The offering is being made to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. Any offers of the convertible notes will be made only by means of a private offering memorandum. None of the convertible notes or any shares of the common stock issuable upon conversion of the convertible notes have been or are expected to be registered under the Securities Act or any state securities laws and, unless so registered, may not be offered or sold in the United States or to U.S. persons except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.
