1 EXHIBIT 99.1 BMC SOFTWARE TO ACQUIRE BGS SYSTEMS STRATEGIC ACQUISITION WOULD COMBINE LEADING TECHNOLOGIES TO PROVIDE APPLICATION SERVICE ASSURANCE PRODUCTS HOUSTON -- (Feb.2, 1998) -- BMC Software, Inc. (NASD: BMCS), a leading developer and vendor of computer software solutions that improve the availability, performance and recoverability of business-critical applications and data, today announced the execution of a definitive merger agreement with BGS Systems, Inc. (NASD: BGSS) of Waltham, MA. This strategic acquisition combines BGS's industry-leading BEST/1(R) performance analysis and prediction technology and products with BMC Software's suite of PATROL(R) application management, data management and performance optimization solutions, providing the industry's first application service assurance products. BMC Software will pay the equivalent of $45 in BMC Software common stock for each share of BGS common stock, using the average price per share of BMC Software common stock during a ten day trading period preceding closing. Total value of the transaction is approximately $285 million. The transaction is to be accounted for as a pooling of interests and is to be treated as a tax-free reorganization for federal income tax purposes. The transaction is expected to close within 60 to 90 days, subject to BGS shareholder approval, regulatory approval and other customary closing conditions. "BGS has the best analytical and predictive tools for enterprise information systems," said Max Watson, chairman, president and chief executive officer of BMC Software. "They have delivered solid products for over twenty years, know their market segment cold and have great people. We see a clear customer requirement for correlating and interpreting the tremendous amount of performance statistics and data that PATROL provides. BMC has a road-map for providing these additional capabilities, and the BGS BEST/1 products fit perfectly with our plans. We are very enthusiastic about the potential to leverage PATROL's market momentum and product breadth with BGS's products, people and capabilities." Watson added that the similarities between BMC Software and BGS Systems should simplify the integration of the companies and their technologies. Both companies' have extensive expertise in developing high value solutions for mainframe and open systems environments and share a direct sales distribution model targeted at large enterprise systems. MERGER STRENGTHENS PATROL'S LEADERSHIP AND EXPANDS ENTERPRISE PRODUCT LINES BMC Software currently leads the market for monitoring and event management software with its PATROL Management Suite, which provides the broadest platform coverage with support for all of the leading operating systems, database management systems and enterprise resource planning applications. PATROL collects and delivers more performance metrics than any comparable systems management tool and offers an unrivaled ability to collect and display 2 performance data from large and complex distributed information systems. With this merger, BMC Software will acquire BGS's industry leading BEST/1 performance analysis and prediction products and integrate them with PATROL. The combination of BEST/1's superior performance analysis and prediction capabilities with PATROL should enable BMC Software to deliver pro-active application service assurance products that have the predictive capability to anticipate system events, such as an outage or throughput bottleneck, and take corrective action well before the problem occurs. This capability would enable internal information systems organizations to provide application service assurance to their customers and reduce the administrative costs and complexity associated with today's heterogeneous and distributed information systems. In addition to its performance management solutions for UNIX and Microsoft NT-based distributed systems, BGS provides a full line of performance management products for mainframe systems. BMC Software believes its strong presence and reputation as a mainframe systems management vendor should provide for expanded growth opportunities for the BGS mainframe product line. A 1997 industry analyst report by International Data Corporation (IDC) defines performance management as including performance monitoring, simulation, management and resource tracking for mainframe and open systems.--1 The IDC study identifies performance management as the largest systems management market segment at approximately $1.8 billion. The acquisition of the BGS Systems BEST/1 products will position BMC Software solutions even stronger in this market. BGS Systems President and Chairman of the Board Dr. Harold S. Schwenk, Jr. added, "BGS is the leader in assuring high levels of application performance across the enterprise and we are __________________________________ 1--Copyright 1997 IDC.
