(b) any additional shares of Common Stock of the Company so that after the full and complete Exercise of the Warrant (including the aggregate number of shares of Common Stock previously issued from time to time as a result of any partial
exercise of this Warrant), the Holder, together with all Affiliates of the Holder and all Persons to which the Holder or its Affiliates have transferred any shares of Common Stock or Series B Preferred Stock acquired under the Stock Purchase
Agreement, hold an aggregate number of shares of Common Stock (assuming the conversion of Series B Preferred Stock into Common Stock as of such time of such Exercise) equal to 51% of the Common Stock Deemed Outstanding on the date of final exercise
of this Warrant in full, subject to adjustment as provided herein and pursuant to the provisions set forth in Section 5(e) (such shares of Common Stock or Series B Preferred Stock, together with the stock and other securities and property at the
time receivable upon the exercise of this Warrant, the “Warrant Shares”), at a price per share of Common Stock equal to the Exercise Price as defined in Section 3 below, at any time during the Accelerated Term or Term (as defined
below). 
 Holder agrees with the Company that this Warrant to Purchase Shares of the Company (this “Warrant” or this “Agreement”) is
issued, and all rights hereunder shall be held, subject to all of the conditions, limitations and provisions set forth herein. 
  

	1.	Date of Issuance; Term.  

 (a)    Date of Issuance. This
Warrant shall be deemed to be issued on the Closing Date (as defined in the Share Purchase Agreement) (“Date of Issuance”). 

(b)    Term. The term of this Warrant begins on the date that is the eighteen (18) month anniversary of the Date of
Issuance and ends at 5:00 p.m., New York City time, on the date that is the twenty-one (21) month anniversary of the Date of Issuance (such period, as may be modified pursuant to the terms hereof, the
“Term”). This Warrant was issued in conjunction with that certain Share Purchase Agreement by and between the Company and Weichai America Corp. (the “Investor”) dated March 20, 2017 (the “Share Purchase
Agreement”), that certain Investor Rights Agreement (the “Investor Rights Agreement”) by and 

 
between the Company and the Investor dated as of the Date of Issuance, and that certain Shareholders Agreement (the “Shareholders Agreement”) by and between the Investor and other
parties thereto, dated March 20, 2017, entered into in conjunction herewith. 
 (c)    Acceleration. Notwithstanding
the foregoing, to the extent that, prior to the beginning of the Term set forth in Section 1(b) herein, (i) the Company is in default under the TPG Credit Agreement (as defined under Share Purchase Agreement) or any refinancings or replacements
thereof, or (ii) any other credit agreement, bond, note, mortgage, indenture or other debt financing or refinancing arrangement with an outstanding obligation of $5,000,000 or more, (ii) as a result of such default, the lender under such
debt financing arrangement has accelerated all outstanding obligations of the Company under such debt financing arrangement by written notice to the Company thereof (the amount of such accelerated obligation, the “Accelerated Obligation”),
and (iii) the Company does not cure such default within any cure period set out in such notice of default or within 10 days in case there is no cure period set out in such notice of default, if any (the “Cure Period”), the Warrant
shall become exercisable for a number of shares of Common Stock equal to the ratio of (x) the amount of the Accelerated Obligation, divided by (y) the Exercise Price for the Warrant, and the portion of the Warrant that is so exercisable
shall continue to be exercisable for a period of ten (10) days following the expiration of the Cure Period (each such period, an “Accelerated Term”). To the extent such exercisable portion of the Warrant is not fully exercised during
such Accelerated Term, the Warrant (including such portion) shall continue to be exercisable pursuant to the terms hereof. Notwithstanding the foregoing, if the Company has cured such default on or prior to the date of Exercise of the Warrant
pursuant to this Section 1(c) or the Holder fails to exercise the Warrant within the Accelerated Term, the Warrant shall no longer be accelerated pursuant to this Section 1(c) but still be exercisable pursuant to Section 1(b).

	2.	Exercise.  

 (a)    Manner of Exercise. During the
Accelerated Term or the Term (as the case may be), this Warrant may be Exercised as to all or any lesser number of whole Warrant Shares for which this Warrant is then exercisable upon surrender of this Warrant, with the Exercise Form attached hereto
as Exhibit A (the “Exercise Form”) duly completed and executed, together with the full Exercise Price (as defined below) for each Warrant Share as to which this Warrant is Exercised, at the office of the Company,
Attention: General Counsel – William Buzogany; Phone: 773-425-2323, or at such other office or agency as the Company may designate in writing, by overnight mail,
with an advance copy of the Exercise Form sent to the Company and its transfer agent (“Transfer Agent”) by facsimile (such surrender and payment of the Exercise Price hereinafter called the “Exercise” of this Warrant). If Holder
intends to Exercise the Warrant and provides a written notice indicating the number of Warrant Shares to be Exercised and the approximate Date of Exercise at any time at least one (1) month prior to the start of the Term, the Company shall take
all necessary actions in a timely manner to obtain consents or approvals from any and all third parties and government authorities that failure of which would constitute a Material Adverse Effect (as defined in the Share Purchase Agreement)
(“Material Third Party Consents”) prior to the Date of Exercise. If the Company fails to obtain all requisite Material Third Party Consents before seven days prior to the expiration of the Term or the extension thereof, the Term of this
Warrant shall be extended until the Company has obtained such Material Third Party Consents. For the avoidance of doubt, no failure by the Company to obtain any Material Third Party Consents shall preclude or in any way limit the ability of Holder
to Exercise this Warrant. 
 (b)    Date of Exercise. The “Date of Exercise” of the Warrant shall be defined as
the Trading Day that the Exercise Form attached hereto as Exhibit A, completed and executed, is sent by facsimile to, and received during regular business hours by, the Company, provided that (i) the original Warrant
and Exercise Form are received by the Company within two (2) Trading Days following such date, and (ii) the Exercise Price is satisfied within thirty (30) days (provided that the Warrant Shares shall not be deemed to

 
be issued to the Holder until the Exercise Price is actually received by the Company). Upon the Date of Exercise, the Warrant shall be deemed to have been exercised, and upon the receipt of the
Exercise Price in accordance with the preceding sentence, Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been Exercised, irrespective of the date
such Warrant Shares are credited to the Holder’s Depository Trust Company (“DTC”) account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. 

(c)    Delivery of Warrant Shares Upon Exercise. Within three (3) Trading Days after any Date of Exercise (or if the
Holder requests the issuance of physical certificate(s) rather than through DTC credit, within two (2) Trading Days after receipt by the Company of the original Warrant) (the “Delivery Period”), the Company shall issue and deliver (or
cause its Transfer Agent to issue and deliver) in accordance with the terms hereof to or upon the order of the Holder that number of Exercise Shares for the portion of this Warrant Exercised, as shall be determined in accordance herewith. Upon the
Exercise of this Warrant or any part hereof, the Company shall, at its own cost and expense, take all commercially reasonable actions, including obtaining and delivering an opinion of counsel, to assure that the Transfer Agent shall issue stock
certificates in the name of Holder (or its nominee) or such other persons as designated by Holder and in such denominations, representing the number of Warrant Shares issuable upon such Exercise (“Exercise Shares”). Notwithstanding the
foregoing, the Company shall not be required to pay any tax or other charge imposed in connection with any transfer involved in the issuance of any certificate for Exercise Shares in any name other than that of the original registered holder of this
Warrant.  
 (d)    Delivery Failure. In addition to any other remedies which may be available to the Holder, in
the event that the Company fails for any reason to effect delivery of the Exercise Shares by the end of the Delivery Period (a “Delivery Failure”), the Holder will be entitled to revoke all or part of the relevant Exercise Form by delivery
of a notice to such effect to the Company not later than three (3) Trading Days after the end of the Delivery Period, whereupon the Company and the Holder shall each be restored to their respective positions immediately prior to the delivery of
such notice, including without limitation the return of the Warrant to the Holder and the return of certificates representing Exercise Shares to the Company. 

(e)    Legends. 

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

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
SECURITIES LAWS. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM
REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION, PURSUANT TO RULES 144 OR 144A UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER 

 
APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION OR GUIDANCE, SUCH AS A SO-CALLED “4(1) AND A HALF” SALE”, SUBJECT TO DELIVERY OF AN
OPINION, AS PROVIDED IN THE WARRANT, DATED AS OF                 , 20    , ISSUED BY THE COMPANY.” 

“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN
INVESTOR RIGHTS AGREEMENT DATED AS OF             , 2017, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY BE
OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.” 

(ii)    Removal of Restrictive Legends. The certificates evidencing the Exercise Shares shall not contain any legend restricting
the transfer thereof (including the legend set forth above in subsection 2(e)(i)): (A) while a registration statement (including a Registration Statement, as defined in the Investor Rights Agreement) covering the resale of such security is
effective under the Securities Act, or (B) following any sale of such Exercise Shares pursuant to Rule 144, or (C) if such Exercise Shares are eligible for sale under Rule 144(b)(1), or (D) if such legend is not required under
applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). If the Unrestricted Conditions are satisfied, the Company
shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Unrestricted Conditions are satisfied, if required and to the extent permitted by the Transfer Agent, to effect the issuance of the Exercise Shares without a
restrictive legend or removal of the legend hereunder. The Company agrees that, following the Effective Date, at such time as the Unrestricted Conditions are met or such legend is otherwise no longer required under this Section 2(e), it will, no
later than five (5) Trading Days following the delivery (the “Unlegended Shares Delivery Deadline”) by the Holder to the Company of a certificate representing Exercise Shares containing a restrictive legend (such fifth Trading Day,
the “Legend Removal Date”), deliver or cause to be delivered to such Holder a certificate (or electronic transfer) representing such shares that is free from all restrictive and other legends. For purposes hereof, “Effective
Date” shall mean the date that the Registration Statement that the Company is required to file pursuant to the Investor Rights Agreement has been declared effective by the SEC. 

