14. DEFAULT AND TERMINATION

14.1 Termination for Default. A Party shall be in default under this Agreement if:

If a Party is in default as described above, then the other Party may: (i) terminate this Agreement upon notice to the defaulting Party; (ii) withhold any payments due to the defaulting Party under this Agreement; and/or (iii) pursue any other remedy at law or in equity.

14.2 Obligations at Termination. Upon the expiration or termination of this Agreement, (a) MPC shall promptly take delivery of all of its Product, except the Cavern Bottoms, from the Cavern and (b) MTS shall pay MPC for the value of the Cavern Bottoms, in either case within thirty (30) Days of such termination or expiration. In the event MPC does not take delivery of all of the Product, except the Cavern Bottoms, within such thirty (30) Day period, MPC shall be assessed a Monthly holdover storage fee on all Product, except the Cavern Bottoms, held in storage more than thirty (30) Days beyond the termination or expiration of this Agreement until

8

such time the entire volume of MPC’s Product, except the Cavern Bottoms, is removed from the Cavern. The Monthly holdover storage fee, if any, will be calculated on the same basis as the Storage and Transportation Fee; provided, however, that the Commitment will be reduced by a volume equal to the Cavern Bottoms.

15. FORCE MAJEURE

As soon as possible upon the occurrence of a Force Majeure, MTS shall provide MPC with written notice of the occurrence of such Force Majeure (a “Force Majeure Notice”). MTS shall identify in such Force Majeure Notice the approximate length of time that MTS believes in good faith such Force Majeure shall continue (the “Force Majeure Period”). If MTS advises in any Force Majeure Notice that it reasonably believes in good faith that the Force Majeure Period shall continue for more than twelve (12) consecutive Months, then, at any time after MTS delivers such Force Majeure Notice, either Party may terminate this Agreement upon delivery of a written notice to the other Party (a “Termination Notice”) twelve (12) Months (the “Notice Period”) after receipt of such Termination Notice; provided further; that such Termination Notice shall be deemed canceled and of no effect if the Force Majeure Period ends prior to the expiration of Notice Period. For the avoidance of doubt, neither Party may exercise its right under this Section 15 to terminate this Agreement as a result of a Force Majeure event if the Cavern’s ability to store the Commitment has been unaffected by the applicable Force Majeure event.

16. ASSIGNMENT; PARTNERSHIP CHANGE IN CONTROL

16.1 Assignment. Neither Party may assign its rights under this Agreement without prior written consent from the other Party, which consent shall not be unreasonably withheld; provided, however, that either Party may assign its rights 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 such Party’s assets. This Agreement shall inure to the benefit of, and be binding upon, the successors and assigns of both Parties.

16.2 Partnership Change in Control. MPC’s obligations hereunder shall not terminate in connection with a Partnership Change of Control. MTS shall provide MPC with notice of any Partnership Change of Control at least sixty (60) Days prior to the effective date thereof.

17. INSURANCE

During the Term, MTS shall maintain, at its expense, property and liability insurance coverage or self-insurance retentions that are, in its good faith judgment, commercially reasonable and otherwise adequate for its ownership and operation of the Cavern.

No waiver of any of the terms and conditions of this Agreement, or any breach thereof, will be effective unless in writing signed by a duly authorized individual on behalf of the Party against which the waiver is sought to be enforced. No waiver of any term or condition or of any breach of this Agreement will be deemed or will constitute a waiver of any other term or condition or of any later breach (whether or not similar), nor will such waiver constitute a continuing waiver unless otherwise expressly provided.

20.2 Entire Agreement. This Agreement constitutes the entire agreement among the Parties pertaining to the subject matter hereof and supersedes all prior agreements and understandings of the Parties in connection therewith.

20.3 Governing Law; Jurisdiction. This Agreement shall be governed by the laws of the State of Ohio without giving effect to its conflict of laws principles.

20.4 Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be valid and effective under Applicable Law, but if any provision of this Agreement or the application of any such provision to any Person or circumstance will be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision hereof, and the Parties will negotiate in good faith with a view to substitute for such provision a suitable and equitable solution in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

20.5 No Third Party Beneficiaries. It is expressly understood that the provisions of this Agreement do not impart enforceable rights in anyone who is not a Party or successor or permitted assignee of a Party.

11

20.6 WAIVER OF JURY TRIAL. EACH PARTY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDINGS RELATING TO THIS AGREEMENT OR ANY PERFORMANCE OR FAILURE TO PERFORM OF ANY OBLIGATION HEREUNDER.
