appointment of Security Agent as its agent hereunder, (b) to confirm that the Security Agent shall have the authority to act as the exclusive agent of such Person for the enforcement of any provisions of this Agreement against the Company, the
exercise of remedies hereunder and the giving or withholding of any consent or approval hereunder relating to any Collateral or the Company’s obligations with respect thereto, (c) to agree that it shall not take any action to enforce any
provisions of this Agreement against the Company, to exercise any remedy hereunder or to give any consents or approvals hereunder except as expressly provided in this Agreement or in the Notes and (d) to agree to be bound by the terms of this
Agreement. The appointment of the Security Agent shall continue until revoked in writing by a Majority in Interest, at which time a Majority in Interest shall appoint a new Security Agent. The Security Agent may perform any of its duties hereunder
by or through its agents or employees. 
 Section 8.2 Nature of Duties. The Security Agent shall have no
duties or responsibilities except those expressly set forth in this Agreement. Neither the Security Agent nor any of its partners, members, shareholders, officers, directors, employees or agents shall be liable for any action taken or omitted
by it as such under the Agreement or in connection herewith, be responsible for the consequence of any oversight or error of judgment or answerable for any loss, unless caused solely by its or their gross negligence or willful misconduct as
determined by a final judgment (not subject to further appeal) of a court of competent jurisdiction. The duties of the Security Agent shall be mechanical and administrative in nature; the Security Agent shall not have by reason of the Agreement
or any other Transaction Document a fiduciary relationship in respect of the Company or any Secured Party; and nothing in the Agreement or any other Transaction Document, expressed or implied, is intended to or shall be so construed as to impose
upon the Agent any obligations in respect of the Agreement or any other Transaction Document except as expressly set forth herein and therein. 
 Section 8.3 Lack of Reliance on the Security Agent. Independently and without reliance upon the Security Agent, each Secured Party, to the extent it deems appropriate, has made and shall
continue to make (i) its own independent investigation of the financial condition and affairs of the Company and its subsidiaries in connection with such Secured Party’s investment in the Company, the creation and continuance of the
Obligations, the transactions contemplated by the Transaction Documents, and the taking or not taking of any action in connection therewith, and (ii) its own appraisal of the creditworthiness of the Company and its subsidiaries, and of the
value of the Collateral from time to time, and the Security Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Secured Party with any credit, market or other information with respect thereto,
whether coming into its possession before any Obligations are incurred or at any time or times thereafter. The Security Agent shall not be responsible to the Company or any Secured Party for any recitals, statements, information,
representations or warranties herein or in any document, certificate or other writing delivered in connection herewith, or for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectibility, priority or sufficiency
of the Agreement or any other Transaction Document, or for the financial condition of the Company or the value of any of the Collateral, or be required to make any inquiry concerning either the performance or observance of any of the terms,
provisions or conditions of the Agreement or any other Transaction Document, or the financial condition of the Company, or the value of any of the Collateral, or the existence or possible existence of any default or Event of Default under the
Agreement, the Notes or any of the other Transaction Documents.

