RISK FACTORS

      In deciding whether to participate in the exchange offer, you should consider the following risks. You should consider carefully these risks along with the other information in this document and the documents to which we have referred you before tendering your existing notes.

Risk Factors Relating to Our Business

	A decrease in oil and gas prices may adversely affect our results of operations and financial condition.

      Our success is highly dependent on prices for oil and gas, which are extremely volatile. Any substantial or extended decline in the price of oil or gas would have a material adverse effect on us. Oil and gas markets are both seasonal and cyclical. The prices of oil and gas depend on factors we cannot control such as weather, economic conditions, levels of production, actions by OPEC and other countries and government actions. Prices of oil and gas will affect the following aspects of our business:

	•	our revenues, cash flows and earnings;
	•	the amount of oil and gas that we are economically able to produce;
	•	our ability to attract capital to finance our operations and the cost of the capital;
	•	the amount we are allowed to borrow under our senior bank credit facility;
	•	the value of our oil and gas properties; and
	•	the profit or loss we incur in exploring for and developing our reserves.

	We may be required to retroactively pay royalties to the Minerals Management Service on one of our properties which could reduce revenues and reserves.

      Our Medusa deepwater property is eligible for royalty suspensions pursuant to the Deep Water Royalty Relief Act. However, the federal offshore leases covering this property contain “price threshold” provisions for oil and gas prices. Under these “price threshold” provisions, if the average monthly New York Mercantile Exchange (NYMEX) sales price for oil or gas during a fiscal year exceeds the price threshold for oil or gas, respectively, then royalties on the associated production must be paid to the Minerals Management Service (MMS) at the rate stipulated in the lease. The price thresholds are adjusted annually by the implicit price deflator for the GDP. The determination of whether or not royalties are due as a result of the average NYMEX price exceeding the price threshold is made during the first quarter of the succeeding year. Any royalty payments due must be made shortly after this determination is made. If a royalty payment is due for all production during a year as a result of exceeding the price threshold, the lessee is required to make monthly royalty payments during the succeeding fiscal year for the succeeding year’s production. If at the end of any year the average NYMEX price is below the price threshold, the lessee can apply for a refund for any associated royalties paid during the year and the lessee will not be required to pay royalties monthly during the succeeding year for the succeeding year’s production.

      The thresholds and the average NYMEX prices are calculated by the MMS. The average NYMEX price for 2003 was $31.08 per barrel of oil and $5.49 per MMBtu of natural gas. For the year ended December 31, 2003, the thresholds were $32.81 per barrel of oil and $4.10 per MMBtu of natural gas. As a result, we will pay royalties related to 2003 gas production for Medusa, which commenced production in late November 2003, and will make monthly royalty payments for 2004 gas production during 2004. Our actual liability for 2004 oil royalties, if any, cannot be determined until after the end of 2004.

      In the year succeeding the year in which any of our properties became subject to royalties as result of the average NYMEX price exceeding the price threshold, the portion of reserves attributable to potential future royalties would not be included in a year-end reserve report. However, if the average NYMEX prices were below the price thresholds in subsequent years, our reserves would be increased to reflect reserves previously attributed to future royalties. As a result, reported oil and gas reserves could materially

	Our reserve information represents estimates that may turn out to be incorrect if the assumptions upon which these estimates are based are inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present values of our reserves.

      The process of estimating oil and gas reserves is complex. It requires interpretations of available technical data and various assumptions, including assumptions relating to economic factors. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves shown in this prospectus.

      In order to prepare these estimates, we must project production rates and the timing of development expenditures. The assumptions regarding the timing and costs to commence production from our deepwater wells used in preparing our reserves are often subject to revisions over time as described under “— Our deepwater operations have special operational risks that may negatively affect the value of those assets.” We must also analyze available geological, geophysical, production and engineering data, the extent, quality and reliability of which can vary. In addition, the process requires us to make economic assumptions, such as future oil and gas prices, drilling and operating expenses, capital expenditures, taxes and the availability of funds. Therefore, estimates of oil and gas reserves are inherently imprecise.

      Actual future production, oil and gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and gas reserves most likely will vary from our estimates. Any significant variance could materially affect the estimated quantities and present value of reserves shown in this prospectus. In addition, we may adjust estimates of proved reserves to reflect production history, results of exploration and development, prevailing oil and gas prices and other factors, many of which are beyond our control.

      You should not assume that the present value of future net cash flows from our proved reserves referred to in this prospectus is the current market value of our estimated oil and gas reserves. In accordance with SEC requirements, we generally base the estimated discounted future net cash flows from our proved reserves on prices and costs on the date of the estimate. Actual future prices and costs may differ materially from those used in the present value estimate.

      Information about reserves constitutes forward-looking information. See “Forward-Looking Statements” for information regarding forward-looking information. The discounted present value of our oil and gas reserves is prepared in accordance with guidelines established by the SEC. A purchaser of reserves would use numerous other factors to value our reserves. The discounted present value of reserves, therefore, does not represent the fair market value of those reserves.

      On December 31, 2003, approximately 53% of the discounted present value of our estimated net proved reserves were proved undeveloped. Proved undeveloped oil reserves represented 58% of total proved oil reserves. Substantially all of these proved undeveloped reserves were attributable to our deepwater properties. Development of these properties is subject to additional risks as described above.

	Unless we are able to replace reserves which we have produced, our cash flows and production will decrease over time.

      Our future success depends upon our ability to find, develop and acquire oil and gas reserves that are economically recoverable. As is generally the case for Gulf properties, our producing properties usually have high initial production rates, followed by a steep decline in production. As a result, we must

11

      Also, because of the short life of our reserves, our return on the investment we make in our oil and gas wells and the value of our oil and gas wells will depend significantly on prices prevailing during relatively short production periods.

	A significant part of the value of our production and reserves is concentrated in a small number of offshore properties, and any production problems or inaccuracies in reserve estimates related to those properties would adversely impact our business.

      During 2003, 64% of our daily production came from two of our properties in the Gulf of Mexico. Moreover, one property accounted for 51% of our production during this period. In addition, at December 31, 2003 most of our proved reserves were located in four fields in the Gulf of Mexico, with approximately 94% of our total net proved reserves attributable to these properties. If mechanical problems, storms or other events curtailed a substantial portion of this production, or if the actual reserves associated with any one of these producing properties are less than our estimated reserves, our results of operations and financial condition could be adversely affected.

	Our focus on exploration projects increases the risks inherent in our oil and gas activities.

      Our business strategy focuses on replacing reserves through exploration, where the risks are greater than in acquisitions and development drilling. Although we have been successful in exploration in the past, we cannot assure you that we will continue to increase reserves through exploration or at an acceptable cost. Additionally, we are often uncertain as to the future costs and timing of drilling, completing and producing wells. Our drilling operations may be curtailed, delayed or canceled as a result of a variety of factors, including:

	•	unexpected drilling conditions;
	•	pressure or inequalities in formations;
	•	equipment failures or accidents;
	•	adverse weather conditions;
	•	compliance with governmental requirements; and
	•	shortages or delays in the availability of drilling rigs and the delivery of equipment.

	Because we do not control and do not operate all of our properties, especially our deepwater properties, we have limited influence over their development.

      We do not operate all of our properties and have limited influence over the operations of some of these properties, particularly our deepwater properties. Our lack of control could result in the following:

	•	the operator may initiate exploration or development on a faster or slower pace than we prefer;
	•	the operator may propose to drill more wells or build more facilities on a project than we have funds for or that we deem appropriate, which may mean that we are unable to participate in the project or share in the revenues generated by the project even though we paid our share of exploration costs; and

12

---

Table of Contents

	•	if an operator refuses to initiate a project, we may be unable to pursue the project.

Any of these events could materially reduce the value of our properties.

	Our deepwater operations have special operational risks that may negatively affect the value of those assets.

      Drilling operations in the deepwater area are by their nature more difficult and costly than drilling operations in shallow water. Deepwater drilling operations require the application of more advanced drilling technologies, involving a higher risk of technological failure and usually resulting in significantly higher drilling costs than shallow water drilling operations. Deepwater wells are completed using sub-sea completion techniques that require substantial time and the use of advanced remote installation equipment. These operations involve a high risk of mechanical difficulties and equipment failures that could result in significant cost overruns.

      In deepwater, the time required to commence production following a discovery is much longer than in shallow water and on-shore. Our deepwater discoveries and prospects will require the construction of expensive production facilities and pipelines prior to the beginning of production. We cannot estimate the costs and timing of the construction of these facilities with certainty, and the accuracy of our cost estimates will be affected by a number of factors beyond our control, including the following:

	•	decisions made by the operators of our deepwater wells;
	•	the availability of materials necessary to construct the facilities;
	•	the proximity of our discoveries to pipelines; and
	•	the price of oil and natural gas.

      Delays and cost overruns in the commencement of production will affect the value of our deepwater prospects and the discounted present value of reserves attributable to those prospects.

	Competitive industry conditions may negatively affect our ability to conduct operations.

      We operate in the highly competitive areas of oil and gas exploration, development and production. We compete for the purchase of leases in the Gulf of Mexico from the U.S. government and from other oil and gas companies. These leases include exploration prospects as well as properties with proved reserves. Factors that affect our ability to compete in the marketplace include:

	•	our access to the capital necessary to drill wells and acquire properties;
	•	our ability to acquire and analyze seismic, geological and other information relating to a property;
	•	our ability to retain the personnel necessary to properly evaluate seismic and other information relating to a property;
	•	the location of, and our ability to access, platforms, pipelines and other facilities used to produce and transport oil and gas production;
	•	the standards we establish for the minimum projected return on an investment of our capital; and
	•	the availability of alternate fuel sources.

      Our competitors include major integrated oil companies, substantial independent energy companies, affiliates of major interstate and intrastate pipelines, and national and local gas gatherers, many of which possess greater financial, technological and other resources than we do.

13

Table of Contents

	Our competitors may use superior technology which we may be unable to afford or which would require costly investment by us in order to compete.

      Our industry is subject to rapid and significant advancements in technology, including the introduction of new products and services using new technologies. As our competitors use or develop new technologies, we may be placed at a competitive disadvantage, and competitive pressures may force us to implement new technologies at a substantial cost. In addition, our competitors may have greater financial, technical and personnel resources that allow them to enjoy technological advantages and may in the future allow them to implement new technologies before we can. We cannot be certain that we will be able to implement technologies on a timely basis or at a cost that is acceptable to us. One or more of the technologies that we currently use or that we may implement in the future may become obsolete, and we may be adversely affected. For example, marine seismic acquisition technology has been characterized by rapid technological advancements in recent years, and further significant technological developments could substantially impair our 3-D seismic data’s value.

	We may not be able to replace our reserves or generate cash flows if we are unable to raise capital.

      We will be required to make substantial capital expenditures to develop our existing reserves, and to discover new oil and gas reserves. Historically, we have financed these expenditures primarily with cash from operations, proceeds from bank borrowings and proceeds from the sale of debt and equity securities. We cannot assure you that we will be able to raise capital in the future. We also make offers to acquire oil and gas properties in the ordinary course of our business. If these offers are accepted, our capital needs may increase substantially.

