The Offer will be launched through the publication of the relevant Offer document subject to the approval of CONSOB. The Offer document will contain the full description of the terms and conditions of the said Offer, including the manner in which it can be accepted.

The Offer is being launched in Italy, since the shares are listed on Mercato Telematico Azionario of the Stock Exchange Market organised and managed by Borsa Italiana S.p.A. and, except as indicated below, is subject to the disclosure and procedural requirements provided by Italian law.

Depending on market conditions, and to the extent permissible under applicable laws and regulations, including Rule 14e-5 under the Exchange Act, and in accordance with applicable Italian practice, the Offeror and/or the Persons Acting in Concert reserve the right to purchase on the market, at any time after the date of this Notice, Issuer's Shares outside the Offer, for the purpose of further increasing such persons' shareholding in the Issuer's share capital. To the extent information relating to such purchases it is made public in Italy, such information will be disclosed by means of a press release or other means of communication of equivalent scope in order to inform the Issuer's U.S. shareholders. No purchases will be made outside of the Offer in the United States of America by or on behalf of the Offeror and/or Persons Acting in Concert.

An Offer Document translated into English will be made available to the holders of the Shares resident in the United States of America. The English version of the Offer Document will be merely a courtesy translation and the Italian version of the Offer Document will be the only document submitted to CONSOB for its approval.
