     relationship with TyraTech

•    development of a new product area - 'Natures Natural', a fully sustainable 
     horticultural and garden product that is intended to replace peat in growth 
     or potting soil mixtures, which could generate revenue in the next few months

Dr John Scott, CEO of XL TechGroup, commented on TyraTech's Interim Results:
'Since coming to AIM earlier this year, I am pleased to report that TyraTech has
continued to make strong progress.  The Syngenta milestone payment is just the

coming months, while TyraTech's technology platform has the ability to produce a

confident that TyraTech will become an increasingly valuable asset in the XL
TechGroup portfolio.'

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.  While an XL TechGroup company might perform a
stock market listing at an earlier point in this four year timeframe, XL
TechGroup would retain a controlling interest and would continue to assist with
the company's development.  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:

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

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

•         DxTech LLC (www.dxtech.com)

•         PetroAlgae LLC (www.petroalgae.com)

•         QuoNova LLC (www.quonova.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 is reviewing a significant 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, 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 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.
