COMMON STOCK PURCHASE WARRANT

JAGUAR HEALTH, INC.

Warrant Shares:               1

Date of Issuance: [·], 2019 (“Issuance Date”)

This COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received (in connection with the funding of the purchase price of $[·] under that certain promissory note in the original principal amount of $[·] (the “Note”) on [·], 2019 by the Company (as defined below) to the Holder (as defined below)), [·], [a [·] company]/ /[an individual resident of the State of [·]] (including any permitted and registered assigns, the “Holder”), is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the date of issuance hereof, to purchase from Jaguar Health, Inc., a Delaware corporation (the “Company”), up to [·] shares of Common Stock (as defined below) (the “Warrant Shares”) (whereby such number may be adjusted from time to time pursuant to the terms and conditions of this Warrant) at the Exercise Price (as defined below) per share then in effect. This Warrant is issued by the Company as of the Issuance Date in connection with that certain Securities Purchase Agreement dated [·], 2019, by and between the Company and the Holder (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase Agreement”).

Capitalized terms used in this Warrant shall have the meanings set forth in the Purchase Agreement unless otherwise defined in the body of this Warrant or in Section 15 below. For purposes of this Warrant, the term “Exercise Price” with respect to the Warrant Shares issued hereunder shall mean, subject to adjustment under Section 2 below, the per share price at which the Company issues Common Stock in the next underwritten public offering that is the subject of a registration statement on Form S-1; provided, however, that if the Company has not consummated such an offering by the four-month anniversary of the Issuance Date, then the Exercise Price shall be equal to the Closing Sale Price (as defined below) of the shares of Common Stock (as reported by Bloomberg Financial Markets) on the four-month anniversary of the Issuance Date, and the term “Exercise Period” shall mean the period commencing on the Issuance Date and ending on the Expiration Date (as defined in Section 6 below).

1  NTD: The number of warrant shares shall be equal to (a) [  ]% of the principal amount set forth on the promissory note, divided by (b) the Exercise Price.

1.                                      EXERCISE OF WARRANT.

(a)                                 Exercise. Subject to the terms and conditions hereof, the purchase rights represented by this Warrant may be exercised by the Holder, in whole or in part, by the surrender of this Warrant (with the notice of exercise form attached hereto as Exhibit A duly executed (the “Exercise Notice”)), at the principal office of the Company, and by the payment to the Company, by certified cashier’s or other check acceptable to the Company or wire transfer, of an amount equal to the aggregate Exercise Price of the Warrant Shares being purchased.

(b)                                 Stock Certificates. In the event of any exercise of the rights represented by this Warrant, certificates for the Warrant Shares so purchased shall be delivered to the Holder within a reasonable time and, unless this Warrant has been fully exercised or has expired, a new Warrant representing the shares with respect to which this Warrant shall not have been exercised shall also be issued to the Holder within such time.

(c)                                  No Fractional Shares. No fractional shares shall be issued in connection with any exercise hereunder. All Warrant Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, make a cash payment therefor based upon the fair market value of the Warrant Shares as determined by the Company.

(d)                                 Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, to the extent that after giving effect to issuance of Warrant Shares upon exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s affiliates, and any other persons acting as a group together with the Holder or any of the Holder’s affiliates), would beneficially own in excess of the Beneficial Ownership Limitation, as defined below. For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, non-exercised portion of this Warrant beneficially owned by the Holder or any of its affiliates and (ii) exercise or conversion of the unexercised or non-converted portion of any other securities of the Company (including without limitation any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this paragraph (d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this paragraph applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination.

For purposes of this paragraph, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the SEC, as the case may be, (B) a more

2

recent public announcement by the Company or (C) a more recent written notice by the Company or its transfer agent setting forth the number of shares of Common Stock outstanding. Upon the request of a Holder, the Company shall within two Trading Days confirm to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The limitations contained in this paragraph shall apply to a successor Holder of this Warrant. The Company covenants that this Warrant is outstanding, the Company will reserve from its authorized and unissued Common Stock a number of shares, free from preemptive rights, equal to three times the number of shares that is actually issuable upon full exercise of the Warrant (based on the Exercise Price in effect at that time).

