Common Stock Warrant

Surna Inc., a Nevada corporation (the “Company”), for value received, hereby certifies that ____________________, or its registered assigns (the “Registered Holder”), is entitled, subject to the terms set forth below, to purchase from the Company at any time after the Date of Issuance and on or before December ___, 2020 (the “Expiration Date”), _______ shares (as adjusted from time to time pursuant to the provisions of this Warrant) of common stock, par value $0.00001 per share, of the Company (the “Common Stock”), at an exercise price of $0.20 per share. The shares issuable upon exercise of this Warrant and the exercise price per share, as adjusted from time to time pursuant to the provisions of this Warrant, are sometimes hereinafter referred to as the “Warrant Shares” and the “Exercise Price,” respectively.

This Warrant is issued pursuant to that certain Securities Purchase Agreement dated as of December 12, 2017 by and among the Company and the purchasers signatory thereto (the “Purchase Agreement”). Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Purchase Agreement.

1. Exercise

a. Exercise By Registered Holder. At any time on or after the Date of Issuance and on or before the Expiration Date, this Warrant may be exercised by the Registered Holder, in whole or in part, by surrendering this Warrant, with the purchase/exercise form attached hereto as Exhibit A (the “Notice of Exercise”) duly executed by the Registered Holder or by the Registered Holder’s duly authorized attorney, at the principal office of the Company, or at such other office or agency as the Company may designate, accompanied by payment in full of the aggregate Exercise Price payable in respect of the number of Warrant Shares purchased upon such exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. Notwithstanding anything herein to the contrary, the Registered Holder shall not be required to physically surrender this Warrant to the Company until the Registered Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Registered Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Registered Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases, provided, however, if there are any discrepancies, the records of the Company shall prevail. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Registered Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this Section 1(a), following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof. The Exercise Price may be paid by certified check or wire transfer.

b. Call (Redemption) Provisions. Notwithstanding anything to the contrary contained in this Warrant, this Warrant is callable (redeemable) at the Company’s option at any time, provided the closing price of the Common Stock is $0.36 (adjusted to reflect forward or reverse stock splits, recapitalizations, reorganizations or the like) or greater for five (5) consecutive Trading Days on the Trading Market (the “Call Condition”). Commencing at any time after the date on which the Call Condition is satisfied, the Company shall have the right, upon notice to the Registered Holder (the “Redemption Notice”), to redeem the number of Warrant Shares specified in the applicable Call Condition at a price of $0.01 per Warrant Share (the “Redemption Price”), on the date set forth in the Redemption Notice, but in no event earlier than sixty-one (61) days following the date of the receipt by the Registered Holder of the Redemption Notice (the “Redemption Date”). The Registered Holder may exercise this Warrant at any time (in whole or in part) prior to the Redemption Date at the Exercise Price. Any portion of this Warrant that is subject to the applicable Call Condition which is not exercised by the Redemption Date shall no longer be exercisable and shall be returned to the Company (and, if not so returned, shall automatically be deemed canceled), and the Company, upon its receipt of the unexercised portion of this Warrant, shall issue therefore in full and complete satisfaction of its obligations under such called but unexercised portion of this Warrant to the Registered Holder an amount equal to the number of shares of Common Stock called but remaining unexercised multiplied by the Redemption Price. The Redemption Price shall be mailed to such Registered Holder at its address of record, and the Warrant shall be canceled.

c. Mechanics of Exercise.

i. Delivery of Warrant Shares upon Exercise. Warrant Shares purchased hereunder shall be transmitted by the Company or its transfer agent to the Registered Holder in the Notice of Exercise within a commercially reasonable time, pursuant to SEC regulations, with the goal of accomplishing such action within three (3) Trading Days after delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been issued, and the Registered Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price and all taxes required to be paid by the Registered Holder, if any, having been paid and collected.

ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of the Registered Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Registered Holder a new Warrant evidencing the rights of the Registered Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Registered Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

iv. Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Registered Holder for any issue or transfer tax or other incidental expense in respect of the issuance of Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Registered Holder or in such name or names as may be directed by the Registered Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Registered Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Registered Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all transfer agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares as applicable.