      We expect to continue using our senior bank credit facility to borrow funds to supplement our available cash. The amount we may borrow under our senior bank credit facility may not exceed a borrowing base determined by the lenders under such facility based on their projections of our future production, future production costs, taxes, commodity prices and other factors deemed relevant by our lenders. We cannot control the assumptions the lenders use to calculate our borrowing base. The lenders may, without our consent, adjust the borrowing base semiannually or in situations where we purchase or sell assets or issue debt securities. If our borrowings under the senior bank credit facility exceed the borrowing base, the lenders may require that we repay the excess. If this were to occur, we might have to sell assets or seek financing from other sources. Sales of assets could further reduce the amount of our borrowing base. We cannot assure you that we would be successful in selling assets or arranging substitute financing. If we were not able to repay borrowings under our senior bank credit facility to reduce the outstanding amount to less than the borrowing base, we would be in default under our senior bank credit facility.

	Our decision to drill a prospect is subject to a number of factors and we may decide to alter our drilling schedule or not drill at all.

      We describe our current prospects and our plans to explore these prospects in this prospectus, including the materials incorporated by reference. A prospect is a property on which we have identified what our geoscientists believe, based on available seismic and geological information, to be indications of hydrocarbons. Our prospects are in various stages of evaluation, ranging from a prospect which is ready to drill to a prospect which will require substantial additional seismic data processing and interpretation. Whether we ultimately drill a prospect may depend on the following factors:

	•	receipt of additional seismic data or the reprocessing of existing data;
	•	material changes in oil or gas prices;
	•	the costs and availability of drilling rigs;
	•	the success or failure of wells drilled in similar formations or which would use the same production facilities;

14

---

Table of Contents

	•	availability and cost of capital;
	•	changes in the estimates of the costs to drill or complete wells;
	•	our ability to attract other industry partners to acquire a portion of the working interest to reduce exposure to costs and drilling risks; and
	•	decisions of our joint working interest owners.

      We will continue to gather data about our prospects, and it is possible that additional information may cause us to alter our drilling schedule or determine that a prospect should not be pursued at all. You should understand that our plans regarding our prospects are subject to change.

	Weather, unexpected subsurface conditions, and other unforeseen operating hazards may adversely impact our ability to conduct business.

      There are many operating hazards in exploring for and producing oil and gas, including:

	•	our drilling operations may encounter unexpected formations or pressures which could cause damage to equipment or personal injury;
	•	we may experience equipment failures which curtail or stop production; and
	•	we could experience blowouts or other damages to the productive formations that may require a well to be re-drilled or other corrective action to be taken.

      In addition, any of the foregoing may result in environmental damages for which we will be liable. Moreover, a substantial portion of our operations are offshore and are subject to a variety of risks peculiar to the marine environment such as capsizing, collisions, hurricanes and other adverse weather conditions. These conditions can cause substantial damage to facilities and interrupt production. Offshore operations are also subject to more extensive governmental regulation.

      We cannot assure you that we will be able to maintain adequate insurance at rates we consider reasonable to cover our possible losses from operating hazards. The occurrence of a significant event not fully insured or indemnified against could materially and adversely affect our financial condition and results of operations.

	We may not have production to offset hedges; by hedging, we may not benefit from price increases.

      Part of our business strategy is to reduce our exposure to the volatility of oil and gas prices by hedging a portion of our production. In a typical hedge transaction, we will have the right to receive from the other parties to the hedge the excess of the fixed price specified in the hedge over a floating price based on a market index, multiplied by the quantity hedged. If the floating price exceeds the fixed price, we are required to pay the other parties this difference multiplied by the quantity hedged. We are required to pay the difference between the floating price and the fixed price when the floating price exceeds the fixed price regardless of whether we have sufficient production to cover the quantities specified in the hedge. Significant reductions in production at times when the floating price exceeds the fixed price could require us to make payments under the hedge agreements even though such payments are not offset by sales of production. Hedging will also prevent us from receiving the full advantage of increases in oil or gas prices above the fixed amount specified in the hedge. We also enter into price “collars” to reduce the risk of changes in oil and gas prices. Under a collar, no payments are due by either party so long as the market price is above a floor set in the collar and below a ceiling. If the price falls below the floor, the counter-party to the collar pays the difference to us and if the price is above the ceiling, we pay the counter-party the difference.

Table of Contents

	Compliance with environmental and other government regulations could be costly and could negatively impact production.

      Our operations are subject to numerous laws and regulations governing the operation and maintenance of our facilities and the discharge of materials into the environment or otherwise relating to environmental protection. These laws and regulations may:

	•	require that we acquire permits before commencing drilling;
	•	restrict the substances that can be released into the environment in connection with drilling and production activities;
	•	limit or prohibit drilling activities on protected areas such as wetlands or wilderness areas; and
	•	require remedial measures to mitigate pollution from former operations, such as dismantling abandoned production facilities.

      Under these laws and regulations, we could be liable for personal injury and clean-up costs and other environmental and property damages, as well as administrative, civil and criminal penalties. We maintain limited insurance coverage for sudden and accidental environmental damages. We do not believe that insurance coverage for environmental damages that occur over time is available at a reasonable cost. Also, we do not believe that insurance coverage for the full potential liability that could be caused by sudden and accidental environmental damages is available at a reasonable cost. Accordingly, we may be subject to liability or we may be required to cease production from properties in the event of environmental damages.

	Factors beyond our control affect our ability to market production and our financial results.

      The ability to market oil and gas from our wells depends upon numerous factors beyond our control. These factors include:

	•	the extent of domestic production and imports of oil and gas;
	•	the proximity of the gas production to gas pipelines;
	•	the availability of pipeline capacity;
	•	the demand for oil and gas by utilities and other end users;
	•	the availability of alternative fuel sources;
	•	the effects of inclement weather;
	•	state and federal regulation of oil and gas marketing; and
	•	federal regulation of gas sold or transported in interstate commerce.

      Because of these factors, we may be unable to market all of the oil or gas we produce. In addition, we may be unable to obtain favorable prices for the oil and gas we produce.

	If oil and gas prices decrease, we may be required to take write downs of the carrying value of our oil and gas properties.

      We may be required to write down the carrying value of our oil and gas properties when oil and gas prices are low or if we have substantial downward adjustments to our estimated net proved reserves, increases in our estimates of development costs or deterioration in our exploration results. Under the full cost method we use to account for our oil and gas properties, the net capitalized costs of our oil and gas properties may not exceed the present value, discounted at 10%, of future net cash flows from estimated net proved reserves, using period end oil and gas prices or prices as of the date of our auditor’s report, plus the lower of cost or fair market value of our unproved properties. If net capitalized costs of our oil and gas properties exceed this limit, we must charge the amount of the excess to earnings. This type of charge will not affect our cash flows, but will reduce the book value of our stockholders’ equity. We review the

Risk Factors Related to the Exchange Notes

	Our significant debt levels and our debt covenants may limit our future flexibility in obtaining additional financing and in pursuing business opportunities.

      As of March 31, 2004, we had approximately $238 million in long-term debt. The level of our indebtedness will have important effects on our future operations, including:

	•	a portion of our cash flow will be used to pay interest and principal on our debt and will not be available for other purposes;
	•	our senior bank credit facility contains financial tests which we must satisfy in order to continue to borrow funds under the facility, and a failure to meet these tests also may be a default under our senior bank credit facility;
	•	covenants in the exchange notes and in our existing senior subordinated notes require us to meet financial tests in order to borrow additional money, which may have the effect of limiting our flexibility in reacting to changes in our business and our ability to fund future operations and acquisitions;
	•	our ability to refinance existing debt or to obtain additional financing for capital expenditures and other purposes may be limited;
	•	we may be more leveraged than our competitors, which may place us at a competitive disadvantage; and
	•	we may be unable to adjust rapidly to changing market conditions.

      These consequences could make us more vulnerable than a less leveraged competitor in the event of a downturn in our business or general economic conditions.

	We may not be able to generate sufficient cash flow to service our existing indebtedness.

      At March 31, 2004, we had long-term indebtedness of approximately $238 million and cash and cash equivalents of $3 million. We may incur additional indebtedness after the exchange offer as we execute our business strategy.

      Our ability to make scheduled payments or to refinance our indebtedness, including $33 million of our 11% senior subordinated notes due 2005 and our senior bank credit facility, depends on our future performance and successful implementation of our strategy, both of which are subject not only to our actions but also to general economic, financial, competitive, legislative and regulatory conditions, the prevailing market prices for oil and gas and other factors beyond our control.

	The exchange notes will be effectively subordinated to our secured debt.

      The exchange notes will not be secured by any of our or the guarantors’ assets, and as such will be effectively subordinated to any secured debt that we or the guarantors may have now or may incur in the future to the extent of the value of the assets securing that debt.

	The guarantees may not be enforceable because of fraudulent conveyance laws.

      The incurrence of the guarantees by the guarantors may be subject to review under U.S. federal bankruptcy law or relevant state fraudulent conveyance laws if a bankruptcy case or lawsuit is commenced by or on behalf of the guarantors’ unpaid creditors. Under these laws, if a court were to find that, at the time such guarantor incurred a guarantee of the exchange notes, such guarantor incurred the guarantee of

17

---

Table of Contents

	•	was insolvent or was rendered insolvent;
	•	was engaged, or about to engage, in a business or transaction for which its remaining assets constituted unreasonably small capital to carry on its business; or
	•	intended to incur, or believed that it would incur, debts beyond its ability to pay as such debts matured,

then such court could void the guarantee of such guarantor or subordinate the amounts owing under such guarantee to such guarantor’s presently existing or future debt or take other actions detrimental to you. It may be asserted that the guarantors incurred their guarantees for our benefit and they incurred the obligations under the guarantees for less than reasonably equivalent value or fair consideration.

      The measure of insolvency for purposes of the foregoing considerations will vary depending upon the law of the jurisdiction that is being applied in any such proceeding. Generally, a company would be considered insolvent if, at the time it incurred the debt or issued the guarantee, either:

	•	the sum of its debts, including contingent liabilities, is greater that its assets, at fair valuation; or
	•	the present fair saleable value of its assets is less than the amount required to pay the probable liability on its total existing debts and liabilities, including contingent liabilities, as they become absolute and mature.

      If a guarantee is voided as a fraudulent conveyance or found to be unenforceable for any other reason, you will not have a claim against that obligor and will only be a creditor of us or any guarantor whose obligation was not set aside or found to be unenforceable.

	We may not be able to repurchase exchange notes upon a change in control.

      If a change in control occurs, you will have the right to require us to repurchase all or any part of your exchange notes as described under “Description of the Exchange Notes — Change in Control.” Our senior bank credit facility prohibits the repurchase of the exchange notes. In order to repurchase the exchange notes, we would be required to repay our debt under our senior bank credit facility or obtain consents from our bank lenders. If we cannot repay the senior bank credit facility or obtain the consents, we would not be able to repurchase the exchange notes. Also, we may not have sufficient funds available or be able to obtain the financing necessary to repurchase the exchange notes.

      If a change in control occurs and we do not offer to repurchase the exchange notes or if we do not repurchase the exchange notes when we are required to, an event of default will occur under the indenture governing the exchange notes, which would also be a default under our senior bank credit facility and other senior subordinated notes. Each of these defaults could have a material adverse effect on us and you.

