Section
2. Exercise of Warrant.


 


(a)
Exercise and Payment. The Warrant Holder may exercise this Warrant in whole or in part, at any time or from time to time
on any Business Day beginning six months after the date on which this Warrant is issued on or prior to the Expiration Date, by
delivering to the Company either the original Warrant or a lost warrant affidavit, a duly executed notice (a “Notice
of Exercise”) in the form of Exhibit A and by payment to the Company of the Exercise Price per Warrant Share,
at the election of the Warrant Holder, either (i) by wire transfer of immediately available funds to the account of the Company
in an amount equal to the Exercise Amount, (ii) by receiving from the Company the number of Warrant Shares equal to (A) the number
of Warrant Shares as to which this Warrant is being exercised minus (B) the number of Warrant Shares having a value, based on
the Closing Price on the trading day immediately prior to the date of such exercise (or if there is no such Closing Price, then
based on the Appraised Value as of such day), equal to the Exercise Amount, or (iii) any combination of the foregoing. The Company
acknowledges that the provisions of clause (ii) are intended, in part, to ensure that a full or partial exchange of this Warrant
pursuant to such clause (ii) will qualify as a conversion, within the meaning of paragraph (d)(3)(ii) of Rule 144 under the Securities
Act. At the request of any Holder, the Company will accept reasonable modifications to the exchange procedures provided for in
this Section in order to accomplish such intent. For all purposes of this Warrant (other than this Section 2(a)), any reference
herein to the exercise of this Warrant shall be deemed to include a reference to the exchange of this Warrant into Shares in accordance
with the terms of clause (ii).


 


(b)
Effectiveness and Delivery. As soon as practicable but not later than five Business Days after the Company shall have received
such Notice of Exercise, (provided requisite payment shall have been received prior to such date), the Company shall execute and
deliver or cause to be executed and delivered, in accordance with such Notice of Exercise, a certificate or certificates representing
the number of Shares specified in such Notice of Exercise, issued in the name of the Warrant Holder or in such other name or names
of any Person or Persons designated in such Notice of Exercise. This Warrant shall be deemed to have been exercised and such Share
certificate or certificates shall be deemed to have been issued, and the Warrant Holder or other Person or Persons designated
in such Notice of Exercise shall be deemed for all purposes to have become a holder of record of Shares, all as of the date that
such Notice of Exercise.


 


(c)
Surrender of Warrant. The Warrant Holder shall surrender this Warrant to the Company when it delivers the Notice of Exercise,
and in the event of a partial exercise of the Warrant, the Company shall execute and deliver to the Warrant Holder, at the time
the Company delivers the Share certificate or certificates issued pursuant to such Notice of Exercise, a new Warrant for the unexercised
portion of the Warrant, but in all other respects identical to this Warrant.


 


(d)
Legend. Each certificate for Warrant Shares issued upon exercise of this Warrant, unless at the time of exercise such Warrant
Shares are registered under the Securities Act, shall bear the following legend:


 


THIS
SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED
IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER SAID ACT AND ANY APPLICABLE STATE SECURITIES LAWS, UNLESS AN
EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.


 




    	4



    	 



    

 


Any
certificate for Warrant Shares issued at any time in exchange or substitution for any certificate bearing such legend (unless
at that time such Warrant Shares are registered under the Securities Act) shall also bear such legend unless, in the written opinion
of counsel selected by the holder of such certificate (who may be an employee of such holder), which counsel and opinion shall
be reasonably acceptable to the Company, the Warrant Shares represented thereby need no longer be subject to restrictions on resale
under the Securities Act. If the Warrant is exercised when there is an effective registration statement covering the underlying
Warrant Shares, the certificate for the Warrant Shares shall not bear a legend.


 


(e)
No Fractional Shares. No fractional Shares shall be issued by the Company in connection with any exercise of this Warrant.
If any fractional Shares would, but for this restriction, be issuable upon an exercise of the Warrant, in lieu of delivering such
fractional Shares, the number of Shares to be issued shall be rounded down to the next whole number and the Company shall pay
to the Warrant Holder, in cash, an amount equal to the same fraction times the Closing Price on the trading day immediately prior
to the date of such exercise (or if there is no such Closing Price, then based on the Appraised Value as of such day).


