(a) Permitting. Seller, at its sole cost and expense, shall timely take all commercially reasonable and diligent steps necessary to obtain or cause to be obtained all Permits required to construct, maintain or operate the Facility in accordance with the

requirements of this Agreement and all applicable Requirements of Law including but not limited to the timely preparation of all environmental documents required to have the Facility reviewed under applicable federal and Utah law (the “Environmental Documents”).

(b) Project Design. The location, design, configuration and capacities of the Facility shall be consistent with the requirements of this Agreement and all applicable Requirements of Law, including but not limited to the characteristics and other requirements for the Facility set forth in Appendix B, and also subject to any conditions that are imposed by the lead agency or any responsible agency as part of the environmental review of the Facility required under applicable Utah law and such conditions that Seller deems acceptable.

(c) Meetings With Governmental Authorities. Seller shall represent the Facility as necessary in all meetings with and proceedings before all Governmental Authorities.

(d) CEQA Exemption. The Parties acknowledge and agree that the Facility is subject to environmental review pursuant to NEPA, and is therefore statutorily exempt from CEQA pursuant to Title 14, California Code of Regulations, Section 15277. The Parties acknowledge and agree that Seller shall have no obligation to sell and Buyer shall have no obligation to purchase any Energy under this Agreement unless and until a notice of exemption pursuant to Title 14, California Code of Regulations, Section 15277 (“Notice of Exemption”), shall have been duly filed in the appropriate state and county, and the applicable period for any legal challenges to any action by any such agency or any other Person, including the statute of limitations pertaining to the filing of the Notice of Exemption, shall have expired without any such challenge having been filed or, in the event of any such challenge, the challenge shall have been determined adversely to the challenger by final judgment or by settlement. Buyer agrees to make the requisite filings in the appropriate state and county.

(e) Development and Construction of the Facility. Seller shall use commercially reasonable and diligent efforts to site, develop, finance and construct the Facility. The Facility shall be owned by Seller during the Agreement Term. Seller shall develop, finance and construct the Facility, at its sole risk and expense, and in compliance with the requirements of this Agreement, all applicable Requirements of Law, Prudent Utility Practices, and applicable manufacturer’s and vendor’s specifications and recommended procedures; provided that meeting these requirements shall not relieve Seller of its other obligations under this Agreement.

(f) Confirmation of Facility Premises. Seller agrees and acknowledges that (i) Seller’s agents and representatives have visited, inspected and are familiar with the Facility Premises, its surface physical condition relevant to Seller’s obligations under this Agreement, including surface conditions, normal and usual soil conditions, roads, utilities, and topographical, air and water quality conditions; (ii) Seller is familiar with all local and other conditions which may be material to Seller’s performance of its obligations under this Agreement (including, transportation, seasons and climate, access, weather, handling and storage of materials and equipment; and availability and quality of labor and utilities); and (iii) based on the foregoing, the Facility Premises constitute an acceptable and suitable site for the construction and operation of the Facility in accordance herewith. Any failure by Seller to take the actions described in this Section will not relieve Seller from any responsibility for estimating properly the difficulty and cost of successfully constructing, maintaining or operating the Facility in accordance with this

Agreement or from proceeding to construct, maintain and operate the Facility successfully without any additional expense to Buyer.

Section 3.2 Certification of Commercial Operation Date; Preliminary Notice. Seller shall furnish Buyer at least ninety (90) days prior to the anticipated Commercial Operation Date a notice of such anticipated Commercial Operation Date. Seller shall provide Buyer with a notice when Seller believes that all conditions precedent to achieving Commercial Operation as specified in the definition of “Commercial Operation” in Section 1.1 have been satisfied.

Section 3.3 Other Information. Seller shall provide to Buyer such other information that is in the possession of Seller or its Affiliates or is reasonably available to Seller regarding the permitting, engineering, construction or operations of Seller, its subcontractors or the Facility, and other data concerning Seller, its subcontractors or the Facility that Buyer may, from time to time, reasonably request in writing, subject to Seller’s obligations of confidentiality to third parties with respect to such information. Until the Commercial Operation Date, Seller shall provide to Buyer monthly written reports describing permitting and development activities in the previous month and anticipated progress and activities for the upcoming month with respect to the Facility.

Section 3.4 Milestone Schedule. Seller has provided Buyer with the milestone schedule set forth in Appendix B for the development of the Facility. Seller shall use commercially reasonable efforts to achieve each milestone set forth on Appendix B (each, a “Milestone”) by the date specified therefor, subject to extension in accordance with this Agreement. Seller shall include in its weekly reports to Buyer the status of each Milestone. In the event that Seller anticipates that it will not achieve any Milestone by the date set forth in Appendix B, Seller shall, in its weekly report to Buyer, notify Buyer of any anticipated delay in achieving a Milestone, state the basis for such delay, outline the steps that Seller is taking to address the delay, and propose a revised date for achievement of the Milestone.

Section 3.5 Liquidated Damages.

(a) If Seller fails to achieve Commercial Operation of the Facility by the Guaranteed Commercial Operation Date, Seller shall pay liquidated damages to Buyer in an amount equal to $5,000 per day for the first thirty (30) days, and $19,375 per day thereafter, up to a maximum of $4,800,000 in the aggregate, for each day intervening between the Guaranteed Commercial Operation Date for the Facility and the earlier of (x) the Commercial Operation Date, and (y) the date, if any, on which this Agreement is terminated by Buyer pursuant to Section 14.4(a).

(b) On the Effective Date, Seller shall cause First Wind, or an Affiliate of First Wind (other than Seller) to apply for and cause to be issued to Buyer, as the beneficiary thereunder, and thereafter to maintain and replace, until such time as Seller achieves Commercial Operation of the Facility, a letter of credit in the amount of $4,800,000 issued by a Qualified Issuer, substantially in the form attached hereto as Appendix M, or such other form as is acceptable to Buyer, which shall secure Seller’s obligations to pay liquidated damages under Section 3.5(a) (the “LD Security”), all in accordance with the terms and provisions of the agreement referred to in Section 2.1(c).

(c) Each Party agrees and acknowledges that (i) the damages that Buyer would incur due to Seller’s delay in achieving Commercial Operation by the Guaranteed Commercial Operation Date would be difficult or impossible to predict with certainty, and (ii) it is impractical and difficult to assess actual damages in the circumstances stated and, therefore, the delay liquidated damages as agreed to by the Parties and set forth herein are a fair and reasonable calculation of such damages.

Section 3.6 Additional Capacity after Early Completion in the Early Completion Facility Configuration. In the event that Seller shall achieve Commercial Operation in the Early Completion Facility Configuration, then Seller shall nevertheless have the right to install additional wind turbines (for a maximum installed capacity of 102 MW) up to ninety (90) days following the Commercial Operation Date. Seller shall have the right to modify the Facility configuration shown in Appendix B to incorporate additional wind turbines installed and completed after achievement of Commercial Operation of the Facility in the Early Completion Facility Configuration by providing written notice to Buyer at the Commercial Operation Date. Any such installation of additional wind turbines shall satisfy all of the conditions set forth in the definition of Commercial Operation and shall have no effect on the Prepayment Amount.

Section 3.7 Decommissioning and Other Costs. If Buyer elects to purchase the Facility pursuant to this Agreement, (including pursuant to Section 15.21), Buyer shall be responsible for all costs of decommissioning or demolition of the Facility or any environmental or other liability associated with the decommissioning or demolition without regard to the timing or cause of the decommissioning or demolition. If Buyer elects not to purchase the Facility pursuant to this Agreement, Buyer shall not be responsible for any costs of decommissioning or demolition of the Facility or any environmental or other liability associated with the decommissioning or demolition.

Seller shall deliver the Facility Energy to Buyer, and Buyer, or its designee, shall receive such Facility Energy from Seller, under this Agreement at the Point of Delivery. Seller will be responsible for all losses to the Point of Delivery. Buyer will be responsible for all losses from the Point of Delivery.

Section 4.2 Interconnection Agreement. Intermountain Power Agency and Milford I have entered into an interconnection agreement that defines the equipment to be installed at the Point of Delivery to interconnect the Facility at the Point of Delivery thereof, and which provides Buyer with rights as a third party beneficiary thereunder. Seller shall have received an assignment from Milford I of the interconnection rights and ownership interests in interconnection facilities necessary for the interconnection of the Facility at the Point of Delivery and shall enter into an Interconnection Agreement with Intermountain Power Agency and/or an amended Interconnection Agreement among Milford I and Intermountain Power Agency for the interconnection of the Facility to the Point of Delivery (the “Interconnection Agreement”) which shall provide Buyer with rights as a third party beneficiary thereunder as may be reasonably requested by Buyer. In addition, Seller shall provide evidence satisfactory to Buyer of the consent and release by or on behalf of the lenders providing financing to Milford I, if

applicable, for the Milford Wind Phase I Facility of the transfer by Milford I to Seller of the rights, title and interests under the Interconnection Agreement which are necessary for the Facility and the Related Interests and Rights which rights, title and interests were transferred and assigned as security by Milford I to such lenders.

Section 4.3 Transmission Service Agreement. Seller shall, at Seller’s sole cost and expense, arrange transmission service, pursuant to the applicable OATTs, which would enable Seller to sell Facility Energy to other parties during any period as described in Section 7.4.

ARTICLE V

OPERATION AND MAINTENANCE OF THE FACILITY

Section 5.1 Compliance with Electrical Service Requirements. Seller shall, at its sole expense, operate and maintain the Facility: (i) in accordance with Prudent Utility Practices, the requirements of this Agreement, all applicable Requirements of Law, the requirements of applicable manufacturer’s and operator’s specifications and, using commercially reasonable efforts to comply with any published recommendations of the manufacturers and suppliers of the wind turbines and other major components of the Facility; (ii) with due regard for the safety, security and reliability of the interconnection facilities, Transmission Line and Transmission System and in accordance with the Buyer’s system protection design requirements, attached hereto as Appendix P, and (iii) in a manner that is reasonably likely to maximize the output of Energy from the Facility and result in a useful life for the Facility of not less than twenty (20) years.

Section 5.2 General Operational Requirements. In addition to the requirements set forth in Section 5.1 and elsewhere in this Agreement, Seller shall, at all times employ or cause to be employed qualified and trained personnel for managing, operating and maintaining the Facility and for coordinating with Buyer and Buyer’s Agent. Seller shall ensure that necessary personnel are available on-site or on-call twenty-four (24) hours per day during the Delivery Term. The Facility shall be operated during the Delivery Term by an Affiliate of Seller, by the party listed on Appendix N or such other Person as Buyer shall approve in the exercise of its reasonable discretion. For the avoidance of doubt, in no event will the operation of the Facility by a third party, nor shall Buyer’s approval of any third party operator, relieve Seller of any of its obligations hereunder.

Section 5.3 Operation and Maintenance Plan. Seller shall devise and implement a plan of inspection, maintenance, and repair for the Facility and the components thereof in order to maintain such equipment in accordance with Prudent Utility Practices, and shall keep records with respect to inspections, maintenance, and repairs thereto. The aforementioned plan and all records of such activities shall be available for inspection by Buyer during Seller’s regular business hours upon reasonable notice.

Section 5.4 Taxes. Commencing on the Prepayment Date, Buyer will be responsible for, and will reimburse Seller if paid by Seller, lawful state and local taxes assessed within the State of Utah, which are directly associated with the Facility or the delivery or sale of Energy or Environmental Attributes, if any, including all property taxes or payments in lieu of property taxes directly associated with the Facility and excluding income, payroll, and sales taxes (other

than sales taxes directly imposed on the delivery or sale of Energy or Environmental Attributes, if any) (“Taxes”). To the extent reasonably able to do so, either Party, upon written request of the other, shall provide a certificate of exemption or other reasonably satisfactory evidence of exemption if either Party is exempt from any Taxes, and shall use all reasonable efforts to obtain or maintain, or to enable the other Party to obtain or maintain, any exemption from or reduction of any Taxes, whether currently available or becoming available in the future. Seller will pay all lawful Taxes and will use reasonable efforts to minimize Taxes, and will consult with Buyer on any negotiations Seller may undertake with governmental authorities responsible for imposing Taxes. Promptly following its payment of any Taxes, Seller shall provide Buyer with copies of receipts or other evidence of the payment of such Taxes. Seller shall also promptly provide to Buyer copies of all notices, correspondence or other items (including, without limitation, written reports on any verbal exchanges with the relevant taxing authorities) to the extent relating to Taxes, and shall afford Buyer a reasonable opportunity to participate in any discussions or other communications with any taxing authority relating to Taxes. To the extent it is legally able to do so, Seller will follow the written instructions of Buyer with respect to the negotiation, reporting, payment and contest (and shall permit Buyer to conduct such contest, to the extent it is legally able to do so) of any Taxes for which Seller is liable hereunder. Seller shall promptly pay to Buyer the amount of any refunds or other credits against any Taxes or other economic benefits which Seller receives or to which it is entitled with respect to any Taxes for which Buyer is responsible hereunder. Without limiting the generality of the foregoing, the Parties agree that, if beneficial to the efforts of either Party to obtain or maintain any exemption from or reduction of any Taxes, whether currently available or becoming available in the future, the Parties will cooperate to restructure the transactions contemplated by this Agreement so as to enable either Party to obtain or maintain such exemption or reduction, as the case may be, provided, however, that any such restructuring shall not affect adversely the economic consequences to either Party. Buyer shall have no obligations with to respect to any Taxes to the extent such Taxes (1) are attributable to any period prior to the Commercial Operation Date, or following the expiration or termination of this Agreement in accordance with the terms hereof, (2) are imposed as a result of the gross negligence or willful misconduct by the Seller, the breach by the Seller of any of its obligations under this Agreement, any Ancillary Document or any related transaction document, (3) are imposed as a result of any transfers by Seller of any interest in the Facility, this Agreement or any transaction contemplated hereby or related hereto (except to the extent resulting from a breach by Buyer if its obligations under this Agreement).

Section 5.5 Environmental Credits. Seller shall, if applicable, obtain in its own name and at its own expense any and all pollution or environmental credits or offsets necessary to operate the Facility in compliance with the Requirements of Law.

Section 5.6 Scheduling of Energy and Scheduled Outages. The Authorized Representatives of the Buyer and Seller shall, as soon as reasonably practicable following the Effective Date, and in any event prior to the Commercial Operation Date, mutually develop forecasting and Scheduling procedures which may be modified, from time to time, by written agreement of both Authorized Representatives in order to comply with all applicable requirements, including those of the Transmission Provider, CAISO, WECC, and any balancing authority. The Authorized Representatives shall promptly cooperate with respect to any reasonably necessary and appropriate modifications to such forecasting or scheduling procedures.

(a) Seller or Seller’s designee shall be responsible for Scheduling the forecast of Energy to the Point of Delivery during the Delivery Term in accordance with the dispatch and Scheduling procedures that may be updated from time to time by Buyer or Buyer’s Agent. Seller shall submit schedules, and any updates to such schedules, to Buyer or Buyer’s Agent designated by Buyer based on the most current forecast of Energy. All generation scheduling and Transmission Services shall be performed in accordance with the applicable NERC, CAISO, and WECC operating policies, criteria, and any other applicable guidelines. Seller shall also fulfill the contractual, metering and interconnection requirements set forth in this Agreement, so as to be able to deliver Energy to the Point of Delivery.

(b) Following the Commercial Operation Date, no later than forty-five (45) days before the beginning of each calendar year, Seller or Seller’s designee shall provide, or cause to be provided, a non-binding forecast of each month’s average-day deliveries of Energy, by hour, for the following eighteen (18) months.

(c) Following the Commercial Operation Date, ten (10) Business Days before the beginning of each month, Seller or Seller’s designee shall provide, or cause to be provided, a non-binding forecast of each day’s average deliveries of Energy, by hour, for the following month.

(d) Following the Commercial Operation Date, Seller or Seller’s designee shall cause the Facility’s Scheduling coordinator to provide Buyer, Buyer’s Agent, Buyer’s real time operators, and Buyers designated Scheduling representatives:

(1) by 5:30 AM Pacific Prevailing Time on the Business Day immediately preceding the date of delivery of Energy, with a copy of a non-binding hourly forecast of deliveries of Energy for each hour of the immediately succeeding day. Any forecast provided a day prior to any non-Business Day shall include a forecast for that non-Business Day, each succeeding non-Business Day, and the next Business Day. Seller shall provide Buyer, or Buyer’s Agent, with a copy of any and all updates to such forecast indicating a change in forecasted Energy from the then-current forecast. Daily and hourly scheduling with the CAISO and the WECC shall be performed in accordance with Scheduling procedures mutually agreed upon by Buyer and the applicable Scheduling representatives of Seller prior to the date on which Seller anticipates to commence the delivery of Start-up and Test Energy.

(2) by 12:00 p.m. on the normal Business Day prior to each pre-scheduling day as identified in the WECC prescheduling calendar, via email, with day-ahead pre-schedules for each of the succeeding twenty-four (24) hours in the form of an excel spreadsheet. In order to allow Buyer to make schedule changes in conformity with the CAISO Scheduling deadline, Seller shall notify Buyer or Buyer’s Agent via telephone of any hourly changes due to a change in unit availability or an outage no later than one-hundred five (105) minutes (one (1) hour and forty-five (45) minutes) prior to the start of such scheduling hour. Seller shall follow up with Buyer via email within thirty (30) minutes of placing the telephone call in order to confirm the hourly change and to provide Buyer with an explanation for the change; and

(3) with continuously updated non-binding hourly forecasts of deliveries of Energy for each hour of the succeeding twenty (24)-hour period, in either electronic format, via an internet website accessible to Buyer, Buyer’s Agent, Buyer’s real time operators, and Buyers designated Scheduling representatives, or via email in the form of an excel spreadsheet (or any combination thereof), transmitted on an hourly basis. Seller shall attempt to optimize the estimates for such time period two (2) hours prior to such forecasts.

(e) Following the Commercial Operation Date, Buyer and Seller shall cooperate to minimize Scheduled Outages during certain consecutive or nonconsecutive weeks of each Contract Year (not to exceed twelve (12) weeks per Contract Year) specified by Buyer (the “Major Maintenance Blockout”), but in accordance with Prudent Utility Practices. No later than one hundred twenty (120) days prior to the Commercial Operation Date and the commencement of each Contract Year thereafter, Buyer shall provide Seller with its specified Major Maintenance Blockout. Seller shall attempt to minimize its Scheduled Outages during the Major Maintenance Blockout consistent with Prudent Utility Practices. No later than sixty (60) days prior to the Commercial Operation Date, and on each January 1 thereafter, Seller shall provide Buyer, or Buyer’s Agent as designated by Buyer, with a non-binding written projection of all Scheduled Outages for the succeeding three (3) years (the “Scheduled Outage Projection”), reflecting a minimized schedule of scheduled maintenance during the Major Maintenance Blockout. In addition, Seller shall cooperate in good faith with Buyer’s maintenance scheduling requests consistent with Prudent Utility Practices. The Scheduled Outage Projection shall include information concerning all projected Scheduled Outages during such period, including (i) the anticipated start and end dates of each Scheduled Outage; (ii) a description of the maintenance and/or repair work to be performed during the Scheduled Outage; and (iii) the anticipated MW capacity, if any, during the Scheduled Outage. Seller shall notify Buyer, or Buyer’s Agent, of any change in the Scheduled Outage Projection as soon as practicable, but in no event later than thirty (30) days prior to the originally scheduled date of the Scheduled Outage. Seller will use commercially reasonable efforts to accommodate reasonable requests of Buyer with respect to the timing of Scheduled Outages and Seller will, to the extent feasible and consistent with Prudent Utility Practices, and except when such Scheduled Outages would overlap with the Major Maintenance Blockout, arrange for Scheduled Outages to occur between October 1 and May 1 of each year and coincident with planned transmission outages. In the event of a System Emergency, Seller shall make all reasonable efforts to reschedule any Scheduled Outage previously scheduled to occur during the System Emergency.

(f) In the event of a Forced Outage affecting at least ten percent (10%) of the installed capacity of the Facility, to the extent practicable, Seller shall notify Buyer, or Buyer’s Agent, within two (2) hours of the Forced Outage and provide detailed information concerning the Forced Outage, including (i) the start and anticipated end dates of the Forced Outage; (ii) a description of the cause of the Forced Outage; (iii) a description of the maintenance and/or repair work to be performed during the Forced Outage; and (iv) the anticipated MW capacity, if any, during the Forced Outage. Seller shall take all reasonable measures and exercise commercially reasonable efforts to avoid Forced Outages and to limit the duration and extent of any such outages.

(g) Seller shall reduce deliveries of Energy for curtailments required by Buyer (i) due to a System Emergency, (other than due to a Force Majeure event as set forth in (iii) below), (ii) due to system improvements, curtailments and/or scheduled and unscheduled repairs or maintenance on Buyer’s side of the Point of Delivery, (other than due a Force Majeure event as set forth in (iii) below) that prevent it from accepting Energy at the Point of Delivery, or (iii) due to an event of Force Majeure on Buyer’s side of the Point of Delivery, that prevents it from accepting Energy at the Point of Delivery, or (iv) after December 31, 2010, if the STS Upgrade has not been completed and the Interim Energy exceeds the Maximum Interim Energy Amount. Seller shall provide the capability to implement curtailments and adjust curtailment amounts in real-time by means of setpoints received from the supervisory control and data acquisition (“SCADA”) system of Buyer or Buyer’s Agent. During the Agreement Term, the Parties shall reasonably estimate the amount of such curtailed Energy and Seller shall be credited for all curtailed Energy under subsections (i) and (ii) of this Section 5.6(g) that would have been realized had the curtailment not occurred in accordance with this Section 5.6(g); and for the avoidance of doubt, Seller shall not be credited for Energy that was curtailed under subsection (iii) of this Section 5.6(g). Curtailed Energy under subsections (i) and (ii) of this Section 5.6(g) in any Contract Year shall be deemed Delivered Energy for purposes of determining Delivered Guaranteed Generation until the Guaranteed Annual Quantity for such Contract Year has been achieved (“Deemed Delivered Prepaid Energy”) and thereafter, for such Contract Year, shall be deemed Delivered Excess Energy (“Deemed Delivered Excess Energy”). Curtailed Energy under Subsections (i) and (ii) of this Section 5.6(g) prior to the Commercial Operation Date shall be deemed delivered Startup and Test Energy (“Deemed Delivered Startup and Test Energy”) and, following the Commercial Operation Date and prior to the Prepayment Date curtailed Interim Energy under Subsections (i), (ii) and (iv) shall be deemed delivered Interim Energy (“Deemed Delivered Interim Energy”), as applicable. For the avoidance of doubt, the Parties agree that: (1) prior to the earlier of the completion of the STS Upgrade or December 31, 2010, Seller shall not deliver Interim Energy in an amount that exceeds the Maximum Interim Energy Amount, and (2) for the period between December 31, 2010, and the Prepayment Date, if any Interim Energy is curtailed pursuant to subsection (iv), such curtailed Energy shall be Deemed Delivered Interim Energy. Subject to this Section, Buyer shall pay Seller for such Deemed Delivered Excess Energy, at the Excess Energy Price then in effect, for such Deemed Delivered Startup and Test Energy at the price for Startup and Test Energy set forth in Appendix A, and for such Deemed Delivered Interim Energy at the Interim Energy Rate. During any period of curtailment under subsections (i), (ii) or (iv) of this Section 5.6(g), Seller shall use reasonable commercial efforts to sell such curtailed Energy (but not the Environmental Attributes associated with such curtailed Energy) to third parties; provided that (A) Seller shall remit to Buyer any net proceeds resulting from the sale of Deemed Delivered Prepaid Energy and such proceeds shall be the property of Buyer, (B) if such Energy is sold to third parties, Seller shall deliver the Environmental Attributes to Buyer and Buyer shall pay Seller for such Environmental Attributes in accordance with Section 12.1(a)(5); and (C) any proceeds from the sale of Deemed Delivered Excess Energy, Deemed Delivered Startup and Test Energy or Deemed Delivered Interim Energy to a third party purchaser shall be the property of Seller and Buyer shall have no obligation to pay Seller for such Deemed Delivered Excess Energy, Deemed Delivered Startup and Test Energy or Deemed Delivered Interim Energy. For the avoidance of doubt, the provisions of this Section 5.6(g) shall not apply to curtailments resulting from a Force Majeure event preventing Seller from delivering Energy from the Facility as described in Section 15.6(a).

Seller shall install sufficient measuring equipment at the Facility to collect data necessary to reasonably determine the amount of Deemed Delivered Prepaid Energy, Deemed Delivered Excess Energy, Deemed Delivered Startup and Test Energy or Deemed Delivered Interim Energy. Seller shall install sufficient meteorological towers around the Facility Generating Premises or in conjunction with the wind turbines comprising the Facility to provide the capability of measuring and recording representative wind data twenty-four (24) hours per day, which wind data, in conjunction with actual wind turbine availability and capability, shall be used to calculate the Deemed Delivered Prepaid Energy, Deemed Delivered Excess Energy, Deemed Delivered Startup and Test Energy and Deemed Delivered Interim Energy.

ENVIRONMENTAL ATTRIBUTES; EPS AND RPS COMPLIANCE

Section 9.1 Transfer of Environmental Attributes. For and in consideration of Buyer entering into this Agreement, and in addition to the agreement by Buyer and Seller to purchase and sell Energy on the terms and conditions set forth herein, Seller shall transfer to Buyer, and Buyer shall receive from Seller, all right, title, and interest in and to all Environmental Attributes, free and clear of all Liens, whether now existing or acquired by Seller or that hereafter come into existence or are acquired by Seller during the Agreement Term, for all Delivered Energy and Replacement Energy. Seller agrees to transfer and make such Environmental Attributes available to Buyer immediately to the fullest extent allowed by applicable law upon Seller’s production or acquisition of such Environmental Attributes. Seller represents and covenants that it has not assigned, transferred, conveyed, encumbered, sold or otherwise disposed of (other than Liens on the proceeds of the Environmental Attributes in favor of Facility Lender) and will not in the future assign, transfer, convey, encumber, sell or otherwise dispose of all or any portion of such Environmental Attributes to any Person other than Buyer or attempt to do any of the foregoing with respect to any of the Environmental Attributes.

Section 9.2 Reporting of Ownership of Environmental Attributes. During the Agreement Term, Seller shall not report to any Person that the Environmental Attributes granted hereunder to Buyer belong to any Person other than Buyer, and Buyer may report under any program that such Environmental Attributes purchased hereunder belong to it.

In furtherance and not in limitation of Section 9.3, Seller shall use WREGIS or any successor system to evidence the transfer of any Environmental Attributes considered RECs under applicable law or any voluntary program (“WREGIS Certificates”), associated with Facility Energy or Replacement Energy in accordance with WREGIS reporting protocols, and as such shall register the Facility with WREGIS. After the Facility is registered with WREGIS, at Buyer’s option, Seller shall (i) transfer WREGIS Certificates using the Forward Certificate Transfer method, as described in WREGIS Operating Rules, from Seller’s WREGIS account to up to three WREGIS accounts, as designated by Buyer, or (ii) retire said WREGIS Certificates into Seller’s WREGIS Retirement sub-account on behalf of Seller’s requirements (if any); provided, however, that Seller must initially select to use either option (i) or (ii) thirty (30) days prior to delivering any Energy to the Point of Delivery, and, provided, further, if option (i) is selected, Buyer may change to option (ii) at the beginning of any calendar year during the Agreement Term upon thirty (30) days advance written notice. If option (ii) is selected, then Buyer shall provide Seller the number and vintage of MWh of WREGIS Certificates to be retired by providing written notice to Seller not later than thirty (30) days prior to the desired retirement date. Seller shall be responsible for the WREGIS expenses associated with registering the Facility, maintaining its account, WREGIS Certificate issuance fees, and transferring WREGIS Certificates to Buyer or Buyer’s Agent, or any other designees, and Buyer shall be responsible for the WREGIS expenses associated with maintaining its account, or the accounts of its designees, if any, and subsequent transferring or retiring of WREGIS Certificates, or Seller’s fees for the retirement of WREGIS Certificates on behalf of Buyer. Forward Certificate Transfers will occur monthly based on the certificate creation time-line established by the WREGIS Operating Rules. As of the Effective Date, the certificate creation time line is established as not later than ninety (90) days following the end of each month. For example, for MWhs generated in January 2010, the certificates will be created in WREGIS not later than April 30, 2010. Seller shall be responsible for, at its expense, validating and disputing data with WREGIS prior to certificate creation each month. In the event that WREGIS is not in operation, or WREGIS does not track Seller’s transfer of WREGIS Certificates to Buyer, Buyer’s Agent, or its designees for purposes of any RECs attributed, accrued, realized, generated, produced, recognized or validated relative to the Facility Energy or Replacement Energy, or Buyer chooses not to use WREGIS for any reason, Seller shall document the production and transfer of RECs under this Agreement by delivering to Buyer an attestation for the RECs produced by the Facility, or Replacement Energy, measured in whole MWh, or by such other method as Buyer shall designate.

Section 9.5 Further Assurances. If such function is not already accomplished via WREGIS, Seller will document the production of Environmental Attributes by delivering with each invoice to Buyer an attestation for Environmental Attributes (i) produced by the Facility or (ii) included with Replacement Energy for the preceding calendar month. The form of attestation is set forth as Appendix D. At Buyer’s request, the Parties shall execute all such documents and instruments and take such other action in order to effect the transfer of the Environmental Attributes specified in this Agreement to Buyer’s Agents as Buyer may reasonably request. In the event of the promulgation of a scheme involving Environmental Attributes administered by CAMD, upon notification by CAMD that any transfers contemplated by this Agreement will not be recorded, the Parties shall promptly cooperate in taking all

reasonable actions necessary so that such transfer can be recorded. Each Party shall promptly give the other Party copies of all documents it submits to CAMD to effectuate any transfers.

Section 9.6 RPS and EPS Compliance. Seller warrants and guarantees that when complete, the Facility will be both RPS Compliant and, if required by applicable Requirements of Law, EPS Compliant. From time to time and at any time requested by Buyer, Seller will furnish to Buyer or Governmental Authorities or other Persons designated by Buyer, all certificates and other documentation reasonably requested by Buyer in order to assist Buyer in qualifying the Facility as RPS Compliant and EPS Compliant, if required by applicable Requirements of Law.

In addition, Seller and its Major Subcontractors shall also include the following language in each Subcontractor contract: “The Southern California Public Power Authority is a third party beneficiary of the foregoing audit provision. The benefits of the audit provision shall inure solely for the benefit of the Southern California Public Power Authority. The designation of the Southern California Public Power Authority as a third party beneficiary of the audit provision shall not confer any rights or privileges on Seller, subcontractor or any other person/entity.” Notwithstanding the foregoing, if the audit reveals that Buyer overpayment to Seller is more than five percent (5.0%) of the billings reviewed, Seller shall pay all expenses and costs incurred by the Authorized Auditors arising out of or related to the examination or audit. Such examination or audit expenses and costs shall be paid by Seller to Buyer within thirty (30) calendar days of notice to Seller of such costs and expenses.

(b) Notwithstanding anything herein to the contrary, this Section shall not be deemed to require that Buyer pay for any costs and expenses of Seller other than the Taxes and Operating Insurance premiums as required under this Agreement.

Section 12.5 Electric Metering Devices.

(a) The Facility Energy made available to Buyer, or Buyer’s Agent, by Seller under this Agreement shall be measured using Electric Metering Devices installed, owned and maintained by Seller or its designee in accordance with the Interconnection Agreement, if applicable, and Prudent Utility Practices. Such Electric Metering Devices shall be installed (i) at the Site Common Facilities Substation located on the Facility Generating Premises; and (ii) at the Point of Delivery. All Electric Metering Devices used to provide data for the computation of payments shall be sealed and the Seller or its designee shall only break the seal when such Electric Metering Devices are to be inspected and tested or adjusted in accordance with this

Section 12.5. Seller or its designee shall specify the number, type, and location of such Electric Metering Devices subject to the requirements of Section 12.5(b).

(b) Although the Facility shares a common Point of Delivery with the Milford Wind Phase I Facility, the two facilities have separate scheduling, operating, and energy accounting requirements, and therefore require metering arrangements that will permit separate calculations for the Facility and for Milford Wind Phase I Facility. Appendix Q sets forth the procedure for separate calculations.

(1) The Electric Metering Devices installed at the Site Common Facilities Substation located on the Facility Generating Premises shall include but not be limited to revenue-quality measurements of the Facility’s instantaneous MW, instantaneous MVAR, MWh received, MWh delivered, MVARh received, and MVARh delivered.

(2) The Electric Metering Devices for the Facility’s MWh received, MWh delivered, MVARh received, and MVARh delivered shall be capable of receiving and executing an accumulator freeze request from the SCADA system of the Buyer or Buyer’s agent, as do the existing electric metering devices installed at the Point of Delivery for measuring Energy delivered from the Milford Wind Phase I Facility. The accumulator freeze request will be provided by means of the Distributed Network Protocol version 3 (DNP 3). The accumulator freeze request shall be delivered to the aforementioned Electric Metering Devices within five (5) seconds of the time that the accumulator freeze request is available at Seller’s Facility.

(3) Delivered Energy that is metered shall be the Energy as measured by the Electric Metering Devices described in this Section 12.5(b) and allocated according to Appendix Q. All meters used in the calculations shown in Appendix Q shall meet the requirements of this Section 12.5(b).

(c) Seller or its designee, at no expense to Buyer, shall inspect and test all Electric Metering Devices upon installation and at least annually thereafter. Seller shall provide Buyer with reasonable advance notice of, and permit a representative of Buyer to witness and verify, such inspections and tests, provided, however, that Buyer shall not unreasonably interfere with or disrupt the activities of Seller or its designee and shall comply with all safety standards applicable to the Facility Premises as provided to Buyer by Seller in writing. Upon request by Buyer, Seller or its designee shall perform additional inspections or tests of any Electric Metering Device and shall permit a qualified representative of Buyer to inspect or witness the testing of any Electric Metering Device; provided, however, that Buyer shall not unreasonably interfere with or disrupt the activities of Seller or its designee and shall comply with all safety standards applicable to the Facility Premises as provided to Buyer by Seller in writing. The actual expense of any such requested additional inspection or testing shall be borne by Seller.

(d) Adjustment for Inaccurate Meters. If an Electric Metering Device fails to register, or if the measurement made by an Electric Metering Device is found upon testing to be inaccurate by more than one percent (1.0%), an adjustment shall be made correcting all

measurements by the inaccurate or defective Electric Metering Device for both the amount of the inaccuracy and the period of the inaccuracy. The adjustment period shall be determined by reference to Seller’s check-meters, if any, or as far as can be reasonably ascertained by Seller from the best available data, subject to review and approval by Buyer. If the period of the inaccuracy cannot be ascertained reasonably, any such adjustment shall be for a period equal to one-third of the time elapsed since the preceding test of the Electric Metering Devices. To the extent that the adjustment period covers a period of deliveries for which payment has already been made by Buyer, Seller shall use the corrected measurements as determined in accordance with this Section 12.5 to recompute the amount due for the period of the inaccuracy and shall subtract the previous payments by Buyer for this period from such recomputed amount. If the difference is a positive number, the difference shall be paid by Buyer to Seller; if the difference is a negative number, that difference shall be paid by Seller to Buyer, or at the discretion of Buyer, may take the form of an offset to payments due to Seller from Buyer. Payment of such difference by the owing Party shall be made not later than thirty (30) days after the owing Party receives notice of the amount due, unless Buyer elects payment via an offset.

Section 14.2 Default Remedy.

(a) If Buyer is in Default for nonpayment, subject to any duty or obligation under this Agreement, Seller may, at its sole option, suspend service, sell Energy and Environmental Attributes to third parties pursuant to and in accordance with Section 7.4 or continue to provide services pursuant to its obligations under this Agreement; provided that nothing in this Section 14.2(a) shall affect Seller’s rights and remedies set forth in this Section 14.2; and provided, further, that Excess Energy sold to third parties shall not count toward Delivered Guaranteed Generation. Seller’s continued service to Buyer shall not act to relieve Buyer of any of its duties or obligations under this Agreement.

(b) Notwithstanding any other provision herein, if any Default has occurred and is continuing, the affected Party may, whether or not the dispute resolution procedure set forth in Section 15.3 has been invoked or completed, bring an action in any court of competent jurisdiction as required by Section 15.3 seeking injunctive relief in accordance with applicable California or Federal rules of civil procedure.

(c) Except as expressly limited by this Agreement, if a Default has occurred and is continuing and Buyer is the Defaulting Party, Seller may without further notice exercise any rights and remedies provided herein or otherwise available at law or in equity, including the right to terminate this Agreement upon giving notice of intent to terminate to Buyer. No failure of Seller to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by Seller of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power.

(d) Except as expressly limited by this Agreement, if a Default has occurred and is continuing and Seller is the Defaulting Party, Buyer may without further notice exercise any rights and remedies provided for herein, or otherwise available at law or equity, including (i) application of all amounts available under the LD Security, Performance Security, and the Deed of Trust against any amounts then payable by Seller to Buyer under this Agreement, (ii) termination of this Agreement pursuant to Section 14.4, (iii) exercise its rights under the Deed of Trust, subject to the provisions of this Agreement, and (iv) foreclosure of Buyer’s Deed of Trust, upon notice of intent to terminate this Agreement to Seller.

Section 14.3 Effect of Termination on Interconnection Agreement. The expiration or termination for any reason of this Agreement shall not affect the Leases and Property Agreements or the Interconnection Agreement or the continuing effectiveness thereof.

Section 14.4 Termination for Default.

(a) If Default occurs, the Party that is not the Defaulting Party (the “Non Defaulting Party”) shall, for so long as the Default is continuing, and subject to applicable cure rights, and without limiting any other rights or remedies available to the Non-Defaulting Party under this Agreement, possess the right to terminate this Agreement upon written notice to the Defaulting Party in accordance with Section 15.2, such notice of termination shall specify the date on which the termination is to become effective.

(b) Upon termination, the Non Defaulting Party shall liquidate this Agreement as soon as practicable. The Termination Payment shall be calculated in accordance with Section 14.5. With respect to Seller, the Termination Payment shall be the sole and exclusive remedy for termination of this Agreement after the termination under this Section 14.4 is received.

(c) Upon termination, the Non-Defaulting Party may withhold any payments it owes the Defaulting Party for any obligations incurred prior to termination under this Agreement until the Defaulting Party pays the Termination Payment to the Non Defaulting Party. The Non Defaulting Party shall possess the right to set off the amount due it under this Section 14.4 by any such payments due the Defaulting Party.

Section 14.5 Calculation of Termination Payment. The Non Defaulting Party shall calculate the Termination Payment as follows:

(a) If Seller is the Defaulting Party, upon any termination under Section 14.4, Seller shall pay Buyer the Remaining Prepayment Amount. In addition to such payment of the Remaining Prepayment Amount, Buyer shall calculate the Gains, Losses, and Costs. The Gains, Losses, and Costs shall include those for the Excess Energy and the Environmental Attributes, which shall be determined by comparing (i) the value of the Excess Energy and Environmental Attributes projected to be delivered for the remaining term giving effect to the Excess Energy Price and the value derived from the Environmental Attributes under this Agreement had it not been terminated to (ii) the equivalent quantities and relevant market prices for the remaining term either quoted by a bona fide third party offer or which are reasonably expected to be available in the market under a replacement contract for this Agreement. To ascertain the market prices of a replacement contract, Buyer may consider, among other valuations, quotations from dealers in energy contracts and bona fide third party offers, all adjusted for the length of the remaining term and differences in transmission. It is expressly agreed that Buyer shall not be required to enter into replacement transactions in order to determine the Termination Payment.

(b) If Buyer is the Defaulting Party, upon any termination under Section 14.4, Seller shall pay Buyer the Remaining Prepayment Amount, unless offset by termination payments otherwise due to Seller. In addition to such obligation for payment of the Remaining

Prepayment Amount, Seller shall calculate the Gains, Losses and Costs. The Gains, Losses, and Costs shall include those for the Excess Energy and the Environmental Attributes, which shall be determined by comparing the value of the Excess Energy and Environmental Attributes projected to be delivered for the remaining Delivery Term giving effect to the Excess Energy Price and the value derived from the Environmental Attributes under this Agreement had it not been terminated to the equivalent quantities and relevant market prices for the remaining Delivery Term either quoted by a bona fide third party offer or which are reasonably expected to be available in the market under a replacement contract for this Agreement. To ascertain the market prices of a replacement contract, Seller may consider, among other valuations, quotations from dealers in energy contracts and bona fide third party offers, all adjusted for the length of the remaining Delivery Term and differences in transmission. It is expressly agreed that Seller shall not be required to enter into replacement transactions in order to determine the Termination Payment.

(c) The Gains and Losses for Excess Energy and Environmental Attributes calculated under Section 14.5(a) shall be discounted to present value using the Present Value Rate as of the time of termination (to take account of the period between the time notice of termination was effective and when such amount would have otherwise been due if this Agreement had been performed in full).

(d) Each Party shall use reasonable efforts to mitigate or eliminate Costs.

(e) In no event, however, shall a Party’s Gains, Losses or Costs include any penalties or similar charges imposed by the Non-Defaulting Party.

(f) The Non Defaulting Party shall set off or aggregate, as appropriate, the Gains and Losses and Costs and notify the Defaulting Party. If the Non Defaulting Party’s aggregate Losses and Costs exceed its aggregate Gains with respect to Excess Energy and Environmental Attributes, the Defaulting Party shall, within three (3) Business Days of receipt of such notice, pay the resulting Termination Payment, after any aggregation or set off as provided in Section 14.5(g), to the Non Defaulting Party, which amount shall bear interest at the Present Value Rate from the time notice of termination was received until paid. If the Non Defaulting Party’s aggregate Gains exceed its aggregate Losses and Costs, the Termination Payment shall be zero.

(g) The Non Defaulting Party shall aggregate or set off, as applicable, at its election, any or all other amounts owing between the Parties under this Agreement with or against the Termination Payment so that all such amounts are aggregated and/or netted to a single liquidated amount, which shall be the amount of the Termination Payment. Such Termination Payment shall be paid within three (3) Business Days following the date notice of termination is received. Notwithstanding any other provision of this Section 14.5, if Buyer shall be the Non-Defaulting Party, in no event shall the amount of the Termination Payment due Buyer be less than the Remaining Prepayment Amount, subject, however, to aggregation or setoff, as applicable, of any amounts owing between the Parties under this Agreement other than Gains, Losses and Costs.

(h) If the Defaulting Party disagrees with the calculation of the Termination Payment and the Parties cannot otherwise resolve their differences, the calculation issue shall be submitted to informal dispute resolution as provided in Section 15.3(a). Pending resolution of the dispute, the Defaulting Party shall pay the full amount of the Termination Payment calculated by the Non Defaulting Party within three (3) Business Days of receipt of notice of termination as set forth in Section 14.4(a) subject to the Non Defaulting Party refunding, with interest, at the Present Value Rate, any amounts determined to have been overpaid.

(i) For purposes of this Section 14.5:

(1) “Gains” means the economic benefit (exclusive of Costs), if any, resulting from the termination of this Agreement, determined in a commercially reasonable manner, as calculated in accordance with this Section 14.5;

(2) “Losses” means the economic loss (exclusive of Costs), if any, resulting from the termination of this Agreement, determined in a commercially reasonable manner as calculated in accordance with this Section 14.5;

(3) “Costs” means brokerage fees, commissions and other similar transaction costs and expenses reasonably incurred in terminating any specifically related arrangements or entering into arrangements which replace this Agreement, and excluding attorneys’ fees, if any, incurred in connection with the Non Defaulting Party enforcing its rights with regard to this Agreement.

(c) In the event a Dispute is not resolved pursuant to the procedures set forth in Section 15.3(a) and Section 15.3(b) by the expiration of the thirty (30) day period set forth in Section 15.3(a) then either Party may pursue any legal remedy available to it in accordance with the provisions of Section 15.12 of this Agreement.

(d) Claims Presentment Under California Law. As stated in Section 15.12, this Agreement shall be governed by, interpreted and enforced in accordance with the laws of the State of California, without regard to the conflict of laws principles thereof. In addition to the dispute resolution process set forth in this Section, the Parties to this Agreement must comply with California law governing claims against public entities and presentment of such claims.

Section 15.4 Further Assurances. Each Party agrees to execute and deliver all further instruments and documents, and take all further action not inconsistent with the provisions of this Agreement that may be reasonably necessary to effectuate the purposes and intent of this Agreement.

Section 15.5 No Dedication of Facilities. Any undertaking by one Party hereto to the other Party under any provisions of this Agreement shall not constitute the dedication of the system or any portion thereof of either Party to the public or to the other Party or any other Person, and it is understood and agreed that any such undertaking by either Party shall cease upon the termination of such Party’s obligations under this Agreement.

Section 15.6 Force Majeure.

(a) A Party shall not be considered to be in default in the performance of any of its obligations under this Agreement (other than the obligations of a Party to make payment of amounts due under this Agreement), including Buyer’s obligations to receive Energy (including Startup or Test Energy, Interim Energy, Guaranteed Generation, Excess Energy and Shortfall Energy) at the Point of Delivery, when and to the extent such Party’s performance is prevented by a Force Majeure that, despite the exercise of due diligence, such Party is unable to prevent or mitigate; provided the Party has given a written detailed description of the full particulars of the Force Majeure to the other Party reasonably promptly after becoming aware thereof (and in any event within fourteen (14) days after the initial occurrence of the claimed Force Majeure) (the “Force Majeure Notice”), which notice shall include information with respect to the nature, cause and date and time of commencement of such event, and the anticipated scope and duration of the delay. The Party providing such notice shall be excused from fulfilling its obligations under this Agreement until such time as the Force Majeure has ceased to prevent performance or other remedial action is taken, at which time the Party shall promptly notify the other Party of the resumption of its obligations under this Agreement. Notwithstanding anything in this Agreement to the contrary, if Seller is unable to deliver or Buyer is unable to receive Excess Energy due to a Force Majeure, Buyer shall have no obligation to pay Seller for the Excess Energy not delivered or received by reason thereof. It is understood by the Parties that the foregoing provisions shall not excuse any obligations of Seller with respect to delivery of the Guaranteed Generation under Article VII, or Shortfall Energy and Replacement Energy provided under Article X, or Buyer’s obligation to make Monthly Payments up to the time that Seller ceases deliveries of Energy due to Force Majeure. In no event shall Buyer be obligated to compensate Seller or any other Person for any losses, expenses or liabilities that Seller or such other Person may sustain as a consequence of any Force Majeure.

(b) The term “Force Majeure” means any act of God, labor disturbance, act of the public enemy, war, insurrection, riot, fire, terrorism, storm or flood, explosion, change in law or any order, regulation or restriction imposed by governmental, military or lawfully established civilian authorities (i) which prevents one Party from performing any of its obligations under this Agreement, (ii) which could not reasonably be anticipated as of the date of this Agreement, (iii) which is not within the reasonable control of, or the result of negligence, willful misconduct, breach of contract, intentional act or omission or wrongdoing on the part of the affected Party (or any subcontractor or Affiliate of that Party, or any Person under the control of that Party or any of its subcontractors or Affiliates, or any Person for whose acts such Affiliate or subcontractor is responsible), and (iv) which by the exercise of due diligence the affected Party is unable to overcome or avoid or cause to be avoided; provided nothing in this clause (iv) shall be construed so as to require either Party to accede or agree to any provision not satisfactory to it in order to settle and terminate a strike or labor dispute in which it may be involved. Any Party rendered unable to fulfill any of its obligations by reason of a Force Majeure shall exercise reasonable efforts to remove such inability with reasonable dispatch within a reasonable time period and mitigate the effects of the Force Majeure. The relief from performance shall be of no greater scope and of no longer duration than is required by the Force Majeure. Without limiting the generality of the foregoing, a Force Majeure does not include any of the following (each an “Unexcused Cause”): (1) any requirement to meet a renewable portfolio standard or any change (whether voluntary or mandatory) in any renewable portfolio

standard that may affect the value of the Energy purchased hereunder; (2) events arising from the failure by Seller to construct, operate or maintain the Facility in accordance with this Agreement, unless such failure was itself caused by an event of Force Majeure; (3) any increase of any kind in any cost; (4) delays in or inability of a Party to obtain financing or other economic hardship of any kind; (5) Seller’s ability to sell any Energy at a price in excess of that provided in this Agreement or Buyer’s ability to purchase any Energy at a price less than those provided in this Agreement; (6) curtailment or other interruption of any Transmission Service unless such curtailment or interruption was itself caused by an event of Force Majeure; failure of third parties to provide goods and services essential to a Party’s performance, unless such failure was itself caused by an event of Force Majeure; (7) Facility or related equipment failure of any kind, including wells, machinery and lines of pipe; or (8) any changes in the financial condition of Buyer, Seller, the Facility Lender or any subcontractor or supplier affecting the affected Party’s ability to perform its obligations under this Agreement.

Section 15.7 Assignment of Agreement.

(a) Except as set forth in this Section 15.7, neither Party hereto shall assign or transfer this Agreement, in whole or in part, or any of its interests hereunder to any other Person without the prior written consent of the other Party hereto. Such consent shall not be unreasonably withheld by either Party. Any attempt to transfer or assign this Agreement, or any privilege hereunder, without such prior written consent, except as provided herein, shall be void and confer no right on any Person that is not a party to this Agreement.

(b) Seller’s consent shall not be required for Buyer to assign this Agreement, in whole or in part; to any of Buyer’s members, provided that at the time of assignment each of the assignees shall have an investment grade rating from Moody’s or Standard & Poor’s.

(c) Buyer’s consent shall not be required for Seller to assign this Agreement to an Affiliate of Seller, subject however to compliance with Section 13.3; provided that Seller provides reasonable assurances and executes documents reasonably required by Buyer regarding Seller’s continued liability for all of Seller’s obligations under this Agreement in the event of any nonperformance on the part of such assignee.

(d) Except as otherwise provided in Buyer’s indenture of trust or similar agreement under which Buyer issues or has issued bonds or other obligations relating to the Facility, it is specifically agreed that there are no third party beneficiaries of this Agreement, and that, except as provided in this Section 15.7, this Agreement shall not grant any rights enforceable by any Person not a party to this Agreement. Notwithstanding the foregoing, Buyer’s consent shall not be required for Seller to collaterally assign this Agreement for the sole purpose of financing this Facility to any Facility Lender; provided, however, that the terms of such financing and the documentation relating thereto shall comply with the applicable terms and conditions of this Agreement. Seller shall provide Buyer with written notice of any such assignment to any Facility Lender no later than thirty (30) days after the assignment. Notwithstanding the foregoing or anything else expressed or implied herein to the contrary, other than liens on the proceeds of the Energy or Environmental Attributes in favor of the Facility Lender, Seller shall not assign, transfer, convey, encumber, sell or otherwise dispose of all or any portion of the Energy, Capacity Rights or Environmental Attributes to any Person.

(e) To facilitate Seller’s obtaining of financing to construct and operate the Facility, Buyer shall provide such consents to assignment or other documents (in form and substance satisfactory to Buyer) as may be reasonably requested by Seller or any Facility Lender in connection with the financing of the Facility, including the acquisition of equity for the development, construction and operation of the Facility; provided, however, that the terms of such financing and the documentation relating thereto shall comply with the applicable terms and conditions of this Agreement. Seller shall reimburse, or shall cause the Facility Lender to reimburse, Buyer for the incremental direct expenses incurred by Buyer in the preparation, negotiation, execution and/or delivery of any documents requested by Seller or the Facility Lender, and provided by Buyer, pursuant to this Section 15.7(e).

(f) In no event shall Buyer be liable to Facility Lender for any claims, losses, expenses or damages whatsoever other than liability Buyer may have to Seller under this Agreement. In the event of any foreclosure, whether judicial or nonjudicial, or any deed in lieu of foreclosure, in connection with any deed of trust, mortgage, or other similar Lien, Facility Lender or other transferee, and their successors in interest and assigns, will be bound by the covenants and agreements of Seller in this Agreement; provided, however, that until the Person who acquires title to the Facility executes and delivers to Buyer a written assumption of Seller’s obligations under this Agreement in form and substance acceptable to Buyer, such Person will not be entitled to any of the benefits of this Agreement. Any sale or transfer of the Facility by Facility Lender must be made only to an entity that is acceptable to Buyer and has financial qualifications and operating experience equivalent to Seller.

(g) Notwithstanding the provision in Section 3.1 as to the ownership of the Facility by Seller during the Agreement Term, Seller may secure its obligations under the Credit Agreement by granting a lien on and security interest in and to the Facility under a deed of trust and related documents which shall include an assignment of Seller’s rights and interests under the Agreement; provided that such deed of trust and related documents shall be subject to, and Seller, Buyer and the Facility Lenders shall enter into and comply with, the terms and provisions of a Consent and Agreement in substantially the form set forth in Appendix O to the Agreement.

(h) Seller may subcontract its duties or obligations under this Agreement without the prior written consent of Buyer, provided, that no such subcontract shall relieve Seller of any of its duties or obligations hereunder.

Section 15.8 Ambiguity. The Parties acknowledge that this Agreement was jointly prepared by them, by and through their respective legal counsel, and any uncertainty or ambiguity existing herein shall not be interpreted against either Party on the basis that the Party drafted the language, but otherwise shall be interpreted according to the application of the rules on interpretation of contracts.

Section 15.11 Entire Agreement. This Agreement (including all Appendices and Exhibits) contains the entire understanding concerning the subject matter herein and supersedes and replaces any prior negotiations, discussions or agreements between the Parties, or any of them, concerning that subject matter, whether written or oral, except as expressly provided for herein. This is a fully integrated document. Each Party acknowledges that no other party, representative or agent, has made any promise, representation or warranty, express or implied, that is not expressly contained in this Agreement that induced the other Party to sign this document. This Agreement may be amended or modified only by an instrument in writing signed by each Party.

Section 15.14 Execution in Counterparts. This Agreement may be executed in counterparts and upon execution by each signatory, each executed counterpart shall have the same force and effect as an original instrument and as if all signatories had signed the same instrument.

Section 15.15 Effect of Section Headings. Section headings appearing in this Agreement are inserted for convenience only and shall not be construed as interpretations of text.

Section 15.16 Waiver. The failure of either Party to this Agreement to enforce or insist upon compliance with or strict performance of any of the terms or conditions hereof, or to take advantage of any of its rights hereunder, shall not constitute a waiver or relinquishment of any such terms, conditions or rights, but the same shall be and remain at all times in full force and effect. Notwithstanding anything expressed or implied herein to the contrary, nothing contained herein shall preclude either Party from pursuing any available remedies for breaches not rising to the level of a Default, including without limitation recovery of damages caused by the breach of this Agreement and specific performance or any other remedy given under this Agreement or now or hereafter existing in law or equity or otherwise. Each Party acknowledges that money damages may not be an adequate remedy for violations of this Agreement and that either Party

may, in its sole discretion, seek and obtain from a court of competent jurisdiction specific performance or injunctive or such other relief as such court may deem just and proper to enforce this Agreement or to prevent any violation hereof. Each Party hereby waives any objection to specific performance or injunctive relief. The rights granted herein are cumulative.

Section 15.17 Relationship of the Parties. This Agreement shall not be interpreted to create an association, joint venture or partnership between the Parties hereto or to impose any partnership obligation or liability upon either such Party.

Section 15.18 Indemnification; Damage or Destruction; Insurance; Limit of Liability.

(a) Indemnification. Seller undertakes and agrees to indemnify and hold harmless Buyer and all of the officers and employees of each, and, at the option of Buyer, defend Buyer, and any and all of its Board, officers, agents, employees, advisors, assigns and successors in interest from and against any and all suits and causes of action, claims, charges, damages, demands, judgments, civil fines and penalties, or losses of any kind or nature whatsoever, for death, bodily injury or personal injury to any person, including Seller’s employees and agents, or damage or destruction to any property of either Party, or third persons in any manner arising by reason of (i) any breach of this Agreement by, or (ii) the negligent acts, errors, omissions or willful misconduct of, in each case under (i) and (ii), Seller, or any of Seller’s officers, agents, employees, or subcontractors of any tier, except to the extent caused by the gross negligence or willful misconduct of Buyer, its Board, officers, agents, or employees.

(b) Damage or Destruction. In the event of any damage or destruction of the Facility or any part thereof, the Facility or such part thereof shall be diligently repaired, replaced or reconstructed by the Seller so that the Facility or such part thereof shall be restored to substantially the same general condition and use as existed prior to such damage or destruction, unless a different condition or use is approved by Buyer. Proceeds of Insurance with respect to such damage or destruction maintained as provided in this Agreement shall be applied, subject to the consent of the Facility Lender, not to be unreasonably withheld, to the payment for such repair, replacement or reconstruction of the damage or destruction.

(d) Condemnation or Other Taking. For the Agreement Term, Seller shall immediately notify Buyer of the institution of any proceeding for the condemnation or other taking of the Facility or any portion thereof. Buyer may participate in any such proceeding and Seller will deliver to Buyer all instruments necessary or required by Buyer to permit such participation. Without Buyer’s prior written consent, Seller (i) shall not agree to any compensation or award, and (ii) shall not take any action or fail to take any action which would cause the compensation to be determined. All awards and compensation for the taking or purchase in lieu of condemnation of the Facility or any portion thereof shall be applied toward the repair, restoration, reconstruction or replacement of the Facility

(e) Limitation of Liability. Except to the extent included in (i) the liquidated damages, (ii) indemnification obligations related to third party claims, and (iii) other specific charges expressly provided for herein, neither Party hereunder shall be liable for special, incidental, exemplary, indirect, punitive or consequential damages arising out of a Party’s performance or non-performance under this Agreement, whether based on or claimed under contract, tort (including such Party’s own negligence) or any other theory at law or in equity. Anything to the contrary in the Agreement notwithstanding, Seller’s maximum liability under the Agreement shall not exceed the Prepayment Amount; provided, however, the foregoing limitation of liability shall not apply to liability arising out of the gross negligence or willful misconduct of Seller or its subcontractors. In addition, to the extent that Buyer receives any insurance proceeds or other payment from a third party with respect to its losses, the amounts received shall not count toward or reduce the liability cap set forth herein.

Section 15.19 Severability. In the event any of the terms, covenants or conditions of this Agreement, or the application of any such terms, covenants or conditions, shall be held invalid, illegal or unenforceable by any court having jurisdiction, all other terms, covenants and conditions of this Agreement and their application not adversely affected thereby shall remain in force and effect, provided that the remaining valid and enforceable provisions materially retain the essence of the Parties’ original bargain.

Section 15.20 Confidentiality.

(a) Each Party agrees, and shall use reasonable efforts to cause its parent, subsidiary and Affiliates, and its and their respective directors, officers, employees and representatives, as a condition to receiving confidential information hereunder, to keep confidential, except as required by law, all documents, data, drawings, studies, projections, plans and other written information that relate to economic benefits to or amounts payable by either Party under this Agreement, and, with respect to documents that are clearly marked “Confidential” at the time a Party shares such information with the other Party (“Confidential Information”). The provisions of this Section 15.20 shall survive and shall continue to be binding upon the Parties for period of one (1) year following the date of termination of this Agreement. Notwithstanding the foregoing, information shall not be considered confidential which (i) is disclosed with the prior written consent of the originating Party, (ii) was in the public domain prior to disclosure or is or becomes publicly known or available other than through the action of the receiving Party in violation of this Agreement, (iii) was lawfully in a Party’s possession or acquired by a Party outside of this Agreement, which acquisition was not known by the receiving Party to be in breach of any confidentiality obligation, or (iv) is developed independently by a Party based solely on information that is not considered confidential under this Agreement .

(b) Either Party may, without violating this Section 15.20, disclose matters that are made confidential by this Agreement:

(1) To its counsel, accountants, auditors, advisors, other professional consultants, credit rating agencies, actual or prospective co-owners, investors, lenders, underwriters, contractors, suppliers, and others involved in construction,

operation, and financing transactions and arrangements for a Party or its subsidiaries, affiliates, or parent;

(2) To governmental officials and parties involved in any proceeding in which either Party is seeking a permit, certificate, or other regulatory approval or order necessary or appropriate to carry out this Agreement; to governmental officials or the public as required by any law, regulation, order, rule, ruling or other Requirement of Law, including without limitation oral questions, discovery requests, subpoenas, civil investigations or similar processes and laws or regulations requiring disclosure of financial information, information material to financial matters, and filing of financial reports. If a Party is requested or required, pursuant to any applicable law, regulation, order, rule, order, ruling or other Requirement of Law, discovery request, subpoena, civil investigation or similar process to disclose any of the Confidential Information, such Party shall provide prompt written notice to the other Party of such request or requirement so that at such other Party’s expense, such other Party can seek a protective order or other appropriate remedy concerning such disclosure.

(c) Notwithstanding the foregoing or any other provision of this Agreement, Seller acknowledges that Buyer, as a California municipal corporation, is subject to disclosure as required by the California Public Records Act, Cal. Govt. Code §§ 6250, et. seq. (“CPRA”), and the Ralph M. Brown Act, Cal. Govt. Code §§ 54950, et. seq. (“Brown Act”). Confidential Information of Seller provided to Buyer pursuant to this Agreement will become the property of Buyer and Seller acknowledges that Buyer shall not be in breach of this Agreement or have any liability whatsoever under this Agreement or otherwise for any claims or causes of action whatsoever resulting from or arising out of Buyer’s copying or releasing to a third party any of the Confidential Information of Seller pursuant to the CPRA or Brown Act. Notwithstanding the foregoing or any other provision of this Agreement, Buyer may record, register, deliver and file all such notices, statements, instruments and other documents as may be necessary or advisable to render fully valid, perfected and enforceable under all applicable law the credit support contemplated by this Agreement and the rights, Liens and priorities of Buyer with respect to such credit support.

(d) If Buyer receives a CPRA request for Confidential Information of Seller, and Buyer determines that such Confidential Information is subject to disclosure under the CPRA, then Buyer will notify the Seller of the request and its intent to disclose the documents. The Buyer, as required by the CPRA, will release such documents unless the Seller timely obtains a court order prohibiting such release. If Seller, at its sole expense, chooses to seek a court order prohibiting the release of Confidential Information pursuant to a CPRA request, then Seller undertakes and agrees to defend, indemnify and hold harmless Buyer from and against all suits, claims, and causes of action brought against Buyer for Buyer’s refusal to disclose Confidential Information of Seller to any person making a request pursuant to CPRA. Seller’s indemnity obligations shall include, but are not limited to, all actual costs incurred by Buyer, and specifically including costs of experts and consultants as well as all damages or liability of any nature whatsoever arising out of any such suits, claims, and causes of action brought against Buyer, through and including any appellate proceedings. Seller’s obligations to Buyer under this indemnification provision shall be due and payable on a monthly, ongoing basis within thirty

(30) days after each submission to Seller of Buyer’s invoices for all fees and costs incurred by Buyer, as well as all damages or liability of any nature.

Section 15.21 Buyer’s Cure Rights and Rights Under Foreclosure.

(a) Buyer Cure Rights Under the Credit Agreement. The provisions of the Credit Agreement which relate to the Buyer’s cure rights and the enforcement thereof shall be in form and substance reasonably acceptable to Buyer and shall provide Buyer with the right, but not the obligation, at any time, to pay any or all amounts due from Seller thereunder and to do any other act or thing required of Seller, in each case to cure any default of Seller thereunder or to prevent the termination of the Credit Agreement or the exercise of any remedy by the Facility Lenders thereunder which would preclude Buyer from exercising its purchase option pursuant to this Section, as contemplated by Section 1.3 of the Consent and Agreement. Under the Credit Agreement the Facility Lenders shall agree not to exercise remedies under the Credit Agreement or any related collateral documents which would preclude Buyer from exercising its purchase option pursuant to this Section, as contemplated by Section 1.3 of the Consent and Agreement until Buyer has been given thirty (30) days from its receipt of notice by the Facility Lenders of the default by Seller to cure a monetary default and, if such default is non-monetary, sixty (60) days from receipt of such notice (or up to ninety (90) days, so long as Buyer is diligently pursuing appropriate action to cure and has made progress toward curing such non-monetary default); and the effect of any such cure by Buyer shall be as if Seller had cured the applicable default within the cure period afforded Seller under the Credit Agreement, including cessation of exercise of remedies by the Facility Lenders. Upon any payment or cure by the Buyer relating to such a default by Seller, the amounts expended by Buyer to provide such cure, including any defaulted payment and interest thereon and all other payments made and expenses incurred by Buyer in providing such cure shall be recovered by Buyer as follows: (i) in the event of the payment of the Prepayment Amount and purchase of Delivered Energy by Buyer, from and after the date of payment of the Prepayment Amount but subject to the provisions with respect to Shortfall Energy under Section 10.1 and Section 10.2, such amounts expended to provide such cure shall be applied in reduction of the Excess Energy Price payable by Buyer for Excess Energy as provided under Section 7.1, or (ii) in the event of the purchase of the Facility by Buyer under this Section, the purchase price shall be reduced by such amounts expended to provide such cure up to a maximum reduction of $2.5 million. For purposes of exercising and enforcing its cure rights as set forth in this Section 15.21 and in the Credit Agreement, Buyer shall be an express third party beneficiary of the applicable provisions under the Credit Agreement. No action of Buyer taken pursuant to the exercise of its rights as provided in this Section 15.21 shall be deemed to be a waiver of any right accruing to Buyer on account of the occurrence of any matter which constitutes a default or a breach of Seller’s obligations under the Agreement.

(b) Foreclosure Under the Credit Agreement. In the event of any default by Seller under the Credit Agreement that has not been cured and upon receipt by Buyer of a Foreclosure Notice (as defined in the Consent and Agreement), Buyer shall have the right, at its option, to purchase the Facility from Seller in lieu of foreclosure as set forth in this Section 15.21. In the event that Buyer furnishes written notice to Seller with a copy to the Facility Lenders within sixty (60) days following Buyer’s receipt of such Foreclosure Notice that it will exercise its option to purchase the Facility and setting forth the date of such purchase (which shall be within ninety (90) days following the date of such Foreclosure Notice), Buyer shall

purchase the Facility from Seller as hereinafter provided. In the case of such purchase of the Facility, Buyer shall furnish Seller with at least fifteen (15) days written notice of the date of purchase and furnish a copy of such notice to the Facility Lenders. The purchase price of the Facility shall be paid by the Buyer to the account designated by the Facility Lenders and shall be equal to the amount of the Facility Debt. Seller agrees and expressly represents and warrants to Buyer that its rights to sell the Facility to Buyer in accordance with the provisions of this Section 15.21 do not and will not conflict with and are permitted by the Credit Agreement and the deed of trust and related agreements and documents securing Seller’s performance under the Credit Agreement.

Section 15.22 LADWP Business Policies. Seller shall use reasonable efforts to comply with the following business policies as applicable hereunder to the extent that Seller is required to do so under California law:

(a) LADWP’s Recycling Policy. The Buyer supports the use of recycled-content products of all types. Recycled-content products help conserve natural resources, including water and energy, and reduce demands upon landfills.

The Seller shall submit all written documents on paper with a minimum of 30 percent post-consumer recycled content. Existing company/corporate letterhead/stationery that accompanies these documents is exempt from this requirement. Documents of two or more pages in length shall be duplex-copied (double-sided pages). Neon or fluorescent paper shall not be used in any written documents submitted to Buyer.

(b) Non-Discrimination/Equal Employment Practices/Affirmative Action Construction & Non-Construction Agreements. During the performance of this Agreement, Seller shall not discriminate in its employment practices against any employee or applicant for employment because of race, religion, national origin, ancestry, sex, age or physical handicap. All subcontracts awarded under this Agreement shall contain a like nondiscrimination provision. The applicable provisions of Executive Order No. 11246 of September 24, 1965; Part 60-741 of 41 Code of Federal Regulations pertaining to handicapped workers, including 60-741.4 Affirmative Action Clause; and Sections 10.8 to 10.13 of the Los Angeles Administrative Code pertaining to nondiscrimination in employment in the performance of City of Los Angeles contracts are incorporated herein by reference and made a part hereof as if they were fully set forth herein.

Each of the above documents, if approved, shall be effective for twelve (12) months following the date of approval for the Affirmative Action practices.

(c) Supplier Diversity. It is the policy of Buyer to provide Minority Business Enterprises (“MBEs”), Women Business Enterprises (“WBEs”) and all other business enterprises an equal opportunity to participate in the performance of all LADWP agreements/contracts. The Seller shall assist LADWP in implementing this policy and shall use its reasonable efforts to attain MBE and WBE participation of 15 percent and 7 percent, respectively, and to ensure that all available business enterprises, including MBEs and WBEs, have an equal opportunity to compete for and participate in the work of this Agreement.

(1) MBE/WBE Defined. “Minority Business Enterprise” (“MBE”) or “Women’s Business Enterprise” (“WBE”), as used herein means a business enterprise that meets both of the following criteria:

(2) A business that is at least 51 percent owned by one or more minority person(s) or women or, in the case of any business whose stock is publicly held, at least 51 percent of the stock is owned by one or more minority person(s) or women.

(3) A business whose management and daily business operations are controlled by one or more minority person(s) or women.

(d) Taxpayer Identification Number (TIN). Seller declares that its authorized TIN is 20 8740764. No payment will be made under this Agreement without a valid TIN number.

Section 15.23 Service Contract. The Parties intend that this Agreement will qualify as a “service contract” as such term is used in Section 7701(e) of the Code.

Trustor hereby grants to Beneficiary, its agents, attorneys, employees, consultants, contractors, successors and assigns, an irrevocable license and authorization, upon reasonable notice, to enter upon and inspect the Subject Property and facilities thereon, and perform such tests (including without limitation, if a Phase I Environmental Site Assessment, as hereinafter defined, provides evidence of a breach of Trustor’s covenants with respect to Hazardous Materials hereunder, subsurface testing, soils and groundwater testing, and other tests which may physically invade the Subject Property) as Beneficiary, in its reasonable discretion, determines are necessary to protect its interest in the Subject Property or in connection with any foreclosure (or transfer in lieu of foreclosure) with respect to the Subject Property; provided, however, that under no circumstances shall Beneficiary be obligated to perform such inspections or tests, and provided further that Beneficiary indemnifies Trustor for the gross negligence or willful misconduct of Beneficiary with respect to any such tests. In making such inspections, Beneficiary shall be accompanied by a representative of Trustor, if requested by Trustor, and shall comply with Trustor’s safety requirements. Trustor shall make its representative reasonably available to Beneficiary in order to accommodate Beneficiary’s inspections as provided in this paragraph. The term “Phase I Environmental Site Assessment” shall mean an assessment of the environmental condition of the Real Estate conducted in accordance with American Society for Testing Materials (“ASTM”) standards.

l. Indemnity. Trustor agrees to indemnify and hold Beneficiary, its directors, employees, agents, and its successors and assigns, harmless from and against any and all claims, losses, damages, liabilities, fines, penalties, charges, judgments, administrative orders, remedial action requirements, enforcement actions of any kind, and all costs and expenses incurred in connection therewith (including without limitation reasonable attorneys’ fees and expenses) arising directly or indirectly, in whole or in part, out of any failure of Trustor to comply with the environmental representations, warranties, and covenants contained herein. This indemnity shall in no way diminish any additional indemnification obligations of the parties set forth in the Power Purchase Agreement.

m. Continuation of Representations, Warranties, Covenants and Indemnities. Trustor’s representations, warranties, covenants, and indemnities contained herein shall survive the occurrence of any event whatsoever, including, without limitation, the satisfaction of the obligations secured hereby, the reconveyance or foreclosure of this Deed of Trust, the acceptance by Beneficiary of a deed in lieu of foreclosure, or any transfer or abandonment of the Subject Property

n. Beneficiary’s Performance. If Trustor fails to pay or perform any of its obligations herein contained (including payment of expenses of foreclosure and court costs), Beneficiary may (but need not), as agent or attorney-in-fact of Trustor, make any payment or perform (or cause to be performed) any obligation of Trustor hereunder, in any form and manner deemed expedient by Beneficiary, and any amount so paid or expended (plus reasonable compensation to Beneficiary for its out-of-pocket and other expenses for each matter for which it acts under this Deed of Trust), with interest thereon at the rate of one percent (1%) per month, or the maximum rate permitted by law, whichever is less (the “Default Rate”), shall be added to amount hereby secured and shall be repaid to Beneficiary upon demand. By way of illustration and not in limitation of the foregoing, Beneficiary may (but need not) do all or any of the following: make lease payments, payments of principal or interest, or other amounts on the Ground Lease or the BLM Grants and any other lien, encumbrance or charge on any of the Subject Property; complete construction; make payments with respect to maintaining and operating the Subject Property, make repairs; obtain insurance and pay premiums therefor; purchase, discharge, compromise or settle any tax lien or any other lien, encumbrance, suit, proceeding, title or claim thereof; contest any tax or assessment; and redeem from any tax sale or forfeiture affecting the Subject Property. In making any payment or securing any performance relating to any obligation of Trustor hereunder, Beneficiary shall be the sole judge of the legality, validity and amount of any lien or encumbrance and of all other matters necessary to be determined in satisfaction thereof. No such action of Beneficiary shall ever be considered as a waiver of any right accruing to it on account of the occurrence of any matter which constitutes a Default or a breach of Trustor’s obligations under this Deed of Trust.

o. Subrogation. To the extent that Beneficiary, on or after the date hereof, pays any sum under any provision of law or any instrument or document creating any lien or other interest prior or superior to the lien of this Deed of Trust, Beneficiary shall have and be entitled to a lien or other interest on the Subject Property equal in priority to the lien or other interest discharged and Beneficiary shall be subrogated to, and receive and enjoy all rights and liens possessed, held or enjoyed by, the holder of such lien, which shall remain in existence and benefit Beneficiary in securing the obligations secured hereby.

p. Covenants Regarding Ground Leases, BLM Grants, and Appurtenance Instruments.

i. Each of the Ground Leases, BLM Grants and other instruments creating Trustor’s rights in the Appurtenances, including, written easements, licenses, crossing permits or other permits or agreements within the Subject Property (the “Appurtenance Instruments”) is valid and is in full force and effect in accordance with the terms thereof and has not been modified except as herein set forth. All of the rents and other charges due and payable under the Ground Leases, BLM Grants and Appurtenance Instruments prior to the execution

E-7

hereof have been paid, all of the terms, conditions and agreements contained in the Ground Leases, BLM Grants and Appurtenance Instruments have been performed and no default exists under any of the Ground Leases, BLM Grants, or Appurtenance Instruments. This Deed of Trust is lawfully executed and delivered and is, and will be kept, a valid lien on the interests of Trustor therein.

ii. Trustor will promptly pay, or cause to be paid, all rents, charges and other sums or amounts required to be paid by Trustor under the terms of the Ground Leases, BLM Grants, and Appurtenance Instruments and will further timely and fully keep and perform all of the covenants, terms, conditions and provisions of the Ground Leases, BLM Grants, and Appurtenance Instruments required to be performed and complied with by the tenant or grantee thereunder, and will not do or suffer to be done anything the doing of which, or refrain from doing anything the omission of which, will materially impair or have a material adverse effect upon the security of this Deed of Trust. Trustor shall provide evidence of such payments promptly upon the written request of Beneficiary. Until the obligations secured hereby have been indefeasibly paid in full, Trustor shall exercise all options to renew the Ground Leases, BLM Grants, and Appurtenance Instruments to the extent provided for in such agreements. Trustor shall do, or cause to be done, all things necessary to preserve and keep unimpaired the rights of Trustor as lessee or grantee under the Ground Leases, BLM Grants, and Appurtenance Instruments and to prevent any default under such agreements or any termination, surrender, cancellation, forfeiture or impairment thereof, except as permitted under the Power Purchase Agreement.

iii. Except as permitted or required under the Power Purchase Agreement and under Section 3(p)(ii) above, Trustor shall not extend, supplement, cancel or surrender or in any material way modify the terms of any Ground Lease, the BLM Grants, or Appurtenance Agreements without Beneficiary’s prior written consent, which consent shall not be withheld unless such action is likely to adversely affect the security of this Deed of Trust. Trustor expressly releases and surrenders unto Beneficiary all its right, power and authority to cancel, surrender, amend, modify, supplement or alter in any way the terms and provisions of the Ground Leases, BLM Grants, or Appurtenance Agreements, except as specifically provided in the Power Purchase Agreement or except with Beneficiary’s prior written consent, which consent not be withheld unless such action is likely to adversely affect the security of this Deed of Trust. Trustor will use commercially reasonable efforts to enforce the provisions of the Ground Leases, BLM Grants, and Appurtenance Instruments short of termination thereof to the end that Trustor may enjoy all of the rights granted to it as lessee or grantee under the Ground Leases, BLM Grants, or Appurtenance Agreements. Trustor will promptly notify Beneficiary of any material breach by the lessor or grantor under any of the Ground Leases, BLM Grants, or Appurtenance Agreements, and of any inability of such lessor or grantor to perform its obligations under any of the Ground Leases, BLM Grants, or Appurtenance Agreements. Upon a Default, Trustor assigns to Beneficiary the proceeds of any claim Trustor may have against such lessor or grantor for such breach or inability. In the event of a Default or a material breach by Trustor of its obligations under this Deed of Trust, Beneficiary shall have the sole right to choose either (i) to proceed against such lessor or grantor in Trustor’s name or in Beneficiary’s name as agent for Trustor, and Trustor agrees to cooperate with Beneficiary in such action and to execute all documents required by Beneficiary in furtherance of such action, or (ii) to have Trustor proceed on its and Beneficiary’s behalf, in which event Beneficiary may participate in

E-8

such proceedings, and Trustor will deliver to Beneficiary all documents required by Beneficiary for such participation. Trustor shall, at its expense, diligently prosecute such proceedings, shall deliver to Beneficiary copies of all papers served in connection therewith and shall consult and cooperate with Beneficiary and its attorneys and agents, provided that no settlement of such proceedings may be made by Trustor without Beneficiary’s prior written consent.

iv. Trustor shall promptly notify Beneficiary of any material default by Trustor under any Ground Lease, BLM Grant or Appurtenance Instrument, or of the receipt by it of any notice of default from the lessor or grantor thereunder or notice of termination of any Ground Lease, BLM Grant or Appurtenance Instrument pursuant to the provisions thereof and shall furnish to Beneficiary promptly any and all information which Beneficiary may reasonably request concerning the performance by Trustor of the covenants of the Ground Leases, the BLM Grants, the Appurtenance Instruments, or of this Deed of Trust. Trustor shall promptly deposit with Beneficiary a copy of the Ground Leases, BLM Grants, and the Appurtenance Instruments, certified as true, correct and complete by Trustor, and any and all documentary evidence received by it showing compliance by Trustor with the provisions of the Ground Leases, BLM Grants, and Appurtenance Instruments, and will also deliver to Beneficiary a copy of any notice, communication, plan, specification or other instrument or document received or given by it in any way relating to or affecting the Ground Leases, BLM Grants, or Appurtenance Instruments, which may adversely affect the estate of the lessor or the lessee in or under the Ground Leases or in the real estate thereby demised, or the estate of the Trustor under the BLM Grants or Appurtenance Instruments.

q. Covenants Regarding Facility Transmission Line Interests and the Facility Common Facilities’ Interests.

i. Trustor has provided Beneficiary with true and correct copies of all easements, rights of way, common ownership, maintenance and other agreements existing with regard to the Facility Transmission Line Interests and the Facility Common Facilities’ Interests (collectively, and together with any other similar agreement entered into by Trustor after the date hereof, the “Transmission and Common Facility Agreements”). Each of the Transmission and Common Facility Agreements is a valid and existing agreement, is in full force and effect in accordance with the terms thereof and has not been modified, except as set forth herein. All of payments and other charges payable by Trustor under the Transmission and Common Facility Agreements prior to the execution hereof have been paid, all of the terms, conditions and agreements contained in the Transmission and Common Facility Agreements have been performed and no default exists under the Transmission and Common Facility Agreements.

Trustor will promptly pay, or cause to be paid, all rents, charges and other sums or amounts required to be paid by Trustor under the terms of the Transmission and Common Facility Agreements, will further timely and fully keep and perform all of the covenants, terms, conditions and provisions of the Transmission and Common Facility Agreements required to be performed and complied with by Trustor thereunder, and will not do or suffer to be done anything the doing of which, or refrain from doing anything the omission of which, will impair the security of this Deed of Trust. Trustor shall provide evidence of such payments promptly upon the request of Beneficiary. Until the obligations secured hereby have

E-9

been indefeasibly paid in full, Trustor shall keep the Transmission and Common Facility Agreements in full force and effect. Trustor shall do, or cause to be done, all things necessary to preserve and keep unimpaired the rights of Trustor under the Transmission and Common Facility Agreements and to prevent any default that will impair or have an adverse effect upon the security of this Deed of Trust under the Transmission and Common Facility Agreements, or any termination, surrender, cancellation, forfeiture or impairment thereof.

iii. Trustor covenants that it will not modify, extend, supplement or cancel any of the Transmission and Common Facility Agreements as to which Beneficiary has rights of review and approval under Sections 2.7 or 2.8 of the Power Purchase Agreement, or waive or release the other parties thereto of or from any obligations, conditions or agreements by said parties, and shall not have the power to do so, without Beneficiary’s prior written consent, which consent shall be granted upon confirmation by Beneficiary that such action is not likely to have a material adverse effect on, or materially increase the risk of Beneficiary with regard to, the security provided to Beneficiary under this Deed of Trust. Trustor agrees to promptly notify Beneficiary of any breach by any party to the Transmission and Common Facility Agreements and to enforce the obligations of the other parties to the Transmission and Common Facility Agreements, to the end that Trustor may enjoy all of its rights under the Transmission and Common Facility Agreements. In the event of a Default or a material breach by Trustor of its obligations under this Deed of Trust, Beneficiary shall have the sole right to choose either (i) to proceed against such other parties in Trustor’s name or in Beneficiary’s name as agent for Trustor, and Trustor agrees to cooperate with Beneficiary in such action and to execute all documents required by Beneficiary in furtherance of such action, or (ii) to have Trustor proceed on its and Beneficiary’s behalf, in which event Beneficiary may participate in such proceedings, and Trustor will deliver to Beneficiary all documents required by Beneficiary for such participation. Trustor shall, at its expense, diligently prosecute such proceedings, shall deliver to Beneficiary copies of all papers served in connection therewith and shall consult and cooperate with Beneficiary and its attorneys and agents, provided that no settlement of such proceedings may be made by Trustor without Beneficiary’s prior written consent.

iv. Trustor shall promptly give Beneficiary notice of any material default by Trustor under the Transmission and Common Facility Agreements or of the receipt by it of any notice of default from any party thereunder or notice of termination of any of the Transmission and Common Facility Agreements pursuant to the provisions thereof and shall furnish to Beneficiary promptly any and all information which Beneficiary may reasonably request concerning the performance by Trustor of the covenants of the Transmission and Common Facility Agreements. Upon the request of Beneficiary, Trustor shall promptly deposit with Beneficiary a copy of the Transmission and Common Facility Agreements, certified as true, correct and complete by Trustor, and any and all documentary evidence received by it showing compliance by Trustor with the provisions of the Transmission and Common Facility Agreements.

r. Bankruptcy Rights and Remedies. The lien of this Deed of Trust attaches to all of Trustor’s rights and remedies at any time arising under or pursuant to Section 365 of the Bankruptcy Code (the “Bankruptcy Code”), including, without limitation, all of Trustor’s rights to remain in possession of the Subject Property. Trustor shall not commence any action, suit, proceeding or case, or file any application or make any motion, in respect of the Ground Leases,

E-10

BLM Grants, or Appurtenance Instruments in any such case under the Bankruptcy Code without the prior written consent of Beneficiary. Trustor shall promptly, after obtaining knowledge thereof, notify Beneficiary orally of any filing by or against the lessor or Trustor of a petition under the Bankruptcy Code. Trustor shall thereafter forthwith give written notice of such filing to Beneficiary, setting forth any information available to Trustor as to the date of such filing, the court in which such petition was filed and the relief sought therein. Trustor shall promptly deliver to Beneficiary, following receipt, any and all notices, summons, pleadings, applications and other documents received by Trustor in connection with any such petition and any proceedings relating thereto.

s. Beneficiary’s Lease. Notwithstanding the provisions of the foregoing paragraphs regarding termination of the Ground Leases, BLM Grants, or Appurtenance Instruments, upon a termination or rejection of one or more of the Ground Leases, BLM Grants, or Appurtenance Instruments by or for Trustor as a debtor under the Bankruptcy Code, Trustor acknowledges that Beneficiary may enter into (1) an instrument recognizing, confirming and giving legal effect to the continued existence of such Ground Lease, BLM Grant, or Appurtenance Instrument in favor of Beneficiary or its designee, or (2) a new lease or right-of-way grant in favor of Beneficiary or its designee (in either event the “Beneficiary’s Lease”) for the Subject Property pursuant to the terms of such Ground Lease, BLM Grant, or Appurtenance Instrument, or the provisions of a separate agreement between Beneficiary and the lessor, in such event, Beneficiary’s execution of the Beneficiary’s Lease shall not be deemed to be in satisfaction in whole or in part of the obligations secured hereby and all of the other terms, covenants and conditions contained in this Deed of Trust shall remain as a lien on the Subject Property. Trustor hereby releases, remises, and quitclaims to Beneficiary any interest Trustor may have in the Beneficiary’s Lease and further agrees and acknowledges that Beneficiary may assign the Beneficiary’s Lease without notice, consent or joinder of Trustor. Trustor further waives any right Trustor may have to challenge the adequacy of any consideration received therefore.

4. Default and Remedies. Should (i) a Default occur under the Power Purchase Agreement, as provided and defined therein; (ii) Trustor fail to pay any amount when due under this Deed of Trust or other amounts due under any Ground Lease, BLM Grant, Appurtenance Instrument, any of the Transmission and Common Facility Agreements, or other Intangible Rights and Interests, which is not cured within thirty (30) days after receiving written notice thereof from Beneficiary or such shorter cure period that may be provided under any such Ground Lease, BLM Grant, Appurtenance Instrument, or any of the Transmission and Common Facility Agreements; or (iii) Trustor fail to perform any of its other material duties or obligations under this Deed of Trust, which failure is not cured within sixty (60) days after receipt of written of such failure from Beneficiary (provided that if (A) such breach cannot be cured within such period, (B) such breach is susceptible of cure within an additional thirty (30) days, (C) Trustor is proceeding with diligence and in good faith to cure such breach, and (D) the existence of such breach has not resulted in, and would not after considering the nature of the cure be reasonably expected to give rise to, a termination by the counterparty to any Ground Lease, BLM Grant, Appurtenance Instrument, or Transmission and Common Facility Agreement, or other Intangible Rights and Interests which is subject to breach, or to otherwise have a material adverse effect on the Subject Property or the validity or priority of Beneficiary’s security interests and lien on the Subject Property, then such cure period shall be extended an additional thirty (30) days), then

E-11

Beneficiary shall have the right to foreclose the lien of this Deed of Trust. In addition, Beneficiary may exercise any remedy available at law or in equity or under the Power Purchase Agreement to Beneficiary, including but not limited to those listed below, in such sequence or combination as Beneficiary may determine in Beneficiary’s sole discretion:

a. Performance of Defaulted Obligations. Beneficiary may make any payment or perform any other obligation under this Deed of Trust which Trustor has failed to make or perform as provided for herein. All payments made and expenses (including reasonable attorney’s fees) incurred by Beneficiary in this connection, together with interest thereon at the Default Rate from the date paid or incurred until repaid, will be part of the obligations secured by this Deed of Trust and will be immediately due and payable by Trustor to Beneficiary. In lieu of advancing Beneficiary’s own funds for such purposes, Beneficiary may use any funds of Trustor which may be in Beneficiary’s possession, including but not limited to insurance or condemnation proceeds and amounts deposited for taxes, insurance premiums, or other purposes.

b. Specific Performance and Injunctive Relief. Notwithstanding the availability of legal remedies, Beneficiary will be entitled to obtain specific performance, mandatory or prohibitory injunctive relief, or other equitable relief requiring Trustor to cure or refrain from repeating any default.

c. Possession of Subject Property. Beneficiary may enter and take possession of the Subject Property without seeking or obtaining the appointment of a receiver, may employ a managing agent for the Subject Property, and may lease or rent all or any part of the Subject Property, either in Beneficiary’s name or in the name of Trustor, and may collect the rents, issues, and profits of the Subject Property. Any revenues collected by Beneficiary under this section will be applied first toward payment of all expenses (including reasonable attorney’s fees) incurred by Beneficiary, together with interest thereon at the Default Rate from the date incurred until repaid, and the balance, if any, will be applied against the obligations secured hereby.

d. Other Remedies. Beneficiary may exercise all rights and remedies set forth in the Power Purchase Agreement or in this Deed of Trust, including all rights of a secured party under the UCC, as defined in Article 5 hereof.

e. Foreclosure.

i. Trustee’s Sale. Beneficiary may foreclose this Deed of Trust by way of a trustee’s sale pursuant to the provisions of Title 57, Chapter 1, Utah Code Annotated, as currently in effect, as amended, or in any other manner then permitted by law (“Trustee’s Sale”). After the lapse of such time as may then be required by law following the recordation of said notice of default, and notice of default and notice of sale having been given as then required by law, Trustee, without demand on Trustor, shall sell the Subject Property on the date and at the time and place designated in said notice of sale, either as a whole or in separate parts or parcels, and in the absence of direction by Trustor, in such order as it may determine, at public auction to the highest bidder, the purchase price payable in lawful money of the United States at the time of the sale. To the extent allowed by law, the person conducting the sale may, for any cause he or she deems expedient, postpone the sale from time to time until it shall be completed and, in

E-12

every such case, postponement shall be given by public declaration thereof at the time and place last appointed for sale. Trustee shall execute and deliver to the purchaser its trustee’s deed conveying said property so sold, but without any covenant or warranty, express or implied. The recitals in the trustee’s deed of any matters or facts shall be conclusive proof as to bona fide third parties of the truthfulness thereof. Any person, including Beneficiary, may bid at the sale. Trustee shall apply the proceeds of the sale to payment of (1) the costs and expenses of exercising the power of sale and of the sale, including the payment of Trustee’s and reasonable attorney’s fees; (2) the obligations secured hereby; and (3) the remainder, if any, to the person or persons entitled thereto.

ii. Judicial Foreclosure. Beneficiary shall also have the right to foreclose this Deed of Trust as a mortgage by appropriate proceedings in any court of competent jurisdiction (“Judicial Foreclosure”).

iii. Expenses of Trustee’s Sale or Foreclosure. All reasonable fees, costs and expenses of any kind incurred by Beneficiary in connection with foreclosure of this Deed of Trust, including, without limitation, the reasonable costs of any appraisals of the Subject Property obtained by Beneficiary, all reasonable costs of any receivership for the Subject Property advanced by Beneficiary, and all reasonable attorneys’ and consultants’ fees incurred by Beneficiary, appraisers’ fees, outlays for documentary and expert evidence, stenographers’ charges, publication costs and costs (which may be estimates as to items to be expended after entry of the decree) of procuring all such abstracts of title, title searches and examination and similar data and assurances with respect to title, as Trustee or Beneficiary may deem necessary either to prosecute such suit or to evidence to bidders at the sales that may be had pursuant to such proceedings the true conditions of the title to or the value of the Subject Property, together with and including a reasonable compensation to Trustee, shall constitute a part of the obligations secured hereby and may be included as part of the amount owing from Trustor to Beneficiary at any foreclosure sale.

iv. Proceeds of Trustee’s or Foreclosure Sale. The proceeds of foreclosure sale of the Subject Property shall be distributed and applied in the following order of priority: first, on account of all costs and expenses incident to the foreclosure proceedings, second, to the obligations secured hereby, and lastly, to Trustor, or, if applicable to such person or persons legally entitled thereto.

v. Insurance Upon Foreclosure. In case of an insured loss after Judicial Foreclosure or Trustee’s Sale proceedings have been instituted, the proceeds of any insurance policy or policies, if not applied to rebuilding or restoring the buildings or improvements, shall be used to pay the amount due under the obligations secured hereby. In the event of Judicial Foreclosure or Trustee’s Sale, Beneficiary or Trustee is hereby authorized, without the consent of Trustor, to assign any and all insurance policies to the purchaser at the sale, or to take such other steps as Beneficiary or Trustee may deem advisable to cause the interest of such purchaser to be protected by any of the said insurance policies.

f. Appointment of Receiver. Beneficiary shall be entitled to the appointment of a receiver. Such receiver and his agents shall be empowered (a) to take possession of the Subject Property and any businesses conducted by Trustor or any other person (other than the

E-13

lessor or other persons authorized by the lessor with respect to any rights to use portions of the Subject Property retained by the lessor as provided in the Ground Leases or by the BLM under the BLM Grants) thereon and any business assets used in connection therewith and, if the receiver deems it appropriate, to operate the same, (b) to exclude Trustor and Trustor’s agents and employees from the Subject Property, (c) to collect the rents, issues, profits, and income therefrom, (d) to complete any construction which may be in progress, (e) to do such maintenance and make such repairs and alterations as the receiver deems necessary, (f) to pay all taxes and assessments against the Subject Property and all premiums for insurance thereon, (g) to pay all utility and other operating expenses, and all sums due under any prior or subsequent encumbrance, and (h) generally to do anything which Trustor could legally do if Trustor were in possession of the Subject Property. All reasonable expenses incurred by the receiver or his agents shall constitute a part of the obligations secured hereby. Any revenues collected by the receiver shall be applied first to the expenses of the receivership, including reasonable attorneys’ fees incurred by the receiver and by Beneficiary, together with interest thereon at the Default Rate from the date incurred until repaid, and the balance shall be applied toward the obligations secured hereby and then to Trustor or in such other manner as the court may direct. Unless sooner terminated with the express consent of Beneficiary, any such receivership will continue until the obligations secured hereby have been discharged in full, or until title to the Subject Property has passed after foreclosure sale and all applicable periods of redemption have expired.

g. Right to Make Repairs, Improvements. Should any part of the Subject Property come into the possession of Beneficiary after a Default under the Power Purchase Agreement, as provided and defined therein, or after a default under this Deed of Trust, Beneficiary may use, operate, and/or make repairs, alterations, additions and improvements to the Subject Property for the purpose of preserving it or its value. Trustor covenants to promptly reimburse and pay to Beneficiary, at the address set forth in the first paragraph of this Deed of Trust, or at such other place as may be designated by Beneficiary in writing, the amount of all reasonable expenses (including the cost of any insurance, taxes, or other charges) incurred by Beneficiary in connection with its custody, preservation, use or operation of the Subject Property, together with interest thereon from the date incurred by Beneficiary at the Default Rate, and all such expenses, costs, taxes, interest, and other charges shall be a part of the obligations secured hereby. It is agreed, however, that the risk of accidental loss or damage to the Subject Property is undertaken by Trustor and, except for Beneficiary’s willful misconduct or gross negligence, Beneficiary shall have no liability whatsoever for decline in value of the Subject Property, for failure to obtain or maintain insurance, or for failure to determine whether any insurance ever in force is adequate as to amount or as to the risks insured.

h. Waivers. To the full extent that the covenants and waivers contained in this paragraph are permitted by law, but not otherwise, Trustor hereby waives any and all rights under, and covenants and agrees that it will not at any time insist upon or plead or in any manner whatsoever claim or take advantage of, any stay, exemption, moratorium or extension law now or hereafter in effect or any law now or hereafter in effect providing for the valuation or appraisement of the Subject Property or any part thereof prior to any sale or sales thereof and Trustor will not invoke or utilize any such law or laws or otherwise hinder, delay or impede the execution of any right, power or remedy herein or otherwise granted or delegated to Trustee or Beneficiary, but will suffer and permit the execution of every such right, power and remedy as though no such law or laws have been made or enacted.

E-14

5. Uniform Commercial Code. This Deed of Trust, to the extent that it conveys or otherwise deals with (i) personal property, or (ii) items of personal property which are or may become fixtures, shall also be construed as a security agreement under the Uniform Commercial Code as in effect in the state of Utah (“UCC”), and this Deed of Trust constitutes a financing statement filed as a fixture filing in the Official Records of the county recorder of the county or counties in which the Subject Property, or any portion thereof is located with respect to any and all fixtures included within the term “Subject Property” as used herein and with respect to any personal property that may now be or hereafter become such fixtures. For purposes of the foregoing, Trustor is the debtor and owner of the Subject Property (with its address as set forth above), Beneficiary is the secured party (with its address as set forth below). Trustor grants to Beneficiary a valid and effective first priority security interest in all of Trustor’s right, title and interest in and to all portions of the Subject Property which constitute personal property, together with all replacements, additions, and proceeds. Except for Permitted Encumbrances, Trustor agrees that, without the written consent of Beneficiary and except as otherwise permitted under the Power Purchase Agreement, no other security interest will be created under the provisions of the UCC and no lease having a market value of over $500,000 will be entered into with respect to any goods, fixtures, equipment, appliances, or articles of personal property now attached to or used or to be attached to or used in connection with the Subject Property; provided that any lease entered into by Trustor having a market value of over $50,000 shall constitute Subject Property subject to the security interest under this Deed of Trust. Subject to the cure provisions of Article 4 herein, upon Trustor’s failure to perform any of its material obligations under this Deed of Trust or upon the occurrence of a Default under the Power Purchase Agreement, as provided and defined therein, Beneficiary shall have the remedies of a secured party under the UCC and, at Beneficiary’s option, may also invoke the power of sale and all other remedies provided in this Deed of Trust as to the personal property and any other items of the Subject Property subject to this security interest. In exercising any remedies, Beneficiary may proceed against the items of Real Estate and any other items of personal property specified in Article 1 as part of the Subject Property separately or together and in any order whatsoever, without in any way affecting the availability of Beneficiary’s remedies under the UCC or of the remedies provided in this Deed of Trust.

6. Beneficiary’s Actions. Without affecting the lien of this instrument, Beneficiary may, from time to time, release any obligation, extend, alter or renew the terms of payment or performance, substitute security, and/or release any portion of the Subject Property.

7. Reconveyance by Trustee. Trustee may from time to time and only upon the written request of Beneficiary, reconvey, without warranty, any part of said property and/or join in any agreement subordinating the lien or charge hereof.

8. Partial Payment. The acceptance by Beneficiary of any sum in payment, or part payment, of any obligation secured hereby, after the same is due or after the recording of a notice of default, shall not be considered a waiver of the right to require prompt payment when due, of other sums, nor shall such acceptance cure or waive any remaining default or invalidate any sale held pursuant to Notice for any remaining default.

9. Severability. The invalidity of any one or more covenants, phrases, clauses, sentences or paragraphs of this Deed of Trust shall not affect the remaining portions of this Deed

E-15

of Trust or any part thereof, and this Deed of Trust shall be construed as if such invalid covenants, phrases, clauses, sentences or paragraphs, if any, had not been inserted herein.

The designated address of a party shall be the address of that party shown at the beginning of this Deed of Trust or such other address as that party, from time to time, may specify by notice to the other parties.

12. Termination of Deed of Trust.

I. GENERAL REQUIREMENTS

Prior to the start of work, but not later than thirty (30) days after the date of award of contract, Seller shall furnish Buyer evidence of coverage from insurers acceptable to Buyer and in a form acceptable to Buyer’s Risk Manager. Such insurance shall be maintained by Seller at Seller’s sole cost and expense.

Such insurance shall not limit or qualify the liabilities and obligations of Seller assumed under this Agreement. Buyer shall not by reason of its inclusion under these policies incur liability to the insurance carrier for payment of premium for these policies.

Any insurance carried by Buyer which may be applicable shall be deemed to be excess insurance and Seller’s insurance is primary for all purposes despite any conflicting provision in Seller’s policies to the contrary.

Said evidence of insurance shall contain a provision that the policy cannot be canceled or reduced in coverage or amount without first giving thirty (30) calendar days prior notice thereof (ten (10) days for non-payment of premium) to Southern California Public Power Authority, 225 S. Lake Avenue, Suite 1250, Pasadena, California 91101.

Should any portion of the required insurance be on a “Claims Made” policy, Seller shall, at the policy expiration date following completion of work, provide evidence that the “Claims Made” policy has been renewed or replaced with the same limits, terms and conditions of the expiring policy, or that an extended discovery period has been purchased on the expiring policy at least for the contract under which the work was performed.

Failure to maintain and provide acceptable evidence of the required insurance for the required period of coverage shall constitute a breach of contract, upon which Buyer may immediately terminate or suspend the Agreement.

Seller shall be responsible for all subcontractors’ compliance with the insurance requirements. All contractors and subcontractors shall maintain the same types of insurance with limits and terms that are normal and customary for the industry and types of services being provided.

Without limiting the generality of the foregoing, Lessee shall have, subject to the limitations contained in this Lease, the following rights and privileges under this Lease:

3.1 The right to develop, erect, construct, install, replace, repair, relocate, remove, maintain, operate, and use, from time to time, WTGs, underground and above-ground electrical transmission and communications lines related to the operation of WTGs, electric transformers and substations, energy storage facilities, telecommunications equipment, roads, meteorological towers and wind measurement equipment, control buildings, maintenance yards, and related facilities and equipment on the Leased Property, which WTGs may be integrated with each other and with WTGs located on other properties;

3.2 The right to capture and to convert any or all of the wind resources of premises.

3.3 The right to investigate the potential of wind energy conversion but not limited to, conducting environmental and paleontological studies, soil tests, and studies of wind speed, wind direction and other meteorological data and geological studies, and other studies as may be required in connection with permitting the WTGs;

3.4 The right to develop, erect, construct, install, replace, repair, relocate, remove, maintain, operate, and use the following from time to time in connection with the WTGs (i) a line or lines of poles or towers, together with such wires and cables as from time to time are suspended there from, and/or underground wires and cables, for the transmission of electrical energy and/or for communication purposes, and all necessary and proper anchors, support structures, foundations, footings, crossarms and other appliances and fixtures for use in connection with said towers, wires and cables; (ii) one or more substations or interconnection or switching facilities from which the WTGs may interconnect to a utility transmission system or the transmission system of another purchaser of electrical energy; and (iii) roads associated with

H-3

the foregoing (such towers, wires, cables, substations, facilities and other enumerated items in clauses (i), (ii) and (iii) are herein collectively called the “Transmission Facilities”);

3.5 The right of pedestrian and vehicular ingress, egress, and access over and across the Leased Property by means of roads and lanes thereon if existing, or otherwise by such roads, structure, route or routes as Lessee may construct or improve from time to time (“Transportation Facilities”);

3.6 The right of subjacent and lateral support to whatever is necessary for the operation and maintenance of improvements on the Leased Property and other property used in connection with Wind Energy Improvements, including, without limitation, guy wires and supports;

3.7 The right to permit the rotors of WTGs located on adjacent properties to overhang the Leased Property and the right to permit the rotors of WTGs on the Leased Property to overhang any adjacent property owned by Lessor;

3.8 The right to grade, level, fill, clear and replant ground; and to excavate and use sand, gravel, caliche or other materials suitable for road cover solely to construct the Transportation Facilities on the Leased Property, all to the extent permitted by law and only at locations and in amounts approved by Lessor in its reasonable discretion;

3.9 The right to enter upon the Premises and to conduct Phase I and other environmental studies or audits of the Premises, including the air, soil, and water in and about the Premises, at any time; and

3.10 The right to undertake any other activities, whether accomplished by Lessee or a third party authorized by Lessee, that are reasonably necessary, useful or appropriate to accomplish any of the purposes or uses of the Lease set forth above.

4. USES RESERVED BY LESSOR

4.1 Subject to Subsections 4.2 (including Sub-subsection 4.2.6) and 13.3 below, Lessor expressly reserves all rights to use the Leased Property (excluding any Wind Rights) for purposes not granted to Lessee, including the installation and operation of animal husbandry facilities, to the extent that the lawful exercise of such reserved rights does not materially interfere with the construction, operation, or maintenance of the Improvements. Lessor will give sixty (60) days’ prior written notice to Lessee of any intended and new material use or development of the Premises or Other Appurtenances. If Lessee believes that interference with Lessee’s use of such Premises and Other Appurtenances will result from the proposed use of the Premises and Other Appurtenances by Lessor or its designees, Lessor will take all steps reasonably necessary to ensure the compatibility of Lessor’s intended use with Lessee’s use of such property. Lessee shall have no liability for costs associated with any use of the Premises or Other Appurtenances by Lessor pursuant to the rights reserved or not granted herein.

4.2 In furtherance of Subsection 4.1, and subject to Sub-subsection 4.2.6 below, in consideration of Lessee’s investment in the Improvements and the other covenants contained in this Lease, Lessor shall limit its future activities on the Premises, and any grant of

H-4

rights Lessor makes to any third party, whether the right of use is located on the Premises or elsewhere, as follows:

4.2.1 Except to the extent specifically provided in this Lease, Lessor shall not, and shall not authorize other persons or entities to, install structures or undertake other activities on the Premises that materially interfere with the wind speed or wind direction over the Premises or materially decrease efficiency of any WTG, including any WTGs located on lands adjoining the Premises, or the installation or operation of the Improvements.

4.2.2 Lessor will not grant or authorize any mineral extraction rights or mineral estates, geothermal rights, hunting rights, or similar types of usage rights on the Premises in a form that materially interferes with the construction or operation of the Improvements or other allowed uses of the Leased Property; provided that Lessor shall have no liability to Lessee for any damages incurred by Lessee and caused by unauthorized uses, or caused by trespasses by unrelated third parties. Lessor shall not interfere with Lessee’s efforts reasonably necessary to mitigate unauthorized uses or trespasses.

4.2.3 Lessor will not, and will not authorize any third party, to construct or install any structure or other improvement that is within the Minimum Distance of any WTG. The Minimum Distance for any such structure is as follows:

MD = 100 tf. + (H*20)

Where: MD = the Minimum Distance

H = maximum height above ground (in ft.) of any structure in excess of 15 tf.

Thus, for example, the Minimum Distance for a building with a maximum height above ground of 20tf. would be calculated as (20f1 -15ft = 5ft=f1; 5ft*20 = 100tf; 100tf + 100tf = 200tf = MD).

4.2.4 Lessor will consult with and obtain Lessee’s prior written approval as to all animal husbandry facilities and other structures constructed under 4.1 to be located by or under the direction of Lessor or its permittees within the Minimum Distance, whether located on or off the Premises. Lessee shall cooperate with Lessor in any such review, and Lessee shall consent to any such structures so long as, based upon appropriate professional engineering and meteorological opinions, the proposed structures at the proposed location are not likely to materially interfere with wind speed or wind direction over any portion of the Premises, cause a material decrease in the output or efficiency of any WTG, or otherwise materially interfere with Lessee’s operations on the Leased Property.

4.2.5 Each of Lessor and Lessee will use good faith, commercially reasonable efforts to avoid or minimize material interference with each Party’s respective operations on the Leased Property.

4.2.6 Notwithstanding the balance of this Subsection 4.2, if Lessee has not commenced commercial electrical power production on the Premises by April 15, 2013, then unless and until such construction commences, Lessor shall have the right to proceed with any use of the Premises reserved by Lessor in Subsection 4.1, but shall not be subject to the

H-5

limitations of Subsubsections 4.2.1 — 4.2.4 above. Thereafter if Lessee elects to commence installation of WTGs and/or Wind Energy Improvements on the Premises, Lessee shall give written notice of its election and the Parties will remain subject to Subsection 4.2.5 above with respect to the design, installation and operation of their respective facilities on the Premises, provided that Lessor shall not be obligated to remove or relocate any facilities or uses previously installed or allowed by it on the Premises. Any such notice from Lessee electing to commence installation of WTGs and/or Wind Energy Improvements on the Premises shall lapse without opportunity for extension or renewal if commercial electrical power production does not commence within two years from the date of the notice.

5. EXCLUSIVENESS OF LEASE. Lessee’s granted rights hereunder to the Wind Rights and rights to erect and maintain WTGs and Wind Energy Improvements on the Premises set forth in Section 3.1-3.4 and 3.6-3.7 are exclusive of all other persons, including Lessor. Without limiting the generality of the foregoing, Lessor covenants not to convey or authorize the exploitation of Wind Rights or otherwise to grant or suffer any conflicting rights with respect to the Leased Property.

6. OWNERSHIP OF WIND ENERGY IMPROVEMENTS. Lessor shall have no ownership or other interest in any Improvements (as defined below). Lessee shall have title to all Improvements at all times, whether or not the same shall be affixed to the Premises, and Lessee may remove any or all such Improvements at any time. As used in this Lease, the term “Improvements” means all facilities or equipment installed on the Leased Property for the purpose of producing electricity by wind power, including but not limited to WTGs, Transmission Facilities, structures, equipment, machinery, wire, conduit, fiber, cable, poles, materials and property of every kind and character constructed, installed and/or placed on, above or below the Leased Property by or on behalf of Lessee. This Lease contemplates that Improvements may be installed at separate times, in multiple stages to create one or more sets of integrated Improvements under separate capital structures and power sales arrangements, each defined as a “Wind Energy Improvement.” The Wind Energy Improvements may share some common facilities such as substations, transmission lines, and roads.

7. TRANSMISSION FACILITIES EASEMENT. Lessee shall have the right to sublease to any utility, power provider, or other party (collectively, “Transmission Facility Assignees”) any of its rights granted hereunder to (a) construct, operate, and maintain the Transmission Facilities on the Leased Property, and (b) access such Transmission Facilities, including the right of ingress and egress into and across portions of the Leased Property and other adjacent property of Lessor, if any. All such sublease rights shall remain subject to the terms and conditions hereof If requested by a Transmission Facility Assignee and Lessee, Lessor will provide written affirmation to such Transmission Facility Assignee of such easements and access rights as granted to Lessee herein (each a “Transmission Facility Easement”).

8. SURVEY AND SITE PLAN. Lessee may survey the Premises and all elements of any Wind Energy Improvements at its own expense. Any site and/or construction plan(s) intended to be used by Lessee with respect to the Improvements, Transportation Facilities, or Transmission Facilities, including any plans required to be filed from time to time in connection with permitting each Wind Energy Improvement, shall be subject to the review and consent of Lessor; provided that such review shall be as timely as practical so as to avoid permitting or

H-6

construction delays, and such consent will be provided so long as such plans maintain a distance between lines of WTGs, such that Lessor may install buildings up to 30 tf. in height above ground between such lines or arrays while conforming to the Minimum Distance. Once accepted by Lessor, Lessee may make immaterial alterations to such plans without prior Lessor consent and shall locate, construct, operate, and replace all Improvements in accordance with such plans. While the wind resource will dictate the location of the WTGs, Lessee shall use commercially reasonable efforts to accommodate requests of Lessor regarding the location of Transportation Facilities, Transmission facilities, and substations. To the best of Lessor’s knowledge and only insofar as such plans have been provided to Lessor by Lessee prior to the execution of this Lease, Lessor has reviewed and approved the site and construction plans intended to be used by Lessee with respect to the Improvements, Transportation Facilities, or Transmission Facilities, including any plans required to be filed from time to time in connection with permitting the Wind Energy Improvement related to the Premises. No review and consent by Lessor shall constitute any warranty of Lessor or create any liability of Lessor. Lessee shall be solely responsible for designing, permitting, financing, constructing, operating, repairing, replacing, and maintaining each Wind Energy Improvement. Lessor is solely responsible for the placement and operation of its facilities on the Premises.

9. TERM

9.1 This Lease shall be effective as of the Effective Date. The initial term of this Lease shall be until the last day in the December following the fortieth (40th) anniversary of the Commencement Date (“Initial Term”). The Lessee shall have the option to renew this Lease for up to two additional ten (10) year terms. If the Lessee is then in possession of the Premises and if there is not a notice of default from Lessor pending at the time the lease term ends (whether at the end of the Initial Term or the first extension), Lessee will be deemed to have exercised its option to extend the term hereof absent Lessee providing a written notice to Lessor to the effect that the extension will not be undertaken. If a notice of default is pending, the lease term may be extended only upon written consent from Lessor. Any such Lessee notice that it will not extend the lease shall be in writing by certified or registered mail, and made on or before sixty (60) days prior to the end of the Initial Term or any extension of the Initial Term. For the purposes of this Section 9, a notice of default shall be deemed to be pending if notice of default has been given by Lessor as provided in Section 18 and the default specified in the notice has not been corrected.

9.2 If the Beaver County Lease terminates pursuant to Section 9.2 of the Beaver County Lease, this Lease shall automatically terminate as of the termination of the Beaver County Lease. If Lessor’s right to terminate the Beaver County Lease pursuant to Section 9.2 thereof is extinguished, this Section 9.2 shall have no further effect. At Lessee’s request and expense, Lessor will provide written acknowledgement in recordable form of the occurrence of Commencement Date.

9.3 When the Lease terminates for any reason, Lessor shall be entitled to file a notice thereof in the office of the recorder of each county in which a portion of the Premises is located.

9.4 Notwithstanding the foregoing, Lessee shall not be entitled to erect WTGs on the Premises until such time as Lessee has demonstrated to Lessor’s reasonable satisfaction that Lessee is financially capable of performing its obligations under Section 21. Within 15 business days of Lessee’s delivery of evidence of Lessee’s financial capability to perform under Section 21, Lessor shall either deliver written notice to Lessee of its acceptance of such evidence or provide a detailed written explanation of its basis for not accepting such evidence. If Lessor fails to respond in writing with such 15-day period, such failure shall be deemed to waive objection to Lessee’s ability to perform its obligations under Section 21 and Lessee shall be entitled to erect WTGs on the Premises.

9.4.1 The evidence of Lessee’s financial capability to be provided under this Subsection 9.4 shall include information represented and warranted by Lessee as providing an accurate and complete statement of Lessee’s financial capability as of the date furnished, together with any other additional assurances reasonably necessary to demonstrate Lessee’s capability under Section 21.

Subject to the specific written consent of Lessor, Lessee may construct, install, maintain and use one or more water wells upon the Leased Property for potable water uses; in such event, Lessor shall retain ownership of all water available from such well(s), but Lessor will allow Lessee to use water from such wells at no cost to Lessee for the limited use of potable water reasonably necessary for Lessee’s personnel and minor cleaning and maintenance. The water rights to be furnished at no cost by Lessor to Lessee shall not exceed 1.0 acre feet per year for all uses under this Lease, except upon the prior written consent of Lessor.

11. USE: GOVERNMENTAL APPROVALS. Lessee’s uses of the Leased Property are subject to receipt of all of the certificates, permits, zoning changes or variances, easements, rights of way, and other federal, state or local authorizations and/or approvals (collectively, the “Governmental Approvals”) that may be required by any federal, state or local government, agency or other authority (“Governmental Authorities”) under any applicable federal, state, or local law, rule, regulation, ordinance, statute, order or decree (“Legal Requirements”) as well as satisfactory soil boring tests which will permit the Lessee use of the Leased Property as set forth above. Lessee shall have the right in its sole discretion, to contest by appropriate legal proceedings, brought in the name of Lessee or in the names of both Lessee and Lessor where appropriate or required, the validity or applicability to the Leased Property, Transmission Facilities, Improvements, or Wind Energy Improvements of any Legal Requirement, Taxes or the like, now or hereafter made or issued by any Governmental Authority. Lessor shall cooperate in every reasonable way in such contest, at no material out-of-pocket expense to Lessor. If any of such Governmental Approvals should be finally rejected or denied or any Governmental Approval issued to the Lessee is canceled, expires, lapses or is otherwise withdrawn or terminated, or soil boring tests are found to be unsatisfactory so that the Lessee in its sole discretion will be unable to use the Leased Property for its intended purposes or the Lessee

H-9

determines that the Leased Property is no longer technically compatible for its intended use, the Lessee shall have the right to terminate this Lease. Notice of the Lessee’s exercise of its right to terminate shall be given to the Lessor in writing by certified mail, return receipt requested, and shall be effective upon the mailing of such notice by the Lessee. Except with respect to any surviving provisions hereof, including provisions with respect to indemnity, taxes, removal of Improvements and any outstanding rent due, this Lease shall become null and void and the Parties shall have no further obligations.

Lessor will consider in good faith, and will not unreasonably withhold its consent to, any request

H-14

by Lessee to self-insure any of the required coverages upon a showing by Lessee of the legality of self-insurance and sufficient financial resources to support a self-insurance program.

14.6 Failure to Obtain Required Insurance. Failure to obtain satisfactory insurance and proof of insurance, or to provide self-insurance and evidence thereof, shall constitute a default under this Lease. If Lessee fails to obtain any types or amounts of insurance required under this Lease, Lessor shall have the right, but shall not be obligated, to immediately obtain such insurance and keep the same in effect. In such an event, Lessee shall pay Lessor the premium costs of such insurance and any other actual costs incurred by Lessor in obtaining such insurance within ten (10) days after demand.

14.7 Increase in Insurance Limits. Lessor may require by written notice an increase in the insurance limits specified in this Section 14 based on inflation or commercial adequacy. The inflation adjustment shall be made by one of the following methods:

14.7.1 The coverage limits for each policy of insurance required shall be increased on each five-year anniversary of the Effective Date using the Inflation Index, with 2007 as the base year, or another index approved in writing by Lessor, for each year that the Inflation Index is greater than the base year. The limits required by this paragraph shall not exceed commercially reasonable limits.

14.7.2 Notwithstanding the provision for inflation adjustment, if the policy limits established by such adjustment do not comply with applicable law or are substantially less than prevailing commercial practices for the activities conducted by Lessee, then upon request from Lessor to Lessee, Lessee shall revise its policies to provide commercially reasonable coverage limits.

Lessee shall be named as an additional insured on such policy or policies. Lessor shall provide copies of certificates evidencing such coverage from time to time upon Lessee’s request. The limits of any insurance coverage required under this Section 15 shall be subject to adjustment as required under Subsection 14.7.

16. INDEMNITY AND RELEASE

To the fullest extent permitted by law, each Party (an “Indemnifying Party”) shall indemnify, defend and hold harmless the other Party and its consultants, owners, agents, employees, and any company of which such Party is a subsidiary or any company owned by an entity of which such Party is a subsidiary (the “Indemnified Parties”) from and against claims, damages, losses and expenses, including, but not limited to attorneys fees (collectively, “Losses”), arising out of or resulting from (a) the Indemnifying Party’s

H-15

activities or operations (i) on the Premises or (ii) which may create any liability claim against the Indemnified Parties, including, without limitation, in the case of Lessee, liens for material or labor furnished to the Premises at the instance of Lessee, except to the extent that such Losses are caused by one or more Indemnified Parties, or (b) inaccuracies in or breaches of the Indemnifying Party’s representations, warranties, covenants or agreements contained herein. Should either Party suffer a Loss because of an act or omission of the other Party, the other Party’s employees or agents, or another for whose acts the other Party is legally liable, claim shall be made in writing to the other Party within a reasonable time after such Loss occurred. Any obligation of indemnity hereunder will be limited to claims in excess of $10,000. This duty to indemnify the Indemnified Parties shall extend beyond termination of the Lease provided for in this Lease and shall continue for so long as the Indemnified Parties can be held liable for any claim or injury arising from any activities of Lessee, whether such activity occurs on the Premises or elsewhere.

16.2 Release by Lessor. LESSOR, ON ITS OWN BEHALF AND ON BEHALF OF EACH INDEMNIFIED PARTY, HEREBY IRREVOCABLY RELEASES AND DISCHARGES EACH LESSEE INDEMNIFIED PARTY FROM ANY LOSSES ATTRIBUTABLE TO (i) INTERFERENCE WITH WIND ON ANY PROPERTY OWNED IN WHOLE OR IN PART BY LESSOR THAT IS ADJACENT TO THE LEASED PROPERTY, OR (ii) AUDIBLE NOISE, ANY EFFECT OF ELECTROMAGNETIC FIELDS OR BACKGROUND STRAY VOLTAGE ON PERSONS OR LIVESTOCK ELECTROMAGNETIC NOISE OR INTERFERENCE, RADIO FREQUENCY INTERFERENCE OR CELL TOWER INTERFERENCE.

17. ASSIGNMENT AND SUBDIVISION

17.1 Assignment by the Parties. This Lease and the rights of any Party to this Lease and the Leased Property, Wind Energy Improvements, Transmission Facilities and Improvements may be assigned, encumbered, or mortgaged, in whole or in part, (and may be sublet by Lessee) without the prior written consent of the non-assigning Party, but no such assignment, encumbrance, mortgage, deed of trust, or sublease shall operate to enlarge the obligations or diminish the rights of the non-assigning Party hereto, nor relieve the assigning Party of its indemnification obligations hereunder (except as expressly provided below, with respect to the release of the assigning Party). Notwithstanding the foregoing, no assignment, encumbrance, mortgage, or sublease of this Lease or the rights of any Party hereunder or to the Leased Property, Wind Energy Improvements, Transmission Facilities or Improvements, however accomplished, shall be binding on the non-assigning Party until after the non-assigning Party has been furnished with written notice thereof and an executed original counterpart of the instrument establishing such persons’ rights under this Lease and/or to the Leased Property, Wind Energy Improvements, Transmission Facilities and Improvements. Except as otherwise provided herein, in the event of an assignment or sublease of this Lease by any Party hereto that is not for collateral or other security purposes, such Party shall be relieved of all obligations under this Lease as to the interest so assigned to the extent that such obligations relate to periods of time following such assignment and are assumed by the party to whom assigned, and liability for obligations relating to the interest so assigned and assumed and relating to the periods of time from and after such assignment shall rest exclusively upon such assignee; provided, that no such

H-16

assignment shall release the assigning Party from its removal obligations under Section 21 hereof absent a demonstration to Lessor’s reasonable satisfaction that the assignee is financially capable of assuming such obligations. Without limiting the generality of the foregoing, any such assignment shall not relieve the assigning Party from any obligation that arose or accrued prior to such assignment.

17.2 Security Assignment by Lessee; Cure Rights of Security Assignee.

17.2.1 In connection with Lessee’s financing of the Project, Lessee and every successor and assign of Lessee may, without Lessor’s prior written consent, mortgage, collaterally assign, or otherwise encumber and grant security interests in all or any part of Lessee’s rights or interests in this Lease, or any part or parts thereof, or any of the Wind Energy Improvements, Improvements or Transmission Facilities, under one or more leasehold mortgage(s), or deed(s) of trust, and may assign this Lease, or any part or parts thereof, and any subleases as collateral security for such leasehold mortgage(s), upon the condition that all rights acquired under such leasehold mortgage(s) or trustee(s) shall be subject to each and all of the covenants, conditions, and restrictions set forth in this Lease, and to all rights and interests of Lessor herein, none of which covenants, conditions, or restrictions is or shall be waived by Lessor by reason of the right given to so grant leasehold mortgages or deed(s) of trust with respect to such interest in this Lease.

17.2.2 If Lessee grants to any party (a “Security Assignee”) a Lien on or security interest in all or any part of or any interest in its rights hereunder, Wind Energy Improvements, Transmission Facilities, or Improvements for security purposes, the Security Assignee shall have no obligation or liability under this Lease prior to the time, if ever, that that such Security Assignee succeeds to the rights of the Lessee under the Lease, or to the Wind Energy Improvements, Transmission Facilities or Improvements by foreclosure or conveyance in lieu of foreclosure.

17.2.3 A Security Assignee shall have the right, but not the obligation, at any time prior to the termination or exercise of any other remedy, to pay any or all amounts due from Lessee hereunder and to do any other act or thing required of Lessee as necessary to cure any Lessee default and to prevent the termination of the Lease or the exercise of any other remedy. Security Assignee shall be entitled to a minimum of thirty (30) days to cure a monetary default if Lessee fails to cure within Lessee’s cure period, and sixty (60) days to cure a non-monetary default, if Lessee fails to cure within Lessee’s cure period; provided, further, that such period shall be extended for non-monetary defaults as reasonably necessary to effect a cure if and to the extent the same is not susceptible of cure within such sixty (60) day period but Security Assignee commences such cure within such period (or as soon as Security Assignee obtains possession of the Leased Property) and diligently prosecutes the same to completion. In furtherance of the foregoing, as a precondition to exercising any rights or remedies as a result of any alleged default by Lessee, Lessor shall give written notice of the alleged default to each Security Assignee of which Lessor has received notice concurrently with delivery of such notice to Lessee, specifying in detail the alleged default and not less than thirty (30) days prior written notice of the date Lessor (subject to the notice provision set forth in Section 18.2) will commence the exercise of termination or any other remedy under this Lease. Upon any payment or cure by Security Assignee provided for in this Section 17.2.3, Security Assignee shall be

H-17

subrogated to the rights of the Lessor in respect of the defaulted payment and interest payable thereon and shall be entitled to receive such defaulted payment and interest as shall be provided in the agreement or other instrument granting the Security Assignee a Lien or security interest in all or any part of or interest in this Lease, the Leased Property, the Wind Energy Improvement, Transmission Facilities or Improvements or as shall be provided in any other agreement between the Lessee and the Security Assignee, and Lessor shall not be entitled to terminate this Lease and any notice of termination or breach previously given shall be void.

17.2.4 There shall be no voluntary cancellation, surrender or amendment to this Lease by joint action of Lessor and Lessee without the prior written consent of the Secured Assignee.

17.2.5 Lessor shall execute any instruments that a Secured Party may reasonably request with respect to acknowledging (i) the right of Lessee or its assignee or sublessee to erect or install the Improvements, and that same shall not be deemed to be nor become part of the Premises, (ii) the right of the Secured Party to maintain a lien or security interest in the Improvements superior to any claim or interest of Lessor, and (iii) the right to remove any or all Improvements in the event of default in the instrument creating the lien or security interest, subject to the terms hereof regarding remediation of the Premises.

17.3 New Lease. If this Lease is rejected by a trustee or debtor-in-possession in any bankruptcy or insolvency preceding except in the case where Lessee shall elect to retain its rights under the Lease pursuant to Section 365(h) of the U.S. Bankruptcy Code or other similar applicable law, or the Lease is terminated by operation of law or as a result of any default, and within one hundred twenty (120) days after such rejection or termination a Security Assignee shall have arranged to the reasonable satisfaction of Lessor for the payment of all fees or other charges due and payable by Lessee as of the date of such rejection or termination, then Lessor shall execute and deliver to Security Assignee or its designee a new lease to the Leased Property which (a) shall be for a term equal to the remainder of the term of the Lease before giving effect to such rejection or termination, (b) shall contain the same covenants, agreements, terms, provisions and limitations as this Lease (except for any requirements that have been fulfilled by Lessee prior to rejection or termination of the Lease), (c) shall include that portion of the Lease, Leased Property, Wind Energy Improvements or Improvements in which Security Assignee had a security interest on the date of rejection or termination, (d) shall enjoy the same priority as this Lease over any Lien or other interest created by Lessor, (e) may be made subject to the same security interest held by Security Assignee prior to any such rejection by a trustee or debtor-in possession in any bankruptcy or insolvency proceeding; and, until such time as such new lease is executed and delivered, the Security Assignee may enter, use and enjoy the Leased Property and conduct operations thereon as if this Lease were still in effect.

17.4 Third Party Beneficiary. For purposes of enforcing it rights and remedies and the obligations of the Lessor and the Lessee under this Lease, Security Assignee shall be an express third party beneficiary thereof and may enforce such rights and remedies and such obligations of the Lessor and Lessee.

H-18

17.5 Subdivision/Separation. In order to satisfy the financing and transactional requirements of the separate Lenders and power purchasers of each Wind Energy Improvement, the Lessee may, upon prior written notice to Lessor and subject to applicable law, (i) subdivide the leasehold estate and all rights and obligations of Lessee granted hereby into separate leasehold estates (the “Subdivided Leaseholds”), referencing specific portions of the Premises to be included in each Subdivided Leasehold; and (ii) assign each Subdivided Leasehold to a single purpose limited liability company or legal entity that will own the Wind Energy Improvement located within the Subdivided Leasehold. In lieu of such subdivisions, at the request of Lessee, Lessor and Lessee will (i) amend this Lease to remove portions of the Leased Property other than that required for the initial Wind Energy Improvement; and (ii) cause Lessor and any designee of Lessee to execute one or more separate leases with respect to such removed portions of the Leased Property, each in form and substance materially identical to this Lease (with such changes as shall be necessary to reflect such removal). In order to comply with the separate financial and security requirements of separate Wind Energy Improvements, the segregated leasehold estates will not be subject to cross defaults with each other, allowing each lessee and its Security Assignees to enjoy quiet title to their respective leasehold rights and interests regardless of any default of another lessee.

18. DEFAULT AND TERMINATION

18.1 Lessee’s Right to Terminate. In addition to its other termination rights herein, Lessee shall have the right to terminate the Lease as to all or any part of the Leased Property at any time, effective upon thirty (30) days’ written notice to Lessor from Lessee.

18.2 Lessor’s Right to Terminate. Subject to Section 17.2.3, Lessor shall have the right to terminate the Lease if (a) a material default in the performance of Lessee’s obligations under this Lease shall have occurred and remains uncured, (b) Lessor notifies Lessee and Security Assignee in writing of the default, which notice sets forth in reasonable detail the facts pertaining to the default, and (c)(i) if the default is a failure to pay undisputed charges or sums due and payable, then if the default, shall not have been remedied within sixty (60) days after Lessee and Security Assignee receive notice thereof, or (ii) if the default is other than a payment default described in clause (c)(i), then if the default shall not have been remedied within one hundred twenty (120) days after Lessee and Security Assignee receive notice thereof, or if the default will take longer than one hundred twenty (120) days for Lessee to remedy, Lessee is not working diligently to remedy such default.

18.3 Effect of Termination. Upon termination of the Lease, whether as to the entire Leased Property or a portion thereof, Lessee shall, upon written request by Lessor, prepare and place of record in the county or counties in which the Leased Property is located, a release of all of Lessee’s right, title and interest in and to the Leased Property, or to that part thereof as to which the Lease has been terminated. Subject to Section 21, following termination of the Lease as to all or any part of the Leased Property, Lessee shall peaceably and quietly leave, surrender and return the Leased Property (or applicable portion thereof) to Lessor. All further rights and obligations of Lessor and Lessee under this Lease will cease and terminate as of the date of any termination with respect or in regard to the Leased Property, or to that part as to which the Lease has been terminated; except for the provisions of Section 21 and those obligations that expressly survive the termination of this Lease.

H-19

18.4 Remedies. If either Lessor or Lessee breaches this Lease, the non-breaching Party shall have all rights and remedies available to such non-breaching Party at law and in equity. In consideration of the investment being made by Lessee in reliance on the provisions herein, including Sections 3 and 4 hereto regarding coordination of Lessor and Lessee activities on the Premises, Lessee shall have the special remedy of specific enforcement with respect to Lessor breaches of this Lease that adversely affect the operation of any Wind Energy Improvement. In order to protect its investment in future agricultural installations, Lessor shall have the special remedy of specific performance with respect to the bio-security provisions set forth in Section 12.7.

18.5 Safety Risks/Emergency. Notwithstanding any other term hereof, each Party may undertake such actions as may be reasonable under the circumstances to avoid imminent death, injury or damage to the persons or property of themselves or others, without incurring liability hereunder or to avoid violation of any federal, state, or local government, agency, or other authority under any applicable federal, state, or local law, rule, regulation, ordinance, statute, order, or decree. Lessor may undertake any action it deems necessary under the circumstances to cure a breach by Lessee of Lessor’s Bio-Security Management System or Animal Welfare System requirements, and Lessee shall reimburse Lessor the reasonable cost of any such cure.

19. CONDEMNATION.

19.1 Complete Taking. If during the Initial Term or any extension thereof there shall be taken for any public or quasi-public use under any statute or by right of eminent domain or by private purchase in lieu thereof, the entire Leased Property or any substantial portion of the Leased Property which is sufficient to render the remaining portion thereof unsuitable, in the sole judgment of Lessee, for restoration for continued use by Lessee for the purposes of this Lease, Lessee shall have the right to terminate this Lease as of the date of such taking. Such termination shall be without prejudice to the rights of either Lessor or Lessee to recover compensation from the condemning authority for any Loss caused by such condemnation.

19.2 Partial Taking. If during the Term there shall be taken for any public or quasi-public use under any statute or by right of eminent domain or by private purchase in lieu thereof, a portion of the Leased Property which is not sufficient to require termination of this Lease as provided in Section 19.1 above, then this Lease shall continue in full effect as to the untaken portion notwithstanding such taking, and the rent payable hereunder shall be equitably adjusted based on the circumstances. In the event of any lesser taking as described in this Section 19.2, Lessee shall be entitled to the portion of the net award for such taking (whether paid by way of damages, rent or otherwise) allocable to the Improvements placed on the Leased Property by Lessee, or to the relocation of the same.

19.3 Apportionment, Distribution of Award. On any taking, all sums awarded shall be apportioned between the Parties in proportion to their respective: (i) costs of relocating or removing property; (ii) anticipated lost revenues or profits; (iii) other remaining values of their respective interests.

H-20

20. RIGHTS UPON SALE. If Lessor desires during the Initial Term or any extension thereof to sell, transfer or otherwise dispose (a “Sale”) of all or any portion of its interest in the Leased Property to a third party (“Purchaser”), Lessor shall (a) obtain from the Purchaser a bona fide written offer to acquire such interest, stating the terms and conditions upon which the Sale is to be made and the consideration offered therefore, and (b) give written notification to Lessee of its intention to so sell or otherwise dispose of its interest in the Leased Property, which notification shall be accompanied by a copy of Purchaser’s offer. Lessee shall have the option to purchase all but not less than all of the interest in the Leased Property offered by Lessor upon the same terms and conditions as offered by the Purchaser, which option may be exercised by giving written notification to Lessor within twenty (20) days after notice of Lessor’s intent to sell or otherwise dispose of the interest in the Leased Property. If Lessee fails to timely exercise its purchase option, Lessor shall be entitled to consummate the Sale to the Purchaser upon terms and conditions that are materially no less favorable than are set forth in Purchaser’s offer, with such Purchaser taking subject to this Lease. If Lessee timely elects to exercise its purchase option, it shall designate the time, date, and place of closing, provided that the date of closing shall be within sixty (60) days of the date of Lessee’s exercise of its purchase option.

21. REMOVAL UPON TERMINATION. Upon termination of the Lease, Lessee shall, within ninety (90) days, remove its building(s), equipment, cables, fixtures, and all personal property and otherwise restore the Premises, reasonable wear and tear and casualty excepted, it being understood that WTG foundations shall be removed to at least five feet (5’) below grade and covered with topsoil, and at the request of Lessor, any access roads and crane pads will be contoured to match the surrounding terrain and seeded. Lessor agrees and acknowledges that all of the Improvements, equipment, fixtures and personal property of Lessee shall remain the property of Lessee, and Lessee shall have the right to remove the same, whether or not said items are considered fixtures and attachments to real property under applicable law. If such time for removal causes Lessee to remain on the Premises after the 90th day following termination of this Lease, Lessee shall pay Base Rent at the then existing monthly rate until such time as the removal of the building(s), equipment, cables, fixtures and all personal property are completed. Lessee shall be responsible to remove any hazardous materials or environmental contamination from the Premises that it caused to be located thereon.

22. MISCELLANEOUS

22.1 Force Majeure. If performance of this Lease or of any obligation hereunder (other than an obligation to pay any amounts described in Section 10) is prevented or substantially restricted or interfered with by reason of an event of Force Majeure (defined below), the affected Party shall be excused from such performance to the extent of and for the duration of such prevention, restriction, or interference. The affected Party shall promptly notify the other Party in writing of the event of Force Majeure and shall use its reasonable efforts to avoid or remove such causes of nonperformance, and shall continue performance hereunder whenever such causes are removed. The term “Force Majeure” means causes beyond the reasonable control of and without the fault or negligence of the Party claiming Force Majeure, including, but not limited to, acts of God, labor unrest (including, but not limited to, slowdowns, picketing, boycotts or strikes), floods, earthquakes, storms, fires, lightning, explosions, power failures or power surges, vandalism, theft, terrorism, the unauthorized cutting of power, transmission or other lines, wires or cables to a Wind Energy Improvement, epidemics, wars,

H-21

revolutions, riots, civil disturbances, sabotage, changes in law or applicable regulations subsequent to the date hereof and actions or inactions by any federal, state or local legislative, executive, administrative judicial agency or body which in any of the foregoing cases, by exercise of due foresight such Party could not reasonably have expected to avoid, and which, by the exercise of due diligence, it is unable to overcome.

22.2 Exclusion of Warranties. Lessor and Lessee specifically acknowledge that Lessee is responsible to evaluate the condition and suitability of the Leased Property for use by Lessee for the purposes set out in this Lease. LESSOR EXPRESSLY EXCLUDES ANY WARRANTY THAT THE PREMISES OR ANY IMPROVEMENTS OR EQUIPMENT LOCATED ON THE PREMISES ARE SUITABLE OR FIT FOR LESSEE’S USE FOR THE PURPOSES INTENDED BY LESSEE OR FOR ANY PURPOSE.

22.3 Further Assurances. Each Party shall, whenever reasonably requested by the other, execute, acknowledge and deliver, or cause to be executed, acknowledged and delivered, all conveyances, assignments and all other instruments and documents as may be reasonably necessary in order to complete the transactions herein provided and to carry out the terms and provisions of this Lease.

22.4 Severability. If, at any time, any provision of this Lease is or becomes illegal, invalid, or unenforceable in any respect under the law of any jurisdiction, neither the legality, validity, or enforceability of the remaining provisions hereof nor shall the legality, validity, or enforceability of such provision under the law of any other jurisdiction in any way be affected or impaired thereby and the Parties shall promptly negotiate to restore this Lease as near as possible to its original intent and economic effect.

22.5 Tax Credits. Lessee and Lessor acknowledge and agree that as between Lessee and Lessor, Lessee is, to the extent allowed by law, to have the benefit of all federal, state, and local tax credits and other benefits associated with the generation of electricity from a “clean” or renewable power source. Except as provided above, if under applicable law the holder of a leasehold interest becomes ineligible for any tax credit, benefit, or incentive for alternative energy expenditure established by any local, state, or federal government, then, at Lessee’s option, Lessor and Lessee, to the extent practicable, shall amend this Lease or replace it with a different instrument, so as to convert Lessee’s interest in the Leased Property to a substantially equivalent interest that makes Lessee eligible for such tax credit, benefit, or incentive; provided, however, that any such change shall not materially reduce Lessor’s rights or benefits hereunder.

22.6 No Partnership. Nothing contained in this Lease shall be construed to create a partnership or joint venture between the Parties or their successors in interest and Lessor shall not have any ownership in the Wind Energy Improvements or any rights to the electricity generated thereby except and to the extent set forth in a written agreement by and between Lessor and Lessee.

22.7 Construction. The Parties acknowledge that their attorneys have reviewed and revised this Lease and that any rule of construction to the effect that any ambiguities are to be resolved against the drafting Party shall not be employed in the interpretation of this Lease or

H-22

any amendments or exhibits hereto. Each Party was represented by legal counsel in the negotiations of this Lease.

22.8 Counterparts. This Lease may be executed by facsimile [provided that a duplicate copy with an original signature is transmitted to the other Party within the following ten (10) days] and in multiple counterparts, no one of which need be executed by all Parties hereto, each of which shall constitute an original. Counterparts thus executed shall together constitute one and the same instrument.

22.9 Integration. This Lease contains all agreements, promises and understandings between the Lessor and the Lessee and that no verbal or oral agreements, promises or understandings shall be binding upon either the Lessor or the Lessee in any dispute, controversy or proceeding at law, and any addition, variation or modification to this Lease shall be void and ineffective unless made in writing and signed by the Parties. This Lease supersedes in all respects that certain Option Agreement between the Parties hereto, dated October 8, 2003, as subsequently amended on April 15, 2005 and April 1, 2006, and such Option Agreement is of no further effect.

22.10 Governing Law. This Lease and the performance thereof shall be governed, interpreted, construed and regulated in accordance with the laws of the State of Utah.

22.11 Notices. All notices hereunder must be in writing and shall be deemed validly given if sent by certified mail, return receipt requested, or by commercial courier, provided the courier’s regular business is delivery service and provided further that it guarantees delivery to the addressee by the end of the next business day following the courier’s receipt from the sender, addressed as follows (or any other address that the Party to be notified may have designated to the sender by like notice):

22.12 Successors. This Lease shall extend to and bind the heirs, personal representatives, successors, trustees, and assigns of the Parties hereto.

22.13 Recording. Concurrent with the execution of this Lease, the Parties shall each execute and acknowledge an amended and restated memorandum to replace and supersede the Original Memorandum and either Party may thereafter record such amended and restated memorandum in the Official Records of the Millard County Recorder and the Beaver County Recorder. The date set forth in any such amended and restated memorandum is for recording purposes only and bears no reference to commencement of either term or rent payments.

22.14 Casualty. In the event of damage by fire or other casualty whatsoever to the Leased Property that cannot reasonably be expected to be repaired within forty-five (45) days following same or, if the Premises is damaged by fire or other casualty whatsoever so that such damage may reasonably be expected to disrupt the Lessee’s operations at the Premises for more than forty-five (45) days, or if any event makes it impossible for the Lessee to effectively and practicably operate Lessee’s business at a reasonable profit as determined by Lessee, then the Lessee may at any time following such fire or other casualty or event, terminate this Lease upon sixty (60) days written notice to the Lessor. Any such notice of termination shall cause this Lease to expire with the same force and effect as though the date set forth in such notice were the date originally set as the expiration date of this Lease, and the Parties shall make an appropriate adjustment, as of such termination date, with respect to payments due to the other under this Lease.

22.15 Submission of Lease. The submission of this Lease for examination does not constitute an offer to lease the Premises, and this Lease becomes effective only upon the full execution of this Lease by the Parties.

22.16 Authority to Execute Agreement. Each of the Parties hereto warrants to the other that the person or persons executing this Lease on behalf of such Party has the full right, power and authority to enter into and execute this Lease on such Party’s behalf and that no consent from any other person or entity is necessary as a condition precedent to the legal effect of this Lease.

22.17 Applicable Legal Requirements. The Lessee shall use the Leased Property as may be required or as permitted by applicable Legal Requirements. The Lessee agrees to keep the Leased Property in material conformance with all applicable Legal Requirements and agrees to reasonably cooperate with the Lessor regarding any compliance required by the Lessor in respect to its use of the Premises.

22.18 Arbitration.

22.18.1 Any claim shall, at the request of either Party, be referred to a senior representative of each of the Parties for resolution on an informal basis as promptly as

H-24

practicable. If the senior representatives are unable to resolve the dispute within thirty (30) calendar days of such referral or such other period as the Parties may mutually agree, the Parties may submit the matter to binding arbitration in accordance with this Section 22.18.

22.18.2 Any controversy arising out of or relating to this Lease, including but not limited to the interpretation of the Lease, may be subject to arbitration upon the mutual agreement of the Parties. Should the Parties elect to proceed with arbitration, an award shall be final and judgment may be entered on the award. All Parties to this Lease are bound, each to the other, by this arbitration clause, provided that each such Party has signed this Lease or has signed another agreement or document that incorporates this Lease by reference, or signs any other agreement to be bound by this arbitration clause.

22.18.3 The Parties hereto agree to be bound by the Utah Uniform Arbitration Act, Utah Code Ann. §§ 78-31a-101, et seq., or any subsequent recodification or enactment of a replacement to these provisions. The arbitrators shall apply Utah law in evaluating the evidence presented.

Should any Party refuse or neglect to appear or participate in the arbitration proceedings after due notice, the arbitrator or arbitrators are empowered to decide the controversy in accordance with whatever evidence is presented ex parte. Each side shall bear its own costs and attorney fees incurred for the time, expense, and trouble of the arbitration. The costs and fees associated with pursuing the arbitration with the American Arbitration Association shall be borne equally by all the Parties.

22.18.5 This Section 22.18 shall survive the termination or expiration of this lease.

22.18.6 Judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction.

22.19 Captions. The captions contained in this Lease are inserted for convenience only and are not intended to be part of this Lease. They shall not affect or be utilized in the construction or interpretation of this Lease.

22.20 Publicity. Neither Party shall use the name, trademark, logo, or other identifying information of the other Party or its affiliates in any publicity display or advertising without the other Party’s prior written approval.

22.21 Survival. Any provision of this Lease that expressly or by implication comes into or remains in force following the termination of this Lease shall survive the termination or expiration of this Lease for the period set forth in such provision, or if no period is set forth in such provision, for the period that is coextensive with the applicable statute of limitations. The provisions of the Lease relating to indemnification from one Party to the other

H-25
