 W I T N E S S E T H 

WHEREAS, the Company is engaged in a public rights offering (the “Offering”) pursuant to which the Company has distributed,
at no charge, non-transferable subscription rights to purchase units (the “Units”) to each of the Company’s holders of common stock (the “Common Stock”) and the holders
of warrants issued in a private placement transaction that was consummated on June 10, 2020 (the “June 2020 Warrants”) pursuant to an effective registration statement on Form S-1 (File No. 333-238914) (the “Registration Statement”); 
 WHEREAS, the Units consist of
shares of Series F Convertible Preferred Stock (the “Preferred Stock”) and warrants (collectively, the “Warrants”) to purchase shares of Common Stock, and the Company wishes to issue the Warrants in book entry form
entitling the respective holders of the Warrants to purchase an aggregate of up to 37,500,000 shares of Common Stock upon the terms and subject to the conditions hereinafter set forth; 

WHEREAS, the Preferred Stock and Warrants to be issued in connection with the Offering shall be immediately separable and will be issued
separately, but will be purchased together in the Offering; and 
 WHEREAS, the Company wishes the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing so to act, in connection with the issuance, registration, transfer, exchange, exercise and replacement of the Warrants and, in the Warrant Agent’s capacity as the Company’s transfer agent, the
delivery of the Warrant Shares (as defined below). 
 NOW, THEREFORE, in consideration of the premises and the mutual agreements herein set
forth, the parties hereby agree as follows: 
 Section 1. Certain Definitions. For purposes of this Agreement, the following
terms have the meanings indicated:

(b) “Close of Business” on any given date means 5:00 p.m., New York City time, on such

limited liability company, joint venture, trust, unincorporated organization, government or political subdivision thereof or governmental agency or other entity. 

(d) “Warrant Certificate” means a certificate issued to a Holder (as defined below), representing such number of Warrant
Shares as is indicated therein in the form of Exhibit 1 to this Agreement. 
 (e) “Warrant Shares” means the shares of
Common Stock underlying the Warrants and issuable upon exercise of the Warrants. 
 All other capitalized terms used but not otherwise
defined herein shall have the meaning ascribed to such terms in the Warrant. 
 Section 2. Appointment of Warrant Agent. The
Company hereby appoints the Warrant Agent to act as agent for the Company in accordance with the express terms and conditions hereof, and the Warrant Agent hereby accepts such appointment. The Company may from time to time appoint a Co-Warrant Agent as it may, in its sole discretion, deem necessary or desirable upon ten (10) calendar days’ prior written notice to the Warrant Agent. The Warrant Agent shall have no duty to supervise,
and will in no event be liable for the acts or omissions of, any co-Warrant Agent. In the event the Company appoints one or more co-Warrant Agents, the respective duties
of the Warrant Agent and any co-Warrant Agent shall be delineated by the Company as the Company reasonably determines, provided that such duties and determination are consistent with the terms and provisions
of this Agreement and that contemporaneously with such appointment, if any, the Company shall notify the Warrant Agent in writing thereof. 

Section 3. Global Warrants. 

(a) The Warrants shall be initially issuable in book-entry form. Unless otherwise instructed by the Company, all of the Warrants shall
initially be represented by one or more book-entry form Warrants (the “Global Warrants”) deposited with the Warrant Agent and registered in the name of Cede & Co., a nominee of The Depository Trust Company (the
“Depositary”), or as otherwise directed by the Depositary. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the
Depositary or its nominee for each Global Warrant or (ii) institutions that have accounts with the Depositary (such institution, with respect to a Warrant in its account, a “Participant”). 

(b) If the Depositary subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the
Warrant Agent in writing regarding other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide
written instructions to the Depositary to deliver to the Warrant Agent for cancellation each Global Warrant, and the Company shall instruct the Warrant Agent in writing to deliver to each Holder a Warrant Certificate. 

