November 5, 2009

Memorandum to All JDA Associates:

JDA announced today that it has entered into a definitive merger agreement with i2, through which it will acquire all of the outstanding equity of i2. We are very pleased that we were able to re-engage with i2 to create a company that will provide exciting opportunities for customers, shareholders and associates of the combined company.

The fact that we were not able to close the deal with i2 in the Fall of 2008 due to the impact of the global financial crisis was a great disappointment to us. We knew that this combination was the right move for both of us and that we would be creating a powerful company that would be a formidable competitor in the marketplace. We are pleased that conditions in the financial markets have stabilized, allowing us to establish a secure lender’s commitment, and giving us a very high degree of certainty that we will be able to successfully move forward with this acquisition.

The reasons that led JDA to seek to acquire i2 in 2008 are every bit as compelling today as they were last year. We firmly believe that the time is right to create a global leader in supply chain planning and execution. Consider the following:

• The economic crisis, and ongoing unpredictability of the global business environment, has created a strong focus on supply chain efficiency and effectiveness in the market. This acquisition positively positions us to respond to that focus.

• The acquisition of i2 brings to JDA innovative technologies and solutions and an extreme depth of domain and services expertise that will supplement JDA’s current solutions and unparalleled expertise.

• This combination of our two companies will result in the world’s largest software company focused on supply chain management and will enable accelerated innovation for our customers. Adding i2’s more than 500 customers and robust, patented manufacturing, supply chain, retail and transportation solutions to JDA’s 5,800 customers and rich suite of solutions will result in the most comprehensive end-to-end supply chain management offering in the market worldwide. This will provide significant opportunity for greater value to our combined customer base and to prospective customers in the market.

• Upon the close of the transaction, which is currently scheduled for the first quarter 2010, JDA will have total revenues of more than $600 million with approximately 3,000 associates worldwide. The size and scope of the combined organization will provide new and increased opportunities for associates to develop their skills and advance their career aspirations with the company. JDA is very pleased to be adding the rich heritage of innovation that i2 and its associates bring to the company. The combined talents of all associates will continue to add to the rich history of innovation for both companies.

During the upcoming weeks, a significant degree of integration planning will take place. The primary goal of this planning process is to create one seamless organization capable of delivering our compelling value proposition to our customers as rapidly as possible. We will take advantage of the hard work and analysis that was done by both JDA and i2 associates a year ago to identify the best practices of both companies. This will allow us to move more quickly with respect to decisions needed to create a high-performing organization from day one.

Clear, consistent communication is critical to our success. We are committed to keeping you informed, and will establish a transition page on jNET in order to provide you with up-to-date information related to the acquisition and integration process. We will also provide a vehicle for you to submit questions related to the process. An all-hands meeting will be scheduled for tomorrow and we will share the full integration plan with you in the near future. I appreciate the dedication and hard work that JDA associates have demonstrated over the years in helping to grow the company and positioning us to take this next step in executing on our growth strategy. I look forward to your support and continued hard work as we move forward in completing this process and begin to integrate i2 into JDA, creating a high performing and successful organization that will provide value and opportunity for customers, shareholders and associates.

JDA CEO