(iii)    Sale of Unlegended Shares. Holder agrees that the removal of the restrictive legend from any certificates representing
securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that the Holder will sell, transfer, assign, pledge, hypothecate or otherwise dispose of this Warrant or any Exercise Shares pursuant to either the
registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a Registration Statement, they will be sold in compliance with
the plan of distribution set forth therein. 
 (f)    Cancellation of Warrant. This Warrant shall be canceled upon the
earliest to occur of the following: (i) expiration at the end of the Term; (ii) the full Exercise of this Warrant; or (iii) the consummation of a Major Transaction. If this Warrant is partially (and not fully) Exercised, Holder shall
be entitled to receive a new Warrant (containing terms identical to this Warrant) representing any unexercised and unexpired portion of this Warrant. In the event of a Major Transaction (as defined below), any portion of this Warrant that is not
Exercised pursuant to the terms of this Warrant prior to the closing of such Major Transaction shall be cancelled and terminated without further action by the Holder or the Company upon consummation of such Major Transaction. 

 (g)     Delivery of Electronic Shares. In lieu of delivering physical
certificates representing the Exercise Shares or shares of Common Stock submitted for legend removal, provided the Transfer Agent is participating in the DTC Fast Automated Securities Transfer (“FAST”) program, upon written request of the
Holder, the Company shall use commercially reasonable efforts to cause its Transfer Agent to electronically transmit such securities by crediting the account of the Holder’s prime broker with DTC through its Deposit Withdrawal Agent Commission
(DWAC) system. The time periods for delivery and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates.

 (h)    Buy-In. In addition to any other rights available to the Holder, if the
Company fails to cause its Transfer Agent to transmit to the Holder a certificate or certificates, or electronic shares through DWAC, representing Exercise Shares on or before the end of the applicable Delivery Period (other than a failure caused by
incorrect or incomplete information provided by Holder to the Company hereunder), and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise
purchases shares of Warrant Shares to deliver in satisfaction of a sale by the Holder of the Exercise Shares that the Company was required to deliver to the Holder in connection with such Exercise (a
“Buy-In”), then the Company shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of
Warrant Shares so purchased exceeds (y) the amount (the “Sales Price”) obtained by multiplying (A) the number of Exercise Shares that the Company was required to deliver to the Holder in connection with the Exercise at issue
times (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such
Exercise was not timely honored or deliver to the Holder the Exercise Shares that would have been issued had the Company timely complied with its Exercise and delivery obligations hereunder. For example, if the Holder purchases Warrant Shares having
a total purchase price of $11,000 to cover a Buy-In with respect to an attempted Exercise to cover the sale of Warrant Shares with an aggregate Sales Price of $10,000, under clause (1) of the immediately
preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice, within three (3) Trading Days after the occurrence of a Buy-In, indicating
the amounts payable to the Holder in respect of such Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit a Holder’s right to
pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing
Exercise Shares upon Exercise of the Warrant as required pursuant to the terms hereof; provided, however, that the Holder shall not be entitled to both (i) reinstate the portion of the Warrant and equivalent number of Exercise Shares for which
such Exercise was not timely honored and (ii) receive such Exercise Shares. 
  

	3.	Payment of Warrant Exercise Price.  

 (a)    Exercise
Price. Subject to adjustment pursuant to terms of Section 3(b) and 5(f) herein, the exercise price per exercised Warrant Share (“Exercise Price”) shall be equal to the average Volume Weighted Average Price of one (1) share of the
Company’s Common Stock during the twenty (20) 

 
consecutive Trading Day period immediately preceding the Date of Exercise multiplied by 85%; provided that in the case that Delisting Condition exists, the Exercise Price shall be equal to
the following: (x) the average Volume Weighted Average Price of one (1) share of the Company’s Common Stock during the twenty (20) consecutive Trading Day (or if the Common Stock is not then listed or quoted on NASDAQ) Business
Day (as applicable) period immediately preceding the Date of Exercise multiplied by 50%; or (y) if no Volume Weighted Average Price is available for the twenty (20) consecutive Trading Day period immediately preceding the Date of
Exercise, the Volume Weighted Average Price for twenty (20) Trading Days which are most recently available preceding the Date of Exercise multiplied by 50%. 

Payment of the Exercise Price shall be made in cash, cashier’s check or wire transfer. 

(b)    Adjustment to the Exercise Price. 

(A) Subject to the limitation set forth in Section 3(b)(C) below, in the event that the Company’s 2017 EBITDA is less than $22 million, the aggregate
Exercise Price for the Warrant Shares shall be adjusted by deducting an amount derived from the following formula (“EBITDA Adjustment Amount”): 

EBITDA Adjustment Amount = $27.5 million – (2017 EBITDA × 1.25) 

(B)    Subject to the limitation set forth in Section 3(b)(C) below, to the extent that the net book value per share of Common Stock as of
December 31, 2016 (based on the audited consolidated balance sheet of the Company and its subsidiaries as of December 31, 2016) (“Actual 2016 Net Book Value Per Share“) is less than $8.00, then the aggregate Exercise Price for
the Warrant Shares shall be further adjusted by deducting an amount derived from the following formula (“Net Book Value Adjustment Amount”): 

Net Book Value Adjustment Amount = ($8.00 - Actual 2016 Net Book Value Per Share) × 7,500,000 

provided that, if the Actual 2016 Net Book Value Per Share is equal to or greater than $8.00, there will be no adjustment. 

(C)    Notwithstanding the foregoing, the aggregate amount of the EBITDA Adjustment Amount and the Net Book Value Adjustment Amount
(collectively, “Aggregate Adjustment Amount”) shall not exceed $15 million. If the aggregate Exercise Price for the Warrant Shares is less than the Aggregate Adjustment Amount, then following the full Exercise of the Warrant the
Company shall be liable to pay the shortfall between the aggregate Exercise Price for the Warrant Shares and the Aggregate Adjustment Amount to the Holder. In the event that either the 2017 EBITDA or Actual 2016 Net Book Value Per Share is zero or a
negative number, then 2017 EBITDA or Actual 2016 Net Book Value Per Share, as the case may be, shall be deemed to be 0.01 for the purposes of calculation of the adjustments. 

(c)    Payment of Additional Amounts for Warrant Shares. In the event that the Holder exercises all or any part of the
Warrant during the Accelerated Term for the Exercise Price pursuant to Section 3(a)(x) or (y) and (i) there exists a Delisting Condition at the time of exercise of the Warrant; but (ii) the Company Common Stock is listed on Nasdaq as of
the date that is the eighteen (18) month anniversary of the Closing, the Holder shall pay to the Company by wire transfer of immediately available funds to an account designated in writing by the Company, promptly following the date that is the
eighteen (18) month anniversary of the Closing, an additional amount equal to the quotient of (a) the aggregate Exercise Price paid in respect of all of the Warrant Shares exercised by the Holder during the Accelerated Term, multiplied
by (b) 0.7. In the event that (i) there is no Delisting Condition when the Holder exercises the Warrant during the Accelerated Term; and (ii) the Company Common Stock is not listed on Nasdaq as of the date that is the eighteen
(18) month anniversary of the Closing, the Company shall pay to the Holder by wire transfer of immediately available funds to an account designated in writing by the Holder, promptly following the date that is the eighteen (18) month
anniversary of the Closing, an additional amount equal to the quotient of (a) the aggregate Exercise Price paid in respect of all of the Warrant Shares exercised by the Holder during the Accelerated Term, multiplied by (b) 35/85. 

 (d)    Dispute Resolution. In the case of a dispute as to the determination of
the closing price or the Volume Weighted Average Price of the Company’s Common Stock or the arithmetic calculation of the Exercise Price or Market Price, the Company shall submit the disputed determinations or arithmetic calculations via
facsimile within four (4) Business Days of receipt, or deemed receipt, of the Exercise Notice, or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such
determination or calculation within two (2) Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business Days submit via facsimile (i) the
disputed determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock to an independent, reputable investment bank selected by the Company and approved by the Holder, which approval shall not be
unreasonably withheld or delayed or (ii) the disputed arithmetic calculation of the Exercise Price or Market Price to the Company’s independent, outside accountant, or another accounting firm of national standing selected by the Company.
The Company shall cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than the later of (i) five (5) Business Days
from the time it receives the disputed determinations or calculations or (ii) five (5) Business Days from the selection of the investment bank and accounting firm, as applicable. Such investment bank’s or accountant’s
determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error. 
  

	4.	Transfer and Registration. 

 (a)    Transfer Rights. Subject to the provisions
of Section 8 of this Warrant, this Warrant may be transferred on the books of the Company, in whole or in part, in person or by attorney, upon surrender of this Warrant properly completed and endorsed. This Warrant shall be canceled upon such
surrender and, as soon as practicable thereafter, the person to whom such transfer is made shall be entitled to receive a new Warrant or Warrants as to the portion of this Warrant transferred, and Holder shall be entitled to receive a new Warrant as
to any portion hereof retained. 
 (b)    Registrable Securities. Subject to the terms of the Investor Rights Agreement, the Warrant
Shares issuable upon the Exercise of this Warrant may be registered under the Securities Act as contemplated by the Investor Rights Agreement. 
  

