FOR VALUE RECEIVED, GB SCIENCES, INC., a Nevada corporation (the “Company”) with its principal executive office at 3550 W. Teco Avenue, Las Vegas NV 89118, promises to pay to the order of CSW VENTURES, LP (the “Payee” or the “Holder of this Note”) or registered assigns, the principal amount of One Million Five Hundred Thousand Dollars ($1,500,000) Dollars, or such lesser amount as shall equal the aggregate unpaid principal amount of the loans made by Payee to the Company hereunder (the “Principal Amount”), together with interest on such Principal Amount, on August 28, 2020 (the “Maturity Date”).   Interest on this Senior Secured Convertible Promissory Note (this “Note”) shall accrue on the Principal Amount outstanding from time to time at a rate per annum computed in accordance with Section 2 hereof.

This Note represents an initial loan of One Million Dollars made on the Issue Date.  Subject to the terms and conditions of the Note Purchase Agreement (defined below), an additional loan or loans under this Note in the aggregate amount of Five Hundred Thousand Dollars are to be made within 10 business days of the Issue Date.  The date each such loan is made shall be endorsed by Payee on its books, and, prior to any transfer of this Note, endorsed by Payee on the schedule attached hereto or any continuation thereof.  Any failure by Payee to so endorse shall in no way mitigate or discharge the obligation of the Company to repay any loan actually made.

Interest shall accrue on the Principal Amount outstanding from time to time commencing on the date hereof and shall be payable (i) quarterly in arrears commencing on April 1, 2019 and on the first day of each calendar quarter thereafter, (ii) upon maturity (whether at the Maturity Date, by acceleration or otherwise) and (iii) at any time after maturity until paid in full (after as

Active\89265696.v2

well as before judgment), on demand.  All computations of interest hereunder shall be made based on the actual number of days elapsed in a year of 365 days (including the first day but excluding the last day during which any such Principal Amount is outstanding).  All payments by the Company hereunder shall be applied first to pay any interest which is due, but unpaid, and then to reduce the Principal Amount.

Each payment by the Company pursuant to this Note shall be made without set-off or counterclaim and in immediately available funds by wire or check only.  THIS NOTE MAY NOT BE PAID OR PREPAID IN CASH.  The Company (i) waives presentment, demand, protest or notice of any kind in connection with this Note and (ii) agrees to pay to the Holder of this Note, on demand, all costs and expenses (including reasonable and documented legal fees and expenses) incurred in connection with the enforcement and collection of this Note.

This Note has been issued to Payee pursuant to a Note Purchase Agreement (the “Note Purchase Agreement”) entered into between the Company and the Payee dated as of the date hereof, and is secured by a Security Agreement dated as of the date hereof (the “Security Agreement”) among the Company, GB Sciences Nevada LLC (“GBSN”), GB Sciences Las Vegas LLC (“GBSLV”) and Payee, covering certain collateral (the “Collateral”), all as more particularly described and provided therein, and is entitled to the benefits thereof.  The Security Agreement and any and all other documents executed and delivered by the Company, GBSN or GBSLV (the “Grantors”) to Payee under which Payee is granted liens on assets of the Grantors in connection with the transactions contemplated by the Note Purchase Agreement are collectively referred to as the “Security Documents.”

Unless otherwise defined in this Note, capitalized terms used herein shall have the meanings set forth in the Note Purchase Agreement.

1.Principal Repayment 

A.Optional Prepayment.  Subject to 1B below, the Company may only prepay this Note,  

(i)during such time as the Conversion Shares (as defined below) issuable upon conversion of this Note are then subject to an effective registration statement under the Securities Act of 1933, as amended, and the registration statement covering the Conversion Shares has been effective for a period of at least 90 days; or 

(ii)if the Company provides the Payee with sixty (60) days prior written notice of such prepayment, during which time Payee may convert this Note in accordance with Section 5, and such prepayment is accompanied by a payment equal to 25% of the amount of the principal and interest being prepaid. 

B.Notice of Prepayment.  Before the Company shall be permitted to prepay this Note pursuant to 1A(i) hereof, the Company shall provide thirty (30) days prior notice to the  

2

Active\89265696.v2

Payee of its intent to make such prepayment, which notice shall state the date and amount of such prepayment (the “Prepayment Date”).  The Payee shall have the option at any time prior to the Prepayment Date to elect to convert this Note pursuant to Section 5 below.

2.Computation of Interest. 

