Provided that the Extraordinary General Meeting of Diamyd Medical AB (STO:DIAM-B)(Pink Sheets:DMYDY) to be held on April 22 resolves in favor of the proposed restructuring of the Diamyd Group, after which Diamyd Medical AB will be renamed Mertiva AB, the incoming Board of Directors in the future Mertiva AB plans to appoint Andreas Bergsten as the President at a statutory meeting following the General Meeting.

Background to the restructuring

As previously announced in press releases issued on February 18 and March 21, 2013, the summons to an Extraordinary General Meeting was brought about due to an agreement reached by a group of shareholders in Diamyd Medical AB who together represent a majority of the votes and share capital in the company. The agreement entails, among other factors, that the shares in the subsidiary Diamyd Therapeutics AB, which will be capitalized at approximately SEK 50 million and own the existing diabetes operations and the holding in Periphagen, Inc., will be distributed to shareholders. The company will be renamed Diamyd Medical AB. At the same time, the Parent Company will be renamed Mertiva AB. Liquid assets of more than SEK 300 million and the holdings in Protein Sciences Corporation and Mercodia AB will remain in Mertiva AB. The greater part of the liquid assets in Mertiva AB is proposed to be distributed to the shareholders as soon as possible.

Change of President in Diamyd Medical (future Mertiva)

The incoming Board of Directors of the future Mertiva AB plans to appoint Andreas Bergsten as President in a statutory Board meeting following the Extraordinary General Meeting to be held on April 22.

Andreas Bergsten, born in 1967, is currently working as a consultant in the fields of finance and company management and, in his capacity as a consultant, has worked primarily for venture capital firms. In the past, Andreas has served as CFO of four different companies and, prior to this, he was employed at Citigroup, initially as a financial analyst and subsequently as a key account manager. Andreas holds a Master of Science in Business and Economics from the Stockholm School of Economics and the McGill University MBA Program.

The incoming Board of Directors of the future Mertiva AB intends to bring up the issue of moving the company’s listing from NASDAQ OMX Nordic Stockholm to another, unregulated marketplace.

Redemption procedure in Diamyd Medical (future Mertiva) and distribution in kind of Diamyd Therapeutics
