in whole or in part, at any time on any Business Day on or after the opening of business on such Business Day, commencing with
the Effective Date, and prior to 11:59 P.M.  Eastern Time on the Expiration Date, by (i) delivery of a written notice,
in the form of the subscription notice attached as Exhibit A hereto (the “Exercise Notice”), of
such Holder’s election to exercise this Warrant, which notice shall specify the number of Warrant Shares to be purchased
which shall not be less than 5,000 shares in each case (or if less than 5,000 shares are available to purchase from the Company
pursuant to this Warrant), such lesser amount (as such minimum number may be adjusted pursuant to Section 9), (ii) payment
to the Company of an amount equal to the Warrant Exercise Price(s) applicable to the Warrant Shares being purchased, multiplied
by the number of Warrant Shares (at the applicable Warrant Exercise Price) as to which this Warrant is being exercised (plus any
applicable issue or transfer taxes) (the “Aggregate Exercise Price”) in cash or wire transfer of immediately
available funds and (iii) the surrender of this Warrant (or an indemnification undertaking with respect to this Warrant in
the case of its loss, theft or destruction) to a common carrier for overnight delivery to the Company as soon as practicable following
such date. Upon delivery of the Exercise Notice and Aggregate Exercise Price referred to in clause (ii) above the Holder of
this Warrant shall be deemed for all corporate purposes to have become the Holder of record of the Warrant Shares with respect
to which this Warrant has been exercised. Notwithstanding anything herein to the contrary, the Holder shall not be required to
physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and
the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation
within three (3) trading days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this
Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of
lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant
Shares purchased. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions
of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available
for purchase hereunder at any given time may be less than the amount stated on the face hereof.

Warrant
Holder: Kubera North America, Inc.

 

(b)            The
Company shall use best efforts to cause the Warrant Shares purchased hereunder to be transmitted by its transfer agent to the Holder
by crediting the account of the Holder’s broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian
system (“DWAC”) if the Company is then a participant in such system if there is an effective registration statement
permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder, and otherwise by physical delivery
of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of
Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of
Exercise by the time and date that is no later than 11:00 am, Eastern time, on the tenth (10th) trading day after the latest of
(A) the delivery to the Company of the Notice of Exercise, (B) surrender of this Warrant (if required) and (C) payment
of the Aggregate Exercise Price (such date, the “Warrant Share Delivery Date”). In no event may the Warrants
be settled in cash. If there is no effective registration statement permitting the resale of the Warrant Shares, then any Warrant
Shares delivered upon exercise of this Warrant shall be restricted shares. The Company has no obligation of any kind to register
the Warrant Shares for resale. The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated
to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant
has been exercised, with payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any,
pursuant to Section 3(e) prior to the issuance of such shares, having been paid.

 

(c)            Unless
the rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, as soon as practicable
and in no event later than thirty (30) Business Days after any exercise and at its own expense, upon written request of the Holder
issue a new Warrant identical in all respects to this Warrant exercised except it shall represent rights to purchase the number
of Warrant Shares purchasable immediately prior to such exercise under this Warrant exercised, less the number of Warrant Shares
with respect to which such Warrant is exercised.

 

(d)            No
fractional Warrant Shares are to be issued upon any exercise of this Warrant, but rather the number of Warrant Shares issued upon
such exercise of this Warrant shall be rounded up or down to the nearest whole number.

 

(e)            Issuance
of Warrant Shares 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 Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall
be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that, in the
event Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall
be accompanied by the Warrant Power in the form attached hereto as Exhibit B duly executed by the Holder, and the Company
may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

Warrant
Holder: Kubera North America, Inc.

