Notes to Consolidated Financial Statements

March 31, 2009

(1) Interim Financial Statements:

The accompanying consolidated financial statements of PrimeEnergy Corporation (“PEC”), with the exception of the consolidated balance sheet at December 31, 2008, have not been audited by independent public accountants. In the opinion of management, the accompanying financial statements reflect all adjustments necessary to present fairly our financial position at March 31, 2009 and our income and cash flows for the three months ended March 31, 2009 and 2008. All such adjustments are of a normal recurring nature. Certain amounts presented in prior period financial statements have been reclassified for consistency with current period presentation. The results for interim periods are not necessarily indicative of annual results.

Recently Adopted Accounting Standards

On January 1, 2009, the Company adopted Statement of Financial Accounting Standards (“SFAS”) No. 160, “Noncontrolling Interests in Consolidated Financial Statements - An Amendment of ARB No. 51” (“SFAS 160”). SFAS 160 establishes accounting and reporting standards for (1) ownership interests in subsidiaries held by others, (2) the amount of consolidated net income attributable to the controlling and noncontrolling interests, (3) changes in the controlling ownership interest, (4) the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated and (5) disclosures that clearly identify and distinguish between the interests of the controlling and noncontrolling owners. The adoption of SFAS 160 resulted in changes to our presentation for noncontrolling interests but did not have a material impact on the Company’s results of operations and financial condition. Certain prior period balances have been restated to reflect the changes required by SFAS 160.

Recently Issued Accounting Pronouncements

In April 2009, the FASB issued FSP FAS No. 115-2 and No. 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments.” FSP SFAS No. 115-2 and SFAS No. 124-2 provide additional guidance designed to create greater clarity and consistency in accounting for and presenting impairment losses on securities. FSP SFAS No. 115-2 and SFAS No. 124-2 are effective for interim and annual reporting periods beginning after June 15, 2009 and are effective for us at June 30, 2009. We have not yet determined the impact, if any, that these pronouncements will have on our results of operations or financial position.

In April 2009, the FASB issued FSP No. 157-4, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly.” FSP No.157-4 provides additional authoritative guidance to assist in determining whether a market is active or inactive, and whether a transaction is distressed. FSP No. 157-4 is effective for interim and annual reporting periods beginning after June 15, 2009 and is effective for us at June 30, 2009. We have not yet determined the impact, if any, that the FSP will have on our results of operations or financial position.

Management believes the impact of other recently issued accounting standards, which are not yet effective, will not have a material impact on our consolidated financial statements upon adoption.

On December 29, 2008, the Securities and Exchange Commission adopted rule changes to modernize its oil and gas reporting disclosures. The changes are intended to provide investors with a more meaningful and comprehensive understanding of oil and gas reserves. The updated disclosure requirements are designed to align with current practices and changes in technology that have taken place in the oil and gas industry since the adoption of the original reporting requirements more than 25 years ago.

PrimeEnergy Corporation

Notes to Consolidated Financial Statements

March 31, 2009

New disclosure requirements include:

• Permitting the use of new technologies to determine proved reserves if those technologies have been demonstrated empirically to lead to reliable conclusions about reserve volumes.

• Enabling companies to additionally disclose their probably and possible reserves to investors. Currently, the rules limit disclosure to only proved reserves.

• Allowing previously excluded resources, such as oil sands, to be classified as oil and gas reserves.

• Requiring companies to report on the independence and qualifications of a preparer or auditor and requiring companies to file reports when a third party is relied upon to prepare reserve estimates or conduct a reserves audit.

• Requiring companies to report oil and gas reserves using an average price based upon the prior 12-month period – rather than the year-end price – to maximize the comparability to reserve estimates among companies and mitigate the distortion of the estimates that arises when using a single pricing date.

(3) Restricted Cash and Cash Equivalents:

Restricted cash and cash equivalents include $8,182,000 and $8,027,000 at March 31, 2009 and December 31, 2008, respectively, of cash primarily pertaining to undistributed revenue payments.

(6) Long-Term Bank Debt:

The Company currently has credit facilities totaling $360 million, consisting of a $200 million credit facility through Guaranty Bank (the offshore facility) and a $160 million credit facility through a syndicate of banks led by Guaranty Bank (the onshore facility). The offshore facility’s maturity date is 2009 and onshore credit facility matures in 2011.

