Advanced Utility Systems Announces Agreement with SemStream Arizona

May 15, 2007 - Tulsa, Okla. and Toronto Canada

Advanced Utility Systems Corporation (Advanced), a wholly owned subsidiary of Harris Computer Systems (Harris), is pleased to announce that SemStream Arizona Propane, L.L.C. (SemStream Arizona) has selected CIS Infinity as its customer information system and utility billing solution.

SemStream Arizona’s agreement builds on one previously in use by its predecessor, Energy West Propane. SemStream Arizona recently became operator of the retail propane business through an acquisition.

“Advanced is extremely pleased with SemStream Arizona’s commitment to maintain its use of CIS Infinity,” comments Steve Hammond, Harris Vice President for the Advanced Business Unit. “And, SemStream Arizona’s recent decision to convert a pending acquisition of another propane operation, also located in Arizona, to CIS Infinity is a true testament to the strength of our solution.”

SemStream Arizona’s solution, hosted in its data center in Tulsa, Oklahoma, will utilize CIS Infinity’s existing billing and asset management functionality tailored for the propane and natural gas retail market. SemStream Arizona also will implement eCare, Advanced’s web-based electronic bill payment solution, to allow its customers to benefit from the real-time access to customer-specific information.
