PrimeEnergy Corporation

Notes to Consolidated Financial Statements

June 30, 2008

(1) Interim Financial Statements:

The accompanying
consolidated financial statements of PrimeEnergy Corporation, with the exception of the consolidated balance sheet at December 31, 2007, 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 June 30, 2008 and our income and cash flows for the six months ended June 30, 2008 and 2007. 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.

Effective January 1, 2008, the Company adopted those provisions of Statement of Financial Accounting Standards (SFAS) No. 157, Fair Value
Measurements, that were required to be adopted. There was no financial statement impact upon adoption on January 1, 2008. For further information regarding the adoption of SFAS No. 157, please refer to Note 11 of the Notes to the
Consolidated Financial Statements.

SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, including
an amendment of FASB Statement No. 115, became effective on January 1, 2008 and permits companies to choose, at specified dates, to measure certain eligible financial instruments at fair value. The provisions of SFAS No. 159
apply only to entities that elect to use the fair value option and to all entities with available-for-sale and trading securities. At the effective date, companies may elect the fair value option for eligible items that exist at that date, and the
effect of the first remeasurement to fair value must be reported as a cumulative-effect adjustment to the opening balance of retained earnings. Since the Company has not elected to adopt the fair value option for eligible items, SFAS No. 159
has not had an impact on its financial position or results of operations.

Recently Issued Accounting Standards:

In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles which identifies a consistent
framework for selecting accounting principles to be used in preparing financial statements for nongovernmental entities that are presented in conformity with United States generally accepted accounting principles (GAAP). The current GAAP hierarchy
was criticized due to its complexity, ranking position of FASB Statements of Financial Accounting Concepts and the fact that it is directed at auditors rather than entities. The statement specifies that the reporting entity, not the auditors, is
responsible for its compliance with GAAP. SFAS No. 162 will be effective 60 days following the SECs approval of the Public Company Accounting Oversight Board amendments to AU Section 411, The Meaning of Present Fairly in
Conformity with Generally Accepted Accounting Principles. The Company does not believe that SFAS No. 162 will have an impact on its financial position, result of operations or cash flows. The Company will adopt SFAS 162 when it becomes
effective.

In March 2008, the FASB issued SFAS No. 161, Disclosure about Derivative Instruments
and Hedging Activities, an amendment of FASB Statement No. 133. SFAS No. 161 amends and expands the disclosure requirements of SFAS No. 133 with the intent to provide users of financial statements with an enhanced understanding
of: (i) how and why an entity uses derivative instruments; (ii) how derivative instruments and related hedged items are accounted for under SFAS No. 133 and its related interpretations; and (iii) how derivative instruments and
related hedged items affect an entitys financial position, financial performance and cash flows. This statement is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with
early application encouraged. We are in the process of evaluating the impact of SFAS No. 161 on our consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interest in Consolidated Financial Statements, an amendment of Accounting Research Bulletin (ARB) No. 51. SFAS No. 160 clarifies that a noncontrolling
interest (previously commonly referred to as a minority interest) in a subsidiary is an ownership interest in the consolidated entity and should be reported as equity in the consolidated financial statements. The presentation of the consolidated
income statement has been changed by SFAS No. 160, and consolidated net income attributable to both the parent and the noncontrolling interest is now required to be reported separately. Previously, net income attributable to the noncontrolling
interest was typically reported as an expense or other deduction in arriving at consolidated net income and was often combined with other financial statement amounts. In addition, the ownership interests in subsidiaries held by parties other than
the parent must be clearly identified, labeled, and presented in the equity in the consolidated financial statements separately from the parents equity. Subsequent changes in a parents ownership interest while the parent retains its
controlling financial interest in its subsidiary should be accounted for consistently, and when a subsidiary is deconsolidated, any retained noncontrolling equity interest in the former subsidiary must be initially measured at fair value. Expanded
disclosures, including a reconciliation of equity balances of the parent and noncontrolling interest are also required. SFAS No. 160 is effective for fiscal years, and interim periods within those fiscal years, beginning on or after
December 15, 2008 and earlier adoption is prohibited. Prospective application is required. We are in the process of evaluating the impact of SFAS No. 160 on our consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141(R), Business Combinations. SFAS
No. 141(R) was issued in an effort to continue the movement toward the greater use of fair values in financial reporting and increased transparency through expanded disclosures. It changes how business acquisitions are accounted for and will
impact financial statements at the acquisition date and in subsequent periods. Certain of these changes will introduce more volatility into earnings. The acquirer must now record all assets and liabilities of the acquired business at fair value, and
related transaction and restructuring costs will be expensed rather than the previous method of being capitalized as part of the acquisition. SFAS No. 141(R) also impacts the annual goodwill impairment test associated with acquisitions,
including those that close before the effective date of SFAS No. 141(R). The definitions of a business and a business combination have been expanded, resulting in more transactions qualifying as business combinations.
SFAS No. 141(R) is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 31, 2008 and earlier adoption is prohibited. We cannot predict the impact that the adoption of SFAS
No. 141(R) will have on our financial position, results of operations or cash flows with respect to any acquisitions completed after December 31, 2008.

