Amended and Restated Warrant Agreement among Proterra Inc, Computershare Inc. and Computershare Trust Company, N.A., dated June 14, 2021

THIS AMENDED AND RESTATED WARRANT AGREEMENT (this “Agreement”), dated June 14, 2021, is by and among Proterra Inc, a Delaware corporation (the “Company”), Computershare Inc., a Delaware corporation, and its wholly-owned subsidiary, Computershare Trust Company, N.A., a federally chartered trust company, collectively as Warrant Agent (the “Warrant Agent”) (each a “Party” and collectively, the “Parties”).

WHEREAS, the Company (then known as ArcLight Clean Transition Corp., a Cayman Islands exempted company (“ACTC”)) previously entered into the Warrant Agreement, dated September 25, 2020 (the “Original Agreement”), with Continental Stock Transfer & Trust Company; and

WHEREAS, pursuant to the Agreement and Plan of Merger Agreement, dated as of January 11, 2021 (as amended, restated or otherwise modified from time to time, the “Merger Agreement”), by and among ACTC, Phoenix Merger Sub, Inc. and Proterra Inc, the parties thereto consummated a business combination (the “Business Combination”), which included the domestication of ACTC in Delaware as “Proterra Inc” (the “Domestication”), in accordance with the terms and conditions of the Merger Agreement and applicable law; and

WHEREAS, as of immediately prior to the Domestication, ACTC had outstanding: (i) certain redeemable warrants (the “Public Warrants”) to purchase Class A ordinary shares of ACTC that were registered pursuant to ACTC’s initial public offering registration statement and offered by ACTC in its initial public offering of units of ACTC’s equity securities (the “Units”), each such unit comprised of one Class A ordinary share of ACTC and one-half of a Public Warrant; and (ii) 7,550,000 warrants to purchase Class A ordinary shares of ACTC that were issued in a private placement concurrently with ACTC’s initial public offering (the “Private Placement Warrants” and, together with the Public Warrants, the “Warrants”); and

WHEREAS, in connection with the Domestication, (i) the Class A ordinary shares of ACTC converted into shares of common stock of the Company, par value $0.00001 per share (“Common Shares”), and (ii) the Private Placement Warrants and the Public Warrants automatically converted by operation of law into warrants to acquire Common Shares; and

WHEREAS, at a moment in time after effectiveness of the Domestication and before the closing of the Business Combination, each outstanding Unit separated into its component Common Share and Public Warrant; and

WHEREAS, each Warrant entitles the holder thereof to purchase one Common Share, for $11.50 per share, subject to adjustment as described herein. Only whole Warrants are exercisable. A holder of Public Warrants will not be able to exercise any fraction of a Warrant; and

WHEREAS, the Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-4, File No. 333-252674 and a proxy statement/prospectus (the “Registration Statement”), for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the Public Warrants, the Private Placement Warrants and the Common Shares issuable upon exercise of the Public Warrants and the Private Placement Warrants; and

WHEREAS, the Private Placements Warrants are subject to certain transfer restrictions and shall bear the legend set forth in Exhibit B hereto;

WHEREAS, in connection with the Business Combination, the Company and the Warrant Agent desire to amend and restate the Original Agreement to substitute the warrant agent hereunder; and

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent and the holders of the Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent (if a physical certificate is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1.Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement.

2.Warrants.

2.1.Form of Warrant. Each Warrant shall initially be issued in registered form only.

2.2.Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

2.3.Registration.

2.3.1.Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Public Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have accounts with The Depository Trust Company (the “Depositary”) (such institution, with respect to a Warrant in its account, a “Participant”).

If the Depositary subsequently ceases to make its book-entry settlement system available for the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical form evidencing such Warrants (“Definitive Warrant Certificates”) which shall be in the form annexed hereto as Exhibit A.

Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the President, Chief Executive Officer, any Vice President, Treasurer or Chief Financial Officer, Secretary, Clerk or Director of Stock Administration of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

2.3.2.Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such

Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby, for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2.4.Detachability of Warrants. [Reserved].

