NYMEX Provides Update on Natural Gas Force Majeure Declaration

Tue Sep 27 2005

NEW YORK, N.Y., September 27, 2005 — The New York Mercantile Exchange, Inc., announced today that its prior declaration of force majeure relating to all remaining delivery obligations in the September 2005 NYMEX Division natural gas futures contract will continue in effect. In addition, the Exchange has determined to declare force majeure for the October 2005 natural gas contract.

NYMEX's force majeure declaration for delivery obligations in these contract months was made in the context of the continuing force majeure declaration by Sabine Pipeline LLC, the operator of the Henry Hub facility in Louisiana At this time, the Exchange anticipates a lifting of the force majeure declaration at the Henry Hub facility in October 2005. With regard to such a lifting NYMEX presently plans to extend the delivery period for the September 2005 contract for an appropriate amount of time pursuant to NYMEX rules.

As to the October 2005 natural gas futures contract, which expires tomorrow, termination and settlement will be performed as per standard procedures. Any party that ultimately maintains a delivery position in the October 2005 contract through termination will be required to nominate volumes and complete its obligations within the month of October commencing immediately with the lifting of the force majeure condition by Sabine.

However, the Exchange reserves the right under its rules to revisit the timing of delivery depending principally upon the actual timing during October of termination of Sabine's and NYMEX's force majeure declarations.

All parties have available now, as always, the ability to mutually agree to execute an alternative delivery procedure pursuant to NYMEX rule 220.17(A) for the September 2005 delivery obligations.