	5.	Adjustments. 

 (a)    Participation. The Holder, as the holder of this
Warrant, shall be entitled to receive such dividends paid and distributions of any kind made to the holders of equity securities of the Company to the same extent as if the Holder had Exercised this Warrant (without regard to any limitations on
exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized and reserved to effect any such exercise and issuance) and had held such shares of equity securities on the record date for such dividends
and distributions. Payments under the preceding sentence shall be made concurrently with the dividend or distribution to the holders of equity securities. 

(b)    Recapitalization or Reclassification; Consolidation, Merger or Sale. If the Company shall at any time effect a stock
split, payment of stock dividend, recapitalization, reclassification or other similar transaction of such character that the shares of equity securities shall be changed into or become 

 
exchangeable for a larger or smaller number of shares, then upon the effective date thereof, the number of shares of Warrant Shares which Holder shall be entitled to purchase upon Exercise of
this Warrant shall be increased or decreased, as the case may be, in direct proportion to the increase or decrease in the number of shares of equity securities by reason of such stock split, payment of stock dividend, recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the case of an increase in the number of shares, proportionally decreased and, in the case of decrease in the number of shares, proportionally increased. In addition, if
any recapitalization, reclassification or reorganization of the share capital of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its shares and/or assets or other
transaction (including, without limitation, a sale of substantially all of its assets followed by a liquidation) shall be effected in such a way that holders of shares of equity securities shall be entitled to receive shares, securities or other
assets or property (a “Change”), then, lawful and adequate provisions shall be made by the Company whereby the Holder shall thereafter have the right to purchase and receive (in lieu of the shares of Warrant Shares immediately theretofore
purchasable and receivable upon the exercise of the rights represented hereby) such shares, securities or other assets or property as may be issued or payable with respect to or in exchange for the number of outstanding shares of equity securities
which such Holder would have been entitled to receive had such Holder exercised this Warrant immediately prior to the consummation of such Change. The provisions of this Section 5(b) shall similarly apply to successive Changes. The Company shall
give Holder the same notice it provides to holders of equity securities of any transaction or Change described in this Section 5(b). 

(c)    Rights Upon Major Transaction. 

(i)    Major Transaction. In the event that a Major Transaction (as defined below) is consummated prior to the beginning of the
Term, the Warrant shall expire and shall not be exercisable. In the event that a Major Transaction is consummated during the Term, then the Holder shall have the right to exercise this Warrant and to make such exercise effective immediately prior to
the consummation of such Major Transaction. 
 Consummation of each of the following events shall constitute a “Major Transaction”: 

(A)    a consolidation, merger, exchange of shares, recapitalization, reorganization, business combination or other similar event,
following which the holders of Common Stock immediately preceding such consolidation, merger, exchange, recapitalization, reorganization, combination or event either (a) no longer hold a majority of the shares of Common Stock or a majority of
the voting power of the Successor Entity on a fully diluted basis or (b) no longer have the ability to elect a majority of the board of directors of the Company or the Successor Entity (collectively, a “Change of Control
Transaction”); or 
 (B)    a purchase, tender or exchange offer (other than any purchase, tender or exchange offer made by the
Holder or its Affiliates) made to the holders of outstanding shares of equity securities, such that following the consummation of such purchase, tender or exchange offer a Change of Control Transaction shall have occurred. 

(ii)    Notice of Major Transaction. At least fifteen (15) days prior to the consummation of any Major Transaction during the
Term, but, in any event, within two (2) Trading Days following the date of the 

 
public announcement of any Major Transaction which is reasonably expected to be consummated during the Term, the Company shall deliver written notice thereof via facsimile and overnight courier
to the Holder (a “Major Transaction Notice”). 
 For purposes hereof: 

“Eligible Market” means NASDAQ, the New York Stock Exchange, Inc., the NYSE Arca, the NASDAQ Capital Market, the NASDAQ Global Select Market or the
NYSE Alternext U.S. or any successor exchanges or markets thereof. 
 “Parent Entity” of a Person means an entity that, directly or indirectly,
controls the applicable Person and whose common stock or equivalent equity security is quoted or listed on an Eligible Market, or, if there is more than one such Person or Parent Entity, the Person or Parent Entity with the largest public market
capitalization as of the date of consummation of a Major Transaction. 
 “Person” means an individual, a limited liability company, a partnership,
a joint venture, a corporation, a trust, an unincorporated organization, any other entity and a government or any department or agency thereof. 

(d)    Adjustments: Additional Shares, Securities or Assets. In the event that at any time, as a result of an adjustment
made pursuant to this Section 5 or otherwise, Holder shall, upon Exercise of this Warrant, become entitled to receive shares and/or other securities or assets (other than Warrant Shares) then, wherever appropriate, all references herein to
Warrant Shares shall be deemed to refer to and include such shares and/or other securities or assets; and thereafter the number of such shares and/or other securities or assets shall be subject to adjustment from time to time in a manner and upon
terms as nearly equivalent as practicable to the provisions of this Section 5. 
 (e)    Other Adjustments. 

Preferred Shares. In the event that the Stockholder Approval (as defined in the Share Purchase Agreement) is not obtained prior to the Exercise of the
Warrant, this Warrant shall be exercisable for a number of shares of the Company’s Preferred Shares (as defined in the Share Purchase Agreement) that are convertible into the number of shares of Common Stock for which this Warrant would
otherwise have been exercisable if such Stockholder Approval had been obtained (and the Exercise Price shall be adjusted accordingly), and shall not be exercisable for the purchase of shares of Common Stock. 

(f)    Notice of Adjustments. Whenever the Exercise Price is adjusted pursuant to the terms of this Warrant, the Company
shall promptly mail to the Holder a notice (an “Exercise Price Adjustment Notice”) setting forth the Exercise Price after such adjustment and setting forth a statement of the facts requiring such adjustment. The Company shall, upon the
written request at any time of the Holder, furnish to such Holder a like Warrant setting forth (i) such adjustment or readjustment, (ii) the Exercise Price at the time in effect and (iii) the number of shares of Warrant Shares and the
amount, if any, of other securities or property which at the time would be received upon Exercise of the Warrant. For purposes of clarification, whether or not the Company provides an Exercise Price Adjustment Notice pursuant to this
Section 5(f), upon the occurrence of any event that leads to an adjustment of the Exercise Price, the Holder would be entitled to receive a number of Exercise Shares based upon the new Exercise Price, as adjusted, for exercises occurring on or
after the date of such adjustment, regardless of whether the Holder accurately refers to the adjusted Exercise Price in the Exercise Form. 
  

	6.	Fractional Interests.  

 No fractional shares or scrip representing fractional shares shall
be issuable upon the Exercise of this Warrant, but on Exercise of this Warrant, Holder may purchase only a whole number of shares of Warrant 

 
Shares. If, on Exercise of this Warrant, Holder would be entitled to a fractional share of Warrant Shares, such fractional share shall be disregarded and the Company shall calculate and pay to
the Holder an amount of cash in lieu of such fractional share, with such cash amount based on the Market Price (as defined in Section 3(a)(ii) above). If more than one Warrant shall be exercised concurrently by Holder, the number of whole
shares which shall be issuable upon exercise thereof shall be computed on the basis of the aggregate Warrants so exercised. 
  

	7.	Reservation of Shares.  

 From and after the date hereof, the Company shall at all times
reserve for issuance such number of authorized and unissued shares of Common Stock (or Series B Preferred Stock or other securities substituted therefor as herein above provided) as shall be sufficient for the Exercise of this Warrant. If at any
time the number of shares of equity securities authorized and reserved for issuance is below the number of shares sufficient to permit the Exercise of this Warrant (a “Share Authorization Failure”) (based on the Exercise Price in effect
from time to time), the Company will promptly take all corporate action reasonably necessary to authorize and reserve a sufficient number of shares, including, without limitation, calling a special meeting of stockholders to authorize additional
shares to meet the Company’s obligations under this Section 7, and using commercially reasonable efforts to obtain stockholder approval of an increase in such authorized number of shares. The Company covenants and agrees that upon the
Exercise of this Warrant, other than in the event of a Share Authorization Failure, if any, all Exercise Shares shall be duly and validly issued, fully paid and nonassessable and not subject to preemptive rights, rights of first refusal or similar
rights of any Person. 
  

	8.	Restrictions on Transfer.  

 (a)    Registration or Exemption
Required. This Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Regulation D and exempt from state registration or qualification under applicable state laws. Neither the
Warrant nor the Exercise Shares may be pledged, transferred, sold, assigned, hypothecated or otherwise disposed of except pursuant to an effective registration statement covering the resale of such securities or an exemption to the registration
requirements of the Securities Act and applicable state laws including, without limitation, a so-called “4(1) and a half” transaction. This Warrant shall be subject to the restrictions on transfer
set forth in the Shareholders Agreement. 
 (b)    Assignment. Subject to applicable securities laws and Section 8(a) (including
the Holder’s compliance with the transfer restrictions set forth in the Shareholders Agreement), the Holder may sell, transfer, assign, pledge, or otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a written notice to
Company, substantially in the form of the Assignment attached hereto as Exhibit B, indicating the Person or Persons to whom the Warrant shall be assigned and the respective number of warrants to be assigned to each assignee. The Company shall effect
the assignment within five (5) Trading Days (the “Transfer Delivery Period”), and shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of like tenor and terms for the appropriate number of shares. Subject to the
foregoing, this Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns of the Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of
this Warrant, and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or transfer is a so called “4(1) and half” transaction, the parties hereto agree that a legal
opinion from outside counsel for the Holder delivered to counsel for the Company shall be the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4(1) and half” transaction. 

