 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, Schweichler Associates LLC, together with any registered holder from time to time of this Warrant, “Holder”) is entitled to
purchase the number of fully paid and nonassessable shares of the class of securities (the “Shares”) of the Company at the Warrant Price, all as set forth above and as adjusted pursuant to Article 2 of this Warrant, subject to the
provisions and upon the terms and conditions set forth in this Warrant. 
 ARTICLE 1 

EXERCISE 
 1.1 Method of Exercise. Holder may exercise this Warrant by delivering a duly executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company.
Holder shall also deliver to the Company a wire transfer (to an account designated by the Company), or other form of payment acceptable to the Company, for the aggregate Warrant Price for the Shares being purchased. 

1.2 Delivery of Certificate and New Warrant. Promptly after Holder exercises this Warrant and the Company receives
payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this Warrant has not been fully exercised and has not expired, a new Warrant representing the Shares not so acquired.

 1.3 Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation upon surrender and

ARTICLE 2 

ADJUSTMENTS TO THE SHARES 
 2.1 Reclassification, Exchange, Combinations or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a change of the number and/or class of the securities
issuable upon exercise of this Warrant, Holder shall be entitled to receive, upon exercise of this Warrant, the number and kind of securities and property that Holder would have received for the Shares if this Warrant had been exercised


  
 1. 









 
immediately before such reclassification, exchange, substitution, or other event. The Company or its successor shall promptly issue to Holder an amendment to this Warrant setting forth the number
and kind of such new securities or other property issuable upon exercise of this Warrant as a result of such reclassification, exchange, substitution or other event that results in a change of the number and/or class of securities issuable upon
exercise of this Warrant. The amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Article 2.1 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events. 

2.2 Fractional Shares. No fractional Shares shall be issuable upon exercise of this Warrant and the number of
Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise of the Warrant, the Company shall eliminate such fractional share interest by paying Holder the amount computed by
multiplying the fractional interest by the fair market value of a full Share. 
 2.3 Certificate as to
Adjustments. Upon each adjustment of the Warrant Price, the Company shall promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with a certificate setting forth such
adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the series of adjustments leading to such Warrant
Price. 
 ARTICLE 3 
 REPRESENTATIONS AND COVENANTS OF THE COMPANY

Holder will be acquired for investment for Holder’s account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Act. Holder also represents that Holder has not been formed for the
specific purpose of acquiring this Warrant or the Shares. 
 4.2 Disclosure of Information. Holder has
received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity

could acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder has access. 
 4.3 Investment Experience. Holder understands that the purchase of this Warrant and its underlying securities involves substantial risk. Holder has experience as an investor in securities of
companies in the development stage and acknowledges that Holder can bear the economic risk of such Holder’s investment in this Warrant and its underlying securities and has such knowledge and experience in financial or business matters that


  
 2. 









 
Holder is capable of evaluating the merits and risks of its investment in this Warrant and its underlying securities and/or has a preexisting personal or business relationship with the Company
and certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons.

promulgated under the Act. 
 4.5 The Act. Holder understands that this Warrant and the Shares issuable
upon exercise hereof have not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Holder’s investment intent as expressed herein. Holder
understands that this Warrant and the Shares issued upon any exercise hereof must be held indefinitely unless subsequently registered under the Act and qualified under applicable state securities laws, or unless exemption from such registration and
qualification are otherwise available. Holder acknowledges that the Company has no obligation to register or qualify the Shares.

Stockholders Agreements. If the Company has any agreement or agreements to which the holders of the Shares are a party or otherwise bound at the time of exercise of this Warrant (each such agreement, a “Stockholder Agreement”), Holder
acknowledges and agrees that Holder must execute and become a party to each such Stockholder Agreement as a condition to exercising this Warrant. A copy of any such agreements, if such agreements are in effect, will be available upon request to the
Chief Financial Officer of the Company. Holder acknowledges that as of the date of issuance of this Warrant, the holders of the Shares are party to or otherwise bound by that certain Amended and Restated Stockholder Agreement, dated as of

its terms. 
 5.10 Early Termination. In the event of, at any time during the Exercise Period, an
IPO or a Corporate Transaction (as hereinafter defined), then the Company shall provide to Holder ten (10) business days advance written notice of the IPO or Corporate Transaction, and this Warrant shall terminate unless exercised prior to the
date of such IPO or Corporate Transaction. For purposes of this Section 5.10: (i) “IPO” means the Company’s first underwritten public offering of its Common Stock under the Act; and (ii) a “Corporate
Transaction” means either (a) a transaction or series of related transactions in which a person, or group of related persons, acquires from stockholders of the Company shares representing more than 50% of the outstanding voting power of

 4. 









 5.11 “Market Stand-Off” Agreement. Holder hereby
agrees that it will not, without the prior written consent of the managing underwriter, during the Market Stand-Off Period (as hereinafter defined), (a) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase;
purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares of the Company’s common stock or any securities convertible into or exercisable or
exchangeable (directly or indirectly) for the Company’s common stock held immediately before the effective date of the registration statement for such offering or (ii) enter into any swap or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of the Company’s common stock or other securities, in
cash, or otherwise. The foregoing provisions of this Section 5.11 shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement. The underwriters in connection with such registration are intended third-party
beneficiaries of this Section 5.11 and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. Holder further agrees to execute such agreements as may be reasonably requested by the
underwriters in connection with such registration that are consistent with this Section 5.11 or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions
with respect to this Warrant or the Shares until the end of such restricted period. For purposes of this Section 5.11: (i) “Market Stand-Off Period” means the period of time commencing on the date of the final prospectus relating
to the registration by the Company of shares of its common stock or any other equity securities under the Act on a registration statement on Form S-1, Form S-2, or Form S-3, and ending on the date specified by the Company and the managing
underwriter (such period not to exceed (a) one hundred eighty (180) days in the case of the IPO, which period may be extended upon the request of the managing underwriter, to the extent required by any Financial Industry Regulatory
Authority (“FINRA”) rules, for an additional period of up to fifteen (15) days if the Company issues or proposes to issue an earnings or other public release within fifteen (15) days of the expiration of the 180-day lockup
period, or (b) ninety (90) days in the case of any registration other than the IPO, which period may be extended upon the request of the managing underwriter, to the extent required by any FINRA rules, for an additional period of up to
fifteen (15) days if the Company issues or proposes to issue an earnings or other public release within fifteen (15) days of the expiration of the 90-day lockup period); and (ii) “IPO” means the Company’s first
underwritten public offering of its common stock under the Act. 
 5.12 Business Days. As used in this
Warrant, “business day” means a day other than a Saturday, Sunday, or other public holiday under the laws of the State of Colorado.
