CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain matters discussed or incorporated by reference in this prospectus are “forward-looking statements” intended to qualify for the safe harbors from liability established by the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 (the “Securities Act”) and Section 21E of the Exchange Act. The words “believe,” “expect,” “anticipate,” “plan,” “intend,” “foresee,” “should,” “would,” “could” or other similar expressions are intended to identify forward-looking statements, which are generally not historical in nature. These forward-looking statements are based on our current expectations and beliefs concerning future developments and their potential effect on us. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting us will be those that we anticipate. All comments concerning our expectations for future revenues and operating results are based on our forecasts for our existing operations and do not include the potential impact of any future acquisitions. In particular, this report contains forward-looking statement pertaining to the following:

• our future financial position;

• our business strategy;

• recent and pending acquisitions;

• budgets;

• projected costs, savings and plans;

• objectives of management for future operations;

• legal strategies; and

• legal proceedings.

We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks, contingencies and uncertainties, which may not be exhaustive, relate to, among other matters, the following:

• discovery, estimation, development and replacement of oil and gas reserves;

• decreases in proved reserves due to technical or economic factors;

• drilling of wells and other planned exploitation activities;

• timing and amount of future production of oil and gas;

• the volatility of oil and gas prices;

• availability and terms of capital;

• operating costs such as lease operating expenses, administrative costs and other expenses;

• our future operating or financial results;

• amount, nature and timing of capital expenditures, including future development costs;

• cash flow and anticipated liquidity;

• availability of drilling and production equipment;

• uncertainties related to drilling and production operations in a new region;

• cost and access to natural gas gathering, treatment and pipeline facilities;

• outcome of legal disputes;

iii

• environmental hazards, such as natural gas leaks, oil spills and discharges of toxic gases;

• business strategy and the availability of acquisition opportunities; and

• factors not known to us at this time.

Any of these factors, or a combination of these factors, could materially affect our future financial condition or results of operations and the ultimate accuracy of the forward-looking statements. The forward-looking statements are not guarantees of our future performance, and our actual results and future developments may differ materially from those projected in the forward-looking statements. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including those mentioned in “Risk Factors” beginning on page 11 of this offering circular and in our Annual Report on Form 10-K for the year ended December 31, 2011 and our Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2012, June 30, 2012, and September 30, 2012. These forward-looking statements speak only as of the date of this offering circular, or, if earlier, as of the date they were made. Except as required by law, we undertake no obligation to update publicly or release any revisions to these forward-looking statements to reflect events or circumstances after the date of this report. These cautionary statements qualify all forward-looking statements attributable to us or persons acting on our behalf.

Exchange Offers We are offering to exchange new notes for old notes of the relevant tranche. Each exchange offer is independent of the other, and we may elect to extend one without extending the other

Expiration Date The exchange offers will expire at 11:59 p.m., New York City time, on            ,            , unless we decide to extend them.

Condition to the Exchange Offer The registration rights agreements do not require us to accept old notes for exchange if the applicable exchange offer, or the making of any exchange by a holder of the old notes, would violate any applicable law or interpretation of the staff of the Securities and Exchange Commission. The exchange offers are not conditioned on a minimum aggregate principal amount of old notes being tendered.

These procedures for using DTC’s Automated Tender Offer Program (“ATOP”) require that (i) the exchange agent receive, prior to the expiration date of the applicable exchange offer, a computer generated message known as an “agent’s message” that is transmitted through DTC’s automated tender offer program, and (ii) DTC confirms that:

• DTC has received your instructions to exchange your notes; and

The obligations under the second priority notes and related guarantees, as applicable, are secured by second priority liens on the same collateral.

Subsidiary Guarantees The payment of the principal, premium, if any, and interest on the notes is jointly and severally guaranteed by certain of our existing domestic and certain of our future subsidiaries, whom we refer to as the “subsidiary guarantors.”

Ranking The notes of each tranche are our senior obligations.

The new first priority notes, like the old first priority notes:

• will rank equally in right of payment with all of our existing and future senior indebtedness;

• will rank effectively junior in right of payment to all of our other existing and future indebtedness secured by property other than the collateral to the extent of the value of the property securing such indebtedness;

• will rank senior in right of payment to all of our future subordinated indebtedness;

• will rank effectively senior to the second priority notes and our unsecured indebtedness to the extent of the value of the collateral;

• will be fully and unconditionally guaranteed, jointly and severally, by EOC on a senior first-priority secured basis (to the extent of the value of the collateral owned by EOC) and, subject to “Description of the Notes—Security—General,” on a senior unsecured basis by the other subsidiary guarantors; and

• will be structurally junior to all existing and future indebtedness and other liabilities, including trade payables, of our non-guarantor subsidiaries (other than indebtedness and other liabilities owed to us, if any).

The new second priority notes, like the old second priority notes:

• will rank equally in right of payment with all of our existing and future senior indebtedness;

• will rank effectively junior in right of payment to all of our existing and future indebtedness secured by property other than the collateral, to the extent of the value of the property securing such indebtedness;

• will rank senior in right of payment to all of our future subordinated indebtedness;

• will rank effectively junior to the first priority notes to the extent of the value of the collateral;

• will be fully and unconditionally guaranteed, jointly and severally, by EOC on a senior second-priority secured basis (to the extent of the value of the collateral owned by EOC) and, subject to “Description of the Notes—Security—General,” on a senior unsecured basis by the other subsidiary guarantors; and

• will be structurally junior to all existing and future indebtedness and other liabilities, including trade payables, of our non-guarantor subsidiaries (other than indebtedness and other liabilities owed to us, if any).

6

Subsidiary Guarantees Each guarantee of the new first priority notes by a subsidiary guarantor, like each guarantee of the old first priority notes by such subsidiary guarantor:

• will be a general senior obligation of the subsidiary guarantor; provided that the guarantee from EOC will be secured by a first priority security interest in the collateral owned by EOC;

• in the case of the guarantee from each subsidiary guarantor other than EOC, will not initially be secured;

• will rank equally in right of payment with all of the existing and future senior indebtedness of the subsidiary guarantor, including its guarantees of our other senior indebtedness;

• in the case of the guarantee from EOC, will rank effectively senior to all unsecured indebtedness of EOC and the guarantee from EOC of the second priority notes, in each case to the extent of the value of the collateral owned by EOC;

• will rank effectively junior in right of payment to all existing and future indebtedness of the subsidiary guarantor that is secured by assets other than the collateral, to the extent of the value of the assets securing such indebtedness;

• will rank senior in right of payment to any future subordinated indebtedness of the subsidiary guarantor; and

• will be structurally junior to all existing and future indebtedness and other liabilities, including trade payables, of any subsidiary of the subsidiary guarantor that does not guarantee the first priority notes (other than indebtedness and other liabilities owed to us, if any)

Each guarantee of the new second priority notes by a subsidiary guarantor, like each guarantee of the old second priority notes by such subsidiary guarantor:

• will be a general senior obligation of the subsidiary guarantor; provided that the guarantee from EOC will be secured by a second priority security interest in the collateral owned by EOC;

• in the case of the guarantee from each subsidiary guarantor other than EOC, will not initially be secured;

• will rank equally in right of payment with all of the existing and future senior indebtedness of the subsidiary guarantor, including its guarantees of our other senior indebtedness;

• in the case of the guarantee from EOC, will rank effectively senior to all unsecured indebtedness of EOC, and effectively junior to the guarantee from EOC of the first priority notes, in each case to the extent of the value of the collateral owned by EOC;

7

• will rank effectively junior in right of payment to all existing and future indebtedness of the subsidiary guarantor that is secured by assets other than the collateral, to the extent of the value of the assets securing such indebtedness;

• will rank senior in right of payment to any future subordinated indebtedness of the subsidiary guarantor; and

• will be structurally junior to all existing and future indebtedness and other liabilities, including trade payables, of any subsidiary of the subsidiary guarantor that does not guarantee the second priority notes (other than indebtedness and other liabilities owed to us, if any).

Intercreditor Agreement The liens securing the second priority notes (and any additional second priority notes that we may issue in the future) are subordinated to those securing our obligations respecting the first priority notes (and any additional first priority notes that we may issue in the future) in accordance with the terms of the intercreditor agreement. Pursuant to the terms of the intercreditor agreement, the holders of the second priority notes have subordinated their payment rights in respect of the collateral to those of the holders of the first priority notes (and the holders of any additional first priority notes that we may issue in the future). The indentures governing the notes permit us, subject to certain limitations, to incur additional first priority notes that will be secured equally with the outstanding first priority notes, and to incur additional second priority notes that will be secured equally with the outstanding second priority notes. The amounts of any such additional future first priority notes and second priority notes may be significant. Please read “Risk Factors—Risks Related to an Investment in the Notes—The collateral securing EOC’s guarantee of the notes and, if we or any other subsidiary guarantors become pledgors in the future, our obligations under the notes and the obligations of the other subsidiary guarantors under their guarantees of the notes, may be diluted if we, EOC or the other subsidiary guarantors issue debt that is secured equally and ratably by the same collateral, if the collateral is sold or if the intercompany loan constituting collateral is repaid.” The terms of the intercreditor agreement are set forth under “Description of the Notes—Intercreditor Agreement.”

Optional Redemption Beginning on March 1, 2015, we may redeem some or all of the first priority notes and, subject to certain limitations, the second priority notes, at the redemption prices listed under “Description of the Notes—Optional Redemption,” together with any accrued and unpaid interest on the notes to the date of redemption. Prior to March 1, 2015, we may redeem some or all of the first priority notes and, subject to certain limitations, the second priority notes, at a “makewhole” redemption price described under “Description of the Notes—Optional Redemption,” together with any accrued and unpaid interest to the date of redemption.

8

In addition, at any time prior to March 1, 2015, we may redeem up to 35% of the first priority notes and, subject to certain limitations, 35% of the second priority notes, from the proceeds of certain sales of our equity securities at 112.00% of the principal amount, plus accrued and unpaid interest, if any, to the date of redemption, if at least 65% of the aggregate principal amount of the notes issued under the relevant indenture remains outstanding after such redemption and the redemption occurs within 180 days after the date of the closing of such equity offering. Please read “Description of the Notes—Optional Redemption.”

Change of Control Upon the occurrence of a change of control (as described under “Description of the Notes—Repurchase at the Option of Holders—Change of Control”), we must offer to repurchase the notes at 101% of the principal amount of the notes, plus accrued and unpaid interest to the date of repurchase.

Certain Covenants We will issue each tranche of new notes under a separate indenture, which will be the same indenture for the relevant tranche of old notes. The indenture governing each tranche of notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

• pay distributions on, repurchase or redeem our capital stock or repurchase or redeem our subordinated debt or, in the case of the indenture governing the first priority notes, the second priority notes;

• make investments;

• incur or guarantee additional indebtedness or issue preferred stock;

• create or incur certain liens;

• sell assets;

• consolidate, merge or transfer all or substantially all of our assets;

• enter into agreements that restrict distributions or other payments from our restricted subsidiaries to us;

• engage in transactions with affiliates; and

• create unrestricted subsidiaries.

These covenants are subject to important exceptions and qualifications that are described under “Description of Notes.”

If there is no continuing default under an indenture and the tranche of notes issued thereunder achieves an investment grade rating from both Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services, many of these covenants will be suspended with respect to that tranche.

9

No Transfer Restriction; Trading Market for the New Notes The new notes generally will be freely transferable and after the exchange offers will trade together with the original notes of the relevant tranche. There can be no assurance as to the liquidity of any market for the notes.

We do not intend to apply for a listing of the new notes on any securities exchange or any automated dealer quotation system.

Original Issue Discount The notes of each tranche were issued with original issue discount for U.S. federal income tax purposes. As a result, in addition to the stated interest on the notes of each tranche, a U.S. holder (as defined in “Certain United States Federal Tax Consequences”) will be required to include such original issue discount in gross income as ordinary income as it accrues, in advance of the receipt of cash attributable to such income and regardless of such U.S. holder’s regular method of accounting for U.S. federal income tax purposes. Please read “Certain United States Federal Tax Consequences—Consequences to U.S. Holders—Original Issue Discount.”

Risk Factors Investing in the new notes involves risks. Please read “Risk Factors” beginning on page 11 for a discussion of certain factors you should consider in evaluating an investment in the new notes.

10

RISK FACTORS

An investment in our notes involves risks. You should carefully consider all of the information contained in this prospectus and the documents incorporated by reference as provided under “Where You Can Find More Information,” including our Annual Report on Form 10-K for the year ended December 31, 2011 and our Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2012, June 30, 2012, and September 30, 2012. This prospectus and the documents incorporated by reference also contain forward-looking statements that involve risks and uncertainties. Please read “Forward-Looking Statements.” Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including the risks described below, elsewhere in this prospectus and in the documents incorporated by reference. If any of these risks occur, our business, financial condition or results of operation could be adversely affected.

Risks Related to an Investment in the New Notes

We may not be able to generate enough cash flow to meet our debt obligations.

We expect our earnings and cash flow to vary significantly from year to year due to the cyclical nature of our industry. As a result, the amount of debt that we can service in some periods may not be appropriate for us in other periods. Additionally, our future cash flow may be insufficient to meet our debt obligations and commitments, including the notes. Any insufficiency could negatively impact our business. A range of economic, competitive, business and industry factors will affect our future financial performance, and, as a result, our ability to generate cash flow from operations and to pay our debt, including the notes. Many of these factors, such as oil and natural gas prices, economic and financial conditions in our industry and the global economy or competitive initiatives of our competitors, are beyond our control.

If we do not generate enough cash flow from operations to satisfy our debt obligations, we may have to undertake alternative financing plans, such as:

• refinancing or restructuring our debt;

• selling assets;

• reducing or delaying capital investments; or

• seeking to raise additional capital.

However, we cannot assure you that undertaking alternative financing plans, if necessary, would allow us to meet our debt obligations. Our inability to generate sufficient cash flow to satisfy our debt obligations, including our obligations under the notes, or to obtain alternative financing, could materially and adversely affect our ability to make payments on the notes and our business, financial condition, results of operations and prospects.

We may not be able to repurchase the notes.

Under the terms of the indenture governing each tranche of the notes, you may require us to repurchase all or a portion of the notes if the proceeds from certain dispositions are not applied in a specific manner or in the event of a change in control as defined in the indenture governing the notes. The revolving credit facility, the 11.5% Convertible Bonds and the 5.5% Convertible Notes each contain a similar obligation to repurchase following a change of control. We may not have enough funds to pay the repurchase price on a purchase date. Other debt agreements to which we become a party may provide that our obligation to purchase the notes would be an event of default under such agreement. As a result, we may be restricted or prohibited from repurchasing the notes. If we are prohibited from repurchasing the notes, we could seek the consent of our then-existing lenders to repurchase the notes, or we could attempt to refinance the borrowings that contain such prohibition. There can be no assurance that we would be able to refinance our indebtedness or, if a refinancing were to occur,

11

that the refinancing would be on terms favorable to us. If we are unable to obtain a consent or refinance the debt, we could not repurchase the new notes. Our failure to repurchase tendered notes of either tranche would constitute a default under the indenture governing the notes of that tranche and would likely also constitute a default under the terms of other indebtedness that we incur.

The term “change in control” is limited to certain specified transactions and may not include other events that might adversely affect our financial condition. Our obligation to repurchase the notes upon a change in control would not necessarily afford holders of notes protection in the event of a highly leveraged transaction, reorganization, merger or similar transaction involving us.

The change of control put right might not be enforceable.

The Chancery Court of Delaware has raised the possibility in a published decision that a change of control put right occurring as a result of a failure to have “continuing directors” comprising a majority of a board of directors, which is similar to a right provided in the indenture governing the notes, might be unenforceable on public policy grounds. Although we are a Nevada corporation, a court applying Nevada law might treat this decision as persuasive.

Despite our and our subsidiaries’ current level of indebtedness, we may be able to incur substantially more indebtedness.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of the indenture governing each tranche of the notes does not completely prohibit us or our subsidiaries from doing so. Accordingly, we or our subsidiaries could incur significant additional indebtedness in the future, some of which may be incurred by non-guarantor subsidiaries and some of which could constitute secured indebtedness with respect to assets that do not secure the notes, and which would have priority in any proceeds distributed in connection with any bankruptcy, liquidation, reorganization or similar proceeding to the extent derived from the collateral securing such debt. If we incur any additional indebtedness that ranks equally with the notes and the guarantees, the holders of that indebtedness will be entitled to share ratably with the holders of the notes and the related guarantees in any proceeds from sales of assets not pledged as security for the notes that is distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of us. This may have the effect of reducing the amount of proceeds paid to you. If new indebtedness is added to our current debt levels, the related risks that we and our subsidiaries now face could intensify.

Your right to receive payments on the notes is effectively subordinated to the right of lenders who may have a security interest in our assets to the extent of the value of those assets.

Our obligations under the notes and the guarantors’ obligations under their guarantees of the notes are secured by only a portion of our assets, and our future secured debt, if any, may be secured by our other assets, which could include substantially all of our oil and natural gas properties and the ownership interests of substantially all of our subsidiaries. If we are declared bankrupt or insolvent, or if we default under such indebtedness, the funds borrowed thereunder, together with accrued interest, could become immediately due and payable. If we were unable to repay such indebtedness, the lenders under such indebtedness could foreclose on the assets pledged as security for such indebtedness to the exclusion of holders of the notes, even if an event of default exists under the indenture governing the notes at such time. Furthermore, if the lenders foreclose and sell the pledged equity interests in any guarantor in a transaction permitted under the terms of the indenture governing the notes, then such guarantor will be released from its guarantee of the notes automatically and immediately upon such sale. In any such event, because the notes are not secured by all of such assets or by the equity interests in all of our subsidiaries, it is possible that there would be no assets from which your claims could be satisfied other than those securing the notes and the guarantees, or that existing assets might be insufficient to satisfy your claims in full.

12

Claims of noteholders will be structurally subordinated to claims of creditors of any of our subsidiaries that do not guarantee the notes.

None of our existing foreign subsidiaries guarantee the notes. Subject to certain limitations, the indentures governing the notes permit us to form or acquire certain subsidiaries that are also not guarantors of the notes and permits our non-guarantor subsidiaries to acquire assets and incur indebtedness. Noteholders will not have any claim as creditors against any of our non-guarantor subsidiaries to the assets and earnings of those subsidiaries. The claims of the creditors of those subsidiaries, including their trade creditors, banks and other lenders, to assets not securing the notes and the guarantees would have priority over any of our claims or those of our other subsidiaries as equity holders of the non-guarantor subsidiaries. Consequently, in any insolvency, liquidation, reorganization, dissolution or other winding-up of any of the non-guarantor subsidiaries, creditors of those subsidiaries would be paid before any amounts would be distributed to us or to any of the guarantors as equity, and thus may not be available to satisfy our obligations under the notes and other claims against us or the guarantors.

Our ability to repay our debt, including the notes, is affected by the cash flow generated by our subsidiaries.

