On April 21, 2005, The National Association of Securities Dealers, Inc. ("NASD") entered into a Stock Repurchase and Waiver Agreement with The Nasdaq Stock Market, Inc.

Nasdaq paid to NASD $39,999,994.93 in full consideration for the Shares of the Series C Preferred Stock. Immediately following the repurchase of the Shares of the Series C Preferred Stock, which was completed on April 22, 2005, NASD received from Nasdaq a new certificate representing the remaining 953,470 shares of the Series C Preferred Stock owned by NASD.
