Discovery Air secures contract with Enbridge

May 25, 2010, Yellowknife – Discovery Air Inc. is pleased to announce
that its Great Slave Helicopters (GSH) subsidiary has been awarded a
contract to provide helicopter services to Enbridge Pipelines NW Inc.
(Enbridge), operator of the liquids pipeline running between Norman
Wells, NT, and Zama, Alta.

Commencing July 1, the two-year contract will see GSH fly regular
monitoring flights for Enbridge utilizing two AS350BA intermediate
aircraft based in Fort Simpson and Norman Wells. The contract includes
an option for Enbridge to execute a two-year extension.

"We are extremely happy to have been awarded this contract with Enbridge
and look forward to a long and mutually beneficial relationship," said
Jeff Denomme, President of GSH. "This contract win is a solid
endorsement of our company-wide commitment to safety and customer
service."

Through this contract, GSH will fly line patrols covering the entire
868-km pipeline right-of-way and associated facilities every other week,
as well as providing immediate flights to inspect possible pipeline
irregularities should any be detected by Enbridge.

"We are pleased to be assisting Enbridge, a global leader in the
pipeline industry, with its operations here in the NWT," said Dave
Jennings, President and CEO, Discovery Air Inc. "Enbridge's dedication
to safety is very well aligned with that of Discovery Air and our
subsidiaries, including GSH."

Servicing the contract will also involve two of GSH's Aboriginal
joint-venture partners in the Mackenzie Valley – Dehcho Regional
Helicopters and Sahtu Helicopters.

"The opportunity to work with Enbridge is a clear example of how our
partnership with GSH helps us achieve more than we could on our own,"
said JoAnne Deneron, President of Dehcho Regional Helicopters. "We're
able to realize benefits from a contract like this which extends beyond
the borders of our traditional lands."
