Notes to Editors

Background on TSL

Founded in 1995 with headquarters in Aldershot, Hampshire, TSL has used its
proprietary technology to launch successfully two different formulations of the
product and build a development pipeline that addresses the large and fast
growing surgical implant and woundcare markets.  The Company floated in November
2001 and is listed on the Alternative Investment Market.

TSL has a family of products based on the same core technology.  Each product
has been adapted, with unique properties, to make it suitable for use in
different applications.  PelvicolTM/PermacolTM Surgical Implant (SI) is sold
by Bard in the US and Europe for urology and gynaecology applications;
PermacolTM SI (general surgery) is sold for complex hernia repair in the US and
Europe; PermacolTM SI (ENT, plastic and reconstruction) is sold in Europe for
head and neck applications, with an expected US launch in 2003; PermacolTM
Injection (UBA) is an injectable form of PermacolTM used as a urethral bulking
agent to treat female stress incontinence.  Further variations of the sheet and
injectable forms of PermacolTM are being developed for facial augmentation and
reconstruction, and wound therapy applications.

Bard is a trademark of C.R. Bard, Inc. or an affiliate.

Chief Executive's Statement

Review of 2002

The year of 2002, our first full year as an AIM listed company, has been one of
tangible progress for TSL. We have made significant investment in sales and
marketing infrastructure, clinical research and manufacturing capacity as
planned. As a result of this investment, we have increased revenues and margins
in our core surgical implant market, launched our first injectable product and
completed and commissioned our new manufacturing unit in Swillington, Yorkshire.

Strategy & Outlook

Our strategy remains focused on achieving sales growth through the
commercialisation of our core technology by expanding existing product
applications, exploiting new geographical markets and further developing our
product portfolio.  We will continue to invest in highly targeted product
development and clinical programmes with a view to delivering further revenue
growth in 2003 and beyond.

We continue to build the platform to support further significant growth in 2003.
We have sufficient cash resources at December 2002 and remain on course to
achieve profitability and cash generation without the requirement for further
external funding.

Financial Review

The Company increased its product sales by 90% to #3.1m (2001: #1.6m) with
significant growth being achieved both in existing market sectors, principally
urology/gynaecology, and through the development of new applications for
PermacolTM sheet implant in the field of general surgery for hernia repair.  Our
commission-based sales team in the USA was established in June and expanded in
the second half of the year.  The team has made a significant contribution to
revenue growth in the year with sales of #0.4m (2001: nil). A further milestone
was reached with the launch of PermacolTM Injection for the treatment of female
stress incontinence in the last quarter of the year.

Gross margins improved to 48% (2001: 11%) reflecting our move from sub-contract
to in-house manufacturing and the volume and sales mix benefits arising from the
launch of larger sizes of PermacolTM surgical implant.

Research and development expenditure of #1.4m (2001: #1.3m) was incurred in the
year in respect of the clinical trial for PermacolTM Injection UBA and other
product development activities. Administrative expenses increased largely due to
increased investment in marketing of #0.7m (2001: #0.4m), reflecting the
development of our business in the US and as a result of higher insurance
premiums of #0.4m (2001: #0.1m). Net losses were #2.3m (2001: #3.4m including
exceptional expenses of #0.4m).

The second half of 2002 saw a steady weakening of the US dollar, a threat to our
dollar revenue streams. The Board took steps to protect revenues by hedging a
proportion of US dollar currency exposure.

The basic loss per ordinary share of 10.5p compares to a loss per ordinary share
of 25.6p for 2001.

The Company retained a solid cash position as at December 2002 of #5.4m (2001:
#8.7m).

Overall, results were broadly in line with our revised forecasts in terms of
total revenues and significantly better than expected in terms of retained
losses and the Company's cash position.

Operational Review

Sales and Marketing

Revenues for PermacolTM Surgical implant have grown strongly in 2002 and our
strategy is to market this product either directly or through marketing or
distribution partners according to the market and the surgical application being
addressed. The current marketing position for PermacolTM Surgical Implant can be
summarised as follows:

PermacolTM Surgical Implant Marketing 2002/2003:

Application                Market        Regulatory    Route to Market
                                         Status

 *Marketed as 'Pelvicol'

PermacolTM Surgical Implant

-  Urology/Gynaecology - CR Bard Inc
   
CR Bard has worldwide rights to the sheet form of our technology in the field of
urology and gynaecology where it is used for pelvic floor repair and in the
treatment of incontinence. Following the launch in Europe in 2000 and in the US
in 2001, sales of PelvicolTM have grown strongly. In 2002, CR Bard's European
and US operations recorded in-market sales growth of 114% and 100% respectively.
The PelvicolTM brand now represents annual sales for Bard of  $10m (2001:
$5m). In 2002, total revenues to TSL on sales of PelvicolTM increased to #2.3m
(2001: #1.4m). To support further sales growth and market penetration, Bard has
increased both sales force time and marketing spend on PelvicolTM for 2003. As
announced in January, we have signed an agreement with Bard to develop a new
product in this field, for launch in the second half of 2003.

