WARRANT TO PURCHASE

SHARES OF STOCK OF

CLENE INC.

(Void after May 21, 2026)

This certifies that AVENUE VENTURE OPPORTUNITIES FUND, LP, a Delaware limited partnership, or permitted assigns (“Holder”), for value received, is entitled to purchase from CLENE INC., a Delaware corporation (“Company”), the Applicable Number (hereinafter defined) of fully paid and nonassessable shares of the Company’s Common Stock (the “Warrant Stock”), for cash, at a purchase price per share equal to the Stock Purchase Price (hereinafter defined). Holder may also exercise this Warrant on a cashless or “net issuance” basis as described in Section 1(b) below, and this Warrant shall be deemed to have been exercised in full on such basis on the Expiration Date (hereinafter defined), to the extent not fully exercised prior to such date. This Warrant is issued in connection with that certain Loan and Security Agreement and Supplement thereto, both of even date herewith (as amended, restated and supplemented from time to time, the “Loan Agreement” and the “Supplement”, respectively), between Company, as borrower, and Holder, as lender (“Lender”). Capitalized terms used herein and not otherwise defined in this Warrant shall have the meaning(s) ascribed to them in the Loan Agreement and the Supplement, unless the context would otherwise require.

“Applicable Number” means the number of shares of Warrant Stock purchasable hereunder obtained by dividing (A) five percent (5.00%) of the original principal amount of each Loan funded under the Loan Agreement (such amount sometimes referred to hereinafter as the “Coverage Amount”) by (B) the Stock Purchase Price; provided that, upon the funding of Tranche 2 under (and as defined in) the Supplement, and without further action of Holder or Issuer, the Applicable Number automatically shall be adjusted to include an additional number of shares of Warrant Stock (the “Tranche 2 Warrant Stock”) equal to five percent (5.00%) the original principal amount of Tranche 2, divided by the Stock Purchase Price; in each case, subject to the other adjustments set forth in Section 4 of this Warrant.

“Stock Purchase Price” means the lower of (i) the five (5)-day volume weighted average price per share; determined as of the end of trading on the last trading day before the Date of Issuance (and, in the case of any Tranche 2 Warrant Stock, as of the end of trading on the last trading day before any issuance thereof), or (ii) the Next Round Price (hereinafter defined).

“Next Round Price” means the lowest price per share paid to the Company by cash investors for the Company’s Common Stock issued in the Next Round (hereinafter defined). “Next Round” means the next bona fide round of equity financing after the Date of Issuance and on or prior to March 31, 2022, in which Company sells or issues shares of its Common Stock (excluding any option grants, shares issued in an acquisition, shares issued to vendors, and the like).

As soon as reasonably practicable after the occurrence or non-occurrence of the latest event or condition necessary to determine the Stock Purchase Price, Company shall deliver a supplement to this Warrant (subsequent to a request by Holder therefor), in substantially the form of Exhibit “A” attached hereto, specifying the total number and series of shares of Warrant Stock issuable hereunder after giving effect to the foregoing calculations, and otherwise completed with such quantity and price terms and other information as have been determined as a result of the occurrence or non-occurrence of such events or conditions. The provisions of such supplement, once completed and executed, shall control the interpretation and exercise of this Warrant; provided, however, that the failure of Company to deliver such supplement shall not affect the rights of Holder to receive the number and type of shares of Warrant Stock as set forth herein.

Subject to Section 4.3, this Warrant may be exercised at any time or from time to time up to and including 5:00 p.m. (Pacific time) on May , 2026 (the “Expiration Date”), upon surrender to Company at its principal office at 6550 South Millrock Drive, Suite G50, Salt Lake City, Utah 84121 (or at such other location as Company may advise Holder in writing) of this Warrant properly endorsed with the Form of Subscription attached hereto duly completed and signed and upon payment in cash or by check of the aggregate Stock Purchase Price for the number of shares for which this Warrant is being exercised determined in accordance with the provisions hereof. The Stock Purchase Price and the number of shares purchasable hereunder are subject to further adjustment as provided in Section 4 of this Warrant.