2.5.Fractional Warrants. Other than in connection with the Domestication, the Company shall not issue fractional Warrants. If a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down to the nearest whole number the number of Warrants to be issued to such holder.

2.6.Private Placement Warrants. The Private Placement Warrants shall be identical to the Public Warrants, except that so long as they are held by ArcLight CTC Holdings, L.P., a Delaware limited partnership (the “Sponsor”), or any of its Permitted Transferees (as defined below) the Private Placement Warrants: (i) may be exercised for cash or on a “cashless basis,” pursuant to subsection 3.3.1(c) hereof, (ii) including the Common Shares issuable upon exercise of the Private Placement Warrants, may not be transferred, assigned or sold until July 14, 2021, (iii) shall not be redeemable by the Company pursuant to Section 6.1 hereof and (iv) shall only be redeemable by the Company pursuant to Section 6.2 if the Reference Value (as defined below) is less than $18.00 per share (subject to adjustment in compliance with Section 4 hereof); provided, however, that in the case of (ii), the Private Placement Warrants and any Common Shares issued upon exercise of the Private Placement Warrants may be transferred by the holders thereof:

(a)to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates;

(b)in the case of an individual, by gift to a member of one of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization;

(c)in the case of an individual, by virtue of laws of descent and distribution upon death of the individual;

(d)in the case of an individual, pursuant to a qualified domestic relations order;

(e)[Reserved];

(f)by virtue of the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor;

(g)[Reserved];

(h)[Reserved]; or

(i)in the event of the Company’s completion of a liquidation, merger, share exchange or other similar transaction which results in all of the public shareholders having the right to exchange their Common Shares for cash, securities or other property;

provided, however, that, in the case of clauses (a) through (f), these permitted transferees (the “Permitted Transferees”) must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement.

3.Terms and Exercise of Warrants.

3.1.Warrant Price. Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of Common Shares stated therein, at the price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share (including in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent permitted hereunder) described in the prior sentence at which Common Shares may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than fifteen Business Days (as defined below) (unless otherwise required by the Commission, any national securities exchange on which the Warrants are listed or applicable law); provided that the Company shall provide at least five days’ prior written notice of such reduction to Registered Holders of the Warrants; and provided further, that any such reduction shall be identical among all of the Warrants. For the purposes of this Agreement, a “Business Day” shall mean a day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business.

3.2.Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) (A) commencing on September 25, 2021, and (B) terminating at the earliest to occur of (x) 5:00 p.m., New York City time on June 14, 2026, , and (y) other than with respect to the Private Placement Warrants then held by the Sponsor or its Permitted Transferees with respect to a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), Section 6.2 hereof, 5:00 p.m., New York City time on the Redemption Date (as defined below) as provided in Section 6.3 hereof (the “Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below, with respect to an effective registration statement or a valid exemption therefrom being available. Except with respect to the right to receive the Redemption Price (as defined below) (other than with respect to a Private Placement Warrant then held by the Sponsor or its Permitted Transferees in connection with a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), Section 6.2 hereof) in the event of a redemption (as set forth in Section 6 hereof), each Warrant (other than a Private Placement Warrant then held by the Sponsor or its Permitted Transferees in the event of a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), Section 6.2 hereof) not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders

of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.

3.3.Exercise of Warrants.

3.3.1.Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof by delivering to the Warrant Agent at its office designated for such purpose (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Warrant represented by a book-entry, the Warrants to be exercised (the “Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from time to time, (ii) an election to purchase (“Election to Purchase”) any Common Shares pursuant to the exercise of a Warrant, properly completed and executed with signature properly guaranteed by the Registered Holder on the reverse of the Definitive Warrant Certificate or, in the case of a Book-Entry Warrant, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) the payment in full of the Warrant Price for each Common Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Common Shares and the issuance of such Common Shares, as follows:

(a)in lawful money of the United States, in good certified check or wire payable to the Warrant Agent;

