1.4
Limitations on Exercise. The Company shall not, and shall not instruct the Transfer Agent to, effect any exercise of any
Warrant, and a registered holder shall not have the right to exercise any portion of a Warrant, to the extent that after giving
effect to the issuance of shares of Common Stock after exercise as set forth on the applicable Election to Purchase, the registered
holder (together with such registered holder’s Affiliates (as defined in Rule 405 under the Securities Act of 1933), and
any other persons acting as a group together with the registered holder or any of the registered holder’s Affiliates), would
beneficially own in excess of 4.99% of the Company’s Common Stock. For purposes of the foregoing sentence, the number of
shares of Common Stock beneficially owned by the registered holder and its Affiliates shall include the number of shares of Common
Stock issuable upon exercise of the 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 exercise of the remaining, non-exercised portion of any Warrant beneficially
owned by the registered holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this Section
6, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder, it being acknowledged by the registered holder that neither the Warrant Agent nor the Company is representing
to the registered holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the registered holder
is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained
in this Section 6 applies, the determination of whether a Warrant is exercisable (in relation to other securities owned by the
registered holder together with any Affiliates) and of which portion of a Warrant is exercisable shall be in the sole discretion
of the registered holder, and the submission of an Election to Purchase shall be deemed to be the registered holder’s determination
of whether such Warrant is exercisable (in relation to other securities owned by the registered holder together with any Affiliates)
and of which portion of a Warrant is exercisable, and neither the Warrant Agent nor the Company shall have any obligation to verify
or confirm the accuracy of such determination and neither of them shall have any liability for any error made by the registered
holder. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 6, in determining
the number of outstanding shares of Common Stock, a registered 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 Securities and Exchange 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
the Company’s transfer agent setting forth the number of shares of Common Stock outstanding. The provisions of this Section
6 shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 6 to correct
this subsection (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation
herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations
contained in this paragraph shall apply to a successor holder of a Warrant.

 

ARTICLE
2 ADJUSTMENTS.

 

2.1
Stock Dividends. Splits. Etc. If Company declares or pays a dividend on its common stock (or Shares if Shares are securities
other than common stock) payable in common stock or other securities, subdivides the outstanding common stock into a greater amount
of common stock, or, if Shares are securities other than common stock, subdivides Shares in a transaction that increases the amount
of common stock into which Shares are convertible, then upon exercise of this Warrant, for each Share acquired, Holder shall receive,
without cost to Holder, the total number and kind of securities to which Holder would have been entitled had Holder owned Shares
of record as of the date the dividend or subdivision occurred.

 

    	2

    	 

    

 

2.2
Reclassification. Recapitalization. Exchange or Substitution. Upon any reclassification, recapitalization, exchange, substitution,
or other event that results in a change of the number and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of this Warrant, the number and kind of securities and
property that Holder would have received for Shares if this Warrant had been exercised immediately before such reclassification,
recapitalization, exchange, substitution, or other event. Company or its successor shall promptly issue to Holder a new Warrant
for such new securities or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the Exercise
Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, recapitalizations, exchanges, substitutions, or other events.

 

2.3
Adjustments for Combinations. Etc. If the outstanding Shares are combined or consolidated, by reclassification or otherwise,
into a lesser number of shares, the Exercise Price shall be proportionately increased and the number of Shares as to which this
warrant is exercisable shall be proportionately decreased.

 

2.4
Adjustment for Pay-to-Pay Transactions. in the event that the Company’s Articles (Certificate) of Incorporation provides,
or is amended to so provide, for the amendment or modification of the rights, preferences or privileges of the Shares, or the
reclassification, conversion or exchange of the outstanding shares of the Class of Stock, in the event that a holder of shares
thereof fails to participate in an equity financing transaction (a “Pay-to-Play Provision”), and in the event that
such Pay-to-Play Provision becomes operative in a transaction occurring after the date hereof, this Warrant shall automatically
and without any action required become exercisable for that number and type of shares of equity securities as would have been
issued or exchanged, or would have remained outstanding, in respect of the Shares issuable hereunder had this Warrant been exercised
in full prior to such event, and had the Holder participated in the equity financing to the maximum extent permitted.

