All capitalized terms not defined herein shall have the meanings ascribed to them in the Agreement.

In connection with the foregoing, the parties hereto wish to amend the Agreement through this Amendment No. 1 to Agreement (this “Amendment”) to make certain changes to the Agreement with effect on and after the date hereof (the “Effective Date”), including to terminate the participation of Stifel as an agent in the offering of Common Stock under the Agreement and include the participation of Virtu Americas LLC as an agent in the offering of Common Stock under the Agreement.

SECTION 1. Amendments to the Agreement. The parties hereto agree, from and after the Effective Date, that:

(a) The Agreement is hereby amended:

1. The definition of “Agents” in the first paragraph of the Agreement is hereby amended to remove the reference to Stifel as an agent (the “Prior Agent”) and add a reference to Virtu Americas LLC (“Virtu”) as an agent in the offering of Common Stock under the Agreement.

2. All references to “Agents” in the Agreement are intended to reference only Roth and Virtu unless and until the Agreement is further amended to add any additional Agent(s).

3. The heading on the first page of the Agreement is hereby amended to delete the name and address of the Prior Agent and insert the name and address of Virtu as follows:

“VIRTU AMERICAS LLC

1633 Broadway, 41st Floor

New York, New York 10019”

(b) The first sentence of Section 1(a) of the Agreement is hereby amended and restated in its entirety to read as follows:

“The Company has prepared and filed with the Commission a registration statement on Form S-3 (File No. 333-282595), including a related Base Prospectus, under the 1933 Act, in respect of the Company’s Common Stock (including the Shares) (collectively, the “Securities”), and any pre-effective amendment thereto.”

(c) Section 1(c) of the Agreement is hereby amended and restated in its entirety to read as follows:

“Independent Accountants. Deloitte & Touche, LLP, who have certified certain financial statements of the Company and its consolidated subsidiaries and delivered their report with respect to the audited consolidated financial statements included or incorporated by reference in the Registration Statement and the Prospectus, are independent public accountants with respect to the Company within the meaning of the 1933 Act. Ernst & Young LLP, who have certified certain financial statements of the Company and its consolidated subsidiaries and delivered their report with respect to the audited consolidated financial statements included or incorporated by reference in the Registration Statement and the Prospectus, are independent public accountants with respect to the Company within the meaning of the 1933 Act.”

(d) Section 1(nn) of the Agreement is hereby amended and restated in its entirety to read as follows:

“Reserve Report and Engineers. Netherland, Sewell & Associates, Inc., whose report regarding the oil, natural gas liquids and natural gas reserves as of December 31, 2024 of the Company and its subsidiaries is incorporated by reference in the Registration Statement, General Disclosure Package and the Prospectus (the “Company Reserve Report”), was, as of the respective dates of such reports, and is, as of the date hereof, an independent petroleum engineer with respect to the Company. The information underlying the estimates of oil and natural gas proved reserves of the Company and its subsidiaries, which the Company prepared and supplied to Netherland, Sewell & Associates, Inc. for the purpose of preparing the Company Reserve Report was true and correct in all material respects on the dates such estimates were made, except for such inaccuracies when taken as whole would not result in the material misstatement of the estimate of proved reserves of the Company and its subsidiaries, the future net cash flows therefrom or the present value thereof, and such information was supplied and was prepared in accordance with customary industry practices. Other than normal production of reserves, intervening market commodity price fluctuations, fluctuations in demand for such products, adverse weather conditions, unavailability or increased costs of rigs, equipment, supplies or personnel, the timing of third party operations and other factors, in each case in the ordinary course of business, and except as disclosed in the General Disclosure Package and the Prospectus, the Company is not aware of any facts or circumstances that would result in a material adverse change in the estimates of the Company’s oil, natural gas liquids and natural gas proved reserves, or the present value of future net cash flows therefrom, as reflected in the reports referenced in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, and the Company Reserve Report. The Company has no reason to believe that the estimates of proved reserves contained in the Company Reserve Report do not fairly reflect the proved reserves of the Company as of the dates indicated therein. Estimates of such reserves and present values as described in the General Disclosure Package and the Prospectus and reflected in the Company Reserve Report comply in all material respects with applicable requirements of Regulation S-X and the industry guidelines in Subpart 1200 to Regulation S-K under the 1934 Act.”

(e) The second sentence of Section 2(d) of the Agreement is hereby amended and restated in its entirety to read as follows:

(h) The first sentence of Section 3(m) of the Agreement is hereby amended and restated in its entirety to read as follows:

“ Upon the Commencement Time (and upon the recommencement of the offering of the Shares under this Agreement following the termination of a suspension of sales as contemplated herein), and within two (2) Business Days after each time after the Commencement Time that (i) the Registration Statement or the Prospectus shall be amended or supplemented to include additional amended financial information, (ii) the Shares are delivered to an Agent as principal pursuant to a Terms Agreement, (iii) the Company files with the Commission an Annual Report on Form 10-K, or (iv) at the Agents’ request and upon reasonable advance notice to the Company (such recommencement date and each such date referred to in (i), (ii), (iii) and (iv) above, an “Auditor Representation Date”), there is filed with the Commission any document which contains financial information incorporated by reference into the Prospectus, the Company will cause Deloitte & Touche, LLP, Ernst & Young, LLP, and/or other independent accountants reasonably satisfactory to the Agents (the “Accountants”), to furnish to the Agents a letter or letters, dated the date of effectiveness of such amendment or the date of filing of such supplement or other document with the Commission, as the case may be, in form reasonably satisfactory to the Agents, of the same tenor as the letter referred to in Section 6(d) hereof, but modified as necessary to relate to the Registration Statement, the General Disclosure Package and the Prospectus, as amended and supplemented, or to the document incorporated by reference into the Prospectus, to the date of such letter.”