	You may suffer adverse consequences if you do not exchange existing notes.

      The existing notes that are not exchanged for exchange notes have not been registered with the SEC or in any state. Unless the existing notes are registered, they may only be offered and sold pursuant to an exemption from, or in a transaction that is not subject to, the registration requirements of the Securities Act. Depending upon the percentage of existing notes exchanged for exchange notes, the liquidity of the existing notes may be adversely affected.

	There may not be a liquid market for resale of the exchange notes.

      The exchange notes are new securities for which there currently is no market. We are not currently aware of any person that intends to make a market in the exchange notes. Accordingly, there can be no assurance as to the development or liquidity of any market for the exchange notes. The exchange notes

      Historically, the market for non-investment grade debt has been subject to disruptions that have caused volatility in prices. It is possible that the market for the exchange notes will be subject to disruptions. Any such disruptions may have a negative effect on you, as a holder of the exchange notes, regardless of our prospects and financial performance.

USE OF PROCEEDS

      We will not receive any cash proceeds from the issuance of the exchange notes. In consideration for issuing the exchange notes as contemplated in this prospectus, we will receive in exchange existing notes in like principal amount. The existing notes surrendered in exchange for exchange notes will be retired and canceled and cannot be reissued. Issuance of the exchange notes will not result in a change in our amount of outstanding debt.

THE EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

      We borrowed $200,000,000 pursuant to a senior unsecured credit agreement dated December 8, 2003, and amended and restated as of December 23, 2003. On March 15, 2004, we issued $200,000,000 of our 9.75% Senior Notes due 2010, Series A, in full payment of the $200,000,000 principal amount of loans outstanding under the senior unsecured credit agreement. The existing notes were issued to accredited investors in reliance upon the exemption from registration provided by Rule 506 of Regulation D under the Securities Act and outside the United States in compliance with Regulation S of the Securities Act. In connection with the issuance of the existing notes, we entered into an exchange and registration agreement in which we agreed to:

	•	file with the SEC a registration statement related to the exchange notes;
	•	use our reasonable best efforts to cause the registration statement to become effective under the Securities Act; and
	•	offer to the holders of the existing notes the opportunity to exchange their existing notes for a like principal amount of exchange notes upon the effectiveness of the registration statement.

      A copy of the exchange and registration rights agreement has been filed as an exhibit to the registration statement of which this prospectus is a part.

      Based on existing interpretations of the Securities Act by the staff of the SEC described in several no-action letters issued to unrelated third parties, and subject to the following sentence, we believe that the exchange notes issued in the exchange offer may be offered for resale, resold and otherwise transferred by their holders, other than broker-dealers or our “affiliates,” without further compliance with the registration and prospectus delivery provisions of the Securities Act. However, any holder of existing notes who is an affiliate of ours, who is not acquiring the exchange notes in the ordinary course of such holder’s business or who intends to participate in the exchange offer for the purpose of distributing the exchange notes:

	•	will not be able to rely on the interpretations by the staff of the SEC described in the above-mentioned no-action letters;
	•	will not be able to tender existing notes in the exchange offer; and
	•	must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of the existing notes unless the sale or transfer is made under an exemption from these requirements.

      We do not intend to seek our own no-action letter, and there is no assurance that the staff of the SEC would make a similar determination regarding the exchange notes as it has in these no-action letters to third parties. See “Plan of Distribution.”

      As a result of the filing and effectiveness of the registration statement of which this prospectus is a part, we will not be required to pay an increased interest rate on the existing notes. Following the closing of the exchange offer, holders of existing notes not tendered will not have any further registration rights, and the existing notes will continue to be subject to restrictions on transfer. Accordingly, the liquidity of the market for the existing notes could be adversely affected.

Terms of the Exchange Offer

      Upon the terms and subject to the conditions stated in this prospectus and in the letter of transmittal, we will accept all existing notes properly tendered and not withdrawn prior to 5:00 p.m. New York City time, on the expiration date. After authentication of the exchange notes by the trustee or an authenticating agent, we will issue $1,000 principal amount of exchange notes in exchange for each $1,000 principal amount of outstanding existing notes accepted in the exchange offer. Holders may tender some or all of their existing notes in denominations of $1,000 or any integral multiple of $1,000.

Table of Contents

      If you wish to exchange your existing notes for exchange notes in the exchange offer, you will be required to represent that:

	•	you are not our affiliate, as defined in Rule 405 of the Securities Act;
	•	any exchange notes will be acquired in the ordinary course of your business;
	•	you have no arrangement or understanding with any person to participate in the distribution of the exchange notes;
	•	if you are a broker-dealer that will receive exchange notes for your own account in exchange for existing notes that were acquired as a result of market-making or other trading activities, that you will deliver a prospectus, as required by law, in connection with any resale of those exchange notes.

You will make these representations to us by signing or agreeing to be bound by the letter of transmittal.

      Broker-dealers that are receiving exchange notes for their own account must have acquired the existing notes as a result of market-making or other trading activities in order to participate in the exchange offer. Each broker-dealer that receives exchange notes for its own account under the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the exchange notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be admitting that it is an “underwriter” within the meaning of the Securities Act. We will be required to allow broker-dealers to use this prospectus following the exchange offer in connection with the resale of exchange notes received in exchange for existing notes acquired by broker-dealers for their own account as a result of market-making or other trading activities. If required by applicable securities laws, we will, upon written request, make this prospectus available to any broker-dealer for use in connection with a resale of exchange notes for a period of 90 days after the consummation of the exchange offer. See “Plan of Distribution.”

      The exchange notes will evidence the same debt as the existing notes and will be issued under and entitled to the benefits of the same indenture. The form and terms of the exchange notes are identical in all material respects to the form and terms of the existing notes except that:

	•	the exchange notes will be issued in a transaction registered under the Securities Act;
	•	the exchange notes will not be subject to transfer restrictions and holders of exchange notes will have no registration rights; and
	•	provisions providing for an increase in the stated interest rate on the existing notes if the existing notes are not exchanged for registered exchange notes will be eliminated.

      As of the date of this prospectus, $200,000,000 aggregate principal amount of the existing notes was outstanding. In connection with the issuance of the existing notes, we arranged for the existing notes to be issued and transferable in book-entry form through the facilities of DTC, acting as depositary. The exchange notes will also be issuable and transferable in book-entry form through DTC.

      This prospectus, together with the accompanying letter of transmittal, is initially being sent to all registered holders as of the close of business on [                    ], 2004. We intend to conduct the exchange offer as required by the Exchange Act, and the rules and regulations of the SEC under the Exchange Act, including Rule 14e-1, to the extent applicable.

      Rule 14e-1 describes unlawful tender practices under the Exchange Act. This section requires us, among other things:

	•	to hold our exchange offer open for twenty business days;
	•	to give ten days notice of any change in the terms of this offer; and
	•	to issue a press release in the event of an extension of the exchange offer.

Table of Contents

      The exchange offer is not conditioned upon any minimum aggregate principal amount of existing notes being tendered, and holders of the existing notes do not have any appraisal or dissenters’ rights under the General Corporation Law of the State of Delaware or under the indenture in connection with the exchange offer. No governmental approvals or consents must be received to consummate the exchange offer. We shall be considered to have accepted existing notes tendered according to the procedures in this prospectus when, as and if we have given oral or written notice of acceptance to the exchange agent. See “— Exchange Agent.” The exchange agent will act as agent for the tendering holders for the purpose of receiving exchange notes from us and delivering exchange notes to those holders.

      If any tendered existing notes are not accepted for exchange because of an invalid tender or the occurrence of other events described in this prospectus, the unaccepted existing notes will be credited to the holder’s account at DTC according to the procedures described below or, in the case of existing notes tendered by delivery of certificates, certificates for these unaccepted existing notes will be returned, at our cost, to the tendering holder of the existing notes, as promptly as practicable after the expiration date.

      Holders who tender existing notes in the exchange offer will not be required to pay brokerage commissions or fees or, except as described in the following sentence, transfer taxes related to the exchange of existing notes in the exchange offer. If you instruct us to register exchange notes in the name of, or request that notes not tendered or not accepted in the exchange offer be returned to, a person other than you, you will be responsible for the payment of any applicable transfer tax. We will pay all charges and expenses, other than applicable taxes, in connection with the exchange offer. See “— Solicitation of Tenders; Fees and Expenses.”

      Neither we nor our board of directors makes any recommendation to holders of existing notes as to whether to tender or refrain from tendering all or any portion of their existing notes to the exchange offer. Moreover, no one has been authorized to make any recommendation. Holders of existing notes must make their own decision whether to tender in the exchange offer and, if so, the amount of existing notes to tender after reading this prospectus and the letter of transmittal and consulting with their advisors, if any, based on their own financial position and requirements.

Expiration Date; Extensions; Amendments

      The term “expiration date” shall mean 5:00 p.m., New York City time, on [                    ], 2004 unless we, in our sole discretion, extend the exchange offer, in which case the term “expiration date” shall mean the latest date to which the exchange offer is extended.

      We expressly reserve the right, in our sole discretion:

	•	to delay acceptance of any existing notes or to terminate the exchange offer and to refuse to accept existing notes not previously accepted, if any of the conditions described under “— Conditions” shall have occurred and shall not have been waived by us;
	•	to extend the expiration date of the exchange offer;
	•	to amend the terms of the exchange offer in any manner;
	•	to purchase or make offers for any existing notes that remain outstanding subsequent to the expiration date;
	•	to the extent permitted by applicable law, to purchase existing notes in the open market, in privately negotiated transactions or otherwise.

The terms of the purchases or offers described in the fourth and fifth clauses above may differ from the terms of the exchange offer.

      Any delay in acceptance, termination, extension, or amendment will be followed as promptly as practicable by oral or written notice to the exchange agent and by making a public announcement. If the exchange offer is amended in a manner determined by us to constitute a material change, we will promptly disclose the amendment in a manner reasonably calculated to inform the holders of the amendment.

      Without limiting the manner in which we may choose to make public announcements of any delay in acceptance, termination, extension, or amendment of the exchange offer, we shall have no obligation to publish, advise, or otherwise communicate any public announcement, other than by making a timely press release to a financial news service.

      You are advised that we may extend the exchange offer because some of the holders of the existing notes do not tender on a timely basis. In order to give these noteholders the ability to participate in the exchange and to avoid the significant reduction in liquidity associated with holding an unexchanged note, we may elect to extend the exchange offer.

Interest on the Exchange Notes

      The exchange notes will bear interest from March 15, 2004, the date of issuance of the existing notes that are being tendered in exchange for the exchange notes, or, if later, the most recent date on which interest was paid or provided for on the existing notes surrendered for the exchange notes, at a rate of 9.75% per year. Accordingly, holders of existing notes that are accepted for exchange will not receive interest that is accrued but unpaid on the existing notes at the time of tender. Interest on the exchange notes will be payable quarterly on each March 31st, June 30th, September 30th and December 31st, commencing on June 30, 2004.