 

2.5
No Impairment. Company shall not, by amendment of its Articles/Certificate of Incorporation or through a reorganization,
transfer of assets, consolidation, merger, 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 to be observed or performed under this Warrant by Company, but shall
at all times in good faith assist in carrying out of all the provisions of this Article 2 and in taking all such action as may
be necessary or appropriate to protect Holder’s rights under this Article against impairment. If Company takes any dilutive
action affecting Shares or its common stock other than as described above that adversely affects Holder’s rights under this
Warrant, the Exercise Price shall be adjusted downward and the number of Shares issuable upon exercise of this Warrant shall be
adjusted upward in such a manner that such dilutive action is offset and the aggregate Exercise Price of this Warrant is unchanged.

 

2.6
Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion of the Warrant and the number of
Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise
or conversion of the Warrant, Company shall eliminate such fractional share interest by paying Holder an amount computed by multiplying
the fractional interest by the fair market value of a full Share.

 

2.7
Certificate as to Adjustments. Upon each adjustment of the Exercise Price, Company at its expense shall promptly compute
such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts
upon which such adjustment is based. Company shall, upon written request, furnish Holder a certificate setting forth the Exercise
Price in effect upon the date thereof and the series of adjustments leading to such Exercise Price.

COMMENCING JANUARY 1, 2018

 

THIS
CERTIFIES THAT, in consideration of good and valuable consideration, based on the exercise of A, B, and C Warrants of EnzymeBioSystems
____________________ (“Holder”) is entitled, at any time or from time-to-time at or after January 1, 2018 (“Exercise
Date”), and at or before 5:00 p.m., Eastern Time on August 31, 2022 (“Expiration Date”) but not thereafter,
to subscribe for, purchase and receive, in whole or in part, _________________ shares of Common Stock of the Company, par value
$0.001 per share, at an exercise price subject to Section 3(d) (the “Warrant Exercise Price”).

 

This
Warrant is subject to the following provisions, terms and conditions:

 

1.
The Cashless Warrant extends for the life of the Warrant until its Expiration Date. The rights represented by this Cashless Warrant,
may be exercised by Holder, in whole or in part, by written notice of exercise substantially in the form attached hereto delivered
to the Company at least ten (10) days prior to the intended date of exercise and by the surrender of this Warrant (properly endorsed
if required) at the principal office of the Company, together with payment of the exercise price by any of the following means,
or a combination thereof, at the election of the holder:

 

(i)
cash, certified check or cashier’s check or wire transfer; or

 

(ii)
surrender of the Warrant at the principal office or the Company together with holder’s notice of election, in which event
the Company shall immediately issue the holder the number of shares of Common Stock computed using the following formula:

 

    	 	 	 

     

    

 

X
= Y (A-B)/A

 

Where:

 

X
= the number of’ shares of Common stock to be issued to the holder (not to exceed the number of shares set forth on the
cover page of this Warrant, as adjusted pursuant to the provisions of Section 3 of this Warrant Agreement).

 

Y
= the number of shares of Common Stock for which the Warrant is being exercised.

 

A
= the Market Price” of one share of common Stock (for purposes of this Section), shall be defined as the closing price of
the common Stock on the business day immediately prior to the date of exercise of this Warrant (the “Closing Bid Price”),
as reported by the National Association of Securities Dealers Automated Quotation system (“NASDAQ”), or if the Common
Stock is not traded on NASDAQ, the closing Bid Price in the OTC-BB market; provided, however, that if the Common Stock is listed
on a stock exchange, the Market Price shall be the closing Bid Price on such exchange; and, provided further, that if the Common
Stock is not quoted or listed by any organization, the fair value of the Common Stock, as reasonably determined by the Board of
Directors of the Company, whose determination shall be conclusive, shall be used).

 

B
= the Exercise Price of $0.40 share.

 

The
shares of Common Stock purchased shall be deemed to be issued to the holder hereof as the record owner of such shares of: Common
Stock as of the earliest date allowed by applicable Federal securities laws. The Company shall deliver to the holder, as promptly
as practicable, certificates representing the shares being purchased; and, in case of exercise hereof in part only, the Company
upon surrender hereof, will deliver to the holder a new Warrant certificate or Warrant Certificates of like tenor entitling the
holder to purchase the number of shares as to which this Warrant has not been exercised.

