HYG iShares iBoxx Dollar High Yield Corporate Bond

Hydrogenics Corporation (Nasdaq:HYGS) (TSX:HYG), a leading developer and manufacturer of hydrogen generation and hydrogen-based power modules, today announced that it has filed a preliminary short form base shelf prospectus with certain Canadian securities regulatory authorities and a corresponding registration statement on Form F-10 with the U.S. Securities and Exchange Commission. After the base shelf prospectus becomes final and the registration statement is declared effective, Hydrogenics will be able to offer, from time to time over a 25-month period, up to US$100,000,000 of debt, equity and other securities.

The new base shelf prospectus and corresponding registration statement on Form F-10 will replace Hydrogenics' current US$25,000,000 base shelf prospectus and corresponding registration statement on Form F-3. The new base shelf prospectus should provide Hydrogenics with greater flexibility to access the capital markets.

Should Hydrogenics offer any securities, it will make a prospectus supplement available that will include the specific terms of the securities being offered and use of net proceeds derived from the offering.

Hydrogenics is not required to offer or sell all or any portion of the securities in the future and will only do so if market conditions warrant.

A receipt for the final short form base shelf prospectus has not yet been obtained from the Canadian securities regulatory authorities and the registration statement on Form F-10 has not become effective. Prior to the time a receipt is issued by the Canadian securities regulatory authorities for the final short form base prospectus and the shelf registration statement becomes effective, no securities may be sold, nor may offers to buy be accepted, pursuant to these documents. This press release does not constitute an offer to sell or the solicitation of an offer to buy any securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.

A copy of the shelf registration statement, including the related prospectus, may be obtained from Hydrogenics by submitting a request to Investor Relations at 220 Admiral Boulevard, Mississauga, Ontario L5T 2N6, by telephone at (905) 361-3660 or by email at investors@hydrogenics.com or on the SEC's website at www.sec.gov.
