FINANCIAL GUIDANCE DISCLOSURES FOR 2010

Overview

Clayton Williams Energy, Inc. and its subsidiaries have prepared this document to provide public disclosure of certain financial and operating estimates in order to permit the preparation of models to forecast our operating results for each quarter during the year ending December 31, 2010. These estimates are based on information available to us as of the date of this filing, and actual results may vary materially from these estimates. We do not undertake any obligation to update these estimates as conditions change or as additional information becomes available.

The estimates provided in this document are based on assumptions that we believe are reasonable. Until our actual results of operations for these periods have been compiled and released, all of the estimates and assumptions set forth herein constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included in this document that address activities, events or developments that we expect, project, believe or anticipate will or may occur in the future, or may have occurred through the date of this filing, including such matters as production of oil and gas, product prices, oil and gas reserves, drilling and completion results, capital expenditures and other such matters, are forward-looking statements. Such forward-looking statements involve known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from the results, performance, or achievements expressed or implied by such forward-looking statements. Such factors include, among others, the following: the volatility of oil and gas prices; the unpredictable nature of our exploratory drilling results; the reliance upon estimates of proved reserves; operating hazards and uninsured risks; competition; government regulation; and other factors referenced in filings made by us with the Securities and Exchange Commission.

As a matter of policy, we generally do not attempt to provide guidance on:

    (a)   production which may be obtained through future exploratory drilling; (b) dry hole and abandonment costs that may result from future exploratory drilling; (c) the effects of Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities” superseded by topic 815-10 of the Financial Accounting Standards Board Accounting Standards Codification; (d) gains or losses from sales of property and equipment unless the sale has been consummated prior to the filing of financial guidance; (e) capital expenditures related to completion activities on exploratory wells or acquisitions of proved properties until the expenditures are estimable and likely to occur; and (f) revenues and expenses related to Desta Drilling, L.P., a wholly-owned subsidiary of the Company which provides contract drilling services for the Company.

Summary of Estimates

The following table sets forth actual and certain estimates being used by us to model our anticipated results of operations for each quarter during the fiscal year ending December 31, 2010. When a single value is provided, such value represents the mid-point of the approximate range of estimates. Otherwise, each range of values provided represents the expected low and high estimates for such financial or operating factor. See “Supplementary Information.”

Capital Expenditures

The following table sets forth, by area, our actual expenditures for exploration and development activities for the nine months of 2010 and our planned expenditures for the year ending December 31, 2010.

      Actual Planned Expenditures Expenditures 2010 Nine Months Ended Year Ended Percentage September 30, 2010 December 31, 2010

We currently plan to spend approximately $304.1 million on exploration and development activities in fiscal 2010, $209 million of which was incurred during the first nine months of 2010. Our actual expenditures during fiscal 2010 may be substantially higher or lower than these estimates since our plans for exploration and development activities may change during the year. Other factors, such as prevailing product prices and the availability of capital resources, could also increase or decrease the ultimate level of expenditures during fiscal 2010.

Based on these current estimates, approximately 96% of our planned expenditures for exploration and development activities for fiscal 2010 will relate to developmental prospects, as compared to approximately 60% in fiscal 2009.

Accounting for Derivatives

The following summarizes information concerning our net positions in open commodity derivatives applicable to periods subsequent to September 30, 2010. The settlement prices of commodity derivatives are based on NYMEX futures prices.

(a) One MMBtu equals one Mcf at a Btu factor of 1,000.  

In March 2009, we terminated certain fixed-priced oil swaps covering 77,000 barrels at a price of $57.35 from October 2010 through December 2010, resulting in an aggregate loss of approximately $312,000, which will be paid to the counterparty monthly as the applicable contracts are settled.

We did not designate any of the derivatives shown in the preceding table as cash flow hedges; therefore, all changes in the fair value of these contracts prior to maturity, plus any realized gains or losses at maturity, will be recorded as other income (expense) in our statement of operations.
