCH DAMAGES ARE PAID TO A THIRD PARTY AS A RESULT OF A THIRD PARTY CLAIM) ARISING UNDER ANY LEGAL OR EQUITABLE THEORY OR ARISING UNDER OR IN CONNECTION WITH THIS AGREEMENT (OR THE PROVISION OF SERVICES HEREUNDER), ALL OF WHICH ARE HEREBY EXCLUDED BY AGREEMENT OF THE PARTIES REGARDLESS OF WHETHER OR NOT EITHER PARTY TO THIS AGREEMENT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

7.5 Indemnification Procedures.

(a)Within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification under this Article VII, the Indemnified Party will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim to the extent then known by the Indemnified Party.

(b)The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article VII, including the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no settlement involving the payment of money shall be entered into without the prior written consent of the Indemnified Party unless it includes a full release of the Indemnified Party from such claim; and provided further, that no settlement containing any form of injunctive or similar relief shall be entered into without the prior written consent of the Indemnified Party, which consent shall not be unreasonably delayed, conditioned or withheld.

(c)The Indemnified Party agrees to cooperate in good faith and in a commercially reasonable manner with the Indemnifying Party with respect to all aspects of the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification under this Article VII, including the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense and counterclaims, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party reasonably considers relevant to such defense and counterclaims, the making available to the Indemnifying Party of any employees of the Indemnified Party and the granting to the Indemnifying Party of reasonable access rights to the properties and facilities of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the Indemnified Party pursuant to this Section 7.5. The obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence shall not be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification set forth in this Article VII; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense and counterclaims. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense and counterclaims.

(d)In determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from Third Parties.

(e)Notwithstanding anything to the contrary hereunder, no cause of action, dispute or claim for indemnification may be asserted against any Party or submitted to arbitration or legal proceedings which accrued more than two (2) years after the later of (i) the occurrence of the act or event giving rise to the underlying cause of action, dispute or claim and (ii) the date on which such act or event was, or should have been, in the exercise of reasonable due diligence, discovered by the Indemnified Party.

7.6 Assumption of Risk. HSM acknowledges that environmental, health, and safety conditions, the existence of hazardous materials (including Cargo that may contain hydrogen sulfide gas and/or other petroleum, chemical or related product fumes), interaction with Third Party vessels and personnel, and other hazards, commonly exist at MPC’s work sites. Further, HSM acknowledges that its use of, and presence on, waterways, public property and Third Party property are beyond the control of MPC. HSM thus assumes the ordinary risks associated with the performance of the Transportation Services contemplated herein.

ARTICLE VIII

INSURANCE

8.1 Corporate Group Insurance. Without limiting the scope of any of HSM’s obligations or liabilities under this Agreement, MPC shall cause its affiliate Marathon Petroleum Corporation

(“Marathon”) to procure and maintain, in HSM’s name and at HSM’s sole cost and expense, and keep in effect during the Term, the following insurances within Marathon’s corporate wide policies with insurance companies designated by A.M. Best Company with a rating of A- or better.:

(a)If HSM has employees on its payroll and if further required by Applicable Laws to cover such employees, Workers’ Compensation and U.S. ▇▇▇▇▇▇▇▇▇ and Harbor Workers’ Compensation Act Insurance covering all its employees performing the Transportation Services, sufficient to comply fully with requirements and coverages specified by all Applicable Laws.

(b) Marine General Liability Insurance with contractual liability coverage for HSM’s indemnity obligations under this Agreement, and combined single limits of at least $2,000,000 per occurrence.

8.2 HSM Insurance. Without limiting the scope of any of HSM’s obligations or liabilities under this Agreement, HSM shall procure and maintain, or shall cause to be procured and maintained, in its name and at its sole cost and expense, and keep in effect during the Term, the following insurance with insurance companies designated by A.M. Best Company with a rating of A- or better:

(a) Pollution Insurance in an amount equal to the maximum carried by HSM, but never less than the amount necessary to comply with the minimum financial responsibility requirements established by any Applicable Law, or $100,000,000, whichever is greater.

(b) Protection and Indemnity Insurance with contractual liability coverage and sistership clause unamended, endorsed specifically to include (a) collision liability, (b) in rem claims, stating that such actions shall be treated as a claim against the insured in personam and (c) full crew coverage including wages, maintenance and cure, with a limit of at least $2,000,000 per occurrence.

