HOUSTON -- April 11, 2013

A consortium led by CSL Capital Management, LLC announced today it has sold
PyraMax Ceramics, LLC (“PyraMax”) to Imerys S.A. for a total consideration of
USD 235 million and additional payments of up to USD 100 million, subject to
meeting certain industrial and commercial performance criteria. PyraMax is in
the final stages of completing a state-of-the-art, 500 million pounds per year
manufacturing facility comprised of two production lines located in Wrens, GA.

Imerys’ acquisition of PyraMax, added to its current production capacity, will
significantly enhance its ability to supply high-quality ceramic proppant to
the fast-growing North America non-conventional oil and gas market.

Charles S. Leykum, Founder of CSL Capital Management and Chairman of PyraMax
Ceramics, LLC, said “Our management team has done a great job building PyraMax
from a greenfield project to near commercial operation. We are excited to work
with Imerys, a well-established player in this sector, and think the
combination will create a robust supplier to the proppants industry. We wish
Don and his team continued success.”

Don Anschutz, President of PyraMax Ceramics, LLC, said “CSL has been an
invaluable partner and resource for us and we enjoyed working with them. Their
experience building companies and vision for PyraMax to be a state-of-the-art
ceramic proppant plant was essential to our success. Joining Imerys will
accelerate that vision and give us access to expertise and resources that will
increase our ability to anticipate and exceed our customers’ expectations.”