Availability under the credit facilities is based on the loan value assigned to PEC’s oil and gas properties. The determination of the Borrowing Base is made by the lenders taking into consideration the estimated value of PEC’s oil and gas properties in accordance with the lenders’ customary practices for oil and gas loans. This process involves reviewing PEC’s estimated proved reserves and their valuation. The Borrowing Base is re-determined semi-annually, and the available borrowing amount could be increased or decreased as a result of such redeterminations. In addition, PEC and the lenders each have discretion at any time to have the Borrowing Base re-determined. A revision to PEC’s reserves may prompt such a request on the part of the lenders, which could possibly result in a reduction in the Borrowing Base and availability under the credit facilities. If outstanding borrowings under either of the credit facilities exceed the applicable portion of the Borrowing Base, PEC would be required to repay the excess amount within a prescribed period. If the Company is unable to pay the excess amount, it would cause an event of default.

The credit facilities include terms and covenants that require the Company to maintain, as defined, a minimum current ratio, tangible net worth, debt coverage ratio and interest coverage ratio, and restrictions are placed on the payment of dividends and the amount of treasury stock the Company may purchase. The credit facilities are collateralized by substantially all of the Company’s assets. The Company is required to mortgage, and grant a security interest in, consolidated proved oil and gas properties. PEC also pledged the stock of several subsidiaries to the lenders to secure the credit facilities.

During the second quarter 2008, the Company entered into an amended and restated credit agreement related to the offshore credit facility allowing for a subordinated credit facility with a private lender and the release of certain collateral which was then pledged to the new lender under a separate credit agreement.

At March 31, 2009, the borrowing bases and outstanding balances of the Company’s bank debt were $112 million and $88.22 million, respectively, under the onshore credit facility at a weighted average interest rate of 4.55%, and $14.37 million under the offshore credit facility at a weighted average interest rate of 3.83%. Total outstanding bank debt was $102.59 million at March 31, 2009. The combined average interest rates paid on outstanding bank borrowings subject to interest at the bank’s base rate and on outstanding bank borrowings bearing interest based upon the LIBO rate were 4.43% during 2009 as compared to 5.64% during 2008. Beginning June 1, 2009 the onshore credit facility will be subject to a monthly borrowing base reduction of 1.2 million.

PrimeEnergy Corporation

Notes to Consolidated Financial Statements

March 31, 2009

The Company entered into interest rate hedge agreements to help manage interest rate exposure. These contracts include interest rate swaps. Interest rate swap transactions generally involve the exchange of fixed and floating rate interest payment obligations without the exchange of the underlying principal amounts. The Company entered into interest swap agreements for a period of two years, beginning in April 2008, related to $60 million of Company bank debt resulting in a fixed rate of 4.375%. The underlying debt contracts above are re-priced quarterly based upon the three-month LIBO rates.

Indebtedness to related parties—non-current:

During the second quarter 2008, the Company’s offshore subsidiary entered into a subordinated credit facility with a private lender with an availability of $50 million. The private lender has specific collateral pledged under a separate credit agreement. The private lender is a member of the Company’s Board of Directors. At March 31, 2009, advances under this credit facility were $20 million, bear interest at a rate of 10% per annum and mature in January 2010.

Subsequent to March 31, 2009, the private lender has agreed to release the pledged collateral under this credit facility in favor of the offshore credit facility in exchange for a second lien position on all of the assets of the offshore subsidiary and a pledge from PEC to not take on any additional debt on its existing asset base. This amended facility will mature in January 2012, which will be accelerated if there is a change in control, and bears interest at a rate of 10% per annum. PEC’s Board of Directors has approved these amendments and the Company expects to close this transaction in June 2009.

March 31, 2009

The Company’s liability is determined using significant assumptions, including current estimates of plugging and abandonment costs, annual inflation of these costs, the productive life of wells and the risk-adjusted interest rate. Changes in any of these assumptions can result in significant revisions to the estimated asset retirement obligation. Revisions to the asset retirement obligation are recorded with an offsetting change to producing properties, resulting in prospective changes to depreciation, depletion and amortization expense and accretion of discount. Because of the subjectivity of assumptions and the relatively long life of most of the wells, the costs to ultimately retire the wells may vary significantly from previous estimates.

