About TyraTech, Inc. (www.tyratech.com)

TyraTech is pioneering a new class of highly effective, non-toxic, pesticides
and anti-parasitic compounds to address global agriculture, horticulture,
functional foods, healthcare and veterinary markets.  Using a revolutionary
chemoreceptor screening process, TyraTech has identified proprietary blends of
natural oils that stimulate the reactions and biological behaviour of insects
and parasites so that they can be effectively repelled or killed.  TyraTech's
technology avoids both the environmental concerns and human health risks as well
as the development of resistance that are associated with chemical pesticides,
while still providing highly potent efficacy.

TyraTech's products have been validated through strong partnerships with
multinational conglomerates operating within a growing US$23 billion worldwide
market that is being increasingly driven by environmental legislation and
end-user demand.

TyraTech continues to develop new product applications based on safe, natural
ingredients with a broad range of partners around the world.