	9.	Non-circumvention.  

 The Company hereby covenants
and agrees that the Company will not, by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other
voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be reasonably required to protect
the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Warrant Shares receivable upon the exercise of this Warrant above the Exercise Price then in effect,
and (ii) shall take all such actions as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Warrant Shares upon the exercise of this Warrant. 

 

	10.	Events of Failure.  

 The occurrence of each of the following shall be considered to be an
“Event of Failure.” 
 (i) A Delivery Failure Default occurs, where a “Delivery Failure Default” shall be deemed to have
occurred if the Company fails to use its reasonable best efforts to deliver Exercise Shares to the Holder within any applicable Delivery Period (other than due to the limitation contained in the provisions contained in the second paragraph of
Section 1); 
 (ii) A Legend Removal Failure occurs, where a “Legend Removal Failure” shall be deemed to have occurred if the
Company fails to use its reasonable best efforts to issue Exercise Shares without a restrictive legend, or fails to use it reasonable best efforts to remove a restrictive legend, when and as required under Section 2(e) hereof; 

(iii) a Transfer Delivery Failure occurs, where a “Transfer Delivery Failure” shall be deemed to have occurred if the Company fails
to use its reasonable best efforts to deliver a Warrant within any applicable Transfer Delivery Period; and 
 (iv) a Registration Failure
(as defined below). 
 For purposes hereof, “Registration Failure” means that (A) the Company fails to use its best efforts to file with the
SEC on or before the filing deadline any Registration Statement required to be filed pursuant to Section 4 of the Investor Rights Agreement, and (B) the Company fails to use commercially reasonable efforts to cause a Registration Statement
to be declared effective by the SEC, or fails to use commercially reasonable efforts to keep such Registration Statement current and effective as required in Section 4 of the Investor Rights Agreement, provided that in each case, a Registration
Failure shall be deemed to not have occurred if such Registration Failure results from a breach by any holder of a Registrable Security of its obligations pursuant to Section 4 of the Investor Rights Agreement. 

 

	11.	Default. 

 (a)    Events Of Default. Each of the following
events shall be considered to be an “Event of Default,” unless waived by the Holder: 
 (i) Failure To Effect Registration. With
respect to all Registration Failures, a Registration Failure occurs and remains uncured for a period of more than sixty (60) days after written notice thereof by Holder to the Company; provided that in each case, a Registration Failure
shall be deemed to not have occurred if such Registration Failure results from a breach by any holder of a Registrable Security of its obligations pursuant to Section 4 of the Investor Rights Agreement. 

 (ii) Failure To Deliver Warrant Shares. Other than as provided in Section 13(a) below, a Delivery
Failure (as defined above) occurs and the Company fails for any reason to effect delivery of the applicable Exercise Shares for a period of more than twenty (20) days after written notice thereof by Holder to the Company; or at any time, the
Company announces or states in writing that it will not honor its obligations to issue shares of Warrant Shares to the Holder upon Exercise by the Holder of the Exercise rights of the Holder in accordance with the terms of this Warrant. 

(iii) Legend Removal Failure. A Legend Removal Failure (as defined above) occurs and remains uncured for a period of thirty (30) days after
written notice thereof by Holder to the Company; and 
 (iv) Notice of Major Transaction. The Company has failed to satisfy the requirements of
Section 5(c)(iii) above. 
 (b)    Remedies, Other Obligations, Breaches And Injunctive Relief. The remedies provided
in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, the Share Purchase Agreement and the Investor Rights Agreement, at law or in equity (including a decree of specific performance and/or other
injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder
will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in
addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 

 

	12.	Reserved. 

  

	13.	Benefits of this Warrant. 

 Nothing in this Warrant shall be construed to confer upon any person
other than the Company and Holder any legal or equitable right, remedy or claim under this Warrant and this Warrant shall be for the sole and exclusive benefit of the Company and Holder. 

 

	14.	Governing Law. 

 All questions concerning the construction, validity, enforcement and
interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that (a) any and all
disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or
non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be referred to and finally resolved by arbitration under the Rules of Arbitration of the
London Court of International Arbitration (“LCIA Rules”) by one or more arbitrators appointed in accordance with the LCIA Rules (the “Arbitral Tribunal”); (b) the arbitration shall be conducted by a sole arbitrator unless either
party objects, in which case the arbitration shall be conducted by a panel of three arbitrators. Where the arbitration is to be conducted by a sole arbitrator, the parties shall attempt to agree upon the selection of the sole arbitrator. If they
cannot reach agreement within 30 days from the 

 
commencement of the arbitration, the sole arbitrator shall be appointed by the Court of the LCIA (the “LCIA Court”) in accordance with the LCIA Rules. Where the arbitration is to be
conducted by a panel of three arbitrators, each party shall nominate one arbitrator and the two party-nominated arbitrators shall then select the chairman of the Arbitral Tribunal. If the two party-nominated arbitrators are unable to do so within 30
days after the commencement of the arbitration or any mutually agreed extension thereof, the chairman shall be selected by the LCIA Court in accordance with the LCIA Rules; (c) the place of arbitration shall be London; (d) the language of
the arbitration shall be English; (e) each arbitrator shall be licensed to practice law in New York; (f) each party shall have the right to apply to any court of competent jurisdiction and/or to the Arbitral Tribunal for an order or award
of interim, provisional or conservatory measures in order to maintain the status quo or to protect its rights or property pending arbitration pursuant to this Agreement or for the purpose of compelling a party to arbitrate and seeking temporary or
preliminary relief in aid of an arbitration hereunder, and any such application shall not be deemed incompatible with, or a waiver of, the parties’ agreement to arbitrate; (g) the Arbitral Tribunal shall have power to take whatever interim
measures it deems necessary, including injunctive relief, specific performance and other equitable relief, including in accordance with the provisions set forth in Section 11(b) of this Agreement. (h) the award rendered by the Arbitral Tribunal
shall be final and binding between the parties and not subject to appeal or other recourse; and (i) recognition and enforcement of any award rendered by the Arbitral Tribunal may be sought in any court of competent jurisdiction. 

 

	15.	Loss of Warrant. 

 Upon receipt by the Company of evidence of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction) of indemnity or security reasonably satisfactory to the Company, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver a
new Warrant of like tenor and date. 
  

	16.	Notice or Demands. 

 Notices or demands pursuant to this Warrant to be given or made by Holder to
or on the Company shall be sufficiently given or made if sent by certified or registered mail, return receipt requested, postage prepaid or via overnight delivery with a nationally recognized courier service, and addressed, until another address is
designated in writing by the Company, to the address set forth in Section 2(a) above. Notices or demands pursuant to this Warrant to be given or made by the Company to or on Holder shall be sufficiently given or made if sent by certified or

(b)    Subject to subsections (d), (e) and (f) of this Section 2.1, in connection with each meeting of
stockholders of the Company at which Directors are to be elected to serve on the Board, the Company shall take all necessary steps to nominate at least such number of individuals nominated by the Investor for election to the Board as the Investor

appointment of such Investor Directors to the Board, including using its reasonable best efforts to cause the Board to unanimously recommend that the stockholders of the Company vote in favor of each Investor Director for election to the Board. If,
for any reason, a candidate designated as an Investor Director is reasonably determined by the Board to be unqualified to serve on the Board because such appointment would constitute a breach of the fiduciary duties of the Board or applicable Law or
stock exchange requirements, the Investor shall have the right to designate an alternative Investor Director to be so appointed, and the provisions of this Section 2.1(a) shall apply, mutatis mutandis, to such alternative Investor Director;

  
 8 

 (c)    Each appointed or elected Investor Director will hold his or her

(calculated on a fully-diluted as-converted basis and excluding all Securities issued pursuant to the New Issuance Exceptions); (ii) two (2) Investor Directors pursuant to this Section 2.1 for so
long as the Investor owns Securities representing, in the aggregate, no less than twenty percent (20%) of the total outstanding Common Stock (calculated on a fully-diluted as-converted basis and excluding all
Securities issued pursuant to the New Issuance Exceptions), and (iii) one (1) Investor Director pursuant to this Section 2.1 for so long as the Investor owns Securities representing, in the aggregate, no less than ten percent (10%) of the
total outstanding Common Stock (calculated on a fully-diluted as-converted basis and excluding all Securities issued pursuant to the New Issuance Exceptions). Upon such time as the Investor has exercised the
Warrant in full, then (A) the Company shall, immediately upon the exercise of the Warrant, cause the appointment to the Board of one (1) additional individual nominated by the Investor or such additional numbers of individuals so the
Investor Directors shall constitute the majority of the directors serving on the Board, and (B) for so long as the Investor owns Securities representing, in the aggregate, no less than forty percent (40%) of the total outstanding Common Stock
(calculated on a fully-diluted as-converted basis and excluding all Securities issued pursuant to the New Issuance Exceptions), it shall have the right to designate at least four (4) Investor Directors or

applicable Law or stock exchange requirements or from acting in good faith in accordance with the Company Certificate or the Company Bylaws, while giving due consideration to the intent of this Agreement. The Board shall have no obligation to
appoint or nominate any Investor Director if such appointment or nomination would violate applicable Law or stock exchange requirements or result in a breach by the Board of its fiduciary duties to its stockholders; provided, however, that the

sessions of Independent Directors) of the Nasdaq Listing Rules, provided further, that irrespective of whether the Company is a “controlled company” within the meaning of the Nasdaq Listing Rules, the Investor shall have the right
to nominate all of its Investor Directors as non-Independent Directors serving on the Board, unless prohibited by the applicable Laws and stock exchange requirements.

