 WHEREAS, the Company and B. Riley Principal Investments, LLC
(“BRPI”), have entered into that certain Subordinated Term Loan and Security Agreement (the “LSA”) on the date hereof pursuant to which BRPI has made available to the Company a subordinated credit facility in the
amount of $10,000,000 (the “Debt Facility”) and, on the date hereof or as soon as practicable thereafter, the Company, certain holders of Series A Preferred and the BR Investors shall enter into a Series A Preferred Stock Secondary

WHEREAS, the Company and the Investors (who in the aggregate hold the requisite number of shares of Series Preferred required to amend
the Agreements) desire to amend, effective and contingent upon the execution of the LSA, the Agreements as provided herein. 
 NOW,
THEREFORE, in consideration of the mutual promises and covenants herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

the Rights Agreement, as a “Major Investor” under the Co-Sale Agreement, subject to the terms as provided herein and therein. 

b. Effective and contingent upon the purchase of shares of Series A Preferred by the BR Investors pursuant to the Purchase Agreement, each BR
Investor shall be added as an “Investor” under the Rights Agreement and Voting Agreement, and each BR Investor holding at least 2,500,000 shares of Series Preferred, shall be added as a “Major Investor” under the Co-Sale Agreement, subject to the terms as provided herein and therein. Effective upon its acquisition of shares of Series A Preferred by a successor BR Group member, such successor BR Group member shall be added as
an “Investor” under the Rights Agreement and Voting Agreement, and if such successor BR Group member holds at least 2,500,000 shares of Series Preferred, shall be added as a “Major Investor” under the Co-Sale Agreement, subject to the terms as provided herein and therein; the Company may require a successor BR Group member to enter into accession agreements for the Rights Agreement and Voting Agreement and, if
applicable, the Co-Sale Agreement or such other documentation as the Company and such successor BR Group member may otherwise agree.

 3. Amendment of Voting Agreement. Effective and contingent upon the execution of the LSA, the Voting

 “1.2 Election of Directors. On all matters relating
to the election of directors of the Company, the Key Holders and the Investors agree to vote all Key Holder Shares and Investor Shares held by them (or the holders thereof shall consent pursuant to an action by written consent of the holders of
capital stock of the Company) so as to elect members of the Company’s Board of Directors (the “Board”) as follows: 

(a) For so long as fifteen million (15,000,000) shares of Series Preferred remain outstanding (subject to adjustment for any

 3 

 (i) the Company’s chief executive officer (the
“CEO”), who initially shall be Bob Plaschke; 
 (ii) one director who shall be designated by a
majority in interest of the shares held by Verdoso Investments S.A. and its affiliates (“Verdoso”), Investec Investments (UK) Limited and its affiliates (“Investec”), and Waveland Venture Partners LLC and its

 (v) (A) one director who shall

conversion of BRPI’s term loan to Series A-3 Preferred, so long as BRPI holds at least 7,000,000 shares of Series A-3 Preferred issued upon conversion of
indebtedness pursuant to Section 4 of that certain Subordinated Secured Convertible Promissory Note dated as of October 23, 2017 issued by the Company to BRPI (the “BRPI Note”), who shall initially be Alan Howe; and
(B) following conversion of the BRPI Note, in the event BRPI receives less than 7,000,000 shares of Series A-3 Preferred thereupon, and for so long as BRPI continues to hold any shares of Series A-3 Preferred, one director who shall be an industry representative not affiliated with the Company or any Investor, who shall be designated by BRPI and subject to approval, which shall not be unreasonably withheld,
of the Existing Preferred Representative; 

  
 4 

 (vi) on or after November 1, 2017, one director who shall be

(“JKC”) or its affiliates, provided that JKC and its affiliates hold at least four million (4,000,000) shares of Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event). In the event that
the Company consummates an “Acquisition” as defined in Article IV Section F.4. of the Certificate, the Company shall use commercially reasonable efforts to cause the successors of the Company to (i) maintain JKC’s right to
designate a representative of JKC to the board of the surviving corporation and (ii) assume the Company’s obligations with respect to indemnification of the directors of the Company prior to such Acquisition; and 

(viii) any vote taken to remove any director elected pursuant to this Section 1.2(a), or to fill any vacancy created
by the resignation, removal or death of a director elected pursuant to this Section 1.2(a), shall also be subject to the provisions of this Section 1.2(a); provided if the minimum shareholding requirements for designation of a board
seat set forth in any of clauses (ii) through (vii) shall not at any time be met, the replacement director shall be elected by a majority vote of the Company’s Voting Preferred Stock (as defined in the Company’s Amended and Restated
Certificate of Incorporation), voting together on an “as converted basis”; provided further that each party to this Agreement agrees to vote all its Series Preferred for the nominee selected by a majority of the holders of
the Voting Preferred Stock held by the parties to this Agreement, voting together as a single class and on an as-converted basis. 

“BR Group” shall mean the (x) Investors that purchased shares of the Company’s Series A Preferred pursuant to that
certain Series A Preferred Stock Secondary Purchase Agreement (the “Purchase Agreement”) dated on or around October 26, 2017 (“BR Investors”), so long as they or their affiliates hold Series Preferred of the
Company, together (y) with any subsequent purchasers or assignees of Series Preferred of the Company (as assignee or transferee from an existing BR Investor or from another Series Preferred holder) who were introduced to the Company by BRiley
or one of its affiliates individually (as distinct from in a broad general offering) and who acquired such shares in a transaction arranged by BRiley or one of its affiliates. 

For purposes of clarity, upon written notice to the Company, BRPI and BRiley may from time to time without further action by the Company, its
stockholders or other board members, redesignate which particular board seat is occupied by each of the specific individuals whom BRiley 

  
 5 

 
or BRPI has previously designated for the board seats referred to in clauses (iii), (iv) and (v) above; provided, however, that any board member designated pursuant to
Section 1.2(a)(v)(B) shall be an industry representative (or other individual knowledgeable and experienced in the Company’s lines of business) not affiliated with the Company or any Investor and subject to approval, which shall not be
unreasonably withheld, of the Existing Preferred Representative.” 
 c. A new Section 1.10 to the Voting Agreement shall be added

Preferred Stock and/or Common Stock. Each Investor and Key Holder other than JKC and its affiliates agrees to vote or cause to be voted all Investor Shares and Key Holder Shares held by them, as applicable, from time to time and at all times, in
whatever manner as shall be necessary, to create the number of authorized shares of Series A-3 Preferred and/or Common Stock from time to time to ensure that there will be sufficient shares of Series A-3 Preferred for issuance upon conversion, in full, of the BRPI Note and Common Stock available for conversion of all of such shares of Series A-3 Preferred outstanding at
any given time. 
 d. A new Section 1.11 to the Voting Agreement shall be added to read in its entirety as follows: 

“1.11 Services Agreement. In connection with the consummation of the transactions contemplated by the Purchase Agreement, the
Company shall enter into a mutually agreeable consulting agreement with BRPI, which shall include the payment by the Company to BRPI of an annual management fee of $200,000 in accordance with the terms thereof. 

e. Section 3.5 to the Voting Agreement shall be amended and restated to read in its entirety as follows: 

“3.5 Amendment, Modification, Termination or Waiver. This Agreement may be amended, modified or terminated (or provisions of this
Agreement waived) only upon the written consent of (i) the Company and (ii) the holders of at least a majority of the outstanding shares of Voting Preferred, voting together as a single class and on an
as-converted basis, provided, however, that if such amendment, modification, termination or waiver has the effect of modifying the rights and/or obligations of the Key Holders in a manner that is
adverse to the Key Holders, then such amendment, modification, termination or waiver shall require the written consent of the holders of a majority of the Key Holder Shares held by Key Holders then providing services to the Company as officers,
employees or 

  
 6 

 
consultants; and provided further, any amendment to Section 1.2 or Section 1.9 which adversely affects the rights of Investec, Waveland Verdoso, Motorola, JKC or any of the BRiley Group
shall require the written consent of the holders of a majority of the Series Preferred held by Investec, Waveland (or its affiliates), Verdoso (or its affiliates), Motorola (or its affiliates) or JKC (or its affiliates), as the case may be, or of
BRiley (in the case of the BR Group). Any amendment, modification, termination or waiver so effected shall be binding upon the Company, each of the parties hereto and any assignee of any such party provided, however, that notwithstanding the
foregoing, for so long as fifteen million (15,000,000) shares of Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event) remain outstanding, Sections 1.2 and 1.3 shall not be amended or waived without the
written consent of the holders of a majority of the Series Preferred, Section 1.2(a)(ii) of this Agreement shall not be amended or waived without the written consent of the Existing Investors so long as the Existing Investors or their

event), Section 1.2(a)(iv) of this Agreement shall not be amended or waived without the written consent of BRiley so long as the BR Group holds, in the aggregate, at least thirty six million (36,000,000) shares of Series Preferred (subject to

thereunder, Section 1.2(a)(vi) of this Agreement shall not be amended or waived without the written consent of Motorola so long as Motorola and its affiliates hold at least seven million (7,000,000) shares of Series Preferred,
Section 1.2(a)(vii) of this Agreement shall not be amended or waived without the written consent of JKC so long as JKC and its affiliates hold at least four million (4,000,000) shares of Series Preferred and Section 1.8 of this Agreement
shall not be amended or waived without the written consent of holders of 70% of the Series Preferred, voting together as a separate class on an as-converted basis; provided, further that no

Preferred Stock as Investors by an instrument in 

  
 7 

 
writing signed by the Company and the holders of such series. Notwithstanding anything to the contrary in this Agreement, Section 3.16 shall not apply to Motorola, and this Agreement may not
be amended or terminated and the observance of any term of this Agreement may not be waived with respect to Motorola, without the written consent of Motorola if such amendment, termination or waiver would (A) effect any amendment, extension or
termination of any contractual or other relationship (other than those contemplated by this Agreement, the Amended and Restated Right of First Refusal and Co-Sale Agreement, the Amended and Restated Investor
Rights Agreement, that certain letter agreement dated August 29, 2016, between the Company and Motorola, and any other agreement between Motorola and the Company the subject matter of which is primarily the equity of the Company owned by

Agreement. Notwithstanding anything to the contrary in this Agreement, Section 3.16 shall not apply to BRiley, and this Agreement may not be amended or terminated and the observance of any term of this Agreement may not be waived with respect

matter of which is primarily the equity of the Company owned by BRiley) between BRiley or any of its affiliates, on the one hand, and the Company, any of its subsidiaries or any of its or their respective affiliates, on the other hand, or
(Y) impose on BRiley or any of its affiliates any material obligations or material liabilities not otherwise contemplated by this Agreement, or increase any material liabilities or material obligations of BRiley under this
Agreement.—Lastly, notwithstanding anything to the contrary in this Agreement, Section 3.16 shall not apply to JKC, and this Agreement may not be amended or terminated and the observance of any term of this Agreement may not be waived with
respect to JKC, without the written consent of JKC if such amendment, termination or waiver would (I) effect any amendment, extension or termination of any contractual or other relationship (other than those contemplated by

  
 8 

 
this Agreement, the Amended and Restated Right of First Refusal and Co-Sale Agreement, the Amended and Restated Investor Rights Agreement and any other
agreement between JKC and the Company the subject matter of which is primarily the equity of the Company owned by JKC) between JKC or any of its affiliates, on the one hand, and the Company, any of its subsidiaries or any of its or their respective

which, when taken together, shall constitute one and the same instrument.

 SONIM TECHNOLOGIES, INC. 

SECOND OMNIBUS AMENDMENT TO THE AMENDED

RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT 
 This Second Omnibus Amendment to the Amended and

December 12, 2016 by and between Sonim Technologies, Inc., a Delaware corporation (the “Company”) and the undersigned investors (the “Investors”). 

WHEREAS, the Company and certain of the Investors previously have entered into the Amended and Restated Voting Agreement (the
“Voting Agreement”), the Amended and Restated Right of First Refusal and Co-Sale Agreement (the “Co-Sale Agreement”), and the Amended
and Restated Investor Rights Agreement (the “Rights Agreement” and together with the Voting Agreement and Co-Sale Agreement, the “Agreements”) each dated as of
November 21, 2012 and amended by the Omnibus Amendment to the Amended and Restated Investor Rights Agreement, Amended and Restated Voting Agreement and Amended and Restated Right of First Refusal and
Co-Sale Agreement dated August 29, 2016; 
 WHEREAS, pursuant to the terms thereof, the
Company and the holders of a majority of the outstanding shares of Series A Preferred Stock (the “Series A Preferred”), Series B Preferred Stock (the “Series B Preferred”) and Series
A-1 Preferred Stock (the “Series A-1 Preferred” and together with the Series A Preferred and Series B Preferred, the “Series
Preferred”) may amend the Voting Agreement, the Co-Sale Agreement and the Rights Agreement; 

WHEREAS, the Company and NC Kenwood Corporation, a Japanese corporation (“JKC”), have entered into a Series A-2 Preferred Stock Purchase Agreement (the “Purchase Agreement”) on the date hereof pursuant to which the Company desires to sell, and JKC desires to purchase, shares of Series A-2 Preferred Stock of the Company (the “Series A-2 Preferred” and such shares of Series A-2 Preferred issuable to JKC
pursuant to the Purchase Agreement, the “JKC Securities”). A condition to JKC’s obligations under the Purchase Agreement is that the Company, JKC and the other parties hereto enter into this Amendment for the purpose of setting

 1 

 NOW, THEREFORE, in consideration of the mutual promises and covenants herein
contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 

1. Amendment of Agreements to add JKC as an “Investor” or a “Major Investor”. Effective and contingent upon the
issuance of the JKC Securities to JKC, JKC shall be added as an “Investor” under each of the Voting Agreement and the Rights Agreement and as a “Major Investor” under the Co-Sale Agreement,
subject to the terms as provided herein and therein. 
 2. Amendment of Rights Agreement. The Rights Agreement is hereby amended so

person to the public either pursuant to a registration statement or Rule 144 promulgated under the Securities Act, (ii) sold in a private transaction in which the transferor’s rights under Section 2.10 of this Agreement are not
assigned or (iii) held by a Holder (together with its affiliates) if, as reflected on the Company’s list of stockholders, such Holder (together with its affiliates) holds less than 1% of the Company’s outstanding Common Stock
(treating all outstanding shares of Preferred Stock on an as converted basis), the Company has completed its Initial Offering and all shares of Common Stock of the Company issuable or issued upon conversion of the Shares held by and issuable to such

A-1 and Series A Preferred Stock and Warrant Purchase Agreement and other convertible securities outstanding on the first date upon which the Company issues shares of Series

officers or directors of, or consultants or advisors to, the Company or any subsidiary pursuant to stock purchase or stock option plans or other arrangements that are approved by the Board for the primary purpose of soliciting or retaining their
services (individually, an “Equity Incentive” and collectively, “Equity Incentives”), provided, that any unvested Common Stock repurchased by the Company pursuant to the terms of a restricted stock purchase
agreement under which such Equity Incentive was issued and any Equity Incentive which expires unexercised (including, without limitation, Equity Incentives outstanding on the first date upon which the Company issues shares of Series A-2 Preferred) may again be sold or granted under this Section 4.6(a) without counting another time against the limitation set forth above.”

bank or similar financial institution, or in connection with strategic transactions involving the Company and other entities, including (i) joint ventures, manufacturing, marketing or distribution arrangements or (ii) technology license,
transfer or development arrangements, in any case the terms of which are approved by the Board of Directors;”

i. Section 5.6 shall be amended to add the following new clause (f) immediately after clause (e): 

