The “Series A Preferred Original Issue Price” shall mean $5.3246735 per share, subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series A Preferred Stock.

(ii) From and after the date of the issuance of any shares of Series B Preferred Stock, the Company shall automatically increase the Series B Preferred Original Issue Price (as defined below) of each outstanding share of Series B Preferred Stock, on a quarterly basis, by an amount equal to 14% per annum (the “Series B PIK Accretion”).

(A) Each holder of shares of Series B Preferred Stock then outstanding shall be entitled to payment out of the assets of the Corporation available for distribution to its stockholders, prior and in preference to the holders of Series A Preferred Stock, Common Stock and any other class or series of capital stock of the Corporation ranking junior to the Series B Preferred Stock by reason of their ownership thereof in respect of payment on liquidation, dissolution or winding up or any Deemed Liquidation Event, in an amount per share of Series B Preferred Stock (such amount, the “Series B Liquidation Preference”) equal to the greater of (1) the Series B Preferred Original Issue Price, or (2) such amount per share as would have been payable had all shares of Series B Preferred Stock been converted into Series A Common Stock pursuant to Section IV.3(d) immediately prior to such liquidation, dissolution, winding up or Deemed

A-4

Liquidation Event (the amount payable pursuant to this sentence is hereinafter referred to as the “Series B Preferred Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series B Preferred Stock the full amount to which they shall be entitled under this Section IV.3(b)(i)(A) Section IV.3(b)(i), the holders of shares of Series B Preferred Stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(B) After the payment of all preferential amounts required to be paid to the holders of Series B Preferred Stock, each holder of shares of Series A Preferred Stock then outstanding shall be entitled to payment out of the assets of the Corporation available for distribution to its stockholders, prior and in preference to the holders of Common Stock and any other class or series of capital stock of the Corporation ranking junior to the Series A Preferred Stock by reason of their ownership thereof in respect of payment on liquidation, dissolution or winding up or any Deemed Liquidation Event, in an amount per share of Series A Preferred Stock (such amount, the “Series A Liquidation Preference”) equal to the greater of (1) the sum of (x) the Series A Preferred Original Issue Price, plus (y) any Accruing Series A Preferred Dividends accrued but unpaid to the date fixed for liquidation, dissolution or winding up or of the Deemed Liquidation Event (it being understood that the Series A Liquidation Preference as of any date shall for all purposes hereunder be deemed to include Accruing Series A Preferred Dividends that have accrued thereon, whether or not declared, since the dividend payment date immediately preceding the date of such liquidation, dissolution or winding up or Deemed Liquidation Event to the extent unpaid as of such date) or (2) such amount per share as would have been payable had all shares of Series A Preferred Stock been converted into Series A Common Stock pursuant to Section IV.3(d) immediately prior to such liquidation, dissolution, winding up or Deemed Liquidation Event (the amount payable pursuant to this sentence is hereinafter referred to as the “Series A Preferred Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series A Preferred Stock the full amount to which they shall be entitled under this Section IV.3(b)(i)(B), the holders of shares of Series A Preferred Stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

A-5

(ii) Payments to Holders of Common Stock. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation or Deemed Liquidation Event, after the payment of all preferential amounts required to be paid to the holders of shares of Convertible Preferred Stock, the remaining assets of the Corporation available for distribution to its stockholders shall be distributed among the holders of shares of Common Stock, pro rata based on the number of shares held by each such holder.

(iii) Deemed Liquidation Events.

(A) Each of the following events shall be considered a “Deemed Liquidation Event” unless the holders of at least 75% of the outstanding shares of Series A Preferred Stock and Series B Preferred Stock (with the shares of Series A Preferred Stock and Series B Preferred Stock voting on an “as converted basis” as if such shares had been converted into Series A Common Stock pursuant to Section IV.3(d) (whether or not such shares of Series B Preferred Stock are then convertible)) elect otherwise by written notice sent to the Corporation at least three (3) days prior to the effective date of any such event:

(1) a merger or consolidation in which

(I) the Corporation is a constituent party or

(II) a subsidiary of the Corporation is a constituent party and the Corporation issues shares of its capital stock pursuant to such merger or consolidation, except any such merger or consolidation involving the Corporation or a subsidiary in which the shares of capital stock of the Corporation outstanding immediately prior to such merger or consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such merger or consolidation, at least a majority, by voting power, of the capital stock of (1) the surviving or resulting corporation; or (2) if the surviving or resulting corporation is a wholly owned subsidiary of another corporation immediately following such merger or consolidation, the parent corporation of such surviving or resulting corporation; or

(2) the sale, lease, transfer, exclusive license or other disposition, in a single transaction or series of related transactions, by the Corporation or any subsidiary of the Corporation of all or substantially all the assets of the Corporation and its subsidiaries taken as a whole, or the sale or disposition (whether by merger, consolidation or otherwise) of one or more subsidiaries of the Corporation if substantially all of the assets of the Corporation and

A-6

its subsidiaries taken as a whole are held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of the Corporation;

provided, however, that a transaction or series of related transactions shall not constitute a Deemed Liquidation Event if its sole purpose is to change the state of the Corporation’s incorporation or to create a holding company that will be owned in substantially the same proportions by the stockholders who held the Corporation’s securities immediately prior to such transaction or series of related transactions.

(B) The Corporation shall not have the power to effect a Deemed Liquidation Event referred to in Section IV.3(b)(iii)(A)(1)(1) unless the agreement or plan of merger or consolidation for such transaction (the “Merger Agreement”) provides that the consideration payable to the stockholders of the Corporation shall be allocated among the holders of capital stock of the Corporation in accordance with Section IV.3(b)(i) and Section IV.3(b)(ii).

(C) In the event of a Deemed Liquidation Event referred to in Section IV.3(b)(iii)(A)(1)(II) or Section IV.3(b)(iii)(A)(2), if the Corporation does not effect a dissolution of the Corporation under the DGCL within ninety (90) days after such Deemed Liquidation Event, then (i) the Corporation shall send a written notice to each holder of Convertible Preferred Stock no later than the ninetieth (90th) day after the Deemed Liquidation Event advising such holders of their right (and the requirements to be met to secure such right) pursuant to the terms of the following clause (ii) to require the redemption of such shares of Convertible Preferred Stock; and (ii) if the holders of at least 75% of the then outstanding shares of Series A Preferred Stock and Series B Preferred Stock (with the shares of Series A Preferred Stock and Series B Preferred Stock voting on an “as converted basis” as if such shares had been converted into Series A Common Stock pursuant to Section IV.3(d) (whether or not such shares of Series B Preferred Stock are then convertible)) so request in a written instrument delivered to the Corporation not later than one hundred twenty (120) days after such Deemed Liquidation Event, the Corporation shall use the consideration received by the Corporation for such Deemed Liquidation Event (net of any retained liabilities associated with the assets sold or technology licensed, as determined in good faith by the Board of Directors), together with any other assets of the Corporation available for distribution to its stockholders, all to the extent permitted by Delaware law governing distributions to stockholders (the “Available Proceeds”), on the one hundred fiftieth (150th) day after such Deemed Liquidation Event, to redeem all outstanding shares of Convertible Preferred Stock at a price per share equal

A-7

to Series A Preferred Liquidation Amount or the Series B Preferred Liquidation Amount, as applicable. Notwithstanding the foregoing, in the event of a redemption pursuant to the preceding sentence, if the Available Proceeds are not sufficient to redeem all outstanding shares of Convertible Preferred Stock, the Corporation shall ratably redeem each holder’s shares of Convertible Preferred Stock to the fullest extent of such Available Proceeds in conformity with the priorities set forth in Section IV.3(b)(i) and Section IV.3(b)(ii), and shall redeem the remaining shares as soon as it may lawfully do so under the DGCL governing distributions to stockholders. Prior to the distribution or redemption provided for in this Section IV.3(b)(iii)(C), the Corporation shall not expend or dissipate the consideration received for such Deemed Liquidation Event, except to discharge expenses incurred in connection with such Deemed Liquidation Event or in the ordinary course of business.

(D) If the amount deemed paid or distributed under this Section IV.3(b)(iii) is made in property other than in cash, the value of such distribution shall be the fair market value of such property, determined as follows:

(1) For securities not subject to investment letters or other similar restrictions on free marketability,

(I) if traded on a securities exchange, the value shall be deemed to be the average of the closing prices of the securities on such exchange or market over the thirty (30) day period ending three (3) days prior to the closing of such transaction;

(II) if actively traded over-the-counter, the value shall be deemed to be the average of the closing bid prices over the thirty (30) day period ending three (3) days prior to the closing of such transaction; or

(III) if there is no active public market, the value shall be the fair market value thereof, as determined in good faith by the Board of Directors of the Corporation.

(2) The method of valuation of securities subject to investment letters or other similar restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder’s status as an affiliate or former affiliate) shall take into account an appropriate discount (as determined in good faith by the Board of Directors) from the market value as determined pursuant to clause (1) above so as to reflect the approximate fair market value thereof.

A-8

(3) If holders of at least 75% of the then outstanding shares of Series A Preferred Stock and Series B Preferred Stock (with the shares of Series A Preferred Stock and Series B Preferred Stock voting on an “as converted basis” as if such shares had been converted into Series A Common Stock pursuant to Section IV.3(d) (whether or not such shares of Series B Preferred Stock are then convertible)) object to the valuation determined by the Board of Directors, then the value shall be the fair market value as mutually determined by the Corporation and such holders of Convertible Preferred Stock, and if the Corporation and such holders are unable to reach agreement, then the fair market value shall be established by an independent nationally recognized investment bank reasonably acceptable to both the Corporation and such holders of Convertible Preferred Stock.

(E) In the event of a Deemed Liquidation Event pursuant to Section IV.3(b)(iii)(A)(1)(I), if any portion of the consideration payable to the stockholders of the Corporation is payable only upon satisfaction of contingencies (the “Additional Consideration”), the Merger Agreement shall provide that (a) the portion of such consideration that is not Additional Consideration (such portion, the “Initial Consideration”) shall be allocated among the holders of capital stock of the Corporation in accordance with Section IV.3(b)(i) and Section IV.3(b)(ii) as if the Initial Consideration were the only consideration payable in connection with such Deemed Liquidation Event; and (b) any Additional Consideration which becomes payable to the stockholders of the Corporation upon satisfaction of such contingencies shall be allocated among the holders of capital stock of the Corporation in accordance with Section IV.3(b)(i) and Section IV.3(b)(ii) after taking into account the previous payment of the Initial Consideration as part of the same transaction. For the purposes of this Section IV.3(b)(iii)(E), consideration placed into escrow or retained as holdback to be available for satisfaction of indemnification or similar obligations in connection with such Deemed Liquidation Event shall be deemed to be Additional Consideration.

(c) Voting. On any matter presented to the stockholders of the Corporation for their action or consideration at any meeting of stockholders of the Corporation (or by written consent of stockholders in lieu of meeting):

(i) Each holder of outstanding shares of Series A Preferred Stock shall be entitled to cast the number of votes equal to the number of whole shares of Series A Common Stock into which the shares of Series A Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter. Except as provided by law or by the other provisions of the Certificate of Incorporation, holders of Series A Preferred Stock shall vote together with the holders of those shares of Series B Preferred Stock and Common Stock entitled to vote on a particular matter, as a single class.

A-9

(ii) Notwithstanding anything to the contrary, until the expiration or early termination of the waiting period pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 with respect to the acquisition of Series B Preferred Stock by Energy Capital Partners III-C, LP (“ECP III-C”) as contemplated by the Subscription Agreements (the “Series B Subscription Agreements”), dated as of November 9, 2017, by and between the Corporation, one the one hand, and ECP III-C and the other holders of the Series B Preferred Stock, on the other hand (the “HSR Act Approval”), each holder of outstanding shares of Series B Preferred Stock shall not be entitled to any voting rights. Upon obtaining HSR Act Approval, each holder of outstanding shares of Series B Preferred Stock shall be entitled to cast the number of votes equal to the number of whole shares of Series A Common Stock into which the shares of Series B Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter (with the shares of Series B Preferred Stock voting on an “as converted basis” as if such shares had been converted into Series A Common Stock pursuant to Section IV.3(d) (whether or not such shares of Series B Preferred Stock are then convertible)). Except as provided by law or by the other provisions of the Certificate of Incorporation, holders of Series B Preferred Stock shall vote together with the holders of those shares of Series A Preferred Stock and Common Stock entitled to vote on a particular matter, as a single class.

(d) Optional Conversion. The holders of the Convertible Preferred Stock shall have conversion rights as follows (the “Conversion Rights”):

(i) Right to Convert.

(A) Conversion Ratio.

(1) Each share of Series A Preferred Stock shall be convertible, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into such number of fully paid and non-assessable shares of Series A Common Stock as is determined by dividing the Series A Preferred Original Issue Price by the Series A Preferred Conversion Price (as defined below) in effect at the time of conversion. The “Series A Preferred Conversion Price” shall initially be equal to $5.3246735. Such initial Series A Preferred Conversion Price, and the rate at which shares of Series A Preferred Stock may be converted into shares of Series A Common Stock, shall be subject to adjustment as provided below.

(2) Upon obtaining HSR Act Approval, each share of Series B Preferred Stock shall be convertible, at the option of the holder thereof, at any time and from time to time, at or after the earlier of (i) November 9, 2018, and (ii) immediately prior to the consummation of a “Sale of the Company” (as defined in the Investors Agreement (as defined below)), and without the payment

A-10

of additional consideration by the holder thereof, into such number of fully paid and non-assessable shares of Series A Common Stock as is determined by dividing the Series B Preferred Original Issue Price by the Series B Preferred Conversion Price (as defined below) in effect at the time of conversion. The “Series B Preferred Conversion Price” shall initially be equal to $3.73. Such initial Series B Preferred Conversion Price, and the rate at which shares of Series B Preferred Stock may be converted into shares of Series A Common Stock, shall be subject to adjustment as provided below.

(B) Termination of Conversion Rights. In the event of a liquidation, dissolution or winding up of the Corporation or a Deemed Liquidation Event, the Conversion Rights shall terminate at the close of business on the last full day preceding the date fixed for the payment of any such amounts distributable on such event to the holders of the applicable series of Convertible Preferred Stock.

(ii) Fractional Shares. No fractional shares of Series A Common Stock shall be issued upon conversion of the Convertible Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the fair market value of a share of Series A Common Stock as determined in good faith by the Board of Directors. Whether or not fractional shares would be issuable upon such conversion shall be determined on the basis of the total number of shares of Convertible Preferred Stock that the holder is at the time converting into Series A Common Stock and the aggregate number of shares of Series A Common Stock issuable upon such conversion.

(iii) Mechanics of Conversion.

(A) Notice of Conversion. In order for a holder of Convertible Preferred Stock to voluntarily convert shares of Convertible Preferred Stock into shares of Series A Common Stock, such holder shall (i) provide written notice to the Corporation’s transfer agent at the office of the transfer agent for the Convertible Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent) that such holder elects to convert all or any number of such holder’s shares of Convertible Preferred Stock and, if applicable, any event on which such conversion is contingent and (ii) if such holder’s shares are certificated, surrender the certificate or certificates for such shares of Convertible Preferred Stock (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate), at the office of the transfer agent for the Convertible Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent). Such

A-11

notice shall state such holder’s name or the names of the nominees in which such holder wishes the shares of Series A Common Stock to be issued. If required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form reasonably satisfactory to the Corporation, duly executed by the registered holder or his, her or its attorney duly authorized in writing. The close of business on the date of receipt by the transfer agent (or by the Corporation if the Corporation serves as its own transfer agent) of such notice and, if applicable, certificates (or lost certificate affidavit and agreement) shall be the time of conversion (the “Conversion Time”), and the shares of Series A Common Stock issuable upon conversion of the specified shares shall be deemed to be outstanding of record as of such date. The Corporation shall, as soon as practicable after the Conversion Time (i) issue and deliver to such holder of Convertible Preferred Stock, or to his, her or its nominees, a notice of issuance of uncertificated shares and may, upon written request, issue and deliver a certificate for the number of full shares of Series A Common Stock issuable upon such conversion in accordance with the provisions hereof and, may, if applicable and upon written request, issue and deliver a certificate for the number (if any) of the shares of Convertible Preferred Stock represented by any surrendered certificate that were not converted into Series A Common Stock, (ii) pay in cash such amount as provided in Section IV.3(d)(ii) in lieu of any fraction of a share of Series A Common Stock otherwise issuable upon such conversion and (iii) pay all applicable declared but unpaid dividends on the shares of Convertible Preferred Stock converted.

