We have provided definitions for some of the oil and natural gas industry terms used in this prospectus in the “Glossary of Oil and Natural Gas Terms” in Appendix A.

We are an independent oil and natural gas exploration and production company with properties located along the Louisiana Gulf Coast. Our operations are concentrated in two fields: West Cote Blanche Bay, or WCBB, and East Hackberry. As of December 31, 2005, we had 23.2 MMboe of proved reserves, of which 84% was oil, with a present value of estimated future net revenues, discounted at 10%, or PV-10, of approximately $456.9 million and associated standardized measure of discounted future net cash flows of approximately $369.8 million. See “—Summary of Operating and Reserve Data” for our definition of PV-10, a non-GAAP financial measure, and a reconciliation of our standardized measure of discounted future net cash flows to PV-10. Our 2005 production was 84% oil.

We seek to achieve reserve and production growth and increase our cash flow through our annual drilling programs. In 2005, we drilled 17 wells and recompleted 11 existing wells in our WCBB field for an estimated aggregate cost of $21.1 million. Of our 17 new wells, nine were completed as producing wells, seven were waiting to be completed at year end (one of which will be side-tracked in 2006 to test deeper zones) and one was a dry hole. During 2006, we intend to drill 22 wells and recomplete 18 existing wells at our WCBB field for an estimated aggregate cost of $33.2 million. As of April 18, 2006, we had drilled ten new wells of which eight are awaiting completion and two were dry holes. During 2005, we completed a 3-D seismic program at our East Hackberry field, to enhance our drilling program at that field, and we currently intend to drill up to six wells in 2006 for an estimated aggregate cost of $13.3 million.

WCBB. The WCBB field lies approximately five miles off the coast of Louisiana in a shallow bay with water depths averaging eight to ten feet. We own a 100% working interest (79.4% NRI), and are the operator, in depths above the base of the 13900 Sand which is located at 11,320 feet. In addition, we own a 40.4% non-operated working interest (30.0% NRI) in depths below the base of the 13900 Sand, which is operated by Chevron Corporation. Our leasehold interests at WCBB contain 5,668 gross acres. Texaco drilled the discovery well in this field in 1940. Of the 846 wells drilled as of December 31, 2005, 766 were completed as producing wells. As a result, the field has a historic success rate of 90% for all wells drilled. As of December 31, 2005, estimated field cumulative gross production was 232 MMboe. During the first half of 2005, we reprocessed a 70 square mile 3-D seismic survey using the most recent advances in seismic data processing. This reprocessed data has helped and will continue to help us add to our inventory of identified drilling locations. Since our acquisition of WCBB in 1997, we have drilled 62 new wells, seven of which were dry holes, for an 89% success rate. We have also recompleted 57 wells resulting in 44 producing wells. Our inventory of prospects includes approximately 120 PUD wells, many of which are up-dip offsets to wells that produced from a sub-optimum position within a particular zone. The drilling schedule used in our December 31, 2005 reserve report anticipates that all of those wells will be drilled by 2015. In addition, we have identified over 100 more developmental and exploratory prospects which include several deep natural gas prospects, one of which we intend to drill in 2006.

East Hackberry. The East Hackberry field is located along the western shore of Lake Calcasieu in Louisiana, 15 miles inland from the Gulf of Mexico. We own a 100% working interest (approximately 79% average NRI) in certain producing oil and natural gas properties situated in the East Hackberry field. The interest includes two separate lease blocks, the Erwin Heirs Block, which is located on land, and the adjacent State Lease 50 Block, which is located primarily in the shallow waters of Lake Calcasieu. The two lease blocks together contain 3,147 acres. The East Hackberry field was discovered in 1926 by Gulf Oil Company. The estimated field cumulative oil and condensate production through 2005 was approximately 56 MMboe. We have received and are currently reviewing our proprietary 3-D seismic survey of 42 square miles in and around the East Hackberry field. Since this portion of the East Hackberry field has never been included in a 3-D seismic survey, we anticipate the data will reveal undrilled fault blocks that will allow us to drill new wells to both shallow and deep targets in the field.

Due to the impact of Hurricanes Katrina and Rita, much of our production was shut-in in the fourth quarter of 2005 and the first quarter 2006. As a result, total production in the fourth quarter of 2005 was 22.4 Mboe and total estimated production in the first quarter of 2006 was 80.6 Mboe.

WCBB. We sustained no damage to our facilities at WCBB from Hurricane Katrina which made landfall on August 29, 2005. Prior to that storm, both our Hackberry and WCBB facilities were shut-in and evacuated for four days for precautionary reasons. In our WCBB field, we used the shut-in period to implement tie-in points for future facilities upgrades.

In preparation for Hurricane Rita, on September 21, 2005, we began shutting-in production and evacuating personnel from our WCBB field. On September 24, 2005, the tidal surge from Hurricane Rita caused damage to our WCBB facilities. Our main tank batteries, which handled approximately 70% of our production before Hurricane Rita, again became operational during the first quarter of 2006. We anticipate that the balance of our production facilities at WCBB will be brought on line in the second and third quarters of 2006. We began returning wells to production during the first quarter of 2006, and as of April 18, 2006, 27 of the 57 active wells in the field prior to Hurricane Rita had been returned to production on an intermittent basis. We continue to reactivate our remaining shut-in WCBB wells and are in the process of completing 15 that have been drilled after Hurricane Rita but not completed due to the damage to our facilities caused by that storm. We expect that all of these wells will begin producing during the second quarter of 2006.

On September 20, 2005, prior to Hurricane Rita, aggregate net production at WCBB was 2,204 Boe. We lost more than 100 days of production but have since resumed production at WCBB from 27 of the 57 wells that were active prior to Hurricane Rita, with aggregate net production ranging from 1,754 Boe to 3,032 Boe per day during the period March 20, 2006 through March 30, 2006. Aggregate net production from WCBB during the first quarter of 2006 was 59.1 Mboe.

East Hackberry Field. On September 20, 2005, prior to shutting-in our 11 producing East Hackberry wells in preparation for Hurricane Rita, aggregate net production was approximately 299 Boe per day. Production was re-established from six of these wells in November 2005, and during the period March 20, 2006 through March 30, 2006, aggregate net production from these wells ranged from approximately 181 Boe to 219 Boe per day. Due to damage to certain of our production facilities caused by Hurricane Rita, five wells in our State Lease 50 Block remain shut-in. Prior to being shut-in, these five wells had aggregate production of approximately 50 Boe per day. We have budgeted $8.0 million to replace and upgrade certain of our East Hackberry facilities in connection with our 2006 drilling program and intend to put the five remaining shut-in wells back on line when these facilities are completed. Aggregate net production from the East Hackberry field during the first quarter of 2006 was 14.6 Mboe.

Insurance Coverage. As of December 31, 2005, we had incurred costs of $3.2 million relating to the damage to our WCBB fields and facilities caused by Hurricane Rita. As of April 10, 2006, we had incurred an additional $2.6 million in hurricane related costs subsequent to December 31, 2005 at WCBB. Based upon consultations with insurance adjustors and review of our policies, we believe this entire amount will be covered by our insurance. We had no insurance coverage for property damage to our East Hackberry facilities. We also maintain business interruption insurance to cover lost production revenue in the event of shut-in production. The business interruption insurance begins 60 days after the occurrence of an insurable event, subject to a daily limit of $45,000 and has a maximum coverage of 180 days. Coverage began on November 24, 2005 for shut-in production caused by Hurricane Rita. During 2005, we accrued $1.7 million of business interruption insurance recoveries in other income in our statement of operations, which was received subsequent to year end.

We believe that our following strengths will help us achieve our business goals:

High quality asset base with a long reserve life. Our reserves are concentrated in two fields that have historically produced significant volumes of hydrocarbons from multiple geologic horizons. As of December 31, 2005, our proved developed reserves to production ratio was over six years. We believe this relatively stable base of long-lived production from multiple geologic horizons is a strong platform to support further growth in our reserves and production.

Experienced management and technical team. Our management and technical personnel have an average of 25 years of experience in the oil and natural gas industry, including two geophysicists who have worked together for over 25 years and together have participated in drilling over 60 wells in the Gulf Coast region.

Substantial drilling inventory. We have assembled an inventory of approximately 120 PUD locations and over 100 developmental and exploratory prospects. At our current pace of drilling, we believe we have over seven years of drilling inventory. We believe there are substantial opportunities to expand our exploration activities on our existing leasehold acreage position, particularly by exploring deeper gas prospects.

Operate core properties. We serve as operator of the WCBB field above the 13900 Sand and of our East Hackberry field. As operator, we can manage all phases of a project’s drilling and development operations. This

allows us to exercise greater control over the cost, timing and scope of our activities and more effectively use our platforms, processing facilities and flowlines.

Concentrated drilling operations. By drilling our wells in a relatively small geographic area, our mobilization costs are lower and the time required to move between wells is relatively short. Our ongoing, concentrated operations have also enabled us to refine our drilling and well completion techniques and maintain continuous use of key equipment. These factors can help reduce the cost to drill and complete our wells.

Technical approach. Substantially all of our drilling prospects are generated internally by our technical team using advanced technology in analyzing, interpreting and visualizing 3-D seismic data. We have reprocessed existing 3-D seismic data at WCBB and undertaken a new 3-D seismic survey at East Hackberry. We believe that our 94% drilling success rate at WCBB since 2003 is attributable to our technical knowledge of the field and our effective use of 3-D seismic data and subsurface geological mapping.

Our goal is to increase stockholder value by investing in development and select exploration projects intended to grow our production and reserves and increase our cash flow while generating attractive rates of return. We seek to achieve this goal through the following:

Apply advanced technologies to enhance recoveries and grow production and reserves. We believe that our use of 3-D seismic data will help us identify prospective locations that were not visible using the older 2-D data that was primarily used in the development of the WCBB and East Hackberry fields. In addition, we primarily use directional drilling techniques that allow us to penetrate multiple prospects from each well bore increasing our potential reserve quantities and limiting exploration and development risk.

Focus on lower risk oil development projects, with selective expenditures on higher risk natural gas exploration projects. Many of our WCBB drilling locations are primarily shallow oil targets that are structurally up-dip to existing or historical production or located in undrilled fault blocks. We believe that by focusing our drilling budget on development oriented activities we can maintain high drilling success rates yielding attractive production and reserve growth. Our drilling program has achieved a success rate of 94% since 2003. We also plan to allocate a portion of our budget to drill higher impact, but higher risk, natural gas exploration prospects. In 2006, we plan to spend approximately 15% of our total drilling capital targeting natural gas prospects.

Financial flexibility. We seek to maintain a conservative financial position and believe that our operating cash flow will provide us with the financial flexibility to pursue our planned development and exploration activities through 2006.

Investing in our common stock involves risks that include the speculative nature of oil and natural gas exploration, competition, volatile oil and natural gas prices and other material factors. You should read carefully the section of this prospectus entitled “Risk Factors” beginning on page 11 for an explanation of these risks before investing in our common stock. In particular, the following considerations may offset our competitive strengths or have a negative effect on our strategy as well as activities on our properties, which could cause a decrease in the price of our common stock and a loss of all or part of your investment:

Risks relating to the development of oil and natural gas reserves. Our oil and natural gas reserves and future production and, therefore, our future cash flow and income are highly dependent on our ability to successfully execute our drilling program, which will require substantial amounts of capital.

Risks relating to oil and natural gas reserve estimates. Reserve estimates are based on many assumptions and our properties may not produce the reserves we originally forecast. Our reserves will decline unless we are successful in finding or acquiring new reserves.