“(f) Notwithstanding anything to the contrary in this Agreement, this Agreement may not be amended or terminated and the observance of
any term of this Agreement may not be waived with respect to JKC without the written consent of JKC if such amendment, termination or waiver would (i) effect any amendment, extension or termination of any contractual or other relationship
(other than those contemplated by this Agreement, the Amended and Restated Right of First Refusal and Co-Sale Agreement, the Amended and Restated Voting Agreement and any other agreement between JKC and the
Company the subject matter of which is primarily the equity of the Company owned by JKC) between JKC or any of its affiliates, on the one hand, and the Company, any of its subsidiaries or any of its or their respective affiliates, on the other hand,
or (ii) impose on JKC any material obligations (including any non-competition or non-solicitation covenants or obligations) or material liabilities not otherwise

Agreement (the “Agreement”) is made and entered into as of November 21, 2012, by and among SONIM TECHNOLOGIES, INC., a Delaware corporation (the “Company”), those certain holders of the Company’s Common

of even date herewith (the “Purchase Agreement”).” 
 b. Section 1.2 shall be amended and restated to read
in its entirety as follows: 
 “1.2 Election of Directors. On all matters relating to the election of directors
of the Company, the Key Holders and the Investors agree to vote all Key Holder Shares and Investor Shares held by them (or the holders thereof shall consent pursuant to an action by written consent of the holders of capital stock of the Company) so
as to elect members of the Company’s Board of Directors (the “Board”) as follows: 
 (a) For so long
as fifteen million (15,000,000) shares of Series Preferred remain outstanding (subject to adjustment for any stock split, reverse stock split or similar event), the holders of Series Preferred, voting together as a single class on an as-converted basis, shall be entitled to elect seven (7) directors of the Company which shall include: 
  

  
 5 

 (i) the Company’s chief executive officer (the
“CEO”), who initially shall be Bob Plaschke; 
 (ii) one independent director, who shall initially be

its affiliates, provided that Verdoso holds at least four million (4,000,000) shares of Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event), who initially shall be Franck Ullmann; 

(iv) one director who shall be designated by Investec Bank plc (“Investec”) or its affiliates, provided
that Investec or its affiliates holds at least four million (4,000,000) shares of Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event), who shall initially be Maurice Hochschild; 

(v) one director who shall be designated by Waveland Venture Partners LLC (“Waveland”) or its
affiliates, provided that Waveland, together with any WCP Investors (as defined in the Company’s Preferred Stock Purchase and Exchange Agreement dated November 21, 2012), if applicable, hold at least four million (4,000,000) shares of
Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event), who initially shall be Sam Irvani; 

(vi) on or after November 1, 2017, one director who shall be designated by Motorola Solutions, Inc.
(“Motorola”) or its affiliates, provided that Motorola and its affiliates hold at least seven million (7,000,000) shares of Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event); 

(vii) one director who shall be designated by JVC Kenwood Corporation (“JKC”) or its affiliates, provided
that JKC and its affiliates hold at least four million (4,000,000) shares of Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event). In the event that the Company consummates an “Acquisition” as
defined in Article IV Section F.4. of the Certificate, the Company shall use commercially reasonable efforts to cause the successors of the Company to (i) maintain JKC’s right to designate a representative of JKC to the board of the
surviving corporation and (ii) assume the Company’s obligations with respect to indemnification of the directors of the Company prior to such Acquisition; and 

  
 6 

 (viii) Any vote taken to remove any director elected pursuant to this
Section 1.2(a), or to fill any vacancy created by the resignation, removal or death of a director elected pursuant to this Section l .2(a), shall also be subject to the provisions of this Section 1.2(a).” 

c. Section 1.8 shall be amended and restated to read in its entirety as follows: 

“1.8 Change of Control. In the event that the holders of at least 70% of the outstanding shares of Series Preferred, calculated on an as-converted basis and voting as a single class on a common equivalent basis approve a transaction or series of transactions that qualify as either an “Acquisition” or “Asset Transfer” as defined
in Article IV Section F.4 of the Certificate and determine that this Section 1.8 should apply to such transaction or series of transactions (such approved Acquisition or Asset Transfer is hereinafter referred to as an “Approved Sale”
and such votes approving the Approved Sale are hereinafter referred to as the ‘Requisite Votes’), then subject to Section 1.9, the Key Holders and the Investors shall each consent to, vote for and raise no objections to the
Approved Sale, and (i) if the Approved Sale is structured as a merger or consolidation of the Company, or a sale of all or substantially all of the Company’s assets, the Key Holders and Investors shall each waive any dissenters rights,
appraisal rights or similar rights in connection with such merger, consolidation or asset sale, or (ii) if the Approved Sale is structured as a sale of the stock of the Company, the Key Holders and Investors shall each agree to sell their Key
Holder Shares and Investor Shares on the terms and conditions approved by the Requisite Votes. The Key Holders and the Investors shall each take all necessary and desirable actions approved by the Requisite Votes in connection with the consummation
of the Approved Sale, including the execution of such agreements and such instruments and other actions reasonably necessary to (i) provide the representations, warranties, indemnities, covenants, conditions,
non-compete agreements, escrow agreements and other provisions and agreements relating to such Approved Sale (provided that no Investor shall be required to agree to any operational covenants in connection
with such Approved Sale, including noncompetition and nonsolicitation covenants), and (ii) subject to the provisions contained within the Certificate, effectuate the allocation and distribution of the aggregate consideration upon the Approved
Sale.” 

  
 7 

 d. Section 1.9(e) of the Voting Agreement shall be amended and restated to read in its
entirety as follows: 
 “(e) upon the consummation of the Proposed Sale (i) each holder of each class or series of the
Company’s stock participating in such Proposed Sale will receive the same form of consideration for their shares of any class or series as is received by other holders participating in such Proposed Sale in respect of their shares of the same
class or series of stock, (ii) each holder of a series of Series Preferred participating in such Proposed Sale will receive the same amount of consideration per share of such series of Series Preferred as is received by other holders
participating in such Proposed Sale in respect of their shares of the same series in payment of the liquidation preferences payable in respect to such series of Series Preferred, (iii) each holder of Common Stock participating in such Proposed
Sale will receive the same amount of consideration per share of Common Stock as is received by other holders participating in such Proposed Sale in respect of their shares of Common Stock, and (iv) the aggregate consideration legally available
for distribution to the Company’s stockholders shall be allocated among the holders of Series Preferred and Common Stock on the basis of the relative liquidation preferences to which the holders of each respective series of Series Preferred and
the holders of Common Stock are entitled in a Deemed Liquidation Event (assuming for this purpose that the Proposed Sale is a Deemed Liquidation Event) in accordance with the Certificate; provided, however, that, notwithstanding the foregoing, if
the consideration to be paid in exchange for the Key Holder Shares or Investor Shares, as applicable, pursuant to this Section 1.9(e) includes any securities and due receipt thereof by any Key Holder or Investor would require under applicable
law (x) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities; or (y) the provision to any Key Holder or Investor of any information other than such information
as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act, the Company may cause to be paid to any such Key Holder or Investor in lieu
thereof, against surrender of the Key Holder Shares or Investor Shares, as applicable, which would have otherwise been sold by such Key Holder or Investor, an amount in cash equal to the fair value (as determined in good faith by the Company) of the
securities which such Key Holder or Investor would otherwise receive as of the date of the issuance of such securities in exchange for the Key Holder Shares or Investor Shares, as applicable; and” 

  
 8 

 e. Section 1.9(f) of the Voting Agreement shall be amended to add the following sentence at
the end of Section 1.9(f) thereof: 
 “Lastly, notwithstanding anything to the contrary in this Agreement, JKC will not be required to
comply with the terms and conditions of Section 1.8 in connection with any Proposed Sale (i) unless the only covenants or other agreements that JKC or any of its affiliates shall be required to make in connection with a Proposed Sale are
reasonable covenants regarding publicity, press releases and similar matters (and, for the avoidance of doubt, in no event shall any non-compete, non-solicit or similar
covenant or obligation be imposed on JKC or any of its affiliates), (ii) if doing so would have a disproportionately adverse effect on JKC as compared to the effect on the other holders of the Series A-2
Preferred; and (iii) if doing so would effect any amendment, extension or termination of any contractual or other relationship (other than the relationship contemplated by this Agreement, the Amended and Restated Right of First Refusal and Co-Sale Agreement, the Amended and Restated Investor Rights Agreement and any other agreement between JKC and the Company the subject matter of which is primarily the equity of the Company owned by JKC) between JKC
or any of its affiliates, on the one hand, and the Company, the acquirer or any of its or their respective affiliates, on the other hand.” 

f. Section 3.5 to the Voting Agreement shall be amended and restated to read in its entirety as follows: 

“3.5 Amendment, Modification, Termination or Waiver. This Agreement may be amended, modified or terminated (or
provisions of this Agreement waived) only upon the written consent of (i) the Company and (ii) the holders of at least a majority of the outstanding shares of Series Preferred, voting together as a single class and on an as-converted basis, provided, however, that if such amendment, modification, termination or waiver has the effect of modifying the rights and/or obligations of the Key Holders in a manner that is adverse to the Key

stockholder of any of identical representations, warranties and covenants provided by all stockholders); 
 (c) the
liability for indemnification, if any, of such Investor or Key Holder in the Proposed Sale and for the inaccuracy of any representations and warranties made by the Company in connection with such Proposed Sale, is several and not joint with any
other Person (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company), and subject to the provisions of the Certificate related to the allocation of the
escrow, is pro rata in proportion to, and does not exceed, the amount of consideration paid to such Investor or Key Holder in connection with such Proposed Sale, except with respect to claims related to fraud by such Investor or Key Holder, the
liability for which need not be limited as to such Investor or Key Holder; 
 (d) liability shall be limited to such
Investor’s or Key Holder’s applicable share (determined based on the respective proceeds payable to each stockholder in connection with such Proposed Sale in accordance with the provisions of the Certificate) of a negotiated aggregate
indemnification amount that applies equally to all stockholders but that in no event exceeds the amount of consideration otherwise payable to such Investor or Key Holder in connection with such Proposed Sale, except with respect to claims related to
fraud by such Investor or Key Holder, the liability for which need not be limited as to such Investor or Key Holder; 

 (e) upon the consummation of the Proposed Sale (i) each holder of
each class or series of the Company’s stock will receive the same form of consideration for their shares of such class or series as is received by other holders in respect of their shares of such same class or series of stock, (ii) each
holder of a series of Series Preferred will receive the same amount of consideration per share of such series of Series Preferred as is received by other holders in respect of their shares of such same series in payment of the liquidation
preferences payable in respect to such series of Series Preferred, (iii) each holder of Common Stock will receive the same amount of consideration per share of Common Stock as is received by other holders in respect of their shares of Common
Stock, and (iv) the aggregate consideration legally available for distribution to the Company’s stockholders shall be allocated among the holders of Series Preferred and Common Stock on the basis of the relative liquidation preferences to
which the holders of each respective series of Series Preferred and the holders of Common Stock are entitled in a Deemed Liquidation Event (assuming for this purpose that the Proposed Sale is a Deemed Liquidation Event) in accordance with the
Certificate; provided, however, that, notwithstanding the foregoing, if the consideration to be paid in exchange for the Key Holder Shares or Investor Shares, as applicable, pursuant to this Section 1.9(e) includes any securities and due
receipt thereof by any Key Holder or Investor would require under applicable law (x) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities; or (y) the provision
to any Key Holder or Investor of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act,
the Company may cause to be paid to any such Key Holder or Investor in lieu thereof, against surrender of the Key Holder Shares or Investor Shares, as applicable, which would have otherwise been sold by such Key Holder or Investor, an amount in cash
equal to the fair value (as determined in good faith by the Company) of the securities which such Key Holder or Investor would otherwise receive as of the date of the issuance of such securities in exchange for the Key Holder Shares or Investor
Shares, as applicable; and 
 (f) subject to clause (e) above, requiring the same form of consideration to be
available to the holders of any single class or series of capital stock, if any holders of any capital stock of the Company are given an option as to the form and amount of consideration to be 

 
received as a result of the Proposed Sale, all holders of such capital stock will be given the same option; provided, however, that nothing in this Subsection 1.9(f) shall entitle any holder to
receive any form of consideration that such holder would be ineligible to receive as a result of such holder’s failure to satisfy any condition, requirement or limitation that is generally applicable to the Company’s shareholders. 

Notwithstanding anything to the contrary in this Agreement, Motorola will not be required to comply with the terms and conditions of
Section 1.8 in connection with any Proposed Sale (i) unless the only covenants or other agreements that Motorola or any of its affiliates shall be required to make in connection with a Proposed Sale are reasonable covenants regarding
publicity, press releases and similar matters (and, for the avoidance of doubt, in no event shall any non-compete, non-solicit or similar covenant or obligation be
imposed on Motorola or any of its affiliates), (ii) if doing so would have a disproportionately adverse effect on Motorola as compared to the effect on the other holders of the Series A Preferred or Series A-1
Preferred; and (iii) if doing so would effect any amendment, extension or termination of any contractual or other relationship (other than the relationship contemplated by this Agreement, the Amended and Restated Right of First Refusal and Co-Sale Agreement, the Amended and Restated Investor Rights Agreement, that certain letter agreement dated August 29, 2016 between the Company and Motorola, and any other agreement between Motorola and the
Company the subject matter of which is primarily the equity of the Company owned by Motorola) between Motorola or any of its affiliates, on the one hand, and the Company, the acquirer or any of its or their respective affiliates, on the other
hand.” 
 f. Section 3.5 to the Voting Agreement shall be amended and restated to read in its entirety as follows: 

“3.5 Amendment, Modification, Termination or Waiver. This Agreement may be amended, modified or terminated
(or provisions of this Agreement waived) only upon the written consent of (i) the Company and (ii) the holders of at least a majority of the outstanding shares of Series Preferred, voting together as a single class and on an as-converted basis, provided, however, that if such amendment, modification, termination or waiver has the effect of modifying the rights and/or obligations of the Key Holders in a manner that is adverse to the Key
Holders, then such amendment, modification, termination or waiver shall require the written consent of the holders of a majority of the Key Holder Shares held by Key Holders then providing services to the Company as officers, employees or
consultants; and provided further, any amendment to 

 Section 1.2 or Section 1.9 which adversely affects the rights of Investec,

majority of the Series Preferred, Section 1.2(a)(iii) of this Agreement shall not be amended or waived without the written consent of Verdoso so long as Verdoso holds at least four million (4,000,000) shares of Series Preferred (subject to

Investors, hold at least four million (4,000,000) shares of Series Preferred (subject to adjustment for any stock split, reverse stock split or similar event), Section 1.2(a)(vi) of this Agreement shall not be amended or waived without the
written consent of Motorola so long as Motorola and its affiliates hold at least seven million (7,000,000) shares of Series Preferred and Section 1.8 of this Agreement shall not be amended or waived without the written consent of holders of 70%
of the Series Preferred, voting together as a separate class on an as-converted basis; provided, further that no provision of this Section 3.5 can be amended without the required percentage vote of the
beneficiary of that provision. Notwithstanding the foregoing, this Agreement may be amended to add holders of additional series of the Company’s Preferred Stock as Investors by an instrument in writing signed by the Company and the holders of
such series. Lastly, notwithstanding anything to the contrary in this Agreement, Section 3.16 shall not apply to Motorola, and this Agreement may not be amended or terminated and the observance of any term of this Agreement may not be waived
with respect to Motorola without the written consent of Motorola if such amendment, termination or waiver would (A) effect any amendment, extension or termination of any contractual or other relationship (other than those contemplated by this
Agreement, the Amended and Restated Right of First Refusal and Co-Sale Agreement, the Amended and Restated Investor Rights Agreement, that certain letter agreement dated August

 29, 2016 between the Company and Motorola, and any other agreement between Motorola and the
Company the subject matter of which is primarily the equity of the Company owned by Motorola) between Motorola or any of its affiliates, on the one hand, and the Company, any of its subsidiaries or any of its or their respective affiliates, on the
other hand, or (B) impose on Motorola any material obligations (including any non-competition or non-solicitation covenants or obligations) or material liabilities
not otherwise contemplated by this Agreement, or increase any material liabilities or material obligations of Motorola under this Agreement.” 

g. Exhibit A to the Voting Agreement shall be amended to add the New Investors as “Investors” thereunder.

