(i) The Units are to be sold by the Manager on a daily basis or otherwise as shall be agreed to by the Partnership and the Manager on any day that (A) is a single trading day, which shall mean any trading day on the NYSE, (B) the Partnership has instructed the Manager by telephone (confirmed promptly by electronic mail) to make such sales and (C) the Partnership has satisfied its obligations under Section 6 of this Agreement. The Partnership will designate the maximum amount of the Units to be sold by the Manager daily as agreed to by the Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Unit at which such Units may be sold. Subject to the terms and conditions hereof, the Manager shall use its reasonable efforts to sell on a particular day all of the Units designated for the sale by the Partnership on such day. The gross sales price of the Units sold under this Section 3(a) shall be the market price of the Partnership’s Common Units sold by the Manager under this Section 3(a) on the NYSE at the time of sale of such Units.

(ii) The Partnership Parties acknowledge and agree that (A) there can be no assurance that the Manager will be successful in selling the Units, (B) no Manager will incur any liability or obligation to the Partnership or any other person or entity if the Manager does not sell Units for any reason other than a failure by the Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Units as required under this Agreement, and (C) no Manager shall be under any obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by the Manager and the Partnership Parties.

(iii) The Partnership shall not authorize the issuance and sale of, and the Manager shall not be obligated to use its reasonable efforts to sell, any Units not approved for sale by the Board of Directors of the General Partner (the “Board”), or an Officer of the General Partner duly authorized by the Board, and notified by such duly authorized officer to the Manager in writing. The Partnership or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend or terminate the offering of the Units for any reason and at any time; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Units sold hereunder prior to the giving of such notice.

(iv) The Manager hereby covenants and agrees not to make any sales of the Units on behalf of the Partnership, pursuant to this Section 3(a), other than (A) by means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 under the Act (such transactions are hereinafter referred to as “Continuous Offerings”) and (B) such other sales of the Units on behalf of the Partnership in its capacity as agent of the Partnership as shall be agreed by the Partnership and the Manager pursuant to a Terms Agreement.

(v) The compensation to the Manager for sales of the Units with respect to which the Manager acts as sales agent under this Agreement shall be up to 2.0% of the gross sales price of the Units sold pursuant to this Section 3(a) as described in Schedule II of this Agreement and payable as described in the succeeding subsection (vi) below. The foregoing rate of compensation shall not apply when the Manager acts as principal, in which case the Partnership may sell Units to the Manager as principal at a price agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The remaining proceeds, after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Transaction Fees”), shall constitute the net proceeds to the Partnership for such Units (the “Net Proceeds”).

(vi) The Manager acting as sales agent hereunder shall provide written confirmation (which may be by facsimile or electronic mail) to the Partnership following the close of trading on the NYSE each day in which the Units are sold under this Section 3(a) setting forth the number of the Units sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Partnership, and the compensation payable by the Partnership to the Manager with respect to such sales.

On each Settlement Date, the Units sold through a Manager for settlement on such date shall be issued and delivered by the Partnership to the Manager against payment of the aggregate gross sales proceeds less any Transaction Fees for the sale of such Units. Settlement for all such Units shall be effected by free delivery of the Units to the Manager’s account at The Depository Trust Company (“DTC”) in return for payments in same day funds delivered to the Partnership by federal funds wire transfer to the account designated by the Partnership. If the Partnership or its transfer agent (if applicable) shall default on its obligation to deliver the Units on any Settlement Date, the Partnership shall (A) indemnify and hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership and (B) pay the Manager any compensation to which it would otherwise be entitled absent such default. If a Manager acting as sales agent breaches this Agreement by failing to deliver the aggregate gross sales proceeds less any Transaction Fees to the Partnership on any Settlement Date for the Units delivered by the Partnership, the Manager will pay the Partnership interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to the Manager.

(viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k)), the Partnership shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date other than those representations and warranties made of a specific date as specified herein, but modified to incorporate the disclosures contained in the Registration Statement and the Prospectus as amended as of such date. Any obligation of a Manager to use its reasonable efforts to sell the Units on behalf of the Partnership shall be subject to the continuing accuracy of the representations and warranties of the Partnership herein (as modified in the manner described above), to the performance by the Partnership of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

(b) If the Partnership wishes to issue and sell the Units pursuant to this Agreement but other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify a Manager of the proposed terms of such Placement.