(c) Tower’s Liability Insurance that covers all damages caused by said tow, by collision or otherwise, with a limit of at least $2,000,000 per occurrence.

Upon request from MPC, HSM shall provide supplements and amendments to such certificates to demonstrate that the insurance identified in Section 8.2(a) and endorsements remain in effect. MPC’s acceptance of an insurance certificate that does not comply with this Agreement does not waive any requirement of this Agreement.

8.4 Coverage by Third Parties. In the event HSM utilizes one or more Third Parties in the performance of its fleeting, tankermen or cleaning and repair facility services hereunder, HSM shall ensure that such Third Parties maintain insurance coverage of the types and amounts herein

established that are applicable to the services to be provided by such Third Parties. Upon request from MPC, HSM shall provide to MPC, prior to the use of any such services, certificates of insurance evidencing such coverage.

ARTICLE IX

VESSEL VETTING AND VESSEL RESPONSE PLAN

9.1 Pollution. HSM shall comply with the Marathon Petroleum Vetting Policy and shall maintain and implement a Vessel Response Plan (“Plan”) for the prevention and removal of pollution from water and natural resources, as required by any Applicable Law. Such Plan shall include appropriate response contractors to comply with Applicable Law. In the event of an unintentional discharge or significant threat of an unintentional discharge of Cargo transported under this Agreement, HSM shall promptly implement its Plan and undertake all such measures as may be reasonably necessary to prevent or mitigate pollution damage and perform all appropriate mitigation, regulatory notifications, and response. Additionally, HSM shall promptly notify MPC of any such unintentional discharge of Cargo. In the event an unintentional discharge of Cargo transported under this Agreement occurs, MPC may, at its option, but without obligation, and upon written notice to HSM, undertake such measures as are reasonably necessary to prevent or mitigate pollution damage resulting from such discharge. MPC shall keep HSM advised in advance in writing of the nature of the measures intended to be taken by it. Any of the aforementioned measures actually taken by MPC will be at HSM’s expense except to the extent that such discharge was caused by MPC, in which case such measures shall be for MPC’s expense. HSM agrees that it will not raise or plead as a defense to a claim for reimbursement by MPC that in undertaking or performing such measures, MPC acted as a volunteer and any such defense of “volunteer” is hereby waived by HSM. These provisions are not in derogation of any other right MPC or HSM may have under this Agreement or otherwise have or acquired under Applicable Law.

ARTICLE X

This Agreement shall be binding upon and inure to the benefit of the Parties and their permitted successors and assigns; provided, however, that neither Party may assign its rights or obligations under this Agreement without prior written consent from an Authorized Representative of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed; provided further, however, that either Party may assign its rights and obligations under this Agreement to a successor in interest resulting from any merger, reorganization, consolidation or as part of a sale of all or substantially all of its assets. Subject to the foregoing, this Agreement shall bind and inure to the benefit of each Party and its successors and permitted assigns.

MISCELLANEOUS

12.1 Choice of Law; Dispute Resolution.

(a)Governing Law. This Agreement shall be subject to and governed by the laws of the State of New York, without regard to the conflict of laws provisions thereof to the extent such principles or rules would require or permit the application of the laws of any other jurisdiction.

(b)Mediation. If the Parties cannot resolve any Dispute or claim arising under this Agreement, then no earlier than ten (10) days nor more than sixty (60) days following written notice to the other Party, either Party may initiate mandatory, non-binding mediation hereunder by giving a notice of mediation (a “Mediation Notice”) to the other Party. In connection with any mediation pursuant to this Section 12.1(b), the mediator shall be jointly appointed by the Parties and the mediation shall be conducted in Findlay, Ohio unless otherwise agreed by the Parties. All costs and expenses of the mediator appointed pursuant to this section shall be shared equally by the Parties. The then-current Model ADR Procedures for Mediation of Business Disputes of the Center for Public Resources, Inc., either as written or as modified by mutual agreement of the Parties, shall govern any mediation pursuant to this Section 12.1(b). In the mediation, each Party shall be represented by one or more senior representatives who shall have authority to resolve any Disputes. If a Dispute has not been resolved within thirty (30) days after the receipt of the Mediation Notice by a Party, then any Party may refer the resolution of the Dispute to any federal or state court located in Ohio in accordance with Section 12.1(c).

(c)Litigation.