(g)    The Company recognizes that individuals associated with the Investor and its Affiliates will be Investor Directors
and serve on the Board from time to time, and that such individuals (i) will from time to time receive non-public information concerning the Company and its Subsidiaries, and (ii) may (subject to the
obligation to maintain the confidentiality of such information in accordance with Section 7.1) share such information with other individuals associated with the Investor and its Affiliates. Such sharing will be for the dual purpose of
facilitating support to such individuals in their capacity as directors and enabling the Investor, as a stockholder, to better evaluate the Company’s performance and prospects, but not for any other purpose to the detriment of the Company and
its Affiliates. Notwithstanding the foregoing, the Investor Directors will not share any information if the Company informs the Investor Directors that such sharing could be reasonably expected to compromise or otherwise adversely affect the
Company’s and its Affiliates ability to assert any attorney/client privilege or similar rights. The Company hereby irrevocably consents to such sharing; and 

(h)    So long as any Investor Director serves on the Board, the Company at its sole cost and expense shall:

vice president of the 

  
 10 

 
Company at the Closing or immediately thereafter but no later than one (1) month after Closing, subject to obtaining the requisite visa and work permit required for such Investor Vice
President if needed. In the event that the Investor Vice President cannot be appointed by the Company within the prescribed timeline due to the failure or delay of obtaining the requisite visa or work permit on time the Company shall appoint the
Investor Vice President immediately upon obtaining the requisite visa and work permit without delay. The Investor Vice President shall be invited to attend all executive meetings of the Company and shall receive all relevant documents and
information pertaining to such meetings.

ARTICLE IV 
 REGISTRATION
RIGHTS 
 Section 4.1    Demand Registration. 

(a)    Request by the Investor. Subject to the terms of this ARTICLE IV, for so long as the Investor beneficially
owns a number of Common Stock (including Common Stock issuable upon conversion of the Preferred Stock) that, in aggregate, is equal to at least five percent (5%) of the outstanding shares of Common Stock of the Company, the Investor may by written
notice to the Company (a “Demand Notice”) request the Company to effect the Registration of all or part of the Registrable Securities owned by the Investor. Each request must specify the number

  
 13 

 
of Registrable Securities for which registration is requested and the intended method or methods of distribution thereof. Upon receipt of such a request, the Company shall as soon as practicable
cause the Registrable Securities specified in such Demand Notice to be Registered and/or qualified for sale and distribution in such jurisdictions as the Investor may reasonably request, to the extent necessary to permit the disposition (in
accordance with the intended methods as aforesaid). The Company shall use its reasonable best efforts to cause such Registration and/or qualification to be complete as soon as practicable, but in no event later than ninety (90) days, after
receipt of the Demand Notice. The Company shall be obligated to effect no more than one (1) Registration requested by the Investor during any twelve-month period; provided that a Registration shall not be deemed to have been effected
under this Section 4.1 if (i) less than all Registrable Securities set forth in such Demand Notice are Registered in such Registration or (ii) prior to the sale of all of the Registrable Securities included in the applicable
registration relating to such request, such Registration is adversely affected by any stop order, injunction or other order or requirement of the Commission (other than any such stop order, injunction, or other requirement of the Commission prompted
by act or omission of the Investor). The Investor acknowledges and agrees that the Company is not current in its reporting obligations under the U.S. Securities Laws and that it will not be able to effect a Registration while the Company is not
current in its reporting obligations under the U.S. Securities Laws, provided that the Company shall use its reasonable best efforts to become current in its reporting obligations under the U.S. Securities Laws as soon as practicable. 

(b)    Limitation. The Company shall not be obligated to Register or qualify Registrable Securities pursuant to
Section 4.1(a) above, if the aggregate offering price of the Registrable Securities to be Registered under the Demand Notice is less than $3,000,000. 

(c)    Right of Deferral. If, after receiving a Demand Notice, the Company furnishes to the Investor a certificate
signed by an officer or director of the Company stating that, in the good faith judgment of the Board, it would materially interfere with a bona fide business, acquisition or divestiture or financing transaction of the Company or is reasonably
likely to require premature disclosure of information, the premature disclosure of which would reasonably be expected to materially and adversely affect the Company, then the Company shall have the right to defer such filing for a period not
exceeding ninety (90) days from the receipt of a Demand Notice; provided, that the Company shall not utilize this right more than once in any twelve (12) month period; and provided further that the Company shall not Register
any other Securities during such ninety (90) day period (other than Exempt Registrations). In the event that the Company exercises such right, the Investor shall be entitled to withdraw its Demand Notice by written notice to the Company and
such withdrawn Demand Notice shall not constitute a request by such Investor to effect a Registration under Section 4.1(a). 

(d)    Shelf Registration. The Company shall use its reasonable best efforts to facilitate its eligibility under
U.S. Securities Laws to use a Shelf Registration Statement. Upon the written request of the Investor, and provided that the Company is eligible to use a Shelf Registration Statement, the Company shall file a Shelf Registration Statement
covering all of the Registrable Securities of the Investor as soon as practicable, but in no event later than thirty (30) days, after receipt of such request. Unless such Shelf Registration Statement shall become automatically effective, the
Company shall use its reasonable best efforts to cause the Shelf Registration Statement to become or be declared effective by the Commission for all of the Registrable 

  
 14 

 
Securities of the Investor as promptly as practicable after the filing thereof. The Company shall use its reasonable best efforts to keep such Shelf Registration Statement (or a successor
Registration Statement filed with respect to the Registrable Securities) continuously effective (including by filing a new Shelf Registration Statement if the initial Shelf Registration Statement expires) in order to permit the prospectus or any
prospectus supplement related thereto to be lawfully delivered and the Shelf Registration Statement useable for resale of such Registrable Securities until such Registration Securities may be sold without restriction or limitation under Rule 144.

 (e)    Underwriting Election. The Investor may request to distribute its or its Affiliates’ Registrable
Securities in an underwritten offering by notifying the Company in writing (the “Underwriting Election”). Upon receipt of an Underwriting Election, the Company shall use its reasonable best efforts to cause such Registration or
“takedown” of such Shelf Registration Statement to be in the form of a firm commitment underwritten offering and the managing underwriters for such offering shall be internationally reputable investment banking firms selected by the
Company. If such investment banking firm is not one of the bulge bracket investment banks, the investment banking firm selected by the Company should be reasonably acceptable to the Investor. 

Section 4.2    Piggyback Registrations. 

(a)    Registration of the Company’s Securities. Subject to Section 4.2 (c) hereof, for so long as the
Investor beneficially owns a number of Common Stock (including Common Stock issuable upon conversion of the Preferred Stock) that, in aggregate, is equal to at least five percent (5%) of the Common Stock of the Company, if the Company proposes to
Register for its own account any of its Securities (other than a registration statement on S-4 or S-8 or Shelf Registration Statement (or any substitute form that may be
adopted by the SEC) for securities to be offered in a transaction of the type referred to in Rule 145 under the Securities Act or to employees of the Company pursuant to any employee benefit plan, respectively), or for the account of any holder of
Securities any of such holder’s Securities, in connection with the public offering of such Securities, the Company shall promptly give the Investor written notice of such Registration and, upon the written request of the Investor given within
fifteen (15) days after delivery of such notice, the Company shall use its reasonable best efforts to include in such Registration any Registrable Securities thereby requested by the Investor. If the Investor decides not to include all or any
of its Registrable Securities in such Registration by the Company, the Investor shall nevertheless continue to have the right to include any Registrable Securities in any subsequent Registration Statement or Registration Statements as may be filed
by the Company with respect to offerings of its Securities upon the terms and conditions set forth herein. 

(b)    Right to Terminate Registration. The Company shall have the right to terminate or withdraw any Registration
that was initiated by it under this Section 4.2 prior to the effectiveness of such Registration whether or not the Investor has elected to participate therein. The expenses of such withdrawn Registration shall be borne by the Company, in
accordance with Section 4.4 hereof. 
 (c)    Underwriting Requirements. In connection with any offering
involving an underwriting of the Company’s Securities, the Company shall not be required to Register the 

  
 15 

 
Registrable Securities of the Investor under this Section 4.2 unless the Investor’s Registrable Securities are included in the underwriting and the Investor enters into an underwriting
agreement in customary form with the underwriters and setting forth such terms for the underwriting. In the event the underwriters advise the Investor seeking Registration of Registrable Securities pursuant to this Section 4.2 in writing that,
in their reasonable opinion, market factors (including the aggregate number of Registrable Securities requested to be Registered, the general condition of the market, and the status of the Persons proposing to sell securities pursuant to the
Registration) require a limitation of the number of Securities to be underwritten, the underwriters may exclude some or all Registrable Securities from the Registration and underwriting; provided that the Company shall include the
Company’s Securities in such registration, in the priority listed below: (i) in the event the Company initiated such piggyback registration, the Company shall include in such piggyback registration first, the Securities the Company
proposes to register and second, the Securities of all other selling security holders, including the Registrable Securities requested to be included by the Investor to be included in such piggyback registration in an amount that, together
with the Securities the Company proposes to register, shall not exceed the maximum offering size and shall be allocated among such selling security holders on a pro rata basis; and (ii) in the event any holder of Securities initiated such
piggyback registration, the Company shall include in such piggyback registration first, the Securities such initiating security holder proposes to register, second, pro rata among any other Securities requested to be registered
pursuant to a contractual right of registration (including Securities requested to be Registered by the Investor pursuant to this Section 4.2) and third, any Securities the Company proposes to register, in an amount that, together with
the Securities the initiating security holder and the other selling security holders propose to register, shall not exceed the maximum offering size; provided further that the number of the Registrable Securities that are included in an
underwriting must not be reduced below thirty percent (30%) of the total number of Registrable Securities requested by the Investor to be included in the Registration. If the Investor (or its Affiliate) disapproves of the terms of any underwriting,
the Investor (or such Affiliate) may elect to withdraw therefrom by written notice to the Company and the underwriters delivered at least ten (10) days prior to the effective date of the Registration Statement. Any Registrable Securities
excluded or withdrawn from the underwriting shall be withdrawn from the Registration. 
 (d)    Exempt
Registration. The Company shall have no obligation to Register any Registrable Securities under this Section 4.2 in connection with an Exempt Registration. 

