    <remarks>(1) The shares reflected in Table I are the shares issued upon exercise of a Rule 16b-3  Stock Option, which exercise was previously timely reported.  The acquired shares were inadvertently omitted from the prior report.  This amendment also corrects certain inadvertent mistakes in the reporting of the option exercise.</remarks>