Our subsidiaries own all of our oil and gas properties and conduct all of our operations. Accordingly, repayment of our indebtedness, including the notes, is dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. None of our existing foreign subsidiaries guarantee our obligations under the notes. Unless they guarantee the notes, any of our future subsidiaries will not have any obligation to pay amounts due on the notes or to make funds available for that purpose. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness, including the notes. Each subsidiary is a distinct legal entity and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. While the indenture governing the notes limits the ability of our restricted subsidiaries to incur consensual encumbrances or restrictions on their ability to pay dividends or make other intercompany payments to us, these limitations are subject to waiver and certain qualifications and exceptions. In the event that we do not receive sufficient distributions from our subsidiaries, we may be unable to make required principal, premium, if any, and interest payments on our indebtedness, including the new notes.

The notes are secured only to the extent of the value of the assets that are granted as security for EOC’s guarantee of the notes, and there may be no additional collateral for the notes in the future. In addition, a portion of the collateral is an intercompany loan that is subordinated to existing and future secured debt; therefore, the value of such note may be reduced to the extent that we or our subsidiaries incur secured debt.

The collateral securing the notes and the guarantees is currently limited to 65% of the capital stock of Endeavour International Holding B.V. (which is owned by EOC) and a subordinated revolving intercompany loan payable by Endeavour Energy UK Limited (“EEUK”) to EOC. No appraisal of the value of the collateral has been made in connection with either the offering of the old notes or the exchange offers, and the fair market value of the collateral is subject to fluctuations based on factors that include, among others, general economic conditions and similar factors. The amount to be received upon a sale of the collateral would be dependent on numerous factors, including, but not limited to, the actual fair market value of the collateral at such time, the timing and the manner of the sale, and the availability of buyers. By its nature, portions of the collateral may be illiquid and may have no readily ascertainable market value. In the event of a foreclosure, liquidation, bankruptcy or similar proceeding, the collateral may not be sold in a timely or orderly manner, and the proceeds from any sale or liquidation of this collateral may not be sufficient to pay our obligations under the notes. In addition, the subordinated revolving intercompany loan comprising a portion of the collateral will be subordinated to existing and future secured indebtedness of EEUK on whatever terms the secured creditors of EEUK may require, and releases of collateral from the liens securing the guarantees are permitted under some circumstances. See “Description of the Notes—Security—Release of Collateral.” To the extent that we or our subsidiaries incur

13

secured debt, the value of such note may be reduced. If the proceeds of any sale of collateral are not sufficient to repay all amounts due on the notes, the holders of the notes (to the extent not repaid from the proceeds of the sale of the collateral) would have only a senior unsecured, unsubordinated claim against our remaining assets.

None of our assets, and only a portion of our subsidiaries’ assets, secure EOC’s guarantee. The guarantees made by our other domestic subsidiaries are not secured. See “Description of the Notes—Security.” For example, the collateral does not include, among other things:

• any of our real or personal property;

• any of our subsidiaries’ real or personal property other than certain intercompany indebtedness and 65% of the stock of our first-tier foreign subsidiaries;

• any stock of our domestic subsidiaries or foreign subsidiaries other than first-tier foreign subsidiaries; and

• any deposit accounts and securities accounts.

The collateral securing our obligations under the notes and the guarantees is shared. If there is a default, the value of the collateral may not be sufficient to repay holders of the new notes.

EOC’s guarantee of our obligations under the first priority notes is secured by a first-priority lien on the collateral owned by EOC, and our obligations under the first priority notes and the guarantees by the other subsidiary guarantors of our obligations under the first priority notes may in the future be secured by a first-priority lien on additional collateral owned by us or such other subsidiary guarantors, as described under “Description of the Notes—Security.” Similarly, EOC’s guarantee of our obligations under the second priority notes is secured by a second-priority lien on the collateral owned by EOC, and our obligations under the second priority notes and the guarantees by the other subsidiary guarantors of our obligations under the second priority notes may in the future be secured by a second-priority lien on additional collateral owned by us or such other subsidiary guarantors, as described under “Description of the Notes—Security.” The relative priority of the liens on the collateral is governed by the intercreditor agreement. Accordingly, any proceeds received upon a realization by foreclosure or bankruptcy proceedings of the collateral will first be applied to the costs and expenses incurred with such realization and second equally and ratably to the first priority notes, before any amounts will be available to pay the holders of second priority notes. See “Description of the Notes—Security” and “Description of the Notes—Intercreditor Agreement.” In the case of certain sales of assets constituting collateral outside of foreclosure or bankruptcy proceedings, proceeds generated from such sales that are required under the indentures to be used to reduce indebtedness will be applied first to make an offer to repurchase first priority notes before being offered to repurchase any second priority notes. See “Description of the Notes—Repurchase at the Option of Holders—Asset Sales.”

To the extent that holders of other secured debt or third parties enjoy liens (including statutory liens) on the collateral, whether or not permitted by the indentures, such holders or third parties may have rights and remedies with respect to the collateral securing the notes and the guarantees that, if exercised, could reduce the proceeds available to satisfy the obligations under, the notes and the guarantees. As a result, if there is a default, the value of the collateral may not be sufficient to repay the holders of either the first priority notes or the second priority notes. Even if the collateral is sufficient to repay the first priority notes, it may not be sufficient to repay the second priority notes. Any claim for the difference between our obligations under the respective tranche of notes and the amount realized by holders of such notes from the sale of the collateral will rank equally in right of payment with all of our other unsecured unsubordinated indebtedness, including trade payables.

14

The right of holders of second priority notes to exercise remedies with respect to the collateral is extremely limited, even during an event of default under the indenture governing the second priority notes.

If the first priority notes are outstanding, any actions that may be taken in respect of any of the collateral, including the ability to cause the commencement of enforcement proceedings against the collateral and to control the conduct of such proceedings, will be controlled and directed by holders of the first priority notes. See “Description of the Notes—Intercreditor Agreement.” In those circumstances, subject to limited exceptions, the second priority collateral agent, on behalf of itself, the second priority notes trustee and the holders of the second priority notes, will not have the ability to control or direct such actions, even if an event of default under the indenture governing the second priority notes has occurred or if the rights of the second priority notes trustee, the second priority collateral agent or the holders of the second priority notes are or may be adversely affected. The first priority collateral agent, the first priority notes trustee and the holders of the first priority notes are under no obligation to take into account the interests of the second priority notes trustee, the second priority collateral agent or the holders of the second priority notes when determining whether and how to exercise their rights with respect to the collateral, and their interests and rights may be significantly different from or adverse to those of the holders of the second priority notes. To the extent that collateral is released from the first priority liens, subject to certain conditions, the second priority liens securing the second priority notes and the guarantees related thereto will also automatically be released without any consent or notice to the second priority collateral agent, except that such release will not occur upon the release of collateral in connection with the full repayment of our obligations under the first priority notes. See “Description of the Notes—Intercreditor Agreement.” Subject to certain limitations, we may incur additional first priority notes that will share in the first priority liens on the collateral and to which the second priority liens securing the second priority notes obligations will be junior, and the amounts of such additional first priority notes may be significant. See “Description of the Notes—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.”

The ability of the collateral agents to foreclose on the collateral securing the notes and related guarantees may be limited pursuant to bankruptcy laws.

The right of the collateral agent for each tranche of the notes, as a secured party under the Security Documents for the benefit of itself and the holders of the applicable notes, to foreclose upon and sell the collateral upon the occurrence of a payment default is likely to be significantly impaired by U.S. or foreign bankruptcy laws, including the automatic stay provision contained in Section 362 of the Bankruptcy Code.

Under federal bankruptcy laws, a secured creditor is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from such a debtor, without bankruptcy court approval. Moreover, federal bankruptcy laws generally permit a debtor to continue to retain and use collateral even though that debtor is in default under the debt instruments so long as the secured creditor is afforded “adequate protection” of its interest in the collateral. Although the precise meaning of the term “adequate protection” may vary according to circumstances, it is intended in general to protect a secured creditor against any diminution in the value of the creditor’s interest in its collateral. Accordingly, the bankruptcy court may find that a secured creditor is “adequately protected” if, for example, the debtor makes certain cash payments or grants the creditor liens on additional or replacement collateral as security for any diminution in the value of the collateral occurring for any reason during the pendency of the bankruptcy case.

In view of the lack of a precise definition of the term “adequate protection” and the broad discretionary powers of a bankruptcy court, we cannot predict whether or when the collateral agent could foreclose upon or sell the collateral or whether or to what extent holders of the applicable notes would be compensated for any delay in payment or loss of value of the collateral following the commencement, and during the pendency, of a bankruptcy case. Furthermore, if a bankruptcy court determines that the value of the collateral is not sufficient to repay all amounts due on the applicable tranche of notes, holders of such notes would hold “under-secured claims.” Federal bankruptcy laws do not permit the payment or accrual of interest, costs and attorneys’ fees for

15

“under-secured claims” during a debtor’s bankruptcy case. In addition, the relevant collateral agent’s ability to foreclose on the collateral on behalf of the holders of the applicable notes may be subject to lack of perfection, the consent of third parties, prior liens and practical problems associated with the realization of the collateral agent’s security interest in the collateral.

The collateral securing EOC’s guarantee of the notes and, if we or any other subsidiary guarantors become pledgors in the future, our obligations under the notes and the obligations of the other subsidiary guarantors under their guarantees of the notes, may be diluted if we, EOC or the other subsidiary guarantors issue debt that is secured equally and ratably by the same collateral, if the collateral is sold or if the intercompany loan constituting collateral is repaid.

The collateral that secures EOC’s guarantee of the notes and, if we or any other subsidiary guarantors become pledgors in the future, our obligations under the notes and the obligations of the other subsidiary guarantors under their guarantees of the notes, may secure additional first priority notes or second priority notes and related guarantees that we incur in the future, subject to restrictions on our or the subsidiary guarantors’ ability to incur debt and liens under a potential future credit agreement and the indenture governing such notes. Further, we may incur future indebtedness that will be secured by substantial assets of ours that do not secure obligations respecting the notes. See “Description of the Notes—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.” The indentures do not require that we maintain the current level of collateral or maintain a specific ratio of indebtedness to asset values. Any additional notes issued pursuant to the indentures and any related guarantees by the subsidiary guarantors will rank pari passu with the first priority notes or the second priority notes or the related guarantees, as applicable, and be entitled to the same rights and priority with respect to the collateral as the applicable tranche of notes. Thus, the issuance of additional notes pursuant to either indenture may have the effect of significantly diluting the ability of holders of the applicable tranche of notes to recover payment in full from the then existing pool of collateral. Subject to the limitations provided in the indenture, we and our subsidiaries may sell assets, including the collateral. In addition, the value of the intercompany loan constituting a portion of the collateral may be diminished by the amounts of any repayments of the same.

Rights of holders of the notes in the collateral may be adversely affected by the failure to perfect security interests in certain collateral acquired in the future that secures the notes or the guarantees of the notes.

We may acquire assets or investments in the future that would be required to be pledged as collateral securing the notes or the guarantees of the notes pursuant to the terms of the indenture. There can be no assurance that the trustees or the collateral agents will monitor, or that we will inform the trustees or the collateral agents of, the future acquisition of assets that would be required to be pledged as collateral, and that the necessary action will be taken to properly perfect the security interest in such after-acquired collateral. Neither the trustees nor the collateral agents have an obligation to monitor the acquisition of additional assets that are required to be pledged as collateral or the perfection of any security interest in such collateral. Such failure to perfect the security interest may result in the loss of the security interest in the collateral or the priority of the security interest in favor of the notes against third parties with respect to such collateral.

Any future pledge of collateral in favor of the holders of the notes might be voidable in bankruptcy.

Any future pledge of collateral in favor of the holders of the notes, including pursuant to security documents delivered after the date of the indentures, might be voidable by the pledgor (as debtor-in-possession) or by its trustee in bankruptcy if certain events or circumstances exist or occur, including, under the Bankruptcy Code, if the pledgor is insolvent at the time of the pledge, the pledge permits the holders of the notes to receive a greater recovery than what the holders of the notes would receive in a liquidation under Chapter 7 of the Bankruptcy Code if the pledge had not been given and a bankruptcy proceeding in respect of the pledgor is commenced within 90 days following the pledge, or, in certain circumstances, a longer period.

16

Federal and state statutes allow courts, under specific circumstances, to void guarantees and require noteholders to return payments received from subsidiary guarantors.

Under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee of the notes could be voided, or claims in respect of a guarantee could be subordinated to all other debts of that subsidiary guarantor, if, among other things, the subsidiary guarantor, at the time it incurred the debt evidenced by its guarantee:

• intended to hinder, delay or defraud any present or future creditor or received less than reasonably equivalent value or fair consideration for the incurrence of such guarantee;

• was insolvent or rendered insolvent by reason of such incurrence;

• was engaged in a business or transaction for which the subsidiary guarantor’s remaining assets constituted unreasonably small capital; or

• intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature.

In addition, any payment by that subsidiary guarantor pursuant to its guarantee could be voided and required to be returned to the subsidiary guarantor, or to a fund for the benefit of our creditors or the creditors of the guarantor.

The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, a subsidiary guarantor would be considered insolvent if:

• the sum of its debts, including contingent liabilities, was greater than the fair saleable value of all of its assets;

• the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or

• it could not pay its debts as they become due.

Each subsidiary guarantee contains a provision intended to limit the guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. This provision may not be effective to protect the subsidiary guarantees from being voided under fraudulent transfer law or may eliminate the guarantor’s obligations or reduce the guarantor’s obligations to an amount that effectively makes the guarantee worthless. In a recent Florida bankruptcy case, this kind of provision was found to be ineffective to protect the guarantees.

Many of the covenants contained in each indenture will be suspended if the notes issued thereunder are rated investment grade by both Standard & Poor’s and Moody’s and no default has occurred and is continuing.

Many of the covenants in each indenture governing the notes will be suspended if the notes issued thereunder are rated investment grade by both Standard & Poor’s and Moody’s, provided at such time no default has occurred and is continuing under the indenture. The covenants restrict, among other things, our ability to pay distributions on our capital stock, incur debt and to enter into certain other transactions. However, suspension of these covenants would allow us to engage in certain transactions that would not have been permitted while these covenants were in force, and the effects of any such transactions will be permitted to remain in place even if the notes are subsequently downgraded below investment grade. Please read “Description of the Notes—Certain Covenants—Effectiveness of Covenants.”

17

Changes in our credit ratings may adversely affect the market price of the notes.

Market prices for the notes depend on a number of factors, including our credit ratings with major credit rating agencies. Credit rating agencies continually review their ratings for the companies that they follow, including us. The credit rating agencies also evaluate the industries in which we operate as a whole and may change their credit rating for us based on their overall view of such industries. A negative change in our rating could have an adverse effect on the market price of the notes of either tranche. A security rating is not a recommendation to buy, sell or hold a security and may be subject to withdrawal at any time by the assigning ratings organization. Each rating should be evaluated independently of any other rating.

Subject to the provisions of the indentures, we are permitted to create unrestricted subsidiaries, which will generally not be subject to any of the covenants in the indentures, and we may not be able to rely on the cash flow or assets of those unrestricted subsidiaries to pay our indebtedness.

Once formed in accordance with the provisions of the indenture governing the notes, unrestricted subsidiaries will not be subject to the covenants under the indentures, and their assets will not be available as security for the notes. Unrestricted subsidiaries may enter into financing arrangements that limit their ability to make loans or other payments to fund payments in respect of the notes. Accordingly, we may not be able to rely on the cash flow or assets of unrestricted subsidiaries to pay any of our indebtedness, including the notes.

The notes of each series were issued with original issue discount for U.S. federal income tax purposes.

Because the stated redemption price at maturity of each series of the notes exceeded the issue price of that series by more than a statutorily defined de minimis amount, both series of the notes are treated as having been issued with original issue discount for U.S. federal income tax purposes. As a result, in addition to the stated interest on the notes, a U.S. holder (as defined in “Certain United States Federal Tax Consequences”) is required to include such original issue discount in gross income as ordinary income as it accrues, in advance of the receipt of cash attributable to such income and regardless of such U.S. holder’s regular method of accounting for U.S. federal income tax purposes.

If a bankruptcy petition were filed by or against us under the U.S. Bankruptcy Code, the claim by any holder of the notes for the principal amount of the notes may be limited to an amount equal to the sum of:

• the original issue price for the notes; and

• that portion of the original issue discount (if any) that does not constitute “unmatured interest” for purposes of the U.S. Bankruptcy Code.

Any original issue discount that was not amortized as of the date of the bankruptcy filing would constitute unmatured interest. Accordingly, holders of the notes under these circumstances may receive a lesser amount than they would be entitled to receive under the terms of the indenture governing their notes, even if sufficient funds were available.

EXCHANGE OFFERS

Purpose and Effect of the Exchange Offers

At the closing of each offering of the old notes, we and the guarantors entered into registration rights agreements with the initial purchasers pursuant to which we and the guarantors agreed, for the benefit of the holders of each tranche of the old notes, at our cost, to do the following:

• file an exchange offer registration statement with the SEC with respect to the exchange offers for the new notes, and

• use commercially reasonable efforts to have each exchange offer completed on or before February 18, 2013.

Upon the SEC’s declaring the registration statement for the exchange offers effective, we agreed to offer the new notes in exchange for surrender of the old notes of the relevant tranche. We agreed to use commercially reasonable efforts to cause the registration statement for the exchange offers to be effective continuously, and to keep the exchange offers open for a period of not less than 20 business days.

For each old note surrendered to us pursuant to an exchange offer, the holder of such old note will receive a new note of the relevant tranche having a principal amount equal to that of the surrendered old note. Interest on each new note will accrue from the last interest payment date on which interest was paid on the surrendered old note. The registration rights agreements also provide an agreement to include in the prospectus for the exchange offers certain information necessary to allow a broker-dealer who holds old notes that were acquired for its own account as a result of market-making activities or other ordinary course trading activities (other than old notes acquired directly from us or one of our affiliates) to exchange such old notes pursuant to the applicable exchange offer and to satisfy the prospectus delivery requirements in connection with resales of new notes of the relevant tranche received by such broker-dealer in the applicable exchange offer. We agreed to use commercially reasonable efforts to maintain the effectiveness of the registration statement for the exchange offers for these purposes for a period ending on the earlier of 180 days from the date on which the registration statement for the exchange offers is declared effective and the date on which the broker-dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities.

The preceding agreement is needed because any broker-dealer who acquires old notes for its own account as a result of market-making activities or other trading activities is required to deliver a prospectus meeting the requirements of the Securities Act. This prospectus covers the offer and sale of the new notes pursuant to the applicable exchange offer and the resale of new notes received in the applicable exchange offer by any broker-dealer who held old notes of the relevant tranche acquired for its own account as a result of market-making activities or other trading activities, other than old notes of the relevant tranche acquired directly from us or one of our affiliates.

Based on interpretations by the staff of the SEC set forth in no-action letters issued to third parties, we believe that the new notes issued pursuant to the exchange offers would in general be freely tradable after the exchange offers without further registration under the Securities Act. However, any purchaser of old notes who is an “affiliate” of ours or who intends to participate in either exchange offer for the purpose of distributing the new notes of the relevant tranche:

• will not be able to rely on the interpretation of the staff of the SEC,

• will not be able to tender its old notes in the applicable 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 old notes unless such sale or transfer is made pursuant to an exemption from such requirements.