-  General Surgery - Hernia Repair

Our direct sales and marketing team has been selling PermacolTM Surgical Implant
in the UK since 1998 and has enjoyed considerable success in the field of hernia
repair. With this in mind and in the absence of a marketing partner offering us
synergy in general surgery, we launched our commission-only sales team in the US
in June 2002, initially deploying 6 representatives.  This team promotes
PermacolTM for difficult and recurrent hernias where traditional mesh is either
not indicated or has to be removed. The size of this market sector is estimated
at $120m pa. The response from US general surgeons has been very positive and,
as a result, we have built our team up more quickly than originally envisaged to
35 representatives by the end of 2002. From a zero base, we achieved US sales of
$0.6m in 2002, with particular success from larger sizes of PermacolTM in
response to demand from surgeons. We plan further recruitment and we
anticipate continued sales growth in this key target market in 2003.

-  Cranio/Maxillo Facial - Head and Neck

The TSL sales team in the UK has sold PermacolTM into the head and neck field
since 1998 and has demonstrated the benefits of the technology in a range of
surgical procedures. Since being awarded a 510k regulatory approval for the US
market in January 2002, our strategy has been to identify an appropriate
marketing partner for PermacolTM Surgical Implant in this field, worth an
estimated $60m pa.  Discussions with potential partners are ongoing and we
remain confident that the right deal for TSL will be completed in the short to
medium term. Whilst our preference is for a marketing partner to be appointed,
in the event that a distribution deal is not completed in the above time frame,
our strategy, as stated in the interim results, will be to market PermacolTM in
this field directly via our commission-based sales team in the US.

-  Orthopaedic - Rotator Cuff Repair

In November, we announced the award of another 510k approval for PermacolTM
Surgical Implant for the treatment of rotator cuff injuries of the shoulder.
This condition is a common occurrence with age or overuse, and as a result of
sporting injuries.  Severe cases can require surgical intervention and repair.
In the US, there are some 300,000 rotator cuff injuries every year, 15% of which
suffer from post surgical tearing.  We estimate that the immediate target market
in the US for TSL is worth between $45m and $70m per annum. Our sales team in
the UK have been targeting this surgical procedure with success during 2002, and
we are actively seeking a marketing partner to exploit this opportunity in the
US and other key markets.

-  PermacolTM Injection - Urethral Bulking Agent

In August, we announced the limited European launch of our first injectable
product for the treatment of female stress incontinence, an area of significant
unmet medical need.  Marketed directly in the UK by our sales team, our first
sales of this product were made by the year-end. Our strategy is to focus sales
and marketing resource on this area in the coming year and we will rollout the
product into the core European markets as distributors are identified and
signed.

The key market for this product will, however, be the USA with an estimated 7.7m
sufferers of this condition.  Our current clinical activity is expected to
support US regulatory submission in 2003 for product approval anticipated in
2004.

Clinical Programmes

-  PermacolTM Injection (Urethral Bulking Agent)

Patient recruitment for this major clinical trial was completed in June. A
twelve-month period of patient follow-up will result in a submission to the FDA
for a PMA (Pre-Marketing Approval) by the end of 2003 with product approval
anticipated in late 2004.

-  Pilot clinical studies

Utilising our in-house resource, we continue to conduct our own pilot studies
and to work with surgeons in assessing our technology for particular
applications. During 2002, several such studies have been completed and
submitted for publication in peer review journals. This is a highly cost
effective way to generate clinical data and we will continue to invest in this
area in 2003.

Research

Whilst TSL is principally focused on development at this stage in its evolution,
we also have research programmes running in academic institutions, for which we
have secured Government grants. We have a SMART award from the DTI to
investigate the growth of cells in our collagen matrix, and a MedLINK award from
the NHS, in conjunction with Northwick Park Institute for Medical Research,
looking at how such cellular infiltration could be applied to wound care
products. We expect to be in a position to review the technical outcome and
commercial potential of these programmes in late 2003.

Regulatory

During the year, we have been active in making regulatory submissions to gain
access to new markets such as Canada, Australia, and Korea. Once gained, these
approvals will represent a useful extension to the marketing potential of our
products.

Manufacturing

2002 saw a major step forward for TSL with the completion and regulatory
validation of our new production facility at Swillington, Yorkshire.  Building
and fit-out was completed on budget and the operation has been designed to meet
FDA requirements, accepted as being the most rigorous medical device approval
standards. European regulatory validation of the facility was completed in
November when qualification of the production unit to the new ISO 9000 2000
standard was achieved. The first shipment of product from the facility has now
been delivered to customers. This represents a commendable achievement for our
manufacturing, regulatory and quality assurance teams and we thank them for
their considerable endeavours in the year.

Staff

The year saw further investment in the TSL team, particularly in the areas of
marketing, new product development and manufacturing.  We are delighted with the
progress made during the year, which has only been made possible by our ability
to attract and retain high calibre staff. On behalf of the Board, I thank the
entire TSL team for their continuing efforts and look forward to further success
in the coming year.

Current Trading and Outlook

In September we updated the financial markets with our expectations for our
business in 2003, with full year revenue growth in 2003 expected at a comparable
rate to that achieved in 2002.  I am pleased to report that current trading
remains in line with these expectations.
