ISTA EXPANDS CONTRACT WITH ARADYME AS RESULT OF PROJECT SUCCESSES OREM, Utah - September 27, 2005 - Aradyme Corporation (OTCBB: ADYE), a data management company, today announced that ista, the worldwide market leader for submetering and billing of water and energy consumption, has expanded its scope of work with Aradyme, which has subsequently resulted in a substantial increase in the total contract value. The additional work was awarded to Aradyme after Aradyme successfully met its September 1, 2005 deadline for cleansing and integrating meter and premise data for 500,000 accounts on an AS400 system with 200,000 accounts on a SQL Server system following ista's acquisition of USI Energy. As part of the expanded scope of work, Aradyme will provide ista with a solution that will enable it to automate the upload, conversion processing, and download of customer account data on a daily basis. The Aradyme solution will also help mitigate the risk of any of the data integrity being compromised as the data is transformed into the new system. The additional work is slated to be completed by mid-October 2005. "Aradyme's technology and timely delivery has been invaluable in integrating our systems and streamlining our billing efforts," said Michael Stowers, vice president of IT, ista North America. "We have been so impressed with both the quality of Aradyme's work and their technology that we look forward to deriving even more value with the additional Aradyme solution. This new solution will enable us to identify and resolve exceptions in new customer account data on a daily basis that would otherwise take us weeks to uncover, and will also help simplify the process of keeping our systems up-to-date." "We are excited about the success that Aradyme and ista have been able to achieve on this project and look forward to providing ista with an additional solution," said James R. Spencer, chief executive officer of Aradyme.
