9. Represents the acquisition of shares of common stock of the Issuer resulting from the vesting of performance shares awarded to the Reporting Person under the Euronext Executive Incentive Plan (the "Plan"). On June 6, 2007, the Issuer's Human Resources and Compensation Committee, consisting entirely of independent directors, voted to permit participants under the Plan, including the Reporting Person, to elect to accelerate the vesting of their awards made in 2005 at 100% of the target level of the award, or to continue to hold the same award subject to the terms of the Plan as amended on April 4, 2007 in connection with the combination of NYSE Group, Inc. and Euronext N.V. On the Transaction Date, the Reporting Person elected to accelerate the vesting of his 2005 award. The shares of common stock underlying the 2005 award are expected to be delivered on or about August 3, 2007, and will remain subject to transfer restrictions through December 31, 2007.
