4SC and XL TechGroup found new company for the development of biofilm
inhibitory substances

Planegg-Martinsried, Germany, 28 December 2006 - The drug discovery and
development company 4SC AG (Frankfurt, Prime Standard: VSC), based in
Martinsried, Germany and Florida US based XL TechGroup, Inc. (AIM: XLT)
announced today the formation of a new company for the development and
marketing of substances which influence bacterial biofilm formation. The
company, with the name QuoNova, is registered in the US and has obtained
4SC AG’s exclusive global rights to the substances and related know how.

In return 4SC AG will receive payments totalling US$2 million together with
research funding, staged over several years, as well as a 10 per cent
equity interest in QuoNova.

Information and Explaination of the Issuer to this News:

The business model of Florida-based XL TechGroup, which is listed on the
AIM, consists of first identifying global unmet market needs and then
targeting and exploiting these by the systematic creation of successful,
disruptive technology businesses. These are built from scratch, and are
then funded and developed by XL TechGroup through to the point of a trade
sale or a stock market listing. The first company created under the XL
TechGroup banner in 2002, AgCert International, was listed on the London
Stock Exchange in June 2005.

In 4SC AG's QSB substances (QSB stands for 'Quorum Sensing Blocker'), the
XL TechGroup sees great potential for marketing in the most diverse areas.
These substances prevent the colonisation of surfaces by bacteria (known as
'biofilms') by blocking their intercellular communication systems. In
contrast to conventional forms of antibiotic treatment, they have no toxic
effects and involve only a minimal risk of building up resistance. QSBs are
therefore suitable for a wide range of applications, for example as
therapeutics or consumer health care products, as well as for industrial
and environmental health applications. 4SC AG identified the QSB substances
prior to a strategic decision which necessitated focussing their pipeline
projects on inflammatory diseases and cancer.

'The possible applications of these biofilm blockers are almost unlimited,'
says John S. Scott, CEO of XL TechGroup. 'We will be evaluating all the
development options for this project in the coming months, and then
establishing the future timetable.'

About 4SC
4SC AG (ISIN DE0005753818) has been listed in the Prime Standard of
Frankfurt Stock Exchange since 15 December 2005. Founded in 1997 and now
with a staff of 59, the company develops novel drug candidates for
inflammatory diseases and cancer using a cheminformatics based technology
platform. Traditional high throughput screening of therapeutic agents has
been transferred from the lab to the computer. Thus, the company offers
substantial cost and time advantages as well as increased success rates in
drug development. 4SC AG uses its patented technology platform to create a
sustainable product pipeline for active agents that are developed in early
clinical phases ('proof of concept') and subsequently result in upfront and
milestone payments as well as participation in sales generated by
out-licensed products to the pharmaceutical industry. There are currently
five projects in the pipeline. The first project on the treatment of
rheumatoid arthritis is currently undergoing clinical phase IIa. Three
other product candidates are in pre-clinical development and another
project is in the research stage. Furthermore, the company has its
technology platform in co-operation projects with biotech and pharma
companies and is already generating initial revenues.
