BASF Reaches Agreement to Buy Degussa's Construction Chemicals Business

    --(BUSINESS WIRE)--

    --  Transaction value EUR 2.7 billion for BASF

    --  Attractive forward integration for BASF

    --  4 to 5 percent annual growth in global construction chemicals
        market

    BASF Aktiengesellschaft, Ludwigshafen, reached an agreement with
Degussa AG, Dusseldorf, to acquire Degussa's construction chemicals
business. The purchase price for equity is just under EUR 2.2 billion.
As a result, the transaction value for BASF is EUR 2.7 billion. The
transaction, which still requires approval from the relevant
authorities, is expected to close by the middle of 2006.
    "Degussa's construction chemicals unit has an excellent position
in the industry and offers BASF an attractive means of forward
integration in its existing value chain in construction chemicals,"
said Dr. Andreas Kreimeyer, member of the Board of Executive Directors
of BASF Aktiengesellschaft, responsible for the Performance Products
segment. "The acquisition allows us to tap into the growth potential
of the construction chemicals market on a sustainable basis and will
further expand our position in this high-yield industry."
    The global construction chemicals market is valued at around EUR
13 billion and is attractive in view of annual growth of about 4 to 5
percent, relatively stable margins and high potential for innovation.
The acquisition of Degussa's business will give BASF rapid access to
additional industrial customers and end-users. BASF's strong presence
in Asia will additionally generate interesting growth opportunities in
this region's booming construction sector.
    By combining its own chemical expertise with Degussa's know-how in
construction chemicals applications, BASF will provide its customers
with innovation at the highest level and help them to be more
successful in the competitive construction sector. "We rely on the
expertise of the employees at Degussa construction chemicals as well
as our existing workforce, and are looking forward to forming the best
team in the construction chemicals industry," said Kreimeyer.
    In fiscal 2004, Degussa's construction chemicals division posted
sales of approximately EUR 1.8 billion and an EBIT of EUR 201 million,
with a global workforce of about 7,400 employees. As the market and
technology leader as well as the largest supplier of construction
chemical products, the division markets about 40,000 products
worldwide and is organized in two segments - Admixture Systems and
Construction Systems.
    The business units in the Admixture Systems segment offer products
and system solutions for the concrete industry. Customers include
manufacturers of ready-mix and precast concrete and concrete products
as well as contractors engaged in paving, mining and underground
construction. The technologies used in Admixture Systems' products
ensure optimal concrete properties.
    The business units in the Construction Systems segment are active
in the areas of building systems, flooring applications, coatings and
facades and expansion joints. Customers include building trade
businesses, fabricators, building contractors and dealers specializing
in concrete and masonry renovation, waterproofing, sealing, adhesive
systems, tile fixing, performance flooring, coatings and facades,
exterior insulation and expansion joints.
    BASF supplies chemical precursors to the construction chemicals
industry, in particular to formulators of construction chemical
products. Functional polymers from BASF improve the flow properties of
concrete, protect its surface, or are used in concrete repair systems.
Other applications for functional polymers are adhesives for flooring
and tiling, sealants, water vapor barriers and primers. Functional
polymers are also used in phase-change materials (PCMs) for indoor
temperature management. Other construction chemicals from BASF include
wood coatings and polyurethane systems for installation purposes.
    BASF is the world's leading chemical company: The Chemical
Company. Its portfolio ranges from chemicals, plastics, performance
products, agricultural products and fine chemicals to crude oil and
natural gas. As a reliable partner to virtually all industries, BASF's
intelligent system solutions and high-value products help its

42.7 billion. BASF shares are traded on the stock exchanges in

previously been scheduled to expire at 5:00 p.m., New York City time,
on Friday, March 3, 2006.

of Engelhard's stockholders," said Michael Grabicki, a spokesman for
BASF Aktiengesellschaft.
    BASF also announced that, as of March 3, 2006, it had received
anti-trust clearance from all major regulatory agencies necessary for

the offer, that, as of 5:00 p.m., New York City time, on March 3,
2006, a total of 649,277 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, March 17, 2006, unless the offer is further extended.
