Software Component Pricing and Licensing

National delivers and supports a complete software solu-

tion when paired up with the WindowsCE.net or Linux

operating system. The delivered software is a compilation

of software created by National Semiconductor, Philips

Semiconductors and Microsoft. Customers may need sep-

arate pricing and support agreements for Windows Media

Technology (Microsoft), BIOS, Operating System, and mid-

dleware. National’s pricing excludes fundamental patents:

MPEG-1, -2, -4 (MPEG-LA) and MP3 (Thomson Multime-
