Dear Brad:

As discussed during your recent interviews with WFI, we are a rapidly growing
company seeking above average professionals wishing to contribute their skills
and talents in an entrepreneurial environment of growth and individual success.

We believe you to be that type of individual, and are therefore pleased to offer
you the position of General Counsel and Vice President, Legal Affairs, reporting
to Massih Tayebi, Chief Executive Officer, in San Diego, CA. This letter is our
formal offer of employment and requires your written acceptance within ten days
of the date of this letter. If you accept this offer, we expect you to begin
work at WFI as soon as possible.

Your monthly salary will be $12,500 ($150,000 annualized) paid semi-monthly,
commencing on your actual date of employment and subject to such withholdings as
required by law. Your position is considered exempt, and therefore, you are not
eligible for overtime payments. Based on your work performance and WFI annual
financial performance, you may be eligible for a bonus of up to 50% of your base
salary at the Company's sole discretion on an annual, pro-rata calendar year
basis beginning for the year 1999. You must be on the active payroll at the time
of payment in the year 2000 in order to qualify.

WFI will pay for the expense for you to apply for the California State Bar

California State Bar exam. Total expense related to this effort is limited to
$2,000. Additionally, WFI will reimburse, through the normal course of business
expense submittal, the costs of your membership in the American Bar Association,
the Washington State Bar Association, and the American Corporate Counsel
Association, as well as the reasonable cost of education requirements to
maintain such memberships as approved pursuant to normal Company policies.


WFI will pay for your physical relocation of household goods and auto to the San
Diego area by a corporate mover selected by WFI. Additionally, WFI will
reimburse you up to six (6) months living allowance ($1,700 per month); up two
(2) months automobile rental of a standard mid-size if necessary; up to 4 round

necessary to carry out your obligations to WFI.
