The results of the stockholder vote were certified by Broadridge Financial Solutions, Inc. �Our affirmative stockholder vote is a significant milestone as ISE and Eurex move forward to combine our two businesses to create the leading transatlantic derivatives marketplace,� said David Krell, ISE President and CEO. �We are very pleased that our stockholders support this combination, which is an important strategic step to grow ISE�s business in the years ahead. Currently, we are continuing with the necessary steps to complete this transaction as promptly as possible so that we can move forward to the integration phase.� Andreas Preuss, CEO of Eurex and a member of the executive board of Deutsche B�rse said, �The result of today�s extraordinary general meeting marks an important step towards the anticipated creation of a market leader in individual equity, equity index and long-term interest rate derivatives worldwide. We are confident that this partnership will significantly enhance our global position in the derivatives markets. It will enable ISE and Eurex to offer trading efficiencies and access to a global product suite to our respective exchange members. After the transaction closes, we plan to integrate the two businesses as promptly as possible to deliver additional value to our shareholders and customers.� The transaction will create the leading transatlantic derivatives marketplace with significant USD and Euro product coverage and with significant operations and revenues in both the U.S. and Europe. Overall trading volume for the combined entity was 2.1 billion contracts in 2006. Eurex�s and ISE�s complementary member bases and product portfolios provide substantial growth opportunities across asset classes and national boundaries. The affirmative stockholder vote satisfies a condition to the closing of the acquisition. The transaction also requires SEC approval.
