President and Chief Executive Officer -- $675,000; Lynn A. Brooks, President,
Rieke Packaging Systems -- $271,000, Scott D. Hazlett, President, Cequent

depreciation and amortization (EBITDA) for the 2004 fiscal year compared to
budget; (2) the individual executive officer's contribution to those results;
and (3) the individual executive officer's achievement of personal performance
objectives.
