Vernalis welcomes appointment of US co-promotion partner for Frova™

28 March 2002

Vernalis Group plc (LSE: VER) announced today that it welcomes the appointment by Elan Corporation plc (Elan) of UCB Pharma, Inc. (UCB) as Elan's co-promotion partner for FrovaTM in the US.

Robert Mansfield, Chief Executive Officer, commented,We are pleased to see confirmation of UCB as Elan's US co-promotion partner for frovatriptan. UCB will bring an experienced and highly committed sales force targeting primary care physicians (PCPs) and neurologists in the US, which will complement Elan's sales force. We believe that together they will be able to achieve good coverage in the key US market.

Following the appointment of UCB, Vernalis has restructured its loan agreement with Elan. Under the revised commercial terms, Vernalis will no longer have to repay the principle and interest on the loan. Elan will also bring forward a milestone payment due to Vernalis under the licence agreement. In return, Vernalis will receive royalties at a reduced rate on US sales up to a pre-determined level during the launch phase and early years of marketing of Frova. At the end of an initial three-year period, Elan will have an option to extend the reduced royalty period by making an additional lump sum payment to Vernalis. Thereafter, the royalty rate due to Vernalis will revert to the previous levels.

Mr Mansfield added, The new arrangements that we have announced today allow Elan and UCB to maximise their investment of sales and marketing resource during the launch phase of Frova and the early years of sales, whilst providing higher royalties for Vernalis in the later years once the product is established in the market place. We believe this will enable our marketing partners to gain increased market share, which would have a significant long-term benefit for Vernalis. The loan waiver from Elan will also improve our cashflow and financial results for 2002.
