(OTC:ADST) (BULLETIN BOARD: ADST) today announced an agreement in principle to acquire Relevantis in an all-stock transaction. The acquisition underscores AdStar's commitment to reposition itself as a full service supplier of mobile advertising solutions and adds important proprietary technologies for mobile advertising applications and infrastructures. Relevantis' technology includes the Universal Ad Platform, the first unified ad platform to support contextual mobile web and in-application advertising; and the Relevantis Relevancy Engine, a patent-pending system that models user activity and accurately predicts consumer behavior towards relevant advertisements. The combination of AdStar's Mobile Advertising Dashboard and the Relevantis ad platform provides an end-to-end solution that will allow publishers to monetize their mobile properties through advertising.

Relevantis CEO Scott Searle will become senior vice president and chief strategy officer at AdStar, and the companies expect the acquisition, the specific terms of which were not announced, to be complete in early May 2008. "It is with a great deal of excitement that we announce the agreement in principle to acquire Relevantis," said Leslie Bernhard, president and chief executive officer of AdStar, Inc.

Recently, Relevantis has introduced a number of industry 'firsts,' including the first advertising platform to support paid icons for interactive maps and navigation systems; the first to enable highly interactive AJAX advertisements on mobile phones; and the first advertising solution to support Android, Google's mobile phone operating system." Leslie continued, "When we started working with Scott Searle and Relevantis, we quickly recognized the myriad opportunities that we could pursue by combining our two companies and complementary technologies.
