 Number of Shares of Common Stock: 394,737 
 Date of Issuance: December 20, 2005
(“Issuance Date”) 
  
 Maxwell Technologies, Inc.,
a Delaware corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, CASTLERIGG MASTER INVESTMENTS LTD., the registered holder hereof or
its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, upon surrender of this Warrant to Purchase Common Stock
(including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “Warrant”), at any time or times on or after the date hereof but not after 11:59 p.m., New York Time, on the Expiration Date
(as defined below), Three Hundred Ninety Four Thousand Seven Hundred Thirty Seven (394,737) fully paid nonassessable shares of Common Stock (as defined below) (the “Warrant Shares”). Except as otherwise defined herein,
capitalized terms in this Warrant shall have the meanings set forth in Section 15. This Warrant is one of the Warrants to purchase Common Stock (the “SPA Warrants”) issued pursuant to Section 1 of that certain Securities
Purchase Agreement, dated as of December 20, 2005 (the “Subscription Date”), by and among the Company and the investors (the “Buyers”) referred to therein (the “Securities Purchase Agreement”).










 1. EXERCISE OF WARRANT. 
  
 (a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation,
the limitations set forth in Section 1(f)), this Warrant may be exercised by the Holder on any day on or after the date hereof, in whole or in part, by (i) delivery of a written notice, in the form attached hereto as Exhibit A (the
“Exercise Notice”), of the Holder’s election to exercise this Warrant and (ii) (A) payment to the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this
Warrant is being exercised (the “Aggregate Exercise Price”) in cash or wire transfer of immediately available funds or (B) by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as
defined in Section 1(d)). The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have
the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. On or before the second Business Day following the date on which the Company has received
each of the Exercise Notice and the Aggregate Exercise Price (or notice of a Cashless Exercise) (the “Exercise Delivery Documents”), the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the
Exercise Delivery Documents to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the third Business Day following the date on which the Company has received all of the Exercise Delivery Documents
(the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the
Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or
(Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. Upon delivery of the Exercise Notice and Aggregate Exercise Price referred to in clause
(ii)(A) above or notification to the Company of a Cashless Exercise referred to in Section 1(d), the Holder 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, irrespective of the date of delivery of the certificates evidencing such Warrant Shares. If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented
by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than five Business Days after any exercise and at its own
expense, issue a new Warrant (in accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to
which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number. The Company shall
pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. 
  

 - 2 - 








 (b) Exercise Price. For purposes of this Warrant, “Exercise
Price” means $19.00, subject to adjustment as provided herein. 
  
 (c) Company’s Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to issue to the Holder within three (3) Business Days of receipt of the Exercise Delivery
Documents, a certificate for the number of shares of Common Stock to which the Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit the Holder’s balance account with DTC for such number
of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant, and if on or after such Business Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the
Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the
“Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate
or certificates representing such shares of Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid
Price on the date of exercise. 
  
 (d)
Cashless Exercise. Notwithstanding anything contained herein to the contrary, if a Registration Statement (as defined in the Registration Rights Agreement) covering the Warrant Shares that are the subject of the Exercise Notice (the
“Unavailable Warrant Shares”) is not available for the resale of such Unavailable Warrant Shares, the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise
contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a
“Cashless Exercise”): 
  

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

	 	 	 	 	             B


  
 For purposes of the
foregoing formula: 
  
 A= the total number of Warrant Shares with
respect to which this Warrant is then being exercised. 
  
 B= the
average of the Closing Sale Price of the shares of Common Stock (as reported by Bloomberg) on the five Trading Days immediately preceding the date of the Exercise Notice. 
  
 C= the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise. 
  

 - 3 - 








 (e) Disputes. In the case of a dispute as to the determination of the Exercise
Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 12. 
  
 (f) (i) Limitations on Exercises; Beneficial
Ownership. The Company shall not effect the exercise of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person’s
affiliates) would beneficially own (directly or indirectly through Warrant Shares or otherwise) in excess of 4.99% of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence,
the aggregate number of shares of Common Stock beneficially owned (directly or indirectly through Warrant Shares or otherwise) by such Person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this
Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such
Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its affiliates (including, without limitation, any convertible
notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this subsection, beneficial ownership
shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of
outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more
recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. In any case, the number of outstanding shares of Common Stock shall be
determined after giving effect to the conversion or exercise of securities of the Company, including the SPA Securities and the SPA Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common
Stock was reported. By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective
until the sixty-first (61st) day after such notice is delivered to the Company, and (ii) any such increase
or decrease will apply only to the Holder and not to any other holder of SPA Warrants. 
  
