TORONTO, May 31, 2006 - Hummingbird Ltd. (NASDAQ: HUMC, TSX: HUM), a leading global provider of integrated enterprise content management (ECM) and network connectivity solutions today announced that it has notified The Texas Guaranteed Student Loan Corporation (TG) that a Hummingbird employee has lost a piece of computer equipment containing names and social security numbers of a portion of TG's customer base. The data was made available to Hummingbird as part of an ongoing engagement to customize and implement a document management system for TG.

TG is a public, nonprofit corporation that helps create access to higher education for millions of families and students through its role as an administrator of the Federal Family Education Loan Program.

Hummingbird has no reason to believe that the piece of equipment has been stolen to gain access to confidential data. The data was protected through security measures and given the technology that would be required to retrieve the data, Hummingbird believes that any misuse of the data is extremely unlikely. However, Hummingbird has exhausted every possibility to recover the equipment and has filed a lost property report with the police.

"The privacy of customer data is of utmost importance to us and we take our responsibility to safeguard it very seriously. We deeply regret that this incident has occurred," said Barry Litwin, President and CEO of Hummingbird Ltd. "We continue to investigate the facts surrounding this loss of information and are taking all necessary action in order to ensure that such occurrences do not happen in the future."

Even though Hummingbird believes that the accessibility and misuse of the information is highly unlikely, Hummingbird is providing its full cooperation to TG and supports TG's measures to protect its customers.

TG is providing information on its Web site at http://www.tgslc.org/resources/customerdata.cfm to help those potentially affected by this incident. In addition, TG will be mailing letters to individuals who were directly affected, with information about their records and recommendations on how to protect themselves from identity theft.
