Therefore, persons obtaining any Offer Documentation or into whose possession any Offer Documentation otherwise comes, are required to, and should inform themselves of and observe, all such restrictions. Neither GAM Holding AG nor Liontrust Asset Management Plc nor the receiving agent accept or assume any responsibility or liability for any violation by any person whomsoever of any such restriction.

The Offer Documentation should not be sent or otherwise distributed in or into the Restricted Jurisdictions and the Offer cannot be accepted by any such use, means or instrumentality, in or from within the Restricted Jurisdictions. Accordingly, copies of the Offer Documentation are not being, and must not be, sent or otherwise distributed in or into or from any Restricted Jurisdiction or, in their capacities as such, to custodians, trustees or nominees holding shares for persons in any Restricted Jurisdictions, and persons receiving any such Offer Documentation (including custodians, nominees and trustees) must not distribute or send them in, into or from any Restricted Jurisdiction. Any purported acceptance of the Offer resulting directly or indirectly from a violation of these restrictions will be invalid. No shares are being solicited in the Offer for purchase or sale from or to a resident of the Restricted Jurisdictions and, if sent in response by a resident of the Restricted Jurisdictions, Liontrust Asset Management Plc reserves the right to reject such acceptance. Such Offer Documentation must not be used for the purpose of soliciting the purchase or sale or exchange of any shares in GAM Holding AG (the "GAM Shares") or shares in Liontrust Asset Management Plc (the "Liontrust Shares") by any person or entity resident or incorporated in any Restricted Jurisdiction.
