Execution Version

or described on such a Disclosure Schedule or that is necessary to complete or correct any information in any representation or warranty contained in Article XVII (a “Disclosure Schedule Update”); provided, that (a) the facts, events or circumstances disclosed in such amendment or supplement could not reasonably be expected to have a Material Adverse Effect and (b) if such facts, events or circumstances result from a breach of this Agreement by the amending or supplementing Party or its negligence, willful misconduct or fraud, such Party shall indemnify the other Parties and their respective Indemnified Persons for all Claims in connection with such facts, events or circumstances.

Within twenty (20) Business Days after its receipt of NPC’s draft allocation of the NPC Purchase Price and SPPC Purchase Price, Great Basin shall propose to NPC any changes thereto or otherwise NPC’s draft allocation shall be deemed to have agreed thereto. If Great Basin proposes changes to NPC’s proposed allocation of the NPC Purchase Price or SPPC Purchase Price within such twenty (20) Business Day period described above, NPC and Great Basin shall cooperate in good faith to mutually agree upon a revised allocation as soon as practicable (such allocation of the NPC Purchase Price and the SPPC Purchase Price, as finally agreed to by the Parties, the “Allocation”). If the Parties cannot agree upon the legal basis on which NPC has made the Allocation within sixty (60) days after delivery of such proposed changes (if any), NPC shall secure a legal opinion of a nationally recognized tax counsel that the basis on which NPC made such proposed Allocation is more likely than not correct. If NPC secures such opinion, then the Allocation shall be made on the legal basis proposed by NPC, and Great Basin shall pay all reasonable costs associated with such legal opinion. If NPC fails to secure such opinion, then NPC shall be responsible for the costs of such opinion, and Great Basin shall then secure a legal opinion of a nationally recognized tax counsel that the basis on which Great Basin made such proposed Allocation is more likely than not correct. If Great Basin secures such opinion, then the Allocation shall be made on the legal basis proposed by Great Basin, and NPC shall pay all reasonable costs associated with such legal opinion. If Great Basin fails to secure such opinion, then Great Basin shall be responsible for the costs of such opinion, and then the Parties shall work together to secure a tax opinion that supports a proposed Allocation. If the Parties cannot agree upon the valuations in the Allocation within thirty (30) days after delivery of such proposed changes (if any), the Parties shall mutually select the Independent Auditor or another external auditor or appraiser, as determined based on the nature of the valuation dispute, which shall be instructed to resolve such disagreement within thirty (30) days after such disagreement is submitted to it for resolution and shall notify Great Basin and NPC in writing of its resolution.

cause their Affiliates to, report, act, and file all Tax returns, forms or reports in all respects and for all purposes consistent with the Allocation. No Party shall take any position (whether in audit, Tax returns, or otherwise or with any Governmental Authority) that is inconsistent with the Allocation except as may be adjusted by subsequent written agreement following an audit by the Internal Revenue Service or by court decision.

ARTICLE III

OWNERSHIP AND CAPACITY RIGHTS; MONTHLY PAYMENT

3.01 Ownership Rights.

(a) ON Line Ownership; Waiver of Partition Rights. After the Acquisition Closing Date, the Parties shall own ON Line as tenants-in-common with each Party owning an Ownership Interest in the amount of its Ownership Percentage. The Parties recognize that the physical partition of ON Line or any part thereof, whether by partition in kind or sale and division of the proceeds thereof, would be impossible and impractical and wholly inconsistent with the purposes for which this Agreement is made. As such, each Party agrees that it shall not take any action at any time by judicial proceedings, arbitration or otherwise, to partition ON Line or any part thereof, in any way, whether by partition in kind or by sale and division of the proceeds thereof. Each Party further irrevocably waives the right of partition and the benefit of all statutory or common law that may now or hereafter authorize such partition of ON Line or any part thereof. In the event any such right of partition shall hereafter accrue, each Party shall from time to time upon the written request of any other Party execute and deliver such further instruments as may be necessary to confirm the foregoing waiver and release of its right to partition. The Parties shall amend this Agreement to update Annex A upon any change in Ownership Percentages pursuant to the terms hereof such that, at any time, Annex A accurately reflects each Party’s Ownership Percentage.

(b) After-Acquired ON Line Property and Rights. Unless otherwise determined by the Parties, any Party which acquires in its own name, or an Affiliate’s name, an interest in any real or personal property (whether tangible or intangible), contractual right or any other asset that is part of ON Line shall acquire and hold the same subject in all respects to this Agreement and for the benefit of the Parties in proportion to their respective Ownership Percentages, and subject to Section 3.01(c), any such Party shall transfer and assign an ownership interest therein to the other Parties equal to such other Parties’ respective Ownership Percentages (a) within fifteen (15) days after such acquisition and (b) at the Acquisition Closing, whichever occurs later, and do all things necessary or appropriate to register or record on any appropriate register the property in the names of the Parties.

(c) ON Line Agreements and Governmental Approvals. Except as otherwise agreed by the Management Committee, all ON Line Agreements entered into after the Acquisition Closing Date shall be in the name of Great Basin and NPC and Governmental Approvals for ON Line applied for after the Acquisition Closing Date shall be in the name of the Parties and the Parties shall use their commercially reasonable efforts to ensure that all ON Line Agreements shall allow for assignment, without consent, to Persons holding an Ownership Interest. Unless otherwise agreed by the Parties, each ON Line Agreement shall expressly provide that, after the Acquisition Closing Date, the obligations and undertakings of the Parties

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

thereunder are several and not joint and that each Party is and shall be liable and responsible only for its Ownership Percentage of such obligations and undertakings; provided, however, that, with respect to any ON Line Agreement to which SPPC is not a party and, as between NPC and SPPC, NPC shall be liable to any counterparty (other than Great Basin) under any such ON Line Agreement for SPPC’s Ownership Percentage of obligations and undertakings under any such ON Line Agreement, and NPC shall provide SPPC with the benefit of five percent (5%) of its rights under any such ON Line Agreement and SPPC shall promptly reimburse NPC for five percent (5%) of any liability or obligation incurred by NPC under any such ON Line Agreement. If required by a counterparty (other than a Party) under an ON Line Agreement, the Parties shall use commercially reasonable efforts to provide credit support in a form acceptable to such counterparty, such that the Parties’ obligations under such ON Line Agreement are several and not joint.

(d) Great Basin Segment Ownership. Great Basin shall (i) own one hundred percent (100%) of the ownership interests in the Great Basin Segments and (ii) be solely responsible for the development, construction, ownership, management and maintenance of the Great Basin Segments and all costs and liabilities related to development, construction, ownership, management, operation and maintenance of the Great Basin Segments, including all Great Basin O&M Costs and the costs of any Transmission Improvements as provided in Section 6.01; provided, however, that, while the Parties, as of the Effective Date, expect that the Great Basin Segments will be fully developed and constructed, nothing contained in this Agreement (other than Great Basin’s obligation set forth in Section 3.02(b)) shall be construed to obligate Great Basin or any of its Affiliates to complete the development and/or construction of the Great Basin Segments (or any portion thereof), such decision being in the sole discretion of Great Basin and its Affiliates.

3.02 Electrical Capacity Rights.

(a) Prior to the Commercial Operation of Either Great Basin Segment. During the period commencing immediately after the Acquisition Closing Date to the date of commercial operation of the first Great Basin Segment to achieve commercial operation, the NVE Parties’ Capacity Entitlement shall be one hundred percent (100%). For the avoidance of doubt, Great Basin shall not be entitled to any Electrical Capacity after the Acquisition Closing Date and prior to the date of commercial operation of the first Great Basin Segment to achieve commercial operation.

(b) Prior to GB Segment COD. During the period commencing on the date of commercial operation of the first Great Basin Segment to achieve commercial operation to GB Segment COD, the NVE Parties’ Capacity Entitlement shall be as follows (and Great Basin’s Capacity Entitlement shall be all remaining Electrical Capacity):

(i) If SWIP-N is the first Great Basin Segment to achieve commercial operation, the NVE Parties’ Capacity Entitlement shall be forty-five and two tenths percent (45.2%) of the electrical Capacity; and

Privileged and Confidential

Execution Version

(ii) If SNIP is the first Great Basin Segment to achieve commercial operation, the NVE Parties’ Capacity Entitlement shall be seventy and four tenths percent (70.4%) of the Electrical Capacity.

If Great Basin achieves commercial operation of one of the Great Basin Segments but is prevented from achieving GB Segment COD as a result of a Force Majeure event that is reasonably expected to prevent continued progress on the Great Basin Segment that has not achieved commercial operation for more than two hundred forty (240) days and, as a result, Great Basin suspends performance under all material construction contracts associated with such Great Basin Segment pending resolution of the Force Majeure event, then for the period extending from the commencement of the Force Majeure event to the third (3rd) anniversary thereof, Great Basin shall use commercially reasonable efforts to overcome the Force Majeure event and achieve GB Segment COD as expeditiously as possible. Notwithstanding Sections 3.02(b)(i) and (ii), during the period extending from such two hundred fortieth (240th) day to GB Segment COD, Great Basin’s Capacity Entitlement shall be determined in accordance with the following formula (and the NVE Parties’ Capacity Entitlement shall be all remaining Electrical Capacity):

Capacity Entitlement = (AI Comm + [AI Not Comm * % Comp] - DC) / AI Total

Where:

AI Comm = the Anticipated Investment of the Great Basin Segment that has achieved commercial operation;

AI Not Comm = the Anticipated Investment of the Great Basin Segment that has not achieved commercial operation;

% Comp = the aggregate percentage complete of the construction of the Great Basin Segment that has not achieved commercial operation at the time of the suspension of work, as reasonably determined by the Parties; and

AI Total = the sum of (i) the Anticipated Investment of the Great Basin Segment that has achieved commercial operation, (ii) the Anticipated Investment for ON Line and (iii) AI Not Comm * % Comp; and

DC = to the extent the Parties consummate the SNIP Option Closing, the amount set forth in Section 6.05(b)(iv)(2)(B).

(c) Following GB Segment COD. From and after the GB Segment COD, the Parties shall be entitled to Electrical Capacity as follows:

(i) If the Electrical Capacity of the Transmission Line is equal to or less than 2,000 MW, then the NVE Parties’ Capacity Entitlement shall be thirty-eight percent (38%) of such Electrical Capacity and Great Basin’s Capacity Entitlement shall be all Electrical Capacity other than the Electrical Capacity to which the NVE Parties are entitled.

(ii) If the Electrical Capacity of the Transmission Line is greater than 2,000 MW but equal to or less than 2,080 MW, then the NVE Parties’ Capacity Entitlement shall be thirty-eight percent (38%) of 2,000 MW of such Electrical Capacity and one hundred percent (100%) of all Electrical Capacity in excess of 2,000 MW, and Great Basin’s Capacity Entitlement shall be all Electrical Capacity other than the Electrical Capacity to which the NVE Parties are entitled.

(iii) If the Electrical Capacity of the Transmission Line is greater than 2,080 MW but equal to or less than 2,100 MW, then the NVE Parties’ Capacity Entitlement shall be thirty-eight percent (38%) of 2,000 MW of such Electrical Capacity and one hundred percent (100%) of 80 MW of such Electrical Capacity, and Great Basin’s Capacity Entitlement shall be all Electrical Capacity other than the Electrical Capacity to which the NVE Parties are entitled.

(iv) If the Electrical Capacity of the Transmission Line is greater than 2,100 MW, then the NVE Parties’ Capacity Entitlement shall be thirty-eight percent (38%) of 2,000 MW of such Electrical Capacity, one hundred percent (100%) of 80 MW of such Electrical Capacity and thirty-eight percent (38%) of all Electrical Capacity in excess of 2,100 MW, and Great Basin’s Capacity Entitlement shall be all Electrical Capacity other than the Electrical Capacity to which the NVE Parties are entitled.

(d) Unavailability of Transmission Line. Notwithstanding Sections 3.02(b) or (c):

(i) if after commercial operation of a Great Basin Segment but prior to GB Segment COD, such Great Basin Segment becomes unavailable (A) for a period in excess of one hundred twenty (120) consecutive days, due to Force Majeure, an Event of Loss, Condemnation Action or any change in Applicable Law commencing after such one hundred twentieth (120th) day, and (B) commencing immediately, due to any negligent act or omission or any Willful Misconduct/Gross Negligence of or breach of this Agreement by Great Basin, then from such date to the date the unavailable Great Basin Segment again becomes available, the NVE Parties’ Capacity Entitlement shall be one-hundred percent (100%) of the Electrical Capacity.

(ii) if after commercial operation of a Great Basin Segment, ON Line becomes unavailable (A) for a period in excess of one hundred twenty (120) consecutive days, due to Force Majeure, an Event of Loss, Condemnation Action or any change in Applicable Law commencing after such one hundred twentieth (120th) day, and (B) commencing immediately, due to any negligent act or omission or any Willful Misconduct/Gross Negligence of or breach of this Agreement by the NVE Parties, in each case unless such availability is caused by the withholding by Great Basin (including any of Great Basin’s Authorized Representatives) of any consent to any action proposed by NPC in good faith, consistent with Prudent Utility Practices and not in violation of any Applicable Law and for which the NVE Parties are obligated to fund all costs thereof under this Agreement directly or through an adjustment to the Monthly Payment, then from such date to the date ON Line again becomes available, Great

Incremental Cost Differential Component = (the Incremental Cost Differential funded by Great Basin / applicable Amortization Period) + interest accruing during such month on any unamortized portion of the Incremental Cost Differential at a rate equal to the NVE WACC as of ON Line COD with the return on equity component discounted by seventy-five (75) basis points;

Capital Repair Component = the aggregate sum of the following calculated in respect of each Capital Repair: (the applicable Net Capital Repair Cost funded by Great Basin / applicable Amortization Period) + interest accruing during such month on any unamortized portion of such Net Capital Repair Cost at a rate equal to the NVE WACC as of the time of the relevant Capital Repair Cost was incurred with the return on equity component discounted by fifty (50) basis points;

Event of Loss Component = the aggregate sum of the following calculated in respect of each Event of Loss: (the applicable Net Event of Loss Cost funded by Great Basin / applicable Amortization Period) + interest accruing during such month on any unamortized portion of such Net Event of Loss Costs at a rate equal to the NVE WACC as of the time of the relevant Event of Loss Cost was incurred with the return on equity component discounted by fifty (50) basis points; and

Condemnation Action Component = the aggregate sum of the following calculated in respect of each Condemnation Action: (the applicable Net Condemnation Action Cost funded by Great Basin / applicable Amortization Period) + interest accruing during such month on any unamortized portion of such Net Condemnation Action Cost at a rate equal to the NVE WACC as of the time of the relevant Condemnation Action Cost was incurred with the return on equity component discounted by fifty (50) basis points.

Great Basin shall deliver an invoice by the tenth (10th) day of each month during the Monthly Payment Period setting the Monthly Payment owed for such month along with reasonable supporting documentation, and on the last Business Day of each month (but extended by a day for each day that the invoice is late) during the Monthly Payment Period, NPC shall pay ninety-five percent (95%) of the undisputed portions of the Monthly Payment to Great Basin and SPPC shall pay five percent (5%) of the undisputed portions of the Monthly Payment to Great Basin.

(b) The Monthly Payment shall be proportionally reduced: (i) to the extent ON Line becomes unavailable to one or both of the NVE Parties for a period in excess of one hundred twenty (120) consecutive days due to Force Majeure, an Event of Loss, Condemnation Action or any change in Applicable Law commencing after such one hundred twentieth (120th) day, and (ii) commencing immediately, to the extent that ON Line becomes unavailable to one or both of the NVE Parties due to (A) any negligent act or omission or any Willful Misconduct/Gross Negligence of, or breach of this Agreement by, Great Basin or (B) unless the Management Committees agrees to alternative action, the withholding by Great Basin (including any of Great Basin’s Authorized Representatives) of any consent to any action proposed by NPC in good faith, consistent with Prudent Utility Practices and not in violation of any Applicable Law and for which the NVE Parties are obligated to fund all costs thereof under

this Agreement directly or through an adjustment to the Monthly Payment. In the event, during any calendar month, ON Line has become unavailable to one or both of the NVE Parties under the circumstances described in clauses (i) and (ii) above, the Monthly Payment payable at the end of such month shall be adjusted to reflect the number of hours during which ON Line was so unavailable to one or both of the NVE Parties as compared to the number of hours in such month (it being understood that, if ON Line becomes unavailable to only one of the NVE Parties, the other NVE Party shall continue to be obligated to pay its portion of the Monthly Payment). For the avoidance of doubt, for any given calendar month, the Monthly Payment in respect of such month shall not be due and payable, and shall be forever waived in its entirety, if ON Line is completely unavailable for the entire month for any reason described in clauses (i) or (ii) above.

(c) NPC’s and SPPC’s obligation to pay its portion of the Monthly Payment shall cease upon (i) consummation of any purchase by the NVE Parties (or any one of them individually) of all of Great Basin’s Ownership Interests or (ii) the effectiveness of a notice terminating the Terminated Capacity as set forth in Section 16.02(h). The Monthly Payment shall not be subject to escalation or other adjustment (including following GB Segment COD), except as expressly set forth herein.

