On June 19, 2009, NYSE Euronext, a Delaware corporation ("NYX"), entered into an amendment (the "Amendment") to the Shareholders' Agreement dated June 24, 2008 (the "Shareholders' Agreement") with Qatar Holding ("QH"), the strategic and direct investment arm of Qatar Investment Authority, a Qatar governmental entity ("QIA"). The amended Shareholders' Agreement represents a strategic partnership between NYX and the State of Qatar to establish the Qatar Exchange (the successor to the Doha Securities Market ("DSM")).

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Shareholders Agreement and the Amendment, which is attached to this Current Report on Form 8-K as Exhibit 10.1. The Shareholders' Agreement was attached as exhibit 10.5 to NYX's Form 10-Q for the fiscal quarter ended June 30, 2008 which was filed on August 13, 2008.

The Qatar Exchange, as the successor to the DSM, will continue to provide a market for cash equities, and the aim of management is also to create a new derivatives market. NYX has agreed to contribute US$200 million in cash to acquire a 20% ownership interest in the Qatar Exchange. As previously announced by NYX, US$40 million of the US$200 million investment was paid upon closing on June 19, 2009 and generally, the remaining US$160 million is to be paid in four equal installments on each of the next four anniversaries of the closing date. QIA will retain the remaining 80% ownership of the Qatar Exchange through QH, and the current DSM, including approximately US$200 million in cash, will be transferred to the new Qatar Exchange.

In addition, the Qatar Exchange will adopt the latest NYX trading and network technologies and NYX will provide certain management services to the Qatar Exchange at negotiated rates.

Further, on June 19, 2009, NYX and QH issued a joint press release announcing the signing of formal terms of the strategic partnership and jointly participated in a press briefing. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1.