A.Base Interest Rate.  Subject to Sections 2B and 2C below, the outstanding Principal Amount shall bear interest at the rate of eight (8%) percent per annum.  

B.Penalty Interest.  Upon the occurrence and during the continuance of an Event of Default (as defined below), the rate of interest applicable to the unpaid Principal Amount shall be increased to ten (10%) percent per annum. 

C.Maximum Rate.  In the event that it is determined that, under the laws relating to usury applicable to the Company or the indebtedness evidenced by this Note (“Applicable Usury Laws”), the interest charges and fees payable by the Company in connection herewith or in connection with any other document or instrument executed and delivered in connection herewith cause the effective interest rate applicable to the indebtedness evidenced by this Note to exceed the maximum rate allowed by law (the “Maximum Rate”), then such interest shall be recalculated for the period in question and any excess over the Maximum Rate paid with respect to such period shall be credited, without further agreement or notice, to the Principal Amount outstanding hereunder to reduce said balance by such amount with the same force and effect as though the Company had specifically designated such extra sums to be so applied to principal and the Payee had agreed to accept such extra payment(s) as a premium-free prepayment. All such deemed prepayments shall be applied to the principal balance payable at maturity. In no event shall any agreed-to or actual exaction as consideration for this Note exceed the limits imposed or provided by Applicable Usury Laws in the jurisdiction in which the Company is resident applicable to the use or detention of money or to forbearance in seeking its collection in the jurisdiction in which the Company is resident.

8

Active\89265696.v2

addition to every other remedy conferred herein or now or hereinafter existing at law or in equity or by statute or otherwise.

5.Conversion of Note. 

A.Optional Conversion.  The Holder of this Note shall have the option, at any time and from time to time, prior to the date on which the Company makes payment in full of the Principal Amount of this Note in accordance herewith, all accrued interest thereon and all other amounts due and payable thereunder to convert all or any portion of the outstanding Principal Amount of this Note plus all accrued and unpaid interest thereon (such Principal Amount and accrued and unpaid interest to be so converted the “Conversion Amount”) into shares of common stock, par value $.0001 per share (“Common Stock”), of the Company at an initial conversion price per share equal to $0.17 per share (the “Conversion Price”), subject to adjustment as provided in subsection 5F below.  The shares of Common Stock issuable upon conversion of this Note at the Conversion Price are referred to herein as the “Conversion Shares.” 

B.Conversion Limitation.  Notwithstanding anything contained herein to the contrary, the Holder shall not be entitled to convert pursuant to the terms of this Note an amount that would be convertible into that number of Conversion Shares which would exceed the difference between the number of shares of Common Stock beneficially owned by such Holder and 4.99% of the outstanding shares of Common Stock of the Company.  For the purposes of the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities and Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. The Holder may void the Conversion Share limitation described in this Section 5B upon 65 days prior notice to the Company or without any notice requirement upon an Event of Default. 

C.Mechanics of Conversion. 

(i)Before the Holder of this Note shall be entitled to convert this Note into shares of Common Stock pursuant to Section 5A, such holder shall give written notice to the Company in the form attached hereto as Annex A (“Conversion Notice”), at its principal corporate office, by email, facsimile or otherwise, of the election to convert the same and shall state therein the Conversion Amount and the name or names in which the certificate or certificates for shares of Common Stock are to be issued.  On or before the third (3rd) business day following the date of receipt of a Conversion Notice, the Company shall (A) if legends are not required to be placed on certificates of Common Stock pursuant to the then existing provisions of Rule 144 of the Securities Act of 1933 (“Rule 144”) and provided that the Company’s transfer agent is participating in the Depository Trust Company's (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of shares of Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC, or (B) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion  

9

Active\89265696.v2

Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled which certificates shall not bear any restrictive legends unless required pursuant the Rule 144.  

(ii)All Common Stock which may be issued upon conversion of the Note will, upon issuance, be duly issued, fully paid and non-assessable and free from all taxes, liens, and charges with respect to the issuance thereof. 

D.Authorized Shares.  At all times the Company shall have authorized and shall have reserved a sufficient number of shares of Common Stock to provide for the conversion of the Principal Amount outstanding under this Note at the then effective Conversion Price.  Without limiting the generality of the foregoing, if, at any time, the Conversion Price is decreased, the number of shares of Common Stock authorized and reserved for issuance upon the conversion of this Note shall be proportionately increased. 