(other than those contemplated by this Agreement, the Amended and Restated Voting Agreement, the Amended and Restated Investor Rights Agreement, 

 that certain letter agreement dated August 29, 2016 between the Company and Motorola,
and any other agreement between Motorola and the Company the subject matter of which is primarily the equity of the Company owned by Motorola) between Motorola or any of its affiliates, on the one hand, and the Company, any of its subsidiaries or
any of its or their respective affiliates, on the other hand, or (ii) impose on Motorola any material obligations (including any non-competition or non-solicitation

6. Except as expressly set forth herein, all other provisions of the Voting Agreement, the Rights Agreement and the Co-Sale Agreement shall remain in full force and effect. This Amendment shall be deemed incorporated into and made a part of the Voting Agreement, the Rights Agreement and the
Co-Sale Agreement, as applicable. 
 7. This Amendment and the rights and obligations of the parties
hereunder shall inure to the benefit of, and be binding upon, their respective successors, assigns and legal representatives.

 Securities in such registration shall be conditioned upon such Holder’s participation. in such
underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement

the Initiating Holders). Notwithstanding any other provision of this Section 2.2 or Section 2.4, if the underwriter advises the Company that marketing factors require a limitation of the number of securities to be underwritten (including
Registrable Securities) then the Company shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be allocated to the Holders
of such Registrable Securities on a pro rata basis based on the number of Registrable Securities held by all such Holders (including the Initiating Holders); provided, however, that the number of shares of Registrable Securities to be
included in such underwriting and registration shall not be reduced unless all other securities of the Company are first entirely excluded from the underwriting and registration. Any Registrable Securities excluded or withdrawn from such
underwriting shall be withdrawn from the registration. 
 (c) The Company shall not be required to effect a registration pursuant to
this Section 2.2: 
 (i) prior to the earlier of (A) the third anniversary of the date of this Agreement or (B) one
hundred eighty (180) days following the effective date of the registration statement pertaining to the Initial Offering; 

(ii) after the Company has effected two (2) registrations pursuant to this Section 2.2, and such registrations have been
declared or ordered effective; 
 (iii) during the period starting with the date of filing of, and ending on the date one
hundred eighty (180) days following the effective date of the registration statement pertaining to a public offering, other than pursuant to a Special Registration Statement; provided that the Company makes reasonable good faith efforts
to cause such registration statement to become effective; 
 (iv) if within thirty (30) days of receipt of a written
request from Initiating Holders pursuant to Section 2.2(a), the Company gives notice to the Holders of the Company’s intention to file a registration statement for a public offering, other than pursuant to a Special Registration Statement,
within ninety (90) days; 
 (v) if the Company shall furnish to Holders requesting a registration statement pursuant to this
Section 2.2, a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration
statement to be effected at such time, in which event the Company shall have the right to defer such filing for a period of 

  
 6 

 
not more than one hundred twenty (120) days after receipt of the request of the Initiating Holders; provided that such right to delay a request shall be exercised by the Company not
more than once in any twelve (12) month period and provided further that the Company shall not register any securities for the account of itself or any other stockholder during such 120 day period, other than a Special Registration Statement;
 
 (vi) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately
registered on Form S-3 pursuant to a request made pursuant to Section 2.4 below; or 

(vii) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a
general consent to service of process in effecting such registration, qualification or compliance. 
 2.3 Piggyback Registrations. The
Company shall notify all Holders of Registrable Securities in writing at least fifteen (15) days prior to the filing of any registration statement under the Securities Act for purposes of a public offering of securities of the Company
(including, but not limited to, registration statements relating to secondary offerings of securities of the Company and registration statements effected pursuant to Section 2.2 or by the Company for stockholders other than the Holders, but
excluding Special Registration Statements) and will afford each such Holder an opportunity to include in such registration statement all or part of such Registrable Securities held by such Holder. Each Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by it shall, within fifteen (15) days after the above-described notice from the Company, so notify the Company in writing. Upon the written request of each Holder, the
Company shall, subject to the provisions of Section 2.2(c), use commercially reasonable efforts to cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered. Such
notice shall state the intended method of disposition of the Registrable Securities by such Holder. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder 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, all upon the terms and
conditions set forth herein. 
 (a) Underwriting. If the registration statement under which the Company gives notice under this
Section 2.3 is for an underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration pursuant to this Section 2.3 shall be conditioned
upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through
such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Agreement, if the underwriter determines
in good faith that marketing factors require a limitation of the number of shares to be 

  
 7 

 
underwritten, the number of shares that may be included in the underwriting shall be allocated, first, to the Company; second, to the Holders on a pro rata basis based on the total number
of Registrable Securities held by the Holders; and third, to any stockholder of the Company (other than a Holder) on a pro rata basis; provided, however, that no such reduction shall reduce the amount of securities of the selling Holders
included in the registration below twenty-five percent (25%) of the total amount of securities included in such registration, unless such offering is the Initial Offering and such registration does not include shares of any other selling
stockholders, in which event any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding clause. In no event will shares of any other selling stockholder be included in such registration that
would reduce the number of shares which may be included by Holders without the written consent of Holders of not less than a majority of the Registrable Securities proposed to be sold in the offering. If any Holder disapproves of the terms of any
such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter, delivered at least .ten (10) business days prior to the effective date of the registration statement. Any Registrable
Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder which is a partnership or corporation, the partners, retired partners and stockholders of such Holder, or the
estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing person shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such
“Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence. 

(b) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under
this Section 2.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by the Company in
accordance with Section 2.5 hereof. 
 2.4 Form S-3. Registration. In case the Company
shall receive from the Initiating Holders a written request or requests that the Company effect a registration on Form S-3 (or any successor to Form S-3) or any similar
short-form registration statement and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Initiating Holders, the Company will: 

(a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other
Holders of Registrable Securities; and 
 (b) as soon as practicable, use commercially reasonable efforts to effect such
registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Initiating Holders’ Registrable Securities as are specified in such
request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the
Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 2.4: 

  
 8 

 (i) if Form S-3 is not available for such
offering by the Initiating Holders; or 
 (ii) if the Holders, together with the holders of any other securities of the
Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than three million dollars ($3,000,000); or 

(iii) if within thirty (30) days of receipt of a written request from the Initiating Holders pursuant to this Section 2.4,
the Company gives notice to such Holders of the Company’s intention to make a public offering within ninety (90) days, other than pursuant to a Special Registration Statement; 

(iv) if the Company shall furnish to the Initiating Holders a certificate signed by the Chairman of the Board of Directors
of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such Form S-3 registration to be
effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than one hundred twenty (120) days after receipt
of the request of the Initiating Holders under this Section 2.4; provided, that such right to delay a request shall be exercised by the Company not more than once in any twelve (12) month period; and provided, further, that
the Company shall not register any securities for the account of itself or any other stockholder during such one hundred twenty (120) day period, other than a Special Registration Statement; or 

(v) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration, qualification or compliance. 
 (c) Subject to the foregoing, the
Company shall file a Form S-3 registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the requests of the
Initiating Holders. Registrations effected pursuant to this Section 2.4 shall not be counted as demands for registration or registrations effected pursuant to Section 2.2. 

2.5 Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any
registration, qualification or compliance pursuant to Section 2.2 or any registration under Section 2.3 or Section 2.4 herein shall be borne by the Company including the reasonable expenses of one special counsel to selling
stockholders. All Selling Expenses incurred in connection with any registrations hereunder shall be borne by the holders of the securities so registered pro rata on the basis of the number of 

  
 9 

 
shares so registered. The Company shall not, however, be required to pay for expenses of any registration proceeding begun pursuant to Section 2.2 or 2.4, the request of which has been
subsequently withdrawn by the Initiating Holders unless (a) the withdrawal is based upon material adverse information concerning the Company of which the Initiating Holders were not aware at the time of such request or (b) the Holders of a
majority of Registrable Securities agree to forfeit their right to one requested registration pursuant to Section 2.2 or Section 2.4, as applicable, in which event such right shall be forfeited by all Holders. If the Holders are required
to pay the Registration Expenses, such expenses shall be borne by the holders of securities (including Registrable Securities) requesting such registration in proportion to the number of shares for which registration was requested. If the Company is
required to pay the Registration Expenses of a withdrawn offering pursuant to clause (a) above, then the Holders shall not forfeit their rights pursuant to Section 2.2 or Section 2.4 to a demand registration. 

2.6 Obligations of the Company. Whenever required to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible: 
 (a) prepare and file with the SEC a registration statement with respect to such
Registrable Securities and use all commercially reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to ninety (90) days or, if earlier, until the Holder or Holders have completed the distribution related thereto; provided, however, that at any time, upon written notice to the participating Holders and
for a period not to exceed sixty (60) days thereafter (the “Suspension Period”), the Company may delay the filing or effectiveness of any registration statement or suspend the use or effectiveness of any registration
statement (and the Initiating Holders hereby agree not to offer or sell any Registrable Securities pursuant to such registration statement during the Suspension Period) if the Company reasonably believes, in the good faith judgment of the Board,
that the Company may, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose any corporate development the disclosure of which could reasonably be expected to have a material adverse
effect upon the Company, its stockholders, a potentially significant transaction or event involving the Company, or any negotiations, discussions, or proposals directly relating thereto. No more than two (2) such Suspension Periods shall occur
in any twelve (12) month period. In the event that the Company shall exercise its right to delay or suspend the filing or effectiveness of a registration hereunder, the applicable time period during which the registration statement is to remain
effective shall be extended by a period of time equal to the duration of the Suspension Period. The Company may extend the Suspension Period for an additional consecutive sixty (60) days with the consent of the holders of a majority of the
Registrable Securities registered under the applicable registration statement, which consent shall not be unreasonably withheld. If so directed by the Company, all Holders registering shares under such registration statement shall use their best
efforts to deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holders’ possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such
notice. 

  
 10 

 (b) Prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration
statement for the period set forth in subsection (a) above. 
 (c) Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 

(d) Use commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions. 
 (e) In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations
under such an agreement. 
 (f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a
prospectus relating thereto is required to be delivered under the Securities Act 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. The Company will use commercially reasonable efforts to amend or
supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or omit 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. 
 (g) Use commercially reasonable efforts to furnish, on the date that such Registrable
Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and (ii) a letter, dated as of such date, from the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to underwritten in an underwritters public offering addressed to the underwriters. 

  
 11 

 2.7 Termination of Registration Rights. All registration rights granted under this
Section 2 shall terminate and be of no further force and effect on the first to occur of (i) five (5) years after the date of the Company’s Initial Offering or (ii) as to any Holder, at such time as such Holder is able to offer
for sale all of its Registrable Securities within a three (3) month period pursuant to Rule 144 of the Securities Act and such Holder owns less than one percent (1 %) of the Registrable Securities. 

2.8 Delay of Registration; Furnishing Information. 

(a) No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result
of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 
 (b) It shall be a
condition precedent to the obligations of the Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them
and the intended method of disposition of such securities as shall be required to effect the registration of their Registrable Securities. 

2.9 Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.2, 2.3 or 2.4:

 (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers and
directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, 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 (collectively a “Violation”) by the Company: (i) any untrue statement or alleged untrue statement of a material fact contained in such
registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein 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 the Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the offering covered by such registration statement; and the Company will reimburse each such Holder, partner, member, officer,
director, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, as such expenses are incurred (upon delivery of
a bona fide invoice or other documentation indicating the accrual of such expenses); provided however, that the indemnity agreement contained in this Section 2.9(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, nor shall the Company be liable in any such case for any such loss,

  
 12 

 
claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly
for use in connection with such registration by such Holder, partner, member, officer, director, underwriter or controlling person of such Holder. 

(b) To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to
which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the Securities Act, any
underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors or officers or any person who controls such Holder, against any losses, claims, damages or liabilities
(joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any of the following statements: (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein 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 the Securities Act ( collectively, a
“Holder Violation”), in each case to the extent (and only to the extent) that such Holder Violation occurs in reliance upon and in conformity with written information furnished by such Holder under an instrument duly executed
by such Holder and stated to be specifically for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person,
underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such
a Holder Violation; provided, however, that the indemnity agreement contained in this Section 2.9(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 Holder, which consent shall not be unreasonably withheld; provided further, that in no event shall any indemnity under this Section 2.9 exceed the net proceeds from the offering received by such Holder. 

(c) Promptly after receipt by an indemnified party under this Section 2.9 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 this Section 2.9, 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 the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the
parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and 

  
 13 

 
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. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action,
if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.9, but the omission so 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 2.9. 
 (d) If the
indemnification provided for in this Section 2.9 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in
lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified paiiy as a result of such loss, claim, damage or liability in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law 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 paiiy or by the indemnified paiiy and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission; provided, that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder. 

(e) The obligations of the Company and Holders under this Section 2.9 shall survive completion of any offering of Registrable
Securities in a registration statement and the termination of this Agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified party of a release from all liability in respect to such claim or litigation. 

2.10 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this
Section 2 may be assigned by a Holder to a transferee or assignee of Registrable Securities that (a) is a subsidiary, parent, general partner, limited partner, retired partner, member or retired member, affiliate or stockholder of a
Holder, (b) is a Holder’s family member or trust for the benefit of an individual Holder, or (c) acquires at least 10% of the total Registrable Securities or at least fifty percent (50%) of the Registrable Securities held by such
Holder; or (d) is an entity affiliated by common management or control (or other related entity)· with such Holder; provided, however, (i) the transferor shall, within ten (10) days after such transfer, furnish to the
Company 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 (ii) such transferee shall agree to be subject to all restrictions set forth
in this Agreement. 

  
 14 

 2.11 Amendment of Registration Rights. Any provision of this Section 2 may
be amended and the observance thereof may be waived ( either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Holders of a majority of the Registrable Securities
then outstanding. Any amendment or waiver effected in accordance with this Section 2.11 shall be binding upon each Holder and the Company. By acceptance of any benefits under this Section 2, Holders of Registrable Securities hereby agree
to be bound by the provisions hereunder. · 
 2.12 Limitation on Subsequent Registration Rights. Other than as provided in
Section 5.11, after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder
of any securities of the Company that would grant such holder registration rights on a parity with or senior to those granted to the Holders hereunder, other than the right to a Special Registration Statement. 

2.13 “Market Stand-Off’ Agreement. Each Holder hereby agrees that
such Holder shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held
by such Holder (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the
effective date of a registration statement of the Company filed under the Securities Act; provided that: 
 (i) such agreement
shall apply only to the Company’s Initial Offering; and 
 (ii) all officers and directors of the Company and holders of at
least one percent (1 %) of the Company’s voting securities enter into similar agreements. 
 2.14 Agreement to Furnish Information.
Each Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter that are consistent with the Holder’s obligations under Section 2.13 or that are necessary to give further
effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, each Holder shall provide, within ten (10) days of such request, such information as may be
reasonably required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in
Section 2.13 and this Section 2.14 shall not apply to a Special Registration Statement. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction
until the end of 

  
 15 

 
said one hundred eighty (180) day period. Each Holder agrees that any transferee of any shares of Registrable Securities shall be bound by Sections 2.13 and 2.14. The underwriters of the
Company’s stock are intended third party beneficiaries of Sections 2.13 and 2.14 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 

2.15 Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which
may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its best efforts to: 

(a) Make and keep public information available, as those terms are understood and defined in SEC Rule 144 or any similar or analogous
rule promulgated under the Securities Act, at all times after the effective. date of the first registration filed by the Company for an offering of its securities to the general public; 

(b) File with the SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and 

(c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request: a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); a copy of the most recent annual or quarterly
report of the Company filed with the Commission; and such other reports and documents as a Holder may reasonably request in connection with availing itself of any rule or regulation of the SEC allowing it to sell any such securities without
registration.

property furnished to it that the Company identifies as being confidential or proprietary (so long as such information is not in the public domain), except that such Investor may disclose such proprietary or confidential information (i) to any
partner, subsidiary or parent of such Investor for the sole purpose of evaluating its investment in the Company, to an Investor’s employees, counsel, accountants or other professional advisors, or to any other Investor entitled to receive such
information; (ii) at such time as it enters the public domain through not fault of such Investor; (iii) that is communicated to it free of any obligation of confidentiality; (iv) that is developed by Investor or its agents

jurisdiction process or pursuant to any direction, request or requirement 

  
 17 

 
(whether or not having the force of law but if not having the force of law being of a type with which institutional investors in the relevant jurisdiction are accustomed to comply) to any
self-regulating organization: or any governmental, fiscal, monetary or other authority; or (vi) to the extent that an Investor is required to disclose information for the sole purposes of protecting such Investor’s rights or interest with
respect to the Company, whether under this Agreement or otherwise; provided, however, that nothing contained herein shall be deemed to limit an Investor that is a venture capital or other private equity firm from disclosing the Company’s
confidential information to its partners, limited partners, affiliates, investors, to any employee of its affiliates, or to any other holder of the Company’s stock. 