19

Each holder of the old notes (other than certain specified holders) who desires to exchange old notes for new notes of the relevant tranche in the applicable exchange offer will be required to make the representations described below under “—Procedures for Tendering—Your Representations to Us.”

We further agreed to file with the SEC a shelf registration statement to register for public resale old notes held by any holder who provides us with certain information for inclusion in the shelf registration statement if:

• the applicable exchange offer is not permitted by applicable law or SEC policy;

• the applicable exchange offer is for any reason not consummated on or before February 18, 2013 and the old notes of the relevant tranche are not freely tradeable prior to that date; or

• prior to February 18, 2013, any holder notifies us that:

• the holder is prohibited by applicable law or SEC policy from participating in the applicable exchange offer;

• the holder may not resell the new notes acquired in the applicable exchange offer to the public without delivering a prospectus, and the prospectus contained in the applicable exchange offer is not appropriate or available for such resales by such purchaser; or

• the holder is a broker-dealer and holds old notes acquired directly from us or one of our affiliates that are not freely tradeable, and such holder cannot participate in the applicable exchange offer.

We have agreed to use commercially reasonable efforts to cause the shelf registration statement to be declared effective by the SEC (or automatically become effective under the Securities Act) before a Registration Default (as defined below) occurs. We refer to the date the shelf registration statement is required to be filed as the “shelf filing deadline.” The shelf filing deadline shall be 20 business days after the later of (i) the date we receive notice of the above circumstances by any holder and (ii) the first to occur of (a) the date that we deliver the new notes to the registrar under the indenture of the new notes in the same aggregate principal amount as the aggregate principal amount of the old notes that were tendered by the holders of the old notes pursuant to an exchange offer and (b) February 18, 2013. We have also agreed to use commercially reasonable efforts to keep the shelf registration statement continuously effective from the date on which the shelf registration statement is declared effective by the SEC until the earlier of the first anniversary of the effective date of such shelf registration statement and such time as all notes covered by the shelf registration statement have been sold or are freely tradeable. We refer to this period as the “shelf effectiveness period.”

The registration rights agreements provide that, in the event (i) the applicable exchange offer is not consummated on or prior to February 18, 2013, (ii) the shelf registration statement, if required, is not declared effective (or does not automatically become effective) on or prior to the 180^th calendar day following any shelf filing deadline, or (iii) any required shelf registration statement ceases to remain effective or becomes unusable in connection with resale for more than 30 calendar days (each such event referred to in clauses (i) through (iii) above, a “Registration Default”), the interest rate on the old notes of the relevant tranche will be increased by 0.25% for the first 90-day period immediately following the occurrence of a Registration Default, and such rate will increase by an additional 0.25% per year with respect to each subsequent 90-day period, up to a maximum additional interest rate of 1.0% per year, until an Exchange Offer with respect to the applicable tranche of notes is completed or the shelf registration statement with respect to that tranche of notes becomes effective or is no longer required to be effective. All accrued additional interest will be paid by the Issuer and the Guarantors on the next scheduled interest payment date in the same manner as other interest is paid on the notes. Following the time that the notes are registered, the accrual of additional interest will cease.

Holders of the old notes will be required to make certain representations to us (as described in the registration rights agreements) in order to participate in the applicable exchange offer and will be required to deliver information to be used in connection with the shelf registration statement and to provide comments on the shelf registration statement within the time periods set forth in the registration rights agreement in order to have their old notes included in the shelf registration statement.

20

If we effect the exchange offers, we will be entitled to close each exchange offer 20 business days after its commencement as long as we have accepted all old notes validly tendered in accordance with the terms of the applicable exchange offer and no brokers or dealers continue to hold any old notes of the relevant tranche.

This summary of the material provisions of the registration rights agreements does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the registration rights agreements, copies of which are filed as an exhibit to the registration statement that includes this prospectus.

Except as set forth above, after consummation of each exchange offer, holders of old notes of the relevant tranche that are the subject of the applicable exchange offer will have no registration or exchange rights under the applicable registration rights agreement. Please read “—Consequences of Failure to Exchange.”

Terms of the Exchange Offers

Subject to the terms and conditions described in this prospectus and in the applicable letter of transmittal, we will accept for exchange any old notes properly tendered and not withdrawn prior to 11:59 p.m., New York City time, on the expiration date. We will issue new notes of the relevant tranche in a principal amount equal to the principal amount of old notes surrendered in the applicable exchange offer. Old notes may be tendered only for new notes of the relevant tranche and only in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The exchange offers are not conditioned upon any minimum aggregate principal amount of old notes of either tranche being tendered for exchange.

As of the date of this prospectus, $404,000,000 in aggregate principal amount of the old first priority notes is outstanding and $150,000,000 in aggregate principal amount of the old second priority notes is outstanding. This prospectus and the letter of transmittals are being sent to all registered holders of old notes. There will be no fixed record date for determining registered holders of old notes entitled to participate in the exchange offers.

We intend to conduct the exchange offers in accordance with the provisions of the applicable registration rights agreements, the applicable requirements of the Securities Act and the Exchange Act, and the rules and regulations of the SEC. Old notes that the holders thereof do not tender for exchange in the applicable exchange offer will remain outstanding and continue to accrue interest. These old notes will continue to be entitled to the rights and benefits such holders have under the indenture relating to the notes of the relevant tranche and the applicable registration rights agreement.

We will be deemed to have accepted for exchange properly tendered old notes when we have given oral or written notice of the acceptance to the exchange agent and complied with the applicable provisions of the applicable registration rights agreement. The exchange agent will act as agent for the tendering holders for the purposes of receiving the new notes from us.

If you tender old notes in the applicable exchange offer, you will not be required to pay brokerage commissions or fees or, subject to the letter of transmittal, transfer taxes with respect to the exchange of old notes. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the exchange offers. It is important that you read the section “—Fees and Expenses” for more details regarding fees and expenses incurred in connection with the applicable exchange offer.

We will return any old notes that we do not accept for exchange for any reason without expense to their tendering holder promptly after the expiration or termination of the applicable exchange offer.

21

Expiration Date

Each exchange offer will expire at 11:59 p.m., New York City time, on                    ,                    , unless, in our sole discretion, we extend it.

Extensions, Delays in Acceptance, Termination or Amendment

We expressly reserve the right, at any time or various times, to extend the period of time during which each exchange offer is open. We may extend such time for one exchange offer but not the other. We may delay acceptance of any old notes by giving oral or written notice of such extension to their holders at any time until the applicable exchange offer expires or terminates. During any such extensions, all old notes of the relevant tranche previously tendered will remain subject to the applicable exchange offer, and we may accept them for exchange.

In order to extend an exchange offer, we will notify the exchange agent orally or in writing of any extension. We will notify the registered holders of old notes of the relevant tranche of the extension no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date.

If any of the conditions described below under “—Conditions to the Exchange Offers” have not been satisfied, we reserve the right, in our sole discretion, to:

• delay accepting for exchange any old notes,

• extend either exchange offer, or

• terminate either exchange offer,

by giving oral or written notice of such delay, extension or termination to the exchange agent. Subject to the terms of the registration rights agreements, we also reserve the right to amend the terms of the exchange offers in any manner.

Any such delay in acceptance, extension, termination or amendment will be followed promptly by oral or written notice thereof to the registered holders of old notes. If we amend either exchange offer in a manner that we determine to constitute a material change, we will promptly disclose such amendment by means of a prospectus supplement. The prospectus supplement will be distributed to the registered holders of the old notes of the relevant tranche. Depending upon the significance of the amendment and the manner of disclosure to the registered holders, we may extend either exchange offer. In the event of a material change in the exchange offer, including the waiver by us of a material condition, we will extend the applicable exchange offer period, if necessary, so that at least five business days remain in the applicable exchange offer period following notice of the material change.

Conditions to the Exchange Offers

We will not be required to accept for exchange, or exchange any new notes for, any old notes if the applicable exchange offer, or the making of any exchange by a holder of old notes, would violate applicable law or any applicable interpretation of the staff of the SEC. Similarly, we may terminate either exchange offer as provided in this prospectus before accepting old notes of the relevant tranche for exchange in the event of such a potential violation.

In addition, we will not be obligated to accept for exchange the old notes of any holder that has not made to us the representations described under “—Purpose and Effect of the Exchange Offers,” “—Procedures for Tendering” and “Plan of Distribution” and such other representations as may be reasonably necessary under applicable SEC rules, regulations or interpretations to allow us to use an appropriate form to register the issuance of the new notes of the relevant tranche under the Securities Act.

22

We expressly reserve the right to amend or terminate each exchange offer, and to reject for exchange any old notes not previously accepted for exchange, upon the occurrence of any of the conditions to the applicable exchange offer specified above. We will give prompt oral or written notice of any extension, amendment, non-acceptance or termination to the holders of the old notes of the relevant tranche as promptly as practicable.

These conditions are for our sole benefit, and we may assert them or waive them in whole or in part at any time or at various times in our sole discretion prior to the expiration of the applicable exchange offer.

If we fail at any time to exercise any of these rights, this failure will not mean that we have waived our rights. Each such right will be deemed an ongoing right that we may assert at any time or at various times prior to the expiration of the applicable exchange offer.

In addition, we will not accept for exchange any old notes tendered, and will not issue new notes in exchange for any such old notes, if at such time any stop order has been threatened or is in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indentures relating to the notes under the Trust Indenture Act of 1939 (the “Trust Indenture Act”).

Procedures for Tendering

In order to participate in the applicable exchange offer, you must properly tender your old notes of the relevant tranche to the exchange agent as described below. We will only issue new notes in exchange for old notes of the relevant tranche that you timely and properly tender. Therefore, you should allow sufficient time to ensure timely delivery of the old notes, and you should follow carefully the instructions on how to tender your old notes. It is your responsibility to properly tender your notes. We have the right to waive any defects. However, we are not required to waive defects and are not required to notify you of defects in your tender.

If you have any questions or need help in exchanging your notes, please call the exchange agent, whose address and phone number are set forth in “Prospectus Summary—The Exchange Offers—Exchange Agent.”

All of the old notes were issued in book-entry form, and all of the old notes are currently represented by global certificates held for the account of DTC. We have confirmed with DTC that the old notes may be tendered using the Automated Tender Offer Program (“ATOP”) instituted by DTC. The exchange agent will establish an account with DTC for purposes of each of the exchange offers promptly after the commencement of the exchange offer, and DTC participants may electronically transmit their acceptance of the exchange offer by causing DTC to transfer their old notes to the exchange agent using the ATOP procedures. In connection with the transfer, DTC will send an “agent’s message” to the exchange agent. The agent’s message will state that DTC has received instructions from the participant to tender old notes and that the participant agrees to be bound by the terms of the applicable letter of transmittal.

By using the ATOP procedures to exchange old notes, you will not be required to deliver a letter of transmittal to the exchange agent. However, you will be bound by its terms just as if you had signed it.

There is no procedure for guaranteed late delivery of the notes.

Determinations Under the Exchange Offers

We will determine, in our sole discretion, all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered old notes and withdrawal of tendered old notes. Our determination will be final and binding. We reserve the absolute right to reject any old notes not properly tendered or any old notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defect, irregularities or conditions of tender as to particular old notes. Our interpretation of the terms and conditions of the exchange offers, including the instructions in the letter of transmittal, will be final and binding

23

on all parties. Unless waived, all defects or irregularities in connection with tenders of old notes must be cured within such time as we shall determine. Although we intend to notify holders of defects or irregularities with respect to tenders of old notes, neither we, the exchange agent nor any other person will incur any liability for failure to give such notification. Tenders of old notes will not be deemed made until such defects or irregularities have been cured or waived. Any old notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the tendering holder, unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration date of the exchange.

When We Will Issue New Notes

In all cases, we will issue new notes for old notes of the relevant tranche that we have accepted for exchange under the applicable exchange offer only after the exchange agent timely receives:

• a book-entry confirmation of such old notes into the exchange agent’s account at DTC; and

• a properly transmitted agent’s message.

Return of Old Notes Not Accepted or Exchanged

If we do not accept any tendered old notes for exchange or if old notes are submitted for a greater principal amount than the holder desires to exchange, the unaccepted or non-exchanged old notes will be returned without expense to their tendering holder. Such non-exchanged old notes will be credited to an account maintained with DTC. These actions will occur as soon as practicable after the expiration or termination of the applicable exchange offer.

Your Representations to Us

By agreeing to be bound by the letter of transmittal, you will represent to us that, among other things:

• any new notes that you receive will be acquired in the ordinary course of your business;

• you have no arrangement or understanding with any person or entity to participate in the distribution of the new notes;

• you are not our “affiliate,” as defined in Rule 405 of the Securities Act; and

• if you are a broker-dealer that will receive new notes for your own account in exchange for old notes of the relevant tranche, you acquired those notes as a result of market-making activities or other trading activities and you will deliver a prospectus (or, to the extent permitted by law, make available a prospectus) in connection with any resale of such new notes.

Withdrawal of Tenders

Except as otherwise provided in this prospectus, you may withdraw your tender at any time prior to 11:59 p.m., New York City time, on the expiration date. For a withdrawal to be effective, you must comply with the appropriate procedures of DTC’s ATOP system. Any notice of withdrawal must specify the name and number of the account at DTC to be credited with withdrawn old notes and otherwise comply with the procedures of DTC.

We will determine all questions as to the validity, form, eligibility and time of receipt of notice of withdrawal. Our determination shall be final and binding on all parties. We will deem any old notes so withdrawn not to have been validly tendered for exchange for purposes of the applicable exchange offer.

Any old notes that have been tendered for exchange but are not exchanged for any reason will be credited to an account maintained with DTC for the old notes. This crediting will take place as soon as practicable after

24

withdrawal, rejection of tender or termination of the applicable exchange offer. You may retender properly withdrawn old notes by following the procedures described under “—Procedures for Tendering” above at any time prior to 11:59 p.m., New York City time, on the expiration date of the exchange offer.

Fees and Expenses

We will bear the expenses of soliciting tenders. The principal solicitation is being made by mail; however, we may make additional solicitation by facsimile, telephone, electronic mail or in person by our officers and regular employees and those of our affiliates.

We have not retained any dealer-manager in connection with the exchange offers and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offers. We will, however, pay the exchange agent reasonable and customary fees for its services and reimburse it for its related reasonable out-of-pocket expenses.

We will pay the cash expenses to be incurred in connection with the exchange offers. They include:

• all registration and filing fees and expenses;

• all fees and expenses of compliance with federal securities and state “blue sky” or securities laws;

• accounting and legal fees, disbursements and printing, messenger and delivery services, and telephone costs; and

• related fees and expenses.

Transfer Taxes

We will pay all transfer taxes, if any, applicable to the exchange of old notes under the exchange offers. The tendering holder, however, will be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if a transfer tax is imposed for any reason other than the exchange of old notes under the exchange offers.

Consequences of Failure to Exchange

If you do not exchange new notes for your old notes of the relevant tranche under the applicable exchange offer, you will remain subject to the existing restrictions on transfer of the old notes. In general, you may not offer or sell the old notes unless the offer or sale is either registered under the Securities Act or exempt from registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreements, we do not intend to register resales of the old notes under the Securities Act.

Accounting Treatment

We will record the new notes in our accounting records at the same carrying value as the old notes of the relevant tranche. This carrying value is the aggregate principal amount of the old notes less any bond discount, as reflected in our accounting records on the date of exchange. Accordingly, we will not recognize any gain or loss for accounting purposes in connection with the exchange offers.

Other

Participation in the exchange offers is voluntary and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your own decision on what action to take.

We may in the future seek to acquire untendered old notes in open market or privately-negotiated transactions, through subsequent exchange offers or otherwise. We have no present plans to acquire any old notes that are not tendered in the exchange offers or to file a registration statement to permit resales of any untendered old notes.

25

RATIO OF EARNINGS TO FIXED CHARGES

The table below sets forth our ratio of earnings to fixed charges for the periods indicated on a consolidated historical basis. For purposes of computing the ratios of earnings to fixed charges, earnings consist of income (loss) from continuing operations before adjustment for equity income from equity method investees plus fixed charges, amortization of capitalized interest and distributed income from investees, and our share of pretax losses of investees for which charges arising from guarantees are included in fixed charges, each as accounted for under the equity method, less capitalized interest, preference security dividend requirements of consolidated subsidiaries, and the non-controlling interest in pre-tax income of subsidiaries that have not incurred fixed charges. Fixed charges consist of the sum of interest expensed and capitalized, plus amortized premiums, discounts and capitalized expenses related to indebtedness, an estimated interest component of rental expense, and preference security dividend requirements of consolidated subsidiaries.

	Endeavour International Corporation
	Year Ended December 31,										Nine Months Ended September 30, 2012
	2007		2008		2009		2010		2011
Ratio of earnings to fixed charges		—		2.7x		—		2.3x		—		—

For the year ended December 31, 2007, 2009 and 2011 and the nine months ended September 30, 2012, our ratio coverage was less than 1:1. To achieve ratio coverage of 1:1, we would have needed additional earnings of $78.7 million, $50.4 million, $118.6 million and $143.3 million, respectively.

26

USE OF PROCEEDS

The exchange offers are intended to satisfy our obligations under the registration rights agreements. We will not receive any proceeds from the issuance of the new notes in the exchange offers. In consideration for issuing the new notes as contemplated by this prospectus, we will receive old notes of the relevant tranche in a like principal amount. The form and terms of the new notes are identical in all respects to the form and terms of the old notes of the relevant tranche, except the new notes will be registered under the Securities Act and will not contain restrictions on transfer, registration rights or provisions for additional interest. Old notes surrendered in exchange for the new notes of the relevant tranche will be retired and cancelled and will not be reissued. Accordingly, the issuance of the new notes will not result in any change in outstanding indebtedness.

27

DESCRIPTION OF NOTES

You can find the definitions of certain terms used in this description under the subheading “—Certain Definitions.” In this description, the terms “Company,” “us,” “our” or “we” refer only to Endeavour International Corporation and not to any of its subsidiaries.

The Company previously issued (i) the 12% first priority notes due 2018 (the “old first priority notes”) under an indenture (the “first priority indenture”) among itself, the Guarantors and Wells Fargo Bank, National Association, as trustee (the “first priority trustee”) and (ii) the 12 % second priority notes due 2018 (the “old second priority notes” and together with the old first priority notes, the “old notes”) under an indenture (the “second priority indenture” and, together with the first priority indenture, the “indentures”) among itself, the Guarantors and Wilmington Trust, National Association, as trustee (“the second priority trustee” and, together with the first priority trustee, the “trustees”).

The Company will issue (i) the new 12% first priority notes due 2018 (the “new first priority notes”) under the first priority indenture and (ii) the new 12% second priority notes due 2018 (the “new second priority notes” and together with the new first priority notes, the “new notes”) under the second priority indenture. Wells Fargo Bank, National Association, serves as collateral agent with respect to the old and new first priority notes (in such capacity, the “first priority collateral agent”) and the old and new second priority notes (in such capacity, the “second priority collateral agent” and, together with the first priority collateral agent, the “collateral agents”). Unless the context indicates otherwise, references to the “notes” in this description are to the old notes and the new notes collectively. The terms of the notes include those stated in the indentures and those made part of the indentures by reference to the Trust Indenture Act of 1939.