(b)with respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or a Permitted Transferee, by surrendering the Warrants for that number of Common Shares equal to (i) if in connection with a redemption of Private Placement Warrants pursuant to Section 6.2 hereof, as provided in Section 6.2 hereof with respect to a Make-Whole Exercise and (ii) in all other scenarios the quotient obtained by dividing (x) the product of the number of Common Shares underlying the Warrants, multiplied by the excess of the “Sponsor Exercise Fair Market Value” (as defined in this subsection 3.3.1(c)) less the Warrant Price by (y) ACTC Exercise Fair Market Value. Solely for purposes of this subsection 3.3.1(c), the “Sponsor Fair Market Value” shall mean the average last reported sale price of the Common Shares for the ten (10) trading days ending on the third (3rd) trading day prior to the date on which notice of exercise of the Private Placement Warrant is sent to the Warrant Agent;

(c)as provided in Section 6.2 hereof with respect to a Make-Whole Exercise; or

(d)as provided in Section 7.4 hereof.

3.3.2.Issuance of Common Shares on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of Common Shares to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it on the register of members of the Company, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any Common Shares pursuant to the exercise of a Warrant and

shall have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act with respect to the Common Shares underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4 or a valid exemption from registration is available. No Warrant shall be exercisable and the Company shall not be obligated to issue Common Shares upon exercise of a Warrant unless the Common Shares issuable upon such Warrant exercise have been registered, qualified or deemed to be exempt from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Warrants. Subject to Section 4.6 of this Agreement, a Registered Holder of Warrants may exercise its Warrants only for a whole number of Common Shares. The Company may require holders of Public Warrants to settle the Warrant on a “cashless basis” pursuant to Section 7.4. If, by reason of any exercise of Warrants on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a Common Share, the Company shall round down to the nearest whole number, the number of Common Shares to be issued to such holder.

3.3.3.Valid Issuance. All Common Shares issued upon the proper exercise of a Warrant in conformity with this Agreement and the certificate of incorporate and bylaws of the Company shall be validly issued, fully paid and nonassessable.

The Company shall provide an opinion of counsel which shall state that all Warrants or Common Shares, as applicable, are: registered under the Securities Act, or are exempt from such registration, and validly issued, fully paid and non-assessable.

3.3.4.Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for Common Shares is issued and who is registered in the register of members of the Company shall for all purposes be deemed to have become the holder of record of such Common Shares on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the register of members of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the share transfer books or book-entry system are open.

3.3.5.Maximum Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the Common Shares outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of Common Shares beneficially owned by such person and its affiliates shall include the number of Common Shares issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude Common Shares that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person and its

affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in determining the number of outstanding Common Shares, the holder may rely on the number of outstanding Common Shares as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or Computershare Trust Company, N.A., as transfer agent (in such capacity, the “Transfer Agent”), setting forth the number of Common Shares outstanding. For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of Common Shares then outstanding. In any case, the number of issued and outstanding Common Shares shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of issued and outstanding Common Shares was reported. By written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

3.3.6.In connection with any exercise of Warrants on a “cashless basis” hereunder, the Company shall calculate and transmit to the Warrant Agent with reasonable written notice, and the Warrant Agent shall have no obligation under this Agreement to calculate, any formula for any exercises of Warrants on a “cashless basis.” The number of Common Shares to be issued on such exercise will be determined by the Company (with reasonable written notice thereof to the Warrant Agent), and the Warrant Agent shall have no duty or obligation to investigate or confirm whether the Company’s determination of the number of Common Shares to be issued on such exercise, pursuant to this Section 3.3.6, is accurate or correct.

4.Adjustments.

4.1.Share Capitalizations.

