CAPITAL CONTRIBUTIONS

Each Equity Contributor, severally in accordance with Section 2.7, undertakes to provide directly or indirectly to the Borrower the required amounts of Base Equity and Overrun Equity, on and subject to the terms and conditions of this Agreement.

2.1 Base Equity Commitments

2.1.1 Amount of Base Equity Commitment

Each Equity Contributor irrevocably commits to provide to the Borrower, directly or indirectly, in accordance with Section 2.3.1, its share of the Aggregate Base Equity Commitment Balance in an amount determined by the following formula:

(A * B) – C

where

A = such Equity Contributor’s Base Equity Percentage,

B = the Aggregate Base Equity Amount, and

C = the aggregate amount of such Equity Contributor’s prior Base Equity Contributions (excluding the amount of any Approved Pre-Closing Equity Credit).

No Equity Contributor’s commitment under this Section 2.1.1 (its “Individual Base Equity Commitment Balance”) can be less than zero.

6

2.1.2 Form of Base Equity Commitments

(a) Each Equity Contributor shall secure its Base Equity Commitment from the Financial Closing Date through the date described in Section 2.2.4 by providing Base Equity Commitment Balance Security in an amount not less than the amount of such Equity Contributor’s Individual Base Equity Commitment Balance.

(b) If at any time an Equity Contributor breaches Section 2.1.2(a), such Equity Contributor shall cure such deficiency within 10 days after receipt of a written demand from the Collateral Agent or the Loan Servicer. If at any time the amount of an Equity Contributor’s Base Equity Commitment Balance Security is greater than such Equity Contributor’s Individual Base Equity Commitment Balance, such Equity Contributor’s Base Equity Commitment Balance Security may be accordingly reduced.

2.2 Overrun Equity Commitment

2.2.1 Unlimited Sponsor Overrun Equity Commitment

The Sponsor irrevocably commits to provide to the Borrower, in accordance with Section 2.3.2, Overrun Equity in the aggregate amount equal to 100% of all Overrun Project Costs incurred at any time prior to the Operational Completion Date; provided, however, that all Overrun Project Costs shall be funded to the extent available (i) first, from Available Owner’s Contingency (as defined in Section 2.2.3(c) below), (ii) second, from Funded Overrun Equity, and (iii) thereafter, by additional funds provided by the Sponsor.

2.2.2 Amount of Funded Overrun Equity Commitment

Without limiting the Sponsor’s obligations under Section 2.2.1, each Equity Contributor irrevocably commits to provide to the Borrower, directly or indirectly, in accordance with Section 2.3.2, its share of the Funded Overrun Equity Balance in an amount determined by the following formula (“Funded Overrun Equity”):

(A * B) – C

where

A = such Equity Contributor’s Funded Overrun Equity Percentage,

B = the Funded Overrun Equity Amount,

C = the aggregate amount of such Equity Contributor’s prior Funded Overrun Equity Contributions.

No Equity Contributor’s commitment under this Section 2.2.2 (its “Individual Funded Overrun Equity Commitment Balance”) can be less than zero.

2.2.3 Form of Funded Overrun Equity Commitment

(a) Each Equity Contributor shall secure its share of the Funded Overrun Equity Commitment by providing Funded Overrun Equity Commitment Balance Security in an amount not less than the amount of such Equity Contributor’s Individual Funded Overrun Equity Commitment Balance. With respect to any Funded Overrun Equity Commitment Balance Security provided by an Equity Contributor in the form of Cash Collateral,

7

(i) such Cash Collateral shall be deposited into a separate Funded Overrun Equity Account established by the Collateral Agent, and (ii) such Equity Contributor shall enter into such agreements and instruments as are necessary to create and perfect a first-priority security interest under applicable law in such Cash Collateral, and shall provide customary legal opinions with respect to such creation and perfection.

(b) Each Equity Contributor’s share of the Funded Overrun Equity Balance Security may, in accordance with the following two paragraphs, be established over time as such Equity Contributor contributes its Funded Overrun Equity Percentage of Funded Overrun Equity Balance Security, provided, however, that such establishment of each Equity Contributor’s share of the Funded Overrun Equity Balance Security shall be made in accordance with Sections 2.2.3(c) and (d) below.

