 2. EXERCISE 
  

	(a)	Method of Exercise. This Warrant may be exercised in whole or in part (but not as to a fractional share of Common Stock), at any time and from time to time during the
Exercise Period, by the Warrant Holder by surrender of this Warrant, with the form of exercise attached hereto as Exhibit A completed and duly executed by the Warrant Holder (the Exercise Notice), to the Company at the address set
forth in Section 10.4 of the Stock Purchase Agreement, accompanied by payment of the Exercise Price multiplied by the number of Warrant Shares for which this Warrant is being exercised (the Aggregate Exercise Price). The latter of
the date on which the Exercise Notice or payment of the Exercise Price (unless this Warrant is exercised in accordance with Section 2(c) below) is received by the Company in accordance with this clause (a) shall be deemed an
“Exercise Date”. In the event this Warrant is exercised in accordance with Section 2(c) below, the date on which the Exercise Notice is received by the Company in accordance with this clause (a) shall be deemed an
“Exercise Date”. All partial exercises shall first be credited against the Baseline Amount, and following a partial exercise, further exercises shall be effected by subsequent delivery of one or more Exercise Notices.

  

	(b)	Payment of Aggregate Exercise Price. Subject to paragraph (c) below, payment of the Aggregate Exercise Price shall be made by wire transfer of immediately available
funds to an account designated by the Company. If the amount of the payment received by the Company is less than the Aggregate Exercise Price, the Warrant Holder will be notified of the deficiency and shall make payment in that amount within three
(3) Trading Days. In the event the payment exceeds the Aggregate Exercise Price, the Company will refund the excess to the Warrant Holder within five (5) Trading Days of receipt. 

  

	(c)	Cashless Exercise. The Warrant Holder may in its sole discretion, as an alternative to payment of the Aggregate Exercise Price upon exercise in 

  

 Page 6 

 accordance with paragraph (b) above, elect to effect a cashless exercise by so indicating on the
Exercise Notice and including a calculation of the number of Warrant Shares to be issued upon such exercise in accordance with the terms hereof (a Cashless Exercise). In the event of a Cashless Exercise, the Warrant Holder shall
receive that number of shares of Common Stock determined by (i) multiplying the number of Warrant Shares for which this Warrant is being exercised by the Per Share Warrant Value, and (ii) dividing the product by the average of the Closing
Prices on each of the ten Trading Days immediately preceding the Exercise Date, rounded to the nearest whole share. Upon a cashless exercise of some or all of this Warrant, the number of Warrant Shares remaining available for purchase hereunder
shall be reduced by the number of Warrant Shares exercised in such cashless exercise (which shall be applied first against the Baseline Amount), under the foregoing formula (notwithstanding that number of shares issued to the Warrant Holder upon
such cashless exercise shall be less than the number of Warrant Shares exercised). 
  

	(d)	Variable Amount. The Variable Amount shall continue to be calculated throughout the Exercise Period and, to the extent the Variable Amount increases such that additional
shares of Common Stock become available for exercise hereunder following any prior exercises of the Warrant, the Warrant shall remain exercisable for such additional shares for the remainder of the Exercise Period. The Company shall cooperate with
reasonable requests of the Holder to determine or confirm the number of Warrant Shares purchasable at any time pursuant to the Variable Amount. 

 3. DELIVERY OF WARRANT SHARES 
  

	(a)	Subject to the terms and conditions of this Warrant, as soon as practicable after the exercise of this Warrant in full or in part, and in any event within ten (10) Trading Days
thereafter, the Company at its expense will cause to be issued in the name of and delivered to the Warrant Holder, or as the Warrant Holder may lawfully direct, a certificate or certificates for, or, if and only to the extent the Warrant Shares are
not restricted securities, make deposit with the Depositary Trust Company via book-entry of, the number of validly issued, fully paid and non-assessable Warrant Shares to which the Warrant Holder shall be entitled on such exercise, together with any
other stock or other securities or property (including cash, where applicable) to which the Warrant Holder is entitled upon such exercise in accordance with the provisions hereof. 

  

	(b)	This Warrant may not be exercised as to fractional shares of Common Stock. In the event that the exercise of this Warrant, in full or in part, would result in the issuance of any
fractional share of Common Stock, then in such event the Warrant Holder shall receive the number of shares rounded to the nearest whole share. 

