Ladies and Gentlemen:

I have acted as Senior Legal Counsel, Legal Corporate of Equinor ASA, a company existing under the Norwegian Public Limited Liability Companies Act (the “Company”) and Equinor Energy AS, a company existing under the Norwegian Private Limited Liability Companies Act and a wholly owned subsidiary of the Company (the “Guarantor”) in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”) of (i) $250,000,000 aggregate principal amount of the Company’s 4.250% Fixed Rate Notes due 2028; (ii) $250,000,000 aggregate principal amount of the Company’s 4.500% Fixed Rate Notes due 2030; and (iii) $1,000,000,000 aggregate principal amount of the Company’s 4.750% Fixed Rate Notes due 2035 (collectively, the “Debt Securities”) and the related guarantees thereof by the Guarantor (the “Guarantees”). I am delivering this opinion pursuant to the requirements of the Securities Act.

In connection with my opinion, I have examined such corporate records, certificates and other documents and such questions of law as I have deemed necessary or appropriate for purposes of this opinion.

Based upon and subject to the foregoing, I am of the opinion that:

(a)	the Company has been duly incorporated, is validly existing as a public limited company (allmennaksjeselskap) under the laws of the Kingdom of Norway, and has the requisite power to issue the Debt Securities and perform its obligations thereunder;

(b)	the Guarantor has been duly incorporated, is validly existing as a limited company (aksjeselskap) under the laws of the Kingdom of Norway, and has the requisite power to enter into and perform its obligations under the Guarantees; and

(c)

the Debt Securities have been duly authorized, executed, issued and delivered, and the Guarantees have been duly authorized, executed and delivered, the Debt Securities constitute valid and legally binding obligations of the Company and the Guarantees constitute valid and legally binding obligations of the Guarantor, in each case, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.
