Gentlemen:
    
   
     I have acted as counsel to Wolverine Energy, L.L.C., a Michigan limited

of the Company (the "Interests").  I have participated in the preparation and
filing with the U.S. Securities and Exchange Commission of a Registration
Statement on Form SB-2 (Registration No. 33-95156)  with respect to the
Interests in order the effect their registration under the Securities Act of
1933, as amended (the "Securities Act").  I participated in the preparation of
the Prospectus dated as of                      , 1998, contained within such
Registration Statement with respect to the Company and the Interests which has
been distributed to offerees and purchasers of the Interests in connection with

     Prior to rendering the opinions expressed herein, and in preparation
therefore, I have reviewed and relied upon the following:
    
   
     1.   The Prospectus and the Appendices thereto, including, but not limited

     2.   A Questionnaire completed as of                   , 1998, by George H.
Arbaugh, Jr.
    
   
     3.   The form of Selected Dealer Agreement (the "Dealer Agreement")
proposed to be entered into by and between the Company and each NASD-member
securities broker/dealer (each, a "Selected Dealer") which is retained to
solicit offers to purchase Interests on the terms described in the Prospectus.
    
   
     4.   The certificate of the Manager with respect to compliance with Rule

each affiliate of any of them.
    
   
     5.   The form of Administrative Services Agreement proposed to be entered
into by and between the Company and the Manager with respect to the provision by
the Manager of administrative services and management assistance to the Company.
    
   
     6.   The form of Turnkey Agreement proposed to be entered into by and
between the Company and the Manager with respect to the acquisition by the
Company from the Manager of working interests in up to              net wells.
    
   
     7.   The Operating Agreements by and between

in interest pursuant to which (i) the Project will be operated, and (ii) the
Manager obtained the interest in the Project which will be conveyed to the
Company pursuant to the Turnkey Agreement.
    
   
I have also examined and relied upon such other instruments, documents, reports,
memoranda and statements, and interviews conducted with such personnel of the
Manager as I deemed appropriate in the preparation and rendering of the opinions
expressed herein.
    
   
     In issuing the opinions expressed herein, I have assumed the accuracy and
completeness of the information furnished to me on behalf of the Company by the
Manager and its officers and 

                                          27

employees, and I have further assumed that the Offering will be made in
compliance with the descriptions of such matters in the Prospectus, the terms of
the Dealer Agreement and the applicable provisions of the Securities Act.
    
   
     Based upon and subject to the foregoing, I am of the opinion that:
    
   
          (i)   The offering and sale of the Interests satisfies the conditions
     of Rules 505 and 506 of Regulation D under the Securities Act and
     accordingly is exempt from the registration requirements of Section 5 of
     the Securities Act by reason of the exemption afforded by Section 4(2) of
     the Securities Act as a transaction not involving any public offering.
    
   
          (ii)  The offering and sale of the Interests should not be combined
     with any other offering of securities by the Manager or any of its
     affiliates by the Commission or the securities regulatory authority of any
     state for the purpose of determining whether the Interests should be
     registered under Section 5 of the Securities Act or the securities laws and
     regulations of any state as being part of a public offering of securities.
    
   
     The foregoing opinions are expressly subject to any one or more or all of
the qualifications that:
    
   
          (I)   the enforceability of the Dealer Agreement and each other
     document referred to expressly or by implication in the opinions expressed
     above is limited by any applicable bankruptcy, insolvency, reorganization,
     moratorium or similar laws or by other laws affecting the enforcement of
     creditors' rights from time to time;
    
   
          (II)  I express no opinions as to whether any remedial,
     indemnification or contribution provisions are enforceable;
    
   
          (III) the enforceability of the Dealer Agreement and each other
     document referred to expressly or by implication in the opinions expressed
     above is subject to general principles of equity (regardless of whether
     such enforceability is considered in a proceeding in equity or at law);
    
   
          (IV)  I express no opinion as to the enforceability of (i) self-help
     provisions, (ii) provisions which purport to establish evidentiary
     standards, or (iii) provisions relating to waiver of remedies (or the delay
     or omission of enforcement thereof), liability limitations with respect to
     third parties or liquidated damages;
    
                                          28



   
          (V)   I make no representation that I have independently verified
     (except for a review of all documents attached or referred to in the
     Prospectus and the documents and other information specifically described
     hereinabove), the accuracy or adequacy of the statements in the Prospectus;
     and
    
   
          (VI)  with respect to the Prospectus and all documents annexed
     thereto or referred to therein and the documents and other information
     described or referred to hereinabove, I have assumed the authenticity of
     all documents purported to be and submitted to and reviewed by me as
     originals, the conformity to the original of all documents purported to be
     and submitted to and reviewed by me as copies, the authority of the
     signatories to each such document to sign and to thereby bind themselves as
     individuals or the entity that they purport to represent as representative
     and the authenticity of each such signature.
    
   
     This opinion letter may be relied upon by you only in connection with the
issuance of the Interests pursuant to the Dealer Agreement and the Prospectus
and may not be used or relied upon by you or any other person for any purpose
whatsoever, except to the extent authorized in the Accord, without and in each
instance my prior written consent.
    
   
                              Very truly yours,
