hereunder are transferable, in whole or in part, on the books of the Company maintained for such purpose at the principal office

surrender of this Option properly endorsed and upon payment of any necessary transfer tax or other governmental charge imposed
upon such transfer. Upon any partial transfer, the Company shall issue and deliver to the Registered Holder a new Option or Options
with respect to the shares of Option Stock not so transferred. Each taker and holder of this Option, by taking or holding the same,
consents and agrees that this Option, when endorsed in blank, shall be deemed negotiable and that when this Option shall have been

5.          Adjustment
of Purchase Price, Number of Shares and Expiration Date. The number or character of shares of Option Stock issuable upon exercise
of this Option, the Purchase Price therefor and the Expiration Date shall be adjusted to the extent provided below upon occurrence
of the following events:

 

5.1           Adjustment
for Stock Splits, Stock Dividends, Recapitalization and Similar Events. The Purchase Price of this Option and the number of
shares of Option Stock issuable upon exercise of this Option shall each be proportionally adjusted to reflect any stock dividend,
stock split, combination of shares, reclassification, recapitalization or other similar event affecting the number of outstanding
shares of the Company's Stock. For example, if i); there should be a 2-for-1 stock split of the Company's Stock, the Purchase Price
of this Option shall be divided by two (2) and the number of shares of Option Stock purchasable under this Option shall be doubled,
if ii), there should be a 1-for-2 reverse stock split of the Company stock, the Purchase Price of this Option shall be multiplied
by two (2) and the number of shares of Option Stock purchasable under this Option shall be divided by two (2).

 

5.2.          Adjustment
for Other Dividends and Distributions. If the Company shall make or issue, or shall fix a record date for the determination
of eligible holders entitled to receive, a dividend or other distribution with respect to its Common Stock payable in securities
or other assets of the Company or any of its subsidiaries, then, and in each such case, the Registered Holder of this Option on
exercise of this Option at any time after the consummation, effective date or record date of such event, shall receive, in addition
to the shares of Option Stock issuable on such exercise prior to such date, the securities or such other assets to which such Registered
Holder would have been entitled upon such date if such Registered Holder had exercised this Option immediately prior thereto (all
subject to further adjustment as provided in this Option).

 

5.3           Liquidation;
Dissolution. If the Company shall dissolve, liquidate or wind up its affairs, the Registered Holder shall have the right, but
not the obligation, to exercise this Option effective as of the date of such dissolution, liquidation or winding up. If any such
dissolution, liquidation or winding up results in any cash distribution to the Registered Holder in excess of the portion of the
Purchase Price for the shares of Option Stock for which this Option is exercised, then the Registered Holder may, at its option,
exercise this Option without making payment of such portion of the Purchase Price and, in such case, the Company shall, upon distribution
to the Registered Holder, consider such portion of the Purchase Price to have been paid in full, and in making such settlement
to the Registered Holder, shall deduct an amount equal to such portion of the Purchase Price from the amount payable to the Registered
Holder.

 

    	3

    	 

    

 

6.          No
Impairment. The Company may not, by amendment of its Articles of Incorporation or Bylaws, or through reorganization, consolidation,
merger, dissolution, issue or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid
the observance or performance of any of the terms of this Option, but shall at all times in good faith assist in the carrying out
of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the
Registered Holder against impairment. Without limiting the generality of the foregoing, the Company (a) will not set nor increase
the par value (if any par value exists) of any shares of stock issuable upon the exercise of this Option above the amount payable
therefor upon such exercise, and (b) will take all such action as may be necessary or appropriate in order that the Company
may validly and legally issue fully paid and non-assessable shares of Option Stock upon the exercise of this Option.

 

7.          Certificate
as to Adjustments. In each case of any adjustment in either the Purchase Price or in the number of shares of Option Stock,
or other stock, securities or property receivable on the exercise of this Option, the Treasurer of the Company shall, upon written
request from Registered Holder, compute such adjustment in accordance with the terms of this Option and prepare a certificate setting
forth such adjustment and showing in detail the facts upon which such adjustment is based, including a statement of the adjusted
Purchase Price. The Company shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Registered
Holder.

