COMMON STOCK PURCHASE WARRANT


PREDICTIVE ONCOLOGY INC.


 


Warrant Shares: 92,700


Date of Issuance: April 5, 2020 (the “Issuance
Date”)


 


THIS COMMON STOCK PURCHASE
WARRANT (the “Warrant”) certifies that, for value received (in connection with the funding of that certain senior
secured convertible promissory note dated February 5, 2020, in the original principal amount of up to $1,450,000.00 by the Company
(as defined below) to the Lender (as defined below)) (the “Note”), Oasis Capital, LLC, a Puerto Rico limited
liability company (the “Lender” and 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 during
the Exercise Period, to purchase from Predictive Oncology, Inc., a Delaware corporation (the “Company”), up
to 92,700 shares of Common Stock (as defined below) (the “Warrant Shares”) at the Exercise Price per share then
in effect. The number of Warrant Shares for which this Warrant may be exercised is subject to adjustment in accordance with the
terms hereof. This Warrant is issued by the Company as of the date hereof pursuant to the securities purchase agreement dated February
5, 2020, between the Company and the Lender (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 14 below. For purposes of this Warrant, the term “Exercise Price” shall mean $2.992 per
share, subject to adjustment as provided herein (including but not limited to cashless exercise), and the term “Exercise
Period” shall mean the period commencing on the date that is six months after the Issuance Date and ending on 5:00 p.m.
eastern standard time on the five-year anniversary of such date. 


 


1.       EXERCISE
OF WARRANT.


 


(a)       Mechanics
of Exercise. Subject to the terms and conditions hereof, the rights represented by this Warrant may be exercised in whole or
in part at any time or times during the Exercise Period by delivery of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. The Holder shall not
be required to deliver the original Warrant in order to effect an exercise hereunder. 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. On or before
the second Trading Day (the “Warrant Share Delivery Date”) following the date on which the Company shall have
received the Exercise Notice, which Exercise Notice must be received by the Company prior to 11 a.m., New York, New York time to
count as received on such date, and upon receipt by the Company of payment to the Company of an amount equal to the applicable
Exercise Price multiplied by the number of Warrant Shares as to which all or a portion of this Warrant is being exercised (the
“Aggregate Exercise Price” and together with the Exercise Notice, the “Exercise Delivery Documents”)
in cash or by wire transfer of immediately available funds (or by cashless exercise if permitted under the terms of this Warrant,
in which case there shall be no Aggregate Exercise Price provided), the Company shall (or direct its transfer agent to) issue and
dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise. Upon delivery of the Exercise Delivery Documents, the Holder shall be deemed for all corporate purposes
to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of
the date of delivery of the certificates evidencing such Warrant Shares. If this Warrant is submitted in connection with any exercise
and the number of Warrant Shares represented by this Warrant is greater than the number of Warrant Shares being acquired upon an
exercise, then the Company shall as soon as practicable and in no event later than three business days after any exercise and at
its own expense, issue a new Warrant (in accordance with Section 6) representing the right to purchase the number of Warrant
Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which
this Warrant is exercised.


 






     

     


    

If the Company fails to
cause its transfer agent to transmit to the Holder the respective shares of Common Stock by the respective Warrant Share Delivery
Date, then the Holder will have the right to rescind such exercise in Holder’s sole discretion, and such failure shall be
deemed an “Event of Default” under the Note. Without in any way limiting the Holder’s right to pursue other remedies,
including actual damages and/or equitable relief, the parties agree that if delivery of the Common Stock issuable upon conversion
of this Warrant is not delivered by the Warrant Share Delivery Date the Company shall pay to the Holder $3,000 per day, for each
day beyond the Warrant Share Delivery Date that the Company fails to deliver such Common Stock (unless such failure results from
war, acts of terrorism, an epidemic, or natural disaster). Such amount shall be paid to Holder in cash by the fifth day of the
month following the month in which it has accrued. The Company agrees that the right to exercise is a valuable right to the Holder.
The damages resulting from a failure, attempt to frustrate, interference with such exercise right are difficult if not impossible
to qualify. Accordingly, the parties acknowledge that the liquidated damages provision contained in this Section 1(a) are
justified.


 


If, at any time during
the Exercise Period, there is no effective registration statement of the Company covering the Holder’s immediate resale of
the Warrant Shares without any limitations, then the Holder may elect to receive Warrant Shares pursuant to a cashless exercise,
in lieu of a cash exercise, equal to the value of this Warrant determined in the manner described below (or of any portion thereof
remaining unexercised) by surrender of this Warrant and a Notice of Exercise, in which event the Company shall issue to Holder
a number of Common Stock computed using the following formula:


 


X = Y (A-B)


A


 


	Where  	X =	the number of shares to be issued to Holder.
	 	 	 
	 	Y =	the number of Warrant Shares that the Holder elects to purchase under this Warrant (at the date of such calculation).
	 	 	 
	 	A =	the Market Price (at the date of such calculation).
	 	 	 
	 	B =	Exercise Price (as adjusted to the date of such calculation).


 


(b)       No
Fractional Shares. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment
pursuant hereto. 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, pay to the Holder
otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then-current fair market
value of a Warrant Share by such fraction.


 






    	 	2	 



     


    

(c)       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 (as such term is defined under the Exchange
Act), 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 (c), 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 Section 1(c),
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 Commission, as the case may
be, (B) a more 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.


 


2.       ADJUSTMENTS.
The Exercise Price and the number of Warrant Shares shall be adjusted from time to time as follows:


 


(a)       Distribution
of Assets. If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its
assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including without limitation any distribution
of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement
or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each
such case:


 


(i)       any
Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of
shares of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close of business on such record
date, to a price determined by multiplying such Exercise Price by a fraction (i) the numerator of which shall be the Closing Sale
Price of the shares of Common Stock on the Trading Day immediately preceding such record date minus the value of the Distribution
(as determined in good faith by the Company’s Board of Directors) applicable to one share of Common Stock, and (ii) the denominator
of which shall be the Closing Sale Price of the shares of Common Stock on the Trading Day immediately preceding such record date;
and


 






    	 	3	 



     


    

(ii)       the
number of Warrant Shares shall be increased to a number of shares equal to the number of shares of Common Stock obtainable immediately
prior to the close of business on the record date fixed for the determination of holders of shares of Common Stock entitled to
receive the Distribution multiplied by the reciprocal of the fraction set forth in the immediately preceding clause (i); provided,
however, that in the event that the Distribution is of shares of common stock of a company (other than the Company) whose common
stock is traded on a national securities exchange or a national automated quotation system (“Other Shares of Common Stock”),
then the Holder may elect to receive a warrant to purchase Other Shares of Common Stock in lieu of an increase in the number of
Warrant Shares, the terms of which shall be identical to those of this Warrant, except that such warrant shall be exercisable into
the number of shares of Other Shares of Common Stock that would have been payable to the Holder pursuant to the Distribution had
the Holder exercised this Warrant immediately prior to such record date and with an aggregate exercise price equal to the product
of the amount by which the exercise price of this Warrant was decreased with respect to the Distribution pursuant to the terms
of the immediately preceding clause (i) and the number of Warrant Shares calculated in accordance with the first part of this clause
(ii).


 


3.       FUNDAMENTAL
TRANSACTIONS. If, at any time while this Warrant is outstanding, (i) the Company effects any merger of the Company with or
into another entity and the Company is not the surviving entity (such surviving entity, the “Successor Entity”),
(ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) any
tender offer or exchange offer (whether by the Company or by another individual or entity, and approved by the Company) is completed
pursuant to which holders of Common Stock are permitted to tender or exchange their shares of Common Stock for other securities,
cash or property and the holders of at least 50% of the Common Stock accept such offer, or (iv) the Company effects any reclassification
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 (other than as a result of a subdivision or combination of shares of Common Stock) (in any
such case, a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall
have the right to receive the number of shares of Common Stock of the Successor Entity or of the Company and any additional consideration
(the “Alternate Consideration”) receivable upon or as a result of such reorganization, reclassification, merger,
consolidation or disposition of assets by a holder of the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event (disregarding any limitation on exercise contained herein solely for the purpose of such determination).
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 Holder shall be given the same choice
as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. To the
extent necessary to effectuate the foregoing provisions, any Successor Entity in such Fundamental Transaction shall issue to the
Holder a new warrant consistent with the foregoing provisions and evidencing the Holder’s right to exercise such warrant
into Alternate Consideration.


