Item 5. Other Events.

     On October 18, 1999, Insight Enterprises, Inc., a Delaware corporation
("Insight"), announced that it terminated the merger agreement between Insight
and Action Computer Supplies Holdings PLC, a company registered in England
("Action"), which was originally announced on May 10, 1999 and subsequently
revised on July 27, 1999, in light of the deterioration in Action's operating
results and the difficult near-term market conditions expected by Action related
to the slowdown in customer spending due to Year 2000 concerns.
