Unica Corporation Announces Date of Fourth-Quarter and Fiscal Year Ended 2008 Financial Results Release, Conference Call and Webcast

WALTHAM, Mass., Nov 26, 2008 -- Unica Corporation (Nasdaq: UNCA), a leading global provider of enterprise marketing management (EMM) solutions, today announced that it will report its final fourth-quarter and fiscal year ended 2008 financial results before the U.S. financial markets open on Monday, December 1, 2008.

As disclosed previously, the Company delayed its originally scheduled release date of November 13, 2008 in order to finalize its results pending its review of a potential issue relating to its recording of maintenance and subscription revenue. Although the Company is still in the process of completing its review, it currently believes that it will record an adjustment in the fourth quarter of fiscal year 2008 to increase revenue in the range of $325,000 to $425,000 as a result of correcting this issue. The Company does not expect that it will be required to restate any prior period results.

In conjunction with the scheduled earnings announcement, Unica will host a conference call on Monday, December 1, 2008 at 8:00a.m. ET to discuss the company's financial results.