(2) Significant Acquisitions, Dispositions and Property Activity

The Company makes an annual offer to repurchase the interests of
the partners and trust unit holders in certain of the Partnerships. The Company purchased such interests in an amount totaling $153,000 is for the six months ending June 30, 2008 and $371,000 for the year ending December 31, 2007. The
Companys proportionate share of assets, liabilities and results of operations related to the interests in the Partnerships are included in the consolidated financial statements.

(3) Restricted Cash and Cash Equivalents:

Restricted cash and cash equivalents include $5,312,000 and
$3,633,000 at June 30, 2008 and December 31, 2007, respectively, of cash primarily pertaining to undistributed revenue payments. There were corresponding accounts payable recorded at June 30, 2008 and December 31, 2007 for these
liabilities.

amount, the Company capitalized $1,922,000. Capitalized interest is included as part of the cost of oil and gas properties. The capitalized rates are based upon the Companys weighted-average cost of borrowings used to finance expenditures.
There was no interest capitalized during the first half of 2008.

(6) Long-Term Debt:

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 Primes oil and gas properties. The determination of the Borrowing Base is made by the lenders taking into consideration the estimated value of Primes oil and gas properties in accordance
with the lenders customary practices for oil and gas loans. This process involves reviewing Prime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, Prime and the lenders each have discretion at any time to have the Borrowing Base re-determined. A revision to Prime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, Prime would be required to repay the excess amount within a prescribed period. If we are 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. Prime 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 June 30, 2008, the borrowing bases and outstanding balances of the Companys bank debt were $96 million and $89.6 million, respectively,
under the onshore credit facility at a weighted average interest rate of 5.92%, and $29.4 million under the offshore credit facility at a weighted average interest rate of 5.28%. Total outstanding bank debt was $119 million at June 30,2008. 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 6.03% during the first six months of 2008 as
compared to 8.89% during the same period of 2007.

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 repriced quarterly based upon the
three-month LIBOR rates.

Indebtedness to related parties  noncurrent:

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.

The current advances of this credit facility are $20 million. The facility matures in January 2010.
The new loan bears interest at the rate of 10% per annum.

(7) Other Long-Term Obligations and Commitments:

Operating Leases:

The Company has several
non-cancelable operating leases, primarily for rental of office space, that have a term of more than one year.

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 our 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 our wells, the costs to ultimately retire our wells may vary significantly from previous estimates.

(8) Contingent Liabilities:

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 June 30, 2008, 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 June 30, 2008 and 2007, options on 767,500 were outstanding and exercisable at prices
ranging from $1.00 to $1.25.

(10) Related Party Transactions:

The Company acts as the managing general partner, providing administration, accounting and tax preparation services for the Partnerships. Certain directors have limited and general partnership interests in several of
these Partnerships. As the managing general partner in each of the Partnerships, the Company receives approximately 5% to 15% of the net revenues of each Partnership as a carried interest in the Partnerships properties. The Company makes an
annual offer to repurchase the interests of the partners and trust unit holders in certain of the Partnerships. The Company purchased such interests in an amount totaling $153,000 in the second quarter 2008 and $371,000 during 2007.

Treasury stock purchases in 2008 and 2007 included shares acquired from related parties. Purchases
from related parties included a total of 70,000 shares purchased for a total consideration of $3,500,000 during the first half of 2008 and 31,700 shares purchased for a total consideration of $1,743,000 in 2007.

