(PR Newswire; 09/01/98)

ORLANDO, Fla., Sept. 1 /PRNewswire/ -- Caldera today announced at Thinergy '98 
 the availability of Caldera's compact, Year 2000-compliant embedded operating 
 system, DR-DOS, with Citrix Systems, Inc.'s (Nasdaq: CTXS) Independent 
 Computing Architecture (ICA ).  The combination of DR-DOS and Citrix's ICA 
 technology provides a thin client solution for Citrix MetaFrame and WinFrame 
 thin client/server environments.  With DR-WebSpyder (Caldera's graphical HTML 
 browser) and Caldera's TCP/IP stack, OEMs have a full connectivity solution for 
 embedded x86 devices, such as Internet set-tops, network computers, interactive 
 kiosks, smart phones and Internet appliances.

 "Caldera continues to aggressively enhance DR-DOS with technologies for the 
 embedded market," said Roger Gross, general manager of Caldera, Inc.'s Thin 
 Client Division.  "By joining DR-DOS and Citrix ICA, Caldera and Citrix have 
 created the ideal, low-risk platform for a new class of powerful, low-resource 
 thin clients."

 Janice Roberts, director of client business development at Citrix, Inc., said, 
 "DR-DOS is a proven platform for thin client vendors seeking a reliable, 
 compact solution.  The existence of thousands of DOS engineers and DOS 
 development tools greatly simplifies the integration and delivery of DR-DOS- 
 based ICA thin clients."

 The advanced extended memory management capabilities of DR-DOS creates an 
 extremely flexible execution environment for developers utilizing Citrix's ICA 
 technology in 32-bit protected mode implementations.
