2. This is MEDIVIR OUR research is based on the know how of proteases and polymerases. The aim is to have a steady flow of CDs into clinical development. WE focus on mainly two therapeutic areas; infectious and immunological diseases. OUR pipeline is balancing commercial opportunities and development risks. WE are one of the largest biotech companies in Europe in terms of pipeline and employees, located in Cambridge (UK) and Huddinge (SE). WE own CCS, a specialty pharma company. Most likely to have one product to launch in 2005.

3. Medivir has a broad know how in these enzymes, enabling a variety of research options and still be focused. Proteases and polymerases represent major pharmaceutical opportunities

6. Status October 2002 Partnership and deal values Partnership and deal values Deal values for existing partnerships amounts to SEK 700 million (refers to 3 deals) of which SEK 100 million is down payments to be accounted as revenues during 2002. Cash wise, Medivir has received SEK 80 million of these during H1 2002. Medivir has retained the Nordic marketing rights for RP-606 and MV026048. Corporate Peptimmune 50/50 ”joint venture” for Cathepsin S in late pre-clinical research. Chiron for Hepatitis C in pre-clinical discovery. Roche for HIV-NNRTI in late pre-clinical development. Reliant in RP-606 (Shingles) on its way to phase III. University University of Dundee – AEP, autoimmune disorders, in early pre-clinical discovery. St:George (London, UK) – Cathepsin K, osteoporosis, in pre-clinical lead identification phase. MRC (London, UK) – broad anti-bacterial program, in early pre-clinical discovery. Karolinska Institute – Alzheimer disease, in pre-clinical discovery. Agrivir – Joint venture med BioAgri. And several other universities in Sweden, US and UK.

7. Status October 2002 Financial The group, period ending 30 June Profit after financial items amounted to SEK 4,3 (-68,0) million. Cash SEK 195 million. Going forward, the R&D expenditure will be in the range of 150- 160 MSEK on a rolling 12 month average. CCS, a strategic and financial asset to Medivir Net sales SEK 76,7 (63,8) million during H1 (2002); SEK 9,7 (9,7) million profit. Cash positive operations. CCS had extraordinary costs amounting to MSEK 4,5 during H1 (2002) for investments for the coming AstraZeneca production. Significant increase in sales, profit and “market cap” predicted over next years from both internal activities and by aggressive acquisition strategy.

8. Status October 2002 Pipeline Varity of projects focusing on; HIV, Hepatitis, Cold sores, Shingles, MS, RA and Osteoporosis of which; »4 projects in clinical development »4 late stage pre-clinical projects »More than 10 discovery activities

9. Status clinical projects RP-606 - Shingles: Licensed to reliant in February. Transfer of project completed in May. Planning and development work ongoing towards phase III studies. Waiting for the end of phase II meeting with FDA. ME-609 - Cold sores: Seeking partnership in order to conduct phase III studies. MIV-310 - HIV: Phase IIa results reported during summer. Planning for phase IIb studies and seeking partnership in parallel. MIV-210 – Hepatitis B and HIV: Results from pre-clinical studies reported at ICAAC in September. Ongoing phase I trails and planning for phase IIa studies, both for Hepatitis B and HIV. (MV026048 – Licensed to Roche in April. Transfer of project completed in June. Now in late pre-clinical development towards clinical trails during 2003.)

11. Medivir’s strategy going forward

12. Strategy going forward 2003 Mainly two internal clinical programs ongoing, MIV-310 and MIV-210. The aim is to find partners for all clinical projects. The aim is to balance risk/benefit in an optimal way. Secure the Nordic rights in future partnerships. Use CCS as a financial asset and develop it accordingly. Continue aggressive “Key Account Management”. Continue the focusing process in order to increase research capacity to speed up several promising pre-clinical activities and projects. Add pre-clinical collaborations and partners. Add new targets. Expand size and coverage of protease and polymerase inhibitor libraries by building up of matrix metallo & serine protease inhibitor library. Position Medivir as the preferred partner in protease and polymerase research.

13. Medivir as an investment ”Well positioned for success and value creation” Medivir is one of the largest biotech companies in Europe in terms of pipeline and personnel. Is establishing itself as the research driven small pharmaceutical company. CCS is a strategic asset in this process. Large scientific and commercial opportunities in pipeline. Solid financial position including opportunities in late stage clinical projects. Existing and future partnerships will secure speed of development adding value to the shareholders. Most likely to have one product to launch in 2005.