 Section 8.4 Certain Rights of the Security Agent. The Security Agent shall have
the right to take any action with respect to the Collateral permitted by this Agreement, on behalf of all of the Secured Parties. To the extent practical, the Security Agent shall request instructions from the Secured Parties with respect to
any material act or action (including failure to act) in connection with the Agreement or any other Transaction Document, and shall be entitled to act or refrain from acting in accordance with the instructions of a Majority in Interest; if such
instructions are not provided despite the Security Agent’s request therefor, the Security Agent shall be entitled to refrain from such act or taking such action, and if such action is taken, shall be entitled to appropriate indemnification from
the Secured Parties in respect of actions to be taken by the Security Agent; and the Security Agent shall not incur liability to any person or entity by reason of so refraining. Without limiting the foregoing, (a) no Secured Party shall
have any right of action whatsoever against the Security Agent as a result of the Security Agent acting or refraining from acting hereunder in accordance with the terms of the Agreement or any other Transaction Document, and the Company shall have
no right to question or challenge the authority of, or the instructions given to, the Security Agent pursuant to the foregoing and (b) the Security Agent shall not be required to take any action which the Security Agent believes (i) could
reasonably be expected to expose it to personal liability or (ii) is contrary to this Agreement, the Transaction Documents or applicable law. 
 Section 8.5 Reliance. The Security Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, statement, certificate, telex, teletype
or telecopier message, cablegram, radiogram, order or other document or telephone message signed, sent or made by the proper person or entity, and, with respect to all legal matters pertaining to the Agreement and the other Transaction Documents and
its duties thereunder, upon advice of counsel selected by it and upon all other matters pertaining to this Agreement and the other Transaction Documents and its duties thereunder, upon advice of other experts selected by it. Anything to the
contrary notwithstanding, the Security Agent shall have no obligation whatsoever to any Secured Party to assure that the Collateral exists or is owned by the Company or is cared for, protected or insured or that the liens granted pursuant to the
Agreement have been properly or sufficiently or lawfully created, perfected, or enforced or are entitled to any particular priority. 
 Section 8.6 Indemnification. To the extent that the Security Agent is not reimbursed and indemnified by the Company, the Secured Parties will jointly and severally reimburse and
indemnify the Security Agent, in proportion to their initially purchased respective principal amounts of Notes, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Security Agent in performing its duties hereunder or under the Agreement or any other Transaction Document, or in any way relating to or
arising out of the Agreement or any other Transaction Document except for those determined by a final judgment (not subject to further appeal) of a court of competent jurisdiction to have resulted solely from the Security Agent’s own gross
negligence or willful misconduct. Prior to taking any action hereunder as Security Agent, the Security Agent may require each Secured Party to deposit with it sufficient sums as it determines in good faith is necessary to protect the Security
Agent for costs and expenses associated with taking such action. 
 Section 8.7 Resignation by the Security Agent.

 (a) The Security Agent may resign from the performance of all its functions and duties under the Agreement and the other
Transaction Documents at any time by giving 30 days’ prior written notice (as provided in the Agreement) to the Company and the Secured Parties. Such resignation shall take effect upon the appointment of a successor Security Agent pursuant
to clauses (b) and (c) below. 

  
 12 

 (b) Upon any such notice of resignation, the Secured Parties, acting by a Majority in
Interest, shall appoint a successor Security Agent hereunder. 
 (c) If a successor Security Agent shall not have been so
appointed within said 30-day period, the Security Agent shall then appoint a successor Security Agent who shall serve as Security Agent until such time, if any, as the Secured Parties appoint a successor Security Agent as provided above. If a
successor Security Agent has not been appointed within such 30-day period, the Security Agent may petition any court of competent jurisdiction or may interplead the Company and the Secured Parties in a proceeding for the appointment of a successor
Security Agent, and all fees, including, but not limited to, extraordinary fees associated with the filing of interpleader and expenses associated therewith, shall be payable by the Company on demand. 

Section 8.8 Rights with respect to Collateral. Each Secured Party agrees with all other Secured Parties and the
Security Agent (i) that it shall not, and shall not attempt to, independently exercise any rights with respect to its security interest in the Collateral, whether pursuant to any other agreement or otherwise (other than pursuant to this
Agreement), or take or institute any action against the Security Agent or any of the other Secured Parties in respect of the Collateral or its rights hereunder (other than any such action arising from the breach of this Agreement) and (ii) that
such Secured Party has no other rights with respect to the Collateral other than as set forth in this Agreement and the other Transaction Documents. Upon the acceptance of any appointment as Security Agent hereunder by a successor Security
Agent, such successor Security Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Security Agent and the retiring Security Agent shall be discharged from its duties and obligations
under the Agreement. After any retiring Security Agent’s resignation or removal hereunder as Security Agent, the provisions of the Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it while it was

terminate the Secured Parties’ security interest in the Collateral, subject to any disposition of the Collateral that may have been made by or on behalf of the Secured Parties pursuant to this Agreement. For the purpose of this Agreement, the
Obligations shall be deemed to continue if the Company enters into any bankruptcy or similar proceeding at a time when any amount paid to the Secured Parties could be ordered to be repaid as a preference or pursuant to a similar theory, and shall
continue until it is finally determined that no such repayment can be ordered.

