April 12th, 2005 – Rockville, MD – Jinfonet Software (www.jinfonet.com), a leading provider of 100% J2EE embedded reporting solutions, announced today that Cubist Pharmaceuticals (NASDAQ: CBST), makers of the antibiotic Cubicin, has embedded JReport into their sales force automation tool to add reporting functionality. The web and mobile enabled application supports Cubist’s sales team by managing key information, including account details, account planning, contact management, Cubicin sales data, and upcoming events. It also houses an extensive document library and drug collateral order requests. JReport’s reporting capabilities help Cubist’s account managers to better monitor and report on all of these critical data categories, and lets them create sophisticated, customizable reports that explore relationships between data points so they can better address the needs of their customers.

“We have been pleased with the capabilities achieved by our implementation of JReport,” said Anthony Murabito, Cubist’s Vice President of Information Technology. “JReport was quick and easy to install, and integrated seamlessly with our sales data mart. JReport’s powerful reporting capabilities provide our field force with the ability to produce instant reports to manage both user and account level business activities. Because JReport’s ad hoc reporting capability is so intuitive, our entire field force was able to use it to extract data with minimal training or IT support.”

JReport was the only reporting tool that was flexible enough to seamlessly integrate with the application and support its unique deployment model, which allows online and offline usage. In online usage mode, the user is connected to the application server and can run the application through Internet Explorer on any machine. In this mode, the user can browse a catalog that features a wide variety of report templates and select the one that best fits their current reporting needs. Reports created from templates are deployed via the application interface in DHTML and are fully actionable; end users can easily sort, filter and drill through reports in real-time to meet the specific data presentation requirements. Reports can be exported to a wide variety of standard formats, like email, Excel, and PDF, and distributed to colleagues, partners, and customers.

When a user is offline, JReport functionality is almost identical to online usage. Users can create static reports on sales data from any of the JReport templates that were pre-loaded on their remote computer. Once the computer is connected to the Cubist network, generated reports sync with the JReport server and immediately become actionable. At that time, users can access the full range of JReport interactive capabilities.

“JReport was a logical choice for Cubist’s sales force automation system, because its flexible design made it the only solution that was able to seamlessly embed in the application and provide the sophisticated on-line and off-line reporting capabilities that the Cubist sales force required,” said John E. Gularson, Jinfonet’s Executive Vice President. This partnership is indicative of Jinfonet’s commitment to providing ‘right-sized’ embedded reporting solutions. We are entirely focused on providing Cubist, and all of our other 800+ customers, with a scalable, customizable solution that offers any reporting functionality they will ever need, along with the freedom to embed only the functionality they currently require.”

The JReport-powered version of Cubist’s sales force automation tool has been recognized worldwide as one of the most successful applications of its kind. In Q4 2004, The Mobile Enterprise Alliance (MEA), a global advocacy group promoting the business benefits of workforce mobility to enterprise end users and decision makers, named the tool as a finalist for the MEA Mobile Impact™ Award.
