          ---------------------------------------------------------------

Gentlemen:

     You are currently engaged in the registration of an offering of limited 
liability company memberships (referred to in your offering materials as 
"Investor Interestholder Interests"), in up to 10 Michigan limited liability 
companies for which Wolverine Energy, L.L.C. will serve as manager, with the 
United States Securities and Exchange Commission (the "SEC"), and various 
state securities agencies. You have retained us for the limited purpose of 
reviewing the offering for compliance with the Michigan Limited Liability 
Company Act (the "Act"), and in connection with that review, you have asked 
that we render the opinion stated below.

     In rendering our opinion, we have reviewed the Registration Statement, 
as amended, that was filed with the SEC on August 6, 1998, the Articles of 
Organization for the Wolverine Energy 1998-1999(A) Development Company, 
L.L.C. that were filed with the State of Michigan on June 3, 1998, and the 
form of Company Operating Agreement that has been represented to us by you 
will be signed at the time that the first Investor Interestholder is admitted 
to each of the limited liability companies included within the SEC 
registration. We have considered such matters of law and fact, and relied 
upon such certificates and other information furnished to us, as we have 
deemed appropriate as a basis for our opinion set forth below.

     This opinion letter is governed by, and shall be interpreted in 
accordance with the Legal Opinion Accord (the "Accord") of the ABA Section of 
Business Law (1991). As a

consequence, it is subject to a number of qualifications, exceptions, 
definitions, limitations on coverage and other limitations, all more 
particularly described in the Accord, and this opinion letter should be read 
in conjunction with the Accord.

     Based on the foregoing, it is our opinion that:

Upon filing of the Articles of Organization for the limited liability 
companies with the Michigan Department of Consumer and Industry Services 
(which has already occurred with respect to the Wolverine Energy 1998-1999(A) 
Development Company, L.L.C.) and upon signing of the form of Company 
Operating Agreement for the limited liability companies by the Manager and 
the Manager as attorney-in-fact for the Investor Interestholders pursuant to 
validly signed and legally binding powers of attorney, the Investor 
Interestholder Interests will be legally issued, and upon payment in full of 
the subscription price by the Investor Interestholders, will be fully paid 
and nonassessable.

     This opinion is limited to Michigan law. A copy of this opinion letter 
may be delivered by you to the SEC, any state securities regulatory agency, 
any broker-dealer that has entered into a Soliciting Dealer Agreement with 
you for the sale of the Investor Interestholder Interests, and any certified 
public accountant or lawyer retained by you to assist you with the 
registration of the Investor Interestholder interests. This opinion letter 
may not be used or relied upon by anyone else for any purpose whatsoever, 
other than in response to a court order, without our prior written consent.

                              Very truly yours,

                   FRASER TREBILCOCK DAVIS & FOSTER, P.C.
