 which shall then be

 which shall then be 

divided by 
 (iii) the
Market Price. 
 2.2 Issuance of Shares of Common Stock on Exercise. As promptly as practicable after the exercise of this Warrant,

such exercise in accordance with the provisions of this Warrant, including, but not limited to, the exercise of all or a portion of the remainder of this Warrant; provided, however, that if the Holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company to afford to the Holder any such rights.

process. Each party shall keep the other party apprised of the status of any communication with, and any inquiries or requests for additional information from, any Governmental Entity (or other Person regarding any of the transactions
contemplated by this Agreement) with respect to such regulatory process and shall use its respective commercially reasonable efforts to comply promptly with any such inquiry or request (and, unless otherwise prohibited by law, provide copies of any
such communications that are in writing). 
 (b) To the extent necessary to enable any Holder (including the Initial Holder) from time to
time following the Closing to exercise all, or a portion, of its then-outstanding Warrants for Warrant Shares without the filing of a notification under the HSR Act at the time of any such desired exercise, the Company shall cooperate with, and
assist, such Holder to complete (i) promptly following the Closing, an annual notification to comply with the requirements of the HSR Act, and (ii) prior to the expiration of any such annual notification, a subsequent annual notification

following receipt of the Consent Notice, the Company shall use its commercially reasonable efforts to assist the Initial Holder in selling the Warrants or the Warrant Shares promptly. 

2.7 Conditions. Notwithstanding any other provision of this Warrant, if the exercise of all or any portion of this Warrant is to be
made in connection with a registered public offering, a sale of the Company or any other transaction or event, such exercise may, at the election of the Holder, be conditioned upon consummation of such transaction or event in which case such
exercise shall not be deemed effective until the consummation of such transaction or event. 
 2.8 Expiration of Warrants. Any
unexercised Warrants shall expire and the rights of the Holders of such Warrants to purchase Warrant Shares shall terminate at 5:00 P.M. New York time, on the Expiration Date. 

3. Adjustment of Exercise Price and Warrant Shares. The Exercise Price and the number of Warrant Shares shall be subject to adjustment
from time to time upon the happening of certain events as described in this Section 3. 
 3.1 Subdivision or Combination of Stock;
Stock Dividends. If at any time or from time to time after the date hereof, the Company shall (a) subdivide (by way of stock split or otherwise) its outstanding shares of Common Stock, (b) declare a dividend or make a distribution upon
any class or series of stock of the Company payable in Common Stock or (c) combine the Common Stock (whether by stock combination, reverse stock split or otherwise) into a smaller number of shares, the Exercise Price will be adjusted by
multiplying the Exercise Price in effect immediately prior to such event by a fraction 

  
 -5- 

 
of which the numerator shall be the number of shares of Common Stock outstanding immediately prior to such event and of which the denominator shall be the number of shares of Common Stock
outstanding immediately after such event. Any adjustment made pursuant to clauses (a) or (c) of this paragraph shall become effective immediately after the effective date of such subdivision or combination and any adjustment made pursuant
to clause (b) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution. The Exercise Price, as so adjusted, shall be readjusted in the
same manner upon the happening of any successive event or events described in this Section 3.1. 
 3.2 Distribution of Rights,
Options or Warrants. If at any time or from time to time after the date hereof, the Company shall distribute to all or substantially all holders of Common Stock any rights, options or warrants entitling them, for a period of not more than 60
calendar days from the announcement date for such distribution, to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Closing Price of the Common Stock for the 10 consecutive Trading Day period ending
on, and including, the Trading Day immediately preceding the announcement date for such distribution, the Exercise Price will be adjusted by multiplying the Exercise Price in effect immediately prior to such distribution by a fraction of which the
numerator shall be the sum of (i) the number of shares of Common Stock outstanding immediately prior to such distribution and (ii) the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options
or warrants divided by the average of the Closing Price of the Common Stock over such 10 consecutive Trading Day period and of which the denominator shall be the sum of (i) the number of shares of Common Stock outstanding immediately
prior to such distribution and (ii) the total number of shares of Common Stock issuable pursuant to such rights, options or warrants. Any adjustment made pursuant to this paragraph shall become effective immediately after the record date for
the determination of stockholders entitled to receive such distribution. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, including because such rights, options or warrants were
not exercised, the Exercise Price shall be readjusted to the Exercise Price that would then be in effect had the adjustment with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of
shares of Common Stock actually delivered. If such rights, options or warrants were scheduled to be distributed prior to the Expiration Date and are not so distributed, the Exercise Price shall be readjusted to the Exercise Price that would then be
in effect if the announcement of such distribution had not occurred. 
 3.3 Distribution of Capital Stock, Evidence of Indebtedness or
Other Assets. If at any time or from time to time after the date hereof, the Company shall distribute to all or substantially all holders of Common Stock shares of capital stock, evidences of the Company’s indebtedness or other assets or
property of the Company or rights, options or warrants to acquire capital stock or other securities (excluding (i) dividends or distributions and rights, options or warrants as to which an adjustment was effected under Section 3.1 or
Section 3.2 above; (ii) dividends or distributions paid exclusively in cash described in Section 3.4 below; and (iii) Spin-Offs), the Exercise Price will be adjusted by multiplying the Exercise Price in effect immediately prior
to such distribution by a fraction of which the numerator shall be the difference between (i) the average of the Closing Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the ex-dividend date for such distribution and (ii) the fair market value (as determined in good faith by the board of directors of the Company) of the shares of capital stock, evidences of indebtedness, assets or property or rights,
options, or warrants distributed with respect to each outstanding share of Common Stock as of the open of business on the ex-dividend date for such distribution and of which the denominator shall be the average of the Closing Price of the Common
Stock over such 10 consecutive Trading Day period. Any adjustment made pursuant to this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such distribution. No adjustment
pursuant to this Section 3.3 shall result in an increase of the Exercise Price. If such distribution is scheduled to be paid or 

  
 -6- 

 
made prior to the Expiration Date and is not so paid or made, the Exercise Price shall be readjusted to the Exercise Price if such distribution had not been announced. In the case of rights,
options or warrants, if such rights, options or warrants are not so issued, or if no such rights, options or warrants are exercised prior to their expiration, the Exercise Price shall be readjusted to the Exercise Price that would then be in effect
if the announcement of such distribution had not occurred. 
 With respect to an adjustment pursuant to this Section 3.3 where there
has been an announcement of a Spin-Off, the Exercise Price will be adjusted by multiplying the Exercise Price in effect immediately prior to such distribution by a fraction of which the numerator shall be the average of the Closing Price of Common
Stock over the first 10 consecutive Trading Day period commencing on, and including, the ex-dividend date for the Spin-Off and of which the denominator shall be the sum of (i) the average of the Closing Price of the Common Stock over such 10
consecutive Trading Day period and (ii) the average of the Closing Price of the capital stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over such 10 consecutive Trading Day
period. 
 The adjustment to the Exercise Price under the preceding paragraph of this Section 3.3 will be determined on the last day of
the 10 consecutive Trading Day period commencing on, and including, the ex-dividend date for the Spin-Off, but will be given effect immediately after the record date for the Spin-Off. 

3.4 Cash Dividend. If at any time or from time to time after the date hereof, the Company shall distribute to all or substantially all
holders of Common Stock an extraordinary cash dividend or distribution (which shall not include regular quarterly cash dividends payable on the Common Stock as approved by the board of directors of the Company), the Exercise Price will be adjusted
by multiplying the Exercise Price in effect immediately prior to such dividend or distribution by a fraction of which the numerator shall be the difference between (i) the Closing Price of the Common Stock on the Trading Day immediately
preceding the ex-dividend date for such dividend or distribution and (ii) the amount in cash per share that the Company pays or distributes to all or substantially all holders of the Common Stock and of which the denominator shall be the
Closing Price of the Common Stock on the Trading Day immediately preceding the ex-dividend date for such dividend or distribution. Any adjustment made pursuant to this paragraph shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution. No adjustment pursuant to this Section 3.4 shall result in an increase of the Exercise Price. If any dividend or distribution described in this Section 3.4 is
scheduled to be paid or made prior to the Expiration Date but is not so paid or made, the Exercise Price shall be readjusted to the Exercise Price that would then be in effect if such dividend or distribution had not been declared. 

