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

3.01Ownership 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

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.

3.02Electrical 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

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.

 (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

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).

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.

10.05Transfer 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.

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

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.

12.03Waiver 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

13.04Payment 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

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.

13.05Rebuild 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

(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.

13.06Great 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.

13.07Event 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.

15.01Transfers.

(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.

15.02Right 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

90

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

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.

15.03Permitted 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”):

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 Defaulthas 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.

 (C)“Outstanding Payments” means the aggregate

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.

16.03Additional 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.

16.04Interest 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.

16.05Mitigation.  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.

19.02Dispute Resolution; Binding Arbitration.

(a)Negotiation.  Any dispute or claim arising under or relating to this Agreement, or the breach, termination or validity hereof (a “Dispute”), which cannot be resolved by the Parties through negotiation by the Parties’ Authorized Representatives within ten (10) days after receipt by a Party of written referral thereto by any other Party (a “Notice”) shall be referred to a panel consisting of a senior executive (President or a Vice President) of each Party, with authority to decide or resolve the Dispute, for review and resolution.  Such senior executives shall meet and attempt in good faith to resolve the Dispute within twenty-five (25) days after receipt of a Notice.  If, for any reason, a Dispute has not been resolved within forty-five (45) days after receipt of the Notice, then any Party may refer such Dispute to arbitration for final resolution in accordance with Section 19.02(b).

(b)Arbitration.

 (i)At the request of any Party following the expiration of the period for senior executives to seek to resolve a Dispute set forth in Section 19.02(a), upon written notice to that effect to the other Parties (a “Demand”), the Dispute shall be finally settled by binding arbitration before a panel of three (3) arbitrators in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”) then in effect (the “Rules”), except as modified herein and unless the Parties agree otherwise in writing; provided, however, that any Dispute regarding Contributions or other payments required hereunder shall be resolved on an expedited basis (regardless of the amount in Dispute) by a single arbitrator (but such single arbitrator is still referred to in this Section 19.02(b) as the “arbitral panel”) in accordance with the expedited procedures provided for by the Rules.  The Demand must include statements of the facts and circumstances surrounding the Dispute, the legal obligation breached, the amount in controversy and the requested relief accompanied by documents supporting the Demand.

 (ii)The arbitration shall be held and the award shall be issued in LasVegas, Nevada.  The arbitration shall be governed by the United States Arbitration Act, 9 U.S.C. §§ 1 et seq.

 (iii)If there is a single arbitrator, the Parties shall have fifteen (15) days from receipt by a Party of a Demand to agree on the single arbitrator.  If there are three (3) arbitrators, the NVE Parties collectively shall select one (1) arbitrator and Great Basin shall select one (1) arbitrator, in each case within fifteen (15) days after the receipt of the Demand.  Within fifteen (15) days after the selection of the second arbitrator, the two (2) arbitrators thus appointed shall select the third arbitrator, who shall act as the chairman of the panel.  If any arbitrator is not timely appointed, the AAA shall make such appointment in accordance with the listing, ranking and striking procedures in the Rules, with each of the NVE Parties and Great Basin having a limited number of strikes (to be agreed by the Parties or, failing such agreement, determined by the AAA) except for cause.

 (iv)The award shall be in writing (stating the award and the reasons, findings of fact and conclusions of law on which it is based), shall be final and binding upon the Parties and shall be the sole and exclusive remedy among the Parties regarding any Disputes, counterclaims, or accountings presented to the arbitral panel.  The arbitral panel shall be authorized in its discretion to grant pre-award and post-award interest at commercial rates, except to the extent that applicable interest rates are otherwise provided herein.  Judgment upon any award may be entered in any court having jurisdiction.

 (v)For purposes of a pre-arbitral injunction, pre-arbitral attachment or other order in aid of arbitration proceedings, the Parties hereby agree to submit to the exclusive jurisdiction of the federal courts of the United States located in Las Vegas, Nevada, and the courts of the State of Nevada located in Las Vegas, Nevada (collectively, the “Las Vegas Courts”) and to the non-exclusive jurisdiction of the Las Vegas Courts for the enforcement of any arbitral award rendered hereunder.  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.

 (vii)Each Party shall bear its own costs and fees, including attorneys’ fees and expenses.  The Parties expressly agree that the arbitrators shall have no power to consider or award any form of damages barred by Section 12.03.

 (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.

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.