Procedures for Tendering

      Only a holder may tender its existing notes in the exchange offer. Any beneficial owner whose existing notes are registered in the name of his broker, dealer, commercial bank, trust company or other nominee or are held in book-entry form and who wishes to tender should contact the registered holder promptly and instruct the registered holder to tender on his behalf. If the beneficial owner wishes to tender on his own behalf, the beneficial owner must, prior to completing and executing the letter of transmittal and delivering his existing notes, either make appropriate arrangements to register ownership of the existing notes in the owner’s name or obtain a properly completed bond power from the registered holder. The transfer of record ownership may take considerable time and may not be completed prior to the expiration time.

      The tender by a holder will constitute an agreement between the holder, us and the exchange agent according to the terms and subject to the conditions described in this prospectus and in the letter of transmittal.

      A holder who desires to tender existing notes and who cannot comply with the procedures set forth herein for tender on a timely basis or whose existing notes are not immediately available must comply with the procedures for guaranteed delivery set forth below.

      The method of delivery of existing notes and the letter of transmittal and all other required documents to the exchange agent is at the election and risk of the holders. Delivery of such documents will be deemed made only when actually received by the exchange agent or deemed received under the ATOP procedures described below. In all cases, sufficient time should be allowed to assure delivery to the exchange agent prior to the expiration date. No letter of transmittal or existing notes should be sent to us. Holders may also request that their respective brokers, dealers, commercial banks, trust companies or nominees effect the tender for holders in each case as described in this prospectus and in the letter of transmittal.

	Existing Notes Held in Book-Entry Form

      We understand that the exchange agent will make a request promptly after the date of the prospectus to establish accounts for the existing notes at DTC for the purpose of facilitating the exchange offer, and subject to their establishment, any financial institution that is a participant in DTC may make book-entry delivery of existing notes by causing DTC to transfer the existing notes into the exchange agent’s account for the existing notes using DTC’s procedures for transfer.

Table of Contents

      The exchange agent and DTC have confirmed that the exchange offer is eligible for DTC’s Automated Tender Offer Program (ATOP). Accordingly, DTC participants may, instead of physically completing and signing the letter of transmittal and delivering it to the exchange agent, electronically transmit their acceptance of the exchange offer by causing DTC to transfer existing notes held in book-entry form to the exchange agent in accordance with DTC’s ATOP procedures for transfer. DTC will then send a book-entry confirmation, including an agent’s message to the exchange agent.

      The term “agent’s message” means a message transmitted by DTC, received by the exchange agent and forming part of the book-entry confirmation, which states that DTC has received an express acknowledgment from the participant in DTC tendering existing notes that are the subject of that book-entry confirmation that the participant has received and agrees to be bound by the terms of the letter of transmittal, and that we may enforce such agreement against such participant. If you use ATOP procedures to tender existing notes you will not be required to deliver a letter of transmittal to the exchange agent, but you will be bound by its terms just as if you had signed it.

      If you desire to tender existing notes held in book-entry form with DTC, the exchange agent must receive, prior to 5:00 p.m. New York City time on the expiration date, at its address set forth in this prospectus, a confirmation of book-entry transfer of the existing notes into the exchange agent’s account at DTC, which is referred to in this prospectus as a “book-entry confirmation,” and an agent’s message transmitted pursuant to DTC’s Automated Tender Offer Program. In lieu of transmitting an agent’s message pursuant to DTC’s ATOP procedures, you may deliver to the exchange agent, prior to 5:00 p.m. New York City time on the expiration date, at the address set forth in the prospectus, a properly completed and validly executed letter of transmittal, or manually signed facsimile thereof, together with any signature guarantees and other documents required by the instructions in the letter of transmittal.

	Existing Notes Held in Certificated Form

      For a holder to validly tender existing notes held in physical form, the exchange agent must receive, prior to 5:00 p.m. New York city time on the expiration date, at its address set forth in this prospectus:

	•	a properly completed and validly executed letter of transmittal, or a manually signed facsimile thereof, together with any signature guarantees and any other documents required by the instructions to the letter of transmittal, and
	•	certificates for tendered existing notes.

	Signatures

      Signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc. or a commercial bank or trust company having an office or correspondent in the United States or an “eligible guarantor institution” within the meaning of Rule 17Ad-15 under the Exchange Act, unless the existing notes tendered with the letter of transmittal are tendered:

	•	by a registered holder who has not requested that Exchange Notes or certificates representing Existing Notes not being tendered be issued to a person other than the registered holder, sent to an address other than that of a registered holder or credited to different account maintained at DTC; or
	•	for the account of an institution eligible to guarantee signatures.

      If the letter of transmittal is signed by a person other than the registered holder or DTC participant who is listed as the owner, the existing notes must be endorsed or accompanied by appropriate bond powers which authorize the person to tender the existing notes on behalf of the registered holder or DTC participant who is listed as the owner, in either case signed as the name of the registered holder(s) who appears on the existing notes or the DTC participant who is listed as the owner. If the letter of transmittal or any existing notes or bond powers are signed or endorsed by trustees, executors, administrators,

	Determinations of Validity

      All questions as to the validity, form, eligibility, including time of receipt, acceptance and withdrawal of the tendered existing notes will be determined by us in our sole discretion. This determination will be final and binding. We reserve the absolute right to reject any and all existing notes not properly tendered or any existing notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any irregularities or conditions of tender as to particular existing notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of existing notes must be cured within the time we shall determine. Although we intend to notify holders of defects or irregularities related to tenders of existing notes, neither we, the exchange agent nor any other person shall be under any duty to give notification of defects or irregularities related to tenders of existing notes nor shall any of them incur liability for failure to give notification. Tenders of existing notes will not be considered to have been made until the irregularities have been cured or waived. Any existing notes received by the exchange agent that we determine are not properly tendered or the tender of which is otherwise rejected by us and as to which the defects or irregularities have not been cured or waived by us will be returned by the exchange agent to the tendering holder unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration date.

Any existing notes so withdrawn will be judged not to have been tendered according to the procedures in this prospectus for purposes of the exchange offer, and no exchange notes will be issued in exchange for those existing notes unless the existing notes so withdrawn are validly retendered. Any existing notes that have been tendered but are not accepted for exchange will be returned to the holder of the existing notes without cost to the holder or, in the case of existing notes tendered by book-entry transfer into the holder’s account at DTC according to the procedures described above. This return or crediting will take place as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly

Conditions

      The exchange offer is subject only to the following conditions:

	•	the compliance of the exchange offer with securities laws;
	•	the tender of the existing notes;
	•	the representation by the holders of the existing notes that they are not our affiliate, that the exchange notes they will receive are being acquired by them in the ordinary course of their business and that at the time the exchange offer is completed the holder had no plan to participate in the distribution of the exchange notes; and

Exchange Agent

      American Stock Transfer & Trust Company, the trustee under the indenture, has been appointed as exchange agent for the exchange offer. In this capacity, the exchange agent has no fiduciary duties and will be acting solely on the basis of our directions. Requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal, and requests for the notice of guaranteed delivery should be directed to the exchange agent. You should send certificates for existing notes, letters of transmittal and any other required documents to the exchange agent addressed to:

American Stock Transfer & Trust Company

Facsimile Transmission: (718) 234-5001

      Delivery of the letter of transmittal to an address other than as listed above or transmission of instructions via facsimile other than as described above does not constitute a valid delivery of the letter of transmittal.

Solicitation of Tenders; Fees and Expenses

      We will bear the expenses of requesting that holders of existing notes tender those notes for exchange notes. The principal solicitation under the exchange offer is being made by mail. Additional solicitations may be made by our officers and regular employees and our affiliates in person, by telegraph, telephone or telecopier.

      We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to brokers, dealers or other persons soliciting acceptances of the exchange offer. We, however, will pay the exchange agent reasonable and customary fees for its services and will reimburse the exchange agent for its reasonable out-of-pocket costs and expenses in connection with the exchange offer and will indemnify the exchange agent for all losses and claims incurred by it as a result of the exchange offer. We may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this prospectus, letters of transmittal and related documents to the beneficial owners of the existing notes and in handling or forwarding tenders for exchange.

Table of Contents

      We will pay the expenses to be incurred in connection with the exchange offer, including fees and expenses of the exchange agent and trustee, SEC registration fees, and accounting and legal fees, printing costs, transfer taxes and related fees and expenses.

      You will not be obligated to pay any transfer tax in connection with the exchange, except if you instruct us to register exchange notes in the name of, or request that notes not tendered or not accepted in the exchange offer be returned to, a person other than you, you will be responsible for the payment of any applicable transfer tax.

Accounting Treatment

      The exchange notes will be recorded at the same carrying value as the existing notes, as reflected in our accounting records on the date of the exchange. Accordingly, no gain or loss for accounting purposes will be recognized by us upon the closing of the exchange offer. We will amortize the expenses of the exchange offer over the term of the exchange notes.

Federal Income Tax Consequences

      The following discussion generally summarizes the principal U.S. federal income tax consequences of the exchange of existing notes for exchange notes. This discussion is based upon the U.S. federal income tax laws in effect and available on the date of this prospectus, including the Internal Revenue Code of 1986, as amended, the related Treasury Regulations and judicial and administrative interpretations of the Internal Revenue Code and Treasury Regulations. All of these laws are subject to change, possibly retroactively, or different interpretation. We cannot assure you that the Internal Revenue Service will not challenge one or more of the tax consequences described in this prospectus. We have not obtained, nor do we intend to obtain, a ruling from the Internal Revenue Service with respect to the U.S. federal income tax consequences of the exchange offer. This discussion does not purport to address all aspects of U.S. federal income taxation that may be relevant to you in light of your specific circumstances, or if you are subject to special treatment under the Internal Revenue Code. This discussion also does not address the effect of any applicable U.S. federal estate and gift tax laws or state, local or foreign tax laws.

      The exchange of existing notes for exchange notes pursuant to the exchange offer should not be a taxable event for U.S. federal income tax purposes. You should not recognize gain or loss upon the receipt of exchange notes. If you are not exempt from U.S. federal income tax you should be subject to such tax on the same amount, in the same manner and at the same time as you would have been as a result of holding the existing notes. If you are a cash-basis holder who is exchanging existing notes for exchange notes, you should not recognize in income any accrued and unpaid interest on the existing notes by reason of the exchange. The basis and holding period of the exchange notes will be the same as the basis and holding period of the corresponding existing notes.

      This description is included in this prospectus for general information only. Accordingly, you should consult with your own tax advisor concerning the U.S. federal income tax consequences of the exchange offer with respect to your particular situation, including the application and effect of state, local and foreign income and other tax laws.

Participation in the Exchange Offer; Untendered Notes

      Participation in the exchange offer is voluntary. Holders of the existing notes are urged to consult their financial and tax advisors in making their own decisions on what action to take.

      As a result of the making of, and upon acceptance for exchange of all existing notes tendered under the terms of, this exchange offer, we will have fulfilled a covenant contained in the terms of the exchange and registration rights agreement. Holders of the existing notes who do not tender in the exchange offer will continue to hold their existing notes and will be entitled to all the rights, and subject to the limitations, applicable to the existing notes under the indenture. Holders of existing notes will no longer be entitled to any rights under the exchange and registration rights agreement that by their terms terminate or

Table of Contents

      We may in the future seek to acquire untendered existing notes in the open market or through privately negotiated transactions, through subsequent exchange offers or otherwise. We intend to make any acquisitions of existing notes following the applicable requirements of the Exchange Act, and the rules and regulations of the SEC under the Exchange Act, including Rule 14e-1, to the extent applicable. We have no present plan to acquire any existing notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any existing notes that are not tendered in the exchange offer.

DESCRIPTION OF THE EXCHANGE NOTES

      We will issue the exchange notes under an Indenture dated March 15, 2004 (the “Indenture”) among us, the Subsidiary Guarantors and American Stock Transfer & Trust Company, as trustee (the “Trustee”). The terms of the exchange notes include those expressly set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Indenture is limited in aggregate principal amount to $200.0 million. We will issue a maximum principal amount of $200,000,000 of exchange notes in exchange for the existing notes in the exchange offer.

      This Description of Notes is intended to be a useful overview of the material provisions of the exchange notes and the Indenture. Since this description is only a summary, you should refer to the Indenture for a complete description of our obligations and your rights.

      You will find the definitions of capitalized terms used in this description under the heading “Certain Definitions.”

      For purposes of this description, references to “the Company,” “we,” “our,” and “us” refer only to Callon Petroleum Company and not to its subsidiaries. The exchange notes and the existing notes will be treated as a single class for all purposes of the indenture. References in this section to the “Securities” includes both the exchange notes and the existing notes.

	Payments on the Notes; Paying Agent and Registrar

      Payments of principal on, premium if any, and interest on Securities represented by a Global Security will be made by the transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a Definitive Security by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Securities may also be made, in the case of a Holder of a least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment, or such other date as the Trustee may accept in its discretion.

      The Company will maintain in The City of New York, an office or agency where the Securities may be presented or surrendered for payment (“Paying Agent”), where, if applicable, the Securities may be surrendered for registration of transfer or exchange (“Registrar”) and where notices and demands to or upon the Company in respect of the Securities and the Indenture may be served. The principal corporate trust office of the Trustee, or if the Trustee’s principal corporate trust office is not located in The City of New York, any other office or agency maintained by the Trustee in The City of New York (the “Corporate Trust Office”), shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company will give prompt written notice to the Trustee of any change in the location of any such office or agency.

	Transfer and Exchange

      A Holder of Securities may transfer or exchange notes at the office of the Registrar in accordance with the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by the Company, the Trustee or the Registrar for any registration of transfer or exchange of Securities, but the Company may require a Holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted by the Indenture. The Company is not required to transfer or exchange any note selected for redemption. Also, the Company is not required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed.

      The registered Holder of a Security will be treated as the owner of it for all purposes.

Optional Redemption

      The Securities will not be redeemable at the option of the Company prior to December 8, 2007. On and after such date, the Securities will be redeemable, at the Company’s option, in whole or in part, at any time upon not less than 30 nor more than 60 days prior notice mailed by first class mail to each Holder’s registered address, at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date):

      If redeemed during the 12 month period commencing on December 8 of the years set forth below:

		Redemption
Period		Price
2007			105.0	%
2008			103.0	%
2009			101.0	%

      In the case of any partial redemption, selection of the Securities for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed or, if the Securities are not listed, then on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate, although no Securities

Ranking

      The Securities will be general unsecured obligations of the Company that rank senior in right of payments to all existing and future Debt that is expressly subordinated in right of payment to the Securities. The Securities will rank equally in right of payment with all existing and future liabilities of the Company that are not so subordinated. The Securities will effectively rank junior to any secured Debt of the Company or its Subsidiary Guarantors, to the extent of the assets securing such Debt. In the event of bankruptcy, liquidation, reorganization or other winding up of the Company, the assets of the Company that secure secured Debt will be available to pay obligations on the Securities only after all Debt under such secured Debt has been repaid in full from such assets. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all of the Securities then outstanding. The Subsidiary Guarantees of the Securities will have a similar ranking with respect to secured and unsecured senior Debt of the Subsidiary Guarantors as the Securities do with respect to secured and unsecured senior Debt of the Company as well as with respect to any unsecured obligations expressly subordinated in right of payment to the Subsidiary Guarantees.

Subsidiary Guarantees

      The Subsidiary Guarantors will, jointly and severally, unconditionally guarantee, on a senior unsecured basis, the Company’s obligations under the Securities and all obligations under the Indenture. Each Subsidiary Guarantee will rank equally with all other senior Debt of that Subsidiary Guarantor. Unsecured Debt of the Subsidiary Guarantors is not deemed to be subordinate or junior to secured Debt merely because it is unsecured.

      The obligations of each Subsidiary Guarantor under its Subsidiary Guarantee will be limited as necessary to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law.

      In the event a Subsidiary Guarantor is sold or disposed of (whether by merger, consolidation, the sale of its Capital Stock or the sale of its capital stock or the sale of all or substantially all of its assets (other than by lease)) and whether or not the Subsidiary Guarantor is the surviving corporation in such transaction to a Person which is not the Company or a Restricted Subsidiary of the Company, such Subsidiary Guarantor will be released from its obligations under its Subsidiary Guarantee if:

      (1) the sale or other disposition is in compliance with the Indenture, including the covenants “— Sales of Property” and “— Issuance and Sale of Capital Stock;” and

      (2) all the obligations of such Subsidiary Guarantor under the Senior Secured Credit Facility and related documentation and any other agreements relating to any other indebtedness of the Company or its Restricted Subsidiaries terminate upon consummation of such transaction.

      In addition, a Subsidiary Guarantor will be released from its obligations under the Indenture and the Subsidiary Guarantee if the Company designates such Subsidiary as an Unrestricted Subsidiary and such designation complies with the other applicable provisions of the Indenture.

Change in Control

      If a Change in Control occurs, each registered Holder of Securities will have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s

35

---

Table of Contents

      Within 30 days following any Change in Control, the Company will mail a notice (the “Change in Control Offer”) to each registered Holder with a copy to the Trustee stating:

      (1) that a Change in Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount of such Securities plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant interest payment date) (the “Change in Control Payment”);

      (2) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the “Change in Control Payment Date”); and

      (3) the procedures determined by the Company, consistent with the Indenture, that a Holder must follow in order to have its Securities repurchased.

      On the Change in Control Payment Date, the Company will, to the extent lawful:

      (1) accept for payment all Securities or portions of Securities (in integral multiples of $1,000) properly tendered under the Change in Control Offer;

      (2) deposit with the Paying Agent an amount equal to the Change in Control Payment in respect of all Securities or portions of Securities so tendered; and

      (3) deliver or cause to be delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions of Securities being purchased by the Company.

      The paying agent will promptly mail to each Holder of Securities so tendered the Change in Control Payment for such Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple of $1,000.

      If the Change in Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender pursuant to the Change in Control Offer.

      The Change in Control provisions described above will be applicable whether or not any other provisions of the Indenture are applicable. Except as described above with respect to a Change in Control, the Indenture does not contain provisions that permit the Holders to require that the Company repurchase or redeem the Securities in the event of a takeover, recapitalization or similar transaction.

      The Company will not be required to make a Change in Control Offer upon a Change in Control if a third party makes the Change in Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change in Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Change in Control Offer.

      The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this covenant. To the extent that the provisions of any securities laws or regulations conflict with provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described in the Indenture by virtue of the conflict.

Table of Contents

      The Company’s ability to repurchase Securities pursuant to a Change in Control Offer may be limited by a number of factors. The occurrence of certain of the events that constitute a Change in Control would constitute a default under the Senior Secured Credit Facility. In addition, certain events that may constitute a Change in Control under the Senior Secured Credit Facility and cause a default thereunder may not constitute a Change in Control under the Indenture. Future Debt of the Company and its Subsidiaries may also contain prohibitions of certain events that would constitute a Change in Control or require such Debt to be repurchased upon a Change in Control. Moreover, the exercise by the Holders of their right to require the Company to repurchase the Securities could cause a default under such Debt, even if the Change in Control itself does not, due to the financial effect of such repurchase on the Company. Finally, the Company’s ability to pay cash to the Holders upon a repurchase may be limited by the Company’s then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

      Even if sufficient funds were otherwise available, the terms of the Senior Secured Credit Facility (and other Debt may) prohibits the Company’s prepayment of Securities before their scheduled maturity. Consequently, if the Company is not able to prepay the Debt under the Senior Secured Credit Facility and any such other Debt containing similar restrictions or obtain requisite consents, as described above, the Company will be unable to fulfill its repurchase obligations if Holders of Securities exercise their repurchase rights following a Change in Control, resulting in a default under the Indenture. A default under the Indenture may result in a cross-default under the Senior Secured Credit Facility.

      The Change in Control provisions described above may deter certain mergers, tender offers and other takeover attempts involving the Company by increasing the capital required to effectuate such transactions.

	Sale or Discount of Receivables

      Neither the Company nor any Restricted Subsidiary will discount or sell (with or without recourse) any of its Securities receivable or accounts receivable other than settlement of any past due accounts in the ordinary course of business and in accordance with prudent commercial practices.

	Sale of Property

      The Company shall not, and shall not permit any Restricted Subsidiary to, sell, assign, convey or otherwise transfer any Property unless (i) consideration equal to the fair market value of the Property sold is received, (ii) the sale is an arm’s length transaction; (iii) all of the consideration received consists of cash, Cash Equivalents, liquid securities or Exchanged Properties (“Permitted Consideration”); provided, however, that the Company and its Restricted Subsidiaries may receive Property that does not constitute Permitted Consideration, so long as the aggregate fair market value of all Property received pursuant to this proviso shall not exceed 10.0% of Adjusted Consolidated Net Tangible Assets, as determined by the Company’s Board of Directors.

      Within 365 days following the receipt of Net Available Cash, an amount equal to 100% of the Net Available Cash from such Asset Disposition shall be applied by the Company or such Restricted Subsidiary, as the case may be:

      (1) to apply all or any of the Net Available Cash therefrom to repay indebtedness under the Senior Secured Credit Facility, or

      (2) invest all or any part of the Net Available Cash in Property that will be used in the oil and gas business of the Company or its Restricted Subsidiaries.

      Any Net Available Cash from Asset Dispositions that are not applied or invested as provided in the preceding paragraph will be deemed to constitute “Excess Proceeds.” On the 366th day after an Asset Disposition, if the aggregate amount of Excess Proceeds exceeds $5,000,000.00, the Company will be required to make an offer (“Asset Disposition Offer”) to all Holders of Securities and to the extent required by the terms of other Senior Indebtedness, to all Holders of other Senior Indebtedness outstanding with similar provisions requiring the Company to make an offer to purchase such Senior Indebtedness with the proceeds from any Asset Disposition (“Pari Passu Notes”), to purchase the maximum principal amount of Securities and any such Pari Passu Notes to which the Asset Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Securities and Pari Passu Notes plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth herein or in the agreements governing the Pari Passu Notes, as applicable. To the extent that the aggregate amount of Securities and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes, subject to the other covenants contained herein. If the aggregate principal amount of Securities surrendered by Holders thereof and other Pari Passu Notes surrendered by Holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Company shall select the Securities and Pari Passu Notes to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Securities and Pari Passu Notes. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

      The Asset Disposition Offer will remain open for a period of twenty (20) Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five (5) Business Days after the termination of the Asset

      Any accrued and unpaid interest will be paid to the Person in whose name a Security is registered at the close of business on such date, and no additional interest will be payable to Holders of the Securities who tender Securities pursuant to the Asset Disposition Offer.