3.5 Payment for Tender or Exchange Offer for Common Stock. If at any time or from time to time after the date hereof, the Company or
any of its subsidiaries shall make a payment in respect of a tender or exchange offer for the Common Stock, and if the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing
Price of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Exercise Price
will be adjusted by multiplying the Exercise Price in effect immediately prior to such payment by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately prior to the time such tender or exchange offer
expires (prior to giving effect to such tender or exchange offer) multiplied by the average of the Closing Price of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the
Offer Expiration Date and of which the denominator shall be the sum of (i) the aggregate value of all cash and any other consideration (as determined in good faith by the board of 

  
 -7- 

 
directors of the Company) paid or payable for shares of Common Stock purchased in such tender or exchange offer and (ii) the number of shares of Common Stock outstanding immediately after
the time such tender or exchange offer expires (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer) multiplied by the average of the Closing Price of the Common Stock over the
10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Offer Expiration Date. 
 The adjustment
to the Exercise Price under the preceding paragraph of this Section 3.5 shall be determined at the close of business on the tenth Trading Day immediately following, but excluding, the Offer Expiration Date but will be given effect at the open
of business on the Trading Day next succeeding the Offer Expiration Date. If the Trading Day next succeeding the Offer Expiration Date is less than 10 Trading Days prior to, and including, the Exercise Date, then references within this
Section 3.5 to 10 Trading Days shall be deemed to be replaced, solely in respect of such Exercise Date, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to,
and including, the Exercise Date. No adjustment pursuant to this Section 3.5 shall result in an increase of the Exercise Price. 
 3.6
Upon Reclassifications, Reorganizations, Consolidations or Mergers. In the event of any capital reorganization of the Company, any reclassification of the stock of the Company (other than a change in par value or from par value to no par
value or from no par value to par value or as a result of a stock dividend or subdivision, split up or combination of shares), or any consolidation or merger of the Company with or into another Person (where the Company is not the surviving Person
or where there is a change in or distribution with respect to the Common Stock), each Warrant shall after such reorganization, reclassification, consolidation, or merger be exercisable for the kind and number of shares of stock or other securities
or property of the Company or of the successor Person resulting from such consolidation or surviving such merger, if any, to which the holder of the number of shares of Common Stock deliverable (immediately prior to the time of such reorganization,
reclassification, consolidation or merger) upon exercise of such Warrant would have been entitled upon such reorganization, reclassification, consolidation or merger. The provisions of this clause shall similarly apply to successive reorganizations,
reclassifications, consolidations, or mergers. The Company shall not effect any such reorganization, reclassification, consolidation or merger unless, prior to the consummation thereof, the successor Person (if other than the Company) resulting from
such reorganization, reclassification, consolidation or merger, shall assume, by written instrument, the obligation to deliver to the Holders of the Warrant such shares of stock, securities or assets, which, in accordance with the foregoing
provisions, such Holders shall be entitled to receive upon such exercise. 
 3.7 Upon Issuance of Common Stock. If the Company shall,
at any time or from time to time after the Original Issue Date, issue any shares of Common Stock, options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock, or options to
purchase or rights to subscribe for such convertible or exchangeable securities approved by the board of directors of the Company (other than Excluded Stock) without consideration or for consideration per share less than 95% of the Closing Price per
share of the Common Stock immediately prior to the earlier of (i) the date of such issuance or (ii) the date on which a binding agreement is entered into by the Company in respect of such issuance (the “Issuance Price”), then
such Exercise Price shall forthwith be lowered to a price equal to the price obtained by multiplying: 
 (i) the Exercise Price in effect
immediately prior to the issuance of such Common Stock, options, rights or securities by 
 (ii) a fraction of which (x) the numerator
shall be the sum of (i) the number of shares of Common Stock outstanding on a fully-diluted basis 

  
 -8- 

 
immediately prior to such issuance and (ii) the aggregate consideration to be received upon the issuance of the Common Stock divided by the Issuance Price and (y) the denominator shall
be the number of shares of Common Stock outstanding on a fully diluted basis immediately after such issuance. 
 For purposes of this
Section 3.7, “fully diluted basis” shall be determined in accordance with the treasury stock method of computing fully diluted earnings per share in accordance with Generally Accepted Accounting Principles in the United States. 

3.8 Upon Acquisition of Common Stock. If the Company shall, at any time or from time to time after the Original Issue Date, directly or
indirectly, redeem, purchase or otherwise acquire any shares of Common Stock, options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock, or options to purchase or rights
to subscribe for such convertible or exchangeable securities, for a consideration per share greater than the Closing Price (plus, in the case of such options, rights, or securities, the additional consideration required to be paid to the Company
upon exercise, conversion or exchange) per share of Common Stock immediately prior to such event, then the Exercise Price shall forthwith be lowered to a price equal to the price obtained by multiplying: 

(i) the Exercise Price in effect immediately prior to such event by 

(ii) a fraction of which (x) the denominator shall be the Closing Price per share of Common Stock immediately prior to such event and
(y) the numerator shall be the result of dividing: 
 (A) (1) the product of (a) the number of shares of Common Stock outstanding
on a fully diluted basis and (b) the Closing Price per share of Common Stock, in each case immediately prior to such event, minus (2) the aggregate consideration paid by the Company in such event (plus, in the case of such options, rights,
or convertible or exchangeable securities, the aggregate additional consideration to be paid by the Company upon exercise, conversion or exchange), by 

(B) the number of shares of Common Stock outstanding on a fully diluted basis immediately after such event. 

Notwithstanding anything in this Section 3.8, this Warrant shall not be adjusted pursuant to this Section 3.8 if it is already
subject to adjustment pursuant to Section 3.5. 
 3.9 Provisions Applicable to Adjustments. For the purposes of any adjustment of
the Exercise Price pursuant to Section 3.7 or 3.8, the following provisions shall be applicable: 
 (i) In the case of the issuance of
Common Stock for cash in a public offering or private placement, the consideration shall be deemed to be the amount of cash paid therefore after deducting therefrom an discounts, commissions or placement fees payable by the Company to any
underwriter or placement agent in connection with the issuance and sale thereof. 

  
 -9- 

 (ii) In the case of the issuance of Common Stock for a consideration in whole or in part other
than cash, the consideration other than cash shall be deemed to be the fair market value thereof. 
 (iii) In the case of the issuance of
options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock, or options to purchase or rights to subscribe for such convertible or exchangeable securities (except for
options to acquire Excluded Stock): 
 (A) the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options
to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subparagraphs
(i) and (ii) above), if any, received by the Company upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby; 

(B) the aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange for any such convertible or
exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities,
options, or rights were issued and for a consideration equal to the consideration received by the Company for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus
the additional consideration, if any, to be received by the Company upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in
paragraphs (i) and (ii) above); 
 (C) on any change in the number of shares or exercise price of Common Stock deliverable upon
exercise of any such options or rights or conversions of or exchanges for such securities, other than a change resulting from the anti dilution provisions thereof, the Exercise Price shall forthwith be readjusted to such Exercise Price as would have
been obtained had the adjustment made upon the issuance of such options, rights or securities not converted prior to such change or options or rights related to such securities not converted prior to such change been made upon the basis of such
change; 
 (D) upon the expiration of any options to purchase or rights to subscribe for Common Stock which shall not have been exercised,
the Exercise Price computed upon the original issue thereof (or upon the occurrence of a record date with respect 