  

 Page 7 

 4. REPRESENTATIONS, WARRANTIES AND COVENANTS
OF THE COMPANY 
  

	(a)	The Warrant Shares, when issued in accordance with the terms hereof, will be duly authorized and, when paid for or issued in accordance with the terms hereof, shall be validly
issued, fully paid and non-assessable. 

  

	(b)	The Company shall take all commercially reasonable action and proceedings as may be required and permitted by applicable law, rule and regulation for the legal and valid issuance of
this Warrant and the Warrant Shares to the Warrant Holder. 

  

	(c)	The Company has authorized and reserved for issuance to the Warrant Holder the requisite number of shares of Common Stock to be issued pursuant to this Warrant. The Company shall at
all times reserve and keep available, solely for issuance and delivery as Warrant Shares hereunder, such shares of Common Stock as shall from time to time be issuable as Warrant Shares. 

  

	(d)	From the date hereof through the last date on which this Warrant is exercisable, the Company shall use commercially reasonable efforts to cause the Common Stock to remain listed or
quoted on the Principal Market. 

  

	(e)	The Company shall make all filings and disclosures necessary under the Securities Act and Exchange Act, and shall make such filings and disclosures in compliance in all material
respects with the Securities Act, Exchange Act, and all regulations therein; provided that any failure by the Company to comply with this Section 4(e) shall be deemed to be a breach of this Warrant if, and only if, such failure would
reasonably be considered material by a stockholder of the Company. 

 5. REPRESENTATIONS, WARRANTIES
AND COVENANTS OF THE INVESTOR 
  

	(a)	The Investor is knowledgeable, sophisticated and experienced in making, and is qualified to make, decisions with respect to investments in securities including the Warrant and the
Warrant Shares issuable upon exercise of the Warrant (the Securities) and has requested, received, reviewed and considered all information it deems relevant in making an informed decision to acquire the Securities.

  

	(b)	The Investor is acquiring the Securities for its own account for investment only and with no present intention of distributing any of such Securities, or any arrangement or
understanding with any other persons regarding the distribution of such Securities within the meaning of Section 2(11) of the Securities Act. 

  

	(c)	The Investor will not, directly or indirectly, offer or Transfer (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Securities except in
compliance with this Warrant, the Securities Act, applicable state securities laws and the respective rules and regulations promulgated thereunder. 

  

 Page 8 

	(d)	The Investor is an “accredited investor” within the meaning of Regulation D under the Securities Act. The Investor understands that its acquisition of the Securities has
not been registered under the Securities Act or registered or qualified under any state securities laws in reliance on specific exemptions therefrom, which exemptions may depend upon, among other things, the bona fide nature of the Investor’s
investment intent as expressed herein. 

 6. ADJUSTMENTS 
 The Exercise Price and the number of Warrant Shares issuable upon exercise of the Warrant, shall be subject to adjustment from time to time upon the happening of certain events as follows: 
  

	(a)	Reclassification, Consolidation, Merger, Mandatory Share Exchange, Sale or Transfer. 

  

	 	(i)	Upon the occurrence of and as a condition to the Company’s ability to cause any Adjustment Event while this Warrant is unexpired and not exercised in full, the Warrant Holder
may in its sole discretion require the Company, or any successor or purchasing corporation, as the case may be, without payment of any additional consideration therefor, to execute and deliver to the Warrant Holder a new warrant which shall be
exercisable by the Warrant Holder upon terms not less favorable to the Warrant Holder than those then applicable to this Warrant (a New Warrant) and upon exercise of the New Warrant, the Warrant Holder shall receive in lieu of each
share of Common Stock theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money or property receivable upon such Adjustment Event by the holder of one share of Common Stock issuable upon
exercise of this Warrant had this Warrant been exercised immediately prior to such Adjustment Event. Such new Warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this
Section 6. Prior to such request for a New Warrant, this Warrant shall be exercisable for such number of shares for which the New Warrant would be exercisable. 

  

	 	(ii)	In the event of an Excluded Merger or Sale in which the surviving, successor or purchasing Person does not agree to assume the obligations under this Warrant, the Company shall
deliver a notice to the Warrant Holder at least 10 days before the consummation of such Excluded Merger or Sale and the Warrant Holder may exercise this Warrant at any time before the consummation of such Excluded Merger or Sale (and such exercise
may be made contingent upon the consummation of such Excluded Merger or Sale). Any portion of this Warrant that has not been exercised before consummation of such Excluded Merger or Sale shall terminate and expire, and shall no longer be
outstanding. 

