Instinet Group Receives Second Request From DOJ

Instinet Group Incorporated (NASDAQ: INGP) announced today that in connection with the Department of Justice's ("DOJ") investigation under the Hart-Scott-Rodino Antitrust Improvements Act of its pending acquisition by The Nasdaq Stock Market, Inc. ("Nasdaq"), the DOJ has issued a Request for Additional Information and Documentary Materials (a "Second Request") to Instinet Group Incorporated ("Instinet") and Nasdaq. The Second Request suspends the 30-day period in which the DOJ is required to conclude its investigation and make a determination on the Nasdaq/Instinet transaction. A new 30-day period will commence once Instinet and Nasdaq substantially complete their replies to the Second Request. The parties anticipated receiving this Request, and continue to work with the DOJ. The parties believe that the Second Request should not affect the anticipated timing of the merger closing.