 

2.
The Company covenants and agrees that all Warrant Shares that may be issued upon the exercise of the rights represented by this
warrant shall, upon issuance, be duly authorized and issued, fully paid and nonassessable shares. The Company further covenants
and agrees that during the period within which the rights represented by this warrant may be exercised, the Company will at all
times have authorized, and reserved for the purpose of issue or transfer upon exercise of the subscription rights evidenced by
this warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this
warrant.

 

3.
The Warrant Exercise Price and number of Warrant Shares shall be adjusted as provided in this Section 3.

 

(a)
If the Company shall pay a dividend in shares of its Common Shares, subdivide (split) its outstanding shares of Common Stock,
combine (reverse split) its outstanding shares of Common Stock, issue by reclassification of its shares of Common Stock any shares
or other securities of the Company, or distribute to holders of its Common Stock any securities of the Company or of another entity,
the number of shares of Common Stock or other securities the Holder hereof is entitled to purchase pursuant to this Warrant immediately
prior thereto shall be adjusted so that the Holder shall be entitled to receive upon exercise the number of shares of Common Stock
or other securities which he or she would have owned or would have been entitled to receive after the happening of any of the
events described above had this Warrant been exercised immediately prior to the happening of such event, and the exercise price
per share shall be correspondingly adjusted.. An adjustment made pursuant to this Section shall become effective immediately after
the record date in the case of the stock dividend or other distribution and shall become effective immediately after the effective
date in the case of a subdivision, combination or reclassification.

 

    	 

    	 

    

 

(b)
If any capital reorganization or reclassification of the capital stock of the Company, or consolidation or merger of the Company
with another corporation, or the sale of all or substantially all of its assets to another corporation shall be effected in such
a way that holders of the Company’s Common Stock shall be entitled to receive stock, securities or assets with respect to
or in exchange for such shares, then, as a condition of such reorganization, reclassification, consolidation, merger or sale,
Holder shall have the right to purchase and receive upon the basis and upon the terms and conditions specified in this warrant
and in lieu of the shares of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise
of the rights represented hereby, such shares of stock, other securities or assets as would have been issued or delivered to Holder
if it had exercised this warrant and had received such shares of Common Stock prior to such reorganization, reclassification,
consolidation, merger or sale. The Company shall not effect any such consolidation, merger or sale, unless prior to the consummation
thereof the successor corporation (if other than the Company) resulting from such consolidation or merger or the corporation purchasing
such assets shall assume by written instrument executed and mailed to Holder at the last address of Holder appearing on the books
of the Company, the obligation to deliver to Holder such shares of stock, securities or assets as, in accordance with the foregoing
provisions, Holder may be entitled to purchase.

 

(c)
Upon adjustment of the Warrant Exercise Price, Holder shall thereafter be entitled to purchase, at the Warrant Exercise Price,
the number of shares obtained by multiplying the Warrant Exercise Price in effect immediately prior to such adjustment by the
number of shares purchasable pursuant hereto immediately prior to such adjustment and dividing the product thereof by the Warrant
Exercise Price resulting from such adjustment.

 

(d)
Warrant Exercise Price can be adjusted upwards or downwards, subject to the mutual agreement of the Board of Directors and Warrant
holder(s), at any time prior to the life of the Warrant.

 

4.
This Warrant shall not entitle Holder to any voting rights or other rights as a shareholder of the Company.

 

Limitations
on Exercise. The Company shall not, and shall not instruct the Transfer Agent to, effect any exercise of any Warrant, and
a registered holder shall not have the right to exercise any portion of a Warrant, to the extent that after giving effect to the
issuance of shares of Common Stock after exercise as set forth on the applicable Election to Purchase, the registered holder (together
with such registered holder’s Affiliates (as defined in Rule 405 under the Securities Act of 1933), and any other persons
acting as a group together with the registered holder or any of the registered holder’s Affiliates), would beneficially
own in excess of 4.99% of the Company’s Common Stock. For purposes of the foregoing sentence, the number of shares of Common
Stock beneficially owned by the registered holder and its Affiliates shall include the number of shares of Common Stock issuable
upon exercise of the 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 exercise of the remaining, non-exercised portion of any Warrant beneficially owned by
the registered holder or any of its Affiliates.

