BASF Extends and Increases All-Cash Tender Offer to US$38 per Share

Ludwigshafen, Germany (ots/PRNewswire) -

- BASF proposes nominees for a majority of the Engelhard Board of
Directors

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
US$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. Jurgen
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.
