this Warrant, upon the request of the Holder acknowledge in writing its continuing obligation to afford to such holder any rights to which such holder shall continue to be entitled after such exercise in accordance with the provisions of this

appointed as trustee for the Holder pursuant to Subsection 3.2, such bank or trust company shall have all the powers and duties of a warrant agent (as hereinafter described) and shall accept, in its own name for the account of the Company or such
successor person as may be entitled thereto, all amounts otherwise payable to the Company or such successor, as the case may be, on exercise of this Warrant pursuant to this Section 1. 
 2. Procedure for Exercise. 
 2.1.
Delivery of Stock Certificates, Etc., on Exercise. The Company agrees that the shares of Common Stock purchased upon exercise of this Warrant shall be deemed to be issued to the Holder as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been surrendered and payment shall have been made for such shares in accordance herewith. As soon as practicable after the exercise of this Warrant in full or in part, and in any event within
three (3) business days thereafter, the Company at its expense (including the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder, or as such holder (upon payment by such holder of any
applicable transfer taxes) may direct in compliance with applicable securities laws, a certificate or certificates for the number of duly and validly issued, fully paid and nonassessable shares of Common Stock (or Other Securities) to which such
holder shall be entitled on such exercise, plus, in lieu of any fractional share to which such holder would otherwise be entitled, cash equal to such fraction multiplied by the then Fair Market Value of one full share, together with any other stock
or other securities and property (including cash, where applicable) to which such holder is entitled upon such exercise pursuant to Section 1 or otherwise. 
 2.2. Exercise. 
 (a) Payment may be made either (i) in cash or by certified or
official bank check payable to the order of the Company equal to the applicable aggregate Exercise Price, (ii) by delivery of this Warrant, or shares of Common Stock and/or Common Stock receivable upon exercise of this Warrant in accordance
with the formula set forth in subsection (b) below, or (iii) by a combination of any of the foregoing methods, for the number of Common Shares specified in such Exercise Notice (as such exercise number shall be adjusted to reflect any
adjustment in the total number of shares of Common Stock issuable to the Holder per the terms of this Warrant) and the Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully-paid and non-assessable shares
of Common Stock (or Other Securities) determined as provided herein. 
 (b) Notwithstanding any provisions herein to the
contrary, if the Fair Market Value of one share of Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant for cash, the Holder may elect to receive shares equal to the
value (as determined below) of this Warrant (or the portion thereof being exercised) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Exercise Notice in which event the Company shall issue to
the Holder a number of shares of Common Stock computed using the following formula: 
  

			
	X =	  	Y(A-B)
		  	     A

  

			
	Where X =	  	the number of shares of Common Stock to be issued to the Holder

  

 3 









			
	Y =	  	the number of shares of Common Stock purchasable under this Warrant or, if only a portion of this Warrant is being exercised, the portion of this Warrant being exercised (at the date of such
calculation)
		
	A =	  	the Fair Market Value of one share of the Company’s Common Stock (at the date of such calculation)
		
	B =	  	the Exercise Price per share (as adjusted to the date of such calculation)

 3. Effect of Reorganization, Etc.; Adjustment of Exercise Price. 
 3.1. Reorganization, Consolidation, Merger, Etc. In case at any time or from time to time, the Company shall (a) effect a reorganization,
(b) consolidate with or merge into any other person, or (c) transfer all or substantially all of its properties or assets to any other person under any plan or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and adequate provision shall be made by the Company whereby the Holder, on the exercise hereof as provided in Section 1 at any time after the consummation of such
reorganization, consolidation or merger or the effective date of such dissolution, as the case may be, shall receive, in lieu of the Common Stock (or Other Securities) issuable on such exercise prior to such consummation or such effective date, the
stock and other securities and property (including cash) to which such holder would have been entitled upon such consummation or in connection with such dissolution, as the case may be, if such holder had so exercised this Warrant, immediately prior
thereto, all subject to further adjustment thereafter as provided in Section 4. 
 3.2. Dissolution. In the event of any
dissolution of the Company following the transfer of all or substantially all of its properties or assets, the Company, concurrently with any distributions made to holders of its Common Stock, shall at its expense deliver or cause to be delivered to
the Holder the stock and other securities and property (including cash, where applicable) receivable by the Holder pursuant to Section 3.1, or, if the Holder shall so instruct the Company, to a bank or trust company specified by the Holder and
having its principal office in New York, NY as trustee for the Holder (the “Trustee”). 
 3.3. Continuation of Terms. Upon
any reorganization, consolidation, merger or transfer (and any dissolution following any transfer) referred to in this Section 3, this Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of
stock and other securities and property receivable on the exercise of this Warrant after the consummation of such reorganization, consolidation or merger or the effective date of dissolution following any such transfer, as the case may be, and shall
be binding upon the issuer of any such stock or other securities, including, in the case of any such transfer, the person 
  