  
 3 













 (c) A Holder has the right to elect at any time or from time to time a Warrant Exchange (as
defined below) pursuant to a Warrant Certificate Request Notice (as defined below). Upon written notice by a Holder to the Warrant Agent for the exchange of some or all of such Holder’s Global Warrants for a Warrant Certificate evidencing the
same number of Warrants, which request shall be in the form attached hereto as Annex A (a “Warrant Certificate Request Notice” and the date of delivery of such Warrant Certificate Request Notice by the Holder, the
“Warrant Certificate Request Notice Date” and the deemed surrender upon delivery by the Holder of a number of Global Warrants for the same number of Warrants evidenced by a Warrant Certificate, a “Warrant
Exchange”), the Warrant Agent shall promptly effect the Warrant Exchange and shall promptly issue and deliver to the Holder a Warrant Certificate for such number of Warrants in the name set forth in the Warrant Certificate Request Notice.
Such Warrant Certificate shall be dated the original issue date of the Warrants and shall be executed by an authorized signatory of the Company. In connection with a Warrant Exchange, the Company agrees to deliver, or to direct the Warrant Agent to
deliver, the Warrant Certificate to the Holder within three (3) Business Days of the Warrant Certificate Request Notice pursuant to the delivery instructions in the Warrant Certificate Request Notice (“Warrant Certificate Delivery
Date”). The Company covenants and agrees that, upon the date of delivery of the Warrant Certificate Request Notice, the Holder shall be deemed to be the holder of the Warrant Certificate and, notwithstanding anything to the contrary set
forth herein, the Warrant Certificate shall be deemed for all purposes to contain all of the terms and conditions of the Warrants evidenced by such Warrant Certificate and the terms of this Agreement (other than Section 3(c), which shall not
apply to the Warrants evidenced by a Warrant Certificate). 
 (d) The Company shall provide an opinion of counsel upon the consummation of
the Offering to set up a reserve of Warrant Shares for the outstanding Warrants. The opinion shall state that all Warrants or Warrant Shares, as applicable, are: “registered under the Securities Act of 1933, as amended (the “1933
Act”), or are exempt from such registration, and all appropriate state securities law filings have been made with respect to the warrants or shares or alternatively, that the securities are “covered securities” under
Section 18 of the 1933 Act; and validly issued, fully paid and non-assessable.” 

Section 4. Form of Warrant. The Warrants, together with the form of election to purchase Common Stock (the “Exercise
Notice”) and the form of assignment to be printed on the reverse thereof, whether a Warrant Certificate or a Global Warrant, shall be substantially in the form of Exhibit 1 hereto. 

Section 5. Countersignature and Registration. The Warrant Certificates shall be executed on behalf of the Company by its Chief
Executive Officer or Principal Financial Officer, either manually or by facsimile signature. The Warrant Certificates shall be countersigned by the Warrant Agent either manually or by facsimile signature and shall not be valid for any purpose unless
so countersigned. In case any officer of the Company who shall have signed a Warrant Certificate shall cease to be such officer of the Company before countersignature by the Warrant Agent and issuance and delivery by the Company, such Warrant
Certificate, nevertheless, may be countersigned by the Warrant Agent, issued and delivered with the same force and effect as though the person who signed such Warrant Certificate had not ceased to be such officer of the Company; and any Warrant
Certificate may be signed on behalf of the Company by any person who, at the actual date of the execution of such Warrant Certificate, shall be a proper officer of the Company to sign such Warrant Certificate, although at the date of the execution
of this Agreement any such person was not such an officer. 

  
 4 













 The Warrant Agent will keep or cause to be kept, at one of its offices, or at the office of
one of its agents, books for registration of original issuance and the registration of transfer of the Warrants issued hereunder (the “Warrant Register”). Such books shall show the names and addresses of the respective holders of
the Warrants (the “Holders” which term shall include transferees, successors and assignees under the terms hereunder and, if the Warrants are held in “street name,” a Participant), the number of Warrant Shares evidenced by
each Global Warrant or on the face of each Warrant Certificate and the date of each of such Warrant Certificate or Global Warrant. Any Person in whose name ownership of a beneficial interest in the Warrants evidenced by a Global Warrant is recorded
in the records maintained by the Depository or its nominee shall be deemed the “beneficial owner” thereof, provided that all such beneficial interests shall be held through a Participant, which shall be the registered holder of such
Warrants. 
 Prior to due presentment for registration of transfer of any Warrant Certificate, the Warrant Agent may deem and treat the
Person in whose name that Warrant shall be registered on the Warrant Register as the absolute owner of such Warrant for purposes of any exercise thereof, and for all other purposes. The Warrant Agent shall not be affected by any notice to the
contrary. Notwithstanding the foregoing, nothing herein shall prevent the Warrant Agent or any agent of the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished by the Depository governing the
exercise of the rights of a holder of a beneficial interest in any Warrant. The rights of beneficial owners in a Warrant evidenced by the Global Warrant shall be exercised by the Holder or a Participant through the Depository’s system, except
to the extent expressly set forth herein. 
 Section 6. Transfer, Split Up, Combination and Exchange of Warrant Certificates;
Mutilated, Destroyed, Lost or Stolen Warrant Certificates. Subject to the provisions of the Warrant and the last sentence of this first paragraph of Section 6 and subject to applicable law, rules or regulations, or any “stop
transfer” instructions the Company may give to the Warrant Agent in writing, at any time after the closing date of the Offering, and at or prior to the Close of Business on the Termination Date, any Warrant Certificate or Warrant Certificates
may be transferred, split up, combined or exchanged for another Warrant Certificate or Warrant Certificates, entitling the Holder to purchase a like number of shares of Common Stock as the Warrant Certificate or Warrant Certificates surrendered then
entitled such Holder to purchase. Any Holder desiring to transfer, split up, combine or exchange any Warrant Certificate shall make such request in writing delivered to the Warrant Agent, and shall surrender the Warrant Certificate or Warrant
Certificates to be transferred, split up, combined or exchanged at the office of the Warrant Agent designated for such purposes. Any requested transfer of Warrants represented by a Warrant Certificate, shall be accompanied by reasonable evidence of
authority of the party making such request that may be required by the Warrant Agent including but not limited to, the signature guarantee of a guarantor institution which is a participant in a signature guarantee program approved by the Securities
Transfer Association. Thereupon the Warrant Agent shall, subject to the last sentence of this first paragraph of Section 6, countersign and deliver to the Person entitled thereto any Warrant Certificate as so requested. The Company may require
payment from the Holder of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Warrants. The Warrant Agent shall not have any duty or obligation to take
any action under any section of this Agreement that requires the payment of taxes and/or charges unless and until it is satisfied that all such payments have been made. 