Access to equipment and personnel. Shortages of drilling rigs, equipment, supplies or personnel could delay, restrict or increase the cost of our exploration, exploitation and development operations, which in turn could impair our financial condition and results of operations.

Concentration in Louisiana. Our operations are concentrated in Louisiana. As a result, we may be disproportionately exposed to impacts of delays or interruptions of production from this region caused by hurricanes or other natural disasters, significant governmental regulation or lack of field infrastructure.

For a discussion of other considerations that could negatively affect us, see “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”

The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment.

The volatility of oil and natural gas prices due to factors beyond our control greatly affects our profitability.

Our revenues, operating results, profitability, future rate of growth and the carrying value of our oil and natural gas properties depend primarily upon the prevailing prices for oil and natural gas. Historically, oil and natural gas prices have been volatile and are subject to fluctuations in response to changes in supply and demand, market uncertainty and a variety of additional factors that are beyond our control, including:

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and natural gas price movements with any certainty. The West Texas Intermediate posted price for crude oil on December 31, 2004 was $43.45 per Bbl and the Henry Hub spot market price of natural gas on December 31, 2004 was $6.21 per MMBtu and at December 31, 2003 were $32.52 per Bbl and $6.19 per MMBtu. The West Texas Intermediate posted price for crude oil on December 31, 2005 was $57.75 per Bbl and the Henry Hub spot market price of natural gas on December 31, 2005 was $10.08 per MMBtu. Any substantial decline in the price of oil and natural gas will likely have a material adverse effect on our operations, financial condition and level of expenditures for the development of our oil and natural gas reserves, and may result in write downs of oil and natural gas properties due to ceiling test limitations.

Our success depends on finding, developing or acquiring additional reserves.

Our future success depends upon our ability to find, develop or acquire additional oil and natural gas reserves that are economically recoverable. Our proved reserves will generally decline as reserves are depleted, except to the extent that we conduct successful exploration or development activities or acquire properties containing proved reserves, or both. To increase reserves and production, we undertake development, exploration and other replacement activities or use third parties to accomplish these activities. We make and expect to continue to make substantial capital expenditures in our business and operations for the development, production,

exploration and acquisition of oil and natural gas reserves. To date, we have financed capital expenditures primarily with cash flow from operations, the issuance of equity securities and borrowings under our bank and other credit facilities. Our cash flow from operations and access to capital are subject to a number of variables, including:

We cannot assure you that we will have sufficient resources to undertake exploration for and development, production and acquisition of oil and natural gas reserves, that our exploratory projects or other replacement activities will result in significant additional reserves or that we will have success drilling productive wells at low finding and development costs. Furthermore, although our revenues may increase if prevailing oil and natural gas prices increase significantly, our finding costs for additional reserves could also increase.

Shortage of rigs, equipment, supplies or personnel may restrict our operations.

The oil and natural gas industry is cyclical, and at the present time there is a shortage of drilling rigs, equipment, supplies and personnel. The costs and delivery times of rigs, equipment and supplies has increased as drilling activities have increased. In addition, demand for, and wage rates of, qualified drilling rig crews have risen with increases in the number of active rigs in service. In accordance with customary industry practice, we rely on independent third party service providers to provide most of the services necessary to drill new wells. Shortages of drilling rigs, equipment, supplies, personnel, trucking services, tubulars, fracing and completion services and production equipment could delay or restrict our exploration and development operations, which in turn could impair our financial condition and results of operations.

We rely on a few key employees whose absence or loss could disrupt our operations resulting in a loss of revenues.

Many key responsibilities within our business have been assigned to a small number of employees. The loss of their services, particularly the loss of Mike Liddell, our Chairman of the Board, James D. Palm, our Chief Executive Officer, Michael G. Moore, our Chief Financial Officer, or our two geophysicists, Stuart Maier and Randy Wilson, could disrupt our operations resulting in a loss of revenues. We do not have an employment contract with any of our executives, with the exception of Mr. Liddell, and our executives are not restricted from competing with us if they cease to be employed by us. Additionally, as a practical matter, any employment agreement we may enter into will not assure the retention of our employees. In addition, we do not maintain “key person” life insurance policies on any of our employees. As a result, we are not insured against any losses resulting from the death of our key employees.

Estimates of oil and natural gas reserves are uncertain and may vary substantially from actual production.

There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of expenditures, including many factors beyond our control. The reserve information set forth in this prospectus represents only estimates based on reports prepared by NSAI as of December 31, 2005. Petroleum engineering is not an exact science. Information relating to our proved oil and natural gas reserves is based upon engineering estimates. Estimates of economically recoverable oil and natural gas reserves and of future net cash flows necessarily depend upon a number of variable factors and assumptions, such as historical production from the area compared with production from other producing areas, future site restoration and abandonment costs, the assumed effects of regulations by governmental agencies and assumptions concerning future oil and natural gas prices, future operating costs, severance and excise taxes,

capital expenditures and workover and remedial costs, all of which may in fact vary considerably from actual results. For these reasons, estimates of the economically recoverable quantities of oil and natural gas attributable to any particular group of properties, classifications of such reserves based on risk of recovery and estimates of the future net cash flows expected therefrom prepared by different engineers or by the same engineers at different times may vary substantially. Actual production, revenues and expenditures with respect to our reserves will likely vary from estimates, and such variances may be material.

The present value of future net revenues from our proved reserves is not necessarily the same as the current market value of our estimated oil and natural gas reserves. We base the estimated discounted future net revenue from our proved reserves on prices and costs in effect on the day of estimate. However, actual future net revenues from our oil and natural gas properties also will be affected by factors such as:

The timing of both our production and our incurrence of costs in connection with the development and production of oil and natural gas properties will affect the timing of actual future net revenues from proved reserves, and thus their actual present value. In addition, the 10% discount factor we use when calculating discounted future net cash flows may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and natural gas industry in general. PV-10 is a non-GAAP measure because it excludes income tax effects. See “Business—Proved Oil and Natural Gas Reserves” for our definition of PV-10, a non-GAAP financial measure, and a reconciliation of our standardized measure of discounted future net cash flows to PV-10.

Substantially all of our producing properties are located in Louisiana, making us vulnerable to risks associated with operating in this region.

Our operations are concentrated in Louisiana. As a result, we may be disproportionately exposed to the impact of delays or interruptions of production from this region caused by hurricanes or other natural disasters, significant governmental regulation or lack of field infrastructure. Losses could occur for uninsured risks or in amounts in excess of existing insurance coverage. We cannot assure you that we will be able to maintain adequate insurance at rates we consider reasonable or that any particular types of coverage will be available. See “Summary—Our Company—Impact of Hurricanes” and “Business—West Cote Blanche Bay Field,” “—East Hackberry Field” and “—West Hackberry Field” for a discussion regarding the impact of Hurricane Rita and Hurricane Katrina.

Our identified drilling locations comprise an estimation of part of our future drilling plans over several years, making them susceptible to uncertainties that could materially alter the occurrence or timing of their drilling.

We have identified over 200 drilling locations on our core properties. These drilling locations represent a significant part of our growth strategy. Our ability to drill and develop these locations depends on a number of uncertainties, including the availability of capital, oil and natural gas prices, inclement weather, including hurricanes, costs and drilling results. Because of these uncertainties, we do not know if the numerous potential drilling locations we have identified will ever be drilled or if we will be able to produce oil or natural gas from these or any other potential drilling locations. As such, our actual drilling activities may materially differ from those presently identified, which could adversely affect our business.

Our operations are subject to all of the hazards and operating risks inherent in drilling for and production of oil and gas, including the risk of fire, explosions, blowouts, pipe failure, abnormally pressured formations and

environmental hazards such as oil spills, gas leaks, ruptures or discharges of toxic gases. The occurrence of any of these events could result in substantial losses to us due to injury or loss of life, severe damage to or destruction of property, natural resources and equipment, pollution or other environmental damage, clean-up responsibilities, regulatory investigation and penalties and suspension of operations. In accordance with customary industry practice, we historically have maintained insurance against some, but not all, of these risks. On April 1, 2006, our insurance expired and we are currently determining whether to renew our coverages. We cannot assure you that we will renew these coverages or, if we do, that such insurance will be adequate to cover any losses or liabilities we may suffer. We also cannot predict the continued availability of insurance, or its availability at premium levels that justify its purchase. In addition, we understand that insurance carriers are modifying or otherwise restricting insurance coverage or ceasing to provide certain types of insurance coverage in the Gulf Coast region. We may also be liable for environmental damage caused by previous owners of properties purchased by us, which liabilities would not be covered by insurance.

Our operations are subject to various governmental regulations which require compliance that can be burdensome and expensive.

Our oil and natural gas operations are subject to various federal, state and local governmental regulations that may be changed from time to time in response to economic and political conditions. Matters subject to regulation include discharge permits for drilling operations, drilling bonds, reports concerning operations, the spacing of wells, unitization and pooling of properties and taxation. From time to time, regulatory agencies have imposed price controls and limitations on production by restricting the rate of flow of oil and natural gas wells below actual production capacity to conserve supplies of oil and gas. In addition, the production, handling, storage, transportation and disposal of oil and gas, by-products thereof and other substances and materials produced or used in connection with oil and natural gas operations are subject to regulation under federal, state and local laws and regulations primarily relating to protection of human health and the environment. These laws and regulations have continually imposed increasingly strict requirements for water and air pollution control and solid waste management. Significant expenditures may be required to comply with governmental laws and regulations applicable to us. We believe the trend of more expansive and stricter environmental legislation and regulations will continue.

The oil and natural gas industry is intensely competitive, and we compete with other companies that have greater resources. Many of these companies not only explore for and produce oil and natural gas, but also carry on midstream and refining operations and market petroleum and other products on a regional, national or worldwide basis. These competitors may be better positioned to take advantage of industry opportunities and to withstand changes affecting the industry, such as fluctuations in oil and natural gas prices and production, the availability of alternative energy sources and the application of government regulation.

We depend upon two customers for the sale of most of our oil and natural gas production.

The availability of a ready market for any oil and/or natural gas we produced depends on numerous factors beyond the control of our management, including but not limited to the extent of domestic production and imports of oil, the proximity and capacity of gas pipelines, the availability of skilled labor, materials and equipment, the effect of state and federal regulation of oil and natural gas production and federal regulation of gas sold in interstate commerce. The oil and natural gas we produce in Louisiana is sold to purchasers who service the areas where our wells are located. We sell the majority of our oil to Shell Trading Company, or Shell. Shell takes custody of the oil at the outlet from our oil storage barge. Our production is being sold in accordance with the posted price for West Texas/New Mexico Intermediate crude plus Platt’s trade month average P+ value, plus or minus the Platt’s WII/LLS differential less $0.85 per Bbl for transportation. During 2005, we sold 99% of our oil production to Shell and 88% of our natural gas production to Chevron. During 2004, we sold 99% of our oil production to Shell and 68% and 21% of our natural gas production to Chevron and Apache Corporation, respectively. Our wells are not subject to any agreements that would prevent us from either selling our production on the spot market or

committing such gas to a long-term contract; however, there can be no assurance that we will continue to have ready access to suitable markets for our future oil and natural gas production.

Our method of accounting for oil and natural gas properties may result in impairment of asset value.

We use the full cost method of accounting for oil and natural gas operations. Accordingly, all costs, including nonproductive costs and certain general and administrative costs associated with acquisition, exploration and development of oil and natural gas properties, are capitalized. Net capitalized costs are limited to the estimated future net revenues, after income taxes, discounted at 10% per year, from proven oil and natural gas reserves and the cost of the properties not subject to amortization. Such capitalized costs, including the estimated future development costs and site remediation costs, if any, are depleted by an equivalent units-of-production method, converting gas to barrels at the ratio of six Mcf of gas to one barrel of oil.

