Joint Development and Production Agreement

Acta S.p.A.

("Acta" or "the Company")

Joint Development and Production Agreement with MES S.A.

Acta S.p.A. (AIM:ACTA), the clean energy products company, is pleased to announce that it has signed a joint development and production agreement ("Agreement") with MES S.A. ("MES"), for the production of 250-500W portable power generators for use in marine and recreational vehicle applications. MES, founded in Switzerland in 1976, is a world leader in the research, development and manufacturing of electric components for automotive and household appliances, with distribution in Europe, USA, China and Brazil who currently produces fuel cell components and systems from 500W up to 3kW.

Under the terms of the Agreement the parties will jointly develop and then produce portable power generators with a power output of 250-500W, four hours duration at maximum power and AC/DC output. Marine versions of the power generators incorporating filters for sea air will also be developed.

The portable power generators will be targeted at the nautical (electrical outboard engines) and recreational vehicle markets, at a price of c.€2,500 to €3,500 plus VAT per unit. A small volume product launch is expected to commence in Autumn 2011, with large scale production facilities planned for mid 2012. The market size in the first year following launch is estimated to be in the region of 500 to 1,000 units per year, with significant growth thereafter.

About Acta S.p.A.

Acta S.p.A. is a developer and manufacturer of a range of clean energy products. Its product line includes market-leading compact hydrogen generators (electrolysers) which produce pure, dry and compressed hydrogen in a way that is easy-to-use and completely safe. The Company is also extensively involved in the Italian solar photovoltaic market through its photovoltaic business, ActaSol, and is committed to integrating its award-winning electrolysers with renewable energy sources. The Company is currently in the process of delivering a significant photovoltaic installation contract to SPF Energy through its joint venture company, SolGen, and is developing a substantial pipeline of project consents.

Acta's cost-competitive electrolysers are based on its proprietary, inexpensive environmental catalyst and hydrogen conversion technologies. These products help overcome the barriers to the adoption of fuel cells, most notably the lack of a local hydrogen infrastructure. Acta has exploited these technologies to develop onboard automotive hydrogen generation systems for diesel enrichment, reducing diesel consumption and pollution emissions.

Acta's low-cost hydrogen generators represent a unique breakthrough in electrolyser technology. They can operate using mains power or intermittent renewable energy, and produce clean, dry hydrogen already at pressure for use in fuel cell and other applications. This unique combination of features avoids the system complexity and energy cost of further cleaning, drying and compression of the hydrogen, resulting in a simple, compact, low-cost and highly efficient system that is ideally suited for energy conversion and storage applications. In such applications, which include battery replacement and renewable energy storage, low cost and high efficiency are critical to commercial viability, while hydrogen compression is essential for the energy density of the system. No other water electrolyser currently on the market offers this combination of benefits.

Acta is focusing on delivering its products to markets with high volume demand for high-value environmental solutions (transport, UPS, energy and leisure). It is accelerating the commercialisation of its products via partnerships with original equipment manufacturers (OEMs), distributors, and agents in these sectors, and intends to drive down production costs at high volume via contract manufacturing.

Acta is marketing its electrolyser product range to early adopters through its energy products division, Acta Energy. This division's objective is to ensure, through facilitating the widespread adoption of commercial and domestic fuel cell products, that Acta's hydrogen generator becomes a familiar industrial and domestic appliance.

Acta S.p.A. is based near Pisa, Italy, and was admitted to trading on AIM in October 2005.
