PlantCML Announces Intent to Acquire Dialogic Communications Corp.

North America’s top provider of emergency response solutions acquires leading emergency notification capabilities.

Temecula, CA/Franklin, TN (September 12, 2006 ) – PlantCML, North America’s leader in mission-critical communications systems for emergency contact centers announced today the signing of a definitive agreement to acquire Dialogic Communications Corporation, the largest provider of emergency notification technology. The planned acquisition adds another high-demand element to PlantCML’s portfolio of communications products, further solidifying its position as the country’s leading vendor of emergency response management solutions. The transaction will be funded by Golden Gate Capital, a San Francisco-based private equity firm with $2.8 billion of capital under management. PlantCML is a portfolio company of Golden Gate Capital.

The acquisition will open mature channels of distribution for Dialogic’s notification solutions, while providing a platform for PlantCML to offer additional on-premise or hosted services to its existing clients. It also provides PlantCML a strong entry point into the commercial private safety market given Dialogic’s admirable list of corporate business continuity customers. Additionally, each company holds a strong, complementary presence that can be further leveraged in the Federal market space. Dialogic will keep its corporate name, becoming a wholly owned subsidiary of PlantCML. The transaction is scheduled to close within thirty days. Financial terms of the deal were not disclosed.

“We are excited to continue to support PlantCML as it further consolidates the emergency response solutions space,” said David Dominik, Managing Director at Golden Gate Capital. “With the acquisition of Dialogic, PlantCML will add another mission-critical element to its core suite of products, enhancing PlantCML’s leadership position in its industry.”

Timothy Fuller, President and Chief Executive Officer of PlantCML, states, “This acquisition is consistent with our long-term strategy of offering customers a comprehensive suite of critical communications products. Notification and response technologies are fast becoming a necessity for communities and organizations across the globe. With the combined resources of PlantCML and Dialogic, no company is better positioned to deliver these crucial solutions.”

“Our focus is on customer needs,” said Gene Kirby, President and CEO of Dialogic. “With this acquisition, organizations that need to communicate quickly, easily and accurately in times of crisis will have access to more options at a greater overall value. We are proud to become a part of the PlantCML team.”

Existing agreements between each company, its customers, partners and service providers will be honored. “It’s very much business as usual for customers, partners and others who have dealings with PlantCML and Dialogic,” said Mr. Fuller.