This Warrant is subject to the following terms and conditions:

1. Exercise; Issuance of Certificates; Payment for Shares.

(a) Unless an election is made pursuant to clause (b) of this Section 1, this Warrant shall be exercisable at the option of Holder, at any time or from time to time, on or before the Expiration Date for all or any portion of the shares of Warrant Stock (but not for a fraction of a share) which may be purchased hereunder for the Stock Purchase Price multiplied by the number of shares to be purchased. Company agrees that the shares of Warrant Stock purchased under this Warrant shall be and are deemed to be issued to Holder as the record owner of such shares as of the close of business on the date on which the form of subscription shall have been delivered and payment made for such shares. Subject to the provisions of Section 2, certificates for the shares of Warrant Stock so purchased, together with any other securities or property to which Holder is entitled upon such exercise, shall be delivered to Holder by Company at Company’s expense within a reasonable time after the rights represented by this Warrant have been so exercised. Except as provided in clause (b) of this Section 1, in case of a purchase of less than all the shares which may be purchased under this Warrant, Company shall cancel this Warrant and execute and deliver a new Warrant or Warrants of like tenor for the balance of the shares purchasable under this Warrant surrendered upon such purchase to Holder within a reasonable time. Each stock certificate so delivered shall be in such denominations of Warrant Stock as may be requested by Holder and shall be registered in the name of such Holder or such other name as shall be designated by such Holder, subject to the limitations contained in Section 2.

(b) Holder, in lieu of exercising this Warrant by the cash payment of the Stock Purchase Price pursuant to clause (a) of this Section 1, may elect, at any time on or before the Expiration Date, to surrender this Warrant and receive that number of shares of Warrant Stock computed using the following formula:

Election to exercise under this Section 1(b) may be made by delivering a signed form of subscription to Company via facsimile, to be followed by delivery of this Warrant. Notwithstanding anything to the contrary contained in this Warrant, if as of the close of business on the last business day preceding the Expiration Date this Warrant remains unexercised as to all or a portion of the shares of Warrant Stock purchasable hereunder, then effective as 9:00 a.m. (Pacific time) on the Expiration Date, Holder shall be deemed, automatically and without need for notice to Company, to have elected to exercise this Warrant in full pursuant to the provisions of this Section 1(b), and upon surrender of this Warrant shall be entitled to receive that number of shares of Warrant Stock computed using the above formula, provided that the application of such formula as of the Expiration Date yields a positive number for “X”.

(c) For purposes of Section 1(b), “Per Share Price” means:

(i) If this Warrant is exercised on the date of Company’s initial public offering of Common Stock, and if Company’s registration statement relating to such public offering has been declared effective by the Securities and Exchange Commission, then the Per Share Price shall be, if the Warrant is exercisable for Warrant Stock, the product of (A) the initial “Price to Public” of the Common Stock specified in the final prospectus with respect to the offering, and (B) the number of shares of Common Stock into which each share of Warrant Stock exercised is convertible at the date of calculation, or, if the Warrant is exercisable for Common Stock, the initial “Price to Public” of the Common Stock specified in the final prospectus with respect to the offering.

(ii) If (i) is not applicable, the Per Share Price shall be determined in good faith by the Board of Directors of Company (the “Board”) based on relevant facts and circumstances at the time of the net exercise under Section 1(b), including (a) the five (5)-day volume weighted average price per share of the Common Stock and (b) in the case of a Change of Control (as defined in Section 4.3 hereof) the consideration receivable by the holders of the Warrant Stock in such Change of Control and the liquidation preference (including any declared but unpaid dividends), if any, then applicable to the Warrant Stock.

2. Limitation on Transfer.

(a) This Warrant and the Warrant Stock shall not be transferable except upon the conditions specified in this Section 2, which conditions are intended to ensure compliance with the provisions of the Securities Act of 1933, as amended (the “Securities Act”). Each holder of this Warrant or the Warrant Stock issuable hereunder will cause any proposed transferee of the Warrant or Warrant Stock to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Section 2. Notwithstanding the foregoing and any other provision of this Section 2 but subject to the last sentence of Section 2(c), Holder may freely transfer all or part of this Warrant or the shares issuable upon exercise of this Warrant (or the securities issuable, directly or indirectly, upon conversion of the shares, if any) at any time to any affiliate of Lender under the Loan Agreement, by giving Company notice of the portion of the Warrant being transferred setting forth the name, address and taxpayer identification number of the transferee and surrendering this Warrant to Company for reissuance to the transferees(s) (and Holder, if applicable).

