 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

 3 













 (i) the Company’s chief executive officer (the

(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,

 4 













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

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

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.”

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

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,

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

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

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

 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

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

contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

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

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.”

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,

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:

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
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, Waveland Verdoso, Motorola or JKC 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. 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 

  
 9 













 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)(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 adjustment for any stock split,
reverse stock split or similar event), Section 1.2(a)(iv) of this Agreement shall not be amended or waived without the written consent of Investec so long as Investec 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), Section 1.2(a)(v) of this Agreement shall not be amended or waived without the written consent of Waveland, together with any WCP 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, 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 provision of this Section 3.5 can be amended without the required percentage vote of the beneficiary of that provision.

consideration upon the Approved Sale.” 
 e. The following Section 1.9 shall be added to the Voting Agreement:

limited to representations and warranties related to authority, ownership and the ability to convey title to the shares of capital stock of the Company held by such Investor or Key Holder (as the case may    













 
be), including, but not limited to, representations and warranties that (i) such Investor or Key Holder holds all right, title and interest in and to the shares of capital stock of the
Company such Investor or Key Holder (as the case may be) purports to hold, free and clear of all liens and encumbrances, (ii) the obligations of such Investor or Key Holder in connection with the transaction have been duly authorized, if
applicable, (iii) the documents to be entered into by such Investor or Key Holder have been duly executed by such Investor or Key Holder and delivered to the acquirer and are enforceable against such Investor or Key Holder in accordance with
their respective terms; and (iv) neither the execution and delivery of documents to be entered into in connection with the transaction, nor the performance of such Investor’s or Key Holder’s obligations thereunder, will cause a breach
or violation of the terms of any agreement, law or judgment, order or decree of any court or governmental agency; 

(b) such Investor or Key Holder shall not be liable for the inaccuracy of any representation or warranty made by any
other Person in connection with the Proposed Sale, other than the Company (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 as well as breach by any
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,
Waveland Verdoso or Motorola 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) or Motorola (or its affiliates), as the case may be. 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)(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
adjustment for any stock split, reverse stock split or similar event), Section 1.2(a)(iv) of this Agreement shall not be amended or waived without the written consent of Investec so long as Investec 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), Section 1.2(a)(v) of this Agreement shall not be amended or waived without the written consent of Waveland, together with any WCP
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. 

4. Amendment of the Co-Sale Agreement. The
Co-Sale Agreement is hereby amended so that, upon issuance of the Motorola Securities to Motorola: 

a. The introductory paragraph shall be amended to add the holders of Series A-1 Preferred Stock as
parties to the Co-Sale Agreement: 
 “This Amended and Restated Right of First Refusal and Co-Sale Agreement is made as of November 21, 2012 (the “Agreement”), by and among Sonim Technologies, Inc., a Delaware corporation (the “Company”), certain holders of the
Company’s Series A Preferred Stock (the “Series A Preferred”), certain holders of the Company’s Series A-1 Preferred Stock (the “Series A-1 Preferred”) and certain holders of the Company’s Series B Preferred Stock (the “Series B Preferred” and, together with the Series A Preferred and Series A-1 Preferred, the “Series Preferred”) listed on Exhibit A hereto (the “Major Investors”) and the holders of Common Stock and/or options to
purchase Common Stock listed on Exhibit B hereto (each a “Common Holder,” collectively, the “Common Holders”). Capitalized terms used but not defined herein shall have the meanings set forth in
that certain Preferred Stock Purchase and Exchange Agreement of even date herewith (the “Purchase Agreement”).” 

b. Section 4.10 shall be amended to add the following sentence at the end of Section 4.10: 

“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 Motorola without the written consent of Motorola 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 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
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.” 

c. Exhibit A to the Co-Sale Agreement shall be amended to add each New Investor that is a
“Major Investor” as defined in the Rights Agreement as a “Major Investor” thereunder. 
 5. This Amendment may be
executed in counterparts, each of which shall be an original, and all of which, when taken together, shall constitute one and the same instrument. 

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. 
 8. If one or
more provisions of this Amendment are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such
provision, the (i) such provision shall be excluded from this Amendment, (ii) the balance of the Amendment shall be interpreted as if such provision were so excluded and (iii) the balance of the Amendment shall be enforceable in
accordance with its terms. 
 9. This Amendment and all acts and transactions pursuant hereto and the rights and obligations of the parties
hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law.

shares under the Securities Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144, except in unusual circumstances. After its Initial Offering, the Company will not require the transferee
to be bound by the terms of this Agreement. 
 (b) Notwithstanding the provisions of subsection (a) above, no such restriction

REQUIRED. 

  
 4 













 THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS
CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN INVESTOR RIGHTS AGREEMENT BY AND BETWEEN THE STOCKHOLDER AND THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY. 

(d) The Company shall be obligated to reissue promptly unlegended certificates at the request of any Holder thereof if the Company has
completed its Initial Offering and the Holder shall have obtained an opinion of counsel (which counsel may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be
so disposed of without registration, qualification and legend. 
 (e) Any legend endorsed on an instrument pursuant to applicable
state securities laws and the stop-transfer instructions with respect to such securities shall be removed upon receipt by the Company of an order of the appropriate blue sky authority authorizing such removal. 

2.2 Demand Registration. 

(a) Subject to the conditions of this Section 2.2, if the Company shall receive a written request from the Holders of at least
forty percent (40%) of the Registrable Securities (the “Initiating Holders”) that the Company file a registration statement under the Securities Act covering the registration of the Registrable Securities then outstanding
with an anticipated aggregate offering price, net of underwriting discounts and commissions, of at least $7,500,000 (a “Qualified Public Offering”), then the Company shall, within thirty (30) days of the receipt thereof,
give written notice of such request to all Holders, and subject to the limitations of this Section 2.2, use commercially reasonable efforts to effect, as expeditiously as reasonably possible, the registration under the Securities Act of all
Registrable Securities that all Holders request to be registered. 
 (b) If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2.2 or any request pursuant to Section 2.4 and the Company shall include
such information in the written notice referred to in Section 2.2(a) or Section 2.4(a), as applicable. In such event, the right of any Holder to include its Registrable 

  
 5 













 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
in customary form with the underwriter or underwriters selected for such underwriting by a majority in interest of the Initiating Holders (which underwriter or underwriters shall be reasonably acceptable to the Company and a majority in interest of
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.

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

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.

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.

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;

all shares of capital stock reserved for future issuance) issued pursuant to any equipment loan or leasing arrangement, real property leasing arrangement or debt financing from a 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;

outstanding shares of Preferred Stock will convert into shares of Common Stock under the terms of the Company’s Certificate of incorporation, as amended from time to time; 

(h) any Equity Securities issued by the Company pursuant to the terms of Section 1 of the Purchase Agreement or the
Restated LSA and all warrants exercisable for shares of Series A Preferred and Series B Preferred (and the shares of Series A Preferred and Series B Preferred, as applicable, issued upon exercise of such warrants and all shares of Common Stock
issued upon conversion thereof) that are outstanding on the date hereof; and 
 (i) any Equity Securities issued to Investec in
connection with loans that may be provided to the Company by Investec, provided that the terms of such loans and such issuances of Equity Securities are approved by the Board of Directors.