 


(f)
Expenses and Taxes. Except for taxes payable with respect to any income or revenue realized or recognized by the Warrant
Holder or any transferee thereof, the Company shall pay all expenses, taxes and owner charges payable in connection with the preparation,
issuance and delivery of certificates for the Warrant Shares and any new Warrants, except that if the certificates for the Warrant
Shares or the new Warrants are to be registered in a name or names other than the name of the Warrant Holder, funds sufficient
to pay all transfer taxes payable as a result of such transfer shall be paid by the Warrant Holder at the time of its delivery
of the Notice of Exercise or promptly upon receipt of a written request by the Company for payment.


 


Section
3. Validity of Warrant and Issuance of Shares.


 


(a)
The Company represents and warrants that this Warrant has been duly authorized, is validly issued, and constitutes the valid and
binding obligation of the Company.


 


(b)
The Company further represents and warrants that on the date hereof it has duly authorized and reserved, and the Company hereby
agrees that it will at all times until the Expiration Date have duly authorized and reserved, such number of Shares as will be
sufficient to permit the exercise in full of the Warrant, and that all such Shares are and will be duly authorized and, when issued
upon exercise of the Warrant, will be validly issued, fully paid and non-assessable, and free and clear of all security interests,
claims, liens, equities and other encumbrances.


 


Section
4. Antidilution Provisions. The Exercise Price in effect at any time, and the number of Warrant Shares that may be purchased
upon any exercise of the Warrant, shall be subject to change or adjustment as follows:


 


(a)
Share Reorganization. If the Company shall subdivide its outstanding Shares into a greater number of Shares, by way of
a stock split, stock dividend or otherwise, or consolidate its outstanding Shares into a smaller number of Shares (any such event
being herein called a “Share Reorganization”), then (i) the Exercise Price shall be adjusted, effective
immediately after the effective date of such Share Reorganization, to a price determined by multiplying the Exercise Price in
effect immediately prior to such effective date by a fraction, the numerator of which shall be the number of Shares outstanding
on such effective date before giving effect to such Share Reorganization and the denominator of which shall be the number of Shares
outstanding after giving effect to such Share Reorganization, and (ii) the number of Shares subject to purchase upon exercise
of this Warrant shall be adjusted, effective at such time, to a number determined by multiplying the number of Shares subject
to purchase immediately before such Share Reorganization by a fraction, the numerator of which shall be the number of Shares outstanding
after giving effect to such Share Reorganization and the denominator of which shall be the number of Shares outstanding immediately
before giving effect to such Share Reorganization.


 




    	5



    	 



    

 


(b)
Share Distribution. [Reserved]


 


(c)
Special Distributions; Above Market Purchases of Securities.


 


(i)
If the Company shall issue or distribute to any holder or holders of Shares evidences of indebtedness, any other securities of
the Company or any cash, property or other assets (excluding (i) a Share Reorganization and (ii) a Share Distribution), whether
or not accompanied by a purchase, redemption or other acquisition of Shares (any such nonexcluded event being herein called a
“Special Distribution”), then the Warrant Holder shall be entitled to a pro-rata Share of such Special
Distribution as though the Warrant Holder had fully exercised this Warrant immediately prior to the record date for such Special
Distribution, and the Company shall pay or distribute such pro-rata share to Warrant Holder when paid or distributed to the holders
of the Shares. A reclassification of the Shares (other than a change in par value, or from par value to no par value or from no
par value to par value) into shares of any other class of stock shall be deemed to be a distribution by the Company to the holders
of its Shares of such class of stock and, if the outstanding Shares shall be changed into a larger or smaller number of Shares
as part of such reclassification, a Share Reorganization.


 


(ii)
If, at any time after the date hereof, the Company or any Subsidiary shall repurchase (a “Repurchase”),
by self-tender offer or otherwise, any securities of the Company at an aggregate repurchase price that exceeds the aggregate Market
Price for the securities repurchased determined as of the Business Day immediately prior to the earliest of (i) the date of such
Repurchase, (ii) the commencement of an offer to repurchase or (iii) the public announcement of either (such date being referred
to as the “Determination Date”), then the Exercise Price and the number of Warrant Shares issuable upon exercise of
this Warrant shall be adjusted as follows:


 


The
Exercise Price shall be reduced to an amount equal to the product of (A) the Exercise Price in effect immediately prior to such
issuance or sale times (B) a fraction, (I) the numerator of which shall be (x) the product of (1) the Market Price for the Shares
as of the Determination Date times (2) the number of Shares outstanding immediately following the consummation of the Repurchase
less (y) the Repurchase Premium (as defined below), and (II) the denominator of which shall be (x) the product of (1) the Market
Price for the Shares as of the Determination Date times (2) the number of Shares outstanding immediately following the consummation
of the Repurchase.


