Albemarle and International Chemical Investors Announce

Letter of Intent Regarding Thann Facility

RICHMOND, Virginia and FRANKFURT, Germany—August 8, 2006—Albemarle Corporation (NYSE: ALB) and International Chemical Investors Group (“ICIG”) announced that they have signed a letter of intent (“LOI”) regarding the transfer of Albemarle’s facility in Thann, France. Under the terms outlined in the LOI, ICIG will acquire 100 percent of the stock of Albemarle France SAS and its subsidiary Albemarle PPC SAS, the owner of the facility.

“We are delighted having the opportunity to continue and expand operations at the Albemarle Thann site, which will complement our present portfolio of chemical assets, including the fine chemicals custom manufacturing operations of WeylChem. It is our intention to convert the KOH plant as soon as possible to membrane technology and to expand capacity,” says Dr. Achim Riemann, Managing Director of ICIG.

“We look forward to actively supporting the Thann business in its organic growth as well as through additional complementary acquisitions,” says Patrick Schnitzer, Managing Director of ICIG.

“We are working diligently to negotiate definitive agreements, obtain necessary consents and close the transaction as soon as possible,” said Matt Juneau, Regional Managing Director, Albemarle Europe. “We believe ICIG’s leadership and experience in this industry, combined with the dedicated and resourceful workforce at Thann, will provide for a smooth and orderly transition to the new owners.”

The LOI reflects the parties’ intent to conclude a definitive agreement in August 2006. Albemarle and ICIG cannot assure that the definitive agreement will be concluded within this time frame, or at all. Execution of the definitive agreement is contingent on agreement on all material terms and other customary closing conditions for transactions of this nature.
