  ITEM 5.  OTHER EVENTS.
  
  On October 9, 2001, Redback was served with notice that Arrow Electronics had
  commenced an action against the Company, seeking damages in excess of $54
  million relating to inventory procured and manufactured on behalf of the
  Company. On November 19, 2001, Arrow Electronics and the Company entered into an
  agreement to settle these claims, under which Redback will take possession of
  the inventory, and make payments over the next four quarters, guaranteed, in
  part, by a $28 million letter of credit. The settlement is not materially
  different from amounts the Company has previously reserved and accrued.