 

8.          Notices
of Record Date. In case:

 

(a)          Of
any capital reorganization of the Company, any reclassification of the capital stock of the Company, any consolidation or merger
of the Company with or into another corporation, any initial public offering of the Company's Common Stock, or any conveyance of
all or substantially all of the assets of the Company to another entity in which holders of the Company's stock are to receive
stock, securities or property of another corporation; or

 

(b)          Of
any voluntary dissolution, liquidation or winding-up of the Company; then, and in each such case, the Company shall mail or
cause to be mailed to the Registered Holder of this Option a notice specifying, as the case may be, the date on which a
record is to be taken for the stated event at least ten (10) days prior to the effective or record date therein specified, as
applicable.

 

9.          Loss
or Mutilation. Upon Registered Holder’s delivery to the Company of evidence reasonably satisfactory to the Company of
the ownership, and the loss, theft, destruction or mutilation, of this Option, and of indemnity reasonably satisfactory to the
Company, and (in the case of mutilation) upon surrender and cancellation of this Option, the Company shall execute and deliver
to the Registered Holder in lieu thereof a new Option of like tenor.

 

    	4

    	 

    

 

10.         Reservation
of Option Stock. If at any time the number of authorized but unissued shares the Company's Common Stock or other securities
shall not be sufficient to effect the exercise of this Option, the Company shall take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of Common Stock or other securities to such number
of shares of Common Stock or other securities as shall be sufficient for such purpose.

 

11.         Sale
or Transfer of Option Stock. The Registered Holder of this Option, by acceptance hereof, agrees that the Registered
Holder will not make any disposition of all or any portion of this Option unless and until (i) there is then in effect a registration
statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement
or (ii) the Registered Holder shall have notified the Company of the proposed disposition and, if reasonably requested by the Company,
the Registered Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of the Option under the Act. The Company hereby agrees that the Company will not
require such an opinion of counsel for transactions made in accordance with Rule 144 promulgated under the Act except in unusual
circumstances. Notwithstanding the foregoing, no such registration statement or opinion of counsel shall be necessary for a transfer
of all or any portion of this Option or the Option Stock by a Registered Holder if the Registered Holder is a partnership or limited
liability company to a partner of such partnership or a retired partner of such partnership who retires after the date hereof,
or member of such limited liability company, as the case may be, or to the estate of any such partner, retired partner or member,
or the transfer by gift, will or intestate succession by any partner, retired partner or member to his or her spouse or to the
siblings, lineal descendants or ancestors of such partner, retired partner or member or his or her spouse, if the transferee agrees
in writing to be subject to the terms hereof to the same extent as if he or she were an original Registered Holder hereunder.

 

12.         General
Provisions.

 

12.1.  No
Rights or Liabilities as Shareholder. This Option does not by itself entitle the Registered Holder to any voting rights or
other rights as a shareholder of the Company. In the absence of affirmative action by Registered Holder to purchase Option Stock
by exercise of this Option, no provisions of this Option, and no enumeration herein of the rights or privileges of the Registered
Holder shall cause such Registered Holder to be a shareholder of the Company for any purpose by virtue hereof.

 

12.2.  Amendment. 
The provisions of this Option may be modified at any time by agreement of the parties. Any such agreement hereafter made shall
be ineffective to modify this Option in any respect unless in writing and signed by the parties against whom enforcement of the
modification or discharge is sought.

 

    	5

mailed by first class mail, (iii) one day after being sent by professional or overnight courier or messenger service guaranteeing
one-day delivery, or (iv) on the date of transmission if sent by telecopy or other means of electronic transmission resulting
in written copies, with receipt confirmed. Any such notice shall be delivered or addressed to the parties at the addresses set
forth below or at the most recent address specified by the addressee through written notice under this provision. Failure to conform
to the above requirements shall not defeat the effectiveness of notice actually received by the addressee.

