THIS WARRANT CERTIFIES THAT, for good
and valuable consideration, NENTER & CO., INC. (together with any registered holder from time to time of this Warrant
or any holder of the shares issuable or issued upon exercise of this Warrant, “Holder”) is entitled to purchase
the number of fully paid and nonassessable shares of the class of securities of the Company at the Warrant Price, all as set forth
above and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth
in this Warrant.


 


ARTICLE
1 EXERCISE.


 


1.1.           
Exercise. This Warrant shall be exercisable for 10,000,000 shares of the Company’s Common Stock
(the “Shares”) at the Warrant Price set forth above. The number of Shares and the Warrant Price are subject
to adjustment as provided herein, and all references to “Shares” and “Warrant Price” herein shall be deemed
to include any such adjustment or series of adjustments.


 


1.2.           
Method of Exercise.


 






     


     

    

(a)              
Mechanics. This Warrant may be exercised by the Holder at any time on or after the Issue Date (an “Exercise
Date”), in whole or in part, by delivery (whether via facsimile or otherwise) of a written notice, in the form attached
hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within
one (1) Trading Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Company of an amount
equal to the Warrant Price in effect on the date of such exercise multiplied by the number of Shares as to which this Warrant was
so exercised (the “Aggregate Warrant Price”) in cash or via wire transfer of immediately available funds if
the Holder did not notify the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined
in Article 1.3). The Holder shall not be required to deliver the original of this Warrant in order to effect an exercise hereunder.
Execution and delivery of an Exercise Notice with respect to less than all of the Shares shall have the same effect as cancellation
of the original of this Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Shares.
Execution and delivery of an Exercise Notice for all of the then-remaining Shares shall have the same effect as cancellation of
the original of this Warrant after delivery of the Shares in accordance with the terms hereof. On or before the later of the third
(3rd) Trading Day following the date on which the Company has received such Exercise Notice and one (1) Trading Day after the Company’s
receipt of the Aggregate Exercise Warrant Price (or valid notice of a Cashless Exercise) (such later date, the “Share
Delivery Deadline”), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust
Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate
number of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s
balance account with DTC through its Deposit/Withdrawal at Custodian system, or (Y) if the Transfer Agent is not participating
in the DTC Fast Automated Securities Transfer Program, upon the request of the Holder, issue and deliver (via reputable overnight
courier) to the address as specified in the Exercise 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 pursuant to such exercise. Upon delivery of an Exercise
Notice, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Shares with respect to
which this Warrant has been exercised, irrespective of the date such Shares are credited to the Holder’s DTC account or the
date of delivery of the certificates evidencing such Shares (as the case may be). If this Warrant is submitted in connection with
any exercise pursuant to this Article 1 and the number of Shares represented by this Warrant submitted for exercise is greater
than the number of Shares being acquired upon an exercise and upon surrender of this Warrant to the Company by the Holder, then,
at the request of the Holder, the Company shall as soon as practicable and in no event later than three (3) Business Days after
any exercise and at its own expense, issue and deliver to the Holder (or its designee) a new Warrant representing the right to
purchase the number of Shares purchasable immediately prior to such exercise under this Warrant, less the number of Shares with
respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant,
but rather the number of shares of Common Stock to be issued shall be rounded down to the nearest whole number. The Company shall
pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation, fees and expenses
of the Transfer Agent) that may be payable with respect to the issuance and delivery of Shares upon exercise of this Warrant. Notwithstanding
the foregoing, the Company’s failure to deliver Shares to the Holder on or prior to the Share Delivery Deadline shall not
be deemed to be a breach of this Warrant.


 






    	2



     

    