(B) Reservation of Shares. The Corporation shall, at all times when the Convertible Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued capital stock, for the purpose of effecting the conversion of the Convertible Preferred Stock, such number of its duly authorized shares of Series A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Convertible Preferred Stock; and if at any time the number of authorized but unissued shares of Series A Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Convertible Preferred Stock, the Corporation shall take such corporate action as may be necessary to increase its authorized but unissued shares of Series A Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation. Before taking any action which would cause an adjustment reducing the Series A Preferred Conversion Price or the Series B Preferred Conversion Price, as applicable, below the then par value of the shares of Series A Common Stock issuable upon conversion of the Convertible Preferred Stock, the Corporation will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and non-assessable shares of Series A Common Stock at such adjusted Series A Preferred Conversion Price or Series B Preferred Conversion Price, respectively.

A-12

(C) Effect of Conversion. All shares of Convertible Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate at the Conversion Time, except only the right of the holders thereof to receive shares of Series A Common Stock in exchange therefor, to receive payment in lieu of any fraction of a share otherwise issuable upon such conversion as provided Section IV.3(d)(ii) and to receive payment of any dividends declared but unpaid thereon. Any shares of Convertible Preferred Stock so converted shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Convertible Preferred Stock accordingly.

(D) No Further Adjustment. Upon any such conversion, no adjustment to the Series A Preferred Conversion Price shall be made for any declared but unpaid dividends on the Series A Preferred Stock surrendered for conversion or the Series A Common Stock delivered upon conversion.

(E) Taxes. The Corporation shall pay any and all issue and other similar taxes that may be payable in respect of any issuance or delivery of shares of Series A Common Stock upon conversion of shares of Convertible Preferred Stock pursuant to this Section IV.3(d). The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Series A Common Stock in a name other than that in which the shares of Convertible Preferred Stock so converted were registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Corporation the amount of any such tax or has established, to the reasonable satisfaction of the Corporation, that such tax has been paid.

(iv) Adjustments to Conversion Price for Diluting Issues.

(A) Special Definitions. For purposes of this ARTICLE TV, the following definitions shall apply:

(1) “Options” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities.

A-14

(V) shares of Common Stock, Options or Convertible Securities issued or issuable pursuant to the acquisition of another entity by the Corporation by merger, purchase of substantially all of the assets or a business line, unit or division or other reorganization or pursuant to a joint venture agreement, provided that such issuances are approved by the Board of Directors; or

(B) No Adjustment of Conversion Price. No adjustment in the Series A Preferred Conversion Price or the Series B Preferred Conversion Price shall be made as the result of the issuance or deemed issuance of Additional Shares of Common Stock if the Corporation receives written notice from the holders of at least 75% of the then outstanding shares of Series A Preferred Stock and Series B Preferred Stock (with the shares of Series A Preferred Stock and Series B Preferred Stock voting on an “as converted basis” as if such shares had been converted into Series A Common Stock pursuant to Section IV.3(d) (whether or not such shares of Series B Preferred Stock are then convertible)) agreeing that no such adjustment shall be made as the result of the issuance or deemed issuance of such Additional Shares of Common Stock.

(1) If the Corporation at any time or from time to time after the Series B Convertible Preferred Original Issue Date shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Exempt Securities) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date.

A-15

(2) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) pursuant to the terms of Section IV.3(d)(iv)(D), are revised as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase or decrease in the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the Corporation upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Series A Preferred Conversion Price or the Series B Preferred Conversion Price, as applicable, as would have obtained had such revised terms been in effect upon the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no readjustment pursuant to this clause (2) shall have the effect of increasing the Series A Preferred Conversion Price or the Series B Preferred Conversion Price to an amount which exceeds the lower of (i) the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) in effect immediately prior to the original adjustment made as a result of the issuance of such Option or Convertible Security, or (ii) the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) that would have resulted from any issuances of Additional Shares of Common Stock (other than deemed issuances of Additional Shares of Common Stock as a result of the issuance of such Option or Convertible Security) between the original adjustment date and such readjustment date.

A-16

(3) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are themselves Exempt Securities), the issuance of which did not result in an adjustment to the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) pursuant to the terms of Section IV.3(d)(iv)(D) (either because the consideration per share (determined pursuant to Section IV.3(d)(iv)(E)) of the Additional Shares of Common Stock subject thereto was equal to or greater than the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) then in effect, or because such Option or Convertible Security was issued before the Series B Convertible Preferred Original Issue Date), are revised after the Series B Convertible Preferred Original Issue Date as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) any decrease in the consideration payable to the Corporation upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted, and the Additional Shares of Common Stock subject thereto (determined in the manner provided in Section IV.3(d)(iv)(C)(1) shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(4) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) pursuant to the terms of Section IV.3(d)(iv)(D), the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) shall be readjusted to such Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) as would have obtained had such Option or Convertible Security (or portion thereof) never been issued.

A-17

(5) If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Corporation upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment to the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) provided for in this Section IV.3(d)(iv)(C) shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (2) and (3) of this Section IV.3(d)(iv)(C)). If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Corporation upon such exercise, conversion and/or exchange, cannot be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) that would result under the terms of this Section IV.3(d)(iv)(C)) at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) that such issuance or amendment took place at the time such calculation can first be made.

(D) Adjustment of Conversion Price Upon Issuance of Additional Shares of Common Stock. In the event the Corporation shall at any time after the Series B Convertible Preferred Original Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Section IV.3(d)(iv)(C)), without consideration or for a consideration per share less than the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) in effect immediately prior to such issue, then the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) shall be reduced, concurrently with such issue, to a price (calculated to the nearest one-hundredth of a cent) determined in accordance with the following formula:

A-18

CP₂ = CP₁* (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(1) “CP₂” shall mean the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) in effect immediately after such issue of Additional Shares of Common Stock;

(2) “CP₁” shall mean the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) in effect immediately prior to such issue of Additional Shares of Common Stock;

(3) “A” shall mean the number of shares of Common Stock outstanding immediately prior to such issue of Additional Shares of Common Stock (treating for this purpose as outstanding all shares of Common Stock issuable upon exercise of Options outstanding immediately prior to such issue or upon conversion or exchange of Convertible Securities (including the Convertible Preferred Stock) outstanding (assuming exercise of any outstanding Options therefor) immediately prior to such issue);

(4) “B” shall mean the number of shares of Common Stock that would have been issued if such Additional Shares of Common Stock had been issued at a price per share equal to CP_I (determined by dividing the aggregate consideration received by the Corporation in respect of such issue by CPO; and

(5) “C” shall mean the number of such Additional Shares of Common Stock issued in such transaction.

(E) Determination of Consideration. For purposes of this Section IV.3(d)(iv), the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows:

(1) Cash and Property: Such consideration shall:

(I) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation, excluding amounts paid or payable for accrued interest;

A-19

(II) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and

(III) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (I) and (II) above, as determined in good faith by the Board of Directors.

(2) Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Section IV.3(d)(iv)(C), relating to Options and Convertible Securities, shall be determined by dividing:

(I) The total amount, if any, received or receivable by the Corporation as consideration for the issuance of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

(II) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities.

A-20

Section IV.3(d)(iv)(D), and such issuance dates occur within a period of no more than 90 days from the first such issuance to the final such issuance, then, upon the final such issuance, the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) shall be readjusted to give effect to all such issuances as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any such subsequent issuances within such period).

(v) Adjustment for Stock Splits and Combinations. If the Corporation shall at any time or from time to time after the Series B Convertible Preferred Original Issue Date effect a subdivision of the outstanding Common Stock, the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) in effect immediately before that subdivision shall be proportionately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase in the aggregate number of shares of Common Stock outstanding. If the Corporation shall at any time or from time to time after the Series B Convertible Preferred Original Issue Date combine the outstanding shares of Common Stock, the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) in effect immediately before the combination shall be proportionately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in the aggregate number of shares of Common Stock outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(vi) Adjustment for Certain Dividends and Distributions. In the event the Corporation at any time or from time to time after the Series B Convertible Preferred Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable on the Common Stock in additional shares of Common Stock, then and in each such event the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) then in effect by a fraction:

(A) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and

A-21

(B) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

Notwithstanding the foregoing (a) if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) shall be recomputed accordingly as of the close of business on such record date and thereafter the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) shall be adjusted pursuant to this subsection as of the time of actual payment of such dividends or distributions; and (b) no such adjustment shall be made if the holders of Convertible Preferred Stock simultaneously receive a dividend or other distribution of shares of Series A Common Stock in a number equal to the number of shares of Series A Common Stock as they would have received if all outstanding shares of Convertible Preferred Stock had been converted into Series A Common Stock on the date of such event.

(vii) Adjustments for Other Dividends and Distributions. In the event the Corporation at any time or from time to time after the Series B Convertible Preferred Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation (other than a distribution of shares of Common Stock in respect of outstanding shares of Common Stock) or in other property and the provisions of Section IV.3(a) do not apply to such dividend or distribution, then and in each such event the holders of Convertible Preferred Stock shall receive, simultaneously with the distribution to the holders of Common Stock a dividend or other distribution of such securities or other property in an amount equal to the amount of such securities or other property as they would have received if all outstanding shares of Convertible Preferred Stock had been converted into Series A Common Stock on the date of such event.

(viii) Adjustment for Merger or Reorganization, etc. If there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Corporation in which the Common Stock (but not the Convertible Preferred Stock) is converted into or exchanged for securities, cash or other property (other than a transaction covered by Section IV.3(d)(iv), (vi) or (vii)), then, following any such reorganization, recapitalization, reclassification, consolidation or merger, each share of Convertible Preferred Stock shall thereafter be convertible in lieu of the Series A Common Stock into which it was convertible prior to such event into the kind and amount of securities, cash or other property which a holder of the number of shares of Series A Common Stock of the Corporation issuable upon conversion of one share of Convertible Preferred Stock immediately prior to such reorganization, recapitalization, reclassification, consolidation or merger

A-22

would have been entitled to receive pursuant to such transaction; and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors) shall be made in the application of the provisions in this Section IV.3(d) with respect to the rights and interests thereafter of the holders of the Convertible Preferred Stock, to the end that the provisions set forth in this Section IV.3(d) (including provisions with respect to changes in and other adjustments of the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock)) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the Convertible Preferred Stock. For the avoidance of doubt, nothing in this Section IV.3(d)(viii) shall be construed as preventing the holders of Convertible Preferred Stock from seeking any appraisal rights to which they are otherwise entitled under the DGCL in connection with a merger triggering an adjustment hereunder, nor shall this Section IV.3(d)(viii) be deemed conclusive evidence of the fair value of the shares of Convertible Preferred Stock in any such appraisal proceeding.

(ix) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) pursuant to this Section IV.3(d), the Corporation at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Convertible Preferred Stock a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which the Convertible Preferred Stock is convertible) and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, as promptly as reasonably practicable after the written request at any time of any holder of Convertible Preferred Stock (but in any event not later than 10 days thereafter), furnish or cause to be furnished to such holder a certificate setting forth (i) the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) then in effect, and (ii) the number of shares of Series A Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the conversion of Convertible Preferred Stock.

(x) Notice of Record Date. In the event:

(A) the Corporation shall take a record of the holders of its Common Stock (or other capital stock or securities at the time issuable upon conversion of the Convertible Preferred Stock) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of capital stock of any class or any other securities, or to receive any other security; or

A-23

(B) of any capital reorganization of the Corporation, any reclassification of the Common Stock of the Corporation, or any Deemed Liquidation Event; or

then, and in each such case, the Corporation will send or cause to be sent to the holders of the Convertible Preferred Stock a notice specifying, as the case may be, (i) the record date for such dividend, distribution or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is proposed to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such other capital stock or securities at the time issuable upon the conversion of the Convertible Preferred Stock) shall be entitled to exchange their shares of Common Stock (or such other capital stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up, and the amount per share and character of such exchange applicable to the Convertible Preferred Stock and the Common Stock. Such notice shall be sent at least 10 days prior to the record date or effective date for the event specified in such notice.

(e) Mandatory Conversion.

(i) Trigger Events. Upon either (x) the closing of the sale of shares of Common Stock to the public at a price of at least 1.25 times the Series A Preferred Original Issue Price (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Common Stock) with aggregate gross proceeds, net of the underwriting discount and commissions, to the Corporation of not less than $100 million, in a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended, or (y) the date and time, or the occurrence of an event, specified by vote or written consent of the holders of at least 75% of the then outstanding shares of Series A Preferred Stock and Series B Preferred Stock (with the shares of Series A Preferred Stock and Series B Preferred Stock voting on an “as converted basis” as if such shares had been converted into Series A Common Stock pursuant to Section 1V.3(d) (whether or not such shares of Series B Preferred Stock are then convertible)) (the time of such closing, or the date and time specified or the time of the event specified in such vote or written consent is referred to herein as the “Mandatory Conversion Time”), then (A) upon an event specified in clause (x) or (y) above, all outstanding shares of Series A Preferred Stock and Series B Preferred Stock shall automatically be converted into shares of Series A Common Stock, in each case at the then effective conversion rate as calculated pursuant to Section IV.3(d)(i)(A) and (B) such shares of Series A Preferred Stock and Series B Preferred Stock converted pursuant to this Section IV.3(e)(i) may not be reissued by the Corporation.

A-24

(ii) Procedural Requirements. All holders of record of shares of Series A Preferred Stock and Series B Preferred Stock shall be sent written notice of the Mandatory Conversion Time and the place designated for mandatory conversion of all such shares of Series A Preferred Stock and Series B Preferred Stock pursuant to this Section 1V.3(e). Such notice need not be sent in advance of the occurrence of the Mandatory Conversion Time. Upon receipt of such notice, each holder of shares of Series A Preferred Stock and Series B Preferred Stock in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form reasonably satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Series A Preferred Stock and Series B Preferred Stock converted pursuant to Section IV.3(e)(i), including the rights, if any, to receive notices and vote (other than as a holder of Series A Common Stock), will terminate at the Mandatory Conversion Time (notwithstanding the failure of the holder or holders thereof to surrender any certificates at or prior to such time), except only the rights of the holders thereof, upon surrender of any certificate or certificates of such holders (or lost certificate affidavit and agreement) therefor, to receive the items provided for in the next sentence of this Section IV.3(e)(ii). As soon as practicable after the Mandatory Conversion Time and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for Series A Preferred Stock and Series B Preferred Stock, the Corporation shall (a) issue and deliver to such holder, or to his, her or its nominees, a notice of issuance of uncertificated shares and may, upon written request, issue and deliver a certificate for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof and (b) pay cash as provided in Section IV.3(d)(ii) in lieu of any fraction of a share of Series A Common Stock and Series B Preferred Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Series A Preferred Stock and Series B Preferred Stock converted. Such converted Series A Preferred Stock and Series B Preferred Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Series A Preferred Stock and Series B Preferred Stock accordingly.

(f) Redemption.

A-25

governing distributions to stockholders, shares of Series B Preferred Stock may be redeemed by the Corporation, in its sole and absolute discretion, at a price equal to the Series B Preferred Original Issue Price per share (the “Redemption Price”), and the date of such redemption shall be referred to as the “Redemption Date.” If on the Redemption Date Delaware law governing distributions to stockholders prevents the Corporation from redeeming all shares of Series B Preferred Stock to be redeemed, the Corporation shall ratably redeem the maximum number of shares that it may redeem consistent with such law, and shall redeem the remaining shares as soon as it may lawfully do so under such law. “Senior Notes” shall mean such notes set forth in the Indenture dated as of April 24, 2017, by and between the Corporation and Wilmington Trust, National Association, as Trustee and Collateral Trustee.

(ii) Redemption Notice. The Corporation shall send written notice of the redemption (the “Redemption Notice”) to each holder of record of Series B Preferred Stock not less than five (5) days prior to the Redemption Date. The Redemption Notice shall state:

(A) the number of shares of Series B Preferred Stock held by the holder that the Corporation shall redeem on the Redemption Date specified in the Redemption Notice;

(B) the Redemption Date and the Redemption Price;

(C) the date upon which the holder’s right to convert such shares terminates (as determined in accordance with Section IV.3(f)(iii)); and

(D) for holders of shares in certificated form, that the holder is to surrender to the Corporation, in the manner and at the place designated, his, her or its certificate or certificates representing the shares of Series B Preferred Stock to be redeemed.