Due to related parties primarily represents receipts collected by the Company as agent, for the partnerships for oil and gas sales net of expenses. As of
June 30, 2008, also 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% per 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. The total due to related
parties at June 30, 2008 and December 31, 2007 was $1,179,000 and $1,563,000 respectively. Included at June 30, 2008 was $164,000 of accrued interest on the related party loan.

The Partnership agreements allow PrimeEnergy Management Corporation to receive reimbursement for property acquisition and development costs and general
and administrative overhead, incurred on behalf of the Partnerships and related party joint venture partners who are members of the Companys Board of Directors. Receivables from related parties consist of reimbursable general and
administrative costs, lease operating expenses and reimbursement for property development and related costs. Due from related parties was $281,000 at June 30, 2008 and $212,000 at December 31, 2007.

(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. The Company will adopt the provisions of FAS No. 157 covered under FSP
No. 157-2 on January 1, 2009. 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 quarter ended
June 30, 2008.

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 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 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.

Derivative Instruments and Hedging Activity:

The Company periodically enters into derivative commodity instruments to hedge its exposure to price fluctuations on natural gas and crude oil production.
At June 30, 2008, the Company had eleven cash flow hedges open: two natural gas price swap arrangements and nine crude oil collar arrangements. At June 30, 2008, $55.8 million ($35.6 million net of tax) unrealized loss was recorded in
Accumulated Other Comprehensive Income, $31.8 million and $23.8 million short-term and long-term derivative payable. Also included in Accumulated Other Comprehensive Income is unrealized gain on interest rate swaps of $835,000 ($534,000 net of tax),
and $267,000 in both short and long-term derivative assets.

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 June 30, 2008, natural gas price swaps cover 2,985 Mmcf of production
at a weighted average price of $8.04 for 2008 and $9.75 for 2009. The oil price collar covers 731 Mbbl of production at a floor price ranging from $60.00 to $65.00, a ceiling price ranging from $77.40 to $86.50 and a third-tier call of $100 on one
collar arrangement.

Assuming no change in commodity prices, after June 30, 2008, the Company would expect to reclassify to the
Statement of Operations, over the next 12 months, $20.7 million in after-tax loss associated with commodity hedges. This reclassification represents the net short-term payables associated with open positions currently not reflected in earnings at
June 30, 2008 related to anticipated remaining 2008 production and 2009 production through June.

Assuming no change in interest rates
after June 30, 2008, the Company would expect to reclassify to the statement of operations $267,000 in after tax gains associated with the interest rate swaps. This reclassification represents interest swaps which will expire within one year of
June 30, 2008.

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 repriced quarterly based upon the three-month LIBOR rates.

We are exposed to market risk on these open contracts, to the extent of changes in market prices
of natural gas and crude oil. However, the market risk exposure on these hedged contracts is generally offset by the gain or loss recognized upon the ultimate sale of the commodity that is hedged.

The preceding paragraphs contain forward-looking information concerning future production and projected gains and losses, which may be impacted both by
production and by changes in future market prices of energy commodities. See Forward-Looking Information for further details.

|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 six month period ended June 30, 2008 was $47,628,000. 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.

For 2008 we have budgeted $60 million for exploration and development in our core operating areas. As of August 2008, the Company has committed approximately $27 million on wells in these areas that have been spudded since January 1,
2008. We expect to continue to make significant capital expenditures over the next several years as part of our long-term growth strategy.

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



If our exploratory drilling results in significant new discoveries, we will have to expend additional capital in
order to finance the completion, development, and potential additional opportunities generated by our success. We believe that, because of the additional reserves resulting from the successful wells and our record of reserve growth in recent years,
we will be able to access sufficient additional capital through additional bank financing.

The Company has in place both a stock repurchase program and a
limited partnership interest repurchase program. Spending under these programs in 2007 was $4.8 million. As of June 30, 2008 the Company has expended approximately $4.5 million on these programs. The amount of treasury stock the Company may
purchase is restricted by debt convents with the Companys primary lender.

The Company currently maintains two credit facilities with a bank totaling
$360 million, with a combined current borrowing base of $119 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.

During the second quarter of 2008, the Companys offshore subsidiary arranged a subordinated credit facility with a private lender controlled by a director of the
Company. The facility provides availability of $50 million and is secured by properties released by the bank and pledged under this agreement. The current advances of this credit facility are $20 million due January 2010.

