We have not communicated directly with any of the Companies in connection with the preparation of this opinion letter, and other than the preparation and delivery of this opinion letter, we have not participated in any other aspects of the transactions contemplated by the Transaction Documents and do not represent any of the Companies in connection with other matters.

(iii) a certificate of an officer of Rep Sales certifying as to (a) copies of resolutions of the Board of Directors of Rep Sales adopted July 20, 2011, with respect to the Transaction Documents and the transactions contemplated thereby, (b) incumbency with respect to an officer of Rep Sales, and (c) certain other matters and the resolutions attached thereto;

(iv) a copy of the articles of incorporation of Rykodisc certified as of January 24, 2012 as a true copy by the Minnesota Secretary of State, and a copy of the bylaws of Rykodisc certified as of January 25, 2012 as a true copy by the Assistant Secretary of Rykodisc (collectively, the “Rykodisc Constituent Documents”);

We have also examined such other documents, and have reviewed such questions of law, as we have considered necessary and appropriate for the purposes of this opinion. In addition, as to questions of fact material to the opinions hereinafter expressed, we have, when relevant facts were not independently established by us, relied upon certificates of officers of the Companies and of public officials, and we have assumed that all such facts are true and correct as of the date of this opinion. We have not independently examined the records of any court or public office in any jurisdiction, and our opinion is subject to matters which examination of such records would reveal. Without limiting the generality of the foregoing, we have relied upon certificates of officers of the Companies and the representations contained therein, and we have assumed that all such representations are true and correct as of the date of this opinion. In rendering such opinions, we have not conducted any independent investigation of any of the Companies or

consulted with other attorneys in our firm with respect to the matters covered thereby. No inference as to our knowledge with respect to the factual matters upon which we have so qualified our opinions should be drawn from the fact of our representation of the Companies.

In rendering the opinions expressed below, we have assumed, without verification, that:

(A) The authenticity of all documents submitted to us as originals.

(B) The genuineness of all signatures.

(C) The legal capacity of natural persons.

Based upon the foregoing and upon such investigation as we have deemed necessary, and subject to the qualifications set forth below, we are of the opinion that:

1. Based solely on the respective Good Standing Certificates, each of the Companies is a corporation that is validly existing and in good standing under the laws of the State of Minnesota.

2. Each of the Companies had the corporate power to execute and deliver the Transaction Documents executed by it at the time such Transaction Documents were executed and delivered, and has the corporate power to perform its obligations thereunder, and each Company has taken all requisite corporate action to authorize the execution, delivery and performance of the Transaction Documents executed by it.

3. Each of the Transactions Documents to which it is a party was duly executed and delivered by the respective Companies.

SCOPE OF OPINION
