Offer to Exchange

up to

$1,050,000,000 of 5.875% Senior Notes due 2026

that have been registered under the Securities Act of 1933

for any and all outstanding

$1,050,000,000 of 5.875% Senior Notes due 2026

that have not been registered under the Securities Act of 1933

The exchange offer and withdrawal rights will expire at 5:00 p.m., New York City time, on December 17, 2018 unless extended.

We are offering to exchange up to $1,050,000,000 aggregate principal amount of our outstanding 5.875% Senior Notes due 2026, or the “outstanding notes,” for new notes with substantially identical terms that have been registered under the Securities Act of 1933, as amended, or the Securities Act, and are freely transferable, which we refer to herein as the “exchange notes” and, together with the outstanding notes, the “notes”. We issued the outstanding notes on August 21, 2018 and October 4, 2018 in transactions not requiring registration under the Securities Act. We are offering you exchange notes in exchange for outstanding notes in order to satisfy our registration obligations from those previous transactions. The exchange notes will represent the same debt as the outstanding notes, and we will issue the exchange notes under the same indenture as the outstanding notes. The exchange notes offered hereby, together with any outstanding notes that remain outstanding after the completion of the exchange offer, will be treated as a single class under the indenture governing them.

Please read “Risk Factors” on page 9 of this prospectus for a discussion of factors you should consider before participating in the exchange offer.

We will exchange for an equal principal amount of exchange notes all outstanding notes that you validly tender and do not validly withdraw before the exchange offer expires. You may withdraw tenders of outstanding notes at any time prior to the expiration of the exchange offer. The exchange procedure is more fully described in “The Exchange Offer—Procedures for Tendering.” If you fail to tender your outstanding notes, you will continue to hold unregistered notes that you will not be able to transfer freely.

The terms of the exchange notes are substantially identical to the outstanding notes, except that the transfer restrictions, registration rights and provisions for additional interest applicable to the outstanding notes do not apply to the exchange notes.

Please read “Description of the Exchange Notes” for more details on the terms of the exchange notes. We will not receive any cash proceeds from the issuance of the exchange notes in the exchange offer.

Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such exchange notes. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received in exchange for outstanding notes where such outstanding notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period of 180 days after the consummation of the exchange offer, we will make this Prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is November 16, 2018.

RISK FACTORS

Before deciding to participate in the exchange offer, you should consider carefully the risks and uncertainties described below and in Item 1A—“Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2017 and our quarterly reports on Form 10-Q for the quarters ended March 31, 2018, June 30, 2018 and September 30, 2018, as updated by annual, quarterly and other reports and documents we file with the SEC after the date of this prospectus, together with all of the other information included or incorporated by reference in this prospectus. If any of the described risks actually were to occur, our business, financial condition, results of operations and cash flows could be materially adversely affected.

The risks described below are not the only ones facing the Company. Additional risks not presently known to us or that we currently deem immaterial individually or in the aggregate may also impair our business operations.

This prospectus and documents incorporated by reference herein also contain forward-looking statements that involve risks and uncertainties, some of which are described in the documents incorporated by reference in this prospectus. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including the risks and uncertainties faced by us described below or incorporated by reference in this prospectus. See “Cautionary Statement Regarding Forward-Looking Statements.”

Risks Related to the Exchange Offer

If you fail to exchange outstanding notes, existing transfer restrictions will remain in effect and the market value of outstanding notes may be adversely affected because they may be more difficult to sell.

If you fail to exchange outstanding notes for exchange notes under the exchange offer, then you will continue to be subject to the existing transfer restrictions on the outstanding notes. In general, the outstanding notes may not be offered or sold unless they are sold in transactions that are registered or exempt from registration under the Securities Act and applicable state securities laws. Except in connection with this exchange offer or as required by the registration rights agreements, we do not intend to register resales of the outstanding notes.

The tender of outstanding notes under the exchange offer will reduce the principal amount of the currently outstanding notes. Due to the corresponding reduction in liquidity, this may have an adverse effect upon, and increase the volatility of, the market price of any currently outstanding notes that you continue to hold following completion of the exchange offer.

Risks Related to the Exchange Notes

We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under applicable debt instruments, which may not be successful.

Our ability to make scheduled payments on or to refinance our indebtedness obligations, including our revolving credit facility and the notes, depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and certain financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.

If our cash flows and capital resources are insufficient to fund debt service obligations, we may be forced to reduce or delay investments and capital expenditures, sell assets, seek additional capital or restructure or refinance indebtedness. Our ability to restructure or refinance indebtedness will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict business

9

operations. The terms of existing or future debt instruments may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness. In the absence of sufficient cash flows and capital resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet debt service and other obligations. Our revolving credit facility currently restricts our ability to dispose of assets and our use of the proceeds from such disposition. We may not be able to consummate those dispositions, and the proceeds of any such disposition may not be adequate to meet any debt service obligations then due. These alternative measures may not be successful and may not permit us to meet scheduled debt service obligations.

As of October 31, 2018, the borrowing base under our revolving credit facility was $850.0 million with an elected borrowing commitment of $500.0 million. In the future, we may not be able to access adequate funding under our revolving credit facility as a result of a decrease in the borrowing base due to the issuance of new indebtedness, the outcome of a subsequent borrowing base redetermination or an unwillingness or inability on the part of lending counterparties to meet their funding obligations and the inability of other lenders to provide additional funding to cover the defaulting lender’s portion. Declines in commodity prices could result in a determination to lower the borrowing base in the future and, in such a case, we could be required to repay any indebtedness in excess of the redetermined borrowing base. As a result, we may be unable to implement our drilling and development plan, make acquisitions or otherwise carry out our business plans, which would have a material adverse effect on our financial condition and results of operations and impair our ability to service our indebtedness.

Our leverage and debt service obligations may adversely affect our financial condition, results of operations, business prospects and our ability to make payments on the exchange notes.

As of October 31, 2018, we and our wholly-owned subsidiaries had approximately $1.075 billion of outstanding indebtedness (excluding letters of credit), including $25.0 million in borrowings outstanding under our revolving credit facility, and we had approximately $472.0 million of borrowing capacity under our revolving credit facility. Our level of indebtedness could affect our operations in several ways, including the following:

10

The notes and the guarantees are unsecured obligations and are effectively subordinated to all of our existing and future secured indebtedness and structurally subordinated to liabilities of our non-guarantor subsidiaries.

The notes and the guarantees are general unsecured senior obligations ranking effectively junior to all of our existing and future secured indebtedness (including all borrowings under our revolving credit facility) to the extent of the value of the collateral securing such indebtedness. If we, or any of our guarantors, are declared bankrupt, become insolvent or are liquidated or reorganized, the holders of our secured indebtedness or the secured indebtedness of such guarantor will be entitled to be paid in full from the proceeds of the assets, if any, securing such indebtedness before any payment may be made with respect to the notes or the affected guarantees. Holders of the notes will participate ratably in any remaining proceeds with all holders of our unsecured indebtedness, including unsecured indebtedness incurred after the notes are issued that does not rank junior to the notes, including trade payables and all of our other general indebtedness, based on the respective amounts owed to each holder or creditor. In any of the foregoing events, there may not be sufficient funds to pay amounts due on the notes. As a result, holders of the notes would likely receive less, ratably, than holders of secured indebtedness.

The notes will also be structurally subordinated to any indebtedness and other liabilities of our subsidiaries that do not guarantee the notes. San Mateo and its subsidiaries are not guaranteeing the notes, and San Mateo held 12% of our consolidated assets as of September 30, 2018 and generated approximately 17% of our operating income for the nine months ended September 30, 2018. The indenture governing the exchange notes will permit us to form or acquire additional subsidiaries that are not guarantors of the notes in certain circumstances.

Holders of the notes will have no claim as a creditor against any of our non-guarantor subsidiaries. See “Description of the Exchange Notes—Brief Description of the Notes and Subsidiary Guarantees—The Subsidiary Guarantees.”

We and the guarantors may incur substantial additional indebtedness. This could increase the risks associated with the exchange notes.

Subject to the restrictions in the indenture governing the notes and in other instruments governing our other outstanding indebtedness (including our revolving credit facility), we and our subsidiaries may incur substantial additional indebtedness (including secured indebtedness) in the future. Although the indenture governing the notes and our revolving credit facility contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to waiver and a number of significant qualifications and exceptions, and indebtedness incurred in compliance with these restrictions could be substantial.

If we or a guarantor incurs any additional indebtedness that ranks equally with the notes (or with the guarantees thereof), including additional unsecured indebtedness or trade payables, the holders of that indebtedness will be entitled to share ratably with holders of the notes in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of us or a guarantor. This may have the effect of reducing the amount of proceeds paid to holders of the notes in connection with such a distribution. Any increase in our level of indebtedness will have several important effects on our future operations, including, without limitation:

11

We cannot assure you that we will be able to maintain or improve our leverage position.

An element of our business strategy involves maintaining a disciplined approach to financial management. However, we are also seeking to acquire, exploit and develop additional oil and natural gas reserves, which may require the incurrence of additional indebtedness. Although we will seek to maintain or improve our leverage position, our ability to maintain or reduce our level of indebtedness depends on a variety of factors, including future performance and our future debt financing needs. General economic conditions, oil and natural gas prices and financial, business and other factors will also affect our ability to maintain or improve our leverage position. Many of these factors are beyond our control.

The indenture governing the notes has restrictive covenants that, among other things, could limit our financial flexibility, our ability to engage in activities that may be in our long-term best interests and our ability and the ability of our restricted subsidiaries to:

See “Description of the Exchange Notes—Certain Covenants.” Our failure to comply with these covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all of our indebtedness. We would not have sufficient working capital to satisfy our debt obligations in the event of an acceleration of all or a significant portion of our outstanding indebtedness.

The borrowing base under our revolving credit facility is subject to periodic redetermination.

The borrowing base under the revolving credit facility is determined semi-annually as of May 1 and November 1 by the lenders based primarily on the estimated value of our proved oil and natural gas reserves at December 31 and June 30 of each year, respectively. Both we and the lenders may request an unscheduled redetermination of the borrowing base once each between scheduled redetermination dates. In addition, our lenders have the flexibility to reduce our borrowing base due to factors beyond our control. As of October 31, 2018, our borrowing base was $850.0 million and will remain at $850.0 million until the next redetermination. We could be required to repay a portion of our bank debt to the extent that after a redetermination our outstanding borrowings at such time exceed the redetermined borrowing base. We may not have sufficient funds to make such repayments, which could result in a default under the terms of the facility and an acceleration of the loans thereunder requiring us to negotiate renewals, arrange new financing or sell significant assets, all of which could have a material adverse effect on our business and financial results.

