WARRANTS 

Section 3.1 Issuance of Warrants. On the terms and subject to the conditions of this Agreement, on each closing date of the
Offering (each, a “Closing Date”) or a date that is as soon as reasonably practicable after such Closing Date, but in any event no later than five (5) days after such Closing Date (such date, the “Issue Date”),
the Company will issue Warrants to purchase ten (10) shares of Common Stock for every one (1) share of Series C Preferred Stock purchased by a Purchaser. On such date, the Company will deliver, or cause to be delivered to the Depositary,
one or more Global Warrant Certificates evidencing a portion of the Warrants. The remainder of the Warrants shall be issued by book-entry registration on the books of the Warrant Agent (“Book-Entry Warrants”) and shall be evidenced
by statements issued by the Warrant Agent from time to time to the Registered Holders of Book-Entry Warrants reflecting such book-entry position (the “Warrant Statements”). 

Section 3.2 Form of Warrant. 
 (a) Subject to Section 6.1 of this Agreement, the Warrants shall be issued (i) via book-entry registration on the books and records of the Warrant Agent and evidenced by the Warrant Statements,
in substantially the form set forth in Exhibit A-1 attached hereto, and/or (ii) in the form of one or more global certificates (the “Global Warrant Certificates”), with the forms of election to exercise and of assignment
printed on the reverse thereof, in substantially the form set forth in Exhibit A-2 attached hereto. The Warrant Statements and Global Warrant Certificates may bear such appropriate insertions, omissions, substitutions and other variations as
are required or permitted by this Agreement, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with any law or with any rules made pursuant thereto or
with any rules of any securities exchange or as may, consistently herewith, or, be determined by (i) in the case of Global Warrant Certificates, the Appropriate Officers executing such Global Warrant Certificates, as evidenced by their
execution of the Global Warrant Certificates, or (ii) in the case of a Warrant Statement, any Appropriate Officer, and all of which shall be reasonably acceptable to the Warrant Agent. 

(b) The Global Warrant Certificates shall be deposited on or after the Issue Date with the Warrant Agent and registered in the name of
Cede & Co., as the nominee of The Depository Trust Company (the “Depositary”). Each Global Warrant Certificate shall represent such number of the outstanding Warrants as specified therein, and each shall provide that it shall
represent the aggregate amount of outstanding Warrants from time to time endorsed thereon and that the aggregate amount of outstanding Warrants represented thereby may from time to time be reduced or increased, as appropriate, in accordance with the
terms of this Agreement.

 Section 3.3 Execution of Global Warrant Certificates. 

(a) The Global Warrant Certificates shall be signed on behalf of the Company by its Chairman of the Board of Directors, its Chief
Executive Officer, its President, any Senior Vice President or its Treasurer (each, an “Appropriate Officer”). Each such signature upon the Global Warrant Certificates may be in the form of a facsimile signature of any such
Appropriate Officer and may be imprinted or otherwise reproduced on the Global Warrant Certificates and for that purpose the Company may adopt and use the facsimile signature of any Appropriate Officer. 

(b) If any Appropriate Officer who shall have signed any of the Global Warrant Certificates shall cease to be such Appropriate Officer
before the Global Warrant Certificates so signed shall have been countersigned by the Warrant Agent or disposed of by the Company, such Global Warrant Certificates nevertheless may be countersigned and delivered or disposed of as though such
Appropriate Officer had not ceased to be such Appropriate Officer of the Company; and any Global Warrant Certificate may be signed on behalf of the Company by any person who, at the actual date of the execution of such Global Warrant Certificate,
shall be a proper Appropriate Officer of the Company to sign such Global Warrant Certificate, although at the date of the execution of this Agreement any such person was not such Appropriate Officer. 

Section 3.4 Registration and Countersignature. 
 (a) Upon written order of the Company, the Warrant Agent shall (i) register in the Warrant Register the Book-Entry Warrants and (ii) upon receipt of the Global Warrant Certificates duly executed
on behalf of the Company, countersign one or more Global Warrant Certificates evidencing Warrants. Such written order of the Company shall specifically state the number of Warrants that are to be issued as Book-Entry Warrants and the number of
Warrants that are to be issued as a Global Warrant Certificate. A Global Warrant Certificate shall be, and shall remain, subject to the provisions of this Agreement until such time as all of the Warrants evidenced thereby shall have been duly
exercised or shall have expired or been canceled in accordance with the terms hereof. 
 (b) No Global Warrant Certificate shall
be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Global Warrant Certificate has been countersigned by the manual signature of the Warrant Agent. Such signature by the Warrant Agent upon any Global Warrant
Certificate executed by the Company shall be conclusive evidence that such Global Warrant Certificate so countersigned has been duly issued hereunder. 
 (c) The Warrant Agent shall keep, at an office designated for such purpose, books (the “Warrant Register”) in which, subject to such reasonable regulations as it may prescribe, it shall
register the Book-Entry Warrants as well as any Global Warrant Certificates and exchanges and transfers of outstanding Warrants in accordance with the procedures set forth in Section 6.1 of this Agreement, all in form satisfactory to the
Company and the Warrant Agent. No service charge shall be made for any exchange or registration of transfer of the Warrants, but the Company may require payment of a sum sufficient to cover any stamp or other tax or other governmental charge that
may be imposed on the Registered Holder in connection with any such exchange or registration of transfer. The Warrant Agent shall have no obligation to effect an exchange or register a transfer unless and until any payments required by the
immediately preceding sentence have been made. 

