PRINCETON, N.J. -- January 10, 2013

Rockwood Holdings, Inc. (NYSE: ROC) today announced that its Board of
Directors has authorized the Company to repurchase shares of Rockwood common
stock up to an aggregate of $400 million. The Company intends to effectuate
these repurchases in 2013.

Seifi Ghasemi, Chairman and Chief Executive Officer, said, “Based upon the
strength of our balance sheet and our ability to generate cash, the Board has
authorized the stock repurchase program. This approval demonstrates our strong
belief that the current Rockwood share price offers outstanding value and will
enable us to use some of our existing cash to unlock value for our
shareholders.”

transactions, unsolicited or solicited privately negotiated transactions,
accelerated share repurchase programs or other derivative transactions, self
tender offers, or through any combination of the foregoing, or in such other
manner as determined by the Company. The timing of the repurchases and the
actual amount repurchased will depend on a variety of factors, including the
market price of the Company's shares, general market and economic conditions,
and other factors. The share repurchase program may be extended, suspended or
discontinued at any time without notice.