If we are unable to comply with the restrictions and covenants in the agreements governing the notes and our other indebtedness, there could be a default under the terms of these agreements, which could result in an acceleration of payment of funds that we have borrowed and would affect our ability to make principal and interest payments on the notes.

Any default under the agreements governing our indebtedness that is not cured or waived by the required lenders or holders of the notes, and the remedies sought by the holders of any such indebtedness, could make us unable to pay principal, premium, if any, and interest, or special interest, if any, on the exchange notes and substantially decrease the market value of the exchange notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and

12

interest, or special interest, if any, on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the agreements governing our indebtedness (including covenants in our revolving credit facility and the indenture governing the exchange notes), we could be in default under the terms of the agreements governing such indebtedness. In the event of such default:

If our operating performance declines, we may in the future need to obtain waivers under our revolving credit facility to avoid being in default. If we breach our covenants under our revolving credit facility and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under our revolving credit facility, the lenders could exercise their rights, as described above, and we could be forced into bankruptcy or liquidation.

We may not be able to fund a change of control offer.

If we experience certain kinds of changes of control events, we may be required to offer to repurchase all outstanding notes at 101% of their principal amount plus accrued and unpaid interest, if any. We may not be able to repurchase the notes upon a change of control event because we may not have sufficient financial resources to purchase all of the notes that are tendered following a change of control event. Our failure to repurchase the notes upon a change of control event could cause a default under the indenture governing the notes and could lead to a cross default under our revolving credit facility. Additionally, using cash to fund the potential consequences of a change of control event may impair our ability to obtain additional financing in the future, which could negatively impact our ability to conduct our business operations. See “Description of the Exchange Notes—Repurchase at the Option of Holders—Change of Control.”

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

Federal bankruptcy and state fraudulent transfer laws permit a court to avoid all or a portion of the obligations of a guarantor pursuant to its guarantee of the notes, or to subordinate any guarantor’s obligations under such guarantee to claims of its other creditors, reducing or eliminating the noteholders’ ability to recover under such guarantee. Although laws differ among these jurisdictions, in general, under applicable fraudulent transfer or conveyance laws, a guarantee could be voided as a fraudulent transfer or conveyance if (i) the guarantee was incurred with the intent of hindering, delaying or defrauding creditors; or (ii) the guarantor received less than reasonably equivalent value or fair consideration in return for incurring the guarantee and either:

A court would likely find that a guarantor did not receive reasonably equivalent value or fair consideration for its guarantee if the guarantor did not substantially benefit directly or indirectly from the issuance of the notes. If a court were to void a guarantee, you would no longer have a claim against the guarantor. Sufficient funds to

13

repay the outstanding notes may not be available from other sources, including the remaining guarantors, if any. In addition, the court might direct you to repay any amounts that you already received from the guarantor. The measures of insolvency for purposes of fraudulent transfer laws vary depending upon the governing law of the applicable jurisdiction. Generally, a guarantor would be considered insolvent if:

Each guarantee contains a provision intended to limit the guarantor’s liability under the guarantee to the maximum amount that the guarantor could incur without causing the incurrence of obligations under its guarantee to be deemed a fraudulent transfer. This provision may not be effective to protect the guarantees from being voided under fraudulent transfer law.

An active trading market for the notes does not exist and may not develop.

The exchange notes will be new securities for which there is currently no trading market. The notes will not be listed on any securities exchange. There can be no assurance that a trading market for the notes will ever develop or will be maintained. Further, there can be no assurance as to the liquidity of any market that may develop for the notes, your ability to sell your notes or the price at which you will be able to sell your notes. The initial purchasers have advised us that they intend to make a market in the notes, but there is no obligation for them to do so. Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the exchange notes. We cannot assure you that the market, if any, for the exchange notes will be free from similar disruptions. Any such disruption may adversely affect the holders of notes. Future trading prices of the notes will depend on many factors, including prevailing interest rates, our financial condition and results of operations, the then current ratings assigned to the notes and the market for similar securities. Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including the:

If an active market does not develop or is not maintained, the market price and liquidity of the notes may be adversely affected.

Many of the covenants contained in the indenture will be terminated if the notes are rated investment grade by S&P and Moody’s and no default has occurred and is continuing.

Many of the covenants in the indenture governing the notes will be terminated if the notes are rated investment grade by S&P and Moody’s, provided at such time no default or event of default has occurred and is continuing. These covenants include restrictions on our ability to pay dividends, to incur debt and to enter into certain transactions. There can be no assurance that the notes will ever be rated investment grade.

14

However, termination of these covenants would allow us to engage in certain transactions that would not have been permitted while these covenants were in force. The covenant termination will continue even if the notes are subsequently downgraded below investment grade. See “Description of the Exchange Notes—Covenant Termination.”

We face risks related to rating agency downgrades.

We expect one or more rating agencies to rate the notes offered hereby. If such rating agencies either assign the notes a rating lower than the rating expected by investors, or reduce the rating in the future, the market price of the notes may be adversely affected, raising capital may become more difficult and borrowing costs under our revolving credit facility and other future borrowings may increase.

15

USE OF PROCEEDS

The exchange offer is intended to satisfy our obligations under the registration rights agreements. We will not receive any cash proceeds from the issuance of the exchange notes in the exchange offer. In consideration for issuing the exchange notes as contemplated by this prospectus, we will receive outstanding notes in a like principal amount. The form and terms of the exchange notes are identical in all respects to the form and terms of the outstanding notes, except the exchange notes do not include certain transfer restrictions, registration rights or provisions for additional interest. Outstanding notes surrendered in exchange for the exchange notes will be retired and canceled and will not be reissued. Accordingly, the issuance of the exchange notes will not result in any change in our outstanding indebtedness.

16

THE EXCHANGE OFFER

We sold the outstanding notes on August 21, 2018 and October 4, 2018 pursuant to purchase agreements, dated as of August 7, 2018 and October 1, 2018, respectively, by and among us, our subsidiary guarantors and the initial purchasers named therein. The outstanding notes were subsequently offered by the initial purchasers to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons pursuant to Regulation S under the Securities Act.

Purpose of the Exchange Offer

We sold outstanding notes in transactions that were exempt from or not subject to registration requirements under the Securities Act. Accordingly, the outstanding notes are subject to transfer restrictions. In general, you may not offer or sell the outstanding notes unless either they are no longer subject to certain restrictions on transfer or the offer or sale is exempt from or not subject to registration under the Securities Act and applicable state securities laws.

In connection with the sale of the outstanding notes, we entered into registration rights agreements with the initial purchasers of the outstanding notes. We are making the exchange offer to fulfill our contractual obligations under those agreements. Copies of the registration rights agreements have been filed as exhibits to the registration statement of which this prospectus is a part. The exchange offer will be open for at least 20 business days.

Pursuant to the exchange offer, we will issue the exchange notes in exchange for outstanding notes. The terms of the exchange notes are identical in all material respects to those of the outstanding notes, except that the exchange notes (1) will not be subject to certain restrictions on transfer applicable to the outstanding notes and (2) will not have registration rights or provide for any increase in the interest rate related to the obligation to register. See “Description of the Exchange Notes” for more information on the terms of the exchange notes.

We are not making the exchange offer to, and will not accept tenders for exchange from, holders of outstanding notes in any jurisdiction in which an exchange offer or the acceptance thereof would not be in compliance with the securities or blue sky laws of such jurisdiction. Unless the context requires otherwise, the term “holder” means any person whose outstanding notes are held of record by The Depository Trust Company, or DTC, who desires to deliver such outstanding notes by book-entry transfer at DTC.

We make no recommendation to the holders of outstanding notes as to whether to tender or refrain from tendering all or any portion of their outstanding notes pursuant to the exchange offer. In addition, no one has been authorized to make any such recommendation. Holders of outstanding notes must make their own decision whether to tender pursuant to the exchange offer and, if so, the aggregate amount of outstanding notes to tender after reading this prospectus and the letter of transmittal and consulting with their advisers, if any, based on their own financial position and requirements.

Each broker-dealer that receives exchange notes for its own account in exchange for outstanding notes, where such securities were acquired by such broker-dealer as a result of market making activities or other trading activities, must acknowledge that it will deliver a prospectus that meets the requirements of the Securities Act in connection with any resale of the exchange notes. See “Plan of Distribution.”

Resales of Exchange Notes

Based on interpretations by the staff of the SEC, as described in no-action letters issued to third parties, we believe that exchange notes issued in the exchange offer in exchange for outstanding notes may be offered for

17

resale, resold or otherwise transferred by holders of the outstanding notes without compliance with the registration and prospectus delivery provisions of the Securities Act, if:

However, the SEC has not considered the exchange offer described in this prospectus in the context of a no-action letter. We cannot assure you that the staff of the SEC would make a similar determination with respect to the exchange offer as in the other circumstances. Each holder who wishes to exchange outstanding notes for exchange notes will be required to represent that it meets the above three requirements.

Any holder who is an affiliate of ours or who intends to participate in the exchange offer for the purpose of distributing exchange notes or any broker-dealer who purchased outstanding notes directly from us to resell pursuant to Rule 144A or any other available exemption under the Securities Act:

Unless an exemption from registration is otherwise available, any securityholder intending to distribute exchange notes should be covered by an effective registration statement under the Securities Act. The registration statement should contain the selling securityholder’s information required by Item 507 or 508, as applicable, of Regulation S-K under the Securities Act.

In addition, to comply with state securities laws, the exchange notes may not be offered or sold in any state unless they have been registered or qualified for sale in such state or an exemption from registration or qualification, with which there has been compliance, is available. The offer and sale of the exchange notes to “qualified institutional buyers,” as defined under Rule 144A of the Securities Act, is generally exempt from registration or qualification under the state securities laws. We currently do not intend to register or qualify the sale of exchange notes in any state where an exemption from registration or qualification is required and not available.

Terms of the Exchange Offer

Upon the terms and conditions described in this prospectus and in the accompanying letter of transmittal, which together constitute the exchange offer, we will accept for exchange outstanding notes which are properly tendered at or before the expiration time and not withdrawn as permitted below. Outstanding notes tendered in the exchange offer must be in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

The exchange offer is not conditioned upon any minimum aggregate principal amount of outstanding notes being tendered in the exchange offer.

As of the date of this prospectus, $1,050,000,000 in aggregate principal amount of outstanding notes are outstanding. This prospectus is being sent to DTC, the sole registered holder of the outstanding notes. There will be no fixed record date for determining registered holders of outstanding notes entitled to participate in the exchange offer.

