This Note Purchase Agreement (this “Agreement”) is dated as of June 28, 2019, by and between NG Advantage LLC, a Delaware limited liability company (the “Company”), and Clean Energy Finance, LLC, a California limited liability company (“Clean Energy”). The Company and Clean Energy hereby agree as follows:

The Company shall, prior to the Closing (as defined below), authorize the sale and issuance of (a) a convertible promissory note in the form attached hereto as Schedule A in the principal amount of up to $15,187,946.77 (the “Note”), (b) the Company’s Common Units (as defined in the Operating Agreement (as defined below)) into which the Note may be converted in accordance with the terms thereof (such Common Units, the “Units”), (c) the warrants in the form attached hereto as Schedule B to be issued in accordance with the Note (the “Warrants”), and (d) the Units issuable upon exercise of the Warrants (the Units, the Warrants and the Note are collectively referred to as the “Securities”). Subject to the terms and conditions of this Agreement, Clean Energy agrees to purchase the Note and the Warrants in accordance with the terms of this Agreement and the Note, and the Company agrees to sell and issue the Note and the Warrants to Clean Energy at the Closing. Capitalized but otherwise undefined terms used herein shall have the meanings provided therefor in the Note.

The purchase, sale and issuance of the Note to Clean Energy (the “Closing”) shall take place on the date hereof at the offices of Clean Energy, located at 4675 MacArthur Court, Suite 800, Newport Beach, California 92660.

At the Closing, the Company shall issue and deliver the Note to Clean Energy and shall update the Company’s unit ledger and all other applicable books and records to reflect such issuance. At the Closing, the Company shall issue and sell to Clean Energy the Warrant to purchase up to the number of Common Units as set forth therein.

The Company hereby represents and warrants to Clean Energy, as of the date hereof and as of the Closing (except for the representations and warranties that speak as of a specific date, which shall be made as of such date), as follows:

The Company is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware. The Company has all requisite limited liability company power and authority, and holds all governmental licenses, to own and operate its properties and assets, to carry on its business as presently conducted and as proposed to be conducted, to execute and deliver this Agreement, to issue and sell the Securities and to perform its obligations pursuant to this Agreement and the Amended and Restated Limited Liability Company Operating Agreement of the Company dated July 14, 2017, as subsequently amended on February 28, 2018, October 1, 2018, February 15, 2019 and on or about the date hereof (such amendment dated on or about the date hereof, the “Operating Agreement Amendment,” and such agreement, as so amended to date, the “Operating Agreement”). The Company is presently qualified to do business as a foreign limited liability company in each jurisdiction where the failure to be so qualified could reasonably be expected to have, individually or in the aggregate, a material adverse effect on (a) the Company’s condition, assets, properties, operating results, business or prospects, financially or otherwise, as now conducted and as proposed to be conducted, or (b) the prospect of repayment of any portion of the Obligations (a “Material Adverse Effect”).

The Units, when issued and delivered and paid for in compliance with the provisions of this Agreement and the Note, will be validly issued, fully paid and nonassessable. The Securities will be free of any liens or encumbrances, other than any liens or encumbrances created by Clean Energy; provided, however, that the Securities are subject to restrictions on transfer under U.S. state and/or federal securities laws and as set forth herein, in the Operating Agreement and in the Amended and Restated Right of First Offer and Co-Sale Agreement, dated as of October 14, 2014, among the Company, Clean Energy and the additional individuals and entities listed on Exhibit A and Exhibit B thereto (the “Right of First Offer and Co-Sale Agreement”). Except as set forth in the Operating Agreement or the Right of First Offer and Co-Sale Agreement, the Securities are not subject to any preemptive rights or rights of first offer.

All limited liability company action on the part of the Company and its managers, officers and members necessary for the authorization, execution, delivery and performance of this Agreement by the Company, the authorization, sale, issuance and delivery of the Securities, and the performance of all of the Company’s obligations under this Agreement, has been taken or will be taken prior to the Closing. This Agreement, when executed and delivered by the Company, shall constitute the valid and binding obligation of the Company, enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally and (b) as limited by rules of law governing specific performance, injunctive relief or other equitable remedies and by general principles of equity.

No consent, approval, order or authorization of or registration, qualification, designation, declaration or filing with any court, governmental authority or third party on the part of the Company is required in connection with the valid execution and delivery of this Agreement by the Company, the offer, sale or issuance of the Securities, or the performance by the Company of its obligations under this Agreement, except (a) the filing of such notices as may be required under the Securities Act and (b) such filings as may be required under applicable state securities laws, each of which will be timely filed within the applicable periods therefor.

Subject to the accuracy of Clean Energy’s representations and warranties in SECTION 4, the offer, sale and issuance of the Securities in conformity with the terms of this Agreement constitute transactions exempt from the registration requirements of the Securities Act and will not result in a violation of the qualification or registration requirements of applicable state securities laws, and neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemption.

The Company is not in violation of its Certificate of Formation as in effect on the date hereof or any term of the Operating Agreement, or, in any material respect, of any term or provision of any mortgage, indebtedness, indenture, contract, agreement, instrument, judgment, order or decree to which it is party or by which it is bound. To the best of the Company’s knowledge, the Company is not in violation of any federal, state or local statute, rule, regulation, order or restriction of any domestic or foreign government or any instrumentality or agency thereof applicable to the Company, the conduct of its business or its properties. The execution and delivery of this Agreement by the Company, the performance by the Company of its obligations pursuant to, and consummation of the transactions contemplated by, this Agreement, and the sale and issuance of the Securities, will not (a) result in any violation of, or conflict with, or constitute, with or without the passage of time and giving of notice, a default under, or constitute an event that could entitle any counterparty or other third party to exercise any additional rights under or result in the acceleration of the maturity of any material indebtedness of the Company or the performance of any obligation of the Company under, the Company’s Certificate of Formation or its Operating Agreement or any such mortgage, indebtedness, indenture, contract, agreement, instrument, judgment order or decree, (b) result in the violation of, or conflict with, any federal or state statute, rule or regulation applicable to the Company or its properties, (c) constitute an event that results in the creation of any mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of the Company, or (d) constitute an event that results in the suspension, revocation, impairment, forfeiture or nonrenewal of any material franchise, permit, license, authorization or approval applicable to the Company, its business or operations or any of its assets or properties.

The Company’s financial statements which have been delivered to Clean Energy fairly and accurately reflect the Company’s financial condition in accordance with GAAP as of the latest date of such financial statements. All financial projections and forecasts delivered to Clean Energy represent the Company’s best estimates and assumptions as to future performance, which the Company believes to be fair and reasonable as of the time made in the light of current and reasonably foreseeable business conditions. As of the date of this Agreement, the Company does not have any material liabilities, fixed or contingent, that are not reflected in the financial statements referred to above as have been delivered to Clean Energy on or prior to the date hereof, in the notes thereto or otherwise disclosed in writing to Clean Energy on or prior to the date hereof, other than liabilities arising in the ordinary course of business since the date of such financial statements. There has not been any material deterioration in the consolidated financial condition of the Company since the date of the most recent financial statements submitted to Clean Energy.

The Company possesses all licenses, patents, trademarks, trade names, service marks, copyrights, and other intellectual property rights, free from burdensome restrictions necessary to enable it to conduct its business.

The Company has filed all federal and other material tax returns and reports required to be filed, has made timely remittance of all material amounts as required by any governmental agency or authority and has paid all federal and other material taxes, assessments, fees and other governmental charges levied or imposed upon it or its properties, income or assets otherwise due and payable, except those which are being or will be contested in good faith by appropriate proceedings and for which adequate reserves have been provided in accordance with GAAP. The Company has not received any notice of any proposed tax assessment that would, if made, have a Material Adverse Effect.

All policies of insurance in effect of any kind or nature owned by or issued to the Company, including policies of life, fire, theft, product liability, public liability, property damage, other casualty, employee fidelity, workers’ compensation, property and liability insurance, (a) are, together with all policies of employee health and welfare and title insurance, if any, in full force and effect, (b) comply in all respects with the applicable requirements set forth herein and (c) are of a nature and provide such coverage, including through self-insurance, retentions and deductibles, as is customarily carried by companies engaged in similar businesses and owning similar properties in the same general areas in which the Company operates.

As of the date hereof, (i) the Company is not engaged in any joint venture or partnership with any other Person, and (ii) the Company has no Subsidiaries.

On and as of the date hereof and the date of the Closing, no event has occurred or condition exists with respect to the Company or any other Person that has resulted in, or could reasonably be expected to result in, a Material Adverse Effect.

The Company has exercised reasonable care, in accordance with the rules and guidance of the Securities and Exchange Commission (“SEC”) to determine whether any Covered Person (as defined below) is subject to any of the “bad actor” disqualifications described in Rule 506(d)(1)(i) through (viii) under the Securities Act (“Disqualification Events”). To the Company’s knowledge, no Covered Person is subject to a Disqualification Event, except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3) under the Securities Act. The Company has complied, to the extent applicable, with any disclosure obligations under Rule 506(e) under the Securities Act. “Covered Persons” are those persons specified in Rule 506(d)(1) under the Securities Act, including the Company; any predecessor or affiliate of the Company; any director, executive officer, other officer participating in the offering of the Securities, general partner or managing member of the Company; any beneficial owner of 20% or more of the Company’s outstanding voting equity securities, calculated on the basis of voting power; any promoter (as defined in Rule 405 under the Securities Act) connected with the Company in any capacity at the time of the sale of the Securities; and any person that has been or will be paid (directly or indirectly) remuneration for solicitation of purchasers in connection with the sale of the Securities (a “Solicitor”), any general partner or managing member of any Solicitor, and any director, executive officer or other officer participating in the offering of any Solicitor or general partner or managing member of any such Solicitor.

Except as disclosed in writing to Clean Energy prior to the date of this Agreement, there are no actions, suits, investigations, or proceedings pending or, to the knowledge of the Company, threatened in writing by or against the Company involving more than One Hundred Thousand Dollars ($100,000.00).

The fair salable value of the Company’s assets (including goodwill minus disposition costs) exceeds the fair value of the Company’s liabilities; the Company is not left with unreasonably small capital after the transactions in this Agreement; and the Company is able to pay its debts (including trade debts) as they mature.

The Company has fully provided Clean Energy with all the information necessary for Clean Energy to decide whether to purchase the Securities. Neither this Agreement, nor any other statements or certificates made or delivered in connection herewith, contains any untrue statement of a material fact or, to the best of the Company’s knowledge, omits to state a material fact necessary to make the statements herein or therein not misleading, in light of the circumstances in which they were made. With respect to any projections of the Company’s future operations provided by the Company to Clean Energy, the Company represents that such projections were prepared in good faith and that the Company believes there is a reasonable basis for such projections.

Clean Energy hereby represents and warrants to the Company, as of the date hereof and as of the Closing (except for the representations and warranties that speak as of a specific date, which shall be made as of such date), as follows:

Clean Energy understands that the offer and sale of the Securities have not been, and will not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act, the availability of which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of Clean Energy’s representations as expressed herein or otherwise made pursuant hereto.

Clean Energy is acquiring the Units for investment for its own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof, and Clean Energy has no present intention of selling, granting any participation in, or otherwise distributing the same. Clean Energy further represents that it does not have any contract, undertaking, agreement or arrangement with any person or entity to sell, transfer or grant participation to such person or entity or to any third person or entity with respect to any of the Securities.

Clean Energy has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company and acknowledges that it can protect its own interests. Clean Energy has such knowledge and experience in financial and business matters to be capable of evaluating the merits and risks of its investment in the Company.

Clean Energy understands and acknowledges that the Company has a limited financial and operating history and that an investment in the Company is highly speculative and involves substantial risks. Clean Energy can bear the economic risk of its investment and is able, without impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment hereunder.

Clean Energy acknowledges that the Securities must be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available. Clean Energy is aware of the provisions of Rule 144 promulgated under the Securities Act which permit resale of securities purchased in a private placement subject to the satisfaction of certain conditions, which may include, among other things, the availability of certain current public information about the Company; the resale occurring not less than a specified period after a party has purchased and paid for the security to be sold; the number of securities being sold during any three-month period not exceeding specified limitations; the sale being effected through a “brokers’ transaction,” a transaction directly with a “market maker” or a “riskless principal transaction” (as those terms are defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder); and the filing of a Form 144 notice, if applicable. Clean Energy understands that the current public information about the Company referred to above is not now available, and the Company has no present plans to make such information available. Clean Energy acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 at the time Clean Energy wishes to sell the Securities, and that, in such event, Clean Energy may be precluded from selling such securities under Rule 144, even if the other applicable requirements of Rule 144 have been satisfied. Clean Energy acknowledges that, in the event the applicable requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Securities. Clean Energy understands that, although Rule 144 is not exclusive, the SEC has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such persons and the brokers who participate in the transactions do so at their own risk.

Clean Energy understands and acknowledges that no public market now exists for the Securities or any other securities issued by the Company, and that the Company has made no assurances that a public market will ever exist for such securities.