 

12.4.  Change;
Waiver.  Any of the terms or conditions of this Option may be waived at any time by the party entitled to the benefit
thereof, but no such waiver shall affect or impair the right of the waiving party to require observance, performance or satisfaction
either of that term or condition as it applies on a subsequent occasion or of any other term or condition.

 

12.5.  Headings. 
The headings in this Option are for purposes of convenience and reference only, and shall not be deemed to constitute a part hereof.

5.1           Adjustment
for Stock Splits, Stock Dividends, Recapitalization and Similar Events. The Purchase Price of this Warrant and the number of
shares of Warrant Stock issuable upon exercise of this Warrant shall each be proportionally adjusted to reflect any stock dividend,
stock split, combination of shares, reclassification, recapitalization or other similar event affecting the number of outstanding
shares of the Company's Stock. For example, if i); there should be a 2-for-1 stock split of the Company's Stock, the Purchase Price
of this Warrant shall be divided by two (2) and the number of shares of Warrant Stock purchasable under this Warrant shall be doubled,
if ii), there should be a 1 for 2 reverse stock split of the Company stock, the Purchase Price of this Warrant shall doubled and
the number of shares of Warrant Stock purchasable under this Warrant shall be divided by two (2).

 

5.2.          Adjustment
for Other Dividends and Distributions. If the Company shall make or issue, or shall fix a record date for the determination
of eligible holders entitled to receive, a dividend or other distribution with respect to its Common Stock payable in securities
or other assets of the Company or any of its subsidiaries, then, and in each such case, the Registered Holder of this Warrant on
exercise of this Warrant at any time after the consummation, effective date or record date of such event, shall receive, in addition
to the shares of Warrant Stock issuable on such exercise prior to such date, the securities or such other assets to which such
Registered Holder would have been entitled upon such date if such Registered Holder had exercised this Warrant immediately prior

Dissolution. If the Company shall dissolve, liquidate or wind up its affairs, the Registered Holder shall have the right, but

dissolution, liquidation or winding up results in any cash distribution to the Registered Holder in excess of the portion of the
Purchase Price for the shares of Warrant Stock for which this Warrant is exercised, then the Registered Holder may, at its Warrant,
exercise this Warrant without making payment of such portion of the Purchase Price and, in such case, the Company shall, upon distribution

to the Registered Holder, shall deduct an amount equal to such portion of the Purchase Price from the amount payable to the Registered
Holder.

 

    	3

    	 

    

 

6.          No
Impairment. The Company may not, by amendment of its Articles of Incorporation or Bylaws, or through reorganization, consolidation,
merger, dissolution, issue or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid
the observance or performance of any of the terms of this Warrant, but shall at all times in good faith assist in the carrying
out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of
the Registered Holder against impairment. Without limiting the generality of the foregoing, the Company (a) will not set nor
increase the par value (if any par value exists) of any shares of stock issuable upon the exercise of this Warrant above the amount
payable therefor upon such exercise, and (b) will take all such action as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and non-assessable shares of Warrant Stock upon the exercise of this Warrant.

 

7.          Certificate
as to Adjustments. In each case of any adjustment in either the Purchase Price or in the number of shares of Warrant Stock,
or other stock, securities or property receivable on the exercise of this Warrant, the Treasurer of the Company shall, upon written
request from Registered Holder, compute such adjustment in accordance with the terms of this Warrant and prepare a certificate
setting forth such adjustment and showing in detail the facts upon which such adjustment is based, including a statement of the
adjusted Purchase Price. The Company shall cause copies of such certificate to be mailed (by first class mail, postage prepaid)
to the Registered Holder.