18

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

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

If you tender outstanding notes in the 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 outstanding notes. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the exchange offer. Please read “—Fees and Expenses” for more details regarding fees and expenses incurred in connection with the exchange offer.

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

Expiration, Extension and Amendment

The expiration time of the exchange offer is 5:00 p.m., New York City time, on December 17, 2018. However, we may, in our sole discretion, at any time or various times, extend the period of time for which the exchange offer is open and set a later expiration date. The term “expiration time” as used herein means the latest time and date to which we extend the exchange offer. If we decide to extend the exchange offer period, we will then delay acceptance of any outstanding notes by giving written notice of an extension to the holders of outstanding notes as described below. During any extension period, all outstanding notes previously tendered will remain subject to the exchange offer and may be accepted for exchange by us. Any outstanding notes not accepted for exchange will be returned to the tendering holder after the expiration or termination of the exchange offer.

Our obligation to accept outstanding notes for exchange in the exchange offer is subject to the conditions described below under “—Conditions to the Exchange Offer.” We may decide to waive any of the conditions in our discretion. Furthermore, we reserve the right to amend or terminate the exchange offer, and to not accept for exchange any outstanding notes not previously accepted for exchange, if the conditions of the exchange offer specified below under the same headings are not fulfilled. We will give written notice of any extension, amendment, non-acceptance or termination to the holders of the outstanding notes as promptly as practicable. If we amend the 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 holders of the outstanding notes. If the change is made less than five business days before the expiration of the exchange offer, we will extend the offer so that the holders have at least five business days to tender or withdraw. In the event of any increase or decrease in the consideration we are offering for the outstanding notes or in the percentage of outstanding notes being sought by us, we will extend the exchange offer to remain open for at least 10 business days after the date we provide notice of such increase or decrease to the registered holders of outstanding notes. We will notify you of any extension by means of a press release or other public announcement no later than 9:00 a.m., New York City time on the first business day after the previously scheduled expiration time.

Procedures for Tendering

To participate in the exchange offer, you must properly tender your outstanding notes to the exchange agent as described below. We will only issue exchange notes in exchange for outstanding notes that you timely and

19

properly tender. You should follow carefully the instructions on how to tender your outstanding notes. It is your responsibility to properly tender your outstanding notes. We have the right to waive any defects. However, we are not required to waive defects, and neither we nor the exchange agent is required to notify you of any defects in your tender.

If you have any questions or need help in exchanging your outstanding notes, please call the exchange agent whose address and phone number are listed under the heading “—Exchange Agent” and in the letter of transmittal included as Annex A to this prospectus.

All of the outstanding notes were issued in book-entry form, and all of the outstanding notes are currently represented by global certificates registered in the name of Cede & Co., the nominee of DTC. We have confirmed with DTC that the outstanding notes may be tendered using ATOP. The exchange agent will establish an account with DTC for purposes of the exchange offer 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 outstanding 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 outstanding notes and that the participant agrees to be bound by the terms of the letter of transmittal.

By using the ATOP procedures to exchange outstanding 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 outstanding notes.

If you beneficially own outstanding notes that are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender those notes, you should contact the registered holder as soon as possible and instruct the registered holder to tender on your behalf.

Determinations Under the Exchange Offer. We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered outstanding notes and withdrawal of tendered outstanding notes. Our determination will be final and binding. We reserve the absolute right to reject any outstanding notes not properly tendered or any outstanding notes our acceptance of which might, 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 outstanding notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, all defects or irregularities in connection with tenders of outstanding 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 outstanding notes, neither we, the exchange agent nor any other person will incur any liability for failure to give such notification. Tenders of outstanding notes will not be deemed made until such defects or irregularities have been cured or waived. Any outstanding 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 promptly following the expiration time.

When We Will Issue Exchange Notes. In all cases, we will issue exchange notes for outstanding notes that we have accepted for exchange under the exchange offer only after the exchange agent receives, prior to 5:00 p.m., New York City time, on the expiration date,

Such notes will be issued promptly following the expiration or termination of the offer.

Return of Outstanding Notes Not Accepted or Exchanged. If we do not accept any tendered outstanding notes for exchange or if outstanding notes are submitted for a greater principal amount than the holder desires to

20

exchange, the unaccepted or non-exchanged outstanding notes will be returned without expense to their tendering holder. Such non-exchanged outstanding notes will be credited to an account maintained with DTC. These actions will occur promptly after the expiration or termination of the 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:

Each broker-dealer that receives exchange notes for its own account in exchange for outstanding notes, where such securities were acquired by such broker-dealer as a result of market making activities or other trading activities, must acknowledge that it will deliver a prospectus that meets the requirements of the Securities Act in connection with any resale of the exchange notes. See “Plan of Distribution.”

Withdrawal of Tenders

Except as otherwise provided in this prospectus, you may withdraw your tender at any time prior to 5:00 p.m., New York City time, on the expiration date of the exchange offer. For a withdrawal to be effective you must comply with the appropriate ATOP procedures. Any notice of withdrawal must specify the name and number of the account at DTC to be credited with withdrawn outstanding notes and otherwise comply with the ATOP procedures.

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

Any outstanding notes that have been tendered for exchange but that are not exchanged for any reason will be credited to an account maintained with DTC for the outstanding notes. This return or crediting will take place promptly after withdrawal, rejection of tender, expiration or termination of the exchange offer. You may retender properly withdrawn outstanding notes by following the procedures described under “—Procedures for Tendering” above at any time on or prior to the expiration time.

Conditions to the Exchange Offer

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

We will not be obligated to accept for exchange the outstanding notes of any holder that has not made to us the representations described under “—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 exchange notes under the Securities Act.

21

Additionally, we will not accept for exchange any outstanding notes tendered, and will not issue exchange notes in exchange for any such outstanding notes, if at such time any stop order has been threatened or is in effect with respect to the exchange offer registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939.

We expressly reserve the right to amend or terminate the exchange offer, and to reject for exchange any outstanding notes not previously accepted for exchange, upon the occurrence of any of the conditions to the exchange offer specified above. We will promptly give written notice of any extension, amendment, non-acceptance or termination to the holders of the outstanding notes.

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 prior to the expiration of the exchange offer in our sole discretion. 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 exchange offer.

Exchange Agent

Wells Fargo Bank, National Association has been appointed as the exchange agent for the exchange offer. All executed letters of transmittal and any other required documents should be directed to the exchange agent at the address or facsimile number set forth below. Questions and requests for assistance and requests for additional copies of this prospectus or of the letter of transmittal should be directed to the exchange agent addressed as follows:

Delivery of the letter of transmittal to an address other than as set forth above or transmission of the letter of transmittal via a facsimile transmission to a number other than as set forth above will not constitute a valid delivery of the letter of transmittal. Delivery of documents to The Depository Trust Company does not constitute delivery to the exchange agent.

Fees and Expenses

We will bear the expenses of soliciting tenders. The principal solicitation is being made by e-mail; however, we may make additional solicitation by mail, telephone 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 offer and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offer. 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 offer. They include:

22

Transfer Taxes

We will pay all transfer taxes, if any, applicable to the exchange of outstanding notes under the exchange offer. Each 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 outstanding notes under the exchange offer.

Consequences of Failure to Exchange

If you do not exchange your outstanding notes for exchange notes under the exchange offer, the outstanding notes you hold will continue to be subject to the existing restrictions on transfer. In general, you may not offer or sell the outstanding notes except under an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not intend to register outstanding notes under the Securities Act unless the registration rights agreements require us to do so.

Accounting Treatment

We will record the exchange notes at the same carrying value as the outstanding notes, as reflected in our accounting records on the date of the exchange. Accordingly, we will not recognize any gain or loss for accounting purposes. The expenses of the exchange offer will be amortized over the term of the exchange notes.

Other

Participation in the exchange offer is voluntary, and you should consider carefully 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 outstanding notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plans to acquire any outstanding notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered outstanding notes.

23

DESCRIPTION OF THE EXCHANGE NOTES

The Company issued the outstanding notes and will issue the exchange notes (collectively, the “Notes”) under an indenture (the “Indenture”) dated August 21, 2018 by and among itself, the Guarantors and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The terms of the outstanding notes and the exchange notes will include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The following description is a summary of the material provisions of the Indenture. It does not restate this agreement in its entirety. The Company urges you to read the Indenture because it, and not this description, define your rights as Holders of the Notes. You may request copies of the Indenture at the Company’s address set forth under the headings “—Additional Information” and “Where You Can Find More Information.”

You can find the definitions of certain terms used in this description under the subheadings “—Certain Definitions” and “—Principal, Maturity and Interest.” In this description, the word “Company” refers only to Matador Resources Company and not to any of its subsidiaries.

The registered holder of a Note will be treated as the owner of it for all purposes. Only registered holders of Notes will have rights under the Indenture, and all references to “Holders” in this description are to registered holders of Notes.

If the exchange offer is consummated, Holders of outstanding notes who do not exchange their notes for exchange notes will vote together with the Holders of the exchange notes for all relevant purposes under the Indenture. In that regard, the Indenture requires that certain actions by the Holders under the Indenture (including acceleration after an Event of Default) must be taken, and certain rights must be exercised, by specified minimum percentages of the aggregate principal amount of all Notes issued under the 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 Indenture, any outstanding notes that remain outstanding after the exchange offer will be aggregated with the exchange notes, and the Holders of any outstanding notes and the exchange notes will vote together as a single series for all such purposes. Accordingly, all references in this “Description of the Exchange Notes” to specified percentages in aggregate principal amount of the outstanding notes mean, at any time after the exchange offer for the outstanding notes is consummated, such percentage in aggregate principal amount of such notes and the exchange notes then outstanding.

Brief Description of the Notes and Subsidiary Guarantees

The Notes

Like the outstanding notes, the exchange notes:

24

The Subsidiary Guarantees

Like the outstanding notes, the exchange notes will be jointly and severally guaranteed by each of the Company’s present Restricted Subsidiaries, and by any of its future Restricted Subsidiaries that guarantee Indebtedness of the Company or another Guarantor under a Credit Facility.

The Subsidiary Guarantees of the Notes:

All of the Company’s Subsidiaries (other than the Joint Venture Subsidiaries) are “Restricted Subsidiaries.” Under the circumstances described below under the subheading “—Certain Definitions—Unrestricted Subsidiary,” the Company is permitted to designate certain of its Subsidiaries as “Unrestricted Subsidiaries.” Unrestricted Subsidiaries are not subject to many of the restrictive covenants in the Indenture and do not guarantee the Notes.