3.07 Great Basin Segment Abandonment or Delay Buyout Right.

(a) If Great Basin (i) has not achieved GB Segment Financial Closing on or before the GB Segment Financial Closing Deadline, (ii) ceases development or construction of any Great Basin Segment for a period of ninety (90) consecutive days at any time and expresses its intent in writing or makes a public announcement of its intent not to complete development or construction of any Great Basin Segment or (iii) has not achieved GB Segment COD before GB Segment COD Deadline, and, as of the GB Segment COD Deadline, either of the following is true: Great Basin (A) does not have financing arrangements available to achieve GB Segment COD and complete construction of the Great Basin Segments or (B) is not actively constructing the Great Basin Segments, in each case, for reasons other than a pending formal proceeding challenging the Great Basin Segments or any Governmental Approvals for the Great Basin Segments, for any other event of Force Majeure or as a result of an Event of Default by a NVE Party, then the NVE Parties shall have the right to purchase all (but not less than all) of Great Basin’s Ownership Interests for a price determined in accordance with Schedule 5; provided that written notice of their election to exercise such right is provided to Great Basin by the fourteenth (14th) anniversary of the ON Line COD. If such purchase right arises and the NVE Parties timely elect to exercise such right, then Great Basin shall Transfer all of its Ownership Interests to the NVE Parties free and clear of any Liens other than Permitted Liens upon the latest to occur of (i) the fifteenth (15th) anniversary of the ON Line COD, (ii) fifteen (15) days after receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties and (iii) the date set forth in such notice (which shall not be more than one hundred eighty (180) days after the fifteenth (15th) anniversary of the ON Line COD). Great Basin shall make Applicable Transfer Representations and Warranties to the NVE Parties in connection with such Transfer. At any time after the sixth (6th) anniversary of GB Segment Financial Closing, upon Great Basin’s request, the NVE Parties shall state in writing whether in their view the circumstances described in Section 3.07(a)(iii) existed as of the GB Segment COD Deadline (such that, in the NVE Parties’ view, the NVE Parties’ right to elect to so purchase all

Privileged and Confidential

Execution Version

of Great Basin’s Ownership Interests had been triggered) and Great Basin shall be entitled to rely on such written statement (but shall not be bound by such statement in the event of a Dispute among the Parties), it being understood that such a written statement by the NVE Parties shall under no circumstances operate as a notice of the NVE Parties’ election to exercise any purchase right that may have been triggered (such election by the NVE Parties requiring a separate written notice, timely delivered as provided in this Section 3.07(a)).

(b) The GB Segment Financial Closing Deadline and the GB Segment COD Deadline shall be subject to extension for any event of Force Majeure to the extent that such event causes a delay in an activity required for Great Basin to achieve GB Segment Financial Closing or for GB Segment COD to occur which activity cannot, despite the exercise of commercially reasonable efforts, be delayed without extending the day on which GB Segment Financial Closing or GB Segment COD, as applicable, will occur.

3.08 30th Anniversary Buyout Right. The NVE Parties shall have the right to purchase all (but not less than all) of Great Basin’s Ownership Interests for a price determined in accordance with Schedule 5; provided that written notice of their election to exercise such right is provided to Great Basin by the twenty-ninth (29th) anniversary of the ON Line COD (but not earlier than the twenty-seventh (27th) anniversary of the ON Line COD).

If the NVE Parties timely elect to exercise such right, subject to obtaining PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties (which approvals the NVE Parties will timely seek prior to or upon their election to exercise such right), then Great Basin shall Transfer all of its Ownership Interests to the NVE Parties free and clear of any Liens other than Permitted Liens on the forty-first (41st) anniversary of the ON Line COD. If such PUCN Approval and Governmental Approvals are not received by the date that is six (6) months prior to the forty-first (41st) anniversary of the ON Line COD, then, unless the parties otherwise agree in writing, the NVE Parties shall be deemed to have withdrawn their election to exercise such right; provided, that on or prior to such date, the NVE Parties may elect (such election being irrevocable) to renew their Capacity Entitlements pursuant to Section 3.09(b); and, provided, further, that it is understood and agreed that (i) neither Great Basin nor any of its Affiliates will intervene in any regulatory proceeding of the NVE Parties relating to the PUCN Approval or any Governmental

Approvals (notwithstanding Section 4.05(a)) unless requested to do so by the NVE Parties and if the NVE Parties so request, Great Basin or its Affiliate, as applicable, will support the NVE Parties’ request to acquire Great Basin’s Ownership Interests pursuant to this Section 3.09(a) in such proceeding and (ii) in no event shall the Transfer of all of Great Basin’s Ownership Interests to the NVE Parties occur after the forty-first (41st) anniversary of the ON Line COD. In the event the NVE Parties do not make such renewal election, then the NVE Parties shall permanently revoke their election to acquire Great Basin’s Ownership Interests and forever waive all of their rights under this Section 3.09. Great Basin shall make Applicable Transfer Representations and Warranties to the NVE Parties in connection with such Transfer.

(b) The NVE Parties shall have the right to renew all (but not less than all) of each Party’s Capacity Entitlements for a period of one year or more commencing as of the forty-first (41st) anniversary of ON Line COD for a fixed rental payment calculated in accordance with Schedule 5; provided that (i) such renewal period when added to the forty-one (41) year initial term commencing on the ON Line COD does not extend for more than eighty percent (80%) of the then re-estimated useful life of Great Basin’s Ownership Interest subject to such renewal measured from the ON Line COD and (ii) Great Basin’s Ownership Interest subject to such renewal will have a value at the termination of such renewal equal to at least twenty percent (20%) of the initial value of such interests measured as of the ON Line COD (without giving effect to inflation or deflation), in each case determined at the time of such renewal. If Great Basin and the NVE Parties cannot agree as to the calculations of the estimated value or useful life of Great Basin’s Ownership Interest subject to such renewal, then the Parties shall mutually select the Independent Auditor or another external auditor or appraiser, as determined based on the nature of the dispute, which shall be instructed to resolve such disagreement within thirty (30) days after such disagreement is submitted to it for resolution and shall notify Great Basin and NPC in writing of its resolution. Such auditor’s or appraiser’s resolution of the disagreement shall be final and binding on the Parties.

(c) Notwithstanding anything herein to the contrary, in the event the NVE Parties do not (i) purchase all of Great Basin’s Ownership Interests or (ii) renew their Capacity Entitlements pursuant to Section 3.09(b), then from and after the forty-first (41st) anniversary of ON Line COD, the Parties shall have the Capacity Entitlements set forth in the first sentence of Section 3.02(e) and all Operating Costs, Event of Loss Costs, Condemnation Action Costs and Capital Repair Costs, in each case, in respect of ON Line shall be funded by the Parties in accordance with their respective Ownership Percentages and Great Basin shall have no right to recover Great Basin’s Ownership Percentage of any such costs from the NVE Parties.

Majeure event causes ON Line to become unavailable to one or both of the NVE Parties) during such Force Majeure but for no longer period and only to the extent performance of such obligations are prevented or delayed by such Force Majeure. The Claiming Party shall exercise due diligence to remedy the Force Majeure within a reasonable period. Force Majeure shall not entitle any Party to terminate this Agreement.

3.11 Transmission Systems. Nothing in this Agreement shall prevent a Party from making any additions, modifications or changes to its respective transmission system. Each Party shall provide reasonable notice to the other Parties, to the extent required by the PUCN, FERC, NERC, WECC, or their successors in interest, of such additions, modifications or changes to its transmission systems.

3.12 Additional Uses. Notwithstanding anything to the contrary in this Agreement, (a) the NVE Parties shall have all of the rights associated with any additional uses arising with respect to ON Line, and Great Basin shall have all of the rights associated with any additional uses of the Great Basin Segments, in each case, prior to the adjustment of Great Basin’s Capacity Entitlement pursuant to Section 3.02(b) or 3.02(e) (and any rights arising prior to such adjustment shall not be impacted thereby) and (b) the Parties shall share all of the rights associated with any additional uses arising with respect to the Transmission Line thereafter in proportion to their respective Capacity Entitlements; provided, however, that the NVE Parties shall be entitled to the exclusive rights associated with any additional uses of the Double Circuit Towers regardless of whether arising before or after the adjustment of Great Basin’s Capacity Entitlement pursuant to Section 3.02(b) or 3.02(e). Notwithstanding anything herein to the contrary (other than as provided hereunder in respect of the NVE Parties’ exclusive rights associated with any additional uses of the Double Circuit Towers), in the event the NVE Parties do not (i) purchase all of Great Basin’s Ownership Interests or (ii) renew their Capacity Entitlements pursuant to Section 3.09(b), from and after the forty-first (41st) anniversary of the ON Line COD, the Parties shall share all of the rights associated with any additional uses with respect to ON Line in proportion to their respective Ownership Percentages and Great Basin shall have all of the rights associated with any additional uses arising with respect to the Great Basin Segments; provided, however, that if, prior to the forty-first (41st) anniversary of the ON Line COD, the NVE Parties shall have committed all or any part of the rights associated with any additional uses to one or more third parties in one or more transactions having a term that extends beyond such anniversary, then (x) the rights of Great Basin with respect to such additional uses shall be subject to the rights of such third parties and (y) from and after such anniversary, any revenues payable to the NVE Parties under such transactions shall be shared between the NVE Parties and Great Basin in proportion to their respective Ownership Interests.

Each Project Budget may include amounts for the reimbursement of direct internal labor costs incurred by any Party or its Affiliates for employees directly engaged in the performance of ON Line Activities or Capital Repairs, as applicable (other than any costs of either Party with respect to its Authorized Representatives); provided, however, that such internal labor costs shall: (i) not include any amounts attributable to general administrative costs or overhead costs not associated with direct internal labor for employees directly engaged in the performance of ON Line Activities or Capital Repairs, as applicable, and (ii) only include internal labor costs directly attributable to ON Line that would not have been incurred if work was not being performed for ON Line Activities or Capital Repairs, as applicable. A Party seeking reimbursement for direct internal labor costs incurred in accordance with the applicable Project Budget and this Section 5.01(d) shall keep reasonably detailed records of such costs and shall provide such records to the other Parties upon request.

5.02 Compliance with Project Budget; Amendments. The Managing Party and NPC, as applicable, shall use commercially reasonable efforts to manage, or cause to be managed, the commitment of funds so that costs will not exceed funds committed or to be committed by the Parties pursuant to the applicable Project Budget.

prepare an amended Project Budget for approval by the Management Committee at the next regular meeting or at a special meeting called by a Party for such purpose as soon as reasonably practicable following such determination.

5.03 Funding ON Line Costs.

(a) Each Party shall be solely responsible for funding, and shall timely fund, all of its own Development Costs and all of its own Pre-Closing Costs, in each case subject to Section 2.02, and Great Basin shall be solely responsible for funding, and shall timely fund, all other liabilities and obligations in respect of ON Line arising through the Acquisition Closing Date. Commencing after the Acquisition Closing Date, each Party shall pay for its Ownership Percentage of all Post-Closing Costs arising thereafter in accordance with this Agreement to the extent that, when added to any Development Costs and Pre-Closing Costs funded by such Party (as adjusted by any Closing Payments), such Party has funded up to its respective Ownership Percentage of the ON Line Budget. No Party shall charge a fee to any other Party for performance of its responsibilities as the Managing Party under this Agreement. Subject to Section 16.02(e)(i) and (ii), respectively, (i) Great Basin, in its capacity as the Managing Party, shall be responsible for reviewing invoices for Pre-Closing Costs (other than costs incurred in respect of the NVE Project) and, from and after the Effective Date, reconciling the payments for such costs to the ON Line Budget on a monthly basis and (ii) NPC, in its capacity as the Managing Party, shall be responsible for reviewing invoices for Post-Closing Costs (including invoices for Direct Pay Amounts) and reconciling the payments for such costs to the ON Line Budget on a monthly basis. Great Basin shall be responsible for timely paying amounts payable in respect of Pre-Closing Costs (other than costs incurred in respect of the NVE Project). NPC shall be responsible for timely paying amounts payable by the Parties in respect of Post-Closing Costs (other than Direct Pay Amounts) from the amounts on deposit in the ON Line Account.

(b) NPC shall establish (on or before the Acquisition Closing Date) and maintain a depositary account (the “ON Line Account”) in its name at a financial institution to be selected with the consent of the Management Committee, into which each Party shall deposit its Ownership Percentage of the funds to pay for all Post-Closing Costs (other than Direct Pay Amounts) in accordance with this Agreement. In any period during which Great Basin is exercising its remedy set forth in Section 16.02(e)(i), NPC shall cause the payments to be made from the ON Line Account as directed by Great Basin.

(i) Subject to Section 5.03(d), NPC and Great Basin shall pay their respective Ownership Percentages (and, in the case of NPC, SPPC’s Ownership Percentage) of all Direct Pay Amounts when due in accordance with the ON Line Budget and the applicable Material Construction Contract and each Party shall fund into the ON Line Account on a monthly basis its Ownership Percentage of all Post-Closing Costs (other than Direct Pay Amounts) in accordance with Section 5.03(c)(ii).

(ii) On a monthly basis but in any event no later than the fifth (5th) Business Day of each month, the Managing Party shall submit to the other Parties (A) an invoice of funds that each Party is liable for under this Agreement for the

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

previous month and (B) a statement reconciling the prior invoice or invoices in the event the actual amount(s) for which each Party was liable during such month changed as a result of refunds, credits, change orders or other adjustments made to such invoices by the counterparty to the underlying contract. Each invoice and reconciliation statement shall be accompanied by reasonable supporting documentation showing the amounts properly due and payable, a breakdown of the Post-Closing Costs (other than Direct Pay Amounts) represented in such invoice or reconciliation statement, copies of the underlying invoices and supporting materials, and such other supporting documentation as may be reasonably requested by Great Basin in order to submit requisitions and obtain funds under the ON Line Financing Agreements. Any amounts due pursuant to an invoice or reconciliation statement shall be due and payable two (2) Business Days prior to the current month end, or on such later date as may be otherwise set forth in the invoice or reconciliation statement. If a reconciliation statement shows that prior payments by a Party exceeded the actual amount for which such Party was liable, such excess amount shall be credited against the amounts due by such Party in the invoice accompanying such reconciliation statement, or in the event that such excess amount exceeds such Party’s payment obligations under such invoice, the difference between the excess amount determined by such reconciliation statement and the payment obligations of such Party under such invoice shall be paid to such Party no later than two (2) Business Days prior to the current month end.

(d) The Managing Party shall provide the other Parties written notice of any expected Initial Cost Differential or Incremental Cost Differential as soon as reasonably practicable upon receiving notice of any such costs. If, within ten (10) days after receipt of such notice, Great Basin does not elect to fund any such Initial Cost Differential or Incremental Cost Differential, Great Basin shall have no right or obligation to fund its Ownership Percentage of any such Initial Cost Differential or Incremental Cost Differential. If Great Basin does timely elect (such election being irrevocable) to fund its Ownership Percentage (and, in the circumstances described in Section 5.03(e), the NVE Parties’ Ownership Percentage) of any such Initial Cost Differential or Incremental Cost Differential, then Great Basin shall timely fund any such Initial Cost Differential or Incremental Cost Differential, as applicable, and the amount of any such Initial Cost Differential or Incremental Cost Differential funded by Great Basin shall be reflected in the Monthly Payment as provided in Section 3.06. To the extent that Great Basin does not timely fund its Ownership Percentage of any Initial Cost Differential or Incremental Cost Differential, the NVE Parties may fund any such portion, and upon (i) the earliest to occur of (A) ON Line COD, (B) an Event of Default by Great Basin, (C) a Condemnation Action or Event of Loss related to ON Line, (D) an election of a right to purchase Ownership Interests under this Agreement and (E) any other material event regarding ON Line as reasonably determined by the NVE Parties and (ii) fifteen (15) days after such earliest date and receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties, each Party’s Ownership Percentage shall be adjusted such that, following the adjustment, such Party’s Ownership Percentage shall equal a ratio (A) the numerator of which is equal to the portion of the Total Costs paid by such Party and (B) the denominator of which equals the aggregate amount of the Total Costs, and Great Basin shall Transfer the portion of its Ownership Interest corresponding to its excess above its revised Ownership Percentage to the NVE Parties free and clear of any Liens other than Permitted Liens. Great Basin shall execute and record any

bills of sale, deeds, certificates, memorandum and other documentation as reasonably requested by the NVE Parties to evidence the re-allocation of such interests. Great Basin shall make Applicable Transfer Representations and Warranties in connection with such Transfer.

(e) Notwithstanding anything herein to the contrary, to the extent that the NVE Parties do not timely fund their aggregate Ownership Percentage of any Initial Cost Differential or Incremental Cost Differential, Great Basin shall have the right, but not the obligation, to (A) fund the entire amount of such Initial Cost Differential or Incremental Cost Differential and (B) take over primary responsibility for managing and directing the completion of construction of ON Line as provided in Section 16.02(e)(i).

5.04 Funding of Capital Repair Costs.

(a) NPC shall establish (on or before the ON Line COD) and maintain a depositary account (the “Capital Repair Account”) in its name at a financial institution to be selected with the consent of the Management Committee, in to which each Party shall deposit its Ownership Percentage of the funds to pay for all Capital Repair Costs in accordance with the Capital Repair Budget and this Agreement.

