•DUTIES. You shall serve and shall perform such duties as are customarily associated with the positions of Chief Financial Officer and Chief Business Officer and such other duties as are assigned to you by your supervisor, the Company’s Chief Executive Officer. Your job duties and responsibilities may change from time to time, without advance notice, in the sole discretion of the Company. You shall work remotely from your home office in Colorado, subject to such travel as is reasonably required in connection with your duties. This is an exempt position.

During the term of your employment, you shall devote your full working time and attention to the business affairs of the Company; provided, however, that, subject to the terms of the Company’s form of Proprietary Information and Inventions Assignment Agreement, as described below, this shall not preclude you from (a) devoting time to personal and family investments, (b) participating in industry associations, (c) serving on community and civic boards, (d) serving on up to one for-profit board (or such greater number as approved by the Board), or (e) serving as an advisor, or as a member of an advisory board, to up to two organizations (or such greater number as approved by the Board); provided such activities do not interfere with your duties to the Company, as determined in good faith by the board of directors of the Company (the “Board”).

◦BASE SALARY. You will receive an annual base salary of $415,000 for all hours worked after such date, less taxes, authorized withholdings and other legally required deductions. You will be paid in accordance with the Company’s customary payroll procedures as established and modified from time-to-time. Following the consummation of the Company’s Series B preferred stock financing (or a similar, commensurate financing), your annual base salary will be reviewed and evaluated for adjustments based on comparable company benchmarking data.

◦ANNUAL BONUS. In addition to your base salary, you may be eligible to earn, for each fiscal year of the Company ending during the term of your employment with the Company, an annual cash performance bonus under the Company’s bonus plan, as approved from time to time by the Board. Your target annual bonus will be 40% of your base salary for the year to which such annual bonus relates (your “Target Bonus”). Your actual annual bonus will be determined on the basis of your and/or the Company’s attainment of financial or

other performance criteria established by the Board or its designee in accordance with the terms and conditions of such bonus plan. You must be employed by the Company on the date of payment of such annual bonus in order to be eligible to receive such annual bonus. You hereby acknowledge and agree that nothing contained herein confers upon you any right to an annual bonus in any year, and that whether the Company pays you an annual bonus and the amount of any such annual bonus will be determined by the Company in its sole discretion. Your bonus for 2022 will be calculated based on your annual Base Salary and will not be prorated from your commencement of employment.

◦STOCK OPTIONS. Subject to approval of the Board, you will be granted an option to purchase 1,862,058 shares of common stock of the Company at an exercise price per share equal to the fair market value per share of the Company’s common stock on the date of grant (the “Initial Award”). Upon consummation of the Company’s Series B preferred stock financing, you will be provided an additional grant of options bringing you back to 1.2% of the fully diluted shares of the Company after giving effect to such financing and the Initial Award (the “Additional Award”). The Initial Award and Additional Award will be granted pursuant to the Company’s equity incentive plan (the “Plan”), and will be subject to the terms and conditions of the Plan and your stock option agreement. The Initial Award and Additional Award will vest over a four year vesting schedule, with 25% of such Awards vesting on the first anniversary of your Start Date and the remaining portion of such Awards vesting in 36 monthly installments thereafter. The Initial Award and Additional Award will vest upon a Change in Control (as defined below). At your request, the Initial Award and Additional Award can be issued as an equal number of shares in the form of restricted stock, as opposed to stock options, on similar vesting terms.

◦BENEFITS. You shall be eligible to participate in all of the employee benefit plans or programs the Company generally makes available to similarly situated employees, pursuant to the terms and conditions of such plans. You will also be entitled to vacation and/or paid time off each year in accordance with Company policy and all holidays observed by the Company each year. The Company reserves the right to change compensation and benefits provided to its employees from time to time in its discretion.

◦ACCRUED OBLIGATIONS. If your employment terminates for any reason, you are entitled to your fully earned but unpaid base salary, through the date such termination is effective at the rate then in effect, and all other amounts or benefits to which you are entitled under any compensation, retirement or benefit plan of the Company at the time of your termination of employment in accordance with the terms of such plans, including, without limitation, any accrued but unpaid paid time off and any continuation of benefits required by applicable law (the “Accrued Obligations”).

