fully and unconditionally guaranteed by Phillips 66

UNDERWRITING AGREEMENT

1. Introductory. Phillips 66 Company, a Delaware corporation (the “Company”), and Phillips 66, a Delaware corporation (the “Guarantor”), propose that the Company will issue and sell from time to time certain of its unsecured debt securities that will be fully and unconditionally guaranteed by the Guarantor registered under the registration statement referred to in Section 2(a) (such securities, including the guarantee relating thereto by the Guarantor (the “Guarantee”), being hereinafter called the “Registered Securities”). The Registered Securities will be issued under the Indenture, dated as of May 5, 2022 (the “Indenture”), among the Company, the Guarantor and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), in one or more series, which series may vary as to interest rates, maturities, redemption provisions, selling prices and other terms, with all such terms for any particular series of the Registered Securities being determined at the time of sale. Particular series of the Registered Securities will be sold pursuant to a Terms Agreement referred to in Section 3, for resale in accordance with terms of offering determined at the time of sale.

The Registered Securities involved in any such offering are hereinafter referred to as the “Offered Securities”. The firm or firms which agree to purchase the Offered Securities, as set forth in a Terms Agreement referred to in Section 3, are hereinafter referred to as the “Underwriters” of such securities, and the representative or representatives of the Underwriters, if any, specified in a Terms Agreement referred to in Section 3 are hereinafter referred to as the “Representatives”; provided, however, that if the Terms Agreement does not specify any representative of the Underwriters, the term “Representatives”, as used in this Agreement (other than in Sections 2(b), 2(c), 2(f) and 6 and the second sentence of Section 3), shall mean the Underwriters.

The Offered Securities are being issued and sold in connection with the merger (the “Merger”) of Dynamo Merger Sub LLC, a Delaware limited liability company (the “Merger Sub”), with and into DCP Midstream, LP, a Delaware limited partnership (the “Partnership”), with the Partnership surviving the Merger, pursuant to a Agreement and Plan of Merger, dated as of January 5, 2023 (as may be amended and supplemented from time to time, the “Merger Agreement”), by and among the Guarantor, Phillips 66 Project Development Inc., the Merger Sub, the Partnership, DCP Midstream GP, LP and DCP Midstream GP, LLC. Subject to the terms of the Indenture, the Company will be required to redeem the Offered Securities of each series then outstanding at a special mandatory redemption price equal to 101% of the principal amount of the Offered Securities to be redeemed plus accrued and unpaid interest to the date of redemption upon the first occurrence of any of the following events: (a) the closing of the Merger does not occur on or prior to 11:59 p.m., New York City Time, on December 31, 2023 (the

“Special Mandatory Redemption End Date”), (b) the Merger Agreement is terminated prior to the Special Mandatory Redemption End Date without the closing of the Merger or (c) the Company notifies the trustee of the Offered Securities in writing that in the Guarantor’s reasonable judgment the Merger will not be consummated on or prior to the Special Mandatory Redemption End Date. The Company intends to use the net proceeds of the Offered Securities, together with borrowings under its $1.5 billion delayed draw term loan credit agreement, by and among the Company, the Guarantor, the lenders party thereto and Mizuho Bank, Ltd., as administrative agent, and cash on hand, to finance the merger consideration payable in the Merger. Prior to closing of the Merger, the Company may use the net proceeds of the Offered Securities for general corporate purposes.

(e) (i) At the earliest time after the filing of the Registration Statement that the Company or the Guarantor or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of any Offered Securities and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), neither the Company nor the Guarantor was or is an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer or that it is not necessary that the Guarantor be considered an Ineligible Issuer.

(h) Neither the Company nor the Guarantor is (i) in violation of its certificate of incorporation or by-laws, (ii) in default under any agreement or instrument to which the Company or the Guarantor is a party or by which the Company or the Guarantor is bound or to which any of the properties of the Company or the Guarantor is subject, or (iii) in violation of any law, ordinance, governmental rule or regulation or court decree to which it may be subject, which default or violation in the case of clause (ii) or (iii) could reasonably be expected to have a Material Adverse Effect.

(i) Each of the Company and the Guarantor is duly qualified to do business as a foreign corporation in good standing in all jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse Effect.

(j) All of the issued and outstanding shares of capital stock of the Company have been duly authorized and are validly issued, fully paid and non-assessable. Except as set forth in the Final Prospectus, all of the issued and outstanding shares of capital stock of the Company are owned directly or indirectly by the Guarantor, free and clear of all liens, encumbrances, equities or claims.

(k) The consolidated financial statements, together with the notes related thereto, of the Guarantor and its consolidated subsidiaries included or incorporated by reference in the Registration Statement, the Disclosure Package and the Final Prospectus, present fairly the financial position of the Guarantor as of the dates shown and the results of the Guarantor’s operations and cash flows for the periods shown, and such financial statements comply in all material respects as to form with the accounting requirements of the Act and have been prepared in conformity with generally accepted accounting principles in the United States (“GAAP”) applied on a consistent basis throughout the periods involved, except as otherwise noted therein or as may be expressly stated in the related notes thereto. No other financial statements are required to be included in the Registration Statement. The interactive data in eXtensible Business Reporting Language furnished with the Exchange Act filings incorporated by reference in the Registration Statement, the Disclosure Package and the Final Prospectus fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto. All non-GAAP financial information included in the Registration Statement, if any, complies with the requirements of Item 10 of Regulation S-K under the Act.

(m) Neither the Guarantor nor any of its consolidated subsidiaries, nor to the knowledge of the Company or the Guarantor, any agent, director, officer, employee or other person associated with or acting on behalf of the Guarantor or its consolidated subsidiaries has, since May 1, 2012, (i) used any funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to

3. Purchase and Offering of Offered Securities. The obligation of the Underwriters to purchase the Offered Securities will be evidenced by an agreement or exchange of other written communications (“Terms Agreement”) at the time the Company determines to sell the Offered Securities. The Terms Agreement will incorporate by reference the provisions of this Agreement, except as otherwise provided therein, and will specify the firm or firms which will be Underwriters, the names of any Representatives, the principal amount of the Offered Securities to be purchased by each Underwriter, the commission or fee to be paid to the Underwriters and the terms of the Offered Securities not already specified in the Indenture, including, but not limited to, interest rate, maturity, any redemption provisions and any sinking fund requirements. The Terms Agreement will also specify the time and date of delivery and payment (such time and date, or such other time not later than seven full business days thereafter as the Representatives and the Company agree as the time for payment and delivery, being herein and in the Terms Agreement referred to as the “Closing Date”), the place of delivery and payment and any details of the terms of offering that should be reflected in the prospectus supplement relating to the offering of the Offered Securities. For purposes of Rule 15c6-1 under the Exchange Act, the Closing Date (if later than the otherwise applicable settlement date) shall be the date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. The obligations of the Underwriters to purchase the Offered Securities will be several and not joint. It is understood that the Underwriters propose to offer the Offered Securities for sale as set forth in the Final Prospectus.

If the Terms Agreement specifies “Book-Entry Only” settlement or otherwise states that the provisions of this paragraph shall apply, the Company will deliver against payment of the cash purchase price the Offered Securities in the form of one or more permanent global securities in definitive form (the “Global Securities”) deposited with the Trustee as custodian for The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., as nominee for DTC. The Global Securities will be made available for inspection by the Representatives not later than 5:00 pm, New York City time, on the business day prior to the Closing Date. Interests in any permanent global securities will be held only in book-entry form through DTC, except in the limited circumstances described in the Final Prospectus. Payment for the Offered Securities shall be made by the Underwriters in Federal (same day) funds by official check or checks or wire transfer to an account previously designated by the Company at a bank acceptable to the Representatives, in each case drawn to the order of the Company at the place of payment specified in the Terms Agreement on the Closing Date, against delivery to the Trustee as custodian for DTC of the Global Securities representing all of the Offered Securities.