 (ii) Principal Market Regulation. At all times, irrespective of whether the Company is listed on the Principal Market, the Company
shall not be obligated to issue any shares of Common Stock upon exercise of this Warrant if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion or
exercise or otherwise, as applicable, of the SPA Securities and Warrants without breaching the rules or regulations of the Principal Market as if the Company were regulated by such rules or regulations (the “Exchange Cap”), except
that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of Common Stock in excess of such amount or
(B) obtains a written opinion from outside counsel to the Company that such approval 

  

 - 4 - 








 
is not required, which opinion shall be reasonably satisfactory to the Required Holders. Until such approval or written opinion is obtained, no purchaser of
the Warrants pursuant to the Securities Purchase Agreement (the “Purchasers”) shall be issued in the aggregate, upon conversion or exercise or otherwise, as applicable, of SPA Securities or Warrants, shares of Common Stock in an
amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the number of Warrants issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date and the denominator of which is
the aggregate number of Warrants issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”). In the event that any Purchaser shall sell
or otherwise transfer any of such Purchaser’s Warrants, the transferee, if a registered Holder of such Warrants, shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence
shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. In the event that any holder of Warrants shall exercise all of such holder’s Warrants into a number of shares of Common
Stock which, in the aggregate, is less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder shall be allocated
to the respective Exchange Cap Allocations of the remaining registered holders of Warrants on a pro rata basis in proportion to the aggregate number of Warrants then held by each such holder. To the extent required by the Principal Market, the
provisions of the Exchange Cap shall be modified to comply with the applicable rules and regulations of the Principal Market, provided that any such changes shall not, in the Holder’s reasonable discretion, materially change the terms of the
transaction contemplated hereby. 
  
 Notwithstanding anything in
this Warrant to the contrary, the Company shall be entitled to treat the registered holder of this Warrant as such appears in its records, as the owner of this Warrant for all purposes; provided that such records are kept current using a reasonably
satisfactory and customary method intended for such purpose. 
  
 2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted from time to time as follows: 
  
 (a) Adjustment upon Issuance of shares of Common Stock. If and whenever on or after the Subscription
Date the Company issues or sells, or in accordance with this Section 2 is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company,
but excluding shares of Common Stock deemed to have been issued by the Company in connection with any Excluded Securities (as defined in the SPA Securities) for a consideration per share (the “New Issuance Price”) less than a price
(the “Applicable Price”) equal to the Exercise Price in effect immediately prior to such issue or sale or deemed issuance or sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance,
the Exercise Price then in effect shall be reduced to an amount equal to the product of (A) the Exercise Price in effect immediately prior to such Dilutive Issuance and (B) the quotient determined by dividing (1) the sum of
(I) the product derived by multiplying the Exercise Price in effect immediately prior to such Dilutive Issuance and the number of Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any,
received by the 

  

 - 5 - 








 
Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I) the Exercise Price in effect immediately prior to such Dilutive
Issuance by (II) the number of Common Stock Deemed Outstanding immediately after such Dilutive Issuance. Upon each such adjustment of the Exercise Price hereunder, the number of Warrant Shares shall be adjusted to the number of shares of Common
Stock determined by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares acquirable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by the
Exercise Price resulting from such adjustment. For purposes of determining the adjusted Exercise Price under this Section 2(a), the following shall be applicable: 
  
 (i) Issuance of Options. If the Company grants any Options and the lowest price per share for which one share of
Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common Stock shall
be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 2(a)(i), the “lowest price per share for which one share
of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such Convertible Securities” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company
with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option. No further adjustment of
the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon
conversion, exercise or exchange of such Convertible Securities. 
  
 (ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange
thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share.
For the purposes of this Section 2(a)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange” shall be equal to the sum of the lowest amounts of consideration (if
any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security. No further adjustment of the Exercise
Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if 

  

 - 6 - 








 
any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made
pursuant to other provisions of this Section 2(a), no further adjustment of the Exercise Price or number of Warrant Shares shall be made by reason of such issue or sale. 
  
 (iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional
consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases
or decreases at any time, the Exercise Price and the number of Warrant Shares in effect at the time of such increase or decrease shall be adjusted to the Exercise Price and the number of Warrant Shares which would have been in effect at such time
had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes
of this Section 2(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding sentence, then such
Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this
Section 2(a) shall be made if such adjustment would result in an increase of the Exercise Price then in effect or a decrease in the number of Warrant Shares. 
  
 (iv) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of
other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $0.01. If
any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any shares
of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration
consists of securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such security on the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the
owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed 

  

 - 7 - 








 
to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or
Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Required Holders. If such parties are unable to reach agreement within ten (10) days
after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Business Days after the tenth day following the Valuation Event by an
independent, reputable appraiser jointly selected by the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be
borne by the Company. 
  
 (v) Record Date. If the Company
takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or
purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or
the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 
  
 (b) Adjustment upon Subdivision or Combination of shares of Common Stock. If the Company at any time on or after the Subscription
Date 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, the Exercise Price in effect immediately prior to such subdivision
will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription Date 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, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased. Any
adjustment under this Section 2(b) shall become effective at the close of business on the date the subdivision or combination becomes effective. 
  