(b) After ON Line COD:

(i) Subject to Section 5.04(c), each Party shall fund into the Capital Repair Account on a monthly basis its Ownership Percentage of all Capital Repair Costs (other than Direct Pay Amounts) in accordance with Section 5.04(b)(ii).

(ii) On a monthly basis but in any event no later than the fifth (5th) Business Day of each month, NPC shall submit to the other Parties (A) an invoice of funds that each Party is liable for under this Agreement for the previous month and (B) a statement reconciling the prior invoice or invoices in the event the actual amount(s) for which each Party was liable during such month changed as a result of refunds, credits, change orders or other adjustments made to such invoices by the counterparty to the underlying contract. Each invoice may also include any actual costs for which a Party is liable under this Agreement arising prior to the time such invoice is issued in respect of prior month(s). Each invoice and reconciliation statement shall be accompanied by reasonable supporting documentation showing the amounts properly due and payable, a breakdown of the Capital Repair Costs represented in such invoice or reconciliation statement, copies of the underlying invoices and supporting materials, and such other supporting documentation as may be reasonably requested by Great Basin in order to submit requisitions and obtain funds under the ON Line Financing Agreements. Any amounts due pursuant to an invoice or reconciliation statement shall be due and payable two (2) Business Days prior to the current month end, or on such later date as may be otherwise set forth in the invoice or reconciliation statement. If a reconciliation statement shows that prior payments by a Party exceeded the actual amount for which such Party was liable, such excess amount shall be credited against the amounts due by such Party in the invoice accompanying such reconciliation statement, or in the event that such excess amount exceeds such Party’s payment obligations under such invoice, the difference between the excess amount determined by such reconciliation statement

If Great Basin does timely elect (such election being irrevocable) to fund its Ownership Percentage of any such Capital Repair Costs, then Great Basin shall timely fund its Ownership Percentage of any such Capital Repair Costs, and the amount funded by Great Basin in respect of Capital Repair Costs be reflected in the Monthly Payment as provided in Section 3.06. To the extent that Great Basin does not timely fund its Ownership Percentage of any Capital Repair Costs, but subject to Section 5.04(d), the NVE Parties shall fund any such portion, and upon (i) the earliest to occur of (A) any anniversary of the ON Line COD, (B) an Event of Default by Great Basin, (C) a Condemnation Action or Event of Loss related to ON Line, (D) an election of a right to purchase Ownership Interests under this Agreement, and (E) any other material event regarding ON Line as reasonably determined by the NVE Parties and (ii) fifteen (15) days after such earliest date and receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties, each Party’s Ownership Percentage shall be adjusted such that, following the adjustment, such Party’s Ownership Percentage shall equal a ratio (x) the numerator of which is equal to the portion of the Total Costs paid by such Party and (y) the denominator equals the Total Costs, and Great Basin shall Transfer the portion of its Ownership Interest corresponding to its excess above its revised Ownership Percentage to the NVE Parties free and clear of any Liens other than Permitted Liens. Great Basin shall execute and record any bills of sale, deeds, certificates, memorandum and other documentation as reasonably requested by the NVE Parties to evidence the re-allocation of such interests. Great Basin shall make Applicable Transfer Representations and Warranties in connection with such Transfer.

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

costs giving rise to such Cost Reduction (it being understood for the avoidance of doubt that such Cost Reductions shall be paid solely to, and for the account of, the NVE Parties to the extent they were received in respect of Capital Repairs, an Event of Loss in respect of ON Line or Condemnation Action in respect of ON Line, in each case, not funded by Great Basin).

5.06 Invoicing and Payment.

(a) All payments made by a Party under Sections 5.03(c)(ii) and 5.04(b)(ii) shall be made in Dollars by electronic funds transfer or wire transfer in immediately available funds for receipt by the due date to the applicable Project Account or to such other Person(s) as the Management Committee may determine.

(b) Each Party shall make all Contributions required hereunder as and when due, without demand, counterclaim, setoff, deduction or defense, and each Party waives, to the extent permitted by Applicable Law, all rights now or hereafter conferred by statute or otherwise with respect to any such demand, counterclaim, setoff, deduction or defense to the applicable account or accounts.

5.07 Defaulted Contributions.

(a) If a Party fails to pay the full amount of any payments when required to do so pursuant to Sections 5.03(c) or 5.04(b) (each, a “Contribution” and such Party, the “Non-Contributing Party”), then any Party that has paid its Contribution (the “Contributing Party”) shall have the right, but not the obligation, to make an advance (an “Advance”) on behalf of the Non-Contributing Party in respect of the unpaid Contribution of the Non-Contributing Party (the “Unpaid Contribution”). Such Advance shall bear interest at a rate equal to the Default Rate from the date such Advance was made until the date such Advance is fully repaid in cash by the Non-Contributing Party. Advances shall be repaid, with interest at the Default Rate, by the Non-Contributing Party at any time after the date the Advance is made upon written demand therefor by the Contributing Party. Each Advance shall be an obligation of the Non-Contributing Party to the Contributing Party and the Contributing Party may enforce and recover from the Non-Contributing Party the Advance in accordance with any of its remedies hereunder or at equity or in law. If either of the NVE Parties is the Non-Contributing Party, then the other NVE Party, as applicable, shall have the first right to be the Contributing Party, which right must be exercised within five (5) Business Days after the date the Unpaid Contribution was required to be made. Each Advance for an Unpaid Obligation shall cure any Event of Default therefor with respect to the Party that is not the Contributing Party or the Non-Contributing Party.

(b) The election by a Party to make or not to make an Advance in respect of an Unpaid Contribution shall not operate as waiver of the rights of such Party under this Agreement or at law or in equity, including the right to claim damages as a result of such Unpaid Contribution, and Advances made in respect of an Unpaid Contribution shall not relieve the Non-Contributing Party of its obligations hereunder.

5.08 Payment on Non-Business Day. If any Contribution under this Agreement is required to be made on a day other than a Business Day, the due date for such

5.09 Project Accounts. All Project Accounts established pursuant to this Agreement shall be in the name of NPC and used solely for the purposes set forth in this Agreement. Funds on deposit in each Project Account shall be kept in or swept into interest-bearing accounts to the extent reasonably practicable but in no event shall any such funds be commingled with any other funds of NPC or its Affiliates. All interest accrued on the amounts in each Project Account shall accrue to the benefit of the NVE Parties; provided, that to the extent any amounts funded by Great Basin are kept in any Project Account for more than thirty (30) days, Great Basin shall be entitled to interest accrued on such amounts from the date such amounts are deposited into the Project Account until they are disbursed.

6.01 Transmission Improvements. If any improvements on the transmission systems of the NVE Parties are undertaken for any reason prior to GB Segment Financial Closing (including as specified in Schedule 1) that would otherwise be made as part of the construction of the Great Basin Segments (each, a “Transmission Improvement”), then NPC or SPPC, as applicable, shall initially bear the full cost of any such Transmission Improvement and Great Basin shall pay to NPC or SPPC, as applicable, at GB Segment Financial Closing an amount for any such Transmission Improvement equal to the lesser of (a) the actual cost (adjusted for depreciation) incurred by NPC or SPPC, as applicable, for any such Transmission Improvement and (b) any avoided cost to the Great Basin Segments by reason of any such Transmission Improvement. If Great Basin pays to NPC or SPPC, as applicable, at GB Segment Financial Closing for any such Transmission Improvement, then, NPC or SPPC, as applicable, shall transfer title to such Transmission Improvement (to the extent owned by the NVE Parties) to Great Basin at GB Segment Financial Closing pursuant to documentation reasonably satisfactory to Great Basin, and NPC or SPPC, as applicable, shall make the Applicable Transfer Representations and Warranties to Great Basin in connection with such transfer.

(c) At least six (6) months prior to the anticipated GB Segment Financial Closing, the NVE Parties shall submit to Great Basin an indicative estimate of the annual costs and expenses to be incurred by the NVE Parties to operate the Great Basin Segments. At least six (6) months prior to the anticipated date of commercial operation of each Great Basin Segment, and thereafter at least ninety (90) days prior to each anniversary of the commercial operation date of each Great Basin Segment, the NVE Parties shall prepare and submit an annual Operating Plan for the Management Committee’s review and discussion, but not approval.

In order to enable the NVE Parties to monitor and operate the Great Basin Segments, Great Basin shall provide, at the request of the NVE Parties, its annual maintenance and proposed outage schedules for its facilities; provided, that Great Basin’s provision of such schedules shall not constitute acceptance or approval by the NVE Parties of such schedules.

7.03 Operational and Maintenance Standards.

(a) The NVE Parties shall cause the Transmission Line to be operated, and ON Line to be maintained, in accordance with (i) Prudent Utility Practices (including any Electric Reliability Organization requirements), (ii) Governmental Approvals for the Transmission Line (or applicable portion thereof) and (iii) Applicable Law.

(b) The NVE Parties may, in accordance with the following provisions, direct the other Parties to interrupt or reduce deliveries of electrical power on the Transmission Line (i) when necessary in order to maintain, repair, replace, remove, investigate, inspect or test any part of the Transmission Line or any meters for the Transmission Line, (ii) if

Privileged and Confidential

Execution Version

the NVE Parties determine, in their sole discretion, that interruption or reduction is necessary for safety or emergencies or reasonably conclude that the energy delivered to or transmitting on the Transmission Line does not conform to Prudent Utility Practices or this Agreement or jeopardizes the integrity or use of the transmissions system or Transmission Line or (iii) if it is otherwise required to do so in accordance with Electric Reliability Organization requirements. With respect to any interruption or reduction of deliveries of electrical power pursuant to clauses (i)-(iii) of the preceding sentence, the NVE Parties shall limit the length of any such interruption or reduction to that time reasonably necessary to correct the problem or comply with the Electric Reliability Organization requirements, as applicable. In any of these events, the curtailment shall be accomplished in proportion to each Party’s Capacity Entitlement and/or use, as applicable, on the Transmission Line, except where curtailing in such a manner is not consistent with Prudent Utility Practices. Each Party shall promptly effect such interruption in, or reduction of, delivery as the NVE Parties shall direct pursuant to this Section 7.03(b) upon notice from the NVE Parties. In the event notice is impracticable or a Party fails to promptly comply therewith, the NVE Parties may effect the same by direct action. If any NVE Party becomes aware that a Party is using the Transmission Line in excess of its Capacity Entitlement or its rights to Fiber Optic Capacity or Microwave Capacity as set forth in Section 3.03, then the NVE Parties shall have the authority to cause the excess usage to be curtailed.

(c) Notwithstanding anything to the contrary in this Agreement, any Party may subcontract any or all of its maintenance obligations under this Article VII to an Independent Contractor pursuant to a Maintenance Agreement; provided, however, that (i) no such agreement shall relieve such Party from its obligations under any related provisions of this Agreement and (ii) such Independent Contractor is reasonably acceptable to the other Parties.

7.04 Balancing Authority; Balancing Authority Area. Subject to Section 16.02(e)(iii), the Transmission Line shall be within one or both of the NVE Parties’ Balancing Authority Area and one or both of the NVE Parties shall be the Balancing Authority for the Transmission Line.

Great Basin shall reimburse the NVE Parties for any services provided pursuant to the Balancing Authority Area Services Agreement in accordance with the requirements of such agreement.

7.05 Ancillary Services. Neither of the NVE Parties shall be required to provide any Ancillary Services to Great Basin, except to the extent set forth in a separate agreement (including any Balancing Authority Area Services Agreement) for the provision of such Ancillary Services (if any) between NPC and Great Basin or SPPC and Great Basin, as applicable.

7.06 Transmission Losses. On and after the date of commercial operation of the first Great Basin Segment to achieve commercial operation, losses on the Transmission Line (“Transmission Losses”) shall be allocated as follows: (a) Transmission Losses on ON Line associated with the NVE Parties’ Capacity Entitlement on ON Line shall be calculated first, as if the Great Basin Segments had not been built (i.e., line loading will be at a minimum 600MW) and such losses will be borne solely by the NVE Parties; and (b) all subsequent or additional Transmission Losses associated with the remaining Electrical Capacity over ON Line and over

Accordingly, (i) each Authorized Representative shall have power to act (or refrain from acting) solely in accordance with the wishes of the Party or Parties that designated such Authorized Representative, (ii) the acts of an Authorized Representative in respect of any matter shall be deemed to be the acts of the Party or Parties that designated such Authorized Representative and (iii) no Authorized Representative shall owe (or be deemed to owe) any duty (fiduciary or otherwise) to any Party other than the Party or Parties that designated such Authorized Representative. Each of Great Basin and the NVE Parties shall be responsible for the compensation and expenses of its or their Authorized Representatives. Notwithstanding the foregoing, no Authorized Representative, in such capacity, shall have the authority to amend, waive, revise, modify or terminate this Agreement or any portion thereof, serve any notice alleging breach of this Agreement, enter into, settle or otherwise dismiss any arbitration proceeding under Section 19.02 or claim or accept a claim of Force Majeure as an excuse to performance under this Agreement.

Committee, and no Party shall withhold the presence or participation of its Representative or Alternate Representative to prevent, delay or forestall decisions on matters under consideration by the Management Committee. The Parties shall cause their respective Authorized Representatives not to unreasonably withhold, condition or delay any actions of the Management Committee. A reasonable number of other employees or agents of the Parties may attend meetings of the Management Committee. Meetings may be conducted in person, by telephone or video conference call, or by other means which permit an Authorized Representative of each Party to be verified and to hear and be heard by the other Authorized Representative and which are acceptable to both Authorized Representatives. Attendees who are not Representatives, or in the case that a Representative is not in attendance, who are not the applicable Alternate Representative, shall be identified at the commencement of such meeting and shall have no power to vote on any matters, but may participate in discussions in accordance with the Management Committee’s rules of order, which may limit the amount of time that the employees or other agents may participate.

(c) Meeting; Notice. Unless the Parties agree otherwise, the Management Committee shall meet as necessary or appropriate (i) but no less frequently than monthly from the Effective Date until the commencement of the Operating Period and quarterly thereafter and (ii) at special meetings called by any Party following five (5) Business Days’ prior written notice of such a special meeting to the other Party’s Representative and so long as such meeting is reasonable under the circumstances. The Chair of the Management Committee shall provide written notice to the other Authorized Representatives stating the place (or means if by telephone conference or other means), date and hour of each meeting of the Management Committee, together with a detailed agenda for the meeting, not less than five (5) days before the date of the meeting (unless such notice is waived by an Authorized Representative of each Party either at the meeting or by written consent before or after the meeting). Any Party may submit an item for inclusion on the agenda of any Management Committee meeting. Attendance of an Authorized Representative of a Party at a meeting of the Management Committee shall constitute a waiver of notification of the meeting by such Party.

(d) Rules. The Management Committee may adopt such rules of order, policy statements and directives as it considers necessary or appropriate for the conduct of its business and the exercise of its powers, none of which shall conflict with this Agreement or any ON Line Agreement.

(e) Chair. The Representative of the NVE Parties shall serve as the initial chairperson of the Management Committee (the “Chair”). Unless the Management Committee decides otherwise, commencing on the first day of each calendar year following the Effective Date, the Chair of the Management Committee shall rotate between (i) the Representative for the NVE Parties and (ii) the Representative for Great Basin. The Chair shall be responsible for the maintenance of minutes of each Management Committee meeting and the recordation of the results of each vote taken and shall promptly provide a copy of such minutes and voting records to the other Authorized Representatives. The Chair shall have no powers or duties other than those specifically conferred by this Agreement, and shall have no voting or veto power in addition to the right to vote as a Representative. In the absence of the Chair at any

Management Committee meeting, the applicable Alternative Representative shall be the Chair for such meeting.

(f) Quorum and Voting. Except as provided in Section 16.02(c), meetings of the Management Committee shall require a quorum consisting of (i) an Authorized Representative of the NVE Parties and (ii) an Authorized Representative of Great Basin. If a quorum is not present at the commencement of any meeting, the Chair will reschedule the meeting to take place within the following ten (10) days and will give notice of such rescheduled meeting to the Representatives and Alternate Representatives. If at two successive meetings following the originally scheduled meeting a quorum is not present due to the same Party’s Authorized Representative not being present at such meetings, then, if such Party’s Authorized Representative is not present for the last such meeting, the attendance of the other Party’s Authorized Representative at such meeting shall constitute a quorum. Subject to Sections 8.01(f) and 16.02(c), all decisions of the Management Committee shall require the affirmative vote of (i) an Authorized Representative of the NVE Parties and (ii) an Authorized Representative of Great Basin.

(g) Action by Written Consent. Any action which may be taken by the Management Committee under this Agreement may be taken without a meeting if each Representative and Alternate Representative is given prior notice in writing or by telephone or facsimile transmission and a copy of the proposed consent, and a consent setting forth the action taken is executed by (i) an Authorized Representative of the NVE Parties and (ii) an Authorized Representative of Great Basin.

(h) Deadlocks. If the Authorized Representatives participating in a meeting of the Management Committee are unable to reach agreement on a matter put to vote (a “Deadlock”), the Parties shall attempt to resolve such Deadlock through negotiations of the Authorized Representatives. If such Deadlock is not resolved within seven (7) days, the Deadlock shall be referred to a panel consisting of a senior executive (President or Vice President) of each Party with the authority to resolve the matter causing such Deadlock. Such panel shall convene within seven (7) days after the expiration of the aforementioned seven (7)- day period and the members of such panel shall attempt in good faith to promptly resolve such Deadlock. Notwithstanding a Deadlock regarding the use of contingency in the ON Line Budget, the Managing Party may utilize contingency in the ON Line Budget to fund any Critical Change Order.

(i) If a Deadlock occurs prior to ON Line Financial Closing and the Parties are unable to achieve a resolution of such Deadlock within seventy-five (75) days after the panel of senior executives has convened or ninety (90) days after the Deadlock occurred, whichever occurs sooner, then any Party may elect to terminate this Agreement pursuant to Section 11.03(a)(v).

(ii) If a Deadlock arises regarding the approval of any amount in a Capital Repair Budget or any Capital Repair, the remainder of the Capital Repair Budget approved shall take effect. Notwithstanding such Deadlock, the NPC may carry out Critical Capital Repairs.

10.01 Management of Tax Matters. Except for any payments of Personal Taxes or payments in lieu thereof which are directly billed to a Party by any taxing authority and which a Party shall pay directly, and subject to the oversight of the Management Committee, the Managing Party prior to the Operating Period and NPC during the Operating Period shall have the authority and responsibility for administering, coordinating, filing returns, making property tax declarations, paying, seeking official tax rulings or determinations, and other related functions pertaining to all taxes, payments in lieu of taxes, assessments, impositions, charges, and related costs of every kind and nature, ordinary, or extraordinary, general or special, foreseen or unforeseen, settled or pending settlement connected with or arising out of the development, construction, ownership, operation, maintenance, alteration, repair, rebuilding, use or retirement of ON Line or any part thereof, including sales taxes and excise taxes (collectively “Taxes”)

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

which are or may be imposed by any Governmental Authority; provided, however, that unless specifically authorized in writing by the Parties, such authority shall not extend to any act or action affecting any exemption from Taxes or special tax treatment arising out of ON Line to which one Party may be entitled on a basis that is different from the other Parties. As used herein, the term “Taxes” shall not include any taxes associated with the Great Basin Segments or net income taxes or franchise taxes relating to ON Line that are assessed or imposed against any Party (collectively, “Personal Taxes”), the payment of which is and shall remain the responsibility of any such Party so assessed or on whom imposed. Each Party may contest the validity or amount of any Personal Taxes, in each case provided that the contested Personal Taxes shall not remain unpaid for such length of time as shall permit any part or all of ON Line to be sold or foreclosed or any interest of any Party therein to be subject to a Lien for the nonpayment of the same.

10.02 Sharing of Taxes and Related Payments. All Taxes whether Pre-Closing Costs, Post-Closing Costs or Operating Costs, as applicable, after the Acquisition Closing Date, shall be shared and borne by the Parties in proportion to their respective Ownership Percentages; provided, however, that to the extent that the aggregate amount of the Taxes are reduced because a Party is entitled to specific tax benefits resulting from its status apart from ON Line, such Party shall be entitled to the entire benefit, to the extent of actual realization, of any exemptions from and reductions of Taxes connected with or arising out of the ownership, operation, maintenance, alteration, repair, rebuilding, use or retirement of ON Line or any part thereof. Unless agreed upon by the Parties, in no event shall a Party entitled to any exemption or reduction in Taxes be liable, directly or indirectly, for any payment in lieu of taxes that any other Party has agreed to make. Further, it is the express intention of the Parties that, for Federal income tax purposes, (a) Great Basin be treated as the owner of an undivided ownership interest in ON Line equal to its Ownership Percentage, (b) NPC be treated as the owner of an undivided ownership interest in ON Line equal to its Ownership Percentage and (c) SPPC be treated as the owner of an undivided ownership interest in ON Line equal to its Ownership Percentage, with each Party entitled to the respective tax benefits attributable thereto.

10.03 Payment of Taxes. Subject to Section 10.02, the Managing Party prior to the Operating Period and NPC during the Operating Period shall be responsible for paying and discharging all Taxes imposed by any Governmental Authority before the same become delinquent, except (a) those that are directly billed to a Party by any taxing authority and which such Party is responsible to pay directly and (b) those subject to a good faith contest and for which appropriate reserves have been established in accordance with GAAP.

10.04 Non-Creation of Taxable Entity. Notwithstanding any other provision of this Agreement, the Parties do not intend to create hereby at law any joint venture, partnership, association taxable as a corporation, trust, limited liability company or other entity for the conduct of any business for profit. The Parties agree to timely elect under Section 761(a) of the Code to exclude the transactions created by this Agreement from the application of Subchapter K, Chapter 1 of the Code, and the Parties agree to revise the terms of this Agreement to the extent and in a manner necessary to permit such election. If it is ultimately determined by an appropriate taxing authority that this Agreement is not eligible for an election out of Subchapter K, Chapter 1 of the Code, then the Management Committee shall make all Federal

and state income Tax elections. Each Party agrees to report on such Party’s separate return in a manner consistent with such exclusion election any items of revenue and expenditure attributable to such Party’s share of any revenue received and any expenditures made under this Agreement. Nothing in this Agreement will be construed as an undertaking by any Party to jointly sell any electrical transmission or other services or property. Each Party agrees to execute and deliver such additional documentation, including the statement required by Treasury Regulation 1.761-2(b)(2), as may be required from time to time to effect such exclusion to the extent permitted by law.

10.05 Transfer Taxes. Each Party shall be responsible for the timely payment of, and shall indemnify and hold harmless each other Party from and against, its respective Ownership Percentage (as existing immediately prior to such Transfer) of all transfer taxes (excluding taxes measured in whole or in part by net income), including sales, use, excise, stock, stamp, documentary, filing, recording, permit, license, authorization and similar taxes, fees, duties, levies, customs, tariffs, imposts, assessments, obligations and charges (collectively, “Transfer Taxes”) (if any) arising out of or in connection with the transactions contemplated by this Agreement related to ON Line; provided, however, that in connection with a Transfer (a) pursuant to Section 16.02(d) or (f), then the defaulting Party shall be responsible for one hundred percent (100%) of any Transfer Taxes resulting therefrom, (b) pursuant to Section 15.02(a), then each Party shall be responsible for Transfer Taxes in accordance with the terms of the ROFR Offer Notice, (c) to a third Person, such Transfer Taxes shall be borne one hundred percent (100%) by the Transferring Party, (d) pursuant to Sections 15.03(e) or (f), such Transfer Taxes shall be borne one hundred percent (100%) by Great Basin, (e) pursuant to Section 15.03(g) between Great Basin and its Affiliates or among the Affiliates of Great Basin, such Transfer Taxes shall be borne one hundred percent (100%) by Great Basin, (f) pursuant to Sections 15.03(a) or (d), such Transfer Taxes shall be borne one hundred percent (100%) by the NVE Parties and (g) pursuant to Section 15.03(g) (but only with respect to a Transfer to the NVE Parties), such Transfer Taxes shall be shared equally by Great Basin, on the one hand, and the NVE Parties, on the other hand. Each Party shall prepare and file all necessary documentation and tax returns with respect to such Transfer Taxes, and each Party shall cooperate with each other Party and take any action reasonably requested by each other Party, which does not cause the non-requesting Party to incur any cost or inconvenience, in order to minimize such Transfer Taxes. For the avoidance of doubt, any Taxes (including Transfer Taxes) payable in connection with the procurement of assets from third parties in connection with the construction, maintenance, repair and/or replacement of ON Line (or any portion thereof) shall be treated as Development Costs, Pre-Closing Costs, Post-Closing Costs and/or Capital Repair Costs, as applicable, and shall not be subject to this Section 10.05.

10.06 Duties Regarding Assessments. With respect to property Taxes, the Parties will use their reasonable best efforts to have any taxing or other Governmental Authority levying any such Taxes or payments in lieu thereof, or making any valuations of ON Line (or any portion thereof) for the purpose of levying any such Taxes or payments in lieu thereof or any beneficial interest or rights therein, assess and levy such Taxes or payments in lieu thereof directly against the Ownership Interest of each Party. All such Taxes or payments in lieu thereof levied against each Party’s Ownership Interest, excepting those Taxes or payments in lieu thereof levied against an individual Party on behalf of any other Party, will be the sole responsibility of

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

the Party upon whose Ownership Interest such Taxes or payments in lieu thereof are levied. If any property Taxes or payments in lieu thereof, are levied or assessed in a manner other than as specified in this Section 10.06, or if an individual Party is levied or assessed on behalf of ON Line or any other Party, the Management Committee will establish equitable practices and procedures for the apportionment among the Parties of such Taxes or payments in lieu thereof.

10.07 Periodic Payments. The Parties shall account for Monthly Payments for Federal income tax purposes in accordance with the allocation of such payments in Section 3.06.

(iv) Performing any activities necessary to comply with Applicable Law and Prudent Utility Practices and that are otherwise prudent to retire ON Line and protect the Parties from liability;

(v) Remedying and restoring the ON Line ROW; and

(vi) Directly or through agents, brokers or other Persons selected by the Management Committee (A) timely disposing of any remaining assets of ON Line by sale, auction, partition or otherwise, (B) depositing any proceeds of the disposition of assets of ON Line in a new bank account, and (C) undertaking other necessary steps for the winding-up of ON Line, including disbursing of any balance remaining in (1) the account referenced in clause (B) above, to the Parties in proportion to their respective Ownership Percentages and (2) any Project Account, to Great Basin to the extent any amount paid into such Project Account by Great Basin has not been disbursed, and otherwise, to the NVE Parties.

(c) Commencing thirty-five (35) years after the Effective Date, each Party shall establish and maintain a depositary account on terms reasonably acceptable to the other Parties (each, a “Wind-Up Reserve Account”); provided, that if, on the thirty-fifth (35th) anniversary of the Effective Date, the remaining useful life of ON Line is reasonably estimated to be in excess of seventeen (17) years, the Parties shall delay the establishment of the Wind-Up Reserve Account until a date that is reasonably estimated to be seventeen (17) years prior to the expiration of the useful life of ON Line. Simultaneously with the establishment of each Wind-Up Reserve Account, and each subsequent year thereafter, the Party establishing such account shall deposit an amount in its Wind-Up Reserve Account equal to (i) (A) such Party’s Ownership Percentage of the current estimated costs to implement the Wind-Up Events, as determined by the Management Committee (on an annual basis) less (B) the amount on deposit in the Wind-Up Reserve Account; divided by (ii) the estimated number of years, as determined by the Management Committee (on an annual basis), until commencement of the Wind-Up Events. Each Party may draw on the amounts deposited in its Wind-Up Reserve Account to fund its Ownership Percentage of the costs to implement the Wind-Up Events. Each Party may draw on the amounts deposited in the Wind-Up Reserve Accounts set up by any other Party to fund any such other Party’s share of costs incurred in respect of the Wind-Up Events to the extent such costs are not paid by any such other Party. After completion of the Wind-Up Events, any amounts remaining in a Wind-Up Reserve Account shall be paid to the Party establishing such account. If a Party does not have an Investment Grade Credit Rating on or at anytime after the later of (x) the thirty-fifth (35th) anniversary of the Effective Date, and (y) the date that is seventeen (17) years prior to the expiration of the useful life of ON Line, such Party shall grant a security interest to the other Parties in all of the right, title and interest in, to and under such Party’s Wind-Up Reserve Account, in form and substance acceptable to the other Parties, which security interest shall be maintained in full force and effect at all times thereafter until such Party obtains an Investment Grade Credit Rating; provided, however, that (1) any such security requirements impacting Great Basin shall be subject to the rights of the GB Segment Lenders and (2) in the case of Great Basin’s Wind-Up Reserve Account, such security interest may only be subordinated to (i) any ON Line Lender and (ii) Excluded Liens arising by operation of law after such security interest is granted and required by Applicable Law to be senior to such

(ii) Great Basin purchases all of the NVE Parties’ Ownership Interests, then, unless agreed otherwise by the Parties, upon consummation of such purchase (A) the following provisions shall cease to be of further force or effect: (1) Sections 3.01(c), 3.07, 3.08, 3.09, 11.02, 16.02(c), 16.02(e)(i) and 16.02(f) and (2) except as provided in clause (B) below, Articles II, IV, V, VIII, IX (other than Section 9.05), XIII and XIV, (B) Sections 6.04, 7.02, 13.06 and 14.06 shall be hereby amended such that Great Basin has the same obligations with respect to ON Line as it has with respect to the Great Basin Segments in such sections (it being understood that any notice under such Sections will be given to the Parties and not the Management Committee) and (C) Great Basin shall be responsible for all Operating Costs and Capital Repair Costs arising after the consummation of such purchase.

(d) Nothing in this Section 11.03 shall (i) relieve or release any Party of any liability or damages arising out of such Party’s breach of any provision of this Agreement prior to the effectiveness of the termination or (ii) impair the right of any Party to compel specific performance by another Party or the other Parties, as the case may be, of such Party’s obligations under this Agreement to the extent that such obligations have not become void and of no further force or effect as a result of the termination.

ARTICLE XII

INDEMNIFICATION; LIMITATION OF LIABILITY

12.01 Indemnification.

(a) Agreements to Indemnify. Subject to Sections 12.03 and 12.04, each Party, to the maximum extent permitted by Applicable Law, shall defend, protect, indemnify and hold each other Party, its Affiliates and their respective officers, directors, employees and agents (“Indemnified Persons”) harmless from and against any and all Claims resulting from, arising out of or in connection with (i) the gross negligence, intentional misconduct or fraudulent acts of such Party, its Affiliates or its or their respective officers, directors, employees or agents, arising in connection with this Agreement or the Transmission Line, (ii) such Party’s breach of any provision of this Agreement, (iii) the Personal Taxes of such Party and (iv) subject to Section 18.01(a), Liens in respect of an obligation of such Party that are placed on the Ownership Interests or other property of an Indemnified Person. Each Party shall use reasonable efforts to include in its Open Access Transmission Tariff an indemnity from such Party’s customers for the benefit of the Parties that is consistent with the indemnity provided by such Party’s customer to such Party; provided, however, that to the extent that such an indemnity has not been included or is ineffective (and except for Claims resulting from Willful

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

Misconduct/Gross Negligence of a Party), NPC and Great Basin shall, to the maximum extent permitted by Applicable Law, defend, protect, indemnify and hold, in the case of NPC, Great Basin and, in the case of Great Basin, the NVE Parties and, in each case their respective Indemnified Persons harmless from and against any Claims by such non-indemnifying Party’s electric, transmission and other customers resulting from, arising out of or in connection with the delivery of, interruption to or curtailment of electric, transmission or other service caused by the failure of the indemnifying Party to properly, in the case of NPC, operate the Transmission Line and maintain ON Line and, in the case of Great Basin, maintain the Great Basin Segments; provided, further, however, that in no event shall the liability of Great Basin, or the liability of the NVE Parties collectively, pursuant to this sentence exceed ten million Dollars ($10,000,000) in the aggregate for any Claims arising in any three-year period.

(b) Conduct of Claims. Each Indemnified Person shall, promptly after the receipt of notice of any Claim against such Indemnified Person in respect of which indemnification may be sought pursuant to this Section 12.01, notify any other Party from whom it seeks indemnity (“Indemnifying Party”) of any such Claim. No Indemnifying Party shall be obligated to indemnify such Indemnified Person with respect to any such Claim if such Indemnified Person fails to notify the Indemnifying Party thereof in accordance with the provisions of this Section 12.01(b) in sufficient time to permit the Indemnifying Party to defend against any such Claim and to make a timely response thereto, including any responsive motion or answer to a complaint, petition, notice or other legal, equitable or administrative process relating to any such Claim, but only insofar as such failure to notify the Indemnifying Party has actually resulted in material prejudice or damage to the Indemnifying Party. In case any Claim shall be made or brought against an Indemnified Person, the Indemnifying Party may, or if so requested by such Indemnified Person shall, assume the defense thereof with competent counsel of its selection to defend such Indemnified Person. In such circumstances, such Indemnified Person shall (i) at no cost or expense to such Indemnified Person, cooperate with the Indemnifying Party and provide the Indemnifying Party with such information and assistance as the Indemnifying Party shall reasonably request in connection with any such Claim and (ii) at its own cost and expense (unless a conflict would exist if the same counsel represented both the Indemnifying Party and the Indemnified Party or the Indemnified Party is or may be reasonably expected to be exposed to criminal liability, in which case the Indemnifying Party shall pay the cost and expense of separate counsel for the Indemnified Party), have the right to participate and be represented by counsel of its own choice with respect to any such Claim.

(c) Defense of Claims. If the Indemnifying Party assumes the defense of the relevant Claim, (i) the Indemnifying Party shall not be liable for any settlement thereof that is made without its written consent and (ii) the Indemnifying Party shall control the settlement of such Claim; provided, however, that the Indemnifying Party shall not conclude any settlement that requires any action or forbearance from action or payment or admission by the Indemnified Person or any of its Affiliates without the prior written approval of the Indemnified Person. The obligations of an Indemnifying Party shall not extend to any loss, damage or expense of whatever kind and nature (including all related costs and expenses) to the extent the same results from, after the receipt of notice of a Claim against an Indemnified Person, the taking by the Indemnified Person of any action (unless required by Applicable Law or applicable legal process) which prejudices the successful defense of such Claim, without, in any such case, the

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

prior written consent of the Indemnifying Party (such consent not to be required in a case where the Indemnifying Party has not assumed the defense of such Claim). The Indemnified Person shall afford the Indemnifying Party and its counsel the opportunity to be present at, and to participate in, conferences with all Persons, including Governmental Authorities, asserting any Claim against the Indemnified Person covered by the indemnities contained in this Section 12.01 or conferences with representatives of, or counsel for, such Indemnified Person held in connection with such indemnities.

(d) Any Claim indemnified against pursuant to this Section 12.01 shall be net of, but not limited to, any tax benefit actually recognized by an Indemnified Person and any Insurance Proceeds.

12.02 Contribution of Parties. Except as otherwise expressly set forth herein, if, after the Acquisition Closing Date, a Party bears more than its Ownership Percentage of any liability or obligation arising in connection with ON Line (other than any liability or obligation arising (a) under an Excluded Agreement, (b) from a Party’s business activities that are independent of ON Line and not attributable to ON Line or (c) that is to be borne in a manner other than in accordance with Ownership Percentages by the express terms of this Agreement) and such Party would not be required to indemnify any other Party under this Agreement for any Claim related to such liability or obligation (a “Shared Liability”), the other Parties (proportionally based on their respective Ownership Percentages) shall reimburse the Party that incurred the Shared Liability within ten (10) Business Days after written demand therefor, to the extent of such excess so that the Parties bear that liability or obligation in proportion to their respective Ownership Percentages. No Party shall have the right to settle or compromise any Claim with respect to a Shared Liability without the written approval of each other Party. For the avoidance of doubt, this Section 12.02 shall not require the NVE Parties to make payments for costs or expenses attributable to the Great Basin Segments.

12.03 Waiver of Damages.

(a) EXCEPT FOR DAMAGES PAID TO THIRD PERSONS TO WHICH AN INDEMNITY OR CONTRIBUTION OBLIGATION UNDER SECTIONS 12.01 OR 12.02 APPLIES, IN NO EVENT, WHETHER BASED ON CONTRACT, INDEMNITY, WARRANTY, STATUTE, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR OTHERWISE, SHALL ANY PARTY BE LIABLE FOR SPECIAL, INCIDENTAL, EXEMPLARY, INDIRECT, PUNITIVE, OR CONSEQUENTIAL DAMAGES, INCLUDING LOSS OF PROFITS OR REVENUE, LOSS OF USE OF THE TRANSMISSION LINE OR ANY ASSOCIATED EQUIPMENT, COST OF CAPITAL, COSTS IN EXCESS OF ESTIMATES, COST OF PURCHASED POWER OR TRANSMISSION, COST OF SUBSTITUTE EQUIPMENT, FACILITIES OR SERVICES, DOWNTIME COSTS OR CLAIMS OF CUSTOMERS OR LENDERS. THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES SHALL BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY PARTY. FOR THE AVOIDANCE OF DOUBT, NOTHING IN THIS SECTION 12.03(a) SHALL IN ANY MANNER LIMIT OR OTHERWISE RESTRICT (i) THE OBLIGATION OF THE NVE

PARTIES TO PAY THE MONTHLY PAYMENT IN ACCORDANCE WITH SECTION 3.06 OR (ii) A PARTY FROM COLLECTING ANY AMOUNT VALIDLY OWING UNDER AND CALCULATED IN ACCORDANCE WITH SECTIONS 2.02(e), 5.07, 16.02(d), (e), (g) AND (h), AND 16.04.

(b) IN NO EVENT SHALL THE MANAGING PARTY (IN RESPECT OF ON LINE), EITHER NVE PARTY (IN RESPECT OF THE TRANSMISSION LINE) OR GREAT BASIN (IN RESPECT OF THE GREAT BASIN SEGMENTS) BE LIABLE UNDER THIS AGREEMENT FOR ANY LOSS OR DAMAGE WHATSOEVER ARISING FROM THE FAILURE TO DISCOVER DEFECTS INHERENT IN THE DESIGN OF ON LINE OR THE EQUIPMENT COMPRISING ON LINE (IN THE CASE OF THE MANAGING PARTY OR EITHER NVE PARTY) OR THE GREAT BASIN SEGMENTS OR THE EQUIPMENT COMPRISING THE GREAT BASIN SEGMENTS (IN THE CASE OF GREAT BASIN OR EITHER NVE PARTY).

(c) EXCEPT FOR ANY JUDGMENT DEBT FOR DAMAGE RESULTING FROM WILLFUL MISCONDUCT/GROSS NEGLIGENCE OR EXCEPT TO THE EXTENT ANY JUDGMENT DEBT IS COLLECTIBLE FROM INSURANCE PROCEEDS, NONE OF THE MANAGING PARTY (IN ITS CAPACITY AS SUCH), EITHER NVE PARTY (IN ITS CAPACITY AS OPERATOR OF THE TRANSMISSION LINE, MAINTAINER OF ON LINE OR IN CONNECTION WITH ITS OBLIGATIONS UNDER SECTIONS 13.04 AND 14.04) AND GREAT BASIN (IN ITS CAPACITY AS MAINTAINER OF THE GREAT BASIN SEGMENTS OR IN CONNECTION WITH ITS OBLIGATIONS UNDER SECTIONS 13.06 AND 14.06) SHALL BE LIABLE FOR ANY CLAIMS WHETHER OR NOT RESULTING FROM SUCH PERSON’S NEGLIGENCE, OR THE NEGLIGENCE OF ITS OFFICERS, DIRECTORS, EMPLOYEES OR AGENTS, OR ANY PERSON OR ENTITY WHOSE NEGLIGENCE WOULD BE IMPUTED TO SUCH PERSON, ARISING IN CONNECTION WITH THE PERFORMANCE OR NON-PERFORMANCE OF ANY OF ITS OBLIGATIONS AS THE MANAGING PARTY, AS THE OPERATOR OF THE TRANSMISSION LINE OR AS MAINTAINER OF ON LINE OR UNDER SECTIONS 13.04 OR 14.04, OR AS THE MAINTAINER OF THE GREAT BASIN SEGMENTS OR UNDER SECTIONS 13.06 OR 14.06 (AS APPLICABLE) UNDER THIS AGREEMENT OR ANY ON LINE AGREEMENT OR ANY MAINTENANCE AGREEMENT IN RESPECT OF THE GREAT BASIN SEGMENTS, EXCEPT THE OBLIGATION TO PROVIDE EACH PARTY WITH ITS CAPACITY ENTITLEMENT (SUBJECT TO THE TERMS OF THIS AGREEMENT) FOLLOWING THE RESOLUTION OF ANY DISPUTE UNDER SECTION 19.02 REGARDING SUCH OBLIGATION.

(d) A CLAIM BASED ON WILLFUL MISCONDUCT/GROSS NEGLIGENCE MUST BE PERFECTED BY SUBMITTING A NOTICE UNDER SECTION 19.02(a) WITHIN TWO (2) YEARS AFTER THE LATER OF (A) THE DATE ON WHICH THE WILLFUL MISCONDUCT/GROSS NEGLIGENCE OCCURS, AND (B) THE DATE ON WHICH THE CLAIMING PARTY FIRST DISCOVERS OR OUGHT REASONABLY TO HAVE FIRST DISCOVERED THE OCCURRENCE OF THE WILLFUL MISCONDUCT/GROSS NEGLIGENCE. ALL CLAIMS MADE AFTER

SUCH TIME RELATING TO THE SAME WILLFUL MISCONDUCT/GROSS NEGLIGENCE WILL BE BARRED BY THIS SECTION 12.03(d). IF A JUDGMENT DEBT AGAINST THE MANAGING PARTY (IN ITS CAPACITY AS SUCH), EITHER NVE PARTY (IN ITS CAPACITY AS OPERATOR OF THE TRANSMISSION LINE, MAINTAINER OF ON LINE OR IN CONNECTION WITH ITS OBLIGATIONS UNDER SECTIONS 13.04 AND 14.04) OR GREAT BASIN (IN ITS CAPACITY AS MAINTAINER OF THE GREAT BASIN SEGMENTS OR IN CONNECTION WITH ITS OBLIGATIONS UNDER SECTIONS 13.06 AND 14.06) IS OBTAINED BY A PARTY AND IS COLLECTIBLE FROM INSURANCE PROCEEDS, SUCH PARTY SHALL NOT EXECUTE, LEVY OR OTHERWISE ENFORCE THE JUDGMENT (INCLUDING RECORDING OR EFFECTING A JUDGMENT LIEN) AGAINST SUCH PERSON (IN SUCH CAPACITY) OR ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS AGAINST WHOM THE JUDGMENT WAS OBTAINED TO THE EXTENT OF SUCH COLLECTABILITY.

(e) NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IN NO EVENT SHALL ANY NVE PARTY BE LIABLE OR IN DEFAULT UNDER THIS AGREEMENT FOR ANY ACT OR OMISSION UNDERTAKEN IN ITS CAPACITY AS A TRANSMISSION OR INTERCONNECTION PROVIDER OR A GENERATION OWNER.

(f) NONE OF THE MANAGING PARTY (IN ITS CAPACITY AS SUCH), EITHER NVE PARTY (IN ITS CAPACITY AS OPERATOR OF THE TRANSMISSION LINE, MAINTAINER OF ON LINE OR IN CONNECTION WITH ITS OBLIGATIONS UNDER SECTIONS 13.04 AND 14.04) AND GREAT BASIN (IN ITS CAPACITY AS MAINTAINER OF THE GREAT BASIN SEGMENTS OR IN CONNECTION WITH ITS OBLIGATIONS UNDER SECTIONS 13.06 AND 14.06) SHALL BE IN BREACH OF THIS AGREEMENT TO THE EXTENT IT RESULTS FROM ANOTHER PARTY’S BREACH OF THIS AGREEMENT.

12.04 Survival of Representations and Warranties.

(b) Notwithstanding anything to the contrary contained in this Agreement, Great Basin’s maximum aggregate liability for Claims which may be recovered for breaches of representations or warranties contained in Sections 17.02(b)-(d) pursuant to Section 12.01(a)(ii) shall be an amount equal to the net amount set forth on the Closing Statement; provided, however, that there shall be no maximum aggregate liability in connection with Claims for gross negligence, willful misconduct or fraud.

ARTICLE XIII

INSURANCE AND EVENTS OF LOSS

13.01 Insurance. Each Party shall maintain or cause to be maintained insurance of the types, in the amounts and with the deductibles specified in the Insurance Plan, as it may be amended by the Management Committee from time to time.

13.02 Damage or Destruction. The Parties shall, promptly after any Event of Loss, determine whether the Event of Loss exceeds the applicable Loss Threshold. If the Parties reasonably determine that the estimated cost or cost and time, as applicable, to repair or replace the Transmission Line (or the applicable portion thereof) following an Event of Loss will exceed any applicable Loss Threshold, then, with respect to an Event of Loss affecting ON Line, the Parties shall initiate the Wind-Up Events unless the Parties decide to repair or replace ON Line (or the applicable portion thereof).

Execution Version

13.03 Distribution of Insurance Proceeds. If the Parties reasonably determine that the estimated cost or cost and time to repair or replace ON Line (or any portion thereof) following an Event of Loss will not exceed any applicable Loss Threshold, or if the Parties reasonably determine that the estimated cost or cost and time to repair or replace ON Line (or the applicable portion thereof) following an Event of Loss will exceed an applicable Loss Threshold but the Parties agree to repair or replace ON Line (or the applicable portion thereof), then any Insurance Proceeds received by a Party in respect of such Event of Loss with respect to ON Line, to the extent there are any, shall be used to repair or replace ON Line (or the applicable portion thereof); provided that in the event the Insurance Proceeds exceed the actual repair and replacement costs (the “Excess Insurance Proceeds”), such Excess Insurance Proceeds shall be distributed to the NVE Parties. If (a) the Parties initiate the Wind-Up Events under Section 13.02 or (b) one Party purchases the Ownership Interests of any other Party under Section 13.05(a), any Insurance Proceeds shall be distributed to each Party in proportion to the aggregate percentage of Total Costs paid by such Party as of the time such Insurance Proceeds are received (prior to giving effect to any Transfer contemplated by Section 13.05(a)) to the extent (if applicable) any such Insurance Proceeds are not needed to pay any costs incurred in connection with the retirement of ON Line. If any Insurance Proceeds related to ON Line are received by a Party after termination of this Agreement, then any such Insurance Proceeds shall be promptly paid to the other Parties to the extent contemplated by this Section 13.03; provided, however, that (a) if this Agreement is terminated following consummation of a transaction whereby the NVE Parties have purchased Great Basin’s Ownership Interests for a price determined in accordance with Section 16.02(d) or Schedule 5, Great Basin shall promptly pay any Insurance Proceeds it receives following such termination to the NVE Parties, and (b) if this Agreement is terminated following consummation of any other transaction involving the purchase by Great Basin of all of the NVE Parties’ Ownership Interests or the purchase by one or both of the NVE Parties of all of Great Basin’s Ownership Interests, and the Insurance Proceeds in question are reflected in the purchase price, then the selling Party or Parties shall promptly pay any such Insurance Proceeds received following such termination to the acquiring Party or Parties.

13.04 Payment of Restoration Costs. If the Parties reasonably determine that the estimated cost or cost and time, as applicable, to repair or replace ON Line (or any portion thereof) following an Event of Loss will not exceed any applicable Loss Threshold, or if the Parties reasonably determine that the estimated cost or cost and time, as applicable, to repair or replace ON Line (or the applicable portion thereof) following an Event of Loss will exceed an applicable Loss Threshold but the Parties agree to repair or replace ON Line (or the applicable portion thereof), then (a) NPC shall promptly create a new budget for the reconstruction of ON Line consistent with the determination by the Parties of the estimated cost or time to repair or replace ON Line (or any portion thereof), subject to the approval of the Management Committee (the “Event of Loss Budget”), (b) NPC shall proceed under the Management Committee’s supervision to cause the repair and replacement of ON Line (or the applicable portion thereof) and (c) the NVE Parties shall pay for any repair and replacement costs not otherwise paid for by Insurance Proceeds (“Event of Loss Costs”) in accordance with the Event of Loss Budget. Great Basin shall elect or not elect to fund the Event of Loss Costs at or before Management Committee approval of the Event of Loss Budget. If Great Basin does not timely elect to fund any such Event of Loss Costs, Great Basin shall have no right or obligation to fund its Ownership Percentage of any such Event of Loss Costs. If Great Basin does timely elect (such

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

election being irrevocable) to fund its Ownership Percentage of any such Event of Loss Costs, then Great Basin shall timely fund its Ownership Percentage of any such Event of Loss Costs, and the amount funded by Great Basin in respect of Event of Loss Costs shall be reflected in the Monthly Payment, as provided in Section 3.06. To the extent that Great Basin does not timely fund its Ownership Percentage of any Event of Loss Costs, the NVE Parties may fund any such portion, and, within fifteen (15) days after receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties, each Party’s Ownership Percentage shall be adjusted such that, following the adjustment, such Party’s Ownership Percentage shall equal a ratio (x) the numerator of which is equal to the portion of the Total Costs paid by such Party and (y) the denominator of which equals the Total Costs, and Great Basin shall Transfer the portion of its Ownership Interest corresponding to its excess above its revised Ownership Percentage to the NVE Parties free and clear of any Liens other than Permitted Liens. Great Basin shall execute and record any bills of sale, deeds, certificates, memorandum and other documentation as reasonably requested by the NVE Parties to evidence the re-allocation of such interests. Great Basin shall make Applicable Transfer Representations and Warranties in connection with such Transfer. Notwithstanding anything to the contrary in this Agreement, neither NPC nor SPPC shall be required to pay for any Event of Loss Costs that are not in accordance with the applicable Event of Loss Budget.

13.05 Rebuild or Repair by a Single Party; Fair Market Value.

(a) If, following an Event of Loss with respect to ON Line that the Parties reasonably determine will exceed any applicable Loss Threshold, any Party (a “Withdrawing Party”) desires to retire ON Line (or the applicable portion thereof) and any other Party desires to rebuild, repair or replace ON Line (or the applicable portion thereof), then any Party desiring to rebuild, repair or replace ON Line (or the applicable portion thereof) shall have the right to purchase any Withdrawing Party’s Ownership Interests by delivery to the Parties of written notice within thirty (30) days after such determination. Upon receiving such written notice from a Party, each Withdrawing Party shall Transfer its Ownership Interests to such continuing Party free and clear of any Liens other than Permitted Liens on a date no later than fifteen (15) days from receipt of such written notice and receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties, and such continuing Party shall pay to each Withdrawing Party an amount equal to the Fair Market Value of such Withdrawing Party’s Ownership Interest. Each Withdrawing Party shall make Applicable Transfer Representations and Warranties to each continuing Party in connection with such Transfer.

(b) For the purposes of this Agreement, “Fair Market Value” means the cash price at which a willing seller would sell and a willing buyer would buy the applicable Ownership Interests, each being apprised of all relevant facts, as determined pursuant to the provisions of this Section 13.05(b). In order to determine the Fair Market Value, the NVE Parties and Great Basin shall each, within fifteen (15) Business Days after the transferring Party’s receipt of the notice of the acquisition, designate a qualified appraiser. A qualified appraiser shall be an appraiser with at least five (5) years of experience in the appraisal of properties similar to ON Line. If the NVE Parties or Great Basin fails to select an appraiser within such fifteen (15)-Business Day period, then the selected appraiser shall, within fifteen

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

(15) days thereafter, appoint a second appraiser with similar qualifications (who shall not have performed any work for the Party having selected the selected appraiser or its Affiliates within the five (5)-year period immediately prior to his or her appointment) who shall be deemed to have been appointed by the Party that failed to select an appraiser. Each of the two (2) appraisers shall be directed to determine the Fair Market Value of the transferring Party’s Ownership Interests within thirty (30) days of the appointment of the second appraiser and to notify each Party of his or her determination. If the lower of the two (2) determinations is not less than ninety-five percent (95%) of the higher of the two (2) determinations, then the Fair Market Value shall be the average of the two (2) determinations and such amount shall be binding upon the Parties. If the lower of the two (2) determinations is less than ninety-five percent (95%) of the higher of the two (2) determinations, then the two (2) appraisers shall, within fifteen (15) days thereafter, appoint a third appraiser with similar qualifications (who shall not have performed any work for any Party or its Affiliates within the five (5)-year period immediately prior to his or her appointment) and shall each furnish to such third appraiser a written report of his or her respective determination. Within thirty (30) days of his or her appointment, the third appraiser shall select the Fair Market Value of one or the other of the original appraisers and shall notify each Party of his or her determination, which shall be binding upon the Parties. The third appraiser must select one (1) of the two (2) appraisals and shall not have the right to establish a different Fair Market Value determination. The NVE Parties and Great Basin shall bear the cost of the appraiser appointed by each such Party (or deemed appointed by each such Party), and the NVE Parties and Great Basin shall each bear fifty percent (50%) of the cost of the third appraiser (if any). Notwithstanding anything to the contrary herein, the NVE Parties or Great Basin may request a new determination for Fair Market Value if the Transfer of Ownership Interest occurs nine (9) months or more after the completion of any appraisal previously used by the Parties to determine Fair Market Value.

13.06 Great Basin Segment Event of Loss. Great Basin shall promptly after any Event of Loss affecting all or any portion of the Great Basin Segments notify the Management Committee of such Event of Loss. If such Event of Loss does not exceed a Loss Threshold for the Great Basin Segments, then Great Basin shall promptly repair and replace the Great Basin Segments (or the applicable portion thereof) at its own cost. If such Event of Loss does exceed a Loss Threshold for the Great Basin Segments, as reasonably determined by the Parties, then Great Basin may rebuild and replace the Great Basin Segments (or any applicable portion thereof) at its own expense. Any Insurance Proceeds paid in respect of the Great Basin Segments shall be paid to Great Basin.

13.07 Event of Loss Threshold Deadlock. If a Loss Threshold Deadlock arises regarding any Event of Loss, such Loss Threshold Deadlock shall be referred to a panel consisting of a senior executive (President or Vice President) of each Party with the authority to resolve the Loss Threshold Deadlock. If such Loss Threshold Deadlock is not resolved for any reason within fifteen (15) days after the panel of senior executives has convened or within thirty (30) days after the Loss Threshold Deadlock occurred, whichever occurs sooner, then resolution of such Loss Threshold Deadlock shall be determined using the procedures in this Section 13.07. The Loss Threshold Deadlock shall be determined by a qualified independent engineer selected by the Parties. If the Parties are unable to select a qualified independent engineer within fifteen (15) days after any Party has proposed a qualified independent engineer, any Party may submit

the selection of such qualified independent engineer to the AAA. The qualified independent engineer shall have significant experience regarding the Loss Threshold Deadlock matter and shall not have worked for any Party or an Affiliate thereof within five (5) years preceding appointment thereof and shall make the determination within thirty (30) days after appointment, or as soon thereafter as is practicable. The Parties shall reasonably cooperate with the qualified independent engineer, and their agreement to submit Loss Threshold Deadlocks under this Section 13.07 to the qualified independent engineer shall be enforceable as an agreement to arbitrate. The decision of the qualified independent engineer shall be final, binding and conclusive upon the Parties, shall not be subject to challenge or appeal, and may be enforced in any court having jurisdiction in the same manner as an arbitral award.

ARTICLE XIV

CONDEMNATION

14.01 Participation in Condemnation Action. Each Party shall have the right, at its own cost and expense, to appear in any Condemnation Action and to participate in any and all hearings, trials and appeals therein. No Party shall accept or agree to any conveyance in lieu of any Condemnation Action unless agreed upon by the Parties.

14.02 Taking. If title to all or any part of the Transmission Line shall be taken in any Condemnation Action, other than for a temporary use or occupancy, the Parties shall, promptly after such Condemnation Action, determine whether the Condemnation Action exceeds the applicable Loss Threshold. If the Parties reasonably determine that the estimated cost or cost and time, as applicable, to replace the Transmission Line (or any portion thereof) following a Condemnation Action will exceed any applicable Loss Threshold (a “Complete Taking”), then, with respect to a Condemnation Action affecting ON Line, the Parties shall initiate the Wind-Up Events unless the Parties decide to replace the affected ON Line assets. ON Line shall not be wound-up as a result of a Condemnation Action that does not give rise to a Complete Taking (a “Partial Taking”).

14.03 Distribution of Condemnation Awards. Upon the occurrence of a Partial Taking or upon the occurrence of a Complete Taking and the agreement of the Parties to continue ON Line activities, then any Condemnation Awards received by a Party in respect of such Partial Taking or Complete Taking, as applicable, shall be used to replace ON Line (or the applicable portion thereof); provided that in the event the Condemnation Award exceeds the actual restoration cost (the “Excess Condemnation Award”), such Excess Condemnation Award shall be distributed to the NVE Parties. If (a) the Parties initiate the Wind-Up Events under Section 14.02 or (b) one Party elects to purchase the Ownership Interests of any other Party under Section 14.05, any Condemnation Award shall be distributed to each Party in proportion to the aggregate percentage of Total Costs paid by such Party as of the time such Condemnation Award is received (prior to giving effect to any Transfer contemplated by Section 14.05) to the extent (if applicable) any such Condemnation Award is not needed to pay any costs incurred in connection with the retirement of ON Line. If any Condemnation Award with respect to ON Line is received by a Party after termination of this Agreement, then any such Condemnation Award shall be promptly paid to the other Parties to the extent contemplated by this Section 14.03; provided, however, that (a) if this Agreement is terminated following consummation of a

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

transaction whereby the NVE Parties have purchased Great Basin’s Ownership Interests for a price determined in accordance with Section 16.02(d) or Schedule 5, Great Basin shall promptly pay any Condemnation Award it receives following such termination to the NVE Parties, and (b) if this Agreement is terminated following consummation of any other transaction involving the purchase by Great Basin of all of the NVE Parties’ Ownership Interests or the purchase by one or both of the NVE Parties of all of Great Basin’s Ownership Interests, and the Condemnation Award in question is reflected in the purchase price, then the selling Party or Parties shall promptly pay any such Condemnation Award received following such termination to the acquiring Party or Parties.

14.04 Payment of Restoration Costs. Upon the occurrence of a Partial Taking or upon the occurrence of a Complete Taking and the agreement of the Parties to continue ON Line activities, then (a) NPC shall promptly create a new budget for the reconstruction of ON Line consistent with the determination by the Parties of the estimated cost or cost and time to replace ON Line (or any portion thereof), subject to the approval of the Management Committee (the “Condemnation Action Budget”), (b) NPC shall proceed under the Management Committee’s supervision to cause the replacement of the affected portion of ON Line and (c) the NVE Parties shall pay for any replacement costs not otherwise paid for by Condemnation Award (“Condemnation Action Costs”) in accordance with the Condemnation Action Budget. Great Basin shall elect or not elect to fund the Condemnation Action Costs at or before Management Committee approval of the Condemnation Action Budget. If Great Basin does not timely elect to fund any such Condemnation Action Costs, Great Basin shall have no right or obligation to fund its Ownership Percentage of any such Condemnation Action Costs. If Great Basin does timely elect (such election being irrevocable) to fund its Ownership Percentage of any such Condemnation Action Costs, then Great Basin shall timely fund its Ownership Percentage of any such Condemnation Action Costs, and the amount funded by Great Basin in respect of Condemnation Action Costs shall be reflected in the Monthly Payment, as provided in Section 3.06. To the extent that Great Basin does not timely fund its Ownership Percentage of any Condemnation Action Costs, the NVE Parties may fund any such portion, and, within fifteen (15) days after receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties, each Party’s Ownership Percentage shall be adjusted such that, following the adjustment, such Party’s Ownership Percentage shall equal a ratio (x) the numerator of which is equal to the portion of the Total Costs paid by such Party and (y) the denominator of which equals the Total Costs, and Great Basin shall Transfer the portion of its Ownership Interest corresponding to its excess above its revised Ownership Percentage to the NVE Parties free and clear of any Liens other than Permitted Liens. Great Basin shall execute and record any bills of sale, deeds, certificates, memorandum and other documentation as reasonably requested by the NVE Parties to evidence the re-allocation of such interests. Great Basin shall make Applicable Transfer Representations and Warranties in connection with such Transfer. Notwithstanding anything to the contrary in this Agreement, neither NPC nor SPPC shall be required to pay for any Condemnation Action Costs that are not in accordance with the applicable Condemnation Action Budget.

14.05 Rebuild or Repair by a Single Party. If, following a Complete Taking as reasonably determined by the Parties, any Party desires to retire ON Line and any other Party desires to rebuild or replace the condemned portion of ON Line, then the Party

desiring to rebuild or replace the condemned portion of ON Line shall have the right to purchase any Withdrawing Party’s Ownership Interests by delivery to the other Parties of written notice within thirty (30) days after such Management Committee determination.

Each Withdrawing Party shall make Applicable Transfer Representations and Warranties to each continuing Party in connection with such Transfer.

14.06 Great Basin Segment Condemnation. Great Basin shall promptly after any Condemnation Action affecting all or any portion of the Great Basin Segments notify the Management Committee of such Condemnation Action. If such Condemnation Action does not exceed a Loss Threshold for the Great Basin Segments, then Great Basin shall promptly rebuild and replace the Great Basin Segments (or the applicable portion thereof) at its own cost. If such Condemnation Action does exceed a Loss Threshold for the Great Basin Segments, as reasonably determined by the Parties, then Great Basin may rebuild and replace the Great Basin Segments (or any applicable portion thereof) at its own expense. Any Condemnation Awards paid in respect of the Great Basin Segments shall be paid to Great Basin.

14.07 Condemnation Action Threshold Deadlock. If a Loss Threshold Deadlock arises regarding any Condemnation Action, such Loss Threshold Deadlock shall be referred to a panel consisting of a senior executive (President or Vice President) of each Party with the authority to resolve the Loss Threshold Deadlock. If such Loss Threshold Deadlock is not resolved for any reason within fifteen (15) days after the panel of senior executives has convened or within thirty (30) days after the Loss Threshold Deadlock occurred, whichever occurs sooner, then resolution of such Loss Threshold Deadlock shall be determined using the procedures in this Section 14.07. The Loss Threshold Deadlock shall be determined by a qualified independent engineer selected by the Parties. If the Parties are unable to select a qualified independent engineer within fifteen (15) days after any Party has proposed a qualified independent engineer, any Party may submit the selection of such qualified independent engineer to the AAA. The qualified independent engineer shall have significant experience regarding the Loss Threshold Deadlock matter and shall not have worked for any Party or an Affiliate thereof within five (5) years preceding appointment thereof and shall make the determination within thirty (30) days after appointment, or as soon thereafter as is practicable. The Parties shall reasonably cooperate with the qualified independent engineer, and their agreement to submit Loss Threshold Deadlocks under this Section 14.07 to the qualified independent engineer shall be enforceable as an agreement to arbitrate.

TRANSFERS AND CHANGES OF CONTROL

15.01 Transfers.

(a) Except for Permitted Transfers, no Party may Transfer all or any portion of its Ownership Interests or its rights or obligations under this Agreement without the prior written approval of the other Parties, which approval shall not be unreasonably withheld, conditioned or delayed. Except for Permitted Transfers, Great Basin shall not Transfer any ownership interest in the Great Basin Segments without the prior written approval of the other Parties, which approval shall not be unreasonably withheld, conditioned or delayed. For purposes of this Section 15.01, any grounds that are reasonably likely to have a material adverse effect on a non-Transferring Party, any proposed Transfer of less than all of a Party’s Ownership Interests and any proposed Transfer of less than all of Great Basin’s ownership interests in the Great Basin Segments, in each case shall constitute reasonable grounds for withholding or conditioning approval and shall be described to the Transferring Party in reasonable detail if such approval is withheld or conditioned.

(b) No Transfer of Ownership Interests or any rights or obligations under this Agreement shall be permitted, or shall become effective, unless such Transfer includes a corresponding and equivalent Transfer of all associated rights and obligations of the Transferring Party in its Ownership Interests and this Agreement. No Transfer of ownership interests in the Great Basin Segments or any rights or obligations under this Agreement with respect thereto shall be permitted, or shall become effective, unless such Transfer includes a corresponding and equivalent Transfer of all associated rights and obligations of Great Basin in its ownership interests in the Great Basin Segments and this Agreement.

(c) Any Party may allow any of its transmission or other customers to transmit electricity on or otherwise utilize its Electrical Capacity, Fiber Optic Capacity or Microwave Capacity pursuant to ordinary course transactions entered into in accordance with such Party’s Open Access Transmission Tariff without the prior written consent of the other Parties; provided, that such customers utilize such capacity in accordance with the terms of this Agreement. Any exercise by a Party of its rights under this Section 15.01(c) shall not relieve such Party of its obligations under this Agreement.

(d) Any Transfer that is made in violation of this Agreement shall be void ab initio.

15.02 Right of First Refusal and Right of First Offer.

(a) ROFR.

(i) If any Party receives an unsolicited offer (other than an offer that, if consummated, would constitute a Permitted Transfer pursuant to Sections 15.03(a)-(g)) from a non-Affiliated third-Person to Transfer all or part of its Ownership Interests, the Transferring Party may make such Transfer only if it has complied with the provisions of this Section 15.02 and such Transfer is made in accordance with the other

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

requirements of this Article XV. Prior to making such Transfer, the Transferring Party shall give to the other Parties written notice (except a Party that, at the time, is in default under Sections 16.01(a), (f) or (g)) of the proposed transaction (the “ROFR Offer Notice”), which notice shall fully disclose (A) the terms of the proposed transaction, (B) the Ownership Interests subject to the ROFR Offer Notice (the “ROFR Offered Interest”), (C) the identity of the proposed transferee and (D) the date on which the offer shall expire if not accepted, which shall be at least thirty (30) days after each other Party has received the ROFR Offer Notice (the “ROFR Offer Deadline”).

(ii) Upon receipt of a ROFR Offer Notice, any Party receiving such notice shall have a right to acquire all (but not less than all) of the ROFR Offered Interest, upon the same terms and conditions that are set forth in the ROFR Offer Notice, by giving written notice to the Transferring Party on or prior to the ROFR Offer Deadline stating that it elects to acquire the ROFR Offered Interest (the “ROFR Return Notice”), which election may be subject to receipt of PUCN Approval and any required Governmental Approvals on terms acceptable to the NVE Parties. A failure to give the ROFR Return Notice by the ROFR Offer Deadline shall be deemed to be an election not to acquire the ROFR Offered Interest and, if both other Parties elect not to acquire the ROFR Offered Interest, subject to the Transferring Party’s compliance with the provisions of Section 15.01, Sections 15.02(a) and (d) and Section 15.04, the ROFR Offered Interest may be thereafter Transferred to the non-Affiliated third-Person as long as the terms of such Transfer are the same as, or more favorable to the Transferring Party than, those described in the ROFR Offer Notice.

(b) ROFO.

(i) Except with respect to any Transfer that, if consummated, would constitute a Permitted Transfer pursuant to Sections 15.03(a)-(g) and any Transfer subject to Section 15.02(a), a Transferring Party may make a Transfer of any Ownership Interests only if it has complied with the requirements of this Section 15.02 and such Transfer is made in accordance with the other requirements of this Article XV. Prior to initiating any auction or sales process, the Transferring Party shall give to the other Parties written notice (except a Party that, at the time, is in default under Sections 16.01(a), (f) or (g)) of the proposed transaction (the “ROFO Offer Notice”) setting forth the Ownership Interests the Transferring Party proposes to Transfer (the “ROFO Offered Interest”).

(ii) Upon receipt of an ROFO Offer Notice, any Party receiving such notice shall have a right to negotiate with the Transferring Party for the purchase of the ROFO Offered Interests by giving written notice to the Transferring Party within thirty (30) days after receipt of the ROFO Offer Notice (the “ROFO Offer Deadline”) stating that it elects to negotiate to acquire the ROFO Offered Interest (the “ROFO Return Notice”). Upon any timely delivery of a ROFO Return Notice by any Party, such Party and the Transferring Party shall negotiate exclusively and in good faith for forty-five (45) days, unless otherwise agreed by those Parties, the terms of the Transfer of the ROFO Offered Interests. A failure to give the ROFO Return Notice by the ROFO

Transmission Use and Capacity Exchange Agreement

Privileged and Confidential

Execution Version

Offer Deadline shall be deemed to be an election not to negotiate to acquire the ROFO Offered Interest and, if both other Parties elect not to negotiate to acquire the ROFO Offered Interest or the applicable Parties do not agree on the Transfer of the ROFO Offered Interests within such forty-five (45) day period, subject to the Transferring Party’s compliance with the provisions of Section 15.01, Sections 15.02(b) and (d) and Section 15.04, the ROFO Offered Interest may be thereafter Transferred.

(c) Acquisition. If a Party elects to exercise its right to acquire any ROFR Offered Interest or the Transferring Party and any other Party agree to a Transfer of any ROFO Offered Interest to any such other Party, then the acquiring Party (the “Acquiring Party”) and the Transferring Party shall execute such instruments as may be necessary and appropriate to effectuate the Transfer of the applicable Offered Interests as soon as practicable to the Acquiring Party, free and clear of all Liens (i) in the case of ROFR Offered Interests, which are not by the terms of the ROFR Offer Notice specifically identified as surviving the Transfer of the ROFR Offered Interest and (ii) in the case of ROFO Offered Interest, other than Permitted Liens. The Acquiring Party shall close on the acquisition of the applicable Offered Interests within fifteen (15) days after (i) in the case of ROFR Offered Interests, the Transferring Party has satisfied all conditions precedent contained in the ROFR Offer Notice and (ii) the Acquiring Party has received PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties. The Transferring Party shall make the following representations and warranties to the Acquiring Party in connection with such Transfer: (i) in the case of ROFR Offered Interests, the representations and warranties set forth in the applicable ROFR Offer Notice, and (ii) in the case of ROFO Offered Interests, Applicable Transfer Representations and Warranties. Failure to close on the acquisition of the applicable Offered Interests within such time period shall be deemed to be a rejection of the ROFR Offer Notice or ROFO Offer Notice, as applicable, if such failure is solely attributable to the Acquiring Party.

(d) Reattachment of Transfer Restrictions. The right of the Transferring Party to Transfer Offered Interests shall once again be subject to the requirements of this Section 15.02 as if the Transferring Party had never offered the Offered Interests to any non-Transferring Party if the Transferring Party (i) fails to consummate the Transfer of the Offered Interests to a third Person within (A) one hundred eighty (180) days after the date of the applicable Offer Notice or (B) if both Parties elect not to acquire the applicable Offered Interest, ninety (90) days after the later of such election or (ii) in the case of the ROFR Offered Interests, undertakes to, without the written consent of each other Party, Transfer such ROFR Offered Interests to Persons other than those Persons whose identity was disclosed in the ROFR Offer Notice, which consent will not be unreasonably withheld, conditioned or delayed, or upon terms and conditions less favorable to the Transferring Party than the terms and conditions than were contained in the ROFR Offer Notice.

15.03 Permitted Transfers. Although the following shall constitute a Transfer under this Agreement, no consent of any other Party shall be required for any of the following Transfers or corresponding and equivalent Transfers of this Agreement (each, a “Permitted Transfer”):

Each Assignment and Assumption Agreement shall (i) provide that the other Parties are each a third-Person beneficiary thereof, (ii) require that the transferee becomes a party to this Agreement, each ON Line Agreement (with respect to a Transfer of Ownership Interests) and each Security Document and agrees to be bound by the terms hereof and, if applicable, thereof, (iii) reflect, among other things, that the transferee’s Ownership Interests or ownership interests in the Great Basin Segments, as applicable, are subject to the terms and provisions of this Agreement, each ON Line Agreement (with respect to a Transfer of Ownership Interests ) and each Security Document and that such transferee has no greater rights in ON Line or the Great Basin Segments, as applicable, than the Transferring Party prior to the Transfer and (iv) contain representations and warranties from the transferee substantially similar to those set forth in Section 17.01.

Each such event shall constitute an Event of Default by Great Basin.

16.02 Remedies.

(a) Remedies Not Exclusive. Except as provided in Section 11.03(b) or any other provision of this Agreement that expressly provides for a specific remedy in the event of a breach of such provision, upon the occurrence of an Event of Default by a Party, the non-defaulting Parties shall have available all remedies hereunder, as well as all legal and equitable remedies, including those available in order to enforce payment of any amounts or performance of any obligations, and no remedy conferred upon or reserved by a Party is intended to be exclusive of any other remedy or remedies available hereunder or that now or hereafter exists at law or in equity, each and every such remedy shall be cumulative and shall be in addition to every other such remedy.

(b) Injunctive Relief and Specific Performance. Each Party acknowledges and agrees that the failure to perform any of its respective obligations under this Agreement would cause irreparable harm to the other Parties and that the remedy at law for any violation or threatened violation thereof would be inadequate, and further agrees that the other Parties shall be entitled to a temporary or permanent injunction, specific performance or other

Privileged and Confidential

Execution Version

equitable relief specifically to enforce such obligations without the necessity of proving the inadequacy of its legal remedies. No Party shall be required to post any guaranty, letter of credit, bond or other security to obtain an order or decree of specific performance.

(c) Loss of Voting Rights. If an Event of Default by a Party has occurred under Section 16.01(a), Section 16.01(g) due to the failure of the ON Line Security Interest or GB Segment Security Interest to be valid, legal, perfected and in full force and effect, or Section 16.01(b) with respect to the failure to provide the other Parties with their respective Capacity Entitlements, without limiting any other rights that the non-defaulting Parties might have, for so long as such Event of Default remains outstanding (i) the defaulting Party’s Authorized Representatives shall not have any right to decide, approve, authorize or vote on any matters before the Management Committee and (ii) the other Party’s Authorized Representatives shall be entitled to represent the defaulting Party with respect to all matters before the Management Committee and the quorum requirements under Section 8.01(f) shall be deemed satisfied.

(d) Purchase Right Upon Default. If (i) an Event of Default by a Party has occurred under Section 16.01(a) and the aggregate amount that remains unpaid by such Party exceeds five million Dollars ($5,000,000), (ii) an Event of Default has occurred by a Party under Section 16.01(b) with respect to the failure to provide the other Parties’ their respective Capacity Entitlements, (iii) an Event of Default has occurred under Section 16.01(g) due to the failure of the ON Line Security Interest or GB Segment Security Interest to be valid, legal, perfected and in full force and effect, in either case, and such event has occurred after the Acquisition Closing Date and is continuing, then, without limiting any other rights that the non-defaulting Parties might have, a non-defaulting Party may, upon written notice to the defaulting Party (the “Default Purchase Notice”) delivered while such Event of Default remains outstanding, purchase all of the Ownership Interests of the defaulting Party. Upon a non-defaulting Party providing the defaulting Party with the Default Purchase Notice, and, as the case may be, subject to the consent of the NVE Lenders to the extent required under the NVE Lenders’ financing and security agreements or the consent of the ON Line Lenders if the proceeds of the Transfer are less than the obligations owed by Great Basin to the ON Line Lenders, then the defaulting Party shall Transfer its Ownership Interest to such non-defaulting Party free and clear of any Liens other than Permitted Liens within fifteen (15) days after receipt of such notice and receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties. At the time such Transfer occurs, such non-defaulting Party shall pay to the defaulting Party an amount equal to the lower of (A) book value of the defaulting Party’s Ownership Interest on the date of the Default Purchase Notice and (B) the Fair Market Value of the defaulting Party’s Ownership Interest on the date of the Default Purchase Notice. The defaulting Party shall make Applicable Transfer Representations and Warranties in connection with such Transfer.

If an action by the Managing Party undertaken in connection with its management responsibilities results in an Event of Default or, upon the occurrence of the circumstances described in Section 5.03(e), then, without limiting any other rights that the Step-In Party might otherwise have, the Step-In

Privileged and Confidential

Party may, upon written notice to the Managing Party delivered at any time prior to the Managing Party having cured such default or, in the case of Section 5.03(e), at any time prior to the NVE Parties committing to fund their Ownership Percentage of such Initial Cost Differential or Incremental Cost Differential, assume the management of all ON Line Activities. If the Step-In Party exercises its rights provided in this Section 16.02(e)(i), the Step-In Party shall appoint its ON Line Manager in charge of the Managing Party’s responsibilities hereunder, and may retain such managerial responsibilities until ON Line COD or relinquish all or any part thereof from time to time to the Managing Party; provided, however, that the Managing Party may elect to reacquire management of the ON Line Activities, to the extent such management was the Managing Party’s responsibility prior to the exercise of the Step-In Party’s rights under this Section 16.02(e)(i), once the Managing Party has no Events of Default outstanding or commits to fund its Ownership Percentage of the Initial Cost Differential or Incremental Cost Differential, as applicable. Notwithstanding anything herein to the contrary, (A) any reasonable costs and expenses related to the Step-In Party’s exercise of its rights provided in this Section 16.02(e)(i) and (B) any reasonable incremental costs and expenses related to the Step-In Party’s assumption of the Managing Party’s responsibilities hereunder, shall be borne by the Managing Party.

(ii) Maintenance Step-In. If (A) after ON Line COD, ON Line (or a portion thereof) or (B) after the commercial operation of a Great Basin Segment, any Great Basin Segment (or a portion thereof), in either case, is materially impaired due to an Event of Default under Section 16.01(b) constituting Willful Misconduct/Gross Negligence by NPC or Great Basin in its role as maintainer of ON Line or the Great Basin Segments, as applicable, then, without limiting any other rights that the Step-In Party might otherwise have, the Step-In Party may, upon written notice to the defaulting Party delivered at any time prior to the defaulting Party having cured such Event of Default, assume management of the maintenance responsibilities on any portion of the Transmission Line for which the defaulting Party has maintenance responsibility and all responsibilities set forth in this Agreement related thereto. If the Step-In Party exercises its rights provided in this Section 16.02(e)(ii), the Step-In Party may retain such managerial responsibilities throughout the Term or relinquish all or any part thereof from time to time to the defaulting Party; provided, however, that the defaulting Party may elect to reacquire such management responsibility, to the extent such management was the defaulting Party’s responsibility prior to the exercise of the Step-In Party’s rights under this Section 16.02(e)(ii), once the defaulting Party has corrected the material impairment. Notwithstanding anything herein to the contrary, (X) any reasonable costs and expenses related to the Step-In Party’s exercise of its rights provided in this Section 16.02(e)(ii) and (Y) any reasonable incremental costs and expenses related to the Step-In Party’s assumption of the defaulting Party’s responsibilities hereunder, shall be borne by the defaulting Party; provided, that, in the event the Step-In Party retains an Independent Contractor or other third party to assume management of the maintenance responsibilities on any portion of the Transmission Line for which the defaulting Party has maintenance responsibility, such Independent Contractor or other third party shall be reasonably acceptable to the defaulting Party (such acceptance being without prejudice to the defaulting Party’s right to dispute the

Privileged and Confidential

amounts charged by such Independent Contractor or other third party). If a Step-In Party takes over the management of maintenance obligations from the defaulting Party pursuant to this Section 16.02(e)(ii), the Step-In Party shall indemnify the defaulting Party and its Affiliates for any fines, penalties or other charges levied against the defaulting Party and its Affiliates as a result of a failure to properly maintain the portion of the Transmission Line for which the Step-In Party assumed maintenance responsibility pursuant to this Section 16.02(e)(ii) during the period the Step-In Party has taken over the management of such maintenance (except to the extent such fines, penalties or other charges arise as a result of the Willful Misconduct/Gross Negligence of the defaulting Party and/or any of its Affiliates).

(iii) Operations Step-In. If, at any time after ON Line COD, the NVE Parties no longer qualify as public utilities under Nevada law and ON Line is materially impaired due to an Event of Default under Section 16.01(b) constituting Willful Misconduct/Gross Negligence by NPC, then, without limiting any other rights that Great Basin might otherwise have, Great Basin may, upon written notice to the NVE Parties delivered at any time prior to the defaulting Party having cured such Event of Default, assume management of the operation of the Transmission Line, including all Operating Activities, and all responsibilities set forth in this Agreement related thereto. If Great Basin exercises its rights provided in this Section 16.02(e)(iii), Great Basin may retain such managerial responsibilities throughout the Term or relinquish all or any part thereof from time to time to the NVE Parties. Notwithstanding anything herein to the contrary, (X) any reasonable costs and expenses related to Great Basin’s exercise of its rights provided in this Section 16.02(e)(ii) and (Y) any reasonable incremental costs and expenses related to the Great Basin’s assumption of the NVE Party’s responsibilities hereunder, shall be borne by the NVE Party; provided, that, in the event Great Basin retains a third party to assume management of the operation of the Transmission Line, such third party shall be reasonably acceptable to the defaulting Party (such acceptance being without prejudice to the defaulting Party’s right to dispute the amounts charged by such third party).

(f) Ownership Adjustment. If an Event of Default has occurred under Section 16.01(a), then, without limiting any other rights that the non-defaulting Parties might have, to the extent such Event of Default has not otherwise been satisfied in full upon the exercise by the non-defaulting Party of its rights under Section 16.02(g), a non-defaulting Party may, after the Acquisition Closing, upon written notice to the Parties delivered while such Event of Default remains outstanding, cause a reduction in the defaulting Party’s Ownership Percentage within fifteen (15) days after receipt of such notice and receipt of PUCN Approval and all required Governmental Approvals on terms acceptable to the NVE Parties, such that the defaulting Party’s Ownership Percentage equals a ratio (i) the numerator of which is equal to the portion of the Total Costs paid by the defaulting Party and (ii) the denominator of which equals the Total Costs, and the defaulting Party shall Transfer the portion of its Ownership Interest corresponding to its excess above its revised Ownership Percentage to each non-defaulting Party free and clear of any Liens other than Permitted Liens. Thereafter, each Party’s Capacity Entitlement shall automatically and proportionately increase or decrease, as applicable, with such Party’s increase or decrease of Ownership Interest. The defaulting Party shall execute and

record any bills of sale, deeds, certificates or other documentation as reasonably requested by any non-defaulting Party to evidence the re-allocation of such interests. The defaulting Party shall make Applicable Transfer Representations and Warranties in connection with such Transfer.

(g) Loss of Right to Revenue or Electrical Capacity. If an Event of Default has occurred under Section 16.01(a), then, without limiting any other rights that the non-defaulting Parties might have, to the extent such Event of Default has not otherwise been satisfied in full upon the exercise by the non-defaulting Party of its rights under Section 16.02(f), a non-defaulting Party may, upon fifteen (15) days’ prior written notice to the defaulting Party delivered while such Event of Default remains outstanding, recover the defaulted payments by temporarily receiving all or any part of the defaulting Party’s Capacity Entitlement. Receipt of the defaulting Party’s Capacity Entitlement shall continue until such time as the non-defaulting Party has received an amount equal to the payment default plus interest at the Default Rate, determined based on amounts that would otherwise be payable for such Capacity Entitlement under the applicable open access transmission tariff of the non-defaulting Party. Once such non-defaulting Party has received such additional amount, the defaulting Party shall immediately, and without further action by the Parties, be entitled to fully receive its Capacity Entitlement. In the event receipt of the defaulting Party’s Capacity Entitlement is not practicable due to regulatory requirements or the rights of third Persons, the defaulting Party shall pay over to the non-defaulting Party all proceeds, promptly upon the defaulting Party’s receipt of such proceeds, of the defaulting Party’s Capacity Entitlement until such time as the non-defaulting Party has received an amount equal to the payment default plus interest at the Default Rate.

(h) If an Event of Default of NPC has occurred under Section 16.01(a) in respect of one or more Contributions or payments and has continued for a period of one hundred twenty (120) days and the aggregate amount due and payable from NPC to Great Basin in respect of such Contributions or payments exceeds (x) from ON Line COD to the thirtieth (30th) anniversary of such date, five million Dollars ($5,000,000) and (y) from the thirtieth (30th) anniversary of ON Line COD to the forty-first (41st) anniversary of ON Line COD, one million Dollars ($1,000,000) (an “Extended Payment Default”), Great Basin shall possess the right to terminate the NVE Parties’ Capacity Entitlement other than the portion of their Capacity Entitlement on ON Line corresponding to their aggregate Ownership Interest (the “Terminated Capacity”) by sending written notice (by facsimile or other reasonable means) to NPC, which notice of termination shall become effective thirty (30) days after receipt if the NVE Parties fail to cure the Extended Payment Default prior to such thirtieth (30th) day. If Great Basin fails to exercise this right of termination within thirty (30) days following the time when the Extended Payment Default first accrues (or more than thirty (30) days if the Parties agree to an extension), then such right of termination shall no longer be available to Great Basin as a remedy for the defaulted Contributions and payments constituting such Extended Payment Default, but shall be available for subsequent defaulted Contributions and payments to the extent they satisfy the requirements for an Extended Payment Default. The termination of the Terminated Capacity and payment of the Termination Payment (if any) shall be the sole and exclusive remedy for Great Basin for the Extended Payment Default for the time period beginning at the time notice of termination under this Section 16.02(h) is transmitted; provided, however, that Great Basin may exercise any remedies available to it under this Section 16.02 prior to its transmittal of such

Transmission Use and Capacity Exchange Agreement

Execution Version

notice of termination. Great Basin shall calculate the payment associated with termination (“Termination Payment”) as follows:

(i) Any Loss shall be determined by comparing the value of the Terminated Capacity had it not been terminated plus Costs to the equivalent quantities and relevant market prices for the remaining term of the Monthly Payment Period either quoted by a bona fide third-party offer or which are reasonably expected to be available in the market under a replacement contract or contracts for such Terminated Capacity. To ascertain the market prices of a replacement contracts, Great Basin may consider, among other valuations, quotations from dealers in transmission capacity and other bona fide third party offers, all adjusted for the length of the remaining term. It is expressly agreed that Great Basin shall not be required to enter into replacement transactions in order to determine the Termination Payment.

(ii) Any Loss calculated under clause (i) shall be discounted to present value using the Present Value Rate as of the time of termination (to take account to the period between the time the termination was effective and when such amount would have otherwise been due pursuant to this Agreement). The “Present Value Rate” shall mean the sum of 0.50% plus the yield reported on page “USD” of the Bloomberg Financial Markets Services Screen (or, if not available, any other nationally recognized trading screen reporting on-line intraday trading in United States government securities) at 11:00 a.m. (New York City, New York time) for the United States government securities having a maturity that matches the average remaining term of the Monthly Payment Period; and

(iii) Great Basin shall aggregate any Loss with Outstanding Payments and notify NPC of such amount and the NVE Parties shall, within three (3) Business Days of receipt of such notice, pay to Great Basin an amount equal to the aggregate sum of the Loss (if any) and Outstanding Payments as the Termination Payment. The Termination Payment shall bear interest at the Present Value Rate from the time notice of termination was received until paid.

(iv) For purposes of this Section 16.02(h):

(A) “Loss” means the economic loss (inclusive of Costs), if any, resulting from the termination of the Terminated Capacity, determined in a commercially reasonable manner as calculated in accordance with this Section 16.02(h);

(B) “Costs” means brokerage fees, commissions and other similar transaction costs and expenses reasonably incurred in terminating any specifically related arrangements which replace the Terminated Capacity and reasonable attorneys’ fees, if any, incurred in connection with Great Basin enforcing its rights under this Section 16.02(h). Great Basin shall use reasonable efforts to mitigate or eliminate these Costs.

amount of payments due and owing under this Agreement (and not otherwise paid) by the NVE Parties to Great Basin as of the date on which the termination of the Terminated Capacity becomes effective (it being understood that payment of the Outstanding Payments to Great Basin shall be in satisfaction of the NVE Parties’ obligation to make such payments under this Agreement);

(D) In no event, however, shall a Party’s Loss, Costs or Outstanding Payments include any penalties or similar charges imposed by Great Basin.

(v) Notwithstanding anything in this Agreement to the contrary, upon the effectiveness of the notice terminating the Terminated Capacity (A) the NVE Parties’ Capacity Entitlement with respect to Electrical Capacity on ON Line shall be equal to the NVE Parties’ Ownership Percentage and the NVE Parties shall not be entitled to any Electrical Capacity on the Great Basin Segments, (B) all Operating Costs, Event of Loss Costs, Condemnation Action Costs and Capital Repair Costs shall be funded by the Parties in accordance with their respective Ownership Percentages and Great Basin shall have no right to recover Great Basin’s Ownership Percentage of any such costs from the NVE Parties and (C) the NVE Parties’ obligation to pay the Monthly Payment shall cease as provided in Section 3.06(c). Payment of the Termination Payment pursuant to this Section 16.02(h) shall cure any Event of Default and Extended Payment Default giving rise to Great Basin’s rights under this Section 16.02(h).

(i) Other Remedies. Prior to the Acquisition Closing Date and in the event the Acquisition Closing does not occur, breaches of representations and warranties and covenants shall be exclusively governed by Section 11.03. After the Acquisition Closing Date, breaches of representations and warranties shall be exclusively governed by Article XII, subject to the limitations set forth therein.

16.03 Additional Obligations. With respect to a Party as to which an Event of Default has occurred, such Party shall take any and all such further actions and shall execute and file where appropriate any and all such further legal documents and papers as may be reasonable under the circumstances resulting from such Event of Default in order to facilitate the carrying out of this Agreement or otherwise effectuate its purpose, including action to seek any required Governmental Approval and to obtain any other required consent, release, amendment or other similar document.

16.04 Interest on Overdue Payments and Contributions; Setoff. If any sum due hereunder is not paid or contributed by the due date thereof, the Party owing such obligation shall pay to the other Parties or to a Project Account, as applicable, interest thereon at the Default Rate concurrently with the payment of the amount, such interest to begin to accrue as of the due date of such payment or Contribution. Further, each non-defaulting Party shall have the right to setoff any amount owed to it by a defaulting Party hereunder against any amounts owed by it to such defaulting Party hereunder.

16.05 Mitigation. Each Party shall use commercially reasonable efforts to mitigate all of its damages and losses resulting from an Event of Default by any other Party.

To secure Great Basin’s obligations under this Agreement, the SNIP Agreement and all other agreements executed and delivered herewith (but only if and to the extent any such other agreements provide that they are to be so secured), unless the Parties agree in writing otherwise in their respective sole discretion, (i) at the Acquisition Closing, Great Basin shall grant to the NVE Parties a security interest in (A) all of Great Basin’s right, title and interest in, to and under ON Line (which shall initially constitute a seventy-five percent (75%) interest) and (B) all of its rights under this Agreement to the Monthly Payment and any rights related to ON Line (collectively, the “ON Line Security Interest”) and (ii) at GB Segment Financial Closing, Great Basin shall grant to the NVE Parties either (A) a security interest in all right, title and interest in, to and under the Great Basin Segments, provided that the amount that may be realized with respect to such security interest shall not exceed thirty-eight percent (38%) of the Anticipated Investments in the Great Basin Segments (the “GB Segment Security Interest Cap”) or (B) if Great Basin has made the Transfer contemplated by Section 15.03(f)(i), or such security interest can be granted under Applicable Law without such transfer and the NVE Parties consent in writing, a security interest in thirty-eight (38%) of all right, title and interest, in, to and under the Great Basin Segments and (C) a security interest in Great Basin’s rights under this Agreement related to the Great Basin Segments that corresponds to the security interest granted in clauses (A) and (B) above (collectively, the “GB Segment Security Interest”), in each case pursuant to the Security Documents; provided, however, that, for the avoidance of doubt, neither the ON Line Security Interest nor the GB Segment Security Interest shall include a Lien on any of Great Basin’s cash, accounts, securities, books and records (other than in respect of ON Line Agreements, corresponding agreements required for the construction and operation of the Great Basin Segments and Governmental Approvals), as more specifically described and agreed in such Security Documents; provided, further that prior to GB Segment COD, the GB Segment Security Interest shall only secure the obligations of Great Basin under this Agreement, the SNIP Agreement and all agreements executed and delivered herewith, in each case that relate to the Great Basin Segments (but only if and to the extent any such other agreements provide that they are to be so secured), all as more specifically described and agreed in such Security Documents.

(b) Post-GB Segment COD GB Segment Security Interest. Upon GB Segment COD and if the Final NVE Capacity Entitlement (expressed as a percentage) is greater than thirty-eight percent (38%), unless the Parties agree in writing otherwise in their respective sole discretion, Great Basin shall either (i) increase the GB Segment Security Interest Cap to equal the product of (A) the Final NVE Capacity Entitlement (expressed as a percentage) and (B) the Anticipated Investments for the Great Basin Segments or (ii) if Great Basin has made the Transfer contemplated by Section 15.03(f)(i) or such security interest can be granted under Applicable Law without such transfer and the NVE Parties consent in writing, grant the NVE Parties an increase in the GB Segment Security Interest so that the GB Segment Security Interest shall provide the NVE Parties with a security interest in a percentage of all right, title and interest in, to and under the Great Basin Segments equal to the Final NVE Capacity Entitlement (expressed as a percentage); provided, that if Great Basin has granted the NVE Parties the security interest contemplated by Section 18.04(a)(ii)(A) and subsequently Great Basin has made (or is making as of GB Segment COD) the Transfer contemplated by Section 15.03(f)(i) or the

The NVE Parties’ security interest in Great Basin’s rights in this Agreement related to the Great Basin Segments shall be adjusted to the extent necessary to be consistent with the adjustments contemplated by this Section 18.04(b).

(c) Post-GB Segment COD ON Line Security Interest.

The NVE Parties’ security interest in Great Basin’s rights in this Agreement related to ON Line shall be adjusted to the extent necessary to be consistent with the adjustments contemplated by this Section 18.04(c).

(d) Ownership Adjustment. In the event that the NVE Parties’ Ownership Percentages increase or decrease in accordance with this Agreement, then, after GB Segment COD and upon the written request of a Party, unless the Parties agree in writing otherwise in their respective sole discretion, the NVE Parties shall release a portion of the ON Line Security Interest pursuant to documentation reasonably satisfactory to Great Basin and the ON Line Lenders, or Great Basin shall grant the NVE Parties an increase in the ON Line Security Interest, in either case, so that the ON Line Security Interest shall provide the NVE Parties with (i) either (A) a security interest in all of Great Basin’s right, title and interest in, to and under ON Line, provided that the amount that may be realized with respect to such security interest shall not exceed an amount equal to the product of (1) the positive difference between (x) the Final NVE Capacity Entitlement (expressed as a percentage) minus (y) the NVE Parties’ aggregate Ownership Percentages and (2) the Anticipated Investment in ON Line or (B) if Great Basin has made the Transfer contemplated by Section 15.03(f)(i) or such security interest can be granted under Applicable Law without such transfer and the NVE Parties consent in writing, a

Each of the Parties irrevocably waives, to the fullest extent permitted by Applicable Law, any objection it may now or hereafter have to the jurisdiction of such courts or the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. Each of the Parties hereby consents to service of process by registered mail or receipted courier at its address set forth in Section 20.01 and agrees that its submission to jurisdiction and its consent to service of process by mail are made for the express benefit of the other Parties.

(vi) This Agreement and the rights and obligations of the Parties hereunder shall remain in full force and effect pending the award in any arbitration proceeding hereunder.

(viii) The Parties, to the fullest extent permitted by Applicable Law, hereby irrevocably waive and exclude any recourse to the court system other than to enforce the agreement to arbitrate pursuant to this Section 19.02, for pre-arbitral injunction or pre-arbitral attachment or other order in aid of arbitration proceedings or to prevent irreparable harm prior to the appointment of the arbitral tribunal or enforce the award of the arbitral panel.

(ix) If two or more Disputes arise in connection with this Agreement, then any or all such Disputes may be brought in a single arbitration. If one or more arbitrations are already pending in connection with this Agreement, then any Party to a new Dispute in connection with this Agreement or any subsequently filed arbitration brought in connection with this Agreement may request that such new Dispute or any subsequently filed arbitration be consolidated into any prior pending arbitration. The new Dispute or subsequently filed arbitration shall be so consolidated, provided that the arbitral panel for the arbitration so selected determines that: (A) the new Dispute or subsequently filed arbitration presents significant issues of law or fact common with those in the prior pending arbitration, (B) no Party to the new Dispute or prior pending arbitration would be unduly prejudiced and (C) consolidation under these circumstances would not result in undue delay for the prior pending arbitration. Any such order of consolidation issued by the arbitral tribunal shall be final and binding upon the Parties to the new Dispute, and the prior pending and subsequently filed arbitrations. The Parties waive any right they have to appeal or to seek interpretation, revision or annulment of such order of consolidation under the Rules or in any court. The arbitral tribunal for the prior pending arbitration into which a new Dispute or subsequently filed arbitration is consolidated shall serve as the arbitral tribunal for the consolidated arbitration. The Parties agree that, upon such an order of consolidation, they will promptly discontinue any arbitration brought in connection with this Agreement, the subject of which has been consolidated into another arbitral proceeding in connection with this Agreement.

(x) This Section 19.02(b) shall not apply to the resolution of any Deadlock, audit or allocation Disputes to be resolved by the Independent Auditor or other external auditor or appraiser under Sections 2.02(e) or 2.08, any appraisal to be made under Section 13.05(b), or any Loss Threshold Deadlock to be resolved under Section 13.07 or Section 14.07; provided, however, that Sections 19.02(b)(v) and (viii) shall apply to audit and allocation Disputes to be resolved by the Independent Auditor or other external auditor or appraiser under Sections 2.02(e) and 2.08, any appraisal to be made under Section 13.05(b), and any Loss Threshold Deadlock to be resolved under Section 13.07 or Section 14.07. For the avoidance of doubt, the limitation set forth in this Section 19.02(b)(x) shall not preclude the use of the provisions set forth in Section 19.02(b) for determining a breach of, or interpreting, this Agreement.

Notwithstanding the foregoing sentence, the Books and Records of any Party, any information provided pursuant to Section 9.06 and the terms of this Agreement shall be Confidential Information.

(b) Treatment of Confidential Information. The Receiving Party shall treat any Confidential Information with at least the same degree of care regarding its secrecy and confidentiality as the Receiving Party’s similar information is treated within the Receiving Party’s organization. The Receiving Party shall keep confidential and not disclose the Confidential Information of the Disclosing Party to third Persons, nor use it for any purpose, without the express prior written consent of the Disclosing Party, except the Receiving Party is permitted to disclose Confidential Information without consent as follows:

(i) Disclosure shall be restricted solely to (A) its agents, consultants and representatives as may be necessary to perform its obligations under this Agreement, (B) its Affiliates, shareholders, directors, officers, employees, advisors, NVE Lenders, ON Line Lenders and GB Segment Lenders (as the case may be), rating agencies, and representatives as necessary, (C) any Governmental Authority in connection with seeking any PUCN Approval, FERC Approval or any other required Governmental Approval, (D) as required by Applicable Law or any stock exchange rules or, with respect to any information provided under Section 9.06, financial statements of the NVE Parties if any such information is aggregated with information of other Persons and (E) potential transferees of this Agreement, any Ownership Interests or any ownership interests in the Great Basin Segments (together with their agents, advisors and representatives), as may be necessary in connection with any Transfer (which Transfer shall be in compliance with Article XV) or in furtherance of the resolution of any Dispute pursuant to Article XIX, in each case after advising those Persons of their obligations under this Section 20.08.

(ii) In the event that the Receiving Party is requested or required by Applicable Law to disclose any Confidential Information, the Receiving Party shall provide the Disclosing Party with prompt notice of such request or requirement in order to enable the Disclosing Party to seek an appropriate protective order or other remedy and to consult with the Disclosing Party with respect to the

122

Privileged and Confidential

Execution Version

Disclosing Party taking steps to resist or narrow the scope of such request or legal process. This Section 20.08(b)(ii) shall not apply to the disclosure of this Agreement in connection with any disclosure pursuant to Section 20.08(b)(i)(C) or to comply with any stock exchange rules.

(ii) Information which was available to the Receiving Party on a non-confidential basis prior to its disclosure by the Disclosing Party;

(iii) Information which becomes available to the Receiving Party on a non-confidential basis from a Person other than the Disclosing Party or its representative who is not otherwise bound by a confidentiality agreement with the Disclosing Party or its representative or is otherwise not under any obligation to the Disclosing Party or its representative not to disclose the information to the Receiving Party; and

(iv) Information that is independently developed by the Receiving Party.

(d) Public Statements. The Parties shall consult with each other prior to issuing any public announcement, statement or other disclosure with respect to this Agreement, ON Line or the transactions contemplated hereby and no Party shall issue any such public announcement, statement or other disclosure without having first received Management Committee approval, except as may be required by Applicable Law.

(e) Specific Performance. Each Party acknowledges and agrees that the failure to perform any of its respective obligations under this Section 20.08 would cause irreparable harm to the other Parties and that the remedy at law for any violation or threatened violation thereof would be inadequate, and further agrees that the other Parties shall be entitled to a temporary or permanent injunction, specific performance or other equitable relief specifically to enforce such obligations without the necessity of proving the inadequacy of its legal remedies.

DISCLOSURE SCHEDULE

Reference is made to that certain Transmission Use and Capacity Exchange Agreement dated as of August 20, 2010 between Nevada Power Company, d/b/a NV Energy, Sierra Pacific Power Company, d/b/a NV Energy, and Great Basin Transmission, LLC (the “TUA”). Capitalized terms used herein and not otherwise defined have the meanings specified in the TUA. This Disclosure Schedule constitutes Great Basin’s initial “Disclosure Schedule” for purposes of the TUA:

In connection with Section 17.01(d) of the TUA, it is noted that, in order to consummate the Acquisition Closing, Great Basin will need to obtain (a) the consent of each third party that is party to each ON Line Agreement listed on Schedule 4 attached to the TUA to the assignment of an interest in such ON Line Agreement by Great Basin to NPC, in each case to the extent such consent is required pursuant to the terms and conditions of such ON Line Agreement (such consents being the “Required Consents” for purposes of the TUA), and (b) in connection with each Governmental Approval listed on Schedule 6 attached to the TUA, the consent or approval of each relevant Governmental Authority to (i) the consummation of the Acquisition Closing and (ii) the issuance of such Governmental Approval in the name of the Parties, in each case to the extent the relevant Governmental Authority requires such consent or approval to be obtained.

With respect to each of the ON Line Agreements listed on Schedule 4 that has not been entered into as of the Effective Date, Great Basin’s ability to assign an interest in such ON Line Agreement to NPC as part of the Acquisition Closing may be addressed within such ON Line Agreement, thereby eliminating the need for a separate Required Consent in connection with such ON Line Agreement.

The Parties acknowledge that FERC Approval and PUCN Approval are required as contemplated by Article II of the TUA.

Regarding Section 17.04 of the TUA, one of more Persons has filed for an interconnection request as listed on the Open Access Same-Time Information System (OASIS) of the NVE Parties.
