Except as otherwise indicated herein, capitalized terms used in this opinion letter are defined in the Agreement.  In such capacity, we have reviewed the following documents:  (a) the Agreement; (b) the Substation Use and Easement Agreement; (c) the Management and Administration Agreement; (d) the Meteorological Data Sharing Agreement; (e) the Assignment and Assumption Agreement.  In rendering our opinion we have also examined such certificates of public officials, corporate and limited liability company documents and records and other certificates and instruments as we have deemed necessary for the purposes of the opinion herein expressed.

The Substation Use and Easement Agreement, Management and Administration Agreement, Meteorological Data Sharing Agreement and Assignment and Assumption Agreement are referred to collectively as the Ancillary Agreements.  We have assumed for purposes of the opinions set forth (a) that the Agreement and the Ancillary Agreements have been duly authorized, executed and delivered by the parties thereto other than Windpower III and Midwest, and (b) that each of the parties to the Agreement, other than Windpower III and Midwest, is duly organized and validly existing under the laws of its respective jurisdiction of organization and has the power, authority and legal right to perform the Agreement.

We express no opinion with respect to the effect of any law other than the law of the State of Iowa and the State of Delaware (with our opinion limited only to the Delaware Limited Liability Company Act and the Delaware General Corporation Law). For purposes of our opinions regarding the Delaware Limited Liability Company Act, we have reviewed the reviewed [insert treatise on which review is based], and our opinion is based solely on such review.

The execution and delivery of the Agreement and Ancillary Agreements by Midwest have been duly authorized by all requisite action of Midwest and the Agreement and the Ancillary Agreements have been duly executed and delivered by Midwest.  The Agreement and the Ancillary Agreements represent, as applicable, the valid and binding obligations of Windpower II, Windpower III and Services, enforceable against each of them, as applicable, in accordance with their terms.  The execution and delivery by Windpower II and Windpower III of the Agreement and, as applicable, by Windpower II and Services of the Ancillary Agreements, and the acts of Midwest in executing and delivering the Agreement and Ancillary Agreements on behalf of Windpower II, Windpower III and Services, do not (a) conflict with or violate any provision of the Operating Agreement of Windpower II, Windpower III, Services or the articles of incorporation of Midwest, or (b) to the best of our knowledge, (i) conflict with or violate or result in a breach of any of the provisions of, or constitute a default under, or result in the creation or imposition of a lien, charge or encumbrance upon any of the properties or assets of Windpower II, Windpower III, Services or Midwest pursuant to, any agreement or instrument to which Windpower II, Windpower III, Services or Midwest, as applicable, is a party or by which any of its properties is bound, or (ii) conflict with or violate any judgment, order, writ, injunction or decree binding on Windpower II, Windpower III, Services or Midwest, or (c) conflict with or violate any law, rule, regulation or ordinance applicable to Windpower II, Windpower III, Services or Midwest.  To the best of our knowledge, there are no material pending or threatened lawsuits, claims or criminal proceedings against Windpower II, Windpower III Services or Midwest or specifically applicable to the Site.  Our opinions set forth above are modified by and subject to the following qualifications:  (a) The enforcement of the Agreement is subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and other laws of general application related to or affecting the enforcement of creditors' rights or the enforcement of the security provided by the Agreement;  (b) Applicable laws may adversely affect the enforcement of certain provisions of the Agreement and Ancillary Agreements relating to events of default and certain rights and remedies provided for therein, but such laws do not, in our opinion, make the remaining remedies available in respect thereof, inadequate for the practical realization of the benefits of the security intended to be provided thereby; and  (c) The availability of equitable remedies such as specific performance, injunctive relief or other equitable remedies involving any proceedings (legal or equitable) may limit the enforceability of any of the provisions of the Agreement and the Ancillary Agreements.  The foregoing opinions may be relied upon by MGE, its successors and/or assigns, and their respective counsel, but may not be relied upon by any other party.
