Revoking Your Proxy If you are a CSLM shareholder and you give a proxy, you may revoke it at any time before it is exercised by doing any one of the following:

| • |     | you may send another proxy card with a later date; |

| • |     | you may notify Charles Cassel, Chairman of CSLM, in writing before the extraordinary general meeting that you 
 have revoked your proxy; or                                                                                   |

| • |     | you may attend the extraordinary general meeting, revoke your proxy, and vote, as indicated above. |

If your shares are held in “street name” or are in a margin or similar account, you should contact your broker for information on how to change or revoke your voting instructions.
