     This Employment Agreement (the "Agreement") is entered into by and between
Sonic Innovations, Inc., a Delaware corporation (the "Company"), and Kevin Ryan
(the "Employee") as of December __, 2001.

     WHEREAS, the Company desires to employ the Employee on a part-time basis in
the capacity of Chairman of the Board of Directors (the "Board") of the Company,
and the Employee desires to accept such employment; and

     WHEREAS the parties desire and agree to enter into an employment
relationship by means of this Agreement;

     NOW THEREFORE in consideration of the promises and mutual covenants herein
contained, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, it is mutually covenanted and
agreed by the parties as follows:

     1.   Position and Duties. The Employee shall be employed as Chairman of the
Board, an officer position, reporting solely to the Board but coordinating his
efforts with those of the CEO, and assuming and discharging such duties and
responsibilities as are commensurate with the Employee's position. The Employee
shall perform his duties faithfully and to the best of his ability and shall
devote approximately 60% his business time and effort (except for permitted
vacation periods and periods of illness and other incapacity) to the performance
of his duties hereunder. The Employee may perform such duties at such locations
as he and the Board deem reasonably appropriate. The Employee shall commence
employment with the Company effective January 1, 2002 (the "Effective Date").

     2.   Term of Employment. The Employee's employment with the Company shall
continue until terminated by either party at any time upon thirty days' prior
written notice for any or no reason. In the event of an involuntary termination
for Cause or a voluntary termination for Good Reason, such notice period shall
be deemed to have begun upon the delivery of a notice under Section 7(a) or
Section 7(d). The parties agree and acknowledge that this Agreement is an "at
will" agreement and that no implied covenant or standard of practice will cause
this Agreement to have any minimum period of employment.

     3.   Compensation.

          (a)  Base Salary. For all services to be rendered by the Employee to
the Company while this Agreement is in effect, the Employee shall receive a
minimum annual base salary equal to $200,000.00 (the "Base Salary"), subject to
applicable tax withholding and payable in accordance
<PAGE>

with the Company's normal payroll practices. The Base Salary shall be
reevaluated yearly but in no event reduced.

          (b)  Reimbursement of Expenses. The Company shall reimburse Employee
for all out-of-pocket expenses reasonably incurred and paid by him in the
performance of his duties pursuant to this Agreement, in accordance with Company
policies adopted from time to time.

benefits and perquisites as the Company generally provides to its senior
executives.

     6.   Change of Control and Termination.

          (a)  Option Vesting in Connection with a Change of Control. If, on or
within 12 months after a "Change of Control" (as defined below), Employee's
employment with the Company or his status as Chairman of the Board terminates

below), where the grounds for the Good Reason are not cured within 30 days
following receipt of written notice from Employee specifying the grounds, or
(ii) an involuntary termination by the Company other than for "Cause" (as
defined below), death or "Disability" (as defined below), then, subject to
Employee executing and not revoking a standard form of mutual release of claims

          (c)  Limitation on Payments. In the event that any payment or benefit
received or to be received by the Employee in connection with a Change of
Control or the termination of the Employee's employment (the "Total Payments")
would subject the Employee to the excise tax or any interest or penalties with
respect to such excise tax (such excise tax, interest and penalties are
collectively referred to as the "Excise Tax") imposed under Section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code"), and the net after-tax
amount receivable by the Employee is less than the net after-tax amount that
could otherwise be payable to the Employee without the imposition of the Excise
Tax, then to the extent necessary to eliminate the imposition of the Excise Tax,
such Total Payments shall be reduced in the following order by the least amount
which results in the Employee not being subject to the Excise Tax: Total
Payments payable in cash shall first be reduced (if necessary, to zero) and
Total Payments in connection with any option shall next be reduced. For purposes
of this limitation, no portion of the Total Payments shall be taken into account
that, in the opinion of tax counsel selected by the Company and reasonably
acceptable to the Employee, does not constitute a "parachute payment" within the
meaning of Section 280G(b)(2) of the Code, including by reason of Section
280G(b)(4)(A) (or successor provisions as then in effect).

     7.   Definitions. For purposes of this Agreement, the following terms shall

felony by the Employee, (iv) continued violations of the Employee's employment-
related obligations which are willful and deliberate after there has been

activities or (v) willful refusal to carry out legally permissible instructions
from the Board after the Employee has been given written notice of a failure to
carry out such instructions and a reasonable opportunity to correct the
situation.

          (b)  Change of Control. A "Change of Control" shall mean (i) the sale,
lease, conveyance or other disposition of all or substantially all of the
Company's assets as an entirety or substantially as an entirety to any "person"
(as such term is used in Section 13(d) of the Securities Exchange Act of 1934,
as amended), entity or group of persons acting in concert; (ii) any "person"
becoming the "beneficial owner" (as defined in Rule 13d-3 under said Act),
directly or indirectly, of securities of the Company representing 50% or more of
the total voting power represented by the Company's then outstanding voting
securities; (iii) a merger or consolidation of the Company with any other
corporation, other than a merger or consolidation that would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity or its controlling entity) at
least 50% of the total voting power represented by the voting securities of the
Company or such surviving entity (or its controlling entity) outstanding

following without the Employee's written consent: (i) any material diminution or
material adverse change in the Employee's position with the Company, duties,
responsibilities or the positions that report directly to him, (ii) a reduction
by the Company in Employee's Base Salary, (iii) a material reduction in the
aggregate program of employee benefits and perquisites to which Employee is

to all or substantially all of the Company's business or assets shall assume the

least 50% of the total voting power represented by the voting securities of the
Company or such surviving entity (or its controlling entity) outstanding