(iii) Termination of Conversion Rights. In the event of a notice of redemption of any shares of Series B Preferred Stock pursuant to Section IV.3(f)(ii), the Conversion Rights of the shares of Series B Preferred Stock designated for redemption shall terminate at the close of business on the last full day preceding the Redemption Date, unless the Redemption Price is not fully paid on such Redemption Date, in which case the Conversion Rights for such shares of Series B Preferred Stock shall continue until such price is paid in full.

(iv) Surrender of Certificates; Payment. On or before the Redemption Date, each holder of shares of Series B Preferred Stock to be redeemed on the Redemption Date, unless such holder has exercised his, her or its right to convert such shares as provided in Section IV.3(d), shall, if a holder of shares in certificated form, surrender the certificate or certificates representing such shares (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to

A-26

indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation, in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price for such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof. In the event less than all of the shares of Series B Preferred Stock represented by a certificate are redeemed, a new certificate, instrument, or book entry representing the unredeemed shares of Series B Preferred Stock shall promptly be issued to such holder.

(v) Rights Subsequent to Redemption. If the Redemption Notice shall have been duly given, and if on the Redemption Date the Redemption Price payable upon redemption of the shares of Series B Preferred Stock to be redeemed on the Redemption Date is paid or tendered for payment or deposited with an independent payment agent so as to be available therefor in a timely manner, then notwithstanding that any certificates evidencing any of the shares of Series B Preferred Stock so called for redemption shall not have been surrendered, dividends with respect to such shares of Series B Preferred Stock shall cease to accrue after the Redemption Date and all rights with respect to such shares shall forthwith after the Redemption Date terminate, except only the right of the holders to receive the Redemption Price without interest upon surrender of any such certificate or certificates therefor.

(g) Redeemed or Otherwise Acquired Shares. Any shares of Series B Preferred Stock that are redeemed or otherwise acquired by the Corporation or any of its subsidiaries shall be automatically and immediately cancelled and retired and shall not be reissued, sold or transferred. Neither the Corporation nor any of its subsidiaries may exercise any voting or other rights granted to the holders of Series B Preferred Stock following redemption.

(h) Series B Preferred Stock Protective Provisions. At any time when at least fifty (50) percent of the shares of Series B Preferred Stock (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series B Preferred Stock) originally issued pursuant to the Series B Subscription Agreement are outstanding, the Corporation shall not, either directly or indirectly, without (in addition to any other vote required by law or the Certificate of Incorporation) the written consent or affirmative vote of the holders of at least fifty (50) percent of the then outstanding shares of Series B Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a class, and any such act or transaction entered into without such consent or vote shall be null and void ab initio, and of no force or effect:

(i) purchase, redeem or exchange or retire for value (or permit any subsidiary to purchase, redeem, exchange or retire for value) any shares of capital stock of the Corporation; or

(ii) pay or declare any dividend or make any distribution or payment on any shares of capital stock of the Corporation;

A-27

other than, in the case of clauses (i) and (ii), (x) redemptions of or dividends or distributions on the Series B Preferred Stock or (y) conversion of the Convertible Preferred Stock, in each case as expressly authorized herein.

A-4

Upon obtaining HSR Act Approval, each holder of outstanding shares of Series B Preferred Stock shall be entitled to cast the number of votes equal to the number of whole shares of Series A Common Stock into which the shares of Series B Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter (with the shares of Series B Preferred Stock voting on an “as converted basis” as if such shares had been converted into Series A Common Stock pursuant to Section IV.3(d) (whether or not such shares of Series B Preferred Stock are then convertible)).

A-15

A-16

A-17

CP₂ = CP₁* (A + B) ÷ (A + C).

A-18

For purposes of the foregoing formula, the following definitions shall apply:

(4) “B” shall mean the number of shares of Common Stock that would have been issued if such Additional Shares of Common Stock had been issued at a price per share equal to CP1 (determined by dividing the aggregate consideration received by the Corporation in respect of such issue by CP1); and

(5) “C” shall mean the number of such Additional Shares of Common Stock issued in such transaction.

(1) Cash and Property: Such consideration shall:

(I) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation, excluding amounts paid or payable for accrued interest;

(II) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and

A-19

(F) Multiple Closing Dates. In the event the Corporation shall issue on more than one date Additional Shares of Common Stock that are a part of one transaction or a series of related transactions and that would result in an adjustment to the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) pursuant to the terms of Section IV.3(d)(iv)(D), and such issuance dates occur within a period of no more than 90 days from the first such issuance to the final such issuance, then, upon the final such issuance, the Series A Preferred Conversion Price (in the case of the Series A Preferred Stock) or the Series B Preferred Conversion Price (in the case of the Series B Preferred Stock) shall be readjusted to give effect to all such issuances as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any such subsequent issuances within such period).

A-20

(A) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and

For the avoidance of doubt, nothing in this Section IV.3(d)(viii) shall be construed as preventing the holders of Convertible Preferred Stock from seeking any appraisal rights to which they are otherwise entitled under the DGCL in connection with a merger triggering an adjustment hereunder, nor shall this Section IV.3(d)(viii) be deemed conclusive evidence of the fair value of the shares of Convertible Preferred Stock in any such appraisal proceeding.

(x) Notice of Record Date. In the event:

(B) of any capital reorganization of the Corporation, any reclassification of the Common Stock of the Corporation, or any Deemed Liquidation Event; or

A-24

all such shares of Series A Preferred Stock and Series B Preferred Stock pursuant to this Section IV.3(e). Such notice need not be sent in advance of the occurrence of the Mandatory Conversion Time. Upon receipt of such notice, each holder of shares of Series A Preferred Stock and Series B Preferred Stock in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, any certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form reasonably satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Series A Preferred Stock and Series B Preferred Stock converted pursuant to Section IV.3(e)(i), including the rights, if any, to receive notices and vote (other than as a holder of Series A Common Stock), will terminate at the Mandatory Conversion Time (notwithstanding the failure of the holder or holders thereof to surrender any certificates at or prior to such time), except only the rights of the holders thereof, upon surrender of any certificate or certificates of such holders (or lost certificate affidavit and agreement) therefor, to receive the items provided for in the next sentence of this Section IV.3(e)(ii). As soon as practicable after the Mandatory Conversion Time and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for Series A Preferred Stock and Series B Preferred Stock, the Corporation shall (a) issue and deliver to such holder, or to his, her or its nominees, a notice of issuance of uncertificated shares and may, upon written request, issue and deliver a certificate for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof and (b) pay cash as provided in Section IV.3(d)(ii) in lieu of any fraction of a share of Series A Common Stock and Series B Preferred Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Series A Preferred Stock and Series B Preferred Stock converted. Such converted Series A Preferred Stock and Series B Preferred Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Series A Preferred Stock and Series B Preferred Stock accordingly.

(f) Redemption.

(i) General. At any time after the ninety-first (91^st) day after the earlier of the maturity date of the Senior Notes (as defined below) (but only if all obligations under the Senior Notes have been repaid in full on such date) or the date the Senior Notes are no longer outstanding, and unless prohibited by Delaware law governing distributions to stockholders, shares of Series B Preferred Stock may be redeemed by the Corporation, in its sole and absolute discretion, at a price equal to the Series B Original Issue Price per share (the “Redemption Price”), and the date

A-25

of such redemption shall be referred to as the “Redemption Date.” If on the Redemption Date Delaware law governing distributions to stockholders prevents the Corporation from redeeming all shares of Series B Preferred Stock to be redeemed, the Corporation shall ratably redeem the maximum number of shares that it may redeem consistent with such law, and shall redeem the remaining shares as soon as it may lawfully do so under such law. “Senior Notes” shall mean such notes set forth in the Indenture dated as of April 24, 2017, by and between the Corporation and Wilmington Trust, National Association, as Trustee and Collateral Trustee.

(A) the number of shares of Series B Preferred Stock held by the holder that the Corporation shall redeem on the Redemption Date specified in the Redemption Notice;

In the event less than all of the shares of Series B Preferred Stock represented by a certificate are redeemed, a new certificate, instrument, or book entry representing the unredeemed shares of Series B Preferred Stock shall promptly be issued to such holder.

In advance of any proposed Transfer of Sunnova Securities, other than an Exempt Transfer, the transferring Investor (the “Transferring Investor”) shall deliver written notice to the Company and each other Investor stating that the Transferring Investor desires to Transfer Sunnova Securities. Such notice (the “Transfer Notice”) shall be provided prior to the proposed Transfer and shall disclose the number of Sunnova Securities to be sold (the “Offered Securities”).

Section 3.3 Legending Requirement. Unless otherwise determined by the Board (upon advice from legal counsel), each certificate evidencing Sunnova Securities, if any, shall be stamped or otherwise imprinted with a legend containing substantially the following terms:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN INVESTORS AGREEMENT DATED AS OF NOVEMBER 9, 2017, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND THE COMPANY’S INVESTORS, AS THE SAME MAY BE AMENDED, SUPPLEMENTED AND/OR RESTATED FROM TIME TO TIME. THE TERMS OF SUCH INVESTORS AGREEMENT INCLUDE, AMONG OTHER THINGS, RESTRICTIONS ON TRANSFERS. A COPY OF SUCH INVESTORS AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

Section 3.4 Right of First Offer.

(a) At any time after the Lock-up Expiration Period, and subject to the terms and conditions specified in this Section 3.4, each Principal Investor shall have a right of first offer if any other Investor proposes to Transfer any Sunnova Securities owned by it to any third party, excluding Permitted Transferees. Each time the Transferring Investor proposes to Transfer any Offered Securities (other than Transfers to a Permitted Transferee and Transfers made pursuant to a Public Sale), the Transferring Investor shall first offer the Offered Securities to the Principal Investors (other than such Transferring Investor) in accordance with the provisions of this Section 3.4.

(b) The Transferring Investor shall provide a Transfer Notice to the Principal Investors stating its intention to Transfer the Offered Securities. Within thirty (30) days (the “Offer Period”) after receipt of the Transfer Notice by the Principal Investors, each Principal Investor, either alone or with one or more other Principal Investors, shall have a right to make an offer to purchase (i) all, but not less than all, of the Offered Securities or (ii) their Proportionate Percentage of Offered Securities (the “ROFO Offer”), provided that if the Transferring Investor is transferring greater than twenty-five percent (25%) of the Series A Common Stock (calculated on a fully-diluted as-converted basis), the ROFO Offer must be an offer to purchase all of the Offered Securities.

(c) Each ROFO Offer (i) shall set forth the proposed amount and form of consideration and terms and conditions of payment offered by the Investor or Investors and a summary of any other material terms pertaining to the Transfer and (ii) must remain open for at least sixty (60) days following the date on which the Transferring Investor receives the ROFO Offer.

(d) If the Transferring Investor does not receive any ROFO Offer within the Offer Period, or if all Principal Investors inform the Transferring Investor in writing that they will not be exercising their right of first offer rights hereunder, then the Transferring Investor may, subject to the requirements of Sections 3.4(h) and 3.6, transfer all of the Offered Securities to a third party at a price and on terms and conditions acceptable to such Transferring Investor.

(e) If the Transferring Investor receives only one ROFO Offer within the Offer Period, the Transferring Investor may accept or reject such ROFO Offer in its sole discretion. If the Transferring Investor receives more than one ROFO Offer for all of the Offered Securities, the Transferring Investor may accept the highest such ROFO Offer and reject the other ROFO Offers or reject all ROFO Offers in its sole discretion. If the Transferring Investor receives more than one ROFO Offer and at least one such ROFO Offer is for a Principal Investor’s Proportionate Percentage of the Offered Securities, the Transferring Investor may accept one or more of the highest ROFO Offer(s) and reject the other ROFO Offers or reject all ROFO Offers in its sole discretion; provided that, if the Transferring Investor accepts one or more Principal Investors’ ROFO Offers for their respective Proportionate Percentages of the Offered Securities, then the Company shall notify the remaining Principal Investors of such acceptance and the remaining Principal Investors shall have the opportunity to make a new ROFO Offer within five (5) Business Days of receipt of such notice from the Company for the Offered Securities which are not subject to any accepted ROFO Offer.

(f) If a Transferring Investor accepts a ROFO Offer, then the Transferring Investor and the applicable Principal Investor shall negotiate in good faith to consummate the ROFO Offer as promptly as reasonably practicable and in any event within sixty (60) days from the date of the ROFO Offer, and shall not transfer any Offered Securities described in such ROFO Offer to any third party purchaser.

(g) If the Transferring Investor rejects all ROFO Offers from the Principal Investors, or if the Transferring Investor does not accept ROFO Offers with respect to all Offered Securities, then the Transferring Investor may, subject to the requirements of Sections 3.4(h) and 3.6, sell any Offered Securities which are not subject to any accepted ROFO Offer to a third party purchaser at a price higher than that offered in all of the rejected ROFO Offers, and on such terms and conditions which, when taken as a whole, are at least as favorable in the aggregate to the Transferring Investor as those set forth in the most favorable rejected ROFO Offer.

(h) The Transferring Investor may only sell Offered Securities to a third party purchaser as permitted under Section 3.4(d) and Section 3.4(g), and the Transferring Investor shall:

(i) enter into a letter of intent or similar arrangement with such third party purchaser within sixty (60) days from the date that is the later of (x) the date of the last ROFO Offer and (y) the expiration of the Offer Period (such later date, the “Commencement Date”);

(ii) enter into a definitive agreement with such third party purchaser within one hundred twenty (120) days of the Commencement Date; and

(iii) consummate such sale within one hundred eighty (180) days of the Commencement Date; provided that to the extent the Transferring Investor has used commercially reasonable efforts to obtain all required approvals and consents prior to the expiration of such 180-day period, the Transferring Investor may extend such 180-day period by up to sixty (60) days if necessary to obtain any required regulatory approvals or third party consents.

(i) If the Transferring Investor does not meet any of the deadlines described in Section 3.4(h), then any proposed transfer by such Transferring Investor shall once again be subject to the terms and conditions of this Section 3.4.

(j) In the event of a potential sale by a Transferring Investor to a third party purchaser pursuant to the terms of Section 3.4(h), the directors and officers of the Company shall (i) permit such potential third party purchaser, after executing a confidentiality agreement in a form satisfactory to the Board, to conduct a due diligence review of the Company and its business, operations, prospects, assets, liabilities, financial condition and results of operations, and (ii) make available the officers and technical personnel of the Company, during normal business hours, upon reasonable advance notice and at such Transferring Investor’s sole cost and expense, for the purpose of making presentations to, and answering questions from, such potential third party purchaser.

Section 3.5 Drag-Along Right.

(a) After the Lock-up Expiration Date, except for any Transfer to a Permitted Transferee, if any Principal Investor or group of Principal Investors desires to make a Transfer of Sunnova Securities constituting seventy-five percent (75%) or more of the outstanding Series A Common Stock (on a fully-diluted, as-converted basis) to any third party and such Transferring Investor(s) has satisfied the requirements of Section 3.4, each remaining Investor (the “Drag-Along Investors”) shall, at the option of the Transferring Investor(s) (the “Drag-Along Right”), Transfer their Sunnova Securities (including Series B Common Stock issuable upon exercise of any Vested Options and any options that vest as a result of the consummation of the Transfer to the third party but not including any Series B Common Stock issuable upon exercise of any unvested Options) on the same terms and conditions as the Transfer of Offered Securities in the proposed Transfer (a “Drag-Along Sale”). The Company may require a Management Investor that is a Drag-Along Investor to exercise such Management Investor’s Vested Options, in whole or in part, prior to or simultaneously with the closing of any transaction or transactions described in this Section 3.5. If the Transferring Investor(s) elects to exercise its Drag-Along Right under this Section 3.5, then it shall so notify each Drag-Along Investor in writing (“Drag-Along Notice”). Each Drag-Along Notice shall (i) set forth the number of Offered Securities, (ii) specify in reasonable detail the identity of the Offeror, (iii) specify in reasonable detail the amount and type of consideration (including, if the consideration consists in whole or in part of non-cash consideration, such information available to the Transferring Investor as may be reasonably necessary for the Drag-Along Investors and the Company to properly analyze the economic value and investment risk of such non-cash consideration) and (iv) specify any other material terms and conditions of the proposed Transfer. Upon receipt of any Drag-Along Notice, each Drag-Along Investor shall, subject to the provisions of this Section 3.5, cooperate and use its commercially reasonable efforts to facilitate the Transfer and shall sign such instruments and take such action as may be reasonably required to consummate the Transfer. If, and only if, a Drag-Along Investor breaches the immediately preceding sentence and has not cured such breach within five (5) Business Days after receipt of written notice thereof from the Transferring Investor with a specific explanation of the alleged breach and the required corrective action (such notice a “Drag Breach Notice” and such Drag-Along Investor, a “Drag Breaching Investor”), then such Drag Breaching Investor is deemed to hereby make, constitute and appoint the Transferring Investor, with full power of substitution and re-substitution, as such Drag Breaching Investor’s true and lawful attorney-in-fact for it and in its name, place and stead and for its use and benefit, to sign, execute, certify, acknowledge, swear to, file and record any and all documents and to take any actions to the extent required to be taken by the Drag Breaching Investor pursuant to the immediately preceding sentence and set forth in the Drag Breach Notice. The parties hereto acknowledge that any such power of attorney is coupled with an interest and is irrevocable. Notwithstanding the foregoing, in the event that more than fifty percent (50%) of the proceeds to be received by the Drag-Along Investors is not cash, the Transferring Investor will not have the right to exercise the Drag-Along Right unless approved by a Board Supermajority.

