                This Amendment No. 3 (this “Amendment”) amends the Schedule 13D filed by Mr. Ernesto Bertarelli and SeroMer Biotech SA (formerly known as “Bertarelli Biotech SA”), a Swiss corporation (société anonyme / Aktiengesellschaft) having its registered office at Chéserex, canton of Vaud, Switzerland, with the Securities and Exchange Commission (“SEC”) on June 27, 2005 (together, with Amendment No. 1 thereto, filed on September 25, 2006, Amendment No. 2 thereto, filed on December 13, 2006, and this Amendment, the “Schedule 13D”), with respect to the Bearer Shares, nominal value CHF 25 per share (the “Bearer Shares”), of Serono S.A., a societe anonyme organized under the laws of Switzerland (the “Company”). Capitalized terms used herein which are not defined herein have the meanings given to them in the Schedule 13D. The purpose of this Amendment is to amend the information contained in Items 4, 5 and 6 of the Schedule 13D.

As a result of the transactions described herein, Mr. Bertarelli no longer beneficially owns more than 5% of the outstanding Bearer Shares and is no longer part of any group with SeroMer Biotech SA. Accordingly, Mr. Bertarelli will no longer file on Schedule 13D with respect to shares of the Company.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended to add to the end thereof the following:

“Pursuant to the SPA, on January 5, 2007, the Offeror acquired all shares of capital stock of SeroMer Biotech SA (thereby acquiring beneficial ownership of the 5,672,772 Bearer Shares held by SeroMer Biotech SA) and the 1,823,740 registered shares of the Company, with a par value of CHF 10, held by the Sellers.

As a result of the transactions pursuant to the SPA, the Sellers ceased to own any shares of capital stock of SeroMer Biotech SA. Also, as a result of the transactions pursuant to the SPA, Mr. Bertarelli no longer beneficially owns more than 5% of the outstanding Bearer Shares and is no longer part of any group with SeroMer Biotech SA. Accordingly, Mr. Bertarelli will no longer file on Schedule 13D with respect to shares of the Company.”

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended as follows:

"(a) Mr. Bertarelli beneficially owns 45,500 Bearer Shares, representing the number of Bearer Shares issuable upon the exercise of options to purchase Bearer Shares held by Mr. Bertarelli that are exercisable within 60 days. The 45,400 Bearer Shares beneficially owned by Mr. Bertarelli represent approximately 0.004% of the outstanding Bearer Shares.

(b) Mr. Bertarelli has the sole power to vote, direct the vote, dispose or to direct the disposition of such Bearer Shares.

The percentage of the Bearer Shares set forth for Mr. Bertarelli in this Item 5 was calculated based upon (i) 10,905,934 Bearer Shares outstanding as of December 14, 2006 and (ii) the number of Bearer Shares issuable upon the exercise of options to purchase Bearer Shares held by Mr. Bertarelli that are exercisable within 60 days. The percentage of the total outstanding votes of the Bearer Shares as a single class set forth in this Item 5 was calculated based on the outstanding Bearer Shares set forth in clause (i) above. Holders of Bearer Shares are entitled to one vote per share on matters submitted generally to the Company's shareholders for their approval.

(c) Mr. Bertarelli has effected the following transactions in the Bearer Shares during the past 60 days:

See Item 4 of this Schedule 13D.

(d) Not applicable.