 

(f)            If
at any time the Company proposes to merge or consolidate with or into any other corporation, effect any reorganization, or sell
or convey all or substantially all of its assets to any other entity, then, as a condition of such reorganization, consolidation,
merger, sale or conveyance, the Company or its successor, as the case may be, shall enter into a supplemental agreement to make
lawful and adequate provision whereby the Holder shall have the right to receive, upon exercise of this Warrant, the kind and amount
of equity securities which would have been received upon such reorganization, consolidation, merger, sale or conveyance by a Holder
of a number of shares of Common Stock equal to the number of shares issuable upon exercise of this Warrant immediately prior to
such reorganization, consolidation, merger, sale, or conveyance. The Company shall give the Holder of this Warrant ten (10) Business
Days’ prior written notice of the proposed effective date of any such merger, consolidation, reorganization, sale or conveyance,
and the Company shall also give the Holder of this Warrant ten (10) Business Days’ prior written notice of the commencement
of the Company’s voluntary or involuntary dissolution, liquidation or winding up. If the property to be received upon such
merger, consolidation, reorganization, sale or conveyance is not equity securities, and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

 

(g)            If,
at any time while this Warrant is outstanding, the Company declares or makes 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, shares 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”), then, in each
such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated
therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant immediately
before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record
holders of shares of Common Stock are to be determined for the participation in such Distribution.

 

Section 4.               Piggyback
Registration Rights.

 

(a)            Whenever
the Company proposes a Registration and the registration form to be used may be used for the registration of Warrant Shares (a
 “Piggyback Registration”), the Company will give ten (10) days prior written notice to the Holder of its
intention to effect such a Registration and include in such Registration (and in all related registrations or qualifications under
blue sky laws or in compliance with other registration requirements and in any related underwriting) all Warrant Shares with respect
to which the Company has received written requests for inclusion therein within five (5) days after the receipt of the Company’s
notice.

 

(b)            The
Company will include in such Registration all securities requested to be included in such Registration; provided that if
the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included
in such Registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the
offering, the Company will include in such registration (i) first, the securities the Company proposes to sell, (ii) second,
the number of securities, if any, requested to be included in such Registration pro rata, if necessary, among the holders
of such other securities who have demand registration rights; (iii) third, the number of securities, if any, requested
to be included in such Registration pro rata, if necessary, among the holders of such other securities who have piggyback
registration rights, including the Holder, and (iv) fourth, other securities, if any, requested to be included in such
registration pro rata, if necessary, among the holders of such other securities on the basis of the number of such other
securities requested to be included therein by each such holder.

Warrant Holder: Kubera North America, Inc. 

 

(c)            During
such time as the Holder may be engaged in a distribution of securities pursuant to an underwritten Piggyback Registration, the
Holder shall distribute any Warrant Shares held by the Holder only under the registration statement and solely in the manner described
therein.

 

(d)            The
Company will pay all Registration Expenses in connection with any Piggyback Registration whether or not such Piggyback Registration
has become effective.

 

Section 5.               Covenants
as to Common Stock. The Company hereby covenants and agrees as follows:

 

(a)            This
Warrant is duly authorized and validly issued.

 

(b)            All
Warrant Shares which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly
issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof.

 

(c)            The
Company will at all times have authorized and reserved at least one hundred percent (100%) of the number of shares of Common Stock
needed to provide for the exercise of the rights then represented by this Warrant and the par value of said shares will at all
times be less than or equal to the applicable Warrant Exercise Price.

 

(d)            The
Company will not, by amendment of its Articles of Incorporation or through any 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 by it hereunder, but will at all times in good faith assist in the carrying out
of all the provisions of this Warrant.

 

Section 6.               Warrant
Holder Not Deemed a Stockholder. Except as otherwise specifically provided herein, no Holder, as such, of this Warrant
shall be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the Company for any purpose,
nor shall anything contained in this Warrant be construed to confer upon the Holder hereof, as such, any of the rights of a stockholder
of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock,
reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription
rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which Holder is then entitled to receive upon
the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities
on such Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether
such liabilities are asserted by the Company or by creditors of the Company.

Holder: Kubera North America, Inc.

