Rohm and Haas and Tasnee and Sahara Olefins Company Form Joint Venture to Make Acrylic Monomers in Jubail, Saudi Arabia



    Rohm and Haas Company (NYSE:ROH) and Tasnee Sahara Olefins Company
    (TSOC) of Saudi Arabia said today they will form a joint venture which
    will produce 250,000 metric tons of acrylic acid and related esters in
    Jubail, Kingdom of Saudi Arabia, beginning in 2011. These feedstock
    materials will be used primarily to support the fast-paced growth of
    Rohm and Haas´s water-based acrylic products in rapidly developing
    economies. TSOC will have exclusive rights to sell a portion of the
    acrylic acid products within the Gulf Cooperation Council countries of
    Saudi Arabia, Bahrain, Qatar, Oman, Kuwait and the United Arab
    Emirates.

    "This is a wonderful day for Rohm and Haas," said Carol Eicher

    Vice President and Business Director for the company´s Primary
    Materials business. "This joint venture - Saudi Acrylic Monomer
    Company - demonstrates our commitment to secure monomers at the right
    place, at the right time, and at the right cost - in support of the
    ongoing global growth of our acrylic portfolio." Eicher noted that the
    Jubail facility is the first downstream chemical project of its kind
    to be undertaken in the Middle East.

    Saudi Acrylic Monomer Company will be 75 percent owned by TSOC; 25
    percent by Rohm and Haas. Rohm and Haas will invest approximately $50
    million for its equity stake in the venture, and will license its
    technology for making acrylic acid. When completed, the plant in
    Jubail will employ approximately 225 people.

    Rohm and Haas will consume the majority of the plant´s production
    to supply the needs of the company´s downstream businesses to make
    products used in paints and coatings, adhesives, caulks, sealants

    plastics additives, detergents additives and in industrial
    applications, among others. Some of the plant´s production will also
    be allocated for sale to external customers. TSOC and Rohm and Haas
    will cooperatively market products to the Saudi, GCC, Middle East

    Asia and European regions.

    TSOC is comprised of Tasnee, one of the largest private industrial
    companies in the Kingdom of Saudi Arabia, and Sahara Petrochemical, a
    publicly traded Saudi joint stock company, with a history of
    developing petrochemical projects in Saudi Arabia.

    "We are pleased to be able to form this partnership with TSOC,"
    said Raj L. Gupta, Chairman, President and CEO of Rohm and Haas, an
    $8.9 billion specialty materials company. "These are well-known and
    highly regarded firms. We are looking forward to a long and prosperous
    relationship for all involved."

    methacrylates monomers. Its $2 billion Primary Materials business
