LATHAM, N.Y. — Plug Power Inc. a leader in providing clean, reliable energy solutions, today announced it has been selected to provide 19 class 1 GenDrive fuel cell power units and two years of managed services for a demonstration project funded by the Department of Defense (DoD). Plug Power’s GenDrive units will be commissioned at the U.S. Army’s Forces Command in Fort Lewis, Washington where they will power a fleet of sit-down counterbalanced lift trucks.

The two-year project will study and assess the use of wastewater treatment plant digester gas as a hydrogen source for fuel cells. The hydrogen created will power the fuel cell forklifts used for heavy maintenance work at Fort Lewis.

Under the project, Plug Power will receive approximately $1.5 M in funding to supply 19 fuel cell units as well as expertise in system integration, training, service and support for 24 months. The GenDrive power units will be commissioned at Fort Lewis during the third quarter of 2010.

“When compared to lead acid batteries, Plug Power’s GenDrive fuel cells offer customers proven economic, operational and environmental benefits,” said Andy Marsh, CEO at Plug Power. “This Army site demonstration project will provide an opportunity to run our products under rigorous, real-world conditions, adding to the mounting evidence in support of the commercial viability of hydrogen fuel cells.”

Five industry leaders will partner on the project:

 -- The Center for Transportation and the Environment (CTE): overall
    project management and administration
 -- Plug Power Inc.: provide 19 GenDrive power units for use in
    electric lift truck fleet
 -- Air Products and Chemicals, Inc.: provide bulk hydrogen storage,
    compression and delivery
 -- Gas Technology Institute (GTI): supply a hydrogen generation
    reformer and gas clean up system for digester gas
 -- Proterra LLC: provide a fuel cell hybrid electric bus

This is the third in a series of Defense Logistics Agency (DLA) pilot projects that demonstrate the economic, operational and environmental benefits of powering material handling equipment with fuel cells. The projects intend to build a strong infrastructure for hydrogen delivery and refueling, while collecting the necessary data for a business case analysis.

MISSISSAUGA, ONTARIO– Hydrogenics Corporation a leading developer and manufacturer of hydrogen generation and fuel cell products, today announced that the Ontario Superior Court of Justice (the “Court”) has issued an interim order authorizing, among other things, the holding of a special meeting of the holders of common shares of Hydrogenics, at which such holders will be asked to approve the proposed arrangement (the “Arrangement”) in connection with the non-dilutive financing transaction to be implemented pursuant to a support agreement among Hydrogenics, the trustees of Algonquin Power Income Fund (”Algonquin Power”) and a newly created subsidiary of Hydrogenics (”New Hydrogenics”), which was announced on June 12, 2009.

Hydrogenics will hold a special meeting of shareholders at 10:00 a.m. (Toronto time), on July 27, 2009 at Hydrogenics’ head office at 5985 McLaughlin Road, Mississauga, Ontario, Canada. The record date for determining the holders of common shares of Hydrogenics entitled to receive notice of and to vote at the special meeting is June 23, 2009. At the special meeting, Hydrogenics shareholders will be asked to approve the Arrangement. For the Arrangement to be approved by the Hydrogenics shareholders, the resolution must be passed by at least 66 2/3% of the votes cast by shareholders, represented in person or by proxy, at the special meeting.

Pursuant to the Arrangement, Hydrogenics will transfer its business and operations, including substantially all of its assets and liabilities, excluding Hydrogenics’ tax attributes, to New Hydrogenics. New Hydrogenics will have substantially all of the same assets, liabilities, directors, management and employees as Hydrogenics has currently, except for certain tax attributes that will remain behind, and Hydrogenics shareholders will become shareholders of New Hydrogenics. Upon completion of the Arrangement, old Hydrogenics will be renamed “Algonquin Power Inc.” and New Hydrogenics will continue the Hydrogenics business as “Hydrogenics Corporation”.

The transaction also involves exchange offers pursuant to which unitholders and debentureholders of Algonquin Power will be offered to exchange their securities of Algonquin Power for new securities of Algonquin Power Inc., which will result in securityholders of Algonquin Power who accept the offers becoming securityholders of Algonquin Power Inc. and Algonquin Power becoming a subsidiary entity of Algonquin Power Inc.

The Arrangement is subject to final approval of the Court. Assuming that shareholders approve the Arrangement, Hydrogenics is expected to apply to the Court on July 29, 2009 (or as soon as possible thereafter) for a final order in respect of the Arrangement.

Hydrogenics’ proxy circular, as well as the related proxy form, are expected to be mailed to Hydrogenics shareholders on or about June 29, 2009.
