Re: 2008 Registration Statement on Form S-1 (originally filed on Form SB-2); Tax Matters

Dear Governors:

As counsel for MinnErgy, LLC (the “Company”), we furnish the following opinion in connection with the proposed issuance by the Company of up to 89,000,000 of its membership interests (the “Units”).

We have acted as legal counsel to the Company in connection with its offering of the Units. As such, we have participated in the preparation and filing with the Securities and Exchange Commission under the Securities Act of 1933 of a Form S-1 Registration Statement dated May 14, 2007 relating to that offering (the “Registration Statement”), together with all pre-effective amendments thereto.

You have requested our opinion as to matters of federal tax law that are described in the Registration Statement. We are assuming that the offering will be consummated and that the operations of the Company will be conducted in a manner consistent with that described in the Registration Statement. We have examined the Registration Statement and such other documents as we have deemed necessary to render our opinion expressed below.

Based on the foregoing, all statements relating to the Company’s classification as a partnership for federal income tax purposes and the taxation of investors on their allocable share of the Company’s income, gains, losses and deductions recognized by the Company without regard to cash distributions as described under the section heading, “Federal Income Tax Consequences of Owning Our Units” in the Registration Statement constitute our opinion. That section of the Registration Statement is a description of the material federal income tax consequences that are expected to arise from the ownership and disposition of Units, insofar as it relates to matters of law and legal conclusions. That section is the opinion of counsel on all material federal income tax consequences to prospective Unit holders of the ownership and disposition of Units.
