Thales submits proposal to acquire nCipher Neuilly-sur-Seine, 11 July 2008 Thales and nCipher are pleased to announce that they have reached agreement on the terms of a recommended cash offer to be made by Thales UK, a wholly owned subsidiary of Thales, for the entire issued share capital of nCipher PLC (NCH.L). Under the terms of the Offer, nCipher shareholders will receive 300 pence in cash for each nCipher share. Accordingly, as at 10 July 2008, the Offer values nCipher at approximately £50.7 million. nCipher, based in Cambridge, UK, is a leading supplier of encryption products for organizations that need to protect sensitive data. nCipher is delivering solutions in the fields of key management and cryptographic hardware. nCipher operates largely in the UK and the US, with customers including governments, financial institutions, and public and private enterprises.

Combined technological strengths, a diverse product portfolio, strong brand leadership, and a global institutional customer base, will provide expanded opportunities for customers and employees. Commenting on the Offer, Alex Dorrian, CEO of Thales UK, said: “The acquisition of nCipher will bring together the best practices of both businesses in order to provide our customers with an enlarged security product range and a more complete suite of security services across the data encryption industry.
