Swedish Securities Council Grants Extension Regarding Offer Document Requirement

Stockholm, August 3, 2007 -- The Nasdaq Stock Market, Inc. (“NASDAQ”) and OMX AB (publ) (“OMX”) announced on May 25th 2007 that they had entered into an agreement to combine the two companies, creating the world’s premier exchange and technology company.
The combination will be effected through a cash and stock tender offer for all outstanding shares in OMX.

NASDAQ has applied to The Swedish Securities Council for an additional 10-week extension to the requirement that an offer document shall be prepared within four weeks from the day the public offer was announced. The Swedish Securities Council has now granted such an extension in its ruling AMN 2007:26. This extension is consistent with the previously stated timetable of a fourth quarter completion of the public offer.
