Exhibit 99.4

SUPPLEMENTAL OIL AND GAS DISCLOSURES (UNAUDITED)

The following tables summarize the net ownership interest in the proved oil and gas reserves and the standardized measure of discounted future net cash flows related to the proved oil and gas reserves for the Properties and are derived from the reserve reports prepared for Titan Operating, LLC (“The Company”) and annual financial statements for the years ended December 31, 2011, 2010 and 2009. For these periods, independent third-party reserve engineers were retained to prepare a report of proved oil and gas reserves related to the Company. The standardized measure presented here excludes income taxes as the Company is a limited liability company and is not liable for federal income taxes. The proved oil and gas reserve estimates and other components of the standardized measure were determined in accordance with the authoritative guidance of the Financial Accounting Standards Board and the SEC.

Proved Oil and Gas Reserve Quantities

Proved oil and gas reserves are those quantities of oil and gas, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. Proved developed reserves are proved reserves that can be expected to be recovered through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well. Proved undeveloped reserves are proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. The net proved oil and gas reserves and changes in net proved oil and gas reserves attributable to the Company’s properties, all of which are located in the state of Texas, are summarized below:

Capitalized Costs Related to Oil and Gas Producing Activities

The components of capitalized costs related to oil and gas producing activities of the Company during the periods indicated were as follows:

Costs Incurred

The following table summarizes costs incurred and capitalized in oil and natural gas property acquisition, exploration and development activities:

Oil and Natural Gas Operating Results

Results of operations from oil and natural gas producing activities were as follows:

Standardized Measure

Pursuant to SEC guidelines, the standardized measure utilizes the unweighted trailing 12-month arithmetic average of the first of month natural gas and crude oil benchmark prices. The average prices used for 2011, 2010 and 2009 under these rules were $96.19 and $79.43, and N/A per barrel, respectively, for crude oil, condensate, and natural gas liquids (WTI - Cushing, Oklahoma), and $4.12, $4.38 and $3.87 per MMbtu, respectively, for natural gas (Henry Hub).

Future cash inflows were reduced by estimated future production, development and abandonment costs based on current cost, with no escalation to determine pre-tax cash inflows. As mentioned above, the standardized measure presented below does not include the effects of income taxes as the Company is not subject to income tax. A discount factor of 10% was used to reflect the timing of future net cash flows. The standardized measure of discounted future net cash flows is not intended to represent the replacement cost or fair value of the Properties. An estimate of fair value would also take into account, among other things, the recovery of reserves not presently classified as proved, anticipated future changes in prices and costs, and a discount factor more representative of the time value of money and the risks inherent in oil and gas reserve estimates.

The standardized measure of discounted future net cash flows before income taxes related to the proved oil and gas reserves of the Company’s properties is as follows:
