i2 Board of Directors Names Michael E. McGrath Chief Executive Officer and President

Sanjiv Sidhu resigns CEO and president positions; remains chairman of the Board

DALLAS — February 28, 2005 — i2 Technologies, Inc. (OTC: ITWH), a leading provider of demand-driven supply chain solutions designed to enable business agility, today announced that its Board of Directors has named Michael E. McGrath chief executive officer and president. McGrath replaces Sanjiv Sidhu, who remains chairman of the Board.

In July 2004 the company announced that Sidhu had intended to step down and that it would begin to search for a successor CEO.

“Michael McGrath brings tremendous knowledge and a wealth of experience to this position,” said Sidhu, who founded i2 in 1988. “He has exhibited strong leadership as a member of our Board of Directors, and we are extremely pleased that he has chosen to take a larger leadership position with i2,” said Sidhu. “I remain committed to i2, and intend to continue working with employees and customers to help take i2 to the next level.”

According to Sidhu, the Board of Directors has given McGrath a clear mandate. “We expect Michael to refocus and resize i2, while at the same time establishing a strong foundation for future growth. It is then expected that we will recruit a new CEO, and that Michael will continue his leadership by assuming my role as Chairman of the Board.”

“I have admired Sanjiv’s vision and leadership in the supply chain industry for many years. The positive impact i2’s people and solutions have had on many of the world’s leading companies is impressive,” said McGrath. “I am excited about this opportunity to lead i2. I look forward to extending i2’s tradition of delivering value to customers, and quickly returning the company to operating profitability.”

A renowned expert on supply chain management, product development, and product strategy, McGrath joined the i2 Board of Directors in August 2004. He is co-founder of Pittiglio Rabin Todd & McGrath (PRTM), a leading management consulting firm to technology-based companies. He retired as chairman and CEO of PRTM’s Atlantic Region in July 2004 after spending 28 years building the company into a highly successful management consulting firm.

While at PRTM, he initiated the company’s product development consulting practice, establishing it as one of the most successful and effective models of the product development process for technology-based industries. In 1993, McGrath created the Supply-Chain Operations Reference-model^® (SCOR^®) to define a standard for the supply chain management process, which is now managed as an industry standard by the Supply-Chain Council.

McGrath also founded IDe, a leading provider of integrated solutions for Development Chain Management in June 1998, and has served as IDe chairman since October of that year. He is also the author or co-author of five books and numerous articles. Over the last decade, his book, “Product Strategy for High-Technology Companies: How to Achieve Growth, Competitive Advantage and Increased Profits,” has been used by many companies to guide strategic growth.

Prior to co-founding PRTM in 1976, McGrath worked for Price Waterhouse & Co., Texas Instruments and McCormack & Dodge, where he contributed to the pioneering efforts to create the packaged applications software industry in 1971. He holds a bachelor’s degree in Computer Science and Management Science from Boston College and a master’s in business administration from Harvard Business School. He is also a certified public accountant.