(8) Contingent Liabilities:

PrimeEnergy Management Corporation, a wholly-owned subsidiary, acts as the managing general partner for 18 limited partnerships and 2 trusts (collectively, the “Partnerships”). The Company, as managing general partner of the affiliated Partnerships, is responsible for all Partnership activities, including the drilling of development wells and the production and sale of oil and gas from productive wells. The Company also provides the administration, accounting and tax preparation work for the Partnerships, and is liable for all debts and liabilities of the affiliated Partnerships, to the extent that the assets of a given limited Partnership are not sufficient to satisfy its obligations. As of March 31, 2009, the affiliated Partnerships have established cash reserves in excess of their debts and liabilities and the Company believes these reserves will be sufficient to satisfy Partnership obligations.

The Company is subject to environmental laws and regulations. Management believes that future expenses, before recoveries from third parties, if any, will not have a material effect on the Company’s financial condition. This opinion is based on expenses incurred to date for remediation and compliance with laws and regulations which have not been material to the Company’s results of operations.

(9) Stock Options and Other Compensation:

In May 1989, non-statutory stock options were granted by the Company to four key executive officers for the purchase of shares of common stock. At March 31, 2009 and 2008, options on 767,500 were outstanding and exercisable at prices ranging from $1.00 to $1.25.

(10) Related Party Transactions:

The Company makes an annual offer to repurchase the interests of the partners and trust unit holders in certain of the Partnerships and Trusts. The Company did not purchase any interests in the Partnerships or Trusts for the three months ending March 31, 2009. The amount purchased for the year ending December 31, 2008 was $481,000.

Treasury stock purchases in any reported period may include shares acquired from a related party. There were no related party treasury stock purchases during the first quarter of 2009. Purchases from related parties in 2008 included 70,000 shares purchased for a total consideration of $3,500,000.

Receivables from related parties consist of reimbursable general and administrative costs, lease operating expenses and reimbursement for property development and related costs. These receivables are due from joint venture partners, which may include members of the Company’s Board of Directors.

Payables owed to related parties primarily represent receipts collected by the Company as agent for the joint venture partners, which may include members of the Company’s Board of Directors, for oil and gas sales net of expenses. Also included in due to related parties is the amount of accrued interest owed to the related party, a member of the Company’s Board of Directors, with whom the Company’s offshore subsidiary entered into a credit agreement. The agreement provides for a loan of $20 million at a rate of 10% annum and is secured by certain oil and gas properties and the Company’s interest in a limited partnership which owns a shopping center in Alabama. Included at March 31, 2009 was $170,000 of accrued interest on the related party loan.

(11) Financial Instruments

Adoption of SFAS No. 157

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” which establishes a formal framework for measuring fair values of assets and liabilities in financial statements that are already required by United States generally accepted accounting principles to be measured at fair value. SFAS No. 157 clarifies guidance in FASB Concepts Statement (CON) No. 7 which discusses present value techniques in measuring fair value. Additional disclosures are also required for transactions measured at fair value. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. In February 2008, the FASB issued FASB Staff Position (FSP) No. FAS 157-2, “Effective Date of FASB Statement No. 157,” which granted a one year deferral (to fiscal years beginning after November 15, 2008, and interim periods within those fiscal years) for certain non-financial assets and liabilities to comply with SFAS No. 157. Additionally, in February 2008, the FASB issued FSP No. FAS 157-1, “Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurements for Purposes of Lease Classification or Measurement under Statement 13,” which amends SFAS No. 157 to exclude SFAS No. 13 and related pronouncements that address fair value measurements for purposes of lease classification and measurement. FSP No. FAS 157-1 is effective upon the initial adoption of SFAS No. 157. The Company has adopted SFAS No. 157 and the related FSPs discussed above which did not have an impact on its financial position or results of operations for the year ended March 31, 2009.

As defined in SFAS No. 157, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The transaction is based on a hypothetical transaction in the principal or most advantageous market considered from the perspective of the market participant that holds the asset or owes the liability.

The valuation techniques that can be used under SFAS No. 157 are the market approach, income approach or cost approach. The market approach uses prices and other information for market transactions involving identical or comparable assets or liabilities, such as matrix pricing. The income approach uses valuation techniques to convert future amounts to a single discounted present amount based on current market conditions about those future amounts, such as present value techniques, option pricing models (i.e. Black-Scholes model) and binomial models (i.e. Monte-Carlo model). The cost approach is based on current replacement cost to replace an asset.

