Ladies and Gentlemen:

Occidental Petroleum Corporation, a Delaware corporation (the “Company”), confirms its agreement with the underwriters listed onSchedule A (collectively the “Underwriters,” which term also includes any underwriter substituted as hereinafter provided in Section 11) with respect to the issue and sale by the Company of (i) $750,000,000 aggregate principal amount of the Company’s 3.000% Senior Notes due 2027 (the “2027 Notes”), and (ii) $750,000,000 aggregate principal amount of the Company’s 4.100% Senior Notes due 2047 (the “2047 Notes” and, together with the 2027 Notes, the “Notes”) and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts of Notes set forth opposite their names onSchedule A. The Notes are to be issued pursuant to an indenture, dated as of August 18, 2011 (the “Indenture,” which term, for purposes of this Agreement, includes the Officers’ Certificate with respect to the Notes delivered pursuant to Section 301 of the Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). Citigroup Global Markets Inc., J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC will be the representatives of the Underwriters (the “Representatives”).

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement onForm S-3 (No. 333-205047) for the registration of debt securities, including the Notes, under the Securities Act of 1933, as amended (the “1933 Act”), and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Such

registration statement became effective upon filing with the Commission pursuant to Rule 462(e) of the 1933 Act Regulations, and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “1939 Act”). Such registration statement (as amended by any subsequent post-effective amendments thereto) and the prospectus dated June 18, 2015 (the “Base Prospectus”), together with the final prospectus supplement dated November 2, 2016 (the “Final Prospectus Supplement”) relating to the Notes, including, in each case, all Incorporated Documents (as hereinafter defined) and, solely in the case of any such registration statement, the information that is deemed pursuant to Rule 430B of the 1933 Act Regulations to be part of such registration statement (“Rule 430B Information”), are referred to herein as the “Registration Statement” and the “Prospectus,” respectively, except that, if any revised prospectus or any revised or additional prospectus supplement filed by the Company is provided to the Underwriters by the Company for use in connection with the offering of the Notes (including for delivery upon request of purchasers of Notes pursuant to Rule 173 of the 1933 Act Regulations), the term “Prospectus” will refer to such revised prospectus or any such revised or additional prospectus supplement, as the case may be, from and after the time it is first provided to the Underwriters for such use. As used herein, the term “preliminary prospectus” means any prospectus supplement filed by the Company relating to the Notes that is captioned “Subject to Completion” or “preliminary prospectus supplement” or that has a similar caption, together with the Base Prospectus, including all Incorporated Documents, it being understood that all references herein to a “preliminary prospectus” include, without limitation, the Statutory Prospectus (as defined below). Any reference herein to the Registration Statement, any preliminary prospectus or the Prospectus is deemed to refer to and include the documents, financial statements and schedules incorporated, or deemed to be incorporated, by reference therein (other than information in such documents, financial statements and schedules that is deemed not to be filed) pursuant to Item 12 of Form S-3 under the 1933 Act, and any reference to any amendment or supplement to the Registration Statement, any preliminary prospectus or the Prospectus is deemed to refer to and include any documents, financial statements and schedules filed by the Company with the Commission under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and so incorporated, or deemed to be incorporated, by reference (other than information in such documents, financial statements and schedules that is deemed not to be filed) (such incorporated documents, financial statements and schedules being herein called the “Incorporated Documents”). Notwithstanding the foregoing, for purposes of this Agreement any prospectus supplement prepared or filed with respect to an offering pursuant to the Registration Statement of any securities other than the Notes will not be deemed to have supplemented any preliminary prospectus or the Prospectus and the information therein will not be deemed Rule 430B Information. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or any preliminary prospectus, or to any Issuer Free Writing Prospectus, Issuer General Use Free Writing Prospectus or Issuer Limited Use Free Writing Prospectus (as such terms are hereinafter defined) or to any amendment or supplement to any of the foregoing are deemed to include any copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

The Company understands that the Underwriters propose to make a public offering of the Notes as soon as the Underwriters deem advisable after this Agreement has been executed and delivered.