(b) The proceeds of the Drag-Along Sale shall be allocated to the Transferring Investors and the Drag-Along Investors in accordance with Article IV.3(b) of the Restated Certificate as if (A) such transfer were a Deemed Liquidation Event (as defined in the Restated Certificate) and (B) the Offered Securities sold in accordance with this Section 3.5 were the only Sunnova Securities outstanding. For purposes of this Section 3.5(b), a Management Investor that

holds Vested Options that are not exercised prior to or simultaneously with the closing of the transaction shall receive, with respect to such Vested Options, the consideration that would otherwise be payable with respect to the shares of Series B Common Stock underlying such Vested Options, minus the aggregate exercise price of such Vested Options.

Section 3.6 Tag-Along Right.

(a) After the Lock-up Expiration Date, except for any Transfer to a Permitted Transferee and any proposed Transfer governed by Section 3.5, if any Investor or group of Investors desires to make a Transfer of (x) thirty-five percent (35%) or more, with respect to Tag-Along Rights of Principal Investors and (y) fifty percent (50%) or more, with respect to Tag-Along Rights of Management Investors, of the outstanding Series A Common Stock (on a fully-diluted as-converted basis) (as described herein, a “Tag-Along Sale”), each other Investor (a “Tag-Along Investor”) shall have the right (the “Tag-Along Right”) to require that the proposed purchaser in connection with the Tag-Along Sale purchase such Tag-Along Investor’s Proportionate Percentage of its Sunnova Securities (including Series B Common Stock issuable upon exercise of any Vested Options and any options that vest as a result of the consummation of the Transfer to the third party but not including any Series B Common Stock issuable upon exercise of any unvested Options) (the “Tag-Along Securities”), on the same terms and conditions as the Tag-Along Sale as set forth in the Transfer Notice, which, for purposes of this Section 3.6(a), shall (i) disclose the Offered Securities and (ii) specify in reasonable detail the amount and type of consideration (including, if the consideration consists in whole or in part of non-cash consideration, such information available to the Transferring Investor as may be reasonably necessary for the other Investors to properly analyze the economic value and investment risk of such non-cash consideration) and the other terms and conditions of the proposed Transfer. The Company may require a Management Investor that is a Tag-Along Investor to exercise such Management Investor’s Vested Options, in whole or in part, prior to or simultaneously with the closing of the transaction or transactions described in this Section 3.6. If a Tag-Along Investor elects to exercise its Tag-Along Right under this Section 3.6, then he, she or it shall so notify the Transferring Investor in writing (the “Tag-Along Notice”) within five (5) Business Days after the later of (i) the expiration of the Tag-Along Investor’s Offer Period, as applicable, and (ii) the last day on which the Transferring Investors are required to send notice of the exercise of Drag-Along Rights, if applicable. In the event that the purchaser in the Tag-Along Sale does not purchase all the Tag-Along Securities pursuant to this Section 3.6, then the Transferring Investor shall not be permitted to sell any of its Offered Securities to such purchaser unless the Transferring Investor purchases from the Tag-Along Investors all of the Tag-Along Securities, at the price and on comparable terms to what the Tag-Along Investors would have received if the purchaser in the Tag-Along Sale had purchased all such Tag-Along Securities.

(b) The proceeds of the Tag-Along shall be allocated to the Transferring Investors and the Tag-Along Investors in accordance with Article IV.3(b) of the Restated Certificate as if (A) such transfer were a Deemed Liquidation Event (as defined in the Restated Certificate) and (B) the Offered Securities sold in accordance with this Section 3.6 were the only Sunnova Securities outstanding. For purposes of this Section 3.6(b), a Management Investor that holds Vested Options that are not exercised prior to or simultaneously with the closing of the transaction shall receive, with respect to such Vested Options, the consideration that would otherwise be payable with respect to the shares of Series B Common Stock underlying such Vested Options, minus the aggregate exercise price of such Vested Options.

Section 3.7 Cooperation.

(a) In the event of (i) the exercise of a Drag-Along Right pursuant to Section 3.5, each Investor, or (ii) the exercise of a Tag-Along Right pursuant to Section 3.6, each Tag Along Investor exercising its Tag Along Right, shall consent to and raise no objections against the transaction and shall take all actions that the Board reasonably deems necessary or desirable in connection with the consummation of the transaction. Without limiting the generality of the foregoing, each such Investor agrees to: (A) execute any purchase agreement, merger agreement or other agreement entered into with the purchaser and any ancillary agreement with respect thereto; (B) vote the Sunnova Securities held by the Investor in favor of the transaction; and (C) refrain from the exercise of, and waive, dissenters’ appraisal rights with respect to the transaction.

(b) The obligations of the Drag-Along Investors and Tag-Along Investors are subject to the following terms and conditions:

(i) subject to Section 3.7(b)(v), if any Investor is given an option as to the form and amount of consideration to be received, all Drag-Along Investors or Tag-Along Investors, as applicable, shall be given the same option;

(ii) no Drag-Along Investor or Tag-Along Investor, as applicable, shall be required to provide any representations, warranties or indemnities in connection with the Transfer, other than customary (including with respect to qualifications) representations and warranties, subject to any exceptions set forth on a disclosure schedule, concerning (i) such Investor’s valid title to and ownership of the Sunnova Securities, free and clear of all Liens (excluding those arising under applicable securities laws), (ii) such Investor’s authority, power and right to enter into and consummate such Transfer, and (iii) the absence of any violation of law to which such Investor is subject or by which its assets are bound, which in each case shall be on a several basis, and not on a joint or joint and several basis; provided that such representations, warranties or indemnities shall not be required to be made or given unless the Transferring Investors make or give such representations, warranties or indemnities;

(iii) no Drag-Along Investor or Tag-Along Investor, as applicable, shall be liable for, or obligated with respect to, the inaccuracy of any representation, warranty or covenant made by another Person other than the Company in connection with the Transfer;

(iv) no Drag-Along Investor or Tag-Along Investor, as applicable, or any of its Affiliates (other than an Investor that is an employee or consultant of the Company or one or more of its Subsidiaries) shall be required to execute an agreement with a non-competition, non-solicitation, no-hire or other similar restrictive covenant provisions applicable to such Investor or any of its Affiliates, and any confidentiality provision shall be substantially similar to the confidentiality provision to which the Investors or any of their Affiliates is subject hereunder;

(v) unless otherwise approved by a Board Supermajority, no Drag-Along Investor or Tag-Along Investors, as applicable, will have any liability in respect of such Transfer for any breach in excess of its ratable share of any purchase price escrow, except for the Investor’s representations and warranties with respect to itself set forth in Section 3.7(b)(ii), which liability for breaches of such representation and warranties will not exceed the net purchase price actually received by such Investor, other than in the case of fraud;

(vi) any indemnification obligations will be on a several, and not joint, basis and a Drag-Along Investor’s or Tag-Along Investor’s, as applicable, aggregate liability will not exceed the net purchase price actually received by such Investor and shall be allocated among the Investors in a manner necessary to preserve the liquidation preference of the Convertible Preferred Stock, such that any such indemnification obligations shall be allocated first to the holders of Common Stock on a pro rata basis, with any remainder being allocated to the holders of the Convertible Preferred Stock on a pro rata basis, other than in the case of fraud; and

(vii) if all or part of the consideration proposed to be paid to Investors in a Transfer includes securities with respect to which no registration statement covering the issuance of such securities has been declared effective under the Securities Act, then each Investor that is not then an “accredited investor” (as such term is defined in Rule 501 under the Securities Act) may be required (notwithstanding Section 3.7(b)(i)), at the request and election of the Transferring Investor, to (i) appoint a purchaser representative (as defined in Rule 501 under the Securities Act) reasonably acceptable to such Transferring Investor or (ii) accept cash in lieu of any securities such Investor would otherwise receive in an amount equal to the fair market value of such securities. For the avoidance of doubt, any Transfer contemplated by this Section 3.7(b)(vii) that would result in any Drag-Along Investor receiving less than fifty percent (50%) of the aggregate consideration such Drag-Along Investor is entitled to receive under this Section 3.7(b)(vii) in a form other than cash must be approved by a Board Supermajority.

(c) Each Investor participating in a Drag-Along Sale or Tag-Along Sale shall bear its pro rata share of the costs of any transaction in which it sells Sunnova Securities (based upon the net proceeds received by such Investor in such transaction), allocated pro rata among the Investors in a manner necessary to preserve the liquidation preference of the Convertible Preferred Stock, such that any such costs shall be allocated first to the holders of Common Stock on pro rata basis, with any remainder being allocated to the holders of the Convertible Preferred Stock on a pro rata basis, to the extent such costs are incurred for the benefit of all holders of Sunnova Securities and are not otherwise paid by the Company or the acquiring party.

Section 3.8 Right to Public Offering.

(a) Pursuant to the Registration Rights Agreement dated as of the Original Agreement Date (as such agreement may be amended from time to time, the “Registration Rights Agreement”), by and among the Company and the Investors, certain Investors (the “IPO Investors”) shall have the right, upon the terms and subject to the conditions set forth in the Registration Rights Agreement and this Section 3.8, to cause the Company to consummate an initial public offering (a “Required IPO”).

(b) In furtherance of such Required IPO, the Company shall, upon written request of the IPO Investor(s), implement a structure for the Required IPO as determined by the IPO Investor(s) (the “Required IPO Structure”). The Company shall cooperate in the Required IPO Structure as requested by the IPO Investor(s).

(c) Anything contained herein to the contrary notwithstanding, if at any time the IPO Investor(s) exercise their rights pursuant to the Registration Rights Agreement to cause a Required IPO, each other Investor shall consent to and raise no objections to the Required IPO. The IPO Investor(s) shall provide to each other Investor a notice (the “IPO Notice”), at least forty-five (45) days prior to the consummation of the proposed Required IPO, setting forth the proposed terms of such Required IPO.

(d) Upon the delivery of such IPO Notice, each Investor shall take all necessary and desirable actions reasonably requested by the Board or the IPO Investor(s) in connection with the consummation of the Required IPO, including executing such documents (including any necessary amendments to this Agreement and the Registration Rights Agreement) and taking such other actions reasonably necessary to (i) establish the Required IPO Structure; (ii) provide customary representations, warranties and indemnities with respect to (A) matters of ownership and title to the Sunnova Securities owned by such Investors and (B) the due authorization or capacity and due and valid execution and delivery by such Investors of documentation in respect of the Required IPO, as are executed by the IPO Investors; (iii) provide indemnities, covenants, conditions, escrow agreements and other reasonable provisions and agreements relating to such Required IPO (it being understood and agreed that no Investor shall be required to enter into a non-competition covenant); and (iv) subject to Section 3.8(e), to pay its pro rata portion (based on participation in such Required IPO) of the fees and expenses incurred in connection with such Required IPO, provided that (x) each Investor that has a right to sell Sunnova Securities in such Required IPO and elects to sell Sunnova Securities in such Required IPO will receive the same form and amount of consideration per Sunnova Security, and (y) no Investor shall be required to incur indemnification obligations in connection with such Required IPO other than those set forth in the Registration Rights Agreement or the applicable underwriting agreement.

(e) Without limiting the foregoing, each Investor shall take all necessary actions reasonably requested by the Board or the IPO Investor(s) in connection with the consummation of such initial public offering, including, without limitation, (i) compliance with the requirements of all laws and regulatory bodies that have jurisdiction over such initial public offering, (ii) compliance with the listing and other rules governing the securities exchange on which the Common Stock will be listed and waiving any approval rights in connection with such initial public offering, provided that in no event shall any Investor be required to take any action which would be in violation of or contravene any law, rule, regulation or other limitation of any governmental or regulatory body having jurisdiction over such Investor as reasonably determined by such Investor’s legal counsel and (iii) taking such actions as may be necessary to effect a reorganization of the Company in anticipation of such initial public offering.

ARTICLE IV

PREEMPTIVE RIGHTS

Section 4.1 Sale of Securities.

(a) Except as set forth in Section 4.1(g), if the Company proposes to issue or causes to be issued (i) additional Sunnova Securities or any Securities of a Subsidiary of the Company (in each case other than Exempt Securities) or (ii) debt securities to any Investor or its Affiliates (determined without regard to the last sentence of the definition of “Affiliate”) (collectively, a “New Interest”), each Principal Investor shall have the right (the “Preemptive Right”), to purchase such Investor’s Proportionate Percentage of such New Interest at the time of the Preemptive Right Notice (defined below) and in accordance with the following procedures.

(b) The Company shall give each Principal Investor at least twenty (20) Business Days (the “Election Period”) prior written notice (the “Preemptive Right Notice”) of any proposed issuance of New Interests, which notice shall set forth in reasonable detail the proposed terms and conditions thereof and shall offer to each such Principal Investor the opportunity to purchase its Proportionate Percentage of such New Interests at the same price, on the same terms and conditions and at the same time as the New Interests are proposed to be issued by the Company. If any such Principal Investor wishes to exercise its Preemptive Right, it must do so by delivering an irrevocable written notice (an “Election Notice”) to the Company before the end of the Election Period, which notice shall set forth (i) the dollar amount of New Interests such Principal Investor desires to purchase in connection with such Preemptive Notice, up to such Principal Investor’s Proportionate Percentage (the “Preemptive Right Election Amount”) and (ii) if such Principal Investor desires to purchase more than its Proportionate Percentage, the maximum dollar amount of New Interests such Principal Investor desires to purchase (the excess of such maximum dollar amount over the dollar amount of such Principal Investor’s Proportionate Percentage, such Principal Investor’s “Additional Election Amount”) which such Additional Election Amount, together with the dollar amount of such Principal Investor’s Proportionate Percentage, shall not exceed the dollar amount of the New Interests being offered.

(c) If one or more of such Principal Investors entitled to the Preemptive Right fails to subscribe for all of its Proportionate Percentage (the New Interests that comprise any such unsubscribed portions of such Principal Investor’s Proportionate Percentage, the “Unsubscribed Amount”), the Company shall deliver written notice thereof (a “Supplemental Preemptive Notice”) to each Principal Investor that delivered an Election Notice requesting an Additional Election Amount (a “Preemptive Right Participating Principal Investor”), which notice shall set forth (i) the Unsubscribed Amount and (ii) the Additional Election Amount required to be funded by the Preemptive Right Participating Principal Investor based on its Election Notice, provided, however, that if the sum of all Additional Election Amounts of the Preemptive Right Participating Principal Investors set forth in the Election Notices exceeds the Unsubscribed Amount, then the Additional Election Amount of each Preemptive Right Participating Principal Investor shall be reduced to an amount equal to the product of (x) the Unsubscribed Amount and (y) a fraction (expressed as a percentage), the numerator of which is the amount of such Preemptive Right Participating Principal Investor’s Additional Election Amount and the denominator of which is the sum of all Additional Election Amounts requested by the Preemptive Right Participating Principal Investors in the Election Notices delivered to the Company pursuant to Section 4.1(b).

