COMMON
STOCK PURCHASE OPTION


 


PHARMALECTIN,
INC.


 


Option
Shares: 4,500,000





Date
of Issuance: June 4, 2021 (“Issuance Date”)


 


This
COMMON STOCK PURCHASE OPTION (the “Option”) certifies that NDPD Pharma, Inc., a Delaware corporation (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 Pharmalectin,
Inc., a Delaware corporation (the “Company”), a subsidiary of Bioxytran, Inc., a Nevada Corporation (the “Parent
Company”) up to 4,500,000 shares of Common Stock (as defined below) (the “Option Shares”) (whereby such
number may be adjusted from time to time pursuant to the terms and conditions of this Option) at the Exercise Price per share
then in effect. This Option is issued by the Company as of the date hereof in connection with the Company’s 2017 Stock Plan.


 


Capitalized
terms used in this Option shall have the meanings set forth in the Purchase Agreement unless otherwise defined in the body of
this Option or in Section 12 below. For purposes of this Option, the term “Exercise Price” shall mean $0.33
(Thirty-three cents), 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 Issuance Date and ending on 5:00 p.m. eastern standard
time on the five-year anniversary thereof.


 


1.             EXERCISE
OF OPTION.


 


(a)       Mechanics
of Exercise. Subject to the terms and conditions hereof, the rights represented by this Option 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 Option. The Holder shall not
be required to deliver the original Option in order to affect an exercise hereunder. Partial exercises of this Option resulting
in purchases of a portion of the total number of Option Shares available hereunder shall have the effect of lowering the outstanding
number of Option Shares purchasable hereunder in an amount equal to the applicable number of Option Shares purchased. On or before
the second Trading Day (the “Option Share Delivery Date”) following the date on which the Holder sent the Exercise
Notice to the Company or the Company’s transfer agent, 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 Option Shares as to which all or a portion of this Option 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, 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 (or deliver such shares of Common Stock in electronic format if requested by the Holder). 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 Option Shares
with respect to which this Option has been exercised, irrespective of the date of delivery of the certificates evidencing such
Option Shares. If this Option is submitted in connection with any exercise and the number of Option Shares represented by this
Option submitted for exercise is greater than the number of Option 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 Option
(in accordance with Section 6) representing the right to purchase the number of Option Shares purchasable immediately prior to
such exercise under this Option, less the number of Option Shares with respect to which this Option 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
Option 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 Debenture.


 


If
the Market Price of one share of the Parent Company’s Common Stock is greater than the Exercise Price, the Holder may elect
to receive Option Shares pursuant to a cashless exercise, in lieu of a cash exercise, equal to the value of this Option determined
in the manner described below (or of any portion thereof remaining unexercised) by surrender of this Option 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 Option Shares that the Holder elects to purchase under this Option





(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 Option as a consequence of any adjustment
pursuant hereto. All Option Shares (including fractions) issuable upon exercise of this Option 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 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 Option Share by such fraction.


 


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


 


 (a)       Distribution
of Assets. If the Parent 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 Option, 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






    


     


    




(ii)       the
number of Option 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 Option to purchase Other Shares of Common Stock in lieu of an increase in the number of
Option Shares, the terms of which shall be identical to those of this Option, except that such Option 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 Option 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 Option was decreased with respect to the Distribution pursuant to the terms
of the immediately preceding clause (i) and the number of Option Shares calculated in accordance with the first part of this clause
(ii).


 


(b)       Anti-Dilution
Adjustments to Exercise Price. If the Parent Company or any Subsidiary thereof, as applicable, at any time while this
Option is outstanding, shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise
dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or
securities entitling any person or entity to acquire shares of Common Stock (upon conversion, exercise or otherwise)
(including but not limited to under the Note), at an effective price per share less than the then Exercise Price (such lower
price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”)
(if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase
price adjustments, elimination of an applicable floor price for any reason in the future (including but not limited to the
passage of time or satisfaction of certain condition(s)), reset provisions, floating conversion, exercise or exchange prices
or otherwise, or due to Options, options or rights per share which are issued in connection with such issuance, be entitled
or potentially entitled to receive shares of Common Stock at an effective price per share which is less than the Exercise
Price at any time while such Common Stock or Common Stock Equivalents are in existence, such issuance shall be deemed to have
occurred for less than the Exercise Price on such date of the Dilutive Issuance (regardless of whether the Common Stock or
Common Stock Equivalents are (i) subsequently redeemed or retired by the Parent Company after the date of the Dilutive
Issuance or (ii) actually converted or exercised at such Base Share Price), then the Exercise Price shall be reduced at the
option of the Holder and only reduced to equal the Base Share Price, and the number of Option Shares issuable hereunder shall
be increased such that the aggregate Exercise Price payable hereunder, after taking into account the decrease in the Exercise
Price, shall be equal to the aggregate Exercise Price prior to such adjustment (for the avoidance of doubt, the aggregate
Exercise Price prior to such adjustment is calculated as follows: the total number of Option Shares multiplied by the initial
Exercise Price in effect as of the Issuance Date). Such adjustment shall be made whenever such Common Stock or Common Stock
Equivalents are issued, regardless of whether the Common Stock or Common Stock Equivalents are (i) subsequently redeemed or
retired by the Parent Company after the date of the Dilutive Issuance or (ii) actually converted or exercised at such Base
Share Price by the holder thereof (for the avoidance of doubt, the Holder may utilize the Base Share Price even if the Parent
Company did not actually issue shares of its common stock at the Base Share Price under the respective Common
stock Equivalents). The Parent Company shall notify the Holder in writing, no later than the Trading Day following the
issuance of any Common Stock or Common Stock Equivalents subject to this Section 2(b), indicating therein the applicable
issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice the
“Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive
Issuance Notice pursuant to this Section 2(b), upon the occurrence of any Dilutive Issuance, after the date of such Dilutive
Issuance the Holder is entitled to receive a number of Option Shares based upon the Base Share Price regardless of whether
the Holder accurately refers to the Base Share Price in the Notice of Exercise.


