Amendment Description	Explanatory Note We are amending and restating in their entirety the following items of our Quarterly Report on Form 10-Q for the period ended September 30, 2015 as originally filed with the Securities and Exchange Commission on October 30, 2015 (our “Original Report”): (i) Item 1 of Part I “Financial Statements,” (ii) Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” (iii) Item 4 of Part I, “Controls and Procedures,” and (iv) Item 6 of Part II, “Exhibits,” after identifying certain non-cash errors in such financial statements caused by the fact that the estimate of our proved oil and natural gas reserves as of September 30, 2015 overstated the net proved reserves, with the error in such report occurring as the result of all applicable costs not being considered when preparing the operating cost estimate for the reserve report. The adjustments are more fully described in Note 1 to the restated condensed consolidated financial statements presented in this Form 10-Q/A. We have also updated the signature page and the certifications of our Chief Executive Officer and Chief Financial Officer in Exhibits 31.1, 31.2 and 32.1. No other sections of our Original Report are affected by this amendment. For the convenience of the reader, we are re-filing the Original Report in its entirety in this Form 10-Q/A. This Form 10-Q/A continues to speak as of the date of the Original Report and other than with respect to the restatement of the Company’s financial statements and other financial information as described above does not reflect events occurring after the filing of the Original Report. The financial and other information contained in the Original Report should no longer be relied upon.
