NOW, THEREFORE, in consideration of the mutual covenants herein contained and other good and valuable consideration, the sufficiency and adequacy of which are hereby acknowledged, the Parties agree to the following:

1.1Each Party shall perform its respective responsibilities as set forth in this Contract in good faith and shall use reasonable efforts to complete those responsibilities on a timely basis. With regard to all dates and time periods set forth in this Contract (other than Section 1.2), time is of the essence.

2.1    Subject to satisfaction of the conditions precedent described in Section 4, or the waiver of such conditions precedent exercised by the applicable Party or Parties, effective at the beginning of the day, as of 12:00:00 a.m. Mountain Prevailing Time, on May 1, 2024 (the “Withdrawal Time”), the following will simultaneously occur unless otherwise agreed to by the Parties in writing:

2.1.1    NRPPD’s withdrawal from its membership in Tri-State will become effective pursuant to Rate Schedule No. 281;

2.1.2    Except as otherwise provided herein, the contracts identified in Schedule 2.1.2 (including, for avoidance of doubt, the WESC) will terminate and be of no further force and effect; provided that any provisions in the contracts that survive termination pursuant to the terms of such contracts shall survive;

2.1.3    As NRPPD has elected to take the discounted value of its patronage capital in a discounted lump sum credit as set out in Rate Schedule No. 281, Tri-State will retire, and NRPPD will relinquish its right to, any patronage capital retirement or allocation arising from NRPPD’s membership in Tri-State or Tri-State’s furnishing of wholesale electric service to NRPPD, including any patronage capital arising under Article VII, Section 3 of Tri-State’s Bylaws, and any property rights it may have in the event of dissolution arising under Article II, Section 1 of Tri-State’s Bylaws or otherwise. No patronage capital will be allocated to NRPPD or retired to NRPPD or paid in cash to NRPPD at any time after the Withdrawal Time. Notwithstanding the foregoing, should Tri-State’s Board of Directors declare any patronage capital retirements prior to the Withdrawal Time, NRPPD shall receive its proportionate share of such payment(s), and Tri-State shall not modify the date or manner of such payment(s) so as to exclude NRPPD from such payment(s); and

The payment of the Final Payment Amount shall be made by wire transfer of immediately available funds to an account designated by Tri-State. NRPPD’s payment to Tri-State for the Equipment Conveyed is included in the Final Payment Amount. In the event the FERC-accepted and effective version of Rate Schedule No. 281 as of April 24, 2024 is the version Tri-State filed on September 1, 2021, Sections 1.3, 2.1.4, 3.1.1, and 5.2 are not applicable and the conveyance of the Equipment Conveyed is excluded and any true-up of the Final Payment Amount will be in accordance with Section 3.2.

3.1.1    Final Payment Amount. At least 30 days before the Withdrawal Time, Tri-State shall calculate and provide to NRPPD the Final Payment Amount, which shall use the formula set forth in Rate Schedule No. 281.

3.2    True-Up.

5.1.1    Until the Withdrawal Time, NRPPD will continue to purchase from Tri-State, and pay Tri-State for, all electric service, including capacity and energy, which NRPPD shall require for the operation of its system at Tri-State’s Class A member rate, in accordance with and subject to the terms of the WESC (and other related agreements currently in effect).

5.1.2    Notwithstanding any other provisions of this Contract, NRPPD shall continue to remain responsible for and shall pay Tri-State, in accordance with the payment provisions of the WESC, for any unpaid bills related to electric service, including, but not limited to, the bill for electric service for the last month of service, and for any other unpaid bills or work whether arising under the WESC or other applicable contracts (including the contracts identified in Schedule 2.1.2) incurred prior to the Withdrawal Time.

between Tri-State and U.S. Bank Trust Company, National Association, as it may be amended or supplemented from time to time.

