Exhibit 99.2

EXHIBIT A

CLEANSING MATERIAL

Note: Free cash flow figures derived from the Company’s reserve database which are utilized in the calculation of PV-10 values differ from those used in the Company’s financial forecasts due primarily to the following factors:

• Production volumes – Volumes included in the financial forecasts are lower than those in the reserve database due to the application of downtime assumptions and risking due to potential timing differences.

• Lease operating expenses – Utilizing the methodology prescribed by our third-party reservoir engineering firm, lease operating expenses in the reserve database do not include credits received from non-operating partners for water disposal or liquids gathering fees.

• General and administrative (G&A) expense – The reserve database includes well- level COPAS overhead charges but omits other G&A expenses that are captured in the financial forecasts.

• Capital expenditures – Capitalized G&A expenses and immaterial miscellaneous non-drilling and completion capital are included in the financial forecasts but not in the reserve database.
