Item 5. Other Events.

As previously disclosed in Acterna Corporation’s (“Acterna”) Quarterly Report on Form 10-Q for the period ended December 31, 2002, filed with the Securities and Exchange Commission on February 14, 2003, Acterna is in discussions with its senior lender group to restructure its existing long-term debt obligations (the “Senior Debt Obligations”). In connection with these discussions, Acterna did not make the scheduled quarterly payment of interest and other fees due on March 31, 2003, with respect to its Senior Debt Obligations. Under the terms of the credit agreement governing its Senior Debt Obligations, Acterna had a five day grace period before an event of default occurred. Accordingly, Acterna is in default of its Senior Debt Obligations. In the event that the senior lenders were to demand repayment, Acterna would be unable to make such repayment. Acterna is in continuing and constructive discussions with such lenders with respect to a consensual restructuring.

For more information on Acterna’s recent results of operations and liquidity and capital resources, please refer to Acterna’s Quarterly Report on Form 10-Q for the period ended December 31, 2002.

Item 7. Financial Statements and Exhibits.

None.