  
 5 













 Upon receipt by the Warrant Agent of evidence reasonably satisfactory to it of the loss,
theft, destruction or mutilation of a Warrant Certificate, which evidence shall include an affidavit of loss, or in the case of mutilated certificates, the certificate or portion thereof remaining, and, in case of loss, theft or destruction, of
indemnity in customary form and amount satisfactory to the Warrant Agent, and satisfaction of any other reasonable requirements established by established by Section 8-405 of the Uniform Commercial Code
as in effect in the State of Delaware, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto, and upon surrender to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the
Company will make and deliver a new Warrant Certificate of like tenor to the Warrant Agent for delivery to the Holder in lieu of the Warrant Certificate so lost, stolen, destroyed or mutilated. Notwithstanding anything herein to the contrary, in
connection with a Warrant in book entry or electronic form held through the Depositary, no posting of a bond shall be required under this Section 6. 

Section 7. Exercise of Warrants; Exercise Price; Termination Date. 

(a) The Warrants shall be exercisable commencing on the Initial Exercise Date. The Warrants shall cease to be exercisable and shall terminate
and become void, and all rights thereunder and under this Agreement shall cease, at or prior to the Close of Business on the Termination Date. Subject to the foregoing and to Section 7(b) below, the Holder of a Warrant may exercise the Warrant
in whole or in part upon providing the items required by Section 7(c) below to the Warrant Agent at the office of the Warrant Agent designated for such purposes or to the office of one of its agents as may be designated by the Warrant Agent
from time to time. In the case of the Holder of a Warrant Certificate, the Holder shall deliver the executed Exercise Notice and payment of the Exercise Price pursuant to Section 2(a) of the Warrant. Notwithstanding any other provision in this
Agreement, a holder whose interest in a Global Warrant is a beneficial interest in a Global Warrant held in book-entry form through the Depositary (or another established clearing corporation performing similar functions and subject to registration
under the Securities Exchange Act of 1934, as amended), shall effect exercises by delivering to the Depositary (or such other clearing corporation, as applicable) the appropriate instruction form for exercise, complying with the procedures to effect
exercise that are required by the Depositary (or such other clearing corporation, as applicable). The Company acknowledges that the bank accounts maintained by the Warrant Agent in connection with the services provided under this Agreement will be
in Computershare’s name, as agent for the Company, and that the Warrant Agent may receive investment earnings in connection with the investment at Warrant Agent risk and for its benefit of funds (the “Funds”) held in those
accounts from time to time. Until paid pursuant to the terms of this Agreement, Computershare will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating
above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). Computershare shall have no responsibility or
liability for any diminution of the Funds that may result from any deposit made by Computershare in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other third
party. Computershare may from time to time receive interest, dividends or other earnings in connection with such deposits. Computershare shall not be obligated to pay such interest, dividends or earnings to the Company, any holder or any
other party.