The terms set forth in a Terms Agreement will not be binding on the Partnership or the Manager unless and until the Partnership and the Manager have each executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

(c) Each sale of the Units to a Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Units to, and the purchase thereof by, the Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Units by the Manager. The commitment of the Manager to purchase the Units pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Partnership herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Units to be purchased by the Manager pursuant thereto, the price to be paid to the Partnership for such Units, any provisions relating to rights of, and default by, underwriters acting together with the Manager in the reoffering of the Units, and the time and date (each such time and date being referred to herein as a “Time of Delivery”) and place of delivery of and payment for such Units. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by the Manager.

(d) Under no circumstances shall the number and aggregate amount of the Units sold pursuant to this Agreement and any Terms Agreement exceed (i) the aggregate amount set forth in Section 1, (ii) the number of Common Units available for issuance under the currently effective Registration Statement or (iii) the number and aggregate amount of the Units authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized Officer, and notified to the Manager in writing.

(e) If either party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Units, it shall promptly notify the other party and sales of the Units under this Agreement and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(f) Subject to the limitations set forth herein and as may be mutually agreed upon by the Partnership and the Manager, no sales of Units shall take place, and the Partnership shall not request the sale of any Units that would be sold, and the Manager shall not be obligated to sell, during any period in which the Partnership is in possession of material non-public information.

The Partnership will use its reasonable best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable best efforts to have such amendment or new registration statement declared effective as soon as practicable.

7. Indemnification and Contribution.

(a) The Partnership Parties, jointly and severally, agree to indemnify and hold harmless the Manager, the directors, officers, employees and agents of the Manager, each affiliate of the Manager who has participated in the distribution of the Units, each broker dealer affiliate of the Manager and each other affiliate of the Manager with the meaning of Rule 405 under the Act and each person who controls the Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or in any amendment thereof, or in the Base Prospectus, the Prospectus Supplement, the Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto 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 the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Partnership Parties 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 such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Partnership by the Manager specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Partnership Parties may otherwise have.

(b) The Manager agrees to indemnify and hold harmless the Partnership Parties, each of the General Partner’s directors, each of the officers of the Partnership Parties who sign the Registration Statement, and each person who controls the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Partnership Parties to the Manager, but only with reference to written information relating to a Manager furnished to the Partnership by or on behalf of the Manager specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Manager may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding

in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Partnership Parties, jointly and severally, and the Manager agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Partnership Parties and the Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties on the one hand and by the Manager on the other from the offering of the Units; provided, however, that in no case shall the Manager be responsible for any amount in excess of the compensation to the Manager for sales of the Units hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Partnership Parties, jointly and severally, and the Manager shall severally contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership Parties on the one hand and of the Manager on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Partnership Parties shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, and benefits received by the Manager shall be deemed to be equal to the total compensation received by the Manager with respect to the Units purchased under this Agreement, in each case as determined by this Agreement or any applicable Terms Agreement. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Partnership on the one hand or the Manager on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Partnership Parties and the Manager agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls a Manager within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of a Manager shall have the same rights to contribution as the Manager, and each person who controls the Partnership Parties within the meaning of either the Act or the Exchange Act, each officer of either of the Partnership Parties who shall have signed the Registration Statement and each director of the General Partner shall have the same rights to contribution as the Partnership Parties, subject in each case to the applicable terms and conditions of this paragraph (d).

8. Termination.

(a) The Partnership Parties shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement, with respect to the Manager, relating to the solicitation of offers to purchase the Units in their sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) if Units have been sold through the Manager for the Partnership, then Section 4(u) shall remain in full force and effect, (ii) with respect to any pending sale, through the Manager for the Partnership, the obligations of the Partnership Parties, including in respect of compensation of the Manager, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Sections 2, 5, 7, 9, 10, 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) The Manager shall have the right, by giving written notice as hereinafter specified, to terminate its own obligations under the provisions of this Agreement relating to the solicitation of offers to purchase the Units in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that the provisions of Sections 2, 5, 7, 9, 10, 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

(c) This Agreement shall remain in full force and effect until the earlier of (i) its termination pursuant to Section 8(a) above or otherwise by mutual agreement of all of the parties and (ii) the termination of the obligations of the Manager pursuant to Section 8(b) above; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Sections 2, 5, 7 and 9 shall remain in full force and effect.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Manager or the Partnership Parties, as the case may be. If such termination shall occur prior to the Settlement Date or Time of Delivery for any sale of the Units, such sale shall settle in accordance with the provisions of Section 3(a)(vii) of this Agreement.