(e)    Not a Demand Registration. Registration pursuant to this Section 4.2 shall not be deemed to be a
Registration as described in Section 4.1(a). There shall be no limit on the number of times the Investor may participate in Registration of Registrable Securities under this Section 4.2. 

Section 4.3    Procedures. Whenever required under this ARTICLE IV to effect the Registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably possible: 
 (a)    prepare and file with the
Commission a Registration Statement with respect to those Registrable Securities and use its reasonable best efforts to cause that Registration Statement to become effective, and, keep the Registration Statement effective and current for the

Registrable Securities; provided, that a Shelf Registration shall be kept effective and current for the earlier of eighteen (18) months or until the date on which all Registrable Securities included in such Registration Statement shall

service of process in any such jurisdictions; and provided further that in the event any jurisdiction in which the Securities shall be qualified imposes a non-waivable requirement that expenses incurred
in connection with the qualification of the Securities be borne by the selling Shareholders, those expenses shall be payable by such selling Shareholders on a pro rata basis; 

(e)    in the event of any underwritten public offering, enter into and perform its obligations under an underwriting
agreement in customary form (including indemnification provisions and procedures customary in underwritten offerings) and take all such other actions reasonably requested by the underwriters to expedite or facilitate the underwritten disposition of

letters to be in customary form and covering matters of the type customarily covered in “comfort” letters and (iv) deliver such documents and certificates as may be reasonably requested by the Investor

  
 17 

 
whose Registrable Securities being sold in connection therewith, its counsel and the underwriters to evidence the continued validity of the representations and warranties made pursuant to clause
(i) above and to evidence compliance with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company; 

(f)    promptly notify the Investor: (i) when the Registration Statement, the prospectus or any prospectus supplement
related thereto or post-effective amendment to the Registration Statement has been filed, and, with respect to the Registration Statement or any post-effective amendment thereto, when the same has become effective; (ii) of any request by the
Commission for amendments or supplements to the Registration Statement or the prospectus used in connection with the Registration Statement or any additional information; (iii) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceedings by any Person for that purpose; and (iv) of the receipt by the Company of any written notification with respect to the suspension of the qualification of any
Registrable Securities for sale in any jurisdiction or the initiation or overt threat of any proceeding for such purpose; 

(g)    notify the Investor, at any time when a prospectus relating thereto is required to be delivered under U.S.
Securities Laws, of the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and promptly prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus and file any
other required document, and prepare and furnish to the Investor and underwriters a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary, so that, as thereafter delivered to the Investor and any
underwriters, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then
existing; 
 (h)    use its reasonable best efforts to prevent the issuance or obtain the withdrawal of any order
suspending the effectiveness of any Registration Statement at the earliest practicable time; 
 (i)    if any such
Registration Statement refers to the Investor by name or otherwise as the holder of any Securities, and if the Investor is advised by counsel that it is or may be deemed to be a control person in relation to, or an Affiliate of, the Company, then
the Investor shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to the Investor, to the effect that the holding by the Investor is not to be construed as a recommendation by the Investor of
the investment quality of the Company’s Securities covered thereby and that such holding does not imply that the Investor will assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to
the Investor by name or otherwise is not, based on the advice of the counsels to the Company, the Investor and if applicable, the underwriters, required by the Securities Act or any similar federal statute then in force, the deletion of the
reference to the Investor;

physical stock certificates into book-entry form in accordance with any procedures reasonably requested by the Investor or underwriters; 

(n)    cooperate with the Investor and the underwriters to facilitate the timely delivery of Registrable Securities to be

 Section 4.5    Indemnification. 

(a)    Company Indemnification. 

(i)    To the extent permitted by applicable Law, the Company will indemnify and hold harmless the Investor, each Person
who controls the Investor (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and their respective officers, directors, members, managers, shareholders, agents and employees and any underwriter for
the Company and each Person who controls such underwriter (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) from and against all losses, claims, costs, damages or liabilities (whether joint or
several) to which they may become subject under applicable Laws or otherwise, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or
violations (each a “Violation”): (i) any untrue statement (or alleged untrue statement) of a material fact contained in such Registration Statement, including any preliminary prospectus or Final Prospectus contained therein or any
amendments or supplements thereto, (ii) the omission (or alleged omission) to state in the Registration Statement, including any preliminary prospectus or Final Prospectus contained therein or any amendments or supplements thereto, a material
fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of U.S. Securities Laws, or any rule or regulation promulgated under U.S. Securities Laws.
The Company will reimburse any Person intended to be indemnified pursuant to this Section 4.5(a) for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or
action. 
 (ii)    The indemnity agreement contained in this Section 4.5(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld or delayed), nor shall the Company be liable for any such loss,
claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such Registration by the
Investor, underwriter or controlling Person. 
 (iii)    The foregoing indemnity of the Company is subject to the
condition that, insofar as they relate to any defect in a preliminary prospectus but such defect has been eliminated or remedied in the amended prospectus on file with the Commission at the time the applicable Registration becomes effective (the
“Final Prospectus”), such indemnity shall not inure to the benefit of any Person if a copy of the Final Prospectus was timely furnished to the Investor or underwriter and was not furnished to the Person asserting the loss,
liability, claims or damages at or prior to the time such action is required by the Securities Act. 

(b)    Investor Indemnification. 

(i)    To the extent permitted by applicable Law, the Investor will indemnify and hold harmless the Company, each Person
who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) and each of their respective officers, directors, partners, members, managers, shareholders, accountants, attorneys,
agents and 

  
 20 

 
employees from and against all losses, claims, costs, damages or liabilities (whether joint or several) to which any of the foregoing Persons may become subject, under U.S. Securities Laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based on any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement,
including any preliminary prospectus or Final Prospectus contained therein or any amendments or supplements thereto, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse any Person intended to be indemnified pursuant to this Section 4.5(b) for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such claim,
loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such Registration Statement, including any preliminary
prospectus or Final Prospectus contained therein or any amendments or supplements thereto, in reliance upon and in conformity with written information furnished to the Company and signed by the Investor and intended to be specifically for use
therein. 
 (ii)    The indemnity contained in this Section 4.5(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected without the consent of the Investor (which consent shall not be unreasonably withheld), and in no event shall the aggregate indemnity under this Section 4.5(b) (including
any reimbursement of any expenses) exceed the net proceeds (less underwriting discounts and selling commissions) from the offering received by the Investor. The Investor will not be required to enter into any agreement or undertaking in connection
with any Registration providing for any indemnification or contribution on the part of the Investor greater than the Investor’s obligations under this Section 4.5. 

(c)    Notice of Indemnification Claim. Promptly after receipt by an indemnified party under Section 4.5(a) or
Section 4.5(b) of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under Section 4.5(a) or Section 4.5(b), deliver
to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in and to assume the defense thereof with counsel reasonably satisfactory to the indemnifying party. An indemnified
party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonably incurred fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such
proceeding. It is understood and agreed that the Indemnifying Party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any
local counsel) for all Indemnified Parties and that all such fees and expenses shall be reimbursed as they are incurred. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action,
if prejudicial to its ability to defend such action, shall relieve such indemnifying party of liability to the indemnified party under this Section 4.5to the extent the indemnifying party is so prejudiced, but the omission to deliver written notice
to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 4.5. 

  
 21 

 (d)    Contribution. If any indemnification provided for in Section
4.5(a) or Section 4.5(b) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense 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 hand, in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material
fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. The parties hereto
agree that it would not be just and equitable if contribution pursuant to this Section 4.5(b) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the
immediately preceding paragraph. Notwithstanding the provisions of this Section 4.5(d), (i) the Investor as an indemnifying party shall not be required to contribute any amount in excess of the amount that the Investor has otherwise been, or would
otherwise be, required to pay pursuant to this Section 4.5(d) by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to a contribution from any Person who was not guilty of such fraudulent misrepresentation. 

