SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to each Underwriter as of the date hereof, as of the Applicable Time, and as of the Closing Date referred to in Section 2(b) hereof, and agrees with each Underwriter, as follows:

(1) Status as a Well-Known Seasoned Issuer. (A) At the respective times the Registration Statement or any amendments thereto were filed with the Commission, (B) at the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the 1934 Act or form of prospectus), (C) at any time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption of Rule 163 and (D) at the date hereof, the Company was and is a “well-known seasoned issuer” as defined in Rule 405 and is eligible to use an “automatic shelf registration statement,” as defined in Rule 405 and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on such an “automatic shelf registration statement.” The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to the use of an automatic shelf registration statement and was not and is not an “ineligible issuer” (as defined in Rule 405). Any written communication that was an offer relating to the Securities made by the Company or any person acting on its behalf (within the meaning, for this sentence only, of Rule 163(c)) prior to the filing of the Registration Statement has been filed with the Commission in accordance with Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

(2) Compliance with Registration Requirements. The Company meets the requirements for use of Form S-3 under the 1933 Act and has prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405, on Form S-3, including a related Base Prospectus, for registration under the 1933 Act of the offering and sale of the Securities. The Registration Statement and any post-effective amendments thereto became effective upon filing under the 1933 Act, and no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act, and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with.

(3) Registration Statement. The Registration Statement did not and will not, as of each effective date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided that no representation or warranty is made as to information contained in or omitted from the Registration Statement in reliance upon and in conformity with written information furnished to the Company through the Representatives by or on behalf of any Underwriter expressly for use therein, which information is specified in Section 10 hereof.

Counsel to the indemnified parties shall be selected as follows: counsel to the Underwriters and the other indemnified parties referred to in Section 6(a) above shall be selected by the Representatives; and counsel to the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Underwriters and the other indemnified parties referred to in Section 6(a) above; and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for 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 or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim 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 any indemnified party. An indemnifying party shall not be liable under this Section 6 to any indemnified party regarding any settlement 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 is consented to by such indemnifying party, which consent shall not be unreasonably withheld.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, 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 Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the 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 any 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) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each affiliate, officer, director, employee, partner and member of each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall 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 or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Company or any of its subsidiaries (whether signed on behalf of such officer, the Company or such subsidiary) and delivered to the Representatives or counsel to the Underwriters, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer, director, employee, partner, member or agent of any Underwriter or any person controlling any Underwriter, or by or on behalf of the Company, any officer, director or employee of the Company or any person controlling the Company, and shall survive delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time on or prior to Closing Date (i) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any declaration of a national emergency or war by the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions (including, without limitation, as a result of terrorist

15

activities), in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (ii) (A) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or (B) if trading generally on the NYSE has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by such exchange or by order of the Commission, FINRA or any other governmental authority, or (C) if a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to the Clearstream or Euroclear systems in Europe, (iii) if a banking moratorium has been declared by either Federal or New York authorities, or (iv) if any condition specified in Section 5 shall not have been fulfilled when and as required to be fulfilled.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and except that Sections 4, 6, 7, 9(b), 12, 13 and 14 hereof shall survive such termination and remain in full force and effect.

SECTION 10. Underwriters’ Information.

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

(i) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(ii) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of Securities, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 11 shall 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, the Representatives shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 11.

FORM OF OPINION OF COMPANY COUNSEL

(1) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware.

(2) The Company has corporate power and authority to own or lease, as the case may be, and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus and to enter into, deliver and perform its obligations under the Underwriting Agreement, the Indenture and the Securities.

(3) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(4) Each of the Base Indenture and the Fourth Supplemental Indenture has been duly authorized by all necessary corporate action of the Company, executed and delivered by the Company, and assuming due authorization, execution and delivery thereof by the Trustee, the Indenture constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally or by general principles of equity.

(5) The Securities have been duly authorized and executed by the Company and, when authenticated and delivered in the manner provided for in the Indenture and delivered against payment of the purchase price therefor as provided in the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally or by general principles of equity.

(6) The Registration Statement has become effective under the 1933 Act; the Pre-Pricing Prospectus and the Prospectus and any amendments or supplements thereto have been filed with the Commission pursuant to Rule 424(b) in the manner and within the time period required by Rule 424(b) (without reference to Rule 424(b)(8)); any required filing of each Issuer Free Writing Prospectus pursuant to Rule 433 has been made in the manner and within the time period required by Rule 433(d); and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted by or are pending before the Commission.

(7) The Registration Statement, at the time it first became effective, and the Registration Statement (including the Rule 430B Information), at each deemed new effective date with respect to the Underwriters pursuant to Rule 430B(f)(2), and the Prospectus and any amendments or supplements thereto, as of their respective dates, complied as to form in all material respects with the requirements of the 1933 Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations; it being understood, however, that such counsel need express no view with respect to the Form T-1, Regulation S-T or the financial statements, schedules or other financial data, included in, incorporated by reference in, or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, such counsel may assume that the statements made in the Registration Statement, the General Disclosure Package and the Prospectus are correct and complete.

