 Exhibit 10.9 
  
 SONIC INNOVATIONS, INC. 
  
 EMPLOYMENT AGREEMENT 
  
 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 with the Company’s normal payroll practices. The Base
Salary shall be reevaluated yearly but in no event reduced. 
 

 1 

  
 (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

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 due to (i) a voluntary termination by the Employee for “Good Reason” (as defined 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 with the Company, 100% of the Shares subject to the First Option shall vest and become immediately
exercisable. 
  
 (b)    Option Vesting in Connection with a Termination Occurring Within
One Year.    If, prior to the first annual anniversary of the Effective Date, Employee’s employment with the Company or his status as Chairman of the Board terminates due to (i) a voluntary termination by the Employee
for “Good Reason” (as defined 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 with the Company, 1/7 of the Shares subject to the Second
Option and 1/7 of the Shares subject to the Third Option shall vest and become immediately exercisable. 
  
 (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 
 

 3 

  
 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 have the following meanings:

his responsibilities as an employee and intended to result in personal enrichment of himself or his associates at the expense of the Company or its stockholders, (ii) committing an act of fraud against the Company, (iii) conviction of, or plea of
nolo contendere to, a felony by the Employee, (iv) continued violations of the Employee’s employment-related obligations which are willful and deliberate after there has been delivered to the Employee a written demand from the Board
regarding such 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 immediately after such merger or consolidation; (iv) a change in the composition of the Board
occurring within a two (2)-year period, such that a majority of the then current Board members ceases to be comprised of individuals who either (a) have been Board members continuously since the beginning of such period, or (b) have been elected or
nominated for election as Board members during such period by at least a majority of the Board members described in clause (a) who were still in office at the time such election or nomination was approved by the Board.

“Disability” shall mean the Employee’s inability to substantially perform his essential job functions as the result of a physical or mental disability as determined by a qualified physician or incapacity for a period of 180 days,
consecutive or otherwise, in any 360-day period. 
  
 (d)    Good
Reason.    Resignation for “Good Reason” shall mean any of the 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 entitled, (iv) the conviction of, or plea of nolo contendere to, a felony by the Company, except where the Employee has knowingly participated in such felony, (v) the failure of the Company to maintain an effective Directors and
Officers indemnification insurance policy that includes the Employee under its coverage, or (vi) continued violations of the Company’s employment-related obligations to Employee which are willful and deliberate after there has been delivered to
the Board a written demand from the Employee regarding such activities. 
  
 8.    Right to Advice of
Counsel.    The Employee acknowledges that he has consulted with counsel and is fully aware of his rights and obligations under this Agreement and of the tax consequences thereof.

obligations in the absence of a succession. For all purposes under this Agreement, the term “Company” shall include any successor to the Company’s business or assets which executes and delivers the assumption agreement described in
this subsection (a) or which becomes bound by the terms of this Agreement by operation of law. 
  
 (b)     Employee’s Successors.    Without the written consent of the Company, the Employee shall not assign or transfer this Agreement or any right or obligation under this Agreement to
