JDA Wins 2005 Best Third Party Provider Award from VICS Association; Win Marks Fifth Consecutive Year JDA or Its Customers Outdistance Competition with VICS Collaborative Commerce Achievement Award.

SCOTTSDALE, Ariz. -- JDA(R) Software Group Inc. (Nasdaq:JDAS) announced that it won the 2005 Voluntary Inter-industry Commerce Standards (VICS) Award for Best Third Party Provider. The VICS association honored JDA for its JDA Portfolio(R) Collaborative Planning, Forecasting and Replenishment (CPFR) solution that enables retailer-manufacturer partners to synchronize supply chain processes for improved service levels on reduced inventory, increased sales and more efficient logistics order flow. This year's win over finalists Oracle/Retek and Symbol Technologies marks the fifth consecutive year that JDA or its customers have been selected as outstanding examples of strategic thinking and supply chain leadership by the VICS Association.

Longtime Consumer Goods Customer Nominates JDA

JDA was nominated for the VICS' Best Third Party Provider award by a leading consumer goods manufacturer that has launched three CPFR initiatives with Portfolio Collaborative Solutions(TM) from 2002 through 2004. This longtime JDA customer has achieved stellar results, including reducing out of stocks by 16.6 percent in 2004 over 2003. Fred Baumann, JDA's vice president of collaborative solutions, accepted the award on May 24, 2005, during a ceremony held in conjunction with the VICS/Retail Systems Super Conference in Chicago.

"This prestigious industry recognition speaks strongly to the value that we deliver to our demand chain customers. We are proud to have helped more top companies establish exceedingly successful CPFR programs than any public retail exchange. Our customers have achieved unprecedented

ROI because they measure and guide their programs with key metrics, develop patterns of trust and communication, embrace a willingness to change and rely on our award-winning software to enable their strategy," said Baumann.

"We believe this unbeatable combination is why year after year the VICS Association recognizes our customers', and now our company's, dedication to more effective supply chain partnerships," added Baumann.

Rite Aid among JDA's CPFR Customers Achieving ROI

According to Baumann, approximately 260 trading partner pairs have utilized JDA solutions to support more than $4.3 billion in trade volume. Among JDA's customers is Rite Aid Corp., a leading drugstore chain with annual revenues of $16.8 billion. Rite Aid and a trading partner won the 2002 VICS Collaborative Commerce Achievement Award for "Best in VICS CPFR(R) Implementation" and were named a finalist for that award in 2005.

"We are proud of the results that we have achieved with our CPFR program," said Paul Hanko, vice president of supply chain for Rite Aid. "By capitalizing on our supplier partner's unique product and logistics insight, along with the collaborative framework that JDA's replenishment and CPFR solutions support, we have achieved improved warehouse service levels to stores, reduced out of stocks and realized other supply chain efficiencies. Our partnership with JDA began in 1992 and we continue to see improvements in inventory management and supplier relationships."