(b) The Company and each Investor hereby acknowledge that some or all of the Investors are professional investment funds, and as such
invest in numerous portfolio companies, some of which may be competitive with the Company’s business. No Investor shall be liable to the Company or to any other Investor for any claim arising out of, or based upon, (i) the investment by
Investor in any entity competitive to the Company, or (ii) actions taken by any partner, officer or other representative of any Investor to assist any such competitive company, whether or not such action was taken as a board member of such
competitive company, or otherwise.

solely for issuance and delivery upon the conversion of the preferred Stock, all Common Stock issuable from time to time upon such conversion.

shares of stock held by such person. 
 3.6 Key Person Insurance. Subject to the approval of the Board of Directors, the Company will
use its best efforts to obtain and maintain in full force and effect term life insurance on the lives of one or more of the Company’s executive officers as determined by the Board of Directors, naming the Company as beneficiary, in an amount of

3.9 Assignment of Right of First Refusal. In the event the Company elects not to exercise any right of first refusal or right of first
offer the Company may have on a proposed transfer of any of the Company’s outstanding capital stock pursuant to the Company’s charter documents, the Company shall, upon authorization of the Board of Directors and to the extent it may do
so, assign such right of first refusal or right of first offer to each Major Investor. In the event of such assignment, each Major Investor shall have a right to purchase its pro rata portion of the capital stock proposed to be transferred.
Each Major Investor’s pro rata portion shall be equal to the product obtained by multiplying (i) the aggregate number of shares proposed to be transferred by (ii) a fraction, the numerator of which is the number of shares of capital
stock of the Company held by such Major Investor at the time of the proposed transfer and the denominator of which is the total number of shares owned by all Major Investors at the time of such proposed transfer. If not all of the Investors elect to
purchase their pro rata share of the · capital stock to be transferred, then those Investors who do so elect to purchase shall have the right to acquire their pro rata share of such unsubscribed shares based upon the number of
shares of Common Stock (including shares of Common Stock issuable or issued upon conversion of the Shares) held by the Investors who exercised their rights under this Section 3.9. In addition, to the extent that this Section 3.9 is in
conflict with the provisions of that certain Amended and Restated Right of First Refusal and Co-Sale Agreement of even date herewith (the “Co-Sale
Agreement”), the provisions in the Co-Sale Agreement shall control. 
 3.10
Directors’ Liability and Indemnification; Director and Officer Liability Insurance. The Company’s Certificate of Incorporation and Bylaws shall provide (a) for elimination of the liability of directors to the maximum extent
permitted by law and (b) for indemnification of directors for acts on behalf of the Company to the maximum extent permitted by law. The Company shall enter into indemnification agreements with each of its directors substantially in a form
approved by the Company’s counsel. In addition, unless the Board of Directors of the Company determines to the contrary, the Company will maintain ‘in full force and effect director and officer liability insurance in the minimum amount of
one million dollars ($1,000,000), and shall pay all premiums due on such policy as they become due. The Company shall not make any material alteration to the terms of, or the coverage provided by, such policy without the unanimous approval of the
Board. 
 3.11 Issuance of Series A Preferred and Series B Preferred. The Company shall not make any issuance of Series A Preferred
and Series B Preferred other than pursuant to the Purchase Agreement and other convertible securities outstanding on the date hereof (including for purposes of clarity the Warrant to Purchase Series B Preferred Stock held by Guinness
Mahon & Co. Limited, an affiliate of Investec Bank plc (“Investec”), and the Warrant to Purchase Series B Preferred Stock held by Verdoso Investments S.A.) unless approved by the holders of a majority of the
outstanding Series Preferred, calculated on an as-converted basis. 

  
 19 

 3.12 Compliance with Laws Covenant. the Company shall continue to comply with
applicable statutes, rules and regulations, including those relating to (a) the environment or occupational health and safety, and (b) equal employment opportunity and other laws related to employment, including, but not limited to, the
health and safety of such employees and any labor rights of such employees. The Company shall notify the Major Investors promptly if the Company (or any of its subsidiaries) shall be in material violation of any applicable statutes, rules or
regulations. 
 3.13 Visitation Rights. So long as (i) Investec or an affiliate thereof holds at least 4,000,000 shares of Series
preferred (subject to adjustment for any stock split, reverse stock split or similar event) and (ii) Investec does not have a designee serving as a member of the Board of Directors of the Company pursuant to Section 1.2(a)(iv) of the
Amended and Restated Voting Agreement among the Company and certain of its investors of even date herewith, the Company shall allow one representative designated by Investec to attend all meetings of the Company’s Board of Directors in a
nonvoting capacity, and, in connection therewith, the Company shall give such representative copies of all notices, minutes, consents, and other materials, financial or otherwise, which the Company provides to its Board of Directors; provided,
however, that the Company reserves the right to exclude such representative from access to any material or meeting or portion thereof if the Company believes that such exclusion is reasonably necessary to preserve the attorney-client privilege,
to protect highly confidential information, or for other similar reasons. The decision of the Board of Directors of the Company with respect to the privileged or confidential nature of such information shall be final and binding. 

3.14 Series B Preferred. For so long as any holder of Series B preferred owns greater than 22.5% of the outstanding capital stock of the
Company, on a fully diluted, as converted to common stock basis (each, a “221⁄2 Percent Holder”), and except as otherwise provided by the
terms set forth in the Company’s Amended and Restated Certificate of Incorporation, neither the rights, preferences, privileges and restrictions of the Series B Preferred, nor the definitions set forth in Sections 2.2 and 2.13 of the Purchase
Agreement, will be amended in an adverse manner without the consent of each 221⁄2 Percent Holder. 

3.15 Termination of Covenants. All covenants of the Company contained in Section 3 of this Agreement (other than the provisions of
Section 3.3) shall expire and terminate as to each Investor upon the effective date of the registration statement pertaining to the Qualified Initial Offering or upon the closing of an Acquisition or Asset Transfer. For purposes of this
Agreement, “Acquisition” and “Asset Transfer” shall have the meanings given them in the Company’s Amended and Restated Certificate of Incorporation. 

SECTION 4. RIGHTS OF FIRST REFUSAL. 

4.1 Subsequent Offerings. Subject to applicable securities laws, each Major Investor shall have a right of first refusal to purchase its
pro rata share of all Equity Securities, as defined below, that the Company may, from time to time, propose to sell and issue after the date of this Agreement, other than the Equity Securities excluded by Section 4. 7 hereof. Each 

  
 20 

 Major Investor’s pro rata share is equal to the ratio of (a) the number of shares of the
Company’s Common Stock (including all shares of Common Stock issuable or issued upon conversion of the Shares or the conversion or exercise of any other outstanding convertible or exercisable securities of the Company) which such Major Investor
is deemed to be a holder immediately prior to the issuance of such Equity Securities to (b) the total number of shares of the Company’s outstanding Common Stock (including all shares of Common Stock issuable or issued upon conversion of the
Shares or upon the conversion or exercise of any other outstanding convertible or exercisable securities) immediately prior to the issuance of the Equity Securities. The term “Equity Securities” shall mean (i) any Common Stock,
Preferred Stock or other security of the Company, (ii) any security convertible into or exercisable or exchangeable for, with or without consideration, any Common Stock, Preferred Stock or other security (including any option to purchase such a
convertible security), (iii) any security carrying any warrant or right to subscribe to or purchase any Common Stock, Preferred Stock or other security or (iv) any such warrant or right. 

4.2 Exercise of Rights. If the Company proposes to issue any Equity Securities, it shall give each Major Investor written notice of its
intention, describing the Equity Securities, the price and the terms and conditions upon which the Company proposes to issue the same. Each Major Investor shall have twenty-one (21) days from the giving
of such notice to agree to purchase its pro rata share of the Equity Securities for the price and upon the terms and conditions specified in the notice by giving written notice to the Company and stating therein the quantity of Equity
Securities to be purchased. Notwithstanding the foregoing, the Company shall not be required to offer or sell such Equity Securities to any Major Investor who would cause the Company to be in violation of applicable federal securities laws by virtue
of such offer or sale. 
 4.3 Issuance of Equity Securities to Other Persons. If not all of the Major Investors elect to purchase
their pro rata share of the Equity Securities, then the Company shall promptly notify in writing the Major Investors who do so elect and shall offer such Major Investors the right to acquire such unsubscribed shares on a pro rata basis based
upon the number of shares of Common Stock (including all shares of Common Stock issuable or issued upon conversion of the Shares or the conversion or exercise of any other outstanding convertible or exercisable securities of the Company) held by the
Major Investors who exercised their full rights under Section 4.2. The Major Investors shall have five (5) days after receipt of such notice to notify the Company of its election to purchase all or a portion thereof of the unsubscribed
shares. If the Major Investors fail to exercise in full the rights of first refusal, the Company shall have ninety (90) days thereafter to sell the Equity Securities in respect of which the Major Investor’s rights were not exercised, at a
price and upon general terms and conditions no more favorable to the purchasers thereof than specified in the Company’s notice to the Major Investors pursuant to Section 4.2 hereof. If the Company has not sold such Equity Securities within
ninety (90) days of the notice provided pursuant to Section 4.2, the Company shall not thereafter issue or sell any Equity Securities, without first offering such securities to the Major Investors in the manner provided above. 

 

  
 21 

 4.4 Termination ,and Waiver of Rights of First Refusal. The rights of first refusal
established by this Section 4 shall not apply to, and shall terminate upon the effective date of the registration statement pertaining to the Company’s Qualified Initial Offering, or upon the closing of an Acquisition or Asset Transfer.
The rights of first refusal established by this Section 4 may be amended, or any provision waived as permitted by Section 5.6. 

4.5 Transfer of Rights of First Refusal. The rights of first refusal of each Major Investor under this Section 4 may be
transferred to the same parties, subject to the same restrictions as any transfer of registration tights pursuant to Section 2.1 O(a), (b) or ( d), and to any other transferee if such transferee has purchased and holds a sufficient number of
shares of Series 4 Preferred to be deemed a Major Investor. 
 4.6 Excluded Securities. The rights of first refusal established by
this Section 4 shall have no application to any of the following Equity Securities: 
 (a) up to 25,000,000 shares of Common
Stock (the “Base Option Pool”) that is approved by the Company’s Board of Directors, issued after the original issue date of the Series A Preferred pursuant to such options, warrants or other rights to employees,
officers or directors of, or consultants or advisors to, the Company or any subsidiary pursuant to stock purchase or stock option plans or other arrangements that are approved by the Board for the primary purpose of soliciting or retaining their
services (individually, an “Equity Incentive” and collectively, “Equity Incentives”); provided further, that for purposes of the Base Option Pool any unvested Common Stock repurchased by the Company
pursuant to the terms of a restricted stock purchase agreement under which such Equity Incentive was issued and any Equity Incentive which expires unexercised (including, without limitation, Equity Incentives outstanding on the date hereof) may
again be sold or granted under this Section 4.7(a) without counting another time against the limitations set forth above. 
 (b)
stock issued or issuable pursuant to any rights or agreements, options, warrants or convertible securities outstanding as of the date of this Agreement; and stock issued pursuant .to any such rights or agreements granted after the date of this
Agreement, so long as the rights of first refusal established by this Section 4 were complied with or were inapplicable pursuant to any provision of this Section 4.7 with respect to the initial sale or grant by the Company of such rights
or agreements;

issued upon conversion thereof) that are outstanding on the date hereof; and

that is 120 days following end of the Company’s most recent fiscal year (or, if such date is not a Business Day, the next date that is a Business Day). In any case where the Additional Filing Deadline is extended pursuant to the foregoing
provisos, then the Additional Filing Deadline, as so extended, shall be deemed the Additional Filing Deadline for all purposes of this Agreement.

Complete Form 10-K for the preceding fiscal year by such deadline, then such deadline shall be extended until the Business Day following date on which the Complete Form
10-K for such preceding fiscal year is filed with the Commission; provided further, however, that such deadline shall not be extended beyond the date that is 120 days following the end of the
Company’s most recent fiscal year (or, if such date is not a Business Day, the next date that is a Business Day). In any case where the Additional Effectiveness Deadline is extended pursuant to the foregoing provisos, then the Additional
Effectiveness Deadline, as so extended, shall be deemed the Additional Effectiveness Deadline for all purposes of this Agreement.

Subsidiaries own or possess all material patents, trademarks, service marks, trade names, copyrights, trade secrets, information, proprietary rights and processes necessary for their business as now conducted, and as proposed to be conducted,
without any known conflict with, or known infringement of, the rights of others. All licenses, agreements and arrangements relating to the patents, trademarks, service marks, trade names, copyrights and other proprietary rights of the Company and
its Subsidiaries have been entered into in the ordinary course of business, are in full force and effect and no notice has been given on either side to terminate any of them and no amendment made or accepted to their terms since they were first
entered into; and, to the Company’s knowledge, the material obligations of all parties under each of the same have been fully complied with and no known disputes exist or are anticipated with respect to any of such agreements. Other than as set
forth in the immediately preceding sentence, there are no outstanding options, licenses or agreements of any kind relating to the patents, trademarks, service marks, trade names, copyrights and other proprietary rights of the Company and its
Subsidiaries, nor is the Company or any of its Subsidiaries bound by or a party to any options, licenses or agreements of any kind with respect to the patents, trademarks, service marks, trade names, copyrights, trade secrets, licenses, information,
proprietary rights and processes of any other person or entity, other than such licenses or agreements arising from the purchase of “off the shelf” or standard products. Except as set forth in the Disclosure Schedule, neither the Company
nor any of its Subsidiaries has received any communications alleging, nor is the Company aware of any basis for such allegation, that the Company or any of its Subsidiaries has violated or, by conducting its business as proposed, would violate any
of the patents, trademarks, service marks, trade names, copyrights or trade secrets or other proprietary rights of any other person or entity. The Company is not aware that any of the employees of the Company or any of its Subsidiaries are obligated
under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would interfere with the use of such employee’s best
efforts to promote the interests of the Company and its Subsidiaries that would conflict with the business of the Company and its Subsidiaries as proposed to be conducted. Neither the execution nor delivery of the Transaction Documents, nor the
carrying on of the Company’s or its Subsidiaries’ business by the employees of the Company or the Subsidiaries, nor the conduct of the Company or the Subsidiaries’ business as now conducted and as proposed to be conducted, will, to
the Company’s knowledge, conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument under which any of such employees is now obligated. The Company does not
believe it is or will be necessary to use any inventions of any of the Company’s or its Subsidiaries’ employees (or persons they currently intend to hire) made prior to their employment by the Company or its Subsidiaries, except for
inventions, trade secrets or proprietary information that have been assigned to the Company or its Subsidiaries. The Company has taken reasonable measures to protect its material patents, trademarks, service marks, trade names, copyrights, trade
secrets, and other proprietary rights including those filings required for the registration or certification of the foregoing. The Disclosure Schedule contains a complete list of the Company’s patents, trademarks, copyrights and domain names

payments to any of its employees, consultants, or independent contractors for any wages, salaries, commissions, bonuses, or other direct compensation for any service performed for it or amounts required to be reimbursed to such employees,
consultants or independent contractors. The Company has complied in all material respects with all applicable state and federal equal employment opportunity laws and with other laws related to employment, including those related to wages, hours,
worker classification and collective bargaining. The Company has withheld and paid to the appropriate governmental entity or is holding for payment not yet due to such governmental entity all amounts required to be withheld from employees of the
Company and is not liable for any arrears of wages, taxes, penalties or other sums for failure to comply with any of the foregoing. 
 (c)
The Company is not aware that any officer, Key Employee or group of employees of the Company or any of its Subsidiaries intends to terminate his, her or their employment with the Company or any of its Subsidiaries, nor does the Company or any of its
Subsidiaries have a present intention to terminate the employment of any officer, Key Employee or group of employees of the Company or any of its Subsidiaries. The employment of each employee of the Company is terminable at the will of the Company
in compliance with all applicable state and federal laws.     
 (d) To the Company’s knowledge, no employee of the
Company or any of its Subsidiaries, nor any consultant with whom the Company or any of its Subsidiaries has contracted, is in violation of any term of any employment contract, proprietary information agreement or any other agreement relating to the
right of any such individual to be employed by, or to contract with, the Company or such Subsidiary; and to the Company’s knowledge the continued employment by the Company and each of its Subsidiaries of its present employees, and the
performance of the Company’s and each of its Subsidiaries’ contracts with its independent contractors, will not result in any such violation. Neither the Company nor any of its Subsidiaries has received any notice alleging that any such
violation has occurred. No employee of the Company or any of its Subsidiaries has been granted the right to continued employment by the Company or such Subsidiary or to any material compensation following termination of employment with the Company
or such Subsidiary.     
 (e) Each employee, former employee and consultant of the Company and each of its Subsidiaries
has executed and delivered to the Company or such Subsidiary the appropriate form of Confidential Information and Invention Assignment Agreement as provided to counsel to the Purchasers. The Company is not aware that any employee, former employee or
consultant of the Company or any of its Subsidiaries is in violation thereof.     
 (f) Each former Key Employee whose
employment was terminated by the Company in the past three years has entered into an agreement with the Company providing for the full release of any claims against the Company or any related party arising out of such employment. 