Companies that use the full cost method of accounting for oil and gas properties are required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the oil and gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes or the cost center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted at 10% per annum, from proved reserves, based on unescalated year-end prices and costs, adjusted for any contract provisions or financial derivatives, if any, that hedge our and natural gas revenue, and excluding the estimated abandonment costs for properties with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if any, and (c) the lower of cost or market value of unproved properties included in the cost being amortized, less income tax effects related to differences between the book and tax basis of the oil and natural gas properties. If the net book value reduced by the related net deferred income tax liability exceeds the ceiling, an impairment or noncash writedown is required. A ceiling test impairment can give us a significant loss for a particular period. Once incurred, a write down of oil and natural gas properties is not reversible at a later date, even if oil or gas prices increase.

Our use of 2-D and 3-D seismic data is subject to interpretation and may not accurately identify the presence of oil and natural gas, which could adversely affect the results of our drilling operations.

Even when properly used and interpreted, 2-D and 3-D seismic data and visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. In addition, the use of 3-D seismic and other advanced technologies requires greater predrilling expenditures than traditional drilling strategies, and we could incur losses as a result of such expenditures. As a result, our drilling activities may not be successful or economical.

We have hedged and may continue to hedge a portion of our production, which may result in our making cash payments or prevent us from receiving the full benefit of increases in prices for oil and gas.

To reduce our exposure to short-term fluctuations in the price of oil and natural gas, we periodically enter into hedging arrangements. Our hedging arrangements currently in place for 2006 involve 45,000 barrels of oil per month at a price of $64.05 per barrel. Such hedging arrangements may expose us to risk of financial loss in certain circumstances, including instances where production is less than expected or oil prices increase. For example, under these arrangements the counterparty may require us to post cash collateral approximately equal to the difference between the agreed contract price of $64.05 per barrel and a defined market price multiplied by the remaining barrels of oil under the open contracts. As a result, significant increases in oil prices could adversely affect our financial position. In addition, our hedging arrangements may limit the benefit to us of increases in the price of oil.

We will be subject to the requirements of Section 404 of the Sarbanes-Oxley Act. If we are unable to timely comply with Section 404 or if the costs related to compliance are significant, our profitability, stock price and results of operations and financial condition could be materially adversely affected.

We will be required to comply with the provisions of Section 404 of the Sarbanes-Oxley Act of 2002 as of December 31, 2007. Section 404 requires that we document and test our internal control over financial reporting and issue management’s assessment of our internal control over financial reporting. This section also requires that our independent registered public accounting firm opine on those internal controls and management’s assessment of those controls. We will be required to evaluate our existing controls against the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. During the course of our ongoing evaluation and integration of the internal control over financial reporting, we may identify areas requiring improvement, and we may have to design enhanced processes and controls to address issues identified through this review.

We believe that the out-of-pocket costs, the diversion of management’s attention from running the day-to-day operations and operational changes caused by the need to comply with the requirements of Section 404 of the Sarbanes-Oxley Act could be significant. If the time and costs associated with such compliance exceed our current expectations, our results of operations could be adversely affected.

We cannot be certain at this time that we will be able to successfully complete the procedures, certification and attestation requirements of Section 404 or that we or our auditors will not identify material weaknesses in internal control over financial reporting. If we fail to comply with the requirements of Section 404 or if we or our auditors identify and report such material weakness, the accuracy and timeliness of the filing of our annual and quarterly reports may be materially adversely affected and could cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock. In addition, a material weakness in the effectiveness of our internal control over financial reporting could result in an increased chance of fraud and the loss of customers, reduce our ability to obtain financing and require additional expenditures to comply with these requirements, each of which could have a material adverse effect on our business, results of operations and financial condition.

If our quarterly revenues and operating results fluctuate significantly, the price of our common stock may be volatile.

Our revenues and operating results may in the future vary significantly from quarter to quarter. If our quarterly results fluctuate, it may cause our stock price to be volatile. We believe that a number of factors could cause these fluctuations, including:

Because of the factors listed above, among others, we believe that our quarterly revenues, expenses and operating results may vary significantly in the future and that period-to-period comparisons of our operating results are not necessarily meaningful. You should not rely on the results of one quarter as an indication of our future performance. It is also possible that in some future quarters, our operating results will fall below our expectations or the expectations of market analysts and investors. If we do not meet these expectations, the price of our common stock may decline significantly.

Our officers and directors together with our largest stockholder control a significant percentage of our common stock, and their interests may conflict with those of our other stockholders.

As of the date hereof, our executive officers and directors, in the aggregate, beneficially own approximately 5.6% of our outstanding common stock. Additionally, Charles E. Davidson beneficially owns approximately 61.0% of our outstanding common stock. Upon completion of this offering, our officers and directors, in the aggregate, will beneficially own 4.4%, and Mr. Davidson will beneficially own 43.5% of our outstanding common stock. As a result, these stockholders acting together are able to exercise significant influence over most matters requiring approval by our stockholders, including the election of directors and the approval of significant corporate transactions. Such a concentration of ownership may have the effect of delaying or preventing a change in control of us, including transactions in which stockholders might otherwise receive a premium for their shares over then current market prices.

We have incurred and will continue to incur increased costs as a result of being a public company.

As a result of being a public company, we have incurred and will continue to incur significant legal, accounting and other expenses. We have incurred and will continue to incur costs associated with our public company reporting requirements and costs associated with recently adopted corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, as well as new rules implemented by the SEC and the NASD. Prior to the consummation of this offering, we were considered to be a “controlled company” for the purposes of The Nasdaq National Market’s corporate governance requirements, and as a result were eligible for exemptions from provisions of these rules requiring that our board have a majority of independent directors, nominating and corporate governance and compensation committees composed entirely of independent directors and written charters addressing specified matters. Because we will cease to be a controlled company within the meaning of these rules upon consummation of this offering, we will be required to comply with these provisions after the specified transition periods. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We also expect these new rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officers. We are currently evaluating these new rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

Since February 28, 2006, our common stock has been quoted on The Nasdaq National Market under the symbol “GPOR.” Prior to that date, our common stock was traded on the NASD OTC Bulletin Board under the symbol “GPOR.OB.” There is a limited market for our shares. We cannot assure you that an active trading market will develop, or if it does, that it will be sustained.

We do not currently pay dividends on our common stock and do not anticipate doing so in the future.

We have paid no cash dividends on our common stock, and there can be no assurance that we will achieve sufficient earnings to pay cash dividends on our common stock in the future. We intend to retain any earnings to fund our operations. Therefore, we do not anticipate paying any cash dividends on our common stock in the foreseeable future. In addition, the terms of our credit agreement prohibit the payment of any dividends to the holders of our common stock.

As of December 31, 2005, we had a net operating loss, or NOL, carry forward of approximately $100.4 million for federal income tax purposes. Transfers of our stock in the future could result in an ownership

change. In such a case, our ability to use the NOLs generated through the ownership change date could be limited. In general, the amount of NOLs we could use for any tax year after the date of the ownership change would be limited to the value of our stock (as of the ownership change date) multiplied by the long-term tax-exempt rate.

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales may occur, could cause the market price of our common stock to decline. In addition, the sale of these shares could impair our ability to raise capital through the sale of common or preferred stock. As of April 18, 2006, we had 32,180,326 shares of common stock issued and outstanding.

In addition, some of our current stockholders may have “demand” and/or “piggyback” registration rights in connection with future offerings of our common stock. “Demand” rights enable the holders to demand that their shares be registered and may require us to file a registration statement under the Securities Act at our expense. “Piggyback” rights require that we provide notice to the relevant holders of our stock if we propose to register any of our securities under the Securities Act, and grant such holders the right to include their shares in the registration statement.

We could issue additional preferred stock which could be entitled to dividend, liquidation and other special rights and preferences not shared by holders of our common stock or which could have anti-takeover effects.

We are authorized to issue up to 5,000,000 shares of preferred stock, par value $0.01 per share. Shares of preferred stock may be issued from time to time in one or more series as our board of directors, by resolution or resolutions, may from time to time determine, each such series to be distinctively designated. The voting powers, preferences and relative, participating, optional and other special rights, and the qualifications, limitations or restrictions, if any, of each such series of preferred stock may differ from those of any and all other series of preferred stock at any time outstanding, and, subject to certain limitations of our certificate of incorporation and the Delaware General Corporation Law, or DGCL, our board of directors may fix or alter, by resolution or resolutions, the designation, number, voting powers, preferences and relative, participating, optional and other special rights, and qualifications, limitations and restrictions thereof, of each such series preferred stock. The issuance of any such preferred stock could materially adversely affect the rights of holders of our common stock and, therefore, could reduce the value of our common stock.

In addition, specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with, or sell our assets to, a third party. The ability of our board of directors to issue preferred stock could discourage, delay or prevent a takeover of us, thereby preserving control of the company by the current stockholders.

Provisions in our organizational documents could delay or prevent a change in control of our company, even if that change would be beneficial to our stockholders.

The existence of some provisions in our organizational documents could delay or prevent a change in control of our company, even if that change would be beneficial to our stockholders. Our certificate of incorporation and bylaws contain provisions that may make acquiring control of our company difficult. See “Description of Capital Stock—Anti-takeover Effects of Provisions of Our Certificate of Incorporation and Our Bylaws.”

This prospectus and the documents incorporated by reference herein include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. All statements other than statements of historical facts, included in this prospectus and the documents incorporated by reference herein that address activities, events or developments that we expect or anticipate will or may occur in the future, including such things as estimated future net revenues from oil and gas reserves and the present value thereof, future capital expenditures (including the amount and nature thereof), business strategy and measures to implement strategy, competitive strength, goals, expansion and growth of our business and operations, plans, references to future success, reference to intentions as to future matters and other such matters are forward-looking statements. These statements are based on certain assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate in the circumstances. However, whether actual results and developments will conform with our expectations and predictions is subject to a number of risks and uncertainties, general economic, market or business conditions; the opportunities (or lack thereof) that may be presented to and pursued by us; competitive actions by other oil and natural gas companies; changes in laws or regulations; hurricanes and other natural disasters and other factors, many of which are beyond our control. Consequently, all of the forward-looking statements made in this prospectus, and the documents incorporated by reference in this prospectus, are qualified by these cautionary statements and we cannot assure you that the actual results or developments anticipated by us will be realized or, even if realized, that they will have the expected consequences to or effects on us, our business or operations. We have no intention, and disclaim any obligation, to update or revise any forward looking statements, whether as a result of new information, future results or otherwise.

We will not receive any proceeds from the sale of shares or our common stock by the selling stockholders.

We have granted the underwriters an option to purchase up to an additional 907,500 shares of common stock from us to cover over-allotments, if any. Assuming the underwriters exercise their over-allotment option in full, the net proceeds from our sale of these shares of common stock will be approximately $12.1 million, based on an assumed public offering price of $14.72 per share (the last sale price of our common stock as reported on The Nasdaq National Market on April 18, 2006) and after deducting estimated underwriting discounts and commissions and estimated offering expenses. If the underwriters exercise their over-allotment option, we intend to use the net proceeds to repay outstanding borrowings under our credit facility with Bank of America. Our credit facility provides for a $30.0 million revolver subject to a current borrowing base limitation of $23.0 million. On April 18, 2006, $19.5 million was outstanding under this facility. The credit facility has a term of three years and all principal amounts of revolving loans outstanding under the credit facility, together with all accrued and unpaid interest and fees, will be due and payable on March 11, 2008. Amounts borrowed against the credit facility bear interest at the Bank of America prime rate plus 0.25% (7.5% at December 31, 2005). Our obligations under the credit facility are collateralized by a lien on substantially all of our Louisiana based oil and natural gas assets. The outstanding borrowings under our credit facility were used for general corporate purposes.