in the proxy statement for the Stockholders’ Meeting such Stockholder’s identity and ownership of Shares and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement and may further file this
Agreement as an exhibit to the filings made by Company with the Securities and Exchange Commission relating to the Proposed Amendments. 
 (j) Severability. If any term or other provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in
full force and effect so long as the economic or legal substance of this Agreement is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the terms of this Agreement remain as
originally contemplated to the fullest extent possible. 
 (k) Confidentiality. In this connection, pending public
disclosure thereof, and so that the Company may rely on the safe harbor provisions of Rule 100(b)(2)(ii) of Regulation FD, each Stockholder, solely in his or its capacity as a Stockholder, hereby agrees not to disclose or discuss such matters with
anyone not a party to this Agreement (other than his or its counsel and advisors, if any) without the prior written consent of the Company, except for disclosures such Stockholder’s counsel advises are necessary in order to comply with any

may be available to Company, upon any such violation, the Company shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means to which they are entitled at law or in equity, without
requiring the posting of any bond or other undertaking.

and other communications under this Agreement shall be in writing and shall be deemed given if (a) delivered to the appropriate address by hand or overnight courier (providing proof of delivery), or (b) sent by facsimile with confirmation

 2. Exercise of
Warrant. 
 (a) Manner of Exercise. 
 (i) Cash Exercise. This Warrant may be exercised, in whole or in part, at any time or from time to time, during the period commencing as of 9:30:01 a.m., New York time, on the Initial Exercise Date
and ending as of 5:30 p.m., New York time, on the Expiration Date (the “Exercise Period”), for                     fully paid and
non-assessable shares of Common Stock (the “Warrant Shares”), for an exercise price per share equal to the Exercise Price, by delivery to the Company at its headquarters, or at such other place as is designated in writing by the
Company, of: 
 (1) a duly executed Notice of Exercise, substantially in the form of Attachment I attached hereto and
incorporated by reference herein; 
 (2) this Warrant; and 

(3) subject to Section 2(a)(ii) below, payment of an amount in cash equal to the product of the Exercise Price multiplied by
the number of Warrant Shares being purchased upon such exercise, with such payment being in the form of a wire transfer of immediately available U.S. funds to an account designated in writing by the Company. 

The date on which the Company receives the Notice of Exercise, this Warrant, and the Exercise Price payable with respect to the Warrant
Shares being purchased shall be deemed to be the date of exercise (the “Date of Exercise”). 
 (ii) Cashless
Exercise. Notwithstanding the provisions of Section 2(a)(i)(3) above (requiring payment by wire transfer), the Company agrees that, unless otherwise prohibited by applicable law, the Holder shall have the right to exercise this
Warrant in full or in part on a cashless basis, computed using the following formula: 
  

									
		 	X	 	=	 	Y (A - B)    	 	
		 		 		 	      A    	 	

 Where: 
 X = The number of Warrant Shares to be issued to the Holder pursuant to this cashless exercise; 
 Y = The number of Warrant Shares in respect of which the net issue election is made; 
 A = The Fair Market Value (as defined below) of one Warrant Share at the time the cashless exercise election is made; and 
 B = The Exercise Price then in effect at the time of such exercise. 
 The term
“Fair Market Value” shall mean, on any given day: (A) if the class of Warrant Shares is exchange-traded, the average of the closing sales prices per share of the class of Warrant Shares for the ten (10) consecutive trading days
ending on the day that is two (2) trading days prior to the applicable date of determination of Fair Market Value; or (B) if the class of Warrant Shares is not listed or admitted to trading on any securities exchange but is regularly
traded in any over-the-counter market, then the 

