In addition, each option to purchase Tradex Common Stock outstanding at the time of the Merger under the Tradex's stock option plans was converted into an option to purchase the number of shares of Ariba Common Stock equal to the number of shares of common stock of Tradex subject to such option multiplied by the exchange ratio for the Merger, and the associated exercise price was adjusted accordingly. ITEM 5. OTHER EVENTS. On March 2, 2000, the board of directors of Ariba authorized a two-for-one stock split to be effected in the form of a stock dividend.