Such notification from the Company to the Underwriters shall direct the Underwriters to suspend use of such Issuer Free Writing Prospectus until the Company shall have provided the Underwriters an amended or supplemented Issuer Free Writing Prospectus as contemplated above, in which case the Underwriters will cease using such Issuer Free Writing Prospectus until such time as the Company shall have provided them such amended or supplemented Issuer Free Writing Prospectus.

The foregoing covenants in this Section 4(e) do not apply to statements or omissions in the Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of the Underwriters through the Representatives expressly for use therein or in any Form T-1.

(f) Earnings Statements. The Company will make generally available to its security holders a consolidated earnings statement (which need not be audited) covering a period of at least twelve months commencing after the Closing Time, as soon as is reasonably practicable after the end of such period, which earnings statement will satisfy the provisions of Section 11(a) of the 1933 Act (and at the option of the Company, Rule 158 of the 1933 Act Regulations).

(g) Blue Sky Qualifications. The Company will endeavor, in cooperation with the Underwriters, to qualify the Notes for offering and sale under the applicable securities laws of such states and other jurisdictions as the Underwriters may reasonably designate (provided no registration will be required in any jurisdiction outside the United States), and will maintain such qualifications in effect for as long as may be required for the distribution of the Notes; provided, however, that the Company will promptly notify the Underwriters of any suspension of any such qualifications; and provided, further, that the Company will not be obligated to register or qualify as a foreign corporation or take any action which would subject it to general service of process in any jurisdiction where it is not now so subject.

(h) Filing of Prospectus; Preparation of Final Term Sheet.

(i) The Company will prepare a final term sheet (the “Final Term Sheet”) reflecting the final terms of the Notes, which will be substantially in the form set forth in Schedule B but may also include credit ratings information with respect to the Notes, and will file such Final Term Sheet, in a form approved by the Representatives, as an “issuer free writing prospectus” pursuant to Rule 433 prior to the close of business within two business days after the date of this Agreement.

(ii) The Company will prepare and file or transmit for filing with the Commission within the time period specified by Rule 424(b) of the 1933 Act Regulations (without reliance on Rule 424(b)(8)), the Prospectus containing the terms of the Notes and such other information as the Representatives and the Company deem appropriate.

(i) Issuer Free Writing Prospectuses. (i) The Company represents and agrees that, unless it obtains the prior consent of the Representatives (which will not be unreasonably withheld or delayed), and (ii) each Underwriter, severally and not jointly, represents and agrees that, unless it obtains the prior written consent of the Company and the Representatives (which will not be unreasonably withheld or delayed), it has not made and will not make any offer relating to the Notes that would constitute an “issuer free writing prospectus,” as defined in Rule 433, 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 pursuant to Rule 433; provided that the Company consents to the use by any Underwriter of a free writing prospectus that:

(ii) is not an “issuer free writing prospectus” as defined in Rule 433, and

(iii) contains only:

(x) information describing the preliminary terms of the Notes or their offering,

(y) information that describes the final terms of the Notes or their offering and that is included in the Final Term Sheet contemplated in Section 4(h) of this Agreement, or

(z) contains comparable bond price or similar information that (in the case of this clause (z) only) is not “issuer information,” as defined in Rule 433.

Any such free writing prospectus as to which consent has been given by the Representatives or by the Company and the Representatives, as the case may be, is referred to as a “Permitted Free Writing Prospectus.” Without limiting the effect of the prior sentence, it is agreed that each of the Final Term Sheet and any Issuer Free Writing Prospectus listed on Schedule C is a Permitted Free Writing Prospectus.

SECTION 5. Payment of Expenses.

The Company will pay all expenses incident to the performance of its obligations under this Agreement, including:

(a) The preparation and filing of the Registration Statement and all amendments thereto, the General Disclosure Package, each preliminary prospectus and the Prospectus and any amendments or supplements thereto and all Incorporated Documents;

(b) The preparation, filing and printing of this Agreement;

(d) The reasonable fees and disbursements of the Trustee and its counsel and of any calculation agent or exchange rate agent in connection with the Indenture and the Notes;

(g) The preparation, printing and delivery to the Underwriters of copies of the Indenture; and