Notwithstanding anything in this Warrant to the contrary, and in addition to the Beneficial Ownership Limitation described above, the Company and Holder agree that the total cumulative number of shares of Common Stock that may be issued to Holder under this Warrant, together with any shares of Common Stock issued to holders of warrants in the same series of transactions as this Warrant, may not exceed the requirements of The Nasdaq Capital Market (including the rules related to the aggregation of offerings under Nasdaq Listing Rule 5635(d) if applicable) (the “Exchange Cap”), unless (i) stockholder approval is obtained to issue more than the Exchange Cap or (ii) the Common Stock is not listed for quotation on Nasdaq or NYSE American. The Exchange Cap shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction.

2.                                      ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES.  Subject to the provisions of Section 6 hereof, the Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2 as follows:

(a)                                 Reclassification.  In case of any reclassification or change of the Common Stock (other than a change in par value, or as a result of a subdivision or combination or dividend or as otherwise as adjusted under this Section 2), the Company shall execute a new Warrant, providing that the holder of this Warrant shall have the right to exercise such new Warrant, and procure upon such exercise and payment of the same aggregate Exercise Price, in lieu of the shares of Common Stock theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification or change by a holder of an equivalent number of shares of Common Stock.  Such new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 2.  Except for a Liquidation Event (as defined in Section 6), the provisions of this subsection (a) shall similarly apply to successive reclassifications and changes.

(b)                              Stock Splits and Combinations. If the Company, at any time while this Warrant is outstanding (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides its outstanding shares of Common Stock into a larger number of shares, or (iii) combines its outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately before such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this Section 2(b) shall become effective immediately after the effective date of such subdivision or combination.

3

(c)                                  Pro Rata Distributions.  If the Company, at any time while this Warrant is outstanding, distributes to all holders of Common Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (in each case, “Distributed Property”), then, upon any exercise of this Warrant that occurs after the record date fixed for determination of stockholders entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Warrant Shares otherwise issuable upon such exercise (if applicable), the Distributed Property that such Holder would have been entitled to receive in respect of such number of Warrant Shares had the Holder been the record holder of such Warrant Shares immediately prior to such record date.

(d)                                 Number of Warrant Shares.  Simultaneously with any adjustment to the Exercise Price pursuant to this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

3.                                      RESTRICTIONS UPON TRANSFER.

(a)                                 The Company need not register a transfer of this Warrant unless the conditions specified in the legends on the front page hereof are satisfied and the transferee has agreed in writing to be subject to the terms and conditions of this Warrant, including transferee acknowledging in writing that it meets the investor suitability criteria set forth in this Warrant and Exhibit B attached hereto. Subject to the satisfaction of such conditions, any transfer of this Warrant and all rights hereunder, in whole or in part (but not less than 25% of the Warrant Shares originally exercisable under this Warrant being transferred), shall be registered on the books of the Company to be maintained for such purpose, upon surrender of this Warrant at the principal office of the Company, or the office or agency designated by the Company, together with a written assignment of this Warrant substantially in the form of Exhibit C hereto duly executed by Holder and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall, subject to the conditions set forth in this Section, execute and deliver a new Warrant in the name of the assignee, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be canceled.

(b)                                 The Company shall prepare, issue and deliver at its own expense (other than transfer taxes) the new Warrant or Warrants under this Section 3.

