BASF Extends $37 Cash Tender Offer to April 28, 2006

Ludwigshafen, Germany, April 17, 2006 – BASF Aktiengesellschaft (Frankfurt: BAS, NYSE: BF [ADR], LSE: BFA, SWX: AN) today announced that, through its wholly owned subsidiary, Iron Acquisition Corporation, it has extended the expiration date of its $37 cash tender offer for all of the issued and outstanding shares of common stock of Engelhard Corporation (NYSE: EC) to 5:00 p.m., New York City time, on Friday, April 28, 2006. The tender offer had previously been scheduled to expire at 5:00 p.m., New York City time, on Friday, April 14, 2006.

On April 11, 2006, BASF received a letter from Engelhard’s financial advisor in which Engelhard requested a firm offer no later than April 19, 2006. BASF continues its review of non-public information provided by Engelhard and has not decided whether to submit a revised offer to Engelhard’s management and, if it does, at what price.

BASF has been informed by The Bank of New York, the Depositary for the offer, that, as of 5:00 p.m., New York City time, on April 14, 2006, a total of 654,180 shares of Engelhard common stock had been tendered into the offer and not withdrawn. As a consequence of the extension of the expiration date, holders of Engelhard common stock may tender their shares until 5:00 p.m., New York City time, on Friday, April 28, 2006, unless the offer is further extended.



BASF currently intends to solicit proxies for use at Engelhard’s 2006 annual meeting of stockholders, or at any adjournment or postponement thereof, to vote in favor of BASF’s nominees identified in the revised preliminary proxy statement on Schedule 14A filed with the U.S. Securities and Exchange Commission (the “SEC”), and to vote on any other matters that shall be voted upon at Engelhard’s 2006 annual meeting of stockholders. On February 27, 2006, BASF filed a revised preliminary proxy statement on Schedule 14A with the SEC in connection with this solicitation of proxies. All Engelhard stockholders are strongly encouraged to read the revised preliminary proxy statement and the definitive proxy statement when it is available, because they contain important information. Engelhard stockholders may obtain copies of the revised preliminary proxy statement and related materials for free at the SEC’s website at www.sec.gov.

The identity of people who, under SEC rules, may be considered “participants in a solicitation” of proxies from Engelhard stockholders for use at Engelhard’s 2006 annual meeting of stockholders and a description of their direct and indirect interests in the solicitation, by security holdings or otherwise, are contained in the revised preliminary proxy statement on Schedule 14A that BASF filed with the SEC on February 27, 2006.
