Bob Hope Airport Upgrades to New Collaborative Version of PASSUR Community Relations Software

New Version of AirportMonitor Allows Airport to Communicate in Real Time

GREENWICH, Conn., June 8, 2007 — Megadata Corporation (OTC Bulletin Board: MDTA) announced today that Bob Hope Airport has upgraded their existing AirportMonitor software to the new collaborative version of PASSUR(R) AirportMonitor(TM), the airport industry's leading web-based airspace education tool for airport communities.

"This AirportMonitor enhancement has already made a difference," said Dennis O'Connor, Noise Compliance Officer for Bob Hope Airport. "Last week an Air Force plane made a low pass for a funeral and – immediately – the phones starting ringing. We quickly had the relevant information on AirportMonitor to explain what happened. We're really looking forward to using the enhanced version to keep our community informed."

"We're excited by these AirportMonitor innovations because it further bonds airports and their communities," said Jim Barry, President and CEO of Megadata, which owns PASSUR. "We believe collaboration is key in all aspects of aviation – and we're particularly pleased to help airports and their constituents with this breakthrough product."

AirportMonitor is the pioneering community airspace awareness tool, which provides an interactive display of air traffic and flight information in and around the terminal airspace, designed for airport websites. It enables residents to view traffic in "near-live" and replay mode, with a host of user-friendly online tools designed to promote airspace education, answer questions about specific flight behavior, and promote openness and trust between residents and the airport.

The new version of AirportMonitor, a patented product, includes:

— Instant airport messaging – based on the existing collaborative decision making technology developed for PASSUR Portal(TM) and OPSnet(TM), this allows the airport to instantly communicate about airspace conditions which may be affecting residents' noise quality. Management of these messages is easily done through PASSUR online password access messaging tools, requiring no Airport IT involvement.

— "My Home Locator" – providing AirportMonitor users the ability to pinpoint their home on the AirportMonitor background map by entering their address, allowing for a more effective assessment of airspace and flight activity in relation to the user's residence.