The following description is a summary of the material provisions of the indentures, the notes, the Security Documents and the Intercreditor Agreement. This summary is not complete and is subject to, and qualified by reference to, all of the provisions of the indentures, the notes, the Security Documents and the Intercreditor Agreement. We urge you to read the indentures, the notes, the Security Documents and the Intercreditor Agreement because they, and not this description, define your rights as holders of the notes. Certain defined terms used in this description but not defined below under “—Certain Definitions” have the meanings assigned to them in the indentures.

The registered Holder of a note will be treated as the owner of it for all purposes. Only registered Holders will have rights under the applicable indenture.

If the exchange offers contemplated by this prospectus are consummated, holders of old notes who do not exchange those notes for new notes of the relevant tranche in the exchange offers will vote together with holders of new notes of the relevant tranche for all relevant purposes under the applicable indenture. In that regard, the indentures require that certain actions by the holders thereunder must be taken, and certain rights must be exercised, by specified minimum percentages of the aggregate principal amount of the outstanding securities issued under such indenture. In determining whether holders of the requisite percentage in principal amount have given any notice, consent or waiver or taken any other action permitted under the applicable indenture, any old notes that remain outstanding after the exchange offers will be aggregated with the new notes of the relevant tranche, and the holders of such old notes and the new notes of the relevant tranche will vote together as a single class for all such purposes under such indenture. Accordingly, all references herein to specified percentages in aggregate principal amount of the notes outstanding shall be deemed to mean, at any time after the exchange offers are consummated, such percentages in aggregate principal amount of the old notes and the new notes of the relevant tranche then outstanding.

Brief Description of the New Notes and the Subsidiary Guarantees

The New Notes.

The new first priority notes, like the old first priority notes:

• will be general senior obligations of the Company;

• will rank equally in right of payment with all existing and future senior Indebtedness of the Company;

• will rank effectively junior in right of payment to any Indebtedness of the Company secured by property other than the Collateral, to the extent of the value of the property securing such Indebtedness;

• will rank senior in right of payment to any future subordinated Indebtedness of the Company;

• will be effectively senior to the second priority notes and unsecured Indebtedness to the extent of the value of the Collateral;

• will be fully and unconditionally guaranteed, jointly and severally, by Endeavor Operating Corporation (“EOC”) on a senior first-priority secured basis (to the extent of the value of the Collateral pledged by EOC) and, subject to “—Security—General,” on a senior unsecured basis by the Company’s other Domestic Subsidiaries, as described below under “—The Subsidiary Guarantees”; and

• will rank effectively junior in right of payment to any Indebtedness or other liabilities (including trade payables) of the Company’s Subsidiaries that do not guarantee the notes.

The new second priority notes, like the old second priority notes:

• will be general senior obligations of the Company;

• will rank equally in right of payment with all existing and future senior Indebtedness of the Company;

• will rank effectively junior in right of payment to any Indebtedness of the Company secured by property other than the Collateral, to the extent of the value of the property securing such Indebtedness;

• will rank senior in right of payment to any future subordinated Indebtedness of the Company;

• will be effectively junior to the first priority notes to the extent of the value of the Collateral;

• will be fully and unconditionally guaranteed, jointly and severally, by EOC on a senior second-priority secured basis (to the extent of the value of the Collateral pledged by EOC) and on a senior unsecured basis by the Company’s other Domestic Subsidiaries, as described below under “—The Subsidiary Guarantees”; and

• will rank effectively junior in right of payment to any Indebtedness or other liabilities (including trade payables) of the Company’s Subsidiaries that do not guarantee the notes.

The Subsidiary Guarantees. The notes are guaranteed by all of the Company’s existing Domestic Subsidiaries, except for Endeavour Energy North Sea L.P. and Endeavour Energy North Sea LLC, two immaterial subsidiaries organized in Delaware. Endeavour Energy UK Limited (“EEUK”), Endeavour North Sea Limited, Endeavour Energy Luxembourg S.a.r.l. and the Company’s other existing Foreign Subsidiaries do not guarantee the notes. See “Risk Factors—Risks Related to an Investment in the New Notes—Claims of noteholders will be structurally subordinated to claims of creditors of any of our subsidiaries that do not guarantee the notes.”

Each guarantee of the new first priority notes, like each existing guarantee of the old first priority notes:

• will be a general senior obligation of the Guarantor,provided that the guarantee from EOC will be secured by a first-priority security interest in certain of its assets, as described below under “—Security”;

• in the case of the guarantee from each Guarantor other than EOC, will not initially be secured;

29

• will rank equally in right of payment with all existing and future senior Indebtedness of that Guarantor;

• in the case of the guarantee from EOC, will rank effectively senior to all unsecured Indebtedness of EOC and the guarantee from EOC of the second priority notes, in each case to the extent of the value of the Collateral securing that guarantee;

• will rank effectively junior in right of payment to any secured Indebtedness of that Guarantor secured by assets other than the Collateral, to the extent of the value of the assets securing such Indebtedness;

• will rank senior in right of payment to any future subordinated Indebtedness of that Guarantor; and

• will rank effectively junior in right of payment to any future Indebtedness or liabilities (including trade payables) of any Subsidiaries of that Guarantor that do not guarantee the first priority notes.

Each guarantee of the new second priority notes, like each existing guarantee of the old second priority notes:

• will be a general senior obligation of the Guarantor,provided that the guarantee from EOC will be secured Period by a second-priority security interest in certain of its assets, as described below under “—Security”;

• in the case of the guarantee from each Guarantor other than EOC, will not initially be secured;

• will rank equally in right of payment with all existing and future senior Indebtedness of that Guarantor;

• in the case of the guarantee from EOC, will rank effectively senior to all unsecured Indebtedness of EOC, and effectively junior to the guarantee from EOC of the first priority notes, in each case to the extent of the value of the Collateral securing that guarantee;

• will rank effectively junior in right of payment to any secured Indebtedness of that Guarantor secured by assets other than the Collateral, to the extent of the value of the assets securing such Indebtedness;

• will rank senior in right of payment to any future subordinated Indebtedness of that Guarantor; and

• will rank effectively junior in right of payment to any future Indebtedness or liabilities (including trade payables) of any Subsidiaries of that Guarantor that do not guarantee the second priority notes.

The loan by EOC to EEUK of substantially all the net proceeds of the old notes issued on February 23, 2012 was made pursuant to a subordinated revolving intercompany loan agreement that is subject to a first priority security interest in favor of the collateral agents as described under “—Security” (the “EEUK Loan”), which may be subordinated to any third-party financing of EEUK on such terms as the lenders may require.

The indentures permit the Company and its Subsidiaries to incur additional Indebtedness, including additional Senior Debt that may be secured to the extent permitted by the indentures. In particular, the Company is permitted to issue additional first priority notes and additional second priority notes, as well as Senior Debt that may be secured by assets that do not constitute collateral for any notes and is therefore effectively senior to the notes to the extent of the value of such assets. Furthermore, Subsidiaries that are not guarantors of the notes may issue Indebtedness that will be structurally senior to the notes, and such Indebtedness may be substantial.

Restricted Subsidiaries of the Company (including any newly created or acquired Restricted Subsidiaries of the Company) are required to guarantee the notes only under the circumstances described below under the subheading “—Certain Covenants—Additional Subsidiary Guarantees.” In the event of a bankruptcy, liquidation or reorganization of any non-guarantor Subsidiary, the non-guarantor Subsidiary will pay the holders of its debt and its trade creditors before it will be able to distribute any of its assets to the Company.

Currently, all of our Subsidiaries are “Restricted Subsidiaries.” However, under the circumstances described below under the subheading “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” we may designate certain of our Subsidiaries as “Unrestricted Subsidiaries.” Subsidiaries that own any Collateral

30

will at all times be required to be Restricted Subsidiaries. Our Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indentures and will not be required by the indentures to guarantee the notes.

Principal, Maturity and Interest

The Company has issued old first priority notes with an outstanding aggregate principal amount of $404 million and old second priority notes with an outstanding aggregate principal amount of $150 million. In addition to the new notes offered hereby, the Company may issue additional first priority notes and/or additional second priority notes under the applicable indenture from time to time after this offering. Any offering of additional notes would be subject to the covenants in the applicable indenture, including the covenants described below under the caption “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock” and “—Certain Covenants—Liens.” Any additional notes issued under the first priority indenture or the second priority indenture, together with the notes, will be treated as a single class with the old first priority notes or the old second priority notes, as the case may be, for all purposes under the applicable indenture and the related Security Documents and the Intercreditor Agreement, including, without limitation, waivers, amendments, redemptions and offers to purchase.

The Company may issue notes only in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The first priority notes will mature on March 1, 2018, and the second priority notes will mature on June 1, 2018.

Interest on the notes accrues at the rate of 12% per annum and is payable semi-annually in arrears on March 1 and September 1, with the next interest payment being due on March 1, 2013, and in the case of the second priority notes at final maturity, also. Interest on overdue principal and interest will accrue at a rate that is 1.0% higher than the then applicable interest rate on the notes. The Company will make each interest payment to the Holders of record on the immediately preceding February 15 and August 15, and in the case of the interest payment due on the final maturity date of the second priority notes, on the preceding May 15. Interest on the new notes will accrue from the date it was most recently paid.

Interest is computed on the basis of a 360-day year comprised of twelve 30-day months.

If an interest payment date falls on a day that is not a Business Day, the interest payment to be made on such interest payment date will be made on the next succeeding Business Day with the same force and effect as if made on such interest payment date, and no additional interest will accrue solely as a result of such delayed payment.

Methods of Receiving Payments on the Notes

If a Holder has given wire transfer instructions to the Company, the Company will pay all principal, interest and premium, if any, on that Holder’s notes in accordance with those instructions to an account in the United States. All other payments on the notes will be made at the office or agency of the paying agent and registrar within New York City (or, in the case of the second priority notes, within Wilmington, Delaware) unless the Company elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders.

Paying Agent and Registrar for the Notes

Each trustee is acting as paying agent and registrar with respect to the applicable notes. The notes may be presented for registration of transfer and exchange at the offices of the registrar. The Company may change the paying agent or registrar without prior notice to the Holders, and the Company or any of its Domestic Subsidiaries may act as paying agent or registrar.

31

Transfer and Exchange

A Holder may transfer or exchange notes in accordance with the applicable indenture. The applicable registrar or trustee may require a Holder to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. No service charge will be imposed by the Company, the trustees or the registrars for any registration of transfer or exchange of notes, but Holders will be required to pay all taxes due on transfer. 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.

Subsidiary Guarantees

Currently, all of our existing Material Domestic Subsidiaries guarantee the notes. In the future, certain Restricted Subsidiaries of the Company will be required to guarantee the notes under the circumstances described under “—Certain Covenants—Additional Subsidiary Guarantees.” The Subsidiary Guarantees are full and unconditional and joint and several obligations of the Guarantors. The indentures limit the obligations of each Guarantor under its Subsidiary Guarantee as necessary to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance under applicable law. It is uncertain, however, whether such provision will be effective under applicable law to prevent a Subsidiary Guarantee from being voidable as a fraudulent conveyance. See “Risk Factors—Risks Related to an Investment in the New Notes—Federal and state statutes allow courts, under specific circumstances, to void guarantees and require noteholders to return payments received from subsidiary guarantors.” Currently, none of the Company’s Foreign Subsidiaries is a Guarantor.

A Guarantor may not sell or otherwise dispose of, in one or more related transactions, all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor, unless:

(1) immediately after giving effect to such transaction or series of transactions, no Default or Event of Default exists under the applicable indenture;

(2) either:

(a) such Guarantor is the surviving Person or the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale or other disposition is made (such Guarantor or such Person, as the case may be, being herein called the “Successor Guarantor”) unconditionally assumes all the obligations of that Guarantor under the notes, the applicable indenture, its Subsidiary Guarantee and any Security Documents to which such Guarantor is a party pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the applicable trustee; or

(b) such transaction complies with the “Asset Sale” provisions of the applicable indenture;

(3) if applicable, the Successor Guarantor causes such amendments, supplements or other instruments to be executed, delivered, filed and recorded, as applicable, in such jurisdictions as may be required by applicable law to preserve and protect the Lien of the Security Documents on any Collateral owned by or transferred to the Successor Guarantor;

(4) any Collateral owned by or transferred to the Successor Guarantor shall (a) continue to constitute Collateral under the indentures and the Security Documents, (b) be subject to a first-priority Lien in favor of the first priority collateral agent for the benefit of the Holders of the first priority notes and a second-priority Lien in favor of the second priority collateral agent for the benefit of the Holders of the second priority notes, and (c) not be subject to any Lien other than Liens securing the notes; and

(5) the property and assets of the Person which is merged or consolidated with or into the Successor Guarantor, to the extent that they are property or assets of the types which would constitute Collateral under the Security Documents, shall be treated as after-acquired property and the Successor Guarantor shall take

32

such action as may be reasonably necessary to cause such property and assets to be made subject to a first-priority Lien in favor of the first priority collateral agent for the benefit of the Holders of the first priority notes and a second-priority Lien in favor of the second priority collateral agent for the benefit of the Holders of the second priority notes.

The Subsidiary Guarantee of a Guarantor will be released under each indenture:

(1) in connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition complies with the “Asset Sale” provisions of the indenture;

(2) in connection with any sale or other disposition of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition complies with the “Asset Sale” provisions of the indenture and the Guarantor no longer qualifies as a Subsidiary as a result of such disposition;

(3) if such Guarantor is a Restricted Subsidiary and the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of the indenture;

(4) upon legal defeasance of all notes outstanding under the indenture as described below under the caption “—Defeasance” or upon satisfaction and discharge of the applicable indenture;

(5) upon the liquidation or dissolution of such Guarantor provided no Default or Event of Default has occurred or is continuing; or

(6)(a) if such Guarantor is a Domestic Subsidiary, at such time as such Guarantor ceases (i) to guarantee any other Indebtedness of the Company or any other Guarantor in excess of the De Minimis Guaranteed Amount and (ii) to be a Material Domestic Subsidiary; and (b) if such Guarantor is a Foreign Subsidiary, at such time as such Guarantor ceases to guarantee any other Indebtedness of the Company or any other Guarantor in excess of the De Minimis Guaranteed Amount.

See “—Repurchase at the Option of Holders—Asset Sales.”

Security

General

The first priority indenture provides that the First Priority Notes Obligations will be secured by a first-priority security interest granted to the first priority collateral agent in:

(1) 65% of the voting Capital Stock and 100% of the non-voting Capital Stock of Endeavour International Holding B.V., and 65% of the voting Capital Stock and 100% of the non-voting Capital Stock of any other First-Tier Foreign Subsidiaries that EOC may thereafter acquire;

(2) any promissory notes or other Indebtedness owed by any Foreign Subsidiary to EOC (including the EEUK Loan); and

(3) all proceeds of, income and other payments (including, without limitation, dividends and distributions received) now or hereafter due and payable with respect to, and supporting obligations relating to, any and all of the foregoing.

The second priority indenture provides that the Second Priority Notes Obligations will be secured by a second-priority security interest granted to the second priority collateral agent in the collateral described in clauses (1), (2) and (3) of the previous paragraph.

In addition, each of the first priority indenture and the second priority indenture provides that, if the Company or any Domestic Subsidiary acquires Capital Stock of any First-Tier Foreign Subsidiary or any

33

promissory notes or other Indebtedness owed by any Foreign Subsidiary to the Company or such Domestic Subsidiary, then the Company or such Domestic Subsidiary, as applicable, will grant a first-priority and second-priority security interest to the first priority collateral agent and second priority collateral agent, respectively, in (1) 65% of the voting Capital Stock and 100% of the non-voting Capital Stock of such First-Tier Foreign Subsidiary, (2) such promissory notes or other Indebtedness and (c) all proceeds of, income and other payments (including, without limitation, dividends and distributions received) now or hereafter due and payable with respect to, and supporting obligations relating to, any and all of the foregoing.

The Company and its Subsidiaries may be able to issue from time to time additional first priority notes and second priority notes, which may be secured by Liens on the Collateral, subject to the priorities set forth in the Intercreditor Agreement. In connection with any enforcement action with respect to the Collateral or any insolvency or liquidation proceeding, all proceeds of the Collateral (after paying the fees and expenses of the collateral agents and any expenses of selling or otherwise foreclosing on the Collateral) will be applied first, pro rata to the repayment of the First Priority Notes Obligations, and second, pro rata to the repayment of the Second Priority Notes Obligations. The amount of such additional notes is limited by the covenants described under “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.” Under certain circumstances, the amount of such additional notes could be significant.

Moreover, the indentures provide that, if the Company or any Subsidiary grants a Lien on any assets or properties of the Company or any Subsidiary, or any income on profits therefrom, or assigns or conveys any right to receive income therefrom, to secure any first priority notes or second priority notes, the Company or such Subsidiary must secure all the notes or its Subsidiary Guarantee, as the case may be, with such assets or properties on the same basis as the initial Collateral, subject to the priorities set forth in the Intercreditor Agreement.

See “—Intercreditor Agreement” below, which sets forth a summary of certain rights and obligations of the Holders of the first priority notes and other First Priority Notes Obligations, on the one hand, and the holders of the second priority notes and other Second Priority Notes Obligations, on the other hand, with respect to the Collateral. The relative priorities of the security interests in the Collateral for the benefit of the holders of the first priority notes and the second priority notes, respectively, and the circumstances and manner in which the Collateral may be disposed of or otherwise realized following an Event of Default are described below under “—Intercreditor Agreement.” See “—Risk Factors—Risks Related to an Investment in the New Notes—The right of holders of second priority notes to exercise remedies with respect to the collateral is extremely limited, even during an event of default under the indenture governing the second priority notes.”

Security Documents

EOC and, to the extent required to grant a Lien in certain of their assets as described under “—General” above, the Company and the other Domestic Subsidiaries have entered into Security Documents with each collateral agent establishing the terms of the security interests and Liens contemplated by the indentures. These security interests secure the payment and performance when due of all of the Obligations, as provided in the Security Documents, subject to the priorities set forth in the Intercreditor Agreement.

So long as no Event of Default shall have occurred and be continuing, and subject to the terms of the Security Documents, EOC and, to the extent applicable, the Company and the other Domestic Subsidiaries, are entitled to exercise any voting and other consensual rights pertaining to the Collateral, including receipt of all payments made on the EEUK Loan. Upon the occurrence and during the continuance of an Event of Default, subject to the provisions of the Intercreditor Agreement:

(1) all of the rights of EOC and, to the extent applicable, the Company and the other Domestic Subsidiaries, to exercise voting or other consensual rights with respect to the Collateral will cease, and all such right will become vested in the applicable collateral agents, which, to the extent permitted by law, will have the sole right to exercise such voting and other consensual rights;

34

(2) all of the rights of EOC and, to the extent applicable, the Company and the other Domestic Subsidiaries, to receive cash dividends, interest and other payments made upon or with respect to the Collateral will cease and such cash dividends, interest and other payments will be paid to the collateral agents for application in accordance with the provisions of the applicable indenture and the priorities set forth in the Intercreditor Agreement; and

(3) the collateral agents may sell the Collateral or any part of the Collateral in accordance with the terms of the applicable Security Documents and the Intercreditor Agreement. The collateral agents, in accordance with the provisions of the applicable indenture and the Intercreditor Agreement, will distribute all funds distributed under the Security Documents and received by the collateral agents for the benefit of the Holders of the notes and any additional notes.

