Companies See Growth Opportunity in Local Advertising

PHILADELPHIA, PA (August 9, 2007) VoiceStar, Inc., a provider of industry-leading methods that make performance-based advertising a reality, today announced it had agreed to be acquired by Marchex, Inc. (NASDAQ: MCHX, MCHXP), a local online advertising company and leading publisher of local content.

The transaction is expected to close on October 1, 2007. Once completed, it will enable VoiceStar and Marchex to combine their product offerings and better serve customers.

"We are very excited to be joining forces and bringing the value of our combined assets to a greater audience," said Todd Lieberman, VoiceStar CEO. "We share Marchex's vision for unlocking growth opportunities in the local space and look forward to being a part of the innovative solutions Marchex brings to the marketplace."

With the acquisition, Marchex will have a clear leadership position in local online advertising by adding call-based services to its local online advertising platform, making it one of the most comprehensive offerings available, and expanding Marchex's base of local advertisers and large aggregators.

"With the addition of VoiceStar, Marchex offers one of the most comprehensive online advertising platforms and agency services for local advertisers at scale in the industry. We can now offer local aggregators a private label search- and call-based marketing platform with distribution for their advertisements in search engines, vertical Web sites, and on our network of local Web sites," said Peter Christothoulou, Marchex Chief Strategy Officer. "Additionally, we can now also add proprietary pay-per-phone-call advertising units to our network of local Web sites, which allows us to increase the direct monetization of our own properties."
