Item 8.01. Other Events.

Western Gas Resources, Inc. (“Western” or the “Company”) has previously announced that it intends to file its Quarterly Report on Form 10-Q for the period ended September 30, 2005, as soon as practicable. Western had previously received waivers from its lenders under its revolving credit facility and master shelf agreement to extend the delivery date of its unaudited financial statements and related compliance certificate for the third quarter of 2005 to December 14, 2005.

On December 14, 2005, Western received a further 30-day waiver from its lenders under its master shelf agreement, to extend the date of delivery of its unaudited financial statements and related compliance certificate for the third quarter of 2005 to January 14, 2006. In addition, under the Company’s revolving credit facility, amended and restated on November 22, 2005, the unaudited financial statements and related compliance certificate for the third quarter of 2005 are not due until January 21, 2006. The Company does not expect that it will need the full duration of these extensions as it anticipates filing its Quarterly Report on Form 10-Q for the period ended September 30, 2005 shortly.
