LEGAL PROCEEDINGS	NOTE 14 — LEGAL PROCEEDINGS: *Kayne Litigation.* On July 7, 2011, the Company was served with an amended complaint (the “Complaint”) filed in the United States District Court for the Central District of California alleging, among other things, that the Company, certain of its present and former directors and other entities or individuals now or previously associated with Grande, intentionally interfered with the ability of the plaintiffs to collect on a judgment (now approximately $47 million) they had against Grande by engaging in transactions (such as the dividend paid to all shareholders in March 2010) which transferred assets out of the United States. The Complaint also asserts claims under the civil RICO statute and for alter ego liability. In the Company’s opinion, the claims appear to be devoid of merit.

NOTE 14 — LEGAL PROCEEDINGS:

Kayne Litigation. On July 7, 2011, the Company was served with an amended complaint (the “Complaint”) filed in the United States District Court for the Central District of California alleging, among other things, that the Company, certain of its present and former directors and other entities or individuals now or previously associated with Grande, intentionally interfered with the ability of the plaintiffs to collect on a judgment (now approximately $47 million) they had against Grande by engaging in transactions (such as the dividend paid to all shareholders in March 2010) which transferred assets out of the United States. The Complaint also asserts claims under the civil RICO statute and for alter ego liability. In the Company’s opinion, the claims appear to be devoid of merit. Accordingly, on September 27, 2011, Emerson moved to dismiss the action for failure to state a claim (the “Motion”). On or about February 27, 2012, the Court dismissed the intentional interference claim and portions of the Civil RICO claim with leave to re-plead, but denied the Motion to dismiss the alter ego claim. On March 19, 2012, the plaintiffs filed a Second Amended Complaint setting forth the same claims as the Complaint. On April 20, 2012, the Company moved to dismiss the re-pleaded intentional interference and RICO claims, and oral arguments on this motion were held on June 18, 2012. The Company is awaiting the Court’s ruling on the motion. In the interim, the parties have exchanged document discovery requests and responses, but as of yet no documents have been produced. This action has been scheduled for an April 23, 2013 trial date. Emerson is defending the action vigorously.

Except for the litigation matters described above, the Company is not currently a party to any legal proceedings other than litigation matters, in most cases involving ordinary and routine claims incidental to our business.