So long as both the first priority notes and the second priority notes are outstanding, the circumstances and manner in which the Collateral shall to the extent permitted by law be disposed of or otherwise realized following an Event of Default are described below under “—Intercreditor Agreement.”

The ability of a collateral agent to foreclose upon the Collateral is limited by applicable bankruptcy laws and by the terms of the Intercreditor Agreement. See “—Security—Certain Bankruptcy Limitations” and “—Intercreditor Agreement” below and “Risk Factors—Risks Related to an Investment in the New Notes—The ability of the collateral agents to foreclose on the collateral securing the guarantees may be limited pursuant to bankruptcy laws,” and “—The right of holders of second priority notes to exercise remedies with respect to the collateral is extremely limited, even during an event of default under the indenture governing the second priority notes.”

Release of Collateral

The first priority indenture provides that the Collateral securing the First Priority Notes Obligations will be released, subject to the provisions of the Intercreditor Agreement:

(1) in whole, upon the full and final payment and performance of all obligations under the first priority indenture, the first priority notes and the First Priority Security Documents;

(2) in the case of Capital Stock of a First-Tier Foreign Subsidiary, in connection with any sale or other disposition of all of the Capital Stock of that Subsidiary (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company in a transaction that is not prohibited by the first priority indenture, subject to compliance with the covenant described under the caption “—Repurchase at the Option of Holders—Asset Sales;”

(3) upon legal defeasance, covenant defeasance or satisfaction and discharge of the first priority notes as provided below under the captions “—Defeasance” and “—Satisfaction and Discharge;”

(4) as to any Collateral that constitutes all or substantially all of the Collateral, with the consent of the holders of 100% in principal amount of the first priority notes; or

(5) as to any Collateral other than Capital Stock of a First-Tier Foreign Subsidiary, in connection with any sale or other disposition of such Collateral to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company in a transaction that is not prohibited by the applicable indenture, subject to compliance with the covenant described under the caption “—Repurchase at the Option of Holders—Asset Sales.”

The second priority indenture provides that the Collateral securing the Second Priority Notes Obligations will be released, subject to the provisions of the Intercreditor Agreement:

(1) in whole, upon the full and final payment and performance of all obligations under the second priority indenture, the second priority notes and the Second Priority Security Documents;

35

(2) in the case of Capital Stock of a First-Tier Foreign Subsidiary, in connection with any sale or other disposition of all of the Capital Stock of that Subsidiary (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company in a transaction that is not prohibited by the second priority indenture, subject to compliance with the covenant described under the caption “—Repurchase at the Option of Holders—Asset Sales”;

(3) upon legal defeasance, covenant defeasance or satisfaction and discharge of the second priority notes as provided below under the captions “—Defeasance” and “—Satisfaction and Discharge”;

(4) as to any Collateral that constitutes all or substantially all of the Collateral, with the consent of the holders of 100% in principal amount of the second priority notes; or

(5) as to any Collateral other than Capital Stock of a First-Tier Foreign Subsidiary, in connection with any sale or other disposition of such Collateral to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company in a transaction that is not prohibited by the applicable indenture, subject to compliance with the covenant described under the caption “—Repurchase at the Option of Holders—Asset Sales.”

Sufficiency of Collateral

In the event of foreclosure on the Collateral, the proceeds from the sale of the Collateral may not be sufficient to satisfy in full the Obligations under the notes. The fair market value of the Collateral is subject to fluctuations based on factors that include, among others, the ability to sell the Collateral in an orderly sale, general economic conditions, the availability of buyers and similar factors. The amount to be received upon a sale of the Collateral would also be dependent on numerous factors, including, but not limited to, the actual fair market value of the Collateral at such time and the timing and the manner of the sale. In addition, there can be no assurance that the Collateral can be sold in a short period of time in an orderly manner. By its nature, portions of the Collateral may be illiquid and may have no readily ascertainable market value. In addition, in the event of a bankruptcy, the ability of the collateral agents to realize upon any of the Collateral may be subject to certain bankruptcy law limitations as described herein.

Certain Bankruptcy Limitations

The right of the collateral agents to repossess and dispose of the Collateral upon the occurrence of an Event of Default would be significantly impaired by applicable bankruptcy law in the event that a bankruptcy case were to be commenced by or against the Company, prior to a collateral agent having repossessed and disposed of the Collateral. Upon the commencement of a case for relief under Title 11 of the United States Code, as amended (the “Bankruptcy Code”), a secured creditor such as a collateral agent is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from the debtor, without prior bankruptcy court approval. Moreover, the Bankruptcy Code permits the debtor to continue to retain and use its security even though the debtor is in default under the applicable debt instrumentsprovided that the secured creditor is given adequate protection. The Intercreditor Agreement imposes significant limitations on the rights of the collateral agents in seeking any such bankruptcy court approval or adequate protection with respect to the Collateral. See “Intercreditor Agreements” and “Risk Factors—Risks Related to an Investment in the New Notes—The ability of the collateral agents to foreclose on the collateral securing the guarantees may be limited pursuant to bankruptcy laws.” The meaning of the term “adequate protection” may vary according to the circumstances, but it is intended in general to protect the value of the secured creditor’s interest in its security and may include cash payments or the granting of additional or replacement security, if and at such times as the court in its discretion determines, for any diminution in the value of such security as a result of the stay of any act by the secured creditor to repossess or dispose of such security or any use or sale of such security by the debtor during the pendency of the bankruptcy case. A bankruptcy court may determine that a secured creditor may not require compensation for any diminution in the value of such security if the value of such security exceeds the debt it secures.

36

In view of the broad equitable powers of a bankruptcy court and the restrictions on the rights of the collateral agents in the Intercreditor Agreement, it is impossible to predict how long payments under the notes or the guarantees could be delayed following commencement of a bankruptcy case involving the Company, whether or when the collateral agents could repossess or dispose of the Collateral, the value of the Collateral at the time of the bankruptcy petition or whether or to what extent Holders would be compensated for any delay in payment or loss of value of the Collateral through the requirement of “adequate protection” or what the ultimate distribution to the Holders would be on account of their claims under the notes. Any disposition of the Collateral during a bankruptcy case would also require permission from the bankruptcy court and could potentially be made over the Holders’ objection. Furthermore, in the event a bankruptcy court determines the value of the Collateral is not sufficient to repay all amounts due on the notes, the Holders would hold secured claims to the extent of the value of the Collateral to which the Holders are entitled, and unsecured claims with respect to such shortfall. The Bankruptcy Code only permits the payment and/or accrual of post-petition interest, costs and attorney’s fees and entitlement to “adequate protection” to a secured creditor during a debtor’s bankruptcy case to the extent the value of its security is determined by the bankruptcy court to exceed the aggregate outstanding principal amount of the obligations secured by such security.

In addition, the collateral agents’ ability to foreclose on the Collateral on behalf of Holders may be subject to lack of perfection, the consent of third parties, prior liens and practical problems associated with the realization of the collateral agents’ security interest in the Collateral.

Intercreditor Agreement

The first priority trustee, the first priority collateral agent, the second priority trustee and the second priority collateral agent are parties to an Intercreditor Agreement (as the same may be amended, supplemented or modified from time to time (together with any consent thereto executed by the Company or any Restricted Subsidiary), the “Intercreditor Agreement”).

Pursuant to the terms of the Intercreditor Agreement, the second priority collateral agent has agreed, on behalf of the holders of the Second Priority Notes Obligations, that the security interests created pursuant to the Second Priority Security Documents securing the Second Priority Notes Obligations are junior in priority, operation and effect to the security interests created pursuant to the First Priority Security Documents securing the First Priority Notes Obligations, notwithstanding any provisions of applicable law to the contrary, or the fact that the security interests in respect of the First Priority Notes Obligations are subordinated, voided, avoided, invalidated or lapsed.

Pursuant to the terms of the Intercreditor Agreement, prior to the Discharge of First Priority Notes Obligations, the first priority collateral agent, acting on behalf of the First Priority Secured Parties, will determine the time and method by which the security interests in the Collateral will be enforced and will have the sole and exclusive right to manage, perform and enforce the terms of the Security Documents relating to the Collateral and to exercise and enforce all privileges, rights and remedies thereunder according to its direction, including to take or retake control or possession of such Collateral and to hold, prepare for sale, marshal, process, sell, lease, dispose of or liquidate such Collateral;provided that the second priority collateral agent may exercise any or all such rights and remedies after a period (the “Standstill Period”) of 180 days from the date of delivery of written notice to the first priority collateral agent stating that the existence of any event of default as defined under the second priority indenture has occurred and is continuing thereunder as a result of which the second priority notes issued thereunder have been accelerated and stating its intention to exercise its rights to take such actions only so long as (a) no First Priority Secured Party has commenced (or attempted to commence or given notice of its intent to commence) the exercise of any of its rights or remedies with respect to the Collateral or any material portion thereof and (b) no insolvency or liquidation proceeding involving the Company or any Guarantor has commenced (the occurrence of any event described in clause (a) or (b) being a “Reversion Event”). The second priority collateral agent will not be permitted to enforce the security interests in the Collateral even if an event of default under the second priority indenture has occurred and the second priority

37

notes have been accelerated except (x) in any insolvency or liquidation proceeding, solely as necessary to file a proof of claim with respect to the Second Priority Notes Obligations, (y) as necessary to take any action (not adverse to the prior liens on the Collateral securing the First Priority Notes Obligations, or the rights of the first priority collateral agent or any First Priority Secured Party to exercise remedies in respect thereof) in order to prove, preserve, perfect or protect (but not enforce) its security interest and rights in, and the perfection and priority of its Lien on, the Collateral or to prove the validity and enforceability of the Second Priority Notes Obligations or (z) after termination of the Standstill Period (as long as no Reversion Event has occurred).

The second priority collateral agent, for itself and on behalf of each Second Priority Secured Party, has agreed pursuant to the Intercreditor Agreement that it will not (and thereby waives any right to) take any action to challenge, contest or support any other Person in contesting or challenging, directly or indirectly, in any proceeding (including any insolvency or liquidation proceeding), the validity, perfection, priority or enforceability of a Lien securing any First Priority Notes Obligations held (or purported to be held) by or on behalf of the first priority collateral agent or any of the First Priority Secured Parties or any agent or trustee therefor in any Collateral. The first priority collateral agent, for itself and on behalf of each First Priority Secured Party, will agree pursuant to the Intercreditor Agreement that it will not (and thereby waives any right to) take any action to challenge, contest or support any other Person in contesting or challenging, directly or indirectly, in any proceeding (including any insolvency or liquidation proceeding), the validity, perfection, priority or enforceability of a Lien securing any Second Priority Notes Obligations held (or purported to be held) by or on behalf of the second priority collateral agent or any of the Second Priority Secured Parties or any agent or trustee therefor in any Collateral.

In addition, the Security Documents provide that, prior to the Discharge of First Priority Notes Obligations, the first priority collateral agent may take actions with respect to the Collateral (including the release of Collateral and the manner of realization (subject to the provisions described under “—Release of Collateral”)) without the consent of the second priority collateral agent or other Second Priority Secured Parties.

The Collateral or proceeds thereof received in connection with the sale or other disposition of, or collection on, any Collateral will be applied to the First Priority Notes Obligations prior to application to any Second Priority Notes Obligations in such order as specified in the documents governing such First Priority Notes Obligations until the Discharge of First Priority Notes Obligations has occurred.

In addition, (a) neither the second priority collateral agent nor any Second Priority Secured Party shall acquire or hold any Lien on any assets of the Company or any Subsidiary (and neither the Company nor any Subsidiary shall grant such Lien) securing any Second Priority Notes Obligations that are not also subject to the First Priority Lien for the benefit of the First Priority Obligations under the First Priority Documents, and (b) neither the first priority collateral agent nor any First Priority Secured Party shall acquire or hold any Lien on any assets of the Company or any Subsidiary (and neither the Company nor any Subsidiary shall grant such Lien) securing any First Priority Notes Obligations that are not also subject to the Second Priority Lien for the benefit of the Second Priority Obligations under the Second Priority Documents.

If any First Priority Secured Party is required in any insolvency or liquidation proceeding or otherwise to turn over or otherwise pay to the estate of the Company or any other Guarantor (or any trustee, receiver or similar person therefor), because the payment of such amount was declared to be fraudulent or preferential in any respect or for any other reason, any amount (a “Recovery”), whether received as proceeds of security, enforcement of any right of setoff or otherwise, then as among the parties hereto, the First Priority Notes Obligations shall be deemed to be reinstated to the extent of such Recovery and to be outstanding as if such payment had not occurred and such First Priority Secured Party shall be entitled to a reinstatement of First Priority Notes Obligations with respect to all such recovered amounts and shall have all rights hereunder. If the Intercreditor Agreement shall have been terminated prior to such Recovery, the Intercreditor Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties thereto.

The Intercreditor Agreement provides that, so long as the Discharge of First Priority Notes Obligations has not occurred, whether or not any insolvency or liquidation proceeding has been commenced by or against the Company or any Guarantor, (i) neither the second priority collateral agent nor any Second Priority Secured Party will (but instead, each shall be deemed to have waived any right to) (x) exercise or seek to exercise any rights or remedies (including setoff or the right to credit bid debt (except under limited circumstances)) with respect to any collateral securing both the First Priority Notes Obligations and any Second Priority Notes Obligations in respect of any applicable Second Priority Notes Obligations, or institute any action or proceeding with respect to such rights or remedies (including any action of foreclosure);provided, that the second priority collateral agent may exercise any or all such rights and remedies after termination of the Standstill Period (as long as no Reversion Event has occurred), (y) contest, protest or otherwise object to any foreclosure or enforcement proceeding or action brought with respect to such collateral securing both the First Priority Notes Obligations and Second Priority Notes Obligations or any other collateral by the first priority collateral agent in respect of the First Priority Notes Obligations, the exercise of any right by the first priority collateral agent (or any agent or sub-agent on their behalf) in respect of the First Priority Notes Obligations under any control agreement, lockbox agreement, landlord waiver or bailee’s letter or similar agreement or arrangement to which the second priority collateral agent or any other Second Priority Secured Party either is a party or may have rights as a third-party beneficiary, or any other exercise by any such party of any rights and remedies as a secured party relating to such collateral or any other collateral under the First Priority Documents or otherwise in respect of First Priority Notes Obligations, or (z) object to any waiver or forbearance by the First Priority Secured Parties from or in respect of bringing or pursuing any foreclosure proceeding or action or any other exercise of any rights or remedies relating to such collateral or any other collateral in respect of First Priority Notes Obligations and (ii) except as otherwise provided in the Intercreditor Agreement (including after termination of the Standstill Period (as long as no Reversion Event has occurred)), the first priority collateral agent shall, on behalf of the First Priority Secured Parties have the sole and exclusive right to enforce rights, exercise remedies (including setoff and the right to credit bid their debt), marshal, process and make determinations regarding the release, disposition or restrictions, or waiver or forbearance of rights or remedies with respect to such collateral without any consultation with or the consent of the second priority collateral agent or any other Second Priority Secured Party, all as if first priority collateral agent held the only Lien in, on and to the Collateral.

In addition, the second priority collateral agent and each other Second Priority Secured Party have agreed, among other things, that if the Company or any Guarantor is subject to any insolvency or liquidation proceeding and the first priority collateral agent desires to permit the use of cash collateral or to permit the Company or any Guarantor to obtain financing under Section 363 or Section 364 of the Bankruptcy Code or any similar provision in any Bankruptcy Law (“DIP Financing”), including if such DIP Financing is secured by Liens senior in priority to the Liens securing the Second Priority Notes Obligations, then the second priority collateral agent and each Second Priority Secured Party, agrees not to object to such use of cash collateral or DIP Financing and will not request adequate protection or any other relief in connection therewith (except to the extent permitted by the Intercreditor Agreement) and, to the extent the Liens securing the First Priority Notes Obligations are subordinated orpari passu with such DIP Financing, will subordinate its Liens in the Collateral and any other collateral to such DIP Financing (and all Obligations relating thereto) on the same basis as they are subordinated to the First Priority Notes Obligations,provided that each Second Priority Secured Party shall be entitled to junior adequate protection of the same sort as a First Priority Secured Party.

The Holders of the Second Priority Notes Obligations may not take action or vote in any way that supports the confirmation or approval of any plan of reorganization that alters the provisions of the Intercreditor Agreement or grants such Holders or the second priority collateral agent any rights or benefits expressly prohibited by the Intercreditor Agreement.

Consistent with the relative priority of the rights set forth therein, the Intercreditor Agreement includes other provisions limiting the rights of the Second Priority Secured Parties in any insolvency or liquidation proceeding of the Company or any Guarantor, including limiting the right of the Second Priority Secured Parties to receive any reorganization securities in any reorganized entity by virtue of Liens in their favor on the Collateral absent a Discharge of the First Priority Notes Obligations.

39

Optional Redemption

Except as otherwise described below in this section or in the second to last paragraph under the caption “—Repurchase at the Option of the Holders—Change of Control,” the notes are not redeemable at the Company’s option prior to March 1, 2015. The Company is not, however, prohibited from acquiring the notes by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of the applicable indenture.

At any time prior to March 1, 2015 the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of first priority notes issued under the first priority indenture and/or, subject to limitations in the covenant described under the caption “—Restricted Payments,” up to 35% of the aggregate principal amount of second priority notes issued under the second priority indenture at a redemption price of 112.00% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), with the net cash proceeds of one or more bona fide Equity Offerings by the Company to non-Affiliates,provided that:

(1) at least 65% of the aggregate principal amount of such notes issued under the applicable indenture remains outstanding immediately after the occurrence of such redemption (excluding notes held by the Company and its Subsidiaries); and

(2) the redemption occurs within 180 days of the date of the closing of such Equity Offering.

On and after March 1, 2015, the Company may redeem (a) all or a part of the first priority notes and/or (b) subject to limitations in the covenant described under the caption “—Restricted Payments,” all or a part of the second priority notes, in each case upon notice pursuant to the applicable indenture at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the notes to be redeemed to the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), if redeemed during the twelve-month period beginning on March 15 of the years indicated below:

Year	Percentage
2015		106.000	%
2016		103.000	%
2017		100.000	%

In addition, prior to March 1, 2015, the Company may on any one or more occasions redeem (a) all or a part of the first priority notes and/or (b) subject to limitations in the covenant described under the caption “—Restricted Payments,” all or a part of the second priority notes, in each case at a redemption price equal to the sum of:

(1) the principal amount thereof, plus

(2) the Make Whole Premium at the redemption date, plus

accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

Selection and Notice

If less than all of the first priority notes or second priority notes are to be redeemed at any time, the applicable trustee will select notes for redemption as follows:

(1) if the notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the notes are listed; or

40

(2) if the notes are not listed on any national securities exchange, on a pro rata basis or, in the case of notes in global form, the applicable trustee will select notes for redemption based on DTC’s method that most nearly approximates a pro rata selection unless otherwise required by law.