The following table sets forth our cash and cash equivalents and capitalization as of December 31, 2005:

You should read this table in conjunction with the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and related notes which are incorporated by reference in this prospectus.

On April 18, 2006, the last reported sale price of our common stock on The Nasdaq National Market was $14.72 and there were 32,180,326 shares of our common stock outstanding and approximately 400 stockholders of record.

We have never paid dividends on our common stock. We currently intend to retain all earnings to fund our operations. Therefore, we do not intend to pay any cash dividends on the common stock in the foreseeable future. In addition, the terms of our credit facility prohibits the payment of any dividends to the holders of our common stock.

The following table sets forth our selected historical financial data as of and for each of the years indicated. We derived the selected historical financial data as of and for each of the years ended 2005, 2004 and 2003 from our historical audited financial statements. You should review this information together with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and historical financial statements and related notes incorporated by reference in this prospectus.

We are an independent oil and natural gas exploration and production company with properties located along the Louisiana Gulf Coast. Our operations are concentrated in two fields: WCBB and East Hackberry. As of December 31, 2005, we had 23.2 MMboe of proved reserves, of which 84% was oil, with a present value of estimated future net revenues, discounted at 10%, or PV-10, of approximately $456.9 million and associated standardized measure of discounted future net cash flows of approximately $369.8 million. See “—Proved Oil and Natural Gas Reserves” for our definition of PV-10, a non-GAAP financial measure, and a reconciliation of our standardized measure of discounted future net cash flows to PV-10. Our 2005 production was 84% oil.

We seek to achieve reserve and production growth and increase our cash flow through our annual drilling programs. In 2005, we drilled 17 wells and recompleted 11 existing wells in our WCBB field for a total estimated cost of $21.1 million. Of our 17 new wells, nine were completed as producing wells, seven were waiting to be completed at year end (one of which will be side-tracked in 2006 to test deeper zones) and one was a dry hole. During 2006, we intend to drill 22 wells and recomplete 18 existing wells at our WCBB field for an estimated aggregate cost of $33.2 million. As of April 18, 2006, we had drilled ten new wells of which eight are awaiting completion and two were dry holes. During 2005, we completed a 3-D seismic program at our East Hackberry field to enhance our drilling program at that field and we currently intend to drill up to six wells in 2006 for an estimated aggregate cost of $13.3 million.

We own interests in producing oil and natural gas properties located along the Louisiana Gulf Coast. The following table presents certain information as of December 31, 2005 reflecting our net interest in our principal producing oil and natural gas properties in Louisiana.

The WCBB field lies approximately five miles off the coast of Louisiana, primarily in St. Mary Parish, in a shallow bay with water depths averaging eight to ten feet. Currently, we own a 100% working interest (79.4% NRI), and are the operator, in depths above the base of the 13900 Sand which is located at 11,320 feet. In addition, we own a 40.4% non-operated working interest (30.0% NRI) in depths below the base of the 13900 Sand, which is operated by Chevron Corporation. Our leasehold interests at WCBB cover a portion of Louisiana State Lease 340 and contain 5,668 gross acres.

Texaco, now Chevron Corporation, drilled the discovery well in this field in 1940 based on a seismic and gravitational anomaly. WCBB was subsequently developed on an even 160-acre pattern for much of the remainder of the decade. Developmental drilling continued and reached its peak in the 1970s when over 300 wells were drilled in the field. Of the 846 wells drilled as of December 31, 2005, 766 were completed as producing wells. As a result, the field has a historic success rate of 90% for all wells drilled. As of December 31, 2005, estimated field cumulative gross production was 193 MMbo and 234 Bcf of gas.

Of the 846 wells drilled in WCBB as of December 31, 2005, 57 were producing prior to being shut-in beginning on September 21, 2005 in preparation for Hurricane Rita, nine were drilled after Hurricane Rita but not completed by year end, 172 were shut-in, 30 were producing intermittently and five were being used as salt water disposal wells. The other 573 wells have been plugged and abandoned. During the period January 1, 2005 through September 21, 2005, our net daily production at WCBB averaged 2,125 barrels of oil, 2,132 Mcf of gas and 11,470 barrels of water.

In 1991, Texaco conducted a 70 square mile 3-D seismic survey. In 1993, an undershoot survey around the crest and production facilities was completed. We own the rights to the seismic data. In December 1999, we completed the reprocessing of the seismic data which our technical staff used to identify and develop prospects in areas of the field that would have otherwise remained obscure. During the first half of 2005, we again reprocessed the seismic data using the most recent advances in seismic data processing.

From our acquisition of WCBB in 1997 through December 31, 2005, we drilled 62 new wells, seven of which were dry holes, for an 89% success rate. These wells produced 2,749 gross Mboe through December 31, 2005. We have also recompleted 57 existing wells resulting in 44 producing wells. These recompleted wells produced 1,193 gross Mboe through December 31, 2005.

WCBB overlies one of the largest salt dome structures on the Gulf Coast. The field is characterized by a piercement salt dome, which created traps from the Pleistocene through the Miocene formations. The relative movements affected deposition and created a complex system of fault traps. The compensating fault sets generally trend northwest to southeast and are intersected by sets having a major radial component. Later-stage movement caused extension over the dome and a large graben system (a downthrown area bounded by normal faults) was formed.

There are over 100 distinct sandstone reservoirs recognized throughout most of the field, and nearly 200 major and minor discrete intervals have been tested. Within the 846 wellbores that had been drilled in the field as of December 31, 2005, over 4,000 potential zones have been penetrated. These sands are highly porous and permeable reservoirs primarily with a strong water drive.

WCBB is a structurally and stratigraphically complex field. All of the PUD locations at WCBB are adjacent to faults and abut at least one fault. Our drilling programs are designed to penetrate each PUD trap with a new wellbore in a structurally optimum position, usually very close to the fault seal. The majority of these wells have been, and new wells drilled in connection with our drilling programs will be, directionally drilled using steering tools and downhole motors. The tolerance for error in getting near the fault is low, so the complex faulting does introduce the risk of crossing the fault before encountering the zone of interest, which could result in part or all of the zone being absent in the borehole. This, in turn, can result in lower than expected or no reserves for that zone. The new wellbores eliminate the mechanical risk associated with trying to produce the zone from an old existing wellbore, while the wellbore locations are selected in an effort to more efficiently drain each reservoir. The vast majority of the PUD targets are up-dip offsets to wells that produced from a sub-optimal position within a particular zone. Our inventory of prospects includes approximately 120 PUD wells. The drilling schedule used in the reserve report anticipates that all of those wells will be drilled by 2015.

We own and operate a production facility at WCBB that includes four production tank batteries and is equipped with hydrocarbon separation equipment, four natural gas compressor platforms, a dehydration unit and a salt water disposal system. We sustained minimal damage to our facilities at WCBB from Hurricane Katrina which came onshore on August 29, 2005. Our WCBB facilities were shut-in and evacuated for precautionary reasons for only four days. On September 24, 2005, however, the tidal surge from Hurricane Rita caused damage to our WCBB facilities and all of our active WCBB wells were shut-in. Our main tank batteries, which handled approximately 70% of our production before Hurricane Rita, and the gas sales line are now operational, and we anticipate that the balance of our production facilities at WCBB will be brought on line in the second and third quarters of 2006. We began returning WCBB wells to production on February 5, 2006, and as of April 18, 2006, 27 of the 57 active wells in the field prior to Hurricane Rita had been returned to production on an intermittent basis. We continue to reactivate our remaining shut-in WCBB wells and are in the process of completing 15 wells that have been drilled after Hurricane Rita but not completed due to the damage to our facilities caused by that storm. We expect that all of these wells will begin producing during the second quarter of 2006. We have an insurance program in place that we believe will adequately cover damage to our platform and facilities at WCBB. In addition, business interruption insurance has helped mitigate the financial impact of Hurricane Rita on our WCBB operations. Once fully operational, we believe our facilities will have capacity in excess of our current and anticipated production volumes.

In 2005, we drilled 17 wells and recompleted 11 existing wells at WCBB. Of these 17 new wells, nine were completed as producers, seven were drilled subsequent to Hurricane Rita and have not yet been completed (including one that will be side-tracked in 2006 to test deeper zones) and one was a dry hole. We anticipate drilling 22 wells and recompleting 18 wells at WCBB during 2006. As of April 18, 2006, we had drilled ten new wells and production casing has been run on seven of these wells, bringing to 15 the number of wells that have been drilled but not yet been completed due to the effects of Hurricane Rita. The 15 wells that are now in the process of being completed are expected to begin producing in the second quarter of 2006. The remaining two wells drilled in 2006 were dry holes.

The ten wells we have drilled at WCBB to date in 2006 include three deep wells, three intermediate depth wells and four shallow wells. The deep wells, with total depths ranging from 8,850 to 9,400 feet, have approximately 373 feet of apparent net pay. The intermediate wells, with total depths ranging from 5,000 to 7,500 feet, have approximately 188 feet of apparent net pay. Two of the shallow wells, at depths of less than 3,000 feet, have 40 feet of apparent net pay. Two additional shallow wells were unsuccessful, including one exploratory well that was drilled to satisfy our drilling commitment to hold the non-productive portions of WCBB.

In the second quarter of 2006, we anticipate drilling a 12,000 foot wildcat test well targeting the higher-pressure gas zones in the field for an anticipated well cost of approximately $5.5 million. The cost of this wildcat well is approximately four times the cost of a typical well drilled to 9,500 feet, and has more geologic risk.

However, we believe the additional geological risk is warranted by the higher reserve and production potential of the wildcat test. We have also identified other deeper wildcat gas test wells on the WCBB salt dome acreage, as well as undrilled conventional depth fault blocks. We expect to test these exploratory prospects in 2007 and thereafter based on our drilling results and available cash flows.

On September 20, 2005, prior to Hurricane Rita, 57 wells, including nine productive wells we drilled in 2005, were producing and total net production at WCBB on that date was 2,204 Boe, 97% of which was from oil and 3% of which was from natural gas. During the period March 20, 2006 through March 30, 2006, total net production at WCBB from 27 of the 57 active wells that were shut-in in preparation for Hurricane Rita ranged from 1,754 Boe to 3,032 Boe per day. Aggregate net production from WCBB during the first quarter of 2006 was 59.1 Mboe. We expect our WCBB production to increase substantially in the second quarter of 2006 as the remaining wells shut-in for Hurricane Rita are returned to production and our 15 new wells drilled after the hurricane, together with additional wells that are now being drilled as part of our 2006 drilling program, are completed and brought on-line.

The East Hackberry field is located along the western shore of Lake Calcasieu in Cameron Parish, Louisiana, approximately 80 miles west of Lafayette and 15 miles inland from the Gulf of Mexico. We own a 100% working interest (approximately 79% average NRI) in certain producing oil and natural gas properties situated in the East Hackberry field. The interest includes two separate lease blocks, the Erwin Heirs Block, which is located on land, and the adjacent State Lease 50 Block, which is located primarily in the shallow waters of Lake Calcasieu. The two lease blocks together contain 3,147 acres.

