Certain terms used herein are defined in Section 18 hereof.

3. Sale and Delivery of Offered Units.

(a) Sale of Offered Units by Managers, as Sales Agents. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership agrees to issue and sell Offered Units from time to time through the Managers, acting as sales agents, and each Manager agrees to use its reasonable efforts to sell, as sales agent for the Partnership, the Offered Units on the following terms.

(i) The Offered Units are to be sold by one of the Managers on a daily basis or otherwise as shall be agreed to by the Partnership and such Manager on any day that (A) is a trading day for the New York Stock Exchange (“NYSE”) (other than a day on which the NYSE is scheduled to close prior to its regular weekday closing time) (each, a “Trading Day”), (B) the Partnership, through any of the individuals listed on Schedule I hereto (the “Authorized Representatives”), has instructed such 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 Offered Units to be sold by such Manager daily as agreed to by such 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 Offered Unit at which such Offered Unit may be sold. Subject to the terms and conditions hereof, such Manager shall use its reasonable efforts consistent with normal sales and trading practices to sell on a particular day all of the Offered Units designated for sale by the Partnership on such day. The gross sales price of the Offered Units sold under this Section 3(a) shall be the market price for Offered Units of the Partnership’s Common Units sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Offered Units. The Partnership shall submit instructions to sell Offered Units to only one Manager, if any, on any single Trading Day.

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

(iii) The Partnership shall not authorize the issuance and sale of, and the relevant Manager shall not be obligated to use its reasonable efforts to sell, any Offered Units at a price lower than the minimum price therefor designated from time to time by the Board, a duly authorized committee thereof, or any individual to whom such authority has been duly and properly delegated by the Board, and notified to such Manager in writing. The Partnership or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend the sales of Offered Units hereunder 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 Offered Units sold hereunder prior to the giving of such notice.

(iv) Each Manager hereby covenants and agrees not to make any sales of the Offered 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 of the Securities Act (such transactions are hereinafter referred to as “Continuous Offerings”) and (B) such other sales of the Offered Units on behalf of the Partnership in its capacity as agent of the Partnership as shall be agreed by the Partnership and such Manager pursuant to a Terms Agreement.

(v) The compensation to the relevant Manager for sales of the Offered Units with respect to which such Manager acts as sales agent under this Agreement shall be up to 2.0% of the gross sales price of the Offered Units sold pursuant to this Section 3(a) and payable as described in the succeeding subsection (vi). The foregoing rate

of compensation shall not apply when such Manager acts as principal, in which case the Partnership may sell Offered Units to such Manager as principal at a price mutually 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 (before expenses) to the Partnership for such Offered Units (the “Net Proceeds”).

(vi) Each Manager 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 Offered Units are sold under this Section 3(a) setting forth the number of the Offered 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 such Manager with respect to such sales. Such compensation may be deducted from the gross proceeds from the sale of such Offering Units or shall be set forth and invoiced in periodic statements from such Manager to the Partnership, with payment to be made by the Partnership promptly after its receipt thereof.

(vii) Settlement for sales of the Offered Units pursuant to this Section 3(a) will occur on the third Business Day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Offered Units sold through a Manager for settlement on such date shall be issued and delivered by the Partnership to such Manager against payment of the aggregate gross sales proceeds less compensation payable by the Partnership to such Manager and any Transaction Fees for the sale of such Offered Units. Settlement for all such Offered Units shall be effected by free delivery of the Offered Units to such Manager’s account at The Depository Trust Company (“DTC”) in return for payments in same day funds delivered to the account designated by the Partnership. If the Partnership or its transfer agent (if applicable) shall default on its obligation to deliver the Offered Units on any Settlement Date, the Partnership Parties shall (A) indemnify and hold such Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership and (B) pay such Manager any commission to which it would otherwise be entitled absent such default. If such Manager breaches this Agreement by failing to deliver the aggregate gross sales proceeds less compensation payable by the Partnership to such Manager and any Transaction Fees to the Partnership on any Settlement Date for the Offered Units delivered by the Partnership, such Manager will pay the Partnership interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to such Manager.

