            TyraTech receives Arysta LifeScience milestone payments



XL TechGroup (AIM: XLT), the creator of companies that solve identified, global
unmet market needs, is pleased to advise that its portfolio company, TyraTech
Inc. (AIM: TYR) ("TyraTech"), the pioneer of safer, effective and natural
pesticide products, has achieved development and financial milestones with
Arysta LifeScience Corporation ("Arysta"), as part of its 2006 exclusive global
licensing and co-development agreement to manufacture and market a number of
insecticide products for certain horticultural markets.



The milestone payments relate to achieving specific insecticide efficacy and
cost targets for TyraTech Natural products in two of the licensed applications.
Field testing for the lead product prototypes has been underway since late 2006,
when an exclusivity payment was received.



Dr John Scott, CEO of XL TechGroup, said: "Many horticultural pests have
developed resistance to traditional insecticides.  As a result, the growing
worldwide insecticide market is looking for safe, natural solutions that work,
and TyraTech is perfectly positioned to bring its unique technology and
experience to bear.  The Arysta partnership represents just one element of the
broad range of applications and markets for TyraTech's technologies.  We are
pleased with TyraTech's continuing progress in implementing its business
strategy to plan, and we look forward to further positive developments over the
coming months."

NOTES TO EDITORS



About XL TechGroup

XL TechGroup is in the business of significant value creation.  Working with
major international corporate and technology partners such as AES, Procter &
Gamble and leading universities, XL TechGroup first identifies global unmet
market needs and then targets and exploits these by the systematic creation of
successful, disruptive technology businesses.  These new companies are built
from scratch, and are then managed, developed and funded by XL TechGroup through
to the point of a trade sale or a stock market listing.



XL TechGroup's unique and proven methodology selects the best opportunities in
order to create one-to-two new companies annually, where each company is
expected to achieve a realisable valuation of at least US$400 million within
four years from its creation.  It is XL TechGroup's aim to deliver significant
shareholder distributions at the final exit from each company.



XL TechGroup's companies to date are:

*  PetroAlgae LLC (www.petroalgae.com)

*  TyraTech Inc. (AIM: TYR, www.tyratech.com)

*  DxTech LLC (www.dxtech.com)

*  QuoNova LLC (www.quonova.com)

*  AgCert International plc (LSE: AGC, www.agcert.com)



XL TechGroup has also established GenXL LLC as a joint venture to capture the
value of those prospects that do not fully meet XL TechGroup's US$400 million,
four year criteria but still demonstrate considerable potential worth.  Over and
above XL TechGroup's core business model, GenXL has announced its first
investments and is reviewing a flow of opportunities from both XL TechGroup and
GEN3 in order to generate new companies, standalone product lines and technology
licensing opportunities or an appropriate mix of these.

About TyraTech, Inc.

TyraTech is pioneering a new class of highly effective, 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
prevents the development of resistance and avoids the environmental concerns and
human health risks of chemical solutions whilst still being at least, if not
more, effective.



The Company'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.  www.tyratech.com.
