In connection with such exchange, (A) a corresponding number of shares of Class B or Class B1 Common Stock, as applicable, held by the exchanging Global LLC Unitholder must be surrendered to Global LLC for delivery of such shares by Global LLC to the Corporation for cancellation, (B) the Corporation will issue and

3

contribute a corresponding number of shares of Class A Common Stock to Global LLC for delivery of such shares by Global LLC to the exchanging Global LLC Unitholder, (C) Global LLC will issue a corresponding number of additional Class A Units to the Corporation, (D) Global LLC will cancel the surrendered Global LLC Units and the Corporation will cancel the corresponding shares of Class B or Class B1 Common Stock, as applicable, and (E) Global LLC will deliver the shares of Class A Common Stock it receives from the Corporation to the exchanging Global LLC Unitholder.

(b) A Global LLC Unitholder shall exercise its right to Exchange Global LLC Units as set forth in (a) above by delivering to the Corporation and to Global LLC a written election of exchange in respect of the Global LLC Units to be Exchanged substantially in the form of Exhibit A hereto (an “Election of Exchange”), duly executed by such holder or such holder’s duly authorized representative, in each case delivered during normal business hours at the principal executive offices of the Corporation and of Global LLC. An Election of Exchange may specify that the Exchange is to be contingent (including as to timing) upon the occurrence of any transaction or event, including the consummation of a purchase by another Person (whether in a tender or exchange offer, an underwritten offering or otherwise) of shares of Class A Common Stock or any merger, consolidation or other business combination. Subject to (i) Section 2.4(b) of this Agreement, (ii) the payment by the applicable Global LLC Unitholder of any amount required to be paid under (c) and (iii) the surrender to Global LLC of the unit certificates, if any, and duly executed unit powers associated with the Global LLC Units subject to the Exchange, the Exchange shall be deemed to have been effected on (A) the Business Day immediately following receipt of the applicable Election of Exchange or (B) such later date specified in or pursuant to the applicable Election of Exchange (such date specified in clause (A) or (B), as applicable, the “Exchange Date”), and as promptly as practicable following the applicable Exchange Date, the Corporation shall deliver or cause to be delivered at the offices of the then-acting registrar and transfer agent of the Class A Common Stock or, if there is no then-acting registrar and transfer agent of the Class A Common Stock, at the principal executive offices of Global LLC, the number of shares of Class A Common Stock deliverable upon such Exchange. Global LLC shall then deliver or cause to be delivered such shares of Class A Common Stock to the relevant exchanging Global LLC Unitholder (or its designee). Notwithstanding anything herein to the contrary, any exchanging Global LLC Unitholder may withdraw or amend an Election of Exchange, in whole or in part, prior to the effectiveness of the Exchange, at any time prior to 5:00 p.m., New York City time, on the second Business Day immediately preceding the Exchange Date (or any such later time as may be required by applicable law) by delivery of a written notice of withdrawal to the Corporation and to Global LLC, specifying (1) the number of Global LLC Units being withdrawn, (2) the number of Global LLC Units, if any, as to which the Election of Exchange remains in effect and (3) if such exchanging Global LLC Unitholder so determines, a new Exchange Date or any other new or revised information permitted in an Election of Exchange. On the Exchange Date, all rights of the exchanging Global LLC Unitholder as a holder of such Global LLC Units shall cease and such Global LLC Units shall be cancelled, and Global LLC shall issue to the Corporation a number of Class A Units equal to the number of such Global LLC Units cancelled. On the Exchange Date, the exchanging Global LLC Unitholder shall be treated for all purposes as having become the record holder of the

4

shares of Class A Common Stock to be exchanged for the cancelled Global LLC Units. In connection with the Exchange, the Corporation shall automatically cancel shares of Class B or B1 Common Stock, as applicable, held by the exchanging Global LLC Unitholder, immediately after such shares of common stock are transferred to Global LLC, in an amount corresponding to the number of Global LLC Units being exchanged in accordance with this Section 2.1. The Corporation shall take such actions as may be required to ensure the performance by Global LLC of its obligations under this (b) and the foregoing (a).

