RAZOR SOFTWARE CM SYSTEM PROVIDES SUPPORT FOR MICROSOFT .NET AND IS ACCEPTED INTO IBM TOOLS NETWORK PRODUCTS

With the integration of Razor into Microsoft .NET and acceptance into IBM Tools Network Products, Razor can now deliver powerful SCM functionality to Microsoft and IBM customers.

ONEIDA, NY - March 12, 2003 -- A newly released version of Visible Systems' Software Configuration Management product allows software developers and configuration managers to use Razor's powerful features within their respective Microsoft .NET IDE and IBM eServer platforms, products and tools.

"This release greatly enhances Razor's value to Microsoft and IBM customers who require a more superior level of Software Configuration Management (SCM) across their respective development environments and product tools", said Mike Cesino, President and COO of Visible. "For Microsoft developers, Visible has made it easier to continue to work within the Integrated Development Environment (IDE) of their choosing while placing their .NET project activities directly under configuration control in Razor", added Cesino.

Razor 4.3C also marks the beginning of Razor's support for applications running on IBM eServer platforms. The new IBM eServer platforms http://www-1.ibm.com/servers/enable/tools/ are a line of highly integrated, reliable servers that deliver an on demand multi-operating environment for WebSphere, Linux, Windows, OS/400 and other e-business solutions. With new flexible packaging options, as well as enhanced scalability and manageability capabilities, customers can grow and adjust dynamically to the changing requirements of e-business. Now that Razor meets the acceptance criteria, IBM eServer platforms are able to run Razor as their preferred SCM application.

"We are pleased to inform Visible Systems about Razor's acceptance into IBM's Tools Network. We look forward to our working relationship to help make our solutions the best in the industry", added Elaine Case, Director of IBM Solutions Marketing Program.