4. Certain Agreements of the Company. The Company agrees with the several Underwriters that the Company will furnish to counsel for the Underwriters one signed copy (but not an original) of the registration statement relating to the Registered Securities, including all exhibits, in the form it became effective and of all amendments thereto and that, in connection with each offering of Offered Securities:

(a) The Company will cause the Final Prospectus to be filed with the Commission pursuant to and in accordance with Rule 424(b)(2) (or, if applicable and if consented to by the Representatives, subparagraph (5)) not later than the second business day following the execution and delivery of the Terms Agreement.

(b) During any time when a prospectus relating to the Offered Securities is required to be delivered under the Act in connection with sales by any Underwriter or dealer (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Act), the Company will advise the Representatives promptly of any proposal to amend or supplement the Registration Statement or the Final Prospectus and will afford the Representatives a reasonable opportunity to comment on any such proposed amendment or supplement; and the Company will also advise the Representatives promptly of the filing of any such amendment or supplement and of the institution by the Commission of any stop order proceedings or any notice from the Commission objecting to its use in respect of the Registration Statement or of any part thereof and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(c) The Company will prepare a final term sheet, containing solely a description of the Offered Securities, in a form approved by the Representatives, and will cause such term sheet to be filed pursuant to Rule 433(d) under the Act within the time required by such Rule.

(d) If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will promptly notify the Representatives, so that any use of the Disclosure Package may cease until it is amended or supplemented, and will promptly prepare and cause to be filed with the Commission, at its own expense, an amendment or supplement that will correct such statement or omission or an amendment that will effect such compliance.

(e) If, at any time when a prospectus relating to the Offered Securities is required to be delivered under the Act in connection with sales by any Underwriter or dealer (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Act), any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or would omit to state a material fact necessary

to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Final Prospectus to comply with the Act, the Company will promptly notify the Representatives of such event and will promptly prepare and cause to be filed with the Commission, at its own expense, an amendment or supplement that will correct such statement or omission or an amendment that will effect such compliance. The terms “supplement” and “amendment” as used in this Agreement include, without limitation, all documents filed by the Company and the Guarantor with the Commission subsequent to the date of the Final Prospectus that are deemed to be incorporated by reference in the Final Prospectus. Neither the Representatives’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 5 hereof.

(f) As soon as practicable, but not later than 16 months, after the date of each Terms Agreement, the Company will make generally available to security holders of the Company an earning statement of the Guarantor covering a period of at least 12 months beginning after the latest of (i) the effective date of the registration statement relating to the Registered Securities, (ii) the effective date of the most recent post-effective amendment to the Registration Statement to become effective prior to the date of such Terms Agreement and (iii) the date of the Guarantor’s most recent Annual Report on Form 10-K filed with the Commission prior to the date of such Terms Agreement, which will satisfy the provisions of Section 11(a) of the Act.

(g) The Company will furnish to the Representatives copies of the Registration Statement, including all exhibits, and during any time when a prospectus relating to the Offered Securities is required to be delivered under the Act in connection with sales by any Underwriter or dealer (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Act), the Base Prospectus, any related Preliminary Final Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Representatives reasonably request.

(h) The Company will use its commercially reasonable efforts to arrange for the qualification of the Offered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution; provided, however, that neither the Company nor the Guarantor will be required in connection therewith to register or qualify as a foreign corporation where it would not otherwise be so qualified or to execute a general consent to service of process in any jurisdiction or subject itself to taxation in any jurisdiction where it would not otherwise be so subject. The Company will promptly advise the Representatives of the receipt by it or the Guarantor of any notification with respect to the suspension of the qualification of the Offered Securities for offer and sale in any such jurisdiction or the initiation or threatening of any proceeding for such purpose.

(i) During the period of five years after the date of any Terms Agreement, the Company will furnish or make available to the Representatives and, upon request, to each of the other Underwriters, if any, as soon as practicable after the end of each fiscal year, a copy of the Guarantor’s annual report to stockholders for such year; and the Company will furnish or make available to the Representatives (i) as soon as available, a copy of each report (other than a report on Form 11-K) and any definitive proxy statement of the Guarantor filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company or the Guarantor as the Representatives may reasonably request in connection with the offering of the Offered Securities.