  
 - 2 -

 
average of the bid and ask prices per share of the class of Warrant Shares for the ten (10) consecutive trading days ending on the day that is two (2) trading days prior to the
applicable date of determination of Fair Market Value; or (C) if the class of Warrant Shares is not traded as described in clauses (A) or (B), then the per share fair market value of the class of Warrant Shares as determined in good faith
by the Company’s Board of Directors. 
 (b) Delivery of Certificates. Subject to the provisions below, upon receipt
of the Notice of Exercise, the Company shall immediately instruct its transfer agent to prepare certificates for the Warrant Shares to be received by the Holder upon such exercise. The Company shall, at its own cost and expense, cause the transfer
agent to deliver such certificates to the Holder (or to such other nominee as may be designated by the Holder) within three Business Days following the Date of Exercise (the “Delivery Period”). 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 as of the Date of Exercise, irrespective of the date such certificates are actually delivered by the transfer agent to
the Holder or are credited to the Holder’s Depository Trust Company (“DTC”) account, as the case may be. If fewer than all of the Warrant Shares purchasable under the Warrant are purchased, the Company will, upon such partial
exercise, execute and deliver to the Holder a new Warrant (dated as of the Issue Date), in the same form and tenor as this Warrant, evidencing that portion of the Warrant not exercised. 

(c) Delivery of Electronic Shares. In lieu of delivering physical certificates representing the Warrant Shares issuable upon
exercise (provided that the transfer agent is participating in the DTC Fast Automated Securities Transfer program and provided further that the Holder provides the transfer agent with information required in order to issue such Warrant Shares to the
Holder electronically), upon the request of the Holder as set forth in the Notice of Exercise, but only if the Warrant Shares may be issued without restrictive legends, the Company shall cause its transfer agent to electronically transmit, within
the Delivery Period, the Warrant Shares issuable upon exercise to the Holder by crediting Holder’s account with DTC through its Deposit Withdrawal Agent Commission system. Any delivery not effected by electronic transmission shall be effected
by delivery of physical certificates. 
 (d) No Fractional Shares. If a fractional share of Warrant Shares would, but for
the provisions of this Section 2(d), be issuable upon exercise of the rights represented by this Warrant, the Company shall (i) round a half share or greater to be delivered to Holder up to the next whole share and (ii) round a
less-than-half share to be delivered to Holder down to the nearest whole share. 
 (e) Buy-In. Notwithstanding anything
else to the contrary contained herein, in addition to any other rights available to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the applicable Warrant Shares
purchased upon exercise hereof or credit the Holder’s balance account with DTC, as applicable, on or before the end of the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company
hereunder), and if after such date the Holder purchases shares of Common Stock to deliver in satisfaction of a sale by the Holder of Warrant Shares that the Holder anticipated receiving from the Company upon exercise of this Warrant (a
“Buy-In”), then the Company shall, within three Business Days after the Holder’s request, (1) pay cash to the Holder the amount by which (x) the Holder’s total purchase price (including commissions, if any) for
the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue, by (B) the price
at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored, or
deliver to the Holder the number of Warrant Shares that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. The Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In, 

  
 - 3 -

 
together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it
hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing the Securities as required pursuant to the
terms hereof. 
 (f) No Charge to Holder Upon Issuance. The issuance of Warrant Shares upon exercise of this Warrant
shall be made without charge to Holder for any issuance tax in respect thereof or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares (other than any transfer taxes resulting from the
issuance of Warrant Shares to any person other than Holder). 
 (g) Reservation of Shares. During the Exercise Period,
the Company shall reserve and keep available out of its authorized but unissued Common Stock such number of Warrant Shares issuable upon the full exercise of this Warrant. All Warrant Shares which are so issuable shall, when issued and upon the
payment of the applicable Exercise Price, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges and not subject to the pre-emptive rights of any holder of Common Stock or any other class or series of
stock of the Company. During the Exercise Period, the Company shall not take any action which would cause the number of authorized but unissued Common Stock to be less than the number of such shares required to be reserved hereunder for issuance
upon exercise of this Warrant. 
 (h) Limitations on Exercises. 