Our Joint Venture Subsidiaries held 12% of our consolidated assets as of September 30, 2018 and generated approximately 17% of our operating income for the nine months ended September 30, 2018.

Principal, Maturity and Interest

The Company has issued $1,050,000,000 in aggregate principal amount of outstanding notes. The Company may issue Additional Notes (“Additional Notes”) from time to time after this offering in an unlimited amount, without the consent of the Holders but subject to the provisions of the Indenture described below under the caption “—Certain Covenants—Incurrence of Indebtedness.” The outstanding notes and any Additional Notes subsequently issued under the Indenture, together with the exchange notes, will be treated as a single class for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. Unless otherwise provided or the context otherwise requires, for all purposes of the Indenture and this “Description of the Exchange Notes,” references to the Notes include any Additional Notes and Exchange Notes actually issued. The Company will issue Notes in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof. The Notes will mature on September 15, 2026.

Interest on the Notes accrues at the rate of 5.875% per year and is payable semiannually in arrears on March 15 and September 15, commencing on March 15, 2019. The Company will make each interest payment to the Holders of record of the Notes on the immediately preceding March 1 and September 1.

Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Methods of Receiving Payments on the Notes

If a Holder of not less than $5.0 million aggregate principal amount of any Notes held in definitive form has given wire transfer instructions to the Company for an account in the U.S., the Company will make all principal, premium and interest payments on those Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent unless the Company elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders.

25

The Company will make all principal, premium and interest payments on each Note in global form registered in the name of The Depository Trust Company (“DTC”) or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the Holder of such Global Note (as defined below).

Paying Agent and Registrar for the Notes

The Trustee is acting as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Notes, and the Company or any of its Subsidiaries may act as Paying Agent or Registrar.

Transfer and Exchange

A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company is not required to transfer or exchange any Note selected for redemption. Also, the Company is not required to transfer or exchange any Note for a period of 15 days before a selection of Notes to be redeemed.

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

Subsidiary Guarantees

The Guarantors jointly and severally guarantee the Company’s obligations under the Notes on a senior unsecured basis. The obligations of each Guarantor under its Subsidiary Guarantee are limited in a manner intended to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance under applicable laws, although no assurance can be given that a court would give the Holders the benefit of such a provision. Please read “Risk Factors—Risks Related to the Exchange Notes—Federal and state statutes allow courts, under specific circumstances, to void guarantees and require noteholders to return payments received from guarantors.”

Except in a transaction resulting in the release of a Subsidiary Guarantee of a Guarantor, the Company will not permit a Guarantor to 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 that transaction, no Default or Event of Default shall have occurred and be continuing; and

(2) the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of that Guarantor under its Subsidiary Guarantee pursuant to a supplemental indenture satisfactory to the Trustee.

The Subsidiary Guarantee of a Guarantor will be released in accordance with the applicable provisions of the Indenture:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) other than to the Company or another Guarantor, if such transaction as of the time of such disposition does not violate the provisions of the Indenture described under the caption “—Repurchase at the Option of Holders—Asset Sales”;

(2) in connection with any sale or other disposition of the Capital Stock of a Guarantor (including by way of merger or consolidation) other than to the Company or another Guarantor, if such transaction at the time of such disposition does not violate the provisions of the Indenture described under the caption “—Repurchase at the Option of Holders—Asset Sales” and the Guarantor ceases to be a Restricted Subsidiary of the Company as a result of such transaction;

26

(3) if the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the provisions of the Indenture;

(4) if the Company effects a Legal Defeasance or Covenant Defeasance as described under “—Legal Defeasance and Covenant Defeasance” or if it satisfies and discharges the Indenture as described under “Satisfaction and Discharge”; or

(5) at such time as such Guarantor ceases to guarantee any other Indebtedness of the Company or any other Guarantor under a Credit Facility.

Optional Redemption

Prior to September 15, 2021, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes (including any Additional Notes) originally issued prior to the redemption date under the Indenture in an amount not greater than the Net Cash Proceeds of one or more Equity Offerings, at a redemption price of 105.875% of the principal amount thereof, 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); provided that

(1) at least 65% in aggregate principal amount of Notes (including any Additional Notes) originally issued under the Indenture remain outstanding immediately after the occurrence of such redemption (excluding Notes held by the Company and its Subsidiaries); and

(2) each such redemption must occur within 180 days of the date of the closing of the related Equity Offering.

In addition, at any time prior to September 15, 2021, the Company may redeem all or part of the Notes at a redemption price equal to the sum of:

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).

On or after September 15, 2021, the Company may redeem all or a part of the Notes at any time or from time to time at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, 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 September 15 of the years indicated below:

Except pursuant to the preceding paragraphs, or as described below in the last paragraph under “—Repurchase at the Option of Holders—Change of Control,” the Notes will not be redeemable at the Company’s option prior to maturity.

27

Selection and Notice

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption as follows:

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

(2) if the Notes are not so listed, on a pro rata basis (or, in the case of Notes in global form, the Notes represented thereby will be selected in accordance with DTC’s prescribed method).

Notes or portions of Notes the Trustee selects for redemption shall be in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof. Notices of redemption shall be given in the manner prescribed in the Indenture at least 15 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address, except that notices of redemption may be given more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notices of redemption may be subject to one or more conditions precedent specified in the notice of redemption, including completion of an Equity Offering or other corporate transaction. If a notice of redemption is subject to the satisfaction of one or more conditions precedent, the related notice shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied or waived (provided that in no event shall such redemption date be delayed to a date later than 60 days after the date on which such notice was sent), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the redemption date, or by the redemption date as so delayed. The Company shall provide written notice of the satisfaction or waiver of such conditions, the delay of such redemption date or the rescission of such notice of redemption to the Trustee prior to the close of business one Business Day prior to the redemption date, and the Trustee shall provide such notice to each Holder of Notes in the same manner in which the notice of redemption was given. Upon receipt of such notice of the delay of such redemption date or the rescission of such notice of redemption, such redemption date shall be automatically delayed or such notice of redemption shall be automatically rescinded, as applicable, and the redemption of the Notes shall be automatically delayed or rescinded and cancelled, as applicable, as provided in such notice.

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note shall state the portion of the principal amount thereof 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 Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption, subject to satisfaction of any conditions to the redemption. On and after the redemption date, interest will cease to accrue on Notes or portions of them called for redemption.

Mandatory Redemption; Offers to Purchase; Open Market Purchases

The Company is not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Company may be required to offer to purchase Notes as described under the captions “—Repurchase at the Option of Holders—Change of Control” and “—Asset Sales.” The Company may at any time and from time to time purchase Notes in the open market or otherwise.

Repurchase at the Option of Holders

Change of Control

If a Change of Control Triggering Event occurs, unless the Company has previously or concurrently exercised its right to redeem all of the Notes as described under “—Optional Redemption,” each Holder of Notes will have the right to require the Company to repurchase all or any part (in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof) of that Holder’s Notes pursuant to the offer described

28

below (the “Change of Control Offer”). In the Change of Control Offer, the Company will offer a payment (the “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of Notes to be repurchased plus accrued and unpaid interest thereon, if any, to the date of purchase (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 purchase).

No later than 30 days following any Change of Control Triggering Event, the Company will send a notice to each Holder (with a copy to the Trustee) describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the Change of Control Payment Date specified in such notice, which date will be no earlier than 30 days nor later than 60 days from the date such notice is mailed, pursuant to the procedures required by the Indenture 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 such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of the covenant described herein, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of the Company’s compliance with such securities laws or regulations.

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

(1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;

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

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

The Paying Agent will promptly mail to each Holder of Notes so tendered and not withdrawn the Change of Control Payment for such tendered Notes, with such payments to be made through the facilities of DTC for all Notes in global form, and the Trustee will promptly authenticate and send (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, by such Holder; provided that each such new Note will be in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

The Company will announce to the Holders of Notes the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The provisions described above that require the Company to make a Change of Control Offer following a Change of Control is applicable regardless of whether or not any other provisions of the Indenture are applicable. Except as described above with respect to a Change of Control, the Indenture does 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 Credit Agreement currently treats certain change of control events with respect to the Company as an event of default entitling the lenders to terminate all further lending commitments, to accelerate all loans then outstanding and to exercise other remedies. The occurrence of a Change of Control may result in a default under future Indebtedness of the Company and its Subsidiaries, and give the lenders thereunder the right to require the Company 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 future Indebtedness, even if the Change of Control Triggering Event 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 Triggering Event also may be limited by the Company’s then existing financial resources.

29

The Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer, (2) a notice of redemption for all outstanding Notes has been given, unless and until there is a default in payment of the applicable redemption price or (3) in connection with or in contemplation of any publicly announced Change of Control, the Company has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer.

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

The definition of Change of Control includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the assets of the Company and its 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 such Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Company and its Subsidiaries taken as a whole may be uncertain.

If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer or Alternate Offer and the Company, or any other Person making a Change of Control Offer or Alternate Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company will have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or Alternate Offer described above, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment or Alternate Offer price, as applicable, plus, to the extent not included in the Change of Control Payment or Alternate Offer price, as applicable, accrued and unpaid interest, if any, to the date of redemption (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 purchase).

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 the time of such Asset Sale at least equal to the Fair Market Value of the Equity Interests or other assets issued or sold or otherwise disposed of (which may be determined at the time of entering into any agreement with respect to such Asset Sale); and

(2) (A) at least 75% of the aggregate consideration therefor received by the Company or such Restricted Subsidiary, as the case may be, from such Asset Sale and all other Asset Sales since the 2023 Notes Issue Date, on a cumulative basis, is in the form of cash, Cash Equivalents or assets of the type referred to in clauses (2) or (3) of the next succeeding paragraph, or any combination of the foregoing (together, “Permitted Consideration”) or (B) the Fair Market Value of all forms of consideration other than Permitted Consideration since the Issue Date does not exceed in the aggregate 10% of the ACNTA of the Company (determined at the time of receipt of such consideration), with the Fair Market Value of each item

30

of consideration measured at the time received and without giving effect to subsequent changes in value. For purposes of this provision, each of the following shall be deemed to be cash:

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

(b) with respect to any Asset Sale of properties used or useful in the Oil and Gas Business by the Company or any of its Restricted Subsidiaries where the Company or such Restricted Subsidiary retains an interest in such property, the amount of the costs and expenses of the Company or such Restricted Subsidiary related to the exploration, development, completion or production of such properties and activities related thereto which the transferee (or an Affiliate thereof) agrees to pay;

(c) Indebtedness (other than contingent liabilities and liabilities that are by their terms subordinated to the notes or a Guarantee) of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale; provided that the Company and each other Restricted Subsidiary are released from any Guarantee of such Indebtedness in connection with such Asset Sale;

(d) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted within 180 days by the Company or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion);

(e) solely in the case of any Asset Sale of Midstream Assets, Permitted MLP Securities; and

(f) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale; provided that the aggregate fair market value of such Designated Non-cash Consideration, taken together with the fair market value at the time of receipt of all other Designated Non-cash Consideration received pursuant to this clause (f) less the amount of Net Proceeds previously realized in cash from prior Designated Non-cash Consideration is less than 5.0% of ACNTA at the time of the receipt of such Designated Non-cash Consideration (with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value).