(e) In the case of any purchase of Units by the Manager pursuant to a Terms Agreement, the obligations of the Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of the Manager, by notice given to the Partnership prior to the Time of Delivery relating to such Units, if at any time prior to such delivery and payment (i) trading in the Partnership’s Common Units shall have been suspended by the Commission or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Manager, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Prospectus (exclusive of any amendment or supplement thereto).

9. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Partnership Parties or the General Partner’s officers, on behalf of the Partnership Parties, as the case may be, and of the Manager set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Manager or the Partnership Parties or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Units.

11. Successors.

12. No Fiduciary Duty.

Furthermore, the Partnership Parties agree that the Partnership is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Manager has advised or is currently advising the Partnership on related or other matters). The Partnership Parties agree that the Partnership will not claim that the Manager has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Partnership, in connection with such transaction or the process leading thereto.

Ladies and Gentleman:

Tesoro Logistics LP, a Delaware limited partnership (the “Partnership”) and Tesoro Logistics GP, LLC, a Delaware limited liability company and the sole general partner of the Partnership (the “General Partner”), propose, subject to the terms and conditions stated herein and in the Equity Distribution Agreement, dated June 25, 2014 (the “Equity Distribution Agreement”), among the Partnership, the General Partner and Citigroup Global Markets Inc., that the Partnership issue and sell to [ ] (the “Manager”), the securities specified in Schedule I hereto (the “Purchased Units”)[, and, solely for the purpose of covering over-allotments, to grant to Citigroup Global Markets Inc. the option to purchase the additional securities specified in Schedule I hereto (the “Additional Units”)].

[The Manager shall have the right to purchase from the Partnership all or a portion of the Additional Units as may be necessary to cover over-allotments made in connection with the offering of the Purchased Units, at the same purchase price per common unit to be paid by the Manager to the Partnership for the Purchased Units. This option may be exercised by the Manager at any time (but not more than once) on or before the thirtieth day following the date hereof, by written notice to the Partnership. Such notice shall set forth the aggregate number of Additional Units as to which the option is being exercised, and the date and time when the Additional Units are to be delivered (such date and time being herein referred to as the “Option Closing Date”); provided, however, that the Option Closing Date shall not be earlier than the Time of Delivery (as set forth in Schedule I hereto) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. Payment of the purchase price for the Additional Units shall be made at the Option Closing Date in the same manner and at the same office as the payment for the Purchased Units.]

Each of the provisions of the Equity Distribution Agreement not specifically related to the solicitation by the Manager, as agent of the Partnership, of offers to purchase securities is incorporated herein by reference in its entirety, and shall be deemed to be part of this Terms Agreement to the same extent as if such provisions had been set forth in full herein. Each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Terms Agreement, the Time of Delivery [and any Option Closing Date], except that each representation and warranty in Section 2 of the Equity Distribution Agreement which makes reference to the Prospectus (as therein defined) shall be deemed to be a representation and warranty as of the date of the Equity Distribution Agreement in relation to the Prospectus, and also a representation and warranty as of the date of this Terms Agreement, the Time of Delivery [and any Option Closing Date] in relation to the Prospectus as amended and supplemented to relate to the Purchased Units.

An amendment to the Registration Statement (as defined in the Equity Distribution Agreement), or a supplement to the Prospectus, as the case may be, relating to the Purchased Units [and the Additional Units], in the form heretofore delivered to the Manager is now proposed to be filed with the Securities and Exchange Commission.

Subject to the terms and conditions set forth herein and in the Equity Distribution Agreement which are incorporated herein by reference, the Partnership agrees to issue and sell to the Manager and the latter agrees to purchase from the Partnership the number of Purchased Units [and Additional Units] at the time and place and at the purchase price set forth in Schedule I hereto.
