   . Caldera also purchased a paid-up license to continue bundling the
     Tarantella products Vision FS, TermLite and Webtop, which were bundled in
     SCO OpenServer and UNIXWare products prior to closure of last year's
     transaction.

   . Caldera will purchase 500,000 shares of Caldera stock from Tarantella for
     $555,100.