The East Hackberry field was discovered in 1926 by Gulf Oil Company, now Chevron Corporation, by a gravitational anomaly survey. The massive shallow salt stock presented an easily recognizable gravity anomaly indicating a productive field. Initial production began in 1927 and has continued to the present. The estimated cumulative oil and condensate production through 2005 was over 49 MMbo and 41 Bcf of casinghead gas production. There have been a total of 170 wells drilled on our portion of the field. As of December 31, 2005, six wells had daily production, 84 were shut-in and two had been converted to salt water disposal wells. The remaining 78 wells had been plugged and abandoned.

The Hackberry salt ridge is a major salt intrusive feature, elliptical in shape as opposed to a classic “dome,” divided into east and west field entities by a saddle. Structurally, our East Hackberry acreage is located on the eastern end of the Hackberry salt ridge. There are over 30 pay zones at this field. The salt intrusion formed a series of structurally complex and steeply dipping fault blocks in the Lower Miocene and Oligocene age rocks. These fault blocks serve as traps for hydrocarbon accumulation. Our wells currently produce from perforations found between 5,100 and 12,200 feet.

We have land-based production and processing facilities located at the East Hackberry field. The facilities include dehydrating units and disposal pumps. We also have a field office that serves both the East and West Hackberry fields.

During 2005, we completed a proprietary 42 square mile 3-D seismic survey at East Hackberry for a total cost in 2004 and 2005 of approximately $5.0 million. Given that previous drilling activities at the East Hackberry field were undertaken without the benefit of modern seismic information, we believe that the newly acquired 3-D seismic data will enhance our probability of drilling success. We are evaluating the newly processed 3-D seismic data to identify additional drilling locations. We currently intend to drill six wells during 2006 to measured depths of approximately 13,000 feet using directional drilling techniques. The 3-D seismic data also suggests the possibility of deep gas production and, as a result, we intend to drill a deep wildcat well during 2007 for a total anticipated well cost of approximately $4.0 million. If productive, multiple offset locations could be drilled.

Prior to shutting-in our 11 producing East Hackberry wells on September 20, 2005 in preparation for Hurricane Rita, aggregate net production was approximately 299 Boe per day. Production was re-established from six of these wells in November 2005, and during the period March 20, 2006 through March 30, 2006, aggregate net production from these wells ranged from approximately 181 Boe to 219 Boe per day. Due to damage to certain of our production facilities caused by Hurricane Rita, five wells in our State Lease 50 Block remain shut-in. Prior to being shut-in, these five wells in the field had aggregate production of approximately 50 Boe per day with a limited amount of gas. We plan on replacing or upgrading certain of our East Hackberry facilities in connection with our 2006 drilling program and intend to put the five remaining shut-in wells back on line when these facilities are completed. Aggregate net production from the East Hackberry field during the first quarter of 2006 was 14.6 Mboe.

The West Hackberry field is located on land and is five miles West of Lake Calcasieu in Cameron Parish, Louisiana, approximately 85 miles west of Lafayette and 15 miles inland from the Gulf of Mexico. We own a 100% working interest (approximately 87.5% NRI) in 592 acres within the West Hackberry field. Our leases at West Hackberry are located within two miles of one of the United States Department of Energy’s Strategic Petroleum Reserves.

The first discovery well at West Hackberry was drilled in 1938 and the field was developed by Superior Oil Company, now ExxonMobil Corporation, between 1938 and 1988. The estimated cumulative oil and condensate production through 2005 was 18.4 MMbo and 12.9 Bcf of natural gas. There have been 36 wells drilled to date on our portion of West Hackberry. Currently, three are producing, 24 are shut-in and one has been converted to a saltwater disposal well. The remaining eight wells have been plugged and abandoned. During the period March 20, 2006 through March 30, 2006, aggregate net production from the wells ranged from 72 Boe to 83 Boe per day.

Structurally, our West Hackberry acreage is located on the western end of the Hackberry salt ridge. There are over 30 pay zones at this field. West Hackberry consists of a series of fault-bounded traps in the Oligocene-age Vincent and Keough sands associated with the Hackberry salt ridge. Recoveries from these thick, porous, water-drive reservoirs have resulted in per well cumulative production of almost 700 Mboe.

We have land-based production and processing facilities located at the West Hackberry field and maintain a field office that serves both the East and West Hackberry fields.

Louisiana. In addition to our interests in the WCBB, East Hackberry and West Hackberry fields, we also own working interests and an overriding royalty interest in various fields in Louisiana as described in the following table:

Thailand. During March 2005, we purchased a 23.5% ownership interest in Tatex Thailand II, LLC, or Tatex, at a cost of $2,400,000. The remaining interests in Tatex are owned by other entities controlled by Wexford Capital LLC, or Wexford, an affiliate of ours. Tatex holds approximately 8.5% of the outstanding shares of APICO, LLC, or APICO, an international oil and gas exploration company, and our investment is accounted for on the cost method. APICO has a reserve base located in Southeast Asia through its ownership interests in concessions covering 3 million acres. Our interest in Tatex includes proved reserves, net to our interest, of 3.36 Bcf of natural gas and 10,082 barrels of oil at August 1, 2005, the latest date that reserve information is available to us. These reserves are not included in our December 31, 2005 reserve report.

Williston Basin. During 2005, we purchased a 20% ownership interest in Windsor Bakken, LLC, or Bakken. The remaining interests in Bakken are owned by other entities controlled by Wexford, an affiliate of ours. As of December 31, 2005, Bakken had acquired leases covering approximately 83,300 gross and 41,600 net acres, all of which is undeveloped, in the Williston Basin located in western North Dakota and eastern Montana. The Williston Basin has production from 11 major geologic horizons that range in depth from 1,000 to over 14,000 feet, with our current zones of interest lying at depths ranging from 9,000 to 12,000 feet. Activities in this basin are expected to include both exploration and development drilling programs to different horizons including the Bakken shale. It is currently contemplated that Bakken will contribute all of its assets to Windsor Energy Resources, Inc., or Windsor Energy, in connection with Windsor Energy’s proposed initial public offering. We would receive an indirect equity interest in Windsor Energy as a result of that contribution. Windsor Energy is beneficially owned by Wexford and is an affiliate of ours.

Marquiss Field. In February 2005, we acquired our interest in the Marquiss field, an approximately 9,500 net acre coalbed methane play in Campbell County, Wyoming, for $375,000. As of December 31, 2005, the Marquiss field included a total of 162 wells, of which 105 were producing and 57 were shut-in. The effective date of the sale was December 1, 2004. The wells produce from multiple horizons with additional upside potential from deeper coals and operational efficiencies. The Marquiss field contained proved gas reserves, net to our interest, of 212,548 Mcf at December 31, 2005. These reserves are not included in our December 31, 2005 reserve report. We plan to contribute these properties to Windsor Energy, an affiliate of our company, in connection with its initial public offering in exchange for common stock of Windsor Energy.

The availability of a ready market for any oil and/or natural gas we produce depends on numerous factors beyond the control of our management, including but not limited to the extent of domestic production and imports of oil, the proximity and capacity of gas pipelines, the availability of skilled labor, materials and equipment, the effect of state and federal regulation of oil and natural gas production and federal regulation of gas sold in interstate commerce. The oil and natural gas we produce in Louisiana is sold to purchasers who service the areas where our wells are located. We sell the majority of our oil to Shell Trading Company, or Shell. Shell takes custody of the oil at the outlet from our oil storage barge. Our production is being sold in accordance with the posted price for West Texas/New Mexico Intermediate crude plus Platt’s trade month average P+ value, plus or minus the Platt’s WII/LLS differential less $0.85 per Bbl for transportation. During 2005, we sold 99% of our oil production to Shell and 88% of our natural gas production to Chevron. During 2004, we sold 99% of our oil production to Shell and 68% and 21% of our natural gas production to Chevron and Apache Corporation, respectively. Our wells are not subject to any agreements that would prevent us from either selling our production on the spot market or committing such natural gas to a long-term contract; however, there can be no assurance that we will continue to have ready access to suitable markets for our future oil and natural gas production.

Production from our Marquiss field in Wyoming is gathered in the field and delivered to Western Gas Resources at two gas sales meters located in our field. We are paid based on a Gas Daily CIG index net of various deductions for gathering, quality and fuel for compression.

Oil and natural gas prices can be extremely volatile and are subject to substantial seasonal, political and other fluctuations. The prices at which the oil and natural gas we produce may be sold is uncertain and it is possible that under some market conditions the production and sale of oil and natural gas from some or all of our properties may not be economical. Because of all of the factors influencing the price of oil and natural gas, it is impossible to accurately predict future prices.

We established an oil price-hedging program in August 2005 to reduce our exposure to unfavorable changes in oil prices, which are subject to significant and often volatile fluctuation, by taking receive-fixed positions in price swap contracts. We pay the counterparty the excess of the oil market price over the fixed price and will receive the excess of the fixed price over the market price as defined in each contract. These contracts allow us to predict with greater certainty the effective oil prices to be received for hedged production and benefit operating cash flows and earnings when market prices are less than the fixed prices provided in the contracts. However, we will not benefit from market prices that are higher than the fixed prices in the contracts for hedged production. For the year ended December 31, 2005, fixed-price contracts hedged 8.7% of our oil production. As of December 31, 2005, fixed-price contracts were in place to hedge 540,000 barrels of estimated future production during 2006.

Oil and natural gas operations are subject to various types of regulation by state and federal agencies. Legislation affecting the oil and natural gas industry is under constant review for amendment or expansion. Also, numerous departments and agencies, both federal and state, are authorized by statute to issue rules and regulations binding on the oil and natural gas industry and its individual members, some of which carry substantial penalties for failure to comply. The regulatory burden on the oil and natural gas industry increases our cost of doing business and, consequently, affects our profitability.

We own interests in a number of producing oil and natural gas properties located along the Louisiana Gulf Coast and Wyoming. These states regulate the production and sale of oil and natural gas, including requirements for obtaining drilling permits, the method of developing new fields and the spacing and operation of wells. In addition, regulations governing conservation matters aimed at preventing the waste of oil and natural gas resources could affect the rate of production and may include maximum daily production allowables for wells on a market demand or conservation basis.

Our oil and natural gas exploration, development and production operations are subject to stringent federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. Numerous governmental agencies, such as the U.S. Environmental Protection Agency, or EPA, issue regulations to implement and enforce such laws, which often require difficult and costly compliance measures that carry substantial administrative, civil and criminal penalties or may result in injunctive relief for failure to comply. These laws and regulations may require the acquisition of a permit before drilling commences, restrict the types, quantities and concentrations of various substances that can be released into the environment in connection with drilling and production activities, limit or prohibit construction or drilling activities on certain lands lying within wilderness, wetlands, ecologically sensitive and other protected areas, require remedial action to prevent pollution from former operations, such as plugging abandoned wells or closing pits, and impose substantial liabilities for pollution resulting from our operations. Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent and costly waste handling, storage, transport, disposal, cleanup or permitting requirements could materially adversely affect our operations and financial position, as well as the oil and natural gas industry in general. Our management believes that we are in substantial compliance with current applicable environmental laws and regulations and we have not experienced any material adverse effect from compliance with these environmental requirements; this trend, however, may not continue in the future.

Waste Handling. The Resource Conservation and Recovery Act, or RCRA, and comparable state statutes, affect oil and natural gas exploration and production activities by imposing regulations on the generation, transportation, treatment, storage, disposal and cleanup of “hazardous wastes” and on the disposal of non-hazardous wastes. With federal approval, the individual states administer some or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent requirements. Although wastes associated with the exploration, development and production of crude oil and natural gas are exempt from regulation as hazardous wastes under RCRA, such wastes may constitute “solid wastes” that are subject to the less stringent requirements of non-hazardous waste provisions. However, there can be no assurance that the EPA or the state or local governments will not adopt more stringent requirements for the handling of non-hazardous wastes or categorize some non-hazardous wastes as hazardous for future regulation. Indeed, legislation has been proposed from time to time to re-categorize certain oil and natural gas exploration and production wastes as “hazardous wastes.”