◦SEVERANCE BENEFITS. In addition to your Accrued Obligations, subject to your continued compliance with the Proprietary Information and Inventions Assignment Agreement, as described below, and the effectiveness of your Release, as defined below, if your employment is involuntarily terminated by the Company without Cause (as defined below) (and other than by reason of your death or disability) or you resign for Good Reason (as defined below) (either such termination, a “Qualifying Termination”), you shall be entitled to receive, as the sole severance benefits to which you are entitled, the benefits provided below (the “Severance Benefits”):

•If you are terminated between January 1 and the payment date of the your annual cash performance bonus for the calendar year preceding the date of your Qualifying Termination, you will be paid a lump sum cash payment in an amount equal to the amount of the annual cash performance bonus that you would have otherwise earned for performance in the calendar year preceding your termination, which amount will be paid in a lump sum within 10 days following the date your Release becomes effective;

date on which you become eligible to receive the equivalent or increased healthcare coverage by means of subsequent employment or self-employment) (such period, the “COBRA Coverage Period”), if you and/or your eligible dependents who were covered under the Company’s health insurance plans as of the date of your termination of employment elect to have COBRA coverage and are eligible for such coverage, the Company shall pay for or reimburse you on a monthly basis for an amount equal to (i) the actual monthly premium you and/or your covered dependents, as applicable, are required to pay for continuation coverage pursuant to COBRA for you and/or your eligible dependents, as applicable, who were covered under the Company’s health plans as of the date of your termination of employment. If any of the Company’s health benefits are self-funded as of the date of your termination of employment, or if the Company cannot provide the foregoing benefits in a manner that is exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), or that is otherwise compliant with applicable law (including, without limitation, Section 2716 of the Public Health Service Act), instead of providing the payments or reimbursements as set forth above, the Company shall instead pay to you lump sum amount in advance for the COBRA Coverage Period (or any remaining portion thereof). You shall be solely responsible for all matters relating to continuation of coverage pursuant to COBRA, including, without limitation, the election of such coverage and the timely payment of premiums. You shall notify the Company immediately if you become eligible to receive the equivalent or increased healthcare coverage by means of subsequent employment or self-employment;

•Notwithstanding anything else set forth herein, in the Plan or in any award agreement, such number of the unvested Stock Awards (as defined below) then held by you (including the Initial Award and Additional Award) will vest on the effective date of your Release as would have vested during the 9-month period following your Qualifying Termination had you remained employed by the Company during such period. The foregoing provisions are hereby deemed to be a part of each Stock Award and to supersede any less favorable provision in any agreement or plan regarding such Stock Award; and

•In the event your Qualifying Termination occurs within 3 months prior to, or on or within 12 months following a Change in Control, the foregoing severance benefits shall be revised as follows: (a) the references to “9 months” in the foregoing severance provisions shall be increased to “12 months,” with 9 months’ base salary to be paid as provided above and the additional 3 months’ base salary to be paid in a lump sum within 10 days following the later of (i) the date your Release becomes effective or (ii) the date of the Change in Control, (b) in addition to the prorated Target Bonus described above, you will receive an additional amount equal to (i) 100% of your Target Bonus for the calendar year in which your Qualifying Termination occurs, less (ii) the prorated Target Bonus to be paid as

◦As a condition to your receipt of any post-termination payments and benefits pursuant to the preceding paragraphs, you shall execute and not revoke a general release of all claims in favor of the Company (the “Release”) in a form reasonably acceptable to the Company in order to effectuate a valid general release of claims. In the event the Release does not become effective within the 60-day period following the date of your termination of employment, you will not be entitled to the aforesaid payments and benefits.