 

Section 7.               Representations
of Holder. The Holder of this Warrant, by the acceptance hereof, represents that it is acquiring this Warrant and the
Warrant Shares for its own account for investment only and not with a view towards, or for resale in connection with, the public
sale or distribution of this Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities
Act; provided, however, that by making the representations herein, the Holder does not agree to hold this Warrant or any of the
Warrant Shares for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant Shares
at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act and other applicable
securities laws. The Holder of this Warrant further represents, by acceptance hereof, that, as of this date, such Holder is an
 “accredited investor” as such term is defined in Rule 501(a)(1) of Regulation D promulgated by the Securities
and Exchange Commission under the Securities Act (an “Accredited Investor”). Upon exercise of this Warrant
the Holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Warrant Shares
so purchased are being acquired solely for the Holder’s own account and not as a nominee for any other party, for investment,
and not with a view toward distribution or resale and that such Holder is an Accredited Investor. If such Holder cannot make such
representations because they would be factually incorrect, it shall be a condition to such Holder’s exercise of this Warrant
that the Company receive such other representations as the Company considers reasonably necessary to assure the Company that the
issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws.

 

Section 8.               Ownership
and Transfer.

 

(a)            The
Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by
notice to the Holder hereof), a register for this Warrant, in which the Company shall record the name and address of the person
or entity in whose name this Warrant has been issued, as well as the name and address of each transferee. The Company may treat
the person in whose name any Warrant is registered on the register as the owner and Holder thereof for all purposes, notwithstanding
any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant.

 

(b)            The
Company agrees that, subject to the satisfaction of the conditions set forth in this Section 8(b), the Holder shall be entitled
to transfer all or any portion of this Warrant or of the Warrant Shares (i) in the case that the Holder is an incorporated
or other entity, to an Affiliated Entity of the Holder or (ii) in the case that the Holder is a natural person, for bona fide
estate planning purposes, either during his or her lifetime or on death by will or intestacy to his or her spouse, child (natural
or adopted), or any other direct lineal descendant of such Holder (or his or her spouse) (all of the foregoing collectively referred
to as “family members”), or to any custodian or trustee of any trust, partnership or limited liability company for
the benefit of, or the ownership interests of which are owned wholly by, such Holder or any such family members. The Holder agrees
not to make any transfer or disposition of the Warrant or all or any portion of the Warrant Shares to any Affiliated Entity, family
member or custodian or trustee or to any other Person unless and until (i) the Holder shall have notified the Company of the
proposed disposition and shall have furnished the Company with a reasonably detailed statement of the circumstances surrounding
the proposed disposition and (ii) the transferee has agreed in writing for the benefit of the Company to be bound by the terms
of this Warrant and any other stockholder or similar agreement among substantially all other holders of Common Stock as reasonably
requested by the Company. Any transfer in violation of this Section 8(b) shall be void ab initio.

Section 9.               Adjustment
of Warrant Exercise Price and Number of Shares. The Warrant Exercise Price and the number of shares of Common Stock
issuable upon exercise of this Warrant shall be adjusted from time to time as follows:

 

(a)            Adjustment
of Warrant Exercise Price upon Subdivision or Combination of Common Stock. If the Company at any time after the date of issuance
of this Warrant 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, any Warrant Exercise Price in effect immediately prior to such subdivision
will be proportionately reduced and the number of shares of Common Stock obtainable upon exercise of this Warrant will be proportionately
increased. If the Company at any time after the date of issuance of this Warrant 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, any Warrant Exercise
Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares issuable
upon exercise of this Warrant will be proportionately decreased. Any adjustment under this Section 9(a) shall become
effective at the close of business on the date the subdivision or combination becomes effective.

 

(b)            Notices.
Promptly upon any adjustment of the Warrant Exercise Price, the Company will give written notice thereof to the Holder of this
Warrant, setting forth in reasonable detail, and certifying, the calculation of such adjustment.

 

Section 10.             Mutilated
or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly, on receipt
of an indemnification undertaking (or, in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like denomination
and tenor as this Warrant so lost, stolen, mutilated or destroyed.

 

Section 11.             Notice.
Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Warrant must
be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt,
when sent by facsimile (provided confirmation of receipt is received by the sending party transmission is mechanically or electronically

Section 12.             Date.
The date of this Warrant is set forth on page 1 hereof. This Warrant, in all events, shall be wholly void and of no effect

and Waiver. Except as otherwise provided herein, the provisions of the Warrants may be amended by a writing executed

Section 14.             Descriptive
Headings; Governing Law. The descriptive headings of the several sections and paragraphs of this Warrant are inserted
for convenience only and do not constitute a part of this Warrant. All questions concerning the construction, validity, enforcement
and interpretation of this Warrant shall be governed by the internal laws of the State of Delaware, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdictions) that would
cause the application of the laws of any jurisdictions other than the State of Delaware. Each party hereby irrevocably submits
to the exclusive jurisdiction of the state and federal courts sitting in Delaware, for the adjudication of any dispute hereunder
or in connection herewith or therewith, or with any transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction
of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action
or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served
in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this
Warrant 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 manner permitted by law.