  
 -10- 

 
thereto), and any subsequent adjustments based thereon, shall, upon such expiration, be recomputed as if the only additional shares of Common Stock issued were the shares of Common Stock, if any
actually issued upon the exercise of such options to purchase or rights to subscribe for Common Stock, and the consideration received therefor was the consideration actually received by the Company for the issue of the options to purchase or rights
to subscribe for Common Stock that were exercised, plus the consideration actually received by the Company upon such exercise; and 
 (E) no
further adjustment of the Exercise Price adjusted upon the issuance of any such options, rights, convertible securities or exchangeable securities shall be made as a result of the actual issuance of Common Stock on the exercise of any such rights or
options or any conversion or exchange of any such securities. 
 3.10 Minimum Adjustment of Exercise Price. If the amount of any
adjustment of the Exercise Price required pursuant to this Section 3 would be less than one-tenth (1/10) of one percent (1%) of the Exercise Price in effect at the time such adjustment is otherwise so required to be made, such amount
shall be carried forward and adjustment with respect thereto made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate to at least one tenth
(1/10) of one percent (1%) of such Exercise Price. Notwithstanding the foregoing, all carried forward adjustments not yet made shall be made immediately prior to any exercise, whether full or partial, of this Warrant. 

3.11 Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to this Section 3, the number of
Warrant Shares that will be received upon exercise of this Warrant shall be increased or decreased proportionally, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the
same as the aggregate Exercise Price in effect immediately prior to such adjustment. 
 3.12 Limitation on Corporate Actions Requiring an
Adjustment to the Exercise Price. 
 (a) The Company hereby agrees not to undertake any action or enter into any agreement that would
result in the Company being required under Section 3 to adjust the Exercise Price below the Initial Exercise Price unless either (a) the Company has previously obtained stockholder approval to issue the Warrant Shares for less than the
greater of book or market value of the stock (each as determined under NASDAQ Listing Rule 5635(d)(ii)), or (b) notwithstanding Section 2.1 hereof, the Company, at the time of exercise of the Warrant, agrees to issue to the Holder
(i) no more than the maximum number of Warrant Shares that can be issued without the requirement of approval of the Company’s stockholders under NASDAQ Rule 5635, and (ii) cash in lieu of such additional Warrant Shares that would
otherwise be issued to the Holder at the time of exercise (calculated based on the Market Price on the date when such Warrant Shares would otherwise be required to be issued). 

3.13 Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Exercise Price and number of Warrant
Shares pursuant to this Section 3, this Warrant shall, without any action on the part of the Holder, be adjusted in accordance with this Section 3, and the Company, at its expense, promptly shall compute such adjustment or readjustment in
accordance with the terms hereof and prepare and furnish to the Holder a certificate setting forth such adjustment or

 5.2 Taking of Record. In the case of all dividends or other distributions by
the Company to the holders of its Common Stock with respect to which any provision hereof refers to the taking of a record of such holders, the Company will in each such case take such a record and will take such record as of the close of business

transfer books so as to result in preventing or delaying the exercise or transfer of any Warrant.

cash, securities or other property, if any, which may be purchased by the Holder upon exercise of this Warrant at the time of its surrender. 

6. Transfer Provisions, etc. 

6.1 Legends. This Warrant (unless registered under the Securities Act) and all shares of Warrant Shares issued upon exercise of this
Warrant (unless registered under the Securities Act) issued in certificated form shall be stamped or imprinted, and each book-entry position shall include a notation, with a legend in substantially the following form: 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
OFFERED OR SOLD IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, REGISTRATION UNDER SAID ACT.” 

6.2 Mechanics of Transfer. 

(a) Any transfer of all or any portion of this Warrant (and the Warrant Shares), or of any interest herein or therein, shall be effected by
surrendering this Warrant to the Company at its principal office, together with a duly executed form of assignment, substantially in the form attached hereto and, if reasonably requested by the Company, a representation in writing that such transfer
is pursuant to an effective registration statement under the Securities Act of 1933, as amended, or pursuant to an available exemption from, or in a transaction not subject to, registration under the Securities Act of 1933, as amended. In the event
of any such transfer of this Warrant, subject to compliance with applicable federal and state securities laws, the Company shall issue as promptly as practicable after the transfer request is delivered, and in any event within three
(3) business days, a new Warrant or Warrants of like tenor to the transferee(s), representing, in the aggregate, the right to purchase the same number of Warrant Shares and cash, securities or other property, if any, which may be purchased by
the Holder upon exercise of this Warrant at the time of its surrender, in accordance with 

  
 -13- 

 
Section 2 hereof. Each new certificate evidencing the Warrant and/or Warrant Shares so transferred shall bear the appropriate restrictive legends set forth in Section 6.1 hereof, except
that such certificate shall not bear such restrictive legend, if such legend is not required in order to establish or assist in compliance with any provisions of the Securities Act or any applicable state securities laws. Moreover, the Company
shall, at the time of any transfer of this Warrant, upon the request of the Holder, acknowledge in writing its continuing obligation to afford to the Holder any rights to which the Holder shall continue to be entitled after such transfer in
accordance with the provisions of this Warrant, including, but not limited to, the exercise of all or a portion of the remainder of this Warrant; provided, however, that if the Holder shall fail to make any such request, such failure shall not
affect the continuing obligation of the Company to afford to the Holder any such rights. 
 (b) In the event of any transfer of all or any
portion of this Warrant in accordance with Section 6.2(a) above, the Company shall issue (i) a new warrant of like tenor to the transferee, representing the right to purchase the number of Warrant Shares, and cash, securities or other
property, if any, which were purchasable by the Holder of the transferred portion of this Warrant at the time of said transfer, and (ii) a new warrant of like tenor to the Holder, representing the right to purchase the number of Warrant Shares,
if any, and cash, securities or other property, if any, purchasable by the Holder of the portion of this Warrant not transferred. Until this Warrant or any portion thereof is transferred on the books of the Company, the Company may treat the Holder
as the absolute holder of this Warrant and all right, title and interest therein for all purposes, notwithstanding any notice to the contrary. 

6.3 No Restrictions on Transfer. Subject to compliance with applicable federal and state securities laws, this Warrant and any portion
hereof, the Warrant Shares and the rights hereunder may be transferred by the Holder in its sole discretion at any time and to any Person or Persons, including, without limitation, Affiliates and affiliated groups of such Holder, without the consent
of the Company. 
 6.4 Warrant Register. The Company shall keep at its principal office a register for the registration, and
registration of transfers, of the Warrants. The name and address of each Holder of one or more of the Warrants, each transfer thereof and the name and address of each transferee of one or more of the Warrants shall be registered in such register.
The Company shall give to any Holder of a Warrant promptly upon request therefor, a complete and correct copy of the names and addresses of all registered Holders of the Warrants. 

6.5 Lost, Stolen or Destroyed Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of a customary affidavit of the Holder and customary unsecured indemnity agreement, or, in the case of mutilation, upon surrender of this Warrant,
the Company at its expense will execute and deliver, or will instruct its transfer agent to execute and deliver, a new Warrant of like tenor and date and representing the same rights represented by such lost, stolen, destroyed or mutilated warrant
and any such lost, stolen. mutilated or destroyed Warrant thereupon shall become void. 
 7. General. 