◦For purposes of this Agreement, “Cause” means any of the following: (a) your commission of an act of fraud, embezzlement or dishonesty, or the commission of some other illegal act by you, that has a demonstrable adverse impact on the Company or any successor or affiliate thereof; (b) your conviction of, or plea of “guilty” or “no contest” to, a felony or any crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (c) any intentional, unauthorized use or disclosure by you of confidential information or trade secrets of the Company or any successor or affiliate thereof; (d) your gross negligence, insubordination or material violation of any duty of loyalty to the Company or any successor or affiliate thereof, or any other demonstrable material misconduct on your part; (e) your ongoing and repeated failure or refusal to perform or neglect of your duties as required by this Agreement or your ongoing and repeated failure or refusal to comply with the instructions given to you by the Board, which failure, refusal or neglect continues for 15 days following your receipt of written notice from the Board stating with specificity the nature of such failure, refusal or neglect; or (f) your willful, material breach of any material Company policy or any material provision of this Agreement or the Proprietary Information and Inventions Assignment Agreement. Prior to the determination that “Cause” under clauses (d), (e) or (f) has occurred, the Company shall (i) provide to you in writing, in reasonable detail, the reasons for the determination that such “Cause” exists, (ii) other than with respect to clause (e) above which specifies the applicable period of time for you to remedy your breach, afford you a reasonable opportunity to remedy any such breach, (iii) provide you an opportunity to be heard prior to the final decision to terminate your employment hereunder for such “Cause” and (iv) make any decision that such “Cause” exists in good faith. The foregoing definition shall not in any way preclude or restrict the right of the Company or any successor or affiliate thereof to discharge or dismiss you for any other acts or omissions, but such other acts or omissions shall not be deemed, for purposes of this Agreement, to constitute grounds for termination for Cause.

◦For purposes of this Agreement, “Good Reason” means any of the following without your written consent: (a) a material diminution in your authority, duties or responsibilities; (b) a material diminution in your base compensation or annual cash target bonus opportunity (and you and the Company agree that any diminution of 10% or more shall be considered material for this purpose, regardless of whether such diminution occurs due to a single reduction or a series of reductions in your base compensation), unless such a reduction is imposed across-the-board to senior management of the Company; (c) a material change in the geographic location at which you must perform your duties; or (d) any other action or inaction that constitutes a material breach by the Company or any successor or affiliate of its obligations to you under this Agreement. You must provide written notice to the Company of the occurrence of any of the foregoing events or conditions without your written consent within 60 days of the occurrence of such event. The Company or any successor or affiliate shall have a period of 30 days to cure such event or condition after receipt of written notice of such event from you. Your termination of employment by reason of resignation from employment with the Company for Good Reason must occur within 30 days following the expiration of the foregoing 30-day cure period.

◦To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder. The intent of the parties is that payments and benefits under this Agreement comply with, or be exempt from Section 409A of the Code and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance with such intention. To the extent that any provision in this Agreement is ambiguous as to its compliance with or exemption from Section 409A of the Code, the provision shall be read in such a manner that no payments payable under this Agreement shall be subject to an “additional tax” as defined in Section 409A(a)(1)(B) of the Code. For purposes of Section 409A of the Code, any right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments. For purposes of this Agreement, all references to your “termination of employment” shall mean your “separation from service” (as defined in Treasury Regulation Section 1.409A-1(h)) (“Separation from Service”). If you are a “specified employee” (as defined in Section 409A of the Code), as determined by the Company in accordance with Section 409A of the Code, on the date of your Separation from Service, to the extent that the payments or benefits under this Agreement are “non-qualified deferred compensation” subject to Section 409A of the Code and the delayed payment or distribution of all or any portion of such amounts to which you are entitled under this

Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, then such portion deferred pursuant to this paragraph shall be paid or distributed to you in a lump sum on the earlier of (a) the date that is 6 months and one day following your Separation from Service, (b) the date of your death or (c) the earliest date as is permitted under Section 409A of the Code. Any remaining payments due under this Agreement shall be paid as otherwise provided herein.

◦To the extent that the payments or benefits under this Agreement are “non-qualified deferred compensation” subject to Section 409A of the Code, if the period during which you may deliver the Release required hereunder spans two calendar years, the payment of your post-termination benefits shall occur (or commence) on the later of (a) January 1 of the second calendar year, or (b) the first regularly-scheduled payroll date following the date your Release becomes effective.

◦Any reimbursement of expenses or in-kind benefits payable under this Agreement shall be made in accordance with Treasury Regulation Section l.409A-3(i)(1)(iv) and shall be paid on or before the last day of your taxable year following the taxable year in which you incurred the expenses. The amount of expenses reimbursed or in-kind benefits payable in one year shall not affect the amount eligible for reimbursement or in-kind benefits payable in any other taxable year of yours, and your right to reimbursement for such amounts shall not be subject to liquidation or exchange for any other benefit.