 4 








 acquiring all or substantially all of the properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4. In the event this Warrant does not continue in full force and effect after the consummation of the transactions described in this Section 3, then the Company’s
securities and property (including cash, where applicable) receivable by the Holder will be delivered to the Holder or the Trustee as contemplated by Section 3.2. 
 4. Extraordinary Events Regarding Common Stock. In the event that the Company shall (a) issue additional shares of the Common Stock as a dividend or other distribution on outstanding Common Stock or any
preferred stock issued by the Company (b) subdivide its outstanding shares of Common Stock, or (c) combine its outstanding shares of the Common Stock into a smaller number of shares of the Common Stock, then, in each such event, the
Exercise Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Exercise Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such event
and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Exercise Price then in effect. The Exercise Price, as so adjusted, shall be
readjusted in the same manner upon the happening of any successive event or events described herein in this Section 4. The number of shares of Common Stock that the Holder shall thereafter, on the exercise hereof as provided in Section 1,
be entitled to receive shall be adjusted to a number determined by multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section 4) be issuable on such exercise by a fraction of which (a) the
numerator is the Exercise Price that would otherwise (but for the provisions of this Section 4) be in effect, and (b) the denominator is the Exercise Price in effect on the date of such exercise (taking into account the provisions of this
Section 4). 
 5. Certificate as to Adjustments. In each case of any adjustment or readjustment in the shares of Common Stock (or
Other Securities) issuable on the exercise of this Warrant, the Company at its expense will promptly cause its Chief Financial Officer or other appropriate designee to compute such adjustment or readjustment in accordance with the terms of this
Warrant and prepare a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a statement of (a) the consideration received or receivable by the
Company for any additional shares of Common Stock (or Other Securities) issued or sold or deemed to have been issued or sold, (b) the number of shares of Common Stock (or Other Securities) outstanding or deemed to be outstanding, and
(c) the Exercise Price and the number of shares of Common Stock to be received upon exercise of this Warrant, in effect immediately prior to such adjustment or readjustment and as adjusted or readjusted as provided in this Warrant. The Company
will forthwith mail a copy of each such certificate to the Holder and any Warrant agent of the Company (appointed pursuant to Section 11 hereof). 
 6. Reservation of Stock, Etc., Issuable on Exercise of Warrant. The Company will at all times reserve and keep available, solely for issuance and delivery on the exercise of this Warrant, shares of Common Stock
(or Other Securities) from time to time issuable on the exercise of this Warrant.

