Segue Software Responds to Recent Internet Trading Problems with First Internet Trading Scenarios.

LEXINGTON, Mass.--(BUSINESS WIRE)--Feb. 11, 1999--

E-Business Management Company to Demonstrate Ability to Model

On-Line Trading Scenarios for Successful

Continuous Deployment at Worldwide Seminar Series

Segue Software, the e-Business Management Company(TM), today announced the development of on-line trading scenarios, utilizing SilkRealizer, a component of Segue's LiveQuality EBMS, in response to the recent rash of on-line trading service failures. The On-Line Trading Model (OLTM) scenarios will be demonstrated during a series of free worldwide seminars beginning March 2 in New York.

"Recently, the Securities and Exchange Commission stated that on-line trading accounts for approximately 25 percent of all retail stock trades, with the number of online brokerage accounts expected to exceed 10 million by the end of the year," said Steve Butler, Segue's President and CEO. "This increasing volume of on-line trading, coupled with rapid changes and constant updates to associated brokerage's Web sites spurred on by competitive pressures are exposing the challenges of keeping these sites running. The success of individual on-line brokers will be tied directly to their ability to manage these challenges. Simply letting the customer debug their sites will not be tolerated."

The challenge these brokerage firms face, as do all corporations deploying mission- critical e-business applications, is the ability to manage the chaotic nature of continuously deployed, universally accessed, functionally unbounded e-commerce systems. Recently, Segue Software announced the industry's first E-Business Management System (EBMS), LiveQuality 2.0, to address the radically new development and deployment process employed by leading e-business customers, including the burgeoning on-line trading market.

"Segue's extensive experience helping on-line brokers deliver reliable sites has taught us that traditional load testing of their back office systems is woefully inadequate," stated Michael Maggio, Segue's senior vice president and general manager. "With customers such as Ameritrade, Fidelity, Charles Schwab and T. Rowe Price, we experienced first hand the demands rapid content change, diverse server protocols, large and unpredictable volume, and diverse security requirements have on e-business reliability. We found our customers needed to go beyond traditional legacy component level testing for regression and performance of individual aspects of on-line trading systems. Thus a key product in our LiveQuality EBMS, SilkRealizer, provides the ability to do that by modeling real-world scenarios that occur in today's mission critical e-business applications."

The recent challenges on-line trading firms have met ranged from new software installations to application and Web server scalability. The underlying challenge behind all the problems is tied to an organization's inability to manage the rapid development and deployment process unique to e-business applications. This process is managed through LiveQuality EBMS. The value of LiveQuality EBMS is four-fold. First, it delivers the fastest deployment time for e-business systems, a requirement in today's competitive on-line market. Second, it maximizes performance for all users, providing a critical customer-loyalty factor. Third, it minimizes or eliminates e-business downtime, which hits the bottom line immediately. Finally, it maximizes e-business results to the corporation, preserving and increasing the investment in today's leading initiative for Fortune 1000 companies.

To demonstrate the new On-Line Trading Model scenarios, Segue will deliver a free, worldwide seminar series. Focused on helping corporations identify the challenges of e-business deployment, Segue will utilize an on-line trading system called E*Street to demonstrate the power of LiveQuality EBMS. The series, "Successful E-Business Deployment," runs throughout March and April in numerous cities including Atlanta, Austin, Boston, Chicago, Dallas, Denver, Frankfort, Los Angeles, London, Munich, New York, San Francisco, San Jose, Toronto and Washington, D.C. Attendees will receive a free copy of SilkPerformer Web Benchmark and SilkControl Individual Content Management to experience the key features of LiveQuality. Details on the seminar series as well as additional locations can be found at www.segue.com.

"As this burgeoning e-business market continues, the successful survivors will be those companies that can avoid the unfortunate headlines in today's news," continued Maggio. "Segue has invested heavily to manage these challenges. Our breakthrough technologies, multi-year product development, deep corporate investments and our partnerships with leading Internet infrastructure companies, such as Netscape Communications and IONA Technologies, will help us deliver world class solutions to our growing installed base of over 900 e-business customers."