  
 5 

 (d) Prior to due presentment for registration of transfer or exchange of any Warrant in
accordance with the procedures set forth in this Agreement, the Company and the Warrant Agent may deem and treat the person in whose name any Warrant is registered upon the Warrant Register (the “Registered Holder” of such Warrant)
as the absolute owner of such Warrant (notwithstanding any notation of ownership or other writing on a Global Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, any distribution
to the holder thereof and for all other purposes, and neither the Warrant Agent nor the Company shall be affected by notice to the contrary. 
 ARTICLE IV 
 TERMS AND EXERCISE OF WARRANTS 

Section 4.1 Exercise Price. On the Issue Date, each Warrant shall entitle (i) in the case of the Book-Entry Warrants, the
Registered Holder thereof and (ii) in the case of Warrants held through the book-entry facilities of the Depositary or by or through persons that are direct participants in the Depositary, the Beneficial Holder thereof ((i) and
(ii) collectively, the “Holder”), subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of Warrant Shares, at the price of $2.00 per whole share (as the same may be hereafter
adjusted pursuant to Article V, the “Exercise Price”) specified in such Warrant. 
 Section 4.2
Duration of Warrants. Warrants may be exercised by the Holder thereof at any time and from time to time during the period commencing on the Issue Date and terminating at 5:00 p.m., New York City time, on the Expiration Date. Any Warrant not
exercised prior to 5:00 p.m., New York City time, on the Expiration Date, shall become permanently and irrevocably null and void at 5:00 p.m., New York City time, on the Expiration Date, and all rights thereunder and all rights in respect thereof
under this Agreement shall cease at such time. 
 Section 4.3 Method of Exercise. 

(a) Subject to the provisions of the Warrants and this Agreement, the Holder of a Warrant may exercise such Holder’s right to
purchase the Warrant Shares, in whole or in part, by: (x) in the case of persons who hold Book-Entry Warrants, providing an exercise form for the election to exercise such Warrant (“Exercise Form”) substantially in the form of
Exhibit B-1 hereto, properly completed and executed by the Registered Holder thereof, together with payment of the Exercise Amount in accordance with Section 4.5(a), to the Warrant Agent, and (y) in the case of Warrants held
through the book-entry facilities of the Depositary or by or through persons that are direct participants in the Depositary, providing an Exercise Form (as provided by such Holder’s broker) to its broker, properly completed and executed by the
Beneficial Holder thereof, together with payment of the Exercise Amount in accordance with Section 4.5(a). 
 (b)
Any exercise of a Warrant pursuant to the terms of this Agreement shall be irrevocable and shall constitute a binding agreement between the Holder and the Company, enforceable in accordance with its terms. 

(c) The Warrant Agent shall: 
 (i) examine all Exercise Forms and all other documents delivered to it by or on behalf of Holders as contemplated hereunder to ascertain whether or not, on their face, such Exercise Forms and any such
other documents have been executed and completed in accordance with their terms and the terms hereof; 

  
 6 

 (ii) where an Exercise Form or other document appears on its face to have been improperly
completed or executed or some other irregularity in connection with the exercise of the Warrants exists, endeavor to inform the appropriate parties (including the person submitting such instrument) of the need for fulfillment of all requirements,
specifying those requirements which appear to be unfulfilled; 
 (iii) inform the Company of and cooperate with and assist the
Company in resolving any reconciliation problems between Exercise Forms received and the delivery of Warrants to the Warrant Agent’s account; 
 (iv) advise the Company no-later than three (3) Business Days after receipt of an Exercise Form, of (A) the receipt of such Exercise Form and the number of Warrants exercised in accordance with
the terms and conditions of this Agreement, (B) the instructions with respect to delivery of the Warrant Shares deliverable upon such exercise, subject to timely receipt from the Depositary of the necessary information, and (C) such other
information as the Company shall reasonably require; and 
 (v) subject to Warrant Shares being made available to the Warrant
Agent by or on behalf of the Company for delivery to the Depositary, liaise with the Depositary and endeavor to effect such delivery to the relevant accounts at the Depositary in accordance with its customary requirements. 

(d) The Company reserves the right to reasonably reject any and all Exercise Forms not in proper form or for which any corresponding
agreement by the Company to exchange would, in the opinion of the Company, be unlawful. Such determination by the Company shall be final and binding on the Holders of the Warrants, absent manifest error. Moreover, the Company reserves the absolute
right to waive any of the conditions to the exercise of Warrants or defects in Exercise Forms with regard to any particular exercise of Warrants. Neither the Company nor the Warrant Agent shall be under any duty to give notice to the Holders of the
Warrants of any irregularities in any exercise of Warrants, nor shall it incur any liability for the failure to give such notice. 
 Section 4.4 Issuance of Warrant Shares. 
 (a) Upon exercise of any Warrants
pursuant to Section 4.3 and clearance of the funds in payment of the Exercise Price, the Company shall promptly at its expense, and in no event later than five (5) Business Days thereafter, cause to be issued to the Holder of such
Warrants the total number of whole Warrant Shares for which such Warrants are being exercised (as the same may be hereafter adjusted pursuant to Article V) in such denominations as are requested by the Holder as set forth below: 