Administrative, civil and criminal penalties can be imposed for failure to comply with waste handling requirements. We believe that we are in substantial compliance with the requirements of RCRA and related state and local laws and regulations, and that we hold all necessary and up-to-date permits, registrations and other authorizations to the extent that our operations require them under such laws and regulations. Although we do not believe that the current costs of managing our wastes as they are presently classified to be significant, any legislative or regulatory reclassification of oil and natural gas exploration and production wastes could increase our costs to manage and dispose of such wastes.

Comprehensive Environmental Response, Compensation and Liability Act. The Comprehensive Environmental Response, Compensation and Liability Act, also known as CERCLA or the “Superfund” law, and comparable state statutes, generally impose joint and several liability, without regard to fault or legality of conduct, on classes of persons who are considered to be responsible for the release of a “hazardous substance” into the environment. These persons include the current owner or operator of a contaminated facility, a former owner or operator of the facility at the time of contamination and those persons that disposed or arranged for the disposal of the hazardous substance. Under CERCLA, such persons may be subject to strict joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. In addition, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. In the course of our operations, we use, and previous operators of our properties may have used, materials, that, if released, would be subject to CERCLA. Therefore, governmental agencies or third parties may seek to hold us responsible under CERCLA for all or part of the costs to clean up sites at which such “hazardous substances” have been deposited.

Water Discharges. The Federal Water Pollution Control Act of 1972, as amended, also known as the Clean Water Act, and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants, including produced waters and other gas and oil wastes, into state waters or waters of the United States. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA or the state. These proscriptions also prohibit certain activity in wetlands unless authorized by a permit issued by the U.S. Army Corps of Engineers. The Clean Water Act and the Oil Pollution Act of 1990 (OPA) require facilities that store or otherwise handle oil in excess of specified quantities to prepare and implement spill prevention, control and countermeasure plans and facility response plans relating to possible discharges of oil to surface water. Costs may be associated with the treatment of wastewater or developing and implementing required plans. We believe that we have obtained or applied for all permits required under the Clean Water Act. Sanctions for failure to comply with Clean Water Act requirement include administrative, civil and criminal penalties, as well as injunctive relief.

Air Emissions. The federal Clean Air Act, and associated state laws and regulations, regulate emissions of various air pollutants through the issuance of permits and the imposition of other requirements. In addition, the EPA has developed, and continues to develop, stringent regulations governing emissions of toxic air pollutants at specified sources. Some of our new facilities will be required to obtain permits before work can begin, permits may be required for our facilities’ operations, and existing facilities may be required to incur capital costs to remain in compliance. These regulations may increase the costs of compliance for some facilities we own or operate, and federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with air permits or other requirements of the federal Clean Air Act and associated state laws and regulations. We believe that we are in substantial compliance with all air emissions regulations and that we hold all necessary and valid construction and operating permits for our operations. Obtaining permits has the potential to delay the development of oil and natural gas projects.

Coastal Coordination. Various state and federal programs regulate the conservation and development of coastal resources. The federal Coastal Zone Management Act, CZMA, was passed in 1972 to preserve and, where possible, restore the natural resources of the Nation’s coastal zone. The CZMA provides for federal grants for state management programs that regulate land use, water use and coastal development. In Louisiana, state legislation enacted in 1978 established the Louisiana Coastal Zone Management Program, LCZMP, to protect, develop and, where feasible, restore and enhance coastal resources of the state. Under the LCZMP, coastal use permits are required for certain activities in the coastal zone, even if the activity only partially infringes on the coastal zone. The Coastal Management Division of Louisiana’s Department of Natural Resources administers the coastal use permit program which applies in the coastal areas of 18 of Louisiana’s 64 parishes. Activities requiring such a permit include, among other things, projects involving the use of state lands and water bottoms, dredge or fill activities that intersect with more than one body of water, mineral activities, including the exploration and production of oil and gas, and pipelines for the gathering, transportation or transmission of oil, gas and other minerals. General permits, which entail a reduced administrative burden, are available for a number of routine oil and gas activities. The LCZMP and its requirement to obtain coastal use permits may result in additional permitting requirements and associated time constraints for our projects.

OSHA. We are subject to the requirements of the federal Occupational Safety and Health Act, OSHA, and comparable state statutes. The OSHA Hazard Communications Standard, the EPA Community Right to Know regulations under Title III of CERCLA, and similar state statutes require us to organize and/or disclose information about hazardous materials used or produced in our operations. We believe we are in substantial compliance with the applicable requirements.

Our operations are subject to all of the risks normally incident to the production of oil and natural gas, including blowouts, cratering, pipe failure, casing collapse, oil spills and fires, each of which could result in severe damage to or destruction of oil and natural gas wells, production facilities or other property, or injury to persons. The energy business is also subject to environmental hazards, such as oil spills, gas leaks, and ruptures

and discharge of toxic substances or gases that could expose us to substantial liability due to pollution and other environmental damage. Although we maintain insurance coverage considered to be customary in the industry for a company of our size, we are not fully insured against certain of these risks, either because such insurance is not available or because of high premium costs. The occurrence of a significant event that is not fully insured against could have a material adverse effect on our financial position.

We own an approximately 28,500 square foot office building in Oklahoma City, Oklahoma that serves as our corporate headquarters. We lease a portion of this office space to certain of our affiliates. We also own an approximately 12,500 square foot building in Lafayette, Louisiana that is used as our Louisiana headquarters. This building contains approximately 6,200 square feet of finished office area and 6,300 square feet of warehouse area.

As of April 15, 2006, we had 83 employees. Certain of our employees perform management and administrative services for affiliated companies. We are reimbursed by these affiliates for the salaries and benefits of these individuals based on the estimated time they spent working for those affiliates. In addition, we receive 100% of the Council of Petroleum Accountants Societies (COPAS) overhead charges billed to these affiliated companies. For the years ended December 31, 2005 and 2004, expenses reimbursed to us under these arrangements were $6,232,000 and $2,146,000, respectively, and are reflected as a reduction in our general and administrative expenses. A Louisiana well servicing company serves as contract operator of WCBB and the Hackberry fields and provides all necessary field personnel.

The oil and natural gas reserve information set forth below represents estimates as prepared by the independent engineering firm of NSAI. Reserve engineering is a subjective process of estimating volumes of economically recoverable oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation. As a result, the estimates of different engineers often vary. In addition, the results of drilling, testing and production may justify revisions of such estimates. Accordingly, reserve estimates often differ from the quantities of oil and natural gas that are ultimately recovered. Estimates of economically recoverable oil and natural gas and of future net revenues are based on a number of variables and assumptions, all of which may vary from actual results, including geologic interpretation, prices, and future production rates and costs. See “Risk Factors” contained elsewhere in this prospectus. We have not filed any estimates of total, proved net oil or gas reserves with any federal authority or agency other than the SEC since the beginning of our last fiscal year.

The following table sets forth estimates of our proved oil and natural gas reserves at December 31, 2005 and 2004, as estimated by NSAI.

The above table does not include (a) proved reserves, net to our interest in Tatex, of 3.36 Bcf of gas and 10,082 barrels of oil at August 1, 2005 or (b) proved reserves attributable to our Marquiss field of 212,584 Mcf of gas at December 31, 2005. For further discussion of our interests in Tatex and the Marquiss field, see “Business—Additional Properties.”

Proved developed reserves are proved reserves that can be expected to be recovered from existing wells with existing equipment and operating methods. Proved undeveloped reserves are proved reserves that are expected to be recovered from new wells drilled to known reservoirs on undrilled acreage for which the existence and recoverability of such reserves can be estimated with reasonable certainty, or from existing wells on which a relatively major expenditure is required to establish production.

Total proved reserves decreased 1,593 Mboe to 23,172 Mboe at December 31, 2005 from 24,765 at December 31, 2004. This decrease in reserves is mainly attributable to reserve revisions and reductions related to our 2005 production. Further, a significant portion of the reserves that were categorized as proved developed producing at December 31, 2004 have been recategorized as proved developed non-producing shut-in or proved undeveloped as a result of the damage caused by Hurricane Rita in September 2005.

The following table presents our production volumes and average prices received during the periods indicated:

Also includes financial hedge contracts with a mark-to-market value of approximately $50,000 total for the months of September—December 2005.

Excluding the effect of the fixed price contracts, the average oil price for 2005 would have been $56.17 per Bbl and $52.99 per Bbl oil equivalent price. Excluding the effect of the fixed price contracts, the average oil price for 2004 would have been $42.72 per Bbl and $41.88 per Bbl oil equivalent price. Excluding the effect of the fixed price contracts, the average oil price for 2003 would have been $32.38 per Bbl and $32.08 per Bbl oil equivalent price.

The following table presents our total gross and net productive wells, expressed separately for oil and gas, and the total gross and net developed acres as of December 31, 2005:

The following table sets forth information with respect to wells completed during the periods indicated. The information should not be considered indicative of future performance, nor should it be assumed that there is necessarily any correlation between the number of productive wells drilled, quantities of reserves found or economic value. Productive wells are those that are found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of the production exceed production expenses and taxes.

It is customary in the oil and natural gas industry to make only a cursory review of title to undeveloped oil and natural gas leases at the time they are acquired and to obtain more extensive title examinations when acquiring producing properties. In future acquisitions, we will conduct title examinations on material portions of such properties in a manner generally consistent with industry practice. Certain of our oil and natural gas properties may be subject to title defects, encumbrances, easements, servitudes or other restrictions, none of which, in management’s opinion, will in the aggregate materially restrict our operations.

We have been named as a defendant in various lawsuits related to our business. The ultimate resolution of these matters is not expected to have a material adverse effect on our financial condition or results of operations.

Audit Committee. The audit committee oversees our accounting and financial reporting processes and the audits of our financial statements. In that regard, the audit committee assists our board of directors in monitoring (1) our accounting, auditing and financial reporting processes generally, including the qualifications, independence and performance of the independent auditor, (2) the integrity of our financial statements, (3) our systems of internal control regarding finance and accounting and (4) our compliance with legal and regulatory requirements.

The audit committee is composed of David L. Houston, Robert E. Brooks and Phillip G. Lancaster, all of whom are non-employee directors. All of the members of the audit committee are financially literate and Mr. Houston serves as chairman of the audit committee and is designated as the “audit committee financial expert” as such term is defined in Item 401(e) of Regulation S-B of the Securities Exchange Act of 1934, as amended. Messrs. Houston, Brooks and Lancaster are “independent” within the meaning of the NASD’s director independence standards. In February 2006, our board of directors and audit committee amended and restated the Audit Committee Charter, which sets for the specific functions and responsibilities of the audit committee.

Compensation Committee. The compensation committee considers executive employment agreements, adoption of employee benefit plans and other issues related to compensation and employee benefits. The compensation committee is comprised of Phillip G. Lancaster and David L. Houston, both of whom are “non-employee directors” as defined by Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, and “outside directors” as defined by Section 162(m) of the Internal Revenue Code.

Because we are considered to be controlled by Charles E. Davidson under The Nasdaq National Market rules, we are eligible for exemptions from provisions of these rules requiring that a majority of our board of directors be comprised of independent directors and a nominating and corporate governance committee composed entirely of independent directors and written charters addressing specified matters. We have elected to take advantage of certain of these exemptions. Upon consummation of this offering, however, we will cease to be a controlled company within the meaning of these rules. Accordingly, we will be required to comply with these provisions after the specified transition periods.

