IBA Signs Term Sheet for the Disposal of Cisbio Bioassays SAS

Term sheet signed with European private equity firm valuing Cisbio Bioassays at approximately EUR 25 million

Louvain-la-Neuve, Belgium, May 14, 2013 - IBA (Ion Beam Applications S.A., EURONEXT), the world's leading provider of proton therapy solutions for the treatment of cancer, today announces the signature of a term sheet for the sale of its Business Unit Cisbio Bioassays SAS.

Following IBA's decision to refocus on its core businesses in radiation therapy (proton therapy, dosimetry) and accelerators for radiopharmaceuticals and industrial applications, IBA made the decision to dispose of its Bioassays division. IBA's Board held on May 8, 2013 has approved the signature of a term sheet with a European private equity firm. The projected value of the transaction is approximately EUR 25 million, a price close to the current book value of the Bioassays net assets in IBA's consolidated Financial Statement for 2012.

As per the term sheet, the Bioassays business will be sold to a new company in which IBA would keep a minority stake of approximately 15%. Financing will be secured by the seller through a vendor note for an amount of EUR 7.5 million, the closing of the transaction is therefore not subject to bank financing.

The current term sheet is non-binding and grants to the potential investor a period of exclusivity for the conduct of an extensive due diligence of the business.

Parties expect to close the transaction this summer.
