Leiden, The Netherlands, May 28, 2010. Biotech company Pharming Group NV ("Pharming" or "the Company") (NYSE Euronext: PHARM) announces that it has successfully completed an equity fundraising of €12.0 million through a private placement of ordinary shares with new and existing investors (the "Offering"). The Company deems the net proceeds of the Offering sufficient to finalize the regulatory approval process and start of commercialization of Rhucin for the treatment of Hereditary Angioedema, if the marketing authorisation by the European Union is granted.

In the context of the Offering, a total of 100,000,000 million new shares (the "Offer Shares") have been offered for an issue price of €0.12 per Offer Share. The Offering was launched this morning and the order book for the Offering was closed today . Payment for and delivery of the Offer Shares is expected to take place 3 business days after today, at which date the Offer Shares are expected to be admitted to trading and listing of Euronext Amsterdam by NYSE Euronext. As a result of the Offering and a number of anti-dilution events triggered by the Offering, Pharming's total number of outstanding ordinary shares will increase to 272,447,697.

"We are very pleased with the successful completion of this financing round. The progress of the review of the European Marketing Authorization of Rhucin, the now anticipated favorable opinion already in June 2010, the recently announced commercialization agreement for Rhucin with Swedish Orphan Biovitrum and the recently announced initiation of the spin-off of DNage have provided the basis needed to raise new funds in this very challenging market environment," said Sijmen de Vries, MD, MBA, Chief Executive Officer.

Pharming was advised in this Offering by Loyens & Loeff NV, Kempen & Co and Petercam Bank NV.