(i) in the case of a Beneficial Holder who holds the Warrants being exercised through the Depositary’s book-entry transfer
facilities, by same-day or next-day credit to the Depositary for the account of such Beneficial Holder or for the account of a participant in the Depositary the number of Warrant Shares to which such person is entitled, in each case registered in
such name and delivered to such account as directed in the Exercise Form by such 

  
 7 

 
Beneficial Holder or by the direct participant in the Depositary through which such Beneficial Holder is acting, or 
 (ii) in the case of a Registered Holder who holds the Warrants being exercised in the form of Book-Entry Warrants, a book-entry interest in the Warrant Shares registered on the books of the Company’s
transfer agent. 
 (b) If less than all of the Warrants evidenced by a Global Warrant Certificate surrendered upon the exercise
of Warrants are exercised at any time prior to the Expiration Date, a new Global Warrant Certificate or Global Warrant Certificates shall be issued for the remaining number of Warrants evidenced by the Global Warrant Certificate so surrendered, and
the Warrant Agent is hereby authorized to countersign the required new Global Warrant Certificate or Certificates pursuant to the provisions of Section 3.4 and this Section 4.4. 

Section 4.5 Exercise of Warrant. 
 (a) Right to Exercise for Cash. Warrants may be exercised by the Holders thereof by delivery of payment to the Warrant Agent, for the account of the Company, by certified or bank cashier’s
check payable to the order of the Company (or as otherwise agreed to by the Company), in lawful money of the United States of America, of the full Exercise Price for the number of Warrant Shares specified in the Exercise Form (which shall be equal
to the Exercise Price multiplied by the number of Warrant Shares in respect of which any Warrants are being exercised) and any and all applicable taxes and governmental charges due in connection with the exercise of Warrants and the exchange of
Warrants for Warrant Shares (the “Exercise Amount”). 
 (b) Forced Exercise. 

(i) If the price per share of Common Stock is equal to or greater than the volume-weighted average closing price of $3.50 for any ten
(10) consecutive trading-day period (the end of any such period, the “Exercise Trigger Date”) at any time after the Issue Date, the Company, at its option, may elect to force Holders to exercise the Warrants then outstanding
into Warrant Shares, in whole or in part on a pro-rata basis by delivering a notice to each Holder no later than fifteen (15) days following such Exercise Trigger Date as provided in Section 4.5(b)(ii) below (the “Forced
Exercise Notice”). Forced Exercise Notices shall be given no later than fifteen (15) days following the applicable Exercise Trigger Date by mailing, by registered or certified mail, return receipt requested, a copy of such notice to
the Warrant Agent and to all of the holders of record of Warrants at their respective addresses appearing on the Warrant Register or books or transfer records of the Company or such other address designated in writing by the holder of record to the
Warrant Agent. The date of delivery of the Forced Exercise Notice shall be the “Delivery Date.” 
 (ii) The
Holders shall have twenty (20) days following the Delivery Date to exercise the Warrants that have been called for forced exercise pursuant to Section 4.5(b)(i), in the manner provided in Section 4.5(a). Any Warrants
that have been called for forced exercise pursuant to Section 4.5(b)(i), together with payment of the Exercise Price for all such Warrants, that have not been delivered to the Warrant Agent for exercise after twenty (20) days
following the Delivery Date shall be cancelled and all rights of the Holders with respect to such Warrants shall terminate. 

  
 8 

 (iii) Notwithstanding anything to the contrary in this Section 4.5(b), the
Company may not provide a Forced Exercise Notice pursuant to this Section 4.5 at any time at which the Warrants are not currently exercisable as a result of the application of either Section 4.5(c) or Section 4.6.
If, during the period between the Forced Exercise Notice and the Delivery Date, the Warrants become not currently exercisable as a result of the application of either Section 4.5(c) or Section 4.6, the Delivery Date shall be
extended and deemed to be the tenth business day after such restriction on exercise lapses. 
 (c) The Company shall not effect
any exercise of a Warrant, and a Holder shall not have the right to exercise any portion of a Warrant, pursuant to Section 4.5 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the
applicable Exercise Form, such Holder (together with such Holder’s affiliates, and any other persons acting as a group together with such Holder or any of such Holder’s affiliates) would beneficially own in excess of the Beneficial
Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its affiliates shall include the number of shares of Common Stock or Common Stock
Equivalents issuable upon exercise of the Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock or Common Stock Equivalents which would be issuable upon (i) exercise of the
remaining, nonexercised portion of the Warrant beneficially owned by the Holder or any of its affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without
limitation, any other Equity Securities) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or any of its affiliates. Except as set forth in the preceding sentence,
for purposes of this Section 4.5(c), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by such Holder that the
Company is not representing to such Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and such Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that
the limitation contained in this Section 4.5(c) applies, the determination of whether the Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates) and of which portion of the Warrant is
exercisable shall be in the sole discretion of such Holder, and the submission of an Exercise Form shall be deemed to be such Holder’s determination of whether the Warrant is exercisable (in relation to other securities owned by such Holder
together with any affiliates) and of which portion of the Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company and the Warrant Agent shall have no obligation to verify or confirm the accuracy of such
determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this
Section 4.5(c), in determining the number of outstanding shares of Common Stock, such Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report
filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Warrant Agent setting forth the number of shares of Common Stock
outstanding. Upon the written or oral request of a Holder, the Warrant Agent shall, within two (2) Business Days confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the
number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrant, by such Holder or its affiliates since the date as of which such number of
outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock 