The Company utilizes market data or assumptions that market participants who are independent, knowledgeable and willing and able to transact would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. The Company attempts to utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company is able to classify fair value balances based on the observability of those inputs. SFAS No. 157 establishes a formal fair value hierarchy based on the inputs used to measure fair value. The hierarchy gives the highest priority level 1 measurements and the lowest priority to level 3 measurements, and accordingly, level 1 measurements should be used whenever possible.

The three levels of the fair value hierarchy as defined by SFAS No. 157 are as follows:

• Level 1: Valuations utilizing quoted, unadjusted prices for identical assets or liabilities in active markets that the Company has the ability to access. This is the most reliable evidence of fair value and does not require a significant degree of judgment. Examples include exchange-traded derivatives and listed equities that are actively traded.

• Level 2: Valuations utilizing quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly for substantially the full term of the asset or

17

Notes to Consolidated Financial Statements

March 31, 2009

liability. Financial instruments that are valued using models or other valuation methodologies are included. Models used should primarily be industry-standard models that consider various assumptions and economic measures, such as interest rates, yield curves, time value, volatilities, contract terms, current market prices, credit risk or other market-corroborated inputs. Examples include most over-the-counter derivatives (non-exchange traded), physical commodities, most structured notes and municipal and corporate bonds.

• Level 3: Valuations utilizing significant, unobservable inputs. This provides the least objective evidence of fair value and requires a significant degree of judgment. Inputs may be used with internally developed methodologies and should reflect an entity’s assumptions using the best information available about the assumptions that market participants would use in pricing an asset or liability. Examples include certain corporate loans, real-estate and private equity investments and long-dated or complex over-the-counter derivatives.

Depending on the particular asset or liability, input availability can vary depending on factors such as product type, longevity of a product in the market and other particular transaction conditions. In some cases, certain inputs used to measure fair value may be categorized into different levels of the fair value hierarchy. For disclosure purposes under SFAS No. 157, the lowest level that contains significant inputs used in valuation should be chosen. Per SFAS No. 157, the Company has classified its assets and liabilities into these levels depending upon the data relied on to determine the fair values. The fair values of the Company’s natural gas and crude oil price collars and swaps are valued based upon quotes obtained from counterparties to the agreements and are designated as Level 3.

The following fair value hierarchy table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2009:

	Quoted Prices in Active Markets For Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)			Balance as of March 31, 2009
Assets
Commodity Derivative Contracts	—	—	$	1,714,000		$	1,714,000
Total Assets	—	—	$	1,714,000		$	1,714,000
Liabilities
Interest Rate Derivative Contracts	—	—	$	(501,000	)	$	(501,000	)
Total Liability	—	—	$	(501,000	)	$	(501,000	)

The derivative contracts were measured based on quotes from the Company’s counterparties. Such quotes have been derived using a model that considers various inputs including current market and contractual prices for the underlying instruments, quoted forward prices for natural gas and crude oil, volatility factors and interest rates, such as a LIBOR curve for a similar length of time as the derivative contract term. Although the Company utilizes multiple quotes to assess the reasonableness of its values, the Company has not attempted to obtain sufficient corroborating market evidence to support classifying these derivative contracts as Level 2.

The following table sets forth a reconciliation of changes in the fair value of financial assets and liabilities classified as level 3 in the fair value hierarchy.

Net assets as of January 1, 2009	$	1,578,000

Notes to Consolidated Financial Statements

March 31, 2009

(a) Amounts reported in net income are classified as oil and gas sales for commodity derivative instruments and as a reduction to interest expense for interest rate swap instruments.

The Company periodically enters into derivative commodity instruments to hedge its exposure to price fluctuations on natural gas and crude oil production. At March 31, 2009 the Company has seven crude oil collar arrangements open. At March 31, 2009, $1.213 million ($775 thousand net of tax) unrealized gain was recorded in Accumulated Other Comprehensive Income, along with a $1.476 million and $238 thousand short-term and long-term derivative receivable and $494 thousand and $7 thousand in short-term and long-term derivative payables. The change in the fair value of derivatives designated as hedges that is effective is initially recorded to Accumulated Other Comprehensive Income. The ineffective portion, if any, of the change in the fair value of derivatives designated as hedges, and the change in fair value of all other derivatives, is recorded currently in earnings as a component of oil and gas sales.