(b)              
Company’s Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for
no reason, on or prior to the Share Delivery Deadline, if the Transfer Agent is not participating in the DTC Fast Automated Securities
Transfer Program, to issue and deliver to the Holder (or its designee) a certificate for the number of Shares to which the Holder
is entitled and register such Shares on the Company’s share register or, if the Transfer Agent is participating in the DTC
Fast Automated Securities Transfer Program, to credit the balance account of the Holder or the Holder’s designee with DTC
for such number of Shares to which the Holder is entitled upon the Holder’s exercise of this Warrant (as the case may be),
and if on or after such Share Delivery Deadline the Holder purchases (in an open market transaction or otherwise) shares of Common
Stock to deliver in satisfaction of a sale by the Holder of all or any portion of the number of shares of Common Stock issuable
upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”), then, in addition to
all other remedies available to the Holder, the Company shall, within three (3) Business Days after the Holder’s request
and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase
price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including,
without limitation, by any other Person in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which
point the Company’s obligation to so issue and deliver such certificate (and to issue such shares of Common Stock) or credit
the balance account of such Holder or such Holder’s designee, as applicable, with DTC for the number of Shares to which the
Holder is entitled upon the Holder’s exercise hereunder (as the case may be) (and to issue such Shares) shall terminate and
the applicable Exercise Notice shall be disregarded as if never submitted by the Holder, or (ii) promptly honor its obligation
to so issue and deliver to the Holder a certificate or certificates representing such Shares or credit the balance account of such
Holder or such Holder’s designee, as applicable, with DTC for the number of Shares to which the Holder is entitled upon the
Holder’s exercise hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of
the Buy-In Price over the product of (A) such number of Shares multiplied by (B) the average closing price of the Common Stock
across all Trading Days during the period commencing on the date of the applicable Exercise Notice and ending on the date of such
issuance and payment under this clause (ii). Nothing shall limit the Holder’s right to pursue any other remedies available
to it hereunder, at law or in equity, including, without limitation, a decree of specific performance and/or injunctive relief
with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock (or to electronically
deliver such shares of Common Stock) upon the exercise of this Warrant as required pursuant to the terms hereof.


 


1.3.           
Cashless Exercise Right. In lieu of exercising this Warrant by making the cash payment otherwise contemplated
to be made to the Company upon such exercise in payment of the Aggregate Warrant Price pursuant to Article 1.2,
Holder may elect instead to receive upon such exercise the “Net Number” of shares
of Common Stock determined according to the following formula (a “Cashless Exercise”):


 





	 	Net Number = (A x B) - (A x C)


                                               B
	 
	 		 



 















    	3



     

    

For purposes of the foregoing formula:


 


A = the total number of shares with respect to which this Warrant
is then being exercised.


 


B = the fair market value of each Share,
which shall be (i) the average for the five Trading Days immediately prior to the date of determination thereof of the last reported
sale price regular way on each such day, or (ii) in the case no such sale takes place on any such day, the average of the reported
closing bid and asked prices regular way of the shares of Common Stock on such day, in each case as quoted on the Principal Market,
as reported by Bloomberg or such other principal securities exchange or inter-dealer quotation system on which the shares of Common
Stock are then traded, or (iii) in the case the shares of Common Stock are not traded publically on the Principal Market, the value
mutually agreed up by the Company and the Holder.


 


C= the Warrant Price then in effect for the applicable Shares at the time
of such exercise.


 


1.4.           
Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant, and,
if applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for
the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing
the Shares not so acquired. Holder shall be deemed to own and have all of the rights associated with any Shares or other securities
or property to which it is entitled pursuant to this Warrant upon the exercise or conversion of the Warrant in accordance with
this Article 1.


 


1.5.           
Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and in the case of loss, theft or destruction, on delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of mutilation on surrender and cancellation of this Warrant,
the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.


 


1.6.           
Treatment of Warrant Upon Acquisition of Company.


 


1.6.1       
“Acquisition”. For the purpose of this Warrant, “Acquisition” shall mean the occurrence
of any of the following: (i) the consolidation of the Company with, or the merger of the Company with or into, another “person”
(as such term is used in Rule 13d-3 and Rule 13d-5 of the Exchange Act), or the sale, lease, transfer, conveyance or other disposition,
in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries taken
as a whole, or the consolidation of another “person” with, or the merger of another “person” into, the
Company, other than in each case pursuant to a transaction in which the “persons” that “beneficially owned”
(as such term is defined in Rule 13d-3 and Rule 13d-5 under the Exchange Act), directly or indirectly, the Voting Shares (as defined
below) of the Company immediately prior to the transaction “beneficially own”, directly or indirectly, Voting Shares
representing at least a majority of the total voting power of all outstanding classes of voting stock of the surviving or transferee
person; (ii) the adoption by the Company of a plan relating to the liquidation or dissolution of the Company; (iii) the
consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person”
becomes the “beneficial owner” directly or indirectly, of more than 50% of the Voting Shares of the Company (measured
by voting power rather than number of shares); or (iv) the first day on which a majority of the members of the Company’s
Board of Directors (the “Board”) does not consist of Continuing Directors (as defined below). For the purposes of this
Article 1.6.1, (i) “Voting Shares” of any person shall mean capital shares or capital stock of such person which ordinarily
has voting power for the election of directors (or persons performing similar functions) of such person, whether at all times or
only so long as no senior class of securities has such voting power by reason of any contingency, and (ii) “Continuing Director”
shall mean, as of any date of determination, any member of the Board who (i) was a member of the Board on the Issue Date or (ii)
was nominated for election or elected to the Board with the approval of a majority of the Continuing Directors who were members
of the Board at the time of such nomination or election and who voted with respect to such nomination or election; provided that
a majority of the members of the Board voting with respect thereto shall at the time have been Continuing Directors.


