DBRS has today released a report on ConocoPhillips (COP or the Company) that provides further detail on the confirmation of the Company’s ratings on February 22, 2012.

DBRS confirmed the Unsecured Long-Term Notes & Debentures of COP and the Senior Unsecured Notes and Debentures of Burlington Resources Inc. at ‘A’ with Stable trends. This removed the ratings from Under Review with Developing Implications, where they were placed on July 14, 2011, following COP’s announcement of a proposal to separate its refining and marketing and exploration and production businesses into two, pure-play, stand-alone, highly focused, publicly traded corporations. DBRS also confirmed the Commercial Paper rating of COP at R-1 (low) with a Stable trend.

Today’s report and the February 22, 2012, press release are available at www.dbrs.com or by
