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

On April 8, 2015, we received a notice indicating that the NYSE MKT Committee on Securities (the “Committee”) affirmed the determination of the staff of the Corporate Compliance Department of NYSE Regulation, Inc. (the “Staff”) to prohibit the continued listing of our common stock on the NYSE MKT and to initiate delisting proceedings. We were also notified that the Staff determined to suspend trading of our common stock on the NYSE MKT. This notification follows the Company’s previously announced appeal of the Staff’s delisting determination due to our non-compliance with the shareholder equity requirements for continued listing set forth in Sections 1003(a)(i), (ii) and (iii) of the NYSE MKT Company Guide by the end of the maximum 18 month compliance plan period, which expired on November 13, 2014.

Beginning April 9, 2015, our common stock will be traded on the OTCQX marketplace under the ticker symbol BONE.
