CLEVELAND - May 8, 2000 - The Geon Company (NYSE: GON) and The M.A. Hanna
Company (NYSE: MAH) announced today that they will join forces to create the
world's largest polymer services company. The two companies intend to
consolidate their global operations into a new organization, demonstrating
leadership in consolidating the specialty chemical industry.

The new company will have initial annual revenues of approximately $3.5 billion,
with anticipated market capitalization well above $1 billion. Closing is
anticipated in August. It is expected that shares of the new company will be
listed on the New York Stock Exchange. The consolidation is subject to approval
by shareholders of both companies and regulatory approvals.

The combination brings together two companies with complementary strengths and
common strategies to become a world leader in performance polymers and services
- - linking Geon's operating strengths with M.A. Hanna's experience in
multi-polymer compounding, colorants and distribution. The new company's strong
balance sheet will allow it to pursue an aggressive acquisition strategy.

Under a definitive consolidation agreement approved by the companies' boards of
directors at special meetings yesterday:

  -  Phillip D. Ashkettle, 54, will be chairman and chief executive officer of
     the combined company, and Thomas A. Waltermire, 50, will be president and
     chief operating officer. Under a transition plan, Waltermire will become
     CEO on January 1, 2002, and chairman at the 2004 annual shareholder
     meeting.

  - The consolidation will take place in the form of a cashless stock swap.

   - The companies have agreed on fundamental strategies and are committed to
     achieving at least $50 million in operating earnings improvement annually
     from raw materials savings, market-related opportunities and overhead
     reductions by 2002.

  -  The corporate headquarters will be consolidated at a new site in Greater
     Cleveland that is yet to be determined. The new company will have more than
     10,000 employees, 80 manufacturing sites and an extensive distribution
     network worldwide.

  -  The new organization will begin immediately to develop a new name.

"The strengths of our existing companies complement one another remarkably well,
especially in major markets served," said Ashkettle, currently chairman,
president and chief executive officer of M.A. Hanna. "We were attracted to
Geon's strengths in vinyl materials, operations, information technology and
e-commerce. Together we can go to market with a breadth of technologies and
services that is second to none, creating the leadership position in every area
in which we operate."

Waltermire, now Geon's chairman and chief executive officer, added, "M.A. Hanna
brings just what Geon needs to grow - size, multi-polymer based products, and
strong international presence. In addition, we share similar business
philosophies in key areas, such as customer-focused teams, value-added selling
and aggressive growth. We believe the combination of our two strong
organizations creates an outstanding opportunity for our customers, employees,
suppliers and shareholders."

Ashkettle will have principal responsibility for corporate direction, external
relations and mergers and acquisitions. Waltermire will be responsible for
operations, organic growth, most corporate staff functions and e-business
strategies.

"Acquisitions remain a key element of our strategy," said Ashkettle. "In this
consolidating industry, there are a lot of opportunities to add value for
customers and shareholders of the combined company. We will be in a much
stronger position as the consolidator of choice to expand our business portfolio
and strengthen our global presence."

Waltermire added, "This combination enhances our ability to create a world-class
polymer services business focused on growth with solid margins and made up of a
network of closely aligned business teams. We believe the new company will bring
an unmatched capability to help our customers become more profitable. By
combining both Hanna's and Geon's developing e-commerce capabilities as well as
creating customer-focused teams, we will make already good customer service even
better."

The new board of directors will consist of 10 external members selected equally
from the current boards in addition to Ashkettle and Waltermire. Current member
of Geon's board joining the new company board are: James K. Baker, Gale
Duff-Bloom, J. Douglas Campbell, D. Larry
