Dear Scott:

It is my pleasure to offer you the position of Chief Operating Officer at Biodesix, Inc. (“Biodesix” or the “Company”) beginning on March 1, 2018. As Chief Operating Officer you will be reporting to David Brunel, Chief Executive Officer, who will be primarily responsible for evaluating your performance. In this position you will be overseeing our organization’s ongoing operations and procedures with the goal of securing the functionality of business to drive extensive and sustainable growth. You will work primarily from our Boulder facility. The Company may change your position, title, duties, and place of employment from time to time as it deems necessary.

This letter and the accompanying enclosures state the complete terms and conditions of your offer. This offer will expire if not accepted within two weeks of the date of this letter, shown above.

Our benefits, payroll, and other human resource management services are provided through TriNet Employer Group, Inc., a professional employer organization. As a result of Biodesix’s arrangement with TriNet, TriNet will be considered your employer of record for these purposes, and your managers at Biodesix will be responsible for directing your work, reviewing your performance, and setting your schedule at Biodesix.

Compensation: Your base salary will be $22,916.67 per month, or $275,000 annualized, less all deductions and withholdings. Salaries are paid twice per month. The Company may modify your compensation from time to time in its sole discretion.

Mobile Phone Allowance: In addition to the salary above, you will receive a taxable mobile phone allowance of $125 per month. This allowance is intended to cover business use of your personal cell phone.

the Board approves and grants such option (“Option”). The vesting schedule and all terms, conditions, and limitations of the Option will be set forth in a stock option grant notice, the Company’s standard stock option agreement and the Company’s 2016 Equity Incentive Plan. You must be employed by the Company on the date the Options are approved.

Bonus: You have the potential of achieving a bonus of up to 50% of your base salary (as actually paid in a given year) if you achieve certain milestones and objectives determined by the Company. Such bonus, if any, will be paid after the close of the Company’s financial year, after validation and approval from the Company’s Board of Directors that relevant objectives have been achieved, and provided the Company has the financial wherewithal to pay. To be eligible for any Bonus, you must have begun your employment with the Company on or before September 30 of the year for which the Bonus is awarded, and you must be employed by the Company at the time any Bonus amount is to be paid. Bonuses are not earned until they are approved in writing by the Board of Directors of the Company.

Benefits: Upon acceptance of full-time employment, you will also be eligible to receive the same benefits available to all US employees of the Company which include vacation and sick leave, health insurance, dental insurance, a vision plan, and any other benefit plans offered by the Company. Full-time employees are entitled to 8 days of sick leave per year, which you will be eligible to use commencing with your first day of employment at the Company. Your annual vacation will be 20 days per year, which will accrue upon commencement of employment. If any sick days are unused at the end of the year they will not carry over to the following year. Vacations must be scheduled in consultation with your supervisor in order to minimize the disruption to the Company’s business. In general, one week’s notice should be provided for each day off requested. The Company may modify your benefits from time to time in its sole discretion.

Confidentiality and Inventions Assignment Agreement: One of the conditions of your employment with the Company is the maintenance of the confidentiality of the Company’s proprietary and confidential information. In your work for the Company, you will be expected not to use or disclose any confidential information, including trade secrets, of any former employer or other person to whom you have an obligation of confidentiality. Rather, you will be expected to use only that information that is generally known and used by persons with training and experience comparable to your own, which is common knowledge in the industry or otherwise legally in the public domain or which is otherwise provided or developed by the Company. You also should not bring onto the Company premises any unpublished documents or property belonging to any former employer or other person to whom you have an obligation of confidentiality. During our discussions about your proposed job duties, you assured us that you would be able to perform those duties within the guidelines described above. Before your start date, you must therefore execute the Company’s Confidentiality and Inventions Assignment Agreement (“CIIA”), which you will find attached hereto as Attachment A. However, your commencement of employment shall constitute acceptance of all the terms and conditions in the Company’s Confidentiality and Inventions Assignment Agreement.

Expenses: The Company will reimburse you for reasonable and necessary expenses incurred by you in furtherance of Biodesix’ business. All expenses claimed are subject to the review and

Code 409A Compliance. To the extent any payments or benefits pursuant to this offer letter Agreement are paid from the date of termination of your employment through March 15 of the calendar year following such termination, such Severance Payments are intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations and thus payable pursuant to the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations, (b) are paid following said March 15, such Severance Payments are intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations made upon an involuntary separation from service and payable pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations, to the maximum extent permitted by said provision, (c) represent the reimbursement or payment of costs for outplacement services, such payments are intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations and to qualify for the exception from deferred compensation pursuant to Section 1.409A-1(b)(9)(v)(A), and (d) are in excess of the amounts specified above, such Severance Payments shall (unless otherwise exempt under Treasury Regulations) be considered separate payments subject to the distribution requirements of Section 409A(a)(2)(A) of the Internal Revenue Code of 1986, as amended (the “Code”), including the requirement of Section 409A(a)(2)(B)(i) of the Code that payments or benefits be delayed until 6 months after your separation from service if you are a “specified employee” within the meaning of such section of the Code at the time of such separation from service.

Name & Likeness Rights: You hereby authorize the Company to use, reuse, and to grant others the right to use and reuse your name, Company-originated photograph, Company-originated voice recording, biographical information relevant to your professional status, and any reproduction or simulation thereof, in any media now known or hereafter developed (including but not limited to film, video, and digital, or other electronic media), both during and after your employment.

At-Will Employment: As Biodesix is the company for which you will perform service, we will retain the right to control and direct your work, its results, and the manner and means by which your work is accomplished. Your employment with the Company is at will, and therefore, may be terminated by you or the Company at any time and for any reason, with or without cause, and with or without notice. Any contrary representations or agreements, which may have been made to you, are superseded by this offer. The “at will” nature of your employment described in this offer letter shall constitute the entire agreement between you and the Company concerning the nature and duration of your employment. In addition, the fact that the rate of your salary or other compensation is stated in units of years or months and that your vacation and sick leave accrue annually or monthly does not alter the at-will nature of the employment, and does not mean and should not be interpreted to mean that you are guaranteed employment to the end of any period of time or for any period of time. The “at will” term of your employment with the Company can only be changed in writing and signed by you and the Chief Executive Officer of the Company.

Exempt Employment: As an exempt, salaried employee, you will be expected to work additional hours as required by the nature of your work assignments.
