Ladies and Gentlemen:
Reference is made herein to that certain License and Integration Agreement, dated as of August 10, 2018, by and among Uber Technologies, Inc., a Delaware corporation (“UTI”), Neutron Holdings, Inc., DBA “Lime”, a Delaware corporation (the “Company”), and the other parties thereto (as amended to date and as may be further amended and/or restated, the “License and Integration Agreement”). In connection with the execution of Amendment 10 to the License and Integration Agreement, dated as of the date hereof, UTI and the Company hereby agree to the terms and obligations of this letter agreement (this “Letter Agreement”). Reference is made herein to that certain Investors’ Rights Agreement, dated as of May 7, 2020, by and among the Company, UTI and the other parties thereto (as may be amended and/or restated from time to time, the “Rights Agreement”). Capitalized terms used but not defined herein shall have the meanings given to them in the Rights Agreement.
1.    Additional “Market Stand-off” Agreement. Following the expiration of the restrictions contained in Section 2.11 of the Rights Agreement with respect to the IPO (the “Rights Agreement Lockup Period”), the following additional restrictions shall apply to UTI.

i.IPO Date” means the date of the final prospectus relating to the IPO.
ii.Lockup Securities” means any shares of Common Stock or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock held by UTI immediately before the IPO Date.

(b)    Lock-up Periods. UTI hereby agrees that it will not, without the prior written consent of the Company:
(x)during the period commencing on the expiration of the Rights Agreement Lockup Period and ending on the date that is one (1) year following the IPO Date (the “First Lockup Date”), conduct any Restricted Activities;
(y)during the period commencing on the day after the First Lockup Date and ending on the date that is eighteen (18) months following the IPO Date (the “Second Lockup Date”), conduct any Restricted Activities other than Restricted Activities with respect to up to twenty-five percent (25%) of the Lockup Securities, in the aggregate; and

(c)    Exceptions to Lock-up. For clarity, nothing in this Letter Agreement shall restrict UTI’s ability to conduct Restricted Activities after the date that is two (2) years following the IPO Date. Further, the provisions of Section 1(b) shall not apply to (i) the sale of any shares to an underwriter pursuant to an underwriting agreement, (ii) the transfer of Lockup Securities by UTI to an Affiliate of UTI, provided that such transferee agrees to be bound by substantially similar restrictions to those contained in this Letter Agreement, or (iii) the transfer of Lockup Securities in connection with a bona fide third-party tender offer, merger, consolidation or other similar transaction, that is approved by the Board of Directors, made to all holders of Common Stock involving a Change of Control (as defined below), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Lockup Securities owned by UTI shall remain subject to the restrictions contained in this Letter Agreement. For the purposes of this Section 1(c), “Change of Control” means the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons (other than any underwriters in a public offering), of shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock if, after such transfer, the stockholders of the Company immediately prior to such transfer do not own at least fifty percent (50%) of the outstanding voting securities of the Company (or the surviving entity).
2.    Miscellaneous.

This Letter Agreement shall terminate and be of no further force or effect upon the earliest to occur of: (i) the date that is two (2) years following the IPO Date, (ii) the termination of the License and Integration Agreement or (iii) immediately prior to the closing of a Deemed Liquidation Event (as defined in the Company’s Ninth Amended and Restated Certificate of Incorporation (as may be amended and/or restated from time to time)).
(b)    Amendments and Waivers. This Letter Agreement may not be amended or modified, or any provision hereof waived, without the written consent of the Company and UTI.