(a)    Clean Energy has all requisite power and authority to execute and deliver this Agreement and to perform its obligations pursuant to this Agreement. All limited liability company or other applicable action on the part of Clean Energy necessary for the authorization, execution, delivery and performance of this Agreement by Clean Energy, and the performance of all of Clean Energy’s obligations under this Agreement, has been taken or will be taken prior to the Closing.

(b)    This Agreement, when executed and delivered by Clean Energy, will constitute the valid and legally binding obligation of such Investor, enforceable in accordance with its terms, except: (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, and

(ii)as limited by rules of law governing specific performance, injunctive relief or other equitable remedies or by general principles of equity.

Clean Energy understands and agrees that the certificates evidencing the Securities, or any other securities issued in respect of the Securities upon any unit split, unit dividend, recapitalization, merger, consolidation or similar event, shall bear the following legend (in addition to any legend required by this Agreement, the Right of First Offer and Co-Sale Agreement or under applicable state securities laws):

“THE OFFER AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE AND ANY SECURITIES INTO WHICH THEY MAY BE CONVERTIBLE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE, AND SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT AND/OR APPLICABLE STATE SECURITIES LAWS, UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED, OR UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT.”

Clean Energy’s obligation to consummate the transactions contemplated by this Agreement is subject to the fulfillment on or before the Closing of each of the following conditions, in each case unless waived by Clean Energy:

Clean Energy shall have received, in form and substance satisfactory to Clean Energy, such documents, and completion of such other matters, as Clean Energy may reasonably deem necessary or appropriate, including, without limitation:

All limited liability company and other proceedings in connection with the transactions contemplated at the Closing and all documents incident thereto shall be satisfactory in form and substance to Clean Energy and its counsel, and Clean Energy or its counsel shall have received all such counterpart original and certified or other copies of such other documents as any of them may request.

At or prior to the Closing, the Company, its managers and all then-current members of the Company shall have taken all action to fully waive any rights of first offer, preemptive rights or any other rights in connection with the sale and issuance of the Securities hereunder.

Clean Energy shall have performed or complied with all covenants, agreements and conditions contained in this Agreement to be performed or complied with by it on or prior to the date of the Closing.

Except as expressly provided herein, neither this Agreement nor any term hereof may be amended or waived other than by a written instrument signed by the Company and Clean Energy. Any such amendment or waiver effected in accordance with this Section 7.1 shall be binding upon each holder of any securities purchased under this Agreement at the time outstanding (including securities into which such securities have been converted or exchanged or for which such securities have been exercised) and each future holder of all such securities.

All remedies, either under this Agreement or by applicable law or otherwise afforded to any party to this Agreement, shall be cumulative and not alternative and a party’s exercise of any such remedy will not constitute a waiver of such party’s right to assert any other legal remedy available to it.

If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Agreement, and such court will replace such illegal, void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the greatest extent possible, the same economic, business and other purposes of the illegal, void or unenforceable provision.

During such time as this Note is outstanding, if the Company shall, at any time after the Original Issuance Date, declare or make any distribution of its assets (or rights to acquire its assets) to holders of its Common Units, by way of return of capital or otherwise (including any distribution of cash, units, stock or other securities, property or options by way of a spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction, but excluding any Tax Distribution (as defined in the Operating Agreement)) (a “Distribution”), then, in each such case, upon the conversion of this Note, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of Common Units acquirable upon full conversion of the outstanding principal amount of this Note (without regard to any limitations on exercise hereof) immediately before the date of such Distribution.

(iii)    Reclassification. If any reclassification of the equity of the Company shall be effected at any time while this Note is outstanding in such a way that holders of Common

Units shall be entitled to receive units, stock, securities or other assets or property, then, as a condition of such reclassification, lawful and adequate provisions shall be made so that the Holder hereof shall thereafter have the right to receive upon a conversion of this Note (in lieu of the Common Units immediately theretofore receivable upon the conversion of this Note) such units, stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of then outstanding Common Units equal to the number of Common Units immediately theretofore receivable upon conversion of this Note. In any such reclassification, appropriate provision shall be made with respect to the rights and interests of the Holder of this Note so that the provisions hereof (including, without limitation, provisions for adjustments of the Conversion Price and of the number of Common Units receivable upon conversion of this Note) shall thereafter be applicable, as nearly as possible, in relation to any units, stock, securities or other assets or property thereafter deliverable upon the conversion hereof.

(i)    Mechanics. If this Note is to be converted, the Holder shall deliver a written conversion notice to the Company, which shall notify the Company of its election to convert pursuant to Section 4(a) or Section 4(b) and specify the principal amount of the Note and accrued and unpaid interest under the Note to be converted. Any such conversion shall be effective as of the close of business on the date on which such written conversion notice is delivered to the Company in accordance with the terms of this Note, and as soon as practicable thereafter, the Company shall (A) update its unit ledger and all other applicable books and records to reflect the issuance to the Holder of the number of Common Units issuable upon such conversion and (B) deliver to the Holder a check payable to the Holder for any cash amounts owed as described in Section 4(d)(ii). If any such conversion is for all outstanding amounts owed under this Note, then, concurrently with or as soon as practicable after delivery of such a written conversion notice, the Holder shall deliver to the Company the original of this Note (or a notice to the effect that the original Note has been lost, stolen or destroyed) for cancellation.

(ii)    No Fractional Common Units. No fractional Common Units shall be issued upon conversion of this Note. In lieu of the Company issuing any fractional Common Units to the Holder upon a conversion of this Note, the Company shall pay to the Holder an amount equal to the product obtained by multiplying the applicable Conversion Price by the fraction of a Common Unit not so issued.

(iii)    Effect of Conversion. At such time as the conversion of all or any portion of this Note has been effected as set forth in Section 4(d)(i), the rights of the Holder under this Note, to the extent of the conversion, shall cease, and the Holder shall thereafter be deemed to have become the holder of record of the Common Units issuable upon such conversion (whether or not this Note has been delivered to the Company for cancellation in the event such conversion is for all outstanding amounts owed under this Note). Upon conversion of this Note in full and the payment of any cash amounts owed pursuant to Section 4(d)(ii), the Company shall be forever released from all its obligations and liabilities under this Note and this Note shall be deemed of no further force or effect, whether or not the original of this Note has been delivered to the Company for cancellation as set forth in Section 4(d)(i).

(iv)    Compliance with Laws and Regulations. The Company shall take all such actions as may be necessary to ensure that all Common Units issued upon conversion of all or any portion of this Note may be so issued without violation of any applicable law or governmental regulation or any requirement of any domestic securities exchange upon which such Common Units may be then listed (except for official notice of issuance which shall be immediately delivered by the Company upon such issuance).

This Warrant to Purchase Common Units (this “Warrant”) certifies that Clean Energy, a California corporation (“Clean Energy,” and Clean Energy or such other Person as is the registered holder of this Warrant, the “Holder”), or its registered assigns, for value received, is entitled to purchase, at the Unit Purchase Price (as defined below), from NG Advantage LLC, a Delaware limited liability company (the “Company”), up to the number of fully paid and nonassessable Common Units as set forth below:

For purposes of this Warrant, “Common Units” shall mean the Company’s Common Units or any class or type of security into which the Company’s Common Units may be converted or for which the Company’s Common Units may be exchanged in connection with any recapitalization, conversion to the corporate form, or any other similar transaction, and “Warrant Units” shall mean the Common Units purchasable hereunder.

The following sets forth the rights of the Holder and the conditions to which this Warrant is subject, and to which the Holder, by the acceptance of this Warrant, and the Company agree:

1.Exercise Period; Unit Purchase Price. This Warrant shall be exercisable, at the option of the Holder, at any time and from time to time and for all or any part of the Warrant Units (but not for a fraction of a unit) which may be purchased hereunder, from and after the Original Issuance Date, as defined below (such date, the “Initial Exercise Date”) up to and including 5:00 p.m. (Pacific Time) on the ten (10)-year anniversary of the Original Issuance Date, as defined below (the “Expiration Date”), upon (a) surrender to the Company at its principal office (or at such other location as the Company may advise the Holder in writing) of this Warrant properly endorsed (or a notice to the effect that the original Warrant has been lost, stolen or destroyed), (b) delivery to the Company of the Form of Subscription attached hereto duly completed and executed, and (c) payment to the Company pursuant to Section 3 of the aggregate Unit Purchase Price for the number of Warrant Units for which this Warrant is being exercised, determined in accordance with the provisions hereof. For purposes of this Warrant, “Unit Purchase Price” shall mean the lesser

of $10.00 or 90% of the per Unit Purchase Price in the Equity Offering (as defined in the Engagement Letter dated May 1, 2019 between the Company and Raymond James & Associates, Inc.). The Unit Purchase Price and the number of Warrant Units purchasable hereunder are subject to adjustment as provided in Section 5 of this Warrant.

2.Exercise Mechanics. No fractional units shall be issued upon the exercise of this Warrant, and the Company shall in lieu thereof make payment to the Holder of cash, by wire transfer of immediately available lawful tender of the United States, in the amount of such fraction multiplied by the fair market value (as defined below) of one Warrant Unit on the date of exercise. Any Warrant Units purchased upon the exercise of this Warrant shall be and are deemed to be issued to the Holder as the record owner of such units as of the close of business on the date on which the exercise conditions set forth in Section 1(a), (b) and (c) have been satisfied. After any rights represented by this Warrant have been so exercised, the Company shall promptly (a) deliver to the Holder, at the Company’s expense, certificates for the Warrant Units so purchased (if such units are then certificated), together with any other securities or property to which the Holder hereof is entitled upon such exercise, and (b) reflect such issuance in its books and records. Each certificate so delivered shall be in such denominations of the Warrant Units as may be requested by the Holder and shall be registered in the name of such Holder. In the event of a purchase of less than all the Warrant Units, the Company shall promptly execute and deliver to the Holder an Acknowledgement in the form attached hereto indicating the number of Warrant Units which remain subject to this Warrant, if any. Notwithstanding anything to the contrary contained herein, unless the Holder otherwise notifies the Company, this Warrant shall be deemed to be automatically exercised using the Net Issuance method of payment pursuant to Section 3 immediately prior to the time on the Expiration Date at which this Warrant ceases to be exercisable.

3.Payment for Units. The aggregate Unit Purchase Price for Warrant Units being purchased hereunder may be paid either (a) in cash by wire transfer of immediately available lawful tender of the United States, (b) if the fair market value of one Warrant Unit on the date of exercise is greater than the then applicable Unit Purchase Price, by surrender of a number of Warrant Units which have a fair market value equal to the aggregate purchase price of the Warrant Units being purchased (“Net Issuance”) as determined herein, or (c) any combination of the foregoing. If the Holder elects the Net Issuance method of payment, the Company shall issue to the Holder upon exercise a number of Warrant Units determined in accordance with the following formula:

(i) if the date of exercise of this Warrant is after the commencement of trading of the Common Units on a securities exchange or over-the-counter quotation system but prior to the closing of the initial public offering of the Common Units pursuant to a registration statement filed and declared effective under the Securities Act (as defined below) (the “IPO”), the price per Common Unit to the public set forth on the final prospectus relating to the IPO, multiplied by the number of Common Units into which each Warrant Unit is then convertible, (ii) if the Common Units are then traded on a securities exchange, the average of the closing prices of such Common Units on such exchange over the thirty (30) calendar day period (or portion thereof) ending three (3) days prior to the date of exercise of this Warrant, multiplied by the number of Common Units into which each Warrant Unit is then convertible, (iii) if the Common Units are then regularly traded on an over-the-counter quotation system, the average of the closing sale prices or secondarily the closing bid prices of such Common Units over the thirty (30) calendar day period (or portion thereof) ending three (3) days prior to the date of exercise of this Warrant, multiplied by the number of Common Units into which each Warrant Unit is then convertible, or (iv) if there is no active public market for the Common Units, the fair market value of one Warrant Unit as determined in good faith by the Board of Managers or equivalent body of the Company (which determination shall include the approval of at least two (2) of the CLNE Managers (as defined in the Company’s Limited Liability Company Agreement)).

4.Units to be Fully Paid; Reservation of Units. All Common Units which may be issued upon the exercise of the rights represented by this Warrant shall, upon issuance, be duly authorized, validly issued, fully paid and nonassessable and free from all preemptive rights of any member or other equity holder of the Company and free of all taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company shall at all times have authorized and reserved, for the purpose of issue or transfer upon exercise of the rights represented by this Warrant, a sufficient number of authorized but unissued Common Units, or other securities and property, when and as required to provide for the exercise of the rights represented by this Warrant.

5.Adjustments. The Unit Purchase Price and the number of Warrant Units purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events as set forth in this Section 5. Upon each adjustment of the Unit Purchase Price as set forth in this Warrant, the Holder of this Warrant shall thereafter be entitled to purchase, at the Unit Purchase Price resulting from such adjustment, the number of Common Units obtained by multiplying the Unit Purchase Price in effect immediately prior to such adjustment by the number of Common Units purchasable pursuant hereto immediately prior to such adjustment, and dividing the product thereof by the Unit Purchase Price immediately after such adjustment.

(a)    Adjustment to Reference Securities.    If the Reference Securities are Convertible Securities, and if the price per Common Unit at which such Reference Securities may be exercised, converted or exchanged is adjusted from time to time after the date of issuance of the Reference Securities pursuant to the terms of the Reference Securities, then the Unit Purchase Price shall be equivalently adjusted; provided that the Unit Purchase Price shall not be reduced pursuant to this Section 5(a) to an amount that lower than the Unit Purchase Price on the date on which this Warrant is first issued, as set forth above (the “Original Issuance Date”).

(b)    Subdivisions; Combinations. If the Company at any time while this Warrant is outstanding subdivides (by any unit split, unit distribution, recapitalization or otherwise) its outstanding Common Units into a greater number of units, the Unit Purchase Price in effect

immediately prior to such subdivision shall be proportionately reduced. If the Company at any time combines (by reverse unit split or otherwise) its outstanding Common Units into a smaller number of units, the Conversion Price in effect immediately prior to such combination shall be proportionately increased.

(c)    Distributions. If the Company at any time while this Warrant is outstanding declares or makes any distribution of its assets (or rights to acquire its assets) to holders of its Common Units, by way of return of capital or otherwise (including any distribution of cash, units, stock or other securities, property or options by way of a spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction, but excluding any Tax Distribution (as defined in the Operating Agreement)) (a “Distribution”), then, in each such case, upon the exercise of this Warrant, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of Common Units acquirable upon full exercise of this Warrant (without regard to any limitations on exercise hereof) immediately before the date of such Distribution.

(d)    Reclassification. If any reclassification of the equity of the Company shall be effected at any time while this Warrant is outstanding in such a way that holders of Common Units shall be entitled to receive units, stock, securities or other assets or property, then, as a condition of such reclassification, lawful and adequate provisions shall be made so that the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the Warrant Units immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such units, stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of then outstanding Common Units equal to the number of Common Units immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby. In any such reclassification, appropriate provision shall be made with respect to the rights and interests of the Holder of this Warrant so that the provisions hereof (including, without limitation, provisions for adjustments of the Unit Purchase Price and of the number of Warrant Units purchasable and receivable upon the exercise of this Warrant) shall thereafter be applicable, as nearly as possible, in relation to any units, stock, securities or other assets or property thereafter deliverable upon the exercise hereof.

(e)    Acquisition. In the event of any reorganization, consolidation or merger of the Company, transfer of all or substantially all of the assets of the Company or any sale of more than a majority of the then outstanding securities of the Company other than a mere reincorporation transaction (an “Acquisition”), then, as a condition of such Acquisition, lawful and adequate provisions shall be made so that the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the Warrant Units immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby), at the same aggregate exercise price, such units, stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of outstanding Common Units equal to the number of Common Units immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby. In the event of any Acquisition, appropriate provision shall be made with respect to the rights and interests of the Holder of this Warrant so that the provisions hereof (including, without limitation, provisions for adjustments of the Unit Purchase Price and of the number of Warrant Units purchasable and receivable upon the exercise of this Warrant) shall thereafter be applicable, as nearly as may be, in relation to any units, stock, securities or other assets or property thereafter deliverable upon the exercise hereof.

(a)    Adjustments. Upon any adjustment of the Unit Purchase Price or any increase or decrease in the number of Warrant Units purchasable upon the exercise of this Warrant, the Company shall promptly give written notice thereof to the registered Holder of this Warrant. The notice shall be signed by an officer of the Company and shall state the Unit Purchase Price resulting from such adjustment and the increase or decrease, if any, to the number of Warrant Units purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

(b)    Other Notices. In the event of:

(i)    Any distribution to any holders of any class of securities of the Company (other than a Tax Distribution, as defined in the Operating Agreement) or any grant to any such holders of a right to subscribe for, purchase or otherwise acquire any units or any other securities or property, or to receive any other right;

(ii)    Any capital reorganization of the Company, any reclassification or recapitalization of the equity of the Company or any transfer of all or substantially all of the assets of the Company to any other Person or any consolidation or merger involving the Company;

(iii)    Any voluntary or involuntary dissolution, liquidation or winding- up of the Company; or

(iv)    An IPO,

the Company shall, at least ten (10) days prior to the earliest date specified herein, mail to the Holder a notice specifying (A) the date on which the distribution or right is to be made and the amount and character of such distribution or right; and (B) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding-up is expected to become effective and the date for determining the Company’s members entitled to vote thereon.

7.No Voting or Distribution Rights. Nothing contained in this Warrant shall be construed as conferring upon the Holder hereof the right to vote or to consent or to receive notice as a member of the Company or any other matters or any rights whatsoever as a member of the Company. No distributions shall be payable or accrued in respect of this Warrant or the interest represented hereby or the Warrant Units purchasable hereunder until, and only to the extent that, this Warrant shall have been exercised.

8.Investment Representations. By accepting this Warrant from the Company, the Holder represents and warrants to the Company that it (a) is an “accredited investor” as such term is defined in Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”), (b) is acquiring this Warrant with the present intention of holding this Warrant for purposes of investment and not with a view to the public resale or distribution within the meaning of the Securities Act, and (c) understands that this Warrant and the securities issuable upon exercise hereof have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein.

(i)    Subject to the restrictions on transfer described in this Section 9(a), the rights and obligations of the Company and the Holder shall be binding upon and benefit the successors, assigns, heirs, administrators and transferees of the parties.

(ii)    The Holder shall be entitled to transfer, assign or otherwise dispose of this Warrant and the securities into which this Warrant may be exercised at any time and from time to time; provided that the Holder shall give prior written notice to the Company of any such transfer, assignment or other disposition. Each Warrant so transferred and each certificate representing other securities so transferred shall bear a legend in substantially the form set forth on the first page of this Warrant as to the applicable restrictions on transferability to ensure compliance with the Securities Act, unless in the opinion of counsel for the Company such legend is not required to ensure compliance with the Securities Act. Subject to the foregoing, transfers, assignments or other dispositions of this Warrant shall be registered upon registration books maintained for such purpose by or on behalf of the Company. Prior to presentation of this Warrant (or a notice to the effect that the original Warrant has been lost, stolen or destroyed) for registration of transfer, the Company shall treat the registered holder hereof as the owner and holder of this Warrant and all rights represented hereby.

(iii)    Neither this Warrant nor any of the rights, interests or obligations hereunder may be assigned, by operation of law or otherwise, in whole or in part, by the Company without the prior written consent of the Holder.

(b)    Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, sent by electronic mail or otherwise delivered by hand, messenger or courier service addressed:

(i) if to the Holder, to the attention of the SVP Corp Trans & CLO of Clean Energy at 4675 MacArthur Court, Suite 800, Newport Beach, California 92660, or at ***@*** (email address), or at such other address as such Holder shall have furnished the Company in writing in accordance with this Section 9(b); and (ii) if to the Company, to the attention of the Chief Executive Officer of the Company at 480 Hercules Drive, Colchester, Vermont 05446, or at ***@*** (email address), or at such other address as the Company shall have furnished the Holder in writing in accordance with this Section 9(b). Each such notice or other communication shall for all purposes of this Agreement be treated as effective or having been given (A) if delivered by hand, messenger or courier service, when delivered (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying next-business-day delivery, one business day after deposit with the courier), or (B) if sent via mail, at the earlier of its receipt or five days after the same has been deposited in a regularly-maintained receptacle for the deposit of the United States mail, addressed and mailed as aforesaid, or (C) if sent via electronic mail, when directed to the relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day.

(c)    Amendment. Except as expressly provided herein, neither this Warrant nor any term hereof may be amended or waived other than by a written instrument signed by the Company and the Holder. Any such amendment or waiver effected in accordance with this Section

9(c) shall be binding upon each Holder of this Warrant or any securities issuable upon conversion hereof, including any future holder of such securities.

(d)    Severability. If any provision of this Warrant becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Warrant, and such court will replace such illegal, void or unenforceable provision of this Warrant with a valid and enforceable provision that will achieve, to the greatest extent possible, the same economic, business and other purposes of the illegal, void or unenforceable provision. The balance of this Warrant shall be enforceable in accordance with its terms.

(e)    Governing Law. This Warrant shall be governed in all respects by the internal laws of the State of Delaware as applied to agreements entered into among Delaware residents to be performed entirely within Delaware, without regard to principles of conflicts of law.

(f)    Waiver of Jury Trial. EACH OF THE COMPANY AND, BY ITS ACCEPTANCE OF THIS WARRANT, THE HOLDER IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING (WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATED TO THIS WARRANT.