As of March 31, 2009, the oil price collars cover 492 Mbbl of production at a floor price ranging from $60.00 to $65.00, and a ceiling price ranging from $77.40 to $86.50.

Assuming no change in commodity prices, after March 31, 2009, the Company would expect to reclassify to the Statement of Operations, over the next 12 months, $944 thousand in after-tax income associated with commodity hedges. This reclassification represents the net short-term receivable associated with open positions currently not reflected in earnings at March 31, 2009 related to anticipated 2009 production.

(12) Earnings Per Share:

Basic earnings per share are computed by dividing earnings available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect per share amounts that would have resulted if dilutive potential common stock had been converted to common stock. The following reconciles amounts reported in the financial statements:

	Three Months Ended March 31, 2009							Three Months Ended March 31, 2008
	Net Income/(loss)			Number of Shares	Per Share Amount			Net Income		Number of Shares	Per Share Amount
Net income/(loss) per common share	$	(3,498,000	)	3,044,745	$	(1.15	)	$	2,731,000	3,090,276	$	0.88

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This discussion should be read in conjunction with the financial statements of the Company and notes thereto.

LIQUIDITY AND CAPITAL RESOURCES

Cash flow provided by operations for the three month period ended March 31, 2009 was $10,959,000. Excluding the effects of significant unforeseen expenses or other income, our cash flow from operations fluctuates primarily because of variations in oil and gas production and prices or changes in working capital accounts. Our oil and gas production will vary based on actual well performance but may be curtailed due to factors beyond our control. Hurricanes in the Gulf of Mexico may shut down our production for the duration of the storm’s presence in the Gulf or damage production facilities so that we cannot produce from a particular property for an extended amount of time. In addition, downstream activities on major pipelines in the Gulf of Mexico can also cause us to shut-in production for various lengths of time.

Our realized oil and gas prices vary due to world political events, supply and demand of products, product storage levels, and weather patterns. We sell the vast majority of our production at spot market prices. Accordingly, product price volatility will affect our cash flow from operations. To mitigate price volatility we sometimes lock in prices for some portion of our production through the use of financial instruments.

The Company’s activities include development and exploratory drilling. The Company’s strategy is to develop a balanced portfolio of drilling prospects that includes lower risk wells with a high probability of success and higher risk wells with greater economic potential.

The Company’s strategy in 2009 is to continue to reduce its outstanding debt which decreased by $30,860,000 in 2008. This decreased leveraged position will better provide the Company the ability to participate in a significant acquisition, should the opportunity arise this year.

20

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

The Company has in place both a stock repurchase program and a limited partnership interest repurchase program. Spending under these programs in 2008 was $5.03 million. The Company expects to expend substantially less in 2009 because of the drop in energy prices. During the first quarter of 2009 the Company spent only $225,000 under these programs.

The Company currently maintains two credit facilities totaling $360 million, with a combined current borrowing base of $126.37 million. The bank reviews the borrowing base semi-annually and, at their discretion, may decrease or propose an increase to the borrowing base relative to a redetermined estimate of proved oil and gas reserves. Our oil and gas properties are pledged as collateral for the line of credit and we are subject to certain financial covenants defined in the agreement. We are currently in compliance with these financial covenants. If we do not comply with these covenants on a continuing basis, the lenders have the right to refuse to advance additional funds under the facility and/or declare all principal and interest immediately due and payable.

In April 2008, the Company entered into an amended and restated credit agreement related to the offshore credit facility allowing for a subordinated credit facility with a private lender and the release of certain collateral which was then pledged to the new lender under a separate credit agreement.

Pursuant to these agreements the offshore credit facility with the bank is $14.37 million which matures in 2009 and the subordinated credit facility is $20 million due January 2010. The subordinated credit facility was provided by a related party and bears interest at the rate of 10% per annum. Currently, the private lender has agreed to release the pledged collateral under this credit facility in favor of the offshore credit facility in exchange for a second lien position on all of the assets of the offshore subsidiary and a pledge from PEC to not take on any additional debt on its existing asset base. This amended facility will mature in January 2012, which will be accelerated if there is a change in control, and bears interest at a rate of 10% per annum. PEC’s Board of Directors has approved these amendments and the Company expects to close this transaction in June 2009.

