In the event that such Dispute is not resolved by the Executive Committee within thirty (30) days after service of the Dispute Notice, either Party may refer the Dispute to binding arbitration for final resolution under Section 9.2(b) (“Arbitration Notice”).

(b) Binding Arbitration. (i) Subject to Section 9.2(a), upon mutual agreement of the Parties, for a Dispute involving technical or operational issues, the Dispute shall be adjudicated exclusively by a single Arbitrator, who shall be designated by mutual agreement within five (5) days after the Arbitration Notice is served. If the Parties are unable to agree on an Arbitrator

within five (5) business days after the Arbitration Notice is served, either Party may make a written request to the then-Chair of the RCA to select an Arbitrator for the Parties, which selection shall be final. (ii) For all disputes not resolved under Section 9.2(b)(i), the Dispute shall be adjudicated exclusively by binding arbitration administered by the AAA under its Commercial Arbitration Rules. There shall be three Arbitrators (“Panel”). The Parties agree that one Arbitrator shall be appointed by each Party within twenty (20) days of Arbitration Notice is served, or, in default thereof, appointed by the AAA in accordance with its Commercial Rules, and the third presiding Arbitrator shall be appointed by agreement of the two Party-appointed Arbitrators within fourteen (14) days of the appointment of the second Arbitrator or, in default of such agreement, by the AAA. (iii) The decision rendered by the Arbitrator or Panel shall be final, non-reviewable, non-appealable and binding on the Parties and may be enforced in any court having jurisdiction. In emergency situations, the Parties also agree that interim relief may be awarded by the Arbitrator in his best discretion or by the Panel utilizing the AAA Optional Rules for Emergency Measures of Protection and that such interim relief can be requested by either Party at any time following service of the Arbitration Notice but prior to issuance of a final decision by the Arbitrator or the Panel as the case may be.

Section 9.3 Continued Performance. While the procedures in this Article 9 are pending, each Party (including, for the avoidance of doubt, any disputing Party) shall continue to perform its obligations under this Agreement in the manner in which they were performed prior to the dispute, unless doing so would be impossible or impracticable under the circumstances.

Article 10 FORCE MAJEURE

Section 10.1 No Breach of Agreement for Force Majeure Events. No Party shall be considered to be in breach of this Agreement to the extent that a failure to perform its obligations under this Agreement is due to a Force Majeure Event. A Party rendered unable to fulfill any of its obligations by reason of a Force Majeure Event shall give prompt notice thereof and shall exercise due diligence to remove such inability within a reasonable time period. If oral notice is provided, it shall be promptly followed by written notice. If the Force Majeure Event results in the loss of generation, then any generation replacement will be considered in as outlined in Section 4.3.

Section 10.2 Limitations on Force Majeure Events. No Party shall be relieved of liability for breach or other failure of performance hereunder to the extent that such failure is due to causes arising out of its own negligence or due to removable or remediable causes that it fails to remove or remedy within a reasonable time period. Nothing contained herein shall be construed to require a Party to settle any strike or labor dispute in which it may be involved. No Party shall be relieved by operation of this Article of any liability to make payments described herein or determined hereunder (including pursuant to the Settlement Process) when due or which the Party is obligated to make with respect to performance which occurred prior to the occurrence of the Force Majeure Event.

EXHIBIT E

SETTLEMENT PROCESS

Upon the completion of the Implementation Period, unless otherwise stated, the processes set forth in this Exhibit E shall both govern and determine the purchases, sales, and prices of all Transactions between and among the Parties. The Parties’ existing economy energy tariffs shall be used for pricing energy during the Implementation Period. Unless otherwise agreed to by the Parties, the Delivery Point of transfers of Energy and other applicable Ancillary Services between the Parties shall be deemed to occur at a Delivery Point listed in Exhibit G. Such Energy transfers and other applicable Ancillary Services shall be made without the imposition of transmission wheeling charges within seven (7) days of the Execution Date of this Agreement. The Parties will develop new provisions governing ancillary services as necessary during the Implementation Period.

Section 1 General

The following shall apply to the settlement of all Transactions between and among the Parties hereunder:

(a)All quantities of Energy Services to be bought and sold shall be determined and be binding obligations of the Parties according to the Day-Ahead Schedule or the applicable Re-Schedule performed pursuant to Section 6.1.

(b)All compensation for the quantities of Energy Services bought and sold shall, consistent with Section 2 of this Exhibit E, be determined according to the actual availability of each Party’s Generation Resources, actual output of Variable Generation Resources, and actual Native load.