  

 Page 9 

	(b)	Subdivision of Shares. If the Company, at any time while this Warrant is unexpired and not exercised in full, shall subdivide its Common Stock (a Subdivision),
then as of the effective date of such Subdivision, or, if the Company shall take a record of holders of its Common Stock for the purpose of so subdividing, as of such record date, whichever is earlier, (i) the Exercise Price shall be adjusted
by dividing the Exercise Price by the Warrant Adjustment Factor applicable to such Subdivision, and (ii) the number of Warrant Shares for which this Warrant is exercisable at such time shall be adjusted by multiplying the number of Warrant
Shares for which this Warrant is exercisable at such time by the Warrant Adjustment Factor applicable to such Subdivision. 

  

	(c)	Combination of Shares. If the Company, at any time while this Warrant is unexpired and not exercised in full, shall combine its Common Stock (a Combination),
then as of the effective date of such Combination, or, if the Company shall take a record of holders of its Common Stock for the purpose of so combining, as of such record date, whichever is earlier, (i) the Exercise Price shall be adjusted by
dividing the Exercise Price by the Warrant Adjustment Factor applicable to such Combination, and (ii) the number of Warrant Shares for which this Warrant is exercisable at such time shall be adjusted by multiplying the number of Warrant Shares
for which this Warrant is exercisable at such time by the Warrant Adjustment Factor applicable to such Combination. 

  

	(d)	Stock Dividends. If the Company, at any time while this Warrant is unexpired and not exercised in full, shall pay a Stock Dividend, then as of the date the Company shall take
a record of the holders of its Common Stock for the purpose of receiving such dividend or other distribution (or if no such record is taken, as at the date of such payment or other distribution), (i) the Exercise Price shall be adjusted by
dividing the Exercise Price by the Warrant Adjustment Factor applicable to such Stock Dividend, and (ii) the number of Warrant Shares for which this Warrant is exercisable at such time shall be adjusted by multiplying the number of Warrant
Shares for which this Warrant is exercisable at such time by the Warrant Adjustment Factor applicable to such Stock Dividend; provided that the provisions of this subsection (d) shall not apply under any of the circumstances for which an
adjustment is provided in subsections (a),(b), or (c). 

  

	(e)	Liquidating Dividends, Etc. If the Company, at any time while this Warrant is unexpired and not exercised in full, makes a Liquidating Dividend, then the Warrant Holder shall
be entitled to receive upon exercise of this Warrant in addition to the Warrant Shares receivable in connection therewith, and without payment of any consideration other than the Exercise Price, a Liquidating Dividend Adjustment Amount, and an
appropriate provision therefor shall be made a part of any such Liquidating Dividend. The value of a Liquidating Dividend that is paid other than in cash shall be determined in good faith by the Board of Directors of the Company. Notwithstanding the
foregoing, in the event of a proposed Liquidating Dividend made in respect of the sale of all or substantially all of the Company’s assets, the Company shall deliver a notice to 

  

 Page 10 

 the Warrant Holder at least 10 days before the consummation of such event, the Warrant Holder may
exercise this Warrant at any time before the consummation of such event (and such exercise may be made contingent upon the consummation of such event), and any portion of this Warrant that has not been exercised before consummation of such event
shall terminate and expire, and shall no longer be outstanding. 
  

	(f)	Price-Based-Antidilution. 

  

	 	(i)	If at any time or from time to time after the date hereof, the Company issues or sells, or is deemed by the express provisions of this Section 6(f) to have issued or sold,
Additional Shares of Common Stock other than as provided in Sections 6(a)-(e) above, for an Effective Price less than the lower of (i) the Reference Price or (ii) the then-effective Exercise Price (such lower amount, the Trigger
Price), then and in each such case, the then effective Exercise Price shall be reduced, as of the opening of business on the date of such issue or sale, to a price determined in accordance with the following formula:

  

					
	A = B x	 	[C + (D/E)]	 	
		 	    [C + F]	 	

 For the purposes of this Section 6(f)(i) and Section 6(f)(vii), the following
definitions shall apply: 
  

	 	•	 	A = the Exercise Price in effect immediately after such issue or sale of Additional Shares of Common Stock. 

  

	 	•	 	B = the Exercise Price in effect immediately prior to such issue or sale of Additional Shares of Common Stock. 

  

	 	•	 	C = the number of shares of Common Stock Outstanding (as defined in Section 6(f)(ii) below) immediately prior to such issue or sale of Additional Shares of Common
Stock. 

