Explanation of Responses:

Remarks:

After giving effect to the transactions reported hereby, National Association of Securities Dealers, Inc. ("NASD") has issued and outstanding 8,056,041 warrants ("Warrants"), each exercisable for one share of The Nasdaq Stock Market, Inc.'s ("Nasdaq") common stock, par value $0.01 per share (the "Common Stock"), held by NASD in each of four approximately one year consecutive exercise periods (the first, second and the third of which expired at the close of business on June 27, 2003, June 25, 2004 and June 27, 2005, respectively, and the fourth of which expires on June 27, 2006). Until Nasdaq is operating as an exchange, 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 directed by NASD. In addition, until the earlier to occur of the time Nasdaq satisfies conditions established by the Securities and Exchange Commission to operate as an exchange or the effectiveness of a registration statement filed by Nasdaq with the Securities and Exchange Commission with respect to the shares of Common Stock sold upon exercise of Warrants, the voting trustee will vote all such shares of Common Stock sold upon the exercise of Warrants, as directed by NASD (although NASD no longer has an economic interest in such shares). This Form 4 reflects the exercise of Warrants for the purchase of a total of 528,942 shares of Common Stock and the sale by NASD of such shares. After giving effect to the transactions reported hereby, NASD owns 8,056,041 shares of Common Stock underlying unexercised Warrants and thus subject to the Voting Trust.