(8) The statements included in the General Disclosure Package and the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities,” insofar as they purport to constitute summaries of the terms of the Securities, are accurate summaries of the terms thereof in all material respects. The statements included in the General Disclosure Package and the Prospectus under the caption “Material U.S. Federal Income Tax Considerations,” to the extent that such statements purport to describe or summarize the legal matters therein, accurately summarize in all material respects such legal matters.

(9) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is required for the execution, delivery and performance by the Company of each of the Transaction Documents, the issuance and sale of the Securities and compliance by the Company with the terms thereof and the consummation of the transactions contemplated by the Transaction Documents, except for such filings, consents, approvals, authorizations, orders and registrations or qualifications as may be required under applicable state securities laws in connection with the purchase and distribution of the Securities by the Underwriters and any consent, approval, authorization, order, registration or qualification that has been obtained or made, or which if not obtained or made, would not, individually or in the aggregate, have a Material Adverse Effect. With respect to this paragraph (9), such counsel need not express any opinion with respect to consents, approvals, authorizations, orders and registrations or qualifications as may be required under applicable federal or state antifraud laws, rules or regulations.

D-1

(10) The execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated in the Transaction Documents, the Registration Statement, the General Disclosure Package and the Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the General Disclosure Package and the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations under the Transaction Documents do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default, Termination Event or Repayment Event under, or result in the creation or imposition of any Lien upon any property or assets of the Company or any of its subsidiaries pursuant to any Company Document, except for such conflicts, breaches, defaults or Liens that would not, individually or in the aggregate, result in a Material Adverse Effect, nor will such action result in any violation of the provisions of the Organizational Documents of the Company or any Significant Subsidiary or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to us, of any government, government instrumentality or court having jurisdiction over the Company or any of its subsidiaries or any of their respective assets, properties or operations, excluding any anti-fraud or similar law, rule or regulation, nor will such action require any consents, approvals, or authorizations to be obtained by the Company from, or any registrations, declarations or filings to be made by the Company with, any governmental authority under any federal or Texas or New York or statute, rule or regulation applicable to the Company or the Delaware General Corporation Law (other than under the 1933 Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations, or as may be required under the securities or blue sky laws of the various states) that have not been obtained or made.

(11) The Company is not, and, upon the issuance and sale of the Securities as contemplated in the Underwriting Agreement and the receipt and application of the net proceeds therefrom as described in the General Disclosure Package and the Prospectus under the caption “Use of Proceeds,” will not be an “investment company” or an entity “controlled” by an “investment company” as such terms are defined in the 1940 Act.

(12) The Indenture has been duly qualified under the Trust Indenture Act.

In addition, such counsel shall state that, in acting as counsel to the Company in connection with the transactions contemplated by the Underwriting Agreement they have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants and counsel for the Company and representatives of the Underwriters, at which conferences the contents of the Registration Statement, the General Disclosure Package and the Prospectus, and any supplements or amendments to any of the foregoing, 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 in the Registration Statement, the General Disclosure Package, the Prospectus or any supplements and amendments to any of the foregoing, and has made no independent check or verification thereof (except as set forth in paragraph 8 above), nothing has come to such counsel’s attention that would lead such counsel to believe that

(1) the Registration Statement or any post-effective amendments thereto, at the respective times they first became effective, or the Registration Statement or any post-effective amendments thereto (in each case including the Rule 430B Information), at each deemed new effective date with respect to the Underwriters pursuant to Rule 430B(f)(2), 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;

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

(3) the Prospectus and any supplements thereto, as of the date of the Prospectus, as of the date of any such supplement or as of the date of this letter, included or includes 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 the light of the circumstances under which they were made, not misleading,

except in each case that such counsel expresses no view with respect to the Form T-1, Regulation S-T or the financial statements, schedules and other financial or statistical data included in, incorporated by reference in, or omitted from the Registration Statement, the General Disclosure Package, or the Prospectus or any amendment or supplement to any of the foregoing.

Except as otherwise provided herein, in the event that such opinion shall define the term “Registration Statement,” “Pre-Pricing Prospectus,” “Prospectus” or “General Disclosure Package” (rather than indicating that such terms, as used in such opinion, have the respective meanings given thereto in the Underwriting Agreement), such opinion shall define the terms “Registration Statement,” “Pre-Pricing Prospectus” and “Prospectus” to include the documents incorporated or deemed to be incorporated by reference therein.