  
 9 

 
outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. Such Holder, upon not less than forty-five (45) days’ prior
notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 4.5(c), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common
Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of the Warrant held by such Holder and the provisions of this Section 4.5(c) shall continue to apply. Any such increase or decrease
will not be effective until the 45th day after such notice
is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 4.5(c) to correct this paragraph (or any portion hereof)
which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this
paragraph shall apply to a successor Holder of the Warrant. 
 Section 4.6 Reservation of Shares. The Company hereby
agrees that at all times there shall be reserved for issuance and delivery upon exercise of Warrants such number of Warrant Shares as may be from time to time issuable upon exercise in full of the Warrants. All Warrant Shares shall be duly
authorized, and when issued upon such exercise, shall be validly issued, fully paid and non-assessable, free and clear of all liens, security interests, charges and other encumbrances or restrictions on sale and free and clear of all preemptive
rights, and the Company shall take all such action as may be necessary or appropriate in order that the Company may validly and legally issue all Warrant Shares in compliance with this sentence. If at any time prior to the Expiration Date the number
and kind of authorized but unissued shares of the Company’s capital stock shall not be sufficient to permit exercise in full of the Warrants, the Company will promptly take such corporate action as may, in the opinion of its counsel, be
necessary to increase its authorized but unissued shares· to such number of shares as shall be sufficient for such purposes. The Company agrees that its issuance of Warrants shall constitute full authority to its officers who are charged with
the issuance of Warrant Shares to issue shares of Common Stock upon the exercise of Warrants. Without limiting the generality of the foregoing, the Company will not increase the stated or par value per share, if any, of the Common Stock above the
Exercise Price in effect immediately prior to such increase in stated or par value. 
 Section 4.7 Fractional Shares.
Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not be required to issue any fraction of a share of its capital stock in connection with the exercise of Warrants, and in any case where the Registered
Holder would, except for the provisions of this Section 4.7, be entitled under the terms of Warrants to receive a fraction of a share upon the exercise of such Warrants, the Company shall, upon the exercise of such Holder’s Warrants, issue
or cause to be issued only the largest whole number of Warrant Shares issuable on such exercise (and such fraction of a share will be disregarded); provided, that if more than one Warrant is presented for exercise at the same time by the same
Holder, the number of whole Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares issuable on exercise of all such Warrants. 

Section 4.8 Listing. Prior to the issuance of any Warrant Shares upon exercise of Warrants, the Company shall secure the listing
of such shares of Common Stock or other Warrant Shares upon each national securities exchange or stock market, if any, upon which shares of Common Stock (or securities of the same class as such other Warrant Shares, if applicable) are then listed
(subject to official notice of issuance upon exercise of Warrants) and shall maintain, so long as 

  
 10 

 
any other shares of Common Stock (or, as applicable, other securities) shall be so listed, such listing of all Warrant Shares from time to time issuable upon the exercise of Warrants. 

ARTICLE V 

ADJUSTMENT OF SHARES OF COMMON STOCK PURCHASABLE 
 AND OF EXERCISE PRICE 
 The number and kind of securities or other property
purchasable upon exercise of a Warrant shall be subject to adjustment from time to time upon the occurrence, after the date hereof, of any of the following events: 
 Section 5.1 Dividends. 
 (a) In case the Company shall (1) pay a
dividend in, or make a distribution of, shares of capital stock on its outstanding Common Stock, (2) subdivide its outstanding shares of Common Stock into a greater number of such shares, or (3) combine its outstanding shares of Common
Stock into a smaller number of such shares, the total number of shares of Common Stock purchasable upon the exercise of each Warrant outstanding immediately prior thereto shall be adjusted so that the Holder shall be entitled to receive at the same
aggregate Exercise Price the number of shares of capital stock (of one or more classes) which such Holder would have owned or have been entitled to receive immediately following the happening of any of the events described above had such Warrant
been exercised in full immediately prior to the record date with respect to such event. Any adjustment made pursuant to this Subsection shall, in the case of a stock dividend or distribution, become effective as of the record date therefor and, in
the case of a subdivision or combination, be made as of the effective date thereof. If, as a result of an adjustment made pursuant to this Subsection, the Holder thereafter shall become entitled to receive shares of two or more classes of capital
stock of the Company, the Board of Directors of the Company (whose determination shall be conclusive and shall be evidenced by a Board resolution filed with the Warrant Agent) shall determine the allocation of the adjusted Exercise Price between or
among shares of such classes of capital stock. 
 (b) If at any time prior to the exercise in full of the Warrants, the Company
shall fix a record date for the issuance or making of a distribution to all holders of the Common Stock or any other Warrant Shares for which Warrants are exercisable (including any such distribution to be made in connection with a consolidation or
merger in which the Company is to be the continuing corporation) of evidences, of its indebtedness, any other securities of the Company or any cash, property or other assets (excluding a combination, reclassification or recapitalization referred to
in Section 5.1(a) and regular quarterly cash dividends) or of subscription rights, options or warrants to purchase or acquire Common Stock or Common Stock Equivalents (excluding those referred to in Section 5.1(a) (any such
event being herein called a “Special Dividend”), the Exercise Price shall be decreased immediately after the record date for such Special Dividend to a price determined by multiplying the Exercise Price then in effect by a fraction,
the numerator of which shall be the then current market price of the Common Stock on such record date less the fair market value (as determined in good faith by the Company’s Board of Directors based on the written advice of an independent
investment banking firm of national 

  
 11 

 
reputation) of the evidences of indebtedness, securities or property, or other assets issued or distributed in such Special Dividend applicable to one share of Common Stock or of such
subscription rights or warrants applicable to one share of Common Stock and the denominator of which shall be such then current market price per share of Common Stock (as so determined). Any adjustment required by this Section 5.1(b)
shall be made successively whenever such a record date is fixed and in the event that such distribution is not so made, the Exercise Price shall again be adjusted to be the Exercise Price that was in effect immediately prior to such record date.