 

    	 

    	 

    

 

5.
Holder, by acceptance hereof, agrees to give written notice to the Company before transferring this warrant or transferring any
Warrant Shares of Holder’s intention to do so, prior to the exercise date, describing briefly the manner of any proposed
transfer of this warrant or such Warrant Shares. Promptly upon receiving such written notice, the Company shall present copies
thereof to counsel for the Company. If, in the opinion of such counsel, the proposed transfer of this warrant or disposition of
Warrant Shares may be effected without registration or qualification (under any federal or state law) of this warrant or the Warrant
Shares, the Company, as promptly as practicable, shall notify Holder of such opinion, whereupon Holder shall be entitled to transfer
this warrant or such Warrant Shares, all in accordance with the terms of the notice delivered by Holder to the Company, provided
that an appropriate legend in substantially the form set forth at the end of this warrant respecting the foregoing restrictions
on transfer and disposition may be endorsed on this warrant or the certificates for such Warrant Shares. At or after the exercise
date, the Holder may transfer the Warrant Shares without the approval of the Company. At that time, the Company will transfer
to Warrant Shares to the Holder’s assigned transferee.

 

6.
Restrictions Imposed by the Securities Act. This Warrant and the Securities underlying this Warrant shall not be transferred unless
and until (i) the Company has received the opinion of counsel for the Holder that such securities may be transferred pursuant
to an exemption from registration under the Act, and applicable state law, the availability of which is established to the reasonable
satisfaction of the Company, or (ii) a registration statement relating to such Securities has been filed by the Company and declared
effective by the Securities and Exchange Commission (“SEC”) and compliance with applicable state law. Provided that
the Warrant holder has an opinion of counsel or a registration statement has been declared effective with the SEC, this warrant
and all rights hereunder are transferable, in whole or in part, at the principal office of the Company by Holder in person or
by duly authorized attorney, upon surrender of this warrant properly endorsed to any person or entity who represents in writing
that he/it is acquiring the warrant for investment and without any view to the sale or other distribution thereof. Holder, by
taking or holding this warrant, consents and agrees that the bearer of this warrant, when endorsed, may be treated by the Company
and all other persons dealing with this warrant as the absolute owner hereof for any purpose and as the person entitled to exercise
the rights represented by this warrant, or to the transfer hereof on the books of the Company, any notice to the contrary notwithstanding;
but until such transfer on such books, the Company may treat the registered owner hereof as the owner for all purposes.

 

7.
Piggyback Registration. Holder has been granted piggyback registration rights with respect to the shares underlying this Warrant.
The terms “register,” “registered” and “registration” refer to a registration
effected by preparing and filing with the Securities and Exchange Commission (the “SEC”) a registration statement
pursuant to the Securities Act of 1933, as amended (the “Act”), and the declaration or order of effectiveness
of such registration statement, other than any registration statement on a Form S-8, Form S-4 or as contemplated under Rule 145
of the Act. For the purposes of this Section 7 the term “Registerable Securities” means any Warrant Securities
purchasable or purchased pursuant to this Warrant which have not been sold to the public.

 

(a)
The Warrant Holder shall, regardless of whether all or part of this Warrant has been exercised, have piggyback registration rights
to register his/her underlying shares/securities pursuant to the Securities Act of 1933 (the “Act”), as is necessary
on an applicable form of registration or the resale of all of the Registrable Securities. Upon completion of such registration(s)
the cashless warrant provisions, in Section 1 of this Warrant, shall become void, but shall be voided only if and when all the
Securities underlying this Warrant are fully registered during the term of the Warrant which ends March 20, 2022. Any Registration
Statement prepared pursuant hereto shall register for resale all of the underlying Securities represented in this Warrant. Further,
the Company shall use its best efforts to have each Registration Statement declared effective by the SEC, as soon as practicable.

