8.01   Other Events.

     On October 10, 2004, a decision was handed down by the U.S. District Court of the Southern District of New York in the appeal by Nevada Power Company (“NPC”) and Sierra Pacific Power Company (“SPPC”) from the judgment (the “Judgment”) entered by the Bankruptcy Court for the Southern District of New York against NPC and SPPC in favor of Enron Power Marketing, Inc. (“Enron”), for damages based on Enron’s claim for breach of its power supply agreements with NPC and SPPC. The U.S. District Court’s decision vacates the Judgment and remands the matter to the Bankruptcy Court for fact-finding on several issues including:

• whether Enron’s demand for collateral at the time of termination of its power supply contracts with NPC and SPPC was reasonable;

• were the assurances offered by NPC and SPPC “reasonably satisfactory”; and

• whether Enron would have been able to perform under the power supply contracts at the time the contracts were terminated.

     The District Court further held that the demand for assurances by Enron should have been limited to the amount of its actual loss and rejected Enron’s cross-appeal seeking a 12% per year post-judgment interest rate instead of the 1.21% interest rate ordered by the Bankruptcy Court. The District Court decision also provides that Enron may renew its motion to enjoin the proceedings currently before the Federal Energy Regulatory Commission addressing Enron’s termination of its power supply contracts with NPC and SPPC.

     Pursuant to a stipulation and agreement previously entered into among NPC, SPPC and Enron, the collateral contained in NPC’s and SPPC’s escrow accounts that secured their stay of execution of the Judgment will remain in place through the pendancy of all remands and appeals.

     A copy of the District Court’s decision is attached as exhibit 99.1 hereto.