 - 8 - 








 3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company shall declare or make any dividend or other
distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities not addressed by
Section 2, property or options not addressed by Section 2 by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after
the issuance of this Warrant, then, in each such case: 
  
 (a) any Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of shares of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close
of business on such record date, to a price determined by multiplying such Exercise Price by a fraction of which (i) the numerator shall be the Closing Bid Price of a share of Common Stock on the trading day immediately preceding such record
date minus the value of the Distribution (as determined in good faith by the Company’s Board of Directors) applicable to one share of Common Stock, and (ii) the denominator shall be the Closing Bid Price of the shares of Common Stock on
the trading day immediately preceding such record date; and 
  
 (b) the number of Warrant Shares shall be increased to a number of shares equal to the number of shares of Common Stock obtainable immediately prior to the close of business on the record date fixed for the
determination of holders of shares of Common Stock entitled to receive the Distribution multiplied by the reciprocal of the fraction set forth in the immediately preceding paragraph (a); provided that in the event that the Distribution is of shares
of Common Stock (or common stock) (“Other Shares of Common Stock”) of a company whose common shares are traded on a national securities exchange or a national automated quotation system, then the Holder may elect to receive a
warrant to purchase Other Shares of Common Stock in lieu of an increase in the number of Warrant Shares, the terms of which shall be identical to those of this Warrant, except that such warrant shall be exercisable into the number of shares of Other
Shares of Common Stock that would have been payable to the Holder pursuant to the Distribution had the Holder exercised this Warrant immediately prior to such record date and with an aggregate exercise price equal to the product of the amount by
which the exercise price of this Warrant was decreased with respect to the Distribution pursuant to the terms of the immediately preceding paragraph (a) and the number of Warrant Shares calculated in accordance with the first part of this
paragraph (b). 
  
 4. PURCHASE RIGHTS; FUNDAMENTAL
TRANSACTIONS. 
  
 (a) Purchase Rights.
In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the “Purchase Rights”), then, upon exercise of this Warrant, the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights
which the Holder could have acquired if the Holder had held the proportionate number of shares of Common Stock acquirable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) immediately before the date
on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if 

  

 - 9 - 








 
no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase
Rights. 
  
 (b) Fundamental Transactions.
If the Company enters into or is party to a Fundamental Transaction, then the Holder shall have the right to either (A) purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets (including cash) as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of
Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such Fundamental Transaction not taken place or (B) require the repurchase of this Warrant for a purchase price, payable in cash within five (5) business
days after such request, equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of such request. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms
requiring any such successor or surviving entity and Holder to comply with the provisions of this Section 4(b). The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied
without regard to any limitations on the exercise of this Warrant. 
  
 5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of
arrangement, dissolution, issue or sale of securities, or any other voluntary action, for the purpose of avoiding or seeking to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out
all the provisions of this Warrant and take all action that is required hereunder to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common
Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable
shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the SPA Warrants are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock,
solely for the purpose of effecting the exercise of the SPA Warrants, 120% (or such lesser amount limited by the SEC) of the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of the SPA Warrants then
outstanding (without regard to any limitations on exercise). 
  
 6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be
deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a
shareholder 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 such Person is then entitled to receive upon the due exercise of this Warrant. In 

  

 - 10 - 








 
addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this
Warrant or otherwise) or as a shareholder of the Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices and other information given to the shareholders of the Company generally,
contemporaneously with the giving thereof to its shareholders. 
  
 7. REISSUANCE OF WARRANTS. 
  
 (a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance
with Section 7(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less then the total number of Warrant Shares then underlying this Warrant is being
transferred, a new Warrant (in accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred. 
  
 (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of
mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant Shares then underlying this Warrant.

  
 (c) Exchangeable for Multiple
Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase the
number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no
Warrants for fractional shares of Common Stock shall be given. 
  
 (d) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall
represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 7(a) or Section 7(c), the Warrant Shares
designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant),
(iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant. 
  
 8. NOTICES. Whenever notice is required to be given under this
Warrant, unless otherwise provided herein, such notice shall be given in accordance with Section 9(f) of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written 

  

 - 11 - 








 
notice of all actions taken pursuant to this Warrant, including in reasonable detail a description of such action and the reason therefore. Without limiting
the generality of the foregoing, the Company will give written notice to the Holder (i) promptly after any adjustment of the Exercise Price, setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at
least ten days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options,

 9. AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant may be amended and the Company may take any action
herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Required Holders; provided that no such action may increase the exercise price of any SPA Warrant or
decrease the number of shares or class of stock obtainable upon exercise of any SPA Warrant without the written consent of the Holder. No such amendment shall be effective to the extent that it applies to less than all of the holders of the SPA
Warrants then outstanding. 
  
 10. SEVERABILITY. If any
provision of this Warrant or the application thereof becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of the terms of this Warrant will continue in full force and effect. 
  
 11. GOVERNING LAW. This Warrant shall be governed by and construed and
enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three Business Days of such disputed
determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two Business Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable investment bank

Company’s independent, outside accountant. The Company shall cause, at the expense of the prevailing party, the investment bank or the accountant, as
the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or

actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such
breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach,
without the necessity of showing economic loss and without any bond or other security being required.
