Following a Public Company Event, subject to the continued satisfaction of the Board Nomination Conditions, the Company shall, and shall cause the Public Company Event Board of Directors (or the nominating committee thereof) to, (i) nominate one BMW Designee to the initial post-Public Company Event Board of Directors (which shall be a classified board with three classes, and the BMW Designee shall be in the class that is last up for re-election following the Public Company Event at the third annual meeting of stockholders following the Public Company Event), (ii) include any such designee in the slate of nominees recommended to the applicable stockholders for reelection at each applicable annual meeting of stockholders held on or before the Nomination Right Sunset Date, and (iii) ensure that any BMW Designee up for election is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of Public Company Event Board of Directors, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or Public Company Event Board of Directors with respect to the election of members of Public Company Event Board of Directors prior to the Nomination Right Sunset Date. In the event that BMW shall desire to appoint a BMW Designee other than in connection with a stockholder solicitation or action relating to the election of directors, then as soon as practicable upon written notice from BMW, but in no event in more than ten (10) days from such notice, the Public Company Event Board of Directors shall appoint the BMW Designee to the Public Company Event Board of Directors.

Notwithstanding the foregoing, BMW shall not be entitled to designate a particular BMW Designee if (i) there has been a failure by such BMW Designee to materially comply with the Confidentiality guidelines set out in Section 1 of the Governance Guidelines or the Conflict of Interest guidelines set out in Section 2 of the Governance Guidelines, as determined by Independent Counsel, or (ii) Independent Counsel determines that such BMW Designee is not qualified to serve as a director of the Company under any then applicable law (including requirements of fiduciary duties under applicable law), rule or regulation, or any applicable rule of the stock exchange on which the Company’s shares are listed; provided that, any BMW Designee that does not qualify as “Independent” as defined in the listing standards of the applicable securities exchange rules due to the failure to satisfy such requirements or any other rules relating to diversity and inclusion or similar requirements shall not be deemed a failure to qualify to serve as a director for purposes of this Agreement. The Company shall notify BMW as soon as reasonably practicable of any objection to any particular BMW Designee as to enable BMW to propose a replacement designee. Notwithstanding anything to the contrary herein, the director position for such BMW Designee shall not be filled pending such proposal and appointment or election of a BMW Designee.

2.3 Voting of Management Shares. Following a Public Company Event, the Company shall endeavor, using commercially reasonable efforts, (i) to cause the shares held by the Company’s executive officers that are not Key Holders hereunder on the date hereof (“Future Executives”) to be voted in favor of the election of the BMW Designee nominated pursuant to this Agreement; (ii) to cause each such Future Executive to become a party to this Agreement as a Key Holder by executing a joinder to this agreement, and (iii) to cause the Public Company Event Board of Directors to recommend to its stockholders to vote in favor of the BMW Designee for election to the Public Company Event Board of Directors.

2.4 Vacancies. In the event that any BMW Designee shall cease to serve as a director of the Public Company Event Board of Directors for any reason during a period in which BMW’s designation rights pursuant to Section 2.1 hereof apply, the vacancy resulting therefrom shall be filled only by another BMW Designee, subject to the conditions and qualifications above. Notwithstanding anything to the contrary herein, the Public Company Event Board of Directors shall take no action to fill the director position for such BMW Designee until BMW makes such designation.

2.5 Indemnification. The Company shall indemnify the BMW Designee on the same basis as all other members of the Board and pursuant to an indemnity agreement with terms that are no less favorable to the BMW Designee than the indemnity agreements entered into between the Company and its other directors.

2.6 Compensation and Expenses. The Company shall reimburse the BMW Designee in accordance with the Company’s expense reimbursement policies applicable to outside directors.

2.7 Negative Covenant. The Company shall not decrease the size of the Board so as to eliminate directorships sufficient for the BMW Designee to serve on the Board, or to otherwise circumvent the purpose of, or the Company’s obligations under, this Agreement.

2.8 Designation of Proxy. Each of the Key Holders hereto hereby constitutes and appoints the President and Secretary of the Company or the SPAC, as applicable, and each of them, with full power of substitution, as its proxies to represent and to vote all of such Key Holder’s voting securities in accordance with the terms and provisions of this Agreement, if and only if such Key Holder (i) fails to vote or (ii) attempts to vote (whether by proxy, in person or by written consent) in a manner that is inconsistent with the terms of this Agreement. The proxy granted pursuant to the immediately preceding sentence is given in consideration of the agreements and covenants of the Company and the parties hereto in connection with the transactions contemplated by this Agreement and, as such, is coupled with an interest and shall be irrevocable unless and until this Agreement terminates or expires.

3. Miscellaneous