(b) Each certificate representing (i) this Warrant, (ii) the Warrant Stock and (iii) any other securities issued in respect to the Warrant Stock upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall (unless otherwise permitted by the provisions of this Section 2 or unless such securities have been registered under the Securities Act or sold under Rule 144) be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend required under applicable state securities laws):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE AND DISTRIBUTION THEREOF, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OR ANY STATE SECURITIES LAWS. SUCH SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF (A) SUCH REGISTRATION, (B) AN OPINION OF COUNSEL IN A FORM REASONABLY ACCEPTABLE TO COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED DUE TO AN EXEMPTION THEREFROM UNDER SAID ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR (C) CLENE INC. OTHERWISE SATISFIES ITSELF THAT SUCH TRANSACTION IS COMPLIANT WITH SUCH LAWS.

(c) Holder of this Warrant and each person to whom this Warrant is subsequently transferred represents and warrants to Company and agrees (by acceptance of such transfer) that it will not transfer this Warrant (or securities issuable upon exercise hereof unless a registration statement under the Securities Act was in effect with respect to such securities at the time of issuance thereof) unless (i) there is an effective registration statement under the Securities Act and applicable state securities laws covering any such transaction, (ii) pursuant to Rule 144 under the Securities Act (or any other rule under the Securities Act relating to the disposition of securities), (iii) Company receives an opinion of counsel, reasonably satisfactory to Company, that an exemption from such registration is available or (iv) the Company otherwise satisfies itself that such transaction is exempt from registration. Notwithstanding the foregoing or any other provision of this Section 2, Holder shall not transfer this Warrant (or securities issuable upon exercise hereof, or securities issuable, directly or indirectly, upon conversion of such securities, if any) to any competitor of Company, as determined in good faith by the Board, without the prior written consent of Company.

(d) [Reserved].

(e) As a condition to the exercise of this Warrant and the issuance of Warrant Stock, if requested by the Company by reasonable notice to Holder, Holder shall agree in writing to be fully bound by any investors rights, shareholder or similar agreements applicable to holders of Warrant Stock (“Investor Agreements”), provided that Holder shall not be required to agree to any terms of such agreements that are inconsistent with the terms of this Warrant.

3. Shares to be Fully Paid; Reservation of Shares. Company covenants and agrees that all shares of Warrant Stock which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be duly authorized, validly issued, fully paid and nonassessable and free from all preemptive rights of any stockholder and free of all taxes (except any tax imposed on Holder with respect to the gain on the exercise of the Warrant), liens and charges with respect to the issue thereof. Company further covenants and agrees that during the period within which the rights represented by this Warrant may be exercised, Company will at all times have authorized and reserved, for the purpose of issue or transfer upon exercise of the subscription rights evidenced by this Warrant, a sufficient number of shares of authorized but unissued Warrant Stock, or other securities and property, when and as required to provide for the exercise of the rights represented by this Warrant. Company will take all such action as may be necessary to assure that such shares of Warrant Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any domestic securities exchange upon which the Warrant Stock may be listed. Company will not take any action which would result in any adjustment of the Stock Purchase Price (as described in Section 4 hereof) (i) if the total number of shares of Warrant Stock issuable after such action upon exercise of all outstanding warrants, together with all shares of Warrant Stock then outstanding and all shares of Warrant Stock then issuable upon exercise of all options and upon the conversion of all convertible securities then outstanding, would exceed the total number of shares of Warrant Stock then authorized by Company’s Certificate of Incorporation, as amended and restated from time to time (the “Charter”), (ii) if the total number of shares of Common Stock issuable after such action upon the conversion of all such shares of Warrant Stock together with all shares of Common Stock then outstanding and then issuable upon exercise of all options and upon the conversion of all convertible securities then outstanding would exceed the total number of shares of Common Stock then authorized by Company’s Charter or (iii) if the par value per share of the Warrant Stock would exceed the Stock Purchase Price.

4. Adjustment of Stock Purchase Price and Number of Shares. The Stock Purchase Price and the number of shares purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events described in this Section 4. Upon each adjustment of the Stock Purchase Price, Holder of this Warrant shall thereafter be entitled to purchase, at the Stock Purchase Price resulting from such adjustment, the number of shares obtained by multiplying the Stock Purchase Price in effect immediately prior to such adjustment by the number of shares purchasable pursuant hereto immediately prior to such adjustment, and dividing the product thereof by the Stock Purchase Price resulting from such adjustment.

4.1 Subdivision or Combination of Stock. In case Company shall at any time subdivide its outstanding shares of Warrant Stock into a greater number of shares, the Stock Purchase Price in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, in case the outstanding shares of Warrant Stock of Company shall be combined into a smaller number of shares, the Stock Purchase Price in effect immediately prior to such combination shall be proportionately increased.

