NASDAQ OBTAINS CLEARANCE FROM THE COMMITTEE ON FOREIGN INVESTMENT IN THE UNITED STATES

PLANS FOR PROPOSED ACQUISITION OF OMX AB ON TRACK

NASDAQ FORMALLY WITHDRAWS STAND-ALONE OFFER FOR OMX, WILL PROCEED WITH ACQUISITION OF OMX FROM BORSE DUBAI

New York, NY, December 31, 2007 -- The Nasdaq Stock Market, Inc. (Nasdaq: NDAQ) today announced that it has obtained clearance from The Committee on Foreign Investment in the United States (CFIUS) concerning Borse Dubai’s investment in NASDAQ, which will allow it to proceed with its plans to combine with Stockholm-based OMX AB (publ) (OMX). NASDAQ and Borse Dubai Limited (Borse Dubai) had previously voluntarily submitted their agreement to CFIUS for review.

As a result of CFIUS approval, NASDAQ said today that as part of its transaction with Borse Dubai, announced on September 20, 2007, it has formally withdrawn its offer for OMX and supports Borse Dubai’s all cash offer of SEK 265 per share to acquire OMX. All other previously agreed conditions for Borse Dubai to open its offer have now been fulfilled or waived in accordance with the agreements between Borse Dubai and NASDAQ.
Provided Borse Dubai owns in total at least 67% of the shares of OMX and the conditions for closing the transaction under the agreement with NASDAQ have been satisfied or waived, Borse Dubai will sell all OMX shares it owns to NASDAQ for consideration in NASDAQ shares and cash, as previously announced. At the same time, NASDAQ will make an investment in Dubai International Financial Exchange, as previously announced.

NASDAQ’s now-withdrawn stand-alone offer for OMX was conditional upon being accepted to such an extent that NASDAQ becomes the owner of shares representing more than 90 percent of the outstanding shares in OMX on a fully diluted basis(Condition number 1 in NASDAQ’s announcement of the NASDAQ offer from May 25, 2007.). Borse Dubai will open its offer for OMX for acceptances when the offer document has been approved by relevant authorities.

Taking into account that Borse Dubai today, before the opening of its offer, controls shares, options and irrevocable undertakings which will result in Borse Dubai holding approximately 48.3 percent of OMX's issued share capital and votes when the options and irrevocable undertakings are exercised in accordance with what has previously been announced, it is clear that the 90 percent acceptance condition in NASDAQ's stand-alone offer cannot be fulfilled.

NASDAQ therefore announces today that it withdraws its stand-alone offer for OMX, in accordance with the agreements with Borse Dubai and as presented in statement AMN 2007:32 from the Swedish Securities Council.
