Q&A Q&A

"Safe Harbor" Statement under the U.S. Private Securities Litigation Reform Act of 1995 This presentation contains forward-looking statements that are made in reliance upon the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. The forward-looking statements contained herein include statements about the consummation of the pending merger of JDA Software Group, Inc. ("JDA") and i2 Technologies, Inc. ("i2"), future financial and operating results of the combined company and benefits of the pending merger. Factors that could cause actual results to differ materially from those described herein include: (a) JDA's ability to leverage the i2 products to enable it to further expand its position in the supply chain market; (b) JDA's ability to successfully integrate and market the i2 products; (c) JDA's and i2' ability to obtain regulatory approvals; and (d) JDA's and i2's assumptions regarding the future financial and operating results of the combined company if JDA and i2 successfully complete the merger. Additional information relating to the uncertainty affecting the businesses of JDA and i2 as well as certain risk associated with the pending merger between JDA and i2 are contained in the respective filings with the SEC, including the Proxy Statement referred to below. Neither JDA nor i2 is under any obligation to (and expressly disclaims any such obligation to) update or alter its forward-looking statements, whether as a result of new information, future events or otherwise. In addition to the specific risks identified in the proceeding paragraph, mergers involve a number of special risks, including diversion of management's attention to the assimilation of the technology and personnel of acquired businesses, costs related to the merger, the integration of acquired products, technologies and employees into JDA's business and product offerings, and the risk that the merger is not consummated. Achieving the anticipated benefits of the pending merger will depend, in part, upon whether the integration of the acquired products, technology, or employees is accomplished in an efficient and effective manner, and there can be no assurance that this will occur. The difficulties of such integration may be increased by the necessity of coordinating geographically disparate organizations, the complexity of the technologies being integrated, and the necessity of integrating personnel with disparate business backgrounds and combining different corporate cultures. The inability of management to successfully integrate the business of the two companies, and any related diversion of management's attention, could have a material adverse effect on the combined company's business, operating results and financial condition.
