We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. We also consent to the reference to our firm under the heading “Legal Matters” in the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission. This opinion and consent may be incorporated by reference in a subsequent registration statement filed pursuant to Rule 462(b) of the Rules with respect to the registration of additional Securities for sale in any Offering contemplated by the Registration Statement and shall cover such additional Securities.

Our advice on every legal issue addressed in this letter is based exclusively on the internal law of the State of New York, the Limited Liability Company Act of the State of Illinois and the General Corporation Law of the State of Delaware (including the statutory provisions, all applicable provisions of the relevant state constitutions and reported judicial decisions interpreting the foregoing) and represents our opinion as to how that issue would be resolved were it to be considered by the highest court in the jurisdiction which enacted such law. The manner in which any particular issue relating to the opinions would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court involved chose to exercise the wide discretionary authority generally available to it. This letter is not intended to guarantee the outcome of any legal dispute which may arise in the future. For purposes of our opinion that the Guarantees will be binding obligations of the Guarantors, we have, without conducting any research or investigation with respect thereto, relied on the opinion of Foley & Lardner LLP with respect to the Wisconsin Guarantor that such Guarantees do not conflict with, or require consents under, the corporate or limited liability company laws of Wisconsin. We are not licensed to practice in Wisconsin, and we have made no investigation of, and do not express or imply an opinion on, the laws of such state.

We do not find it necessary for the purposes of this opinion, and accordingly we do not purport to cover herein, the application of the securities or “Blue Sky” laws of the various states to the issuance and sale of the Securities.

This opinion is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein. The Securities may be issued from time to time on a delayed or continuous basis, and this opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect. We assume no obligation to revise or supplement this opinion should the present laws of the States of New York, Illinois or Delaware be changed by legislative action, judicial decision or otherwise after the date hereof.

This opinion is furnished to you in connection with the filing of the Registration Statement and is not to be used, circulated, quoted or otherwise relied upon for any other purpose.

Sincerely,

/s/ KIRKLAND & ELLIS LLP
