Hydrogenics Provides Update on NASDAQ Trading Status

Hydrogenics Corporation (Nasdaq:HYGSD) (TSX: HYG) ("Hydrogenics" or the "Company") a leading developer and manufacturer of hydrogen generation and fuel cell products, today announced that, as expected, the Company received a staff determination letter from the NASDAQ Stock Market ("NASDAQ") notifying the Company that its common shares are subject to delisting from the NASDAQ Global Market based upon the fact that Hydrogenics' stock has not satisfied the $1.00 minimum bid price requirement under Listing Rule 5450(a)(1) (the "Minimum Bid Price Rule") for ten consecutive trading days.

The Company intends to request a hearing with the NASDAQ to appeal the proposed delisting. Subsequent to the previously announced one-for-25 consolidation of the Company's common shares, effective March 12, 2010, the Company's common shares have traded above the $1.00 Minimum Bid Price requirement. Once the common shares have traded at or above $1.00 per share for ten consecutive trading days, which the Company expects will occur beginning March 26, 2010, the Company will be in full compliance with the Minimum Bid Price Rule and the delisting proceedings should be terminated. 

Separately, Hydrogenics shares will trade under the symbol "HYGSD" for 20 business days following the share consolidation, or until April 9, 2010, subsequent to which the shares will revert to trading as "HYGS."