(c) Each month the Loan Servicer shall cause the Lender’s Engineer to calculate and provide to the Loan Servicer in the Lender’s Engineer Construction Progress Report the amount of Owner’s Contingency that has not been allocated to, or used to fund, identified Project Costs and remains available for the allocation to, and payment of, future Project Costs, the amount of any Funded Overrun Equity Contributions previously made in accordance with this Section 2.2.3 that have not been allocated to, or used to fund, Project Costs and remain available for the allocation to, and payment of, future Project Costs and the amount of the Funded Overrun Equity Commitment Balance Security (“Available Owner’s Contingency”), together with a calculation in reasonable detail of the basis for such calculation. The Loan Servicer shall review and approve such calculation of Available Owner’s Contingency and provide a copy thereof to the Borrower and each Equity Contributor.

(d) If at any time the amount of Available Owner’s Contingency has been reduced to less than 2.00% of Base Project Costs, then not later than 10 days after receipt of such notice (the “Overrun Equity Contribution Date”), the Equity Contributors shall increase the Funded Overrun Equity Commitment Balance Security in an aggregate amount equal to the lesser of (i) the amount required to increase the Available Owner’s Contingency to 3.00% of Base Project Costs and (ii) the then-remaining Funded Overrun Equity Balance.

(e) If at any time an Equity Contributor breaches Section 2.2.3, such Equity Contributor shall cure such deficiency within 10 days after written demand from the Collateral Agent or the Loan Servicer.

(f) If at any time the amount of an Equity Contributor’s Funded Overrun Equity Commitment Balance Security is greater than the amount of such Equity Contributor’s Individual Funded Overrun Equity Commitment Balance, such Equity Contributor’s Funded Overrun Equity Commitment Balance Security may be accordingly reduced by written notice to the Loan Servicer and the Collateral Agent.

2.2.4 Release of Amounts in Equity Funding Account

On the date that (x) Operational Completion has occurred and (y) the Borrower has established and funded a reserve in an amount determined by the Borrower and approved by the Lender’s Engineer to be sufficient to pay all out-of-pocket costs (net of any warranty payments) that the

8

Borrower is reasonably likely to incur with respect to any punch-list or other items required to achieve Final Construction Completion (the “Equity Commitment Security Release Date”), (i) DOE shall promptly take all action required to release all Base Equity Commitment Balance Security and Funded Overrun Equity Commitment Balance Security (excluding such reserve), and (ii) DOE shall instruct the Collateral Agent in accordance with the Common Agreement to pay to each applicable Equity Contributor any remaining balance in the Equity Funding Account contributed by it and not otherwise used as Base Equity or Funded Overrun Equity to fund Project Costs. Any excess funds returned to the Equity Contributors from the Equity Funding Account shall be returned in the proportions directed by the Equity Contributors.

2.3 Procedures for Equity Contributions

2.3.1 Base Equity Contributions to Borrower

Not later than the date on which the applicable Base Equity Contribution is required to be made pursuant to Section 2.4.2 of the Common Agreement (the “Base Equity Contribution Date”), each Equity Contributor shall cause its share of each Base Equity Contribution, in an amount equal to the product of (x) the Base Equity Percentage for such Equity Contributor, and (y) the aggregate Base Equity Contributions required on the applicable Base Equity Contribution Date, to be made to the Borrower, provided that no Equity Contributor shall be obligated to make Base Equity Contributions in excess of its Individual Base Equity Commitment Balance. Base Equity Contributions may be made by:

(a) instructing the Collateral Agent in the applicable Master Advance Notice to draw on a Reserve Letter of Credit provided by such Equity Contributor in accordance with Section 2.6 in a specified amount for deposit by the Collateral Agent into the Disbursement Account;

(b) instructing the Collateral Agent to draw funding from Cash Collateral provided by such Equity Contributor in accordance with Section 2.6 in the applicable Master Advance Notice in a specified amount for deposit by the Collateral Agent into the Disbursement Account; or

(c) depositing cash into (i) the Disbursement Account or (ii) the Equity Funding Account.

To the extent an Equity Contributor makes a Base Equity Contribution, such Equity Contributor’s Individual Base Equity Commitment Balance shall be reduced accordingly.

Each Equity Contributor’s obligations under this Section 2.3.1 shall expire, and no Equity Investor will have any further obligation to make any Base Equity Contributions, from and after the PPA Required Performance Date.

