Thomas:

I am pleased to confirm a formal job offer to have you join FieldWorks as its
President and Chief Executive Officer upon closing of the Kontron transaction
and the immigration approval, anticipated by December 1, 2000.

Our offer to you is based upon our ability to pay which should be assured with
the closing of the Kontron transaction. Specifically, we are offering an
annualized base pay of $140,000, payable bi-weekly, plus a management incentive
bonus of $10,000 per quarter upon achievement of quarterly objectives. In
addition, an initial stock option of 200,000 shares at the market price on the
day of the grant, with vesting occurring as follows:

                         25% upon acceptance of position
                         25% vest at two years
                         25% vest at three years
                         25% vest at four years

This significant stock option should put you in position to potentially achieve
a large gain as the company grows.

A company car will be provided for you.

A signing bonus of $17,500 will be paid to you on December 1, 2000.

To assist in your relocation, FieldWorks will provide you with:

                  up to $1,000 per month
          o       An incremental expense payment of $15,000 to cover all the
                  miscellaneous costs associated with selling your home and
                  possessions in Sweden as well as all the one-time costs for
                  establishing residence in the U.S.
          o       Transportation of you and your family to the U.S.