4.1.1.Sub-Divisions. If after the date hereof, and subject to the provisions of Section 4.6 below, the number of issued and outstanding Common Shares is increased by a capitalization or share dividend of Common Shares, or by a sub-division of Common Shares or other similar event, then, on the effective date of such share capitalization, sub-division or similar event, the number of Common Shares issuable on exercise of each Warrant shall be increased in proportion to such increase in the issued and outstanding Common Shares. A rights offering made to all or substantially all holders of Common Shares entitling holders to purchase Common Shares at a price less than the Historical Fair Market Value (as defined below) shall be deemed a capitalization of a number of Common Shares equal to the product of (i) the number of Common Shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for the Common Shares) multiplied

by (ii) one (1) minus the quotient of (x) the price per Common Share paid in such rights offering divided by (y) the Historical Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Common Shares, in determining the price payable for Common Shares, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Historical Fair Market Value” means the volume weighted average price of the Common Shares during the ten (10) trading day period ending on the trading day prior to the first date on which the Common Shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights. No Common Shares shall be issued at less than their par value.

4.1.2.Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, pays to all or substantially all of the holders of the Common Shares a dividend or make a distribution in cash, securities or other assets on account of such Common Shares (or other shares into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), or (c) to satisfy the redemption rights of the holders of the Common Shares in connection with the Business Combination, (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Company’s board of directors (the “Board”), in good faith) of any securities or other assets paid on each Common Share in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Shares during the 365-day period ending on the date of declaration of such dividend or distribution to the extent it does not exceed $0.50 (which amount shall be adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of Common Shares issuable on exercise of each Warrant).

4.2.Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of issued and outstanding Common Shares is decreased by a consolidation, combination, or reclassification of Common Shares or other similar event, then, on the effective date of such consolidation, combination, reclassification or similar event, the number of Common Shares issuable on exercise of each Warrant shall be decreased in proportion to such decrease in issued and outstanding Common Shares.

4.3.Adjustments in Exercise Price. Whenever the number of Common Shares purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of Common Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of Common Shares so purchasable immediately thereafter.

4.4.Raising of the Capital in Connection with the Initial Business Combination. [Reserved].

4.5.Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding Common Shares (other than a change under Section 4.1 or Section 4.2 hereof or that solely affects the par value of such Common Shares), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the issued and outstanding Common Shares), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the Common Shares of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance”); provided, however, that (i) if the holders of the Common Shares were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of the Common Shares in such consolidation or merger that affirmatively make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted by the holders of the Common Shares under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the issued and outstanding Common Shares, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of cash, securities or other property to which such holder would actually have been entitled as a shareholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Common Shares held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in this Section 4; provided further that if less than 70% of the consideration receivable by the holders of the Common Shares in the applicable event is payable in the form of shares in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the Black-

Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets (assuming zero dividends) (“Bloomberg”). For purposes of calculating such amount, (i) Section 6 of this Agreement shall be taken into account, (ii) the price of each Common Share shall be the volume weighted average price of the Common Shares during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (iii) the assumed volatility shall be the 90 day volatility obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event and (iv) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the Common Shares consists exclusively of cash, the amount of such cash per Common Share, and (ii) in all other cases, the volume weighted average price of the Common Shares during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in Common Shares covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event shall the Warrant Price be reduced to less than the par value per share issuable upon exercise of such Warrant.

4.6.Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give reasonable written notice thereof to the Warrant Agent, which notice shall state any new or amended exercise terms, including the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. The Warrant Agent shall have no obligation under any section of this Agreement to determine whether an event requiring such adjustment has occurred or to calculate any of the adjustments set forth herein. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3, 4.4 or 4.5, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.7.No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of Common Shares to be issued to such holder.

4.8.Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make

any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

5.Transfer and Exchange of Warrants.

5.1.Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

5.2.Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except as otherwise provided herein or with respect to any Book-Entry Warrant, each Book-Entry Warrant may be transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor depository, or to a nominee of a successor depository; provided further, however that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.

5.3.Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant.

5.4.Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

5.5.Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign by manual, electronic or facsimile signature and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

5.6.Transfer of Warrants. [Reserved].

6.Redemption.

6.1.Redemption of Warrants for Cash. Subject to Section 6.5 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below, at a Redemption Price of $0.01 per Warrant, provided that (a) the Reference Value equals or exceeds $18.00 per share (subject to adjustment

in compliance with Section 4 hereof) and (b) there is an effective registration statement covering the issuance of the Common Shares issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.3 below).

