Sofinnova Partners, Gimv and Amundi Private Equity Funds Invest in McPhy Energy

EUR 13.7m Second Round Funding

PARIS, July 1, 2010 - Sofinnova Partners, acting as a leading investor, Gimv and
Amundi Private Equity Funds announced today their investment in McPhy Energy,
together with the historic investors in a second round of funding worth
EUR 13.7m. The funds will be used towards the global expansion of McPhy
Energy and the further industrialisation and commercialisation of its
products.

McPhy Energy is an innovative French company founded in
January 2008 with the mission to industrialise and commercialise a new
technology for the solid storage of hydrogen in the form of magnesium
hydride. The company has developed an alternative solution for the on-site
production of hydrogen for the industry sector and for the renewable energy
sector a concrete solution to solve the issue of energy storage.

Following a EUR 1.6m first round of financing in January 2009
from Emertec and Areva, the firm established its production line and created
a reservoir of magnesium hydride that was delivered to CEA-Liten in March
2010 for testing on an industrial scale. The company is now developing a
second large-capacity reservoir that will become operational during the
second half of 2010.

The second round of funds will allow the start-up to scale
quickly, from both an industrial and commercial development point of view, by
reinforcing its commercial and technical team and investing in additional
production equipment. Already present in Spain and in Italy, the company also
plans to open offices in Germany, Northern Europe, the Middle East and Japan.

"Through our innovative and very promising technology, McPhy
Energy offers a new perspective on technical, ecological and economical
solutions in the areas of industrial hydrogen distribution and energy
storage," explains Pascal Mauberger, CEO of McPhy Energy. "We are proud that
such experienced investors share our enthusiasm for McPhy Energy's advanced
technology and will accompany us in further developing critical alternatives
in these two fields," he added.

"Following past investments in DNP Green, Revolt Technology
and Neosens, this latest investment in McPhy Energy is proof of Sofinnova
Partners' continued interest in the Cleantech sector," says Alessio Beverina,
Principal at Sofinnova Partners. "McPhy Energy exemplifies what we actively
seek in a start-up: an innovative technology that solves an unanswered issue
in a growing international market and, above all, a high-quality managerial
team which has already successfully proven itself and demonstrated its
entrepreneurial spirit."

"Over the past two years, McPhy Energy has finalised its
unique hydrogen storage technology. It is now ready to enter several
promising market segments. We are convinced that solid state hydrogen storage
will be one of the winning solutions to address the growing need for green
and large-scale energy storage," says Bart Diels, Partner at Gimv. "McPhy
Energy signifies our first Cleantech deal in France, where Gimv already
concluded two other venture capital transactions in the past twelve months."

"McPhy Energy represents a great opportunity to continue the development
of our activity and expertise in the Cleantech sector," explains Florent
Thomann, Investment Manager at Amundi PEF. "The powerful, breakthrough
technology, an advanced industrial product on the brink of market launch,
combined with an experienced and complementary management team and a huge
market potential convinced us to accompany McPhy. Its unique product offering
will enable McPhy not only to make industrial hydrogen use easy, but to solve
one of today's major problems : the storage of energy," he added.

Clipperton Finance acted as Sole Manager of the transaction.
"We are very proud to have been able to advise the company and its management
through this critical phase of McPhy's development, and very confident that
the company's syndicate of experienced investors will be instrumental for its
success," commented Nicolas von Bulow and Thomas Neveux, the Partners at
Clipperton Finance in charge of the operation.