(g) The Disclosure Schedule sets forth each employee benefit plan maintained, established or sponsored by the Company, or which the Company
participates in or contributes to, which is subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). The Company has made all required contributions and has no liability to any such employee benefit
plan, other than liability for health plan continuation coverage described in Part 6 of Title I(B) of ERISA, and has complied in all material respects with all applicable laws for any such employee benefit plan. 

 (h) To the Company’s knowledge, none of the Key Employees or directors of the Company
has been (a) subject to voluntary or involuntary petition under the federal bankruptcy laws or any state insolvency law or the appointment of a receiver, fiscal agent or similar officer by a court for his or her business or property;
(b) convicted in a criminal proceeding or named as a subject of a pending criminal proceeding (excluding traffic violations and other minor offenses); (c) subject to any order, judgment or decree (not subsequently reversed, suspended, or
vacated) of any court of competent jurisdiction permanently or temporarily enjoining him or her from engaging, or otherwise imposing limits or conditions on his or her engagement in any securities, investment advisory, banking, insurance, or other
type of business or acting as an officer or director of a public company; or (d) found by a court of competent jurisdiction in a civil action or by the Securities and Exchange Commission or the Commodity Futures Trading Commission to have
violated any federal or state securities, commodities, or unfair trade practices law, which such judgment or finding has not been subsequently reversed, suspended, or vacated.

organizing activity pending or, to the Company’s knowledge, threatened, with respect to the Company or any of its Subsidiaries. 
 (j)

forms of employment offer letters, neither the Company nor its Subsidiaries is a party to or bound by any currently effective employment contract, deferred compensation agreement, bonus plan, incentive plan, profit sharing plan, retirement
agreement, or other employee compensation agreement. 
 3.16 Compliance with Other Instruments. Neither the Company nor any of its
Subsidiaries is in violation or default of any term of its formation documents, Bylaws, or other governing documents, or of any provision of any mortgage, indenture, contract, agreement, instrument or contract to which it is party or by which it is
bound or of any judgment, decree, order or writ other than any such violation that would not have a Material Adverse Effect on the Company and its Subsidiaries, taken as a whole. The execution, delivery, and performance of and compliance with the
Transaction Documents and the issuance and sale of the Shares pursuant hereto, will not, with or without the passage of time or giving of notice, result in any such violation, or be in conflict with or constitute a default under any such term, or
result in the creation of any mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of the Company or any of its Subsidiaries or the suspension, revocation, impairment, forfeiture or
non-renewal of any permit, license, authorization or approval applicable to the Company or any of its Subsidiaries, its business or operations or any of its assets or properties.     

3.17 Tax Returns and Payments. The Company and each of its Subsidiaries have timely filed all tax returns (federal, state and local)
required to be filed by it. All taxes shown to be due and payable on such returns, any assessments imposed, and to the Company’s and each of its Subsidiaries’ knowledge, all other taxes due and payable by the Company and each Subsidiary
have been paid or will be paid prior to the time they become delinquent. Neither the Company nor any Subsidiary has been advised (a) that any of its returns, federal, state or other, have been or are being audited, or (b) of any deficiency
in assessment or proposed judgment to its federal, state or other taxes. The Company, including its Subsidiaries, has no knowledge of any liability of any tax to be imposed upon its properties or assets that is not adequately provided for on its
books. Neither the Company nor any Subsidiary has elected pursuant to the Internal Revenue Code of 1986, as amended (the “Code”), to be treated as a Subchapter S corporation or a collapsible corporation pursuant to Section 1362(a) or
Section 341(f) of the Code, nor has any of them made any other elections pursuant to the Code (other than elections that relate solely to methods of accounting, depreciation or amortization) that would result in a Material Adverse Effect.
Neither the Company nor any Subsidiary has ever had any material tax deficiency proposed or assessed against it and has not executed any waiver of any statute of limitations on the assessment or collection of any tax or governmental charge. None of
the Company’s or any of its Subsidiaries’ federal income tax returns and none of its state income or franchise tax or sales or use tax returns has ever been audited by governmental authorities. Since the Statement Date, neither the Company
nor any Subsidiary has incurred any taxes, assessments or governmental charges other than in the ordinary course of business and the Company and each Subsidiary have made adequate provisions on its books of account for 

 all taxes, assessments and governmental charges with respect to its business, properties and operations for
such period. The Company and each Subsidiary have withheld or collected from each payment made to each of its employees, the amount of all taxes (including, but not limited to, federal income taxes, Federal Insurance Contribution Act taxes and
Federal Unemployment Tax Act taxes) required to be withheld or collected therefrom, and has paid the same to the proper tax receiving officers or authorized depositories. 

3.18 Obligations of Management. Each officer and Key Employee of the Company and its Subsidiaries is currently devoting substantially
all of his or her business time to the conduct of the business of the Company. The Company is not aware that any officer or Key Employee of the Company or any Subsidiary is planning to work less than full time at the Company or any Subsidiary, as
applicable, in the future. No officer or Key Employee is currently working or, to the Company’s knowledge, plans to work for a competitive enterprise, whether or not such officer or Key Employee is or will be compensated by such enterprise.

 3.19 Registration Rights and Voting Rights. Except as provided in this Agreement, the Company is under no contractual obligation to
register under the Securities Act any of its presently outstanding securities or any of its securities that may subsequently be issued. To the Company’s knowledge, other than the Prior Agreements, which have been terminated prior to the date of
this Agreement, no stockholder of the Company has entered into any agreement with respect to the voting of capital shares of the Company. 

3.20 Brokers and Finders. Other than the Placement Agent, the Company has not retained any investment banker, broker or finder in
connection with the sale of the Shares. 
 3.21 Governmental Consents. 

(a) No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any United States
federal, state, local or provincial governmental authority on the part of the Company is required in connection with the consummation of the transactions contemplated by the Transaction Documents, or in order to secure an exemption from registration
under the Securities Act and qualification under the California Corporate Securities Laws and other applicable blue sky laws of the Shares, except such as have been duly and validly obtained or filed, or with respect to any filings that may be made
after the Closing, as will be duly and validly filed in a timely manner.     
 (a) With respect to the Shares to be
offered and sold hereunder in reliance on Rule 506 under the Securities Act, none of the Insiders or the Placement Agent, at the time of sale (each, an “Issuer Covered Person” and, together, “Issuer Covered
Persons”), is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act (a “Disqualification Event”), except for a Disqualification Event covered by
Rule 506(d)(2) or (d)(3) of the Securities Act. The Company has exercised reasonable care to determine whether any Issuer Covered Person is subject to a Disqualification Event. 

(b) Assuming (i) the accuracy of the representations and warranties of the Purchasers set forth in ARTICLE 4 hereof, (ii) none
of the Issuer Covered Persons is subject to any Disqualification Event except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3) of the Securities Act, and (C) the Issuer Covered Persons have complied with the “bad
actor” disclosure requirements set forth in Rule 506(e) of the Securities Act and any disclosure requirements in connection with any waiver of the disqualification provisions of Rule 506(d) of the Securities Act, then the offer, issuance and
sale of the Shares to the Purchasers pursuant to the Agreement, are exempt from the registration requirements of the Securities Act.     

3.22 Corporate Documents. The Company’s Restated Certificate and bylaws, as amended to date and as presently in effect, are in the
form previously provided to the Purchasers. 
 3.23 Minute Books. The minute books of the Company contain a complete summary of all

 3.24 Disclosure. The Company has provided the Purchasers with all the information
that the Purchasers have requested for deciding whether to acquire the Shares and all information that the Company believes is reasonably necessary to enable the Purchasers to make such a decision, including certain of the Company’s projections
describing its proposed business (collectively, the “Information”). To the Company’s knowledge, none of the representations or warranties of the Company contained in this Agreement, as modified by the Disclosure Schedule, or
any certificate furnished or to be furnished to the Purchasers at the Closing (when read together) contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained herein or
therein not misleading in light of the circumstances under which they were made. The Company represents that the assumptions, projections and predictions contained in the Information were made in good faith and that there is a reasonable basis
therefor; however, the Company does not warrant that it will achieve any such projections or that its assumptions or predictions will be accurate. 

3.25 No Conflict of Interest. Neither the Company nor any Subsidiary is indebted, directly or indirectly, to any of its officers or
directors or to their respective spouses or children, in any amount whatsoever other than in connection with expenses or advances of expenses incurred in the ordinary course of business or relocation expenses of employees. To the Company’s
knowledge, none of the Company’s or its Subsidiaries’ officers or directors, or any members of their immediate families, are, directly or indirectly, indebted to the Company or any of its Subsidiaries (other than in connection with
purchases of the Company’s stock) or have any direct or indirect ownership interest in any firm or corporation with which the Company or any of its Subsidiaries is affiliated or with which the Company or any of its Subsidiaries has a business
relationship, or any firm or corporation which competes with the Company, except that officers, directors and/or stockholders of the Company or any of its Subsidiaries may own stock in (but not exceeding two percent of the outstanding capital stock
of) any publicly traded company that may compete with the Company. Neither the Company nor any Subsidiary is a guarantor or indemnitor of any indebtedness of any other person, firm or corporation. 

3.26 Environmental and Safety Laws. To the Company’s knowledge, neither the Company nor any of its Subsidiaries is in violation of
any applicable statute, law or regulation relating to the environment or occupational health and safety, and no material expenditures are or will be required in order to comply with any such existing statute, law or regulation.

(subject to reasonable deductions) to allow the Company to replace any of its material properties that might be damaged or destroyed in a material manner. 

3.28 Permits. The Company has all franchises, permits, licenses and any similar authority necessary for the conduct of its business, the
lack of which could reasonably be expected to have a Material Adverse Effect. The Company is not in default in any material respect under any of such franchises, permits, licenses or other similar authority. 

3.29 83(b) Elections. To the Company’s knowledge, all elections and notices under Section 83(b) of the Code have been or will
be timely filed by all individuals who have acquired unvested shares of the Company’s Common Stock. 
 3.30 Real Property Holding
Corporation. The Company is not now and has never been a “United States real property holding corporation” as defined in the Code and any applicable regulations promulgated thereunder. The Company has filed with the Internal Revenue
Service all statements, if any, with its United States income tax returns which are required under the Code and such regulations. 
 3.31
Data Privacy. In connection with the Company’s collection, storage, transfer (including any transfer across national borders) and/or use of any personally identifiable information from any individuals, including any customers,
prospective customers, employees and/or other third parties (collectively “Personal Information”), to the Company’s knowledge, the Company is and has been in material compliance with all applicable laws in all relevant
jurisdictions, the Company’s privacy policies and the requirements of any contract or codes of conduct to which the Company is a party. The Company has commercially reasonable physical, technical, organizational and administrative security
measures and policies in place to protect all Personal Information collected by it or on its behalf from and against unauthorized access, use and/or disclosure. The Company is and has been in compliance in all material respects with all applicable
laws relating to data loss, theft and breach of security notification obligations. 

 3.32 Scope of Liability for the Company. Liability for the Company for any breach of
the representations and warranties that are qualified by “knowledge” contained in this ARTICLE 3 shall be limited to only those situations in which the Company has knowledge that the representation and warranty in question was false as of
the applicable Closing Date. All references to any “knowledge” of the Company and/or the Subsidiaries in this ARTICLE 3 shall mean to the knowledge of each of Bob Plaschke, Jim Walker, Jeff Pon, Joe Hooks, Peter Liu, Bengt Jonassen and
Chuck Becher and the knowledge that each of the foregoing would reasonably be expected to have obtained in the reasonable and diligent performance of their Company duties. 

3.33 No Directed Selling Efforts or General Solicitation. Neither the Company nor, to the Company’s Knowledge, any Person acting on
its behalf has conducted any general solicitation or general advertising (as those terms are used in Regulation D) in connection with the offer or sale of any of the Shares.

Person will have, as a result of the transactions contemplated by the Transaction Documents, any valid right, interest or claim against the Company or upon any other Purchaser for any commission, fee or other compensation pursuant to any agreement,

The Company shall pay, and hold the Purchasers harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and out-of-pocket expenses) arising in connection with any such claim for fees pursuant to any such agreement, arrangement or understanding entered into by or on behalf of the
Company.     
 ARTICLE 4 

REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS 

Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants, as of the date of each Closing in which such Purchaser
purchases Shares, to the Company and to the Placement Agent as follows (unless as of a specific date therein): 
 4.1 Organization;
Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership,
limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of
the Transaction Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable,
on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding
obligation of such Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution
provisions may be limited by applicable law. 
 4.2 Purchaser Status. At the time such Purchaser was offered the Shares, it was, and
as of the date hereof it is, an “accredited investor” as defined in Rule 501 under the Securities Act. Such Purchaser is not a broker-dealer registered under Section 15 of the Exchange Act. Such Purchaser is acting alone in its
determination as to whether to invest in the Shares. Such Purchaser is not a party to any voting agreements or similar arrangements 

 with respect to the Shares. Except as expressly disclosed in a Schedule 13D or Schedule 13G (or amendments
thereto) filed by such Purchaser with the Commission with respect to the beneficial ownership of the Company’s Common Stock, such Purchaser is not a member of a partnership, limited partnership, syndicate, or other group for the purpose of
acquiring, holding, voting or disposing of the Shares. 
 4.3 Certain Transactions and Confidentiality. Other than consummating the
transactions contemplated hereunder, such Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any purchases or sales, including Short Sales, of the
securities of the Company during the period commencing as of the time that such Purchaser was first contacted by the Company, the Placement Agent or any other Person regarding the transactions contemplated hereby and ending immediately prior to the
date hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct
knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager
that made the investment decision to purchase the Shares covered by this Agreement. Such Purchaser, its Affiliates and authorized representatives and advisors who are aware of the transactions contemplated by the Transaction Documents, maintained
the confidentiality of all disclosures made to it in connection with such transactions (including the existence and terms of such transactions). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a
representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future.    

