                   Registration
Statement on Form S-3 under the Securities Act of 1933

Ladies and Gentlemen:

We
have acted as counsel for Magnum Hunter Resources, Inc., a Nevada corporation (the
Company), in connection with the registration by the Company under the
Securities Act of 1933 (the Act) of the offer and sale by the Company from
time to time, pursuant to Rule 415 under the Act, of (i) shares of common stock, par
value $.002 per share, of the Company (the Common Stock), (ii) shares of
preferred stock, par value $.001 per share, of the Company in one or more series (the
Preferred Stock), which may be issued in the form of depositary shares
evidenced by depositary receipts (the Depositary Shares), (iii) warrants
(Warrants) to purchase Debt Securities (as defined below), Preferred Stock,
Depositary Shares or Common Stock (iv) the Companys unsecured debt securities,
in one or more series, consisting of notes, debentures or other evidences of indebtedness
(the Debt Securities), and (v) guarantee agreements
(Guarantees) by twelve subsidiaries of the Company (the Subsidiary
Guarantors) named in the Registration Statement (as defined below) with respect to
the Debt Securities (such Debt Securities, Preferred Stock, Depositary Shares, Warrants,
Common Stock and Guarantees (as defined below) are collectively referred to herein as the
Securities). The Securities will be offered in amounts, at prices and on terms
to be determined and to be set forth in supplements to the Prospectus contained in the
Companys Registration Statement on Form S-3 (Registration No. 333-109188), as
amended, to which this opinion is an exhibit (the Registration Statement).

We
have examined originals or copies, certified or otherwise identified to our satisfaction,
of (i) the certificate of incorporation and bylaws of the Company and the
corresponding organizational documents of each Subsidiary Guarantor, each as amended to
the date hereof (the Organizational Documents), (ii) the Form of Senior
Indenture and the Form of Subordinated Indenture (collectively, the Indenture)
relating to the Debt Securities incorporated by reference as an exhibit to the
Registration Statement and (iii) such other certificates, instruments and documents
as we considered appropriate for purposes of the opinions hereafter expressed. In
addition, we reviewed such questions of law as we considered appropriate.

In
connection with this opinion, we have assumed that (i) the Registration Statement,
and each amendment thereto (including post-effective amendments), will have become
effective; (ii) a prospectus supplement (a Prospectus Supplement) will
have been prepared and filed with the Securities and Exchange Commission (the
Commission) describing the Securities offered thereby; (iii) all
Securities will be issued and sold in compliance with applicable federal and state
securities laws and in the manner stated in the Registration Statement and the applicable
Prospectus Supplement; (iv) a definitive purchase,

underwriting or similar agreement
with respect to any Securities offered will have been duly authorized and validly executed
and delivered by the Company and the other parties thereto; (v) at the time of any
offering or sale of Securities, the Company will have such number of shares of Common
Stock or Preferred Stock, if applicable, as set forth in such offering or sale, authorized
and available for issuance; and (vi) any Securities issuable upon conversion,
exchange or exercise of any Security being offered will be duly authorized, created and,
if appropriate, reserved for issuance upon such conversion, exchange or exercise.

Based
upon the foregoing and subject to the limitations and qualifications set forth below, we
are of the opinion that:

          the Company or to the extent permitted by the General Corporation Law of Nevada,

          necessary corporate action to approve the issuance of and the terms of the
          offering of the shares of Common Stock and related matters; and
          (ii) certificates representing the shares of Common Stock have been duly
          executed, countersigned, registered and delivered either (a) in accordance
          with the applicable definitive purchase, underwriting or similar agreement
          approved by the Board upon payment of the consideration therefor (not less than
          the par value of the Common Stock) provided for therein, or (b) upon
          conversion, exchange or exercise of any other Security in accordance with the
          terms of such Security or the instrument governing such Security providing for
          such conversion, exchange or exercise as approved by the Board, for the
          consideration approved by the Board (not less than the par value of the Common
