Renaissance Learning, Inc. Receives Unsolicited Non-Binding Proposal for
$15.50 Per Share in Cash

WISCONSIN RAPIDS, WI — August 24, 2011 — Renaissance Learning, Inc. (Nasdaq: RLRN), a leading provider of technology-based school improvement and student assessment programs for K-12 schools, announced today that it received an unsolicited, non-binding proposal from Plato Learning, Inc. (“Plato Learning”).  The proposal contemplates the acquisition of Renaissance Learning by Plato Learning for $15.50 per share in cash.  The proposal also states that it is subject to completion of due diligence and that the transaction is expected to be financed with equity from Thoma Bravo, HarbourVest Partners and JP Morgan as well as with debt.  

The Board of Directors has determined in good faith, after consultation with its financial advisor, that the Plato Learning proposal could reasonably be expected to lead to a Superior Proposal under the terms of the merger agreement entered into on August 15, 2011 with a company formed at the direction of investment funds (“Permira Funds”) advised by Permira Advisers LLC.  The Board of Directors expects to enter into a confidentiality agreement with Plato Learning, Thoma Bravo, HarbourVest Partners and JP Morgan and to provide information to and conduct negotiations with those parties.

There can be no assurance that Plato Learning will be able to obtain financing for a transaction with Renaissance Learning, or on what terms such financing may be obtained, that the Plato Learning proposal will lead to a Superior Proposal, or that Renaissance Learning will enter into a definitive agreement with Plato Learning.  The Board of Directors continues to recommend that shareholders vote in favor of adopting and approving the merger agreement and the transactions contemplated thereby with affiliates of the Permira Funds, pursuant to which Renaissance Learning would be acquired for $14.85 per share in cash.

Renaissance Learning also announced that the Board of Directors received a letter from counsel to Permira Advisers LLC asserting the view that the Plato Learning proposal does not represent a proposal that the Board of Directors could determine in good faith could reasonably be expected to lead to a Superior Proposal under the merger agreement.