2.3.2 Overrun Equity Contributions to Borrower

(a) Without limiting the Sponsor’s obligations under Section 2.2.1 or Article VII, and notwithstanding the release of Funded Overrun Equity Commitment Balance Security pursuant to Section 2.2.4, not later than the applicable Overrun Equity Contribution Date, each Equity Contributor shall cause its share of each Overrun Equity Contribution, in an amount equal to the product of (x) the Funded Overrun Equity Percentage for such Equity

9

Contributor, and (y) the aggregate Overrun Equity Contributions required on the applicable Overrun Equity Contribution Date, to be made to the Borrower, provided that no Equity Contributor shall be obligated to make Overrun Equity Contributions in excess of its Individual Funded Overrun Equity Commitment Balance. To the extent an Equity Contributor is excused from making an Overrun Equity Contribution because it has reduced its Individual Funded Overrun Equity Commitment Balance to zero, the Sponsor shall make the Overrun Equity Contribution that the applicable Equity Contributor would have made but for the cap in Section 2.2.2.

(b) Prior to the Equity Commitment Security Release Date, Overrun Equity Contributions may be made by:

(i) instructing the Collateral Agent in the applicable Master Advance Notice to draw on a Reserve Letter of Credit provided by such Equity Contributor in accordance with Section 2.6 in a specified amount for deposit by the Collateral Agent into the Disbursement Account; or

(ii) instructing the Collateral Agent to draw funding from Cash Collateral provided by such Equity Contributor in accordance with Section 2.6 in the applicable Master Advance Notice in a specified amount for deposit by the Collateral Agent into the Disbursement Account; or

(iii) depositing cash into the Disbursement Account in accordance with the Common Agreement.

(c) From and after the Equity Commitment Security Release Date, Overrun Equity Contributions may be made by depositing cash into the Disbursement Account in accordance with the Common Agreement.

(d) To the extent an Equity Contributor makes an Overrun Equity Contribution, such Equity Contributor’s Individual Funded Overrun Equity Commitment Balance shall be reduced accordingly.

(e) Each Equity Contributor’s obligations under this Section 2.3.2 shall expire, and no Equity Investor will have any further obligation to make any Overrun Equity Contributions, from and after the PPA Required Performance Date.

(f) For the avoidance of doubt, the proceeds of the Funded Overrun Equity Commitment may not be used to pay amounts outstanding under the FFB Credit Facility. Following the occurrence of an Event of Default, Funded Overrun Equity may only be drawn down (i) from time to time as required, to pay costs the Loan Servicer determines to be necessary to continue the development, design and construction of the Project, and (ii) to the extent of the Funded Overrun Equity Commitment Balance Security that is in place as of the date of the Event of Default.

10

2.3.3 Equity Contribution Shortfalls

(a) If any Equity Contributor does not timely make the full amount of any Equity Contribution it is required to make, and such failure continues for two (2) Business Days after receipt of written notice from the Loan Servicer, then the Loan Servicer, by instruction to the Collateral Agent, may elect to fund the shortfall by drawing on any of the sources available provided by the relevant Equity Contributor as specified in Sections 2.1.2 or 2.2.3. If the required funds are made available to the Collateral Agent consistent with the terms of the applicable security or guaranty documents, the applicable Base Equity Contribution shall be deemed timely made.

(b) If as of any Base Equity Contribution Date or Overrun Equity Contribution Date, (i) an Equity Contributor has made Equity Contributions to the Equity Funding Account in excess of the amounts required from such Equity Contributor under Section 2.3.1 or Section 2.3.2 (as applicable) and (ii) another Equity Contributor has failed to make all of its required Equity Contribution under Section 2.3.1 or Section 2.3.2 (as applicable), the Credit Parties shall not transfer the excess Equity Contributions of the overfunding Equity Contributor from the Equity Funding Account to make up for the shortfall of the underfunding Equity Contributor, unless and until an Equity Acceleration Date occurs.