 4.4 General Solicitation; Pre-Existing Relationship. Such Purchaser is not purchasing the
Shares as a result of any advertisement, article, notice or other communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general
solicitation or general advertisement. Such Purchaser also represents that such Purchaser was contacted regarding the sale of the Shares by the Company or the Placement Agent (or an authorized agent or representative of the Company or the Placement
Agent) with which such Purchaser had a substantial pre-existing relationship. 
 4.5
Purchase Entirely for Own Account. The Shares to be received by such Purchaser hereunder will be acquired for such Purchaser’s own account, not as nominee or agent, and not with a view to the resale or distribution of any
part thereof in violation of the Securities Act, and such Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same in violation of the Securities Act without prejudice, however, to such
Purchaser’s right at all times to sell or otherwise dispose of all or any part of such Shares in compliance with applicable federal and state securities laws. Nothing contained herein shall be deemed a representation or warranty by such
Purchaser to hold the Shares for any period of time. 
 4.6 Experience of Such Purchaser. Such Purchaser, either alone or together
with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Shares, and has so evaluated the merits and
risks of such investment. Such Purchaser is able to bear the economic risk of an investment in the Shares and, at the present time, is able to afford a complete loss of such investment. 

4.7 Disclosure of Information. Such Purchaser has had an opportunity to receive all information related to the Company requested by it
and to ask questions of and receive answers from the Company and the Placement Agent regarding the Company, its business and the terms and conditions of the offering of the Shares. Neither such inquiries nor any other due diligence investigation
conducted by such Purchaser shall modify, limit or otherwise affect such Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement. 

4.8 Placement Agent. Such Purchaser hereby acknowledges and agrees that it has independently evaluated the merits of its decision to
purchase the Shares, and that (i) Placement Agent is acting solely as placement agent in connection with the execution, delivery and performance of the Transaction Documents and is not acting as an underwriter or in any other capacity and is
not and shall not be construed as a fiduciary for such Purchaser, the Company or any other Person in connection with the execution, delivery and performance of the Transaction Documents, and (ii) such Purchaser has not relied on the Placement
Agent or its officers, directors, employees, attorneys or Affiliates with respect to the negotiation, execution or performance of the Transaction Documents or any representation or warranty made in, in connection with, or as an inducement to the
Transaction Documents.     

 4.9 Interested Stockholders. Each Purchaser that is an “Interested
Stockholder” (as such term is defined in Section 203 of the General Corporation Law of the State of Delaware) represents and warrants that either (a) it has been an Interested Stockholder for at least three years prior to the date
hereof or (b) the transaction that resulted in such Purchaser becoming an Interested Stockholder was approved by the Board of Directors or a duly authorized committee thereof. 

4.10 Restricted Securities. Such Purchaser understands that the Shares are “restricted securities” and have not been
registered under the Securities Act and may not be offered, resold, pledged or otherwise transferred except (i) pursuant to an exemption from registration under the Securities Act or pursuant to an effective registration statement in compliance
with Section 5 under the Securities Act and (ii) in accordance with all applicable securities laws of the states of the United States and other jurisdictions. 

4.11 No Rule 506 Disqualifying Activities. Such Purchaser has not taken any of the actions set forth in, and is not subject to, the
disqualification provisions of Rule 506(d)(1) of the Securities Act. 
 4.12 Compliance. No part of the funds being used by such
Purchaser to acquire the Shares has been, or shall be, directly or indirectly derived from, or related to, any activity that may contravene United States federal or state or non-United States laws or
regulations. 
 4.13 Residency. Such Purchaser is a resident of or an entity organized under the jurisdiction specified below its
address on Exhibit A hereto. 
 4.14 ERISA. If such Purchaser is (1) an employee benefit plan subject to Title I of ERISA,
(2) a plan or account subject to Section 4975 of the Code or (3) an entity deemed to hold “plan assets” of any such plan or account, such Purchaser hereby represents and warrants, solely for purposes of assisting the
Placement Agent in relying on the exception from fiduciary status under U.S. Department of Labor Regulations set forth in Section 29 CFR 2510.3-21(c)(1), that a fiduciary acting on its behalf is causing
such Purchaser to enter into the Transaction Documents and the transactions contemplated hereby and thereby and that such fiduciary: 
 (a)
is an entity specified in Section 29 CFR 2510.3-21(c)(1)(i)(A)-(E); 
 (b) is independent (for
purposes of Section 29 CFR 2510.3-21(c)(1)) of each Placement Agent; 
 (c) is capable of
evaluating investment risks independently, both in general and with regard to particular transactions and investment strategies, including such Purchaser’s transactions under the Transaction Documents; 

(d) has been advised that, with respect to each Placement Agent, neither such Placement Agent nor any of its respective affiliates has
undertaken or will undertake to provide impartial investment advice, or has given or will give advice in a fiduciary capacity, in connection with such Purchaser’s transactions contemplated by the Transaction Documents; 

(e) is a “fiduciary” under Section 3(21)(a) of ERISA or Section 4975(e)(3) of the Code, or both, as applicable, with
respect to, and is responsible for exercising independent judgment in evaluating, such Purchaser’s transactions contemplated hereby; and 

(f) understands and acknowledges that no fees, compensation arrangements or financial interests provided for in connection with the
transactions contemplated hereby is a fee or other compensation for the provision of investment advice, and that neither the Placement Agent nor any of its affiliates, nor any of their respective directors, officers, members, partners, employees,
principals or agents, has received or will receive a fee or other compensation from such Purchaser or such fiduciary for the provision of investment advice in connection with such Purchaser’s transactions contemplated by the Transaction
Documents. 

 4.15 Securities Laws Representations and Covenants of the Foreign Purchasers. 

(a) If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended, or
if the Purchaser is a US subsidiary or affiliate of a foreign parent company, the “Foreign Purchaser”), the Foreign Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction
in connection with any invitation to subscribe for the Shares or any use of this Agreement or the other Transaction Documents, including (i) the legal requirements within its jurisdiction for the purchase of the Shares, (ii) any foreign
exchange restrictions applicable to such purchase, (iii) any government or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption,
sale or transfer of the Shares. The Foreign Investor further represents that either (x) it does not now, nor will it after the Closing, hold ten percent (10%) or greater, directly or indirectly, of the voting interest in the Company or
(y) if it does or will, the Foreign Purchaser shall provide such information as the Company may request to comply with state, federal, or local regulations. The Company’s offer and sale and the Foreign Purchaser’s subscription and
payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of the Foreign Purchaser’s jurisdiction. 

(b) Each Foreign Purchaser represents and warrants to the Company as follows: 

(i) The Foreign Purchaser is not a “U.S. Person” (as defined under Regulation S of the Securities Act) and that the Shares to be
purchased by the Foreign Purchaser will be acquired for investment for the Investor’s own account, not as a nominee or agent, and not for the account or benefit of, a U.S. Person, and not with a view to the resale or distribution of any part
thereof in the United States and that the Foreign Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same. 

(ii) The Foreign Purchaser represents that it does not have any contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person in the United States or to a U.S. Person, or any hedging transaction with any third person in the United States or to a United States resident, with respect to any of the Shares.

 (iii) The Foreign Purchaser understands that the Shares are not registered under the Securities Act on the ground that the sale to the
Foreign Purchaser as provided for in this Agreement and the issuance of Shares to such Foreign Purchaser hereunder is exempt from registration under the Securities Act pursuant to Regulation S thereof, and that the Company’s reliance on such
exemption is predicated on the Foreign Purchaser’s representations set forth herein. The Foreign Purchaser hereby agrees to resell the Shares only in accordance with the provisions of Regulation S, pursuant to registration under the Securities
Act, or pursuant to an exemption from registration. The Foreign Purchaser further agrees not to engage in hedging transactions with regard to such Shares unless in compliance with the Securities Act. 

(c) The Foreign Purchaser has been informed, and it understands and agrees that a legend substantially similar to the one set forth below will
be placed on the certificates for the Shares and stop transfer instructions will be placed with the transfer agent of the Shares: 

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”),
OR UNDER THE SECURITIES LAWS OF ANY STATES IN THE UNITED STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES
LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT
AND ANY APPLICABLE STATE SECURITIES LAWS. FURTHER, THESE SECURITIES MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO 

 OR FOR THE ACCOUNT OR BENEFIT OF U.S. PERSONS (AS DEFINED IN REGULATION S UNDER THE
ACT) (I) AS PART OF THEIR DISTRIBUTION AT ANYTIME OR (II) OTHERWISE UNTIL THE EXPIRATION OF THE APPLICABLE RESTRICTED PERIOD AS DETERMINED IN ACCORDANCE WITH REGULATION S, EXCEPT IN EITHER CASE IN ACCORDANCE WITH REGULATIONS UNDER THE ACT.
IN ADDITION, NO HEDGING TRANSACTION MAY BE CONDUCTED WITH RESPECT TO THESE SHARES UNLESS SUCH TRANSACTIONS ARE IN COMPLIANCE WITH THE ACT.” 

4.16 Commissions. No Person will have, as a result of the transactions contemplated by the Transaction Documents, any valid right,
interest or claim against such Purchaser or upon the Company or any other Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of such Purchaser. Such Purchaser
shall pay, and hold the Company and other Purchasers harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and
out-of-pocket expenses) arising in connection with any such claim for fees pursuant to any such agreement, arrangement or understanding entered into by or on behalf of
such Purchaser.     
 The Company acknowledges and agrees that the representations contained in ARTICLE 4 shall
not modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction Document or any other document
or instrument executed and/or delivered in connection with this Agreement or the consummation of the transaction contemplated hereby.

 5.1 Registration Statement.     

(a) On or prior to the Initial Filing Deadline, the Company shall prepare and file with the Commission a Registration Statement covering the
resale of all Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be on Form S-1 (or, if applicable, on another appropriate form in
accordance with the Securities Act) and shall contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement) the “Plan of Distribution” in substantially the
form attached hereto as Exhibit F. Notwithstanding any other provision of this ARTICLE 5, if the staff of the Commission does not permit all of the Registrable Securities to be registered on the initial Registration Statement filed
pursuant to this Section 5.1(a) (the “Initial Registration Statement”) or requires any Purchaser to be named as an “underwriter”, then the Company shall use commercially reasonable efforts to persuade the staff of the
Commission that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that none of the Purchasers is an
“underwriter”; provided, however, that in no event shall the Company be required to continue discussions with the staff of the Commission if the Company reasonably determines that doing so is reasonably likely to cause
the Company to incur liquidated damages pursuant to Section 5.1(d) because of a failure to have the Initial Registration Statement declared effective prior to the Initial Effectiveness Deadline. In the event that, despite the
Company’s commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, Securities Act Rules Compliance and
Disclosure Interpretation 612.09 and compliance with the terms of this Section 5.1(a), the staff of the Commission refuses to alter its position, the Company shall (i) remove from the Registration Statement such portion of the
Registrable Securities (the “Cut Back Shares”) as determined below and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the staff of the Commission may require
to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name any Purchaser as an
“underwriter” in such Registration Statement without the prior written consent of such Purchaser; provided, further, that if any such Purchaser refuses to be named as an underwriter as required by the SEC Restrictions,
such Purchaser’s Registrable Securities shall be removed from the Initial Registration Statement and such Registrable Securities shall be deemed to constitute Cut Back Shares and the provisions of this Section 5.1(a) shall apply to
such Cut Back Shares. Except as provided in the immediately preceding sentence, any cut-back imposed pursuant to this Section 5.1(a) shall be allocated among the Purchasers on a pro rata basis by
removing Registrable Securities on a pro rata basis based on 

 the total number of unregistered Registrable Securities held by such Purchasers, in each case unless the SEC
Restrictions otherwise require or provide or the Purchasers otherwise agree. In the event of a cutback hereunder, the Company shall give each Purchaser at least three (3) Trading Days’ prior written notice along with the calculations as to
such Purchaser’s allotment. In furtherance of the foregoing, each Purchaser shall promptly notify the Company when it has sold substantially all of its Registrable Securities covered by the Initial Registration Statement (or any
Additional Registration Statement (as defined below)) so as to enable the Company to determine whether it can file one or more additional registration statements covering the Cut Back Shares and the Company agrees that it shall file one or more
additional Registration Statements (each, an “Additional Registration Statement”) as promptly as possible, and in any event on or prior to the applicable Additional Filing Deadline, successively using its commercially reasonable
efforts to register on each such Additional Registration Statement the maximum number of remaining Cut Back Shares that continue to constitute Registrable Securities until all of the Cut Back Shares that continue to constitute Registrable Securities
have been registered with the Commission. 
 (b) The Company shall use its commercially reasonable efforts to cause each Registration
Statement to be declared effective by the Commission as promptly as possible after the filing thereof, but in any event prior to the applicable Effectiveness Deadline, and shall use commercially reasonable efforts to keep the Registration Statement
continuously effective under the Securities Act until the earlier of (i) the date that all Registrable Securities covered by such Registration Statement have been sold or can be sold publicly without restriction or limitation under Rule 144
(including, without limitation, the requirement to be in compliance with Rule 144(c)(1)) or (ii) the date that is two (2) years following the Closing Date (the “Effectiveness Period”). Not later than two Trading Days after
a Registration Statement is declared effective, the Company shall file a prospectus supplement for any Registration Statement to the extent required pursuant to Rule 424. 

(c) The Company shall notify the Purchasers in writing promptly (and in any event within two Trading Days) after receiving notification from
the Commission that a Registration Statement has been declared effective. 
 (d) Should an Event (as defined below) occur, then upon the
occurrence of such Event and on every monthly anniversary thereof until the applicable Event is cured, the Company shall pay to each Purchaser an amount in cash, as liquidated damages and not as a penalty, equal to one percent (1.0%) of the
aggregate Share Purchase Price of the Registrable Securities then held by the Purchaser, subject to adjustment as provided below (which remedy shall be exclusive of any other remedies available under this Agreement or under applicable law);
provided, however, that the total amount of payments pursuant to this Section 5.1(d) shall not exceed, when aggregated with all such payments paid to the applicable Purchaser, five percent (5%) of the aggregate Share
Purchase Price hereunder. The payments to which a Purchaser shall be entitled pursuant to this Section 5.1(d) are referred to herein as “Event Payments.” Any Event Payments payable pursuant to the terms hereof shall
apply on a pro rated basis for any portion of a month prior to the cure of an Event. In the event the Company fails to make Event Payments in a timely manner, such Event Payments shall bear interest at the rate of one percent (1.0%) per month
(prorated for partial months) until paid in full. All pro rated calculations made pursuant to this paragraph shall be based upon the actual number of days in such pro rated month. The parties agree that the Company will not be liable for any Event
Payments under this Section 5.1(d) arising with respect to any period after the expiration of the Effectiveness Period. The parties further agree that Company will not be liable for any Event Payments under this Section 5.1(d) with
respect to any Cut Back Shares that are removed from a Registration Statement pursuant to Section 5.1(a); accordingly, any Event Payments shall be calculated, as to each Purchaser, to apply only to the percentage of such Purchaser’s
Registrable Securities that are both (x) then issued and outstanding and (y) permitted in accordance with SEC Guidance to be included in such Registration Statement. Notwithstanding the foregoing, the applicable Filing Deadline or
Effectiveness Deadline for a Registration Statement shall be extended without Event Payments hereunder in the event that the Company’s failure to file or obtain the effectiveness of such Registration Statement on a timely basis results from
(i) the failure of any Purchaser, other than a Purchaser that is also a director or officer of the Company, to timely provide the Company with information reasonably requested by the Company and necessary to complete the Registration Statement
in accordance with the requirements of the Securities Act or (ii) events or circumstances that are not in any way attributable to the Company’s actions or inactions, including, but not limited to, the failure of any Purchaser, other than a
Purchaser that is also a director or officer of the Company, to promptly notify the Company when it has sold substantially all of its Registrable Securities covered by the Initial Registration Statement or any Additional Registration Statement or to
otherwise comply with the terms of this Agreement, and in any event, no Purchaser causing the failure described in (i) or (ii), above shall be entitled to Event Payments relating to the failure caused by such Purchaser. 