7.1 Authorized Shares, Reservation of Shares for Issuance. (a) The Company shall at all times reserve and keep available for
issuance upon the exercise of the Warrants such number of its authorized but unissued shares of Common Stock as will be required for issuance of the Warrant Shares. All Warrant Shares issuable pursuant to the terms hereof, when issued upon exercise
of this Warrant in accordance with the terms hereof, shall be duly and validly issued and fully paid and nonassessable, not subject to preemptive rights and shall be free and clear of all liens, taxes, charges and other encumbrances or restrictions
on sale (other than those set forth herein). Before taking any action that would result in an 

  
 -14- 

 
adjustment in the number of shares of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or
consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction over such action. If any Warrant Shares required to be reserved for issuance upon exercise of Warrants require registration or qualification with any
Governmental Entity under any federal or state law (other than under the Securities Act or any state securities law) before such shares may be so issued, the Company will in good faith and as expeditiously as possible and at its expense endeavor to
cause such shares to be duly registered. 
 (b) Before taking any action that would cause an adjustment reducing the Exercise Price below
the then par value (if any) of the shares of Warrant Shares deliverable upon exercise of the Warrant or that would cause the number of shares of Warrant Shares issuable upon exercise of the Warrant to exceed (when taken together with all other
Outstanding shares of Common Stock) the number of shares of Common Stock that the Company is authorized to issue, the Company will take any corporate action that, in the opinion of its counsel, is necessary in order that the Company may validly and
legally issue the full number of fully paid and nonassessable Warrant Shares issuable upon exercise of the Warrant at such adjusted exercise price. 

7.2 No Impairment. The Company shall not by any action, including, without limitation, amending its charter documents or through any
reorganization, reclassification, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other similar voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder against impairment. Without limiting the generality of the
foregoing, the Company shall take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Warrant Stock upon the exercise of this Warrant, free and clear of
all liens, taxes, charges and other encumbrances or restrictions on sale (other than those set forth herein), and shall use its best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant. 
 7.3 No Rights as
Stockholder. The Holder shall not be entitled to vote or to receive dividends (except as expressly provided herein) or to be deemed the holder of Common Stock that may at any time be issuable upon exercise of this Warrant for any purpose
whatsoever, nor shall anything contained herein be construed to confer upon the Holder any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting
thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance or reclassification of stock, change of par value or change of stock to no par value, consolidation, merger or conveyance or otherwise), or
to receive notice of meetings (except to the extent otherwise provided in this Warrant), or to receive dividends or subscription rights, until the Holder shall have exercised this Warrant and been issued Warrant Shares in accordance with the
provisions hereof and continues to hold Warrant Shares. 
 7.4 No Recourse. This Warrant may only be enforced against, and any action
that may be based upon, arise out of or relate to this Warrant, or the negotiation, execution or performance of this Warrant may only be made against the entities that are expressly identified as parties hereto (or their successors and permitted
assigns, or any third party beneficiaries hereto) and none of (a) the Holder’s or any of its Affiliates’ or any direct or indirect stockholders (other than the Holder), members, managers, directors, officers, employees, agents,
representatives or assignees of any of the foregoing (collectively, the “Holder Related Parties”) or (b) the Company’s or any of its Affiliates’ stockholders (other than the Company, or as otherwise contemplated by
this Agreement), members, managers, directors, officers, 

  
 -15- 

 
employees, agents, representatives or assignees of any of the foregoing (collectively, the “Company Related Parties”), in each case, shall have any liability for any obligations
or liabilities of the other parties to this Warrant or for any action (whether in tort, contract or otherwise) based on, in respect of, or by reason of, the transactions contemplated hereby or in respect of any oral representations made or alleged
to be made in connection herewith. Without limiting the rights of the parties hereunder against the other parties to this Warrant, in no event shall (i) the Company or any of its Affiliates, and the Company agrees not to and to cause its
Affiliates not to, seek to enforce this Warrant against, commence any actions for breach of this Warrant against, or seek to recover monetary damages from, any Holder Related Party, or (ii) the Holder or any of its Affiliates, and the Holder
agrees not to and to cause its Affiliates not to, seek to enforce this Warrant against, commence any actions for breach of this Warrant against, or seek to recover monetary damages from, any Company Related Party.

 8. Amendment and Waiver. No failure or delay of the Holder in exercising any power or right hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of
any other right or power. The rights and remedies of the Holder are cumulative and not exclusive of any rights or remedies which it would otherwise have. Any term of this Warrant may be amended or waived upon the written consent of the Company and
the holders of at least 50% of the Warrant Shares issuable pursuant to the Warrants; provided that any provision that applies to the Initial Holder only may only be amended or waived upon the written consent of the Initial Holder. 

9. Governing Law. This Warrant shall be governed by and construed in accordance with the laws of the State of New York without giving
effect to any principles of conflicts or choice of law that would result in the application of the laws of any other jurisdiction. Any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in
connection with, this Warrant or the transactions contemplated hereby may only be brought in any federal or state court located in the County and State of New York, and the parties hereby consent to the exclusive jurisdiction of such courts (and of
the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waive, to the fullest extent permitted by law, any objection now or hereafter to the laying of the venue of any such suit, action or proceeding in any
such court or that any such suit, action or proceeding which is brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or
without the jurisdiction of any such court. Without limiting the foregoing, the parties agrees that service of process on a party as provided in Section 15(a) shall be deemed effective service of process on such party. EACH OF THE PARTIES
HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS WARRANT. 

10. Covenants To Bind Successor and Assigns. All covenants, stipulations, promises and agreements in this Warrant contained by or on
behalf of the Company shall bind its successors and assigns, whether so expressed or not. 
 11. Severability. In case any one or
more of the provisions contained in this Warrant shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.
The parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as reasonably possible to that of the invalid, illegal or
unenforceable provisions. 
 12. Construction. The definitions of this Warrant shall apply equally to both the singular and the
plural forms of the terms defined. Wherever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The section and paragraph headings used herein are for convenience of reference only, are not part
of this Warrant and are not to affect the construction of or be taken into consideration in interpreting this Warrant. 

  
 -17- 

 13. Remedies. The Holder, in addition to being entitled to exercise all rights granted by
law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. Accordingly, the Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the holder, by
vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Warrant will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Warrant, that the Holder shall be entitled, in addition to all other available remedies at law or in equity, and in addition to the penalties assessable herein, to an injunction or
injunctions restraining, preventing or curing any breach of this Warrant and to enforce specifically the terms and provisions thereof, without the necessity of showing economic loss and without any bond or other security being required. In any
action or proceeding brought to enforce any provision of this Warrant or where any provision hereof is validly asserted as a defense, the successful party to such action or proceeding shall be entitled to recover reasonable attorneys’ fees in
addition to any other available remedy. 
 14. Entire Agreement. This Warrant, the Warrants Purchase Agreement and the Investor
Rights Agreement constitute the entire agreement between the parties hereto and thereto respecting the subject matter hereof and thereof and supersede all prior agreements, negotiations, understandings, representations and statements respecting the

Registration Statement or the commencement of a Fully Marketed Underwritten

Offering past the date that is the earliest of (a) the date upon which any disclosure of a matter the Board has determined would not be in the best interest of the Company to be disclosed is
disclosed to the public or ceases to be material, (b) forty-five (45) days after the date upon which the Board has determined such matter should not be disclosed and (c) such date that, if such postponement continued, would result in

not available to the Company for the offer and sale of the Registrable Securities, the Registrable Securities may be registered separate from a Shelf Registration Statement. Any time after the date hereof and subject to foregoing sentence and
Section 2(a), any Demand Stockholder may request registration for resale under the Securities Act of all or part of the Registrable Securities pursuant to a Registration Statement separate from the Shelf Registration Statement (a “Demand
Registration”). As promptly as practicable after such request, but in any event within fifteen (15) days of such request by a Demand Stockholder, the Company shall file a registration statement registering for resale such number of shares
of Registrable Securities held by such Demand Stockholders as requested to be so registered (including the Prospectus, amendments and supplements to such registration statement or Prospectus, including pre- and post-effective amendments, all
exhibits thereto and all material incorporated by reference or deemed to be incorporated by reference, if any, in such registration statement, a “Demand Registration Statement”). In connection with each such Demand Registration involving

 (b) Number of Demand Registrations.
The Demand Stockholders, collectively, will be entitled to request a total of three (3) Demand Registrations pursuant to Section 3(a), minus the number of Fully Marketed Underwritten Offerings completed off of the Shelf Registration
Statement. A registration shall not count as one of the permitted Demand Registrations pursuant to Section 3(a)(i) until the related Demand Registration Statement has become effective, (ii) if the Demand Stockholders are not able to
register and sell at least 50% of the aggregate Registrable Securities requested to be included in such registration, (iii) if there was not Full Cooperation in connection therewith or (iv) in the case of a Demand Registration that would
be the last permitted Demand Registration requested pursuant to Section 3(a), if the Demand Stockholders are not able to register and sell all of the Registrable Securities requested to be included in such registration. 

