Ladies and Gentlemen:

We have acted as special counsel to Unit Corporation, a Delaware corporation (the “Company”), in connection with the proposed issuance and sale from time to time by the Company of its common stock, $0.20 par value per share, in an amount having an aggregate offering price of up to $80,996,909 (the “Shares”) pursuant to the distribution agreement dated April 4, 2017 (the “Original Distribution Agreement”), as amended by the amendment to distribution agreement dated as of March 7, 2018 (the “Amendment” and, the Original Distribution Agreement, as amended by the Amendment, the “Distribution Agreement”), each between the Company and Raymond James & Associates, Inc. (the “Agent”). The Shares are to be issued under the Registration Statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”), filed with the U.S. Securities and Exchange Commission (the “Commission”) on March 14, 2018 (the “Registration Statement”), the base prospectus included in the Registration Statement (the “Base Prospectus”), and the prospectus supplement to be filed with the Commission under Rule 424(b) of the rules and regulations of the Act (the “Prospectus Supplement” and together with the Base Prospectus, the “Prospectus”). 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 the Prospectus, other than as expressly stated herein with respect to the issuance of the Shares.

As counsel, we have examined originals or copies of the Original Distribution Agreement, the Amendment, the Registration Statement, the Prospectus, the Company’s Restated Certificate of Incorporation, as amended, the Company’s By-laws, as amended and restated, and other records, documents, certificates, memoranda and instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters.