(j) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay all costs and expenses incident to the performance of its obligations under the Terms Agreement (including the provisions of this Agreement); any filing fees or other expenses (including reasonable fees and disbursements of counsel) in connection with qualification of the Offered Securities for sale and determination of their eligibility for investment under the laws of such jurisdictions as the Representatives may designate in accordance with Section 4(h) and the printing of memoranda relating thereto; any fees charged by investment rating agencies for the rating of the Offered Securities; any costs incident to the issuance and delivery of the Offered Securities (including printing and engraving costs) and any necessary issue, transfer or other stamp taxes in that connection; any applicable filing fee incident to, and the reasonable fees and disbursements of counsel for the Underwriters in connection with, the preparation of any Blue Sky memorandum and review by the Financial Industry Regulatory Authority, Inc. of the Offered Securities; any travel expenses of the Company’s or the Guarantor’s officers and employees and any other expenses of the Company or the Guarantor in connection with attending or hosting meetings with prospective purchasers of the Offered Securities; and for expenses incurred in preparing, printing and distributing the Final Prospectus, any preliminary prospectuses, any preliminary prospectus supplements or any other amendments or supplements to the Final Prospectus to the Underwriters. Except as provided in Section 4(j), Section 6 and Section 8 hereof, the Underwriters shall pay their own expenses, including the fees and disbursements of counsel.

(k) Each of the Company and the Guarantor agrees that, unless the Company has obtained or will obtain, as the case may be, the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company and the Guarantor that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Offered Securities 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 Company with the Commission or retained by the Company under Rule 433, other than the final term sheet prepared and filed pursuant to Section 4(c) hereto; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses, if any, included in Schedule B to the applicable Terms Agreement. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus”. Each of the Company and the Guarantor agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and recordkeeping.

(l) Each of the Company and the Guarantor consents to the use by any Underwriter of a free writing prospectus that (a) is not an Issuer Free Writing Prospectus, and (b) contains only (i) information describing the preliminary terms of the Offered Securities or their offering, (ii) information required or permitted by Rule 134 under the Act that is not “issuer information” as defined in Rule 433 or (iii) information that describes the final terms of the Offered Securities or their offering and that is included in the final term sheet prepared and filed pursuant to Section 4(c) hereto.

(m) The Company will not, and will cause the Guarantor not to, offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Act relating to any United States dollar-denominated debt securities issued or guaranteed by the Company or the Guarantor and having a maturity of more than one year from the date of issue, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the Representatives for a period beginning at the time of execution of the Terms Agreement and ending the number of days after the Closing Date specified under “Blackout” in the Terms Agreement.

(v) the Registration Statement has become effective under the Act, the Final Prospectus was filed with the Commission pursuant to the subparagraph of Rule 424(b) specified in such opinion on the date specified therein and the final term sheet contemplated by Section 4(c) hereto has been filed with the Commission within the applicable time period prescribed therefor by Rule 433, and, to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or any part thereof or any notice from the Commission objecting to its use has been issued and no proceedings for that purpose have been instituted or are pending or threatened under the Act, and the Registration Statement, as of its latest effective date, the Registration Statement and the Final Prospectus, as of the Execution Time, (in each case, other than the financial statements and schedules, the notes thereto

(f) The Representatives, on behalf of the Underwriters, shall have received from Cravath, Swaine & Moore LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to the incorporation of the Company and the Guarantor, the validity of the Offered Securities and the Guarantee, the Registration Statement, the Final Prospectus, the Disclosure Package and other related matters as the Representatives may reasonably require, and the Company and the Guarantor shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

If any condition specified in this Section 5 shall not have been fulfilled when and as required to be fulfilled, the Terms Agreement and this Agreement may be terminated by the Representatives by notice to the Company at any time at or prior to the Closing Date, and such termination shall be without liability of any party to any other party except as provided in Section 4(j) and except that Sections 2, 4, 6, 8, 15 and 16 hereof shall survive any such termination and remain in full force and effect.