No notes of $2,000 or less can be redeemed in part. Notices of optional redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of notes to be redeemed at its registered address, except that optional redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of notes or a satisfaction and discharge of the first priority indenture or the second priority indenture. Notice of any optional redemption, including, without limitation, upon an Equity Offering, may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of a related Equity Offering.

If any note is to be redeemed in part only, the notice of optional redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the applicable Holder upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption, unless a condition to the redemption set forth in the notice has not been satisfied. On and after the redemption date, interest ceases to accrue on notes or portions of them called for redemption, unless the Company defaults in making the redemption payment.

Mandatory Redemption

Except as set forth below under “—Repurchase at the Option of Holders,” the Company is not required to make mandatory redemption or sinking fund payments with respect to the notes or to repurchase the notes at the option of the Holders.

Repurchase at the Option of Holders

Change of Control

Each indenture provides that if a Change of Control occurs, each Holder of notes outstanding thereunder will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that Holder’s notes pursuant to an offer (“Change of Control Offer”) on the terms set forth in the applicable indenture. In the Change of Control Offer, the Company will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest, if any, on the notes repurchased, to the date of purchase (the “Change of Control Purchase Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Change of Control Purchase Date. Within 30 days following any Change of Control, the Company will mail a notice to each Holder and the applicable trustee describing the transaction or transactions that constitute the Change of Control and offering to repurchase notes properly tendered prior to the expiration date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the indentures and described in such notice.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the indentures, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the indentures by virtue of such compliance.

41

Promptly after the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer. Promptly thereafter on the Change of Control Purchase Date, the Company will:

(1) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and

(2) deliver or cause to be delivered to the applicable trustee the notes properly accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being purchased by the Company.

On the Change of Control Purchase Date, the paying agent will mail to each Holder of notes properly tendered the Change of Control Payment for such notes (or, if all the notes are then in global form, make such payment through the facilities of DTC), and the applicable trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any;provided, however, that each such new note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

The occurrence of a Change of Control may result in a default under existing or future Credit Facilities or other Indebtedness of the Company or its Subsidiaries and give the lenders thereunder the right to require the Company or its Subsidiaries to repay obligations outstanding thereunder. Moreover, the exercise by Holders of their right to require the Company to repurchase the notes could cause a default under such Indebtedness, even if the Change of Control itself does not, due to the financial effect of such repurchase on the Company. The Company’s ability to repurchase notes following a Change of Control also may be limited by the Company’s then existing financial resources. The indentures will provide that, prior to complying with any of the provisions of this “Change of Control” covenant, but in any event no later than the Change of Control Purchase Date, the Company or any Guarantor must either repay all of its other outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing such Senior Debt to permit the repurchase of notes required by this covenant. If the Company is unable to obtain the requisite consents or repay all of such other outstanding Senior Debt, the Company will remain prohibited from purchasing notes under those other agreements. The Company’s failure to purchase tendered notes would constitute an Event of Default under the indentures which could, in turn, constitute a default under other Indebtedness.

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

The Company will not be required to make a Change of Control Offer with respect to the first priority notes or the second priority notes upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the price, at the time and otherwise in compliance with the requirements set forth in the indentures applicable to a Change of Control Offer made by the Company and purchases all notes properly tendered and not withdrawn under the Change of Control Offer or (2) notice of redemption of all first priority notes and/or second priority notes, as the case may be, has been given pursuant to the applicable indenture as described above under the caption “—Optional Redemption” unless there is a default in payment of the applicable redemption price.

A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for such Change of Control at the time of making the Change of Control Offer.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of the Company and its

42

Restricted Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of notes to require the Company to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole to another Person or group may be uncertain.

Holders of notes may not be entitled to require us to purchase their notes in certain circumstances involving a significant change in the composition of our Board of Directors, including in connection with a proxy contest in which our Board of Directors does not approve a dissident slate of directors but approves them as Continuing Directors, even if our Board of Directors initially opposed the directors.

In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding notes of either tranche accept a Change of Control Offer and the Company (or the third party making the offer as provided above) purchases all of the notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all, but not less than all, of the notes of that tranche that remain outstanding following such purchase at a purchase price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on such notes that remain outstanding, to the date of redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date).

The Change of Control purchase feature of the notes may in certain circumstances make more difficult or discourage a sale or takeover of the Company and, thus, the removal of incumbent management. The Change of Control purchase feature is a result of negotiations between the Company and the initial purchasers. Subject to the limitations discussed below, the Company could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the indentures, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings. Restrictions on the Company’s ability to incur additional Indebtedness are contained in the covenant described under “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.” Such restrictions in each indenture can be waived only with the consent of the Holders of a majority in principal amount of the notes then outstanding under such indenture. Except for the limitations contained in such covenant, however, the indentures do not contain any covenants or provisions that may afford Holders of the notes protection in the event of a highly leveraged transaction.

Asset Sales

The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at least equal to the Fair Market Value of the assets or Equity Interest issued or sold or otherwise disposed of; and

(2) (i) other than with respect to Collateral Dispositions, at least 75% of the aggregate consideration to be received by the Company and its Restricted Subsidiaries in such Asset Sale (determined on the date of contractually agreeing to such Asset Sale) and any other Asset Sale (other than Collateral Dispositions) since the date of the applicable indenture, on a cumulative basis, is in the form of cash or Cash Equivalents and (ii) with respect to Collateral Dispositions, 100% of the consideration to be received by the Company or its Restricted Subsidiaries in such Asset Sale is in the form of cash. For purposes of this provision, except with respect to a Collateral Disposition, each of the following will be deemed to be cash:

(a) any liabilities, as shown on the Company’s or any Restricted Subsidiary’s most recent balance sheet, of the Company or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated in right of payment to the notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; and

43

(b) any securities, notes or other obligations received by the Company or any Restricted Subsidiary from such transferee that are, within 90 days after the Asset Sale, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash received in that conversion;provided that in the case of any Asset Sale pursuant to a condemnation, appropriation or similar governmental taking, including by deed in lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of items (1) and (2) above. Notwithstanding the preceding, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the preceding provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale other than a Collateral Disposition, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply those Net Proceeds (except for Specified Asset Sale Proceeds that constitute Excess Proceeds) at its option to any combination of the following:

(1) to permanently prepay, repay, redeem, defease or purchase secured Senior Debt (in the case of the second priority notes, subject to limitations in the covenant described under the caption “—Restricted Payments”);

(2) to invest in or acquire Additional Assets; or

(3) to make capital expenditures in respect of the Company’s or its Restricted Subsidiaries’ Oil and Gas Business.

The requirement of clause (2) or (3) of the preceding paragraph shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Company within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such contract within six months following the date such agreement is entered into.

Pending the final application of any Net Proceeds, the Company or any Restricted Subsidiary of the Company may invest the Net Proceeds in any manner that is not prohibited by the indentures. “Excess Proceeds” consist of any (i) Net Proceeds from Asset Sales other than Collateral Dispositions that are not applied or invested as provided in the preceding paragraph or (ii) Specified Asset Sale Proceeds in excess of $100 million, to the extent of such excess.

When the aggregate amount of Net Proceeds from all Collateral Dispositions (“Collateral Net Proceeds”) exceeds $10 million, the Company shall, within 60 days following the date on which such Collateral Net Proceeds first exceed such amount, use all Collateral Net Proceeds to make an offer (the “First Priority Collateral Sale Offer”) to all Holders of first priority notes to purchase, on a pro rata basis, the maximum principal amount of first priority notes that may be purchased out of the Collateral Net Proceeds. After the completion of any First Priority Collateral Sale Offer, if there are any remaining Collateral Net Proceeds in excess of $10 million, the Company shall, within 60 days following the consummation of such First Priority Collateral Sale Offer, use all remaining Collateral Net Proceeds to make an offer (the “Second Priority Collateral Sale Offer”) to all Holders of second priority notes, to purchase, on a pro rata basis, the maximum principal amount of second priority notes that may be purchased out of such remaining Collateral Net Proceeds. The offer price in any First Priority Collateral Sale Offer or Second Priority Collateral Sale Offer (each a “Collateral Sale Offer”) will be equal to 100% of principal amount plus accrued and unpaid interest, if any, to the date of settlement, subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of settlement, and will be payable in cash.

44

If the aggregate principal amount of first priority notes or second priority notes tendered into a Collateral Sale Offer exceeds the amount of Collateral Sale Proceeds allocated for the purchase of the first priority notes or second priority notes, as the case may be, the applicable trustee will select the notes to be purchased on a pro rata basis or, in the case of notes in global form, the applicable trustee will select notes for redemption based on DTC’s method that most nearly approximates a pro rata selection unless otherwise required by law. If any Collateral Net Proceeds remain after consummation of a First Priority Collateral Sale Offer and (if applicable) corresponding subsequent Second Priority Sale Offer, the Company may use those proceeds for any purpose not otherwise prohibited by the indentures. Upon completion of each First Priority Collateral Sale Offer and (if applicable) corresponding subsequent Second Priority Sale Offer, the amount of Collateral Net Proceeds will be reset at zero.

On the 366th day after an Asset Sale other than a Collateral Disposition (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $10 million, the Company will make an offer (the “Asset Sale Offer”) to all Holders of first priority notes and, subject to limitations in the covenant described under the caption “—Restricted Payments,” second priority notes, as well as all holders of other Indebtedness that ispari passu with the notes containing provisions similar to those set forth in the indentures with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase, on a pro rata basis, the maximum principal amount of notes and such otherpari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest, if any, to the date of settlement, subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of settlement, and will be payable in cash. If the aggregate principal amount of notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds allocated for the purchase of the first priority notes or second priority notes, as the case may be, the applicable trustee will select the notes to be purchased on a pro rata basis or, in the case of notes in global form, the applicable trustee will select notes for redemption based on DTC’s method that most nearly approximates a pro rata selection unless otherwise required by law. If any Excess Proceeds remain after consummation of such an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the indentures. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of notes pursuant to an Asset Sale Offer or Collateral Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the indentures, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of the indentures by virtue of such compliance.

The Company’s ability to repurchase notes in an Asset Sale Offer or Collateral Sale Offer may be restricted under existing or future Credit Facilities or other Indebtedness of the Company or its Subsidiaries and give the lenders thereunder the right to require the Company or its Subsidiaries to repay obligations outstanding thereunder. Moreover, the exercise by Holders of their right to require the Company to repurchase notes could cause a default under such Credit Facilities or other Indebtedness, even if the Asset Sale Offer or Collateral Sale Offer itself does not, due to the financial effect of such repurchase on the Company. The Company’s ability to repurchase notes in an Asset Sale Offer or Collateral Sale Offer also may be limited by the Company’s then-existing financial resources. The indentures will provide that, prior to complying with any of the provisions of this “Asset Sales” covenant, but in any event no later than the date of the Asset Sale Offer or Collateral Sale Offer, the Company or any Guarantor must either repay all of its other outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing such Senior Debt to permit the repurchase of notes required by this covenant. If the Company is unable to obtain the requisite consents or repay all of such other outstanding Senior Debt, the Company will remain prohibited from purchasing notes under those other agreements. The Company’s failure to purchase tendered notes would constitute an Event of Default under the indentures which could, in turn, constitute a default under other Indebtedness.

45

Certain Covenants

Effectiveness of Covenants

From and after the first day (the “Suspension Date”) on which:

(1) the notes of either tranche have an Investment Grade Rating from both Rating Agencies; and

(2) no Default has occurred and is continuing under the applicable indenture;

the Company and its Restricted Subsidiaries will not be subject to the provisions of the applicable indenture summarized above under the subheading “—Repurchase at the Option of Holders—Asset Sales” and under the following subheadings:

(1) “—Restricted Payments,”

(2) “—Incurrence of Indebtedness and Issuance of Preferred Stock,”

(3) “—Dividend and Other Payment Restrictions Affecting Subsidiaries,”

(4) Clause (4) of “—Merger, Consolidation or Sale of Assets”

(5) “—Transactions with Affiliates,” and

(6) “—Business Activities.”

(collectively, the “Suspended Covenants”). If at any date (each such date, a “Reversion Date”) the credit rating of the notes of such tranche is downgraded from an Investment Grade Rating by either Rating Agency or a Default (other than with respect to the Suspended Covenants) occurs and is continuing, then the Suspended Covenants will thereafter be reinstated and again be applicable pursuant to the terms of the applicable indenture. The period of time between the Suspension Date and the Reversion Date is referred to herein as the “Suspension Period.” During any Suspension Period, such notes will be entitled to substantially reduced covenant protection. Neither the failure of the Company or any of its Subsidiaries to comply with a Suspended Covenant during a Suspension Period nor compliance by the Company or any of its Subsidiaries with any contractual obligation entered into in compliance with the applicable indenture during that period will constitute a Default, Event of Default or breach of any kind under the applicable indenture, the notes thereunder or the related Subsidiary Guarantees.

The Board of Directors of the Company may not designate any of the Company’s Subsidiaries as Unrestricted Subsidiaries pursuant to the applicable indenture during any Suspension Period.

Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under “—Restricted Payments” will be made as though the covenant described under “—Restricted Payments” had been in effect at all times since the Issue Date, including during the Suspension Period.

There can be no assurance that either the first priority notes or the second priority notes will ever achieve or maintain an Investment Grade Rating from any Rating Agency.

Restricted Payments

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or payable to the Company or a Restricted Subsidiary of the Company);

46

(2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company;

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated in right of payment to the notes or any Subsidiary Guarantee (excluding (a) any intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries, (b) the purchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness that is subordinated in right of payment to the notes or the Subsidiary Guarantees purchased, redeemed, defeased or otherwise acquired or retired for value in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, redemption, defeasance or other acquisition or retirement for value, and (c) any payment of principal or interest at the Stated Maturity thereof);

(4) make any Restricted Investment; or

(5) for purposes of the first priority indenture only, make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any second priority notes (other than (a) at the Stated Maturity thereof or (b) pursuant to a Change of Control Offer or a Second Priority Collateral Sale Offer) or Specified Junior Debt Issuances (other than at the Stated Maturity thereof or pursuant to an Asset Sale Offer) (all such payments and other actions set forth in these clauses (1) through (5) being collectively referred to as “Restricted Payments”);

unless, at the time of and after giving effect to such Restricted Payment, no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment and:

(I) the Company would, at the time of such Restricted Payment immediately after giving pro forma effect thereto as if the same had occurred at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of the covenant described below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”; and

(II) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (8), (9), (11) and (12) of the next succeeding paragraph) since the date of the applicable indenture, is less than the sum, without duplication, of:

(a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the Measurement Date to the last day of the Company’s last fiscal quarter ending prior to the date of the Restricted Payment for which internal financial statements are in existence at the time of such Restricted Payment (or, if such Consolidated Net Income for such period shall be a loss, minus 100% of such loss); plus

(b) 100% of the aggregate net cash proceeds, and the Fair Market Value of any Capital Stock of Persons (other than the Company or an Affiliate of the Company) engaged primarily in the Oil and Gas Business or any other assets that are used or useful in the Oil and Gas Business, in each case received by the Company after the date of the applicable indenture as a contribution to its common equity capital or from the issue or sale after the date of the applicable indenture of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale after the date of the applicable indenture of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company) or received upon the exercise of any options, warrants or rights to purchase Equity Interests (other than Disqualified Stock) of the Company, plus

The amount of all Restricted Payments (other than cash) will be the Fair Market Value, on the date of the Restricted Payment, of the Restricted Investment proposed to be made or asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment, except that the amount of any non-cash Restricted Payment referred to in the preceding clause (1) will be the Fair Market Value on the date of declaration. The Fair Market Value of any assets or securities that are required to be valued by this covenant will be determined by the method prescribed in the definition of such term, except that the Fair Market Value of any non-cash consideration received from an Affiliate as a capital contribution for Equity Interests of the Company shall be determined in good faith by the Board of Directors of the Company in the case of amounts of $10 million or more, such determination to be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing. For purposes of determining compliance with this “Restricted Payments” covenant, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in the preceding clauses (1)-(12) or as a Permitted Investment, the Company will be permitted to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this covenant.

Incurrence of Indebtedness and Issuance of Preferred Stock

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness, the Company will not issue any Disqualified Stock, and the Company will not permit any of its Restricted Subsidiaries to issue any Disqualified Stock or preferred securities;provided, however, that the Company and any Guarantor may incur Indebtedness other than Specified Additional First Priority Notes, the Company may issue Disqualified Stock and any Guarantor may issue Disqualified Stock or preferred securities, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such preferred securities or Disqualified Stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or such preferred securities or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period.

50

The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any Disqualified Stock or any preferred securities described below (collectively, “Permitted Debt”):

(1) the incurrence by the Company or any of the Restricted Subsidiaries of additional Indebtedness under one or more Credit Facilities,provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness outstanding under the Company and its Restricted Subsidiaries’ Credit Facilities incurred under this clause (1) does not exceed:

(a) if the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence are $2.0 billion or less, the greater of (i) $100 million and (ii) 7.5% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of such date;

(b) if the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence are $3.0 billion or less, but exceed $2.0 billion, the greater of (i) $100 million and (ii) 10% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of such date; and

(c) if the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence exceed $3.0 billion, the greater of (i) $100 million and (ii) 15% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of such date;

(2) the incurrence by the Company or its Restricted Subsidiaries of the Existing Indebtedness not otherwise referred to in this definition of “Permitted Debt”;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which shall be used to extend, refinance, renew, replace, defease, discharge, refund or otherwise retire for value, in whole or in part, Indebtedness of the Company or any of its Restricted Subsidiaries (other than intercompany Indebtedness) or Disqualified Stock of the Company, in each case that was permitted by the applicable indenture to be incurred pursuant to the first paragraph of this covenant or clauses (2), (3) and (12) of this paragraph or this clause (5);

(6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among any of the Company and any of its Restricted Subsidiaries;provided, however, that:

(a) if the Company is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the notes, or if a Guarantor is the obligor on such Indebtedness and neither the Company nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Subsidiary Guarantee of such Guarantor;

51

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an incurrence (as of the date of such issuance, sale or transfer) of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); and

(c) if a Foreign Subsidiary is the obligor on such Indebtedness and the Company or a Domestic Subsidiary is the obligee, such Indebtedness must be evidenced by a promissory note or other instrument or agreement that is pledged in favor of the collateral agents pursuant to the Security Documents;

(7) the incurrence by the Company or any of its Restricted Subsidiaries of obligations under Hedging Contracts;

(9) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness relating to net gas balancing positions arising in the ordinary course of business and consistent with past practice;

(10) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance, surety, appeal and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business or which are customary in the Oil and Gas Business;

(11) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any preferred securities;provided, however, that: (a) any subsequent issuance or transfer of Equity Interests that results in any such preferred securities being held by a Person other than the Company or a Restricted Subsidiary of the Company and (b) any sale or other transfer of any such preferred securities to a Person that is not either the Company or a Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an issuance (as of the date of such issuance, sale or transfer) of such preferred securities by such Restricted Subsidiary that was not permitted by this clause (11);

(12) Permitted Acquisition Indebtedness;

(13) the incurrence by the Company or its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds in the ordinary course of business, so long as such Indebtedness is covered within five Business Days;

(14) the incurrence by the Company or its Restricted Subsidiaries of Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and the Restricted Subsidiaries; and

(15) the incurrence by the Company or any Guarantor of additional Indebtedness other than Additional Priority Debt or the issuance by the Company of additional Disqualified Stock or the issuance by any Guarantor of preferred securities,provided that, after giving effect to any such incurrence or issuance, the aggregate principal amount of all Indebtedness, Disqualified Stock and preferred securities incurred or issued under this clause (15) and then outstanding does not exceed the greater of (a) $75 million and (b) 5.0% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance.