(c)For each hour, a Party owning Generation Resources and existing contractual purchases or new purchases from Qualifying Facilities that in aggregate are scheduled to produce less Energy than that Party’s Native Load is an “Energy Buyer”.

(d)If in an hour there is an Energy Buyer, then a Party with Generation Resources that in aggregate produce more Energy than that Party’s Native Load is an “Energy Seller”.

(e)A Party that produces, or has rights to, more than its requirements of Spin, Regulation Up or Regulation Down may be a Seller of that Energy Service. A Party that produces less Spin, Regulation Up or Regulation Down than necessary to satisfy its Reliability Obligations is a buyer of that Energy Service.

(f)The Least Cost Energy scheduled to be produced by a Party’s available Generation Resources on the Actual Dispatch Day shall be dedicated first to meet that Party’s Native Load. The Least Cost Spin, Least Cost Regulation Up and

E-1

Least Cost Regulation Down carried on a Party’s available Generation Resources shall be dedicated first to meet that Party’s Reliability Obligations.

(g)The Least Cost Energy Dispatched from a Party’s Generation Resources in excess of its Native Load shall be sold first to Parties as Energy Buyers up to the level

(h)needed to satisfy the Parties’ aggregate Native Loads. Remaining available Least Cost Energy may be sold to non-party Economy Energy buyers.

(i)Any Energy production that effectuates a non-party Economy Energy buyer or seller Transaction shall have no negative effect on the economic interest of any Party measured hourly.

(j)The Parties shall initially operate as separate load balancing areas during the Implementation Period and each Party shall provide its own Regulation Up and Regulation Down, unless Regulation Up and Regulation Down can be provided while operating as separate load balancing areas. The Parties may operate as a single load balancing Area if approved by the Executive Committee. The Parties intend to achieve a single load balancing area during the Implementation Period. At such time that a single load balancing area is formed Economy Energy and/or Energy Service Transactions may be settled on actual rather than scheduled Energy, consistent with the terms associated with single load balancing area formation. The Executive Committee shall determine the balancing authority entity during the Implementation Period.

(k)The Operating Committee shall develop, modify and approve all elements used to compute Transaction prices. Elements include but are not limited to Generation Resource Data.

(l)Energy Buyers shall be responsible for supplying the Fuel and their respective Fuel Costs.

Section 2 Energy Services Settlement Process

For each hour of the Actual Dispatch Day, compensation for the Energy Service Transactions between the Parties, as defined according to Exhibit E, Section 1, shall be determined as follows:

(a)Each Party shall make payments associated with its own “Pool Savings”. Pool Savings and associated payments shall be determined as follows.

i.The Party’s Cost Responsibility is determined by the actual dispatch of the day being settled.

ii.The Cost Responsibility as determined through the calculation of the SSCED minus the Cost Responsibility determined through the actual operation of the SCED shall be a Party’s preliminary “Pool Savings”. If a Party’s preliminary Pool Savings are negative, then see Appendix –

E-1

Settlement Process Examples, E-1, “Party’s Preliminary Pool Savings are Negative”.

iii.Spin shall be priced during the Implementation Period in a manner consistent with the Parties’ current pricing practices, but in no case less than the full incremental cost of supply.

iv.Pricing for regulation will be developed during the Implementation Period, and in no case less than the full incremental cost of supply.

v.Final Pool Savings is determined by the combination of Exhibit E, Section 2(a)(ii) and Exhibit E, Section 2(a)(iii).

vi.For each hour of the Actual Dispatch Day the Energy Buyer shall pay the Energy Seller, in aggregate, one-half of its final Pool Savings.

vii.For each hour of the Actual Dispatch Day the Energy Seller shall pay the Energy Buyer, in aggregate, one-half of its final Pool Savings.

(b)In light of Chugach's and MEA's joint ownership of the multiple interconnected Delivery Points shown in Exhibit G and the fact that wheeling charges negatively impact the benefits to each Party, the Parties agree that for all Pool Transactions between Chugach and MEA to meet Native Load requirements there will be no cost of wheeling. The respective obligations of the Parties in regard to assessing no wheeling charges for energy transfers between the Parties at the Delivery Points identified in Exhibit G shall become effective within seven (7) days of the Execution Date and survive the termination of this Agreement for any reason. Wheeling costs applicable to additional participants, contracts or amendments that may be added to this Agreement shall be determined and agreed to by the Parties on a case-by-case basis.

E-1

EXHIBIT F

ECONOMY ENERGY TRANSACTION PROCESS

The processes set forth in this Exhibit F shall both govern and determine the rights and prices of all Transactions between and among the Parties to non-party Economy Energy buyers and Economy Energy sellers.

