3. SAINT-GOBAIN’S HOSTILE TAKEOVER ATTEMPT

FUNDAMENTAL REASONS TO OPPOSE HOSTILE TAKEOVER ATTEMPT BY SAINT-GOBAIN

32

1. Lack of industrial logic

2. Saint-Gobain will execute control with only 16% of the capital

3. No adequate representation of public shareholders on the Board

4. Saint-Gobain is a direct competitor of Sika

5. Sika loses A- credit rating

6. Sika’s Growth Model at risk

“The Board of Directors reserves the right to refuse an acquirer of registered shares as shareholder, if the number of registered shares held by him exceeds 5% of the total number of registered shares entered in the commercial register.

[…¨]natural persons or legal entities or, which act in concert in view of a circumvention of registration limitations, are regarded under these provisions as a single buyer.”

Many other Swiss companies have a similar restriction of transferability with a threshold (Vinkulierung) such as: Nestlé, Novartis, Swatch, Swisscom, Guivaudan, Sonova, Schindler, Lindt & Sprüngli.

33

SIKA ARTICLES OF ASSOCIATION ARTICLE 4 RESTRICTION OF TRANSFERABILITY, THE 5% THRESHOLD

4. OUTLOOK

2015 Sales growth expectations of 5% at constant exchange rates

Continued build-up of growth markets with investments in new factories and the establishment of new national subsidiaries

Double-digit sales growth expected in the Mexico, Africa, the Middle East, Eastern Europe, Southeast Asia and the Pacific

Negative market development expected in China, Brazil, Russia and France

The appreciation of CHF remains a challenge

Above-average rise in margins expected thanks to continued volume growth, efficiency improvements and lower commodity prices
