Ludwigshafen, Germany, May 1, 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 tender offer with the Securities and Exchange Commission (SEC) to 5:00 p.m., New York City time, on June 5, 2006.  BASF has also increased the cash price being offered to shareholders in BASF’s tender offer for 100 percent of Engelhard’s outstanding shares to $38 per share. The tender offer had previously been scheduled to expire at 5:00 p.m., New York City time, on Friday, April 28, 2006.

“BASF believes that its offer for all of Engelhard’s shares provides greater value and more certainty to Engelhard’s shareholders than what may be achievable through the Engelhard leveraged recapitalization and 20 percent share buyback,” said Dr. Jürgen Hambrecht, Chairman of the Board of Executive Directors of BASF Aktiengesellschaft. “Our offer allows Engelhard’s shareholders to maximize value today and without risk, instead of waiting and hoping for a highly leveraged Engelhard to deliver on its promises.”

“Merging Engelhard’s business with BASF will create a leading global player in the catalyst and pigments business. Building on the expertise of Engelhard’s employees, we will be able to offer new and superior solutions to our customers and develop new markets worldwide,” added Hambrecht.

BASF intends to nominate a total of five directors for election to Engelhard’s Board of Directors at Engelhard’s upcoming Annual Meeting on June 2, 2006, in response to Engelhard’s announced plan to expand the Engelhard Board by three members to a total of nine members effective at the Annual Meeting. Two out of these five proposed nominees would replace two of Engelhard’s existing Board members whose terms expire at the Annual Meeting. The other three nominees would fill the vacancies created by the expansion of the Board.  If elected, the BASF nominees would constitute a majority of the nine-member Board and have the power, subject to exercise of their fiduciary duties, to facilitate the BASF tender offer and terminate Engelhard’s proposed leveraged recapitalization and 20 percent share buyback.

BASF has previously nominated Julian A. Brodsky and John C. Linehan to serve on the Engelhard Board of Directors.  BASF’s three new nominees are Arthur M. de Graffenried III, William T. Vinson and Stanford S. Warshawsky.  “Each of the BASF nominees is highly qualified to serve on the Engelhard Board and will act in accordance with their fiduciary duties to maximize value for the Engelhard shareholders.  Clearly, we believe that this will lead them to facilitate the BASF offer and terminate Engelhard’s proposed leveraged recapitalization and 20 percent share buyback.  When the Engelhard shareholders elect our nominees, they will have spoken in favor of that result,” said Dr. Hambrecht. “If Engelhard’s shareholders don’t vote in favor of our nominees, we will allow our tender offer to expire on June 5 and turn our attention to other opportunities,” added Hambrecht.

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 28, 2006, a total of 654,238 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 June 5, 2006, unless the offer is further extended.

BASF reserves the right to conduct a consent solicitation to expand the size of Engelhard’s Board to twelve and elect six BASF nominees to the resulting vacancies if BASF determines that it would be advisable to do so to ensure that Engelhard shareholders have the unfettered opportunity to choose between BASF’s all-cash offer and Engelhard’s leveraged recapitalization and 20 percent share buyback on a timely basis.