In rendering such opinion, Company Counsel shall state that such opinion covers matters arising under the laws of the States of Texas and New York, the Delaware General Corporation Law and the federal laws of the United States of America. In rendering such opinion, Company Counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

EXHIBIT E

FORM OF OPINION OF GENERAL COUNSEL

To such counsel’s knowledge, except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending or threatened, against or affecting the Company or any of its subsidiaries which is required to be disclosed in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, or which might reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or to materially and adversely affect the consummation of the transactions contemplated in the Transaction Documents or the performance by the Company of its obligations thereunder.

The Company has an authorized capitalization as set forth in each of the General Disclosure Package and the Prospectus.

Such opinion shall define the term “knowledge” to mean the actual knowledge of such counsel after inquiry of personnel of the Company who have responsibility for the subject matter of such opinion.

In the event that such opinion shall define the term “Registration Statement,” “General Disclosure Package” or “Prospectus” (rather than indicating that such terms, as used in such opinion, have the respective meanings given thereto in the Underwriting Agreement), such opinion shall define the terms “Registration Statement,” “General Disclosure Package” and “Prospectus” to include the documents incorporated or deemed to be incorporated by reference therein.

Ladies and Gentlemen:

We have acted as counsel to National Oilwell Varco, Inc., a Delaware corporation (the “Company”), with respect to certain legal matters in connection with the registration by the Company under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale by the Company of $500,000,000 aggregate principal amount of 3.600% Senior Notes due 2029 (the “Notes”), to be issued and sold pursuant to the Underwriting Agreement, dated November 4, 2019, by and among the Company and the Underwriters named therein (the “Underwriting Agreement”). Capitalized terms used but not defined herein shall have the meanings given to such terms in the Underwriting Agreement.

The Notes are being offered and sold pursuant to a prospectus supplement dated November 4, 2019 (the “Prospectus Supplement”) filed with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b)(5) on November 6, 2019, which supplements the prospectus dated October 30, 2019, (such prospectus, as amended and supplemented by the Prospectus Supplement, the “Prospectus”), included in and forming part of the Registration Statement on Form S-3 (Registration No. 333-234373) (the “Registration Statement”).

The Notes are to be issued pursuant to that certain Indenture, dated as of November 20, 2012 (the “Base Indenture”), by and between the Company and Wells Fargo Bank, National Association, as successor trustee (the “Trustee”), as amended and supplemented by the First Supplemental Indenture, the Second Supplemental Indenture, the Third Supplemental Indenture, each dated as of November 20, 2012, and the Fourth Supplemental Indenture, dated as of November 14, 2019 (collectively, the “Supplemental Indentures” and, together with the Base Indenture, the “Indenture”).

In rendering the opinion set forth below, we have examined and relied upon (i) the Registration Statement, the Prospectus Supplement and the Prospectus, (ii) the Fifth Amended and Restated Certificate of Incorporation of the Company and Amended and Restated By-laws, as amended through the date hereof, (iii) corporate records of the Company including certain resolutions adopted by the Board of Directors and the Pricing Committee of the Board of Directors of the Company relating to the terms and sales of the Notes and related matters, (iv) the Underwriting Agreement, a copy of which is being filed with the Commission, together with this opinion of counsel, as an exhibit to the Company’s Current Report on Form 8-K prior to the closing of the sale of the Notes, (v) the Base Indenture and the Supplemental Indentures, and (vi) such other certificates, statutes and other instruments and documents as we consider appropriate for purposes of the opinions hereafter expressed. In addition, we have reviewed and relied upon certain certificates of officers of the Company and of government officials with respect to certain factual matters that we have not independently verified.

In connection with this opinion, we have assumed that (i) all information contained in all documents submitted to us for review is accurate and complete; (ii) each document submitted to us for review as an original is authentic, each such document that is a copy conforms to an authentic original and all signatures on each such document are genuine; (iii) each person signing documents we examined has the legal authority and capacity to do so; and (iv) each certificate from governmental officials reviewed by us is accurate, complete and authentic, and all official public records are accurate and complete.

On the basis of the foregoing, and subject to the assumptions, qualifications and limitations set forth herein, when the Notes are executed, authenticated, issued and delivered in accordance with the provisions of the Indenture and duly purchased and paid for in accordance with the terms of the Underwriting Agreement, we are of the opinion that the Notes will constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such enforcement may be subject to (i) any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar law affecting the enforcement of creditors’ rights generally, (ii) general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), and (iii) public policy considerations which may limit the rights of parties to obtain certain remedies.

The opinions expressed herein are qualified in the following respects:

We hereby consent to the filing of this opinion as an Exhibit to the Company’s Current Report on Form 8-K filed on or about the date hereof, to the incorporation by reference of this opinion into the Registration Statement and to the statements with respect to us under the heading “Legal Matters” in the Prospectus Supplement.
