In order to minimize the risks entailed by the ongoing Covid-19 medical crisis, and in compliance with Article 106 of Italian Decree Law 18/20 converted into Law by Art. 1 of Law 24 April 2020 No. 27 and subsequent amendments and additions, shareholders shall attend the General Meeting exclusively via the appointed representative pursuant to article 135-undecies of Legislative Decree 58 of 24 February 1998 (the "CFA") - i.e. Computershare S.p.A (hereinafter the "Appointed Representative") - according to the procedure described herein.

In compliance with art. 106, paragraph 2 of the Decree Law 18/20, unless otherwise stated above, attendance at the General Meeting by corporate offi cers, the Company Secretary and/or the Notary and the Appointed Representative, in addition to any other persons so authorised by the Chairman of the Board of Directors, may take place via video or telephone conferencing, in accordance with the legislation introduced to face up to the COVID-19 epidemic. This must be done in such a way as to guarantee the identifi cation of attendees in accordance with the procedures to be defi ned by the Chairman and notifi ed to each of the above persons, in compliance with the legislation applicable to such cases, without in any event being necessary for the Chairman, the Secretary or the Notary to be present at the same location.
