Re:

Registration Statement on Form S-4; Shares of Common Stock, par value $0.01 per share, of CNX Resources Corporation

Ladies and Gentlemen:

We have acted as special counsel to CNX Resource Corporation, a Delaware corporation (“CNX”), in connection with the proposed issuance of common stock, par value $0.01 per share, of CNX (the “Shares”), pursuant to the terms and conditions of the Agreement and Plan of Merger, dated as of July 26, 2020, by and among CNX, CNX Resources Holdings LLC, a Delaware limited liability company and a wholly owned subsidiary of CNX, CNX Midstream Partners LP, a Delaware limited partnership (“CNXM”), and CNX Midstream GP LLC, a Delaware limited liability company and the general partner of CNXM (the “Merger Agreement”).

The Shares are included in a registration statement on Form S-4 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission (the “Commission”) on August 12, 2020 (as amended, the “Registration Statement”). This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related consent statement/prospectus, other than as expressly stated herein with respect to the issuance of the Shares.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of CNX and others as to factual matters without having independently verified such factual matters. We are opining herein as to the General Corporation Law of the State of Delaware (the “DGCL”), and we express no opinion with respect to any other laws.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof, upon issuance and delivery of the Shares in the manner contemplated by the Registration Statement and the Merger Agreement, the Shares will be validly issued, fully paid and nonassessable. In rendering the foregoing opinion, we have assumed that CNX will comply with all applicable notice requirements regarding uncertificated shares provided in the DGCL.
