DALLAS--(BUSINESS WIRE)--Sept. 12, 2002

Probex Corp. (AMEX:PRB), a technology based renewable resource company, today said that Ohio Governor Bob Taft has announced that Columbiana County will receive a $300,000 grant to assist Probex with work at its planned Wellsville reprocessing facility.

The grant will be awarded through the Ohio Small Cities Community Development Block Grant (CDBG) Economic Development Program administered by the Ohio Department of Development.

Probex Chairman, President and CEO, Charles M. Rampacek, noted that: "The CDBG funds will be used to assist in the realignment of a railroad track in the area that will be used to transport material to and from the site." He added that: "We are delighted to be a part of this program which will benefit the economic development of the community and look forward to beginning construction of our reprocessing facility at Wellsville as soon as we complete our ongoing project financing process."

The CDBG Economic Development Program provides grants for economic development projects that create and/or retain permanent, private-sector job opportunities. The grants provide financial assistance through local governments to private entities for economic development projects, and for public improvements directly related to business development. Jobs created through the program must benefit primarily low and moderate income Ohioans.
