Board Changes

Aortech International PLC 13 May 2005 For Immediate Release 13 May 2005 AorTech International plc ('AorTech' or the 'Company') Board Changes AorTech International plc (AIM:AOR), the biomaterials Intellectual Property and Material Manufacturing Company today announces changes to its Board as a consequence of restructuring of the business. Laurie Rostron, Chairman, and Peter Gibson, Non-Executive Director of the Company have stepped down and Jon Pither has assumed the role of Chairman. The Board also announces the appointment of Dr Stuart Rollason as a Non-Executive Director. The Board is of the view that the family of Elast-Eon(TM) polymer biomaterials is being successfully developed to the point where its potential is increasingly being recognised as the material of choice for an array of long-term, high fatigue, blood contacting medical device applications. Good progress has also been made with the internal development of high value-added platforms for Elast-Eon(TM), particularly with next generation breast implant and heart valve products. It is anticipated that opportunities for these markets will be exploited through licensing opportunities with its partners, or alternative means of investment. Jon Pither, who has considerable experience of managing such opportunities, has been appointed to oversee the development of these initiatives, for the full exploitation of these technology assets. It is intended that Union Investment Management Ltd (which has a relationship with one of the Company's shareholders) will also be engaged to assist the Board with this project. Commenting on the restructuring, Jon Pither, Chairman said: 'Elast-Eon(TM) has reached a stage where large established companies in the biomaterials market should find it attractive to commercialise the successful development advances that have been achieved.'
