->DISCLAIMER

The communication on this website does not constitute an offer to sell or to purchase securities, nor a solicitation of an offer to sell or to purchase securities, whether in the context of the public tender offer in Switzerland by SCOR on the shares of Converium Holding AG ("Converium") with a nominal value of CHF 5 each (the "Tender Offer") or otherwise in France or in any jurisdiction where such offer, solicitation, sale or the acceptance of such offer may be unlawful. It does also not constitute a recommendation to sell or buy shares in SCOR or Converium.

The Offer Prospectus (the "Offer Prospectus") contains the terms and conditions of the Tender Offer, including the scope of the Offer, the way the Tender Offer can be accepted and the restrictions applicable to the Tender Offer in some countries. The Tender Offer is subject to all the terms and conditions set forth in the Offer Prospectus.

The Tender Offer made to the shareholders of Converium and the Offer Prospectus which has been filed with the Swiss Take Over Board and published on Bloomberg and in Le Temps and Neue Zürcher Zeitung in Switzerland on April 5, 2007 have been exclusively prepared under Swiss law and are subject to review and supervision by Swiss authorities only. The Tender Offer is not subject to any formality, registration or approval outside Switzerland (except for the share offering circular (the "Admission Prospectus") for the new SCOR shares to be issued in consideration to Converium shareholders’ contributions of their shares to the Tender Offer). The Tender Offer will not be made and may not be accepted in any jurisdiction where it breaches applicable law or where the applicable law requires SCOR in any way to change the Tender Offer, to submit an additional application to any authorities or other institutions, or to take any additional actions in connection with the Tender Offer (including, without limitation, Japan). SCOR shall not accept and shall have no obligation to accept any tenders made in connection with the Tender Offer from any such jurisdiction. It is not intended to extend the Tender Offer to any such jurisdictions. Documents related to the Tender Offer may neither be distributed in nor sent into such jurisdictions. Such documents do not constitute and may not be used to solicit an offer to sell or to purchase securities by any persons in such jurisdictions. In addition, the delivery of the new SCOR shares may be subject, in certain jurisdictions, to specific regulations or restrictions. The Tender Offer is not addressed to persons subject to such restrictions, either directly or indirectly. Persons in possession of the Offer Prospectus or any other document relating to the Tender Offer are required to obtain information about any local restriction that may apply and comply therewith. SCOR disclaims any liability for any violation of any applicable restrictions by any person.

The Admission Prospectus regarding the new SCOR shares to be issued in consideration to Converium shareholders’ contributions of their shares to the Tender Offer and a document established envisaging SCOR’s shareholders’ meeting convened to approve the contributions by Patinex AG and by Alecta pensionsförsäkring, ömsesidigt of their Converium shares (the "Document E") has each been registered with the French Autorité des Marchés Financiers (the "AMF") on April 10, 2007. The Admission Prospectus and the Document E are available without charges at SCOR’s corporate headquarters, 1, avenue du Général de Gaulle, 92 800 Puteaux, France, on SCOR’s website and on the AMF’s website.