 For such purposes, each of the following shall constitute an “Event”: 

(x) a Registration Statement is not filed on or prior to its Filing Deadline or is not declared effective on or prior to its Effectiveness
Deadline; and 
 (y) except as provided for in Section 5.1(e) (the “Excluded Events”), after the Effective Date of a
Registration Statement and through the end of the Effectiveness Period, a Purchaser is not permitted to sell the applicable Registrable Securities subject to such Registration Statement. 

(e) Notwithstanding anything in this Agreement to the contrary, the Company may, by written notice to the Purchasers, suspend sales under a
Registration Statement after the Effective Date thereof and/or require that the Purchasers immediately cease the sale of shares of Common Stock pursuant thereto and/or defer the filing of any Additional Registration Statement if the Company is
engaged in a material merger, acquisition or sale or any other pending development that the Company believes may be material, and the Board of Directors determines in good faith, by appropriate resolutions, that, as a result of such activity,
(A) it would be materially detrimental to the Company (other than as relating solely to the price of the Common Stock) to maintain a Registration Statement at such time or (B) it is in the best interests of the Company to suspend sales
under such registration at such time. Upon receipt of such notice, each Purchaser agrees to immediately discontinue any sales of Registrable Securities pursuant to such Registration Statement until such Purchaser is advised in writing by the Company
that the current Prospectus or amended Prospectus, as applicable, may be used. In no event, however, shall this right be exercised to suspend sales beyond the period during which (in the good faith determination of the Board of Directors) the
failure to require such suspension would be materially detrimental to the Company. The Company’s rights under this Section 5.1(e) may be exercised for a period of no more than 20 Trading Days at a time with a subsequent permitted
trading window of at least 90 Trading Days, and not more than two times in any twelve-month period. Immediately after the end of any suspension period under this Section 5.1(e), the Company shall take all necessary actions (including
filing any required supplemental prospectus) to restore the effectiveness of the applicable Registration Statement and the ability of the Purchasers to publicly resell their Registrable Securities pursuant to such effective Registration Statement.

 5.2 Registration Procedures. In connection with the Company’s registration obligations hereunder, the Company shall: 

(a) Not less than five Trading Days prior to the filing of a Registration Statement or any related Prospectus or any amendment or supplement
thereto, furnish via email to those Purchasers or their counsels who have supplied the Company with email addresses copies of all such documents proposed to be filed, which documents (other than any document that is incorporated or deemed to be
incorporated by reference therein) will be subject to the review of such Purchasers. The Company shall reflect in each such document when so filed with the Commission such comments regarding the Purchasers and the plan of distribution as the
Purchasers may reasonably and promptly propose no later than two Trading Days after the Purchasers have been so furnished with copies of such documents as aforesaid. 

(b) (i) Subject to Section 5.1(e), prepare and file with the Commission such amendments, including post-effective amendments,
to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep the Registration Statement continuously effective, as to the applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; and (iii) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the applicable period in accordance with the intended methods of disposition by the Purchasers thereof set forth in the Registration Statement as so amended or in such Prospectus as
so supplemented. 

 (c) Notify the Purchasers as promptly as reasonably possible, and if requested by the
Purchasers, confirm such notice in writing no later than two Trading Days thereafter, of any of the following events: (i) the Commission notifies the Company whether there will be a “review” of any Registration Statement or the
receipt of any comments or correspondence from the Commission; (ii) any Registration Statement or any post-effective amendment is declared effective; (iii) the Commission issues any stop order suspending the effectiveness of any
Registration Statement or initiates any Proceedings for that purpose; (iv) the Company receives notice of any suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction, or the
initiation or threat of any Proceeding for such purpose; (v) the financial statements included in any Registration Statement become ineligible for inclusion therein; or (vi) the Company becomes aware that any Registration Statement or
Prospectus or other document contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made,
not misleading. 
 (d) Use reasonable best efforts to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order
suspending the effectiveness of any Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as possible. 

(e) If requested by a Purchaser, provide such Purchaser, without charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the
Commission; provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system. 

(f) Promptly deliver to each Purchaser, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus)
and each amendment or supplement thereto as such Persons may reasonably request. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Purchasers in connection with the offering and
sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto to the extent permitted by federal and state securities laws and regulations. 

(g) Prior to any resale of Registrable Securities by a Purchaser, use commercially reasonable best efforts to register or qualify or cooperate
with the selling Purchasers in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions
within the United States as any Purchaser requests in writing, to keep each such registration or qualification (or exemption therefrom) effective for so long as required, but not to exceed the duration of the Effectiveness Period, and to do any and
all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by a Registration Statement; provided, however, that the Company shall not be obligated to
file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction
in which it is not otherwise so subject. 
 (h) Use reasonable best efforts to cause all Registrable Securities covered by a Registration
Statement to be listed or quoted on the Trading Market; 
 (i) If requested by the Purchasers, cooperate with the Purchasers to facilitate
the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by this Agreement and under law,
of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Purchasers may reasonably request. 

(j) Upon the occurrence of any event described in Section 5.2(c)(iii)-(vi), as promptly as reasonably practicable, prepare a
supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be 

 incorporated therein by reference, and file any other required document so that, as thereafter delivered,
neither the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. 
 (k) It shall be a condition precedent to the obligations of the Company to complete the
registration pursuant to this Agreement with respect to the Registrable Securities of any particular Purchaser that such Purchaser furnish to the Company a completed Selling Stockholder Questionnaire in the form proffered by the Company (the
“Selling Stockholder Questionnaire”) and such other information regarding itself, the Registrable Securities and other shares of Common Stock held by it and the intended method of disposition of the Registrable Securities held by it
(if different from the Plan of Distribution set forth on Exhibit F hereto) as shall be reasonably required to effect the registration of such Registrable Securities and shall complete and execute such documents in connection with such registration
as the Company may reasonably request.     
 (l) The Company shall comply with all applicable rules and regulations of
the Commission under the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus, including any supplement or amendment thereof, with the Commission pursuant to Rule 424 under
the Securities Act, promptly inform the Purchasers in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Purchasers are required to make available
a Prospectus in connection with any disposition of Registrable Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder. 

(m) Not identify any Purchaser as an underwriter without its prior written consent in any public disclosure or filing with the Commission or
any Trading Market and any Purchaser being deemed an underwriter by the Commission shall not relieve the Company of any obligations it has under this Agreement; provided, however, that the foregoing shall not prohibit the Company from
including the disclosure found in the “Plan of Distribution” section attached hereto as Exhibit F in the Registration Statement. In addition, and notwithstanding anything to the contrary contained herein, if the Company has received
a comment by the Commission requiring a Purchaser to be named as an underwriter in the Registration Statement (which notwithstanding the reasonable best efforts of the Company is not withdrawn by the Commission) and such Purchaser refuses to be
named as an underwriter in the Registration Statement, such Purchaser’s Registrable Securities shall be removed from the Registration Statement, such Registrable Securities shall be deemed to constitute Cut Back Shares and the Purchaser shall
not be entitled to any Event Payments with respect to such Registration Statement. 
 5.3 Registration Expenses. The Company shall pay
all fees and expenses incident to the performance of or compliance with ARTICLE 5 of this Agreement by the Company, including without limitation (a) all registration and filing fees and expenses, including without limitation those
related to filings with the Commission, any Trading Market, and in connection with applicable state securities or Blue Sky laws, (b) printing expenses (including without limitation expenses of printing certificates for Registrable Securities),
(c) messenger, telephone and delivery expenses, (d) fees and disbursements of counsel for the Company, (e) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated
by this Agreement, (f) all listing fees to be paid by the Company to the Trading Market and (g) reasonable and reasonably-documented fees and disbursements, not to exceed $10,000 in the aggregate, of one counsel for the Purchasers. In no
event shall the Company be responsible for any underwriting, broker or similar fees or commissions of any Purchaser or, except to the extent provided for above or in the Transaction Documents, any legal fees or other costs of the Purchasers. 

5.4 Indemnification. 
 (a)
Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Purchaser, the officers, directors, partners, members, agents and employees of each of them, each Person
who controls any such Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, agents and employees of each such controlling Person, to the fullest
extent permitted by applicable law, from and against any and all Losses, as incurred, arising out of or relating to any violation or alleged violation by the Company of the 

 Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or
any rule or regulation thereunder relating to the offer or sale of the Registrable Securities, any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus or in any amendment or supplement
thereto, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in
the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon
information regarding such Purchaser furnished in writing to the Company by such Purchaser expressly for use therein, or to the extent that such information relates to such Purchaser or such Purchaser’s proposed method of distribution of
Registrable Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use in the Registration Statement, or (B) with respect to any Prospectus, if the untrue statement or omission of material fact contained
in such Prospectus was corrected on a timely basis in the Prospectus, as then amended or supplemented, if such corrected prospectus was timely made available by the Company to the Purchaser, and the Purchaser seeking indemnity hereunder was advised
in writing not to use the incorrect prospectus prior to the use giving rise to Losses. 
 (b) Indemnification by Purchasers. Each
Purchaser shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20
of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final
judgment not subject to appeal or review) arising solely out of any untrue statement of a material fact contained in the Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising out of
or relating to any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they
were made) not misleading, but only to the extent that such untrue statement or omission is contained in any information so furnished by such Purchaser in writing to the Company specifically for inclusion in such Registration Statement or such
Prospectus or to the extent that such untrue statements or omissions are based solely upon information regarding such Purchaser furnished to the Company by such Purchaser in writing expressly for use in the Registration Statement or Prospectus, or
to the extent that such information relates to such Purchaser or such Purchaser’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Purchaser expressly for use in the
Registration Statement (it being understood that the information provided by the Purchaser to the Company in the Questionnaire and the Plan of Distribution set forth on Exhibit F, as the same may be modified by such Purchaser constitutes information
reviewed and expressly approved by such Purchaser in writing expressly for use in the Registration Statement), such Prospectus or such form of Prospectus or in any amendment or supplement thereto. In no event shall the liability of any selling
Purchaser hereunder be greater in amount than the dollar amount of the net proceeds received by such Purchaser upon the sale of the Registrable Securities giving rise to such indemnification obligation. 

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity
hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense
thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such
notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party. 

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed within
15 days of receiving notification of a Proceeding from an Indemnified Party to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; (iii) any counsel engaged by
the applicable Indemnifying Party shall fail to timely commence or diligently conduct the defense of any such claim and such failure has materially prejudiced 

 (or, in the reasonable judgment of the Indemnified Party, is in danger of materially prejudicing) the
outcome of the applicable claim; or (iv) such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to or may exist between the applicable Indemnifying Party and Indemnified Party or that there may be one or
more different or additional defenses, claims, counterclaims or causes of action available to such Indemnified Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of separate counsel shall be at the expense of the Indemnifying Party). It being understood,
however, that the Indemnifying Party shall not, in connection with any one such Proceeding (including separate Proceedings that have been or will be consolidated before a single judge) be liable for the fees and expenses of more than one separate
firm of attorneys at any time for all Indemnified Parties, which firm shall be appointed by a majority of the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written
consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party,
unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. 

All reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within 20 Trading Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent
it is finally judicially determined (not subject to appeal) that such Indemnified Party is not entitled to indemnification hereunder). 
 (d)
Contribution. If a claim for indemnification under Section 5.4(a) or (b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying
such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in
connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among
other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying
Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be
deemed to include, subject to the limitations set forth in Section 5.4(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have
been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. 

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5.4(d) were determined
by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5.4(d), no
Purchaser shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Purchaser from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any
damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 
 The indemnity
and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties, including pursuant to Section 6.6 hereof. 

5.5 Dispositions. Each Purchaser agrees that it will comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement and shall sell its Registrable Securities that it sells pursuant to the Registration Statement in accordance 

 with the Plan of Distribution set forth in the Prospectus. Each Purchaser further agrees that, upon receipt
of a notice from the Company of the occurrence of any event of the kind described in Section 5.2(c)(iii)-(vi), such Purchaser will discontinue disposition of such Registrable Securities under the Registration Statement until such
Purchaser is advised in writing by the Company that the use of the Prospectus, or amended Prospectus, as applicable, may be used. The Company may provide appropriate stop orders to enforce the provisions of this paragraph. Each Purchaser, severally
and not jointly with the other Purchasers, agrees that the removal of the restrictive legend from certificated or uncertificated Shares as set forth in Section 6.1 is predicated upon the Company’s reliance that the Purchaser will
comply with the provisions of this subsection. 
 5.6 No Piggyback on Registrations. Neither the Company nor any of its security
holders (other than the Purchasers in such capacity pursuant hereto) may include securities of the Company in the Registration Statement other than the Registrable Securities.    The Company shall not file any other registration
statements, other than any registration statements on Form S-4 or Form S-8 (each as promulgated under the Securities Act), prior to the Effective Date of the Initial
Registration Statement, provided that this Section 5.6 shall not prohibit the Company from filing amendments to registration statements filed prior to the date of this Agreement. 

5.7 Amendments; Waivers. Notwithstanding anything in this Agreement to the contrary, the provisions of this ARTICLE 5 may be
amended or waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely), with the written consent of (i) the Company and (ii) the Purchaser or
Purchasers holding at least a majority of the then outstanding Registrable Securities. Notwithstanding the foregoing, a waiver or consent to depart from the provisions of this ARTICLE 5 with respect to a matter that relates exclusively to the
rights of Purchasers and that does not directly or indirectly affect the rights of other Purchasers may be given by Purchasers of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the
provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of the immediately preceding sentence. 

ARTICLE 6 
 OTHER
AGREEMENTS OF THE PARTIES 
 6.1 Transfer Restrictions. 

(a) The Shares may only be disposed of in compliance with state and federal securities laws, and each Purchaser agrees that it will sell,
transfer or otherwise dispose of the Shares only in compliance with all applicable state and federal securities laws, and, as applicable, in accordance with the requirements of Section 5.5 hereof. In connection with any transfer of
Shares other than pursuant to an effective registration statement under the Securities Act or Rule 144, to the Company or to an Affiliate of a Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel
selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Shares
under the Securities Act. 
 (b) The Purchasers agree to the imprinting, so long as is required by this Section 6.1, of a legend
on any of the Shares, whether in certificated or uncertificated form, in substantially the following forms, as applicable: 

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT EXCEPT PURSUANT TO A TRANSACTION EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE ACT 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER IN FAVOR OF THE CORPORATION AND/OR ITS
ASSIGNEE(S), AS PROVIDED IN THE BYLAWS OF THE CORPORATION. 

 In addition, if any Purchaser is an Affiliate of the Company, the Shares issued to such
Purchaser shall bear a customary “affiliates” legend. 
 (c) Instruments, whether certificated or uncertificated, evidencing the
Shares shall not contain any legend (including the legends set forth in Section 6.1(b) hereof), (i) while a registration statement (including the Registration Statement) covering the resale of such Shares is effective under the
Securities Act, (ii) if such Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Shares and without volume or manner-of-sale restrictions, (iii) following any sale of such Shares pursuant to Rule 144 or (iv) if such legend is not required under applicable requirements of the
Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) or otherwise. Upon request by any Purchaser, following such time as a legend is no longer required under this Section 6.1(c),
the Company shall cause its counsel to issue a legal opinion to the Transfer Agent (if required by the Transfer Agent) to effect the removal of the legend hereunder from any Shares. The Company agrees that following such time as a legend is no
longer required under this Section 6.1(c), no later than three Trading Days following the delivery by a Purchaser to the Company of all of (i) an instrument, whether certificated or uncertificated, representing the Shares issued
with a restrictive legend, (ii) a written request addressed to the Company that such restrictive legend be removed, and (iii) customary broker and representation letters in form and substance reasonably satisfactory to the Company (the
date that all of such foregoing information and documentation is delivered to the Company by a Purchaser, the “Removal Request Date” and such third Trading Day thereafter, the “Legend Removal Date”), the Company
will deliver or cause to be delivered to such Purchaser an instrument, certificated or uncertificated as directed by such Purchaser, representing such Shares that is free from all restrictive and other legends. The Company may not make any notation
on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 6.1(c). Shares subject to legend removal hereunder shall, unless otherwise directed by a Purchaser, be
transmitted by the Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser. 