(the “Lock-Up Agreement”) pursuant to which it will not, for a period of no more than 180 days following the
effective date of the first registration statement of the Company’s initial public offering, offer, sell or otherwise dispose
of the Warrant Shares or any other equity securities of the Company held. The Lock-up Agreement shall provide that the provisions
thereof may be waived with the consent of the Company and the representative underwriter.

Section 3.            
Exercise of Warrant.

 

(a)         Subject
to the terms and conditions hereof, this Warrant may be exercised by the Holder hereof then registered on the books of the
Company, in whole or in part, at any time on any Business Day on or after the opening of business on such Business Day,
commencing with the Effective Date, and prior to 11:59 P.M. Eastern Time on the Expiration Date, by (i) delivery of a written
notice, in the form of the subscription notice attached as Exhibit A hereto (the “Exercise
Notice”), of such Holder’s election to exercise this Warrant, which notice shall specify the number of
Warrant Shares to be purchased which shall not be less than 1,000 shares in each case (or if less than 1,000 shares are
available to purchase from the Company pursuant to this Warrant), such lesser amount (as such minimum number may be adjusted
pursuant to Section 8), (ii) payment to the Company of an amount equal to the Warrant Exercise Price(s) applicable to the
Warrant Shares being purchased, multiplied by the number of Warrant Shares (at the applicable Warrant Exercise Price) as to
which this Warrant is being exercised (plus any applicable issue or transfer taxes) (the “Aggregate Exercise
Price”) in cash or wire transfer of immediately available funds and (iii) the surrender of this Warrant (or an
indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction) to a common carrier
for overnight delivery to the Company as soon as practicable following such date. Upon delivery of the Exercise Notice and
Aggregate Exercise Price referred to in clause (ii) above the Holder of this Warrant shall be deemed for all corporate
purposes to have become the Holder of record of the Warrant Shares with respect to which this Warrant has been exercised.
Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the
Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in
full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) trading days of
the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases
of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding
number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The
Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this
paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for
purchase hereunder at any given time may be less than the amount stated on the face hereof.

 

    -3- 

     

    

 

(b)        
The Company shall use best efforts to cause the Warrant Shares purchased hereunder to be transmitted by its transfer agent
to the Holder by crediting the account of the Holder’s broker with The Depository Trust Company through its Deposit or Withdrawal
at Custodian system (“DWAC”) if the Company is then a participant in such system if there is an effective registration
statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder, and otherwise by physical
delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the
number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the
Notice of Exercise by the time and date that is no later than 11:00 am, Eastern time, on the tenth (10th) trading day after the
latest of (A) the delivery to the Company of the Notice of Exercise, (B) surrender of this Warrant (if required) and (C) payment
of the Aggregate Exercise Price (such date, the “Warrant Share Delivery Date”). In no event may the Warrants
be settled in cash. If there is no effective registration statement permitting the resale of the Warrant Shares, then any Warrant
Shares delivered upon exercise of this Warrant shall be restricted shares. The Company has no obligation of any kind to register
the Warrant Shares for resale. The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated
to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant
has been exercised, with payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any,
pursuant to Section 3(e) prior to the issuance of such shares, having been paid.

 

(c)        
Unless the rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall,
as soon as practicable and in no event later than thirty (30) Business Days after any exercise and at its own expense, upon written
request of the Holder issue a new Warrant identical in all respects to this Warrant exercised except it shall represent rights
to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant exercised, less the
number of Warrant Shares with respect to which such Warrant is exercised.

 

(d)        
No fractional Warrant Shares are to be issued upon any exercise of this Warrant, but rather the number of Warrant Shares
issued upon such exercise of this Warrant shall be rounded up or down to the nearest whole number.

