NOW, THEREFORE, in consideration of the foregoing premises and certain other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Parties agree as follows: 
 1. Agreement to Vote. Each Investor, as a holder of Preferred Stock,
hereby agrees on behalf of itself and any transferee or assignee of any such shares of the Preferred Stock (and any securities of the Company issued with respect to, upon conversion of, or in exchange or substitution of the Preferred Stock, and any
other voting securities of the Company subsequently acquired by such Investor) (collectively the “Investor Shares”), to vote the Investor Shares at a regular or special meeting of stockholders (or by written consent) in accordance with,
the provisions of this Agreement. Each Common Holder, as a holder of Common Stock , hereby agrees on behalf of itself and any transferee or assignee of any such shares of Common Stock, and any other securities of the Company acquired by such Common
Holder in the future (and any securities of the Company issued with respect to, upon conversion of, or in exchange or substitution for such securities) (collectively, the “Common Holder Shares” and together with the Investor Shares, the
“Shares”) subject to, and to vote the Common Holder Shares at a regular or special meeting of stockholders (or by written consent) in accordance with, the provisions of this Agreement. 

2. Board Size. The holders of Investor Shares and Common Holder Shares shall vote at a regular or special meeting of stockholders (or by
written consent) such shares that they own (or as to which they have voting power) to ensure that the size of the Board shall be set and remain at five (5) directors; provided, however, that such Board size may be subsequently increased by one
(1) pursuant to Hitachi’s election of a director of the Company under Section 3(d) hereof or subsequently increased or decreased pursuant to an amendment of this Agreement in accordance with Section 15 hereof. 

3. Election of Directors. 

(a) In any election of directors of the Company to elect the Common Director, the Parties shall each vote at any regular or special meeting of
stockholders (or by written consent) such number of Shares then owned by them (or as to which they then have voting power) as may be necessary to elect one (1) director nominated by the Common Holders holding a majority of the Common Holder

 (b) For so long as at least 25% of the Voting Preferred Stock remains outstanding, in any
election of directors of the Company to elect the Voting Preferred Stock Director, the Parties shall each vote at any regular or special meeting of the stockholders (or by written consent) such number of Shares then owned by them (or to which they
then have voting power) as may be necessary to elect one (1) director nominated by the Series A Investors, Series B Investors and Series D Investors holding a majority such Investor Shares. The Voting Preferred Stock Director shall initially be
Stephen Aldous. 
 (c) For so long as at least 25% of the Series C Preferred Stock remains outstanding, in any election of directors of the
Company to elect the Series C Director, the Parties shall each vote at any regular or special meeting of the stockholders (or by written consent) such number of Shares then owned by them (or to which they then have voting power) as may be necessary

of the Company to elect the Hitachi Director, the Parties shall each vote at any regular or special meeting of the stockholders (or by written consent) such number of Shares then owned by them (or to which they then have voting power) as may be
necessary to elect one (1) director nominated by Hitachi. Notwithstanding anything to the contrary herein, if Hitachi has not nominated a person to be a director of the Company, Hitachi may instead elect a representative to attend and
participate fully in all meetings of the Board in a nonvoting observer capacity, and the Board shall give the observer copies of all minutes, notices, consents and other material that it gives to the directors. 

4. Failure to Designate; Removal. In the absence of a designation from the stockholders with the right to designate a director as
specified in Section 3, the director previously designated by them and then serving shall be reelected if still eligible to serve as provided herein. Any director of the Company may be removed from the Board in the manner allowed by law and the
Certificate of Incorporation and Bylaws, but with respect to a director designated pursuant to Section 3, only upon the vote or written consent of the stockholder(s) entitled to designate such director. Notwithstanding the foregoing, in the
event that the Common Director shall cease to serve as the chief executive officer (or president, as the case may be) of the Company, each of the Parties shall vote all of their Common Stock or other voting securities (i) to remove the former
Common Director from the Board if such person has not resigned as a member of the Board and (ii) to elect such person’s replacement as the Company’s chief executive officer (or president, if none) as the new Common Director. 

5. Legend on Share Certificates. Each certificate representing any Shares shall be endorsed by the Company with a legend reading
substantially as follows:

WRITTEN REQUEST FROM THE ISSUER), AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SAID VOTING AGREEMENT.”

 6. Covenants of the Company. The Company agrees to use its diligent efforts to ensure that
the rights granted hereunder are effective and that the Parties hereto enjoy the benefits thereof. Such actions include, without limitation, the use of the Company’s diligent efforts to cause the nomination and election of the directors as
provided above. The Company will not, by any voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all
of the provisions of this Agreement. 
 7. No Liability for Election of Recommended Directors. Neither the Company, the Common
Holders, the Investors, nor any officer, director, stockholder, partner, employee or agent of such Party, makes any representation or warranty as to the fitness or competence of the nominee of any Party hereunder to serve on the Board by virtue of
such Party’s execution of this Agreement or by the act of such Party in voting for such nominee pursuant to this Agreement. 
 8.
Irrevocable Proxy. To secure the Common Holders’ and the Investors’ obligations to vote the Common Holder Shares and the Investor Shares in accordance with this Agreement, each Common Holder and each Investor hereby appoints a
stockholder designated by the Board as such Common Holder’s or Investor’s true and lawful proxy and attorney, with the power to act alone and with full power of substitution, to vote all of such Common Holder’s Common Holder Shares or
such Investor’s Investor Shares as set forth in this Agreement and to execute all appropriate instruments consistent with this Agreement on behalf of such Common Holder or Investor if, and only if, such Common Holder or Investor fails to vote
all of such Common Holder’s Common Holder Shares or such Investor’s Investor Shares or execute such other instruments in accordance with the provisions of this Agreement within five days of the Company’s or any other party’s
written request for such Common Holder’s or Investor’s written consent or signature. The proxy and power granted by each Common Holder and Investor pursuant to this Section 8 are coupled with an interest and are given to secure the
performance of such party’s duties under this Agreement. Each such proxy and power will be irrevocable for the term hereof. The proxy and power, so long as any party hereto is an individual, will survive the death, incapacity and disability of
such party or any other individual holder of Investor Shares or Common Holder Shares and, so long as any party hereto is an entity, will survive the merger or reorganization of such party or any other entity holding any Investor Shares or Common
Holder Shares. 
 9. Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an
injured Party for the breach of this Agreement by any Party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or

the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.
