In respect of the description of Eurex Group, a derivatives exchange business jointly owned by Deutsche Börse & SIX Swiss Ex...

Deutsche B�rse agreed with SIX Group AG to take over the Eurex joint venture and acquire the remaining participation in Eurex Zürich AG

On June 7, 2011, Deutsche B�rse signed a share purchase agreement (which is referred to herein as the “share purchase agreement”) with SIX Group AG and SIX Swiss Exchange AG, a wholly owned subsidiary of SIX Group AG, to purchase from SIX Group AG the remaining 50% shareholding in Eurex Zürich AG as well as the Swiss derivatives business relating to Eurex Zurich AG with economic effect as of January 1, 2012. Upon closing of the transaction and with economic effect as of January 1, 2012, Deutsche B�rse will receive 100% of Eurex’s economic interest instead of the 85% it is currently entitled to. The purchase price will be €590 million, 50% of which will consist of shares of Holdco that Deutsche B�rse will receive for the tender of Deutsche B�rse treasury shares in the exchange offer and 50% of which will consist of cash. If the conditions to completing the combination of Deutsche B�rse and NYSE Euronext have not been satisfied by March 31, 2012, Deutsche B�rse will pay to SIX Group AG 50% of the purchase price by delivery of Deutsche B�rse treasury shares and 50% of the purchase price in cash. For purposes of the purchase price, the Holdco shares (and the Deutsche B�rse shares, as the case may be) have been valued at the one-month volume weighted average price of a Deutsche B�rse share prior to the execution of the share purchase agreement.

The acquisition of the Eurex business by Deutsche B�rse is structured as a spin-off by SIX Swiss Exchange AG of the Swiss derivatives business regarding Eurex Zürich AG to a newly formed Swiss company (which is referred to herein as “Swiss NewCo”). The spin-off will include the shares in Eurex Zürich AG held by SIX Swiss Exchange AG, the rights to the Eurex system and the brand “Eurex” and other assets and contracts required for the current operation of the Swiss derivatives business and relating to Eurex Zürich AG. Assets and agreements held by SIX Swiss Exchange AG regarding the CHF Repo Market and the OTC Spot Market will not form a part of the spin-off. However, Eurex Zürich AG will continue to operate the CHF Repo Market and the OTC Spot Market following closing (with economic effect as from January 1, 2012 for its own account) based on continued business management agreements (Geschäftsbesorgungsverträge) and license agreements. Following the spin-off, all shares in Swiss NewCo will be acquired by Deutsche B�rse. Through the acquisition of these shares in Swiss NewCo, Deutsche B�rse will become sole indirect shareholder of Eurex Zürich AG and will carry on the business activities of Eurex in Germany and Switzerland.

Following the closing of the Eurex transaction, the shareholders’ agreement dated August 31, 1998 between Deutsche B�rse and SIX Swiss Exchange AG, the Investment Protection Agreements relating to International Securities Exchange (ISE) and European Energy Exchange (EEX), the operating agreement (Betriebsführungsvertrag) between SIX Swiss Exchange and Eurex Zürich AG and the letters of comfort issued by SIX Swiss Exchange AG in favor of Eurex Clearing AG, as well as a number of other agreements that have been entered into by the parties in relation to the Eurex joint venture, will be terminated or transferred to Swiss NewCo.

SIX Group AG and SIX Swiss Exchange AG have agreed in the share purchase agreement that neither they nor their affiliated companies will engage directly or indirectly in competition with Eurex regarding the derivatives business, as it is presently operated by Eurex, for a term of two years after the closing of the Eurex transaction. In turn, Deutsche B�rse has agreed to continue the business of Eurex Zürich AG, largely as it currently stands (including the CHF Repo Market and the OTC Spot Market) and with a competitive operating platform, for at least three years from closing of the Eurex transaction.

Other areas of cooperation between Deutsche B�rse and SIX Group, such as STOXX and Scoach, will not be affected by the share purchase agreement. However, the parties agreed to commence non-binding discussions for the purpose of evaluating other co-operations after the closing.

The closing of the Eurex transaction is subject to, among other approvals, antitrust approvals, other regulatory approvals, if required, and either the completion of the combination of Deutsche B�rse and NYSE Euronext or the occurrence of March 31, 2012. If, at March 31, 2012, the settlement of Holdco’s exchange offer for Deutsche B�rse shares (i.e. , the delivery of HoldCo shares for tendered Deutsche B�rse shares) has not been completed, but all conditions to completing the combination between Deutsche B�rse and NYSE Euronext have been satisfied, then Deutsche B�rse’s obligation to pay the share portion of the consideration in Holdco shares will be extended until April 15, 2012. After such time, assuming completion of all other conditions under the share purchase agreement, the share portion of the transaction consideration will be made in Deutsche B�rse shares. If the closing conditions to the share purchase agreement are not satisfied by June 30, 2012, either party may withdraw from the share purchase agreement.