E.Failure to Timely Deliver Shares.  If within five (5) business days after the Company’s receipt of the facsimile or email copy of a Conversion Notice, the Company shall fail to issue and deliver to the Holder the number of shares of Common Stock to which the Holder is entitled upon such Holder's conversion of this Note (a “Conversion Failure”), the Company shall pay to the Holder $3,000 per day until the Company issues and delivers a certificate to the Holder for the number of shares of Common Stock to which the Holder is entitled upon such Holder’s conversion of any portion of the Principal Amount of this Note.  If the Company fails to deliver shares in accordance with the timeframe stated in this Section, resulting in a Conversion Failure, the Holder, at any time prior to selling all of those shares, may rescind any portion, in whole or in part, of that particular Conversion Notice attributable to the unsold shares. 

F.Anti-Dilution Provisions.  The Conversion Price in effect at any time and the number and kind of securities issuable upon the conversion of this Note shall be subject to adjustment from time to time upon the happening of certain events as follows: 

(i)In case the Company shall hereafter (i) declare a dividend or make a distribution on its outstanding shares of Common Stock in shares of Common Stock, (ii) subdivide or reclassify its outstanding shares of Common Stock into a greater number of shares, or (iii) combine or reclassify its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect at the time of the record date for such dividend or distribution or of the effective date of such subdivision, combination or reclassification shall be adjusted so that it shall equal the price determined by multiplying the Conversion Price by a fraction, the denominator of which shall be the number of shares of Common Stock outstanding after giving effect to such action, and the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such action.  Such adjustment shall be made successively whenever any event listed above shall occur. 

10

Active\89265696.v2

(ii)Whenever the Conversion Price is adjusted pursuant to Subsection (i) above, the number of Conversion Shares issuable upon conversion of this Note shall simultaneously be adjusted by multiplying the number of Conversion Shares initially issuable upon conversion of this Note by the Conversion Price in effect on the date hereof and dividing the product so obtained by the Conversion Price, as adjusted. 

(iii)In case of any reorganization, reclassification or change of the Common Stock (including any such reorganization, reclassification or change in connection with a consolidation or merger in which the Company is the continuing entity), or any consolidation of the Company with, or merger of the Company with or into, any other entity (other than a consolidation or merger in which the Company is the continuing entity), or of any sale of the properties and assets of the Company as, or substantially as, an entirety to any other person or entity, this Note shall thereafter be convertible into the kind and amount of stock or other securities or property receivable upon such reorganization, reclassification, change, consolidation, merger or sale by a Holder of the number of shares of Common Stock into which this Note would have been converted prior to such transaction.  The provisions of this subsection (iii) shall similarly apply to successive reorganizations, reclassifications, changes, consolidations, mergers or sales immediately prior to such reorganization, reclassification, change, consolidation, merger or sale. 

6.Amendments and Waivers. 

A.The provisions of this Note may from time to time be amended, modified or supplemented, if such amendment, modification or supplement is in writing and consented to by the Company and the Payee. 

B.No failure or delay on the part of the Payee in exercising any power or right under this Note shall operate as a waiver thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or the exercise of any other power or right.  No notice to or demand on the Company in any case shall entitle it to any notice or demand in similar or other circumstances.  No waiver or approval by the Payee shall, except as may be otherwise stated in such waiver or approval, be applicable to subsequent transactions.  No waiver or approval hereunder shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder. 

C.To the extent that the Company makes a payment or payments to the Payee, and such payment or payments or any part thereof are subsequently for any reason invalidated, set aside and/or required to be repaid by the Payee to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all rights and remedies therefor, shall be revived and continued in full force and effect as if such payment had not been made by the Payee or such enforcement or setoff had not occurred. 

11

Active\89265696.v2

7.Miscellaneous. 

A.Parties in Interest.  All covenants, agreements and undertakings in this Note binding upon the Company or the Payee shall bind and inure to the benefit of its successors and permitted assigns of the Company and the Payee, respectively, whether so express or not. 

B.Governing Law.  This Note shall be governed by and construed in accordance with the laws of the State of Nevada without regard to the conflicts of laws principles thereof.   

C.Waiver of Jury Trial.  THE PAYEE AND THE COMPANY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS NOTE OR ANY OTHER DOCUMENT OR INSTRUMENT EXECUTED AND DELIVERED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE PAYEE OR THE COMPANY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PAYEE’S PURCHASING THIS NOTE.
