Lomak Petroleum, Inc.
500 Throckmorton Street
Fort Worth, Texas  76102

Ladies and Gentleman:

     We have acted as counsel to Lomak Petroleum, Inc., a Delaware corporation
(the "Company"), in connection with the preparation of the Company's
Registration Statement on Form S-3, Registration Statement No. 333-23955 (the
"Registration Statement"), relating to the proposed offer and sale by certain
securityholders of the Company of up to an aggregate of 4,287,249 shares of the
Company's common stock par value $.01 per share (the "Shares"), and $55,000,000
aggregate principal amount of 6% Convertible Subordinated Debentures due 2007
(the "Debentures"). Of the shares of Common Stock registered by the Registration
Statement, (a) 1,410,106 shares are already outstanding (the "Outstanding
Shares"), (b) 2,857,143 shares are issuable upon conversion of the Debentures
(the "Debenture Shares") and (c) 20,000 shares are issuable upon exercise of
currently outstanding warrants (the "Warrant Shares"). In our capacity as
counsel of the Company, we are passing on certain legal matters in connection
with the registration of the sale of the Shares and the Debentures. At your
request, this opinion is being furnished to you for filing as an exhibit to the
Registration Statement.

     In connection with rendering this opinion, we have examined such
certificates, instruments and documents and reviewed such questions of law as we
have considered necessary or appropriate for the purpose of this opinion. In
addition, we have relied as to factual matters on certificate of certain public
officials and officers of the Company.

     Based upon the foregoing examination and review, we are of the opinion
that:

         (i)      The Outstanding Shares are duly and validly authorized and 
                  legally issued, fully paid and nonassessable;

         (ii)     The Debenture Shares will, upon conversion of the Debentures
                  in accordance with the terms thereof, be duly and validly
                  authorized and legally issued, fully paid and nonassessable;

         (iii)    The Warrant Shares will, upon exercise of the applicable
                  warrants in accordance with the terms thereof, be duly and
                  validly authorized and legally issued, fully paid and
                  nonassessable;

         (iv)     The Debentures have been duly authorized for issuance, and
                  constitute legally issued and binding obligations of the
                  Company enforceable in accordance with their terms and
                  entitled to the benefits of the Indenture, except to the
                  extent that such enforceability may be limited by applicable
                  bankruptcy, insolvency, fraudulent conveyance, reorganization,
                  moratorium and other laws affecting creditors' rights
                  generally and by general equitable principles (whether
                  considered in a proceeding in equity or at law).

     The foregoing opinion is limited to the laws of the United States of
America and to the General Corporation Law of the State of Delaware. For
purposes of this opinion, we assume that the Shares will be issued in compliance
with all applicable state securities or Blue Sky laws.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. In giving this consent, however, we do not hereby admit
that we are within the category of persons whose consent is required under
Section 7 of the Securities Act of 1933 and the rules and regulations of the
Securities and Exchange Commission thereunder.

                                            Very truly yours,

                                            VINSON & ELKINS L.L.P.