The foregoing consents to jurisdiction and service of process shall not constitute general consents to service of process in the State of Ohio for any purpose except as provided herein and shall not be deemed to confer rights on any Person other than the Parties.

12.2 Waiver. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the Party entitled to the benefit thereof. Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any Party, it is in writing signed by an Authorized Representative of such Party. The failure of any Party to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, or in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach. No single or partial exercise of any right or remedy under this Agreement precludes any simultaneous or subsequent exercise of any other right, power or privilege.

12.3 Cumulative Remedies. The rights and remedies set forth in this Agreement are not exclusive of, but are cumulative to, any rights or remedies now or subsequently existing at law, in equity or by statute.

12.7 Mutual Obligations of Confidentiality.

(a)During the Term and for a period of three (3) years after the termination of this Agreement, each Party shall keep confidential the other Party’s Confidential Information, whether acquired before or after the Effective Date, and neither Party shall (i) use the other Party’s Confidential Information except in connection with the performance of its obligations under this Agreement or (ii) release or disclose the other Party’s Confidential Information to any Third Party other than a receiving Party’s representatives with a need to know the Confidential Information for the purposes of such Party’s performance pursuant to this Agreement.

(b)Each Party will be responsible for any breach of the provisions of this Section 12.7 by its representatives.

(c)The provisions of Section 12.7 do not apply to any Confidential Information to the extent that the receiving Party is required to disclose such information under any Applicable Laws or pursuant to any order of any court, mediator or arbitrator, or in connection with any legal proceeding, mediation or arbitration to enforce its rights under this Agreement, or in connection with the requirements of a regulatory body or stock exchange, or in connection with a financing, bond offering, or sale of stock.

(d)If a Party receives a subpoena or other demand for disclosure of Confidential Information received from any other Party or must disclose to a Governmental Authority any Confidential Information received from such other Party in order to obtain or maintain any required governmental approval, the receiving Party shall, to the extent legally permissible, provide notice to the providing Party before disclosing such Confidential Information. Upon receipt of such notice, the providing Party shall promptly either seek an appropriate protective order, waive the receiving Party’s confidentiality obligations hereunder to the extent necessary to permit the receiving Party to respond to the demand, or otherwise fully satisfy the subpoena or demand or the requirements of the applicable Governmental Authority. If the receiving Party is nonetheless legally compelled to disclose such Confidential Information or if the providing Party does not promptly respond as contemplated by this section, the receiving Party may disclose that portion of Confidential Information covered by the subpoena or other demand.

(e)Each Party acknowledges that the disclosing Party would not have an adequate remedy at law for the breach by the receiving Party of any one or more of the covenants contained in this Section 12.7 and agrees that, in the event of such breach, the disclosing Party shall, in addition to the other remedies that may be available to it, be entitled to injunctive relief for any violation of, and to enforce the terms of, this Section 12.7

12.8 Severability. The provisions of this Agreement are separable and severable. Wherever possible, each provision hereof shall be interpreted in such a manner as to be effective and valid under Applicable Law. If any one or more of the provisions contained herein is, for any reason, held to be invalid, illegal or unenforceable in whole or in part by any court of law or equity, then such provision or provisions shall be ineffective to the extent, but only to the extent, of such

invalidity, illegality or unenforceability without invalidating the remainder of such provision or provisions or any other provisions hereof, unless such a construction would be unreasonable and the remaining provisions hereof shall continue in full force and effect to the greatest extent practicable.

12.9 Survival. Notwithstanding any suspension or termination of this Agreement, the Parties shall continue to be bound by the provisions of this Agreement that reasonably require some action or forbearance after such suspension or termination, including without limitation those relating to confidentiality obligations, audit rights, warranties, compliance with Applicable Laws, governing law, dispute resolution, indemnities, and limitation of liability.

12.10 Entire Agreement. This Agreement constitutes the entire agreement between the Parties with respect to the subject matter hereof, and supersedes all prior agreements, negotiations, discussions, understandings and commitments, written or oral, between the Parties with respect to such subject matter.

12.11 Amendment. This Agreement can only be amended, modified or supplemented by a written instrument signed by an Authorized Representative of the Parties.

12.12 Counterparts. This Agreement may be executed by the Parties in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute but one and the same instrument. Executed facsimiles of such counterparts shall be deemed enforceable to the same extent as if they were executed original documents.