2.3.4 Accelerated Equity Contributions

(a) Promptly upon delivery by the Loan Servicer to the Equity Contributors at any time prior to the Operational Completion Date of a notice in the form of Exhibit A hereto demanding an Accelerated Equity Contribution pursuant to Section 8.2(f) of the Common Agreement, without further notice of default, presentment or demand for payment, protest or notice of non-payment or dishonor, or other notices or demands of any kind, all such notices and demands being waived, and without limiting the Sponsor’s obligations under Section 2.2.1, but subject to each Equity Contributor’s maximum Individual Base Equity Commitment Balance (as the same may have been reduced on account of prior Base Equity Contributions), each Equity Contributor shall, on the date specified therefor, deposit into the Equity Funding Account an amount of cash equal to the excess, if any, of (x) its Base Equity Percentage of such Aggregate Base Equity Amount over (y) the amount of Base Equity Contributions made by such Equity Contributor prior to the date of the Accelerated Equity Contribution.

(b) The right of the Loan Servicer to demand an Accelerated Equity Contribution (including from BrightSource Ivanpah pursuant to Section 7.3.3) shall not limit any other right or remedy of DOE, the Loan Servicer or any other Credit Party under any Loan Document or the Governmental Rules, nor shall any Credit Party be obligated to pursue any right or remedy or proceed against, or elect or exhaust any remedies with respect to, any other Person or any Collateral Security. Each Equity Contributor hereby irrevocably waives any defense of a guarantor or surety to which such Equity Contributor might be entitled under any Governmental Rules with respect to any Accelerated Equity Contribution.

2.4 Proceeds of Equity Contributions

(a) Each Equity Contribution required to be made in cash shall be made in immediately available funds in Dollars.

11

(b) Proceeds of any Equity Contribution (other than in connection with an Accelerated Equity Contribution) shall be made available to the Borrower in accordance with Section 2.4 and Article 9 of the Common Agreement.

(c) Proceeds of any Accelerated Equity Contribution shall be applied in accordance with Section 8.2 of the Common Agreement.

2.5 Grant of Security Interest

As security for the payment and performance of its obligations under this Agreement and the other Secured Obligations, each Equity Contributor hereby grants to the Collateral Agent, for itself and on behalf of and for the ratable benefit of the other Secured Parties, a first priority perfected security interest in the Equity Funding Account and all proceeds thereof (the “Collateral”). Each Equity Contributor agrees that this Agreement shall create a continuing security interest in the Collateral which shall remain in effect until the termination of the FFB Credit Facility Commitment and payment and performance in full of all Secured Obligations (other than inchoate indemnity obligations).

2.6 Drawing under Reserve Letters of Credit

Any Reserve Letter of Credit shall provide for drawing upon presentation of a certificate of the Collateral Agent to the effect that (i) an amount owing under Article II by the Equity Contributor providing such Reserve Letter of Credit (or owing under Article VII with respect to any Reserve Letter of Credit provided by BrightSource Ivanpah thereunder) has not been paid by such Equity Contributor on the date when due, (ii) the issuer thereof has ceased to have the credit quality described in the definition of Reserve Letter of Credit, or (iii) 45 days prior to the date of expiration thereof such Reserve Letter of Credit has not been renewed or replaced by (A) another Reserve Letter of Credit, (B) Cash Collateral, (C) an Equity Contribution Guaranty from a Creditworthy Party, or (D) a cash contribution to the Equity Funding Account.

2.7 Several Obligations

The liability of each Equity Contributor under this Agreement is limited as set out in this Agreement and is several (and not joint). Without limiting the Sponsor’s obligations under Section 2.2.1, the obligations of each Equity Contributor under this Agreement shall be in proportion to such Equity Contributor’s Base Equity Percentage (for matters concerning Base Equity) or Funded Overrun Equity Percentage (for matters concerning Funded Overrun Equity). No Equity Contributor is liable for the obligations of any other Equity Contributor under this Agreement. Failure of an Equity Contributor to carry out its obligations under this Agreement shall not relieve any other Equity Contributor of its obligations under this Agreement. The Parties acknowledge that Equity Contributions may be funded through equity funding to intermediate holding companies between the Borrower and the Equity Contributors and any funding through such an intermediary shall constitute Equity Contributions of the applicable Equity Contributor, so long as the funds representing such Equity Contributions are deposited into the applicable Project Account. Payments made by any other Person of an Equity Contribution an Equity Contributor has failed to make shall be deemed for all purposes of this Agreement to have been made by such Equity Contributor and to have cured any failure by such Equity Contributor to make such Equity Contribution.