  
 7 

 (c) Priority on Demand Registrations. If a Demand Registration pursuant to this
Section 3 involves an underwritten offering and the managing underwriter shall advise the Company that in its opinion the number of securities requested to be included in such registration exceeds the number that can be sold in such offering
without having an adverse effect on such offering, including the price at which such securities can be sold, then the Company shall include in such registration the maximum number of securities that such underwriter advises can be so sold without
having such effect, allocated (i) first, to Registrable Securities requested by the Demand Stockholders to be included in such registration and (ii) second, among all securities requested to be included in such registration by any other
Persons (including securities to be sold for the account of the Company) allocated among such Persons in such manner as they may agree. 

(d) Restrictions on Demand Registrations. The Company may postpone the filing or the effectiveness of a Demand Registration Statement
if, based on the good faith judgment of the Company’s Board, such postponement is necessary in order to avoid premature disclosure of a matter the Board has determined would not be in the best interest of the Company to be disclosed at such
time; provided, however, that the Demand Stockholder requesting such Demand Registration Statement shall be entitled, at any time after receiving notice of such postponement and before such Demand Registration Statement becomes effective, to
withdraw such request and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations. The Company shall provide written notice to the Demand Stockholders of (x) any postponement of the
filing or effectiveness of a Demand Registration Statement pursuant to this Section 3(d), (y) the Company’s decision to file or seek effectiveness of such Demand Registration Statement following such postponement and (z) the
effectiveness of such Demand Registration Statement. The Company may defer the filing or effectiveness of a particular Demand Registration Statement pursuant to this Section 3(d) only once during any 12-month period. Notwithstanding the
provisions of this Section 3(d), the Company may not postpone the filing or effectiveness of a Demand Registration Statement past the date that is the earliest of (a) the date upon which any disclosure of a matter the Board has determined
would not be in the best interest of the Company to be disclosed is disclosed to the public or ceases to be material, (b) forty-five (45) days after the date upon which the Board has determined such matter should not be disclosed and
(c) such date that, if such postponement continued, would result in there being more than sixty (60) days in the aggregate in any 12 month period during which the filing or effectiveness of one or more Registration Statements has been so
postponed. The period during which filing or effectiveness is so postponed hereunder is referred to as a “Demand Delay Period.” 

(e) Effective Period of Demand Registrations. After any Demand Registration filed pursuant to this Agreement has become effective, the
Company shall use its reasonable best efforts to keep such Demand Registration Statement effective for a period of at least one hundred and eighty (180) days from the date on which the SEC declares such Demand Registration Statement effective
plus the duration of any Demand Delay Period and any Blackout Period, or such shorter period that shall terminate when all of

successor forms thereto), whether for its own account or for the account of one or more securityholders of the Company which permits the inclusion of a Stockholder’s Registrable Securities (a “Piggyback Registration”), the Company
shall give prompt written notice to each Stockholder of its intention to effect such sale or registration and, subject to Sections 4(b) and 4(c), shall include in such transaction all Registrable Securities with respect to which the Company has
received a written request from the Stockholders for inclusion therein within fifteen (15) days after the receipt of the Company’s notice. The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at
any time in its sole discretion, without prejudice to the Stockholders’ right to immediately request a Demand Registration or Shelf Registration Statement hereunder. A Piggyback Registration shall not be considered a Demand Registration for
purposes of Section 3 of this Agreement or a Shelf Registration Statement for purposes of Section 2 of this Agreement. 
 (b)
Priority on Primary Registrations. If a Piggyback Registration is initiated as an underwritten primary registration on behalf of the Company, and the managing underwriter advises the Company in writing that in its opinion the number of
securities requested to be included in such registration exceeds the number that can be sold in such offering without having an adverse effect on such offering, including the price at which such securities can be sold, then the Company shall include
in such registration the maximum number of shares that such underwriter advises can be so sold without having such effect, allocated (i) first, to the securities the Company proposes to sell and (ii) second, to the Registrable Securities
and other securities requested to be included in such registration by the Stockholders and other security holders of the Company, pro rata among the holders of such securities on the basis of the number of shares, including Registrable Securities,
requested to be registered by such holders so long as no other registration rights remain outstanding. 
 (c) Priority on Secondary
Registrations. If a Piggyback Registration is initiated as an underwritten registration on behalf of a holder of the Company’s securities other than Registrable Securities and such registration permits the inclusion of a Stockholder’s
Registrable Securities, and the managing underwriter advises the Company in writing that in its opinion the number of securities requested to be included in such registration exceeds the number that can be sold in such offering without having an
adverse effect on such offering, including the price at which such securities can be sold, then the Company 

  
 9 

 
shall include in such registration the maximum number of shares that such underwriter advises can be so sold without having such effect, allocated (i) first, to the securities requested to
be included therein by the holder(s) requesting such registration and (ii) the Registrable Securities and other securities requested to be included in such registration by the Stockholders, other security holders and the Company, pro rata among
the Stockholders, such other security holders and the Company on the basis of the number of shares requested to be registered by them so long as no other registration rights remain outstanding.

to any Person the right, other than as set forth herein and except to employees of the Company with respect to registrations on Form S-8 (or any successor forms thereto), to request the Company to register any securities of the Company except such
rights as are not more favorable than or inconsistent with the rights granted to the Stockholders and that do not adversely affect the priorities set forth herein of the Stockholders.

the underwriter managing the offering otherwise agrees to a shorter period. 
 (b) So long as the Initial Stockholder has any designees on
the Company’s Board, if (i) the Company proposes to offer and sell any of its common equity securities for its own account in an underwritten public offering and (ii) reasonably requested by the lead managing underwriter, the Initial
Stockholder shall, only upon providing its prior consent (such consent not to be unreasonably withheld), enter into a reasonable and customary 

  
 10

agreement signed by any director, officer or stockholder of the Company.

(30) days in the case of an event described in Section 3(d)) until such Stockholder is advised in writing by the Company that the use of the Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as
contemplated by Section 8(a) hereof; provided, however, that such postponement of sales of Registrable Securities by such Stockholder shall not exceed forty-five (45) days in the aggregate in any six-month period. If the
Company shall give the Stockholders any Suspension Notice, the Company 

  
 15 

 
shall extend the period of time during which the Company is required to maintain the applicable Registration Statements effective pursuant to this Agreement by the number of days during the
period from and including the date of the giving of such Suspension Notice to and including the date the Stockholders either are advised by the Company that the use of the Prospectus may be resumed or receive copies of the supplemented or amended
Prospectus contemplated by Section 8(a) (a “Blackout Period”). In any event, the Company shall not be entitled to deliver more than a total of three (3) Suspension Notices in any twelve (12) month period. 

(f) The Company shall not permit any officer, manager, underwriter, broker or any other person acting on behalf of the Company to use any free
writing prospectus (as defined in Rule 405 under the Securities Act) in connection with any registration statement covering Registrable Securities, without the prior written consent of the Stockholders and any underwriter. 

(g) In no event shall the Company be required to effect more than one underwritten offering hereunder within any six-month period, whether as
a Fully Marketed Underwritten Offering pursuant to the Shelf Registration Statement or, in the event the Company is not eligible for registration under the Shelf Registration Statement, as an underwritten offering pursuant to a Demand Registration.