 


The
number of Warrant Shares issuable upon exercise of this Warrant shall be increased to the number of Shares determined by multiplying
(x) the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such distribution times (y) a fraction
(1) the numerator of which shall be the Exercise Price in effect immediately prior to the adjustment in clause (A) of this Section
4(c)(ii) and (2) the denominator of which shall be the Exercise Price in effect immediately after such adjustment.


 




    	6



    	 



    

 


The
amount by which the aggregate repurchase price for all securities repurchased in any Repurchase (including for such purposes any
fees or other direct or indirect consideration payable in connection therewith) exceeds the aggregate Market Price for such securities
is referred to as the “Repurchase Premium.”


 


(d)
Capital Reorganization. Without limiting any of the other provisions hereof, if any (i) capital reorganization; (ii) reclassification
of the capital stock of the Company; (iii) merger, consolidation or reorganization or other similar transaction or series of related
transactions which results in the voting securities of the Company outstanding immediately prior thereto representing immediately
thereafter (either by remaining outstanding or by being converted into voting securities of the surviving or acquiring entity)
less than 50% of the combined voting power of the voting securities of or economic interests in the Company or such surviving
or acquiring entity outstanding immediately after such merger, consolidation or reorganization; (iv) sale, lease, license, transfer,
conveyance or other disposition of all or substantially all of the assets of the Company; (v) sale of shares of capital stock
of the Company, in a single transaction or series of related transactions, representing at least 50% of the voting power of the
voting securities of or economic interests in the Company; or (vi) the acquisition by any “person” (together with
his, her or its Affiliates) or “group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act) acquires,
directly or indirectly, the beneficial ownership (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) of
outstanding shares of capital stock and/or other equity securities of the Company, in a single transaction or series of related
transactions (including, without limitation, one or more tender offers or exchange offers), representing at least 50% of the voting
power of or economic interests in the then outstanding shares of capital stock of the corporation (each of (i)-(vi) above a “Corporate
Reorganization”) shall be effected, then the Company shall use its best efforts to ensure that lawful and adequate
provision shall be made whereby each Warrant Holder shall thereafter continue to have the right to purchase and receive upon the
basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares issuable upon exercise of the Warrants
held by such Warrant Holder, shares of stock in the surviving or acquiring entity (“Acquirer”), as the
case may be, such that the aggregate value of the Warrant Holder’s warrants to purchase such number of shares, where the
value of each new warrant to purchase one share in the Acquirer is determined in accordance with the Black-Scholes Option Pricing
formula set forth in Appendix (A) hereto, is equivalent to the aggregate value of the Warrants held by such Warrant Holder,
where the value of each Warrant to purchase one share in the Company is determined in accordance with the Black-Scholes Option
Pricing formula set forth Appendix (B) hereto. Furthermore, the new warrants to purchase shares in the Acquirer referred to herein
shall have the same expiration date as the Warrants, and shall have a strike price, KAcq, that is calculated in accordance
with Appendix (A) hereto. For the avoidance of doubt, if the surviving or acquiring entity, as the case may be, is a member
of a consolidated group for financial reporting purposes, the “Acquirer” shall be deemed to be the parent of such
consolidated group for purposes of this Section 4(d) and Appendix (A) hereto.


 




    	7



    	 



    

 


Moreover,
appropriate provision shall be made with respect to the rights and interests of each Warrant Holder to the end that the provisions
hereof (including, without limitation, provision for adjustment of the Warrant Price) shall thereafter be applicable, as nearly
equivalent as may be practicable in relation to any shares of stock thereafter deliverable upon the exercise thereof. The Company
shall not effect any such Corporate Reorganization unless prior to or simultaneously with the consummation thereof the successor
corporation resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other
appropriate corporation or entity shall assume by written instrument, reasonably deemed by the Board of Directors of the Company
and the Requisite Holders to be satisfactory in form and substance, the obligation to deliver to the holder of the Warrants, at
the last address of such holder appearing on the books of the Company, such shares of stock, as, in accordance with the foregoing
provisions, such holder may be entitled to purchase, and the other obligations under these Warrants. The provisions of this Section
4(d) shall similarly apply to successive Corporate Reorganizations. If the Company, in spite of using its best efforts, is unable
to cause these Warrants to continue in full force and effect until the Expiration Date in connection with any Corporate Reorganization,
then the Company shall pay the Warrant Holders an amount per Warrant to purchase one share in the Company that is calculated in
accordance with the Black-Scholes Option Pricing formula set forth in Appendix (B) hereto. Such payment shall be made in cash
in the event that the Corporate Reorganization results in the Company or the shareholders of the Company receiving cash from the
Acquirer at the closing of the transaction, and shall be made in shares of the Company (with the value of each share in the Company
is determined according to SCorp in Appendix (B) hereto) for all other Corporate Reorganizations. In the event
that a Corporate Reorganization involves the payment of cash as well as other securities, such payment to the Warrant Holders
shall be also be made in both cash and shares in the same proportion as the cash and non-cash portions of the considerations.


