From: Linda Lerner [llerner@dom-sec.com] Sent: Wednesday, March 17, 2004 12:24 PM To: rule-comments@sec.gov Subject: S7-10-04 - Request to Testify: Importance: High Domestic Securities, Inc. 160 Summit Avenue Montvale, NJ 07645 Re: File No. S7-10-04 Gentlemen/Ladies: I hereby request permission to testify regarding the above referenced proposal concerning the National Market System on behalf of Domestic Securities, Inc., which owns and operates the ATTAIN ECN. My testimony will focus on the proposed maximum rate that may be charged by ECNs, although I may touch on other matters concerning the NMS proposal, such as the future roles of the various market participants in maintaining transparent, accessible, liquid markets, which Domestic has long supported. We believe that it is vital for the voice of the smaller ECNs to be heard on these matters. A summary of my testimony will be submitted on or before March 26, 2004. My preference would be to testify at the hearing to be held in New York City on April 21, 2004, but, if necessary for your scheduling reasons, I am available to testify on April 1, in Washington. I look forward to participating in this important process. Please inform me as to any time limitations on my testimony so that I may prepare my remarks accordingly. Very truly yours, Linda Lerner General Counsel
