EPIC Epicor Software Corp. (MM)

Epicor Software Corporation (NASDAQ: EPIC), a leading provider of enterprise business software solutions for the midmarket and divisions of Global 1000 companies, today announced RT Logic (www.rtlogic.com), a wholly-owned subsidiary of Integral Systems, Inc. (NASDAQ: ISYS), has selected Epicor's next-generation enterprise resource planning (ERP) solution Epicor 9 to support future growth.

RT Logic designs, develops, and delivers innovative signal processing systems for the space and military communications industry. The company's product lines are used for satellite test, launch vehicle telemetry, on-orbit satellite control, Satellite Communications (SATCOM), missile and airborne communications, as well as spectrum monitoring/interference detection and geo-location.

Founded 12 years ago, RT Logic's commitment to customer satisfaction and innovation has resulted in consistent business growth. With annual revenues now in excess of $50M, over 150 employees, and with more growth on the horizon, RT Logic kicked off an initiative to build a new level of scalability into its infrastructure. "Our company was at an inflection point and an infrastructure investment was necessary to allow the business to scale to meet future business growth objectives," said Kirk Smith, Production Director for RT Logic. "We wanted an ERP solution that was intuitive and easy to navigate, and that was flexible enough to support our unique business processes."

RT Logic found the right solution for their business in Epicor for Aerospace & Defense. With Epicor, RT Logic expects to gain efficiencies and improve the scalability of business operations as workflows are automated, data entry duplication is eliminated, and access to a single instance of real-time information is made available throughout the organization.

RT Logic worked with a regional Epicor value-added reseller (VAR), The Estes Group, to select Epicor for Aerospace & Defense. The Estes Group provides software sales and professional services to a variety of companies in the US including the manufacturing, distribution, health care, financial services, senior living and retail sectors, and will be working with RT Logic to implement Epicor.

"We are delighted that RT Logic chose Epicor over strong competition," said James Norwood, senior vice president, product marketing for Epicor. "Epicor offers RT Logic an intuitive and flexible technology foundation tuned to the specific needs of their industry that will scale with company growth, and provide a low total cost of ownership."
