Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On February 1, 2011, Blackbaud, Inc., a Delaware corporation (“Blackbaud”), Public Interest Data, Inc., a Virginia corporation (“PIDI”), all of the stockholders of PIDI (the “Stockholders”) and Stephen W. Zautke, as the representative of the Stockholders, entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) providing for the acquisition of PIDI by Blackbaud for approximately $17.5 million, plus an additional amount of up to $2.5 million in contingent payments based upon performance of the acquired business through the two-year anniversary of the transaction.

Pursuant to the Stock Purchase Agreement and upon the terms and subject to the conditions thereof, Blackbaud purchased all of the outstanding shares of PIDI’s common stock at an aggregate price of $17.5 million, subject to certain adjustments set forth in the Stock Purchase Agreement (the “Purchase Price”). $1.85 million of the Purchase Price will be held in escrow to fund certain post-closing purchase price adjustments and to secure PIDI’s former Stockholders’ obligations to indemnify Blackbaud for breaches of representations, warranties or covenants in the Stock Purchase Agreement.

The Stock Purchase Agreement contains representations and warranties that the parties made to, and are solely for the benefit of, each other. The assertions embodied in the representations and warranties made by PIDI in the Stock Purchase Agreement are qualified in information contained in a confidential schedule of exceptions that PIDI delivered to Blackbaud in connection with signing the Stock Purchase Agreement. Accordingly, investors and security holders should not rely on the representations and warranties as characterizations of the actual state of facts, since they were made only as of the date of the Stock Purchase Agreement and the representations and warranties of PIDI are modified by the underlying schedule of exceptions. Moreover, information concerning the subject matter of such representations and warranties might change after the date of the Stock Purchase Agreement.

The foregoing description of the Stock Purchase Agreement is qualified in its entirety by reference to the complete text of the Stock Purchase Agreement, a copy of which is to be filed as an Exhibit to Blackbaud’s Quarterly Report on Form 10-Q for the quarter ending March 31, 2011. The above summary is qualified in its entirety by reference to the Stock Purchase Agreement.