 

(e)        
Issuance of Warrant Shares 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 Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such
Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that, in the event Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for
exercise shall be accompanied by the Warrant Power in the form attached hereto as Exhibit B duly executed by the Holder,
and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental
thereto.

 

    -4- 

     

    

 

(f)         
 If at any time the Company proposes to merge or consolidate with or into any other corporation, effect any reorganization,
or sell or convey all or substantially all of its assets to any other entity, then, as a condition of such reorganization, consolidation,
merger, sale or conveyance, the Company or its successor, as the case may be, shall enter into a supplemental agreement to make
lawful and adequate provision whereby the Holder shall have the right to receive, upon exercise of this Warrant, the kind and amount
of equity securities which would have been received upon such reorganization, consolidation, merger, sale or conveyance by a Holder
of a number of shares of Common Stock equal to the number of shares issuable upon exercise of this Warrant immediately prior to
such reorganization, consolidation, merger, sale, or conveyance. The Company shall give the Holder of this Warrant ten (10) Business
Days’ prior written notice of the proposed effective date of any such merger, consolidation, reorganization, sale or conveyance,
and the Company shall also give the Holder of this Warrant ten (10) Business Days’ prior written notice of the commencement
of the Company’s voluntary or involuntary dissolution, liquidation or winding up. If the property to be received upon such
merger, consolidation, reorganization, sale or conveyance is not equity securities, and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

 

(g)        
If, at any time while this Warrant is outstanding, the Company declares or makes 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, shares 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”), then, in each
such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated
therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant immediately
before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record
holders of shares of Common Stock arc to be determined for the participation in such Distribution.

 

Section 4.            
Covenants as to Common Stock. The Company hereby covenants and agrees as follows:

 

(a)         
This Warrant is duly authorized and validly issued.

 

(b)        
All Warrant Shares which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance,
be validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof.

 

(c)         
The Company will at all times have authorized and reserved at least one hundred percent (100%) of the number of shares of
Common Stock needed to provide for the exercise of the rights then represented by this Warrant and the par value of said shares
will at all times be less than or equal to the applicable Warrant Exercise Price.

 

(d)         The
Company will not, by amendment of its Articles of Incorporation or through any 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 by it hereunder, but will at all times in good
faith assist in the carrying out of all the provisions of this Warrant.

 

    -5- 

     

    

 

Section 5.            
Warrant Holder Not Deemed a Stockholder. Except as otherwise specifically provided herein, no Holder, as such, of
this Warrant shall be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the Company for
any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder hereof, as such, any of the rights
of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization,
issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive
dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which Holder is then
entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as
imposing any liabilities on such Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder
of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

 

Section 6.            
Representations of Holder. The Holder of this Warrant, by the acceptance hereof, represents that it is acquiring
this Warrant and the Warrant Shares for its own account for investment only and not with a view towards, or for resale in connection
with, the public sale or distribution of this Warrant or the Warrant Shares, except pursuant to sales registered or exempted under
the Securities Act; provided, however, that by making the representations herein, the Holder does not agree to hold this Warrant
or any of the Warrant Shares for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant
Shares at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act and other
applicable securities laws. The Holder of this Warrant further represents, by acceptance hereof, that, as of this date, such Holder
is an “accredited investor” as such term is defined in Rule 501(a)(1) of Regulation D promulgated by the Securities
and Exchange Commission under the Securities Act (an “Accredited Investor”). Upon exercise of this Warrant the
Holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Warrant Shares so
purchased are being acquired solely for the Holder’s own account and not as a nominee for any other party, for investment,
and not with a view toward distribution or resale and that such Holder is an Accredited Investor. If such Holder cannot make such
representations because they would be factually incorrect, it shall be a condition to such Holder’s exercise of this Warrant
that the Company receive such other representations as the Company considers reasonably necessary to assure the Company that the
issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws.

 

Section 7.            
Ownership and Transfer.

 

(a)         
The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate
by notice to the Holder hereof), a register for this Warrant, in which the Company shall record the name and address of the person
or entity in whose name this Warrant has been issued, as well as the name and address of each transferee. The Company may treat
the person in whose name any Warrant is registered on the register as the owner and Holder thereof for all purposes, notwithstanding
any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant.