 Section 5.2 n the event of a capital reorganization or a reclassification of the Common Stock (except as provided in
Section 5.1 or Section 5.4), any Holder, upon exercise of Warrants, shall be entitled to receive, in substitution for the Common Stock to which he would have become entitled upon exercise immediately prior to such
reorganization or reclassification, the shares (of any class or classes) or other securities or property of the Company (or cash) that he would have been entitled to receive at the same aggregate Exercise Price upon such reorganization or
reclassification if such Warrants had been exercised immediately prior to the record date with respect to such event; and in any such case, appropriate provision (as determined by the Board of Directors of the Company, whose determination shall be
conclusive and shall be evidenced by a certified Board resolution filed with the Warrant Agent) shall be made for the application of this Section 5 with respect to the rights and interests thereafter of the Holders (including but not
limited to the allocation of the Exercise Price between or among shares of classes of capital stock), to the end that this Section 5 (including the adjustments of the number of shares of Common Stock or other securities purchasable and
the Exercise Price thereof) shall thereafter be reflected, as nearly as reasonably practicable, in all subsequent exercises of the Warrants for any shares or securities or other property (or cash) thereafter deliverable upon the exercise of the
Warrants. 
 Section 5.3 Whenever the number of shares of Common Stock or other securities purchasable upon exercise of a
Warrant is adjusted as provided in this Section 6, the Company will promptly file with the Warrant Agent a certificate signed by a Chairman or co-Chairman of the Board, the Chief Executive, the President, the Chief Financial Officer or a Vice
President of the Company and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary of the Company setting forth the number and kind of securities or other property purchasable upon exercise of a Warrant, as so
adjusted, stating that such adjustments in the number or kind of shares or other securities or property conform to the requirements of this Section 5, and setting forth a brief statement of the facts accounting for such adjustments.
Promptly after receipt of such certificate, the Company, or the Warrant Agent at the Company’s request, will deliver, by first-class, postage prepaid mail, a brief summary thereof (to be supplied by the Company) to the Registered Holders and
Beneficial Holders of the outstanding Warrants; provided, however, that failure to file or to give any notice required under this Subsection, or any defect therein, shall not affect the legality or validity of any such adjustments under this
Section 6; and provided, further, that, where appropriate, such notice may be given in advance and included as part of the notice required to be given pursuant to Section 10.2 hereof. 

Section 5.4 In case of any consolidation of the Company with, or merger of the Company into, another corporation (other than a
consolidation or merger which does not result in any reclassification or change of the outstanding Common Stock), or in case of any sale or 

  
 12 

 
conveyance to another corporation of the property of the Company as an entirety or substantially as an entirety, the corporation formed by such consolidation or merger or the corporation which
shall have acquired such assets, as the case may be, shall execute and deliver to the Warrant Agent a supplemental warrant agreement providing that the Holder of each Warrant then outstanding shall have the right thereafter (until the expiration of
such Warrant) to receive, upon exercise of such Warrant, solely the kind and amount of shares of stock and other securities and property (or cash) receivable upon such consolidation, merger, sale or transfer by a Holder of the number of shares of
Common Stock of the Company for which such Warrant might have been exercised immediately prior to such consolidation, merger, sale or transfer. Such supplemental warrant agreement shall provide for adjustments which shall be as nearly equivalent as
may be practicable to the adjustments provided in this Section. The above provision of this Subsection shall similarly apply to successive consolidations, mergers, sales or transfers. 

The Warrant Agent shall not be under any responsibility to determine the correctness of any provision contained in any such supplemental
warrant agreement relating to either the kind or amount of shares of stock or securities or property (or cash) purchasable by Holders of Warrants upon the exercise of their Warrants after any such consolidation, merger, sale or transfer or of any
adjustment to be made with respect thereto, but subject to the provisions of Section 20 hereof, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, a certificate of a firm of
independent certified public accountants (who may be the accountants regularly employed by the Company) with respect thereto. 

Section 5.5 Irrespective of any adjustments in the number or kind of shares issuable upon exercise of Warrants, any Global Warrant
Certificates theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in the similar Global Warrant Certificates initially issuable pursuant to this Warrant Agreement. 

Section 5.6 For the purpose of this Section, the term “Common Stock” shall mean (a) the Common Stock or
(b) any other class of stock resulting from successive changes or reclassifications of such Common Stock consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. In the event that at any
time as a result of an adjustment made pursuant to this Section, the Holder of any Warrant thereafter surrendered for exercise 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 Common Stock contained in
this Section, and all other provisions of this Agreement, with respect to the Common Stock, shall apply on like terms to any such other shares. 
 ARTICLE VI 
 TRANSFER AND EXCHANGE 

OF WARRANTS AND WARRANT SHARES 
 Section 6.1 Registration of Transfers and Exchanges. 
 (a) Transfer and
Exchange of Global Warrant Certificates or Beneficial Interests Therein. The transfer and exchange of Global Warrant Certificates or beneficial interests 

  
 13 

 
therein shall be effected through the Depositary, in accordance with this Agreement and the procedures of the Depositary therefor. 

