GUARANTY

GUARANTY (this “Guaranty”) dated as of March 16, 2012 by Bloom Energy Corporation, a Delaware corporation (the “Guarantor”), in favor of Mehetia Inc., a Delaware corporation (the “Guaranteed Party”).

PRELIMINARY STATEMENTS

A. The Guarantor desires to have the Guaranteed Party enter into certain Transaction Documents (as defined below) with Clean Technologies II, LLC, a Delaware limited liability company (“Clean Technologies II”), which is a subsidiary of the Guarantor.

B. The Guaranteed Party is willing to enter into the Transaction Documents with Clean Technologies II only on the condition, among others, that Clean Technologies II’s payment obligations under such Transaction Documents are guaranteed by the Guarantor, on the terms set forth in this Guaranty.

NOW, THEREFORE, in consideration of the premises and in order to induce the Guaranteed Party to enter into the Transaction Documents, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Guarantor hereby agrees as follows:

1. Definitions.

1.1 Defined Terms. As used in this Guaranty, the capitalized terms defined in the preamble, preliminary statements and other sections of this Guaranty shall have the respective meanings specified therein; capitalized terms not defined in this Guaranty shall have the meanings given to such terms in the Equity Capital Contribution Agreement, dated as of March 16, 2012 (the “Contribution Agreement”), among the Guaranteed Party, Clean Technologies II, Diamond State Generation Holdings, LLC and Diamond State Generation Partners, LLC, and the following terms shall have the following meanings:

“Obligations” shall mean, without duplication, (i) the due and punctual payment of all amounts payable by Clean Technologies II pursuant to the Transaction Documents, including, without limitation, (A) any Investor Indemnified Costs as and when due in accordance with the Contribution Agreement or the Amended and Restated Limited Liability Company Agreement of Diamond State Generation Holdings, LLC to be entered into between the Guaranteed Party and Clean Technologies II (the “Company LLC Agreement”), as the case may be, (B) all Capital Contributions owed by Clean Technologies II, and (C) all amounts payable by Clean Technologies II as Recapture Damages as a result of a Class A Recapture Event, (ii) to the extent the Administrator is an Affiliate of the Guarantor, the due and punctual payment by such Affiliate of all amounts payable by such Affiliate as Administrator under the Administrative Services Agreement, and (iii) the payment of all other payment obligations of Clean Technologies II to the Guaranteed Party, whether direct or indirect, absolute or contingent, due or to become due, which may arise under or in connection with the Transaction Documents (including, without limitation, interest or other charges as would have accrued on any portion of the payment obligations but for the commencement of any bankruptcy or insolvency proceedings, it being the intention of the Parties that the Obligations that are guaranteed by the Guarantor pursuant to this Guaranty should be determined without regard to any rule of law or order that may relieve Clean Technologies II of any portion of such Obligations).

“Transaction Documents” shall mean (i) the Contribution Agreement, (ii) the Company LLC Agreement, and (iii) to the extent the Administrator thereunder is an Affiliate of the Guarantor, the Administrative Services Agreement.

1.2 Terms Generally. The definitions of terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be modified by the phrase “without limitation”. The word “will” shall be construed to have the same meaning and effect as the word “shall”. Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument of other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified in accordance with the provisions hereof and thereof; (b) any reference herein to any person shall be construed to include such person’s successors and permitted assigns; (c) the words “herein,” “hereof” and “hereunder,” and words of similar import, shall be construed to refer to this Guaranty in its entirety and not to any particular provision of this Guaranty; and (d) the words “asset” and “property” shall be construed to have the same meaning and effect and to refer to any and all tangible and intangible assets and properties. Article and section headings used herein are for convenience of reference only, are not part of this Guaranty and shall not affect the construction of, or be taken into consideration in interpreting, this Guaranty.

2. Guaranty.

2.1 Irrevocable Guaranty.

(a) The Guarantor hereby unconditionally and irrevocably guarantees to the Guaranteed Party and each of its successors, permitted indorsees, permitted transferees and permitted assigns that all monetary Obligations will be promptly paid in full, in Dollars, when due in accordance with the provisions of the Transaction Documents. If for any reason any sums stated in the Transaction Documents to be payable by Clean Technologies II, or any part thereof, shall not be paid promptly when due, then in each such instance upon written demand of payment made by the Guaranteed Party to the Guarantor, the Guarantor shall pay the same to or for the benefit of the Guaranteed Party and in accordance with the provisions of the Transaction Documents.