SECTION 7. Indemnification.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, each officer and director of each Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever (including, subject to the limitations set forth in subsection 7(c), the reasonable fees and disbursements of counsel chosen by the Representatives), as incurred, insofar as such loss, liability, claim, damage or expense arises out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arises out of any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever (including, subject to the limitations set forth in subsection 7(c), the reasonable fees and disbursements of counsel chosen by the Representatives), as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever, insofar as such loss, liability, claim, damage or expense arises out of any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever (including, subject to the limitations set forth in subsection 7(c), the reasonable fees and disbursements of counsel chosen by the Representatives), as incurred, reasonably incurred in investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever, based upon any such untrue statement or omission, or any such alleged untrue statement or omission;

provided,however, that this indemnity will not apply to any loss, liability, claim, damage or expense (A) to the extent arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon the Form T-1 under the 1939 Act filed as an exhibit to the Registration Statement; or (B) as to which such Underwriter may be required to indemnify the Company pursuant to the provisions of subsection (b) of this Section 7.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection 7(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, any preliminary prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representatives expressly for use in the Registration Statement,

such preliminary prospectus, the General Disclosure Package, such Issuer Free Writing Prospectus or the Prospectus (or such amendment or supplement). The Company hereby acknowledges that the only information that the Underwriters have furnished to the Company by or on behalf of such Underwriter through the Representatives expressly for use in the Registration Statement, such preliminary prospectus, the General Disclosure Package, such Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) are: (i) the information in the third paragraph under the caption “Underwriting” in the preliminary prospectus supplement and the Final Prospectus Supplement, but solely insofar as it concerns the terms of the offering by the Underwriters; (ii) the information in the third sentence of the fifth paragraph under the caption “Underwriting” in the preliminary prospectus supplement and the Final Prospectus Supplement, but solely insofar as it concerns market making by the Underwriters; (iii) the information in the sixth paragraph and seventh paragraph under the caption “Underwriting” in the preliminary prospectus supplement and the Final Prospectus Supplement, but solely insofar as it concerns stabilization transactions by and penalty bids imposed by the Underwriters; and (iv) the information in the twelfth paragraph under the caption “Underwriting” in the preliminary prospectus supplement and the Final Prospectus Supplement.

(i) In case any action, suit or proceeding (including any governmental or regulatory investigation or proceeding) is brought against any Underwriter, any officer or director of such Underwriter or any person controlling such Underwriter, based upon the Registration Statement, any preliminary prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) and with respect to which indemnity may be sought against the Company pursuant to this Section 7, such Underwriter, officer, director or controlling person will promptly notify the Company in writing, and the Company will assume the defense thereof, including the employment of counsel reasonably satisfactory to the Representatives and payment of all expenses. Failure to give such notice will not relieve the Company from any liability under this Section 7 to the extent it is not materially prejudiced as a result thereof and in any event will not relieve it from any liability which it may have otherwise than on account of the indemnity contained in this Section 7. Any such Underwriter, any such officer or director or any such controlling person will have the right to employ separate counsel in any such action, suit or proceeding and to participate in the defense thereof, but the fees and expenses of such separate counsel will be at the expense of such Underwriter, such officer or director or such controlling person, unless (A) the employment of such counsel has been specifically authorized in writing by the Company, (B) the Company has failed to assume the defense and employ reasonably satisfactory counsel or (C) the named parties to any such action, suit or proceeding (including any impleaded parties) include such Underwriter, such officer or director or such controlling person and the Company, and such Underwriter, such officer or director or such controlling person has been advised by such counsel that there may be one or more legal defenses available to it that are different from, or additional to, those available to the Company (in which case, if such Underwriter, such officer or director or such controlling person notifies the Company in writing that it elects to employ separate counsel at the expense of the Company, the Company will not have the right to assume the defense of such action, suit or proceeding on behalf of such Underwriter, such officer

or director or such controlling person, it being understood, however, that the Company will not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to one separate firm of attorneys acting as local counsel) for all such Underwriters, all such officers and directors and all such controlling persons, which firm will be designated in writing by the Representatives, on behalf of all of such Underwriters, all such officers and directors and such controlling persons).