(viii) At each Applicable Time, Settlement Date, Representation Date (as defined in Section 4(j)) and date on which the Partnership shall be obligated to file a Quarterly Report on Form 10-Q or Annual Report on Form 10-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, modified as necessary to relate to the Registration Statement and the Prospectus as amended as of such date and to reflect such necessary modifications as are not material and approved by a Manager in advance. Any obligation of any Manager to use its reasonable efforts to sell the Offered

Units on behalf of the Partnership shall be subject to the continuing accuracy of the representations and warranties of the Partnership herein, 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) Sale of Offered Units by a Manager, as Principal. If the Partnership wishes to issue and sell the Offered 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. If such Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Partnership wishes to accept amended terms, such Manager and the Partnership will enter into a Terms Agreement setting forth the terms of such Placement. The terms set forth in a Terms Agreement will not be binding on the Partnership or such Manager unless and until the Partnership and such 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) Terms Agreement. Each sale of the Offered 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 Offered Units to, and the purchase thereof by, such Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Offered Units by such Manager. The commitment of such Manager to purchase the Offered Units pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Offered Units to be purchased by such Manager pursuant thereto, the price to be paid to the Partnership for such Offered Units, any provisions relating to rights of, and default by, underwriters acting together with such Manager in the reoffering of the Offered 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 Offered 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 such Manager.

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

(e) Regulation M Exemption. 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 Offered Units, it shall promptly notify the other party and sales of the Offered 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) Prohibition on Sales During Blackout Periods. Notwithstanding any other provision of this Agreement, the Partnership shall not request the sale of any Offered Units that would be sold, and the Managers shall not be obligated to sell, during any period in which the Partnership is, or could be deemed to be, in possession of material non-public information; provided that, unless otherwise agreed between the Partnership and the Managers, for purposes of this Section 3(f) such period shall be deemed to end on the date on which the Partnership’s next subsequent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is filed with the Commission.

(a) Filing Amendment or Supplement.

The Partnership has prepared the Prospectus, in a form approved by the Managers, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be prepared in a form approved by the Managers, and will file such supplement with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed thereby and will provide evidence satisfactory to the Managers of such timely filing. The Partnership will promptly advise the Managers (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (ii) when, during any period when the delivery of a prospectus (whether physically or through compliance with Rule 172 or any similar rule) is required under the Securities Act in connection with the offering or sale of the Offered Units, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Offered Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its reasonable 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 efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) Material Misstatements or Omissions in Prospectus. During any period when the delivery of a prospectus relating to the Offered Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) under the Securities Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made at such time, not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus in order to comply with the Securities Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, the Partnership promptly will (i) notify the Managers of any such event, (ii) prepare and file with the Commission, subject to the first sentence of Section 4(a), an amendment or supplement or new registration statement, or such other document under the Exchange Act, which will correct such statement or omission or effect such compliance, (iii) use its reasonable efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to such Manager in such quantities as such Manager may reasonably request.

(c) Reports to Security Holders and Managers.

(d) Signed Copies of Registration Statement. The Partnership will furnish to each Manager and counsel for such Manager, without charge, signed copies of the Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by such Manager or dealer may be required by the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of the Prospectus and any supplement thereto as such Manager may reasonably request. The Partnership will pay the expenses of printing or other production of all documents relating to the offering.

(e) Qualifications. The Partnership will arrange, if necessary, for the qualification of the Offered Units for sale under the laws of such jurisdictions as the Managers may designate and will maintain such qualifications in effect so long as required for the distribution of the Offered Units; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Offered Units, in any jurisdiction where it is not now so subject.

(f) No Issuer Free Writing Prospectus. Each of the Partnership and the Managers agrees that it has not made and will not make any offer relating to the Offered Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433.

