Ger van Jeveren, CEO of Arseus: ‘Arseus had a good start of 2011 with turnover growth of 15.0% and organic growth of 3.2%. All divisions of Arseus laid a solid foundation for growth by continuous investments in innovation and product development. This press release explains a number of these innovations.
In the first quarter, the integration of the Brazilian DEG and the Belgian Devroe, both acquired in December, was successfully completed. I am enthusiastic about the many benefits and possibilities that these acquisitions offer for our clients and our employees.
In 2011 Fagron wants to further strengthen its worldwide market leadership in the rapidly growing market for pharmaceutical compounding. Add-on acquisitions in existing markets are being considered for Arseus Dental, Arseus Medical and Corilus as suitable opportunities arise.
We look to the future with confidence and consequently confirm the expectations for 2011 that we announced earlier.’

2 Unaudited management figures.

Fagron
Fagron’s turnover increased 32.8% in the first quarter. Organic growth was 8.2%. Fagron’s persistently strong turnover growth is due to the successful revitalisation of pharmaceutical compounding to fulfil the growing worldwide need for tailor-made medication.
Fagron continuously invests in innovation and the development of new concepts and products for pharmaceutical compounding. The first quarter of 2011 proved that the combined product range created by the successful integration of the American Gallipot and the Brazilian DEG had already resulted in great advantages.
In 2011 Fagron wants to further strengthen its market leadership in the rapidly growing market for pharmaceutical compounding through robust organic growth and a focused buy-and-build strategy. The emphasis in Europe is on acquisitions in the existing markets, and in Scandinavia
and Central and Eastern Europe. Fagron is also looking for acquisition possibilities in North America and Latin America in order to further strengthen Fagron’s market positions in these regions.

Arseus Dental
Arseus Dental’s turnover increased 2.3% in the first quarter of 2011. Organic growth was 0.1%.
The activities focused on dental practices were further integrated in the first quarter. The emphasis here was on the strategic structuring of product portfolios and the introduction of total solutions that increase efficiency. Arseus Dental’s concepts for structuring dental practices that
have been successful in the Netherlands and Belgium will soon be introduced in Germany and France. With strong A brands in combination with 3D imaging equipment, intra-oral sensors from OwandyTM and practice management software from JulieTM and BaltesTM, all developed inhouse, Arseus is excellently positioned to profit from the increasing digitalisation in the dental
world.
In Arseus Dental’s technological activities, the emphasis was on the introduction of innovative technology that improves the quality, efficiency and effectiveness of both dental laboratories and dentists. In the first quarter, the Ceka-Preciline attachments product range was further expanded
and the private quality brand Selexion was introduced to the international dental market during the IDS dental trade fair in Cologne. Selexion includes a wide range of products that are used daily by dental laboratories.

Arseus Medical
In the first quarter of 2011, the focus at Arseus Medical was on simplifying its market approach
and expanding its range of high value-added solutions. Arseus Medical saw growth of -1.0% in the
first quarter. Organic growth was -6.5%. Despite the negative organic growth, Arseus Medical has
a solid pipeline of innovative products and solutions with substantial added-value that constitute
the basis for future growth.
The ‘Surgery to Sterilization’ concept (‘S2S’) offers total solutions for surgery and sterilisation
departments in hospitals and concentrates on improving the efficiency, traceability and quality in
instrument and implant management. The activities of Devroe Instruments, acquired at the end
of 2010, and the surgery and sterilisation activities of Arseus Medical have been brought together
and integrated under the name Arseus Devroe. Arseus Medical also strengthened its position in endoscopic surgery with the introduction of tailor-made packages of surgical instruments at Duo- Med.

Corilus
Corilus managed to continue its strong organic growth from 2010 into the first quarter of 2011.
Turnover increased by 15.5%. Organic growth was 4.6%. This growth was realised by further strengthening its market leadership in Belgium and the successful international roll-out of medical software.
Corilus started the sale of high qualitative measuring equipment from Nidek in cooperation with Arseus Medical. This enables it to offer total solutions to opticians. Corilus entered into a partnership with Vitalsys for telemonitoring. VitalCare is a web-based application that allows
doctors to monitor patients’ vital parameters remotely using software for general practitioners from Corilus.
In the first quarter of 2011, Corilus strengthened its position on the Belgian market for software
for Residential Care Centres with the acquisition of the Belgian company CMS. As a result of this
acquisition, Corilus can quickly respond to and profit from the consolidation trend among
Residential Care Centres. An additional advantage is that Corilus can directly integrate its Infiplus
software for home care nurses with CMS’s GERACC software for Residential Care Centres. This
enables it to respond to the important development that Residential Care Centres are increasingly
cooperating with home care.
Exercise of warrants / Development in treasury shares
On 18 February 2011, Arseus issued 1,018 new shares as a result of the exercise of warrants under
the Warrant plan of the Offer. These newly issued shares are entitled to dividend as of the 2011

shares will be listed on a separate line at NYSE Euronext (ISIN code BE0380320805). The
number of Arseus shares with voting rights is 31,196,139. The total number of voting rights
(denominator) is 31,196,139. The authorised capital is € 319,820,911.43.
As of 31 December 2010, Arseus owned 1,300,585 treasury shares. The acquisition of the Belgian
CMS was partially financed with treasury shares. As a result, the number of treasury shares
decreased. At 31 March 2011, the number of treasury shares totalled 1,105,585.

Outlook3
Based on the current view and the existing Arseus portfolio, Arseus’ management is expecting turnover growth of between 8% and 12% in 2011, organic growth in turnover of between 3% and 6% and a recurring EBITDA that is expected to grow faster than turnover.