4.2 Dividends. If at any time or from time to time the holders of Warrant Stock (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received or become entitled to receive,

(a) Warrant Stock, or any shares of stock or other securities whether or not such securities are at any time directly or indirectly convertible into or exchangeable for Warrant Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution,

(b) any cash paid or payable including as a cash dividend, or

(c) Warrant Stock or other or additional stock or other securities or property (including cash) by way of spin off, split-up, reclassification, combination of shares or similar corporate rearrangement, (other than shares of Warrant Stock issued as a stock split, adjustments in respect of which shall be covered by the terms of Section 4.1 above), then and in each such case, Holder hereof shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Warrant Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to in clauses (b) and (c) above) which such Holder would hold on the date of such exercise had it been the holder of record of such Warrant Stock as of the date on which holders of Warrant Stock received or became entitled to receive such shares and/or all other additional stock and other securities and property.

4.3 Change of Control. In the event of a Change of Control (as hereinafter defined) that occurs after the date this Warrant is issued, this Warrant shall be automatically exchanged for a number of shares of Company’s securities, such number of shares being equal to the maximum number of shares issuable pursuant to the terms hereof (after taking into account all adjustments described herein) had Holder elected to exercise this Warrant immediately prior to the closing of such Change of Control and purchased all such shares pursuant to the cash exercise provision set forth in Section 1(a) hereof (as opposed to the cashless exercise provision set forth in Section 1(b)). Company acknowledges and agrees that Holder shall not be required to make any payment (cash or otherwise) for such shares as further consideration for their issuance pursuant to the terms of the preceding sentence. “Change of Control” shall mean any sale, license, or other disposition of all or substantially all of the assets of Company, any reorganization, consolidation, merger or other transaction involving Company where the holders of Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction; provided that an issuance of equity securities for the primary purpose of raising capital shall not be considered a Change of Control under this Warrant. This Warrant shall terminate upon Holder’s receipt of the number of shares of Company’s equity securities described in this Section 4.3.

4.4 Reserved.

4.5 Notice of Adjustment. Upon any adjustment of the Stock Purchase Price, and/or any increase or decrease in the number of shares purchasable upon the exercise of this Warrant, Company shall give written notice thereof to Holder pursuant to Section 12. The notice, which may be substantially in the form of Exhibit “A” attached hereto, shall be signed by Company’s chief financial officer and shall state the Stock Purchase Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

4.6 Other Notices. If at any time:

(a) Company shall declare any cash dividend upon its Warrant Stock;

(b) Company shall declare any dividend upon its Warrant Stock payable in stock or make any special dividend or other distribution to the holders of its Warrant Stock;

(c) Company shall offer for subscription pro rata to the holders of its Warrant Stock any additional shares of stock of any class or other rights;

(d) there shall be any capital reorganization or reclassification of the capital stock of Company, or consolidation or merger of Company with, or sale of all or substantially all of its assets to, another entity;

(e) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of Company; or

(f) Company shall take or propose to take any other action, notice of which is actually provided to holders of the Warrant Stock;

then, in any one or more of said cases, Company shall give Holder, pursuant to Section 12, (i) at least 10 days’ prior written notice of the date on which the books of Company shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, or other action and (ii) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, or other action, at least 10 days’ written notice of the date when the same shall take place. Any notice given in accordance with the foregoing clause (i) shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Warrant Stock shall be entitled thereto. Any notice given in accordance with the foregoing clause (ii) shall also specify the date on which the holders of Warrant Stock shall be entitled to exchange their Warrant Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, or other action as the case may be.

4.7 Certain Events. If any change in the outstanding Warrant Stock of Company or any other event occurs as to which the other provisions of this Section 4 are not strictly applicable or if strictly applicable would not fairly effect the adjustments to this Warrant in accordance with the essential intent and principles of such provisions, then the Board shall make in good faith an adjustment in the number and class of shares issuable under this Warrant, the Stock Purchase Price and/or the application of such provisions, in accordance with such essential intent and principles, so as to protect such purchase rights as aforesaid. The adjustment shall be such as will give Holder of this Warrant upon exercise for the same aggregate Stock Purchase Price the total number, class and kind of shares as Holder would have owned had this Warrant been exercised prior to the event and had Holder continued to hold such shares until after the event requiring adjustment.

5. Issue Tax. The issuance of certificates for shares of Warrant Stock upon the exercise of this Warrant shall be made without charge to Holder of this Warrant for any issue tax in respect thereof; provided, however, that Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the then Holder of this Warrant being exercised, and the Holder shall pay any tax imposed on Holder with respect to the gain on the exercise of the Warrant.

