PLATO LEARNING REPORTS PRELIMINARY FINANCIAL RESULTS FOR SECOND QUARTER ENDED APRIL 30, 2010

MINNEAPOLIS, MN – May 6, 2010 – PLATO Learning, Inc. (NASDAQ: TUTR), a leading provider of K–adult online learning solutions, today announced that it expects to report a net loss of between ($0.03) and ($0.05) per share for the second quarter ended April 30, 2010. These amounts include transactions costs of approximately ($0.04) per share related to its recently announced merger with Thoma Bravo, LLC, and a benefit of approximately $0.01 per share on the final liquidation and wind-up of its U.K. subsidiary.

Total orders for the quarter are expected to decline up to 27% compared to the second quarter of 2009. Revenues for the second quarter are expected to be approximately $15.5 million, or generally flat as compared to the same period last year.

David Smith, chairman of the board of directors of the Company, said, “Although the Company has typically not provided quarterly results on a preliminary basis, in view of the upcoming shareholder meeting to vote on the pending merger, the board believed it was appropriate to provide shareholders with this information as it became available.”

Vin Riera, PLATO Learning President and CEO, said, “Going into the year we expected our fiscal second quarter to be challenging with regard to profitability, even before consideration of merger-related costs. The decline in year over year order levels for the quarter was not anticipated and would have been less significant considering the number of large deals expected to close in the second quarter that have moved to the first weeks of the third quarter due to extended decision-making and approval processes many districts have implemented in the current budget environment. While our customers continue to work through the challenges presented by the current funding environment, they continue to evaluate solutions like ours that can often help them address their budget challenges. As a result, it is too early to determine the extent, if any, that our experience in the second quarter will continue into the upcoming buying season.”