 (b) Upon receipt of an Exercise Notice for a cashless exercise pursuant to Section 2(c)
of the Warrant (each, a “Cashless Exercise”), the Warrant Agent will promptly notify the Company and the Company will promptly calculate and transmit to the Warrant Agent the number of Warrant Shares issuable in connection with such
Cashless Exercise and deliver a copy of the Exercise Notice to the Warrant Agent, which shall issue such number of Warrant Shares in connection with such Cashless Exercise. The Warrant Agent shall have no obligation under this Agreement to
calculate, the number of shares of Common Stock to be issued on a Cashless Exercise, which will be determined by the Company (with written notice thereof to the Warrant Agent) using the formula set forth in Section 2(c) of the Warrant. The
Warrant Agent shall have no duty or obligation to investigate or confirm whether the Company’s determination of the number of shares of Common Stock to be issued on such exercise, pursuant to Section 2(c) of the Warrant, is accurate or
correct. 
 (c) Upon the exercise of the Warrant Certificate pursuant to the terms of Section 2 of the Warrant Certificate, accompanied
by such other documentation as the Warrant Agent may reasonably request, the Warrant Agent shall cause the Warrant Shares underlying such Warrant Certificate or Global Warrant to be delivered to or upon the order of the Holder of such Warrant
Certificate or Global Warrant, registered in such name or names as may be designated by such Holder, no later than the Warrant Share Delivery Date (as such term is defined in the Warrant Certificate). If the Company is then a participant in the DWAC
system of the Depositary and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder or (B) the Warrant is being exercised via Cashless Exercise,
then the certificates for Warrant Shares shall be transmitted by the Warrant Agent to the Holder by crediting the account of the Holder’s broker with the Depositary through its DWAC system. For the avoidance of doubt, if the Company becomes
obligated to pay any amounts to any Holders pursuant to Section 2(d)(i) or 2(d)(iv) of the Warrant Certificate, such obligation shall be solely that of the Company and not that of the Warrant Agent. Notwithstanding anything else to the contrary
in this Agreement, except in the case of a Cashless Exercise, if any Holder fails to duly deliver payment to the Warrant Agent of an amount equal to the aggregate Exercise Price of the Warrant Shares to be purchased upon exercise of such
Holder’s Warrant as set forth in Section 7(a) hereof by the Warrant Share Delivery Date, the Warrant Agent will not obligated to deliver such Warrant Shares (via DWAC or otherwise) until following receipt of such payment, and the
applicable Warrant Share Delivery Date shall be deemed extended by one day for each day (or part thereof) until such payment is delivered to the Warrant Agent. For purposes of clarity, the Company and Warrant Agent acknowledge and agree that, with
respect to the terms of the Warrants, the Warrant Certificate or Global Warrant shall set forth the terms of the Warrants and, in the event of any conflict between the Warrant Certificate or the Global Warrant and this Agreement, the Warrant
Certificate or the Global Warrant shall control; provided, however, that all provisions with respect to the rights, duties, obligations, protections, immunities and liability of the Warrant Agent only shall be determined and interpreted solely by
the provisions of this Agreement and, except as related to the rights, duties, obligations, protections, immunities and liability of the Warrant Agent, no provision of this Agreement shall affect or limit the obligations of the Company under the
Warrant in respect of any other Person. 
 (d) The Warrant Agent shall deposit all funds received by it in payment of the Exercise Price for
all Warrants in the account of the Company maintained with the Warrant Agent for such purpose and shall advise the Company via telephone at the end of each day on which funds for the exercise of any Warrant are received of the amount so deposited to
its account. The Warrant Agent shall promptly confirm such telephonic advice to the Company in writing. 

  
 7 













 (e) In case the Holder of any Warrant Certificate exercises fewer than all Warrants
evidenced thereby and surrenders such Warrant Certificate in connection with such partial exercise, a new Warrant Certificate evidencing the number of Warrant Shares equivalent to the number of Warrant Shares remaining unexercised may be issued by
the Warrant Agent to the Holder of such Warrant Certificate or to his duly authorized assigns in accordance with Section 2(d)(ii) of the Warrant, subject to the provisions of Section 6 hereof. 

(f) In the event of a cash exercise, the Company hereby instructs the Warrant Agent to record cost basis for newly issued shares in a manner to
be subsequently communicated by the Company in writing to the Warrant Agent. In the event of a Cashless Exercise, the Company shall provide cost basis for shares issued pursuant to a Cashless Exercise at the time the Company confirms the number of
Warrant Shares issuable in connection with the Cashless Exercise to the Warrant Agent pursuant to Section 7(a) hereof 
 (g)
Notwithstanding anything to the contrary contained herein, upon giving irrevocable instructions to its Participant to exercise Warrants, solely for purposes of Regulation SHO, the holder whose interest in the Warrant is a beneficial interest shall
be deemed to have exercised such Warrant, regardless of when the applicable Warrant Shares are delivered to such holder. . 