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.

RESULTS OF OPERATIONS

Revenues and net income during the six month period ended June 30, 2008, as compared to the same periods in 2007 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).

Changes in production are due to production from properties added during 2007 and early 2008 offset by the natural
decline of existing properties. The increase in oil production is related to our onshore drilling program while the change in gas production reflects the production from our offshore drilling program.

Lease operating expense for the six months of 2008 increased by $3,925,000 compared to 2007 due to the addition of lease operating expenses of new properties, increased
production taxes related to higher prices and overall price increases in oil field services.

General and administrative expenses remained flat in the first six months of 2008 as compared to 2007.

Field Service income and expense for the six months of 2008 increased $936,000 and $524,000, respectively, compared to 2007. These increases reflect higher utilization
of equipment combined with an upward trend in rates and costs during 2008.

Depreciation and depletion increased to $35,690,000 in 2008 from $20,600,000 in
2007. This increase is directly attributed to the majority of the Companys offshore properties coming on line late in 2007. These additions increased the overall property basis and production for the company

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
|------- | ----------------------------------------------------------

Interest
rate and swap activity.

The Company is exposed to interest rate risk on its line of credit, which has variable rates based upon the lenders base rate,
as defined, and the London Inter-Bank Offered rate. Based on the weighted average balances outstanding during the first half of 2008, a hypothetical 2.5% increase in the applicable interest rates would have increased interest expense for the Six
Months Ended June 30, 2008 by approximately $1,601,000.

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 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 are repriced quarterly based upon the three-month LIBOR rates.

Derivative Instruments and Hedging Activity.

Our hedging strategy is designed to reduce the risk of price volatility for our production in the natural gas and crude oil markets. Our hedging arrangements apply to
only a portion of our production and provide only partial price protection. These hedging arrangements limit the benefit to us of increases in prices, but offer protection in the event of price declines. Further, if our counterparties defaulted,
this protection might be limited as we might not receive the benefits of the hedges. Please read the discussion below and Note 11 of the Notes to Consolidated Financial Statements for a more detailed discussion of our hedging arrangements.

Hedges on Production  Collars.

From time to
time, we enter into natural gas and crude oil collar agreements with counterparties to hedge price risk associated with a portion of our production. These cash flow hedges are not held for trading purposes. Under the collar arrangements, if the
index price rises above the ceiling price, we pay the counterparty. If the index price falls below the floor price, the counterparty pays us. In the case of a three-way collar if the index price rises above the third tier price, the counterparty
pays us.

Hedges on Production  Swaps.

From time
to time, we enter into natural gas and crude oil swap agreements with counterparties to hedge price risk associated with a portion of our production. These cash flow hedges are not held for trading purposes. Under the swap agreements, if the index
price rises above the swap price, we pay the counterparty. If the index falls below the swap price, the counterparty pays us.

|ITEM 4T. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of Disclosure Controls and
Procedures

(a) Managements Quarterly Report on Internal Control Over Financial Reporting.

The Companys management is responsible for establishing and maintaining an adequate system of internal control over financial reporting (as defined in Exchange Act
Rule 13a-15(f)). Under the supervision and with the participation of our senior management, consisting of our chief executive officer and our chief financial officer, we conducted an evaluation of the effectiveness of the design and operation of our
disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this report (the Evaluation Date). Based on that evaluation,
the Companys management, including our chief executive officer and chief financial officer, concluded that as of the Evaluation Date our disclosure controls and procedures are effective such that the information relating to us required to be
disclosed in our Securities and Exchange Commission (SEC) reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to our
management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

Our
internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles
in the United States. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving
their control objectives. In evaluating the effectiveness of our internal control over financial reporting, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal
ControlIntegrated Framework. This quarterly report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Managements report was not subject to attestation by
our registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to provide only managements report in this quarterly report.

(b) Changes in Internal Control over Financial Reporting.

There were no
changes in our internal control over financial reporting that occurred during the last fiscal quarter of the period covered by this report that have materially affected or are reasonably likely to materially affect our internal control over
financial reporting.

open market transactions or negotiated sales. A total of 2,700,000 shares have been authorized, to date, under this program. Through June 30, 2008 we repurchased a total of 2,498,813 shares under this program for $32,422,977 at an average price
of $13.38 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.
