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. "With this
project, not only have we been able to continue to demonstrate the value of our
technology and processes, but also showcase some of the many ways in which our
solutions can be used by business owners to more cost effectively and
efficiently run their business."