Section 8. Cancellation and Destruction of Warrant Certificates. All Warrant Certificates surrendered for the purpose of exercise,
transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the Warrant Agent for cancellation or in canceled form, or, if surrendered to the Warrant Agent, shall be canceled by it, and
no Warrant Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement or the Warrants. The Company shall deliver to the Warrant Agent for cancellation and retirement, and the Warrant Agent
shall so cancel and retire, any other Warrant Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Warrant Agent shall deliver all canceled Warrant Certificates to the Company, or shall, at the written
request of the Company, destroy such canceled Warrant Certificates, and in such case shall deliver a certificate of destruction thereof to the Company, subject to any applicable law, rule or regulation requiring the Warrant Agent to retain such
canceled certificates. 
 Section 9. Certain Representations; Reservation and Availability of Shares of Common Stock or Cash. 

(a) This Agreement has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery
hereof by the Warrant Agent, constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms, and the Warrants have been duly authorized, executed and issued by the Company and, assuming
due registration thereof by the Warrant Agent pursuant hereto and payment therefor by the Holders as provided in the Registration Statement, constitute valid and legally binding obligations of the Company enforceable against the Company in
accordance with their terms and entitled to the benefits thereof; in each case except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights
generally or by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law). 

  
 8 













 (b) As of the date hereof and prior to the Offering, the authorized capital stock of the
Company consists of (i) 180,000,000 shares of Common Stock, of which 50,342,130 shares of Common Stock are issued and outstanding, and (ii) 1,000,000 shares of preferred stock, par value $0.001 per share, and none of which is issued and outstanding.
As of the date hereof, 37,500,000 shares of Common Stock are reserved for issuance upon exercise of the Warrants. Except as disclosed in the Registration Statement, there are no other outstanding obligations, warrants, options or other rights
to subscribe for or purchase from the Company any class of capital stock of the Company. 
 (c) The Company covenants and agrees that it will
cause to be reserved and kept available out of its authorized and unissued shares of Common Stock or its authorized and issued shares of Common Stock held in its treasury, free from preemptive rights, the number of shares of Common Stock that will
be sufficient to permit the exercise in full of all outstanding Warrants. 
 (d) [Intentionally Omitted]. 

(e) The Company further covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges
which may be payable in respect of the original issuance or delivery of the Warrant Certificates or certificates evidencing Common Stock upon exercise of the Warrants. The Company shall not, however, be required to pay any tax or governmental charge
which may be payable in respect of any transfer involved in the transfer or delivery of Warrant Certificates or the issuance or delivery of certificates for Common Stock in a name other than that of the Holder of the Warrant Certificate evidencing
Warrants surrendered for exercise or to issue or deliver or cause to be issued or delivered, any certificate for shares of Common Stock upon the exercise of any Warrants until any such tax or governmental charge shall have been paid (any such tax or
governmental charge being payable by the Holder of such Warrant Certificate at the time of surrender) or until it has been established to the Company’s or the Warrant Agent’s reasonable satisfaction that no such tax or governmental charge
is due. 
 Section 10. Common Stock Record Date. Each Holder shall be deemed to have become the holder of record for the Warrant
Shares pursuant to Section 2(d)(i) of the Warrants. 
 Section 11. Adjustment of Exercise Price, Number of Shares of Common
Stock or Number of the Company Warrants. The Exercise Price, the number of shares covered by each Warrant and the number of Warrants outstanding are subject to adjustment from time to time as provided in Section 3 of the Warrant
(“Adjustment Events”). In the event that at any time, as a result of an adjustment made pursuant to Section 3 of the Warrant, the Holder of any Warrant thereafter exercised shall become entitled to receive any shares of capital
stock of the Company other than shares of Common Stock, thereafter the number of such other shares so receivable upon exercise of any Warrant shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the shares contained in Section 3 of the Warrant, and the provisions of Sections 7, 9 and 13 of this Agreement with respect to the 

  
 9 













 
shares of Common Stock shall apply on like terms to any such other shares. All Warrants originally issued by the Company subsequent to any adjustment made to the Exercise Price pursuant to the
Warrant shall evidence the right to purchase, at the adjusted Exercise Price, the number of shares of Common Stock purchasable from time to time hereunder upon exercise of the Warrants, all subject to further adjustment as provided herein. The
Company hereby agrees that it will provide the Warrant Agent with reasonable notice of Adjustment Events. The Warrant Agent shall have no obligation under any Section of this Agreement to determine whether an Adjustment Event has occurred or to
calculate any of the adjustments set forth herein. 
 Section 12. Certification of Adjusted Exercise Price or Number of Shares of
Common Stock. Whenever the Exercise Price or the number of shares of Common Stock issuable upon the exercise of each Warrant is adjusted as provided in Section 11 or 13, the Company shall (a) promptly prepare a certificate setting
forth the Exercise Price of each Warrant as so adjusted, and a brief, detailed statement of the facts accounting for such adjustment, and (b) promptly file with the Warrant Agent and with each transfer agent for the Common Stock a copy of such
certificate. The Company may instruct the Warrant Agent to send a notice including such brief, detailed statement of the facts accounting for the adjustment and a brief summary of any new or amended exercise terms to each Holder of a Warrant. If the
Company requests the Warrant Agent to send such notices, it shall provide the Warrant Agent with a draft notice to be used for this purpose. The Warrant Agent shall be fully protected in relying on any such certificate and on any adjustment or
statement therein contained and shall have no duty or liability with respect to, and shall not be deemed to have knowledge of any such adjustment or any such event unless and until it shall have received such certificate. 