Members of our board of directors who are also our officers or employees do not receive compensation for their services as directors. We pay our non-employee directors a monthly retainer of $1,000 and a per meeting attendance fee of $500 and reimburse all ordinary and necessary expenses incurred by non-employee directors in the conduct of our business.

During 2005, we implemented our 2005 Stock Incentive Plan. Under the 2005 Stock Incentive Plan, each non-employee director was granted nonqualified stock options during 2005 to purchase 20,000 shares of our common stock at an exercise price of $3.36, an amount equal to the fair market value of our common stock on the date of grant. Options granted to eligible non-employee directors under the 2005 Stock Incentive Plan vest in 36 equal monthly installments beginning on the date of grant and are exercisable for a period of ten years beginning on the date of grant.

None of our executive officers serves, or has served during the past year, as a member of the board of directors or compensation committee of any other company that has one or more executive officers serving as a member of our board of directors or compensation committee.

The following table sets forth information for the fiscal years ended December 31, 2005, 2004 and 2003 with respect to compensation earned by our chief executive officer and by our three other highest paid executive officers as of the end of the last fiscal year.

The following table sets forth certain information concerning option grants made to named executive officers during 2005 pursuant to our 2005 Stock Incentive Plan.

The following table sets forth certain information concerning the exercise of options during 2005 and the number of unexercised options held by named executive officers as of December 31, 2005.

We have implemented a 2005 Stock Incentive Plan. The purpose of the plan is to enable our company, and any of its affiliates, to attract and retain the services of the types of employees, consultants and directors who will contribute to our company’s long range success and to provide incentives which are linked directly to increases in share value which will inure to the benefit of our stockholders. The plan provides a means by which eligible recipients of awards may be given an opportunity to benefit from increases in value of our common stock through the granting of incentive stock options and nonstatutory stock options.

Eligible award recipients are our employees, consultants and directors and our affiliates. Incentive stock options may be granted only to our employees. Awards other than incentive stock options may be granted to

employees, consultants and directors. The shares that may be issued pursuant to awards consist of our authorized but unissued common stock, and the maximum aggregate amount of such common stock which may be issued upon exercise of all awards under the plan, including incentive stock options, may not exceed 1,904,606 shares, subject to adjustments to reflect certain corporate transactions or changes in our capital structure.

In 2005, we granted options to employees and certain non-employee directors to purchase a total of 997,269 shares of our common stock under the plan. These options have a weighted average exercise price of $5.62 per share, have a term of ten years and vest in 36 equal monthly installments beginning on the date of grant. In addition, we have granted options to eligible non-employee directors as described in “—Director Compensation” above.

In May 1999, we entered into an employment agreement with Mike Liddell. The agreement has a five year term and automatically renews for successive one-year terms thereafter. The agreement provides for an annual base salary of $200,000, adjusted for cost of living increases. Upon termination of Mr. Liddell’s employment by us without cause, Mr. Liddell is entitled to receive twelve months of his then current base salary, and all of Mr. Liddell’s then unexercisable options will become exercisable. The agreement also restricts Mr. Liddell’s use or disclosure of any of our confidential information during the term of the agreement and for a period of five years thereafter.

We entered into an oral agreement with James D. Palm with respect to his compensation and benefits, pursuant to which Mr. Palm will be entitled to an annual salary of $200,000 and, at the discretion of our board of directors, an annual cash incentive bonus. Mr. Palm will also be eligible to participate in all insurance, retirement and benefits plans available to our other employees.

The following table sets forth certain information regarding the beneficial ownership of our common stock as of the date hereof, before and after this offering, by (1) each director, (2) each named executive officer, (3) each person known or believed by us to own beneficially five percent or more of our outstanding common stock, (4) all directors and executive officers as a group and (5) each selling stockholder. Except as otherwise indicated, the beneficial owners named in the table below have sole voting and investment power with respect to all shares of capital stock held by them.

Pursuant to an agreement dated April 14, 2004, between us and CD Holdings, L.L.C., an entity controlled by Charles E. Davidson, one of our principal stockholders, CD Holdings agreed, subject to certain conditions, to back-stop our 2004 rights offering by purchasing all of the shares of our common stock that were not otherwise subscribed for by the other holders of subscription rights under their basic subscription privileges and over-subscription privileges. In return for its agreement to back-stop the rights offering, CD Holdings received a commitment fee equal to 2% of the gross proceeds of the rights offering, or $240,000, which was applied to the subscription price payable upon exercise of the rights issued to it in the rights offering.

In connection with our 2004 rights offering, we entered into a $3,000,000 revolving credit facility dated April 30, 2004 with CD Holdings. Borrowings under the CD Holdings credit facility were due on the earlier of the closing of the rights offering or August 1, 2005, and bore interest at the rate of 10.0% per annum. The CD Holdings credit facility provided that if the rights offering was not completed, CD Holdings had the right to convert any borrowings plus any accrued but unpaid interest under the facility into shares of our common stock at a conversion price equal to $1.20 per share. Under the CD Holdings credit facility, CD Holdings had the option to apply the outstanding principal amount and any accrued but unpaid interest either (1) to the subscription price payable upon exercise of the rights issued to CD Holdings in the rights offering, or (2) to the purchase price for the common stock. Upon closing of the rights offering, $500,000 had been borrowed on the facility to fund a part of our 2004 drilling program. CD Holdings applied all amounts due it under this credit facility to the exercise price payable upon exercise of rights it received in the rights offering. See “Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Liquidity and Capital Resources—Credit Facilities” incorporated by reference in this prospectus for additional information regarding this credit facility.

Effective April 1, 2005, we entered into an administrative services agreement with Bronco Drilling Company, Inc. Under this agreement, we agreed to provide certain services to Bronco Drilling Company including accounting, human resources, legal and technical support services. In return for these services, Bronco Drilling Company agreed to pay us an annual fee of approximately $414,000 payable in equal monthly installments during the term of this agreement. In addition, Bronco Drilling Company leased approximately 1,200 square feet of office space from us for its headquarters located in Oklahoma City, Oklahoma for which it agreed to pay us annual rent of $20,880 in equal monthly installments. The services we provide under the administrative services agreement and the fees for such services can be amended by mutual agreement of the parties. In January 2006, Bronco Drilling Company reduced the level of administrative services being provided by us and increased the office space it leases to approximately 2,500 square feet. As a result, our annual fee for administrative services was reduced to approximately $150,000 and our annual rental was increased to approximately $44,000. The administrative services agreement has a three-year term, and upon expiration of that term the agreement will continue on a month-to-month basis until cancelled by either party with at least 30 days prior written notice. The administrative services agreement is terminable (1) by Bronco Drilling Company at any time with at least 30 days prior written notice to us and (2) by either party if the other party is in material breach and such breach has not been cured within 30 days of receipt of written notice of such breach. Prior to entry into this administrative services agreement, Bronco Drilling Company reimbursed us for our dedicated employee time, office space and general and administrative costs based upon the pro rata share of time its employees spent performing services for Bronco Drilling Company. In 2005, 2004 and 2003, we received payments from Bronco Drilling Company for such services and overhead totaling approximately $353,000, $115,000 and $33,000, respectively. Three of our directors, Mike Liddell, David L. Houston and Phillip G. Lancaster, are also directors of Bronco Drilling Company and Mr. Liddell serves as chairman of Bronco Drilling Company. Wexford Capital

LLC is the sole manager of Bronco Drilling Holdings, L.L.C., which beneficially owned 47.3% of the common stock of Bronco Drilling Company as of March 17, 2006. Charles E. Davidson is the Chairman of Wexford Capital.

In addition, our personnel help manage the oil and natural gas production and oil and natural gas related assets owned by certain of our affiliates. In return for these services, we are reimbursed for our dedicated employee time, office space and general and administrative costs based upon the pro rata share of time our employees spend performing these services. In 2005, 2004 and 2003, we received payments from these affiliates, excluding Bronco Drilling Company, for such services and overhead totaling approximately $5,876,000, $2,030,000 and $732,000, respectively.

The following summary description of our capital stock is qualified in its entirety by reference to our certificate of incorporation and bylaws, each of which is incorporated by reference in this prospectus.

We are currently authorized to issue up to 55,000,000 shares of common stock, par value $0.01 per share, of which there were 32,180,326 shares outstanding as of the date hereof. Holders of our common stock are entitled to cast one vote for each share held of record on each matter submitted to a vote of stockholders. There is no cumulative voting for election of directors. Subject to the prior rights of any series of preferred stock which may from time to time be outstanding, if any, holders of our common stock are entitled to receive ratably dividends when, as, and if declared by the board of directors out of funds legally available therefor and, upon the liquidation, dissolution or winding up of the company, are entitled to share ratably in all assets remaining after payment of liabilities and payment of accrued dividends and liquidation preferences on the preferred stock, if any. There are no redemption or sinking fund provisions that are applicable to our common stock. Subject only to the requirements of the DGCL, the board of directors may issue shares of our common stock without stockholder approval, at any time and from time to time, to such persons and for such consideration as the board of directors deems appropriate. Holders of our common stock have no preemptive rights and have no rights to convert their common stock into any other securities. The outstanding common stock is validly authorized and issued, fully paid, and nonassessable.

We are authorized to issue up to 5,000,000 shares of preferred stock, par value $.01 per share. Shares of preferred stock may be issued from time to time in one or more series as the board of directors, by resolution or resolutions, may from time to time determine, each of said series to be distinctively designated. The voting powers, preferences and relative, participating, optional and other special rights, and the qualifications, limitations or restrictions thereof, if any, of each such series of preferred stock may differ from those of any and all other series of preferred stock at any time outstanding, and, subject to certain limitations of our certificate of incorporation and the DGCL, the board of directors may fix or alter, by resolution or resolutions, the designation, number, voting powers, preferences and relative, participating, optional and other special rights, and qualifications, limitations and restrictions thereof, of each such series of preferred stock.

The issuance of any such preferred stock could adversely affect the rights of the holders of our common stock and therefore, reduce the value of the common stock. The ability of the board of directors to issue preferred stock could discourage, delay, or prevent a takeover of us. See “Risk Factors.”

Anti-takeover Effects of Provisions of Our Certificate of Incorporation and Our Bylaws

Some provisions of our certificate of incorporation and our bylaws contain provisions that could make it more difficult to acquire us by means of a merger, tender offer, proxy contest or otherwise, or to remove our incumbent officers and directors. These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging such proposals because negotiation of such proposals could result in an improvement of their terms.

Preferred stock. Our certificate of incorporation permits our board of directors to authorize and issue one or more series of preferred stock, which may render more difficult or discourage an attempt to change control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary

obligations, the board of directors were to determine that a takeover proposal is not in our best interest, the board of directors could cause shares of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group.

Stockholder meetings. Our bylaws provide that a special meeting of stockholders may be called only by the Chairman of the Board, the President, or upon the request of a majority of our board of directors or the holders of not less than sixty-six percent of our outstanding shares entitled to vote at such a special meeting.

Requirements for advance notification of stockholder nominations and proposals. Our bylaws and certificate of incorporation establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors.

Amendment of the bylaws. Under Delaware law, the power to adopt, amend or repeal bylaws is conferred upon the stockholders. A corporation may, however, in its certificate of incorporation also confer upon the board of directors the power to adopt, amend or repeal its bylaws. Both our certificate of incorporation and bylaws grant our board of directors and stockholders the power to adopt, amend and repeal our bylaws.

Removal of Directors. Our bylaws provide that members of our board of directors may only be removed for cause and only by the affirmative vote of holders of at least 66% of the voting power of all then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class.

The provisions of our certificate of incorporation and bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

We and the selling stockholders have entered into an underwriting agreement with the underwriters named below with respect to the shares being offered. Subject to the terms and conditions of the underwriting agreement, the underwriters named below have severally agreed to purchase from the selling stockholders the number of shares of our common stock set forth opposite their names on the table below at the public offering price, less the underwriting discounts and commissions shown on the cover page of this prospectus as follows:

The underwriting agreement provides that the underwriters’ obligation to purchase shares of our common stock depend on the satisfaction of the conditions contained in the underwriting agreement. The conditions contained in the underwriting agreement include the condition that the representations and warranties made by us and the selling stockholders to the underwriters are true, that there has been no material adverse change to our condition or in the financial markets and that we and the selling stockholders deliver to the underwriters customary closing documents. The underwriters are obligated to purchase all of the shares of common stock (other than those covered by the over-allotment option described below) if they purchase any of the shares.

The underwriters propose to offer the shares of common stock to the public at the public offering price set forth on the cover of this prospectus. The underwriters may offer the common stock to securities dealers at the price to the public less a concession not in excess of $ per share. Security dealers may reallow a concession not in excess of $ per share to other dealers. After the shares of common stock are released for sale to the public, the underwriters may vary the offering price and other selling terms from time to time.

We have granted to the underwriters an option, exercisable for 30 days from the date of the underwriting agreement, to purchase up to 907,500 additional shares at the public offering price per share less the underwriting discounts and commissions shown on the cover page of this prospectus. The underwriters may exercise this option solely to cover over-allotments, if any, made in connection with this offering.

The following table summarizes the compensation to be paid to the underwriters by us and the selling stockholders in connection with this offering.

We estimate our expenses associated with the offering, excluding underwriting discounts and commissions, will be approximately $500,000.

We and the selling stockholders have agreed to indemnify the underwriters against certain liabilities, including liabilities under the federal securities laws, or to contribute to payments that may be required to be made in respect of these liabilities.

We, our officers and directors, and the selling stockholders and certain of their affiliates have agreed that, for a period of 90 days from the date of this prospectus, we and they will not, without the prior written consent of Johnson Rice & Company L.L.C., directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of any share of common stock or any securities convertible into or exercisable or exchangeable for common stock, or file any registration statement under the Securities Act of 1933 with respect to any of the foregoing or enter into any swap or any other agreement or transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the common stock, except for the sale to the underwriters in this offering, the issuance by us of any securities or options to purchase common stock under existing, amended or new employee benefit plans maintained by us and the filing of or amendment to any registration statement related to the foregoing, the issuance by us of securities in exchange for or upon conversion of our outstanding securities described herein, the filing of or an amendment to any registration statement pursuant to registration rights held by third parties not subject to a lock-up agreement or certain transfers in the case of officers, directors or other stockholders in the form of bona fide gifts, intra family transfers and transfers related to estate planning matters. Notwithstanding the foregoing, if (1) during the last 17 days of such 90-day restricted period we issue an earnings release or (2) prior to the expiration of such 90-day restricted period we announce that we will release earnings results during the 16-day period beginning on the last day of the 90-day restricted period, the foregoing restrictions shall continue to apply until the expiration of the 90-day period beginning on the issuance of the earnings release; provided, however, that this sentence will not apply if, as of the expiration of the restricted period, shares of our common stock are “actively-traded securities” as defined in Regulation M. The underwriters have advised us that they do not have any present intent to release the lock-up agreements prior to the expiration of the applicable restricted period.

The underwriters may engage in over-allotment, stabilizing transactions, syndicate covering transactions, penalty bids and passive market making in accordance with Regulation M under the Securities Exchange Act of 1934, as amended. Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position. Covered short sales are sales made in an amount not greater than the number of shares available for purchase by the underwriters under their over-allotment option. The underwriters may close out a covered short sale by exercising their over-allotment option or purchasing shares in the open market. Naked short sales are sales made in an amount in excess of the number of shares available under the over-allotment option. The underwriters must close out any naked short sale by purchasing shares in the open market. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Syndicate covering transactions involve purchases of the shares of common stock in the open market after the distribution has been completed in order to cover syndicate short positions. Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the shares of common stock originally sold by such syndicate member is purchased in a syndicate covering transaction to cover syndicate short positions. Penalty bids may have the effect of deterring syndicate members from selling to people who have a history of quickly selling their shares. In passive market making, market makers in the shares of common stock who are underwriters or prospective underwriters may, subject to certain limitations, make bids for or purchases of the shares of common stock until the time, if any, at which a stabilizing bid is made. These stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the shares of common stock to be higher than it would otherwise be in the absence of these transactions. The underwriters are not required to engage in these activities, and may end any of these activities at any time.

The validity of the shares of common stock to be offered hereby will be passed upon by Akin Gump Strauss Hauer & Feld LLP. Certain legal matters will be passed upon for the underwriters by Porter & Hedges, L.L.P.

The following is a description of the meanings of some of the oil and natural gas industry terms used in this prospectus.

3-D seismic. Geophysical data that depict the subsurface strata in three dimensions. 3-D seismic typically provides a more detailed and accurate interpretation of the subsurface strata than 2-D, or two-dimensional, seismic.

Bbl. Stock tank barrel, or 42 U.S. gallons liquid volume, used in this prospectus in reference to crude oil or other liquid hydrocarbons.

Boe. Barrels of oil equivalent, with six thousand cubic feet of natural gas being equivalent to one barrel of oil.

Btu or British thermal unit. The quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

Coalbed methane (CBM). Natural gas formed as a byproduct of the coal formation process, which is trapped in coal seams and produced by non-traditional means.

Completion. The process of treating a drilled well followed by the installation of permanent equipment for the production of natural gas or oil, or in the case of a dry hole, the reporting of abandonment to the appropriate agency.

Condensate. Liquid hydrocarbons associated with the production of a primarily natural gas reserve.

Developed acreage. The number of acres that are allocated or assignable to productive wells or wells capable of production.

Dry hole. A well found to be incapable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production exceed production expenses and taxes.

Exploratory well. A well drilled to find and produce natural gas or oil reserves not classified as proved, to find a new reservoir in a field previously found to be productive of natural gas or oil in another reservoir or to extend a known reservoir.

Field. An area consisting of either a single reservoir or multiple reservoirs, all grouped on or related to the same individual geological structural feature and/or stratigraphic condition.

Finding and development costs. Capital costs incurred in the acquisition, exploitation and exploration of proved oil and natural gas reserves divided by proved reserve additions and revisions to proved reserves.

Identified drilling locations. Total gross locations specifically identified by management to be included in the Company’s multi-year drilling activities on existing acreage. The Company’s actual drilling activities may change depending on the availability of capital, regulatory approvals, seasonal restrictions, oil and natural gas prices, costs, drilling results and other factors.

Net acres or net wells. The sum of the fractional working interest owned in gross acres or gross wells, as the case may be.

Net revenue interest (NRI). An owner’s interest in the revenues of a well after deducting proceeds allocated to royalty and overriding interests.

Play. A set of discovered or prospective oil and/or natural gas accumulations sharing similar geologic, geographic and temporal properties, such as source rock, reservoir structure, timing, trapping mechanism and hydrocarbon type.

Plugging and abandonment. Refers to the sealing off of fluids in the strata penetrated by a well so that the fluids from one stratum will not escape into another or to the surface. Regulations of all states require plugging of abandoned wells.

Present value of future net revenues (PV-10). The present value of estimated future revenues to be generated from the production of proved reserves, before income taxes, of proved reserves calculated in accordance with Financial Accounting Standards Board guidelines, net of estimated production and future development costs, using prices and costs as of the date of estimation without future escalation, without giving effect to hedging activities, non-property related expenses such as general and administrative expenses, debt service and depreciation, depletion and amortization, and discounted using an annual discount rate of 10%.

Productive well. A well that is found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of the production exceed production expenses and taxes.

Proved developed reserves (PDP). Reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

Proved reserves. The estimated quantities of oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be commercially recoverable in future years from known reservoirs under existing economic and operating conditions.

Proved undeveloped reserves (PUD). Proved reserves that are expected to be recovered from new wells drilled to known reservoirs on undrilled acreage for which the existence and recoverability of such reserves can be estimated with reasonable certainty, or from existing wells on which a relatively major expenditure is required to establish production.

Recompletion. The process of re-entering an existing wellbore that is either producing or not producing and completing new reservoirs in an attempt to establish or increase existing production.

Reservoir. A porous and permeable underground formation containing a natural accumulation of producible natural gas and/or oil that is confined by impermeable rock or water barriers and is separate from other reservoirs.

Standardized Measure. The present value of estimated future cash inflows from proved oil and natural gas reserves, less future development, abandonment, production and future income tax expenses, discounted at 10% per annum to reflect timing of future cash flows and using the same pricing assumptions as were used to calculate PV-10. Standardized Measure differs from PV-10 because Standardized Measure includes the effect of future income taxes.

Undeveloped acreage. Lease acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves.

Working interest (WI). The operating interest that gives the owner the right to drill, produce and conduct operating activities on the property and receive a share of production and requires the owner to pay a share of the costs of drilling and production operations.

The following table sets forth all expenses payable by the Registrant in connection with the registration of the common stock. The selling stockholders will not pay any of the Registration expenses.

The Company is empowered by Section 145 of the DGCL, subject to the procedures and limitations stated therein, to indemnify certain parties. Section 145 of the DGCL provides in part that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Similar indemnity is authorized for such persons against expenses (including attorneys’ fees) actually and reasonably incurred in the defense or settlement of any threatened, pending or completed action or suit by or in the right of the corporation, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and provided further that (unless a court of competent jurisdiction otherwise provides) such person shall not have been adjudged liable to the corporation. Any such indemnification may be made only as authorized in each specific case upon a determination by the stockholders or disinterested directors that indemnification is proper because the indemnitee has met the applicable standard of conduct. Where an officer or a director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director actually or reasonably incurred. Section 145 provides further that indemnification pursuant to its provisions is not exclusive of other rights of indemnification to which a person may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

The Company’s Bylaws provide that the Company shall indemnify and advance expenses to each person who is a director or officer of the Company to the fullest extent permitted under Section 145 of the DGCL, and such indemnity and advancement of expenses shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

Article VI of the Company’s Certificate of Incorporation eliminates the personal liability of the Company’s directors to the fullest extent permitted under Section 102(b)(7) of the DGCL, as amended. Such section permits a company’s certificate of incorporation to eliminate or limit the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director: (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional

misconduct or a knowing violation of law; (iii) under Section 174 of the DGCL (which addresses director liability for unlawful payment of a dividend or unlawful stock purchase or redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

Article VI of the Bylaws of the Company provides that the Company shall, to the fullest extent permitted by Delaware law, indemnify any and all persons whom it shall have power to indemnify against any and all of the costs, expenses, liabilities or other matters incurred by them by reason of having been officers or directors of the Company, any such subsidiary of the Company or of any other corporation for which he acted as officer or director at the request of the Company.

The Company maintains director and officer liability insurance providing insurance protection for specified liabilities under specified terms.

The Company has adopted provisions in its Bylaws and in its Certificate which provide for indemnification of its officers and directors to the maximum extent permitted under the DGCL.

The following is a list of exhibits filed as a part of this registration statement.

(a) Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”) may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the

securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(b) (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof.

Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Oklahoma City, Oklahoma on the 21st day of April, 2006.