  

	 	9.	Registration Expenses. 

 (a) All expenses incident to the Company’s performance of
or compliance with this Agreement, including, without limitation, all registration and filing fees (including SEC registration fees and FINRA filing fees), fees and expenses of compliance with securities or blue sky laws, listing application fees,
printing expenses, transfer agent’s and registrar’s fees, cost of distributing Prospectuses in preliminary and final form as well as any supplements thereto, and fees and disbursements of counsel for the Company and all accountants and
other Persons retained by the Company (all such expenses being herein called “Registration Expenses”) (but not including any underwriting discounts or commissions or transfer taxes, if any, attributable to the sale of Registrable
Securities), shall be borne by the Company. In addition, the Company shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any
annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which they are to be listed. 

(b) In connection with each registration initiated hereunder (whether a Demand Registration, Shelf Registration Statement or a Piggyback
Registration), the Company shall pay, or shall reimburse the Stockholders for, the reasonable fees and disbursements of one law firm chosen by the Stockholders as their counsel. 

(c) The obligation of the Company to bear the expenses described in Section 9(a) and to pay or reimburse the Stockholders for the
expenses described in Section 9(b) shall apply irrespective of whether a registration, once properly demanded, if applicable, becomes effective, is withdrawn or suspended, is converted to another form of registration and irrespective of when
any of the foregoing shall occur. 

  
 16 

	 	10.	Indemnification. 

 (a) The Company shall indemnify, to the fullest extent permitted by
law, each Stockholder and its officers, directors, employees and Affiliates and each Person who controls a Stockholder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses arising out of or based
upon any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any “issuer free writing prospectus” (as defined in Securities Act Rule 433) or any amendment
thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or any violation or alleged violation by the Company of the Securities Act,
the Exchange Act or applicable “blue sky” laws, except insofar as the same are made in reliance and in conformity with information relating to a Stockholder furnished in writing to the Company by such Stockholder expressly for use therein.
In connection with an underwritten offering, the Company shall indemnify such underwriter(s), their officers, employees and directors and each Person who controls such underwriter(s) (within the meaning of the Securities Act) to the same extent as
provided above with respect to the indemnification of the Stockholders. 
 (b) In connection with any Registration Statement in which a
Stockholder is participating, such Stockholder shall furnish to the Company in writing such information as the Company reasonably determines, based on the advice of counsel, is required to be included in, any such Registration Statement or
Prospectus and, shall indemnify, to the fullest extent permitted by law, the Company, its officers, employees, directors, Affiliates, and each Person who controls the Company (within the meaning of the Securities Act) against all losses, claims,
damages, liabilities and expenses arising out of or based upon any untrue or alleged untrue statement of material fact contained in the Registration Statement, Prospectus, preliminary Prospectus, any “free writing prospectus” (as defined
in Securities Act Rule 433) or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that
the same are made in reliance and in conformity with information relating to such Stockholder furnished in writing to the Company by such Stockholder expressly for use therein. 

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with
respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to

  
 17 

 
such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party
shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a
claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any
indemnified party there may be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such claim. Failure to give prompt
written notice shall not release the indemnifying party from its obligations hereunder. 
 (d) The indemnification provided for under this
Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of securities. 

(e) If the indemnification provided for in or pursuant to this Section 10 is due in accordance with the terms hereof, but is held by a
court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party
on the other in connection with the statements or omissions that result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying party on the one hand and
of the indemnified Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party, and by such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. In no event shall the liability of a
Stockholder be greater in amount than the amount of net proceeds received by such Stockholder upon such sale. 
  

	 	11.	Rule 144. 

 The Company covenants that it will file the reports required to be filed by
it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder, and it will take such further action as the Stockholders may reasonably request to make available adequate current public information with
respect to the Company meeting the current public information requirements of Rule 144(c) under the Securities Act, to the extent required to enable the Stockholders to sell Registrable Securities 

  
 18 

 
without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or
(ii) any similar rule or regulation hereafter adopted by the SEC. Upon the request of the Stockholders, the Company will deliver to the Stockholders a written statement as to whether it has complied with such information and requirements. 

 

	 	12.	Transfer of Registration Rights. 

 (a) Each Stockholder may in its sole discretion
transfer all or any portion of its then-remaining registration rights under Sections 2 through 11 of this Agreement to (i) any Affiliate of such Stockholder or (ii) any transferee who would satisfy the definition of a “Demand
Stockholder” as a result of the acquisition of Warrants or Warrant Shares (other than, in the case of the Warrant Shares, pursuant to an effective Registration Statement) (each, a “Permitted Transferee”). Any transfer of registration
rights pursuant to this Section 12(a) shall be effective upon receipt by the Company of (x) written notice from the Stockholder stating the name and address of any Permitted Transferee and identifying the amount of Registrable Securities
with respect to which the rights under this Agreement are being transferred and the nature of the rights so transferred and (y) a joinder, in the form attached as Exhibit B hereto (the “Joinder”), providing that the Permitted
Transferee shall be bound by and shall fully comply with the terms of this Agreement (including the provisions of this Section 12) or another written agreement from the transferee to be bound by the terms of this Agreement. In connection with
any such transfer, the term “Stockholders” as used in this Agreement shall, where appropriate to assign such rights to such Permitted Transferee, be deemed to include the Permitted Transferee holder of such Registrable Securities. The
Stockholders and such Permitted Transferees may exercise the registration rights hereunder in such proportion (not to exceed the then-remaining registration rights hereunder) as they shall agree among themselves. 

(b) After such transfer, the transferring Stockholder shall retain its rights under this Agreement with respect to all other Registrable
Securities owned by such Stockholder. Upon request of the transferring Stockholder, the Company shall execute a Joinder or another investor rights agreement with such Permitted Transferee or a proposed transferee substantially similar to the
applicable sections of this Agreement. 
  

	 	13.	Conversion of Other Securities. 

 If a Stockholder offers Registrable Securities by
forward sale, or any options, rights, warrants or other securities issued by it or any other person that are offered with, convertible into or exercisable or exchangeable for any Registrable Securities, the Registrable Securities subject to such
forward sale or underlying such options, rights, warrants or other securities shall be eligible for registration pursuant to Sections 2, 3 and 4 of this Agreement. 

  
 19 

	 	14.	Board of Directors. 

 (a) Composition. Prior to the execution of this Agreement,
the Company has taken all actions (including by amendment of the Amended and Restated Bylaws of the Company (the “By-laws”), if required) necessary to increase the number of directors that shall constitute the entire board to nine
(9) and, effective as of the date hereof, has appointed to the Board of the Company each of William Pruellage and Peter Aquino as a director to serve until his successor is elected and qualified or his resignation or removal in accordance with
the By-laws. For so long as the Initial Stockholder maintains the right to designate one or more directors pursuant to Section 14(b), the Company shall not support any increase in the number of directors of more than ten (10) total
directors without the Initial Stockholder’s prior written consent. 
 (b) Designation of Directors. Until the date on which all
Warrants have been sold or otherwise transferred by the Initial Stockholder (other than to an Affiliate) or the underlying Common Stock has been sold or transferred (other than to an Affiliate), the Initial Stockholder (or an Affiliate of the
Initial Stockholder in the event the Initial Stockholder sells or otherwise transfers all or a part of the Warrants or the underlying Common Stock to an Affiliate) shall have the right to designate to the Board two (2) directors, the identity
of such director designees to be at the discretion of the Initial Stockholder so long as any such director designees are not restricted from serving on the board of directors of a U.S. public company and shall satisfy the corporate governance
guidelines of the Company and NASDAQ; provided, however, that following any (x) transfer by any Affiliate of the Initial Stockholder and/or the Initial Stockholder, as applicable, of the Notes or (y) any repayment of the
Notes (i) if the Initial Stockholder, collectively with any of its Affiliates (including the initial holder thereof) retains the Notes representing between 65% and 35% of the Original Principal Amount (calculated by reference to the then
principal amount of the Notes plus accrued and unpaid interest held by any such Affiliate of the Initial Stockholder and/or the Initial Stockholder, as applicable), the Initial Stockholder shall be entitled to designate to the Board one
(1) director (for the avoidance of doubt, if the amounts so retained exceed 65%, the Initial Stockholder shall retain the right to designate to the Board two (2) directors) and (ii) if the Initial Stockholder retains the Notes
representing less than 35% of the Original Principal Amount (calculated by reference to the then principal amount of the Notes plus accrued and unpaid interest held by any such Affiliate of the Initial Stockholder and/or the Initial Stockholder, as
applicable), then the Initial Stockholder’s designation right will terminate. The Initial Stockholder’s right to designate directors shall not be transferrable (other than to any commonly controlled Affiliates) without the prior written
consent of the Company. 
 (c) Election of Directors. The Company shall nominate and take all action within its power to cause all
nominees designated pursuant to Section 14(b) to be included in the slate of nominees recommended by the Board to the Company’s stockholders for election as directors at each annual or special meeting of the stockholders of the Company at
which directors are to be elected to the Board (and/or in connection with any election 

