PHILLIP ASHKETTLE STEPS DOWN AS CEO OF M.A. HANNA

GEON CEO THOMAS WALTERMIRE WILL HEAD POLYONE;
MERGED COMPANY REMAINS ON TRACK FOR SEPTEMBER 1 LAUNCH

Cleveland, August 16, 2000 - M.A. Hanna Company (NYSE: MAH; CHICAGO) Board of
Directors announced today that, effective immediately, Phillip D. Ashkettle has
stepped down as chairman, chief executive officer and president, and as a
director.

With Ashkettle's departure, Chairman and CEO Thomas A. Waltermire of The Geon
Company (NYSE: GON) will become chairman and CEO of PolyOne Corporation, the new
company being created from the combination of M.A. Hanna and Geon.

The M.A. Hanna board named as interim chairman David H. Hoag, retired chairman
of LTV Corporation and an M.A. Hanna director. Garth W. Henry, executive vice
president of international operations for M.A. Hanna, was named interim
president and CEO. Both men will serve until PolyOne becomes operational. Carol
A. Cartwright, Ph.D., president of Kent State University and an M.A. Hanna
director, will replace Ashkettle on the PolyOne Board of Directors.

Ashkettle's departure will have no effect on the formation of PolyOne, which is
expected to begin operations September 1, assuming a favorable vote by
shareholders of both companies on August 29.

Under the consolidation agreement announced May 8, Ashkettle would have filled
the top position at PolyOne and Waltermire would have been president and chief
operating officer of the new company. Waltermire would have succeeded to the CEO
position in 2002, and to the chairmanship in 2004.

Hoag said the M.A. Hanna board has full confidence in Waltermire, and reaffirms
its commitment to proceed with the consolidation.





"The integration process is off to a great start," Hoag said. "And, as PolyOne
has taken shape, I have been struck by Tom's strong leadership skills, his
energy and his enthusiasm for challenges. So now we move forward, excited about
the potential of PolyOne."
