Huntsman and Zamil Group Proceed to Next Phase of New Morpholine and Diglycolamine® Agent Joint Venture in Saudi Arabia

EVERBERG, BELGIUM – Huntsman Corporation (NYSE:HUN) and Zamil Group Holding Company today announced they are proceeding to the next stage of their previously-announced feasibility study for a new morpholine and Diglycolamine® Agent (DGA) amines joint venture facility in Jubail, Saudi Arabia.

The planned joint venture, first announced 12 months ago, would operate the proposed plant on a 50:50 basis and would use technology licensed from Huntsman, with Huntsman also having the rights to global sales and marketing of products produced at the plant.

This final stage of the feasibility study includes detailed, front-end engineering plans and financial estimates and should be ready by mid-2011.  Plant start-up is currently slated for the second quarter of 2014, subject to plan agreement by both parties.

Peter Huntsman, President and CEO of Huntsman Corporation said: “This significant planned investment would not only make Huntsman the most global supplier of DGA and morpholine but  would also complement and extend our developing business footprint in the Middle East.”  He added: “The Zamil Group Holding Company is a major petrochemicals and chemicals player in the region and we are absolutely delighted to be working with them again.”

Mr. Fahad Al-Zamil, President of Zamil Group Holding Company/Jubail Operations, said: “Our company manages a very wide range of innovative and high quality products and this joint venture testifies to the importance we give to high value-added chemicals in our portfolio.”  He added: “We have many partnerships with Huntsman Corporation and we look forward to continuing to build on the successes of the past.”
