Dear Sirs,

Project Gamma – Amendment Agreement to Sale Agreement

We refer to the Share Exchange and Purchase Agreement relating to the exchange, sale and purchase of shares in Chi-X Europe Limited dated 18 February 2011 and entered into between ourselves and the entities to whom this letter is addressed (the “Sale Agreement”). Capitalised terms used but not defined in this Amendment Agreement shall, unless the context dictates otherwise, have the same meaning as is given to them in the Sale Agreement.

Under clause 3.1, and paragraph 2.1 of Schedule 2 to the Sale Agreement (as originally drafted), the exchange, sale and purchase of Shares pursuant to the Sale Agreement are in all respects conditional upon, amongst other things, the OFT Condition having been fulfilled or (where expressed to be capable of being waived) waived. Following the referral of the purchase of the Company by the Purchasers to the Competition Commission and the agreement by the parties to seek to proceed with the transaction contemplated by the Sale Agreement, we now seek to confirm our agreement regarding certain matters relating to, and certain amendments which are to be made to, the Sale Agreement as set out in this Amendment Agreement.
