Date: 12/08/1999 11:15 AM Comment on File No. S7-24-99 Dear Sir or Madam; As an individual who invests primarily in small cap stocks, I frequently become interested in investing in the stock of those companies listed on the OTC BB. As an effort to reduce the extensive manipulation of OTC BB stocks, it is imperative that the proposal to extend "short sale" regulations to OTC BB stocks. Such rules have already proven to be helpful on National Exchanges, and should be applied to all trading of public stocks, across the board. Thank you. Sincerely, Gary J. Marks
