This Presentation is subject to updating, completion, revision, verification and further amendment. None of ATA, Rally, or their respective affiliates has authorized anyone to provide interested parties with additional or different information. Nothing herein shall be deemed to constitute investment, legal, tax, financial, accounting or other advice.

In connection with the proposed Transaction, ATA expects to form a new Delaware corporation ("Pubco"), which, in turn, will form two wholly-owned subsidiaries, "Purchaser Merger Sub" and "Company Merger Sub." At the closing of the proposed Transaction, ATA, after continuing out of the Cayman Islands and into the State of Delaware as a Delaware corporation, will merge with Purchaser Merger Sub, with ATA surviving such merger, and the Company will merge with Company Merger Sub, with the Company surviving such merger. After the closing, the former security holders of ATA and of the Company, respectively, will be hold or be entitled to receive securities of Pubco. Investment in Pubco securities has not been approved or disapproved by the U.S. Securities and Exchange Commission (the "SEC"), nor has any authority passed upon or endorsed the merits of the Transaction, the securities or the accuracy or adequacy of this Presentation. Any representation to the contrary is a criminal offense.

Each recipient of the information and data contained in this Presentation should perform its own independent investigation and analysis of the Transaction and the value of the Company. The information and data contained herein are not a substitute for a recipient's independent evaluation and analysis. In making an investment decision, prospective participants in an offering of securities must rely on their own examination of the Transaction and the Company, including the merits and risks involved. Prospective participants are urged to consult with their own legal, tax, investment and accounting advisers with respect to the consequences of an investment. If any portion of this Presentation is inconsistent with or contrary to any of the terms of definitive documents related to the Transaction, the terms of such agreements shall control. You should consult with your own advisors as needed to assist you in making your investment decision and to advise you whether you are legally permitted to purchase Pubco securities. The provision of this Presentation shall not be taken as any form of commitment on the part of ATA or the Company to proceed with any negotiations or transactions, and each of ATA and the Company reserves the right to discontinue discussions or negotiations regarding any transaction at any time for any reason or no reason. 2
