Date: 4/7/99 9:32 AM Subject: S7-5-99 I am writing to you on behalf of U.S. Digital Communications,Inc. -- a corporation the common stock of which is traded on the OTCBB. We are at an early stage of our development and have found that the liquidity provided our stock by bulletin board quotation has been important in raising much needed capital through private placements. It is important that our investors know that when either through registration or exemption their stock becomes salable, they will be able to trade it in an efficient market. We are very concerned that the proposed rule will lead reputable Market Makers, which range from large firms, wholesale Market Makers, highly regarded regional firms and specialist boutiques that trade bank stocks or distressed securities, to stop submitting priced quotations and possibly exit the market sector completely. The consequence will be that the reputable Market Makers will cease quoting prices or exit the Pink Sheet and OTCBB market and the legitimate securities will suffer a loss of price transparency and liquidity. This could be a serious blow to many firms like ours. We urge the Commission to continue in its efforts to improve the markets, but not by initiatives such as the proposed Rule 15c2-11 that may well result in shutting them down. Edward J. Kopf Exec. V.P. U.S. Digitial Communications, Inc.