Notwithstanding the foregoing, in the case of any Asset Sale pursuant to a condemnation, appropriation or similar taking, including by deed in lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of clauses (1) and (2) above.

Within the later of (x) one year after the date of receipt of any Net Proceeds from an Asset Sale and (y) six months after the date of an agreement entered into within such one-year period committing the Company or Restricted Subsidiary to make an acquisition or expenditure referred to in clauses (2) or (3) below, the Company or a Restricted Subsidiary may apply such Net Proceeds at its option, in any one or more of the following:

(1) to repay, prepay, redeem or repurchase any Indebtedness of the Company or any Restricted Subsidiary (other than Subordinated Indebtedness);

(2) to acquire all or substantially all of the assets of, or a majority of the Voting Stock of, a company principally engaged in the Oil and Gas Business that will, upon such acquisition, become a Restricted Subsidiary or acquire any minority interest in a Restricted Subsidiary; or

(3) to make capital expenditures or to acquire properties or assets, in each case that are used or useful in the Oil and Gas Business.

Pending the final application of any such Net Proceeds, the Company may invest such Net Proceeds in any manner not prohibited by the Indenture.

31

Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $50.0 million, the Company will make an offer (the “Asset Sale Offer”) to all Holders of Notes (with a copy to the Trustee) and, to the extent required by the terms thereof, all holders of other Indebtedness that is pari passu in right of payment with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price with respect to the Notes in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase (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 purchase), and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and the Company shall select such other pari passu Indebtedness to be purchased on a pro rata basis (or, in the case of Notes in global form, the Notes represented thereby will be selected in accordance with DTC’s prescribed method), on the basis of the aggregate principal amounts tendered in round denominations (which in the case of the Notes will be in a minimum principal amount of $2,000 or integral multiples of $1,000 in excess thereof). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall 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 such laws and regulations are applicable in connection with an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of the covenant described herein, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of the Company’s compliance with such securities laws or regulations.

Certain Covenants

Restricted Payments

(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 by the Company or any Restricted Subsidiary 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);

32

(4) make any Investment other than a Permitted Investment (all such payments and other actions set forth in clauses (1) through (3) above and this clause (4) being collectively referred to as “Restricted Payments”),

unless, at the time of and after giving effect to such Restricted Payment:

(1) no Default (except a Reporting Default) or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;

(2) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made 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

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12) or (13) of the next succeeding paragraph), 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 April 1, 2015 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

(b) 100% of the aggregate Net Cash Proceeds and 100% of the Fair Market Value of securities or other property other than cash (including Capital Stock of Persons engaged in the Oil and Gas Business or assets used in the Oil and Gas Business) received by the Company or a Restricted Subsidiary since the 2023 Notes Issue Date from the issue or sale of Equity Interests of the Company (other than Disqualified Stock), other than Equity Interests sold to a Subsidiary of the Company or to an employee stock ownership plan or to a trust established by the Company or any of its Subsidiaries for the benefit of their employees; plus

(c) the amount by which Indebtedness is reduced on the Company’s consolidated balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to the 2023 Notes Issue Date of any Indebtedness convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company (plus the amount of any accrued interest then outstanding on such Indebtedness to the extent the obligation to pay such interest is extinguished less the amount of any cash, or the Fair Market Value of any property (as determined in good faith by an officer of the Company), distributed by the Company upon such conversion or exchange), together with the net proceeds, if any, received by the Company or its Restricted Subsidiaries upon such conversion or exchange; plus

(d) an amount equal to the sum of (i) the net reduction in the Investments (other than Permitted Investments) made by the Company or any Restricted Subsidiary in any Person resulting from repurchases, repayments or redemptions of such Investments by such Person, proceeds realized on the sale of such Investments and proceeds representing the return of capital (excluding dividends and distributions to the extent included in Consolidated Net Income), in each case received by the Company or any Restricted Subsidiary since the 2023 Notes Issue Date, and (ii) to the extent such Person is an Unrestricted Subsidiary, the portion (proportionate to the Company’s equity interest in such Subsidiary) of the Fair Market Value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that to the extent the foregoing sum exceeds, in the case of any such Person or Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or any Restricted Subsidiary in such Person or Unrestricted Subsidiary since

33

the 2023 Notes Issue Date, such excess shall not be included in this clause (d) unless the amount represented by such excess has not been and will not be taken into account in one of the foregoing clauses (a)-(c).

The preceding provisions will not prohibit:

(1) the payment of any dividend or the consummation of any redemption within 60 days after the date of declaration or giving of redemption notice, as the case may be, thereof, if at said date of declaration or notice such payment would have complied with the provisions of the Indenture (and such payment shall be deemed to be paid on the date of payment for purposes of any calculation required by this covenant);

(2) any Restricted Payment made in exchange for, or out of the Net Cash Proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock), with any such payment being deemed to be “substantially concurrent” if made within 180 days of the sale of the Equity Interests in question; provided that the amount of any such Net Cash Proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition shall be excluded from clause (3)(b) of the preceding paragraph;

(3) the defeasance, redemption, repurchase, retirement or other acquisition of any Subordinated Indebtedness of the Company or any Guarantor with the Net Cash Proceeds from an incurrence of any Permitted Refinancing Indebtedness permitted to be incurred under the caption “—Incurrence of Indebtedness”;

(4) the payment of any dividend or other distribution by a Restricted Subsidiary of the Company to the holders of its common Equity Interests on a pro rata basis or on a basis more favorable to the Company or any Restricted Subsidiary;

(5) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any employees, former employees, directors or former directors of the Company or any of its Restricted Subsidiaries (or heirs, estates or other permitted transferees of such employees or directors) pursuant to any agreements (including employment agreements), management equity subscription agreements or stock option agreements or plans (or amendments thereto), approved by the Board of Directors, under which such individuals purchase or sell or are granted the right to purchase or sell shares of Capital Stock; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $15.0 million in any calendar year, with unused amounts in any calendar year being permitted to be carried over to succeeding calendar years subject to a maximum of $30.0 million in any calendar year; provided, further, however, that such amount in any calendar year may be increased by an amount not to exceed:

(a) the cash proceeds received by the Company or any of the Restricted Subsidiaries from the sale of Equity Interests (other than Disqualified Stock) of the Company or any direct or indirect parent of the Company (to the extent contributed to the Company) to members of management, directors, managers or consultants of the Company and the Restricted Subsidiaries or any direct or indirect parent of the Company that occurs after the Issue Date (provided that the amount of such cash proceeds utilized for any such repurchase, retirement, other acquisition or dividend will not increase the amount available for Restricted Payments under clause (3)(b) of the preceding paragraph), plus

(b) the cash proceeds of key man life insurance policies received by the Company or any direct or indirect parent of the Company (to the extent contributed to the Company) or the Restricted Subsidiaries after the Issue Date; provided that the Company may elect to apply all or any portion of the aggregate increase contemplated by clauses (a) and (b) above in any calendar year; and provided, further, that cancellation of Indebtedness owing to the Company or any Restricted Subsidiary from any present or former employees, directors, managers, officers or consultants of the Company, any Restricted Subsidiary or the direct or indirect parents of the Company in connection with a repurchase of Equity Interests of the Company or any of its direct or indirect parents will not be deemed to constitute a Restricted Payment for purposes of this covenant or any other provision of the Indenture;

34

(6) loans or advances to employees of the Company or employees or directors of any Subsidiary of the Company, in each case as permitted by Section 402 of the Sarbanes-Oxley Act of 2002, the proceeds of which are used to purchase Capital Stock of the Company, or to refinance loans or advances made pursuant to this clause (6), in an aggregate amount not in excess of $2.0 million at any one time outstanding;

(7) repurchases or other acquisitions for value of Capital Stock deemed to occur upon the exercise or exchange of stock options, warrants or other convertible securities if such Capital Stock represents a portion of the exercise or exchange price thereof or made in lieu of withholding taxes in connection with any such exercise or exchange;

(8) upon the occurrence of a Change of Control or an Asset Sale and within 60 days after the completion of the offer to repurchase the Notes under the covenants described under “—Repurchase at the Option of Holders—Change of Control” or “—Asset Sales” above (including the purchase of all Notes tendered and required to be purchased), any purchase, repurchase, redemption, defeasance, acquisition or other retirement for value of Subordinated Indebtedness required under the terms thereof as a result of such Change of Control or Asset Sale at a purchase or redemption price not to exceed 101% of the outstanding principal amount thereof, plus accrued and unpaid interest thereon, if any, provided that, in the notice to Holders relating to a Change of Control or Asset Sale hereunder, the Company shall describe this clause (8);

(9) the purchase by the Company of fractional shares arising out of stock dividends, splits or business combinations or conversion of convertible or exchangeable securities of debt or equity issued by the Company;

(13) other Restricted Payments not to exceed $75.0 million in the aggregate since the Issue Date.

The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities other than cash that are required to be valued by this covenant will be determined, in the case of amounts in excess of $20.0 million, by an officer of the Company and, in the case of amounts in excess of $50.0 million, by the Board of Directors of the Company whose resolution with respect thereto will be delivered to the Trustee.

For purposes of determining compliance with this covenant, if a Restricted Payment meets the criteria of more than one of the types of Restricted Payments described in clauses (1)-(13) above or pursuant to the first paragraph of this covenant, the Company, in its sole discretion, may order and classify, and subsequently reorder and reclassify, such Restricted Payment in any manner in compliance with this covenant.

Incurrence of Indebtedness

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 (including Acquired Debt); provided, however, that the

35

Company and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt), 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 would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the Net Cash Proceeds therefrom), as if the additional Indebtedness had been incurred at the beginning of such four-quarter period.