(d) In addition to a Purchaser’s other available remedies, if the Company shall fail for any reason (other than failure of such Purchaser
to comply with the provisions set forth in Section 6.1) to deliver any Shares without a restrictive legend by the Legend Removal Date, and if on or after the Legend Removal Date such Purchaser purchases (in an open market transaction or
otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Purchaser of any portion of such Shares that such Purchaser anticipated receiving without legend by the Legend Removal Date (a
“Buy-In”), then the Company shall, within two (2) Trading Days after such Purchaser’s request and in such Purchaser’s discretion, either: (i) pay cash to such Purchaser in
an amount equal to such Purchaser’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased by such Purchaser (the “Buy-In Price”), at
which point the Company’s obligation to deliver such unlegended Shares shall terminate, or (ii) promptly honor its obligation to deliver to such Purchaser such unlegended Shares as provided above and pay cash to such Purchaser in an amount
equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Shares, times (B) the Fair Market Value of one share of Common Stock as of the Removal Request Date. 

6.2 Furnishing of Information; Public Information. In order to enable the Purchasers to sell Shares under Rule 144, for a period of one
year from the effective date of the Company’s Initial Registration Statement, the Company covenants to use commercially reasonable efforts to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all
reports that would be required to be filed by the Company after the effective date of the Company’s Initial Registration Statement pursuant to Section 13(a) or 15(d) of the Exchange Act. During such one year period, if the Company is not
required to file reports pursuant to Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the Holders and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act annual and quarterly
financial statements, together with a discussion and analysis of such financial statements in form and substance substantially similar to those that would otherwise be required to be included in reports required by Section 13(a) or 15(d) of the
Exchange Act, as well as any other information required thereby, in the time period that such filings would have been required to have been made under the Exchange Act. 

6.3 Use of Proceeds. The Company shall use the net proceeds from the sale of the Shares hereunder for funding research and development
and its other operations, or for working capital and other general corporate purposes, and shall not use any such proceeds in violation of FCPA or OFAC regulations. For clarity, the net proceeds will not be used to repurchase existing stockholder
shares or to pay down non-revolving debt. 
  

 6.4 Indemnification of Purchasers. Subject to the provisions of this
Section 6.4, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling Persons (each, a “Purchaser
Party”) harmless from any and all Losses that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this
Agreement or in the other Transaction Documents or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such
Purchaser Parties, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is found by a court of competent jurisdiction in a final, non-appealable decision to be
based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Parties may have with any such stockholder or any violations by such
Purchaser Parties of state or federal securities laws or any conduct by such Purchaser Parties which constitutes fraud, gross negligence, willful misconduct or malfeasance of such Purchaser Party). If any action shall be brought against any
Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own
choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense
of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ
counsel reasonably acceptable to such Purchaser Party or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser
Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a
Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is found by a court of
competent jurisdiction in a final, non-appealable decision to be attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser
Party in this Agreement or in the other Transaction Documents. No Purchaser shall be liable for the indemnification obligations of any other Purchaser and no Purchaser’s liability shall exceed the purchase price paid for the Shares pursuant to
this Agreement. The indemnification required by this Section 6.4 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity
agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law. 

6.5 Reservation of Common Stock. The Company has reserved and the Company shall continue to reserve and keep available at all times,
free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Shares pursuant to this Agreement (the “Required Minimum”). If, on any date, the number of authorized but
unissued (and otherwise unreserved) shares of Common Stock is less than the Required Minimum on such date, then, not later than the Company’s next annual meeting of stockholders occurring on or after the 60th day following such date, the Board
of Directors shall use commercially reasonable efforts to amend the Company’s certificate of incorporation to increase the number of authorized but unissued shares of Common Stock to at least the Required Minimum at such time. 

6.6 Listing of Common Stock; Uplisting to The NASDAQ Capital Market. The Company will use its commercially reasonable efforts to effect
the quotation of its Common Stock on the OTC and will comply in all material respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the applicable OTC trading market, and will use its commercially
reasonable efforts to effect an uplisting to NASDAQ as soon as reasonably practicable. In addition, the Purchasers and the Company agree to cooperate in good faith, if 

 necessary, to restructure the transactions contemplated by the Transaction Documents such that they do not
contravene the rules and regulations of the Principal Trading Market; provided, however, that such restructuring does not impact the economic interests of the Purchasers contemplated by the Transaction Documents. Each Purchaser agrees
to provide information reasonably requested by the Company to comply with this Section 6.6. The provisions of this Section 6.6 shall terminate and be of no further force and effect upon the expiration of the Effectiveness
Period. 
 6.7 Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be
offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration is also offered to all of the parties to this Agreement. For clarification purposes, this provision
constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in
concert or as a group with respect to the purchase, disposition or voting of Shares or otherwise. 
 6.8 Form D; Blue Sky Filings. The
Company agrees to timely file a Form D with respect to the Shares as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably determine is
necessary in order to obtain an exemption for, or to qualify the Shares for, sale to the Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such
actions promptly upon request of any Purchaser. Each Purchaser shall provide any information reasonably requested by the Company to comply with this Section 6.18. 

6.9 Acknowledgment Regarding Purchaser’s Trading Activity. Anything in this Agreement or elsewhere herein to the contrary
notwithstanding (except for Section 4.3), it is understood and acknowledged by the Company that: (i) none of the Purchasers has been asked by the Company to agree, nor has any Purchaser agreed, to desist from purchasing or selling, long
and/or short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Shares for any specified term, (ii) past or future open market or other transactions by any Purchaser,
specifically including, without limitation, Short Sales or “derivative” transactions, before or after the closing of this or future private placement transactions, may negatively impact the market price of the Company’s
publicly-traded securities, (iii) any Purchaser, and counter-parties in “derivative” transactions to which any such Purchaser is a party, directly or indirectly, may presently have a “short” position in the Common Stock and
(iv) each Purchaser shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. The Company further understands and acknowledges that (y) one or more
Purchasers may engage in hedging activities at various times during the period that the Shares are outstanding, and (z) such hedging activities (if any) could reduce the value of the existing stockholders’ equity interests in the Company
at and after the time that the hedging activities are being conducted. Except as contemplated by Section 4.3 hereof, Company acknowledges that such aforementioned hedging activities do not constitute a breach of any of the Transaction
Documents. 
 6.10 Other Actions. Except as otherwise set forth in this Agreement, from the date of this Agreement until the earlier
to occur of the Closing or the termination of this Agreement in accordance with the terms hereof, the Company and the Purchasers shall not, and shall not permit any of their respective Affiliates to, take, or agree or commit to take, any action that
would reasonably be expected to, individually or in the aggregate, prevent, materially delay or materially impede the consummation of the transactions contemplated by this Agreement. 

ARTICLE 7 
 MISCELLANEOUS

 7.1 Fees and Expenses. Except as set forth in Section 5.3, the parties hereto shall pay their own costs and expenses in
connection herewith, including all attorneys’ fees.     
 7.2 Entire Agreement. The Transaction Documents,
together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such
matters, which the parties acknowledge have been merged into such documents, exhibits and schedules; provided, however, that any nondisclosure or 

 confidentiality agreement previously entered into between the Company and any Purchaser(s) shall remain in
full force and effect. At or after the Closing, and without further consideration, the Company will execute and deliver to the Purchasers, and the Purchasers will execute and deliver to the Company, such further documents as may be reasonably
requested in order to give practical effect to the intention of the parties under the Transaction Documents.     
 7.3
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of: (a) the date of transmission, if such

 7.4 Amendments; Waivers. Subject to the
provisions of Section 5.7, no provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Principal Purchasers or, in the case of
a waiver, by the party against whom enforcement of any such waived provision is sought, provided, however, that any proposed amendment or waiver that disproportionately, materially and adversely affects the rights and obligations of
any Purchaser relative to the comparable rights and obligations of the other Purchasers shall require the prior written consent of such adversely affected Purchaser. No waiver of any default with respect to any provision, condition or requirement of
this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right
hereunder in any manner impair the exercise of any such right. Any amendment effected in accordance with accordance with this Section 7.4 shall be binding upon each Purchaser and the Company. 

7.5 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit
or affect any of the provisions hereof. 
 7.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit
of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser. With the consent of the Company which will not be
unreasonably withheld, any Purchaser may assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Shares, provided, that a Purchaser may assign any or all rights under this Agreement
to an Affiliate of such Purchaser without the consent of the Company, and provided, further: (i) such transferor agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to
the Company after such assignment; (ii) the Company is furnished with written notice of (x) the name and address of such transferee or assignee and (y) if the transferor is assigning any registration rights under ARTICLE 5
hereof, the Registrable Securities with respect to which such registration rights are being transferred or assigned; (iii) following such transfer or assignment, the further disposition of such securities by the transferee or assignee is
restricted under the Securities Act and applicable state securities laws, unless such disposition was made pursuant to an effective registration statement or an exemption under Rule 144 under the Securities Act; (iv) such transferee agrees in
writing to be bound, with respect to the transferred Shares, by the provisions of the Transaction Documents that apply to the “Purchasers” including, without limitation, all of representations, warranties and agreements set forth in
ARTICLE 4 hereof; and (v) such transfer shall have been made in accordance with the applicable requirements of this Agreement and with all laws applicable thereto. 

 7.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the
parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Sections 5.4 and 6.4 and this
Section 7.7. In addition, the Placement Agent shall be an intended third party beneficiary of (i) the Company’s representations and warranties set forth in ARTICLE 3 hereof and (ii) each Purchaser’s
representations, warranties and agreements set forth in ARTICLE 4 hereof, including Section 4.8 hereof. 
 7.8
Governing Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the choice of law principles thereof. Each of the parties hereto irrevocably
submits to the exclusive jurisdiction of the state and federal courts located in the State of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby.
Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto
irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or
proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. If any party hereto shall commence an Action or Proceeding to enforce
any provisions of the Transaction Documents, then, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its reasonable attorneys’ fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such Action or Proceeding. 
 7.9 WAIVER OF JURY
TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY,
UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY. 
 7.10 Survival. The representations and warranties
contained herein shall survive the Closing and the delivery of the Shares. 
 7.11 Execution. This Agreement may be executed in two or
more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties
need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 

7.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall
use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be
the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 

7.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions
of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then
such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights. 

 7.14 Replacement of Shares. If any certificate or instrument evidencing any Shares is
mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument,
but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including
customary indemnity) associated with the issuance of such replacement Shares. 
 7.15 Remedies. In addition to being entitled to
exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a
remedy at law would be adequate. 
 7.16 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each
Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the
obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereof or thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any
other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. The Company has elected to
provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers.     

7.17 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares
of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof, each
reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event. 

7.18 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the
Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such
partial liquidated damages or other amounts are due and payable shall have been canceled. 
 7.19 Waiver of Conflicts. Each party to
this Agreement acknowledges that Cooley LLP (“Cooley”), outside general counsel to the Company, has in the past performed and is or may now or in the future represent one or more Purchasers or their affiliates in matters unrelated
to the transactions contemplated by this Agreement (the “Offering”), including representation of such Purchasers or their affiliates in matters of a similar nature to the Offering. The applicable rules of professional conduct
require that Cooley inform the parties hereunder of this representation and obtain their consent. Cooley has served as outside general counsel to the Company and has negotiated the terms of the Offering solely on behalf of the Company. The Company
and each Purchaser hereby (a) acknowledge that they have had an opportunity to ask for and have obtained information relevant to such representation, including disclosure of the reasonably foreseeable adverse consequences of such
representation; (b) acknowledge that with respect to the Offering, Cooley has represented solely the Company, and not any Purchaser or any stockholder, director or employee of the Company or any Purchaser; and (c) gives its informed
consent to Cooley’s representation of the Company in the Offering.

 EXHIBIT F 

PLAN OF DISTRIBUTION 
 We
are registering the shares of common stock issued to the selling stockholders to permit the resale of these shares of common stock by the selling stockholders from time to time from after the date of this prospectus. We will not receive any of the
proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock. 

Each selling stockholder may, from time to time, sell any or all of their shares of common stock covered hereby on The NASDAQ Global Market or
any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of
sale, or privately negotiated prices. A selling stockholder may use any one or more of the following methods when selling shares: 
  

	 	•	 	 ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

  

	 	•	 	 block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a
portion of the block as principal to facilitate the transaction; 

  

	 	•	 	 purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

 

	 	•	 	 an exchange distribution in accordance with the rules of the applicable exchange; 

 

	 	•	 	 privately negotiated transactions; 

 

	 	•	 	 settlement of short sales, to the extent permitted by law; 

 

	 	•	 	 in transactions through broker-dealers that agree with the selling stockholders to sell a specified number of
such shares at a stipulated price per share; 

  

	 	•	 	 through the writing or settlement of options or other hedging transactions, whether through an options exchange
or otherwise; 

  

	 	•	 	 a combination of any such methods of sale; or 

 

	 	•	 	 any other method permitted pursuant to applicable law. 

The selling stockholders may also sell the shares of common stock under Rule 144 under the Securities Act, if available, rather than under
this prospectus. 
 Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales.
Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this
prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440-1. 
 In connection with the sale of the shares of common
stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of common stock in the course of hedging the
positions they assume. The selling stockholders may also sell the shares of common stock short and deliver these securities to close out their short positions or to return borrowed shares in connection with such short sales, or loan or pledge the
shares of common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative
securities which require the delivery to such broker-dealer or other financial institution of shares of common stock offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus
(as supplemented or amended to reflect such transaction). 

 The selling stockholders and any broker-dealers or agents that are involved in selling the
shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such selling stockholders, broker-dealers or agents and any profit
on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act
will be subject to the prospectus delivery requirements of the Securities Act and may be subject to certain statutory liabilities of, including but not limited to, Sections 11, 12 and 17 of the Securities Act and Rule
10b-5 under the Exchange Act. Each selling stockholder has informed us that it is not a registered broker-dealer or an affiliate of a registered broker-dealer. In no event shall any broker-dealer receive fees,
commissions and markups which, in the aggregate, would exceed eight percent (8%). 
 We are required to pay certain fees and expenses
incurred by us incident to the registration of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act, and the selling stockholders may
be entitled to contribution. We may be indemnified by the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act that may arise from any written information furnished to us by the
selling stockholders specifically for use in this prospectus, or we may be entitled to contribution. 
 The selling stockholders will be
subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder unless an exemption therefrom is available. 

We agreed to cause the registration statement of which this prospectus is a part to remain effective until the earlier to occur of [•] or
the date on which all of the shares registered hereby are either sold pursuant to the registration statement or sold or available for resale without restriction under Rule 144 under the Securities Act. The shares of common stock will be sold only
through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the shares of common stock covered hereby may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification requirement is available and is complied with. 
 Under
applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the shares of common stock may not simultaneously engage in market making activities with respect to the shares of common stock for the applicable
restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including
Regulation M, which may limit the timing of purchases and sales of shares of common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the
need to deliver a copy of this prospectus at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act). 

There can be no assurance that any selling stockholder will sell any or all of the shares of common stock we registered on behalf of the
selling stockholders pursuant to the registration statement of which this prospectus forms a part. 
 Once sold under the registration
statement of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than our affiliates.