TOWBOAT MECHANICAL AVAILABILITY CALCULATION and

TOWBOAT CREDIT CALCULATION


1.	Towboat Mechanical Availability Metric: A towboat is deemed 100% mechanically available if it can perform work at any given time. The towboat is not required to be active, but it must be available to do work.


2.	Calculation of Towboat Group Mechanical Availability:

(a)

Mechanical Availability is the percentage of time Equipment in the Towboat Group not under Force Majeure is capable of performing work during a Mechanical Availability Calculation Period. A towboat is deemed not capable of performing work during periods of scheduled downtime and unscheduled downtime. In accordance with the latest version of HSM’s Boat Mechanical Availability Metric Definition Document, HSM will gather data for this calculation from various sources, including but not limited to: (i) the HSM operation status updates (ii) HSM daily marine traffic reports (iii) HSM Maintenance Supervisor statements, and (iv) towboat activity logs.

(b) Mathematically the formula is expressed as follows:



		n
		∑ (h_i- f_i - s_i-u_i)
		i=1
Mechanical Availability (%) =
Mechanical Availability (%) =
		n
		∑ (h_i - f_i)
		i=1

Where:

i=each individual towboat identified as Equipment in the Towboat Group at any time during the Mechanical Availability Calculation Period

n=the number of towboats identified as Equipment in the Towboat Group at any time during the Mechanical Availability Calculation Period

h=number of hours each individual towboat (i) is in the Towboat Group during the Mechanical Availability Calculation Period

f=number of hours each individual towboat (i) in the Towboat Group during the Mechanical Availability Calculation Period is under Force Majeure

s= number of hours each individual towboat (i) in the Towboat Group during the Mechanical Availability Calculation Period has encountered scheduled downtime

u= number of hours each individual towboat (i) in the Towboat Group during the Mechanical Availability Calculation Period has encountered unscheduled downtime

Scheduled downtime means towboat unavailability to perform work due to scheduled mechanical activities such as regulatory inspections, planned maintenance/repairs, dry docking, overhaul or other planned work. Scheduled downtime begins when a towboat is dry docked or physically unable to perform transportation services at the start of the planned maintenance/repair work (including cleaning or preparation work), as appropriate, and ends when a towboat is capable of moving a Cargo.

Unscheduled downtime means towboat unavailability to perform work due to unscheduled mechanical activities such as equipment malfunctions, process failures, and downtime associated

D-1

with accidents. Unscheduled downtime does not include Force Majeure Events or circumstances such as weather related events/delays, lock delays, traffic delays, loading/unloading delays, demurrage time, unplanned drills/inspections, fueling, routine maintenance, etc. Unscheduled downtime begins when a towboat is not capable of moving a Cargo or performing work and ends when such towboat is capable of moving a Cargo or performing work.

3. Calculation of Credit for Towboat Group

(a) If Mechanical Availability for the Mechanical Availability Calculation Period ≥ 95% then MPC is not due a Credit for Mechanical Availability

(b) If Mechanical Availability for the Mechanical Availability Calculation Period < 95% then MPC is due a Credit for Mechanical Availability calculated as follows:

[95%-MA] * ∑ [(r_i* (d_i- f_i)]

i=1

Where:

MA=Mechanical Availability for the Mechanical Availability Calculation Period

i=each individual towboat identified as Equipment in the Towboat Group at any time during the Mechanical Availability Calculation Period

n=the number of towboats identified as Equipment in the Towboat Group at any time during the Mechanical Availability Calculation Period

r=the day rate for each individual towboat (i) in the Towboat Group during the Mechanical Availability Calculation Period

d= number of days* each individual towboat (i) is in the Towboat Group during the Mechanical Availability Calculation Period

f=number of days* each individual towboat (i) in the Towboat Group during the Mechanical Availability Calculation Period is under Force Majeure

* A day can be partial, e.g., 15 hours = .625 days

4. For illustration purposes, the following is a sample calculation based on the listed assumptions using full days (24 hours):


I.	Assumptions:


1)	Mechanical Availability Calculation Period January 1-December 31


2)	Towboat #1


a.	On Exhibit C as Equipment January 1- December 31 (365 days)