6. Indemnification and Contribution. (a) The Company and the Guarantor will jointly and severally indemnify and hold harmless each Underwriter, its partners, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act 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 any material fact contained in the Registration Statement, the Base Prospectus, any Preliminary Final Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 4(c) hereto, or any amendment 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 will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company 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 an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives, if any, specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in the Terms Agreement.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company and the Guarantor, their respective directors and officers and each person, if any, who controls the Company or the Guarantor within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or the Guarantor may become subject, under the Act 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 any material fact contained in the Registration Statement, the Base Prospectus, any Preliminary Final Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 4(c) hereto, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein 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 Company by such Underwriter through the Representatives, if any, specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company or the Guarantor in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in the Terms Agreement.

(c) Promptly after receipt by an indemnified party under this Section 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 subsection (a) or (b) above, notify in writing the indemnifying party of the commencement thereof; but the omission so to notify in writing the indemnifying party (i) will not relieve it from liability under subsection (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 relieve it from any liability which it may have to any indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or

threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantor, on the one hand, and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting fees paid to (including any underwriting discounts and commissions received by) the Underwriters. The relative fault 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 Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to the partners, directors, officers and each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company or the Guarantor, to each officer of the Company or the Guarantor who has signed the Registration Statement and to each person, if any, who controls the Company or the Guarantor within the meaning of the Act.

7. Default of Underwriters. If any Underwriter or Underwriters shall default in its or their obligations to purchase Offered Securities under the Terms Agreement and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments under the Terms Agreement (including the provisions of this Agreement), to purchase the Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the Representatives and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, the Terms Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Guarantor, except as provided in Section 8. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

8. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or the Guarantor or their respective officers and of the several Underwriters set forth in or made pursuant to the Terms Agreement (including the provisions of this Agreement) will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or the Company, the Guarantor or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the Terms Agreement is terminated pursuant to Section 7 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 4 and the respective obligations of the Company and the Underwriters pursuant to Section 6 shall remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of the Terms Agreement pursuant to Section 7 or the occurrence of any event specified in clause (iii), (iv) or (v) of Section 5(c), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

9. No Fiduciary Duty. The Company hereby acknowledges and agrees that (i) the purchase and sale of any Offered Securities pursuant to this Agreement and the applicable Terms Agreement is an arm’s-length commercial transaction between the Company and the Guarantor, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (ii) the Underwriters are acting as principal and not as an agent or fiduciary of the Company or the Guarantor and (iii) the Company’s engagement of the Underwriters in connection with any offering and the process leading up to the offering of any Offered Securities is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with any offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company or the Guarantor on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company or the Guarantor, in connection with such offering or the process leading thereto.

10. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or sent by facsimile and confirmed to them at their address furnished to the Company in writing for the purpose of communications hereunder or, if sent to the Company or the Guarantor, will be mailed, delivered or sent by facsimile and confirmed to it at Phillips 66, 2331 CityWest Boulevard, Houston, Texas 77042, Facsimile: (918) 977-9634, Attention: Treasurer, or such other address as the Company may notify the Underwriters.

11. Successors. The Terms Agreement (including the provisions of this Agreement) will inure to the benefit of and be binding upon the Company, the Guarantor and such Underwriters as are identified in the Terms Agreement and their respective successors and the officers and directors and controlling persons referred to in Section 6, and no other person will have any right or obligation hereunder.

12. Representation of Underwriters. Any Representatives will act for the several Underwriters in connection with the financing described in the Terms Agreement, and any action under such Terms Agreement (including the provisions of this Agreement) taken by the Representatives will be binding upon all the Underwriters.

13. Counterparts. The Terms Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same agreement. Any electronic signature hereof shall be of the same legal effect, validity or enforceability as a manually executed signature, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

14. Effect of Headings. This Article and Section headings herein are for convenience only and shall not affect the meaning or interpretation of this Agreement.

15. Applicable Law. This Agreement and the Terms Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of laws.

Each of the Company and the Guarantor hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to the Terms Agreement (including the provisions of this Agreement) or the transactions contemplated thereby.

16. Waiver of Jury Trial. Each of the Company and the Guarantor and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

17. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.