(c) Global LLC, the Corporation and the exchanging Global LLC Unitholder shall bear their own expenses in connection with the consummation of any Exchange, whether or not any such Exchange is ultimately consummated, except that Global LLC shall bear any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, any Exchange; provided, however, that if any shares of Class A Common Stock are to be delivered in a name other than that of the Global LLC Unitholder that requested the Exchange, then such Global LLC Unitholder and/or the person in whose name such shares are to be delivered shall pay to Global LLC the amount of any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Exchange or shall establish to the reasonable satisfaction of Global LLC that such tax has been paid or is not payable.

(d) Each of the Corporation and Global LLC covenants and agrees that it will not take any action that would pose a material risk that Global LLC could be treated as a “publicly traded partnership” for U.S. federal income tax purposes. Notwithstanding anything to the contrary herein, no Exchange shall be permitted (and, if attempted, shall be void ab initio) if, in the opinion of legal counsel or a qualified tax advisor to Global LLC, such an Exchange would present a material risk that such Exchange would cause Global LLC to cease to be classified as a partnership or to be classified as a “publicly traded partnership” within the meaning of Section 7704(b) of the Code for U.S. federal income tax purposes.

(e) For the avoidance of doubt, and notwithstanding anything to the contrary herein, a Global LLC Unitholder shall not be entitled to Exchange Global LLC Units to the extent the Corporation or Global LLC reasonably determines in good faith that such Exchange (i) would be prohibited by applicable law or regulation, including Applicable Securities Laws, or (ii) would not be permitted under any other agreement between such Global LLC Unitholder and the Corporation or its subsidiaries (including the Global LLC Operating Agreement).

Section 2.2 Adjustment. The Exchange Rate shall be adjusted accordingly if there is: (a) any subdivision (by any unit split, unit distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization or otherwise) of the Class A Units, Class B Units or Class B1 Units that is not accompanied by an identical subdivision or combination of the Class A Common Stock; (b) any subdivision (by any stock split, stock dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock split, reclassification, reorganization, recapitalization or otherwise) of the Class A Common

5

Stock that is not accompanied by an identical subdivision or combination of the Class A Units, Class B Units or Class B1 Units; (c) (1) any issuance of shares of (x) Class A Common Stock by the Corporation or (y) Class A Units to the Corporation that is not accompanied by (2) the issuance of an identical number of (x) Class A Units to the Corporation (in the case of clause (c)(1)(x)) or (y) shares of Class A Common Stock (in the case of clause (c)(1)(y)), as applicable; or (d) (1) any issuance of (x) shares of Class B or Class B1 Common Stock by the Corporation or (y) Class B or Class B1 Units to SunEdison or its Permitted Transferees that is not accompanied by (2) the issuance of an identical number of (x) Class B or Class B1 Units to SunEdison or to any Permitted Transferee of SunEdison (in the case of clause (d)(1)(x)) or (y) shares of Class B or Class B1 Common Stock to SunEdison or its Permitted Transferees (in the case of clause (d)(1)(y)). If there is (i) any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock is converted or changed into another security, securities or other property or (ii) and any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction, then upon any subsequent Exchange, an exchanging Global LLC Unitholder shall be entitled to receive the amount of such security, securities or other property that such exchanging Global LLC Unitholder would have received if such Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, taking into account any adjustment as a result of any such subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction. For the avoidance of doubt, if there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock is converted or changed into another security, securities or other property, this Section 2.2 shall continue to be applicable, mutatis mutandis, with respect to such security or other property. This Agreement shall apply to the Class A Units, Class B Units or Class B1 Units held by the Corporation, SunEdison and SunEdison’s Permitted Transferees as of the date hereof, as well as any Class A Units, Class B Units and Class B1 Units hereafter acquired by the Corporation, SunEdison or any of SunEdison’s Permitted Transferees. This Agreement shall apply to, mutatis mutandis, and all references to “Class A Units,” “Class B Units” or “Class B1 Units” shall be deemed to include, any security, securities or other property of Global LLC which may be issued in respect of, in exchange for or in substitution of Class A Units, Class B Units or Class B1 Units, as applicable, by reason of any distribution or dividend, split, reverse split, combination, reclassification, reorganization, recapitalization, merger, exchange (other than an Exchange) or other transaction.

Section 2.3 Class A Common Stock to be Issued.

(a) If any Exchange in accordance with this Agreement is to be effected in a manner that would require registration under Applicable Securities Laws and such required registration has not become effective or otherwise is unavailable, upon the request and with the reasonable cooperation of the Global LLC Unitholder requesting the Exchange, the Corporation shall use its commercially reasonable efforts to promptly facilitate such Exchange pursuant to any reasonably available exemption from such

6

registration requirements. The Corporation shall use its commercially reasonable efforts to list the Class A Common Stock required to be delivered upon Exchange prior to such delivery upon each national securities exchange or inter-dealer quotation system upon which the outstanding Class A Common Stock may be listed or traded at the time of such delivery.

(b) The Corporation shall at all times reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the purpose of issuance upon an Exchange, such number of shares of Class A Common Stock as shall be deliverable upon any such Exchange; provided that nothing contained herein shall be construed to preclude Global LLC from satisfying its obligations in respect of the Exchange of Global LLC Units by delivery of Class A Common Stock which is held in the treasury of the Corporation, in a manner consistent with the requirements of Treasury Regulations Section 1.1032-3(c) so as to allow Global LLC to make such exchange without recognizing any gain or loss on the transaction for federal income tax purposes.

(c) Prior to the effective date of this Agreement, the Corporation and Global LLC will take all such steps as may be required to cause to qualify for exemption under Rule 16b-3(d) or (e), as applicable, under the Exchange Act, and be exempt for purposes of Section 16(b) under the Exchange Act, any acquisitions or dispositions of equity securities of the Corporation (including derivative securities with respect thereto) and any securities which may be deemed to be equity securities or derivative securities of the Corporation for such purposes that result from the transactions contemplated by this Agreement, by each Global LLC Unitholder who may reasonably be expected to be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Corporation upon the registration of any class of equity security of the Corporation pursuant to Section 12 of the Exchange Act (with the authorizing resolutions specifying the name of each such Global LLC Unitholder whose acquisition or disposition of securities is to be exempted and the number of securities that may be acquired and disposed of by each such person pursuant to this Agreement).

(d) If any Takeover Law (as defined below) or other similar law or regulation becomes or is deemed to become applicable to this Agreement or any of the transactions contemplated hereby, the Corporation or Global LLC shall use their commercially reasonable efforts to render such law or regulation inapplicable to all of the foregoing.

(e) Each of the Corporation and Global LLC covenants that all Class A Common Stock issued upon an Exchange will, upon issuance, be validly issued, fully paid and non-assessable, will pass to the applicable exchanging Global LLC Unitholder free and clear of any liens, security interests and other encumbrances other than any such liens, security interests or other encumbrances imposed by such exchanging Global LLC Unitholder and will not be subject to any preemptive right of stockholders of the Corporation or to any right of first refusal or other right in favor of any person or entity.

(f) No Exchange shall impair the right of the exchanging Global LLC Unitholder to receive any distributions payable on the Global LLC Units so exchanged in respect of a record date that occurs prior to the Exchange Date for such Exchange. For

7

the avoidance of doubt, no exchanging Global LLC Unitholder shall be entitled to receive, in respect of a single record date, distributions or dividends both on Global LLC Units exchanged by such holder and on Class A Common Stock received by such holder in such Exchange.

Each Global LLC Unitholder acknowledges and agrees that the shares of Class A Common Stock to be issued upon the occurrence of an Exchange in a transaction not registered under the Securities Act will constitute “restricted securities” as defined by Rule 144 promulgated under the Securities Act, and may not be sold or transferred in the absence of an effective registration statement under the Securities Act and registration or qualification under other Applicable Securities Laws or an exemption from such registration or qualification and certificates (or account entries in the case of book-entry securities) evidencing shares of Class A Common Stock issued upon an Exchange may bear an appropriate legend.

Section 2.4 Withholding; Certification of Non-Foreign Status.

(a) If the Corporation or Global LLC shall be required to withhold any amounts by reason of any Federal, State, local or foreign tax rules or regulations in respect of any Exchange, the Corporation or Global LLC, as the case may be, shall be entitled to take such action as it deems appropriate in order to ensure compliance with such withholding requirements, including at its option withholding shares of Class A Common Stock with a fair market value equal to the minimum amount of any taxes which the Corporation or Global LLC, as the case may be, may be required to withhold with respect to such Exchange. To the extent that amounts (or property) are so withheld and paid over to the appropriate taxing authority, such withheld amounts (or property) shall be treated for all purposes of this Agreement as having been paid (or delivered) to the appropriate Global LLC Unitholder.

(b) Notwithstanding anything to the contrary herein, each of Global LLC and the Corporation may, at its own discretion, require as a condition to the effectiveness of an Exchange that an exchanging Global LLC Unitholder deliver to Global LLC or the Corporation, as the case may be, a certification of non-foreign status in accordance with Treasury Regulation Section 1.1445-2(b). In the event Global LLC or the Corporation has required delivery of such certification but an exchanging Global LLC Unitholder is unable to do so, Global LLC shall nevertheless deliver or cause to be delivered to the exchanging Global LLC Unitholder the Class A Common Stock in accordance with Section 2.1 of this Agreement, but subject to potential withholding as provided in (a).

Section 4.8 Waiver. No failure by any party to insist upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute waiver of any such breach of any other covenant, duty, agreement or condition.

Section 4.11 Tax Treatment. This Agreement shall be treated as part of the partnership agreement of Global LLC as described in Section 761(c) of the Code and Sections 1.704-1(b)(2)(ii)(h) and 1.761-1(c) of the Treasury Regulations promulgated thereunder. Each party hereto agrees to report each Exchange for U.S. federal income tax purposes as a taxable sale or exchange of Class B or Class B1 Units by the applicable Global LLC Unitholder in exchange for Class A Common Stock (in conjunction with the cancellation of Class B or Class B1 Common Stock, as applicable) and no party shall take a contrary position on any U.S. federal, state or local income tax return: (i) except as otherwise required by a “determination” as defined in Section 1313 of the Code, or (ii) unless such party provides a written opinion by a nationally recognized accounting or law firm, which opinion is reasonably satisfactory to both SunEdison and Global LLC, that such Exchange should not be treated as a taxable sale or exchange for federal income tax purposes.

Section 4.12 Specific Performance. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to specific performance of the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity.

Section 4.13 Independent Nature of Global LLC Unitholders’ Rights and Obligations. The obligations of each Global LLC Unitholder hereunder are several and not joint with the obligations of any other Global LLC Unitholder, and no Global LLC Unitholder shall be responsible in any way for the performance of the obligations of any other Global LLC Unitholder hereunder. The decision of each Global LLC Unitholder to enter into to this Agreement has been made by such Global LLC Unitholder independently of any other Global LLC Unitholder. Nothing contained herein, and no action taken by any Global LLC Unitholder pursuant hereto, shall be deemed to constitute an action of the Global LLC Unitholders as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Global LLC Unitholders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby and the Corporation acknowledges that the Global LLC Unitholders are not acting in concert or as a group, and the Corporation will not assert any such claim, with respect to such obligations or the transactions contemplated hereby.

Section 4.14 Applicable Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Delaware.
