Mr. Michael D. Monahan
1063 Nelson Court
Pleasanton, CA 94566

Dear Mike:

It is my great pleasure to offer you the position of Vice President of Sales for
Sonix Technologies, Inc., reporting directly to the President & CEO. You will
have full responsibility for building and directing the sales force, for
developing a sales strategy and for executing it. Mike, you will also function
as a senior member of the executive management team and apply a broad range of
business skills to help me run the enterprise. Together, we will build Sonix
Technologies into the most exciting, customer-satisfying company in the history
of hearing health care.

The terms of this offer include the following:

1.  Base salary will be $140,000 per year, paid twice-monthly.

2.  You will be paid a one time hiring bonus of $20,000 upon the beginning of
    your employment with Sonix.

3.  Benefits include vacation, holidays, medical insurance for you and your
    dependents (fully paid by Sonix), dental insurance and a 401k plan.

4.  At the first Board of Directors meeting after you begin employment, I will
    ask the Board to grant you an option to purchase 110,000 shares of common
    stock at the fair market price established by the Board on the date of
    grant. The grant will be subject to the standard terms and conditions of the
    Company's Stock Option Agreement. Your shares will vest over four years, the
    first 25% on the date of your first anniversary of employment at Sonix; the
    remainder in equal installments over the subsequent 36 month period.

5.  In the event of an acquisition of greater than 50% ownership by another
    industrial entity for the purposes of commercial exploitation of the Sonix
    technology during the option period, shares described above shall vest
    immediately. This accelerated vesting applies only to that portion of the
    original option remaining at the time of acquisition. If no such acquisition
    occurs as indicated, you will be bound by the standard, four year vesting
    provision of the Sonix Stock Option Agreement.

6.  The Company will pay reasonable and customary relocation expenses for your
    move to the Salt Lake City area, including real estate commissions on both
    ends, moving of household goods, travel, and temporary housing as
    appropriate.

7.  Employment at Sonix is not for a specific term and can be terminated by you
    or by the Company at any time, for any reason, with or without cause and
    with or without notice. If you choose to terminate your employment before
    completing one full year at Sonix, you agree to repay the hiring bonus and
    relocation costs.

8.  It shall be a condition of your employment that you execute the Company's
    standard non-disclosure agreement concerning confidentiality and
    intellectual property rights, and that you will not bring to Sonix any
    proprietary technology or information from any third party.

9.  Sonix anticipates your start date to be approximately March 2, 1998. This
    offer of employment expires February 13, 1998. Please sign a copy of this
    letter, indicating your acceptance, and return it to me at your earliest
    convenience.

Mike, you and I have an opportunity to help the hearing impaired as they have
never been helped before.  Imagine the satisfaction we will feel in 5 years,
having built the best hearing aid company in the world and having created the
most satisfied customers in the history of the industry.  Please join me for the
challenge and the fun!

Sincerely,

/s/ Andrew G. Raguskus/ by Debbie Thomas
