Sonex became subject to the periodic reporting requirements of the Securities and Exchange Commission (SEC) upon making an initial public offering of its common stock in 1985. The stock eventually traded in the over-the- counter market and was last quoted on the Pink Sheets Electronic Quotation Service under the symbol "SONX". The Company, however, became deliquent in its annual and quarterly SEC reporting requirements and in July 2007 the SEC revoked the registration of the Company's stock; as a result, the stock ceased public trading. Stock can be sold privately, but there is no established value, market or platform for doing so.
Questions concerning shares held in "street name" in an account at a brokerage or other financial institution should be directed to your investment account representative.

For shareholders whose stock is registered in their own name and reflected by a physical stock certificate, please be advised that Sonex no longer has a stock transfer agent and registrar for its common stock. If you have questions about your stock certificates, please contact George E. Ponticas, Sonex CEO, President, CFO and Secretary.
