Galapagos and ProStrakan receive additional milestone payment in antibody collaboration

MECHELEN, BELGIUM and GALASHIELS, SCOTLAND--(Marketwire - September 27, 2007) -



Mechelen, Belgium and Galashiels, Scotland; 27 September 2007 - Galapagos NV (Euronext & LSE: GLPG) and ProStrakan Group plc (LSE: PSK) announced today the achievement of the third milestone under Galapagos' collaboration with Novartis in antibodies for bone-related diseases. Today's milestone triggers a payment of $1.5 million to Galapagos. Galapagos will pay $1,125,000 of this amount to ProStrakan as part of their December 2006 agreement.

The collaboration was initially formed between Novartis and ProSkelia SASU (formerly a subsidiary of ProStrakan) in September 2006. Under the terms of the original agreement with Novartis, total milestones could eventually exceed $100 million, with undisclosed royalties payable on commercialization. The first milestone payment, which was related to intellectual property, was announced on 6 December 2006. The collaboration was then transferred to Galapagos as part of its acquisition of ProSkelia from ProStrakan on 22 December 2006. Under the terms of Galapagos' acquisition of ProSkelia, Galapagos and ProStrakan split milestone and royalty income from agreements existing at the time of the acquisition 25% for Galapagos and 75% for ProStrakan, while Galapagos retains all R&D fees.

"We are pleased to announce another milestone achievement in this collaboration with Novartis," said Onno van Stolpe, CEO of Galapagos. "This milestone further testifies to the strong performance of the research teams."

Dr Wilson Totten, Chief Executive of ProStrakan added, "In addition to the commercialisation of existing products we continue to benefit from ongoing milestone payments associated with our ongoing arrangement with Novartis and Galapagos. I look forward to further revenues in due course as a result of this collaboration."