The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Indebtedness”):

(1) the incurrence by the Company and any Restricted Subsidiary of Indebtedness under one or more Credit Facilities; provided that the aggregate principal amount of all Indebtedness incurred under this clause (1) and outstanding at any time does not exceed an amount equal to the greatest of (a) $725.0 million, (b) the Borrowing Base and (c) 35.0% of ACNTA at the time of incurrence;

(2) the incurrence by the Company and its Restricted Subsidiaries of Existing Indebtedness (other than Indebtedness described under clauses (1), (3) or (6) of this paragraph);

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by (a) the Notes and related Subsidiary Guarantees issued on the date of the indenture and (b) any Notes and related Subsidiary Guarantees issued pursuant to a registration rights agreement in exchange for the Notes issued on the date of the indenture;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings, industrial revenue bonds, purchase money obligations or other Indebtedness or preferred stock, or synthetic lease obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, development, construction, installation or improvement of property (real or personal and including Capital Stock), plant or equipment used in the business of the Company or any of its Restricted Subsidiaries (in each case, whether through the direct purchase of such assets or the Equity Interests of any Person owning such assets), in an aggregate principal amount, taken together with Permitted Refinancing Indebtedness in respect thereof, that does not exceed the greater of $100.0 million and 5.0% of ACNTA at the time of incurrence;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the Net Cash Proceeds of which are used to refund, refinance, replace, defease or discharge Indebtedness (other than intercompany Indebtedness) that was permitted by the Indenture to be incurred under the first paragraph of this covenant or clauses (2), (3), (4), (12) or (15) or this clause (5) of this paragraph;

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

(a) (i) if the Company is the obligor on such Indebtedness and the obligee is not a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes, and (ii) if a Guarantor is the obligor of such Indebtedness and the obligee is neither the Company nor a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations of such Guarantor with respect to its Subsidiary Guarantee; and

(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 thereof and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary thereof, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause;

(7) in-kind obligations relating to net oil and natural gas balancing positions arising in the ordinary course of business;

36

(8) self-insurance obligations and any obligations in respect of completion bonds, performance bonds, bid bonds, plugging and abandonment bonds, appeal bonds, surety bonds, bankers acceptances, letters of credit, insurance obligations or bonds and other similar bonds and obligations incurred by the Company or any Restricted Subsidiary in the ordinary course of business and any Guarantees or letters of credit functioning as or supporting any of the foregoing bonds or obligations;

(9) any obligation (including deferred premiums) under Interest Rate Agreements, Currency Agreements and Commodity Agreements; provided, that such Interest Rate Agreements, Currency Agreements and Commodity Agreements are entered into for bona fide hedging purposes of the Company or its Restricted Subsidiaries (as determined in good faith by the Board of Directors or senior management of the Company);

(10) any obligation arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, Guarantee, adjustment of purchase price, holdback, contingency payment obligation based on the performance of the acquired or disposed asset or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, asset or Capital Stock;

(11) any obligation arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five Business Days of incurrence;

(12) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness;

(13) any Guarantee of Indebtedness of the Company or a Restricted Subsidiary to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated or pari passu with the Notes, the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed;

(14) Indebtedness incurred on behalf of, or representing guarantees of Indebtedness of, Persons other than the Company or any Restricted Subsidiaries in which the Company or a Restricted Subsidiary has an Investment; provided, however, that the aggregate principal amount of Indebtedness incurred under this clause (14), when aggregated with the principal amount of all other Indebtedness then outstanding and incurred pursuant to this clause (14), does not exceed the greater of $100.0 million and 5.0% of ACNTA at the time of incurrence; and

(15) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in addition to Indebtedness permitted by clauses (1) through (14) above or the first paragraph above in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (15), not to exceed the greater of (a) $100.0 million and (b) 5.0% of the Company’s ACNTA, determined as of the date of incurrence of such Indebtedness after giving effect to such incurrence and the application of the proceeds therefrom.

For purposes of determining compliance with this “Indebtedness” covenant:

(1) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (15) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company will be permitted to classify such item of Indebtedness (or any portion thereof) on the date of its incurrence and, subject to clause (2) below, may later reclassify such items of Indebtedness (or any portion thereof), in any manner that complies with this covenant, and only be required to include the amount and type of such Indebtedness in one of such clauses or may include the amount and type of such Indebtedness partially in one such clause and partially in one or more other such clauses;

(2) all Indebtedness outstanding on the Issue Date under the Credit Agreement after giving effect to the offering of the outstanding notes and the use of proceeds therefrom shall be deemed initially incurred on the

37

Issue Date under clause (1) of the second paragraph of this covenant and not the first paragraph or clause (2) of the second paragraph of this covenant;

(3) Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included;

(4) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP;

(5) Indebtedness of any Person existing at the time such Person becomes a Restricted Subsidiary shall be deemed to have been incurred by the Company and the Restricted Subsidiary at the time such Person becomes a Restricted Subsidiary; and

(6) the accrual of interest or dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred equity as Indebtedness due to a change in accounting principles, the payment of dividends on Disqualified Stock or preferred equity in the form of additional shares of the same class of Disqualified Stock or preferred equity will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred equity 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 shall be calculated based on the relevant currency exchange rate in effect on the date such 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 such 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 such 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. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company 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, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such 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 suffer to exist any Lien on any property or asset now owned or hereafter acquired, except Permitted Liens, to secure (a) any Indebtedness of the Company unless prior to, or contemporaneously therewith, the Notes are equally and ratably secured for so long as such other Indebtedness is so secured, or (b) any Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary Guarantee of such Guarantor is equally and ratably secured for so long as such other Indebtedness is so secured; provided, however, that if such Indebtedness is expressly subordinated to the Notes or a Subsidiary Guarantee, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Notes or such Subsidiary Guarantee, as the case may be, with the same relative priority as such Indebtedness has with respect to the Notes or such Subsidiary Guarantee.

38

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 to:

(a) pay dividends or make any other distributions on its Capital Stock to the Company or any of the Company’s Restricted Subsidiaries, or pay any Indebtedness owed to the Company or any of the Company’s Restricted Subsidiaries (it being understood that the priority of any preferred stock in receiving dividends, distributions or liquidating distributions prior to dividends, distributions or liquidating distributions being paid on Capital Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock);

(b) make loans or advances to the Company or any of the Company’s Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Company or any of its Restricted Subsidiaries to other Indebtedness incurred by the Company or any of its Restricted Subsidiaries shall not be deemed a restriction on the ability to make loans or advances); or

(c) transfer any of its properties or assets to the Company or any of the Company’s Restricted Subsidiaries.

However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements existing on the Issue Date, including the Credit Agreement as in effect on the Issue Date and the Indenture, the Notes and the Subsidiary Guarantees;

(2) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred;

(3) any agreement for the sale or other disposition of Capital Stock or assets of a Restricted Subsidiary that restricts distributions by such Restricted Subsidiary pending such sale or other disposition;

(4) any amendment, restatement, modification, supplement, extension, renewal, refunding, replacement or refinancing of Indebtedness referred to in clauses (1) or (2), provided that the encumbrances or restrictions contained in the agreements governing the foregoing are not materially more restrictive, taken as a whole, than those contained in the agreements governing such Indebtedness as determined in good faith by the Company;

(5) cash or other deposits, or net worth requirements or similar requirements, imposed by suppliers, or other deposits by parties under agreements entered into in the ordinary course of the Oil and Gas Business of the types described in the definition of Permitted Business Investments;

(6) any applicable law, rule, regulation, order, approval, license, permit or similar restriction;

(7) provisions limiting the disposition or distribution of assets or property or transfer of Capital Stock in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements, limited liability company organizational documents, and other similar agreements entered into in the ordinary course of business, consistent with past practice or with the approval of the Company’s Board of Directors or any of its officers, which limitation is applicable only to the assets, property or Capital Stock that are the subject of such agreements;

(8) any encumbrance or restriction contained in the terms of any Indebtedness or Capital Stock permitted to be incurred under the Indenture or any agreement pursuant to which such Indebtedness was

39

incurred if either (x) in the case of Indebtedness, the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (y) the Company determines that any such encumbrance or restriction either (i) will not materially affect the Company’s ability to make principal or interest payments on the Notes and such restrictions are not materially less favorable to Holders of Notes than is customary in comparable financings or (ii) are not materially more restrictive, taken as a whole, with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date or those contained in the Indenture or the Credit Agreement, in each case as determined in good faith by the Board of Directors or an officer of the Company;

(9) encumbrances or restrictions applicable only to a Restricted Subsidiary that is not a Domestic Subsidiary;

(10) any encumbrance or restriction with respect to an Unrestricted Subsidiary pursuant to or by reason of an agreement that the Unrestricted Subsidiary is a party to or entered into before the date on which such Unrestricted Subsidiary became a Restricted Subsidiary; provided that such agreement was not entered into in anticipation of the Unrestricted Subsidiary becoming a Restricted Subsidiary and any such encumbrance or restriction does not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property of such Unrestricted Subsidiary; and

(11) with respect to clause (c) of the preceding paragraph only, any of the following encumbrances or restrictions:

(a) purchase money obligations for property acquired in the ordinary course of business or otherwise permitted under the Indenture that impose restrictions on the property so acquired;

(b) Permitted Liens or Liens securing Indebtedness otherwise permitted to be incurred pursuant to the provisions of the covenant described above under the caption “—Liens” that limit the right of the Company or any of its Restricted Subsidiaries to dispose of the assets subject to such Lien;

(c) restrictions contained in asset sale agreements limiting the transfer of such assets pending the closing of such sale;

(d) restrictions on the subletting, assignment or transfer of any property or asset that is subject to a lease, license, sublicense or similar contract, or on the assignment or transfer of any such lease, license, sub-license or other contract;

(e) agreements governing Hedging Obligations entered into in the ordinary course of business; and

(f) customary restrictions on the disposition or distribution of assets or property in agreements entered into in the ordinary course of the Oil and Gas Business of the types described in the definition of Permitted Business Investments.

Merger, Consolidation or Sale of Assets

The Company may not: (1) consolidate or merge with or into another Person (whether or not the Company is the surviving corporation); or (2) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless:

(1) either:

(a) the Company is the surviving corporation; or

(b) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a Person existing under the laws of the United States, any state thereof or the District of Columbia;

40

(2) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Notes and the Indenture pursuant to a supplemental indenture reasonably satisfactory to the Trustee;

(3) immediately after such transaction no Default or Event of Default exists;

(4) either (a) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company) would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, be 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 above under the caption “—Certain Covenants—Incurrence of Indebtedness” or (b) immediately after giving effect to such transaction on a pro forma basis 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 Company is equal to or greater than the Fixed Charge Coverage Ratio of the Company immediately before such transaction; and

(5) the Company has delivered to the Trustee an officers’ certificate and an Opinion of Counsel, each stating that such consolidation, merger or disposition and such supplemental indenture (if any) comply with the Indenture and all conditions precedent therein relating to such transaction have been satisfied and an Opinion of Counsel stating that the Notes and the indenture constitute the valid and binding obligations of the Company (or, if applicable, the successor company).

The surviving or transferee Person in any of the above transactions (if not the Company) will succeed to, and be substituted for the Company under the Indenture and the Notes and the Company (if not the surviving Person) will be fully released from its obligations under the Indenture and the Notes, except in the case of a lease of all or substantially all of its assets.

For purposes of this covenant, the sale, assignment, transfer, lease, conveyance or other disposition 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.

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.

Clauses (3) and (4) of this “Merger, Consolidation, or Sale of Assets” covenant will not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among the Company and any of its Restricted Subsidiaries that are Guarantors.

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 property 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 (each, an “Affiliate Transaction”) involving aggregate consideration to or from the Company or a Restricted Subsidiary in excess of $10.0 million, unless:

(1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained at the time of such

41

transaction in arm’s-length dealings by the Company or such Restricted Subsidiary with a Person that is not an Affiliate or, if in the good faith judgment of the Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or such Restricted Subsidiary from a financial point of view; and

(2) (a) the Company delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration to or from the Company or a Restricted Subsidiary in excess of $20.0 million, an officers’ certificate certifying that such Affiliate Transaction complies with the requirements of clause (1) above, and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration to or from the Company or a Restricted Subsidiary in excess of $50.0 million, a majority of the Disinterested Members of the Board of Directors, if any, (or, if there is only one Disinterested Member, such Disinterested Member) have approved such Affiliate Transaction(s), as evidenced by a resolution delivered to the Trustee and certified by an officers’ certificate as having been adopted by the Board of Directors.

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

(1) any employment or severance agreement or other employee, consulting, service, termination or director compensation agreement, arrangement or plan, (or any amendment thereto with respect thereto), or indemnification agreements, entered into by the Company or any Restricted Subsidiary with officers and employees of the Company or any Restricted Subsidiary thereof and the payment of compensation to officers and employees of the Company or any Restricted Subsidiary thereof (including amounts paid pursuant to employee benefit plans, employee stock option or similar plans), so long as such agreement or payment is in the ordinary course of business or has been approved by a majority of the Disinterested Members of the Board of Directors (or, if there is only one Disinterested Member, such Disinterested Member);

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

(3) Restricted Payments that, in each case, are permitted by the provisions of the Indenture described above under the caption “—Restricted Payments” or Permitted Investments;

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

(5) loans or advances to employees, officers or directors in the ordinary course of business of the Company or any of its Restricted Subsidiaries, in each case only as permitted by Section 402 of the Sarbanes-Oxley Act of 2002, but in any event not to exceed $2.0 million in the aggregate outstanding at any one time;

(6) any transactions undertaken pursuant to any contracts in existence on the Issue Date (as in effect on the Issue Date) and any renewals, replacements or modifications of such contracts (pursuant to new transactions or otherwise) on terms no less favorable to the holders of the Notes than those in effect on the Issue Date;

(7) in the case of (i) contracts for (A) drilling or other oil-field services or supplies, (B) the sale, storage, gathering, processing, treating, transport or disposal of hydrocarbons or water or activities or services reasonably related thereto or (C) the lease or rental of office or storage space or (ii) other operation type or administrative services contracts, any such contracts that are entered into in the ordinary course of business (x) which are fair to the Company and its Restricted Subsidiaries, in the good faith determination of the Board of Directors of the Company or the senior management thereof or (y) which are on terms substantially similar to those contained in similar contracts entered into by the Company or any Restricted Subsidiary and third parties or, if neither the Company nor any Restricted Subsidiary has entered into a similar contract with a third party, that the terms are on the whole not materially less favorable than those

42

that would be reasonably expected to be available from third parties on an arm’s-length basis, as determined in good faith by the Company;

(8) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Subsidiary, an Equity Interest in, or controls, such Person;

(9) any sale or other issuance of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of a capital contribution from, an Affiliate (or a Person that becomes an Affiliate) of the Company;

(10) any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, deliver to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction meets the requirements of clause (1) of the first paragraph of this covenant;

(11) any transaction between the Company or any Restricted Subsidiary on the one hand and any Person deemed to be an Affiliate solely because a director of such Person is also a director of the Company or a Restricted Subsidiary, on the other hand; provided that such director abstains from voting as a director of the Company or the Restricted Subsidiary, as applicable, in connection with the approval of the transaction; and

(12) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of the business of the Company and its Restricted Subsidiaries and otherwise in compliance with the Indenture; provided that such transactions are on terms substantially similar to those obtained by the Company or any Restricted Subsidiary in similar transactions with third parties or, if neither the Company nor any Restricted Subsidiary has entered into a similar transaction with a third party, that are on the whole not materially less favorable than those that would be reasonably expected to be available from third parties on an arm’s-length basis, as determined in good faith by the Company.

Additional Subsidiary Guarantees

If any Restricted Subsidiary of the Company that is not already a Guarantor guarantees any Indebtedness of the Company or any Guarantor under a Credit Facility, then that Subsidiary will become a Guarantor by executing a supplemental indenture and delivering it and an officers’ certificate stating that the execution of the supplemental indenture is authorized by the indenture and the Notes to the Trustee within 30 days of the date on which it guaranteed such Indebtedness. Any such guarantee shall be subject to release as described under “—Subsidiary Guarantees.”

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.

Reports

Whether or not required by the SEC, so long as any Notes are outstanding, the Company will furnish to the Holders of Notes, within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms, including a section on “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 public accountants; and

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

43

If the Company has designated as an Unrestricted Subsidiary any of its Subsidiaries that is a Significant Subsidiary (or that, taken together with other Unrestricted Subsidiaries, would be a Significant Subsidiary), then the quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and 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 Unrestricted Subsidiaries of the Company.

The availability of the foregoing materials on the SEC’s website or on the Company’s website shall be deemed to satisfy the foregoing delivery obligations.

In the event that any direct or indirect parent company of the Company becomes a guarantor of the Notes, the Company may satisfy its obligations in this covenant with respect to financial information relating to the Company by furnishing financial information relating to such parent company; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such parent, on the one hand, and the information relating to the Company and its Subsidiaries on a standalone basis, on the other hand.

In addition, the Company will agree that, for so long as any Notes remain outstanding and are “restricted securities” under Rule 144 under the Securities Act, if at any time it is not required to file with the SEC the reports required by the preceding paragraphs, it will furnish to beneficial owners of Notes and to prospective investors, upon request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt thereof shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Company’s, any Guarantor’s or any other person’s compliance with any of the covenants under the Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on an officers’ certificate). The Trustee will not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s, any Guarantor’s or any other person’s compliance with any of the covenants described herein or to determine whether such reports, information or documents have been posted on any website or other online data system or filed with the SEC.

Covenant Termination

From and after the occurrence of an Investment Grade Rating Event, and upon the delivery by the Company to the Trustee of an officers’ certificate to the foregoing effect (the “Termination Date”), the Company and its Restricted Subsidiaries will no longer be subject to the provisions of the Indenture described in “—Repurchase at the Option of Holders—Asset Sales” or in “—Certain Covenants” above under the following headings:

(collectively, the “Eliminated Covenants”). As a result, after the date on which the Company and its Restricted Subsidiaries are no longer subject to the Eliminated Covenants, the Notes will be entitled to substantially reduced covenant protection.

44

After the foregoing covenants have been terminated, the Company may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the second sentence of the definition of “Unrestricted Subsidiary.”

The Trustee shall not have any obligation to monitor the ratings of the Notes or the occurrence or date of the Termination Date and may rely conclusively on the officers’ certificate referred to above. The Trustee shall not have any obligation to notify the Holders of the Notes of the occurrence or date of the Termination Date, but may provide a copy of such officers’ certificate to any Holder of Notes upon request.

Events of Default and Remedies

Each of the following is an Event of Default:

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

(2) default in payment when due of the principal of or premium, if any, on the Notes;

(3) failure by the Company to comply with its obligations to offer to purchase or purchase Notes under the provisions described under the captions “—Repurchase at the Option of the Holders—Change of Control” and “—Asset Sales” or its failure to comply with the provisions described under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets”;

(4) failure by the Company for 180 days after receipt of written notice from the Trustee or the Holders of 25% in principal amount of the Notes to comply with the provisions described under the caption “—Certain Covenants—Reports”;

(5) failure by the Company for 60 days after receipt of written notice from the Trustee or the Holders of 25% in principal amount of the Notes to comply with any of its other agreements in the Indenture;

(6) default under any mortgage, indenture or instrument under which there is issued or by which there is 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, if that default:

(a) is caused by a failure to pay when due any principal 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 $50.0 million or more (the “Cross-Acceleration Provision”); provided, however, that if any such Payment Default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such Payment Default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

(7) failure by the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (net of any amounts covered by insurance or a binding indemnity agreement), which judgments are not paid, discharged or stayed for a period of 60 days (the “Judgment Provision”);

(8) any Subsidiary Guarantee of a Guarantor shall be held in any judicial proceeding to be unenforceable or invalid or, except as permitted by the Indenture, shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee (the “Guarantee Default Provision”), in each case with respect to any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken together, would constitute a Significant Subsidiary; and

45

(9) certain events of bankruptcy or insolvency with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary (the “Bankruptcy Provision”).

In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Under certain circumstances, the Holders of a majority in principal amount of the then outstanding Notes may rescind an acceleration with respect to the Notes and its consequences.

Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture.

Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium or interest) if it determines that withholding notice is in their interest.

The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a Default or Event of Default in respect of a provision that under “—Amendment, Supplement and Waiver” below cannot be amended or waived without the consent of each Holder affected.

The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture. Upon becoming aware of any Default or Event of Default, the Company is required to deliver to the Trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator, member, partner, stockholder or other owner of the Capital Stock of the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Subsidiary Guarantees, the Registration Rights Agreements 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.

Legal Defeasance and Covenant Defeasance

The Company may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding Notes and the Indenture and all obligations of the Guarantors discharged with respect to their Subsidiary Guarantees (“Legal Defeasance”) except for:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due from the trust referred to below;

(2) the Company’s obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee, and the Company’s obligations in connection therewith; and

(4) the Legal Defeasance provisions of the Indenture.