6.2.Redemption of Warrants for Common Shares. Subject to Section 6.5 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below, at a Redemption Price of $0.10 per Warrant, provided that (i) the Reference Value equals or exceeds $10.00 per share (subject to adjustment in compliance with Section 4 hereof) and (ii) if the Reference Value is less than $18.00 per share (subject to adjustment in compliance with Section 4 hereof), the Private Placement Warrants are also concurrently called for redemption on the same terms as the outstanding Public Warrants. During the 30-day Redemption Period in connection with a redemption pursuant to this Section 6.2, Registered Holders of the Warrants may elect to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1 and receive a number of Common Shares determined by reference to the table below, based on the Redemption Date (calculated for purposes of the table as the period to expiration of the Warrants) and the Redemption Fair Market Value (as such term is defined in this Section 6.2) (a “Make-Whole Exercise”). Solely for purposes of this Section 6.2, the “Redemption Fair Market Value” shall mean the volume weighted average price of the Common Shares for the ten (10) trading days immediately following the date on which notice of redemption pursuant to this Section 6.2 is sent to the Registered Holders. In connection with any redemption pursuant to this Section 6.2, the

Company shall provide the Registered Holders with the Redemption Fair Market Value no later than one (1) Business Day after the ten (10) trading day period described above ends.

The exact Redemption Fair Market Value and Redemption Date may not be set forth in the table above, in which case, if the Redemption Fair Market Value is between two values in the table or the Redemption Date is between two redemption dates in the table, the number of Common Shares to be issued for each Warrant exercised in a Make-Whole Exercise shall be determined by a straight-line interpolation between the number of shares set forth for the higher and lower Redemption Fair Market Values and the earlier and later redemption dates, as applicable, based on a 365- or 366-day year, as applicable.

The share prices set forth in the column headings of the table above shall be adjusted as of any date on which the number of shares issuable upon exercise of a Warrant or the Warrant Price is adjusted pursuant to Section 4 hereof. If the number of shares issuable upon exercise of a Warrant is adjusted pursuant to Section 4 hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment, multiplied by

a fraction, the numerator of which is the number of shares deliverable upon exercise of a Warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Warrant as so adjusted. The number of shares in the table above shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Warrant. If the Warrant Price of a warrant is adjusted pursuant to Section 4.1.2

hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment less the decrease in the Warrant Price pursuant to such Warrant Price adjustment. In no event shall the number of shares issued in connection with a Make-Whole Exercise exceed 0.361 Common Shares per Warrant (subject to adjustment)

6.3.Date Fixed for, and Notice of, Redemption; Redemption Price; Reference Value. In the event that the Company elects to redeem the Warrants pursuant to Sections 6.1 or 6.2, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the “30-day Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice. As used in this Agreement, (a) “Redemption Price” shall mean the price per Warrant at which any Warrants are redeemed pursuant to Sections 6.1 or 6.2 and (b) “Reference Value” shall mean the last reported sales price of the Common Shares for any twenty (20) trading days within the thirty (30) trading-day period ending on the third trading day prior to the date on which notice of the redemption is given.

6.4.Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with Section 6.2 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.3 hereof and prior to the Redemption Date. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

6.5.Exclusion of Private Placement Warrants. The Company agrees that (a) the redemption rights provided in Section 6.1 hereof shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to be held by the Sponsor or its Permitted Transferees and (b) if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), the redemption rights provided in Section 6.2 hereof shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to be held by the Sponsor or its Permitted Transferees. However, once such Private Placement Warrants are transferred (other than to Permitted Transferees in accordance with Section 2.6 hereof), the Company may redeem the Private Placement Warrants pursuant to Section 6.1 or 6.2 hereof, provided that the criteria for redemption are met, including the opportunity of the holder of such Private Placement Warrants to exercise the Private Placement Warrants prior to redemption pursuant to Section 6.4 hereof. Private Placement Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants and shall become Public Warrants under this Agreement, including for purposes of Section 9.8 hereof.

7.Other Provisions Relating to Rights of Holders of Warrants.

