14. CONFIDENTIAL INFORMATION

     (a) Obligations. Each Party shall use reasonable efforts to retain the other Parties’ Confidential Information in confidence and not disclose the same to any third party nor use the same, except as authorized by the disclosing Party in writing or as expressly permitted in this Section 14. Each Party further agrees to take the same care with the other Party’s Confidential Information as it does with its own, but in no event less than a reasonable degree of care. Excepted from these obligations of confidence and non-use is that information which:

          (i) is available, or becomes available, to the general public without fault of the receiving Party;

          (ii) was in the possession of the receiving Party on a non-confidential basis prior to receipt of the same from the disclosing Party (it being understood, for the avoidance of doubt, that this exception shall not apply to information of the Logistics Group that was in the possession of the Tesoro Group or any of its Affiliates as a result of their ownership or operation of the Logistics Assets prior to the Commencement Date);

          (iii) is obtained by the receiving Party without an obligation of confidence from a third party who is rightfully in possession of such information and, to the receiving Party’s knowledge, is under no obligation of confidentiality to the disclosing Party; or

          (iv) is independently developed by the receiving Party without reference to or use of the disclosing Party’s Confidential Information.

For the purpose of this Section 14, a specific item of Confidential Information shall not be deemed to be within the foregoing exceptions merely because it is embraced by, or underlies, more general information in the public domain or in the possession of the receiving Party.

     (b) Required Disclosure. Notwithstanding Section 14(a) above, if the receiving Party becomes legally compelled to disclose the Confidential Information by a court, Governmental Authority or Applicable Law, or is required to disclose by the listing standards of the New York Stock Exchange, any of the disclosing Party’s Confidential Information, the receiving Party shall promptly advise the disclosing Party of such requirement to disclose Confidential Information as soon as the receiving Party becomes aware that such a requirement to disclose might become effective, in order that, where possible, the disclosing Party may seek a protective order or such other remedy as the disclosing Party may consider appropriate in the circumstances. The receiving Party shall disclose only that portion of the disclosing Party’s Confidential Information that it is required to disclose and shall cooperate with the disclosing Party in allowing the disclosing Party to obtain such protective order or other relief.

     (c) Return of Information. Upon written request by the disclosing Party, all of the disclosing Party’s Confidential Information in whatever form shall be returned to the disclosing Party upon

termination of this Agreement or destroyed with destruction certified by the receiving Party, without the receiving Party retaining copies thereof except that one copy of all such Confidential Information may be retained by a Party’s legal department solely to the extent that such Party is required to keep a copy of such Confidential Information pursuant to Applicable Law and the receiving Party shall be entitled to retain any Confidential Information in the electronic form or stored on automatic computer back-up archiving systems during the period such backup or archived materials are retained under such Party’s customary procedures and policies; provided, however, that any Confidential Information retained by the receiving Party shall be maintained subject to confidentiality pursuant to the terms of this Section 14, and such archived or back-up Confidential Information shall not be accessed except as required by Applicable Law.

     (d) Receiving Party Personnel. The receiving Party will limit access to the Confidential Information of the disclosing Party to those of its employees, attorneys and contractors that have a need to know such information in order for the receiving Party to exercise or perform its rights and obligations under this Agreement (the “Receiving Party Personnel”). The Receiving Party Personnel who have access to any Confidential Information of the disclosing Party will be made aware of the confidentiality provision of this Agreement, and will be required to abide by the terms thereof. Any third party contractors that are given access to Confidential Information of a disclosing Party pursuant to the terms hereof shall be required to sign a written agreement pursuant to which such Receiving Party Personnel agree to be bound by the provisions of this Agreement, which written agreement will expressly state that it is enforceable against such Receiving Party Personnel by the disclosing Party.

     (e) Survival. The obligation of confidentiality under this Section 14 shall survive the termination of this Agreement for a period of two (2) years.

15. MISCELLANEOUS

     (a) Modification; Waiver. This Agreement may be terminated, amended or modified only by a written instrument executed by the Parties. Any of the terms and conditions of this Agreement may be waived in writing at any time by the Party entitled to the benefits thereof. 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.

     (b) Entire Agreement. This Agreement, together with the Schedules, 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.

     (c) Governing Law; Jurisdiction. This Agreement shall be governed by the laws of the State of Texas without giving effect to its conflict of laws principles. Each Party hereby irrevocably submits to the exclusive jurisdiction of any federal court of competent jurisdiction situated in the United States District Court for the Western District of Texas, San Antonio Division, or if such federal court declines to exercise or does not have jurisdiction, in the district court of Bexar County, Texas. The Parties expressly and irrevocably submit to the jurisdiction of said Courts and irrevocably waive any objection which they may now or hereafter have to the laying of venue of any action, suit or proceeding arising out of or relating to this Agreement brought in such Courts, irrevocably waive any claim that any such action, suit or proceeding brought in any such Court has been brought in an inconvenient forum and further irrevocably waive the right to object, with respect to such claim, action, suit or proceeding brought in any such Court, that such Court does not have jurisdiction over such Party. The Parties hereby irrevocably

consent to the service of process by registered mail, postage prepaid, or by personal service within or without the State of Texas. Nothing contained herein shall affect the right to serve process in any manner permitted by law.

     (d) Counterparts. This Agreement may be executed in one or more counterparts (including by facsimile or portable document format (pdf)) for the convenience of the Parties hereto, each of which counterparts will be deemed an original, but all of which counterparts together will constitute one and the same agreement.

     (e) 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.

     (f) 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.

     (g) 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.

     (h) Schedules. Each of the Schedules attached hereto and referred to herein is hereby incorporated in and made a part of this Agreement as if set forth in full herein.

[Signatures of the Parties follow on the next page.]

     IN WITNESS WHEREOF, the Parties hereto have duly executed this Agreement as of the date first written above.