(d) At closing (which shall occur eleven (11) Business Days after the end of the Election Period or such other date as the Company and the Principal Investors who deliver an Election Notice pursuant to Section 4.1(b) may agree (such closing date, the “Preemptive Right Closing Date”)), each Principal Investor who delivers an Election Notice to the Company shall (i) purchase, for cash, the Preemptive Right Election Amount of New Interests indicated in the Election Notice of such Principal Investor, plus, if applicable, all or a portion of such Principal Investor’s Additional Election Amount of New Interests to the extent set forth in the Supplemental Preemptive Notice delivered to such Principal Investor pursuant to Section 4.1(c), and (ii) take all appropriate actions and execute such other instruments, in each case as shall be reasonably requested by the Company in connection with such New Interests. If any Principal Investor who delivers an Election Notice pursuant to Section 4.1(b) fails to make full payment to the Company on or prior to the Preemptive Right Closing Date for the purchase of its Preemptive Share Election Amount and Additional Election Amount (if any) of New Interests, as required under this Section 4.1(d), (a) such Principal Investor shall be entitled to purchase only such portion of its Preemptive Share Election Amount and Additional Election Amount (if any) covered by the dollar amount actually paid by such Principal Investor, (b) the portion of such Principal Investor’s Preemptive Share Election Amount and Additional Election Amount (if any) not so purchased shall be treated as an Unsubscribed Amount and the Company shall deliver a new Supplemental Preemptive Notice to each of the other Preemptive Right Participating Principal Investors with respect to such Unsubscribed Amount, (c) such Principal Investor’s election to purchase any additional New Interests pursuant to this Article IV shall be deemed null and void and (d) each other Principal Investor with a Preemptive Right any such additional New Interests not purchased (if any) shall be deemed to be part of the Unsubscribed Amount.

(e) If, following the end of the Election Period, there remains any Unsubscribed Amount that has not been subscribed for by one or more Principal Investors pursuant to Section 4.1(c) (or if following the Preemptive Right Closing Date there exists any Unsubscribed Amount), then for a period not exceeding one hundred eighty (180) days following the expiration of the Election Period (the “Third Party Offering Period”), any or all of such Unsubscribed Amount may be issued and sold to any purchaser at a price not less than the price at which they were offered to the Principal Investors and pursuant to other terms and conditions no more favorable in the aggregate to the purchasers thereof than those offered to the Principal Investors, in each case as specified in the Preemptive Right Notice. Any Unsubscribed Amount not so issued and sold to any purchaser during the Third Party Offering Period will thereafter again be subject to the Preemptive Rights provided for in this Article IV.

(f) If, in any instance, a Principal Investor elects not to exercise such Principal Investor’s rights under this Article IV, such election shall not constitute a waiver of such Principal Investor’s rights in the case of any subsequent transaction by the Company giving rise to the issuance of a Preemptive Right Notice hereunder.

(g) Notwithstanding anything herein in this Article IV to the contrary, if the Board determines that compliance with the time periods described in this Article IV would not be in the best interests of the Company because of the liquidity needs of the Company or to comply with covenants under any indebtedness of the Company, then, in lieu of offering any Sunnova Securities to the Principal Investors entitled to the Preemptive Right at the time such Sunnova Securities are otherwise being issued or sold to a purchaser of Sunnova Securities, the Company

may comply with the provisions of this Article IV by making an offer to sell to such Principal Investors their Proportionate Percentage (calculated as if the such Sunnova Securities had not been issued or sold) of the aggregate amount of such Sunnova Securities (including any Sunnova Securities offered pursuant to this Section 4.1(g)) promptly, and in no event later than thirty (30) Business Days, after such sale is consummated. In such event, for all purposes of this Article IV, each such Principal Investor’s Proportionate Percentage shall be determined taking into consideration the actual number of securities sold so as to achieve the same economic effect as if such offer would have been made prior to such sale.

(h) Notwithstanding anything in this Agreement to the contrary, any Principal Investor that is also a Management Investor shall lose his or her Preemptive Right on the date of such Management Investor’s Termination of Employment.

Section 4.2 Exempt Securities. The rights of the Investors under Section 4.1 shall not apply to the following Sunnova Securities (the “Exempt Securities”):

(a) Common Stock or Preferred Stock issued or issuable pursuant to the Purchase and Exchange Agreement (including pursuant to Section 9.2 thereof);

(b) Sunnova Securities issued by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock that is covered by Section IV.3(d)(v), (vi), (vii) or (viii) of the Restated Certificate;

(c) Sunnova Securities issued or issuable upon conversion of any of the Preferred Stock, or as a dividend or distribution on the Preferred Stock;

(d) Sunnova Securities issued or issuable upon the conversion of any debenture, warrant, option or other convertible security (but only to the extent that the original issuance of such debenture, warrant, option or other convertible security was subject to the preemptive rights set forth in this Section 4.1);

(e) Sunnova Securities issued or issuable to employees or directors of, or consultants or advisors to, the Company (including any Sunnova Securities issued upon the conversion, exercise or exchange thereof) pursuant to any plan approved by the Board;

(f) Sunnova Securities issued or issuable pursuant to the acquisition of another Entity by the Company by merger, purchase of substantially all of the assets or a business line, unit or division or other reorganization or pursuant to a joint venture agreement, provided that such issuances are approved by the Board;

(g) Any Securities of a Subsidiary of the Company issued to the Company or any Subsidiary of the Company; or

(h) Sunnova Securities issued or issuable in any firmly underwritten public offering of the Company pursuant to a registration statement under the Securities Act, including issuances solely for the purposes of effecting a Required IPO Structure in accordance with the terms of this Agreement and the Registration Rights Agreement.

ARTICLE V

RIGHTS TO REPURCHASE SHARES

Section 5.1 Call Right.

(a) The Company shall have the option to repurchase any Sunnova Securities held by any Management Investor or his or her Permitted Transferees (the “Call Right”), exercisable any time during the period beginning on the date of such Management Investor’s Termination of Employment and ending on the date (the “Repurchase Deadline”) that is the first anniversary of the later of (i) the date of such Termination of Employment and (ii) the date of the exercise of any Vested Options held by such Management Investor as of the date of such Termination of Employment; provided, however, that, notwithstanding the foregoing, in no event shall the Company purchase any Sunnova Securities pursuant to the Call Right prior to the day immediately following the six (6) month anniversary of the date such Management Investor first purchased such Sunnova Securities (whether pursuant to the exercise of Vested Options or otherwise). The Call Right may be exercised more than once and may be exercised with respect to some or all of the Sunnova Securities outstanding on the date of any Call Notice. The repurchase price payable by the Company upon exercise of the Call Right (“Call Repurchase Price”) shall be the Fair Market Value of the Sunnova Securities subject to the Call Right on the date of the repurchase; provided, however, that, notwithstanding the foregoing, in the event of (A) except for Management Investors’ Series A Common Stock or any Management Investors’ Series B Common Stock acquired prior to the date hereof, a Management Investor’s resignation prior to the second (or third, in the case of the Chief Executive Officer of the Company) anniversary of the later of the date hereof and such Management Investor’s date of hire by the Company, (B) a Management Investor’s Termination of Employment at any time by the Company for Cause or (C) material breach by a Management Investor of any restrictive covenant (other than a nondisparagement covenant) in any employment agreement, Equity Incentive Plan or equity award agreement or other document to which such Management Investor is subject (“Restrictive Covenants”), the Call Repurchase Price shall be the lesser of (x) Fair Market Value of the Sunnova Securities subject to the Call Right on the date of the repurchase and (y) the purchase price paid by such Management Investor for such Sunnova Securities (or if no purchase price was paid, the price per Sunnova Security equal to the par value per Sunnova Security); provided, further, that a resignation of a Management Investor for Good Reason as defined in and pursuant to such Management Investor’s employment agreement with the Company shall be deemed to be a Termination of Employment by the Company or without Cause for purposes of determining the Call Repurchase Price. The Call Right shall be exercised by written notice to the Management Investor given in accordance with Section 10.4 of this Agreement (a “Call Notice”) on or prior to the Repurchase Deadline.

(b) In addition, the Company shall have a Call Right effective immediately prior to any Sale of the Company to occur following the date hereof. For purposes of the exercise of any such Call Right, the determination of Fair Market Value shall be made without regard to any discounts for illiquidity or lack of control.

(c) In the event that the Company elects not to exercise its Call Right under Section 5(a) with respect to all of the Sunnova Securities then held by a Management Investor or his or her Permitted Transferees (the “Eligible Shares”), (i) the Company shall provide written notice to the ECP Investors on or at any time prior to the Repurchase Deadline of (A) the

Company’s decision not to purchase all of the Eligible Shares and (B) the number of Eligible Shares that were not purchased by the Company and (ii) the ECP Investors, for so long as the ECP Investors collectively own 40% (or, following the ECP Investors’ satisfaction of their commitment to purchase the full number of the Additional Shares, 50%) or more of the outstanding Series A Common Stock (on a fully-diluted as-converted basis), shall have the option to purchase some or all of such Eligible Shares (the “ECP Call Right”) at the Call Repurchase Price; provided that a Board Adjustment Event has not occurred. The ECP Call Right shall be exercised by a Call Notice on or prior to the later of (x) the thirtieth (30th) day following receipt by the ECP Investors of the written notice under clause (i) above and (y) the Repurchase Deadline.

(d) Subject to Section 5.3 below, the repurchase of Sunnova Securities pursuant to the exercise of a Call Right or ECP Call Right shall take place on a date specified by the Company or the ECP Investors, as applicable, but in no event following the later of (i) the sixtieth (60th) day following the date of the Call Notice and (ii) if applicable, the tenth (10th) day following the receipt by the Company of all necessary governmental approvals. On such date, the Management Investor or his or her Permitted Transferees shall transfer the Sunnova Securities subject to the Call Notice to the Company or the ECP Investors, as applicable, free and clear of all liens and encumbrances, by delivering the certificates representing the Sunnova Securities to be purchased, duly endorsed for transfer to the Company or the ECP Investors, as applicable, or accompanied by a stock power duly executed in blank, and the Company or the ECP Investors, as applicable, shall pay to such Management Investor the Call Repurchase Price. The Management Investor shall use all commercially reasonable efforts to assist the Company or the ECP Investors, as applicable, in order to expedite all proceedings described in this Article 5.

Section 5.2 Involuntary Transfers.

(a) In the case of any transfer of title or beneficial ownership of Sunnova Securities upon default, foreclosure, forfeit, divorce, court order or otherwise, other than by a voluntary decision on the part of a Management Investor (each, an “Involuntary Transfer”), such Management Investor shall promptly (but in no event later than two (2) days after the Involuntary Transfer) furnish written notice (the “Involuntary Transfer Notice”) to the Company indicating that the Involuntary Transfer has occurred, specifying the name and last known address, phone number, facsimile number and email address of the person to whom the shares were transferred (the “Involuntary Transferee”), giving a detailed description of the circumstances giving rise to, and stating the legal basis for, the Involuntary Transfer.

(b) Upon the receipt of the Involuntary Transfer Notice, and for sixty (60) days thereafter, the Company shall have the right to repurchase, and the Involuntary Transferee shall have the obligation to sell, any of the Sunnova Securities acquired by the Involuntary Transferee for a repurchase price equal to the Fair Market Value of such Sunnova Securities as of the date of the repurchase (the “Involuntary Transfer Repurchase Price” and such right, the “Involuntary Transfer Repurchase Right”). The Involuntary Transfer Repurchase Right shall be exercised by written notice (the “Involuntary Transfer Repurchase Notice”) to the Involuntary Transferee given in accordance with Section 10.4 of this Agreement on or prior to the last date on which the Involuntary Transfer Repurchase Right may be exercised by the Company. The Involuntary Transfer Repurchase Right may be exercised more than once and may be exercised with respect to some or all of the Sunnova Securities.

(c) In the event that the Company elects not to exercise its Involuntary Transfer Repurchase Right under Section 5.2(b) with respect to all of the Sunnova Securities, (i) the Company shall provide written notice to the ECP Investors on or at any time prior to sixtieth (60^th) day after receipt of the Involuntary Transfer Notice of (A) the Company’s decision not to purchase all of the Sunnova Securities acquired by the Involuntary Transferee and (B) the number of Sunnova Securities that were not purchased by the Company and (ii) the ECP Investors, for so long as the ECP Investors collectively own 40% (or, following the ECP Investors’ satisfaction of their commitment to purchase the full number of the Additional Shares, 50%) or more of the outstanding Series A Common Stock (on a fully-diluted as-converted basis), shall have the option to purchase, and the Involuntary Transferee shall have the obligation to sell, some or all of such Sunnova Securities (the “ECP Involuntary Transfer Repurchase Right”) at the Involuntary Transfer Repurchase Price; provided that a Board Adjustment Event has not occurred. The ECP Involuntary Transfer Repurchase Right shall be exercised by delivery of an Involuntary Transfer Repurchase Notice on or prior to the thirtieth (30th) day following receipt by the ECP Investors of the written notice under clause (A) above. The ECP Involuntary Transfer Repurchase Right may be exercised more than once and may be exercised with respect to some or all of the Sunnova Securities.

(d) Subject to Section 5.3 below, the repurchase of Sunnova Securities pursuant to the exercise of the Involuntary Transfer Repurchase Right or ECP Involuntary Transfer Repurchase Right shall take place on a date specified by the Company or the ECP Investors, as applicable, but in no event following the later of the sixtieth (60^th) day following the date of the Involuntary Transfer Repurchase Notice or the tenth (10^th) day following the receipt by the Company of all necessary governmental approvals. On such date, the Involuntary Transferee shall transfer the Sunnova Securities subject to the Involuntary Transfer Repurchase Notice to the Company or the ECP Investors, as applicable, free and clear of all liens and encumbrances, by delivering the certificates representing the Sunnova Securities to be purchased, duly endorsed for transfer to the Company or the ECP Investors, as applicable, or accompanied by a stock power duly executed in blank, and the Company or the ECP Investors, as applicable, shall pay the Involuntary Transfer Repurchase Price to the Involuntary Transferee. The Involuntary Transferee shall use all commercially reasonable efforts to assist the Company or the ECP Investors, as applicable, in order to expedite all proceedings described in this Section 5.2. If the Involuntary Transferee does not transfer the Sunnova Securities to the Company as required, the Company will cancel such Sunnova Securities and deposit the funds in a non-interest bearing account and make payment upon delivery.

(e) In addition to the restrictions set forth elsewhere in this Agreement, if the Company and the ECP Investors do not elect to purchase all of the Sunnova Securities pursuant to the exercise of the Involuntary Transfer Repurchase Right and the ECP Involuntary Transfer Repurchase Right, respectively, the Involuntary Transferee shall agree in writing to be bound by the terms and conditions of this Agreement pursuant to an instrument of assumption reasonably satisfactory in form and substance to the Board. Upon the execution of an instrument of assumption by such Involuntary Transferee, such Involuntary Transferee shall be deemed to be a Management Investor for all purposes of this Agreement except that Article 5 shall cease to apply following such Transfer (other than Section 5.2, which shall continue to apply). If the Involuntary Transferee fails to execute an instrument of assumption in accordance with this Section 5.2(e) within thirty (30) days of receiving notice from the Company, the Company shall have the option to repurchase

some or all of the Sunnova Securities held by the Involuntary Transferee for Fair Market Value at any time upon notice to the Involuntary Transferee, and if the Involuntary Transferee fails to transfer any such Sunnova Securities to the Company, the Company will cancel such Sunnova Securities and deposit the funds in a non-interest bearing account and make payment upon delivery.

Section 5.3 Repurchase Disability.

(a) Notwithstanding anything to the contrary herein, except as otherwise provided by Section 5.3(c), the Company shall not be permitted to purchase any Sunnova Securities held by any Management Investor or Involuntary Transferee upon exercise of the Call Right or the Involuntary Transfer Repurchase Right if the Board determines that:

(i) the purchase of Sunnova Securities would render the Company or its Subsidiaries unable to meet their obligations in the ordinary course of business taking into account any pending or proposed transactions, capital expenditures or other budgeted cash outlays by the Company, including, without limitation, any proposed acquisition of any other entity by the Company or any of its Subsidiaries;

(ii) the Company is prohibited from purchasing the Sunnova Securities by applicable law restricting the purchase by a corporation of its own shares; or

(iii) the purchase of Sunnova Securities would constitute a breach of, default, or event of default under, or is otherwise prohibited by, the terms of any loan agreement or other agreement or instrument to which the Company or any of its Subsidiaries is a party (the “Financing Documents”) or the Company is not able to obtain the requisite consent of any of its senior lenders to the purchase of the Sunnova Securities.