 

8.          Notices
of Record Date. In case:

 

(a)          Of

of the Company with or into another corporation, any initial public offering of the Company's Common Stock, or any conveyance of
all or substantially all of the assets of the Company to another entity in which holders of the Company's stock are to receive
stock, securities or property of another corporation; or

 

(b)          Of
any voluntary dissolution, liquidation or winding-up of the Company;

then, and in each such case, the Company
shall mail or cause to be mailed to the Registered Holder of this Warrant a notice specifying, as the case may be, the date on
which a record is to be taken for the stated event at least ten (10) days prior to the effective or record date therein specified,
as applicable.

 

9.          Loss
or Mutilation. Upon Registered Holder’s delivery to the Company of evidence reasonably satisfactory to the Company of
the ownership, and the loss, theft, destruction or mutilation, of this Warrant, and of indemnity reasonably satisfactory to the
Company, and (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company shall execute and deliver
to the Registered Holder in lieu thereof a new Warrant of like tenor.

 

10.         Reservation
of Warrant Stock. If at any time the number of authorized but unissued shares the Company's Common Stock or other securities
shall not be sufficient to effect the exercise of this Warrant, the Company shall take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of Common Stock or other securities to such number
of shares of Common Stock or other securities as shall be sufficient for such purpose.

or Transfer of Warrant Stock. The Registered Holder of this Warrant, by acceptance hereof, agrees that the Registered
Holder will not make any disposition of all or any portion of this Warrant unless and until (i) there is then in effect a registration
statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement
or (ii) the Registered Holder shall have notified the Company of the proposed disposition and, if reasonably requested by the Company,
the Registered Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of the Warrant under the Act. The Company hereby agrees that the Company will not
require such an opinion of counsel for transactions made in accordance with Rule 144 promulgated under the Act except in unusual
circumstances. Notwithstanding the foregoing, no such registration statement or opinion of counsel shall be necessary for a transfer
of all or any portion of this Warrant or the Warrant Stock by a Registered Holder if the Registered Holder is a partnership or
limited liability company to a partner of such partnership or a retired partner of such partnership who retires after the date
hereof, or member of such limited liability company, as the case may be, or to the estate of any such partner, retired partner
or member, or the transfer by gift, will or intestate succession by any partner, retired partner or member to his or her spouse
or to the siblings, lineal descendants or ancestors of such partner, retired partner or member or his or her spouse, if the transferee
agrees in writing to be subject to the terms hereof to the same extent as if he or she were an original Registered Holder hereunder.

 

12.          General
Provisions.

 

12.1.  No
Rights or Liabilities as Shareholder. This Warrant does not by itself entitle the Registered Holder to any voting rights or
other rights as a shareholder of the Company. In the absence of affirmative action by Registered Holder to purchase Warrant Stock
by exercise of this Warrant, no provisions of this Warrant, and no enumeration herein of the rights or privileges of the Registered
Holder shall cause such Registered Holder to be a shareholder of the Company for any purpose by virtue hereof.

 

12.2.  Amendment. 
The provisions of this Warrant may be modified at any time by agreement of the parties. Any such agreement hereafter made shall
be ineffective to modify this Warrant in any respect unless in writing and signed by the parties against whom enforcement of the
modification or discharge is sought.

 

12.3.  Notices. 
Any notice under this Warrant shall be in writing, and any written notice or other document shall be deemed to have been duly given
(i) on the date of personal service on the parties, (ii) on the third business day after mailing, if the document is
mailed by first class mail, (iii) one day after being sent by professional or overnight courier or messenger service guaranteeing
one-day delivery, or (iv) on the date of transmission if sent by telecopy or other means of electronic transmission resulting
in written copies, with receipt confirmed. Any such notice shall be delivered or addressed to the parties at the addresses set
forth below or at the most recent address specified by the addressee through written notice under this provision. Failure to conform
to the above requirements shall not defeat the effectiveness of notice actually received by the addressee.

either of that term or condition as it applies on a subsequent occasion or of any other term or condition.

The headings in this Warrant are for purposes of convenience and reference only, and shall not be deemed to constitute a part hereof.