 


(c)       Subdivision
or Combination of Common Stock. If the Parent Company at any time on or after the Issuance Date subdivides (by any stock split,
stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number
of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of
Option Shares will be proportionately increased. If the Parent Company at any time on or after the Issuance Date combines (by
combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number
of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number
of Option Shares will be proportionately decreased. Any adjustment under this Section 2(c) shall become effective at the close
of business on the date the subdivision or combination becomes effective. Each such adjustment of the Exercise Price shall be
calculated to the nearest one-hundredth of a cent. Such adjustment shall be made successively whenever any event covered by this
Section 2(c) shall occur.






    


     


    




3.             FUNDAMENTAL
TRANSACTIONS. If, at any time while this Option is outstanding, (i) the Company, or the Parent Company, effects any merger
of the Company, or the Parent Company, with or into another entity and the Company, or the Parent Company, is not the surviving
entity (such surviving entity, the “Successor Entity”), (ii) the Company, or the Parent 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 the Parent Company, or by another individual or entity, and approved by the Company, or the
Parent 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, or the Parent 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 Option, 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 Option 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 Option 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 Option consistent with
the foregoing provisions and evidencing the Holder’s right to exercise such Option 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 Option, and
will at all times in good faith carry out all the provisions of this Option 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 Option 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 Option, and (iii) shall, for so long as this Option is
outstanding, have authorized and reserved, free from preemptive rights, ten (10) times the number of shares of Common Stock
into which the Options are then exercisable into to provide for the exercise of the rights represented by this Option
(without regard to any limitations on exercise).


 


5.             OPTION
HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, this Option, 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
Option shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Option or
otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.


 


6.              REISSUANCE.


 


(a)       Lost,
Stolen or Mutilated Option. If this Option 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 Option, include the surrender thereof),
issue a new Option of like denomination and tenor as this Option so lost, stolen, mutilated or destroyed.


 


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






    


     


    




7.            TRANSFER.
This Option shall be binding upon the Company and its successors and assigns, and shall inure to be the benefit of the Holder
and its successors and assigns. Notwithstanding anything to the contrary herein, the rights, interests or obligations of the Company
hereunder may not be assigned, by operation of law or otherwise, in whole or in part, by the Company without the prior signed
written consent of the Holder, which consent may be withheld at the sole discretion of the Holder (any such assignment or transfer
shall be null and void if the Company does not obtain the prior signed written consent of the Holder). This Option or any of the
severable rights and obligations inuring to the benefit of or to be performed by Holder hereunder may be assigned by Holder to
a third party, in whole or in part, without the need to obtain the Company’s consent thereto.


 


8.              NOTICES.
Whenever notice is required to be given under this Option, 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 Option 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 AND VENUE. This Option shall be governed by and construed in accordance with the laws of the State of Nevada without regard
to principles of conflicts of laws. Any action brought by either party against the other concerning the transactions contemplated
by this Option shall be brought only in the state courts located in the State of Florida, County of Miami-Dade or federal courts
located in the State of Florida, County of Miami-Dade. The parties to this Option hereby irrevocably waive any objection to jurisdiction
and venue of any action instituted hereunder and shall not assert any defense based on lack of jurisdiction or venue or based
upon forum non conveniens. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A
JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS OPTION OR ANY TRANSACTION
CONTEMPLATED HEREBY. The prevailing party shall be entitled to recover from the other party its reasonable attorney’s fees
and costs. In the event that any provision of this Option or any other agreement delivered in connection herewith is invalid or
unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that
it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may
prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision of any agreement.
Each party hereby irrevocably waives personal service of process and consents to process being served in any suit, action or proceeding
in connection with this Agreement or any other Transaction Document by mailing a copy thereof via registered or certified mail
or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any other manner permitted by law.
