InfoSpace Signs Software Deal

Updated from 9:26 a.m.

InfoSpace ( INSP) fell 10% Monday, even after setting a partnership with closely held New York software developer Amplify.

The companies said InfoSpace will provide a Web search feature for Amplify's companion toolbar and a search component for Amplify's Web site. Amplify said its companion toolbar is the only search tool that lets users search the Web as well as search for Amps, unique Web collections created by Amplify users directly from their browser.

"As we embark on changing how Web users capture and share information, it was critical to integrate a reliable and proven search component into Amplify's companion toolbar, as well as the Web site's search feature," said Amplify CEO Eric Goldstein. "InfoSpace's expertise and reputation in the search field made them an optimal choice."

On Monday, InfoSpace fell $3 to $27.96.
