  Cabot Corporation Receives Royalties from Licensing Agreement with Michelin

Michelin to Employ Cabot’s Patented Elastomer Composite Process Technology in
                              Tire Applications

Business Wire

BOSTON -- January 29, 2013

Cabot Corporation (NYSE: CBT) announces that it has reached another key
milestone in its technology licensing agreement with Manufacture Francaise des
Pneumatiques Michelin for use of Cabot’s patented elastomer composite
technology in tire applications. Regular royalty payments to Cabot have now
begun and will extend through fiscal 2022.

Since 2008, Cabot has been working with Michelin to develop the technology and
manufacturing operations necessary to commercialize the technology in global
tire markets. Through this agreement, Michelin has exclusive rights to Cabot’s
elastomer composite process technology for tire applications and is entitled
to build and operate plants that utilize this technology.

“This royalty agreement is the continuation of a prosperous and long-term
relationship with Michelin, as well as a significant new business opportunity
for Cabot,” said Patrick Prevost, president and chief executive officer, Cabot
Corporation. “The agreement highlights Cabot’s technology leadership and deep
commitment to developing innovative solutions for the tire industry.”

Tire manufacturers are increasingly being challenged to improve tire
performances. Cabot’s elastomer composites technology enables new tire design
opportunities for Michelin.

Cabot’s patented technology uses liquid phase mixing rather than conventional
dry phase mixing to incorporate reinforcing agents such as carbon black into
elastomers. This technology delivers superior dispersion of reinforcing agents
such as carbon black within the elastomer, which creates composites that
display unique properties.

The same kind of elastomer composite technology utilized by Michelin is
available for non-tire applications directly from Cabot through its
Transfinity™ brand of elastomer composite products. Customers can use
Transfinity materials to engineer significantly longer lasting and/or smaller
products for demanding applications in the mining, defense, automotive and
aerospace industries.