      On or before the Asset Disposition Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Securities and Pari Passu Notes or portions of Securities and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Securities and Pari Passu Notes so validly tendered and not properly withdrawn. The Company will deliver all certificates and Securities required, if any, by the Indenture or the agreements governing the Pari Passu Notes. The Company will promptly (but in any case not later than the Asset Disposition Purchase Date) mail or deliver to each tendering Holder of Securities or Holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Securities or Pari Passu Notes so validly tendered and not properly withdrawn by such Holder or lender, as the case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Security and will deliver such new Security to such Holder, in a principal amount equal to any unpurchased portion of the Security surrendered. In addition, the Company will take any and all other actions required by the agreements governing the Pari Passu Notes. Any Security not so accepted will be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date.

      For the purposes of this covenant, the following will be deemed to be cash:

      (1) the assumption by the transferee of Debt (other than Subordinated Debt or Disqualified Stock) of the Company or Debt (other than Preferred Stock) of any Restricted Subsidiary of the Company and the release of the Company or such Restricted Subsidiary from all liability on such Debt in connection with such Asset Disposition (in which case the Company will, without further action, be deemed to have applied such deemed cash to Debt in accordance with the second paragraph of this covenant above); and

      (2) securities, notes or other obligations received by the Company or any Restricted Subsidiary of the Company from the transferee that are promptly converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents.

      The Company will comply, to the extent applicable, with the requirements of securities laws or regulations in connection with the repurchase of Securities pursuant to this Agreement. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Indenture by virtue of complying with such securities laws and regulations.

     Transactions with Affiliates

      Neither the Company nor any Restricted Subsidiary will enter into any transaction, including, without limitation, any purchase, sale, lease or exchange of Property or the rendering of any service, with any Affiliate unless such transaction is otherwise permitted under the Indenture, is in the ordinary course of its business and is upon fair and reasonable terms no less favorable to it than it would obtain in a comparable arm’s length transaction with a Person not an Affiliate; provided, however, that notwithstanding the provisions of this covenant, the Company may engage in the Permitted Medusa Transaction.

In the event that the Company is not permitted to file such reports, documents and information with the Commission pursuant to the Exchange Act, the Company will nevertheless provide such Exchange Act information to the Trustee and the Holders of the Securities as if the Company were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified therein.

      The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture.

      After the Issue Date, the Company will cause each Restricted Subsidiary, other than a Foreign Subsidiary, created or acquired by the Company or one or more of its Restricted Subsidiaries to execute and deliver to the Trustee a Subsidiary Guarantee pursuant to which such Subsidiary Guarantor will unconditionally Guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest on the Securities on a senior basis.

      (7) a judgment or judgments for the payment of money in excess of $10,000,000 in the aggregate (net of any amounts that a reputable and creditworthy insurance company has acknowledged liability for in writing) shall be rendered by a court against the Company or any Restricted Subsidiary and the same shall not be discharged (or provision shall not be made for such discharge), or a stay of execution thereof shall not be procured, within sixty (60) days from the date of entry thereof and the Company or such Subsidiary shall not, within said period of sixty (60) days, or such longer period during which execution of the same shall have been stayed, appeal therefrom and cause the execution thereof to be stayed during such appeal; or

      (8) any Subsidiary takes, suffers or permits to exist any of the events or conditions referred to in clauses (4), (5), (6) or (7), and such event or condition has a Material Adverse Effect.

      Notwithstanding the foregoing, a Default under clause (3) above will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company of the Default and the Company does not cure such Default within the time specified in said clause (3) after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

      If an Event of Default (other than an Event of Default specified in clause (5) or (6) above) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, on all the Securities to be due and payable. Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest will be due and payable immediately. In the event of a declaration of acceleration because an Event of Default set forth clause (2) above has occurred and is continuing, the declaration of acceleration shall be automatically annulled if the event of default or payment default triggering such Event of Default pursuant to clause (2) shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the Holders of the relevant Debt within 20 days after the declaration of acceleration with respect thereto and if (a) the annulment of the acceleration of the Securities would not conflict with any judgment or decree of a court of competent jurisdiction and (b) all existing Events of Default, except nonpayment of principal, premium or interest on the Securities that became due solely because of such acceleration, have been cured or waived. No such rescission shall affect any subsequent Default or Event of Default or impair any right consequent thereto. If an Event of Default described in clause (5) or (6) above occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

      The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may:

      (1) waive, by their consent (including, without limitation consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities), an existing Default or Event of Default and its consequences, except (a) a Default or Event of Default in the payment of the principal of, or premium,

      (2) rescind any such acceleration with respect to the Securities and its consequences if (a) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (b) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Securities that have become due solely by such declaration of acceleration, have been cured or waived.

When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

      Subject to the provisions of the Indenture relating to the duties of the Trustee, if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Securities unless:

      (1) such Holder has previously given the Trustee notice that an Event of Default is continuing;

      (2) Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee to pursue the remedy;

      (3) such Holder or Holders offer the Trustee reasonable security or indemnity against any loss, liability or expense;

      (4) the Trustee does not comply with such request within 60 days after the receipt of the request and the offer of security or indemnity; and

      (5) the Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

      Subject to certain restrictions, the Holders of a majority in principal amount of the outstanding Securities are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Indenture provides that in the event an Event of Default has occurred and is continuing, the Trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability, but may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action under the Indenture, the Trustee will be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

      The Indenture provides that if a Default occurs and is continuing and is known to the Trustee, the Trustee must mail to each Holder notice of the Default or Event of Default within 45 days after it occurs. Except in the case of a Default or Event of Default in the payment of principal of, premium, if any, or interest on any Security, the Trustee may withhold notice if and so long as a committee of trust officers of the Trustee in good faith determines that withholding notice is in the interests of the Holders. In addition, the Company is required to deliver to the Trustee, promptly after the end of each Fiscal Year, a certificate indicating whether the signers thereof know of any Default or Event of Default that occurred during the previous year. The Company also is required to deliver to the Trustee, promptly after the occurrence thereof, written notice of any Default or Event of Default, their status and what action the Company is taking or proposes to take in respect thereof.

Amendments and Waivers

      Subject to certain exceptions, the Indenture may be amended with the consent of the Holders of at least 75% in principal amount of the Securities then outstanding (including without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). However, without the consent of each Holder of an outstanding Security affected, no amendment may, among other things:

      (1) reduce the amount of Securities whose Holders must consent to an amendment;

      (2) reduce the stated rate of or extend the stated time for payment of interest on any Security;

      (3) reduce the principal of or extend the maturity of any Security;

      (4) reduce the premium payable upon the redemption or repurchase of any Security or change the time at which any Security may be redeemed or repurchased as described above under “Optional Redemption,” “Change in Control,” or “Certain Covenants — Sale of Property,” or any similar provision, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

      (5) make any Security payable in money other than that stated in the Security;

      (6) impair the right of any Holder to receive payment of, premium, if any, principal of and interest on such Holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities; or

      (7) make any change in the amendment provisions which require each Holder’s consent or in the waiver provisions.

      Without the consent of any Holder, the Company and the Trustee may amend the Indenture to:

      (1) cure any ambiguity, omission, defect or inconsistency;

      (2) provide for the assumption by a successor corporation, partnership, trust or limited liability company of the obligations of the Company under the Indenture;

      (3) provide for uncertificated Securities in addition to or in place of certificated Securities (provided that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code);

      (4) add Subsidiary Guarantees with respect to the Securities or release a Subsidiary Guarantor upon its sale or disposition, or designation as an Unrestricted Subsidiary; provided, however, that the designation, or sale or disposition is in accord with the applicable provisions of the Indenture;

      (5) secure the Securities;

      (6) add to the covenants of the Company for the benefit of the Holders or surrender any right or power conferred upon the Company;

      (7) make any change that does not adversely affect the rights of any Holder; or

      (8) comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act.

      The consent of the Holders is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under the Indenture becomes effective, the Company is required to mail to the Holders a notice briefly describing such amendment. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the amendment.

Defeasance

      The Company at any time may terminate all its obligations under the Securities and the Indenture (“legal defeasance”), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the Securities, to replace mutilated, destroyed, lost or stolen Securities and to maintain a registrar and paying agent in respect of the Securities. If the Company exercises its legal defeasance option, the Subsidiary Guarantees in effect at such time will terminate.

      The Company at any time may terminate its obligations described under “Merger and Consolidation,” the covenants described under “Certain Covenants”, and the operation of the cross-default upon a payment default, cross acceleration provisions, the bankruptcy provisions and the judgment default provisions with respect to Subsidiaries described under “Events of Default”above (“covenant defeasance”).

      The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect to the Securities. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in clause (2), (3), or (8), or (with respect only to Subsidiaries), (4), (5) or (6) under “Events of Default” above.

      In order to exercise either defeasance option, the Company must irrevocably deposit in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Securities to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the Trustee of an Opinion of Counsel (subject to customary exceptions and exclusions) to the effect that Holders of the Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred. In the case of legal defeasance only, such Opinion of Counsel must be based on a ruling of the Internal Revenue Service or other change in applicable Federal income tax law.

No Personal Liability of Directors, Officers, Employees and Stockholders

      No director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company under the Securities, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

Concerning the Trustee

      American Stock Transfer & Trust Company is the Trustee under the Indenture and has been appointed by the Company as Registrar and Paying Agent with regard to the Securities.

Governing Law

      The Indenture provides that it and the Securities will be governed by, and construed in accordance with, the laws of the State of New York.

Book-Entry, Delivery and Form

      The existing notes were, and any exchange notes issued in exchange for existing notes tendered pursuant to The Depository Trust Company’s Automated Tender Offer Program will be, issued in the form of one or more fully registered global certificates. Each global certificate will be deposited with the trustee

Table of Contents

      Except as set forth below, a global certificate may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

      The descriptions of the operations and procedures of DTC set forth below are provided solely as a matter of convenience. These operations and procedures are solely within the control of these settlement systems and are subject to change by them from time to time. We do not take any responsibility for these operations or procedures, and lenders under the credit agreement acquiring notes issued in repayment of their loans are urged to contact the relevant system or its participants directly to discuss these matters.

      DTC has advised us that it is:

	•	a limited purpose trust company organized under the laws of the State of New York;
	•	a “banking organization” within the meaning of the New York Banking Law;
	•	a member of the Federal Reserve System;
	•	a “clearing corporation” within the meaning of the New York Uniform Commercial Code, as amended; and
	•	a “clearing agency” registered under Section 17A of the Securities Exchange Act of 1934.

      DTC was created to hold securities for its participants and facilitates the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants, which eliminates the need for physical transfer and delivery of certificates. DTC’s participants include securities brokers and dealers, including banks and trust companies; clearing corporations and some other organizations. Indirect access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a participant in DTC, either directly or indirectly. Holders of existing notes that are exchanging existing notes for exchange notes who are not DTC participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants in DTC.

