OTHER EVENTS. On December 21, 2004, El Paso Natural Gas Company (EPNG) entered into a Precedent Agreement with its largest customer, Southern California Gas Company (SoCalGas). Under the terms of the Precedent Agreement, SoCalGas has agreed to re-contract, effective September 1, 2006, for an annual average of approximately 750 MMcf/d of capacity on EPNG's pipeline system to serve SoCalGas' "core" (residential and small commercial) customers -- which is nearly all the core capacity SoCalGas currently holds on EPNG. Following the satisfaction of specified conditions, the Precedent Agreement provides for the parties to execute new service agreements having a primary term of three to five years at rates that are, on average, less than EPNG's current maximum rates. Such conditions include SoCalGas' receipt of approval from the California Public Utilities Commission (CPUC) and the successful awarding of the capacity to SoCalGas following the post and bid process required by EPNG's tariff. As reported in EPNG's Annual Report on Form 10-K for the year ending December 31, 2003, the main contract between EPNG and SoCalGas, for approximately 1.2 Bcf/d of capacity on EPNG's system, expires in 2006. The remaining capacity from the expiring contracts historically has been used by SoCalGas to serve "non-core" (large commercial, industrial) customers. The CPUC is considering whether the California utilities should be required in the future to hold capacity to serve their non-core customers. EPNG is continuing its efforts to re-contract this capacity directly with such non-core customers, or with other parties, depending on the CPUC's decision. Whether that capacity will be re-contracted by EPNG is unknown at this time. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