(vi) notwithstanding the foregoing, (A) the Common Agreement and the DOE Conditional Commitment shall remain in full force and effect and be binding on each party thereto, but DOE shall have no further obligations under Article 4 of the Common Agreement, and (B) no FFB Credit Facility Fees or other amounts previously paid pursuant to the Common Agreement or the DOE Conditional Commitment shall be refunded.

ARTICLE VI

INDEMNITY FOR CASH GRANT RECAPTURE, ITC

6.1 Transfer of Equity Interests; No Disqualified Persons.

(a) At all times during the Recapture Period, each Equity Contributor agrees that it shall not:

(i) become, or with respect to any Person that directly or indirectly owns Equity Interests in such Equity Contributor (with respect to each Equity Contributor, its “Equity Contributor Affiliated Parties”), suffer, permit or consent to such Equity Contributor Affiliated Party becoming, a Disqualified Person, including by changing its tax status; or

(ii) cause or make or, with respect to any sale, assignment, issuance or transfer by any Equity Contributor Affiliated Party, suffer, permit or consent to, any sale, assignment, issuance or transfer (A) of (x) any direct, indirect or beneficial Equity Interests of the Borrower to any Disqualified Person, or (y) any Project assets to a Disqualified Person, or (B) that would cause the property to cease to qualify as a specified energy property within five years from the date the Project is “placed in service” (for the purposes of Section 48 of the Internal Revenue Code);

provided, however, that this Section 6.1(a) shall not (A) apply to any sale, assignment or transfer of any direct or indirect ownership interest or other interest in the Borrower or in any Project assets that would cause the Borrower to be a Disqualified Person if such sale, assignment or transfer results from the acts or omission of, at the direction of, or with the permission of, any Credit Party or (B) cause, in any way, any Equity Contributor to be responsible for the actions or inactions of any Equity Contributor Affiliated Party of any other Equity Contributor.

(b) Each Equity Contributor hereby agrees to defend, indemnify and hold the Borrower harmless from and against, any loss or liability to the Borrower resulting from a breach of Section 6.1(a) by any of its Equity Contributor Affiliated Parties (such reimbursement obligation, a “Recapture Indemnification Contribution”). Each Equity Contributor shall reimburse the Borrower for any loss or liability to the Borrower resulting from a breach of Section 6.1(a) by such Equity Contributor’s Equity Contributor Affiliated Parties. Recapture Indemnification Contributions due from an Equity Contributor shall be paid to

16

the Borrower within ten (10) days after the assessment of Recapture Damages becomes final and non-appealable.

(c) The amount of any Recapture Indemnification Contribution shall be net of any insurance proceeds or other funds received by the Borrower in consideration of any Equity Contributor’s breach of Section 6.1(a).

(d) If more than one Equity Contributor is directly responsible for Recapture Damages, the applicable Recapture Indemnification Contributions under Section 6.1(b), the responsible Equity Contributors shall be jointly and severally liable for the full amount of such Recapture Damages.

(e) At the time that any Recapture Indemnification Contribution is paid, the Equity Contributor providing such Recapture Indemnification Contribution shall provide the Loan Servicer, the other Equity Contributors and the Borrower with a written notice setting forth the amount of the funding provided.

(f) Any Equity Contributor may, at its election, deposit funds into the Cash Grant Recapture Liability Proceeds Account after it receives notice of potential Cash Grant Recapture Liability. Within thirty (30) days after a final, non-appealable determination of Recapture Damages, any excess funds on deposit in the Cash Grant Recapture Liability Proceeds Account over the sum (without duplication) of (x) actual Recapture Damages, and (y) Recapture Indemnification Contributions, shall be refunded to the contributing Equity Contributor. Monies refunded to the Equity Contributor from the Cash Grant Recapture Liability Proceeds Account will be shared by the Equity Contributor so that, to the greatest extent possible, the net amount paid by each Equity Contributor on account of a claim for Recapture Damages reflects the actual liability of each Equity Contributor for Recapture Indemnification Contributions.

(g) Each Equity Contributor shall provide to DOE on or before the Financial Closing Date an Equity Contribution Guaranty with respect to the obligation of such Equity Contributor to make Recapture Indemnification Contributions.