7.1.No Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or

to receive notice as shareholders in respect of the meetings of shareholders or the election of directors of the Company or any other matter.

7.2.Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may issue replacement Warrants in a form mutually agreed to by the Warrant Agent and the Company for those certificates alleged to have been lost, stolen, mutilated, or destroyed, absent notice to the Warrant Agent that such certificates have been acquired by a bona fide purchaser, and upon receipt by the Warrant Agent of an open penalty surety bond satisfactory to it and holding it and Company harmless, and in the case of a mutilated Warrant the surrender thereof. The Warrant Agent may, at its option, issue replacement Warrants for mutilated certificates upon presentation thereof without such indemnity. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

7.3.Reservation of Common Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Common Shares that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

7.4.Registration of Common Shares; Cashless Exercise at Company’s Option.

7.4.1.Registration of the Common Shares. The Company shall use its commercially reasonable efforts to maintain the effectiveness of the Registration Statement (and any replacement registration statement filed in respect thereof), and the current prospectus relating thereto, until the expiration or redemption of the Warrants in accordance with the provisions of this Agreement. During any period when the Company shall fail to have maintained an effective registration statement covering the issuance of the Common Shares issuable upon exercise of the Warrants, holders of the Warrants shall have the right to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act or another exemption) for that number of Common Shares equal to the lesser of (A) the quotient obtained by dividing (x) the product of the number of Common Shares underlying the Warrants, multiplied by the excess of the “Fair Market Value” (as defined below) less the Warrant Price by (y) the Fair Market Value and (B) 0.361. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume-weighted average price of the Common Shares as reported during the ten (10) trading day period ending on the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice of “cashless exercise” is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a “cashless basis” in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the Common Shares issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act) of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of doubt, unless and until all of the Warrants have been exercised or have expired, the Company shall continue to be

obligated to comply with its registration obligations under the first two sentences of this subsection 7.4.1.

7.4.2.Cashless Exercise at Company’s Option. If the Common Shares are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, (i) require holders of Public Warrants who exercise Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Common Shares issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its commercially reasonable efforts to register or qualify for sale the Common Shares issuable upon exercise of the Public Warrant under applicable blue sky laws to the extent an exemption is not available.

8.Concerning the Warrant Agent and Other Matters.

8.1.Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of Common Shares upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

8.2.Resignation, Consolidation, or Merger of Warrant Agent.

8.2.1.Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation or other entity organized and existing under the laws of the State of New York, in good standing and having its principal office in the United States of America, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing

for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

8.2.2.Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the Common Shares not later than the effective date of any such appointment.

8.2.3.Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be consolidated or any entity resulting from any merger or consolidation to which the Warrant Agent shall be a party or the acquiror of all or substantially all of the assets of the Warrant Agent shall be the successor Warrant Agent under this Agreement without any further act.

8.3.Fees and Expenses of Warrant Agent.

8.3.1.Remuneration. The Company agrees to pay the Warrant Agent reasonable compensation for its services as such Warrant Agent hereunder in accordance with a fee schedule to be mutually agreed upon and, pursuant to its obligations under this Agreement the Company agrees to reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder, including the reasonable compensation and expenses of the Warrant Agent’s agents and counsel as agreed.

8.3.2.Further Assurances.

8.4.1.Reliance on Company Statement. From time to time, Company may provide the Warrant Agent with instructions concerning the services performed by the Warrant Agent hereunder. In addition, whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Clerk, Secretary, Treasurer or Chief Financial Officer, Chief Executive Officer or President of the Company and delivered to the Warrant Agent. The Warrant Agent may also consult with legal counsel for the Warrant Agent or the Company with respect to any matter arising in connection with the services to be performed by the Warrant Agent under this Agreement. The Warrant Agent and its agents and subcontractors shall not be liable and shall be indemnified by Company for any action taken or omitted by the Warrant Agent in reliance upon any Company instructions or upon the advice or opinion of such counsel. The Warrant Agent shall not be held to have notice of any change of authority of any person, until receipt of written notice thereof from Company.

