Ladies and Gentlemen:

Tesoro Logistics LP, a limited partnership organized under the laws of Delaware (the “Partnership”), and Tesoro Logistics Finance Corp., a Delaware corporation (together with the Partnership, the “Issuers”), propose to issue and sell to the several underwriters named in Schedule I hereto (the “Underwriters”), for whom RBC Capital Markets, LLC is acting as Representative (in such capacity, the “Representative”), $750,000,000 aggregate principal amount of their 5.25% Senior Notes due 2025 (the “Notes”), which will be unconditionally guaranteed on a senior unsecured basis as to principal, premium, if any, and interest (the “Guarantees”) by the subsidiaries of the Partnership named in Schedule II hereto (each, a “Guarantor” and, collectively, the “Guarantors”). The Underwriters, acting severally and not jointly, propose to purchase the principal amount of Notes set forth opposite their respective names in Schedule I hereto. The Notes will (i) have terms and provisions which are summarized in the Disclosure Package as of the Applicable Time and the Final Prospectus dated the date hereof (each as defined below) and (ii) be issued pursuant to an indenture (the “Indenture”), to be dated as of December 2, 2016 among the Issuers, the Guarantors and U.S. Bank National Association, as Trustee (the “Trustee”). This Underwriting Agreement (this “Agreement”) is to confirm the agreement concerning the purchase of the Notes from the Issuers by the Underwriters.

In connection with the offer and sale of the Notes, the Issuers and the Guarantors have prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-214826), which contains a preliminary prospectus to be used in connection with the public offering and sale of the Notes. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, at the time it became effective under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A, 430B or 430C under the Securities Act (the “Rule 430 Information”), is called the “Registration Statement”. The term “Preliminary Prospectus” means the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information. The term “Final Prospectus” shall mean the prospectus relating to the Notes in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with the confirmation and sales of the Notes. Any reference herein to the Registration Statement, the Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or Final Prospectus as the case may be; any reference to any amendment or supplement to the Registration Statement, the Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include any documents filed after the date of such Registration Statement, the Preliminary Prospectus or Final Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), and incorporated by reference in such Registration Statement, the Preliminary

Prospectus or Final Prospectus, as the case may be. For purposes of this Agreement, all references to the Registration Statement, the Preliminary Prospectus, the Final Prospectus or any amendment or supplement to any of the foregoing shall be deemed to refer to the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”) or its Interactive Data Electronic Applications system (“IDEA”).

The term “Disclosure Package” shall mean (i) the Preliminary Prospectus and (ii) any “free writing prospectus” as defined in Rule 405 of the Securities Act identified in Schedule III hereto, which shall include the term sheet prepared pursuant to Section 4(f) hereto (the “Pricing Term Sheet”), which were available to purchasers of Notes at or prior to the time when sales of Notes were first made (the “Applicable Time”).

Copies of the Preliminary Prospectus have been, and copies of the Disclosure Package and the Final Prospectus have been or will be, made available or delivered by the Issuers to the Underwriters pursuant to the terms of this Agreement. Each of the Issuers hereby confirms that it has authorized the use of the Preliminary Prospectus, the Disclosure Package and the Final Prospectus in connection with the offering and resale of the Notes by the Underwriters in accordance with Section 3 hereof.

This Agreement, the Indenture and the Notes are hereinafter sometimes referred to collectively as the “Operative Documents”.

Underwriter or such other person in connection with investigating or defending against any such loss, claim, damage, liability or action; provided, however, that the Issuers and the Guarantors will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Pricing Disclosure Package or the Final Prospectus (or, in each case, any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Issuers by any Underwriter through the Representative specifically for use therein as set forth in Section 11 hereof.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless each Issuer and each Guarantor and their respective affiliates, directors, officers and each person, if any, who controls any of the Issuers or the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Issuers, the Guarantors, any such affiliates, directors or officers or such controlling person may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement for the registration of the Notes as originally filed or in any amendment thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make statements therein not misleading or (ii) any untrue statement of a material fact contained in any Preliminary Prospectus, the Disclosure Package, the Final Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Issuers by the Underwriters through the Representative specifically for use therein as set forth in Section 11 hereof and, subject to the limitation set forth immediately preceding this clause, will reimburse as incurred, any legal or other expenses reasonably incurred by the Issuers or the Guarantors or any such affiliates, directors or officers or such controlling person in connection with investigating, or defending against any such loss, claim, damage, liability or action in respect thereof.

