Lonza acquires amaxa, a technology leader in cell discovery

• amaxa excellent fit with Lonza Bioscience Cell Discovery business

• Strengthening of both businesses with accelerated growth potential

• In line with Lonza strategy of growing its life-sciences-platform

Basel, 27 May 2008 – Lonza and amaxa jointly announce that Lonza, the leading supplier to the life sciences industries, acquires amaxa and all its activities. The transaction is financed with proceeds from recent divestitures. Financial details remain confidential at this time. amaxa is a premium supplier to the cell discovery market with leading edge, proprietary technologies in well defined market niches of transfection systems. The deal will enhance current margins and growth rates of Lonza Bioscience. The transaction is subject to the approval of the anti-trust authorities, which is expected to take place early in Q3 2008.

amaxa will significantly strenghthen the Cell Discovery business of Lonza Bioscience by complementing and expanding the existing portfolio. amaxa offers high-end nucleic acid transfection systems and consumables to academic institutions and pharmaceutical and biotechnology businesses. The company provides a leading and unique technology called Nucleofection, which addresses critical industry needs in Cell Discovery. amaxa’s Nucleofection technology is a transfection method which enables efficient and reproducible transfer of nucleic acids such as DNA or RNA into cells that are considered difficult or even impossible to transfect.

In addition the acquisition of amaxa will strengthen the R&D platform for Lonza Bioscience, by tripling the size of the cell discovery R&D group. amaxa’s Cologne site is planned to be a new product development site for the Cell Discovery business of Lonza Bioscience and will supplement the existing R&D activities of Lonza’s cell discovery business in Walkersville, MD, USA. With the strong foothold of amaxa in Germany, Lonza gains access to the large Northern Europe talent pool.

Stefan Borgas, Chief Executive Officer of Lonza, comments: “We are excited to welcome the highly qualified and entrepreneurial amaxa colleagues to join our global business. With this acquisition Lonza further strengthens its position as a worldwide leader in cell discovery by integrating this unique, proprietary technology into its portfolio and by continuing to develop the actvities in Cologne. We are pleased to be able to offer this technology and product line to our customers. The acquisition of amaxa is in line with our strategy of re-deploying cash from our divestitures into well defined growth opportunities for our life-sciences-businesses.”

Lonza’s and amaxa’s Cell Discovery business are complementary, serving a similar customer base. While Lonza is the leader in the production of primary cells, amaxa is the leader in the transfection of primary cells. Customers can now get all their primary cell tools through one company. Other synergies are expected through the strengthening of the sales force and the integration of amaxa’s administrative and enterprise systems into Lonza’s infrastructure.

Rainer Christine, Chief Executive Officer of amaxa adds: “The integration of our business into Lonza will help to further expand the use of our unique transfection technology. The reputation and strategic focus of Lonza as a leading supplier to the life sciences industries enables the broadening of our customer base and will allow further development of the technology and its applications. Further, the shared spirit of entrepreneurialism, passion, and customer orientation provide a strong platform for beginning the integration process.”

To ensure that our customers, employees, and shareholders gain the value from this transaction, an integration process has been developed and a team of fully dedicated employees from both Lonza and amaxa will be responsible for a systematic implementation.