4.                                      RESTRICTIVE LEGENDS.

(a)                                 The Warrant Shares issuable upon exercise of this Warrant (unless registered under the Securities Act of 1933, as amended (the “Securities Act”)) shall be stamped or imprinted with legends in substantially the following form:

AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH SALE, OFFER, PLEDGE OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT AND OF ANY APPLICABLE STATE SECURITIES LAWS. COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

(b)                                 The Company need not register a transfer of Warrant Shares bearing the restrictive legends set forth in this Section 4, unless the conditions specified in such legends are satisfied. The Company may also instruct its transfer agent not to register the transfer of the Warrant Shares, unless all of the conditions specified in the legends set forth in this Section 4 are satisfied.

5.                                      RIGHTS OF STOCKHOLDERS. No holder of this Warrant shall be entitled, as a Warrant holder, to vote or receive dividends or be deemed the holder of Common Stock or any other securities of the Company which may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the holder of this Warrant, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until the Warrant shall have been exercised and the Warrant Shares purchasable upon the exercise hereof shall have become deliverable, as provided herein.

(a)                                 after 5:30 p.m., Pacific time, on [·], 20242;

(b)                                 the closing of (i) a merger, reorganization, tender offer or similar transaction involving the Company or its securities with or into another entity in which the holders of voting securities of the Company immediately prior to such transaction will hold less than 50% of the voting securities of the surviving entity immediately following such transaction as a result of shares held prior to such transaction or (ii) a sale or license of all or substantially all of the assets of the Company (each, a “Fundamental Transaction”),  provided that, such termination shall be effected by delivery of written notice to the Holder regarding such termination, and such written notice shall include an option for the Holder to choose, in its sole discretion, to exercise this Warrant in lieu of termination at that time; and

(c)                                  a “Liquidation Event” as defined in the Company’s Certificate of Designation of Series A Convertible Participating Preferred Stock, provided that, such termination shall be effected by delivery of written notice to the Holder regarding such termination, and such written notice shall include an option for the Holder to choose, in its sole discretion, to exercise this Warrant in lieu of termination at that time.

7.                                      NON-CIRCUMVENTION.

5

voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, for so long as this Warrant is outstanding, have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock issuable under the Warrant to provide for the exercise of the rights represented by this Warrant (without regard to any limitations on exercise).

8.                                      WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, this Warrant, in and of itself, shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

9.                                      REISSUANCE.

(a)                                 Lost, Stolen or Mutilated Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company will, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

(b)                                 Issuance of New Warrants.

Promptly upon receiving such written notice, the Company shall present copies thereof to the Company’s counsel. If the proposed transfer may be effected without registration or qualification (under any federal or state securities laws), the Company, as promptly as practicable, shall notify the Holder thereof, whereupon the Holder shall be entitled to transfer this Warrant or to dispose of Warrant Shares received upon the previous exercise of this Warrant, all in accordance with the terms of the notice delivered by the Holder to the Company; provided, however, that an appropriate legend may be endorsed on this Warrant or the certificates for such Warrant Shares respecting restrictions upon transfer thereof necessary or advisable in the opinion of counsel and satisfactory to the Company to prevent further transfers which would be in violation of Section 5 of the Securities Act and applicable state securities laws; and provided further that the prospective transferee or purchaser shall execute the Assignment of Warrant attached hereto as Exhibit C and such other documents and make such representations, warranties, and agreements as may be required solely to comply with the exemptions relied upon by the Company for the transfer or disposition of the Warrant or Warrant Shares.

(b)                                 If the proposed transfer or disposition of this Warrant or such Warrant Shares described in the written notice given pursuant to this Section 10 may not be effected without registration or qualification of this Warrant or such Warrant Shares, the Holder will limit its activities in respect to such transfer or disposition as are permitted by law.

6

(c)                                  Any transferee of all or a portion of this Warrant shall succeed to the rights and benefits of the initial Holder of this Warrant under the Purchase Agreement (registration rights, expenses, and indemnity).

11.                               NOTICES. Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in accordance with the notice provisions contained in the Purchase Agreement. The Company shall provide the Holder with prompt written notice at least 7 days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any stock or other securities directly or indirectly convertible into or exercisable or exchangeable for shares of Common Stock or other property, pro rata to the holders of shares of Common Stock or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder.

