NANTES, FRANCE--(Marketwire - June 23, 2010) - VIVALIS (NYSE Euronext: VLS), a biopharmaceutical company, announced today that its research and development teams have moved into its new facility in Saint-Herblain Nantes, France.

This new 3,300 m² (35,520 ft2) facility is dedicated to R&D activities and support functions. The project was initiated at the end of 2008 and integrates all research teams onto the same site, which is adjacent to Vivalis' existing 1,500 m² (16,150 ft2) cGMP bioproduction facility, completed in 2005.

The new building houses state-of-the-art equipment used for biologics research and the construction has been governed by an environmentally responsible approach, being designed to use 25% less energy than our current bioproduction facility completed five years ago. With a total investment of 6.5M€ as budgeted (5.5M€ for the facility and approximately 1M€ for equipment), the facility was financed by state and local entities (DIACT, Region Pays de Loire, Departement of Loire Atlantique and Nantes Métropole for a total of 2.4M€), bank loans (2.5M€) and VIVALIS (1.6M€).

With this new facility VIVALIS will be able to accelerate its development projects while improving the working environment and conditions of its employees.

"We are very pleased to move into these new facilities that give us the ability to regroup the teams that were spread over several locations following the rapid expansion of our workforce. We are very proud of being able to offer our researchers optimal conditions to conduct their research. We now have two locations in Nantes totaling over 4,800 m² (51,700 ft2) located on one site and dedicated to research and biomanufacturing," said Franck Grimaud, CEO, and Majid Mehtali, CSO, co-managers of VIVALIS.
