Polycom Huntsman. He was promoted by Spartech to Executive Vice President of

of Color and Specialty Compounds and Molded and Profile Products in May of 2004.
In April of 2005 he added the responsibility for International Operations. Mr.

replacing Mr. Buechler, who has resigned from the Board incident to his
retirement.

         "I am very proud of what Spartech has accomplished since I joined it in
1981 and I strongly believe that George Abd is an excellent choice to lead
Spartech in its next phase of growth," Mr. Buechler said.

         Jackson W. Robinson, age 63, has been appointed Chair of Spartech's
Board, replacing Mr. Buechler. Mr. Robinson most recently served as the Board's
presiding Director.

         Mr. Robinson noted that the appointment of Mr. Abd was the result of
succession planning discussions which the Board had been conducting for some
period of time. "We are very fortunate to have someone of George




Abd's caliber available to us," Mr. Robinson commented. "We believe that he
brings the skill set required at this stage of Spartech's development to address
its challenges and to energize its personnel." Mr. Robinson continued by saying
that "George will continue to work with the very talented management team which
Brad has assembled."

         "Brad has made extraordinary contributions during his tenure at
Spartech," said Mr. Abd. "I have seen this Company under his leadership
transformed into a global processor of engineered thermoplastics. I look forward
to building on his success," he added.

         Spartech Corporation is a leading producer of engineered thermoplastic
materials, polymeric compounds, and molded & profile products, which following
its recently announced plant restructuring plan, will have 47 facilities located
