The Company intends to use the net proceeds from the offering for general corporate purposes.
The offer and sale of the notes and the common shares deliverable upon conversion of the notes have not been, and will not be, registered under the Securities Act or any other securities laws, and the notes and such shares cannot be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws. This press release does not constitute an offer to sell, or the solicitation of an offer to buy, the notes or the common shares deliverable upon conversion of the notes, nor will there be any sale of the notes or such shares, in any state or other jurisdiction in which such offer, sale or solicitation would be unlawful.