8.4.2.Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct, fraud or bad faith (which willful misconduct or gross negligence must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction). The Company agrees to indemnify the Warrant Agent and save it

harmless against any and all liabilities, including judgments, out-of-pocket costs and reasonable outside counsel fees, incurred or suffered by the Warrant Agent or to which it may become subject, arising from or out of, directly or indirectly, any claims or liability resulting from its actions as Warrant Agent pursuant hereto, except as a result of the Warrant Agent’s gross negligence, willful misconduct, fraud or bad faith (which willful misconduct or gross negligence must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction).

8.4.3.Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof).

The Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Common Shares to be issued pursuant to this Agreement or any Warrant or as to whether any Common Shares shall, when issued, be valid and fully paid and nonassessable.

8.4.4.Limitation of Liability. Notwithstanding anything contained herein to the contrary, the Warrant Agent’s aggregate liability during any term of this Agreement with respect to, arising from, or arising in connection with this Agreement, or from all Services provided or omitted to be provided under this Agreement, whether in contract, or in tort, or otherwise, is limited to, and shall not exceed, the amounts paid hereunder by the Company to the Warrant Agent as fees and charges, but not including reimbursable expenses, during the twelve (12) months immediately preceding the event for which recovery from the Warrant Agent is being sought.

8.4.5.Consequential Damages. Neither party to this Agreement shall be liable to the other party for any consequential, indirect, special or incidental damages under any provisions of this Agreement or for any consequential, indirect, punitive, special or incidental damages arising out of any act or failure to act hereunder even if that party has been advised of or has foreseen the possibility of such damages.

8.4.6.Survival. The Company’s obligations pursuant to this Section 8.4 shall survive the termination of this Agreement or removal of the Warrant Agent.

8.5.Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the express terms and conditions herein set forth.

8.6.[Reserved].

Computershare shall not be obligated to pay such interest, dividends or earnings to the Company, any holder or any other party.

8.9.Force Majeure. Notwithstanding anything to the contrary contained herein, the Warrant Agent will not be liable for any delays or failures in performance resulting from acts beyond its reasonable control including, without limitation, acts of God, terrorist acts, shortage of supply, breakdowns or malfunctions, interruptions or malfunction of computer facilities, or loss of data due to power failures or mechanical difficulties with information storage or retrieval systems, labor difficulties, war, or civil unrest.

8.10.Confidentiality.

Exhibit A Form of Warrant Certificate

Exhibit B Legend — Private Placement Warrants

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.

Number

This Warrant Certificate certifies that [ ], or registered assigns, is the registered holder of [ ] warrant(s) (the “Warrants” and each, a “Warrant”) to purchase shares of common stock, $0.0001 par value (“Common Shares”), of Proterra Inc, a Delaware corporation (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and nonassessable Common Shares as set forth below, at the exercise price (the “Warrant Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Each whole Warrant is initially exercisable for one fully paid and non-assessable Common Share. Fractional shares shall not be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a Common Share, the Company shall, upon exercise, round down to the nearest whole number the number of Common Shares to be issued to the Warrant holder. The number of Common Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.

The initial Warrant Price per one Common Share for any Warrant is equal to $11.50 per share. The Warrant Price is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.

Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement.

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York.

The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive [ ] Common Shares and are issued or to be issued pursuant to the Amended and Restated Warrant Agreement dated as of June 14, 2021 (as amended, the “Warrant Agreement”), duly executed and delivered by the Company to Computershare Inc., a Delaware corporation, and its wholly-owned subsidiary, Computershare Trust Company, N.A., a federally chartered trust company (collectively, the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of Election to Purchase set forth hereon properly completed and executed, together with payment of the Warrant Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

The Warrant Agreement provides that upon the occurrence of certain events the number of Common Shares issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted.

Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of the Company.

In the event that the Warrant has been called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement and a holder thereof elects to exercise its Warrant pursuant to a Make-Whole Exercise, the number of Common Shares that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) or Section 6.2 of the Warrant Agreement, as applicable.

In the event that the Warrant is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of Common Shares that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) of the Warrant Agreement.