 


(e)
Adjustment Rules.


 


(i)
Any adjustments pursuant to this Section 4 shall be made successively whenever any event referred to herein shall occur,
except that, notwithstanding any other provision of this Section 4, no adjustment shall be made to the number of Warrant
Shares to be delivered to the Warrant Holder (or to the Exercise Price) if such adjustment represents less than 1% of the number
of Warrant Shares previously required to be so delivered, but any lesser adjustment shall be carried forward and shall be made
at the time and together with the next subsequent adjustment which together with any adjustments so carried forward shall amount
to 1% or more of the number of Warrant Shares to be so delivered.


 


(ii)
No adjustments shall be made pursuant to this Section 4 in respect of the issuance of Warrant Shares upon exercise of the
Warrant;


 


(iii)
If the Company shall take a record of the holders of its Shares for any purpose referred to in this Section 4, then (x)
such record date shall be deemed to be the date of the issuance, sale, distribution or grant in question and (y) if the Company
shall legally abandon such action prior to effecting such action, no adjustment shall be made pursuant to this Section 4
in respect of such action.


 


(iv)
In computing adjustments under this Section 4, (A) fractional interests in Shares shall be taken into account to the nearest
one-thousandth of a Share, and (B) calculations of the Exercise Price shall be carried to the nearest one-thousandth of one cent.


 


(f)
Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would
require an adjustment pursuant to this Section 4, the Company shall take any action which may be necessary, including obtaining
regulatory approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable
all Shares which the Warrant Holder is entitled to receive upon exercise of the Warrant.


 




    	8



    	 



    

 


(g)
Notice of Adjustment. Not less than 20 days prior to the record date or effective date, as the case may be, of any action
which requires or might require an adjustment or readjustment pursuant to this Section 4, the Company shall give notice
to the Warrant Holder of such event, describing such event in reasonable detail and specifying the record date or effective date,
as the case may be, and, if determinable, the required adjustment and computation thereof. If the required adjustment is not determinable
as the time of such notice, the Company shall give notice to the Warrant Holder of such adjustment and computation as soon as
reasonably practicable after such adjustment becomes determinable. In connection with any such adjustment or readjustment, at
its sole cost and expense, the Company will also cause independent certified public accountants of recognized national standing
(which may be the regular auditors of the Company) selected by the Company to verify its computations and, in connection with
the preparation of the Company’s quarterly financial statements prepare a report setting forth such adjustment or readjustment
and showing in reasonable detail the method of calculation thereof and the facts upon which such adjustment or readjustment is
based, including a statement of (i) the consideration received or to be received by the Company for any Share Distribution issued
or sold or deemed to have been issued, (ii) the number of Shares outstanding or deemed to be outstanding, and (iii) the Exercise
Price in effect immediately prior to such issue or sale and as adjusted and readjusted (if required by this Section 4)
on account thereof. The Company will forthwith mail a copy of each such report to the Warrant Holder and will, upon the written
request at any time of the Warrant Holder, furnish to such holder a like report setting forth the Exercise Price at the time in
effect and showing in reasonable detail how it was calculated. The Company will also keep copies of all such reports at its office
and will cause the same to be available for inspection at such office during normal business hours by the Warrant Holder or any
prospective purchaser of this Warrant designated by the Warrant Holder.


 


(h)
Subsequent Warrants. Irrespective of any adjustments in the Exercise Price or the number of Warrant Shares issuable upon
exercise of this Warrant, any successor or replacement warrants issued theretofore or thereafter may continue to express the same
Exercise Price per Share and number and kind of Warrant Shares as are stated in this Warrant.


 


(i)
Disputes. Any dispute which arises between the Warrant Holder and the Company with respect to the calculation of the adjusted
Exercise Price or Warrant Shares issuable upon exercise shall be determined by the independent auditors of the Company, and such
determination shall be binding upon the Company and the holders of the Warrants and the Warrant Shares if made in good faith and
without manifest error.


 


(j)
Other Actions Affecting Shares.


