Laguna Hills, California, and Reston, Virginia - April 21, 2004 - Interchange Corporation, the leader in local paid search technology, and eStara, Inc., announced today they have formed a strategic partnership to provide click to call services powered by eStara to local advertisers via Interchange's suite of groundbreaking Local Direct^TM paid search products and services, available at localdirect.epilot.com.

eStara's click to call service - Push to Talk - will be integrated into Interchange's Local Direct paid search suite of products and services, a powerful local search platform made available to Internet and printed Yellow Pages publishers (IYP/YP). The combination will give advertisers a proven lead generation tool and drive incremental revenue for IYP/YP publishers.

"We are very pleased to provide additional value to our IYP/YP partners by offering the most comprehensive performance-based local paid search platform available," stated Heath Clarke, Interchange CEO. "Partnering with eStara to provide a world class click to call product is a natural extension of our core mission of connecting businesses with consumers."

eStara Push to Talk is the most widely deployed click to call service in the world. Push to Talk gives internet search customers the ability to click a button and speak with an advertiser immediately from the Web. In a recent online survey of over 5,000 eStara Push to Talk users, 25% said the service "saved" them from abandoning a Web transaction and looking for a competitor. eStara customers report an average increase in online sales of 45% after adding the click to call service to their website and online marketing and advertising tools.

"eStara is looking forward to this strategic partnership with Interchange," said Tom Natelli, eStara Chairman and CEO. "The integration of Push to Talk and Local Direct will create new revenue opportunities for online publishers, improve the search experience for consumers and drive additional high value leads to local advertisers."

eStara Push to Talk is a proprietary fully-hosted service that requires no additional hardware or software investment by advertisers or directory users. Website visitors can connect to advertising businesses by using the "click to call" service either through a Phone-to-Phone or PC-to-Phone connection.