Section 4.6    Reports under the Exchange Act. With a view to making available to the Investor the benefits of
Rule 144 or pursuant to a Registration on a Shelf Registration Statement, the Company agrees to use reasonable best efforts to: 

(a)    make and keep public information available, as those terms are understood and defined in Rule 144 under the
Securities Act, at all times so long as the Company remains subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act; 

(b)    file with the Commission in a timely manner all reports and other documents required of the Company under all U.S.
Securities Laws; 
 (c)    promptly furnish to the Investor upon request (i) a written statement by the Company
that it has complied with the reporting requirements of all U.S. Securities Laws or, at any time after so qualified, that it qualifies as a registrant whose securities may be resold pursuant to a Shelf Registration Statement, (ii) a copy of the
most recent annual or quarterly report of the Company and such other reports and documents as may be filed by the Company with the Commission, and (iii) such other information as may be reasonably requested in availing the Investor of any rule
or regulation of the Commission, that permits the selling of any such securities without Registration or pursuant to a Shelf Registration Statement; and 

  
 22 

 (d)    if the Company is no longer subject to the periodic reporting
requirements under Section 13 or 15(d) of the Exchange Act, prepare and furnish to the Investor and make publicly available in accordance with Rule 144(c) such information as is required for the Investor to sell shares under Rule 144, and take
such further action as any holder of the Investor shares may reasonably request to the extent required from time to time to enable such Person to sell the shares without registration under the Securities Act within the limitation of the exemptions
provided by Rule 144. 
 Section 4.7    Limitations on Subsequent Registration Rights. From and after the
date of this Agreement, the Company shall not, without the approval of the Investor, enter into any agreement with any holder or prospective holder of any Securities that would (i) grant such holder or prospective holder any registration rights
more favorable to such holder or prospective holder than those rights granted pursuant to this ARTICLE IV, (ii) allow such holder or prospective holder to demand Registration of their securities, unless under the terms of such agreement, such
holder or prospective holder may demand such Securities in any such Registration only to the extent that the demand of such securities will not reduce the amount of the Registrable Securities of the Investor that are demanded or (iii) allow
such holder or prospective holder to include such securities in any Registration filed under Section 4.1(d), Section 4.1(e) or Section 4.2, unless under the terms of such agreement such holder or prospective holder may include such Securities
in any such Registration only to the extent that the inclusion of such securities will not reduce the amount of the Registrable Securities of the Investor that are included. 

Section 4.8    Termination of the Investor’s Registration Rights. The right of the Investor
to request Registration or inclusion of Registrable Securities in any Registration pursuant to Section 4.1 or Section 4.2 shall terminate when all of the Investor’s Registrable Securities may be sold without restriction or limitation
under Rule 144. 
 Section 4.9    Assignment of the Investor’s Registration Rights. The
rights and obligations of the Investor under this ARTICLE IV may be assigned by the Investor to any transferee or assignee of any of the Investor’s Registrable Securities; provided that: (a) the Company is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such transferee or assignee and the Securities with respect to which such registration rights are being assigned and (b) such transferee or assignee agrees in writing to be
bound by and subject to the terms and conditions of this ARTICLE IV. 
 ARTICLE V 

PREEMPTIVE RIGHT 

Section 5.1    At any time the Company proposes to issue any Securities or transfer any Securities that have been
repurchased from the open market and held under the Company’s brokerage account or otherwise held under the Company’s name, including any Common Stock (the “New Securities”), other than: (i) the New Issuance
Exceptions and (ii) the issuance of Common Stock on a pro rata basis in connection with the payment of any share dividends, the Company shall notify the Investor in writing of such proposal (an “Issue Notice”). The Issue Notice
shall specify the number and type of New Securities to be offered by the Company and all material terms and conditions of the proposed offer (including the proposed price or range of prices) per New Security. 

  
 23 

 Section 5.2    The Investor shall have the right to purchase, or to
purchase through an Affiliate, up to a number of New Securities so as to enable the Investor to beneficially hold, after the issue of the New Securities which are the subject to the Issue Notice, a pro rata portion of the New Securities equal to the
percentage of the issued and outstanding Common Stock then beneficially owned by the Investor prior to the issuance of the New Securities upon the same terms and conditions set forth in the Issue Notice, by giving written notice to the Company of
the exercise of this right within thirty (30) days of Investor’s receipt of the Issue Notice (the “Election Notice”). If such notice is not given by the Investor within such thirty (30) days thereof, the Investor
shall be deemed to have elected not to exercise its preemptive rights under this ARTICLE V with respect to the issuance described in that specific Issue Notice. 

Section 5.3    If the Investor (or its Affiliate) exercises its preemptive rights under this ARTICLE V, the closing
of the purchase of the New Securities with respect to which such right has been exercised (the “Preemptive Rights Closing Date”) shall take place at the time of the closing of the issuance or transfer of the New Securities, which
may not be earlier than ten (10) Trading Days after the giving of the Election Notice, provided that the Preemptive Rights Closing Date may be extended for a maximum of sixty (60) Trading Days to the extent required to comply with
applicable Laws (including receipt of any required regulatory approvals). The Company and the Investor (or its Affiliate exercising preemptive rights under this ARTICLE V) will use commercially reasonable efforts to secure any required regulatory or
shareholder approvals or other consents in a timely manner, and to comply with any applicable Law necessary in connection with the offer, sale and purchase of, such New Securities. 

Section 5.4    In the event that the Investor (or its Affiliate) fails to exercise its preemptive rights under this
ARTICLE V within such thirty (30) days period, or in the event that the Investor fails to consummate the purchase of such New Securities within the specified period of time pursuant to Section 5.3 (other than as a result of breach or fault
of the Company), the Company shall thereafter be entitled to issue and sell within sixty (60) Trading Days the New Securities not elected to be purchased by the Investor (or its Affiliate) pursuant its preemptive rights to this ARTICLE V, at a
price no less than that specified in the Issue Notice, and otherwise upon terms and conditions no more favorable in the aggregate to any purchaser of such New Securities than were specified in the Issue Notice. In the event the Company has not
issued and sold such New Securities within such sixty (60) Trading Day period, the Company shall not thereafter offer, issue or sell such New Securities without first offering such New Securities to the Investor in the manner provided in this
ARTICLE V. 
 Section 5.5    In the case of the offering of New Securities for a consideration in whole or in part
other than cash, including securities acquired in exchange therefor, the consideration other than cash shall be deemed to be the fair value thereof as determined in good faith by the Board; provided, however, that such fair value as
determined by the Board shall not exceed the aggregate market price of the New Securities being offered as of the date the Board authorizes the offering of such New Securities.

seventy-five percent (75%) of the members of the Board, each of the Investor and Founders agree not to, and to cause their respective Affiliates not to, (i) acquire, offer to acquire, or agree to acquire, by purchase or otherwise, any
Securities (or beneficial ownership thereof), or rights or options to acquire any Securities (or beneficial ownership thereof), or any assets or businesses of the Company or its Subsidiaries constituting a significant portion of the consolidated
assets of the Company and its Subsidiaries; (ii) make any public announcement with respect to, or submit a proposal for or offer of (with or without conditions), any merger, consolidation, tender or exchange offer, amalgamation, scheme of
arrangement, recapitalization, reorganization, liquidation, dissolution, business combination, issuance or repurchase of Securities (including any tender offer) or other extraordinary transaction involving the Company, any of the assets of the
Company or its Subsidiaries constituting a significant portion of the consolidated assets of the Company and its Subsidiaries; (iii) advise, encourage, support or influence any Person (except the Board) with respect to any of the foregoing;
(iv) initiate, or in any way participate, directly or indirectly, in any “solicitation” of “proxies” to vote (as such terms are used in the rules of the SEC), or seek to advise or influence any Person or entity with respect
to the voting of any Voting Securities of the Company, or form, join or in any way participate in a group for the purpose of the voting of any Voting Securities of the Company (other than as contemplated hereunder or under the Shareholders
Agreement); or (v) publicly request the Company or Board amend or waive any provision of this paragraph (including this sentence), or contest the validity of this paragraph (including this sentence); provided, that nothing in the
preceding clauses shall (A) restrict the Investor from making a private, non-public, proposal to the Board for any of such matters, (B) apply to any “beneficial ownership” of Securities
acquired or deemed to be acquired by virtue of any of the arrangements expressly contemplated under the Transaction Documents, including any voting agreements contemplated under the Shareholders Agreement, or (C) in any way be deemed to require
any Investor Director to take (or omitting to take) any actions in a manner he or she reasonably believes would be inconsistent with the fiduciary duties of the Directors under applicable Law (or obligate the Investor to cause any Investor Director
to act or omit to act in a manner in which such Investor Director reasonably believes would be inconsistent with the fiduciary duties of the Directors under applicable Law). In addition to any other available remedies, the Investor, Founders or any
of their Affiliates, successors or permitted assigns shall not have the right to vote or grant consents with respect to any Securities acquired in violation of this Section 6.4(i) and agrees to promptly sell any such Securities and shall be
restrained from voting or granting consents with respect to all of its Securities at any annual or special meeting of the stockholders of the Company, however called, or in connection with any action by written consent in lieu of any such annual or
special meeting of stockholders of the Company in violation of this Section 6.4(iv) and any decision, action or transaction by such Person made or effected in violation of this Section 6.4(iv) shall be null and void ab initio. Notwithstanding
the foregoing, if following any Permitted Purchase made by the Founders, the Investor and its 

  
 26 

 
Affiliates and their respective transferees no longer hold, in the aggregate, the largest number of shares of Common Stock of the Company (assuming the conversion of Series B Preferred Stock into
Common Stock, and with the Founders deemed as one single shareholder for the purpose of such determination), the Investor shall have the right to purchase such number of shares of Common Stock or other Securities so as to enable the Investor and its
Affiliates and their respective transferees to become the holders, in the aggregate, of the largest number of shares of Common Stock of the Company (assuming the conversion of Series B Preferred Stock into Common Stock, and with the Founders deemed
as one single shareholder for the purpose of such determination), any such purchases shall not be deemed to violate the provision of this Section 6.4. 

