Berlin, December 16, 2008 - The Management Board of Jerini AG
(FSE:JI4) has received a formal request, according to section 327a of
the German Stock Corporation (AktG), from Shire Deutschland
Investments GmbH, an indirect subsidiary of Shire plc, (formerly
Shire Limited) with registered offices in Frankfurt am Main, to pass
a resolution at Jerini's General Shareholders' Meeting calling for
the transfer of shares held by Jerini's minority shareholders to
Shire Deutschland Investments GmbH (so-called "Squeeze Out"). As
compensation, minority shareholders will receive payment of adequate
cash compensation from Shire Deutschland Investments GmbH.

Shire Deutschland Investments GmbH intends to offer cash compensation
per share in at least an amount calculated in accordance with the
statutory provisions, the Supreme Court jurisdiction, and the
pertaining rules of the German Institute of Chartered Accountants
(IdW).

Shire Deutschland Investments GmbH has stated that it currently holds
98.32 percent of Jerini's share capital directly, and thus is the
Main Shareholder as defined in section 327a para. 1 sentence 1 AktG.

In addition, the Main Shareholder has also stated that it plans to
propose a resolution at the same General Shareholders' Meeting,
which, if passed, authorizes the Management Board to apply for the
delisting of Jerini AG's shares from the Regulated Market
(Regulierter Markt) of the Frankfurt Stock Exchange (so-called
"Regular Delisting").