The events described in (i) through (iii) above each constitute a “Repurchase Disability.”

(b) Except as otherwise provided by Section 5.3(c), in the event of a Repurchase Disability, the Company shall notify in writing the Management Investor or Involuntary Transferee with respect to whom the Call Right or the Involuntary Transfer Repurchase Right has been exercised (a “Disability Notice”). The Disability Notice shall specify the nature of the Repurchase Disability. The Company shall thereafter repurchase the Sunnova Securities described in the Call Notice or Involuntary Transfer Repurchase Notice as soon as reasonably practicable after all Repurchase Disabilities cease to exist (or the Company may elect, but shall have no obligation, to cause its nominee to repurchase the Sunnova Securities while any Repurchase Disabilities continue to exist). In the event the Company suspends its obligations to repurchase the Sunnova Securities pursuant to a Repurchase Disability: (i) the Company shall provide written notice to each applicable Management Investor or Involuntary Transferee as soon as practicable after all Repurchase Disabilities cease to exist (the “Reinstatement Notice”); (ii) the Fair Market Value of the Sunnova Securities subject to the Call Notice or Involuntary Transfer Repurchase Notice shall be determined as of the date the Reinstatement Notice is delivered to the Management Investor or Involuntary Transferee, which Fair Market Value shall be used to determine the Call Repurchase Price or Involuntary Transfer Repurchase Price in the manner described above; and (iii) the repurchase shall occur on a date specified by the Company within ten (10) days following the determination of the Fair Market Value of the Sunnova Securities to be repurchased as provided in clause (ii) above.

(c) Notwithstanding Section 5.3(a) and Section 5.3(b), in the event of a Repurchase Disability, then, in the sole discretion of the Board, the Company may purchase the Sunnova Securities subject to the Call Right or Involuntary Transfer Repurchase Right, as applicable, and, in lieu of cash consideration, issue a promissory note to such Management Investor in the amount of the Call Repurchase Price or Involuntary Transfer Purchase Price, as applicable, the terms of which promissory note shall be acceptable to the Company’s senior lenders and shall not result in a breach or violation of any of the Financing Documents. The promissory note shall (i) bear compound interest at the prime rate as published in the Wall Street Journal on the date such payment is due and owing from such date to the date such payment is made, (ii) have a term of no more than three (3) years and (iii) have such other reasonable terms and conditions as may be determined by the Company. All payments of interest accrued under the promissory note shall be paid only at the date of payment by the Company of the principal amount of such promissory note.

Section 5.4 Set-Off. If any Management Investor is determined by final judicial determination (or final determination of binding arbitration) to have materially breached any Restrictive Covenant following the exercise by the Company or the ECP Investors of the Call Right or the ECP Call Right, respectively, then such Management Investor shall immediately return any Gain realized with respect to the Sunnova Securities repurchased by the Company or the ECP Investors pursuant to the Call Right or the ECP Call Right. For purposes of this Agreement, “Gain” shall mean an amount equal to the excess, if any, of the Call Repurchase Price for the Sunnova Securities repurchased over the purchase price, if any, paid by such Management Investor for such Sunnova Securities. Each Management Investor consents to a deduction (to the extent permitted by applicable law and not prohibited by Section 409A of the Code) from any amounts the Company or any of its Affiliates may owe such Management Investor from time to time (including, without limitation amounts owed to such Management Investor as wages or other compensation, fringe benefits or vacation pay), to the extent of the amounts such Management Investor owes the Company pursuant to this Section 5.4. Whether or not the Company elects to make any set-off in whole or in part, if the Company does not recover by means of set-off the full amount owed by a Management Investor pursuant to this Section 5.4, such Management Investor shall immediately pay the unpaid balance to the Company.

(1) At such time as the ECP Investors (together with their Permitted Transferees) fail to hold Sunnova Securities representing more than thirty percent (30%) of the Series A Common Stock of the Company (calculated on a fully-diluted as-converted basis), then the ECP Investors shall be entitled to designate two (2) ECP Directors (with Energy Capital Partners III, LP and Energy Capital Partners III-D, LP losing their rights to designate a director) and the Non-ECP Lead Investor Group, on behalf of the Non-ECP Investors, shall be entitled to designate five (5) Non-ECP Directors.

Section 8.1 Certain Tax Matters.

(a) If reasonably requested by any Investor in writing, the Company shall within a reasonable period of time provide such Investor with a duly executed statement pursuant to Treasury Regulation Section 1.897-2(h) informing such Investor whether or not the Sunnova Securities held by such Investor constitute a “United States real property interest” (and shall comply with the related notice requirements in Treasury Regulation Section 1.897-2(h)(2)).

(b) The Company hereby agrees not to treat the Preferred Stock as “preferred stock” for purposes of Section 305 of the Code.

The Company shall prepare and file all tax information reports and other returns in a manner consistent with this Section 8.1(b).

(d) Each Investor agrees to provide the Company from time to time with any information available to such Investor that is reasonably requested by the Company and reasonably necessary for the Company to determine whether the Company is a “tax-exempt” controlled entity within the meaning of Section 168(h)(6)(F)(iii) of the Code. Notwithstanding the foregoing, it is understood and agreed that (i) no Investor will be required by the previous sentence to provide any information that is not in its possession at the time such Investor receives the request from the Company and (ii) no Investor has a duty under this Section 8.1(d) to make inquiries of its direct or indirect owners.

Upon the Transfer in accordance with the terms of this Agreement by any Investor of all Sunnova Securities owned by such Investor, such Investor shall have no further rights or privileges under this Agreement or otherwise be entitled to the benefits hereof.

This Agreement (including the Exhibits hereto), the Restated Certificate, the Restated Bylaws and the other Transaction Agreements contain the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings relating to such subject matter. No party shall be liable or bound to any other party in any manner by any representations, warranties or covenants relating to such subject matter except as specifically set forth in this Agreement (including the Exhibits hereto), the Restated Certificate, the Restated Bylaws and the other Transaction Agreements.

Section 10.2 Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

Section 10.3 Amendments; Waivers.

(a) Except as expressly set forth herein, the provisions of this Agreement may only be amended with the prior written consent of the Requisite Investors; provided, however, that the Company may update Schedule I from time to time, without consent, to reflect Transfers of Sunnova Securities made in accordance with this Agreement, and the Company will, from time to time, distribute to the Investors a revised Schedule I to reflect any such updates; provided, further, that the Company may enter into one or more Joinder Agreements to reflect Transfers permitted by this Agreement; provided, further that (i) any amendment that by it terms affects the rights or obligations of any Principal Investor in a manner that is materially adverse to such Principal Investor and substantially different relative to the other Investors shall require the written consent of such Principal Investor and (ii) the prior written consent of the Company shall be required, in the event that any such amendment imposes a burden or obligation on the Company or adversely affects a benefit or right of the Company under this Agreement.

(b) Any waiver, permission, consent or approval of any kind or nature by any party hereto, of any breach or default under this Agreement, or any waiver of any provision of this Agreement by any party hereto, must be in writing and shall be effective only in the specific instance and for the specific purpose given, and shall be effective only to the extent in such writing specifically set forth, and the same shall not operate or be construed as a waiver of any subsequent breach, default, provision or condition of this Agreement by any party hereto, including the party to whom originally given. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Section 10.4 Notices. All notices or other communications required or permitted to be given hereunder shall be in writing and shall be deemed effectively given upon the earlier of actual receipt, or (a) when so delivered by hand, (b) when sent, if sent by electronic mail or facsimile during normal business hours of the recipient, and if not sent during normal business hours, then on the recipient’s next business day, (c) if by registered or certified mail, return receipt requested, postage prepaid, three days after mailing or (d) one (1) Business Day after deposit with a nationally recognized overnight courier, freight prepaid, specifying next Business Day delivery, with written verification of receipt, as follows or to such other address as shall be given in writing by any party to the other:

If to the Company, to:

Sunnova Energy Corporation

20 East Greenway Plaza, Suite 475

Houston, Texas 77046

Attention: Chief Executive Officer

If to an Investor, to the address set forth on Schedule I, or to such other address as the Party to whom such notice or other communication is to be given may have furnished to each other Party in writing in accordance herewith.

Each of the ECP Investors has designated the ECP Representative to act as its representative with respect to the making of, and the delivery and receipt of, all notices, elections, approvals, requests or other instructions or determinations (each, a “Notice”) and to otherwise act on behalf of any or all of the ECP Investors with respect to any Notices delivered in connection with this Agreement. The ECP Investors shall cause the ECP Representative to act at the direction of the ECP Investors holding a majority of Sunnova Securities (calculated on a fully-diluted as-converted basis) held by all of the ECP Investors with respect to all such Notices. Each of the Company and the other Investors shall direct any Notice to be made to any ECP Investor to the ECP Representative and agree that any Notice delivered under this Agreement by the ECP Representative shall be deemed to be a Notice delivered by the ECP Investors. Any Notice made to the ECP Representative (referencing the ECP Investors) shall be deemed to have been made to the ECP Investors in the form and at the time made to the ECP Representative.

Section 10.5 Equitable Remedies. The Sunnova Securities are agreed to be unique, and recognizing that the remedy at law for any breach or threatened breach by a party hereto of the covenants and conditions set forth herein would be inadequate, and further recognizing that any such breach or threatened breach would cause immediate, irreparable and permanent damage to the parties, the extent of which would be impossible or difficult to ascertain, the parties hereto agree that in the event of any such breach or threatened breach, and in addition to any and all remedies at law or otherwise provided herein, any party hereto may specifically enforce the terms of this Agreement and may obtain temporary and/or permanent injunctive relief (including a mandatory injunction) without the necessity of proving actual damage or the lack of an adequate remedy at law and, to the extent permissible under applicable rules, provision and statutes, a temporary injunction may be granted immediately upon the commencement of any suit hereunder regardless of whether the breaching party or parties have actually received notice thereof. Such remedy shall be cumulative and not exclusive, and shall be in addition to any other remedy or remedies available to the parties.

Section 10.6 Confidentiality. Each Investor agrees to, and shall instruct its Affiliates, directors, officers, employees, agents, advisors and representatives (“Representatives”) to, hold confidential, and not knowingly and deliberately use in any manner detrimental to the Company or any of its Subsidiaries, all information they may have or obtain concerning the Company or any of its Subsidiaries and their respective assets, business, operations, financial performance or

prospects or the arrangements among the Investors and the Company (“Confidential Information”), provided, however, that the term “Confidential Information” does not include information that (a) is already in such party’s possession, provided that such information is not subject to another confidentiality agreement with or other obligation of secrecy to any Person known to such party, (b) is or becomes generally available to the public other than as a result of a disclosure, directly or indirectly, by such party or such party’s Representatives, (c) is or becomes available to such party on a non-confidential basis from a source other than any of the parties hereto or any of their respective Representatives, provided that such source is not known by such party to be bound by a confidentiality agreement with or other obligation of secrecy to any Person or (d) is developed by such Person without the use of Confidential Information, provided further, however, that nothing herein shall prevent any party hereto from disclosing Confidential Information (i) upon the order of any court or administrative agency, (ii) upon the request or demand of any regulatory agency or authority having jurisdiction over such party, (iii) to the extent required by law or regulation (it being understood and agreed that, in the case of clause (i), (ii) or (iii), unless prohibited by law, regulation or any regulatory authority or in the case of required periodic disclosure under applicable securities laws, to the extent not prohibited by applicable law, such party shall notify the other parties hereto of the proposed disclosure as far in advance of such disclosure as practicable and use reasonable efforts to ensure that any information so disclosed is accorded confidential treatment, when and if available), (iv) to the extent necessary in connection with any suit, action or proceeding relating to this Agreement or the exercise of any remedy hereunder, (v) to such party’s Representatives that need to know such information and who agree to keep such information confidential on the terms set forth in this Section 10.6, (vi) to potential purchasers of the Company or of the Sunnova Securities held by an Investor, (vii) to potential investors in connection with fundraising purposes on the part of an Investor (or its controlling equity holder or any Person who manages, advises or sub-advises such Investor), (viii) to the limited partners, investors or other direct or indirect equity owners of, or prospective investors of, such party or its Affiliates or its or their Representatives or (ix) to the current or prospective financing sources of an Investor, provided that, prior to disclosing any Confidential Information to a potential purchaser or investor pursuant to clauses (vi), (vii), (viii) or (ix), such potential purchaser or investor will have entered into a customary confidentiality agreement. Notwithstanding the foregoing, in the event that an Investor instructs its Representatives to comply with this Section 10.6 and such Representative fails to comply, the Investor shall be fully liable for any breach of this Section 10.6 by its Representatives as though committed by the Investor itself. The obligations of each Investor under this Section 10.6 shall terminate on the one (1) year anniversary of first to occur of (I) the date such Investor ceases to be a party to this Agreement and (II) the termination of this Agreement.

Section 10.7 Public Announcements. Each party hereto will coordinate in good faith any and all press releases and other public relations matters with respect to this Agreement, the Purchase and Exchange Agreement and the transactions contemplated hereby and thereby. Unless otherwise required by law or the rules of any stock exchange or regulatory authority, no party hereto may issue any press release or otherwise make any public announcement or comment on this Agreement, the Purchase and Exchange Agreement or the transactions contemplated hereby or thereby without prior written consent of the Requisite Investors, provided that unless otherwise required by law or the rules of any stock exchange or regulatory authority no such press release, public announcement or comment shall identify any Investor or its Affiliates or otherwise make any public statement with respect to any Investor or its Affiliates without the prior written consent

of such Investor; provided, further that nothing in this Section 10.7 shall prohibit the Investors or any of their Affiliates or Representatives from making disclosures of customary information regarding the transactions contemplated by this Agreement, the Investors’ investment in the Company, the financial performance and operations of the Company and its Subsidiaries and such other information relevant to the Investors’ investment in the Company to the limited partners, investors or other direct or indirect equity owners of, or prospective investors of, the Investors or their Affiliates who are under customary duties or obligations of confidentiality.

Section 10.8 Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without regard to the conflicts of law principles of such State. The parties (a) hereby irrevocably and unconditionally submit to the jurisdiction of the courts of the State of Delaware sitting in New Castle County and to the jurisdiction of the United States District Court sitting in Wilmington, Delaware for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the courts of the State of Delaware sitting in New Castle County or the United States District Court sitting in Wilmington, Delaware and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

Section 10.9 WAIVER OF JURY TRIAL. EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION AGREEMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF.

THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS.

Section 10.14 Other Interpretive Matters. For purposes of this Agreement, (a) when calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period is excluded, and if the last day of such period is a non-Business Day, the period in question ends on the next succeeding Business Day, (b) unless the context otherwise requires, all references in this Agreement to any “Article,” “Section” or “Exhibit” are to the corresponding Article, Section or Exhibit of this Agreement, (c) the word “including,” or any variation thereof, means “including, without limitation” and does not limit any general statement that it follows to the specific or similar items or matters immediately following it and (d) all references to dollar amounts are expressed in United States Dollars.

Section 10.17 Attorneys’ Fees.

Section 10.18 Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of any similar breach or default thereafter occurring, nor shall any waiver

of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.

Section 10.21 Offsets. The Company shall be permitted, to the extent not prohibited by Section 409A of the Code, to offset and reduce from any amounts payable to a Management Investor the amount of any indebtedness or other obligation or payment owing to the Company by the Management Investor.

