FAIRFAX, Va.--(BUSINESS WIRE)--June 19, 2003--ExxonMobil Research and Engineering Company (EMRE) announced today that Fabryka Parafn Naftowax Sp. Z.o.o., and Refineria Trzebinia have selected EMRE's Wax HYDROFINING(1) technology for the production of higher-valued wax to be applied at Refineria Trzebinia.

ExxonMobil's Wax HYDROFINING process is the final critical step for processing low-oil-content waxes from dewaxing/deoiling to produce wax with low sulfur, improved color and stability that meets purity specifications by ultra-violet absorption testing. This technology is applicable to either crystalline wax from lube distillates or microcrystalline wax from deasphalted oils. The technology enables refiners to upgrade their wax to high-valued wax used for consumer products such as: candles, wax paper, fruit coatings, paper cups, as a seal for medicines, and for similar applications where high purity is required.

There are over a dozen worldwide applications of EMRE's Wax HYDROFINING technology, including four ExxonMobil units. ExxonMobil has continued to apply its knowledge and operating experience from these commercial units to improve the current Wax HYDROFINING process configuration and design.

EMRE is the research and engineering arm of ExxonMobil (NYSE:XOM), a leading global oil, natural gas, and petrochemicals company whose subsidiaries have operations in nearly 200 countries and territories.
