Bonneville and Company are sometimes referred to collectively as "Parties." WITNESSETH: WHEREAS, the Parties entered into a General Transfer Agreement (GTA), Contract No. DE-MS79-88BP92436, dated February 25, 1988 and amended April 11, 1995, which provides, among other matters, for the transfer of electric power and energy to Wells Rural Electric Company (Wells). The Company is currently providing up to 65 MW of transfer service under the GTA. Bonneville delivers this electric power and energy at the Hilltop Point of Replacement (POR); and WHEREAS, the Company has completed construction on a 345 kilovolt (kV) transmission line between the Company's North Valley Road Substation in Reno, Nevada and the Company's Hilltop Substation near Alturas, California (Reno-Alturas Transmission Project); and WHEREAS, the Reno-Alturas Transmission Project is interconnected to Bonneville's Malin-Warner 230 kV Line (Malin-Warner Line); and WHEREAS, Bonneville has by letter dated August 3, 1998 exercised its option to transfer its POR from Midpoint to Hilltop; NOW, THEREFORE, in consideration of the promises and covenants contained herein, the Parties agree to amend the GTA as follows: 1. AMENDMENT TRANSFER SERVICE Exhibit B of the GTA is amended pursuant to the following: "Company shall provide service under the GTA up to a total demand limit of 110 MW, including service delivered pursuant to Contract Number DE-MS79-79BP90000, to include Maggie Creek, Carlin, McNabb, Jiggs Lee, and Winnemucca. Point of Replacement shall be at the Hilltop Point of Interconnection. 2. AMENDMENT TERM Subject to the approval of the Federal Energy Regulatory Commission, this Amendment shall be effective at 2400 hours on the date of execution (Amendment Effective Date). 3. PROVISIONS RELATING TO DELIVERY Section 4(a) of the GTA is amended to read as follows: Page 2 of 4 "(a) Electric power and energy shall be made available by the Company at all times during the term hereof at the points of delivery described in Exhibit B (Points of Delivery), in the amount of Bonneville's Customer requirements at such points and at the approximate voltages specified therein; provided, however, that Bonneville shall make available, pursuant to section 5, electric power and energy at the Points of Replacement specified in Exhibit B; provided, however, that in the event of an outage on the Company's 120 kV transmission system serving the Carlin area and the company is unable to serve both the Company's customer loads and Bonneville's Customer loads, in which case, to the extent possible, interruption of the loads will be shared equitably between the Parties. In no event shall the Company be obligated to import electric power and energy hereunder at a demand level in excess of the import demand limit specified in Exhibit B, except where otherwise agreed. If any of Bonneville's Customer load is interrupted, the Company may provide service pursuant to section 6 of the GTA. In the event insufficient import capability to the Company's system exists, Bonneville shall provide power in excess of the demand limit from inside the Company's import boundary in a manner specified by the Company, or reduce deliveries accordingly. The Company will give priority to residential customers and other critical loads in its use of Valmy Generation." 4. PAYMENT FOR TRANSFER OF POWER Section 9(a) of the GTA is amended to read as follows: "(a) For the use of Company services and facilities in transferring electric power and energy hereunder, Bonneville shall pay the Company each month in the term hereof an amount equal to the sum for all Points of Delivery of the greater of (1), (2) or (3) below for each point of delivery; provided however, that certain Points of Delivery shall be coincidentally combined as specified in Exhibit B". Section 9(a)(3) of the GTA is amended to read as follows: "(3) The product of [1] the Transmission Reservation shown in Exhibit G for the current month and [2] the Transfer Charge." 5. STATUS OF AMENDMENT It is expressly understood and agreed by the Parties that all the terms, conditions, and provisions of this Amendment are made part of the GTA upon the Amendment Effective Date as though the GTA were expressly rewritten to incorporate and include the contents of this Amendment.