SUBORDINATED CONVERTIBLE PROMISSORY NOTE

(Bridge Loan Note – Sunnova)

$15,000,000.00 (plus any amounts owing in respect of PIK Interest as set forth on Schedule I)

Effective as of August 25, 2017

New York, New York

FOR VALUE RECEIVED, Sunnova Energy Corporation, a Delaware corporation (“Maker”), having a notice address of 20 E. Greenway Plaza, Suite 475, Houston, Texas 77046, hereby promises to pay pursuant to this promissory note (this “Note”) to Energy Capital Partners III, LP, Energy Capital Partners III-A, LP, Energy Capital Partners III-B, LP, Energy Capital Partners III-C, LP and Energy Capital Partners III-D, LP (collectively, the “Holders” and, each individually, a “Holder”), on the earlier of (i) the first date on which all of the 12.00% Senior Secured Notes due 2018 (the “2018 Notes”) issued pursuant to the Indenture, dated as of April 24, 2017 (the “Indenture”), by and between the Company and Wilmington Trust, National Association, as trustee (the “2018 Notes Trustee”) and collateral trustee, have been repaid in full and are no longer outstanding, and (ii) November 30, 2018 (such date being referred to as the “Maturity Date”), the principal amounts set forth on Schedule I hereto next to each such Holder’s name, together with any and all accrued and unpaid interest on such outstanding principal amounts; provided, that, notwithstanding the foregoing all amounts payable hereunder shall become immediately due and payable upon (x) the institution of, or material development under, bankruptcy proceedings under the U.S. Bankruptcy Code or similar proceedings under state or federal law with respect to the Maker (subject to the Subordination Provisions (as defined below)) or (y) the initial funding under the Facility (as defined below); provided further, that, all amounts outstanding under the 2018 Notes are repaid and all obligations thereunder are extinguished in full in connection and contemporaneously with such initial funding.

Interest shall accrue from the effective date hereof until the entire balance is paid (or converted, as provided below) on the unpaid principal balance of this Note at the interest rate (“Interest Rate”) of twelve percent (12%) per annum. Interest shall be paid quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, until and including the Maturity Date, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent Interest Payment Date or, if no interest has been paid, from the date of issuance. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. At all times prior to the repayment of the 2018 Notes, interest shall be payable solely by increasing the then outstanding principal amount of this Note by the entire amount of the interest payment due on the applicable Interest Payment

Date (“PIK Interest”). Following an increase in the principal amount of this Note on the applicable Interest Payment Date by the amount of the PIK Interest, this Note will bear interest on such increased principal amount from and after such Interest Payment Date. For clarity, unless the context otherwise requires, references to any principal amount of this Note includes any increase in the principal amount of this Note as a result of the payment of PIK Interest. Upon the occurrence of the Maturity Date, all unpaid principal, accrued interest and other amounts owing hereunder shall be immediately due, payable and collectible by the Holders pursuant to applicable law. This Note shall not, under any circumstances, be payable in cash, except on and after the repayment in full of the 2018 Notes.

Notwithstanding any provision to the contrary herein, Maker may not, at any time, prepay all or any portion of this Note, except in connection with (x) any conversion into shares of the Company’s Convertible Preferred Stock pursuant to the terms hereof or (y) repayment in connection and contemporaneously with the initial funding of the Facility (as defined in the term sheet attached hereto as Exhibit A) pursuant to the terms hereof.

Unless earlier converted, on and after the Maturity Date, an amount equal to the principal amount of this Note and any accrued and unpaid interest, in each case, as of the Maturity Date, shall be payable in lawful money of the United States of America and in immediately available funds at the office of each Holder set forth on Schedule I, unless another place of payment shall be specified in writing by a Holder to Maker. Notwithstanding the foregoing, upon and subject to the affirmative written election of the Majority Holders (as defined below) delivered to the Maker not later than five (5) business days prior to the date of conversion, the entire balance then outstanding hereunder shall be converted into that number of shares of the Company’s Convertible Preferred Stock as is equal to (i) an amount equal to the principal amount of this Note and any accrued and unpaid interest, in each case, as of the date of conversion, divided by (ii) the lesser of $5.3246735 (as appropriately adjusted for any stock splits, combinations, recapitalizations or the like affecting the Convertible Preferred Stock after the date hereof) and the Conversion Price.

For purposes of this Note, the term “Conversion Price” shall mean an amount equal to the lowest purchase price per share of Convertible Preferred Stock issued at any time from and after the date of this Note and until the date of conversion.

In the event that any balance of this Note is converted into shares of the Company’s Convertible Preferred Stock pursuant to the terms hereof, (x) each Holder’s outstanding commitments under the Subscription Documents for Convertible Preferred Stock of the Company, dated April 24, 2017, by and between such Holder and the Company (the “Subscription Agreements”), shall be deemed reduced to the amount equal to (i) the applicable Aggregate Purchase Price (as defined in the Subscription Agreements) minus (ii) the initial principal balance of this Note (not including any increase thereto in respect of PIK Interest) held by such Holder and repaid pursuant to such conversion and (y) the number of shares of Convertible Preferred Stock subject to such Subscription Agreements shall be reduced by a number of shares of Convertible Preferred Stock equal to the initial principal balance of this Note (not including any increase thereto in respect of PIK Interest) repaid pursuant to such conversion divided by $5.3246735 (as appropriately adjusted for any stock splits, combinations, recapitalizations or the like affecting the Convertible Preferred Stock after the date hereof), rounded down.

Anything in this Note to the contrary notwithstanding, the Maker hereby covenants and agrees, and the Holders likewise hereby covenant and agree, that the indebtedness and all other obligations, whether now or hereafter outstanding, of the Maker under this Note (the “Subordinated Debt”) shall be junior and subordinate to the extent and in the manner set forth in clauses (a) through (m) below (collectively, the “Subordination Provisions”) to the Maker’s Obligations (as defined in the Indenture), whether now or hereafter outstanding with respect to the 2018 Notes and related documents (the “Senior Indebtedness”).

(a) The Subordinated Debt is subordinated in all respects and subject in right of payment to the Senior Indebtedness such that the (i) payment in full, in cash of the principal of and interest and fees (including interest and fees accruing during the pendency of any insolvency or liquidation proceeding) regardless of whether allowed or allowable in an Insolvency Proceeding (as defined below) on the Senior Indebtedness and regardless of whether then due or payable and (ii) payment in full, in cash of all other Senior Indebtedness that is then due and payable or otherwise accrued and owing at or prior to the time such principal and interest are paid (including any contingent indemnification obligations to the extent then asserted) (the “Payment in Full”) of the Senior Indebtedness shall occur before any Holder is entitled to receive any payment or distribution on account of the Subordinated Debt of assets, properties or cash of Maker or any other person of any kind or character, whether (A) a payment, purchase or other acquisition or retirement for cash, property or securities (other than PIK Interest in respect of this Note) or (B) by way of cancellation, forgiveness or offset of the indebtedness owing by Maker against any indebtedness owed by any Holder or (C) payable or deliverable by reason of the payment of any other indebtedness of Maker being subordinated to the payment of this Note and, in any case, shall include any assets of any kind or character received by the Holders in connection with the realization of any security for this Note (each, a “Distribution”) (including interest (other than PIK Interest)) on account of the Subordinated Debt and, in that connection, unless and until the Payment in Full of the Senior Indebtedness occurs, no payment or Distribution (including interest (other than PIK Interest)) with respect to this Note shall be made by or on behalf of the Maker; provided, that, nothing in this clause (a) or any other provision of this Note shall be construed to prohibit the refinancing, replacement or repayment of all or any portion of the unpaid principal balance of this Note with (or the conversion of all of any portion of the unpaid principal balance of this Note into) common or non-”disqualified preferred” (as customarily defined) equity interests of Maker. No Holder shall initiate or cooperate or join with any other person in any proceeding challenging (1) the validity or enforceability of any documents in connection with the Senior Indebtedness or any indebtedness governed thereby, (2) any payment or distribution received by any holder of Senior Indebtedness or any agent therefor (each, a “Senior Debtholder”) for application to all or any part of the Senior Indebtedness or (3) the existence, validity, perfection or priority of any actual or purported lien claimed by any Senior Debtholder in any collateral or any other property in which Maker has rights from time to time.

(b) In the event of any insolvency, bankruptcy or receivership case or proceeding or any dissolution, winding up, liquidation, reorganization or other similar proceedings relative to Maker or its assets (whether voluntary or involuntary and whether in bankruptcy, insolvency or receivership proceedings or otherwise) or upon an assignment

for the benefit of creditors, or any other marshaling of the assets of Maker or its assets (each of the foregoing, an “Insolvency Proceeding”), then Payment in Full shall occur before the Holders shall be entitled to receive or retain any payment or Distribution (including interest (other than PIK Interest)) with respect to this Note. In any such proceedings, any payment or Distribution (including interest (other than PIK Interest)) to which the Holders would be entitled if this Note and the Subordinated Debt were not subordinated to the Senior Indebtedness shall be paid by the Maker or by the agent or other person making such payment or distribution, or by the Holders if and to the extent received by the Holders, directly to the 2018 Notes Trustee to be allocated as set forth in the terms of the Senior Indebtedness or if not so allocated, pro rata based on the outstanding principal amount thereof. Following commencement of and during the continuance of an Insolvency Proceeding, each of the Holders may (i) prove its claim or, if applicable, its interest, in the Subordinated Debt, (ii) file any necessary responsive or defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading objecting to, or otherwise seeking the disallowance of, the amounts due under this Note or otherwise impairing any of the Holders’ rights under this Note or, except as otherwise limited or prohibited by the Subordination Provisions, file any motions pertaining to the Subordinated Debt, and (iii) vote on any plan of reorganization or other dispositive plan that is consistent with the rights and priorities of the Senior Debtholders under the Subordination Provisions. Nothing in this clause (b) or any other provision of this Note shall be construed to prohibit the refinancing, replacement or repayment of all or any portion of the amounts due under this Note with (or the conversion of all of any portion of the amounts due under this Note into) common equity or non-”disqualified preferred” equity interests of Maker pursuant to this clause (b).

(c) Until the Payment in Full of Senior Indebtedness, if any Holder receives any payment or Distribution (including interest but excluding PIK Interest) in respect of the Subordinated Debt, then such payment or Distribution shall be promptly paid over or delivered to 2018 Notes Trustee with any necessary endorsement and the payment shall be deemed never to have been made in respect of the Subordinated Debt.

(d) The Holders shall not exercise any rights or remedies under this Note, including, without limitation, any action (A) to take from or for the account of the Maker or any other person, by set-off or in any other manner, the whole or any part of any moneys which may now or hereafter be owing by the Maker or any such person with respect to the Senior Indebtedness or the Subordinated Debt (including but not limited to the amounts due on account of this Note), (B) to sue for payment of the Senior Indebtedness or the Subordinated Debt, or to initiate or participate with others in any suit, action or proceeding against the Maker or any other person to (i) enforce payment of or to collect the whole or any part of the amounts due with respect to the Senior Indebtedness or the Subordinated Debt or (ii) commence judicial enforcement of any of the rights and remedies under the 2018 Notes (or other applicable loan or credit agreement) or applicable law with respect to the Senior Indebtedness or under this Note or applicable law with respect to the amounts due hereunder or thereunder, (C) to accelerate the Senior Indebtedness (or any portion thereof) or the Subordinated Debt (or any portion thereof), (D) to cause the Maker to honor any redemption or mandatory prepayment obligation related to this Note, or (E) to take any action under the provisions of any state or federal law, including, without limitation, the

Uniform Commercial Code, or under any contract or agreement, to enforce, foreclose upon, take possession of or sell any property or assets of the Maker or any other person, including the collateral securing the Senior Indebtedness (each, an “Enforcement Action”), until Payment in Full has occurred. Notwithstanding anything in this Note to the contrary, whether or not any Senior Indebtedness is outstanding: (1) the Holders may file proofs of claim and statements of interest against Maker in any Insolvency Proceeding in a manner consistent with the Subordination Provisions; (2) the Holders may take any action required to toll the expiration of any statute of limitation; and (3) take any other actions to preserve or protect the validity and enforceability of rights of the Holders with respect to the Subordinated Debt not expressly prohibited in these Subordination Provisions. Any distributions or other proceeds of any Enforcement Action obtained by or for the benefit of the Holders shall in any event be held in trust by it for the benefit of the 2018 Notes Trustee and promptly paid or delivered to the 2018 Notes Trustee in the form received until Payment in Full has occurred.

(e) Until Payment in Full, each Holder hereby acknowledges and agrees that any Senior Debtholder may at any time and from time to time without the consent of or notice to any Holder, and without incurring responsibility to any Holder or impairing or releasing the subordination provided in the Subordination Provisions or the obligations hereunder of any Holder to any Senior Debtholder, do any one or more of the following: (i) extend, renew, modify, waive or amend the terms of any Senior Indebtedness; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any guarantor or any other person liable in any manner for Senior Indebtedness or amend or waive the terms of any guaranty of Senior Indebtedness; (iv) exercise or refrain from exercising any rights against Maker or any other person; (v) apply any sums by whomever paid or however realized to Senior Indebtedness; (vi) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding or secured; and (vii) take any other action which otherwise might be deemed to impair the rights of the Senior Debtholders. Any and all of such actions may be taken by the Senior Debtholders without incurring responsibility to any Holder and without impairing or releasing the obligations of any Holder to the Senior Debtholders.

(f) Any subsequent Holder of this Note agrees, by its acceptance hereof, that obligations of the Maker hereunder are junior and subordinate to the Senior Indebtedness to the extent and in the manner set forth in the Subordination Provisions.

(g) No right of any present or future Senior Debtholder to enforce subordination as provided in the Subordination Provisions will at any time in any way be prejudiced or impaired by any act or failure to act on the part of Maker or by any act or failure to act, in good faith, by any Senior Debtholder, or by any noncompliance by Maker with the terms of this Note regardless of any knowledge thereof that any such Senior Debtholder may have or otherwise be charged with. The Subordination Provisions are intended to be for the benefit of, and shall be enforceable directly by, the 2018 Notes Trustee or any Senior Debtholder, and no other person other than the 2018 Notes Trustee, any Senior Debtholder or the parties hereto shall have or be entitled to assert rights or benefits hereunder.

(h) Until Payment in Full, so long as any Senior Indebtedness is outstanding, in the event that any Holder shall fail to file a proof of claim following any Insolvency Proceeding of Maker within 5 days prior to the deadline to file proofs of claim in the applicable Insolvency Proceeding, such Holder shall irrevocably appoint the 2018 Notes Trustee as its attorney in fact, and grant the 2018 Notes Trustee a power of attorney with full substitution, in the name of Holder, for the use and benefit of the Senior Debtholders, to file such proof of claim on its behalf in connection with such Insolvency Proceeding.

(i) Until Payment in Full, if, in any Insolvency Proceeding, debt obligations of the reorganized debtor secured by liens upon any property of the reorganized debtor are distributed, pursuant to a plan of reorganization or similar dispositive restructuring plan, on account of both the Senior Indebtedness and the Subordinated Debt, then, to the extent the debt obligations distributed on account of the Senior Indebtedness and on account of the Subordinated Debt are secured by liens upon the same assets or property, the Subordination Provisions will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the liens securing such debt obligations.

(j) Following the Payment in Full of the Senior Indebtedness, the Holders shall be subrogated to the rights of the Senior Debtholders (or their agent or representative) to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of, and interest on, and all other amounts in respect of, the Subordinated Debt shall be paid in full; however, such right of subrogation shall not be exercised as to any collateral or other property acquired prior to Payment in Full by the 2018 Notes Trustee, the Senior Debtholders or their respective affiliates in connection with an Enforcement Action or an Insolvency Proceeding. For purposes of such subrogation, no payments or distributions to the Senior Debtholders (or their agent or representative) of any cash, property or securities to which the Holders would be entitled except for these Subordination Provisions, and no payments over pursuant to these Subordination Provisions to the Senior Debtholders (or their agent or representative) by the Holders, shall be deemed to be a payment or distribution by Maker to or on account of the Senior Indebtedness except to the extent constituting such a payment or distribution pursuant to the terms of the Indenture or constituting a Payment In Full; it being understood and agreed that the Subordination Provisions are solely for the purpose of defining the relative rights of the Senior Debtholders (or their agent or representative) on the one hand, and the Holders on the other hand.

(k) Until Payment in Full has occurred, no amendment or waiver of any provision of this Note, shall directly or indirectly (s) modify the Subordination Provisions, (t) increase the Interest Rate in respect of the Subordinated Debt, (u) shorten the scheduled final maturity of the Subordinated Debt, (v) modify the principal repayment or prepayment provisions of the Subordinated Debt in a manner that would require a repayment or prepayment not required as of the date hereof, (w) change any covenants, defaults, or events of default (including the addition of covenants, defaults, or events of default not contained in the Note as in effect on the date hereof) to restrict Maker from making payments in respect of any Senior Indebtedness, (x) increase the principal balance of the Subordinated Debt (other than as a result of the accrual of interest, accretion or the payment of PIK Interest pursuant to the terms of the Note as in effect as of the date hereof), or (y)

convert the payment of any accrual or PIK Interest to cash pay interest, in each case, without the prior written consent of the 2018 Notes Trustee and each of the Senior Debtholders. Until Payment in Full has occurred, Maker shall not grant (and no Holder shall accept the benefit of) a lien or security interest on any collateral to secure any portion of the Subordinated Debt.