 






    	4



     

    




1.6.2       
Treatment of Warrant at Acquisition. In the event of an Acquisition, either (a) Holder shall exercise
or convert his Warrant in full with respect to all remaining Shares for which the Warrant is then exercisable and such exercise
or conversion will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to
exercise or convert the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide
Holder with written notice of the foregoing (together with such reasonable information as Holder may request in connection with
such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior
to the closing of the proposed Acquisition.


 


1.7.           
Insufficient Authorized Shares. If at any time while the Warrant remains outstanding the Company does
not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance
upon exercise of the Warrant at least a number of shares of Common Stock equal to 100% (the “Required Reserve Amount”)
of the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of the Warrant then outstanding,
then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock
to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Warrant then outstanding.


 


ARTICLE
2 ADJUSTMENTS TO THE SHARES.


 


2.1.           
Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the Shares payable in common
stock of the Company, or other securities, then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without
cost to Holder, the total number and kind of shares of common stock of the Company to which Holder would have been entitled had
Holder owned the Shares of record as of the date the dividend occurred. If the Company subdivides the Shares by reclassification
or otherwise into a greater number of shares or takes any other action which increases the amount of stock for which this Warrant
is exercisable, the number of Shares subject to the Warrant shall be proportionately increased and the Warrant Price shall be proportionately
decreased. If the outstanding shares are combined or consolidated, by reclassification or otherwise, into a lesser number of shares,
the Warrant Price shall be proportionately increased and the number of Shares subject to the Warrant shall be proportionately decreased.


 






    	5



     

    

2.2.           
Reclassification, Exchange, Combinations or Substitution. Upon any reclassification, 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 (other than an Acquisition which is subject to the provisions of Article 1.6), 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 the Shares
if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. The Company
or its successor shall promptly issue to Holder an amendment to this Warrant setting forth the number and kind of such new securities
or other property issuable upon exercise or conversion of this Warrant as a result of such reclassification, exchange, substitution
or other event that results in a change of the number and/or class of securities issuable upon exercise or conversion of this Warrant.
The amendment to this 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 Warrant Price and to the number of securities
or property issuable upon exercise of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications,
exchanges, substitutions, or other events.


 


2.3.           
Rights Upon 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 (which dividend or other distribution has
not already been given to the Holder of the Warrant), 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, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance
of this Warrant and prior to the Expiration Date, then, in each such case:


 


(a)              
any Warrant 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 Warrant Price by a fraction of which (i) the numerator shall
be the Closing Bid 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 shall be the Closing Bid Price of the shares of Common Stock on the Trading Day immediately preceding
such record date; and


 


(b)              
the number of 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 paragraph
(a);


 






    	6



     

    




provided that in the event that the Distribution is of shares of
Common Stock(“Other Shares of Common Stock”) of a company whose common shares are traded on a national securities exchange
or a national automated quotation system, 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 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
warrant price equal to the product of the amount by which the warrant price of this Warrant was decreased with respect to the Distribution
pursuant to the terms of the immediately preceding paragraph (a) and the number of Shares calculated in accordance with the first
part of this paragraph (b).


 









2.4.           
Other Adjustment Events. If any event occurs of the type contemplated by the provisions of this Article
2 but not expressly provided for by such provisions, then the Company’s Board of Directors will make an appropriate adjustment
in the Warrant Price and the number of Warrant Shares so as to protect the rights of the Holder; provided that no such adjustment
pursuant to this Article 2.4 will increase the Warrant Price or decrease the number of Shares as otherwise determined pursuant
to this Article 2.


 


2.5.           
No Impairment. Without the consent of the Holder, the Company shall not by amendment of its 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 the 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.


 


2.6.           
Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion of this 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, the Company shall eliminate such fractional share interest by paying Holder in cash
equivalent to the amount computed by multiplying the fractional interest by the fair market value of a full Share (as determined
pursuant to Article 1.3 of this Warrant).


 


2.7.           
Certificate as to Adjustments. Upon each adjustment of the Warrant Price and Shares, the Company shall
promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with
a certificate of its Chief Financial Officer, Corporate Secretary or a senior financial officer setting forth such adjustment and
the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth
the Warrant Price and Shares in effect upon the date thereof and the series of adjustments leading to such Warrant Price and Shares.

ARTICLE
3 REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.


