Common use of Per Share Information Clause in Contracts

Per Share Information. Per share information is based on the weighted-average number of common shares outstanding during each period for the basic computation and, if dilutive, the weighted-average number of potential common shares resulting from the assumed conversion of outstanding stock options, warrants and convertible preferred stock for the diluted computation.