      We expect that pursuant to procedures established by DTC:

	•	upon our issuance of the exchange notes, DTC will credit the accounts of participants designated by the exchange agent with the principal amount of the exchange notes exchanged for existing notes, and
	•	ownership of beneficial interests in any global note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC, with respect to the interests of participants in DTC, and the records of participants and indirect participants, with respect to the interests of persons other than participants in DTC.

      The laws of some jurisdictions may require that some purchasers of securities take physical delivery of the securities in definitive form. Accordingly, the ability to transfer interests in the exchange notes represented by a global note to these persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in exchanges notes represented by a global note to pledge or transfer that interest to persons or entities that do not participate in DTC’s system, or to otherwise take actions in respect of that interest, may be affected by the lack of a physical definitive security in respect of the interest.

      So long as DTC or its nominee is the registered owner of a global note, DTC or the nominee, as the case may be, will be considered the sole owner or Holder of the exchange notes represented by the global

50

Table of Contents

	•	will not be entitled to have notes represented by the global note registered in their names;
	•	will not receive or be entitled to receive physical delivery of certificated notes; and
	•	will not be considered the owners or Holders of the notes under the indenture for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee under the indenture.

      Accordingly, each Holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if the Holder is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the Holder owns its interest, to exercise any rights of a Holder of notes under the indenture or the global note. We understand that under existing industry practice, if we request any action of Holders of notes, or a Holder that is an owner of a beneficial interest in a global note desires to take any action that DTC, as the Holder of the global note, is entitled to take, then DTC would authorize its participants to take the action and the participants would authorize Holders owning through participants to take the action or would otherwise act upon the instruction of such Holders. Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in global notes held by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the notes.

      As long as the exchange notes are represented by a global note, DTC’s nominee will be the holder of the exchange notes and therefore will be the only entity that can exercise a right to repayment or repurchase of the exchange notes. See “— Repurchase at the Option of Holders — Change of Control” and “— Asset Sales.” Notice by participants or indirect participants or by owners of beneficial interests in a global certificate held through such participants or indirect participants of the exercise of the option to elect repayment of beneficial interests in exchange notes represented by a global note must be transmitted to DTC in accordance with its procedures on a form required by DTC and provided to participants. In order to ensure that DTC’s nominee will timely exercise a right to repayment with respect to a particular exchange note, the beneficial owner of such exchange note must instruct the broker or other participant or indirect participant through which it holds an interest in such exchange note to notify DTC of its desire to exercise a right to repayment. Different firms have different cut-off times for accepting instructions from their customers and, accordingly, each beneficial owner should consult the broker or other participant or indirect participant through which it holds an interest in a exchange note in order to ascertain the cutoff time by which such an instruction must be given in order for timely notice to be delivered to DTC.

      We will not be liable for any delay in delivery of notices of the exercise of the option to elect repayment.

      Payments with respect to the principal of, and premium, if any, liquidated damages, if any, and interest on, any notes represented by a global note registered in the name of DTC or its nominee on the applicable record date will be payable by the trustee to or at the direction of DTC or its nominee in its capacity as the registered Holder of the global note representing those notes under the indenture. Under the terms of the indenture, we and the trustee may treat the persons in whose names the notes, including the global notes, are registered as the owners of the notes for the purpose of receiving payment on the notes and for any and all other purposes whatsoever. Accordingly, neither we nor the trustee has or will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global note, including principal, premium, if any, liquidated damages, if any, and interest. Payments by the participants and the indirect participants in DTC to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of the participants or the indirect participants and DTC.

Certificated Notes

      If:

	•	DTC notifies us that it is at any time unwilling or unable to continue as a depositary or DTC ceases to be registered as a clearing agency under the Securities Exchange Act of 1934 and a successor depositary is not appointed within 90 days of such notice or cessation;
	•	we, at our option, notify the trustee in writing that we elect to cause the issuance of notes in definitive form under the indenture; or
	•	upon the occurrence of some other events as provided in the indenture,

then, upon surrender by DTC of the global notes, certificated notes will be issued to each person that DTC identifies as the beneficial owner of the notes represented by the global notes. Upon the issuance of certificated notes, the trustee is required to register the certificated notes in the name of that person or persons, or their nominee, and cause the certificated notes to be delivered thereto.

      Neither we nor the trustee will be liable for any delay by DTC or any participant or indirect participant in DTC in identifying the beneficial owners of the related notes and each of those persons may conclusively rely on, and will be protected in relying on, instructions from DTC for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the notes to be issued.

FEDERAL INCOME TAX CONSIDERATIONS

      The following is a discussion of the material U.S. federal income tax consequences of the ownership and disposition of the notes and represents the opinion of our counsel, Haynes and Boone, LLP, as, to these matters. Unless otherwise stated, this discussion is limited to the tax consequences to those persons who purchase the notes from the initial purchasers and who hold the notes as capital assets under Section 1221 of the Internal Revenue Code of 1986, as amended. The discussion does not address specific tax consequences that may be relevant to particular persons including, for example, financial institutions, broker-dealers, insurance companies, tax-exempt organizations, and persons in special situations, such as those who hold notes as part of a straddle, hedge, conversion transaction, or other integrated investment. In addition, this discussion does not address U.S. federal alternative minimum tax consequences or any aspect of state, local or foreign taxation. This discussion is based upon current U.S. federal income tax laws, regulations, rulings and judicial decisions, all of which are subject to change, possibly with retroactive effect. In our counsel’s opinion, the notes qualify as indebtedness and as securities for federal income tax purposes, and the following discussion assumes that this treatment is correct.

      For purposes of this discussion, you are a “U.S. Holder” if you are a beneficial owner of a note and are a U.S. citizen or resident, a corporation, partnership or other entity created or organized in or under the laws of the U.S. or of any political subdivision thereof, an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or a trust if a U.S. court is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions. You are a “Non-U.S. Holder” if you are a holder of a note who is not a U.S. Holder.

      Prospective purchasers of the notes are urged to consult their own tax advisors concerning the specific U.S. federal income and estate tax consequences to them of owning and disposing of the notes, as well as the application of state, local and foreign income and other tax laws.

Tax Consequences to U.S. Holders

	Taxation of Interest

      If you are a U.S. Holder, interest on your notes generally will be taxable as ordinary interest income at the time payments are accrued or are received in accordance with your regular method of accounting for federal income tax purposes. The notes are not expected to be issued to investors with “original issue discount” for U.S. federal income tax purposes.

	Sale, Exchange or Retirement of the Notes

      Upon the sale, exchange or retirement of the notes, you will recognize gain or loss equal to the difference, if any, between the amount realized upon the sale, exchange or retirement (less any portion allocable to accrued and unpaid interest) and your adjusted tax basis in the notes. Your adjusted tax basis in the notes generally will be your cost for the notes, less any principal payments you receive.

      The gain or loss you recognize on the sale, exchange or retirement of the notes will be capital gain or loss. The gain or loss will be long-term capital gain or loss if you have held the notes for more than twelve months. Long-term capital gain is subject to a maximum federal tax rate of 15% for U.S. Holders other than corporations. The deductibility of capital losses by U.S. Holders is subject to limitation.

      To the extent that the amount realized represents accrued but unpaid interest, that amount must be taken into account as interest income, if it was not previously included in your income. Please read “— Taxation of Interest” above.

	Exchange Offer

      The exchange offer described above under “Exchange Offer; Registration Rights” through which U.S. Holders will be entitled to exchange their notes for exchange notes, should not produce, for federal income tax purposes, recognizable gain or loss to either us or a U.S. Holder of an exchange note because

73

---

Table of Contents

      If we fail to register the notes or if the exchange offer is not consummated within the required period of time (and under certain other circumstances), then special interest may accrue and become payable with respect to the notes. Our payment of special interest on your notes should not result in a deemed taxable exchange of the notes.

Tax Consequences to Non-U.S. Holders

	Taxation of Interest

      If you are a Non-U.S. Holder, you generally will not be subject to U.S. federal income or withholding tax on interest paid on the notes so long as that interest is not effectively connected with your conduct of a trade or business within the U.S., and you:

	•	do not actually or constructively own 10% or more of the total combined voting power of all of our stock;
	•	are not a “controlled foreign corporation” with respect to which we are a “related person” within the meaning of the Code; and
	•	are not a bank receiving the interest pursuant to a loan agreement in the ordinary course of your trade or business.

      In addition, for the exemption from U.S. federal income and withholding taxes to apply a Non-U.S. Holder must provide us with a properly completed and executed Form W-8 BEN, or other applicable form, as provided for in the Treasury Regulations certifying that the beneficial owner of the note is a foreign person. If these conditions are not satisfied, then interest paid on the notes will be subject to U.S. federal income and withholding tax at a rate of 30% unless that rate is reduced or eliminated pursuant to an applicable tax treaty.

	Sale, Exchange or Retirement of the Notes

      Generally, any capital gain you recognize on the sale, exchange, retirement or other taxable disposition of a note will be exempt from U.S. federal income and withholding tax, provided that:

	•	the gain is not effectively connected with your conduct of a trade or business within the U.S.; and
	•	if you are an individual, you are not present in the U.S. for 183 days or more during the taxable year.

	Effectively Connected Income

      If interest, gain or other income you recognize on a note is effectively connected with your conduct of a trade or business within the U.S., you will be exempt from the withholding tax previously discussed if you provide us with a properly completed and executed Form W-8 ECI, but generally will be subject to U.S. federal income tax on the interest, gain or other income at regular federal income tax rates. In addition to regular U.S. federal income tax, if you are a corporation, you may be subject to a branch profits tax equal to 30% of your effectively connected earnings and profits, as adjusted for certain items, unless you qualify for a lower rate under an applicable tax treaty.

	Federal Estate Taxes

      A note held by an individual who at the time of death is not a citizen or resident of the U.S. will not be subject to U.S. federal estate tax as a result of such individual’s death, provided that the individual does not actually or constructively own 10% or more of the combined voting power of all our stock and

Information Reporting and Backup Withholding

      We will, where required, report to you and the Internal Revenue Service the amount of any interest paid on the notes in each calendar year and the amounts of tax withheld, if any, with respect to those payments. A noncorporate U.S. Holder may be subject to information reporting and to backup withholding at the rate of specified in the Internal Revenue Code with respect to payments of interest made on a note, or proceeds of the disposition of a note before maturity, unless the U.S. Holder provides a correct taxpayer identification number or proof of an applicable exemption and otherwise complies with applicable requirements of the information reporting and backup withholding rules.

      In the case of payments of interest to Non-U.S. Holders, backup withholding tax and certain information reporting requirements will not apply to payments with respect to which either the requisite certification, as described above, has been received or an exemption has otherwise been established, provided that neither we nor our payment agent has actual knowledge that the holder is a U.S. person or that the conditions of any other exemption are not in fact satisfied.

      Generally, information reporting and backup withholding requirements will apply, however, to the gross proceeds paid to a Non-U.S. Holder on the disposition of the notes by or though a U.S. office of a U.S. or foreign broker, unless the Non-U.S. Holder provides the certification described above or otherwise establishes an exemption. Information reporting requirements, but not backup withholding, will also apply to payment of the proceeds of a disposition of the notes by or through a foreign office of a U.S. broker or foreign brokers with certain types of relationships to the U.S. unless the broker has documentary evidence in its file that the holder of the notes is not a U.S. person and the broker has no actual knowledge to the contrary, or the holder establishes an exemption. Neither information reporting nor backup withholding generally will apply to payment of the proceeds of a disposition of the notes by or through a foreign office of a foreign broker not subject to the preceding sentence.

      Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or credited against the holder’s U.S. federal income tax liability, provided that the required information is furnished to the Internal Revenue Service.

PLAN OF DISTRIBUTION

      Each broker-dealer that receives exchange notes for its own account in the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the exchange notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received in exchange for existing notes where the existing notes were acquired as a result of market-making activities or other trading activities.

      We will not receive any proceeds from any sale of exchange notes by broker-dealers. Exchange notes received by broker-dealers for their own account in the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the exchange notes or a combination of these methods of resale, at market prices prevailing at the time of resale, at prices related to those prevailing market prices or at negotiated prices. Any resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any broker-dealer or the purchasers of any exchange notes. Any broker-dealer that resells exchange notes that were received by it for its own account in the exchange offer and any broker or dealer that participates in a distribution of the exchange notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any resale of exchange notes and any commission or concessions received by such person may be considered underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will

Table of Contents

      For a period of 90 days after the consummation of the exchange offer, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer, other than commissions or concessions of any brokers or dealers and will indemnify the holders of the existing notes, including any broker-dealers, against certain liabilities, including liabilities under the Securities Act.

LEGAL MATTERS

      Certain legal matters in connection with the issuance of the exchange notes will be passed upon for us by our attorneys, Haynes and Boone, LLP.

INDEPENDENT AUDITORS

      The audited consolidated financial statements as of December 31, 2003 and 2002, and for the years ended December 31, 2003 and 2002, incorporated by reference in this prospectus and the registration statement have been audited by Ernst & Young LLP, independent public accountants, as indicated in their report with respect thereto, and are incorporated by reference in reliance upon the authority of said firm as experts in accounting and auditing in giving said reports.

      The financial statements for the year ended December 31, 2001 incorporated by reference into this prospectus and the registration statement were audited by Arthur Andersen LLP as indicated in their report with respect thereto which is a copy of a previously issued Arthur Andersen LLP report and said report has not been reissued by Arthur Andersen LLP nor has Arthur Andersen LLP provided a consent to the inclusion of its report on this prospectus. Since we have not been able to obtain the written consent of Arthur Andersen LLP, you will not be able to recover against Arthur Andersen LLP under Section 11 of the Securities Act for any untrue statements of material fact contained in the financial statements audited by Arthur Andersen LLP incorporated by reference herein or any omissions to state a material fact required to be stated herein.

GLOSSARY OF OIL AND GAS TERMS

Terms Used to Describe Quantities of Oil and Natural Gas

Bbl — One stock tank barrel, or 42 US gallons liquid volume, of crude oil or other liquid hydrocarbons.

Bcf — One billion cubic feet of natural gas.

Bcfe — One billion cubic feet of natural gas equivalent, computed on an appropriate energy equivalent basis that one Bbl equal six Mcf.

BOE — One barrel of oil equivalent, converting gas to oil at the ratio of 6 Mcf of gas to 1 Bbl of oil.

MBbl — One thousand Bbls.

Mcf — One thousand cubic feet of natural gas.

Mcfe — One thousand cubic feet of natural gas equivalent, computed on an approximate energy equivalent basis that one Bbl equals six Mcf.

MMcf — One million cubic feet of natural gas.

MMcfe — One million cubic feet of natural gas equivalent, computed on an approximate energy equivalent basis that one Bbl equals six Mcf.

Terms Used to Describe Our Interests in Wells and Acreage

Gross oil and gas wells or acres — Our gross wells or gross acres represents the total number of wells or acres in which we own a working interest.

Net oil and gas wells or acres — Determined by multiplying “gross” oil and natural gas wells or acres by the working interest that we own in such wells or acres represented by the underlying properties.

Terms Used to Assign a Present Value to Our Reserves

Standardized measure of proved reserves — The present value, discounted at 10%, of the after tax net cash flows attributable to estimated net proved reserves. We calculate this amount by assuming that we will sell the oil and gas production attributable to the proved reserves estimated in our independent engineer’s reserve report for the prices we received for the production on the date of the report, unless we had a contract to sell the production for a different price. We also assume that the cost to produce the reserves will remain constant at the costs prevailing on the date of the report. The assumed costs are subtracted from the assumed revenues resulting in a stream of future net cash flows. Estimated future income taxes using rates in effect on the date of the report are deducted from the net cash flow stream. The after-tax cash flows are discounted at 10% to result in the standardized measure of our proved reserves. The standardized measure of our proved reserves is disclosed in our audited financial statements at note 12.

Pre-tax discounted present value — The discounted present value of proved reserves is identical to the standardized measure, except that estimated future income taxes are not deducted in calculating future net cash flows. We disclose the discounted present value without deducting estimated income taxes to provide what we believe is a better basis for comparison of our reserves to other producers who may have different tax rates.

Terms Used to Classify Our Reserve Quantities

Proved reserves — The estimated quantities of crude oil, natural gas and natural gas liquids which, upon analysis of geological and engineering data, appear with reasonable certainty to be recoverable in the future from known oil and natural gas reservoirs under existing economic and operating conditions.

77

---

Table of Contents

      The Securities and Exchange Commission definition of proved oil and gas reserves, per Article 4-10(a)(2) of Regulation S-X, is as follows:

      Proved oil and gas reserves. Proved oil and gas reserves are the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions.

      (a) Reservoirs are considered proved if economic productibility is supported by either actual production or conclusive formation test. The area of a reservoir considered proved includes (A) that portion delineated by drilling and defined by gas-oil and/or oil-water contacts, if any; and (B) the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data. In the absence of information on fluid contacts, the lowest known structural occurrence of hydrocarbons controls the lower proved limit of the reservoir.

      (b) Reserves which can be produced economically through application of improved recovery, techniques (such as fluid injection) are included in the “proved” classification when successful testing by a pilot project, or the operation of an installed program in the reservoir, provides support for the engineering analysis on which the project or program was based.

      (c) Estimates of proved reserves do not include the following: (1) oil that may become available from known reservoirs but is classified separately as “indicated additional reserves”; (2) crude oil, natural gas, and natural gas liquids, the recovery of which is subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics, or economic factors; (3) crude oil, natural gas, and natural gas liquids, that may occur in undrilled prospects; and (4) crude oil, natural gas, and natural gas liquids, that may be recovered from oil shales, coal, gilsonite and other such sources.

Proved developed reserves — Proved reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

Proved undeveloped reserves — Proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required.

Terms Which Describe the Cost to Acquire Our Reserves

Reserve replacement costs — Our reserve replacement costs compare the amount we spent to explore for oil and gas and to drill and complete wells during a period, with the increases in reserves during the period. This amount is calculated by dividing the net change in our evaluated oil and property costs during a period by the change in proved reserves plus production over the same period.

Terms Which Describe the Productive Life of a Property or Group of Properties

Reserve life — A measure of the productive life of an oil and gas property or a group of oil and gas properties, expressed in years. Reserve life equals the estimated net proved reserves attributable to a property or group of properties divided by production from the property or group of properties for the four fiscal quarters preceding the date as of which the proved reserves were estimated.

Terms Used to Describe the Legal Ownership of Our Oil and Gas Properties

Royalty interest — A real property interest entitling the owner to receive a specified portion of the gross proceeds of the sale of oil and natural gas production or, if the conveyance creating the interest provides, a specific portion of oil and natural gas produced, without any deduction for the costs to explore for, develop or produce the oil and natural gas. A royalty interest owner has no right to consent to or approve the

78

---

Table of Contents

Working interest — A real property interest entitling the owner to receive a specified percentage of the proceeds of the sale of oil and natural gas production or a percentage of the production, but requiring the owner of the working interest to bear the cost to explore for, develop and produce such oil and natural gas. A working interest owner who owns a portion of the working interest may participate either as operator or by voting his percentage interest to approve or disapprove the appointment of an operator and drilling and other major activities in connection with the development and operation of a property.

Terms Used to Describe Seismic Operations

Seismic data — Oil and gas companies use seismic data as their principal source of information to locate oil and gas deposits, both to aid in exploration for new deposits and to manage or enhance production from known reservoirs. To gather seismic data, an energy source is used to send sound waves into the subsurface strata. These waves are reflected back to the surface by underground formations, where they are detected by geophones which digitize and record the reflected waves. Computers are then used to process the raw data to develop an image of underground formations.

2-D seismic data — 2-D seismic survey data has been the standard acquisition technique used to image geologic formations over a broad area. 2-D seismic data is collected by a single line of energy sources which reflect seismic waves to a single line of geophones. When processed, 2-D seismic data produces an image of a single vertical plane of sub-surface data.

3-D seismic — 3-D seismic data is collected using a grid of energy sources, which are generally spread over several miles. A 3-D survey produces a three dimensional image of the subsurface geology by collecting seismic data along parallel lines and creating a cube of information that can be divided into various planes, thus improving visualization. Consequently, 3-D seismic data is a more reliable indicator of potential oil and natural gas reservoirs in the area evaluated.

AVO (Amplitude versus Offset) — AVO is a risk reducing technique which has been developed over many years and has gained increasing acceptance over the last several years. It involves evaluating the variation of seismic reflection energy over a range of source to receiver offsets to better understand the lithology and pore fluid content of a target horizon. This technique, when used in conjunction with 3-D seismic interpretation can result in significant risk reduction for exploratory and development wells.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.	Indemnification of Directors and Officers.

      Section 145 of the General Corporation Law of the State of Delaware, pursuant to which we are incorporated, provides generally and in pertinent part that a Delaware corporation may indemnify its directors, officers, employees and agents (or persons serving at our request as a director, officer, employee or agent of another entity) against expenses, judgments, fines, and settlements actually and reasonably incurred by them in connection with any civil, criminal, administrative, or investigative suit or action except actions by or in the right of the corporation if, in connection with the matters in issue, they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and in connection with any criminal suit or proceeding, if in connection with the matters in issue, they had no reasonable cause to believe their conduct was unlawful. Section 145 further provides that in connection with the defense or settlement of any action by or in the right of the corporation, a Delaware corporation may indemnify its directors, officers, employees and agents (or persons serving at our request as a director, officer, employee or agent of another entity) against expenses actually and reasonably incurred by them if, in connection with the matters in issue, they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue, or matter as to which such person has been adjudged liable to the corporation unless the Delaware Court of Chancery or other court in which such action or suit is brought approves such indemnification. Section 145 further permits a Delaware corporation to grant its directors and officers additional rights of indemnification through bylaw provisions and otherwise, and to purchase indemnity insurance on behalf of its directors and officers. Article Eight of our Certificate of Incorporation, as amended, provides that we may, and Article IX of our Bylaws, as amended, provides that we shall, indemnify our directors, officers, employees and agents (or persons serving at our request as a director, officer, employee or agent of another entity) to the full extent of Delaware law.

Item 22.	Undertakings.

      (a) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

      Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission 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 registrant of expenses incurred or paid by a director, officer or controlling person of the registrant 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 registrant 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) The undersigned registrant hereby undertakes to respond to request for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of this Registration Statement through the date of responding to the request.

      (c) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.