 


(i)
Equitable Equivalent. In case any event shall occur as to which the provisions of this Section 4 set forth above
hereof are not strictly applicable but the failure to make any adjustment would not, in the opinion of the Warrant Holder, fairly
protect the purchase rights represented by this Warrant in accordance with the essential intent and principles of this Section
4, then, in each such case, at the request of the Warrant Holder, the Company shall appoint, at the Company’s expense,
a firm of independent investment bankers of recognized national standing (which shall be completely independent of the Company
and shall be satisfactory to the holder or the Requisite Holders), which shall give their opinion upon the adjustment, if any,
on a basis consistent with the essential intent and principles established in this Section 4, necessary to preserve, in
an manner so as to reduce dilution, the purchase rights represented by this Warrant. Upon receipt of such opinion, the Company
will promptly mail a copy thereof to the holder of this Warrant and shall make the adjustments described therein.


 




    	9



    	 



    

 


(ii)
No Avoidance. The Company shall not, by amendment of its certificate of incorporation or by-laws or through any consolidation,
merger, reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek
to avoid the observance or performance of any of the terms of this Warrant, but will 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 holder of this Warrant against unlimited dilution or other impairment as if the holder was a shareholder of the
Company entitled to the benefit of fiduciary duties afforded to shareholders under Delaware law.


 


(k)
Calculation of Consideration Received. The consideration for the issue or sale of any Share Distribution shall, irrespective
of the accounting treatment of such consideration:


 


(i)
insofar as it consists of cash, be computed at the amount of cash actually received by the Company without reduction for any expenses
paid or incurred by the Company or any commissions or compensations paid or concessions or discounts allowed to underwriters,
dealers or others performing similar services in connection with such issue or sale;


 


(ii)
insofar as it consists of property (including securities) other than cash actually received by the Company, be computed at the
Appraised Value thereof at the time of such issue or sale; and


 


(iii)
insofar as it consists neither of cash nor of other property, be computed as having no value.


 


(l)
Adjustment of Par Value. If for any reason (including the operation of the adjustment provisions set forth in this Warrant),
the Exercise Price on any date of exercise of this Warrant shall not be lawful and adequate consideration for the issuance of
the relevant Warrant Shares, then the Company shall take such steps as are necessary (including the amendment of its certificate
of incorporation so as to reduce the par value of the Shares) to cause such Exercise Price to be adequate and lawful consideration
on the date the payment thereof is due, but if the Company shall fail to take such steps, then the Company acknowledges that the
Warrant Holder shall have been damaged by the Company in an amount equal to an amount, which, when added to the total Exercise
Price for the relevant Warrant Shares, would equal lawful and adequate consideration for the issuance of such Warrant Shares,
and the Company irrevocably agrees that if the Warrant Holder shall then forgive the right to recover such damages from the Company,
such forgiveness shall constitute, and Company shall accept such forgiveness as, additional lawful consideration for the issuance
of the relevant Warrant Shares.


 


(m)
Appraisal.


 


(i)
If the Requisite Holders shall, for any reason whatsoever, disagree with the Company’s determination of the Appraised Value
of a Share, then such holders shall by notice to the Company (an “Appraisal Notice”) given within sixty
(60) days after the Company notifies the holders of such determination, elect to dispute such determination, and such dispute
shall be resolved as set forth in clause (ii) of this Section.


 




    	10



    	 



    

 


(ii)
The Company shall within ten (10) days after an Appraisal Notice shall have been given, engage an independent investment bank
of national repute (the “Appraiser”) selected by the Requisite Holders and retained pursuant to an engagement
letter between the Company and the Appraiser with respect to such valuation in form and substance reasonably acceptable to Requisite
Holders, to make an independent determination of the Appraised Value of a Share; such value shall be determined without deduction

(d)
Severability. In case any one or more of the provisions contained in this Warrant shall be invalid, illegal or unenforceable
in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be

closing bid or sale prices (whichever is applicable) in the over-the-counter market over the 20-day period ending three trading
days prior to the closing of the Corporate Reorganization if the Acquirer’s stock is then actively traded in the over-the-counter

Reorganization described in Section 4(d) if the Acquirer’s stock is then traded on such exchange or system, or the
annualized standard deviation of daily-log returns (using a 262-day annualization factor) of the closing bid or sale prices (whichever
is applicable) in the over-the-counter market over a 20-day trading period, determined by the Warrant Holder, that is within the
100-day trading period ending on the trading day immediately after the public announcement of the Corporate Reorganization if
the Acquirer’s stock is then actively traded in the over-the-counter market, or 0.6 (or 60%) if the Acquirer’s stock
