(a) Articles of Incorporation CHS, certified by the Wisconsin Department of Financial Institutions as of a recent date (the “CHS Articles”);

(b) Bylaws of CHS certified as true, correct and complete by CHS (the “CHS Bylaws” and with the CHS Articles, collectively, the “CHS Charter Documents”);

(c) Articles of Organization of CRC, certified by the Wisconsin Department of Financial Institutions as of a recent date (the “CRC Articles”);

(d) Operating Agreement of CRC certified as true, correct and complete by CRC (the “CRC Operating Agreement,” and with the CRC Articles, collectively, the “CRC Charter Documents”);

2. CRC is duly formed, validly existing and in good standing under the laws of the State of Wisconsin.

3. Each Guarantor has the requisite corporate or limited liability company power and authority to execute, deliver and perform its respective obligations under the Transaction Documents to which it is a party.

4.

5. The execution and delivery by each Guarantor of the Transaction Documents to which it is a party, and the performance by each Guarantor of its respective obligations under the Transaction Documents and the consummation by each Guarantor of the transactions effected thereby, have been duly authorized by all necessary corporate or limited liability company action and do not: (i) constitute a breach or violation of the Charter Documents of such Guarantor; (ii) result in a violation of any law, statute or regulation applicable to such Guarantor which, in our experience, is normally applicable to transactions of the type contemplated by the Transaction Documents to which it is a party.

6. Each Guarantor has duly executed and delivered the Transaction Documents to which it is a party other than the Exchange Guarantees.

No consent, approval or authorization of, or permit or license from, or registration with, or notice to any federal or state regulatory authority is required in connection with the execution and delivery by each Guarantor of the Transaction Documents to which it is a party, the performance by such Guarantor of its obligations under the Transaction Documents and the consummation by such Guarantor of the transactions effected thereby, except (i) any such consent, approval, authorization, permit or license that has been requested and obtained, any such registration that has been made, any such notice that has been given, or any such other appropriate action that has been taken on or prior to the date hereof, (ii) such as may be required by orders, decrees and the like that are specifically applicable to the Guarantors, of which we have no knowledge, (iii) such as may be required by agreements or other instruments binding upon the Guarantors, of which we have no knowledge, (iv) as disclosed in the respective Transaction Documents, and (v) as may be required under the securities or “Blue Sky” laws of U.S., state or non-U.S. jurisdiction or other non-U.S. laws.
