AI&P Customer Letter

Dear Customer,

As you may have seen, Albemarle recently announced an agreement to acquire Rockwood Holdings, a leading global developer, manufacturer and marketer of specialty chemicals. You can view the press release we issued here.

As I am sure you remember, earlier this year, Albemarle announced a separate agreement to sell our antioxidants, FDA-regulated ibuprofen and propofol businesses and assets to SI Group, a leading global developer and manufacturer of chemical intermediates, specialty resins, and solutions. As a customer of that business segment, we felt it was important to reach out and provide you with an update given our announcement to acquire Rockwood.

Currently, our previously announced asset sale to SI Group is proceeding as planned and we continue to expect it to close later this year. We don’t anticipate that the recent announcement concerning Rockwood will have any impact on our transaction with SI Group or our ability to continue meeting your needs. If you have any questions about the Rockwood announcement or the transition to SI Group, please don’t hesitate to contact your Albemarle representative.

Sincerely,

/S/ Tom Thomas

Tom Thomas

Division Vice President Antioxidants
