OPINION

QUALIFICATIONS

This opinion is limited to matters of Swiss law as in force on the date hereof and as applied and construed by the courts of Switzerland.

The exercise of voting rights and rights related thereto with respect to any Offered Shares is only permissible after registration in the Company’s share register as a shareholder with voting rights in accordance with the provisions of, and subject to the limitations provided in, the Articles of Association.

We express no opinion as to whether the Registration Statement and the Prospectus are accurate, true, correct, complete or not misleading. In particular, and without limitation to the foregoing, we express no opinion as to whether the Registration Statement and the Prospectus provide sufficient information for investors to reach an informed assessment of the Company and the Offered Shares.

Notwithstanding or irrespective of registration of the capital increase with respect to the Offered Shares with the Commercial Register, the underlying resolutions of the Company’s board of directors or related resolutions of the general meeting may be challenged by a dissenting shareholder of the Company or others in court or otherwise. However, we believe that such challenge of such resolutions after registration of the Offered Shares with the Commercial Register, even if successful, would not in itself void such Offered Shares.

The opinion set forth herein is limited to the matters specifically addressed herein, and no other opinion or opinions are expressed or may be implied or inferred. In particular, we express no opinion as to any commercial, calculating, auditing or other non-legal matters. Further, we express in this opinion no opinion as to tax law.
