~~The~~EXHIBIT ~~Merger Agreement contains certain termination rights for both Art Technology Group and~~INDEX Oracle, and provides that, upon termination of the Merger Agreement under specified circumstances, Art Technology Group may be required to pay Oracle a termination fee of $33,500,000, including if it accepts a superior acquisition proposal, or to reimburse Oracle for up to $5,000,000 of its out-of-pocket expenses in connection with the transaction.

The foregoing description of the Merger Agreement 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 2.1 hereto and is hereby incorporated into this report by reference. The Merger Agreement, which has been included to provide investors with information regarding its terms and is not intended to provide any other factual information about Art Technology Group or Oracle, contains representations and warranties of each of Art Technology Group, Oracle and Merger Sub. The assertions embodied in those representations and warranties were made for purposes of the Merger Agreement and are subject to qualifications and limitations agreed to by the respective parties in connection with negotiating the terms of the Merger Agreement, including information contained in confidential disclosure schedules that the parties exchanged in connection with signing the Merger Agreement. Accordingly, investors and security holders should not rely on such representations and warranties as characterizations of the actual state of facts or circumstances, since they were only made as of a specific date and are modified in important part by the underlying disclosure schedules. In addition, certain representations and warranties may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters of fact. Moreover, information concerning the subject matter of such representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Art Technology Group’s or Oracle’s public disclosures.
