LINMOR's NEBULA to Integrate with Micromuse's NETCOOL(R)Suite, Combining Fault and Performance Management for Service Providers

Micromuse Inc. (Nasdaq: MUSE), the leading provider of fault and service-level management software, and LINMOR Technologies (CDNX:LIR), the leading provider of realtime performance management software, today announced that LINMOR has joined the Micromuse Developers Alliance(TM).

As a Micromuse Netcool Ready(TM) Partner, LINMOR will license the Netcool Software Development Kit(TM) to develop a network interface with Netcool applications and create a Netcool Ready(TM) solution for LINMOR's NEBULA(TM) Performance Monitor (PM). The Micromuse Developers Alliance is a program for leading independent technology providers seeking to develop and offer integrated, off-the-shelf, multi-vendor, open OSS management solutions to service providers and corporate customers.

"Maintaining fast, reliable delivery of mission critical information is the key to success in the carrier industry. Integrating the Netcool fault management applications with LINMOR's NEBULA PM will enable network service providers to offer premier quality data services to their customers," said John Farrell, President, Chairman and CEO of LINMOR. "The combination of Micromuse's Netcool suite with NEBULA PM and our commitment to the Micromuse Developers Alliance Program, will provide our customers with a complete network performance management solution."

The integration of NEBULA PM with Netcool will enable data collected by NEBULA PM to be displayed in the Netcool EventList(TM) console. This will allow network operations administrators to provide enhanced solutions for efficient network fault analysis and network resource availability to help predict and prevent network slow downs and interruptions in network-based customer services. The applications provided by NEBULA PM and the Netcool suite provide service providers with the tools they need to deliver enhanced service assurance and full network integrity to their customers.

"We are delighted that LINMOR has joined the Micromuse Developers Alliance," said Tim Tokarsky, Micromuse's Senior Vice President, Business Development. "The goal of the program is to provide off-the-shelf, integrated solutions for our mutual customers. Integrating Netcool software and NEBULA Performance Monitor means that network service providers will have a completely integrated fault and performance management system for their complex network infrastructure, allowing them to provide an even higher level of quality of service to their customers."

The Micromuse Developers Alliance provides Micromuse and its alliance partners with the resources to cooperatively pursue business, technical and marketing opportunities. Already a significant number of vendors have expressed interest in Micromuse's Developers Alliance to develop and provide off-the-shelf, integrated solutions for mutual customers. Toward that end, Micromuse actively enlists best-in-class solutions providers offering complementary applications. Micromuse furnishes its approved Netcool Ready Partners with the Netcool Software Developers Kit(TM) (SDK). Provided in CD-ROM format, the Netcool SDK provides all the tools necessary to develop Netcool Probes, Gateways and Data Source Adapters.

About the Netcool Suite

Micromuse's Netcool software suite collects management data from more than 200 management environments and network devices, including voice, data and Internet. Fault data is rapidly processed and filtered by the Netcool ObjectServer(TM), an in-memory database. The Netcool application allows operators to build views of service availability in realtime, helping them manage networks more efficiently. Because it is scalable and deploys rapidly, the Netcool business model allows service providers to expand their networks as their markets grow.