Section 13. Fractional Shares of Common Stock. 

(a) The Company shall not issue Warrants representing fractional shares or distribute a Global Warrant or Warrant Certificate that evidences
fractional shares. Whenever any Warrant representing fractional shares would otherwise be required to be issued or distributed, the actual issuance or distribution shall reflect a rounding of such fraction in accordance with Section 2(d)(v) of
the Warrant. 
 (b) The Company shall not issue fractions of shares of Common Stock upon exercise of Warrants or distribute stock
certificates that evidence fractional shares of Common Stock. Whenever any fraction of a share of Common Stock would otherwise be required to be issued or distributed, the actual issuance or distribution in respect thereof shall be made in
accordance with Section 2(d)(v) of the Warrant. 
 Section 14. Conditions of the Warrant Agent’s Obligations. The
Warrant Agent accepts its obligations herein set forth upon the express terms and conditions hereof, including the following to all of which the Company agrees and to all of which the rights hereunder of the Holders from time to time of the Warrant
shall be subject: 
 (a) Compensation and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation in
accordance with a fee schedule to be mutually agreed upon for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket
expenses (including reasonable counsel fees) incurred in the preparation, delivery, 

  
 10 













 
negotiation, amendment, administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Company covenants and agrees to indemnify and to hold the
Warrant Agent harmless against, any and all loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense (including, without limitation, the reasonable fees and expenses of legal counsel) that may be paid, incurred or
suffered by it, or which it may become subject, without gross negligence, bad faith or willful misconduct on the part of the Warrant Agent (which gross negligence, bad faith, or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction), for any action taken, suffered, or omitted to be taken by the Warrant Agent in connection with the execution, acceptance, administration, exercise and
performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights hereunder. Notwithstanding anything contained herein to
the contrary, the Warrant Agent’s aggregate liability to the Company during any term of this Agreement with respect to, arising from, or arising in connection with this Agreement, or from all services provided or omitted to be provided under
this Agreement, whether in contract, or in tort, or otherwise, is limited to, and shall not exceed, the amounts paid hereunder by the Company to Warrant Agent as fees and charges, but not including reimbursable expenses, during the twelve
(12) months immediately preceding the event for which recovery from Warrant Agent is being sought. The obligations of the Company set forth in this paragraph and the rights and immunities of the Warrant Agent under this Section 14 shall
survive the termination of this Agreement and the resignation or removal of the Warrant Agent. 
 (b) Agent for the Company. In acting under
this Agreement and in connection with the Warrant Certificates, the Warrant Agent is acting solely as agent of the Company and does not assume any obligations or relationship of agency or trust for or with any of the Holders of Warrant Certificates
or beneficial owners of Warrants. 
 (c) Counsel. The Warrant Agent may consult with counsel satisfactory to it, which may include counsel
for the Company, and the advice or opinion of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in the absence of bad faith and in accordance with the advice or
opinion of such counsel. 
 (d) Documents. The Warrant Agent shall be protected and shall incur no liability for or in respect of any action
taken or omitted by it in reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other paper or document reasonably believed by it to be genuine and to have been presented or signed by the proper
parties. 
 (e) Certain Transactions. The Warrant Agent, and its officers, directors and employees, may become the owner of, or acquire any
interest in, the Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to the extent permitted by applicable law, it or they may engage or be interested in any financial or other transaction with
the Company and may act on, or as depositary, trustee or agent for, any committee or body of Holders of Warrants or other obligations of the Company as freely as if it were not the Warrant Agent hereunder. Nothing in this Agreement shall be deemed
to prevent the Warrant Agent from acting as trustee under any indenture to which the Company is a party. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity. 

  
 11 













 (f) No Liability for Interest. Unless otherwise agreed with the Company, the Warrant Agent
shall have no liability for interest on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates. 

