IRVINE, CA, Dec 28, 2010 — Epicor Software Corporation (NASDAQ: EPIC), a leading provider of enterprise business software solutions to the midmarket and Global 1000 companies, today announced that it has completed its previously announced acquisition of SPECTRUM Human Resource Systems Corporation.

“Epicor is now poised to bring the power of a truly integrated next-generation enterprise resource planning (ERP) and HCM solution to market,” said George Klaus, chairman, president and CEO of Epicor. “Our strategy to provide focused market-leading technology that aligns to industry best practices is further enhanced with the addition of integrated HCM solutions. We are pleased to have closed this acquisition slightly ahead of schedule and have begun the process of integrating Spectrum and its technology into Epicor.

“The fact that we have just closed our first Epicor ERP deal with a Spectrum customer this quarter is further validation that the combined company will deliver even greater value to all of our combined customers,” said Klaus.

Virtual Radiologic Corporation (vRad) is a technology-enabled national radiology practice working in partnership with local radiologists and hospitals to optimize radiology’s pivotal role in patient care. Currently implementing Spectrum’s HCM solution, vRad just selected Epicor’s next-generation ERP for its superior technology and functionality to automate business processes and support company growth plans. “We were pleased when we heard Epicor had acquired Spectrum — having a single provider to tend to our overall financial and human resources enterprise information systems needs was definitely a plus in our decision to go with Epicor,” said Rick Jennings, chief technology officer of Virtual Radiologic Corporation.

As noted in the news release, “Epicor to Acquire Spectrum Human Resource Systems Corporation,” issued on December 13, 2010, Spectrum’s best-in-class Web-based human resource and talent management solutions are the core of the newly formed Epicor Human Capital Management (HCM) group. The acquisition broadens Epicor’s position as a leading provider of complete end-to-end enterprise business solutions to the manufacturing, distribution, retail, hospitality and services sector, with the addition of end-to-end HRMS. Leveraging combined focus on Microsoft .NET, Web 2.0 and cloud computing technologies, and expertise in delivering world-class business solutions, Epicor will deliver a solution that requires no compromises and what no other company is providing today — an end-to-end HCM solution backed by local country support, localization and language, and supporting flexible delivery options including software as a service (SaaS), hosted, and on-premise.