(ii) In case any action, suit or proceeding (including any governmental or regulatory investigation or proceeding) is brought against the Company, any of the Company’s directors or officers, or any person controlling the Company, with respect to which indemnity may be sought against any Underwriter pursuant to this Section 7, such Underwriter will have the rights and duties given to the Company by subsection 7(c)(i) with respect thereto (provided that, notwithstanding the foregoing, any authorization of the nature specified in clause (A) of subsection Section 7(c)(i) may be given only by the Representatives and copies of all notices given by the Company, any such officer or director or any such controlling person of the nature specified in such subsection 7(c)(i) will also be sent to the Representatives), and the Company, such directors and officers and any such controlling persons will have the rights and duties given to the Underwriters by subsection 7(c)(i) with respect thereto, it being understood, however, that the Underwriters will not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to one separate firm of attorneys acting as local counsel) for the Company, all such officers and directors and all such controlling persons, which firm will be designated in writing by the Company, on behalf of the Company, all such officers and directors and such controlling persons.

SECTION 8. Contribution.

In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 7 is for any reason held to be unenforceable with respect to the indemnified parties, although applicable in accordance with its terms, the Company and the Underwriters will contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and the Underwriters, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Notes 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, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages and expenses. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, will be deemed to be in the same proportions as the total net proceeds from the sale of the Notes (before deducting expenses) received by the Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, bear to the total

price to public of the Notes as set forth in the table on the cover page of the Prospectus. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, will 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 by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Notes set forth opposite their names inSchedule A, and not joint. Notwithstanding the provisions of this Section 8, no Underwriter will be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed by the public were offered to the public exceeds the amount of any damages that 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 1933 Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each officer and director of an Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act will have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act will have the same rights to contribution as the Company. Any party entitled to contribution hereunder will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 8, notify such party or parties from whom contribution may be sought (with, in the case of any notice given by the Company or any of its officers, directors or controlling persons, a copy to the Representatives), but the omission to so notify such party or parties will not relieve the party or parties from whom contribution may be sought from any obligation under this Section 8 to the extent it or they are not materially prejudiced as a result thereof and in any event will not relieve it or them from any other obligation it or they may have otherwise than under this Section 8.

SECTION 9. Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement (including, without limitation, the provisions of Sections 7 and 8), or contained in certificates signed by any officer of the Company and delivered to the Underwriters, the Representatives or counsel for the Underwriters in connection with the transactions contemplated in this Agreement, will remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer or director of any Underwriter or any controlling person of any Underwriter, or by or on behalf of the Company, and will survive delivery of and payment for any of the Notes.

SECTION 10. Termination.

(a) The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time if between the date of this Agreement and the Closing Time:

(i) there has been any material adverse change in the consolidated financial condition of the Company and its subsidiaries, taken as a whole,

(ii) there has occurred any material adverse change in the financial markets in the United States or any outbreak or escalation of hostilities or other national or international calamity or crisis, in each case set forth in this clause (ii) the effect of which, individually or in the aggregate, shall be such as to make it, in the reasonable judgment of the Representatives, impracticable to market or to enforce contracts for sale of the Notes,

(iii) trading in any securities of the Company has been suspended by the Commission or a national securities exchange in the United States, or if trading generally on the New York Stock Exchange has been suspended or settlement has been materially disrupted, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by said exchange or by order of the Commission or any other governmental authority, or if a banking moratorium has been declared by either Federal or New York authorities, or

(iv) any of Standard & Poor’s Corporation and Moody’s Investors Service, Inc. (or any of their respective successors) has publicly announced that it has (A) placed the Notes or the Company’s unsecured senior long term debt generally on what is commonly termed a “watch list” for possible downgrading or (B) downgraded the Notes or the Company’s unsecured senior long term debt generally.

(b) If this Agreement is terminated pursuant to this Section, such termination will be without liability of any party to any other party except as provided in Section 5.

SECTION 11. Default by One or More of the Underwriters.

If one or more of the Underwriters fails at the Closing Time to purchase the Notes which it or they are obligated to purchase under this Agreement (the “Defaulted Notes”), the non-defaulting Underwriters will have the right, within 24 hours thereafter, to make arrangements for one or more of such non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; provided however, that if such non-defaulting Underwriters have not completed such arrangements within such 24-hour period, then:

(a) if the aggregate principal amount of Defaulted Notes does not exceed 10% of the aggregate principal amount of the Notes, the non-defaulting Underwriters will be obligated to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the aggregate principal amount of Defaulted Notes exceeds 10% of the aggregate principal amount of the Notes, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the acknowledgements and agreements in Section 2(c), the provisions of Section 5, and the indemnity and contribution agreements set forth in Sections 7 and 8 and the provisions of Section 14 will remain in effect.