5.2.2    Upon reasonable advance notice from NRPPD to Tri-State, Tri-State will give NRPPD and its representatives reasonable access during normal business hours to review, copy and inspect the books, records, drawings, documents, and instruments relating to the Equipment Conveyed. NRPPD, at its own cost and expense, shall have the right to inspect and test the Equipment Conveyed for condition and for conformance with applicable legal requirements and Tri-State, at Tri-State’s cost and expense, shall cooperate in facilitating access in this regard. NRPPD will comply with all conditions and requirements communicated by Tri-State, as well as with all Federal, state and local laws, in connection with such access and inspections. NRPPD will promptly reimburse Tri-State for the actual costs associated with Tri-State repairing any damage or disturbance NRPPD causes to the Equipment Conveyed, or to land upon which the Equipment Conveyed is situated, and will otherwise restore such Equipment Conveyed and land after each such inspection, examination, evaluation, or other access.

5.2.3    Tri-State shall pay all fees, costs, and taxes attributable to the Equipment Conveyed arising, accrued, or incurred prior to Withdrawal Time; provided, however, that such fees, costs, and taxes may be prorated to the date of Withdrawal Time for each particular item of Equipment Conveyed, and such obligation shall survive. Further, state or local sales, use, transfer, or fees or any other charge imposed by any governmental authority (other than any of Tri-State’s income or payroll tax) arising from or payable by reason of the transfer of the Equipment Conveyed contemplated by this Contract will be borne by NRPPD. Tax returns required to be filed in respect of such transfer taxes (“Transfer Tax Returns”) will be prepared and filed by the Party that has the primary responsibility under applicable law for filing such Transfer Tax Returns. If neither Party has primary responsibility for filing a Transfer Tax Return, then NRPPD will be responsible for preparing and filing any such Transfer Tax Return. The Parties will cooperate, including during times of audit by taxing governmental authorities, to avoid payment of duplicate or inappropriate taxes which relate to the Equipment Conveyed, and each Party will furnish, at the request of the other, proof of payment of any such taxes to avoid payment of a duplicate or inappropriate tax.

5.2.4    At or prior to the Withdrawal Time, Tri-State shall deliver to NRPPD a Bill of Sale substantially in the form of Exhibit B for transferring the Equipment Conveyed.

5.3    Transmission Service. NRPPD shall have the sole obligation to apply for and obtain transmission service commencing on the Withdrawal Time and Tri-State shall have no liability to NRPPD for its failure to apply for or obtain such transmission service.

5.4    Metering Coordination.

5.5    FERC Acceptance or Approvals. Tri-State shall, at its expense, seek and obtain FERC approval or acceptance of the termination of the WESC and other jurisdictional agreements identified in Schedule 2.1.2. Tri-State shall share with NRPPD drafts of such filings prior to filing sufficiently in advance of filing so that NRPPD has reasonable opportunity to comment on such filing. If Tri-Sate has shared such drafts with NRPPD and incorporate any NRPPD’s edits to such filing, NRPPD shall, at its expense, use commercially reasonable efforts to support Tri-States efforts to obtain FERC’s acceptance or approval of termination of the contracts (including the WESC). However, if FERC does not approve or accept for filing any such filing related to any agreements identified in Schedule 2.1.2, to the extent they are required to be filed, without condition or modification (unless such condition or modification is mutually agreeable to the Parties as evidenced by their written agreement), the Parties agree to work together in good faith to agree upon terms and conditions that are acceptable to them and to FERC and Tri-State agrees to promptly file such new terms and conditions with FERC for approval, acceptance or termination, as appropriate.

5.6.2    To the extent Tri-State’s Class A member rate becomes subject to a true up that covers the period prior to the Withdrawal Time, for any energy, power or services NRPPD purchased from Tri-State during the refund period (but not later than the Withdrawal Time), Tri-State shall be entitled to collect, and NRPPD shall be required to pay, such true up amount, subject to the effective rate on file with FERC; provided however, that in lieu of such true up being added to the Class A rate or a line item on the invoice for the wholesale electric services contract, NRPPD shall pay such amount directly to Tri-State within 30 days of receipt of an invoice from Tri-State.
