Announcement pursuant to sections 34, 21 para. 2 sentence 1 in conjunction with

section 14 para. 3 sentence 1 no. 2 of the German Securities Acquisition and Takeover

Act (Wertpapiererwerbs- und Übernahmegesetz – WpÜG) regarding the availability of the

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION (IN WHOLE OR IN PART) IN, INTO OR FROM ANY OTHER JURISDICTION WHERE SUCH RELEASE, PUBLICATION OR DISTRIBUTION WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OF SUCH JURISDICTION

On August 15, 2017, Linde Public Limited Company, Guildford, United Kingdom (the “Bidder”), published the offer document (the “Offer Document”) for its voluntary public takeover offer in the form of an exchange offer (the “Exchange Offer”) to the shareholders of Linde Aktiengesellschaft, Munich, Germany (“Linde AG”), regarding the acquisition of all ordinary bearer shares without par value of Linde AG (ISIN DE0006483001 (WKN 648300)) (the “Linde Shares”) for a consideration of 1.540 shares of the Bidder (ISIN IE00BZ12WP82) for each Linde Share. The completion of the Exchange Offer and the agreements which come into existence as a result of accepting the Exchange Offer are subject to certain closing conditions.

The Bidder has lowered the minimum acceptance ratio (within the meaning of Section 12.1.1 of the Offer Document) to 111,382,843 Linde Shares and amended the Exchange Offer accordingly (the “Amendment of the Exchange Offer”). This corresponds to a lowering of the minimum acceptance ratio from 75% to 60% of all Linde Shares entitled to voting rights existing at the time of this publication, excluding, for the avoidance of doubt, any Linde Shares held directly by Linde AG as treasury shares.

Due to the Amendment of the Exchange Offer, the acceptance period of the Exchange Offer is extended by two weeks pursuant to Section 21 para. 5 of the German Securities Acquisition and Takeover Act (Wertpapiererwerbs- und Übernahmegesetz) and in accordance with Rule 14e-1 of the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder. It will expire on November 7, 2017 at 24:00 hours (midnight) (CET).