  

	 	•	 	D = the Aggregate Consideration received in exchange for such Additional Shares of Common Stock. 

  

	 	•	 	E = the Trigger Price. 

  

	 	•	 	F = the number of such Additional Shares of Common Stock so issued or sold. 

  

	 	(ii)	For the purposes of Section 6(f)(i), the number of shares of Common Stock deemed to be outstanding (Common Stock Outstanding) as of a given date shall be the sum
of (A) the number of shares of Common Stock outstanding, plus (B) the number of shares of Common Stock into which 

  

 Page 11 

 the then outstanding Convertible Notes could be converted if fully converted on the day immediately
preceding the given date, plus (C) the number of Warrant Shares which are issuable upon the exercise of the Warrant on the day immediately preceding the given date. 
  

	 	(iii)	No adjustment shall be made to the Exercise Price under this Section 6(f) in an amount less than one cent per share. Any adjustment required by this Section 6(f) shall be
rounded to the nearest one cent ($0.01) per share. Any adjustment otherwise required by this Section 6(f) that is not required to be made due to the preceding two sentences shall be included in any subsequent adjustment to the Exercise Price.

  

	 	(iv)	For the purpose of making any adjustment required under this Section 6(f), the aggregate consideration received by the Company for any issue or sale of securities (the
Aggregate Consideration) shall be defined as: (A) to the extent it consists of cash, be computed at the gross amount of cash received by the Company before deduction of any underwriting or similar commissions, compensation or
concessions paid or allowed by the Company in connection with such issue or sale and without deduction of any expenses payable by the Company, (B) to the extent it consists of property other than cash, be computed at the fair value of that
property as determined in good faith by the Board, and (C) if Additional Shares of Common Stock, Convertible Securities or rights or options to purchase either Additional Shares of Common Stock or Convertible Securities are issued or sold
together with other stock or securities or other assets of the Company for a consideration which covers both, be computed as the portion of the consideration so received that may be reasonably determined in good faith by the Board (in a manner
consistent with its comparable activities, such as valuing stock options for accounting purposes) to be allocable to such Additional Shares of Common Stock, Convertible Securities or rights or options. 

  

	 	(v)	For the purpose of the adjustment required under this Section 6(f), if the Company issues or sells (A) capital stock, options, warrants, purchase rights or other
securities convertible into, Additional Shares of Common Stock, other than the Rights (such convertible stock or securities being herein referred to as Convertible Securities), or (B) rights (other than the Rights) or options for
the purchase of Additional Shares of Common Stock or Convertible Securities and if the Effective Price of such Additional Shares of Common Stock is less than the Exercise Price, in each case the Company shall be deemed to have issued at the time of
the issuance of such rights or options or Convertible Securities the maximum number of Additional Shares of Common Stock issuable upon exercise or conversion thereof and to have received as consideration for the issuance of such shares an amount
equal to the total amount of the consideration, if 

  

 Page 12 

 any, received by the Company for the issuance of such rights or options or Convertible Securities plus:

  

	 	(A)	in the case of such rights or options, the minimum amounts of consideration, if any, payable to the Company upon the exercise of such rights or options; and

  

	 	(B)	in the case of Convertible Securities, the minimum amounts of consideration, if any, payable to the Company upon the conversion thereof (other than by cancellation of liabilities or
obligations evidenced by such Convertible Securities); provided that if the minimum amounts of such consideration cannot be ascertained, but are a function of anti-dilution or similar protective clauses, the Company shall be deemed to have
received the minimum amounts of consideration without reference to such clauses. 

  

	 	(C)	If the minimum amount of consideration payable to the Company upon the exercise or conversion of rights, options or Convertible Securities is reduced over time or on the occurrence
or non-occurrence of specified events other than by reason of antidilution or similar protective adjustments, the Effective Price shall be recalculated using the figure to which such minimum amount of consideration is reduced; provided
however, that if the minimum amount of consideration payable to the Company upon the exercise or conversion of such rights, options or Convertible Securities is subsequently increased, the Effective Price shall be again recalculated using the
increased minimum amount of consideration payable to the Company upon the exercise or conversion of such rights, options or Convertible Securities. 