6. Closing of Books. Company will at no time close its transfer books against the transfer of this Warrant or of any shares of Warrant Stock issued or issuable upon the exercise of this Warrant in any manner which interferes with the timely exercise of this Warrant unless the Company at the same time is closing its transfer books for all Common Stock.

7. No Voting Rights; Limitation of Liability. Nothing contained in this Warrant shall be construed as conferring upon Holder hereof the right to vote or to consent as a stockholder in respect of meetings of stockholders for the election of directors of Company or any other matters or any rights whatsoever as a stockholder of Company. No dividends or interest shall be payable in respect of this Warrant or the interest represented hereby or the shares purchasable hereunder until, and only to the extent that, this Warrant shall have been exercised; provided, however, that if any dividends are due or paid at any time on the underlying securities for which this Warrant is exercisable, then upon exercise, the securities issued to Holder shall be deemed to have accrued dividends and be paid identical dividends from the same time as the outstanding shares for which this Warrant is exercisable were first issued (or, if later, the date of this Warrant). No provisions hereof, in the absence of affirmative action by Holder to purchase shares of Warrant Stock, and no mere enumeration herein of the rights or privileges of Holder hereof, shall give rise to any liability of such Holder for the Stock Purchase Price or as a stockholder of Company, whether such liability is asserted by Company or by its creditors.

8. Amendment of Charter. Unless Holder consents thereto in writing, Company shall not amend its Charter prior to the exercise of this Warrant if the Warrant Stock would be adversely affected by such amendment in a manner that would be more adverse to Holder with respect to the shares of Warrant Stock issuable upon the exercise of this Warrant than, and substantially dissimilar to, such amendment’s effect on the other holders of the same class or series of Warrant Stock.

9. Registration Rights. The Company will use commercially reasonable efforts to include in a registration statement on Form S-1, currently in good faith anticipated to be filed by the Company with the SEC in connection with a PIPE transaction within ninety days, the Warrant Stock issuable upon exercise of this Warrant. Thereafter, the Company will use commercially reasonable efforts to maintain a registration statement under which the Warrant Stock could be issued until the Warrant is exercised or expires.

10. Rights and Obligations Survive Exercise of Warrant. The rights and obligations of Company, of Holder of this Warrant and of the holder of shares of Warrant Stock issued upon exercise of this Warrant, contained in Sections 6, 8, 9 and 19 shall survive the exercise of this Warrant.

11. Modification and Waiver. This Warrant and any provision hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of the same is sought.

12. Notices. Any notice, request or other document required or permitted to be given or delivered to Holder or Company shall be deemed to have been given (i) upon receipt if delivered personally or by courier (ii) upon confirmation of receipt if by telecopy or (iii) three business days after deposit in the US mail, with postage prepaid and certified or registered, to each such Holder at its address as shown on the books of Company or to Company at the address indicated therefor in the opening paragraphs of this Warrant (or at such other location as Company may advise Holder in writing).

13. Survival of Certain Obligations. All of the obligations of Company relating to the Warrant Stock issuable upon the exercise of this Warrant shall survive the exercise and termination of this Warrant. All of the covenants and agreements of Company shall inure to the benefit of and be binding upon the successors and permitted assigns of Holder. Company will, at the time of the exercise of this Warrant, in whole or in part, upon request of Holder but at Company’s expense, acknowledge in writing its continuing obligation to Holder in respect of any rights to which Holder shall continue to be entitled after such exercise in accordance with this Warrant; provided, that the failure of Holder to make any such request shall not affect the continuing obligation of Company to Holder in respect of such rights.

14. Descriptive Headings and Governing Law. The descriptive headings of the several sections and paragraphs of this Warrant are inserted for convenience only and do not constitute a part of this Warrant. This Warrant shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the laws of the State of Delaware.

15. Lost Warrants or Stock Certificates. Company agrees that upon receipt of evidence reasonably satisfactory to Company of the loss, theft, destruction, or mutilation of any Warrant or stock certificate and, in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to Company, or in the case of any such mutilation upon surrender and cancellation of such Warrant or stock certificate, Company at its expense will make and deliver a new Warrant or stock certificate, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant or stock certificate.

16. Fractional Shares. No fractional shares shall be issued upon exercise of this Warrant. Company shall, in lieu of issuing any fractional share, pay the holder entitled to such fraction a sum in cash equal to such fraction multiplied by the then effective Stock Purchase Price.

17. Representations of Holder. With respect to this Warrant, Holder represents and warrants to Company as follows:
