ARTICLE 2

PREFERRED SUPPLY PROJECTS

2.1 Definition of Preferred Supply Project. BSE shall designate Alstom as its preferred supplier for the Specified Equipment, with rights for Alstom, itself or any Alstom Affiliate, to offer to supply STEGs, SRSGs and Other Specified Equipment as provided in this Agreement (the “Preferred Supply Rights”), for the following Projects:

2.1.1 For Projects in which BSE is responsible for designating the supplier of the STEG and the SRSG, BSE shall grant Alstom the Preferred Supply Rights with respect to the STEG, the SRSG and any of the additional equipment listed on Exhibit G (and as more fully described in the Scope of Supply attached as Exhibit A) (collectively, the “Other Specified Equipment”), to the extent that BSE has responsibility for designating the supplier of the Other Specified Equipment. If BSE for any reason does not have responsibility for designating the supplier of any piece of Other Specified Equipment, it shall use its commercially reasonable efforts to have the party with such responsibility grant Alstom the Preferred Supply Rights with respect to any such piece of Other Specified Equipment.

2.1.2 For Projects in which BSE is not responsible for designating the supplier of the STEG or the SRSG, but is responsible for designating the EPC Contractor (and such EPC Contractor is responsible for designating the supplier of the STEG and the SRSG), BSE shall, as a condition to designating the EPC Contractor, require the EPC Contractor to grant Alstom the Preferred Supply Rights with respect to the STEG, the SRSG and the Other Specified Equipment.

2.1.3 For Projects in which BSE is not responsible for designating the supplier of the STEG, the SRSG or the EPC Contractor, BSE shall use commercially reasonable efforts to have the party with such responsibility grant Alstom the Preferred Supply Rights with respect to the STEG, the SRSG and the Other Specified Equipment. If, notwithstanding such commercially reasonable efforts, Alstom is not granted the Preferred Supply Rights, BSE’s obligations under this Agreement shall not apply to such Project.

Any Project for which Alstom has been granted the Preferred Supply Rights shall be referred to herein as a “Preferred Supply Project.” The Parties agree that the Ivanpah Projects shall not be Preferred Supply Projects.

2.2 Number of Preferred Supply Projects. BSE’s obligations to grant the Preferred Supply Rights to Alstom under this Agreement shall apply until the Exclusive Project Limit has been reached. A Preferred Supply Project shall be counted toward the Exclusive Project Limit in each of the following circumstances:

2.2.1 when Alstom has entered the applicable Equipment Supply Agreements for the Project, and financial closing for such Project has occurred;

7

Confidential Document December 27, 2010

2.2.2 when Alstom has been granted the Preferred Supply Rights but has, in whole or in part, elected not to supply equipment;

2.2.3 when Alstom has provided a Supply Offer, but did not proceed to one or more Equipment Supply Agreements because the Supply Offer, in whole or in part, was determined to be uncompetitive pursuant to the procedures of ARTICLE 4; or

2.2.4 when Alstom has provided a Supply Offer that has not yet resulted in an Equipment Supply Agreement, provided that: (a) in case of a third party project involving a competitive tender, until a third party has been awarded the tender in a final manner; and (b) with respect to any Preferred Supply Project, for so long as BSE can show that permitting and financing of the Project are being actively pursued. In any event, if a Supply Offer does not result in related executed Equipment Supply Agreement(s) within [*] of the Supply Offer, the Supply Offer will no longer be credited against the Exclusive Project Limit and the provisions of this Agreement will be reinstituted going forward with respect to the size and number of the Preferred Supply Projects covered by such Supply Offer. After reaching the Exclusive Project Limit, BSE may enter into discussions with another party for a Project that would otherwise be a Preferred Supply Project hereunder, and such Project shall not be subject to this Agreement notwithstanding any reinstitution of this Agreement pursuant to the provisions of this Section 2.2.4.

2.3 Exceptions. The obligations of BSE to grant Alstom the Preferred Supply Rights do not apply when and to the extent that:

(a) following ten (10) business days after a written request by BSE for a particular Project as provided in Section 3.1, Alstom has not confirmed in writing that Alstom or an Alstom Affiliate can deliver the STEG and/or the SRSG requested by BSE for the related Project at BSE’s requested time of delivery in accordance with this Agreement; provided always that BSE has requested an offer for such Project from Alstom (or an Alstom Affiliate) within the range of time of delivery as set forth in the Key Terms and otherwise in keeping with this Agreement, and provided further that, notwithstanding the foregoing, Alstom shall be granted the Preferred Supply Rights if no third party supplier has offered a time of delivery for such STEG and/or SRSG, as applicable, earlier than that proposed by Alstom (or an Alstom Affiliate);

(b) the supply of the STEG and/or the SRSG by Alstom or any Alstom Affiliate is prohibited in a definite manner by local law or by permit requirements for a particular Project (provided always that, to the extent BSE has control over the permitting process for such Project, it will use commercially reasonable efforts to have such permits allow supply of the STEG and/or the SRSG by Alstom or an Alstom Affiliate), in which case such Project shall not be a Preferred Supply Project.

2.4 Non-Preferred Supply Projects. If a Project is not a Preferred Supply Project because, for example, BSE does not have the ability to designate or otherwise arrange for Alstom to have the opportunity to be the supplier of both the STEG and the SRSG, BSE may (but shall have no obligation to) offer Alstom the opportunity to supply the equipment available to supply, but such supply shall not be credited toward the Exclusive Project Limit.

2.5 [*] Design and Development

(a) [*] Agreement. The Parties will diligently work together to enter into an agreement setting forth the Parties’ intentions relating to the [*] design and development (the “[*] Agreement”).

(b) BSE Information and Support for [*] Development. The Parties acknowledge that, in order for Alstom to be capable of supplying [*] to Preferred Supply Projects within [*], (i) BSE (directly or through its Affiliates) must supply certain data and other information regarding its technology, and provide support to Alstom’s [*] design and development activities and (ii) Alstom may have to begin certain design and development activities regarding [*] prior to finalization and execution of the [*] Agreement. If BSE does not provide the information and support as reasonably required by Alstom and, as a result, Alstom is not able to supply [*] for a Preferred Supply Project, such Preferred Supply Project shall not be credited toward the Exclusive Project Limit notwithstanding Alstom supplying [*].

(c) Intellectual Property. The [*] Agreement shall set out the terms and conditions for the ownership, and right of use, of IP relating to [*] development activities, including the Parties’ respective ownership of new IP created in the course of the collaboration on the development and design of [*], and taking into account the principles set forth on Exhibit I. The Parties acknowledge and agree that the principles set forth in Exhibit I shall apply regardless of whether or not the [*] Agreement is executed. However, upon execution of the [*] Agreement, in case of a conflict between the terms of Exhibit I and the terms of the [*] Agreement, the provisions of the [*] Agreement shall prevail.

ARTICLE 3

SUPPLY OFFERS AND KEY TERMS

3.1 Supply Offer

3.1.1 For each Preferred Supply Project or group of Preferred Supply Projects, BSE shall notify Alstom what Other Specified Equipment is included in the supply opportunity. As provided in Section 2.3(a), Alstom shall notify BSE within ten (10) business days of BSE’s notice of the Preferred Supply Project(s) which of the applicable Specified Equipment Alstom (itself and/or an Affiliate) will be capable of supplying. For any Specified Equipment that Alstom has indicated it is capable of supplying, within a reasonable time period following receipt of BSE’s notice of the Preferred Supply Project, Alstom (or an Alstom Affiliate designated by Alstom) shall provide an offer to BSE to supply such Specified Equipment (each such offer, a “Supply Offer”) in the form of one or more proposed Equipment Supply Agreements including, with respect to each type of Specified Equipment proposed to be supplied, (a) technical offer, (b) price (taking into account any volume discounts for procurement of multiple pieces of such

Specified Equipment), (c) payment and delivery terms, payment and performance security, liability for delay and performance, warranties, indemnities, cancellation costs, insurance, taxes and duties and limitations of liability as set forth in Exhibit B (the “Key Terms”), and (d) other terms and conditions of supply.

3.1.2 Unless the seller under the contemplated Equipment Supply Agreement is Alstom or an entity with equivalent creditworthiness of Alstom, the Supply Offer shall confirm that an affiliated company guarantee from Alstom (or an entity with equivalent creditworthiness), substantially in the form set out in Exhibit F, will be provided to the purchaser upon execution of the Equipment Supply Agreement.

3.2 Price

3.2.1 The price for the Specified Equipment specified in each Supply Offer shall be competitive in the market where the related Preferred Supply Project is located, and the other terms shall be consistent with the Key Terms (unless and to the extent the Parties mutually agree to vary any particular term of the Key Terms). If BSE has reasonable cause to believe that the price specified in a Supply Offer is not in line with the foregoing, BSE may request a review pursuant to ARTICLE 4.

3.2.2 The Parties may expressly agree to use a reference price as a basis for future pricing of particular pieces of Specified Equipment supplied pursuant to this Agreement (the “Reference Prices”). The Parties agree that each such Reference Price, in combination with the applicable Key Terms, shall be deemed to be competitive under the circumstances when such Reference Price is agreed. Notwithstanding the foregoing, the Parties agree that a Supply Offer may include prices which deviate from the Reference Prices, and the competitiveness of such Supply Offer shall be evaluated as specified in Section 4.2. For the sake of clarity, the Parties acknowledge that they may define different Reference Prices for STEGs of different sizes, i.e., a Reference Price for [*] and a different Reference Price for [*], along with corresponding different Reference Prices for Other Specified Equipment sized to such STEGs.

ARTICLE 4

REVIEW PROCESS

If BSE requests a review of any price specified for a piece of Specified Equipment in a Supply Offer pursuant to Section 3.2, BSE shall within [*] of receiving the Supply Offer, deliver a notice to Alstom requesting such review (a “Price Review Notice”), and the competitiveness of the Supply Offer with respect to the applicable piece of Specified Equipment shall be reviewed pursuant to the procedure in this ARTICLE 4. BSE may dispute the competitiveness of a Supply Offer with respect to any one or more pieces of Specified Equipment described in any Supply Offer.

4.1 Absence of Reference Price. If no Reference Price has been established for the applicable Specified Equipment in accordance with Section 3.2.2, the following procedure shall apply:

4.1.1 BSE’s Price Review Notice shall provide reasons and supporting data (to the extent reasonably obtainable in the period from receipt of the Supply Offer until the Price Review Notice is due) for BSE’s opinion and specify the elements of the Supply Offer which BSE considers not to be competitive.

4.1.2 If the Parties cannot agree on a new price for the applicable Specified Equipment within [*] of Alstom’s receipt of the Price Review Notice, then either Party shall be entitled to request the appointment of an independent third party expert (an “Expert”) to evaluate the applicable portion of the Supply Offer. The Parties agree that [*] are acceptable Experts (the “Expert Pool”) for purposes of this ARTICLE 4. The Expert shall be nominated pursuant to the following procedure:

4.1.2.1 The Party requesting the appointment of an Expert in accordance with the above shall send a notice to the other Party including the proposed Person, chosen from the Expert Pool, to act as Expert;

4.1.2.2 Within [*] of receiving the requesting Party’s notice in accordance with Section 4.1.2.1 above, the other Party shall notify the requesting Party stating whether (i) it agrees to such Person acting as Expert or (ii) it vetoes such Person (without need to provide any reason), in which case it shall propose another Person, chosen from the Expert Pool, to act as Expert;

4.1.2.3 If the other Party exercised its right of veto pursuant to Section 4.1.2.2 item (ii) above, the requesting Party shall within [*] of receiving the response pursuant to Section 4.1.2.2 above, notify the other Party whether (i) it agrees with the Person proposed by the other Party, in which case such Person shall be appointed as Expert or (ii) it refuses such Person, in which case the requesting Party shall nominate a different Person from the Expert Pool who shall be appointed as Expert.

For the avoidance of doubt, to the extent that both Parties expressly agree, the Parties may agree on a Person outside the Expert Pool who has a sound technical expertise and is knowledgeable in the field of the applicable Specified Equipment and solar thermal technology, to act as Expert.

If the Parties are unable to agree on a new price and terms after such [*]period, then BSE shall be entitled to solicit third party offers for the applicable Specified Equipment as provided in Section 4.1.6.

4.1.5 The costs of the Expert’s services shall be paid (i) by Alstom if the price specified in the Supply Offer for the applicable Specified Equipment is more than [*]% of the Market Price and (ii) by BSE if said price is less than or equal to [*]% of the Market Price. If an advance needs to be paid to the Expert, each Party shall pay 50%, and upon determination of the Market Price by the Expert the Party that has to bear the costs pursuant to the foregoing sentence shall reimburse the other Party for the other Party’s portion of any advance paid.

4.1.6 If the Expert determines that the Supply Offer is not competitive as provided in Section 4.1.4 and the Parties are unable to agree on a new price and terms during the [*] period referenced in Section 4.1.4, BSE may solicit third-party offers for supplying the applicable Specified Equipment to the Preferred Supply Project to which the Supply Offer related. In soliciting third party offers, BSE shall follow an open and transparent bidding process using pre-defined evaluation criteria and shall continue to include Alstom as a bidder in that process, without prejudice. Once the bids have been received, BSE shall review the bids and select the most competitive bid based on price and other terms corresponding to the Key Terms. BSE may not award the tender to a third party if the price and terms offered by such third party are not more favourable to BSE than those for the applicable Specified Equipment in the Supply Offer. Should the tender be awarded to a third party, BSE shall provide Alstom for information purposes only with feedback consistent with the evaluation criteria, but subject to usual confidentiality restrictions in the respective bids. Such feedback information provided to Alstom shall include as a minimum the difference between the Supply Offer for the applicable Specified Equipment (or, as the case may be, the revised bid submitted by Alstom or relevant Alstom Affiliate in the bidding process) and the other bids received, on a no-name basis, in terms of delivery lead time, performance guarantees, price and warranties, using, for STEGS the standard bid ranking matrix, a form of which is attached hereto as Exhibit E, and for any other Specified Equipment any such similar bid ranking matrix.

4.2 Existing Reference Price. If and to the extent that the Parties have defined a Reference Price for the applicable Specified Equipment, the procedure described in this Section 4.2 shall apply in lieu of the procedure described in Section 4.1.

4.2.1 BSE’s Price Review Notice shall specify the following, and shall provide reasons and supporting data for BSE’s opinion as follows:

4.2.1.2 If BSE is of the opinion that the price specified in a Supply Offer for the applicable Specified Equipment should be lower by reason of the existence of reducing factors, BSE shall provide in the Price Review Notice reasons that such decrease is in keeping with price decreases in the relevant market.

4.2.2 Within [*] of receiving a Price Review Notice in accordance with Section 4.2.1, Alstom shall provide a written response to the Price Review Notice (the “Price Review Response”), whereby Alstom either:

4.2.2.1 provides BSE with a revised price; or

4.2.2.2 provides BSE with the reasons for the price initially quoted in the Supply Offer, i.e.:

(a) to the extent the Price Review Notice questions a price increase, Alstom shall provide BSE with the reasons for such increase;

(b) if a price decrease is requested in the Price Review Notice based on reducing factors, Alstom shall provide reasons why in its opinion such factors do not justify a price decrease.

4.2.2.3 The Price Review Response may combine a revised price as per Section 4.2.2.1 and reasons as per Section 4.2.2.2.

4.2.3 Within [*] of receiving the Price Review Response, BSE shall notify Alstom whether it accepts the revised price and/or explanations (as applicable) provided in the Price Review Response.

4.2.4 If the Parties cannot agree on the price within [*] of BSE’s receipt of the Price Review Response, then either Party shall be entitled to request the appointment of an Expert in accordance with the procedure set forth in Section 4.1.2.

4.2.5 The Expert shall, within [*] from the date of his or her appointment, evaluate the changes that have occurred in the market since the establishment of the applicable Reference Price (including commodity and other price indices, overall equipment supply and demand, exchange rates, etc., in each case as relevant to the applicable Specified Equipment); in doing so the Expert shall consider the Parties’ respective reasons provided pursuant to Section 4.2.1 and Section 4.2.2, if any. [*]

4.2.6 If the price specified in the Supply Offer for the applicable Specified Equipment (as such price may have been revised pursuant to Section 4.2.2) is less than or equal to [*] of the Reference Price adjusted according to the Market Change Percentage (the “Adapted Reference Price”), then the applicable portion of the Supply Offer shall be deemed competitive.

If the price specified in the Supply Offer for the applicable Specified Equipment (as such price may have been revised pursuant to Section 4.2.2) is more than [*] of the Adapted Reference Price, then the Parties shall enter into additional discussions for a period of [*] to attempt to improve the price to make it acceptable to BSE. If Alstom adjusts its price for the applicable Specified Equipment to [*], then such price shall be deemed acceptable to BSE. If the Parties are unable to agree on a new price and terms after such [*] period, then BSE shall be entitled to solicit third party offers for the applicable Specified Equipment as provided in Section 4.1.6.

4.2.7 The costs of the Expert’s services shall be paid (i) by Alstom if the price specified in the Supply Offer for the applicable Specified Equipment is more than [*] of the Adapted Reference Price and (ii) by BSE if said price is less than or equal to [*] of the Adapted Reference Price.

To the fullest extent permitted by law, each Party shall indemnify, defend and hold harmless the other Party, its Affiliates, and its or their officers, directors, employees, agents and representatives against and from any losses, damages, costs, expense, fines, charges and liabilities suffered or incurred by any such Person to the extent arising out of, or resulting from third party claims against such Person arising from the first Party’s negligence or breach of this Agreement. If any legal proceedings are instituted or any claim or demand is asserted by any third party in respect of which indemnification may be sought under this Section 8.1, the indemnified Party shall, within twenty (20) days of actual receipt thereof by a responsible officer, cause written notice of such legal proceedings or the assertion of such claim or demand to be forwarded to the indemnifying Party, specifying the nature of such legal proceedings, claim or demand and the estimated amount thereof to the extent feasible. The indemnifying Party shall have the right, at its option and its own expense, to be represented by counsel of its choice and to participate in, or take control of, the defense, negotiations and/or settlement of any proceeding, claim or demand that relates to any amounts indemnifiable or potentially indemnifiable under this Section 8.1.

FORM OF ALSTOM POWER INC. GUARANTEE

THIS GUARANTEE is made on the _________________

BY

ALSTOM Power Inc., a Delaware corporation with registered office at 000 Xxxxx Xxxx Xxxxx, 00000 Xxxxxxx, Xxxxxxxxxxx, Xxxxxx Xxxxxx of America, the “Guarantor”

IN FAVOUR OF

[ — ] [BSE or other Buyer under the relevant Equipment Supply Agreement], the “Beneficiary”

WHEREAS:

(A) By that certain Equipment Supply Agreement, dated [ — ] (the “Contract”), between the Beneficiary and [ — ] [Name and registered office of Alstom entity acting as Seller under the relevant Equipment Supply Agreement] (the “Seller”), the Seller has agreed to deliver [describe quantity and pieces of Equipment to be delivered] (the “Equipment”) upon the terms and conditions set forth in the Contract;

(B) At the request of the Beneficiary and pursuant to Section 3.1 of that certain Amended and Restated Preferred Equipment Supply Agreement, dated [ — ], the Guarantor has agreed to guarantee due performance of the Contract by the Seller as set out herein.

IN CONSIDERATION OF THE ABOVE PREMISES, IT IS HEREBY AGREED AS FOLLOWS:

Capitalized words and expressions used herein shall, unless otherwise defined, have the same meanings as are ascribed thereto in the Contract.

In consideration of the Beneficiary entering into the Contract with the Seller, the Guarantor hereby irrevocably guarantees to the Beneficiary due performance by the Seller of all of its obligations and liabilities under and in accordance with the Contract, as set out herein below (the “Guaranteed Obligations”):

(1) If at any time the Seller fails or has failed to perform any of its obligations under the Contract, the Guarantor shall perform (or procure the performance of) the Seller’s obligations under the Contract and shall pay any sums that may be payable under the

F-1

Confidential Document December 27, 2010

Contract as a result of the non-performance by the Seller of any of its obligations thereunder, after receipt of a written demand from the Beneficiary (the “Demand”) provided that (i) the Demand is accompanied by a written statement issued by the Beneficiary that Seller has failed to fulfill its obligations under the Contract enclosing all relevant details of the alleged failure and that (ii) a corresponding Demand has first been made to the Seller pursuant to the Contract. A Demand, or payment or performance of less than all of the Guaranteed Obligations in response thereto, shall in no event limit the Beneficiary’s right to assert additional Demands or the Guarantor’s obligation to pay or perform such additional Demands, subject always to the limitations set out in this Guarantee including without limitation the Cap. Except if and to the extent that the sums claimed in the Demand are disputed by the Guarantor, payment under this Guarantee will be made by the Guarantor by federal wire transfer or in accordance with any such other reasonable wire instructions notified by the Beneficiary to Guarantor, within [*] following receipt of the Beneficiary’s Demand in accordance herewith; provided, that if such disputed amounts are ultimately determined to be payable under the Guarantee, interest shall be due on the withheld amounts to the extent payable by Seller under the Contract.

(2) Notwithstanding anything to the contrary herein, in no event shall the obligations and liabilities of the Guarantor hereunder be greater, either in the cumulative aggregate or in respect of any individual claim, than the obligations and liabilities of the Seller under the Contract and the Guarantor’s cumulative liability hereunder shall be limited at all times to [ — ] [[*]] (the “Cap”). The Guarantor shall be entitled to all defenses, limitations, remedies and exclusions available to the Seller under, or otherwise with respect to, the Contract, and the Guarantor shall be entitled to assert any counterclaim to the same extent that the Seller would be entitled to assert with respect to such payment or performance of any obligations, except for defenses arising out of the bankruptcy, insolvency, dissolution or liquidation of Seller, the power or authority of Seller to enter into the Contract, and to perform its Guaranteed Obligations thereunder.

If applicable (in case of more than one piece of Equipment): The Cap shall automatically be reduced pro rata of the value of each piece of Equipment at the date when the Warranty Period relating to each such piece of Equipment expires.

The obligations of Guarantor contained herein are not conditioned in any way upon the institution of suit or the taking of any other action (except as expressly provided in Section 1 hereof), or attempt to enforce performance of or compliance with the Guaranteed Obligations. If and to the extent any payment made pursuant to the Guaranteed Obligations under the Contract is deemed to constitute liquidated damages, Guarantor and the Beneficiary acknowledge and agree that such damages are difficult or impossible to determine and that such payment constitutes a reasonable approximation of the amount of such damages, and not a penalty.

(3) This Guarantee shall extend to any variation of or amendment to the Contract and to any agreement supplemental thereto agreed between the Beneficiary and the Seller, being however specified that the Guarantor’s cumulative liability hereunder shall be limited at all times to the Cap set out in Section 2.

(4) Guarantor hereby waives without impairing or releasing the obligations of Guarantor hereunder:

a. notice of acceptance of this Guarantee, notice of creation or existence of any of the obligations under the Contract and notice of any action by the Beneficiary in reliance hereon or in connection herewith;

b. notice of or consent to the entry into the Contract by the Seller and the Beneficiary and any amendments thereto, including but not limited to changes in the manner, place, or terms of payment or performance of any or all of the Guaranteed Obligations (subject always to limits set out in this Guarantee including without limitation Sections 2 and 14); and

c. notice of or consent to any increase, reduction or rearrangement of the Seller’s obligations under the Contract or any extension of time for the payment of any sums due and payable by the Seller to the Beneficiary under the Contract, it being understood that the Guarantor’s cumulative liability hereunder shall in no event be greater than the Cap;

provided, however, that Guarantor does not waive any notice requirement which must be given by the Beneficiary and received by the Seller in accordance with the terms of the Contract, the giving of which and the passage of any related notice or grace period being required in order for a payment obligation by the Seller to be due and payable under the Contract for non-payment.

(5) Guarantor agrees that Guarantor’s liability to the Beneficiary hereunder shall not be released or impaired by the occurrence of any one or more of the following events:

a. the insolvency, bankruptcy, reorganization or receivership of Guarantor or Seller;

b. the exercise, failure to exercise or delay by the Beneficiary to exercise, in whole or in part, any right or remedy held by the Beneficiary against Seller or Guarantor with respect to the Contract or this Guarantee; provided, however, that nothing herein shall be construed to waive any applicable statute of limitations or permit Beneficiary to recover amounts from both Seller and Guarantor for the same portion of the same claim;

c. the sale, encumbrance, transfer or modification of the ownership of Guarantor or Seller, or any change in the financial condition or management of Guarantor or Seller;

d. any lack of consideration with respect to the Contract or this Guarantee and any and all amendments thereof;

e. any lack of corporate power or authority of Guarantor or Seller; or

f. except to the extent specifically provided in this Guarantee, any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor.

(6) The Guarantor’s obligations as guarantor shall be in addition to and independent from every other security which the Beneficiary may at any time hold in respect of any of Seller’s obligations under the Contract. However, the Beneficiary shall not be entitled to enforce its rights and claims under this Guarantee to the extent that the Beneficiary has already received payment or discharge under any other security that the Guarantor may hold in respect of the Seller’s obligations which are secured by this Guarantee.

b. The Guarantor has all necessary power and authority to execute, deliver and perform or procure the performance of this Guarantee;

c. The Guarantor has duly executed and delivered this Guarantee and this Guarantee constitutes its legal, valid and binding obligations in accordance with its terms;

e. Each of the waivers and consents set forth in this Guarantee are made voluntarily after consultation with legal counsel and with full knowledge of their significance and consequences. If, notwithstanding the intent of the parties that the terms of this Guarantee shall control in any and all circumstances, any such waivers or consents are determined to be unenforceable under the applicable law, such waivers and consents shall be effective to the maximum extent permitted by such applicable law.

(8) Subject to the limitation set forth herein including without limitation Section 2, there shall be full recourse to Guarantor for the Guaranteed Obligations, but in no event shall any owner, member, partner, shareholder, officer, director, employee or affiliate (other than Seller) of Guarantor be personally liable or obligated for the Guaranteed Obligations.

(9) The obligations of Guarantor under this Guarantee shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of Guarantor in respect of the Guaranteed Obligations is rescinded or must be otherwise restored by the Beneficiary, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, all subject to the limitations set out herein.

(10) Except as otherwise provided in this Guarantee, each remedy, right, and power granted to the Beneficiary or allowed it by applicable law shall be cumulative and not exclusive of any other and may be exercised by the Beneficiary from time to time.

(11) This Guarantee and the undertakings contained herein shall be binding upon the successors of the Guarantor, and are provided for and shall inure to the benefit of the Beneficiary and its successors. The Beneficiary may not assign, charge or transfer any rights, title or benefits under this Guarantee without the prior written consent of the Guarantor, such consent not to be unreasonably withheld, conditioned or delayed; provided, that this Guarantee shall automatically be assigned, subject to written notice to the Guarantor, upon assignment by the Beneficiary of the Contract (a) to an affiliate of BrightSource Energy, Inc.; or (b) to any other assignee of the Beneficiary under the Contract, where the Guarantor has given its consent to such assignment; [if applicable: or (c) to [identified lender in the applicable Project’s project financing scheme]], in each case in accordance with the Contract’s terms.

(13) Any dispute, controversy or claim arising out of or relating to this Guarantee, or the interpretation, breach, termination or validity hereof, shall be resolved at the first instance through consultation between the Guarantor and the Beneficiary. If such dispute, controversy or claim is not resolved within thirty (30) days following the date on which notice of the same has been given by either of the Beneficiary or the Guarantor to the other, said dispute, controversy or claim shall be submitted to confidential, binding arbitration at the request of either of the Beneficiary or the Guarantor with notice to the other party.

The award rendered by the arbitrators shall be final and binding and may be entered and enforced as a final judgment in accordance with New York law in any court of competent jurisdiction.

(14) This Guarantee shall automatically expire when all the said obligations of the Seller shall have been performed in accordance with the Contract, and in any case no later than [ — ] [[*]]. As from the expiration of this Guarantee, the Guarantor shall have no further obligations or liability under this Guarantee, whether or not this Guarantee is returned to the Guarantor.

(15) The invalidity, illegality or unenforceability in whole or in part of any of the provisions of this Guarantee shall not affect the validity, legality and enforceability of the remaining part or provisions of this Guarantee.