(c) Promptly after receipt by any person to whom indemnity may be available under this Section 7 (the “indemnified party”) of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against any person from whom indemnity may be sought under this Section 7 (the “indemnifying party”), notify such indemnifying party in writing of the commencement thereof; but the failure so to notify such indemnifying party will not relieve such indemnifying party from (i) any liability which it may have under this Section 7 to the extent it is not materially prejudiced by such failure or (ii) any other liability which it may have to such indemnified party. In case any such action is brought against any indemnified party, and such indemnified party notifies the relevant indemnifying party of the commencement thereof, such indemnifying party will be entitled to participate therein and, to the extent that it may wish, to assume the defense thereof, jointly with any other indemnifying party similarly notified; provided, however, that if the named parties in any such action (including impleaded parties) include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded, based on advice of outside counsel, that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party or that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from an indemnifying party to an indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel

appointed to defend such action, such indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) such indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the reasonable expenses of more than one separate counsel (in addition to one local counsel in each applicable jurisdiction) for all indemnified persons in any one action or separate but substantially similar actions) or (ii) such indemnifying party does not promptly retain counsel reasonably satisfactory to such indemnified party or (iii) such indemnifying party has authorized the employment of counsel for such indemnified party at the expense of the indemnifying party. After such notice from an indemnifying party to an indemnified party, such indemnifying party will not be liable for the costs and expenses for any settlement of such action effected by such indemnified party without the written consent of such indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not the indemnified party or any other person that may be entitled to indemnification hereunder is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of the indemnified party and such other persons from all liability arising out of such claim, action, suit or proceeding and does not contain any statement as to or finding of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) (i) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 7 is unavailable or insufficient, for any reason, to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (including, without limitation, any legal or other expenses incurred in connection with defending or investigating any action or claim) (or actions in respect thereof) (“Losses”), the Issuers and the Guarantors, on the one hand, and the Underwriters, on the other, in order to provide for just and equitable contribution, agree to contribute to the amount paid or payable by such indemnified party as a result of such Losses to which the Issuers and the Guarantors, on the one hand, and the Underwriters, on the other, may be subject, in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantors, on the one hand, and the Underwriters, on the other, from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is unavailable for any reason, not only such relative benefits but also the relative fault of the Issuers and the Guarantors, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions or alleged statements or omissions that resulted in such Losses. The relative benefits received by the Issuers and the Guarantors, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses, but, for the avoidance of doubt, net of the Underwriters’ discounts and commissions) received by the Issuers bear to the total discounts and commissions received by the Underwriters from the Issuers in connection with the purchase of the Notes hereunder as set forth in the Final Prospectus or this Agreement. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers, the Guarantors or the Underwriters, the parties’ intent, relative knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. The Issuers, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or by any other method of allocation (even if the Underwriters were treated as one entity for such purpose) that does not take into account the equitable considerations referred to above. Notwithstanding any other provision of this paragraph (d), no Underwriter shall be obligated to make contributions hereunder that in the aggregate exceed the total purchase discounts and commissions received by such Underwriter from the Issuers in connection with the purchase of the Notes hereunder, and no person

guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ respective obligations to contribute hereunder are several in proportion to their respective obligations to purchase Notes as set forth on Schedule I hereto and not joint. For purposes of this paragraph (d), each affiliate, director or officer of any Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each other person listed in Section 7(a) hereof shall have the same rights to contribution as such Underwriter, and each affiliate, director or officer of any Issuer or any Guarantor and each person, if any, who controls any Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Issuers and the Guarantors.

(e) The obligations of the Issuers and the Guarantors under this Section 7 shall be in addition to any obligations or liabilities which the Issuers and the Guarantors may otherwise have and the obligations of the respective Underwriters under this Section 7 shall be in addition to any obligations or liabilities which the Underwriters may otherwise have.

8. Survival. The respective representations, warranties, agreements, covenants, indemnities, rights of contribution and other statements of the Issuers, the Guarantors, their respective officers, and the several Underwriters set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Underwriters, the Issuers, the Guarantors, their respective affiliates, officers or directors or any controlling person referred to in Section 7 hereof and (ii) delivery of and payment for the Notes. The respective agreements, covenants, indemnities, rights of contribution and other statements set forth in Sections 5, 7, 8, 11, 12, 13, 14 and 15 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement.

