QuestAir Announces Employee Share Purchase Plan

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Feb. 28, 2007) - QuestAir Technologies Inc.
(TSX:QAR)(AIM:QAR) announced today that the Board of Directors have approved the introduction of
an Employee Share Purchase Plan ("Plan") in order to encourage employees to invest in the common
shares of the company.

Effective immediately, eligible employees can elect to invest up to 5% of their salary into
QuestAir common shares, which will be purchased on the Toronto Stock Exchange at regular quarterly
intervals through a third party Plan administrator. The first share purchase under the Plan is
expected to occur on or about June 1, 2007. Participating employees are eligible to receive
matching contributions from the Company on the first anniversary of each purchase at a rate of
fifty percent (50%) of their net cash contribution.

The company announced that two executive Directors have elected to participate at the maximum
contribution level allowed under the Plan. Jonathan Wilkinson, President, Chief Executive Officer
and Director, and Sherry Tryssenaar, Chief Financial Officer and Director, have each enrolled in
the Plan and elected to direct 5% of their respective salaries to the purchase of common shares
under the Plan starting March 1, 2007. In addition, key members of the management team have also
elected to participate in the Plan. Non-executive Directors are not eligible to participate in the
Plan.

The Plan was approved by the Board of Directors in order to more closely align the goals of
QuestAir's management and employees with the interests of shareholders.

"The Board of Directors of QuestAir supports measures to increase the share ownership position of
all employees including the executive team," said Jonathan Wilkinson. "At the same time, the Board
recognizes the need to limit the level of dilution under compensation arrangements. Accordingly,
this Plan has been established as an open market purchase plan, such that shares are purchased in
the market at current market prices rather than purchased at a discount from treasury."

Disclosure of the Directors enrolment in this Plan is made pursuant to the rules governing the
operation of AIM as established by the London Stock Exchange Plc.
