(e)    In the event that there is an Incident involving a TLLP Facility, which results in one or more of the Tesoro Parties incurring Tesoro Response Costs, then the TLLP Party operating the TLLP Facility for which such costs are incurred shall reimburse and indemnify the Tesoro Parties for the Tesoro Response Costs associated with such Incident; provided however, that such TLLP Party shall not be responsible for reimbursing or indemnifying the Tesoro Parties for any Tesoro Response Costs to the extent that the Incident was attributable to the to the negligent or wrongful actions or omission of such Tesoro Party for which the TLLP Party would have a right of recovery against such Tesoro Party under law, regulation, equity or contract.

TMC shall be responsible for reimbursing the appropriate Parties for such Incident Response costs to the extent that law, regulation, equity or contract would impose such liability upon TMC as a charterer of the vessel. If the Incident involves a TLLP Facility, the TLLP Parties shall be subrogated to the rights of TMC to recover from the vessel or its insurers the Incident Response Costs incurred by TLLP, either directly or by reason of a reimbursement of the Tesoro Parties pursuant to this Agreement.

(h)    In the event that TCI is charged for MSRC/MPA Response Costs relating to Incidents associated with facilities or operations of third parties that are unrelated to any facilities or operations of any of the Parties or vessels chartered or otherwise utilized by TCI, then the Parties shall negotiate a fair and equitable allocation of costs among themselves, based upon the nature of the costs and the Incident that resulted in the MSRC/MPA Response Costs and the respective relationships of the Parties with regard to such Incident.

(i)    In no event shall any allocation of Incident Response Costs be made or required hereunder that would cause the Incident to be regarded as more than one occurrence with respect to all of the Parties' collective insurance coverages or that would expose the Parties to multiple insurance deductibles or self-insured retentions or otherwise limit or exclude insurance coverage with respect to such Incident, nor shall any provision of this agreement or any condition of TCI's representation of the Parties as a member in MPA be construed to provide such a result. If any Party recovers any MSRC/MPA Response Costs from the owner, operator, charterer or insurer of

a vessel or any other third party or any insurer, then such recovery shall be credited against and reduce and/or provide reimbursement for any Incident Response Costs that otherwise might be owed or have been paid by the other Parties hereto.

(j)    This Agreement does not supersede or control over any allocation of Incident Response Costs that may be set forth in specific Operating Agreements, use and throughput agreements or other service agreements between the TLLP Parties and the Tesoro Parties regarding operation and use of the TLLP Facilities. The provisions of these agreements shall be harmonized with the provisions of this Agreement to the maximum extent possible. In the event of any conflict between the various terms, the provisions of the applicable Operating Agreement, use and throughput agreement or service agreement shall control over the terms of this Agreement.

5.    Additions to TLLP Facilities. The Parties anticipate that in the future, TLLP will acquire additional logistics facilities from Tesoro Parties or from third parties, and that the Parties may agree that the Tesoro Parties should provide oil spill contingency planning and response services for those additional facilities. Upon such acquisition and agreement, each such facility will automatically become a TLLP Facility, subject to this Agreement.

6.    Term and Termination. This Agreement shall continue until December 31, 2013 and shall renew for successive periods of one year thereafter, unless terminated by any Party upon sixty (60) days advance written notice. The Parties shall periodically evaluate whether the allocation of MPA Operating Costs set forth herein and the agreement not to include such MPA Operating Costs or MSRC Service Fees as components of tariffs and fees remains appropriate under conditions as they may exist from time to time. At any time after December 31, 2013, any Party may request renegotiation of all or any part of this Agreement, and the Parties shall then negotiate in good faith to make reasonable arrangements regarding future allocations of MPA Operating Costs, MSRC Service Fees and related adjustments of tariff and fee structures. In the event the Parties are unable to reach a consensus on any appropriate adjustments, then any Party may terminate this Agreement upon ten (10) days advance written notice as to subsequent costs incurred by TCI, but such termination shall not invalidate this Agreement as to costs incurred by TCI prior to the effective date of such termination. Upon any termination of this Agreement,

TCI may rescind its designation of the other Parties as covered entities with respect to TCI's membership in MPA.

7.    Parent Guaranties and COFRs. For TLLP Facilities that are operated by a TLLP Party, but are owned or leased by a Tesoro Party, then the Tesoro Party or its parent, Tesoro Corporation may be required to post or provide a parent guaranty or a Certificate of Financial Responsibility (“COFR”) to demonstrate adequate financial ability to pay for any Incident Response Costs that might be associated with Incidents at such TLLP Facility. The Tesoro Party owning or leasing such TLLP Facility shall be entitled to reimbursement for any such Incident Response Costs as provided herein, and Tesoro Corporation shall be (i) subrogated to the rights of such Tesoro Party to receive such reimbursement to the extent that Tesoro Corporation is obligated to pay or guarantee payment of such Incident Response Costs pursuant to any such parent guaranty or COFR, and (ii) entitled to receive reimbursement from TLLP for any incremental costs or expenses incurred by it or a Tesoro Party in connection with the posting of a COFR for a TLLP Facility.
