10. Shareholders' Equity - Restrictive Agreement

Messrs. Gerhard J. Neumaier, Frank B. Silvestro, Ronald L. Frank and Gerald A. Strobel entered into a Stockholders' Agreement in 1970 which governs the sale of certain shares of common stock owned by them, the former spouse of one of the individuals and some of their children. The agreement provides that prior to accepting a bona fide offer to purchase the certain covered part of their shares, each party must first allow the other members to the agreement the opportunity to acquire on a pro rata basis, with right of over-allotment, all of such shares covered by the offer on the same terms and conditions proposed by the offer.