  
 20 

 
by written consent) and the Company shall use all reasonable best efforts to cause the election of each such nominee, including recommending and soliciting proxies in favor of the election of
such nominees. 
 (d) Replacement of Directors. In the event that a vacancy is created at any time by the death, disability,
retirement, resignation or removal (with or without cause) of a director nominated pursuant to Section 14(b) or designated pursuant to this Section 14(d), or in the event of the failure of any such nominee to be elected, the Initial
Stockholder shall have the right to designate a replacement to fill such vacancy, provided that any such nominee shall not be restricted from serving on the board of directors of a U.S. public company and shall satisfy the corporate governance
guidelines of the Company and NASDAQ. The Company shall take all action within its power to cause such vacancy to be filled by the replacement so designated, and the Board shall promptly elect such designee to the Board. Upon the written request of
the Initial Stockholder, the Company shall take all action within its power to submit to a vote of stockholders of the Company, and use reasonable best efforts to cause (including through the solicitation of proxies), the removal, with or without
cause, any Director previously nominated pursuant to Section 8(b) or designated pursuant to this Section 14(d), and to elect any replacement director designated by the Initial Stockholder as provided in the first sentence of this
Section 14(d). 
 (e) Committees. The Company shall take all action within its power to cause any committee of the Board to
include in its membership at least one of the Initial Stockholder’s designated directors, except to the extent that such membership would violate applicable securities laws or stock exchange or stock market rules. 

(f) No Limitation. The provisions of this Section 14 are intended to provide the Initial Stockholder with the minimum Board
representation rights set forth herein. Nothing in this Agreement shall prevent the Company from having a greater number of Initial Stockholder nominees or designees on the Board than otherwise provided herein. 

(g) Indemnification, Expense Reimbursement and Insurance. Any director designated or nominated by the Initial Stockholder that serves
on the Board shall be entitled to all benefits and rights under any indemnification, exculpation and reimbursement agreement, policy and provision of any organizational document (including as to advancement or reimbursement of expenses), as well as
any director and officer insurance policy maintained by the Company, in each case to the fullest extent made available to any other director of the Board. Without limiting the foregoing, (i) the benefits and rights referenced in the previous
sentence shall not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of any director designated or nominated by the Initial Stockholder without the Initial Stockholder’s prior written
consent and (ii) the Company shall at all times maintain in full force and effect a policy or policies of director and officer liability insurance, issued by insurers of recognized 

  
 21 

 
responsibility, insuring against such losses and risks, and in such amounts, as are at least as favorable as are maintained by the Company as of the date hereof. Notwithstanding anything to the
contrary in the Company’s certificate of incorporation or By-laws or in this clause (g), and without limiting any of the rights set forth therein, the Company shall indemnify and hold harmless any director designated or nominated by the Initial
Stockholder that serves on the Board to the fullest extent permitted by applicable law with respect to any losses arising from or related to the fact that such director is or was a director of the Company, or is or was serving at the request of the
Company as a director, officer, employee, or agent of the Company or another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, or by reason of anything done or not
done by such director in any such capacity. The Company hereby agrees to enter into a customary indemnification agreement with the director designated or nominated by the Initial Stockholder as soon as reasonably practicable after the date hereof.

 (h) No Impairment. The Company shall not take any action to cause the amendment of its certificate of incorporation and by-laws
such that the Initial Stockholder’s rights under this Section 14 would not be given effect; provided, that, for the avoidance of doubt, the foregoing shall not prohibit any increase or decrease in the size of the Board subject to the
rights of the Initial Stockholder upon any increase set forth in clause (a) above. 
 (i) Standstill. The Initial Stockholder
(or any Affiliate of the Initial Stockholder in the event the Initial Stockholder sells or otherwise transfers all or a part of the Warrants or the Warrant Shares to an Affiliate) agrees that, for the period beginning on the date of this Agreement
and ending on the earliest to occur of (x) the occurrence of a Significant Event, (y) such date that the Initial Stockholder (or any Affiliate thereof) no longer has the right to designate at least one director pursuant to the terms
of Section 14(b) of this Agreement and (z) the date following the annual meeting of the stockholders of the Company at which the Initial Stockholder has declined to nominate a designee to the Board at such meeting and the Initial
Stockholder has delivered written notice to the Company that is has irrevocably waived and relinquished its right to nominate any designees to the Board pursuant to the provisions of Section 14(b) of this Agreement in the future, unless
otherwise agreed or consented to by the Board, neither the Initial Stockholder nor any of its Affiliates or representatives acting at the direction and on behalf of the Initial Stockholder will (the “Standstill Period”),
(a) effect or affirmatively seek, publicly offer or publicly propose to effect or cause, or knowingly and actively assist any third party to effect, offer or publicly propose to effect (i) any acquisition of any voting equity securities of
the Company other than (x) the acquisition by the Initial Stockholder (or any of its Affiliates) of beneficial ownership of (A) any of the Warrant Shares or securities issued by the Company in respect of (whether by dividend or otherwise)
any warrant shares, (B) additional voting equity securities of the Company not to exceed, in the aggregate, 1% of the issued and outstanding shares of the Company’s outstanding voting securities at the time of measurement and
(3) any voting equity securities issued by the 

  
 22 

 
Company to the Initial Stockholder’s nominees to the Board (which shall not be included in the calculation of the 1% in clause (B) above); (ii) any tender or exchange offer,
merger, consolidation involving the acquisition of the Company other than any such transaction made or agreed to or recommended by the Company; (iii) any recapitalization, restructuring, liquidation, dissolution with respect to the Company or
any material portion of the Company’s business (other than as may be proposed by the Company) or (iv) any knowing “solicitation” of “proxies” (as such terms are used in the proxy rules of the Securities and Exchange
Commission ) or consents to vote any voting securities of the Company with respect to any matter not proposed or recommended (other than with respect to its nominees to the Board and other than with respect to any matter that has been recommended by
the Company or its Board); (b) form or knowingly and intentionally join a “group” (as defined under the 1934 Act) with respect to the voting equity securities of the Company (other than any “group” formed solely among the
Initial Stockholder and its Affiliates). For purposes of this section “Affiliates” shall not include any of the Initial Stockholder’s designees or nominees to the Board. Nothing shall restrict such directors from exercising
their respective fiduciary duties as members of the Board. Nothing shall restrict or prohibit the Initial Stockholder from (x) engaging or seeking to engage in discussions (or, with the consent of the Company, negotiations) with the
Company regarding any of the transactions or actions of the type prohibited or restricted by the foregoing so long as the Initial Stockholder seeks to do so on a direct and consensual basis (and the Company may, from time to time, as determined in
its sole discretion, grant any waiver of the restrictions or prohibitions set forth in this Section 14(i)(a) and no such waiver shall require a written amendment to this Agreement)). Nothing in this Agreement shall prohibit or limit the
Initial Stockholder or any of its Affiliates from making any public disclosure or filing that such person reasonably determines in good faith, after consultation with counsel, is required pursuant to the 1934 Act or the rules and regulations
promulgated thereunder or any form or schedule filed pursuant thereto (provided that, the foregoing shall not include Schedule TO to the extent the prohibitions and restrictions set forth in clause (a)(ii) of the first sentence of this
Section 14(i) remain in effect). 
 (j) Notwithstanding anything to the contrary in this Agreement, but without limiting the effect of
any waiver that may be granted by the Company pursuant to the application of Section 14(i) above, the terms and conditions of this Section 14 may only be amended or modified with the prior written consent of both the Company and the
Initial Stockholder.

