Item 8.01 Other Events.

On June 26, 2006, Interphase Corporation issued a press release announcing that six executive officers of the Company have established Rule 10b5-1 trading plans. Rule 10b5-1 plans permit insiders to sell fixed portions of their holdings over a designated period of time under prearranged written plans that are established at a time when they are not in possession of material non-public information. Such programs provide for regular selling of a predetermined, fixed number of Company shares subject to the market price of the shares exceeding the threshold set forth in the respective plan, in order to gradually diversify the individual’s investment portfolio, minimize the market effect of share sales by spreading them out over an extended period of time and avoid concerns about initiating transactions while in possession of material non-public information. A copy of the press release is attached hereto as Exhibit 99.1.