6.2 Notification of Recapture Damages.

(a) If at any time or from time to time the Borrower becomes aware that Cash Grant Recapture Liabilities exist or are reasonably likely to exist (other than on account of the acts or omissions of a Credit Party), it shall deliver a written notice and demand to the Equity Contributor(s) whose breach of Section 6.1(a) resulted in such Recapture Damages (with a copy to the Loan Servicer and the other Equity Contributors).

(b) If the Borrower fails to timely deliver all notices (in form and substance satisfactory to the Loan Servicer) required pursuant to Section 6.2(a), the Loan Servicer may, from time to time, deliver written notice and demand to the applicable Equity Contributor(s) (with a copy to the Borrower and the other Equity Contributors).

17

6.3 Defense of Recapture Claims

(a) Any Equity Contributor from which indemnity is demanded under Section 6.2 may, either on its own behalf or on behalf of the Borrower, appear in any proceeding relating to, and otherwise defend against, the imposition of Recapture Damages. The costs of such defense shall be at the expense of the defending Equity Contributor.

(b) Borrower and each Credit Party shall have the right, but not the obligation, to employ independent counsel (reasonably approved by the indemnitor- Equity Contributor) to represent it in any proceeding relating to the imposition of Recapture Damages and to the extent that the Borrower or a Credit Party determines in good faith that its rights and interests may be compromised or not fully and adequately represented by legal counsel acting for the indemnitor- Equity Contributor whether on account of any potential defenses that the indemnitor-Equity Contributor may have to its obligations under this Agreement or otherwise, and in such event the reasonable fees and expenses of Borrower or such Credit Party’s independent counsel shall be paid by the indemnitor- Equity Contributor.

6.4 Subrogation

(a) Any Equity Contributor that makes a payment pursuant to Section 6.1(b) shall be subrogated to the rights of the Borrower and Borrower shall pay over to such Equity Contributor any amounts it recovers for which the Equity Contributor made an indemnity payment. Such Equity Contributor may independently pursue its subrogation rights directly or in the name of the Borrower.

(b) Neither the Borrower nor any Credit Party shall take any action that will compromise an Equity Contributor’s subrogation rights or impose liability on an Equity Contributor without the prior written consent of such Equity Contributor.

6.5 Use of Recapture Indemnification Contributions

(a) Recapture Indemnification Contributions will be deposited into the Cash Grant Recapture Liability Proceeds Account or paid directly to the appropriate payee, as instructed by the party entitled to demand or direct indemnification.

(b) The obligations of an Equity Contributor to provide any Recapture Indemnification Contribution is separate and distinct from, and in addition to, (i) any Equity Contributor’s Base Equity Commitment required to be made in accordance with the Common Agreement and the other Loan Documents, and (ii) any other equity contributions made to the Borrower or any Equity Contributor Affiliated Party.

(c) The Parties hereto acknowledge that neither the Borrower, the Loan Servicer, the Collateral Agent nor DOE shall have any obligation to call for the provision of funds to the Borrower to cover Recapture Damages in accordance with this Article 6 and that neither the Borrower, the Loan Servicer, the Collateral Agent nor DOE shall be liable to any Person for not calling any funds or not calling sufficient funds under this Article 6.

18

6.6 Recapture Forbearance

Notwithstanding anything to the contrary in the Loan Documents, the Credit Parties will, in exercising remedies under the Loan Documents, use commercially reasonable efforts to avoid taking, directing or acquiescing to any action that is reasonably likely to result in the imposition of Cash Grant Recapture Liabilities.

6.7 Investment Tax Credit and Compensation Payments.

(a) If an investment credit under section 48 of the Code with respect to the Project is shown on IRS Form 3800 of any Equity Contributor or any Person holding a Proportional Ownership Interest in the Borrower through such Equity Contributor (together, “ITC Recipients”), and the Borrower shall not yet have received the Cash Grant, then within ten (10) days after the filing of an IRS Form 3800 by such ITV Recipient, the Equity Contributor that is the ITC Recipient (or through which the ITC Recipient holds a Proportional Ownership Interest in the Borrower) shall pay to the Borrower in cash an amount equal to the amount of such allowed investment tax credit (an “ITC Compensation Payment”).

(b) All ITC Compensation Payments received by the Borrower shall be deposited in the Cash Grant Proceeds Account and applied in accordance with Section 3.4.4 of the Common Agreement.

(c) Each Equity Contributor shall provide to DOE on or before the Financial Closing Date an Equity Contribution Guaranty with respect to the obligation of such Equity Contributor to make ITC Compensation Payments.