(b) Exchange of a Beneficial Interest in a Global Warrant Certificate for a Book-Entry Warrant. 

(i) Any Holder of a beneficial interest in a Global Warrant Certificate may, upon request, exchange such beneficial interest for a
Book-Entry Warrant. Upon receipt by the Warrant Agent from the Depositary or its nominee of written instructions or such other form of instructions as is customary for the Depositary on behalf of any person having a beneficial interest in a Global
Warrant Certificate, the Warrant Agent shall cause, in accordance with the standing instructions and procedures existing between the Depositary and Warrant Agent, the number of Warrants represented by the Global Warrant Certificate to be reduced by
the number of Warrants to be represented by the Book-Entry Warrants to be issued in exchange for the beneficial interest of such person in the Global Warrant Certificate and, following such reduction, the Warrant Agent shall register in the name of
the Holder a Book-Entry Warrant and deliver to said Holder a Warrant Statement. 
 (ii) Book-Entry Warrants issued in exchange
for a beneficial interest in a Global Warrant Certificate pursuant to this Section 6.1(b) shall be registered in such names as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct
the Warrant Agent. The Warrant Agent shall deliver such Warrant Statements to the persons in whose names such Warrants are so registered. 
 (c) Transfer and Exchange of Book-Entry Warrants. When Book-Entry Warrants are presented to the Warrant Agent with a written request: 

(i) to register the transfer of the Book-Entry Warrants; or 
 (ii) to exchange such Book-Entry Warrants for an equal number of Book-Entry Warrants of other authorized denominations, the Warrant Agent shall register the transfer or make the exchange as requested if
its customary requirements for such transactions are met; provided, however, that the Warrant Agent has received a written instruction of transfer in form satisfactory to the Warrant Agent, duly executed by the Registered Holder
thereof or by his attorney, duly authorized in writing. 
 (d) Restrictions on Exchange or Transfer of a Book-Entry Warrant
for a Beneficial Interest in a Global Warrant Certificate. A Book-Entry Warrant may not be exchanged for a beneficial interest in a Global Warrant Certificate except upon satisfaction of the requirements set forth below. Upon receipt by the
Warrant Agent of appropriate instruments of transfer with respect to a Book-Entry Warrant, in form satisfactory to the Warrant Agent, together with written instructions directing the Warrant Agent to make, or to direct the Depositary to make, an
endorsement on the Global Warrant Certificate to reflect an increase in the number of Warrants represented by the Global Warrant Certificate equal to the number of Warrants represented by such Book-Entry Warrant, then the Warrant Agent shall cancel
such Book-Entry Warrant on the Warrant Register and cause, or direct the Depositary to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Warrant Agent, the number of Warrants represented by
the Global Warrant Certificate to be increased accordingly. If no Global Warrant 

  
 14 

 
Certificates are then outstanding, the Company shall issue and the Warrant Agent shall countersign a new Global Warrant Certificate representing the appropriate number of Warrants. 

(e) Restrictions on Transfer and Exchange of Global Warrant Certificates. Notwithstanding any other provisions of this Agreement
(other than the provisions set forth in Section 6.1(f)), unless and until it is exchanged in whole for a Book-Entry Warrant, a Global Warrant Certificate may not be transferred as a whole except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 

(f) Book-Entry Warrants. If at any time: 
 (i) the Depositary for the Global Warrant Certificates notifies the Company that the Depositary is unwilling or unable to continue as Depositary for the Global Warrant Certificates and a successor
Depositary for the Global Warrant Certificates is not appointed by the Company within 90 days after delivery of such notice; or 
 (ii) the Company, in its sole discretion, notifies the Warrant Agent in writing that it elects to exclusively cause the issuance of Book-Entry Warrants under this Agreement, 

then the Warrant Agent, upon written instructions signed by an Appropriate Officer of the Company, shall register Book-Entry Warrants in the name of the
Registered Holder thereof, in an aggregate number equal to the number of Warrants represented by the Global Warrant Certificates, in exchange for such Global Warrant Certificates. 

(g) Restrictions on Transfer. No Warrants or Warrant Shares shall be sold, exchanged or otherwise transferred in violation of the
Securities Act or applicable state securities laws. 
 (h) Cancellation of Global Warrant Certificate. At such time as
all beneficial interests in Global Warrant Certificates have either been exchanged for Book-Entry Warrants, redeemed, repurchased or cancelled, all Global Warrant Certificates shall be returned to, or retained and cancelled by, the Warrant Agent,
upon written instructions from the Company satisfactory to the Warrant Agent. 
 Section 6.2 Obligations with Respect to
Transfers and Exchanges of Warrants. 
 (i) To permit registrations of transfers and exchanges, the Company shall execute
Global Warrant Certificates, if applicable, and the Warrant Agent is hereby authorized, in accordance with the provisions of Section 3.4 and this Article VI, to countersign such Global Warrant Certificates, if applicable, or
register Book-Entry Warrants, if applicable, as required pursuant to the provisions of this Article VI and for the purpose of any distribution of new Global Warrant Certificates contemplated by Section 8.2 or additional Global
Warrant Certificates contemplated by Article V. 
 (ii) All Book-Entry Warrants and Global Warrant Certificates issued
upon any registration of transfer or exchange of Book-Entry Warrants or Global Warrant 

  
 15 

 
Certificates shall be the valid obligations of the Company, entitled to the same benefits under this Agreement as the Book-Entry Warrants or Global Warrant Certificates surrendered upon such
registration of transfer or exchange. 
 (iii) No service charge shall be made to a Holder for any registration, transfer or
exchange but the Company may require payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed on the Holder in connection with any such exchange or registration of transfer. 