(l) For the avoidance of doubt, nothing herein shall: (i) impair, as between the Maker and the Holders, the obligation of the Maker, which is absolute and unconditional, to pay principal of and interest on the Note as set forth herein; or (ii) affect the relative rights of the Holders and creditors of the Maker other than their rights in relation to the Senior Debtholders.

The 2018 Notes Trustee shall not be deemed to owe any fiduciary duty to the Holders as a result of this Note and the 2018 Notes Trustee shall not be liable to any Holder of Notes if it shall pay over or deliver to holders of the 2018 Notes, the Issuer or any other Person money or assets which are delivered to the 2018 Notes Trustee hereunder.

Any waiver shall be in writing and effective against a Holder if signed by the applicable Holder. No delay or omission on the part of the Holders in exercising any right shall operate as a waiver of such right or any other right. A waiver on any one occasion shall not be construed as a bar to or waiver of any right on any future occasion. All rights and remedies of the Holders with respect to this Note and the obligations hereunder, whether evidenced hereby or by any other instrument or papers, shall be cumulative and may be exercised singularly, alternatively, successively or concurrently at such time or at such times as the Holders deems expedient.

The Holders shall not have the right to transfer or assign any of their rights or obligations under this Note without the prior written consent of the Maker and any proposed assignment or transfer without consent shall be void ab initio; provided, however, that transfers or assignments of this Note (but not increases in principal amount, other than as the result of PIK Interest) shall be permitted (a) to holders of Series A Common Stock or Convertible Preferred Stock that is required pursuant to Section 4.1(g) of that certain Investors Agreement, dated as of March 16, 2016, by and among the Maker and certain other parties thereto (the “Investors Agreement”) or (b) to Energy Capital Partners III (Sunnova Co-Invest), LP or any other Permitted Transferee, as defined in and in accordance with the Investors Agreement.

This Note and all obligations of Maker hereunder shall be binding upon the successors and assigns of Maker, and shall, together with the rights and remedies of the Holders, inure to the benefit of each Holder, any future holder of any of the indebtedness and their respective successors and assigns. This Note may be amended by the Maker and Holders holding a majority of the then outstanding principal amount under this Note (the “Majority Holders”). Notwithstanding the foregoing, the Interest Rate and Maturity Date cannot be amended without the written consent of all Holders and the principal amount owed to a Holder under this Note cannot be amended without such Holder’s written consent.

The Maker and the Holders intend to comply at all times with applicable usury laws. If at any time such laws would render usurious any amounts due under this Note under applicable law, then it is Maker’s and the Holders’ express intention that (i) the Maker not be required to pay interest on this Note at a rate in excess of the maximum lawful rate, (ii) that the provisions of this paragraph shall control over all other provisions of this Note which may be in apparent conflict hereunder, (iii) that such excess amount shall be immediately credited to the principal balance of this Note, and (iv) the provisions hereof shall immediately be reformed and the amounts thereafter decreased, so as to comply with the then applicable usury law, but so as to permit the recovery of the fullest amount otherwise due under this Note.

THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. Maker agrees that any suit for the enforcement of this Note may be brought in the courts of the State of New York or any federal court sitting therein and consents to the non-exclusive jurisdiction of such court and to service of process in any such suit being made upon Maker by mail at the address specified in the first paragraph of this Note (or such other address as Maker may provide written notice of to the Holders). Maker hereby waives any objection that it may now or hereafter have to the venue of any such suit or any such court or that such suit is brought in an inconvenient court.

EACH PARTY HERETO WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS NOTE, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS OR OBLIGATIONS. Except as prohibited by law, Maker waives any right which it may have to claim or recover in any litigation referred to in the preceding sentence any special, exemplary, punitive or consequential damages or any damages other than, or in addition to, actual damages. Each party (i) certifies that neither the other parties nor their respective representatives, agents or attorneys has represented, expressly or otherwise, that such party would not, in the event of litigation, seek to enforce the foregoing waivers and (ii) acknowledges that, in entering into this Note, each party is relying upon, among other things, the waivers and certifications contained in this Note.

If any term of this Note shall be held to be invalid, illegal or unenforceable, the validity of all other terms hereof shall in no way be affected thereby, and this Note shall be construed and be enforceable as if such invalid, illegal or unenforceable term had not been included herein. This Note may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Note by facsimile or by electronic portable document format shall be effective as delivery of a manually executed counterpart of this Note.

IN WITNESS WHEREOF, the Maker has executed and delivered this Note on August 25, 2017.

Disqualified		Each entity listed as a “Disqualified Lender”, as provided in writing by the Borrower to Ares Mgmt and Melody

Lender:		prior to the Closing Date and on each anniversary of the Closing Date.

Initial Commitments:		$135 million by ARCC; $65 million by Melody

Facility:		The principal terms of the Term Loan (“TL” or “Facility”) are outlined below:

Commitment:		$200 million, fully funded on the Closing Date; $50 million under the Incremental Facility

Incremental Facility:		For 18 months following the Closing Date, the Borrower may elect by written notice to the Arrangers (the “Increase Notice”) to increase the Commitment by $50 million to be funded in not more than two draws (such amount, the “Incremental Facility”), subject to the satisfaction of the following conditions: (i) no event of default exists or would exist after giving effect to any such increase, (ii) the representations and warranties in the Facility shall be accurate in all material respects after giving effect to any

such increase, (iii) subject to the following paragraph, receipt of additional commitments from the Lenders or one or more other financial institutions, and (iv) the Lenders shall have received all organizational documents (including resolutions of the Borrower and any guarantors) it may reasonably request relating to the corporate or other necessary authority for such increase and the validity of such increase, and other organizational matters relevant thereto, all in form and substance reasonably acceptable to the Lenders. Borrower may not elect to increase the Commitment within 90 days of the Closing Date.

Until the date that is 30 days after receipt of an Increase Notice (“ROFR Period”), the Arrangers shall have a right of first refusal to participate in the Incremental Facility. During the ROFR Period, the Borrower and its affiliates may not seek commitments from new lenders (the “New Lenders”). After the ROFR Period, the Borrower and its affiliates may seek commitments from New Lenders. If the Incremental Facility is not closed within 120 days of the receipt of the Increase Notice, the ROFR Period is thereby reinstated.

If the Arrangers elect to participate in the Incremental Facility, (x) an upfront fee/OID equal to [***]% of the Incremental Facility shall be paid to each Arranger in the Incremental Facility based on their pro rata commitment, (y) the Interest Rate applicable to the Incremental Facility shall remain as set forth below and (z) the Warrants issued to the Arrangers shall be as described below.

Subject to the following bullets, the Incremental Facility shall have the same terms and conditions as the Facility¹²

• If the Incremental Facility includes a higher upfront fee/OID, the Arrangers shall be paid (x) the difference of such upfront fee/OID and [***]%, multiplied by (y) the Commitment; provided that the New Lenders shall not be paid an upfront fee/OID greater than [***]% of the Incremental Facility commitment.

• If the Incremental Facility includes a higher interest rate, such higher interest rate shall apply to the Facility with respect to the original Commitment, but there will be no change in the Minimum Cash Interest (as it relates to the Facility).

¹	NOTE: For the avoidance of doubt, incremental lenders which are New Lenders shall not have any right or flexibility to modify any term except for Fees, Interest Rate and Warrants.

NOTE: For simplicity, “Arrangers” is used to mean the Lenders on the Closing Date in the “Incremental Facility” and “Warrant” sections of this term sheet . To the extent the Arrangers syndicate post-closing, the “true-ups” will be appropriately adjusted between the Arrangers and the lenders to whom the Arrangers syndicated.


		• If the Incremental Facility grants more Initial Warrants to the New Lenders (on a per dollar of commitment basis) than were granted to the Arrangers on the Closing Date, the Arrangers shall receive additional Initial Warrants (on a per dollar of commitment basis) pro rata in an amount equal to the difference between the amount of additional Initial Warrants granted to the New Lenders and the amount of Initial Warrants granted to the Arrangers on the Closing Date. • If the Incremental Facility grants more Additional Warrants to the New Lenders (on a per dollar of commitment basis) than the amount set on the Closing Date to be granted to the Arrangers, the amount of Additional Warrants entitled to be received by the Arrangers shall be increased (on a per dollar of commitment basis) to match the amount granted to the New Lenders. The cap of 6.0% will also be increased proportionately.³

Closing Date:		September 5, 2017

Upfront Fee/OID:		[***]% of the Commitment to be funded on the Closing Date to be paid to the Lenders as of the Closing Date, based on their pro-rata commitment

Tenor:		4.5 years

Interest Rate:		12.0%

Payment Date:		Quarterly for interest and scheduled principal amortization

Minimum Cash		Minimum cash interest based on the below schedule:


Date		Minimum Cash Interest

Prior to 12/31/18		[***]%

Following 12/31/18		[***]%

PIK Option:

Borrower may exercise the PIK option subject to:

i. Satisfying the Minimum Cash Coupon

ii. No event of default exists

iii. The total outstanding balance of the TL not exceeding 120% of the total funded amount

iv. No occurrence or continuation of Turbo Amortization (i.e. PIK allowed during the 120-day Liquidity Cure Period, however, failure to cure the Liquidity Breach will eliminate eligibility of the PIK Option).

³	NOTE: Sunnova confirms the excel example sent by Ares on August 1; to be reflected in definitive documents.


Administrative Agent Fee:		$[***] per annum, payable in advance in equal quarterly installments

Mandatory Amortization:		Mandatory amortization based on the below schedule, to be paid quarterly:


Date		Mandatory Amortization
Prior to 6/30/19		None

6/30/19		[***]% of draws

9/30/19		[***]% of draws

12/31/19		[***]% of draws

3/31/20		[***]% of draws

6/30/20		[***]% of draws

9/30/20		[***]% of draws

12/31/20		[***]% of draws

3/31/21		[***]% of draws

6/30/21		[***]% of draws

9/30/21		[***]% of draws


Prepayment Premium:		In the event the principal repayments and Interest received by the Lenders (excluding, for purposes of calculating the Prepayment Premium, Upfront Fee/OID, Default Interest, and gains associated with the Warrants) result in a return on investment to the Lender below the Minimum ROI, then upon repayment or prepayment of the Term Loan (including upon acceleration), the Borrower will make a true-up payment such that the Lender, after taking the true-up payment into account, will achieve the Minimum ROI on cumulative drawn amounts on the Facility. The Prepayment Premium will be calculated and paid at the earlier of maturity of the Facility and the repayment in full in cash of the Facility.

Minimum ROI:		1.40


Warrant:		Initial Warrant

		On the Closing Date, the Arrangers will be issued warrants to purchase 2% of the Conv Pref of NewCo on a fully-diluted basis as of date of exercise, at an exercise price of $0.01 per share, which will have a 7-year term from the Closing Date and will be exercisable in part or in full at any time during such term. If ECP converts its Conv Pref to common stock, such warrants shall become exercisable into common stock (or dragged into common stock if ECP coverts after the Arrangers have exercised their warrants for Conv Pref). For the avoidance of doubt, only the Arrangers shall be allocated Initial Warrants. If the Arrangers participate in the Incremental Facility, the Arrangers will be issued additional warrants on the foregoing terms to purchase an additional 0.5% of the Conv Pref of NewCo on a fully-diluted basis as of date of exercise, at an exercise price of $0.01 per share, which will have a 7-year term from the Closing Date and will be exercisable in part or in full at any time during such term.

		Additional Warrants

		On each anniversary of the Closing Date until the Maturity Date (or the earlier repayment of the Loans in full), then-current Lenders will be granted on a pro rata basis additional warrants to purchase 1.0% (or, if the Arrangers have participated in the Incremental Facility, 1.25%) of the Conv Pref of NewCo at an exercise price of $0.01 per share, which will have a 7-year term from the Closing Date and will be exercisable in part or in full at any time during such term; provided, that, in no event shall the Initial Warrants and the Additional Warrants granted in connection with the Facility exceed 6.0% of the Conv Pref of NewCo (or, if the Arrangers have participated in the Incremental Facility, 7.5% and subject to increase if the Incremental Facility grants more Additional Warrants to the New Lender). For the avoidance of doubt, Additional Warrants shall only be granted to then-current Lenders who are Lenders with respect to the original Commitment, unless the Borrower has agreed separately to grant Additional Warrants to New Lenders with respect to the Incremental Facility.

		Springing Warrant

		In the event of an Event of Default that has not been cured for 180 days, then-current Lenders will be issued, on a pro-rata basis based on outstanding Term Loans owing to such lenders, an additional warrant to purchase 5.0% of the Conv Pref of NewCo on a fully diluted basis as of date of exercise, at an exercise price of $0.01 per share (the “Springing Warrants” and, collectively with the Initial Warrant and the Additional Warrants, the “Warrants”).


		The Springing Warrants will have a 7-year term (from the Closing Date) and will be exercisable in part or in full at any time during such term.

		Subject to the following sentence, the Springing Warrants shall be reduced to 0% of the Conv Pref of NewCo if the Borrower achieves Goldman Success (as defined below) within 6 months of the Closing Date. If the Springing Warrants have been reduced to 0% as a result of achieving Goldman Success, the Springing Warrants will be reinstated (on the original terms) in the event of a Warehouse CoC Violation (as defined in Appendix A).

		“Goldman Success” means any of the following (a) amending the AP6 facility (i) to eliminate or modify (such modification to be reasonably satisfactory to the Lenders) the standstill requirement with respect to the pledge of Sunnova Asset Portfolio 6 Holdings, LLC (“AP6H”), Sunnova Asset Portfolio 6, LLC (“AP6”), Sunnova AP 6 Warehouse II, LLC (“AP6 Warehouse”) (provided that failure to eliminate or modify such standstill requirement as it relates to AP6 and AP6 Warehouse shall not prevent the reduction of Springing Warrants to 0% of Conv Pref of NewCo) and Borrower and (ii) to eliminate the change of control with respect to foreclosure on equity in AP6H, AP6, AP6 Warehouse (provided that failure to eliminate such change of control requirement as it relates to AP6 and AP6 Warehouse shall not prevent the reduction of Springing Warrants to 0% of Conv Pref of NewCo) and Borrower (which can be subject to customary limitations (such as transferee satisfying creditworthiness and operational requirements)); for the avoidance of doubt, an amendment substantially similar to the provisions negotiated in the amendments to the SSA/SLA Warehouse Facilities as of the Closing Date would satisfy this clause (a)(ii)), or (b) refinancing the AP6 facility and opening a new warehouse on similar terms whereby the change of control triggers are subject to customary limitations (such as transferee satisfying creditworthiness and operational requirements).

		Warrant-holder Rights (all Warrants)

		The Warrants will have, among other things: (i) information rights that are equivalent to the TL, and (ii) customary minority protections substantially equivalent to the rights of the non-ECP investors.

		The Warrants will also be subject to weighted average anti-dilution protection on substantially the same terms as the Convertible Preferred Stock, which protection shall apply on a post-exercise basis.

Use of Proceeds:		To repay the Magnetar notes, pay fees and expenses incurred in connection with the Facility, deposit cash with Borrower and Parent to achieve the balances set forth in clause (iii) of the Conditions Precedent, to repay a $15 million shareholder loan and thereafter for general corporate purposes. Incremental facility shall be used to first prepay all “Class C Notes” issued by Helios Issuer, LLC (“Helios Repayment”) and, if there are excess proceeds following the Helios Repayment, for general corporate purposes of the Borrower.

Cash Management:

• Borrower Deposit Account Control Agreement (“DACA”)

• With respect to the net proceeds of individual asset sales actually received by the Borrower, amounts below $5 million will be deposited into the MPA, and amounts equal to and greater than $5 million will be deposited into the WA whereby.

Borrower retaining at least 50.1% of the economic rights via an equity structure whereby SEC and the new investor are allocated cash-flows on a pro-rata basis and new investor is not allocated cash exceeding 50.0% of available cash (for the avoidance of doubt, a customary tax equity partnership shall be permitted by this clause (i) irrespective of the cash allocations under such partnership);