Section 6.5    Agreement to Issue Additional Stock. The Investor hereby agrees that, to the extent not
reserved for issuance in December 2016 prior to the Closing, the Company may, at its discretion, reserve Securities for issuance under its existing employee equity incentive compensation plans or the Key Employee Retention Program as defined in the
Share Purchase Agreement, and issue such reserved Securities to its employees pursuant to such employee incentive compensation plan(s); provided, however, that any such reservation or issuance of new Securities shall not exceed 500,000 shares
of Common Stock or any other Securities which by its terms are convertible into or exchangeable or exercisable for equivalent amount of Common Stock. Notwithstanding the foregoing, if following the issuance of such new Securities to the employees,
the Investor and its Affiliates and their respective transferees no longer hold, in the aggregate, the largest number of shares of Common Stock of the Company (assuming the conversion of Series B Preferred Stock into Common Stock, and with the
Founders deemed as one single shareholder for the purpose of such determination), the Investor shall have the right to purchase such number of shares of Common Stock or other Securities so as to enable the Investor and its Affiliates and their
respective transferees to become the holders, in the aggregate, of the largest number of shares of Common Stock of the Company (assuming the conversion of Series B Preferred Stock into Common Stock, and with the Founders deemed as one single
shareholder for the purpose of such determination), any such purposes shall not be deemed to violate the provision of Section 6.4. 

ARTICLE VII 
 GENERAL
PROVISIONS 
 Section 7.1    Confidentiality. Each of the Company and the Investor hereby agrees that it
will, and will cause its respective Affiliates and its and their respective representatives to hold in strict confidence any non-public records, books, contracts, instruments, computer data and other data and
information concerning the other parties hereto, whether in written, verbal, graphic, electronic or any other form provided by any party hereto (except to the extent that such information has been (a) previously known by such party on a non-confidential basis from a source other than the other parties hereto or its representatives, provided that such source is not prohibited from disclosing such information to such party or its representatives by a
contractual, legal or fiduciary obligation to the other parties hereto or its representatives, (b) in the public domain through no breach of this Agreement by such party, (c) independently developed by such party or on its behalf, or
(d) later lawfully acquired from other sources) (the “Confidential Information”). In the event that a party hereto is requested or required by Law, Governmental Authority or other applicable judicial or governmental order to
disclose any Confidential 

  
 27 

 
Information concerning any of the other parties hereto, such party shall, to the extent legally permissible, provide the other parties with sufficient advance written notice of such request or
requirement and, if requested by another party hereto (at such other party’s sole expense) assist such other party in seeking a protective order or other appropriate remedy to limit or minimize such disclosure. 

Section 7.2    Termination. Unless expressly provided otherwise herein, in addition to the other termination
provisions in this Agreement, this Agreement shall terminate, and have no further force and effect upon a written agreement to that effect, signed by all parties hereto, provided that, notwithstanding the foregoing, following the Closing,
(1) ARTICLE IV shall survive (including with respect to any transferee or assignee of the Investor’s Registrable Securities to whom the rights and obligations of the Investor under ARTICLE IV were assigned in accordance with
Section 4.9) any termination of this Agreement until the specific provisions thereof terminate in accordance with their express terms, (2) ARTICLE V shall survive any termination of this Agreement until the specific provisions thereof
terminate in accordance with their express terms, and (3) the Investor’s rights hereunder shall terminate to the extent that the Investor ceases to own Securities representing, in the aggregate, at least five percent (5%) of the total
outstanding Common Stock (calculated on a fully-diluted as-converted basis and excluding all Securities issued pursuant to the New Issuance Exceptions). 

Section 7.3    Notices. Except as may be otherwise provided herein, any notices, consents, waivers or other
communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (a) upon receipt, when delivered personally; (b) upon receipt, when sent by email (provided
confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (c) one (1) Business Day after deposit with an internationally recognized overnight courier service; in each case properly

A party may change or supplement the addresses given above, or designate additional addresses, for purposes of this Section 7.3 by giving
the other parties written notice of the new address in the manner set forth above. 

Section 7.4    Reserved. 

Section 7.5    Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws
of the State of New York, without regard to principles of conflict of laws thereunder other than New York General Obligations Law Section 5-1401. 

Section 7.6    Dispute Resolution. 

(a)    Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of,
relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration
provision) shall be referred to and finally resolved by arbitration under the Rules of Arbitration of the London Court of International Arbitration (“LCIA Rules”) by one or more arbitrators appointed in accordance with the LCIA
Rules (the “Arbitral Tribunal”); 
 (b)    The arbitration shall be conducted by a sole arbitrator
unless either party objects, in which case the arbitration shall be conducted by a panel of three arbitrators. Where the 

  
 29 

 
arbitration is to be conducted by a sole arbitrator, the parties shall attempt to agree upon the selection of the sole arbitrator. If they cannot reach agreement within 30 days from the
commencement of the arbitration, the sole arbitrator shall be appointed by the Court of the LCIA (the “LCIA Court”) in accordance with the LCIA Rules. Where the arbitration is to be conducted by a panel of three arbitrators, each
party shall nominate one arbitrator and the two party-nominated arbitrators shall then select the chairman of the Arbitral Tribunal. If the two party-nominated arbitrators are unable to do so within 30 days after the commencement of the arbitration
or any mutually agreed extension thereof, the chairman shall be selected by the LCIA Court in accordance with the LCIA Rules; 

(c)    The place of arbitration shall be London; 

(d)    The language of the arbitration shall be English; 

(e)    Each arbitrator shall be licensed to practice law in New York; 

(f)    Each party shall have the right to apply to any court of competent jurisdiction and/or to the Arbitral Tribunal for
an order or award of interim, provisional or conservatory measures in order to maintain the status quo or to protect its rights or property pending arbitration pursuant to this Agreement or for the purpose of compelling a party to arbitrate and
seeking temporary or preliminary relief in aid of an arbitration hereunder, and any such application shall not be deemed incompatible with, or a waiver of, the parties’ agreement to arbitrate; 

(g)    The Arbitral Tribunal shall have power to take whatever interim measures it deems necessary, including injunctive
relief, specific performance and other equitable relief, including in accordance with the provisions set forth in Section 7.14 of this Agreement; 

(h)    The award rendered by the Arbitral Tribunal shall be final and binding between the parties and not subject to
appeal or other recourse; and 
 (i)    Recognition and enforcement of any award rendered by the Arbitral Tribunal may
be sought in any court of competent jurisdiction. 
 Section 7.7    Severability. If any provision of this
Agreement is found to be invalid or unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable and to provide for the consummation of the transactions contemplated hereby on substantially
the same terms as originally set forth herein, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force and effect unless the severed provision is
essential to the rights or benefits intended by the parties. In such event, the parties shall use commercially reasonable efforts to negotiate, in good faith, a substitute, valid and enforceable provision or agreement, which most nearly effects the
parties’ intent in entering into this Agreement. 
 Section 7.8    No Third Party Beneficiaries. This
Agreement shall be binding upon and inure solely to the benefit of, and be enforceable by, only the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any
other Person any right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement. 

  
 30 

 Section 7.9    Successors and Assigns. The provisions of this
Agreement shall inure to the benefit of, and shall be binding upon, the successors and permitted assigns of the parties hereto. Except as otherwise provided herein, neither this Agreement nor any of the rights, interests, or obligations hereunder
shall be assigned by any party hereto (whether by operation of law or otherwise) without the prior written consent of the other parties. 

Section 7.10    Construction. Each of the parties has participated in the drafting and negotiation of this
Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of
authorship of any of the provisions of this Agreement. 
 Section 7.11    Counterparts. This Agreement may
be executed in one or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties. A facsimile or
“PDF” signature shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original. 

Section 7.12    Aggregation of Shares. All Securities held or acquired by the Investor shall be aggregated
together for the purpose of determining the availability of any rights of the Investor under this Agreement. 

Section 7.13    Investor Rights Agreement to Control. If, and to the extent that, there are inconsistencies
between the provisions of this Agreement and those of the Company Certificates and the Company Bylaws, the terms of this Agreement shall control to the extent permissible under any applicable Law. The parties agree to take all actions necessary or
advisable, as promptly as practicable after the discovery of such inconsistency, to amend the Company Certificates and the Company Bylaws so as to eliminate such inconsistency to the extent permissible under any applicable Law. 

Section 7.14    Specific Performance. The parties hereto acknowledge and agree irreparable harm may occur for
which money damages would not be an adequate remedy in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to any
other remedies at law or in equity, the parties to this Agreement shall be entitled to injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without posting any bond or other
undertaking. 
 Section 7.15    Amendment; Waiver. Any provision of this Agreement may be amended, modified
or supplemented only by a written instrument duly executed by all the parties hereto. The observance of any provision in this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by
the written consent of the party against whom such waiver is to be effective. Any amendment or waiver effected in accordance with this Section 7.15 shall be binding upon the Company and the Investor and their

  
 31 

 
respective assigns. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this
Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter
occurring. 
 Section 7.16    Expenses. Except as expressly provided herein, each party will bear its own
costs and expenses incurred by it or on its behalf in connection with the Transaction Documents and the transactions contemplated thereby. 

Section 7.17    Public Announcements. Without limiting any other provision of this Agreement, the parties
hereto, to the extent permitted by applicable Law, will consult with each other before issuance, and provide each other the opportunity to review, comment upon and concur with, and use all reasonable efforts to agree on any press release or public
statement with respect to this Agreement and the other Transaction Documents and the transactions contemplated hereby and thereby, and will not (to the extent practicable) issue any such press release or make any such public statement prior to such
consultation and agreement, except as may be required by Law or any listing agreement with or requirement of the Nasdaq or any other applicable securities exchange, provided that the disclosing party shall, to the extent permitted by applicable Law
or any listing agreement with or requirement of the Nasdaq or any other applicable securities exchange and if reasonably practicable, inform the other parties about the disclosure to be made pursuant to such requirements prior to the disclosure.
