Intrusion Inc. to Appeal Nasdaq Delisting Notification

Richardson, Texas – November 7, 2003 – Intrusion Inc. (NASDAQ: INTZ), (“Intrusion”) today announced that the Nasdaq Listing Qualifications Department has notified the Company that it had not regained compliance with the minimum $1.00 closing bid price per share requirement for continued listing pursuant to Marketplace Rule 4310(c)(4) by November 5, 2003.  As a result, the Company’s securities are subject to delisting from The Nasdaq SmallCap Market effective upon the opening of business on November 17, 2003.

Intrusion intends to appeal the Nasdaq Listing Qualifications Department determination before a Nasdaq Listing Qualification Panel.  During the appeals process, the scheduled delisting will be stayed and the Company’s common stock will continue to trade on the Nasdaq SmallCap Market, pending the Panel’s decision.  The hearing date has not been set and is yet to be determined by Nasdaq.  While there can be no assurance that the Company’s request for continued listing on the Nasdaq SmallCap Market will be granted, the Company is exploring all possible avenues to preserve the Nasdaq listing.