13.                               GOVERNING LAW.  This Warrant shall be governed by and interpreted in accordance with the laws of the State of Delaware without regard to the principles of conflicts of law (whether of the State of Delaware or any other jurisdiction).

14.                               ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.

15.                               CERTAIN DEFINITIONS. For purposes of this Warrant, the following terms shall have the following meanings:

If the Closing Sale Price cannot be calculated for a security on a particular date on any of the foregoing bases, the Closing Sale Price of such security on such date shall be the fair market value as determined by the Company’s Board of Directors in good faith. All such determinations shall be appropriately adjusted for any stock dividend, stock split, stock combination or other similar transaction during the applicable calculation period.

(b)                                 “Common Stock” means the Company’s voting common stock, par value $0.0001 per share, and any other class of securities into which such securities may hereafter be reclassified or changed.

INVESTMENT REPRESENTATION STATEMENT

In connection with the purchase of the above referenced shares (the “Securities”), the undersigned represents to the Company the following:

The undersigned is aware of the Company’s business affairs and financial condition, and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities.  The undersigned is purchasing these Securities for its own account for investment purposes only and not with a view to, or for the resale in connection with, any “distribution” thereof for purposes of the Securities Act of 1933, as amended (the “Securities Act”).

The undersigned understands that offer and sale of the Securities have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the undersigned’s investment intent as expressed herein.  In this connection, the undersigned understands that, in the view of the Securities and Exchange Commission (the “SEC”), the statutory basis for such exemption may be unavailable if this representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future.

The undersigned further understands that the Securities must be held indefinitely unless the offer and sale of the Securities are subsequently registered under the Securities Act or unless an exemption from registration is otherwise available.  Moreover, the undersigned understands that the Company is under no obligation to register the offer and sale of the Securities.  In addition, the undersigned understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities unless the offer and sale of the Securities are registered or such registration is not required in the opinion of counsel for the Company.

The undersigned is familiar with the provisions of Rule 144, promulgated pursuant to the Securities Act, which, in substance, permits limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions.

The Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires, among other things, the existence of a public market for the Securities, the availability of certain current public information about the Company, the resale occurring not less than one year after a party has purchased and paid for the security to be sold, the sales being effected through a “broker’s transaction” or in transactions directly with a “market maker” and the number of Securities being sold during any three-month period not exceeding specified limitations.

The undersigned further understands that in the event that all of the applicable requirements of Rule 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rule 144 is not exclusive, the Staff of the SEC has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.

The undersigned hereby ratifies and confirms all of the original Holder’s representations and warranties set forth in Section 3 of the Purchase Agreement, including but not limited to that the undersigned is an “Accredited Investor” as set forth in the Warrant and is not a “Bad Actor”  as set forth in the Warrant and if the undersigned is not a United States person as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended (the “Code”)), Holder hereby represents that Holder has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Securities or any use of the Warrant, including (i) the legal requirements within its jurisdiction for the purchase of the Securities, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any government or other consents that may need to be obtained in connection with such purchase, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Securities.  Holder’s purchase and payment for and continued beneficial ownership of the Warrant Shares will not violate any applicable securities or other laws of Holder’s jurisdiction. Holder acknowledges that no representations or warranties, oral or written, have been made by the Company or any agent thereof in connection with Holder’s exercise of this Warrant.

EXHIBIT C

ASSIGNMENT OF WARRANT

(To be signed only upon authorized transfer of the Warrant)

FOR VALUE RECEIVED, the undersigned hereby sells, assigns, and transfers unto                             the right to purchase                       shares of voting common stock of Jaguar Health, Inc., to which the within Common Stock Purchase Warrant relates and appoints                        , as attorney-in-fact, to transfer said right on the books of Jaguar Health, Inc. with full power of substitution and re-substitution in the premises.