(iv) So long as the Depositary, or its nominee, is the registered owner of a Global Warrant Certificate, the Depositary or such nominee,
as the case may be, will be considered the sole owner or holder of the Warrants represented by such Global Warrant Certificate for all purposes under this Agreement. Except as provided in Sections 6.1(b) and (f) upon the exchange
of a beneficial interest in a Global Warrant Certificate for Book-Entry Warrants, Beneficial Holders will not be entitled to have any Warrants registered in their names, and will under no circumstances be entitled to receive physical delivery of any
such Warrants and will not be considered the Registered Holder thereof under the Warrants or this Agreement. Neither the Company nor the Warrant Agent, in its capacity as registrar for such Warrants, will have any responsibility or liability for any
aspect of the records relating to beneficial interests in a Global Warrant Certificate or for maintaining, supervising or reviewing any records relating to such beneficial interests. 

(v) Subject to Sections 6.1(b), (c) and (d), and this Section 6.2, the Warrant Agent shall, upon
receipt of all information required to be delivered hereunder, from time to time to register the transfer of any outstanding Warrants in the Warrant Register; upon surrender of Global Warrant Certificates, if applicable, representing such Warrants
at the Warrant Agent’s office as set forth in Section 10.2, duly endorsed, and accompanied by a completed form of assignment substantially in the form of Exhibit C hereto (or with respect to a Book-Entry Warrant, only such
completed form of assignment substantially in the form of Exhibit C hereto), duly signed by the Registered Holder thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, such signature to be guaranteed
by a participant in the Securities Transfer Agent Medallion Program, the Stock Exchanges Medallion Program or the New York Stock Exchange, Inc. Medallion Signature Program. Upon any such registration of transfer, a new Global Warrant Certificate or
a Warrant Statement, as the case may be, shall be issued to the transferee. 
 Section 6.3 Fractional Warrants. The
Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate for a fraction of a Warrant. 
 ARTICLE VII 
 INFORMATION 

Section 7.1 Reports. With a view to making available to Registered Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time permit a Registered Holder to sell securities of the Company to the public without registration (collectively, “Rule 144”), in the event such benefits
are required under then applicable law in order for such Registered Holder to sell Warrants or Warrant Shares without registration, the Company agrees to: 

  
 16 

 (a) make and keep public information available, as those terms are understood and defined in
Rule 144, for so long as any Warrants or Warrant Shares are outstanding; 
 (b) file with the SEC in a timely manner all reports

 ARTICLE VIII 

OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANTS 
 Section 8.1 No Rights or Liability as Stockholder; Notice to Registered Holders. Nothing contained in the Warrants shall be construed as conferring upon the Holder or his, her or its transferees
the right to vote or to receive dividends or to consent or to receive notice as a stockholder in respect of any meeting of stockholders for the election of directors of the Company or of any other matter, or any rights whatsoever as stockholders of
the Company. No provision thereof and no mere enumeration therein of the rights or privileges of the Holder shall give rise to any liability of such holder for the Exercise Price hereunder or as a stockholder of the Company, whether such liability
is asserted by the Company or by creditors of the Company. The Company shall give notice to Registered Holders by registered mail if at any time prior to the expiration or exercise in full of the Warrants, any of the following events shall occur:

 (a) the Company shall authorize the payment of any dividend payable in any securities upon shares of Common stock or
authorize the making of any distribution (other than a regular quarterly cash dividend) to all holders of Common stock; 
 (b)
the Company shall authorize the issuance to all holders of Common stock of any additional shares of Common stock or Common stock Equivalents or of rights, options or warrants to subscribe for or purchase Common stock or Common stock Equivalents or
of any other subscription rights, options or warrants; 
 (c) a dissolution, liquidation or winding up of the Company shall be
proposed; or 
 (d) a capital reorganization or reclassification of the Common stock (other than a subdivision or combination of
the outstanding Common stock and other than a change in the par value of the Common stock)· or any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the
continuing corporation and that does not result in any reclassification or change of Common stock outstanding) or in the case of any sale or conveyance to another corporation or other entity of the property of the Company as an entirety or
substantially as an entirety. 

  
 17 

 Such giving of notice shall be initiated at least fifteen (15) Business Days prior to
the date fixed as a record date or effective date or the date of closing of the Company’s stock transfer books for the determination of the stockholders entitled to such dividend, distribution or subscription rights, or for the determination of
the stockholders entitled to vote on such proposed merger, consolidation, sale, conveyance, dissolution, liquidation or winding up. Such notice shall specify such record date or the date of closing the stock transfer books, as the case may be.
Failure to provide such notice shall not affect the validity of any action taken in connection with such dividend, distribution or subscription rights, or proposed merger, consolidation, sale, conveyance, dissolution, liquidation or winding up.

