ATP OIL & GAS CORPORATION AND SUBSIDIARIES
We originally filed our Form 10-K for the year ended December 31, 2009 on March 16, 2010 (the 2009 Form 10-K). We are filing this Amendment No. 1 to the 2009 Form 10-K (this Amendment) solely for the purpose of filing revised reports of our third-party petroleum engineering firms and to provide updated consents of our third-party petroleum engineering firms. The report of Collarini Associates was filed as Exhibit 23.5 to the 2009 Form 10-K. The report did not contain certain information contemplated by Item 1202(a)(8)(iv), (v) and (viii) of Regulation S-K. The report of Collarini Associates appearing in this Form 10-K/A includes such information. The reports of Ryder Scott Company, L.P. were filed as Exhibits 23.6 and 23.7 to the 2009 Form 10-K. The reports included a statement limiting the use of the report to ATP Oil & Gas Corporation. The reports of Ryder Scott Company, L.P. appearing in this Form 10-K/A reflect the removal of any such limitation.