2

v. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

2. Adjustments.

a. Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 2(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re classification.

b. Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions for which shareholder approval is required, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Registered Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Registered Holder, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction. For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Registered Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.

3

c. Calculations. All calculations under this Section 2 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 2, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

d. Notice to Registered Holder.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 2, the Company shall promptly mail to the Registered Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Registered Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the Registered Holder at its last address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K, provided that the requirement in this sentence shall only apply if any of the Company’s securities are listed or quoted for public trading. The Registered Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein

3. Transfers.

a. Unregistered Security. Each Registered Holder acknowledges that this Warrant and the Warrant Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and agrees not to sell, pledge, distribute, offer for sale, transfer, or otherwise dispose of this Warrant or any Warrant Shares issued upon its exercise in the absence of (i) an effective registration statement under the Securities Act as to this Warrant or such Warrant Shares and registration or qualification of this Warrant or such Warrant Shares under any applicable U.S. federal or state securities law then in effect or (ii) at the cost of the Registered Holder of this Warrant, an opinion of counsel, satisfactory to the Company, that such registration and qualification are not required. The Registered Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws. It is estimated that there will be at least a six month minimum holding period before any resales may be made of the Warrant Shares in the public market, however depending on the circumstances from time to time. Each certificate or other instrument for Warrant Shares issued upon the exercise of this Warrant shall bear a legend substantially to the foregoing effect.

The Registered Xxxxxx agrees that the Warrant Shares upon issuance may be notated with the following legend or legend of similar import: “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.” The Registered Holder agrees that in conformity with the Securities Purchase Agreement any other relevant legends may be affixed to the certificates or notations representing the Warrant Shares as applicable thereto.

4. No Impairment. The Company will not, by amendment of its charter or through reorganization, consolidation, merger, dissolution, sale of assets, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Registered Holder against impairment.

5. Termination. This Warrant (and the right to purchase securities upon exercise hereof) shall terminate on the Expiration Date.

6. Reservation of Stock. The Company will reserve and use reasonable commercial efforts to keep available, solely for the issuance and delivery upon the exercise of this Warrant, the Warrant Shares and other stock, securities, and property, as from time to time shall be issuable upon the exercise of this Warrant

7. Exchange of Warrants. Upon the surrender by the Registered Holder of this Warrant, properly endorsed, to the Company at the principal office of the Company, the Company will, subject to the provisions of Section 3 hereof, issue and deliver to or upon the order of such Registered Holder, at the Company’s expense, a new Warrant or Warrants of like tenor, in the name of such Registered Holder or as such Registered Holder (upon payment by such Registered Holder of any applicable transfer taxes) may direct, calling in the aggregate on the face or faces thereof for the number of Warrant Shares called for on the face or faces of the Warrant or Warrants so surrendered.

8. Replacement of Warrants. Upon 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) upon delivery of an indemnity agreement (with surety if reasonably required) in an amount reasonably satisfactory to the Company, or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will issue, in lieu thereof, a new Warrant of like tenor.

9. Miscellaneous.

a. No Rights as Stockholder. Until the exercise of this Warrant, the Registered Holder of this Warrant shall not have or exercise any rights by virtue hereof as a stockholder of the Company.

b. Amendment or Waiver. Any term of this Warrant may be amended or waived upon written consent of the Company and the Registered Holder.

f. Severability. If one or more provisions of this Warrant are held to be unenforceable under applicable law, such provision shall be excluded from this Warrant, the balance of this Warrant shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms.

g. Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party under this Warrant, upon any breach or default of any other party under this Warrant, shall impair any such right, power, or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent, or approval of any kind or character on the part of any party of any breach or default under this Warrant, or any waiver on the part of any party of any provisions or conditions of this Warrant, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Warrant or by law or otherwise afforded to any party, shall be cumulative and not alternative. If the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Registered Holder, the Company shall pay to the Registered Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Registered Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

i. Representation by Registered Holder. The Registered Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

j. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

6

k. Authorized Shares. The Company covenants that, during the period this Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be traded. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

l. Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Registered Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Registered Holder, shall give rise to any liability of the Registered Holder for the Exercise Price of any Warrant Shares or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

m. Remedies. The Registered Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.