(g) Limitations on Sale of Common Units. At any time that sales of Offered Units have been made but not settled or at any time that the Partnership has outstanding with any Manager instructions to sell Offered Units but such instructions have not been fulfilled or cancelled, the Partnership will not, directly or indirectly, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership, any affiliate of the Partnership or any person in privity with the Partnership or any affiliate of the Partnership (other than, in each instance, any director, officer or employee of NuStar GP or NuStar Holdings in his or her individual capacity)), including the filing (or participation in the filing) of a registration statement with the Commission (other than a shelf registration statement under Rule 415 under the Securities Act or a registration statement on Form S-8) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units; or publicly announce an intention to effect any such transaction without (i) giving such Manager at least three full Business Days’ prior written notice specifying the nature of the proposed transaction and the date of such proposed transaction and (ii) such Manager suspending action under this Agreement for such period of time requested by the Partnership or as deemed appropriate by such Manager in light of the proposed transaction; provided, however, that the Partnership may (1) issue and sell Common Units pursuant to this Agreement or any Terms Agreement, (2) grant, issue and sell Common Units, phantom units, restricted units, performance units, options and other unit-based awards by the Partnership to employees and directors of NuStar GP under the NuStar GP, LLC Fourth Amended and Restated 2000 Long-Term Incentive Plan, the NuStar GP, LLC Amended and Restated 2003 Employee Unit Incentive Plan and the NuStar GP, LLC 2002 Unit Option Plan, (3) issue Common Units issuable upon the conversion of securities or the exercise of warrants outstanding at the Execution Time and (4) issue Common Units in connection with any acquisition, provided that, in connection with such issuance, the seller(s) agrees in writing to be bound by the provisions of this Section 4(g).

(j) Certificates. Upon commencement of the offering of the Offered Units under this Agreement (and upon the recommencement of the offering of the Offered Units under this Agreement following the termination of a suspension of sales hereunder), and each time that (i) the Registration Statement or the Prospectus is amended or supplemented (other than an

amendment or supplement effected by the filing with the Commission of any document incorporated by reference therein which shall be subject to the provisions of subclauses (ii) and (iv) below), (ii) the Partnership files an Annual Report on Form 10-K, a Quarterly Report on Form 10-Q or a Current Report on Form 8-K containing financial information (other than information “furnished”) (or any amendment thereto), (iii) the Offered Units are delivered to any Manager as principal at the Time of Delivery pursuant to a Terms Agreement and such delivery is required by the Terms Agreement, or (iv) otherwise as any Manager may reasonably request (such commencement or recommencement date and each such date referred to in (i), (ii), (iii) and (iv) above, a “Representation Date”), the Partnership shall furnish or cause to be furnished to the Managers a certificate dated and delivered within three Trading Days (but in any event prior to any date on which sales of Offered Units are subsequently requested pursuant to this Agreement) of such commencement or recommencement, effectiveness of such amendment, the date of filing with the Commission of such report, supplement or other document, the time of the signing of the applicable Terms Agreement, or promptly upon request, as the case may be, in form satisfactory to the Managers (or, in the case of subclause (iii) above, the relevant Manager party to the Terms Agreement) to the effect that the statements contained in the certificate referred to in Section 6(e) of this Agreement which were last furnished to the Managers are true and correct at the time of such commencement or recommencement, amendment, supplement, filing, or delivery, as the case may be, as though made at and as of such time (except that such statements shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to such time and to reflect such necessary modifications as are not material and approved by the Managers in advance) or, in lieu of such certificate, a certificate of the same tenor as the certificate referred to in said Section 6(e), modified as necessary to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such certificate.

Notwithstanding the foregoing, if the Partnership subsequently decides to sell Offered Units following a Representation Date when the Partnership relied on such waiver and did not provide the Managers with a certificate under this Section 4(j), then before the Partnership delivers an instruction pursuant to Section 3(a) or any Manager sells Offered Units, the Partnership shall provide such Manager with a certificate, in the form provided in this Section 4(j), dated the date of such instruction.

