                                       And
                          Centurion International Inc.

Centurion agrees to design an internal antenna assembly for the Dell L2 laptop
computer project. The antenna assembly will meet a mutually agreed upon
mechanical and electrical performance specification. Centurion will provide
Dell with test measurement data and functional antenna assembly samples to
establish and confirm the performance.

The antenna assembly will consist of a 2.4 GHz single element with attached
coaxial cable terminated to a PCB with a Hirose connector. Reference Centurion
print #CAF95885.

Centurion will apply antenna technology and intellectual property and will
offer the design to Dell with no charge for non-recurring engineering
development. Should the design be acceptable, Dell will agree to purchase from
Centurion a minimum of [*****] over a period of [*****] from the start of
manufacturing at a price of no more than $[*****]. Volumes and price after the
first year will be negotiated.

Should a second production source be assigned using the Centurion design, Dell
agrees to assign a minimum of [*****]% the production volume to Centurion and
pay a royalty of [*****]% of purchase price to Centurion on all antennas
purchased from the second source.

Dell agrees that if the design is accepted and less than [*****] is purchased
within [*****], or Centurion is assigned less than [*****]% of the production
volume (minimum of [*****] annually), Dell will pay Centurion, engineering
development costs of $[*****], and a royalty of [*****]% of the selling price on
all antennas purchased from all other sources for the L2 program.

If the Centurion design is not accepted, Dell agrees to return all samples and
documents associated with the project with the terms and conditions of NDA #
99121607 continue in effect.

Centurion will retain the rights and ownership of the antenna technology and
intellectual property developed by Centurion and used for this design.