(b) Whether or not legal action is instituted, the Guarantor agrees to reimburse the Guaranteed Party, upon written demand, for all reasonable attorneys’ fees and disbursements and all other reasonable costs and expenses incurred by the Guaranteed Party in successfully enforcing its rights under this Guaranty. Notwithstanding the foregoing, the Guarantor shall have no obligation to pay any such costs or expenses if, in any action or proceeding brought by the Guaranteed Party giving rise to a demand for payment of such costs or expenses, it is finally adjudicated by a court of competent jurisdiction that the Guarantor is not liable to make any payment under Section 2.1(a) of this Guaranty.

2

Notwithstanding anything to the contrary in this Section 2.1, the Guarantor’s liability in respect of any of the Obligations shall not exceed the liability of Clean Technologies II with respect to such Obligations under the Transaction Documents; provided, however, that such cap on liability shall not apply to reasonable costs, expenses and fees (including reasonable legal fees and disbursements) in excess of such maximum liability incurred by the Guaranteed Party in connection with enforcing this Guaranty.

2.2 No Subrogation. The Guarantor will not exercise any rights that it may acquire by way of subrogation under this Guaranty, by any payment made hereunder or otherwise, until all of the Obligations shall have been indefeasibly paid in full. If any amount shall be paid to the Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held in trust for the benefit of the Guaranteed Party and shall forthwith be paid to the Guaranteed Party to be credited and applied to such Obligations, whether matured or unmatured, in accordance with the terms of the applicable Transaction Document. If (a) the Guarantor shall make payment to the Guaranteed Party of all or any part of the Obligations and (b) all of the Obligations shall be indefeasibly paid in full, the Guaranteed Party will, at the Guarantor’s request and expense, execute and deliver to the Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to the Guarantor of an interest in the Obligations resulting from such payment by the Guarantor.

2.3 No Effect on Guaranty. The obligations of the Guarantor under this Guaranty shall not be altered, limited, impaired or otherwise affected by:

(a) any rescission of any demand for payment of any of the Obligations or any failure by the Guaranteed Party to make any such demand on Clean Technologies II or any other guarantor or to collect any payments from Clean Technologies II or any other guarantor or any release of Clean Technologies II or any other guarantor;

(b) any renewal, extension, modification, amendment, acceleration, compromise, waiver, indulgence, rescission, discharge, surrender or release, in whole or in part, or any assignment or transfer, of any of the Transaction Documents or the Obligations or any other instrument or agreement evidencing, relating to, securing or guaranteeing any of the Obligations, or the liability of any party to any of the foregoing or for any part thereof;

(c) the validity, regularity or enforceability of any of the Obligations or of the Transaction Documents or any other instrument or agreement evidencing, relating to, securing or guaranteeing any of the Obligations at any time or from time to time held by the Guaranteed Party;

(d) any change, whether direct or indirect, in the Guarantor’s relationship to Clean Technologies II, including any such change by reason of any merger or consolidation or any sale, transfer, issuance, spin-off, distribution or other disposition of any stock, equity interest or other security of Clean Technologies II, the Guarantor or any other entity;

(e) any act or omission of the Guaranteed Party relating in any way to the Obligations or to Clean Technologies II, including any failure to bring an action against any party liable on the Obligations, or any party liable on any guaranty of the Obligations, or to apply any funds of any such party held by the Guaranteed Party;

3

(f) any proceeding, voluntary or involuntary, involving bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of Clean Technologies II or any other guarantor or any defense which Clean Technologies II or any other guarantor may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding; and

(g) any other act or omission that may or might in any manner or to any extent vary the risk of the Guarantor or that may or might otherwise operate as a discharge of the Guarantor as a matter of law or equity, other than (i) the indefeasible payment in full in Dollars of all the Obligations, and (ii) as set forth in the next sentence.

Notwithstanding the foregoing, the Guarantor shall be entitled to assert any and all defenses which Clean Technologies II may have to the payment of any of the Obligations, other than defenses based upon (1) lack of authority, capacity, legal right or power of Clean Technologies II to enter into and/or perform its obligations under the Transaction Documents or (2) any insolvency, bankruptcy, reorganization, arrangement, composition, liquidation, dissolution or similar proceeding with respect to Clean Technologies II.