(i) Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by the Holder hereof to the
extent (but only to the extent) that the Holder or any of its affiliates would beneficially own in excess of 9.99% (the “Maximum Percentage”) of the Common Stock. To the extent the above limitation applies, the determination of
whether this Warrant shall be exercisable (vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of which such securities shall be exercisable (as among all such securities owned
by the Holder) shall, subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be). No prior inability to exercise this Warrant pursuant to
this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. For the purposes of this paragraph, beneficial ownership and all determinations and
calculations (including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the Exchange Act. The limitations contained in this paragraph shall apply to a successor
Holder of this Warrant. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding,
including by virtue of any prior conversion or exercise of convertible or exercisable securities into Common Stock. The provisions of this Section 2(h)(i) may be waived by such Holder, at the election of such Holder, upon not less than
61 days’ prior notice to the Company, and the provisions of this Section 2(h)(i) shall continue to apply until such 61st day (or such later date, as determined by such Holder, as may be specified in such notice of waiver).

 (ii) Notwithstanding anything else set forth herein, in no event shall this Warrant be exercisable by the Holder to the
extent that the Holder or any of its affiliates and any other Person whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), would beneficially own in excess of 19.99% of the number of shares of the Company’s Common Stock outstanding at the time of such issuance unless any issuances in excess of the foregoing limitation are approved
by the Company’s common stockholders. 

  
 - 4 -

 3. Adjustments in Certain Events. The number, class, and price of Warrant Shares for which this
Warrant may be exercised are subject to adjustment from time to time upon the happening of certain events as follows: 
 (a)
Subdivisions, Combinations and Other Issuances. If the outstanding shares of the Company’s Common Stock are divided into a greater number of shares, by forward stock split or otherwise, or a dividend in stock is paid on the Common Stock,
then the number of shares of Warrant Shares for which the Warrant is then exercisable will be proportionately increased and the Exercise Price will be proportionately reduced. Conversely, if the outstanding shares of Common Stock are combined into a
smaller number of shares of Common Stock, by reverse stock split or otherwise, then the number of Warrant Shares for which the Warrant is then exercisable will be proportionately reduced and the Exercise Price will be proportionately increased. The
increases and reductions provided for in this Section 3(a) will be made with the intent and, as nearly as practicable, the effect that neither the percentage of the total equity of the Company obtainable on exercise of the Warrants nor
the price payable for such percentage upon such exercise will be affected by any event described in this Section 3(a). 
 (b) Merger, Consolidation, Reclassification, Reorganization, Etc. In case of any change in the Common Stock through merger, consolidation, reclassification, reorganization, partial or complete
liquidation, purchase of all or substantially all the assets of the Company, or other change in the capital structure of the Company, then, as a condition of such change, lawful and adequate provision will be made so that the Holder will have the
right thereafter to receive upon the exercise of the Warrant the kind and amount of shares of stock or other securities or property to which he would have been entitled if, immediately prior to such event, he had held the number of Warrant Shares
obtainable upon the exercise of the Warrant. In any such case, appropriate adjustment will be made in the application of the provisions set forth herein with respect to the rights and interest thereafter of the Holder, to the end that the provisions
set forth herein will thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the exercise of the Warrant. The Company will not permit any change in its capital
structure to occur unless the issuer of the shares of stock or other securities to be received by the Holder, if not the Company, agrees to be bound by and comply with the provisions of this Warrant. 

