("NASD") had issued and outstanding 10,806,494 warrants ("Warrants") to purchase up to an aggregate of 43,225,976 shares of The Nasdaq Stock Market, Inc.'s ("Nasdaq") common stock, par value $0.01 Page 3 of 5 Pages

per share (the "Common Stock"), held by or on behalf of NASD. Each Warrant is exercisable for one share of Common Stock in each of four consecutive exercise periods of approximately one-year each (the first exercise period expired at the close of business on June 27, 2003, and the second period expired at the close of business on June 30, 2004). Until Nasdaq is registered as an exchange ("Exchange Registration"), the shares of Common Stock underlying the Warrants are subject to a voting trust agreement (the "Voting Trust") whereby a voting trustee will vote all shares of Common Stock underlying unexpired and unexercised Warrants, as well as those shares sold upon the exercise of Warrants, as directed by NASD. The ability of a holder of Common Stock purchased through the exercise of a Warrant to dispose of the economic interest in such stock is not affected by the Voting Trust. As of December 31, 2004, the 43,225,976 shares of Common Stock beneficially owned by NASD was composed of the following: o 21,570,408 shares of Common Stock that were subject to unexercised expired Warrants. Such shares were owned by NASD and not subject to the Voting Trust. NASD had sole dispositive and voting power over such shares. o 42,580 shares of Common Stock that were sold upon exercise of Warrants. As a consequence of the Voting Trust, NASD retains voting power over such shares until Exchange Registration, but has no economic interest in such shares. Dispositive power over such shares is held by their record holders. o 21,612,988 shares of Common Stock that are subject to unexercised unexpired Warrants. NASD may be deemed to have voting power over these shares until Exchange Registration through the Voting Trust, but does not have dispositive power over any of these shares until the applicable exercise period of the Warrants expires. 10,806,494 of these shares can be purchased by Warrant holders through the close of business on June 28, 2005, the date on which the third exercise period expires. The remaining 10,806,494 shares can be purchased by Warrant holders from June 29, 2005 through the close of business on June 28, 2006, the date on which the fourth exercise period expires. On February 9, 2005, NASD entered into an underwriting agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated and Credit Suisse First Boston LLC providing for the sale by NASD of 14,000,000 of the 21,570,408 shares of Common Stock that were subject to unexercised expired Warrants in a registered public offering. The underwriters also exercised their overallotment option to purchase from NASD an additional 2,586,980 shares pursuant to the underwriting agreement. The sale of these 16,586,980 shares is scheduled to close February 15, 2005. Item 5 Ownership of Five Percent or Less of a Class: Not Applicable Page 4 of 5 Pages