(m) Letter of Independent Accountants. Upon commencement of the offering of the Offered Units under this Agreement (and upon the recommencement of the offering of the Offered Units under this Agreement following the termination of a suspension of sales hereunder), and within three Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate pursuant to Section 6(e) for which no waiver is applicable (but in any event prior to any date on which sales of Offered Units are subsequently requested pursuant to this Agreement), the Partnership shall cause KPMG LLP (and any other independent accountant whose report is included or incorporated by reference in the Prospectus) (the “Accountants”), or other independent accountants satisfactory to the Managers forthwith, to furnish the Managers or, in the case of subclause (ii) above, the relevant Manager party to the Terms Agreement, a letter, dated the date of commencement or recommencement, effectiveness of such amendment, the date of filing of such supplement or other document with the Commission, or the Time of Delivery, as the case may be, in form satisfactory to the Managers or, in the case of subclause (ii) above, the relevant Manager party to the Terms Agreement, of the same tenor as the letter referred to in Section 6(f) of this Agreement but modified to relate to the Registration Statement and the Prospectus, as amended and supplemented to the date of such letter.

The Partnership shall cooperate timely with any reasonable due diligence request from or review conducted by the Managers or its agents from time to time in connection with the transactions contemplated by this Agreement, including, without limitation, providing information and available documents and access to appropriate corporate officers and the Partnership’s agents during regular business hours and at the Partnership’s principal offices, and timely furnishing or causing to be furnished such certificates, letters and opinions from the Partnership, its officers and its agents, as the Managers may reasonably request.

(r) Failure of Certain Conditions. If to the knowledge of the Partnership, the conditions set forth in Section 6(a), 6(g)(ii) or 6(h) shall not be true and correct on the applicable Settlement Date, the Partnership will offer to any person who has agreed to purchase Offered Units from the Partnership as the result of an offer to purchase solicited by any Manager the right to refuse to purchase and pay for such Offered Units.

(s) Acceptance of Offer to Purchase. Each acceptance by the Partnership of an offer to purchase the Offered Units hereunder, and each execution and delivery by the Partnership of a Terms Agreement, shall be deemed to be an affirmation to the Managers that the representations and warranties of the Partnership contained in or made pursuant to this Agreement are true and correct as of the date of such acceptance or of such Terms Agreement as though made at and as of such date (except for those representations and warranties which speak as of a specific date or time), and an undertaking that such representations and warranties will be true and correct as of the Settlement Date for the Offered Units relating to such acceptance or as of the Time of Delivery relating to such sale, as the case may be, as though made at and as of such date (except that such representations and warranties shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented relating to such Offered Units).

(t) Listing of Common Units. The Partnership will use its commercially reasonable efforts to cause the Offered Units to be listed for trading on the NYSE and to maintain such listing.

(u) Delivery of Prospectus. During any period when the delivery of a prospectus relating to the Offered Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) under the Securities Act, the Partnership will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the regulations thereunder.

(v) DTC. The Partnership shall cooperate with the Managers and use its reasonable efforts to permit the Offered Units to be eligible for clearance and settlement through the facilities of DTC.

(a) The Prospectus, and any supplement thereto, required by Rule 424 to be filed with the Commission have been filed in the manner and within the time period required by Rule 424(b) with respect to any sale of Offered Units; and no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use shall have been issued and no proceedings for that purpose shall have been instituted or threatened.

(d) The Managers shall have received from Xxxxx Xxxxx L.L.P., counsel for the Managers, on every date specified in Section 4(l) of this Agreement, such opinion or opinions, dated as of such date and addressed to the Managers, with respect to the issuance and sale of the Offered Units, the Registration Statement, the Prospectus (together with any supplement thereto) and other related matters as the Managers may reasonably require, and the Partnership shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(e) The Partnership shall have furnished or caused to be furnished to the Managers, on every date specified in Section 4(j) of this Agreement, a certificate of the Partnership, signed by (1) either the President and Chief Executive Officer or the Senior Vice President, General Counsel—Corporate & Commercial Law and Corporate Secretary, in each case of NuStar GP, and (2) either the Executive Vice President and Chief Financial Officer or the Senior Vice President and Controller, in each case of NuStar GP, dated as of such date, to the effect that the signers of such certificate have carefully examined the Registration Statement and the Prospectus and any supplements or amendments thereto and this Agreement and that:

(i) The representations, warranties and agreements of the Partnership Parties in Section 2 are true and correct on and as of such date, modified as necessary to relate to the Registration Statement and the Prospectus as amended as of such date and to reflect such necessary modifications as are approved by the Managers in advance; and that each of the Partnership Parties has complied with all of its respective agreements contained herein and satisfied all of the respective conditions on its part to be performed or satisfied hereunder at or prior to such date;

(ii) No stop order suspending the effectiveness of the Registration Statement has been issued; and no proceedings or examination for that purpose have been instituted or, to the knowledge of such officers, threatened; and the Commission has not notified the Partnership of any objection to the use of the form of the Registration Statement or any post-effective amendment thereto; and

(iii) They have carefully examined the Registration Statement and the Prospectus, and nothing has come to their attention that would lead them to believe that, (A) (1) the Registration Statement, as of the Effective Date, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (2) the Prospectus, as of its date and on the date of such certificate, included or includes any untrue statement of a material fact and omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances in which they were made, not misleading or (B) since the date of the most recent financial statements included in the Prospectus, an event has occurred that should have been set forth in a supplement or amendment to the Registration Statement or the Prospectus that has not been so set forth.

(f) The Partnership shall have requested and caused the Accountants to have furnished to the Managers, on every date specified in Section 4(m) hereof and to the extent requested by the Managers in connection with any offering of the Offered Units, letters (which may refer to letters previously delivered to the Managers), dated as of such date, in form and substance satisfactory to the Managers, (i) confirming that they are independent accountants within the meaning of the Securities Act and the Exchange Act and the respective applicable rules and regulations adopted by the Commission and the PCAOB and (ii) stating, as of the date of such letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Prospectus, as of a date not more than five days prior to the date of such letter), the conclusions and findings of such firm with respect to the financial information required to be incorporated by reference in the Prospectus and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings; provided that Section 6(g) shall be the only provision of this Agreement relating to the letter required to be delivered with respect to Axeon and this Section 6(f) shall not govern the delivery thereof.

(h) Since the respective dates as of which information is disclosed in the Registration Statement and the Prospectus, except as otherwise stated therein, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (f) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Partnership and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Prospectus the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Managers, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Offered Units as contemplated by the Registration Statement and the Prospectus.

(i) There shall not have been any decrease in the rating of any of the Partnership’s debt securities by any “nationally recognized statistical rating organization” (as that term is used in Section 3(a)(62) of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

7. Indemnification and Contribution.

(a) Each of the Partnership Parties, jointly and severally, agrees to indemnify and hold harmless each Manager, the directors, officers, employees and agents of each Manager and each person, if any, who controls each Manager within the meaning of either the Securities Act or 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 Securities 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 for the registration of the Offered Units as originally filed or in any amendment thereof, or in the Base Prospectus, the Prospectus Supplement, 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 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 no Partnership Party will

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 Managers specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Partnership Parties may otherwise have.

(b) Each Manager, severally and not jointly, agrees to indemnify and hold harmless each of the Partnership Parties, their respective directors, managers, employees and officers and each person, if any, who controls any of the Partnership Parties within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Partnership Parties to such Manager, but only with reference to written information relating to such Manager furnished to the Partnership by such Manager specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability that such 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: (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(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, each of the Partnership and the Managers 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 and the Managers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and by the Managers on the other from the offering of the Offered Units; provided, however, that in no case shall a Manager be responsible for any amount in excess of the underwriting discount or commission, as the case may be, applicable to the Offered Units purchased by such Manager hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, each of the Partnership and the Managers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership on the one hand and of the Managers 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 shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Managers shall be deemed to be equal to the total underwriting discounts and commissions, 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 Managers 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. Each of the Partnership Parties and the Managers 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 Securities 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 Securities Act or the Exchange Act and each director, officer, employee and agent of any Manager shall have the same rights to contribution as the Managers, and each person who controls the Partnership within the meaning of either the Securities Act or the Exchange Act, each officer of NuStar GP who shall have signed the Registration Statement and each director of NuStar GP shall have the same rights to contribution as the Partnership, subject in each case to the applicable terms and conditions of this paragraph (d).