4)	Towboat #3


a.	On Exhibit C as Equipment July 1-December 31 (184 days)


b.	July 1-September 15 capable to do work (77 days)


c.	September 16-September 21 unscheduled downtime (6 days)


d.	September 22-December 31 capable to do work (101days)


e.	Day Rate=$7000


5)	Towboat #4


a.	On Exhibit C as Equipment May 1-December 31 (245 days)


b.	May 1-May 31 capable to do work ( 31 days)


c.	June 1-June 10 scheduled downtime (10 days)


d.	June 11-December 26 capable to do work (199 days)


e.	December 27-December 31 Force Majeure (5 days)


f.	Day Rate=$7000


II.	Example calculation of Mechanical Availability for Towboat Group



Towboat Group	(365+90+184+245)- (31+0+0+5) -(15+0+0+10)- (10+7+6+0)
Mechanical =		= 94.34%



Availability	(365+90+184+245)- (31+0+0+5)


III.	Example calculation of the Credit for Towboat Group


1)	If the Towboat Group Mechanical Availability was equal to or greater than 95% no Credit would be due for the example Mechanical Availability Calculation Period


2)	Since the Towboat Group Mechanical Availability is less than 95% in this example, a Credit is due and needs to be calculated.


3)	Calculation of Credit for Towboat Group is as follows:

[95%-94.34%] * [($6000* (365-31)) + ($7000* (90-0))- ($7000* (184-0))+ ($7000* (245-5))] = $36,973.20

BARGE MECHANICAL AVAILABILITY CALCULATION and

BARGE CREDIT CALCULATION


1.	Barge Mechanical Availability Metric: A barge is deemed 100% mechanically available if it can perform work at any given time. The barge is not required to be active, but it must be available to do work.


2.	Calculation of Barge Group Mechanical Availability:

(a)

Mechanical Availability is the percentage of time Equipment in the Barge Group not under Force Majeure is capable of performing work during a Mechanical Availability Calculation Period. A barge is deemed not capable of performing work during periods of scheduled downtime and unscheduled downtime. In accordance with the latest version of HSM’s Barge Mechanical Availability Metric Definition Document, HSM will gather data for this calculation from various sources, including but not limited to: (i) the HSM barge inspector reports (ii) HSM maintenance planning meetings, and (iii) operations and maintenance management systems.


(b)	Mathematically the formula is expressed as follows:



		n
		∑ (h_i- f_i - s_i-u_i)
		i=1
Mechanical Availability (%) =
Mechanical Availability (%) =
		n
		∑ (h_i - f_i)
		i=1

Where:

i=each individual barge identified as Equipment in the Barge Group at any time during the Mechanical Availability Calculation Period

n=the number of barges identified as Equipment in the Barge Group at any time during the Mechanical Availability Calculation Period

h=number of hours each individual barge (i) is in the Barge Group during the Mechanical Availability Calculation Period

f=number of hours each individual barge (i) in the Barge Group during the Mechanical Availability Calculation Period is under Force Majeure

s= number of hours each individual barge (i) in the Barge Group during the Mechanical Availability Calculation Period has encountered scheduled downtime

u= number of hours each individual barge (i) in the Barge Group during the Mechanical Availability Calculation Period has encountered unscheduled downtime

Scheduled downtime means the cumulative number of days that the barges are unavailable to perform work due to scheduled mechanical activities such as regulatory inspections, planned maintenance/repairs, dry docking, overhaul or other planned work. Scheduled downtime begins when a barge is docked or at the start of the planned maintenance/repair work (including cleaning or preparation work), as appropriate, and ends when a barge is capable of moving a Cargo.

F-1

Unscheduled downtime means barge unavailability to perform work due to unscheduled mechanical activities such as equipment malfunctions, process failures, and downtime associated with accidents. Unscheduled downtime does not include Force Majeure Events or circumstances such as weather related events/delays, lock delays, traffic delays, loading/unloading delays, demurrage time, unplanned drills/inspections, fueling, routine maintenance, etc. Unscheduled Downtime begins when a barge is docked prior to the beginning maintenance and repair, including cleaning and prep work and ends when such barge is capable of moving a Cargo or performing work.

3. Calculation of Credit for Barge Group

(a) If Mechanical Availability for the Mechanical Availability Calculation Period ≥ 95% then MPC is not due a Credit for Mechanical Availability

(b) If Mechanical Availability for the Mechanical Availability Calculation Period < 95% then MPC is due a Credit for Mechanical Availability calculated as follows:

[95%-MA] * ∑ [(r_i* (d_i- f_i)]