such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any
such suit, action or proceeding in any such court or that any such suit, action or proceeding which is brought in any such court has been brought in an inconvenient 

  
 25 

 
forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the
foregoing, each party agrees that service of process on such party as provided in Section 15(a) shall be deemed effective service of process on such party.

(h) Entire Agreement. This Agreement contains the entire agreement between the parties hereto with respect to the subject matter hereof
and supersedes and replaces all other prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof.

Agreement, or the negotiation, execution or performance of this Agreement may only be made against the entities that are expressly identified as parties hereto (or their successors and permitted assigns, or any third party beneficiaries hereto) and
none of (a) the Stockholders or any of their respective Affiliates’ (other than the Stockholders), members, managers, directors, officers, employees, agents, representatives or assignees of any of the foregoing (collectively, the
“Stockholder Related Parties”) or (b) the Company’s or any of its Affiliates’ stockholders (other than the Company), members, managers, directors, officers, employees, agents, representatives or assignees of any of the
foregoing (collectively, the “Company Related Parties”), in each case, shall have any liability for any obligations or liabilities of the other parties to this Agreement or for any action (whether in tort, contract or otherwise) based on,
in respect of, or by reason of, the transactions contemplated hereby or in respect of any oral representations made or alleged to be made in connection herewith. Without limiting the rights of the parties hereunder against the other parties to this
Agreement, in no event shall (i) the Company or any of its Affiliates, and the Company agrees not to and to cause its Affiliates not to, seek to enforce this Agreement against, commence any actions for breach of this Agreement against, or seek
to recover monetary damages from, any Stockholder Related Party, or (ii) the Stockholder or any of its Affiliates, and the Stockholder agrees not to and to cause its Affiliates not to, seek to enforce this Agreement against, commence any

 (j) Captions. The headings and other captions in this Agreement are for convenience and
reference only and shall not be used in interpreting, construing or enforcing any provision of this Agreement. 
 (k) Severability.
If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this
Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any
party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to affect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby
be consummated as originally contemplated to the fullest extent possible. 
 (l) Amendments. Except as otherwise provided in
Section 14(j), the provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given, without the written
consent of (i) the Company and (ii) the Stockholders collectively then holding Warrants and Warrant Shares representing more than 50% of the total number of Warrant Shares then held by the Stockholders (calculated as the sum of all issued
and outstanding Warrant Shares plus all Warrant Shares issuable upon exercise of all outstanding Warrants); provided that so long as the Initial Stockholder continues to hold Warrants and Warrant Shares representing at least 10% of the total
number of Warrant Shares then held by the Stockholders (calculated as the sum of all issued and outstanding Warrant Shares plus all Warrant Shares issuable upon exercise of all outstanding Warrants), in the aggregate, any such amendment shall also
require the prior written consent of the Initial Stockholder. 
 (m) Aggregation of Stock. All Registrable Securities held by or
acquired by any Affiliated Persons will be aggregated together for the purpose of determining the availability of any rights under this Agreement. 

(n) Equitable Relief. The parties hereto, in addition to being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this Agreement. Accordingly, each party acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the other parties, by vitiating the intent and
purpose of the transaction contemplated hereby. Accordingly, each party acknowledges that the remedy at law for a breach of its obligations under this Agreement will be inadequate and agrees, in the event of a breach or threatened breach by such
party of the provisions of this Agreement, that the other parties hereto

 Exhibit A 

Plan of Distribution 
 Each
selling stockholder may sell the securities being offered hereby in one or more of the following ways from time to time: 
  

	 	•	 	to underwriters or dealers for resale to the public or to institutional investors; 

  

	 	•	 	directly to institutional investors; 

  

	 	•	 	directly to a limited number of purchasers or to a single purchaser; 

  

	 	•	 	through agents to the public or to institutional investors; or 

  

	 	•	 	through a combination of any of these methods of sale. 

 The prospectus supplement with respect
to each series of securities will state the terms of the offering of the securities, including: 
  

	 	•	 	the offering terms, including the name or names of any underwriters, dealers or agents; 

  

	 	•	 	the purchase price of the securities and the net proceeds to be received by the selling stockholder from the sale; 

  

	 	•	 	any underwriting discounts or agency fees and other items constituting underwriters’ or agents’ compensation; 

  

	 	•	 	any public offering price; 

  

	 	•	 	any discounts or concessions allowed or reallowed or paid to dealers; and 

  

	 	•	 	any securities exchange on which the securities may be listed. 

 If the selling stockholders
use underwriters or dealers in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including: 

 

	 	•	 	privately negotiated transactions; 

  

	 	•	 	at a fixed public offering price or prices, which may be changed; 

  

	 	•	 	in “at the market offerings” within the meaning of Rule 415(a)(4) of the Securities Act; 

  

	 	•	 	at prices related to prevailing market prices; or 

  

	 	•	 	at negotiated prices. 

 Any initial public offering price and any discounts or concessions allowed or reallowed or paid
to dealers may be changed from time to time. 
 If underwriters are used in the sale of any securities, the securities may be offered either
to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to certain conditions precedent. The
underwriters will be obligated to purchase all of the securities if they purchase any of the securities. 
 We may enter into derivative
transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may
sell securities covered by this prospectus and the applicable prospectus supplement, including short sale transactions. If so, the third party may use securities pledged by the selling stockholder or borrowed from the selling stockholder or others
to settle those sales or to close out any related open borrowings of common shares, and may use securities received from the selling stockholder in settlement of those derivatives to close out any related open borrowings of common shares. The third
party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement or a post-effective amendment to this registration statement. 

If indicated in an applicable prospectus supplement, the selling stockholder may sell the securities through agents from time to time. The
applicable prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions the selling stockholder pay to them. Generally, any agent will be acting on a best efforts basis for the period of its
appointment. The selling stockholder may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from the selling stockholder at the public offering price set forth in the applicable prospectus
supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The delayed delivery contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and
the applicable prospectus supplement will set forth any commissions the selling stockholder pay for solicitation of these delayed delivery contracts. 

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing
upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for the selling stockholder. Any remarketing firm
will be identified and the terms of its agreements, if any, with the selling stockholder and its compensation will be described in the applicable prospectus supplement. 

Agents, underwriters and other third parties described above may be entitled to indemnification by the Company and the selling stockholder
against certain civil liabilities under the Securities Act, or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents, underwriters and such other third parties may be customers
of, engage in transactions with, or perform services for the Company or the selling stockholder in the ordinary course of business. 

  
 2 

 Each series of securities will be a new issue of securities and will have no established trading
market, other than our common stock, which is listed on NASDAQ. Any common stock sold will be listed on NASDAQ. The securities other than the common stock may or may not be listed on a national securities exchange. Any underwriters to whom
securities are sold by the selling stockholder for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.
