Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

We failed to provide NYSE MKT LLC (the "Exchange") with a timely notice of the record date for our 2012 Annual Meeting of Shareholders.

On July 2, 2012, we received a letter from the Exchange (the "NYSE Letter") pursuant to Sections 703 and 1009 of the Exchange Company Guide indicating that we failed to provide the Exchange with at least ten days advanced notice of the record date for our 2012 annual meeting of shareholders. The Exchange issued a public warning letter as a result of our failure to satisfy the ten day advanced notice requirement of Section 703 of the Exchange Company Guide; however, this action will NOT result in the suspension or delisting of our securities from the Exchange.

We confirm June 8, 2012 as the record date for our upcoming 2012 Annual Meeting of Shareholders to be held on July 27, 2012.