(g) No Liability for Invalidity. The Warrant Agent shall have no liability with respect to any invalidity of this Agreement or any of the
Warrant Certificates (except as to the Warrant Agent’s countersignature thereon). 
 (h) No Responsibility for Representations. The
Warrant Agent shall not be responsible for any of the recitals, statement of facts or representations herein or in the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon) or be required to verify the same, all of
which are made solely by the Company. 
 (i) (i) No Implied Obligations. The Warrant Agent shall be obligated to perform only such duties as
are herein and in the Warrants specifically set forth and no implied duties or obligations shall be read into this Agreement or the Warrants against the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action hereunder
which may tend to involve it in any expense or liability, the payment of which within a reasonable time or adequate indemnification is not, in its reasonable opinion, assured to it. The Warrant Agent shall not be accountable or under any duty or
responsibility for the use by the Company of any of the Warrants authenticated by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or for the application by the Company of the proceeds of the Warrants. The Warrant
Agent shall have no duty or responsibility in case of any default by the Company in the performance of its covenants or agreements contained herein or in the Warrants or in the case of the receipt of any written demand from a Holder of a Warrant
with respect to such default, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law. 

Section 15. Purchase or Consolidation or Change of Name of Warrant Agent. Any Person into which the Warrant Agent or any successor
Warrant Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Warrant Agent or any successor Warrant Agent shall be party, or any Person succeeding to the corporate trust,
stock transfer or shareholder services business of the Warrant Agent or any successor Warrant Agent, shall be the successor to the Warrant Agent under this Agreement without the execution or filing of any paper or any further act on the part of any
of the parties hereto, provided that such corporation would be eligible for appointment as a successor Warrant Agent under the provisions of Section 17. In case at the time such successor Warrant Agent shall succeed to the agency created by
this Agreement any of the Warrants shall have been countersigned but not delivered, any such successor Warrant Agent may adopt the countersignature of the predecessor Warrant Agent and deliver such Warrants so countersigned; and in case at that time
any of the Warrants shall not have been countersigned, any successor Warrant Agent may countersign such Warrants either in the name of the predecessor Warrant Agent or in the name of the successor Warrant Agent; and in all such cases such Warrants
shall have the full force provided in the Warrants and in this Agreement. 

  
 12 













 In case at any time the name of the Warrant Agent shall be changed and at such time any of
the Warrants shall have been countersigned but not delivered, the Warrant Agent may adopt the countersignature under its prior name and deliver Warrants so countersigned; and in case at that time any of the Warrants shall not have been
countersigned, the Warrant Agent may countersign such Warrants either in its prior name or in its changed name; and in all such cases such Warrants shall have the full force provided in the Warrants and in this Agreement. 

Section 16. Duties of Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the
following express terms and conditions, by all of which the Company, by its acceptance hereof, shall be bound: 
 (a) Whenever in the
performance of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless
other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chief Executive Officer or Principal Financial Officer of the Company; and such certificate
shall be full authentication to the Warrant Agent for any action taken or suffered by it under the provisions of this Agreement in reliance upon such certificate. The Warrant Agent shall not be liable and shall be indemnified by the Company for any
action taken or omitted by the Warrant Agent in reliance upon any such Company certificate. The Warrant Agent shall not be held to have notice of any change of authority of any person until receipt of written notice thereof from the Company. 

(b) Subject to Section 29, the Warrant Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct
(which gross negligence, bad faith and willful misconduct must be determined by a final non-appealable judgment of a court of competent jurisdiction). 

(c) The Warrant Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Warrant Agent) or in respect of the validity or execution of any Warrant (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained
in this Agreement or in any Warrant; nor shall it be responsible for the adjustment of the Exercise Price or the making of any change in the number of shares of Common Stock required under the provisions of Section 11 or 13 or responsible for
the manner, method or amount of any such change or the ascertaining of the existence of facts that would require any such adjustment or change (but not limiting the Warrant Agent’s duties herein set forth upon the exercise of Warrants evidenced
by Warrant Certificates after actual notice of any adjustment of the Exercise Price); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be
issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock will, when issued, be duly authorized, validly issued, fully paid and nonassessable. 

  
 13 













 (d) From time to time, the Chief Executive Officer or Principal Financial Officer of the
Company may provide Warrant Agent with instructions concerning the services performed by the Warrant Agent hereunder. In addition, at any time Warrant Agent may apply to these officers for instruction, and may consult with legal counsel for Warrant
Agent or Company with respect to any matter arising in connection with the services to be performed by the Warrant Agent under this Agreement. Warrant Agent and its agents and subcontractors shall not be liable and shall be indemnified by Company
for any action taken or omitted by Warrant Agent in reliance upon any Company instructions or upon the advice or opinion of such counsel. Warrant Agent shall not be held to have notice of any change of authority of any person, until receipt of
written notice thereof from Company. 
 (e) The Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or
perform any duty hereunder either itself or by or through its attorney or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorney or agents or for any loss to the Company
resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof. 