 

    	 

    	 

    

 

(b)
If the Company at any time proposes to register any of its securities under the Act, whether of its own accord or at the demand
of any holders of other such securities pursuant to an agreement with respect to the registration thereof (provided such agreement
does not prohibit third parties from including additional securities in such registration), and if the form of registration statement
proposed to be used may be used for the registration of Registerable Securities as contemplated hereunder, the Company will give
notice to Holder not less than 10 days nor more than 30 days prior to the filing of such registration statement of its intention
to proceed with the proposed registration (the “Registration”), and, upon written request of the Holder made
within ten (10) days after the receipt of any such notice (which request will specify the Registerable Securities intended to
be disposed of by the Holder and state the intended method of disposition thereof), the Company will use its best efforts to cause
all Registerable Securities of Holder as to which registration has been requested to be registered under the Act, provided that
if such Registration is in connection with an underwritten public offering, Holder’s Registerable Securities to be included
in such Registration shall be offered upon the same terms and conditions as apply to any other securities included in such Registration.
Notwithstanding anything contained in this Section 7 to the contrary, the Company shall have no obligation to cause Registerable
Securities to be registered with respect to any Registerable Securities which shall be eligible for resale under Rule 144 of the
Securities Act.

 

(c)
If a Registration is a primary registration on behalf of the Company and is in connection with an underwritten public offering,
and if the managing underwriters advise the Company in writing that in their opinion the amount of securities requested to be
included in such Registration (whether by the Company, the Holder, or other holders of the Company’s securities pursuant
to any other rights granted by the Company to participate in such Registration) exceeds the amount of such securities which can
be successfully sold in such offering, the Company will include in such Registration the amount of securities requested to be
included which in the opinion of such underwriters can be sold, in the following order (A) first, all of the securities the Company
proposes to sell, and (B) second, any other securities held by holders with registration rights requested to be included in such
Registration, pro rata among the holders thereof on the basis of the amount of such securities then owned by such holders.

 

(d)
If a Registration is a secondary registration on behalf of holders of securities of the Company and is in connection with an underwritten
public offering, and if the managing underwriters advise the Company in writing that in their opinion the amount of securities
requested to be included in such Registration (whether by such holders, by the Holder, or by holders of the Company’s securities
pursuant to any other rights granted by the Company to participate in such Registration) exceeds the amount of such securities
which can be sold in such offering, the Company will include in such Registration the amount of securities requested to be included
which in the opinion of such underwriters can be sold, in the following order (A) first, all of the securities requested to be
included by holders with demand registration rights who are demanding such Registration, pro rata among the holders thereof on
the basis of the amount of such securities then owned by such holders, and (B) second, any other securities held by holders with
piggyback registration rights, requested to be included in such Registration, pro rata among the holders thereof on the basis
of the amount of such securities then owned by such holders.

 

8.
Neither this Warrant nor any term hereof may be changed, waived, discharged or terminated orally but only by an instrument in
writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought.

 

9.
Stock to be Delivered upon Exercise. The Company will at all times keep available through the term of the Exercise Period, solely
for delivery upon the exercise of this Warrant, such number of the shares of Common Stock or other securities as shall from time
to time be sufficient to effect the exercise of this Warrant.

 

    	 

    	 

    

 

10.
Replacement of Warrant. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation
of this Warrant and, in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement reasonably satisfactory
in form and amount to the Company or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the
Company will execute and deliver, in lieu thereof, a new warrant of like tenor to Holder.

 

11.
Specific Performance. The Company stipulates that the remedies at law available to the holder of this Warrant in the event of
any default or threatened default by it in the performance of or compliance with any of the terms of the Agreement are not and
will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

 

12.
Applicable Law. THIS WARRANT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEVADA, WITHOUT
GIVING EFFECT TO PRINCIPLES OF CHOICE OF LAWS OF SUCH STATE.

 

13.
Entire Agreement. This Warrant constitutes the entire agreement between the parties with respect to the subject matter hereof
and supersedes any and all prior agreements and understandings relating to the subject matter hereof. This Warrant and any of
the terms hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against
which enforcement of such change, waiver, discharge or termination is sought.

 

14.
Severability. Every provision of this Warrant is intended to be severable. If any term or provision hereof (or portion thereof)
is determined to be illegal or unenforceable for any reason whatsoever, such illegality or unenforceability shall not affect any
other term or provision (or portion thereof) of this Warrant.