52

For purposes of determining compliance with this “Incurrence of Indebtedness and Issuance of Preferred Stock” covenant, in the event that an item of Indebtedness or Disqualified Stock or preferred securities meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (15) above, or is entitled to be incurred or issued pursuant to the first paragraph of this covenant, the Company will be permitted to divide and classify (or later classify, reclassify or re-divide in whole or in part in its sole discretion) such item of Indebtedness or Disqualified Stock or preferred securities in any manner that complies with this covenant, subject to the limitations specified in the definition of “Existing Indebtedness.” For purposes of determining any particular amount of Indebtedness under this covenant, guarantees of Indebtedness otherwise included in the determination of such amount shall not also be included except to the extent that such Indebtedness exceeds such guarantee.

The accrual of interest, accrual of dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness and the payment of dividends on Disqualified Stock or preferred securities in the form of additional shares of Disqualified Stock or preferred securities will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred securities for purposes of this covenant.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency will be calculated based on the relevant currency exchange rate in effect on the date the Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness;provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and the refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of the refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced (plus all accrued and unpaid interest on such Indebtedness, and the amount of all fees, expenses and premiums incurred in connection therewith). Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, will be calculated based on the currency exchange rate applicable to the currencies in which the Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Liens

The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective (a) any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets other than the Collateral (whether now owned or hereafter acquired), unless the notes or (in the case of such a Lien with respect to a Guarantor) the applicable Subsidiary Guarantee is secured on an equal and ratable basis with (or, in the case of obligations subordinated in right of payment to the notes or such Subsidiary Guarantee, as the case may be, on a basis senior (to at least the same extent as the notes are senior in right of payment) to) the obligations so secured until such time as such obligations are no longer secured by a Lien or (b) any Lien of any kind securing Indebtedness upon any of the Collateral (whether now owned or hereafter acquired), other than the notes.

Any Lien on any property or assets of the Company or any of its Restricted Subsidiaries created for the benefit of the Holders of the notes pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged at such time as there are no other Liens of any kind (other than Permitted Liens) on such property or assets securing Indebtedness.

53

Dividend and Other Payment Restrictions Affecting Subsidiaries

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to:

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any Indebtedness or other obligations owed to the Company or any of its Restricted Subsidiaries;

(2) make loans or advances to the Company or any of its Restricted Subsidiaries; or

(3) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

(1) agreements (including those governing Existing Indebtedness) as in effect on the date of the applicable indenture and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof;provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the date of the applicable indenture, as determined by the Board of Directors of the Company in its reasonable and good faith judgment;

(2) the indentures, the notes, the Security Documents, the Intercreditor Agreement and the Subsidiary Guarantees;

(3) applicable law, rule, regulation or regulatory order, approval, license, permit or similar restriction;

(5) any agreement or instrument governing any Permitted Acquisition Indebtedness, so long as such agreement or instrument (A) was not entered into in contemplation of the acquisition, merger or consolidation transaction related thereto, and (B) is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the properties or assets or Subsidiaries of the Person, subject to such acquisition, merger or consolidation, so long as the agreement containing such restriction does not violate any other provision of the applicable indenture;

(6) instruments or agreements governing Indebtedness of the Company or any of the Restricted Subsidiaries permitted to be incurred pursuant to an instrument or agreement entered into subsequent to the date of the applicable indenture in accordance with the covenant described under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”;provided that either (a) the encumbrance or restriction contained in the instrument or agreement governing such Indebtedness applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (b) the Board of Directors of the Company determines in good faith that any such encumbrance or restriction will not materially affect the Company’s ability to make principal or interest payments on the notes;

(7) (i) customary non-assignment provisions in Hydrocarbon purchase and sale or exchange agreements, joint operating agreements, or similar operational agreements or in licenses or leases entered into in the ordinary course of business, or (ii) in the case of clause (3) of the preceding paragraph, other encumbrances or restrictions in agreements or instruments (including joint venture agreements, asset sale agreements, stock sale agreements and agreements of the type described in the definition of “Permitted

54

Business Investments”) relating to specific assets or property (and not to Indebtedness) that restrict generally the transfers of such assets or property,provided, however, that such other encumbrances or restrictions do not materially impair the ability of the Company to make scheduled payments on the notes when due and in each case entered into in the ordinary course of business or customary in the Oil and Gas Business;

(8) Capital Lease Obligations, mortgage financings or purchase money obligations, in each case for property acquired in the ordinary course of business or which is customary in the Oil and Gas Business that impose restrictions on that property purchased or leased of the nature described in clause (3) of the preceding paragraph;

(9) any agreement for the sale or other disposition of a Restricted Subsidiary of the Company that restricts distributions by that Restricted Subsidiary pending its sale or other disposition;

(10) Permitted Refinancing Indebtedness,provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced, as determined by the Board of Directors of the Company in its reasonable and good faith judgment;

(11) Liens securing Indebtedness otherwise permitted to be incurred under the provisions of the covenant described above under the caption “—Liens” that limit the right of the debtor to dispose of the assets subject to such Liens;

(12) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers or lessors under contracts or leases entered into in the ordinary course of business or which are customary in the Oil and Gas Business;

(13) Hedging Contracts permitted from time to time under the applicable indenture;

(14) any subordination of intercompany Indebtedness or other intercompany obligations (including any intercompany revolving credit) to the claims or Liens (otherwise permitted by the applicable indenture) of any other creditor of the obligor or obligors of such intercompany Indebtedness or other obligations, including to the claims or Liens (otherwise permitted by the applicable indenture) of any lender or other party to any Credit Facility (as a lender, letter of credit issuer or in any other capacity); and

(15) the issuance of preferred securities by a Restricted Subsidiary of the Company or the payment of dividends thereon in accordance with the terms thereof;provided that issuance of such preferred securities is permitted pursuant to the covenant described under “—Incurrence of Indebtedness and Issuance of Preferred Stock” and the terms of such preferred securities do not expressly restrict the ability of a Restricted Subsidiary of the Company to pay dividends or make any other distributions on its Equity Interests (other than requirements to pay dividends or liquidation preferences on such preferred securities prior to paying any dividends or making any other distributions on such other Equity Interests).

The Company may not: (x) consolidate or merge with or into another Person (whether or not the Company is the survivor), convert into another form of entity or continue in another jurisdiction; or (y) directly or indirectly, sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless:

(1) either: (a) the Company is the survivor; or (b) the Person formed by or surviving any such consolidation or merger or resulting from such conversion (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the United States, any state of the United States or the District of Columbia (the Company or such Person, as the case may be, being herein called the “Successor Company”);

(b) immediately after giving pro forma effect to such transaction and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, the Fixed Charge Coverage Ratio of the Successor Company will be equal to or greater than the Fixed Charge Coverage Ratio of the Company immediately prior to such transaction;

(8) the property and assets of the Person which is merged or consolidated with or into the Successor Company, to the extent that they are property or assets of the types which would constitute Collateral under the Security Documents, shall be treated as after-acquired property and the Successor Company shall take such action as may be reasonably necessary to cause such property and assets to be made subject to a first-priority Lien in favor of the first priority collateral agent for the benefit of the Holders of the first priority notes and a second-priority Lien in favor of the second priority collateral agent for the benefit of the Holders of the second priority notes.

Notwithstanding the restrictions described in the foregoing clause (4), (x) any Restricted Subsidiary of the Company may consolidate with, merge into or dispose of all or part of its properties or assets to the Company or another Restricted Subsidiary, and (y) the Company may merge with or into an Affiliate formed solely for the purpose of reincorporating the Company in another jurisdiction, and the Company will not be required to comply with the preceding clause (5) in connection with any such consolidation, merger or disposition.

For purposes of the foregoing, the sale, assignment, transfer, lease, conveyance or other disposition (in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Subsidiaries of the Company, which properties or assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties or assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties or assets of the Company.

Upon any consolidation or merger or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of the Company in accordance with the foregoing in which the

56

Company is not the surviving entity, the surviving entity formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the applicable indenture with the same effect as if such surviving entity had been named as the Company in the applicable indenture, and thereafter (except in the case of a lease of all or substantially all of the Company’s properties or assets), the Company will be relieved of all obligations and covenants under the applicable indenture and the first priority notes and/or second priority notes, as the case may be.

Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances, there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the properties or assets of a Person.

Transactions with Affiliates

The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any properties or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”), unless:

(1) the Affiliate Transaction is on terms that are not less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and

(2) the Company delivers to the applicable trustee:

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration to or from an Affiliate in excess of $10 million, a resolution of the Board of Directors of the Company set forth in an officers’ certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this covenant and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration to or from an Affiliate in excess of $20 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph:

(1) any employment agreement or arrangement, equity award, equity option or cash or equity settled equity appreciation agreement or plan, employee benefit plan, officer or director indemnification agreement, severance agreement, consulting agreement or other compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business or which is customary in the Oil and Gas Business, and payments, awards, grants or issuances of securities pursuant thereto;

(2) transactions between or among any of the Company and its Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or indirectly, an Equity Interest in, or otherwise controls, such Person or has nominated or appointed a person to the Board of Directors of that Person;

57

(4) customary compensation, indemnification and other benefits made available to officers, directors, employees or consultants of the Company or a Restricted Subsidiary of the Company, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

(5) issuances of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of capital contributions from, Affiliates of the Company and any dividend or distribution payable in Equity Interests (other than Disqualified Stock) of the Company;

(6) any Permitted Investments or Restricted Payments that are permitted by the provisions of the applicable indenture described above under the caption “—Restricted Payments”;

(7) transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that one director of such other Person is also a director of the Company or such Restricted Subsidiary, as applicable;provided that such director abstains from voting as a director of the Company or such Restricted Subsidiary, as applicable, on any matter involving such other Person;

(8) the existence of, and the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of, any written agreement to which the Company or any of its Restricted Subsidiaries is a party on the date of the applicable indenture, as these agreements may be amended, modified, supplemented or replaced from time to time;provided, however, that any amendment, modification, supplement or replacement entered into after the date of the applicable indenture will be permitted to the extent that its terms are not materially more disadvantageous, taken as a whole, to the Holders of the notes than the terms of the agreements in effect on the date of the applicable indenture (as conclusively evidenced by a Board Resolution);

(9) any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the applicable trustee an opinion from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (1) of the preceding paragraph;

(10) (a) guarantees by the Company or any of its Restricted Subsidiaries of performance of obligations of the Company’s Unrestricted Subsidiaries in the ordinary course of business or which are customary in the Oil and Gas Business and (b) pledges by the Company or any Restricted Subsidiary of the Company of Equity Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of the Company’s Unrestricted Subsidiaries;

(11) any Affiliate Transaction with a Person in its capacity as a holder of Indebtedness or Capital Stock of the Company or any Restricted Subsidiary of the Company if such Person is treated no more favorably than the other holders of Indebtedness or Capital Stock of the Company or such Restricted Subsidiary;

(12) transactions with joint venture partners, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in each case in the ordinary course of business or which are customary in the Oil and Gas Business and otherwise in compliance with the terms of the applicable indenture similar to those contained in similar contracts entered into by the Company or any Restricted Subsidiary and unrelated third parties, or if neither the Company nor any Restricted Subsidiary has entered into a similar contract with an unrelated third party, which are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially less favorable to the Company and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated third party, in the good faith determination of the Company’s Board of Directors or any executive officer of the Company involved in or otherwise familiar with such transaction; and

(13) dividends and distributions to the Company and its Restricted Subsidiaries by any Unrestricted Subsidiary.

58

Designation of Restricted and Unrestricted Subsidiaries

Currently all of the Subsidiaries of the Company are Restricted Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary of the Company (other than any Subsidiary owning Collateral) to be an Unrestricted Subsidiary if that designation would not cause a Default and other requirements for such designation prescribed in the definition of “Unrestricted Subsidiary” are satisfied. If a Restricted Subsidiary of the Company is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary properly designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of the covenant described above under the caption “—Restricted Payments” or represent Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary of the Company to be a Restricted Subsidiary,provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under the covenant described above under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock,” calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period, and (2) no Default (other than a Reporting Default) or Event of Default would be in existence following such designation.

Additional Subsidiary Guarantees

The indentures require any Material Domestic Subsidiary that is not already a Guarantor to become a Guarantor. In addition, if any Restricted Subsidiary of the Company that is not already a Guarantor guarantees any other Indebtedness of the Company or any Guarantor in excess of the De Minimis Guaranteed Amount, then that Subsidiary will become a Guarantor. Any such Subsidiary will become a Guarantor by executing a supplemental indenture and delivering it to the applicable trustee within 60 days of the date on which it became a Material Domestic Subsidiary or within 15 days of the date on which it guaranteed such Indebtedness, as the case may be.

Each Subsidiary Guarantee shall also be released in accordance with the provisions of the applicable indenture described under “—Subsidiary Guarantees” above.

Business Activities

The Company will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole.

Payments for Consent

Neither the Company nor any of its Restricted Subsidiaries will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fees or otherwise, to any Holder (or Beneficial Owner) of any notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the applicable indenture, the notes, the Security Documents or the Intercreditor Agreement unless such consideration is offered to be paid or is paid to all Holders (or Beneficial Owners) of the notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

Reports

Whether or not required by the Commission, so long as any notes are outstanding, the Company will file with the Commission for public availability within the time periods specified in the Commission’s rules and

59

regulations (taking into account any extension of time, deemed filing date or safe harbor contemplated or provided for by Rule 12b-25, Rule 13a-11(c), and Rule 15d-11(c) under the Securities Exchange Act of 1934, as amended, or General Instruction I.A.3(b) of Form S-3 under the Securities Act of 1933, as amended, and successor provisions) (unless the Commission will not accept such a filing, in which case the Company will furnish to the applicable trustee and, upon its prior request, to any Holder of notes, within the time periods specified in the Commission’s rules and regulations):

(1) all quarterly and annual financial information with respect to the Company and its Subsidiaries that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s certified independent accountants; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports.

In addition, the Company and the Guarantors will agree in the indentures that, for so long as any notes remain outstanding and are “restricted securities” within the meaning of Rule 144(a)(3), if at any time they are not required to file the reports required by the preceding paragraphs with the Commission, they will furnish to the Holders of the notes and to securities analysts and prospective investors in the notes, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. The Company will be deemed to have provided such information to the Holders, securities analysts and prospective Holders if it has filed reports containing such information with the Commission via the EDGAR filing system and such reports are publicly available.

If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and, to the extent material, in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Company’s Unrestricted Subsidiaries.

Information Regarding Collateral

The Security Documents provide that none of the parties will change its legal name, type of organization, jurisdiction of organization, organizational identification number or location without first giving at least 15 days’ prior written notice to the collateral agents and taking all action required by the collateral agents (including filings under the Uniform Commercial Code or otherwise) in order for the collateral agents to continue at all times following such change to have a valid, legal and perfected security interest in all of the Collateral with the priority required by the Security Documents.

Further Assurances

The indentures and the Security Documents provide that the Company and the Domestic Subsidiaries, at their own expense, will do or cause to be done all acts and things that may be required, or that the collateral agents from time to time may reasonably request, to assure and confirm that the collateral agents hold, for the benefit of the Holders, duly created and enforceable and perfected Liens upon the Collateral (including any property or assets that are acquired or otherwise become Collateral), in each case, as contemplated by, and with the Lien priority required under, the indentures, the Security Documents and the Intercreditor Agreement.

Upon the reasonable request of the collateral agents at any time and from time to time, the Company and the Domestic Subsidiaries, at their own expense, will promptly execute, acknowledge and deliver such security documents, instruments, certificates, notices and other documents, and take such other actions as may be

60

reasonably required, or that the collateral agents may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the indentures, the Security Documents and the Intercreditor Agreement.

After-Acquired Collateral

Upon the acquisition by the Company or any Domestic Subsidiary of any assets and properties that form part of the Collateral, the Company or such Domestic Subsidiary shall execute and deliver, to the extent required by the indentures and the Security Documents, any information, documentation, financing statements or other certificates as may be necessary to vest in the collateral agents a perfected security interest, in such after-acquired assets or property and to have such after-acquired assets or property added to the Collateral, and thereupon all provisions of the indentures, the Security Documents and the Intercreditor Agreement relating to the Collateral shall be deemed to relate to such after-acquired assets or property to the same extent and with the same force and effect.

Events of Default and Remedies

Each of the following is an “Event of Default” with respect to the notes of each tranche:

(1) default for 30 days in the payment when due of interest on the notes;

(2) default in payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on the notes;

(3) failure by the Company to comply with the provisions described under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets” or to consummate a purchase or redemption of notes when required pursuant to the provisions described under the caption “—Repurchase at the Option of Holders”;

(4) failure by the Company for 60 days after notice from the applicable trustee or the Holders of at least 25% in principal amount of the notes then outstanding to comply with the provisions described under “—Certain Covenants—Reports”;

(5) failure by the Company or any Guarantor for 60 days after notice from the applicable trustee or the Holders of at least 25% in principal amount of the notes of such tranche then outstanding to comply with any of the other agreements in the applicable indenture, the Security Documents or the Intercreditor Agreement (including the provisions described under the caption “—Repurchase at the Option of Holders” to the extent not described in clause (3) above);

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or is created after the date of the applicable indenture, if that default:

(a) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (a “Payment Default”); or

(b) results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $25 million or more;provided, however, that if any such default is cured or waived or any such acceleration rescinded, in each case within 20 days after the occurrence of such default or declaration of such acceleration, or such Indebtedness is repaid and the notes have not been accelerated, such Event of Default shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

61

(7) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $25 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 consecutive days;

(8) (a) any Subsidiary Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or (b) any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee, except, in each case, by reason of the release of such Subsidiary Guarantee in accordance with the applicable indenture;

(9) certain events of bankruptcy, insolvency or reorganization described in the indentures with respect to the Company or any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary or any group of the Company’s Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary of the Company; and

(10) (a) the applicable Security Documents shall for any reason cease to create a valid and perfected first-priority Lien (with respect to the first priority notes) or second-priority Lien (with respect to the second priority notes) on any material portion of the Collateral (in each case, other than in accordance with the terms of the applicable indenture or the terms of the applicable Security Documents), or (b) the Company or any Subsidiary asserts in writing that any Lien created under the Security Documents is invalid or unenforceable.

