ITEM 5. OTHER EVENTS.

     On February 25, 2003, we elected to terminate our unsecured revolving
credit facility that we had maintained with a syndicate of banks since May 2000.
The $100.0 million credit facility was due to expire on May 31, 2003. There were
no borrowings against the credit facility on February 25, 2003. We have not
borrowed against the credit facility in fiscal 2003, nor did we borrow against
the credit facility in fiscal 2002.

     The credit agreement was filed as Exhibit 10.10 to our annual report on
Form 10-K for the fiscal year ended March 31, 2000.
