Accipiter's AdManager Selected to Serve Millions of Online Ads During Sixth Season of Big Brother Australia; Top-Rated Reality TV Show the Latest to Take Advantage of Accipiter-Hostworks Partnership in Asia-Pacific Region.

RALEIGH, N.C. & LONDON -- Accipiter Solutions, Inc., an online advertising technology innovator since 1996, continues to expand its presence in the Asia-Pacific region by signing Endemol Southern Star, producer of Big Brother. Endemol Southern Star is using Accipiter's AdManager technology to serve millions of online ads during the sixth season of the hit reality television series.

This past fall, Accipiter announced its partnership with Hostworks (ASX:HWG) as its Asia-Pacific ad management solution supplier. Hostworks is Australia's leading critical application managed service provider which provides 24x7 managed outsourcing services for many of Australia's leading online properties. This latest deal demonstrates that the partnership continues to build momentum in the booming $620M Australian online advertising sector. Current ad serving clients represent the top three online advertisers in the region in 2005 and include ninemsn, News Interactive, realestate.com.au, and Sensis MediaSmart. Collectively, clients using the AdManager solution are contracted to serve more than 3.5 billion ads per month.

Big Brother offers one of Australia's richest online media experiences, attracting big-spending consumers, aged 16-39 years, with live video streaming from the Big Brother house 24 hours a day, hundreds of "video on demand" segments and a vast range of images from "the House". In 2005, Hostworks successfully met a doubling of online demand for the Big Brother website, with page impressions jumping from 94 million in 2004 to more than 170 million. Every served page contains advertising while ads are also inserted into video streams coming from the House.

Ms Sam Hall, General Manager of Interactive for Endemol Southern Star, said Accipiter-Hostworks had the only ad management solution that met Big Brother's needs. "We initially chose a competitive solution, but found it was unable to deliver mid-stream ads or ads of various lengths," she said. "AdManager is able to deliver advertisements in the middle of a video stream and it can deliver ads of any required length."

Online advertising is a booming area of Internet activity as broadband continues to reach into Australian homes and businesses. The Audit Bureau of Verification Services confirms the Internet as Australia's fastest-growing advertising medium by reporting 2005 online advertising revenues jumped 59.8% to $620m, after a 64% increase during 2004.

Accipiter's vice president of sales, Jeff Wood, said winning Big Brother's business was another demonstration of the market leadership of the Hostworks-Accipiter partnership in the region. "The message is clear that the most successful online advertisers choose AdManager," he said.