In the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization described in the indentures with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary of the Company, all outstanding notes will become due and payable immediately without further action or notice. If any other Event of Default occurs with respect to a tranche of notes and is continuing, the applicable trustee or the Holders of at least 25% in principal amount of the then outstanding notes of that tranche may declare all such notes to be due and payable immediately.

Holders of the notes may not enforce the applicable indenture, the notes or the Security Documents except, subject to the Intercreditor Agreement, as provided in those documents. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding notes of either tranche may direct the applicable trustee in its exercise of any trust or power with respect to such notes. The applicable trustee may withhold notice of any continuing Default or Event of Default from Holders of the notes of the affected tranche if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal of, or interest or premium, if any, on, such notes.

Subject to the provisions of the applicable indenture relating to the duties of the applicable trustee in case an Event of Default occurs and is continuing thereunder, the applicable trustee will be under no obligation to exercise any of the rights or powers under the applicable indenture at the request or direction of any Holders unless such Holders have offered to the applicable trustee satisfactory 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 applicable indenture unless:

(a) such Holder has previously given the applicable trustee notice of a continuing Event of Default;

(b) Holders of at least 25% in aggregate principal amount of the notes then outstanding under such indenture requested the applicable trustee to pursue the remedy;

(c) such Holders have offered the applicable trustee reasonable security or indemnity against any loss, liability or expense;

62

(d) the applicable trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity; and

(e) Holders of a majority in aggregate principal amount of the notes then outstanding under such indenture have not given the applicable trustee a direction that is inconsistent with such request within such 60-day period.

The Holders of a majority in principal amount of the then outstanding notes under such indenture by notice to the applicable trustee may on behalf of the Holders of all of the notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except with respect to nonpayment of principal, interest or premium, if any, that have become due solely because of the acceleration) have been cured or waived.

The Holders of a majority in principal amount of the notes of either tranche then outstanding by notice to the applicable trustee may on behalf of the Holders of all such notes waive (including, without limitation, in connection with a purchase of, or tender offer or exchange offer for, notes) any existing Default or Event of Default and its consequences under the applicable indenture except a continuing Default or Event of Default in the payment of principal of, or interest or premium, if any, on such notes or in respect of a covenant that cannot be amended without the consent of each Holder.

The Company will deliver to the applicable trustee annually a certificate regarding compliance with the applicable indenture, the Security Documents and the Intercreditor Agreement. Upon any officer of the Company becoming aware of any Default or Event of Default, the Company will deliver to the applicable trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, partner, employee, incorporator, manager or stockholder or other owner of Capital Stock of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or any Guarantor under the notes, the indentures, the Subsidiary Guarantees or the Security Documents, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Modification and Waiver

Subject to certain exceptions, each indenture, the notes of either tranche, each registration rights agreement, the Security Documents and the Intercreditor Agreement may be amended or supplemented with the consent of the Holders of a majority in principal amount of the notes of such tranche then outstanding under the applicable indenture (including without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes) and, subject to certain exceptions, any past default or compliance with any provisions thereof may be waived with the consent of the Holders of a majority in principal amount of the notes then outstanding under the applicable indenture (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes). However, no amendment, supplement or waiver may, without the consent of each Holder of an outstanding note affected thereby:

• reduce the principal amount of notes whose Holders must consent to an amendment, supplement or waiver;

• reduce the rate of or change the time for payment of interest on any note;

• reduce the principal of, any premium on, or change the stated maturity of, any note;

• reduce any premium payable on the redemption or repurchase of any note or change the time at which any note may or must be redeemed or repurchased;

63

• make any note payable in currency other than as stated in the notes;

• impair the rights of any Holder to receive payment on or with respect to such Holder’s notes or to institute suit for the enforcement of any payment on or with respect to such Holder’s notes;

• make any change in the amendment, supplement or waiver provisions that require each Holder’s consent;

• waive a continuing Default or Event of Default regarding any payment on the notes;

• release any Guarantor of its obligations under a Subsidiary Guarantee, except in accordance with the terms of the applicable indenture;

• make any change to or modify the ranking of the notes issued under the applicable indenture (or the Liens securing such notes or the Guarantees of such notes) that would adversely affect the holders of the applicable tranche of notes;

• make any change in the provisions in the Intercreditor Agreement, the applicable indenture or the applicable Security Documents dealing with the application of proceeds of Collateral that would adversely affect the holders of the applicable tranche of notes; or

• release all or substantially all of the Collateral from the Lien of the Security Documents, except in accordance with the terms of the applicable indenture.

Each indenture, the notes of each tranche, the Security Documents and Intercreditor Agreement may be amended or supplemented or any provision of such indenture, notes, Security Documents and the Intercreditor Agreement may be waived without the consent of any Holders of such notes in the following circumstances:

• to cure any ambiguity, omission, defect or inconsistency;

• to provide for the assumption of our obligations under such indenture, notes, Security Documents and the Intercreditor Agreement by a successor upon any merger or consolidation or sale, lease, conveyance, transfer or other disposition of all or substantially all of our properties or assets, in each case as permitted under such indenture;

• to provide for the assumption of the obligations of a Guarantor under such indenture, the Security Documents or the Intercreditor Agreement by a successor upon any merger or consolidation or sale, lease, conveyance, transfer or other disposition of all or substantially all of the properties or assets of such Guarantor, in each case as permitted under such indenture;

• to provide for uncertificated notes in addition to or in place of certificated notes;

• to provide any security for, any guarantees of or any additional obligors on the notes;

• to comply with any requirement to effect or maintain the qualification of such indenture under the Trust Indenture Act of 1939;

• to add covenants that would benefit the Holders or to surrender any rights we have under such indenture, notes, Security Documents and the Intercreditor Agreement;

• to add events of default with respect to such notes;

• to evidence the release of any Guarantor from its Subsidiary Guarantee or from the Security Documents to which it is a party in accordance with such indenture;

• to make, complete or confirm any grant of collateral permitted or required by such indenture or any of the Security Documents; and

• to make any change that does not adversely affect any of such outstanding notes;provided, that any change made solely to conform the provisions of such indenture, the notes, the Security Documents or the Intercreditor Agreement to this “Description of the Notes” will not be deemed to adversely affect any outstanding notes.

64

Defeasance

When we use the term defeasance, we mean discharge from some or all of our obligations under either indenture.

If we effect a “legal defeasance,” Holders of the notes will not be entitled to the benefits of the applicable indenture, the Security Documents or the Intercreditor Agreement except for (i) the rights of Holders of outstanding notes to receive payments in respect of the principal of, or interest or premium, if any, on such notes when such payments are due, (ii) obligations to register the transfer or exchange of notes, replace stolen, lost or mutilated notes, maintain paying agencies and hold moneys for payment in trust, (iii) the rights, powers, trusts, duties and immunities of the applicable trustee, and our obligations and the obligations of each Guarantor in connection therewith and (iv) the legal defeasance and covenant defeasance obligations of the applicable indenture.

If we effect a “covenant defeasance,” we and the Guarantors will no longer have any obligation to comply with the restrictive covenants relating to the notes, and the related Events of Default will no longer apply.

In order to exercise either defeasance option, we or a Guarantor must, among other things, irrevocably deposit in trust (the “defeasance trust”) with the applicable trustee money or government securities for the payment of principal, premium, if any, and interest on the notes to redemption or Stated Maturity, as the case may be, and must comply with certain other conditions, including delivery to the applicable trustee of an opinion of counsel (subject to customary exceptions and exclusions) to the effect that the holders of the notes 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.

Satisfaction and Discharge

Either indenture will be discharged and will cease to be of further effect as to all notes issued thereunder (except as to surviving rights of registration of transfer or exchange of the notes and as otherwise specified in such indenture), when:

(1) either:

(a) all such notes that have been authenticated, except lost, stolen or destroyed notes that have been replaced or paid and notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the applicable trustee for cancellation; or

(b) all such notes that have not been delivered to the applicable trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the applicable trustee as trust funds in trust solely for the benefit of the Holders, cash in United States dollars, non-callable government securities, or a combination of cash in United States dollars and non-callable government securities, in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the notes not delivered to the applicable trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(2) no Default or Event of Default under such indenture has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit or the grant of Liens securing such borrowing);

(3) such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than such indenture) to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound;

65

(4) the Company or any Guarantor has paid or caused to be paid all sums payable by it under the applicable indenture; and

(5) the Company has delivered irrevocable instructions to the applicable trustee to apply the deposited money toward the payment of the notes at maturity or on the redemption date, as the case may be.

In addition, the Company must deliver to the applicable trustee (a) an officers’ certificate, stating that all conditions precedent set forth in clauses (1) through (5) above have been satisfied and (b) an opinion of counsel, stating that all conditions precedent set forth in clauses (3) and (5) above have been satisfied.

Governing Law

New York law governs the indentures, the notes, the Subsidiary Guarantees, the Security Documents and the Intercreditor Agreement.

Trustee

Wells Fargo Bank, National Association acts as trustee under the first priority indenture and collateral agent for both tranches of the notes, and Wilmington Trust, National Association acts trustee under the second priority indenture.

If an Event of Default occurs under the first priority indenture or the second priority indenture and is continuing, the applicable trustee is required to use the degree of care and skill of a prudent person in the conduct of that person’s own affairs. Each trustee is obligated to exercise any of its powers under the applicable indenture at the request of any of the Holders only after those Holders have offered the applicable trustee satisfactory indemnity or security against any loss, liability or expense.

Each indenture contains limitations on the right of the applicable trustee, if it becomes our creditor or a creditor of any Guarantor, to obtain payment of claims or to realize on certain property received for any such claim, as security or otherwise. Each trustee is permitted to engage in other transactions with the Company or any Guarantor; however, if it acquires any conflicting interest (as defined in the Trust Indenture Act) after a Default has occurred and is continuing, it must eliminate that conflict within 90 days, apply to the Commission for permission to continue as trustee or resign.

Book-Entry, Delivery and Form

The new notes of each tranche initially will be represented by one or more global notes in registered form without interest coupons (collectively, the “Global Notes”).

The Global Notes will be deposited upon issuance with the applicable trustee as custodian for The Depository Trust Company (“DTC”) and registered in the name of DTC’s nominee, Cede & Co., in each case for credit to an account of a direct or indirect participant in DTC as described below.

Beneficial interests in the Global Notes may be held through the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) (as indirect participants in DTC).

Except as set forth below, the Global Notes may be transferred, in whole but not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in registered, certificated form (“Certificated Notes”) except in the limited circumstances described below. See “—Exchange of Global Notes for Certificated Notes.” In addition, transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear and Clearstream), which may change from time to time.

Depository Procedures

The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. We take no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

DTC has advised us that DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the “Participants”) and to facilitate the clearance and settlement of transactions in those securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the “Indirect Participants”). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants.

DTC has also advised us that, pursuant to procedures established by it:

(1) upon deposit of the Global Notes, DTC will credit the accounts of Participants designated by the exchange agents with portions of the principal amount of the Global Notes; and

(2) ownership of these interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interests in the Global Notes).

Investors in the Global Notes who are Participants may hold their interests therein directly through DTC.

Investors in the Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants. Euroclear and Clearstream may hold interests in the Global Notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositories, which are Euroclear Bank S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

The laws of some jurisdictions may require that certain Persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such Persons will be limited to that extent. Because DTC can act only on behalf of Participants, which in turn act on behalf of Indirect Participants, the ability of a Person having beneficial interests in a Global Note to pledge such interests to Persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

Except as described below, owners of an interest in the Global Notes will not have notes registered in their names, will not receive physical delivery of Certificated Notes and will not be considered the registered owners or “Holders” thereof under the indentures for any purpose.

Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered Holder under the indentures. Under the terms of the indentures, the Company, the Guarantors and the applicable trustee and their respective agents will treat the Persons in whose names the notes, including the Global Notes, are registered as the owners

67

of the notes for the purpose of receiving payments and for all other purposes. Consequently, neither the Company, the Guarantors, the trustees nor any agent of the Company, any Guarantor or the trustees has or will have any responsibility or liability for:

(1) any aspect of DTC’s records or any Participant’s or Indirect Participant’s records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC’s records or any Participant’s or Indirect Participant’s records relating to the beneficial ownership interests in the Global Notes; or

(2) any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants.

DTC has advised us that its current practice, at the due date of any payment in respect of securities such as the notes, is to credit the accounts of the relevant Participants with the payment on the payment date unless

DTC has reason to believe it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the notes as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustees or the Company. Neither the Company, the Guarantors nor the trustees will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the notes, and the Company, the Guarantors and the trustees may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between Participants will be effected in accordance with DTC’s procedures and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

Cross-market transfers between the Participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

DTC has advised us that it will take any action permitted to be taken by a Holder of notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default, DTC reserves the right to exchange the Global Notes for Certificated Notes, and to distribute such notes to its Participants.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. None of the Company, the Guarantors, the trustees or any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

68

Exchange of Global Notes for Certificated Notes

A Global Note is exchangeable for Certificated Notes in minimum denominations of $2,000 and in integral multiples of $1,000 in excess of $2,000, if:

(1) DTC (a) notifies the Company that it is unwilling or unable to continue as depositary for the Global Notes or (b) has ceased to be a clearing agency registered under the Exchange Act and, in either case, the Company fails to appoint a successor depositary within 90 days;

(2) the Company, at its option but subject to DTC’s requirements, notifies the applicable trustee in writing that it elects to cause the issuance of the Certificated Notes; or

(3) there has occurred and is continuing an Event of Default and DTC notifies the applicable trustee of its decision to exchange such Global Note for Certificated Notes.

In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Same Day Settlement and Payment

The Company will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by DTC or its nominee. If a Holder has given wire instructions to the Company, the Company will make all payments of principal, interest and premium, if any, with respect to Certificated Notes by wire transfer of immediately available funds to the accounts specified by the Holders of the Certificated Notes. All other payments on the notes will be made at the office or agency of the paying agent and registrar indicated under “—Methods of Receiving Payments on the Notes,” unless the Company elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders. The notes represented by the Global Notes are eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. The Company expects that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

If you wish to exchange new notes for your old notes of the relevant tranche in the applicable exchange offer, you will be required to make representations to us as described in “Exchange Offers—Purpose and Effect of the Exchange Offers” and “—Procedures for Tendering—Your Representations to Us” in this prospectus and in the letter of transmittal.

The following discussion is a summary of material U.S. federal income tax considerations relevant to the exchange of old notes for new notes, but does not purport to be a complete analysis of all potential tax effects. The discussion is based upon the Internal Revenue Code of 1986, as amended, or the Code, Treasury Regulations, Internal Revenue Service rulings and pronouncements and judicial decisions now in effect, all of which may be subject to change at any time by legislative, judicial or administrative action. These changes may be applied retroactively in a manner that could adversely affect a holder of new notes. We cannot assure you that the Internal Revenue Service will not challenge one or more of the tax considerations described in this discussion, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. federal tax consequences described herein. Some holders, including financial institutions, insurance companies, regulated investment companies, tax-exempt organizations, dealers in securities or currencies, persons whose functional currency is not the U.S. dollar, or persons who hold the notes as part of a hedge, conversion transaction, straddle or other risk reduction transaction may be subject to special rules not discussed below.

We recommend that each holder consult its own tax advisor as to the particular tax consequences of exchanging such holder’s old notes for new notes of the relevant tranche, including the applicability and effect of any foreign, state, local or other tax laws or estate or gift tax considerations.

We believe that the exchange of old notes for new notes of the relevant tranche will not be an exchange or otherwise a taxable event to a holder for United States federal income tax purposes. Accordingly, a holder will not recognize gain or loss upon receipt of a new note in exchange for an old note of the relevant tranche in the applicable exchange, and the holder’s tax basis and holding period in the new note will be the same as its tax basis and holding period in the corresponding old note immediately before the applicable exchange.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Our Articles of Incorporation provide that no officer or director of Endeavour will be personally liable to Endeavour or its stockholders for damages for breach of fiduciary duty as a director or officer, other than (1) for acts or omissions that involve intentional misconduct, fraud or knowing violations of law or (2) the unlawful payment of a distribution. In addition, our Articles of Incorporation and bylaws provide that Endeavour will indemnify its officers and directors and advance related costs and expenses incurred by our officers and directors to the fullest extent permitted by Nevada law. In addition, Endeavour may also enter into agreements with any officer or director and may obtain insurance indemnifying officers and directors against certain liabilities incurred by them.

Nevada Revised Statutes (“NRS”) Section 78.138 provides that a director or officer will not be individually liable unless it is proven that (i) the director’s or officer’s acts or omissions constituted a breach of his or her fiduciary duties, and (ii) such breach involved intentional misconduct, fraud or a knowing violation of the law.

Under NRS Section 78.7502(1), a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (except an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding if such person: (i) is not liable for a breach of fiduciary duties that involved intentional misconduct, fraud or a knowing violation of law; or (ii) acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

NRS Section 78.7502(2) further provides that a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including amounts paid in settlement and attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of the action or suit if such person: (i) is not liable for a breach of fiduciary duties that involved intentional misconduct, fraud or a knowing violation of law; or (ii) acted in good faith and in a manner that he or she reasonably believed to be in or not opposed to the best interests of the corporation. Indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

NRS Section 78.751 permits a Nevada corporation to indemnify its officers and directors against expenses incurred by them in defending a civil or criminal action, suit or proceeding as they are incurred and in advance of final disposition thereof, upon receipt of an undertaking by or on behalf of the officer or director to repay the amount if it is ultimately determined by a court of competent jurisdiction that such officer or director is not entitled to be indemnified by the corporation. NRS 78.751 further permits the corporation to grant its directors and officers additional rights of indemnification under its articles of incorporation or bylaws or otherwise. NRS

78.752 provides that a Nevada corporation may purchase and maintain insurance or make other financial arrangements on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, for any liability asserted against him and liability and expenses incurred by him in his capacity as a director, officer, employee or agent, or arising out of his status as such, whether or not the corporation has the authority to indemnify him against such liability and expenses.

Item 22. Undertakings.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrants, we have been advised that, in the opinion of the Securities and Exchange Commission, such indemnification is against public policy and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by any registrant of expenses incurred or paid by a director, officer or controlling person of a 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, such 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.

Each registrant hereby undertakes:

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to:

(a) include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(b) reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement; notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end

II-3

of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(c) to include any material information with respect to the plan of distribution not previously disclosed in this registration statement, or any material change to such information in this registration statement.

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment 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.

To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if such registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

That, for the purpose of determining liability of such registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, in a primary offering of securities of such registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(a) any preliminary prospectus or prospectus of the undersigned registrants relating to the offering required to be filed pursuant to Rule 424;

(b) any free writing prospectus relating to the offering prepared by or on behalf of such registrant or used or referred to by the undersigned registrants;

(c) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrants or their securities provided by or on behalf of such registrant; and

(d) any other communication that is an offer in the offering made by such registrant to the purchaser.

That, for purposes of determining any liability under the Securities Act of 1933, each filing of a registrant annual report pursuant to Section 13(a) or Section 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.

To deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished

II-4

pursuant to, and meeting the requirements of, Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

To respond to requests for information that are incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of Form S-4, 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 the registration statement through the date of responding to the request.

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 the registration statement when it became effective.

II-5