9. Termination. (a) This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Issuers, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading in securities generally on the New York Stock Exchange, the NASDAQ Stock Market or in the over-the-counter market shall have been suspended or minimum prices shall have been established on any such exchange or market; (ii) trading in any securities of any Issuer on any exchange or in the over-the-counter market, shall have been suspended or minimum prices shall have been established on any such exchange or market; (iii) there has been a material disruption in commercial banking or securities settlement, payment or clearance services in the United States; (iv) a banking moratorium shall have been declared by New York or United States authorities or (v) there shall have been (A) an outbreak or significant escalation of hostilities between the United States and any foreign power, (B) an outbreak or significant escalation of any other insurrection or armed conflict involving the United States, (C) the occurrence of any other calamity or crisis or (D) any material and adverse change in general economic, political or financial conditions which has an effect on the U.S. financial markets or the international financial markets that, in the case of any event described in this clause (v), in the sole judgment of the Representative, makes it impracticable or inadvisable to proceed with the offer, sale and delivery of the Notes on the terms and in the manner contemplated by this Agreement, the Disclosure Package or the Final Prospectus.

(b) Termination of this Agreement pursuant to this Section 9 shall be without liability of any party to any other party except as provided in Sections 5(b) hereof.

10. Defaulting Underwriters. If, on the Closing Date, any Underwriter defaults in the performance of its obligations under this Agreement, the non-defaulting Underwriters shall be obligated to purchase the Notes that such defaulting Underwriter or Underwriters agreed but failed to purchase on

the Closing Date (the “Remaining Notes”) in the respective proportions that the principal amount of the Notes set opposite the name of each non-defaulting Underwriter in Schedule I hereto bears to the total number of the Notes set opposite the names of all the non-defaulting Underwriters in Schedule I hereto; provided, however, that the non-defaulting Underwriters shall not be obligated to purchase any of the Notes on the Closing Date if the total amount of Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the total amount of Notes to be purchased on the Closing Date, and no non-defaulting Underwriter shall be obligated to purchase more than 110% of the amount of Notes that it agreed to purchase on the Closing Date pursuant to this Agreement. If the foregoing maximums are exceeded, the non-defaulting Underwriters, or those other purchasers satisfactory to the Underwriters and the Issuers who so agree, shall have the right, but not the obligation, to purchase, in such proportion as may be agreed upon among them, all the Remaining Notes. If the non-defaulting Underwriters or other Underwriters satisfactory to the Underwriters and the Issuers do not elect to purchase the Remaining Notes, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Issuers, except that the Issuers will continue to be liable for the payment of expenses to the extent set forth herein.

Nothing contained in this Agreement shall relieve a defaulting Underwriter of any liability it may have to the Issuers, the Guarantors or a non-defaulting Underwriter for damages caused by its default. If other purchasers are obligated or agree to purchase the Notes of a defaulting or withdrawing Underwriter, the Issuers or the Representative may postpone the Closing Date for up to five full business days in order to effect any changes in the Transaction Documents or in any other document or arrangement that, in the opinion of Counsel for the Issuers or Counsel for the Underwriters, may be necessary.

11. Information Supplied by Underwriters. The names of each Underwriter appearing on the front and back covers and in the first, seventh and eighth paragraphs under the caption “Underwriting” of the Preliminary Prospectus and the Final Prospectus and the statements in the second paragraph (second sentence) and fourth paragraph (second sentence) under the caption “Underwriting” in the Preliminary Prospectus and the Final Prospectus, constitute the only information furnished by the Underwriters to the Issuers for the purposes of Sections 1(a) and 7 hereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Issuers, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

13. Successors. This Agreement shall inure to the benefit of and shall be binding upon the several Underwriters, the Issuers and the Guarantors and their respective successors and legal representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained, this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of the several Underwriters, the Issuers and the

Guarantors and their respective successors and legal representatives, and for the benefit of no other person, except that (i) the indemnities of the Issuers contained in Section 7 of this Agreement shall also be for the benefit of any affiliate, director or officer of an Underwriter and any person or persons who control any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and (ii) the indemnities of the Underwriters contained in Section 7 of this Agreement shall also be for the benefit of the affiliates, directors and officers of the Issuers and the Guarantors, and any person or persons who control the Issuers or the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act.
