Business Editors/High-Tech Writers

SAN DIEGO--(BUSINESS WIRE)--Jan. 3, 2001

Altris Software, Inc. (OTCBB:ALTS), a leading Document Service Provider (DSP), today announced that AmerenUE's Callaway Plant, based in Callaway County, Mo., has selected Altris' eB(R) document management solution for its Records Control department to manage records and procedures relating to power production at the plant.

AmerenUE's current Altris system will be upgraded to the eB Doc Controller system to deliver procedure records to users with the assurance that the user is accessing the most current document relevant to a specific procedure. Adding eB Doc Controller as part of the upgrade could eventually replace up to 15 existing mainframe applications. The implementation of eB Workflow will allow the Plant to automate many of the manual routing and approval processes currently in place.

"We chose to remain with Altris because eB Doc Controller provides the functionality we require," said Gary Czeschin, superintendent, AmerenUE Callaway Plant. "In the highly regulated environment of nuclear power, the integrity of our information is essential. At the same time, we have many opportunities to streamline our information management process. We are looking forward to gaining both of these benefits from our eB implementation."

Roger Erickson, CEO of Altris Software Inc, commented, "We are delighted that AmerenUE has selected eB Doc Controller. The rich capabilities it offers in managing documentation and relating this to physical assets and business processes will enable the plant to increase efficiency in the execution of its every day business operations. In addition, the system's ability to offer a secure environment will give AmerenUE the confidence that its control procedures are being tightly managed."

AmerenUE

AmerenUE's nine power plants not only produce enough electricity to meet the needs of the operating company's existing customers, but they also provide additional power for sale outside the system. The Callaway nuclear plant, which produces about a quarter of AmerenUE's power, has consistently been an industry leader in both safety and performance. Since startup in 1984, Callaway has generated an average of 8.9 billion kilowatthours of electricity per year -- equal to the amount used annually by more than 750,000 average households. Through the end of 1999, Callaway ranked 7th in the U.S. in lifetime electricity generation. All the plants with more lifetime generation had been operating at least 11 years longer than Callaway.