(c) Notice of Record Date, Etc. In the event the Company shall propose to take any action of the types requiring an adjustment
pursuant to this Section 3 or a dissolution, liquidation or winding up of the Company shall be proposed, the Company shall give notice to Holder as provided in Section 6 below, which notice shall specify the record date, if
any, with respect to any such action and the date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such
effect may be known at the date of such notice) on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or deliverable upon the
exercise of the Warrant. In the case of any action which will require the fixing of a record date, unless otherwise provided in this Warrant, such notice shall be given at least twenty (20) days prior to the date so fixed, and in case of all
other action, such notice shall be given at least thirty (30) days prior to the taking of such proposed action. 
 (d) If
securities of the Company or securities of any subsidiary of the Company are distributed pro rata to holders of Common Stock, such number of securities will be distributed to the Holder or its assignee upon exercise of its rights hereunder as such
Holder or assignee would have been 

  
 - 5 -

 
entitled to if this Warrant had been exercised prior to the record date for such distribution. The provisions with respect to adjustment of the Common Stock provided in this Section 3
will also apply to the securities to which the Holder or its assignee is entitled under this Section 3(d). 
 4. No Rights as a
Stockholder. Nothing contained in this Agreement shall be construed as conferring upon the Holder any rights whatsoever as a stockholder of the Company, either at law or in equity, including without limitation, or Holders the right to vote or to
consent or to receive notice as a stockholder in respect of any meetings of stockholders for the election of directors the right to receive dividends or any other matter. 
 5. Restrictions on Transfer; Legends. 
 (a) Registration or Exemption
Required. Assuming the accuracy of the representations and warranties of the Holder contained in herein, this Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Section 4(2)
of the Securities Act and Regulation D promulgated thereunder and exempt from state registration or qualification under applicable state laws. Neither this Warrant nor the Warrant Shares may be pledged, transferred, sold or assigned except pursuant
to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer
of this Warrant shall not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such transfer (i) that
the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that
such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the holder or transferee execute and deliver to the Company an investment letter in form and substance
acceptable to the Company and (iii) that the transferee be an “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) under the
Securities Act. 
 (b) Representations of Holder. The Holder represents and warrants that he has acquired this Warrant
and will acquire the Warrant Shares for his own account for investment and not with a view to the sale or distribution thereof or the granting of any participation therein, and that he has no present intention of distributing or selling to others
any of such interest or granting any participation therein. The Holder acknowledges that the Warrant and Warrant Shares must be held indefinitely unless a subsequent disposition thereof is registered under the Securities Act or registered or
qualified under any applicable state securities or “blue-sky” laws or is exempt from registration and/or qualification. The Holder has no need for liquidity in its investment in the Company, and is able to bear the economic risk of such
investment for an indefinite period and to afford a complete loss thereof. The Holder is an “accredited investor” as such term is defined in Rule 501 (the provisions of which are known to the Holder) promulgated under the Act. 

(c) Restrictive Legend. The Holder understands that until such time as the Warrant Shares have been registered under the
Securities Act, or otherwise may be sold pursuant to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be
immediately sold, this Warrant and the Warrant Shares, as applicable, shall bear a restrictive legend in substantially the form set forth on the cover page of this Warrant (and a stop-transfer order may be placed against transfer of the certificates
for such securities). 

  
 - 6 -

 (d) Disposition of Warrant or Warrant Shares. With respect to any offer, sale or
other disposition of this Warrant or any Warrant Shares prior to registration of such Warrant Shares, the Holder agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with evidence, reasonably
satisfactory to the Company (which shall include such representation of the transferee regarding investment intent as the Company may request, to the effect that such offer, sale or other disposition may be effected without registration or
qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or such Warrant Shares and indicating whether or not under the Securities Act certificates for this Warrant or Warrant Shares to be
sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably satisfactory evidence, the Company, as
promptly as practicable but no later than seven (7) days after receipt of the written notice, shall notify the Holder that the Holder may sell or otherwise dispose of this Warrant or Warrant Shares, all in accordance with the terms of the
notice delivered to the Company. If the Company determines that the evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly with details thereof after such determination has been
made. Notwithstanding the foregoing, any Warrant Shares may be offered, sold or otherwise disposed of in accordance with Rule 144 under the Act and in compliance with the applicable statutory resale restrictions imposed by state securities
laws, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 and the applicable resale restrictions imposed by state
securities laws have been satisfied. Each certificate representing this Warrant or the Warrant Shares thus transferred shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with such laws, unless
pursuant to an opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions. 