No action pursuant to this Section will relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company will have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. The term “Underwriter” as used in this Agreement will include any underwriter substituted for a defaulting Underwriter.

SECTION 12. Notices.

All notices and other communications under this Agreement must be in writing and will be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication or, in the case of an Offering Termination Notice, if given to the Company by e-mail which is not returned undeliverable.

This Agreement will inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or will be construed to give any person, firm or corporation, other than the parties hereto and their respective successors and the officers, directors and controlling persons referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provisions herein contained.

EXHIBIT A

Form of Opinion of Associate General Counsel

Except as set forth in the General Disclosure Package and the Prospectus, there is not pending or, to such counsel’s knowledge, threatened, any action, suit or proceeding against the Company or any of its subsidiaries before or by any court or governmental agency or body, which is likely (to the extent not covered by insurance) to have a material adverse effect on the consolidated financial condition of the Company and its subsidiaries, taken as a whole.

EXHIBIT A-1

EXHIBIT B

Form of Opinion of Vinson & Elkins L.L.P.

The Company is validly existing as a corporation in good standing under the laws of the State of Delaware, and each Principal Domestic Subsidiary is a corporation validly existing in good standing under the laws of its respective state of incorporation.

The Company has the requisite corporate power and authority to enter into and perform its obligations under the Underwriting Agreement and the Indenture, and to issue, sell and deliver the Notes.

The Underwriting Agreement has been duly authorized by all necessary corporate action by the Company, and executed and delivered by the Company.

The Indenture has been duly authorized by all necessary corporate action by the Company, and executed and delivered by the Company and (assuming the due authorization, execution and delivery of the Indenture by the Trustee) is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as may be subject to or limited by (A) bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors’ rights generally, (B) the applicability or effect of any fraudulent transfer, preference or similar law, (C) the effect of general principles of equity and an implied covenant of good faith and fair dealing (regardless of whether enforcement is sought in a proceeding in equity or at law), (D) the effect of general rules of contract law that limit the enforceability of provisions requiring indemnification of a party for liability for its own action or inaction to the extent the action or inaction involves gross negligence, recklessness, willful misconduct or unlawful conduct and (E) the effect of public policy or applicable law to the extent either prohibits waivers or enforcement of indemnification provisions (collectively, the “Enforceability Exceptions”).

No consent or approval of any United States federal, New York or Delaware governmental authority or regulatory body is required in connection with the issuance or sale of the Notes other than registration thereof under the 1933 Act, qualification of the Indenture under the 1939 Act, and such registrations or qualifications as may be necessary under the securities or Blue Sky laws of the various United States jurisdictions in which the Notes are to be offered or sold and the rules and regulations of the Financial Industry Regulatory Authority, Inc. The opinion expressed in this paragraph 5 is limited to those consents and approvals which, in such counsel’s experience, are normally applicable to transactions of the type contemplated by the Underwriting Agreement.

The Notes have been duly authorized by all necessary corporate action by the Company, the form and terms of the Notes have been established in conformity with the provisions of the Indenture, the Notes have been executed and delivered by the Company and when authenticated by the Trustee in accordance with the terms of the Indenture and the Officers’ Certificate (assuming the due authorization, execution and delivery of the Indenture by the Trustee) and issued to and paid for by the Underwriters as contemplated by the Underwriting Agreement, the Notes will be entitled to the benefits of the Indenture

EXHIBIT B-1

and the Officers’ Certificate and will be valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except as may be subject to or limited by the Enforceability Exceptions.

The Indenture has been qualified under the 1939 Act.

The Registration Statement has become effective under the 1933 Act. With your consent, based solely on a review of the list of stop orders contained on the Commission’s website at http://www.sec.gov/litigation/stoporders.shtml and http://www.sec.gov/litigation/admin.shtml on [ ], 2016, such counsel confirms that no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings for that purpose have been initiated by the Commission.