2.4 Continuing Guaranty; Termination. This Guaranty shall be construed as a continuing, absolute and unconditional guaranty of payment when due, and not of collection only, and the obligations of the Guarantor hereunder shall not be conditioned or contingent upon the pursuit by the Guaranteed Party at any time of any right or remedy against Clean Technologies II or against any other person which may be or become liable in respect of all or any part of the Obligations. This Guaranty shall remain in full force and effect until the Obligations shall have been satisfied by indefeasible payment in full, in Dollars, notwithstanding that from time to time during the term of the Transaction Documents, Clean Technologies II may be free from any Obligations.

2.5 Reinstatement of Guaranty. This Guaranty shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is avoided, rescinded or must otherwise be restored or returned by the Guaranteed Party to Clean Technologies II or its representative or to any other guarantor for any reason including as a result of any insolvency, bankruptcy or reorganization proceeding with respect to Clean Technologies II or the Guarantor, all as though such payment had not been made.

2.6 Financial Statements. To the extent not publicly available, the Guarantor shall deliver or cause to be delivered to the Guaranteed Party:

(a) As and when available, and in any event within sixty (60) calendar days after the end of each fiscal quarter of any fiscal year of the Guarantor, complete unaudited financial statements of the Guarantor for such fiscal quarter, including the balance sheet of the Guarantor as of the end of such quarter, profit and loss statements for the Guarantor for such quarter, and a statement of cash flows for Guarantor for such quarter, each of which shall be prepared in accordance with GAAP, subject to normal recurring year-end audit adjustments and the absence of footnotes; and

4

(b) As and when available and in any event by the following April 30 after the end of the fiscal year of the Guarantor, consolidated financial statements with respect to such fiscal year for the Guarantor that are audited and certified by an Accounting Firm, including the balance sheet showing the Guarantor’s financial position as of the end of such fiscal year, profit and loss statements for the Guarantor for such fiscal year, a statement of cash flows for the Guarantor for such fiscal year and related footnotes, prepared in accordance with GAAP.

2.7 Waivers.

(a) Without limiting the generality of any other waiver or other provision set forth in this Guaranty, Guarantor hereby waives all benefits and defenses that are or may become available to Guarantor by reason of California Civil Code Sections 2787 to 2855, inclusive, Section 2899 or Section 3433. Any references to certain sections of the California Civil Code or the California Code of Civil Procedure are included in this Guaranty solely out of an abundance of caution and shall not be construed to mean that any of the referenced provisions of California law are in any way applicable to this Guaranty.

(b) Without limiting the generality of any other waiver or other provision set forth in this Guaranty, Guarantor waives all rights and defenses that Guarantor may have if all or part of Guarantor’s obligations are secured by real property. This means, among other things:

(i) Guaranteed Party may collect from Guarantor without first foreclosing on any real or personal property collateral pledged by Guarantor, Clean Technologies II or any other guarantor.

(ii) If Guaranteed Party forecloses on any real property collateral pledged by Guarantor, Clean Technologies II or any other guarantor:

(A) The amount of Guarantor’s obligations or any obligations of Guarantor in respect thereof may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price.

(B) Guaranteed Party may collect from Guarantor even if Guaranteed Party, by foreclosing on the real property collateral, has destroyed any right Guarantor may have to collect from Clean Technologies or any other guarantor.

(c) This is an unconditional and irrevocable waiver of any rights and defenses Guarantor may have if all or part of Guarantor’s obligations are secured by real property. These rights and defenses include, but are not limited to, any rights or defenses based upon Section 580a, 580b, 580d, or 726 of the California Code of Civil Procedure.

(d) Without limiting the generality of any other waiver or other provision set forth in this Guaranty, Guarantor waives all rights and defenses arising out of an election of remedies by Guaranteed Party, even though that election of remedies, such as a nonjudicial foreclosure with respect to security for Guarantor’s obligations, has destroyed Guarantor’s rights of subrogation and reimbursement against Guaranteed Party by the operation of Section 580d of the California Code of Civil Procedure or otherwise, including any other statutory or decisional law of any applicable jurisdiction.
