II Assumptions

In arriving at the opinions expressed in clause III below, we have assumed (without verification) cumulatively that:

Bär & Karrer       28 November 2014 3

b) the Documents submitted to us as (hard or electronic) copies are complete and conform to the original document;

c) all signatures and seals on any Document are genuine;

d) where a name is indicated (in print or in handwriting) next to a signature appearing on any Document, the signature has been affixed by the person whose name is indicated, and where no name is indicated (in print or in handwriting) next to a signature appearing on any Document, the relevant Documents have been duly signed by authorized signatories;

e) to the extent any authorizations, approvals, consents, licenses, exemptions or other requirements (collectively the “Authorizations”) had or will have to be obtained outside Switzerland in connection with the issuance of the Allocated Shares, such Authorizations have been obtained or fulfilled or will be obtained or fulfilled in due time, and have remained or will remain in full force and effect at all times through the issuance of the Allocated Shares; and

f) the Board Resolution (i) has been duly resolved in a meeting duly convened and otherwise in the manner set forth therein, and (ii) has not been rescinded or amended and is in full force and effect.

III Opinion

Based upon the foregoing, and subject to the qualifications and reliance limitations set out in clause IV and clause V below, we are of the opinion that under the laws of Switzerland as currently in force and interpreted:

a) the Company is a stock corporation (Aktiengesellschaft) duly organized and validly existing under the laws of Switzerland, with corporate power and authority to conduct its business;

b) The allocation of the Allocated Shares has been duly approved by the board of directors of the Company and each of the Allocated Shares will, upon

(i) issuance of an option over such share in accordance with Swiss law, the Articles, the Plan rules and the Board Resolution;

(ii) exercise of a duly executed exercise notice relating to such option in accordance with Swiss law, the Articles, and the Plan rules; and

(iii) payment of the issuance price (Ausgabebetrag) in respect of such share,

be validly issued, fully paid and non-assessable (i.e. no further contributions in respect thereof will be required to be made to the Company by the holders thereof, by reason only of their being such holders).

c) Insofar as Swiss law is concerned, all regulatory consents, authorizations, approvals and filings required to be obtained or made by the Company for the issuance (Ausgabe) of the Allocated Shares have been obtained or made.

IV Qualifications

The opinions given under clause III above are each subject to the following cumulative qualifications:

a) The opinions expressed herein are strictly limited to matters governed by the laws of Switzerland and thus to opinions on certain Swiss law matters.

b) The newly issued Allocated Shares will have to be registered with the commercial register of the Canton of Zurich, which, however, is not a precondition to their issuance.

c) The opinions expressed herein are based on and subject to the laws of Switzerland as in force and generally interpreted based on available legal sources as of the date of this legal opinion letter, and where this legal opinion letter refers to “Swiss law” or “the laws of Switzerland”, it solely refers to Swiss law as in force and generally interpreted based on available legal sources as of the date of this legal opinion letter. Such laws are subject to change.

d) We have made no investigation of the laws of any other jurisdiction (but the laws of Switzerland) as a basis for this legal opinion letter and do not express or imply any opinion thereon.

e) The opinions expressed herein relate only to legal matters explicitly covered by this legal opinion letter (taking into account cumulatively all assumptions and qualifications) and no opinion is given by implication or otherwise on any other matter.

f) In issuing this legal opinion letter, we based ourselves solely on the Documents and were not instructed to, and did not, make any further independent search or due diligence; we do not opine as to any facts or circumstances occurring or coming to our attention subsequently to the date hereof.

g) The assumptions and qualifications apply to all opinions expressed in this legal opinion letter.

j) As a matter of mandatory Swiss law, shareholders as well as the board of directors of a company are entitled to challenge resolutions adopted by a general shareholders’ meeting believed to violate the law or the company’s articles of association by initiating legal proceedings against such company within two months following such meeting. Therefore, any shareholder or the board of directors of the Company may challenge the resolutions taken by the general shareholders’ meeting of the Company on which the allocation of Allocated Shares by the board of directors and the issuance of the Allocated Shares is based.

k) In this opinion, Swiss legal concepts are expressed in English terms and not in any official Swiss language; these concepts may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions.
