Item 4.

Purpose of Transaction

Merger Agreement

On May 29, 2008, Blackbaud, Eucalyptus Acquisition Corporation, a Delaware corporation and a direct wholly-owned subsidiary of Blackbaud (“Eucalyptus”), and Kintera entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the Merger Agreement, (i) Eucalyptus will commence a tender offer (the “Offer”) to purchase all of the outstanding shares of Common Stock at a price of $1.12 per share, net to the seller in cash (the “Per Share Amount”), and (ii) following the consummation of the Offer, Eucalyptus will be merged with and into Kintera (the “Merger”), with Kintera as the surviving corporation, all upon the terms and subject to the conditions set forth in the Merger Agreement. In the Merger, each remaining share of Common Stock will be converted into the right to receive an amount in cash equal to the Per Share Amount, without interest.

The description of the Merger Agreement in this Statement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is filed as Exhibit 4.1 hereto and is incorporated herein by reference.

Tender and Support Agreement

On May 29, 2008, as an essential condition and inducement to the willingness of Blackbaud and Eucalyptus to enter into the Merger Agreement, Blackbaud entered into a Tender and Support Agreement (the “Support Agreement”) with Kintera’s directors, executive officers and certain other stockholders (collectively, the “Stockholders”).

Pursuant to the Support Agreement, each Stockholder has agreed, among other things, to tender all shares of Common Stock beneficially owned by such Stockholder, together with any other shares of capital stock of Kintera acquired by such Stockholder during the term of the Support Agreement, whether beneficially or of record (collectively, the “Owned Shares”).

Each Stockholder has also agreed, until the termination of the Support Agreement, at any meeting of stockholders of Kintera or any adjournment or postponement or written consent in lieu thereof, to vote the Owned Shares as follows: (a) in favor of the adoption of the Merger Agreement; (b) against all of the following actions: any inquiry, proposal or offer from any person relating to, or that is reasonably likely to lead to, directly or indirectly (i) a merger, consolidation, tender offer, exchange offer, binding share exchange, joint venture, dissolution, recapitalization, liquidation, business combination or other similar transaction involving Kintera; (ii) the acquisition by any person in any manner of a number of shares of any class of equity securities of Kintera or any Kintera subsidiary equal to or greater than 15% of the number of such shares outstanding before such acquisition; or (iii) the acquisition by any person in any manner, directly or indirectly, of assets that constitute 15% or more of the net revenues, net income or assets of Kintera, excluding the Offer and Merger; and (c) against any other action that is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or adversely affect the Offer, the Merger or any other transactions contemplated by the Merger Agreement.

Each Stockholder also has granted to Blackbaud (or any nominee of Blackbaud) an irrevocable proxy and power of attorney with respect to the voting of the Owned Shares in connection with the Merger Agreement and certain related matters.

In addition, each Stockholder has agreed, until the termination of the Support Agreement, not to exercise any rights (including, without limitation, under Section 262 of the Delaware General Corporate Law) to demand appraisal of any Owned Shares in connection with the Merger. Each Stockholder has also agreed, until the termination of the Support Agreement, not to, other than as may be required by a court order, (a) assign or otherwise dispose of (including, without limitation, by gift, merger consolidation or reorganization), or enter into any contract, option or other agreement providing for the sale, transfer, pledge, encumbrance, assignment or other disposition of, or limitation on the voting rights of, any of the Owned Shares, or (b) grant any proxies or powers of attorney, deposit any Owned Shares into a voting trust or enter into a voting agreement with respect to any Owned Shares.

The Support Agreement terminates upon the earlier to occur of (a) September 15, 2008; (b) the amendment of the Merger Agreement (including but not limited to the conditions and other terms of the Offer) to provide that the consideration for the purchase of the Stockholders’ Owned Shares will be less than $1.12 per share or will not be paid in cash; (c) any other modification or amendment of the Merger Agreement (including but not limited to the conditions and other terms of the Offer) in a manner that is adverse to the interests of the Stockholders or any of them under the Merger Agreement (including but not limited to not only their interests as stockholders, but also their interests in the Merger Agreement as officers and directors to the extent any of them are serving or have served in such capacities), without regard to the limitation on third-party beneficiary rights in the Merger Agreement; or (d) termination of the Merger Agreement.

The description of the Support Agreement in this Statement does not purport to be complete and is qualified in its entirety by reference to the Form of Support Agreement which is filed as Exhibit 4.2 and incorporated herein by reference.

Item 5.

Interest in Securities of the Issuer

(a). As a result of the Support Agreement, Blackbaud may be deemed to have the power to vote 8,718,483 shares of Common Stock held by the Stockholders in connection with the Merger Agreement and certain related matters. Accordingly, Blackbaud may be deemed to be the beneficial owner of 8,718,483 shares of Common Stock in the aggregate, representing approximately 21.73% of the total outstanding shares of Common Stock as of May 23, 2008.

The calculation of the foregoing numbers of shares of Common Stock and percentages is based on (i) the number of issued and outstanding shares of Common Stock at May 23, 2008, as represented by Kintera in Section 4.2(a) of the Merger Agreement, (ii) the number of shares of Common Stock beneficially owned by the Stockholders as represented and warranted by the Stockholders in the Support Agreement. To Blackbaud’s knowledge, none of the other persons named in Item 2 above beneficially owns, within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), any shares of Common Stock or any other shares of capital stock of Kintera.

Except as otherwise expressly provided in the Support Agreement, Blackbaud is not entitled to any rights as a stockholder of Kintera as to any shares of Common Stock subject to the Support Agreement. This Statement shall not be construed as an admission by Blackbaud that it is, for purposes of Section 13(d) of the Exchange Act, the beneficial owner of any shares of Common Stock subject to the Support Agreement.

(b). Pursuant to the Support Agreement, Blackbaud may be deemed to have sole power to vote or to direct the vote of 8,718,483 shares of Common Stock.

The following information contained in this Item 5(b) with respect to the Stockholders consists of information contained in the representations and warranties of the Stockholders contained in the Support Agreement. While Blackbaud has no reason to believe that such information was not reliable as of its date, Blackbaud accepts responsibility only for accurately reproducing such information and accepts no further or other responsibility for such information. In addition, Blackbaud makes no representation or warranty with respect to the accuracy or completeness of such information or any representation or warranty, and the filing of this Statement shall not create any implication under any circumstances that there have been no events, or that there is no other information, including events or information not yet publicly disclosed by the Stockholders, as applicable, that may effect the accuracy or completeness of such information.

(c). Except for the Merger Agreement and the Support Agreement described in Item 4 above, no transactions involving the Common Stock were effected during the past 60 days by Blackbaud or, to the knowledge of Blackbaud, any of the other persons named in Item 2 above.

(d). To Blackbaud’s knowledge, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock beneficially owned by Blackbaud.

(e). Not applicable.