(e) Removal of Restrictive Legends. The certificates evidencing the Warrant Shares shall not contain any legend restricting the
transfer thereof: (A) while a registration statement covering the sale or resale of the Warrant Shares is effective under the Securities Act and such legend removal is permitted under applicable securities laws (including compliance with the
prospectus delivery requirements of the Securities Act), or (B) following any sale of such Warrant Shares pursuant to Rule 144, or (C) if such Warrant Shares are eligible for sale under Rule 144(b)(1), or (D) if such legend is not
required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) and the Company shall have received an opinion of counsel to the Holder in form reasonably
acceptable to the Company to such effect (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal opinion to its transfer agent if required by the transfer agent to effect the issuance of
the Warrant Shares, as applicable, without a restrictive legend or removal of the legend hereunder. The Company agrees that at such time as the Unrestricted Conditions are met, it will, no later than three (3) Trading Days following the
delivery by the Holder to the Company or the transfer agent of a certificate representing Warrant Shares, issued with a restrictive legend, deliver or cause to be delivered to such Holder a certificate (or electronic transfer) representing such
Warrant Shares that is free from all restrictive and other legends. 
 6. Piggyback Registration Rights. 

6.1 Registration. If at any time during the Exercise Period, the Company shall determine to prepare and file with the Commission a
registration statement under the Securities Act of 1933, as amended (the “Securities Act”) relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than
(i) any registration statement (or amendment thereto) filed by the Company but which has not been declared effective on or before the Issue Date; (ii) any registration statement on Form S-3 (or any successor form) filed by the Company for
the purpose of effecting offers and sales of securities on a continuous or delayed basis pursuant to Rule 415(a) (ix) or (x)

  
 - 7 -

 
under the Securities Act; or (iii) a registration statement on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to
be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with the stock option or other employee benefit plans, then the Company shall send to each holder of this Warrant (a
“Holder”) a written notice of such determination and, if within fifteen (15) days after the date of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any
part of such Warrant Shares which such Holder requests to be registered, subject to customary underwriter cutbacks applicable to all holders of registration rights, provided that if at any time after giving written notice of its intention to
register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company
may, at its election, give written notice of such determination to such Holder and, thereupon, (A) in the case of a determination not to register, shall be relieved of its obligation to register any Warrant Shares in connection with such
registration (but not from its obligation to pay expenses in accordance with Section 6.5 hereof), and (B) in the case of a determination to delay registering, shall be permitted to delay registering any Warrant Shares being
registered pursuant to this Section 6.1 for the same period as the delay in registering such other securities. Notwithstanding the foregoing, the Company shall not be required to register any Warrant Shares pursuant to this Section 6.1
that are eligible for resale pursuant to Rule 144(b) promulgated under the Securities Act or that are the subject of a then effective registration statement. For the purpose of the foregoing, inclusion of the Warrant Shares by the Holder in a
registration statement under a condition that the offer and/or sale of such Warrant Shares not commence until a date not to exceed 90 days from the effective date of such registration statement shall be deemed to be in compliance with this
sub-paragraph. 
 6.2 Exceptions. The Company shall have no obligation to include Warrant Shares of any Holder in a
registration statement pursuant to this Section 6, unless and until such Holder (i) in connection with any underwritten offering, agrees to enter into an underwriting agreement, a custody agreement and power of attorney and any other
customary documents required in an underwritten offering all in customary form and containing customary provisions and (ii) regardless of whether such registration is in connection with an underwritten offering, shall have furnished the Company
with all information and statements about or pertaining to such Holder in such reasonable detail and on such timely basis as is reasonably deemed by the Company to be legally required with respect to the preparation of the registration statement.

