Ladies and Gentlemen:

We have acted as special Indiana counsel to Skyline Club, Inc., an Indiana corporation (“Skyline Club”) and Knollwood Country Club, Inc., an Indiana corporation (“Knollwood Country Club”) (Skyline Club and Knollwood Country Club are referred to herein, collectively, as the “Indiana Guarantors” and, individually, an “Indiana Guarantor”), in connection with (a) the Registration Statement on Form S-4 (the “Registration Statement”) filed by ClubCorp Club Operations, Inc., a Delaware corporation (the “Company”), the Indiana Guarantors and the other registrant guarantors named therein with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”) , relating to the issuance by the Company of up to $415,000,000 aggregate principal amount of 10% Senior Notes due 2018 (the “Exchange Notes”); and (b) the issuance by the Indiana Guarantors and the other guarantors (collectively, the “Guarantors”) of Guarantees (defined below) under Article 10 of the Indenture with respect to the Exchange Notes.  The Exchange Notes will be issued under an indenture dated as of November 30, 2010 (the “Indenture”), among the Company, the Guarantors (including the Indiana Guarantors) and Wilmington Trust FSB, as trustee (the “Trustee”).  Under Article 10 of the Indenture, the Company and the Guarantors (including the Indiana Guarantors) fully and unconditionally guaranteed (the “Guarantees”) the Exchange Notes when issued. The Company will offer the Exchange Notes and the Guarantees in exchange for up to $415,000,000 aggregate principal amount of its outstanding 10% Senior Notes due 2018 and the related guarantees.

Materials Examined

In connection with the foregoing, we have examined originals or copies of the Registration Statement and the Indenture, which Indenture has been filed with the Commission as an exhibit to the Registration Statement (collectively, the “Transaction Documents”) and the documents listed in the attached Exhibit A, which is made a part hereof.  For the purposes of this opinion letter, the documents listed in Exhibit A are hereinafter referred to collectively as the “Authorization Documents.”

We also have examined the originals, or duplicates or certified or conformed copies, of such corporate and other records of the Indiana Guarantors, certificates and other communications of public officials, certificates of officers of the Indiana Guarantors and such other documents as we have deemed necessary including such information that is set forth below and on Exhibit A and that otherwise has been brought to our attention by certificates executed

and delivered to us by officers of the Indiana Guarantors or the Company, for the purpose of rendering the opinions expressed herein.  As to questions of fact material to those opinions, we have, to the extent we deemed appropriate, relied upon and assumed the accuracy of such records, documents, certificates of officers of the Indiana Guarantors, and certificates and other communications of public officials.  We have made such examination of the laws of the State of Indiana as we deemed relevant for purposes of this opinion, but we have not made a review of, and express no opinion concerning, the laws of any jurisdiction other than the State of Indiana.

Assumptions

We have relied upon and assumed the truth and accuracy of the representations, certifications and warranties made in the Transaction Documents and the Authorization Documents, and have not made any independent investigation or verification of any factual matters stated or represented therein.  Except to the extent expressly set forth herein, we have not undertaken any independent investigation to determine the existence or absence of such facts or circumstances or the assumed facts set forth herein, we accept no responsibility to make any such investigation, and no inference as to our knowledge of the existence or absence of such facts or circumstances or of our having made any independent review thereof should be drawn from our representation of the Indiana Guarantors. In rendering this opinion letter to you, we have assumed with your permission:

(a)The genuineness of all signatures on, and the authenticity of, all documents submitted to us as originals, the conformity to authentic original documents of all documents submitted to us as copies, the due authorization (other than the authorization by the Indiana Guarantors of the Transaction Documents), execution and delivery by the parties thereto (other than the execution and delivery of the Transaction Documents by the Indiana Guarantors) of all documents examined by us, and the legal capacity of each individual who signed any of those documents.

(b)At no time subsequent to the execution and delivery of the Indenture has the Indenture been amended by oral or written agreement or by conduct of the parties thereto and there are no other agreements or understandings among the parties, written or oral, and there is no usage of trade or course of prior dealing among the parties, that would, in either case, define, supplement, or qualify any of  the terms and provisions of the Indenture.

(c)All official public records (including their proper indexing and filing) furnished to or obtained by us, electronically or otherwise, were accurate, complete and authentic when delivered or issued and remain accurate, complete and authentic as of the date of this opinion letter.

The Resolutions of each Indiana Guarantor identified in the attached Exhibit A  continue to be in full force and effect and have not been amended or rescinded since the date of adoption.

(e)The financial condition of the Indiana Guarantors at all relevant times was such as permitted the authorization, execution and performance by each Indiana Guarantor of the Transaction Documents under Ind. Code 23-1-28.

(i)The Exchange Notes and the Indenture are the Company’s valid and legally binding obligations and that the Indenture and the Guarantees are the valid and legally binding obligations of the Company, the Indiana Guarantors (except to the extent set forth in our opinions below), the other Guarantors and the Trustee.

Opinions

Based on the foregoing and upon such investigation as we have deemed necessary, and subject to the assumptions, qualifications, exceptions and limitations set forth herein, we are of the opinion that:

2.Each Indiana Guarantor has the requisite corporate power and authority under Indiana law and its Authorization Documents to (a) execute and deliver the Indenture; and (b) perform its financial obligations thereunder.

3.Each Indiana Guarantor, by either Ingrid Keiser, as Secretary, or Curt McClellan, as Treasurer, (the “Authorized Officer”) of each Indiana Guarantor, has duly authorized, executed and delivered the Indenture.

4.Each Indiana Guarantor, by its Authorized Officer, has duly authorized and issued the Guarantees under the Indenture.

5.The execution and delivery by each Indiana Guarantor of the Indenture does not conflict with or violate (a) any provision of the Authorization Documents of each Indiana Guarantor, (b) any laws of the State presently in effect having general application to corporations organized under the laws of the State, or (c) to our knowledge, any judgment, writ, injunction, decree, order or ruling of any court or Governmental Authority binding on each Indiana

Guarantor (it being understood that we have not undertaken any independent investigation to determine the existence or absence of such facts).
