                not become employed, the Company shall pay the Employee
                additional supplemental severance pay in accordance with the
                next sentence. During the six-month period following the

                additional supplemental severance pay at a rate equal to the
                Employee's base compensation immediately prior to such
                termination and such additional supplemental severance pay shall