The Sponsor has authorized and reserved 1,275,578 shares of its common stock for the satisfaction of its obligations with respect to Supplemental Base Equity (the “Reserved BSE Common Equity”), which number of shares shall be the maximum number of shares the Sponsor will be required or entitled to issue pursuant to this Agreement. This number of shares of common stock constituting the Reserved BSE Common Equity was determined based on common stock valued at $6.79 per share based on the Sponsor’s most recent most recent BSE Common Equity 409A Valuation prior to the date of this Agreement.

7.1.4 Substitution of Security

If BrightSource Ivanpah shall not have made such Supplemental Base Equity Contribution in full within five (5) Business Days of such demand, the Loan Servicer may take the following actions:

(d) fourth, to the extent there remains any shortfall, instructing the Collateral Agent to require the Sponsor to issue shares of Reserved BSE Common Equity having a BSE Common Equity Contribution Value equal to such shortfall (but in no event more than the total number of shares of Reserved BSE Common Equity) and deliver them to the Collateral Agent as set forth in Section 7.3.2.

7.3.2 Issuance of Reserved BSE Common Equity

The number of shares of Reserved BSE Common Equity that the Sponsor is required to issue and deliver to the Collateral Agent pursuant to Section 7.3.1(d) shall be determined using (x) a value of $6.79 per share, (y) or, if the Sponsor has undergone an initial public offering, the average closing price of the Sponsor’s common stock over the immediately preceding seven (7) trading days (such value, the “BSE Common Equity Contribution Value”).

7.3.3 Accelerated Equity Contributions

Promptly upon delivery by the Loan Servicer to BrightSource Ivanpah at any time prior to the Supplemental Base Equity Commitment Security Release Date of a notice in the form of Exhibit A hereto demanding an Accelerated Equity Contribution pursuant to Section 8.2(f) of the Common Agreement, without further notice of default, presentment or demand for payment, protest or notice of non-payment or dishonor, or other notices or demands of any kind, all such notices and demands being waived, and without limiting the Sponsor’s obligations under Section 2.2.1, the Loan Servicer may immediately demand payment of the full amount of the Supplemental Base Equity Commitment Balance to the Collateral Agent, and may instruct the Collateral Agent to take any one or more of the actions specified in Section 7.3.1, in any specified order, and without regard to any time periods with respect to demands, in order to collect the full amount of the Supplemental Base Equity Commitment Balance, and the Loan Servicer shall instruct the Collateral Agent as to the Project Account into which any proceeds thereof shall be paid.

21

7.4 Grant of Security Interest

As security for the payment and performance of its obligations under this Agreement and the other Secured Obligations, BrightSource Ivanpah hereby grants to the Collateral Agent, for itself and on behalf of and for the ratable benefit of the other Secured Parties, a first priority perfected security interest in the Supplemental Base Equity Funding Account and all proceeds thereof (the “Supplemental Base Equity Collateral”).

If the Equity Contributor Guarantor fails to pay or perform any of its obligations hereunder when due, the Borrower, the Collateral Agent and each Credit Party may avail itself of all available remedies, in law or at equity, to enforce its rights hereunder. The assertion or employment of any right or remedy hereunder or otherwise shall not prevent the concurrent assertion of any other appropriate right or remedy.

(b) Nothing in this Guaranty, express or implied, shall give to any Person, other than the parties hereto, each Credit Party and their successors and permitted assigns hereunder and under the Loan Documents, any benefit or any legal or equitable right or remedy under this Guaranty.

6.2 Waiver of Subrogation

Notwithstanding any payment or payments made by the Equity Contributor Guarantor hereunder, or receipt of any amounts by the Collateral Agent or any Credit Party with respect to any of the Guaranteed Obligations, until the termination of the FFB Credit Facility Commitment and indefeasible payment and performance in full of all Secured Obligations (other than inchoate indemnity obligations), the Equity Contributor Guarantor shall not exercise any right or remedy arising by reason of any payment by it of, or amounts received by any Credit Party in connection with, the Guaranteed Obligations in accordance with Section 2 hereof, including the enforcement or acceptance of any payment by the Borrower, whether by subrogation or otherwise, against the Borrower, the Guaranteed Equity Contributor or any Credit Party.