 

    -6- 

     

    

 

(b)        
 The Company agrees that, subject to the satisfaction of the conditions set forth in this Section 7(b), the Holder shall
be entitled to transfer all or any portion of this Warrant or of the Warrant Shares (i) in the case that the Holder is an incorporated
or other entity, to an Affiliated Entity of the Holder or (ii) in the case that the Holder is a natural person, for bona fide estate
planning purposes, either during his or her lifetime or on death by will or intestacy to his or her spouse, child (natural or adopted),
or any other direct lineal descendant of such Holder (or his or her spouse) (all of the foregoing collectively referred to as “family
members”), or to any custodian or trustee of any trust, partnership or limited liability company for the benefit of, or the
ownership interests of which are owned wholly by, such Holder or any such family members. The Holder agrees not to make any transfer
or disposition of the Warrant or all or any portion of the Warrant Shares to any Affiliated Entity, family member or custodian
or trustee or to any other Person unless and until (i) the Holder shall have notified the Company of the proposed disposition and
shall have furnished the Company with a reasonably detailed statement of the circumstances surrounding the proposed disposition
and (ii) the transferee has agreed in writing for the benefit of the Company to be bound by the terms of this Warrant and any other
stockholder or similar agreement among substantially all other holders of Common Stock as reasonably requested by the Company.
Any transfer in violation of this Section 7(b) shall be void ab initio.

 

Section 8.           
Adjustment of Warrant Exercise Price and Number of Shares. The Warrant Exercise Price and the number of shares of
Common Stock issuable upon exercise of this Warrant shall be adjusted from time to time as follows:

 

(a)        
Adjustment of Warrant Exercise Price upon Subdivision or Combination of Common Stock. If the Company at any
time after the date of issuance of this Warrant 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, any Warrant Exercise Price in effect
immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock obtainable upon
exercise of this Warrant will be proportionately increased. If the Company at any time after the date of issuance of this Warrant
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, any Warrant Exercise Price in effect immediately prior to such combination will be proportionately
increased and the number of Warrant Shares issuable upon exercise of this Warrant will be proportionately decreased. Any adjustment
under this Section 8(a) shall become effective at the close of business on the date the subdivision or combination becomes effective.

 

(b)        
Notices. Promptly upon any adjustment of the Warrant Exercise Price, the Company will give written notice thereof
to the Holder of this Warrant, setting forth in reasonable detail, and certifying, the calculation of such adjustment.

 

Section 9.           
Mutilated or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly,
on receipt of an indemnification undertaking (or, in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like
denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

 

Section 10.          Notice.
Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Warrant must
be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when
sent by facsimile (provided confirmation of receipt is received by the sending party transmission is mechanically or
electronically generated and kept on file by the sending party); or (iii) one Business Day after deposit with a nationally
recognized overnight delivery service, in each case properly addressed to the party to receive the same. The addresses and
facsimile numbers for such communications shall be:

Date. The date of this Warrant is set forth on page 1 hereof. This Warrant, in all events, shall be wholly void and
of no effect after the close of business on the Expiration Date.

Amendment and Waiver. Except as otherwise provided herein, the provisions of the Warrants may be amended by a writing
executed by both the Company and the Holder.

 

Section 13.           Descriptive
Headings; Governing Law. The descriptive headings of the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. All questions concerning the construction, validity,
enforcement and interpretation of this Warrant shall be governed by the internal laws of the State of Delaware, without
giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other
jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Delaware. Each party
hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in Delaware, for the
adjudication of any dispute hereunder or in connection herewith or therewith, or with any transaction contemplated hereby or
discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that

inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives
personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy
thereof to such party at the address for such notices to it under this Warrant and agrees that such service shall constitute

lock-up agreement (the “Lock-Up Agreement”) pursuant to which it will not, for a period of no more than 180
days following the effective date of the first registration statement of the Company’s initial public offering, offer, sell
or otherwise dispose of the Warrant Shares or any other equity securities of the Company held. The Lock-up Agreement shall provide
that the provisions thereof may be waived with the consent of the Company and the representative underwriter.