•COMPANY POLICIES AND PROPRIETARY INFORMATION AND INVENTIONS ASSIGNMENT AGREEMENT. As an employee of the Company, you shall be expected to abide by all of the Company’s policies and procedures and the Company’s employee handbook, if any. As a condition of your employment, you agree to execute and abide by the terms of the Company’s form of the Proprietary Information and Inventions Assignment Agreement, which shall survive termination of your employment with the Company and the termination of this Proprietary Information and Inventions Assignment Agreement. You acknowledge that a remedy at law for any breach or threatened breach by you of the provisions of the Proprietary Information and Inventions Assignment Agreement would be inadequate, and you therefore agree that the Company shall be entitled to injunctive relief in case of any such breach or threatened breach. The Company may modify, revoke, suspend or terminate any of the terms, plans, policies and/or procedures described in the employee handbook, if any, or as otherwise communicated to you, in whole or part, at any time, with or without notice.

bound by any non-compete or non-solicitation agreement or any other type of agreement that would prohibit your employment with the Company. You agree not to make any unauthorized disclosure or use, on behalf of the Company, of any confidential information belonging to any of your former employers. You also represent that you are not in unauthorized possession of any materials containing a third party’s confidential and proprietary information. While employed by the Company, you will not engage in any business activity in competition with the Company nor make preparations to do so. In the event that you wish to undertake a business activity outside the scope of your employment by the Company, which activity you believe entails no conflict with the Company’s activities, you agree to inform the Company of your intentions before the initiation of such outside business activity, and you furthermore agree to abide by the Company’s decision as to whether or not there is no conflict. If, in the Company’s sole determination, a conflict exists or is likely to develop, you agree not to undertake such outside business activity.

•AT-WILL EMPLOYMENT. Your employment with the Company will be “at-will” at all times, including after your introductory, probationary period, meaning that either you or the Company will be entitled to terminate your employment at any time and for any reason, with or without cause. Any contrary representations that may have been made to you are superseded by this offer. This Agreement in no way represents a fixed-term employment contract. This is the full and complete agreement between you and the Company on this term. Although your job duties, title, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time, the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the Company.

•NON-INTERFERENCE. While employed by the Company, and for one (1) year immediately following the date on which you terminate employment or otherwise cease providing services to the Company, you agree not to interfere with the business of the Company by soliciting or attempting to solicit any employee or consultant of the Company to terminate such employee’s or consultant’s employment or service in order to become an employee, consultant or independent contractor to or for any other person or entity. The foregoing restrictions shall not apply with respect to (a) the bona fide hiring and firing of Company personnel to the extent such acts are part of your duties for Company or (b) a general advertisement or solicitation (or any hiring pursuant to such advertisement or solicitation) that is not specifically targeted to such employees or consultants. Your duties under this paragraph shall survive termination of your employment with the Company and the termination of this Agreement.

•REASONABLENESS OF TERMS. You agree that the terms contained in the “Other Agreements” and “Non-Interference” paragraphs above are reasonable in all respects and that the restrictions contained therein are designed to protect the Company against unfair competition. In the event a court determines that any of the terms or provisions of this Agreement are unreasonable, the court may limit the application of any provision or term, or modify any provision or term, and proceed to enforce this Agreement as so limited or modified.

•GOVERNING LAW; JURISDICTION AND VENUE. This Agreement, for all purposes, shall be construed in accordance with the laws of the State of Colorado without regard to conflicts-of-law principles. Any action or proceeding by either party to enforce this Agreement shall be brought only in any state or federal court located in Jefferson County, Colorado. The parties hereby irrevocably submit to the exclusive jurisdiction of such courts and waive the defense of inconvenient forum to the maintenance of any such action or proceeding in such venue.

•SEVERABILITY. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provisions had never been contained herein.

•ENTIRE AGREEMENT. This Agreement and the Proprietary Information and Inventions Assignment Agreement constitute the complete, final and exclusive embodiment of the entire agreement between you and the Company with respect to the terms and conditions of your employment specified herein and therein. This Agreement and the Proprietary Information and Inventions Assignment Agreement supersede any other such promises, obligations, warranties, representations or agreements between you and the Company, and you agree that any and all such prior promises, obligations, warranties, representations and agreements are hereby terminated. This Agreement may not be amended or modified except by a written instrument signed by you and a duly authorized officer of the Company.