The execution and delivery of the Underwriting Agreement and the Securities by the Company, the issuance and sale of the Notes and the performance of the Underwriting Agreement, the Securities and the Indenture by the Company will not (A) violate the Restated Certificate of Incorporation or Bylaws of the Company, (B) violate any federal or New York statute, rule or regulation applicable to the Company or the DGCL, (C) violate any judgment, decree or order known to such counsel, after reasonable inquiry, of any court or governmental agency or authority entered into in any proceeding to which the Company or any Principal Domestic Subsidiary was or is now a party or by which it is bound (and which, solely in the case of clause (C), individually or in the aggregate, is material to the Company and its subsidiaries, taken as a whole), or (D) violate or constitute a breach of or a default (with the passage of time or otherwise) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to the agreements identified onAnnex A¹, except that (i) the opinion set forth in clause (B) of this paragraph 9 is limited to those statutes, laws or regulations in effect as of the date of this opinion which, in such counsel’s experience, are normally applicable to transactions of the type contemplated by the Underwriting Agreement and (ii) such counsel expresses no opinion as to the securities or Blue Sky laws of the various jurisdictions in which the Notes are to be offered, the rules and regulations of the Financial Industry Regulatory Authority, Inc. or the anti-fraud provisions of the federal or state securities laws.

10.

(i) The Registration Statement (other than the Incorporated Documents, which are discussed below), as of the time of effectiveness of the Registration Statement for purposes of Section 11 of the 1933 Act as such section applies to the Underwriters (the “Effective Time”), (ii) the Prospectus (other than the Incorporated Documents which are discussed below), as of the date of the Final Prospectus Supplement and (iii) each Incorporated Document when such Incorporated Document was filed, or if any such Incorporated Document was amended, when such amendment was filed (in each case other than the financial statements, schedules, other financial or accounting data, statistical data and information pertaining to oil and gas reserves, which statements,

¹	Annex A to include all material agreements.

EXHIBIT B-2

schedules, data and information are included or incorporated, or deemed to be incorporated, by reference in or omitted from the Registration Statement or the Prospectus, or the exhibits thereto, including the Form T-1), each appeared on its face to be appropriately responsive in all material respects to the applicable requirements of the 1933 Act or the 1934 Act, as the case may be, and the applicable rules and regulations promulgated thereunder, except that in each case (other than as set forth in paragraphs 11 and 12 of this opinion) such counsel assumes no responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus, or the exhibits thereto, including the Form T-1.

11.

The statements in the Statutory Prospectus and the Prospectus under the captions “Description of the Notes” and “Description of Senior Debt Securities,” insofar as they purport to summarize certain provisions of the Indenture and the Notes, are accurate in all material respects.

12.

Based on the authorities and subject to the limitations and exceptions set forth therein, the statements set forth in the preliminary prospectus supplement forming a part of the General Disclosure Package and the prospectus supplement forming a part of the Prospectus under the caption “Certain U.S. Federal Income Tax Considerations,” insofar as they purport to constitute summaries of statutes, matters of law or legal conclusions, accurately summarize the matters described therein in all material respects.

In addition, such counsel should state that it has participated in conferences with officers and other representatives of the Company, outside counsel for the Company, representatives of the independent public accountants for the Company, representatives of the Underwriters and counsel for the Underwriters, at which conferences the contents of the Registration Statement, the General Disclosure Package and the Prospectus and related matters were discussed.

Although such counsel is not passing upon, and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus (other than as set forth in paragraphs 11 and 12 above) and has not made any independent check or verification thereof, on the basis of such participation, no facts have come to such counsel’s attention that lead such counsel to believe that:

(A) the Registration Statement, as of each Effective Time, contained an 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

(B) the Prospectus, as of the date of the Underwriting Agreement or as of the date of this letter, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or

(C) the General Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of circumstances under which they were made, not misleading,

EXHIBIT B-3

except that such counsel expresses no opinion with respect to the financial statements, schedules, other financial or accounting data, statistical data and information pertaining to oil and gas reserves, which statements, schedules and data are included or incorporated, or deemed to be incorporated, by reference in the Registration Statement, the Prospectus or the General Disclosure Package, or the exhibits thereto, including the Form T-1.