 Section 8.2 Lost, Stolen, Mutilated or Destroyed Global Warrant Certificates. If any
Global Warrant Certificate is lost, stolen, mutilated or destroyed, the Company shall issue, and the Warrant Agent shall countersign and deliver, in exchange and substitution for and upon cancellation of the mutilated Global Warrant Certificate, or
in lieu of and substitution for the Global Warrant Certificate lost, stolen or destroyed, a new Global Warrant Certificate of like tenor and representing an equivalent number of Warrants, but only upon receipt of evidence and an affidavit reasonably
satisfactory to the Company and the Warrant Agent of the loss, theft or destruction of such Global Warrant Certificate, and an indemnity of the Company and Warrant Agent for any losses in connection therewith, if requested by either the Company or
the Warrant Agent, also satisfactory to them. Applicants for such substitute Global Warrant Certificates shall also comply with such other reasonable regulations and pay such other reasonable charges as the Company or the Warrant Agent may prescribe
and as required by Section 8-405 of the Uniform Commercial Code as in effect in the State of New York. 
 Section 8.3 No
Restrictive Legends. No legend shall be stamped or imprinted on any stock certificate for Warrant Shares issued upon the exercise of any Warrant and or stock certificate issued upon the direct or indirect transfer of any such Warrant Shares.

 Section 8.4 Cancellation of Warrants. If the Company shall purchase or otherwise acquire Warrants, the Global Warrant
Certificates and the Book-Entry Warrants representing such Warrants shall thereupon be delivered to the Warrant Agent, if applicable, and be cancelled by it and retired. The Warrant Agent shall cancel all Global Warrant Certificates surrendered for
exchange, substitution, transfer or exercise in whole or in part. Such cancelled Global Warrant Certificates shall thereafter be disposed of in a manner satisfactory to the Company provided in writing to the Warrant Agent. 

ARTICLE IX 

CONCERNING THE WARRANT AGENT AND OTHER MATTERS 
 Section 9.1 Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery
of the Warrant Shares upon the exercise of Warrants, but any taxes or charges in connection with the issuance of Warrants or Warrant Shares in any name other than that of the Holder of the Warrants shall be paid by such Holder; and in any such case,
the Company shall not be required to issue or deliver any Warrants or Warrant Shares until such taxes or charges shall have been paid or it is established to the Company’s satisfaction that no tax or charge is due. 

  
 18 

 Section 9.2 Resignation, Consolidation or Merger of Warrant Agent. 

(a) Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties
and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the
Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties and obligations of its predecessor
Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of
the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, rights, immunities, duties and obligations of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent, the Company
shall make, execute, acknowledge and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties and obligations.

 (b) Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall
(i) give notice thereof to the predecessor Warrant Agent and the transfer agent for the Common stock not later than the effective date of any such appointment, and (ii) cause written notice thereof to be delivered to each Registered Holder
at such holder’s address appearing on the Warrant Register. Failure to give any notice provided for in this Section 9.2(b) or any defect therein shall not affect the legality or validity of the removal of the Warrant Agent or the
appointment of a successor Warrant Agent, as the case may be. 
 (c) Merger, Consolidation or Name Change o/Warrant
Agent. 
 (i) Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any
corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement, without any further act or deed, if such person would be eligible for appointment as a
successor Warrant Agent under the provisions of Section 9.2(a). If any of the Global Warrant Certificates have been countersigned but not delivered at the time such successor to the Warrant Agent succeeds under this Agreement, any such
successor to the Warrant Agent may adopt the countersignature of the original Warrant Agent; and if at that time any of the Global Warrant Certificates shall not have been countersigned, any successor to the Warrant Agent may countersign such Global
Warrant Certificates either in the name of the predecessor Warrant Agent or in the name of the successor Warrant Agent; and in all such cases such Global Warrant Certificates shall have the full force provided in the Global Warrant Certificates and
in this Agreement. 
 (ii) If at any time the name of the Warrant Agent is changed and at such time any of the Global Warrant
Certificates have been countersigned but not delivered, the Warrant Agent whose name has changed may adopt the countersignature under its prior name; and if at that time any of the Global Warrant Certificates have not been countersigned, the Warrant
Agent may countersign such Global Warrant Certificates either in its prior name or in its changed name; and in all such cases such Global Warrant Certificates shall have the full force provided in the Global Warrant Certificates and in this
Agreement. 

  
 19

and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement. 
 Section 9.4 Liability of Warrant Agent. 
 (a) Reliance on Company
Statement. 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 statement signed by the Chief Executive Officer or Chairman of the Board of Directors of
the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement. 

(b) Indemnity. The Warrant Agent shall be liable hereunder only for its own negligence, willful misconduct or bad faith. The
Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement except
as a result of the Warrant Agent’s negligence, willful misconduct or bad faith. Notwithstanding the foregoing, the Company shall not be responsible for any settlement made without its written consent. No provision in this Agreement shall be
construed to relieve the Warrant Agent from liability for its own negligence, willful misconduct or bad faith. 
 (c)
Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to 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 to make any adjustments required under the provisions of Article V hereof or responsible for the manner, method or
amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any
Warrant Shares to be issued pursuant to this Agreement or any Warrant or as to whether any Warrant Shares will, when issued, be valid and fully paid and nonassessable. 
 Section 9.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and, among
other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for and pay to the Company all moneys received by the Warrant Agent for the purchase of Warrant Shares through the exercise of Warrants.