8. Termination.

(a) The Partnership shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Offered Units in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) if Offered Units have been sold through any Manager for the Partnership Parties, then Section 4(s) shall remain in full force and effect, (ii) with respect to any pending sale, through any Manager for the Partnership Parties, the

obligations of the Partnership Parties, including in respect of compensation of the Managers, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Sections 5, 7, 9, 10, 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) Each 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 Offered Units in its sole discretion at any time. Any such termination shall have no effect on the obligations of any other Manager under this Agreement and shall be without liability of any party to any other party except that the provisions of Sections 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 its termination pursuant to Section 8(a) above or the termination of all Managers’ obligations pursuant to Section 8(b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Sections 5, 7 and 9 of this Agreement 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 any Manager or the Partnership, as the case may be. If such termination shall occur prior to the Settlement Date or Time of Delivery for any sale of the Offered 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 Offered Units by any Manager pursuant to a Terms Agreement, the obligations of such Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of such Manager, by notice given to the Partnership prior to the Time of Delivery relating to such Offered 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 the NYSE 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 such Manager, impractical or inadvisable to proceed with the offering or delivery of the Offered Units as contemplated by the Prospectus.

9. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Partnership Parties or their officers and of each Manager set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by the Managers or the Partnership 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 Offered Units.

Page 11

Prospectus or any of the Incorporated Documents, and are not so summarized and (c) furthermore, no facts have come to our attention that have led us to believe that (i) the Registration Statement, at the time it became effective and as of its most recent effective date, contained an untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) the Prospectus (including the Incorporated Documents), as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, it being understood that we did not participate in the preparation of the Incorporated Documents and that we express no opinion, statement or belief in this letter with respect to (i) the historical financial statements and related schedules, including the notes and schedules thereto and the auditor’s reports thereon, (ii) any other financial or accounting data, included or incorporated or deemed incorporated by reference in, or excluded from, the Registration Statement or the Prospectus, and (iii) representations and warranties and other statements of fact included in the exhibits to the Registration Statement or the Incorporated Documents.

Furthermore, we advise you that according to the effectiveness order of the SEC (regarding the Registration Statement) appearing in the SEC’s Electronic Data Gathering, Analysis, and Retrieval system, the Registration Statement was declared effective under the Securities Act on June 2, 2015. In addition, based solely on our review of the information made available by the SEC at xxxx://xxx.xxx.xxx/xxxxxxxxxx/xxxxxxxxxx.xxxxx, we confirm that the SEC has not issued any stop order suspending the effectiveness of the Registration Statement.

References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Equity Distribution Agreement, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references (including without limitation those appearing in paragraphs 13 and 14 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust, laws, rules or regulations.

Our opinions expressed herein are subject to the following additional assumptions and qualifications:

(3) subject to the effect of applicable law relating to fiduciary duties.

(v) We express no opinion as to the validity, effect or enforceability of any provisions:

(1) purporting to establish evidentiary standards or limitations periods for suits or proceedings to enforce such documents or otherwise, to establish certain determinations (including determinations of contracting parties and judgments of courts) as conclusive or conclusive absent manifest error, to commit the same to the discretion of any Person or permit any Person to act in its sole judgment or to waive rights to notice;

(x) The opinion set forth in paragraph 16 above with respect to United States federal income tax consequences is based upon our interpretations of current United States federal income tax law, including court authority and existing final and temporary U.S. Treasury regulations, which are subject to change both prospectively and retroactively, and upon the assumptions and qualifications discussed herein.
