Item 1.01.Entry into a Material Definitive Agreement


As previously disclosed, on January 11, 2021, ArcLight Clean Transition Corp., a Cayman Islands exempted company (“ArcLight”), entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among Phoenix Merger Sub, Inc., a Delaware corporation and a wholly-owned direct subsidiary of ArcLight (“Phoenix Merger Sub”), and Proterra Inc, a Delaware corporation (“Proterra”), with the transactions contemplated thereby referred to herein as the “Business Combination.”


Concurrently with the execution of the Merger Agreement, ArcLight CTC Holdings, L.P., a Delaware limited partnership (the “Sponsor”), entered into the Sponsor Letter Agreement (the “Sponsor Letter Agreement”) with ArcLight and Proterra, pursuant to which the Sponsor agreed, among other things, to be subject to a lock-up with respect to its shares of common stock, par value $0.0001 per share, of ArcLight immediately following the Business Combination (the “ArcLight Common Stock”) and its warrants to acquire such shares (collectively, the “Lock-up Shares”) for a period beginning on the date of closing of the Business Combination (the “Closing Date”) and ending 180 days after the Closing Date, or for such shorter period as the parties to the Sponsor Letter Agreement may mutually agree (the “Lock-up Period”).


On February 2, 2021, ArcLight, Proterra and the Sponsor entered into Amendment No. 1 to the Sponsor Letter Agreement (the “Amendment”) to conditionally shorten the Lock-up Period with respect to a portion of the Lock-up Shares based on the trading price of the ArcLight Common Stock following the Closing Date. Under the terms of the Amendment, the Lock-up Period shall be the period beginning on the Closing Date and ending 180 days after the Closing Date; provided, that the Lock-up Period will terminate early with respect to:


(A) 33% of the Lock-up Shares on the business day after the Release Condition (as defined below) is satisfied during the period starting on the day after the Closing Date and ending on the 119th day after the Closing Date; provided, that such early termination will occur no earlier than the later of 60 days after the Closing Date and 30 days after the registration statement registering shares of ArcLight Common Stock issued on the Closing Date to investors in connection with the PIPE financing contemplated by the Merger Agreement is declared effective under the Securities Act of 1933, as amended (the “Securities Act”), and


(B) 33% of the Lock-up Shares on the business day after the Release Condition is satisfied during the period starting 120 days after the Closing Date (which, for the avoidance of doubt, shall represent an additional 33% of the Lock-up Shares if the Release Condition shall have been satisfied in clause (A) above).


For purposes of the Amendment, the term “Release Condition” means if, over any 20 trading days within any 30 trading day period, the volume-weighted average price of ArcLight Common Stock is greater than or equal to $20.00 per share, or there occurs any transaction resulting in a change in control with a valuation for the ArcLight Common Stock that is greater than or equal to $20.00 per share; provided that the reference to $20.00 per share will be equitably adjusted on account of any changes occurring after the Closing Date in the equity securities of ArcLight by way of stock split, stock dividend, combination or reclassification, or through merger, consolidation, reorganization, recapitalization or business combination, or by any other means.


Under Proterra’s Ninth Amended and Restated Investors’ Rights Agreement (, the “IRA”), parties to the IRA agreed to be subject to a lock-up with respect to their outstanding shares of Proterra capital stock, including shares issuable upon exercise of outstanding warrants or conversion of outstanding secured convertible promissory notes, and the ArcLight Common Stock that will be issued in exchange for such shares of Proterra capital stock, for 180 days following the Closing Date, subject to customary terms and exceptions, which include a pro rata release provision. All of the parties to the IRA will be entitled to the benefit of the early lock-up release provisions of the Amendment with respect to such shares, which represent more than 95% of the currently outstanding shares of Proterra’s capital stock


A copy of the Amendment is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference, and the foregoing description of the Amendment is qualified in its entirety by reference thereto.
