Correction: Contract for 1MW Solar Installation

Acta S.p.A.

("Acta" or "the Company")

Correction: €3.5 million Contract for Further 1MW Solar Installation

The following amendments have been made to RNS number 7598T released at 07.00 on 4 October, 2010. Previously, it was noted that:

- "Tesla S.r.l. is owned by the Radaelli family, third-generation textile industrialists producing prestigious velvet and silk products in Lecco, central Italy (www.redaellivelluti.it)."

Following clarification that there is no financial or other connection between Tesla S.r.l. and the company Redaelli Velluti S.p.A., this has now been replaced with:

- "Tesla S.r.l. is owned by a collection of private investors from the Lombardia region of Northern Italy."

The revised announcement is set out below:

Acta S.p.A. (AIM:ACTA), the clean energy products company, is delighted to announce the signing of a new solar photovoltaic ('PV') installation agreement with Tesla S.r.l., an investment company newly formed for the purpose of this transaction and entirely focused on the Italian renewable energy sector.

Under the EPC (Engineering, Procurement and Construction) Contract, signed on 1 October 2010, Acta will install a 1MW photovoltaic park in the Abruzzo region of central Italy, fulfilling a project authorisation consent which has been developed by Acta's PV pipeline development team (as announced in August 2010 following receipt of project approval). The contract is subject to confirmation of the transfer of land lease rights to Tesla, expected to occur on or around 12 October 2010. Installation of the €3.5 million project is scheduled to be completed by the end of 2010.

The EPC contract has been signed by ActaSol S.r.l., Acta's 100% subsidiary, through which the Company is managing its photovoltaic business activities. The appointment of ActaSol as main EPC contractor represents a significant step forward for the Group, and reflects the acceptance of ActaSol as a "bankable" EPC contractor on the part of the bank which has approved the terms of financing to Tesla for the project.

Tesla S.r.l. is owned by a collection of private investors from the Lombardia region of Northern Italy.

Paolo Bert, Chief Executive, commented:

"We are particularly pleased to have signed the agreement with Tesla Srl as it demonstrates Acta's ability to sell project authorisations developed from inception by our own team. In addition, our subsidiary ActaSol has now been approved as EPC main contractor by a leading Italian credit institution. This combination of achievements, following on from the acquisition transaction announced on 22 September 2010, has given Acta a range of in-house capabilities that now stretch from project development and authorisation through to project implementation and final connection. We are one of the few participants in the Italian PV sector able to offer such a range of services.

"This additional 1MW, €3.5 million contract marks our continued development in solar PV and further endorses our decision to invest in the sector which, thanks to an enlightened Government approach, remains buoyant in Italy."

Notes to Editor

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 €32.2m (10.6MW) installation contract to SPF Energy through its joint venture company, SolGen, and is developing authorisation approvals for a 25 MW project pipeline.

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, 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.