 7. Assignment; Exchange of Warrant. Subject to compliance with applicable securities laws, this
Warrant, and the rights evidenced hereby, may be transferred by any registered holder hereof (a “Transferor”) in whole or in part. On the surrender for exchange of this Warrant, with the Transferor’s endorsement in the form of Exhibit
B attached hereto (the “Transferor Endorsement Form”) and together with evidence reasonably satisfactory to the Company demonstrating compliance with applicable securities laws, which shall include, without limitation, the provision of a
legal opinion from the Transferor’s counsel (at the Company’s expense) that such transfer is exempt from the registration requirements of applicable securities laws, the Company at its expense (but with payment by the Transferor of any
applicable transfer taxes) will issue and deliver to or on the order of the Transferor thereof a new Warrant of like tenor, in the name of the Transferor and/or the transferee(s) specified in such Transferor Endorsement Form (each a
“Transferee”), calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face or faces of the Warrant so surrendered by the Transferor. 
 8. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this
Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and
cancellation of this Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor. 
 9.
Registration Rights. The Holder has been granted certain registration rights by the Company. These registration rights are set forth in a Registration Rights Agreement entered into by the Company and Holder dated as of the date hereof, as the
same may be amended, modified and/or supplemented from time to time. 
 10. Maximum Exercise. Notwithstanding anything herein to the
contrary, in no event shall the Holder be entitled to exercise any portion of this Warrant in excess of that portion of this Warrant upon exercise of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and
its Affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unexercised portion of the Warrant or the unexercised or unconverted portion of any other security of the Holder subject to a
limitation on conversion analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the exercise of the portion of this Warrant with respect to which the determination of this proviso is being
made, would result in beneficial ownership by the Holder and its Affiliates of any amount greater than 4.99% of the then outstanding shares of Common Stock (whether or not, at the time of such exercise, the Holder and its Affiliates beneficially own
more than 4.99% of the then outstanding shares of Common Stock). As used herein, the term “Affiliate” means any person or entity that, directly or indirectly through one or more intermediaries, controls or is controlled by or is under
common control with a person or entity, as such terms are used in and construed under Rule 144 under the Securities Act. For purposes of the proviso to the second preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such proviso. The limitations set forth herein (x) may be waived by the Holder upon
provision of no less than sixty one (61) days prior notice to the Company and (y) shall automatically become null 
  

 6 








 and void following notice to the Company upon the occurrence and during the continuance of an Event of Default (as
defined in the Note referred to in the Note and Warrant Purchase Agreement dated as of the date hereof among the Holder and the Company (as amended, modified, restated and/or supplemented from time to time, the “Purchase Agreement”)).

 11. Warrant Agent. The Company may, by written notice to the each Holder of the Warrant, appoint an agent for the purpose of
issuing Common Stock (or Other Securities) on the exercise of this Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section 7, and replacing this Warrant pursuant to Section 8, or any of the foregoing, and thereafter
any such issuance, exchange or replacement, as the case may be, shall be made at such office by such agent. 
 12. Transfer on the
Company’s Books. Until this Warrant is transferred on the books of the Company, the Company may treat the Holder hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary. 
 13. Notices, Etc. All notices and other communications from the Company to the Holder shall be mailed by first class registered or certified mail,
postage prepaid, at such address as may have been furnished to the Company in writing by such holder or, until any such holder furnishes to the Company an address, then to, and at the address of, the last Holder who has so furnished an address to
the Company. 
 14. Miscellaneous. This Warrant and any term hereof may be changed, waived, discharged or terminated only by an
instrument in writing signed by the party against which enforcement of such change, waiver, discharge or termination is sought. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS. ANY ACTION BROUGHT CONCERNING THE TRANSACTIONS CONTEMPLATED BY THIS WARRANT SHALL BE BROUGHT ONLY IN THE STATE COURTS OF NEW YORK OR IN THE FEDERAL COURTS LOCATED IN THE STATE OF NEW YORK; PROVIDED, HOWEVER, THAT THE
HOLDER MAY CHOOSE TO WAIVE THIS PROVISION AND BRING AN ACTION OUTSIDE THE STATE OF NEW YORK. The individuals executing this Warrant on behalf of the Company agree to submit to the jurisdiction of such courts and waive trial by jury. The prevailing
party shall be entitled to recover from the other party its reasonable attorneys’ fees and costs. In the event that any provision of this Warrant is invalid or unenforceable under any applicable statute or rule of law, then such provision shall
be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or
enforceability of any other provision of this Warrant. The headings in this Warrant are for purposes of reference only, and shall not limit or otherwise affect any of the terms hereof. The invalidity or unenforceability of any provision hereof shall
in no way affect the validity or enforceability of any other provision hereof. The Company acknowledges that legal counsel participated in the preparation of this Warrant and, therefore, stipulates that the rule of construction that ambiguities are
to be resolved against the drafting party shall not be applied in the interpretation of this Warrant to favor any party against the other party.
