QuestAir Technologies and Xebec Adsorption merger to create a North American Leader in renewable natural gas and gas purification

	    <<
	    Complementary transaction offers manufacturing, distribution and
	    technology synergies
	    >>

	    BURNABY, BC, March 17 /CNW/ - QuestAir Technologies Inc. ("QuestAir";
TSX: QAR) is pleased to announce that it has entered into a definitive
agreement with the shareholders of Blainville, Quebec-based Xebec Adsorption
Inc. ("Xebec"), whereby the parties have agreed to combine their businesses to
create a North American leader in the renewable natural gas and gas
purification sectors.
	    Andrew Hall, President and CEO of QuestAir said, "A strategic merger with
Xebec provides a solid platform for the next phase of QuestAir's growth.
Xebec's strength in the natural gas vehicle fuel market perfectly complements
our increased focus and success in renewable natural gas. Together, we will
maximize the potential of QuestAir's advanced adsorption technology by
leveraging Xebec's manufacturing facilities in Quebec and China, and its
global sales and distribution networks."
	    Under the transaction, which requires approval by QuestAir shareholders
and the Toronto Stock Exchange (the "TSX"), QuestAir will issue QuestAir
shares to the shareholders of privately held Xebec. Post transaction, Xebec
shareholders will hold 45% of the merged public company and existing QuestAir
shareholders will hold 55%.
	    Xebec shareholders will be able to earn additional shares to increase
their shareholding to approximately 57% of the merged company. The number of
additional shares earned will be based on the achievement of certain financial
targets in the 2009 and 2010 fiscal years.
	    Both QuestAir and Xebec offer products based on proprietary and
conventional adsorption technology. Xebec is a world leader in natural
gas-drying technology for compressed natural gas ("CNG") fueling stations and
a manufacturer of filtration and dehydration equipment for gases and
compressed air. QuestAir is a developer and supplier of gas purification
systems for the biogas upgrading and industrial hydrogen markets.
	    Xebec is profitable and growing quickly, with top-line growth driven by
increased demand for drying applications for compressed natural gas and
ongoing demand for energy-efficient compressed air dryers. For the fiscal year
ended December 31, 2008, Xebec had revenues of $16.8 million and net income of
$1.2 million (all figures in Canadian dollars).
	    Kurt Sorschak, President of Xebec Adsorption Inc. said, "Xebec has built
a successful and strong business, with loyal customers and a global footprint.
Our merger with QuestAir will help us pursue leadership positions in growing
sectors such as biogas purification, specialized gas filtration, natural gas
dehydration, and hydrogen purification. Currently these segments provide an
addressable market of over $500 million annually and represent a compelling
business opportunity."
	    The merged company will be named "Xebec Adsorption Inc." and Xebec's
current President Kurt Sorschak will be named President and CEO. Andrew Hall,
currently President and CEO of QuestAir, will lead the sales and business
development function. The company will be headquartered in Blainville, Quebec,
a suburb north of Montreal, and will maintain operations in Shanghai,
Singapore, Burnaby and Newcastle (UK).
	    "The transaction announced today will combine two premier clean
technology companies, and create a North American market leader that is a
great deal more than the sum of its parts," said Hall. "We plan to use this
merger to immediately leverage the identified synergies, grow the merged
company quickly and aggressively, and create long-term shareholder value."
	    A merger will enable QuestAir and Xebec to optimize their technologies to
make further inroads in the fast-growing market for CNG as a vehicle fuel,
including renewable CNG produced from biogas. In the United States, natural
gas vehicle fuel consumption has more than tripled in the past decade, from
793 million cubic feet in December 1998 to 2.5 billion cubic feet in December
2008. In addition, adoption of CNG vehicles has been rapid in some developing
countries, and there are now more than seven million natural gas vehicles
worldwide. Compressed natural gas is gaining ground as an affordable,
low-carbon fuel that produces significantly lower levels of greenhouse gases
than oil-based gasoline and diesel.