(f) The Warrant Agent shall forward funds received for Warrant exercises by the fifth Business Day of the following month after such funds are
received by the Warrant Agent by wire transfer to an account designated by the Company. 
 (g) This Section 16 shall survive the
termination of this Agreement and the resignation or removal of the Warrant Agent. 
 Section 17. Change of Warrant Agent. The
Warrant Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice in writing sent to the Company and, and in the event that the Warrant Agent or one of its affiliates is not also the transfer agent for the
Common Stock, to each transfer agent of the Common Stock known to the Warrant Agent, and to the Holders of the Warrant Certificates. In the event the transfer agency relationship in effect between the Company and the Warrant Agent terminates, the
Warrant Agent will be deemed to have resigned automatically and be discharged from its duties under this Agreement as of the effective date of such termination, and the Company shall be responsible for sending any required notice prescribed in this
Section 17. The Company may remove the Warrant Agent or any successor Warrant Agent upon 30 days’ notice in writing, sent to the Warrant Agent or successor Warrant Agent, as the case may be, and to each transfer agent of the Common Stock,
and to the Holders of the Warrant Certificates. If the Warrant Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Warrant Agent. If the Company shall fail to make such
appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Warrant Agent or by the Holder of a Warrant Certificate (who shall, with such
notice, submit his Warrant Certificate for inspection by the Company), then the Holder of any Warrant Certificate may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent. Any successor Warrant Agent, whether
appointed by the Company or by such a court, shall be an entity organized and doing business under the laws of the United States or of a state thereof, in good standing, which is authorized under such laws to exercise stock transfer powers and is
subject to supervision or examination by federal or state authority and which has at 

  
 14 













 
the time of its appointment as Warrant Agent (along with its affiliates) a combined capital and surplus of at least $50,000,000. After appointment, the successor Warrant Agent shall be vested
with the same powers, rights, duties and responsibilities as if it had been originally named as Warrant Agent without further act or deed; but the predecessor Warrant Agent shall deliver and transfer to the successor Warrant Agent any property at
the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose; provided, that, such predecessor Warrant Agent shall not be required to make any additional expenditure or assume any
additional liability in connection with the foregoing. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Warrant Agent and each transfer agent of the Common Stock, and
send a notice thereof in writing to the Holders of the Warrant Certificates. However, failure to give any notice provided for in this Section 17, or any defect therein, shall not affect the legality or validity of the resignation or removal of
the Warrant Agent or the appointment of the successor Warrant Agent, as the case may be. 
 Section 18. Issuance of New
Warrants. Notwithstanding any of the provisions of this Agreement or of the Warrants to the contrary, the Company may, at its option, issue a new Global Warrant or Warrant Certificates, if any, evidencing Warrants in such form as may be approved
by its Board of Directors to reflect any adjustment or change in the Exercise Price per share and the number or kind or class of shares of stock or other securities or property purchasable under the Global Warrant or Warrant Certificate, if any,
made in accordance with the provisions of this Agreement.

Agreement to be given or made (i) by the Warrant Agent or by the Holder of any Warrants to or on the Company, (ii) subject to the provisions of Section 17, by the Company or by the Holder of any Warrants to or on the Warrant Agent or

the Holder of each outstanding warrant certificate affected thereby. As a condition precedent to the Warrant Agent’s execution of any amendment, the Company shall deliver to the Warrant Agent a certificate from a duly authorized officer of the
Company that states that the proposed amendment complies with the terms of this Section 20. Notwithstanding anything in this Agreement to the contrary, the Warrant Agent shall not be required to execute any supplement or amendment to this

Section 24. Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all
purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. A signature to this Agreement transmitted electronically shall have the same authority, effect, and enforceability as an
original signature.

the Securities and Exchange Commission.

Warrant Agent shall not be liable for any delays or failures in performance resulting from acts beyond its reasonable control including, without limitation, acts of God, terrorist acts, epidemics, pandemics, shortage of supply, breakdowns or
malfunctions, interruptions or malfunction of computer facilities, or loss of data due to power failures or mechanical difficulties with information storage or retrieval systems, labor difficulties, war, or civil unrest, it being understood that the
Warrant Agent shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances; provided, however, that this provision shall not affect or
limit in any way the obligations of the Company under the Global Warrants or the Warrant Certificates.

without limitation, pursuant to subpoenas from state or federal government authorities (e.g., in divorce and criminal actions). However, each party may disclose relevant aspects of the other party’s confidential information to its officers,

invalidated; provided, however, that if such excluded provision shall affect the rights, immunities, liabilities, duties or obligations of the Warrant Agent, the Warrant Agent shall be entitled to resign immediately upon written notice to the
Company.
