Agreement with Heliocentris

Acta S.p.A.

("Acta" or "the Company")

Strategic Commercial Partnership with Heliocentris including

Licensing Agreement and Investment

Acta S.p.A. (AIM: ACTA), the clean energy products company, announces that it has entered into a ten year licensing agreement (the "Agreement") with Heliocentris Energy Solutions AG (XETRA: H2FA) ("Heliocentris"), a company which specialises in autonomous energy supply and energy efficiency solutions with the aim of replacing diesel generators with "zero-emission" products.

Under the Agreement Heliocentris has committed to buying alkaline solid membrane electrolyser products exclusively from Acta, with a minimum purchase commitment of 500 units in the third year of the partnership and €1.5 million in year four. In exchange Heliocentris will have a non exclusive world-wide license to use Acta's technology in all Heliocentris products, and subject to meeting the above minimum purchase commitments, will maintain exclusive licenses in Germany and for Middle East and Africa for certain stationary clean power applications such as telecom base stations or home power solutions, as well as the world-wide exclusive license for certain laboratory, educational and training applications. Acta will continue to establish commercial partnerships for its hydrogen generator products in other markets and applications world-wide.

The Agreement is conditional on an investment of €250,000 by Heliocentris in any equity fundraising by Acta of over GBP 1.8 million and Heliocentris have indicated an investment price of up to 6 pence per share. As announced on 14 February 2012 Acta has decided to seek additional funds to finance the working capital requirements of the Company's current commercial expansion and subject to receiving the required shareholder authority at the EGM to be held on 1 March 2012, it is expected that this will be by way of an equity fundraising.

Paolo Bert, Chief Executive of Acta commented

"Heliocentris is a world leader in the field of energy efficiency and clean power solutions and as such, this Agreement represents not only a fantastic endorsement of Acta's technology, but also the culmination of many months of successful product validation. It will enable Acta to address significant markets for its products through the established sales channels which Heliocentris already has in place.

In particular we expect to gain rapid market traction in the Middle East, where Heliocentris has the benefit of established local operations, the presence of NTEC, the technology arm of the Kuwait Investment Authority and a close connection to Alcazar Capital, a Dubai-based corporate finance advisory and private equity firm with a strong focus on the telecoms industry. In addition, the investment by Heliocentris in Acta demonstrates the confidence in the collaboration and the progress the two companies have made to date."

Ayad Abul-Ella, Chief Executive of Heliocentris commented

"We are excited to have entered into this strategic partnership with Acta. Cost efficient and scalable hydrogen generation is an important element of Heliocentris' roadmap towards autonomous power and zero emission solutions. The combination of Acta's innovative alkaline solid membrane technology and Heliocentris' leading system engineering know-how will enable Heliocentris to expand its successful current rollout of GenSet efficiency and energy management solutions to the next level: commercially viable and industrial grade autonomous power as well as zero emission solutions."

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, and the Company is committed to integrating its award-winning electrolysers with renewable energy sources.

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'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, back-up power, 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 S.p.A. is based near Pisa, Italy, and was admitted to trading on AIM in October 2005.