  

	 	(D)	No further adjustment of the Exercise Price, as adjusted upon the issuance of such rights, options or Convertible Securities, shall be made as a result of the actual issuance of
Additional Shares of Common Stock or the exercise of any such rights or options or the conversion of any such Convertible Securities. If any such rights or options or the conversion privilege represented by any such Convertible Securities shall
expire without having been exercised, the Exercise Price as adjusted upon the issuance of such rights, options or Convertible Securities shall be subsequently adjusted to the Exercise Price which would have been in effect had an adjustment been made
on the basis that the only Additional Shares of Common Stock so issued were the Additional Shares of Common Stock, if any, actually issued or sold on the exercise of such rights or options or rights of conversion of such Convertible Securities, and
such Additional Shares of Common Stock, if any, were issued or sold for the consideration actually received by the 

  

 Page 13 

 Company upon such exercise, plus the consideration, if any, actually received by the Company for the
granting of all such rights or options, whether or not exercised, plus the consideration received for issuing or selling the Convertible Securities actually converted, plus the consideration, if any, actually received by the Company (other than by
cancellation of liabilities or obligations evidenced by such Convertible Securities) on the conversion of such Convertible Securities. 
  

	 	(vi)	For the purpose of making any adjustment to the Exercise Price under this Section 6(f), Additional Shares of Common Stock shall mean all shares of Common Stock
issued by the Company or deemed to be issued pursuant to this Section 6(f), other than: 

  

	 	(A)	shares of Common Stock issued upon conversion of the Convertible Notes; 

  

	 	(B)	shares of Common Stock or Convertible Securities issued after the date hereof to employees, officers or directors of, or consultants to, the Company or any subsidiary pursuant to
stock purchase or stock option plans or other arrangements that are approved by the Board (provided that such consultants receive no more than 75,000 shares of Common Stock in aggregate per calendar year and the issuance of such shares to
such consultants shall be for services and in amounts that are consistent with past issuances); 

  

	 	(C)	shares of Common Stock issued pursuant to the exercise of Convertible Securities outstanding as of the date hereof, including the Warrant; or 

  

	 	(D)	shares of Common Stock or Convertible Securities issued in connection with any stock split, stock dividend or recapitalization by the Company. 

 References to Common Stock in the sub-clauses of this Section 6(f) shall mean all shares of Common Stock issued by the Company or deemed to be
issued pursuant to this Section 6(f). 
  

	 	(vii)	The Effective Price shall mean the price at which Additional Shares of Common Stock are issued or sold and shall be determined in accordance with the following
formula: 

 Effective Price = (D)/(F) 
 where D and F have the meaning given them in Section 6(f)(i) above. 
  

 Page 14 

	 	(viii)	In the event that the number of shares of Additional Shares of Common Stock or the Effective Price cannot be ascertained at the time of issuance, such Additional Shares of Common
Stock shall be deemed issued immediately upon the occurrence of the first event that makes such number of shares or the Effective Price, as applicable, ascertainable. 

  

	 	(ix)	Upon any reduction of the Exercise Price pursuant to the provisions of this Section 6(f), the number of Warrant Shares constituting the Baseline Amount on the date of the event
triggering this Section 6(f) shall be increased by the proportion equal to B divided by the A (as those terms are defined in Section 6(f)(i) above. 

 7. NOTICE OF ADJUSTMENTS 
 Whenever the Exercise Price or number of
Warrant Shares shall be adjusted pursuant to Section 6 hereof, the Company shall promptly prepare a certificate signed by its Chief Executive Officer or Chief Financial Officer setting forth in reasonable detail the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis on which the Company’s Board of Directors made any determination hereunder), and the Exercise Price and number of
Warrant Shares purchasable at that Exercise Price after giving effect to such adjustment, and shall promptly cause copies of such certificate to be sent by overnight courier to the Warrant Holder. 
 8. NO IMPAIRMENT 
 The Company will not,
by amendment of its Certificate of Incorporation or Bylaws or through any reorganization, transfer of assets, consolidation, merger, dissolution or issue or sale of securities, 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 Warrant Holder against impairment.
Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any Warrant Shares above the amount payable therefor on such exercise, and (b) will take all such action as may be reasonably necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares on the exercise of this Warrant. 
 9.
RIGHTS AS STOCKHOLDER 
 Except as set forth in Section 6 above, prior to the exercise of this Warrant,
the Warrant Holder shall not be entitled to any rights as a stockholder of the Company with respect to the Warrant Shares, including (without limitation) the right to vote such shares, receive dividends or other distributions thereon or be notified
of stockholder meetings.
