BOARD OF DIRECTORS' MEETING AND RESOLUTIONS ON CORPORATE GOVERNANCE

At the end of the Shareholders' Meeting, the new Board of Directors met and appointed Michele

Denegri as Chairman, Giancarlo Boschetti as Deputy Chairman and confirmed Carlo Rosa (General

Manager of DiaSorin) as the Company's Chief Executive Officer, conferring the respective mandates and powers.

Having noted the declarations of the Directors who declared they meet the independence requirements and taking into account the information available to it, the Board of Directors was satisfied, with the favorable opinion of the Board of Statutory Auditors, that the Directors André Michel Ballester, Roberta Somati, Francesca Pasinelli, Fiorella Altruda, Monica Tardivo, Tullia Todros and Giovanna Pacchiana Parravicini meet the independence requirements of current legislation. Regarding this matter, please note that the Board of Directors considered it appropriate not to apply Recommendation no. 7, letter e) of the Corporate Governance Code to Director Somati.

In the Company's interest, the Board deemed it appropriate to continue to avail itself of the high level of professionalism and experience of this Director and therefore preferred a figure of substance in its evaluation of the composition of the administrative body and its Committees.

On the other hand, the Directors Carlo Rosa and (by virtue of the management positions held at DiaSorin) Chen Menachem Even qualify as Executive Directors.

During the Board of Directors' meeting, the Board of Statutory Auditors, pursuant to the requirements of Recommendation no. 9 of the Corporate Governance Code, confirmed the fulfilment of the independence requirement for the Standing Auditors, as the Board verified on today's date. The

Board of Statutory Auditors informed that it considered it appropriate to disregard Recommendation no. 7, letter e) of the Corporate Governance Code, regarding Standing Auditor Ottavia Alfano, as she is highly professional. There are no relationships that could or appear to be such as to compromise her independence of judgement and unbiased appreciation of the work of management, thus favoring a figure of substance when assessing the Board of Statutory Auditors.

The Board also confirmed the creation of the following committees:

Roberta Somati, Chairman (non-executive and independent director) Giancarlo Boschetti (non-executive director)

Giovanna Pacchiana Parravicini (non-executive and independent director)
