COLUMBUS, Ind.--(BUSINESS WIRE)--May 8, 2003

Cummins Inc. (NYSE:CUM) announced today that it has presented the prestigious Perr Award for 2002 to Jeffery L. Campbell, Lester L. Peters, Gary L. Gant, David P. Genter and Kevin R. Wadell.

The winners were recognized for their invention of a design improvement on fuel injectors, which has dramatically improved the performance of Cummins engines. It has also increased the service intervals on Cummins injectors, leading to lower maintenance costs for Cummins customers.

Cummins presents the Dr. Julius P. Perr Innovation Award each year to recognize innovative contributions of Cummins personnel. The award is named for Dr. Julius P. Perr, a key inventor named on more than 65 U.S. Patents. Throughout Dr. Perr's 40-year career at Cummins, his innovative designs enabled the Company to take a leadership role in the diesel engine manufacturing industry.

To be eligible for the Perr Award, an invention must be patented and have demonstrated significant benefit to the business of the Company. The Invention Review Committee (IRC) for each Cummins business organization screens eligible inventions and selects candidate technologies for presentation to the Perr Award Board of Trustees. The Board of Trustees, which is comprised of industry experts from each of the technical disciplines and business units, then selects the winners and runners-up. For the 2002 award, corporate wide, 181 eligible inventions were screened by the IRC.

Also recognized as "first runners-up" for the 2002 Perr Award are Mark R. Stepper, Gregory R. White and Ronald B. Lannan for their invention of a method and apparatus for generating calibration information for an electronic engine control module. With the advent of electronic control modules (ECMs), there was a need at Cummins to reprogram the ECM memory for different power ratings and features, without physically replacing or modifying the module. A process was invented to generate, distribute, manage and support the multiple calibrations, engine ratings and features.
