SUNNYVALE, Calif., July 23, 2001 — Resonate Inc. (NASDAQ: RSNT), the leading provider of active service level management solutions for e-business applications, today announced that Eastman Chemical Company (NYSE: EMN), a leading international chemical company which produces chemicals, fibers and plastics, has selected Resonate Commander Solutions™ to ensure its e-business transactions. Eastman is the world's largest supplier of polyester plastics for packaging; a leading supplier of coatings raw materials, specialty chemicals and plastics; and a major supplier of fibers and basic chemicals.

"As the first chemical company to offer its customers a new way to do business through online transactions, it was important to us to select a cutting-edge solution capable of supporting our e-business, " said Charles Oliver, director of Global Computing and Telecommunication Services at Eastman. "Resonate provided us an immediate service level management solution that not only monitored our e-business services, but could take action to correct potential problems. The availability and performance of our e-business is crucial in protecting an important revenue stream for our company."

Unlike traditional service level management solutions, Resonate Commander Solutions are focused on e-business services and can take action to manage the user experience during problem resolution. Eastman's customers are able to place and check the status of their orders online 24 hours a day, 7 days a week. With Resonate Commander Solutions, these e-business services can be monitored and managed to ensure the service levels of each transaction, eliminating hard failures and degradation in user experience.

Eastman will be able to monitor and manage the various elements of its e-business infrastructure, from the user to the tiers inside the firewall and from single sites to multiple geographic locations using Resonate's solutions. Resonate provides these capabilities through an end-to-end services model, allowing Eastman to view and control the performance of its e-business as a service rather than solely as individual components within the infrastructure.

"We are excited to partner with Eastman to support them in driving and growing their commitment to e-business ventures in their industry including Eastman.com, customer center services and online auctions, " said David Guercio, vice president of Americas, Sales and Services at Resonate.