 


4.       NON-CIRCUMVENTION.
The Company covenants and agrees that it will not, by amendment of its certificate of incorporation, bylaws or through any reorganization,
transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other 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, three times the number of shares of Common Stock issuable under the Warrant, or as otherwise required
under the Purchase Agreement, to provide for the exercise of the rights represented by this Warrant (without regard to any limitations
on exercise).


  


5.       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.


 






    	 	4	 



     


    

6.       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. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant
shall be of like tenor with this Warrant, and shall have an issuance date, as indicated on the face of such new Warrant which is
the same as the Issuance Date.


 


7.       TRANSFER.


 


(a)       Notice
of Transfer. The Holder agrees to give written notice to the Company before transferring this Warrant or transferring any Warrant
Shares of such Holder’s intention to do so, describing briefly the manner of any proposed transfer. 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 B
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 7 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.


 


(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).


 


8.       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
(i) immediately upon any adjustment of the Exercise Price, setting forth in reasonable detail, the calculation of such adjustment
and (ii) at least 20 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.


 


9.       AMENDMENT
AND WAIVER. The terms of this Warrant may be amended or waived (either generally or in a particular instance and either retroactively
or prospectively) only with the written consent of the Company and the Holder.


  


10.       Governing
Law. This Warrant shall be governed by and interpreted in accordance with the laws of the State of New York without regard
to the principles of conflicts of law (whether of the State of New York or any other jurisdiction).


 






    	 	5	 



     


    

11.       Arbitration.
Any disputes, claims, or controversies arising out of or relating to this Warrant, or the transactions, contemplated thereby, or
the breach, termination, enforcement, interpretation, or validity thereof, including the determination of the scope or applicability
of this Warrant to arbitrate, shall be referred to and resolved solely and exclusively by binding arbitration to be conducted before
the Judicial Arbitration and Mediation Service (“JAMS”), or its successor pursuant the expedited procedures
set forth in the JAMS Comprehensive Arbitration Rules and Procedures (the “Rules”), including Rules 16.1 and
16.2 of those Rules. The arbitration shall be held in New York, New York, before a tribunal consisting of three (3) arbitrators
each of whom will be selected in accordance with the “strike and rank” methodology set forth in Rule 15. Either party
to this Warrant may, without waiving any remedy under this Warrant, seek from any federal or state court sitting in the State of
New York any interim or provisional relief that is necessary to protect the rights or property of that party, pending the establishment
of the arbitral tribunal. The costs and expenses of such arbitration shall be paid by and be the sole responsibility of the Company,
including but not limited to the Holder’s attorneys’ fees and each arbitrator’s fees. The arbitrators’
decision must set forth a reasoned basis for any award of damages or finding of liability. The arbitrators’ decision and
award will be made and delivered as soon as reasonably possible and in any case within sixty (60) days’ following the conclusion
of the arbitration hearing and shall be final and binding on the parties and may be entered by any court having jurisdiction thereof.


 


12.       JURY
TRIAL WAIVER. THE COMPANY AND THE HOLDER HEREBY WAIVE A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY
EITHER OF THE PARTIES HERETO AGAINST THE OTHER IN RESPECT OF ANY MATTER ARISING OUT OF OR IN CONNECTION WITH THIS WARRANT.

dividend, stock split, stock combination or other similar transaction during the applicable calculation period.