It is the goal of the Company to increase its oil and gas reserves and production through the acquisition and development of oil and gas properties. The Company also continues to explore and consider opportunities to further expand its oilfield servicing revenues through additional investment in field service equipment. However, the majority of the Company’s capital spending is discretionary, and the ultimate level of expenditures will be dependent on the Company’s assessment of the oil and gas business environment, the number and quality of oil and gas prospects available, the market for oilfield services, and oil and gas business opportunities in general.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

RESULTS OF OPERATIONS

Revenues and net income during the three month period ended March 31, 2009, as compared to the same periods in 2008 reflect the increased oil and gas sales, presented below, offset by exploration costs and depreciation and depletion of oil and gas properties. The table summarizes production volumes and average sales prices realized (including realized gains and losses from derivatives).

	Three Months Ended March 31,
					Increase /
	2009		2008		(Decrease)
Barrels of Oil Produced		172,000		156,000		16,000
Average Price Received	$	44.00	$	78.45	$	(34.35	)
Oil Revenue	$	7,575,000	$	12,238,000	$	(4,663,000	)
Mcf of Gas Produced		1,871,000		2,382,000		(511,000	)
Average Price Received	$	4.52	$	9.18	$	(4.66	)
Gas Revenue	$	8,463,000	$	21,863,000	$	(13,400,000	)
Total Oil & Gas Revenue	$	16,038,000	$	34,101,000	$	(18,063,000	)

Oil and gas prices received excluding the impact of derivatives were;

	Three Months Ended March 31,
	2009		2008		Increase / (Decrease)
Oil Price	$	36.96	$	88.20	$	(51.24	)
Gas Price	$	4.52	$	8.77	$	(4.25	)

The increase in oil production is due to properties added during 2008 from our 2008 West Texas drilling program offset by the natural decline of existing properties. The decrease in gas production is primarily due to the natural decline of the offshore properties.

Lease operating expense for the three months of 2009 decreased by $1,479,000 compared to 2008 due to overall price decreases in oil field services combined with reduced production taxes related to reduced commodity prices.

22

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

General and administrative expenses decreased $368,000 in the first three months of 2009 as compared to 2008 due to reductions in personnel costs.

Field Service income and expense for the three months of 2009 decreased $1,297,000 and $714,000, respectively, compared to 2008. These decreases reflect lower rates and labor costs during 2009.

Depreciation, depletion and amortization expense decreased to $11,768,000 in 2009 from $16,920,000 in 2008. This decrease is primarily related to the decrease in offshore production during the first quarter of 2009.

This Report contains forward-looking statements that are based on management’s current expectations, estimates and projections. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “projects” and “estimates,” and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, and are subject to the safe harbors created thereby. These statements are not guarantees of future performance and involve risks and uncertainties and are based on a number of assumptions that could ultimately prove inaccurate and, therefore, there can be no assurance that they will prove to be accurate. Actual results and outcomes may vary materially from what is expressed or forecast in such statements due to various risks and uncertainties. These risks and uncertainties include, among other things, the possibility of drilling cost overruns and technical difficulties, volatility of oil and gas prices, competition, risks inherent in the Company’s oil and gas operations, the inexact nature of interpretation of seismic and other geological and geophysical data, imprecision of reserve estimates, and the Company’s ability to replace and expand oil and gas reserves. Accordingly, stockholders and potential investors are cautioned that certain events or circumstances could cause actual results to differ materially from those projected.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is a smaller reporting company and no response is required pursuant to this Item.

23

Item 4. CONTROLS AND PROCEDURES

As of the end of the current reported period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15of the Securities Exchange Act of 1934 (the “Exchange Act”). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective, in all material respects, with respect to the recording, processing, summarizing and reporting, within the time periods specified in the Commission’s rules and forms, of information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act.

There were no significant changes in the Company’s internal control over financial reporting that occurred during the first quarter of 2009 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

(1) In December 1993, we announced that our board of directors authorized a stock repurchase program whereby we may purchase outstanding shares of our common stock from time-to-time, in open market transactions or negotiated sales. A total of 2,700,000 shares have been authorized, to date, under this program. Through March 31, 2009 we repurchased a total of 2,509,113 shares under this program for $33,885,322 at an average price of $13.50 per share. Additional purchases may occur as market conditions warrant. We expect future purchases will be funded with internally generated cash flow or from working capital.
