The rights issued under the plan will become exercisable by shareholders other than a potential acquiror only following an acquisition by the acquiror, without prior approval by the Company's Board of Directors, of 20% or more of the Common Stock, or the announcement of a tender offer for 20% or more of the Common Stock. "Although the Company is not currently discussing any acquisition or merger proposal with any prospective buyer, the purpose of the plan is to encourage any prospective buyer to negotiate with the Company's Board before launching a hostile takeover. In this way, we believe we can best ensure that all shareholders receive equal treatment and a fair price in any business combination involving the Company," said Fourth Shift CEO M. M. Stuckey. The new purchase rights will be distributed as a non-taxable dividend on December 28, 1998. The rights will trade with the Common Stock. There will be no rights certificates issued unless the rights become exercisable. The rights will expire on December 16, 2008.
