During 2008 we produced 10.5 MMBoe and sold approximately 11.6 MMBoe of proved reserves. Net of production and property sales, reserves decreased by 5 MMBoe (3%) on a proved basis and 29 MMBoe (11%) on a proved plus probable basis. We drilled a total of 192 net wells during 2008, four of which were classified as exploratory wells, as compared to 266 net wells in 2007 of which 25 were exploratory. Our 2008 drilling program focused primarily on development activities and the advancement of reserves from the proved undeveloped and probable categories to the proved producing classification in contrast to the greater emphasis placed on discoveries and extensions in prior years. As a result, our proved developed producing reserves increased by approximately 6 MMBoe or 7.3% before production and property sales.

Technical revisions reflect adjustments to reserve estimates made in previous years and relate to expected future well performance based upon additional production history, the impact of current operating factors on sales volumes including fuel gas usage associated with production facilities, and land expiries. Aggregate negative technical revisions, related to December 31, 2007 reserve bookings, were 18.3 MMBoe on a proved basis and 41.7 MMBoe on a proved and probable basis. In the Niton and Hooker areas, a small number of wells accounted for the majority of well performance related revisions. Niton accounted for 4% of the proved revisions and 11% of the proved and probable revisions. Approximately 75% of the proved revisions at Niton are attributable to two horizontal wells. A total of 189 wells are on production at Niton including 26 horizontal wells. The Hooker area contributed 25% of proved and 21% of proved and probable negative revisions. Approximately 60% of the proved revisions relate to 14 Basal Quartz wells, including three undeveloped locations; in total, 102 Basal Quartz wells are on production in the area. The Plains Belly River accounted for approximately one-half of the negative well performance related revisions. The technical revisions result from a general reduction in the ultimate recovery from 63% of producing well locations. This reduction was also applied to the proved undeveloped and probable locations. Approximately 15% of proved plus probable revisions relate to operational factors and land expiries. Finding and Development Costs ----------------------------- Finding and Development (F&D) and Finding, Development and Acquisition (FD&A) costs are used as a measure of capital efficiency and are determined by dividing the capital costs for the period, including the change in estimated future development capital, by associated reserve additions. During 2008, we incurred total capital expenditures of $324 million, excluding acquisitions and proceeds from dispositions. These expenditures added 14,649 MBoe to proved reserves and 13,719 MBoe to proved plus probable reserves, which resulted from discoveries, extensions, and improved recoveries. Future capital associated with placing proved reserves on production is estimated to be $289 million and future capital associated with placing proved and probable reserves on production is $1,045 million. This reflects a reduction from 2007 of future capital associated with proven and proven plus probable reserves of $30 million and $120 million respectively. Reductions of future capital reflect, in part, our 2008 focus on the promotion of reserves to the producing category. F&D costs for 2008 do not reflect technical revisions as these revisions relate to preceding years. Three year average F&D costs include technical revisions. FD&A costs, which include reserves and capital associated with acquisitions, is also presented. During 2008, Compton acquired 473 MBoe of proven plus probable reserves at a total cost of $11 million and disposed of 11,325 MBoe of proven plus probable reserves for proceeds of $203 million. In all cases, capital expenditures are before proceeds on the disposition of reserves during the period. ------------------------------------------------------------------------- 2008 3-Year Average ------------------------------------------------------------------------- Excluding Including Excluding Including (Including change Technical Technical Technical Technical in future capital) Revisions Revisions Revisions Revisions ------------------------------------------------------------------------- F&D Costs ($/boe) ------------------------------------------------------------------------- Total Proved $ 20.14 n.a $ 28.58 $ 28.07 Total Proved + Probable $ 14.91 n.a $ 14.67 $ 28.85 ------------------------------------------------------------------------- FD&A Costs ($/boe) ------------------------------------------------------------------------- Proved $ 20.29 n.a $ 26.70 $ 26.33 Proved + Probable $ 17.27 n.a $ 12.86 $ 21.04 ------------------------------------------------------------------------- Year-end financial reports are in the process of being completed. The capital expenditure figures are preliminary and may be subject to adjustment; any such adjustment is not expected to be material. The aggregate of exploration and development costs incurred in the most recent financial year and the change during that year in estimated future development costs generally will not reflect total finding and development costs related to reserve additions for that year. Undeveloped Land ---------------- We had a total of 858,788 net acres of undeveloped land at December 31, 2008. Based on an independent land evaluation, this acreage is valued at $118 million for the Company. 2008 Year-End Financial Results and Conference Call Compton plans to release its year-end results on March 23, 2009. Additional reserve disclosures will be provided together with audited year-end financial results as at that date. Information relating to a subsequent conference call, including dial-in information, will be included in the year-end news release. Advisories Use of Boe Equivalents The oil and gas industry commonly expresses production and reserve volumes on a barrel of oil equivalent (Boe) basis whereby natural gas volumes are converted at the ratio of six thousand cubic feet of natural gas to one barrel of oil. Boe's may be misleading particularly if used in isolation. A Boe conversion ratio of 6 Mcf : 1 Bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