 


3.1.           
Representations and Warranties. The Company represents and warrants and covenants to the Holder as follows:
all Shares which may be issued upon the exercise of the purchase right represented by this Warrant shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens and encumbrances except for restrictions on transfer
provided for herein or under applicable federal and state securities laws. The Company will at all times reserve and keep available,
out of its authorized but unissued share of Common Stock, solely for the purpose of providing the exercise or conversion of this
Warrant, the aggregate number of Shares issuable upon exercise or conversion of this Warrant. The Company will use its reasonable
best efforts to ensure that the Shares may be issued without violation of any law or regulation applicable to the Company or of
any requirement of any securities exchange applicable to the Company on which the Shares are listed or traded.


 


3.2.           
No Stockholder Rights. Except as provided in this Warrant, and other than with regard to shares of the
Company’s Common Stock acquired by Holder other than pursuant to the exercise of this Warrant, the Holder will not have any
rights as a stockholder of the Company until the exercise of this Warrant.


 


3.3.           
Charges, Taxes and Expenses. Issuance of certificates for Shares to the Holder or the credit of the Shares
to the Holder or the Holder’s designee with DTC upon the exercise or conversion of this Warrant shall be made without charge
to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificates, all of
which taxes and expenses shall be paid by the Company.


 


3.4.           
Removal of Restrictive Legends. Upon the expiration of any applicable holding period pursuant to Rule
144 promulgated under the Securities Act for the Shares issuable upon exercise of this Warrant, the Company agrees, at its sole
cost and expense to cause its legal counsel to issue an opinion letter in favor of the Company’s transfer agent instructing
the transfer agent to remove any restrictive legend on the Shares restricting the transfer of such Shares.


 


3.5.       Share
Registration. On Holder’s request, the Company agrees to use best efforts to cause the Shares issued upon exercise of
the Warrant to be registered under the Securities Act of 1933 (the “Securities Act”) within 90 days of exercise of
the Warrant.


 





ARTICLE
4 REPRESENTATIONS AND WARRANTIES OF THE HOLDER. The Holder represents
and warrants to the Company as follows:


 


4.1.           
Purchase for Own Account. This Warrant and the securities to be acquired upon exercise or conversion of
this Warrant by the Holder will be acquired for investment for the Holders account, not as a nominee or agent, and not with a view
to the public resale or distribution within the meaning of the Securities Act of 1933 (the “Securities Act”)
and the Holder has no present intention, and upon exercise or conversion will have no intention, of selling or engaging in any
public distribution of the same except pursuant to a registration or exemption. Holder also represents that the Holder has not
been formed for the specific purpose of acquiring this Warrant or the Shares.


 






    	8



     

    

4.2.           
Disclosure of Information. The Holder has received or has had full access to all the information it considers
necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying
securities. The Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms
and conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent
the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information
furnished to the Holder or to which the Holder has access.


 


4.3.           
Investment Experience. The Holder understands that the purchase of this Warrant and its underlying securities
involves substantial risk. The Holder has experience as an investor in securities of companies in the development stage and acknowledges
that the Holder can bear the economic risk of such Holder’s investment in this Warrant and its underlying securities and
has such knowledge and experience in financial or business matters that the Holder is capable of evaluating the merits and risks
of its investment in this Warrant and its underlying securities and/or has a preexisting personal or business relationship with
the Company and certain of its officers, directors or controlling persons of a nature and duration that enables the Holder to be
aware of the character, business acumen and financial circumstances of such persons.


 


4.4.           
Accredited Investor Status. The Holder is an “accredited investor” within the meaning of Regulation
D promulgated under the Securities Act.


 


4.5.           
The Securities Act. The Holder understands that this Warrant and the Shares issuable upon exercise or
conversion hereof have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein. The Holder
understands that this Warrant and the Shares issued upon any exercise or conversion hereof must be held indefinitely unless subsequently
registered under the Securities Act and qualified under applicable state securities laws, or unless exemption from such registration
and qualification are otherwise available. The Holder further understands that settlement of this Warrant is to be made in Shares
and, for the elimination of doubt, the fact that the Shares delivered on exercise of this Warrant will not be registered under
the Securities Act (as defined below) will not in any way require the Company to settle this Warrant otherwise than in Shares,
including without limitation, that there is no circumstance that would require the Company to settle this Warrant in cash.

5 MISCELLANEOUS.

5.2.           
Legends. This Warrant and the Shares shall be imprinted with a legend in substantially the following form:

BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL TO THE HOLDER (IF REQUESTED BY THE COMPANY), IN A FORM

Warrant may not be transferred or assigned in whole or in part without compliance with applicable federal and state securities
laws by the transferor and the transferee (including, without limitation, the delivery of investment representation letters and
legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder
to provide an opinion of counsel if the transfer is to any affiliate of the Holder, provided that any such transferee is an “accredited

agree to be bound by the terms of this Warrant as if an original holder hereof.