 6.3 Procedures. The foregoing registration rights shall be contingent on the Holders furnishing the Company with such
appropriate information (relating to the intentions of such Holders) as the Company shall reasonably request in writing. Each Holder agrees to furnish to the Company a completed selling security holder questionnaire in such form as is provided by
the Company to the Holder not less than two Business Days prior to date on which the Company files the registration statement (the “Filing Date”). The Company shall not be required to include the Warrant Shares of a Holder in a
registration statement for any Holder who fails to furnish to the Company a fully completed questionnaire at least two Business Days prior to the Filing Date. The Company may require each selling Holder to furnish to the Company a certified
statement as to the number of shares of Common Stock beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting and dispositive control over the Shares. Following the effective date of such
registration, the Company shall upon the request of any owner of Warrants and/or Warrant Shares forthwith supply such number of prospectuses meeting the requirements of the Securities Act as shall be requested by such owner to permit such Holder to
make a public offering of all Warrant Shares from time to time offered or sold to such Holder, provided that such Holder shall from time to time furnish the Company with such appropriate information (relating to the intentions of such Holder) as the
Company shall request in writing. The Company shall also use its best efforts to qualify the Warrant Shares for sale in such states as such Holder shall reasonably designate. The Company may withdraw the registration at any time.

 6.4 Indemnity. The Company shall indemnify and hold harmless each such Holder and
each underwriter, if any, within the meaning of the Securities Act, who may purchase from or sell for any such Holder any Warrant Shares from and against any and all losses, claims, damages and liabilities caused by any untrue statement or alleged
untrue statement of a material fact contained in the registration statement or any post-effective amendment thereto or any registration statement under the Securities Act or any prospectus included therein required to be filed or furnished by reason
of this Section 6 or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading except insofar as such losses, claims, damages or
liabilities are caused by any such untrue statement or alleged untrue statement or omission or alleged omission based upon information furnished or required to be furnished in writing to the Company by such Holder or underwriter expressly for use
therein, which indemnification shall include each person, if any, who controls any such underwriter within the meaning of the Securities Act; provided, however, that the Company shall not be obliged so to indemnify any such Holder or underwriter or
controlling person unless such Holder or underwriter shall at the same time agree to indemnify the Company, its directors, each officer signing the related registration statement and each person, if any, who controls the Company within the meaning
of the Securities Act, from and against any and all losses, claims, damages and liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in any registration statement or any prospectus required to be filed
or furnished by reason of this Section 6 or caused by any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading insofar as such losses, claims, damages or liabilities
are caused by any untrue statement or alleged untrue statement or omission based upon information furnished in writing to the Company by any such Holder or underwriter expressly for use therein. 

6.5. Registration Expenses. The Holder thereof shall pay all transfer taxes, if any, relating to the sale of its shares, any
registration fees, underwriting discounts or commissions or the equivalent thereof applicable to the sale of its shares and the fees of his own counsel. Other than as described in the preceding sentence, the Company shall pay all expenses incident
to the registration of the Warrant Shares by the Company, including, without limitation, all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, underwriting discounts, fees and expenses (other than any
Holder’s portion of any underwriting discounts or commissions or the equivalent thereof), printing expenses, messenger and delivery expenses, and reasonable fees and expenses of counsel for the Company and the independent certified public
accountants and other persons retained by the Company.

 (ii) Upon the occurrence of any adjustments pursuant to
Section 3 hereof, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment in accordance with the terms hereof and furnish to Holder a certificate
setting forth such adjustment and showing in detail the facts upon which such adjustment is based.

representing at least 51% of the number of shares of Common Stock then subject to outstanding Class B Warrants. Notwithstanding the foregoing, (a) this Warrant may be amended and the observance of any term hereunder may be waived without the
