Citrix Completes Acquisition of Net6; Extends Leadership Role in Access Infrastructure Market.

FORT LAUDERDALE, Fla. -- Acquisition Will Simplify Secure On-demand Access to Voice, Data and Applications from Any Device, Location or Scenario

Citrix Systems Inc. (Nasdaq:CTXS), the global leader in access infrastructure solutions, today announced it has completed the acquisition of privately held Net6 Inc., a leader in providing secure access gateways. The acquisition extends Citrix's ability to provide easy and secure access to any resource, both data and voice, on-demand.

The combination of Net6(TM) products and Citrix's existing access infrastructure solutions will enable Citrix to offer an unrivaled end-to-end access infrastructure system for voice, data and applications on a single, common gateway that can be accessed securely from a wide range of devices.

"This is another step for Citrix in our strategy to address the access infrastructure market through growth and acquisition," said Mark Templeton, president and chief executive officer for Citrix.

"Net6 technology will help us secure the last mile of computing, simplify access for users, and allow enterprises to manage and accommodate more end user access scenarios."

This acquisition accelerates, in four key ways, Citrix's strategy to define and lead the access infrastructure market:

--Net6's SSL (Secure Sockets Layer) Access Gateway will allow Citrix to offer a secure, always-on, simple and cost-effective single point-of-access that is complementary to existing Citrix(R) MetaFrame(R) solutions.

--Net6's Application Gateway(TM) product will allow Citrix to enter the market for accessing IP (Internet protocol) voice and data applications from IP screen phones, from IP-based soft phones and from small screen-factor devices like PDAs.

--Citrix gains new competencies in IP telephony, application user interface transformation and packaging of "software-as-an-appliance."

--Citrix will be able to give Net6's products broader customer exposure, international reach and the powerful Citrix brand.

On Nov. 23, 2004, Citrix announced a definitive agreement to purchase Net6 Inc. for approximately $50 million in cash. Net6 will continue to operate in San Jose, Calif., as the Citrix Gateways Division. Murli Thirumale, president and chief executive officer for Net6, will report to Mark Templeton as vice president and general manager of the division.
