"The current share price represents an excellent opportunity for us to initiate a new share buy-back program," said Ernesto Bertarelli, Chief Executive Officer of Serono. "This initiative reflects our commitment to promote long-term shareholder value." The authorization applies only to the bearer shares traded on virt-x, and excludes the American Depositary Shares traded on the New York Stock Exchange. It is subject to the approval of the Swiss Takeover Board and the Swiss Stock Exchange. The share buy-back program is expected to start in June 2004 and will last for a maximum period of five years. The shares will be purchased on the open market via a second trading line, and subsequently cancelled. This will result in a reduction of the number of shares outstanding and thus increase earnings per share. Serono's first share buy-back program has fully utilized the CHF 500 million allocated and a total of 647,853 shares have been bought back as treasury stock for general corporate purposes. 1/2 ### Some of the statements in this press release are forward looking.