Section 1General

The following shall apply to all Energy and Spin Transactions between and among the Parties to Economy Energy buyers and Economy Energy sellers hereunder:

(a) The Central Scheduling Service, as part of the Day-Ahead Schedule, may purchase non-firm power from non-Parties when such purchase reduces overall costs to the Parties. The costs and benefits of such transactions shall be allocated to the Party whom had the highest variable cost of operation for the period of the transaction

(b) The Energy Seller (Party) shall have rights over an Energy Buyer’s (Party) Generations Resource capacity up to the amount of Energy the Energy Seller provides to an Energy Buyer required to meet their Native Load as determined by the Security Constrained Economic Dispatch. If this Generation Resource is dispatched to make Economy Energy sales, then the Energy Seller shall have the right to produce Economy Energy from an Energy Buyers Generation Resources up to the amount of Energy the Energy Seller sells to that Energy Buyer to meet Native Load as determined by the Security Constrained Economic Dispatch. These rights remain until such a time as the Economy Energy buyer indicates that they are not able to agree to a transaction with the Energy Seller.

(c) The Energy Seller (Party) shall provide the fuel required to produce the Economy Energy, the cost of fuel transportation incurred by the owner of the Generation Resource and the Variable O&M Cost for the Generation Resource used to produce the Economy Energy. Any margin negotiated shall be between the Energy Seller (Party) and Economy Energy buyer (non-party) per their respective economy energy tariffs. For clarity, the Energy Seller (Party) negotiates the Economy Energy Transaction with the Economy Energy buyer.

(d) Energy Sellers or Economy Energy buyers that make Economy Energy Transactions shall be responsible for providing and arranging for delivery of fuel to the Generation Resources that produce the Economy Energy. Energy Sellers that make Economy Energy sales shall be responsible for compensating Generation Resource owners for Variable O&M Costs incurred to produce Economy Energy.

F-1

(e) Spin Back provided by an Economy Energy buyer may be used by the Economy Energy Seller to minimize Production Costs.

(f) Parties that make Economy Energy sales are responsible for all accounting and billing of Economy Energy. This includes but is not limited to fuel supply and transportation cost, Generation Resource Variable O&M Costs and margins.

(g) Owners of Generation Resources (Parties) that produce Economy Energy for other Parties are responsible for all accounting and billing of O&M costs associated with Economy Energy production.

EXHIBIT H

NEW FIRM WHOLESALE POWER CONTRACTS PROCESS

The processes set forth in this Exhibit H shall govern and determine the rights of each Party under the Agreement with respect to any Firm Wholesale Power Contracts negotiated between the Parties and non-party buyers.

All Generation Resource capacity not otherwise committed to meeting the Native Load of the Parties, including that of Section 1(b) of Exhibit F, will be available to the Party entering into a new Firm Wholesale Power Contract to provide the Energy Services required by the new Firm Wholesale Power Contract.

A Party negotiating with a non-Party buyer for a Firm Wholesale Power Contract to serve a load outside of that Party’s certified service territory shall provide written notice of such negotiations to the other Party prior to the execution of any such Firm Wholesale Power Contract.

The Parties shall meet and confer regarding the impact of such new Firm Wholesale Power Contracts. If a Party determines the proposed Firm Wholesale Power Contract impairs the economic benefit that Party receives under this Agreement, then the Party pursuing the Firm Wholesale Power Contract may elect to either ensure the Parties to this Agreement are not harmed despite the new Firm Wholesale Power Contract or terminate this Agreement if Material Financial Regret will occur. Any such termination notice will provide two-years advance notice.

The Party selling Energy Services to a non-party buyer shall (1) provide the fuel required to produce such Energy Services, (2) pay the cost of fuel transportation incurred by the owner of the Generation Resource, and (3) pay the Variable O&M Cost for the Generation Resource used to produce the Energy Services.

APPENDIX 1 – SETTLEMENT PROCESS EXAMPLES

Example E-1 – Party’s Preliminary Pool Savings are Negative

When the cost of a Party's SSCED is less than the Party's native load portion of the SCED, the Parties will split costs and savings consistent with Spilt the saving Principles. An example where this could occur is as follows:

A Party’s SSCED minus SCED is equal to a Party’s preliminary pool savings.

Party A's preliminary pool savings is $1000.

Party B's preliminary pool savings is -$400.

Parties A will make a payment totaling $500 to Party B.

Party A will be billed an additional $200 from Party B.

The result is each Party will net a savings from pool operation of $300