46

In addition, the Company may, at its option and at any time, elect to terminate its obligations under “—Repurchase at the Option of Holders—Change of Control” and “—Asset Sales” and under the covenants described under “—Certain Covenants” (other than the covenant described under “—Merger, Consolidation or Sale of Assets”), the operation of the Cross-Acceleration Provision, the Judgment Provision, the Guarantee Default Provision and (with respect only to Significant Subsidiaries) the Bankruptcy Provision described under “—Events of Default and Remedies” above and the limitations contained in clause (4) of the first paragraph under “—Certain Covenants—Merger, Consolidation or Sale of Assets” above (collectively, “Covenant Defeasance”) and certain other covenants or obligations of the Company set forth in the Indenture, and thereafter any omission to comply with such obligations or provisions will not constitute a Default or Event of Default.

The Company may exercise its Legal Defeasance option notwithstanding its prior exercise of its Covenant Defeasance option. If the Company exercises its Legal Defeasance option, payment of the Notes may not be accelerated because of any Event of Default. If the Company exercises its Covenant Defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in clauses (4), (5), (6), (7), (8) or (with respect only to Significant Subsidiaries) (9) under “—Events of Default and Remedies” above or because of the failure of the Company to comply with clause (4) of the first paragraph under “—Certain Covenants—Merger, Consolidation or Sale of Assets” above. If the Company exercises its Legal Defeasance or Covenant Defeasance option, each Guarantor will be released from its obligations with respect to its Subsidiary Guarantee.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to Stated Maturity or to a particular redemption date; provided that if such redemption is made as provided in the second paragraph under “—Optional Redemption,” (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Make Whole Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money in trust on the redemption date as necessary to pay the Make Whole Premium as determined on or prior to such date (the amount of such additional money, the “Make Whole Deficit”) (it being understood that any Legal Defeasance or Covenant Defeasance shall be subject to the condition subsequent that such Make Whole Deficit is in fact paid); provided, further, that the Trustee shall have no liability whatsoever in the event that such Make Whole Deficit is not in fact paid after any Legal Defeasance or Covenant Defeasance. Any Make Whole Deficit will be set forth in an officers’ certificate delivered to the Trustee simultaneously with the deposit of such Make Whole Deficit that confirms that such Make Whole Deficit will be applied toward such redemption;

(2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

47

(4) no Default or Event of Default shall have occurred and be continuing on the date of such 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 any Lien securing such borrowings);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound;

(6) the Company must deliver to the Trustee an officers’ certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(7) the Company must deliver to the Trustee an officers’ certificate and an Opinion of Counsel, stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Satisfaction and Discharge

The Company may discharge its and the Guarantors’ obligations under the Indenture if (a) all outstanding Notes have been delivered to the Trustee for cancellation, (b) all outstanding Notes have become due and payable at their scheduled maturity or (c) all outstanding Notes are scheduled for redemption within one year by reason of a mailing of a notice of redemption or otherwise, and the Company has deposited with the Trustee an amount of cash in U.S. dollars sufficient to pay and discharge all outstanding Notes, not previously delivered for cancellation, on the date of their scheduled maturity or the scheduled date of redemption.

Amendment, Supplement and Waiver

Except as provided below, the Indenture, the Notes and the Subsidiary Guarantees may be amended with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing default or compliance with any provision of the Indenture, the Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for Notes).

Without the consent of each Holder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any Note or alter or waive the provisions with respect to the redemption of the Notes (other than provisions relating to the covenants described above under the caption “—Repurchase at the Option of Holders” or provisions relating to minimum notices required for redemption of Notes described under the caption “—Optional Redemption”);

(3) reduce the rate of or change the time for payment of interest on any Note;

(4) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes, except a Default in payments that have become due solely because of an acceleration of the Notes that has been rescinded;

(5) make any Note payable in a currency other than that stated in the Notes;

48

(6) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or premium, if any, or interest on the Notes (except as permitted by clause (2) above);

(7) release any Guarantor from its obligations under its Subsidiary Guarantee except in accordance with the terms of the Indenture; or

(8) make any change in the preceding amendment, supplement and waiver provisions.

Notwithstanding the preceding, without the consent of any Holder of Notes, the Company, the Guarantors and the Trustee may amend or supplement the Indenture, the Notes or the Subsidiary Guarantees:

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

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the Company’s or a Guarantor’s properties or assets in compliance with the Indenture;

(4) to add or release Guarantors in compliance with the Indenture;

(5) to make any change that would provide any additional rights or benefits to the Holders of Notes, add Events of Default or surrender any right or power conferred upon the Company or any Guarantor or that does not adversely affect in any material respect the legal rights under the Indenture of any such Holder;

(6) to conform the text of the Indenture, the Notes or the Subsidiary Guarantees to this “Description of the Exchange Notes”;

(7) to secure the Notes, including pursuant to the requirements of the covenant described above under the caption “—Certain Covenants—Liens”;

(8) to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act;

(9) to comply with requirements of any securities depository with respect to the Notes; or

(10) to provide for the issuance of the exchange notes or Additional Notes.

Concerning the Trustee

Wells Fargo Bank, National Association is the Trustee under the Indenture. Such bank has been appointed as the exchange agent in connection with the exchange offer.

If the Trustee becomes a creditor of the Company or any Guarantor, the Indenture will limit its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest after a Default has occurred and is continuing it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

The Holders of a majority in principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject

49

to certain exceptions. If an Event of Default shall occur and be continuing, the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent person under the circumstances in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any Holder of Notes, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense as provided in the Indenture.

Governing Law

The Indenture, the Notes and the Subsidiary Guarantees will be governed by, and construed in accordance with, the laws of the State of New York.

If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the average rate in effect from the beginning of such period to the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof).

Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate.

Book-Entry, Delivery and Form

The exchange notes initially will be represented by one or more notes in registered, global form without interest coupons (collectively, the “Global Notes”). The Global Notes will be deposited upon issuance with the trustee as custodian for DTC, and registered in the name of DTC or its nominee, 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).

Ownership of beneficial interests in a Global Note will be limited to persons who have accounts with DTC (“participants”) or persons who hold interests through participants.

Ownership of beneficial interests in a Global Note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Indirect access to the DTC system is available to organizations such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly (“indirect participants”).

So long as DTC, or its nominee, is the registered owner or holder of a Global Note, DTC or such nominee, as the case may be, will be considered the sole owner or holder of Notes represented by such Global Note for all purposes under the Indenture and the Note. No beneficial owner of an interest in a Global Note will be able to transfer that interest except in accordance with DTC’s applicable procedures, in addition to those provided for under the Indenture and, if applicable, those of Euroclear and Clearstream.

All payments on a Global Note will be made to DTC or its nominee, as the case may be, as the registered owner thereof. Neither the Company, the Guarantors, the Trustee nor any Paying Agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

The Company expects that DTC or its nominee, upon receipt of any payment in respect of a Global Note, will credit participants’ accounts on the applicable payment date with payments in amounts proportionate to their respective beneficial interests in the principal amount of such Global Note as shown on the records of DTC. The Company also expects that payments by participants to owners of beneficial interests in a Global Note held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of the participants.

Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. Transfers between participants in Euroclear and Clearstream will be effected in the ordinary way in accordance with their respective rules and operating procedures.

The Company expects that DTC will take any action permitted to be taken by a holder of Notes (including the presentation of Notes for exchange as described below) only at the direction of one or more participants to

72

whose account DTC interests in a Global Note are credited and only in respect of such portion of the aggregate principal amount of Notes as to which such participant or participants has or have given such direction. However, if there is an Event of Default under the Notes, DTC reserves the right to exchange the applicable Global Note for Notes in certificated form (“Certificated Notes”), which it will distribute to its participants and which may be legended as set forth under the heading “Transfer Restrictions.”

The Company understands that: DTC is a limited purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates.

Although DTC, Euroclear and Clearstream are expected to follow the foregoing procedures described in this section of the prospectus in order to facilitate transfers of interests in a Global Note among participants of DTC, Euroclear and Clearstream, they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither the Company, the Guarantors, the Trustee nor any Paying Agent 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.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of the material U.S. federal income tax considerations relevant to the exchange of outstanding notes for exchange 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 (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 exchange notes. 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 outstanding notes for exchange notes, including the applicability and effect of any foreign, state, local or other tax laws or estate or gift tax considerations.

The exchange of outstanding notes for exchange notes pursuant to the exchange offer will not constitute a taxable event for U.S. federal income tax purposes. As a result, (1) a holder will not recognize a taxable gain or loss as a result of exchanging such holder’s outstanding notes for exchange notes, (2) the holding period of the exchange notes will include the holding period of the outstanding notes exchanged therefor, and (3) the adjusted tax basis of the exchange notes will be the same as the adjusted tax basis of the outstanding notes exchanged therefor immediately before such exchange.

74

PLAN OF DISTRIBUTION

Based on interpretations by the staff of the SEC in no-action letters issued to third parties, we believe that you may transfer exchange notes issued under the exchange offer in exchange for the outstanding notes if:

You may not participate in the exchange offer unless:

Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver this prospectus in connection with any resale of such exchange notes. To date, the staff of the SEC has taken the position that broker-dealers may fulfill their prospectus delivery requirements with respect to transactions involving an exchange of securities such as this exchange offer, other than a resale of an unsold allotment from the original sale of the outstanding notes, with this prospectus. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received for their own account in exchange for outstanding notes where such outstanding notes were acquired as a result of market-making activities or other trading activities. We have agreed that, for a period of 180 days after the date of this prospectus, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until such date, all dealers effecting transactions in exchange notes may be required to deliver this prospectus.

We are entitled under the Registration Rights Agreements to suspend the use of this prospectus by broker-dealers if, in our good faith determination, the continued effectiveness of the registration statement and the use of this prospectus would require the public disclosure of material non-public information.

If we suspend the use of this prospectus, the period referred to above during which we have agreed to make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with certain resales, will be extended by a number of days equal to the period of the suspension and we and the Guarantors will pay additional interest, if required, pursuant to the Registration Rights Agreements.

If you wish to exchange notes for your outstanding notes in the exchange offer, you will be required to make representations to us as described in “The Exchange Offer—Procedures for Tendering—Your Representations to Us” in this prospectus. As indicated in the letter of transmittal, you will be deemed to have made these representations by tendering your outstanding notes in the exchange offer. In addition, if you are a broker-dealer who receives exchange notes for your own account in exchange for outstanding notes that were acquired by you as a result of market-making activities or other trading activities, you will be required to acknowledge, in the same manner, that you will deliver this prospectus in connection with any resale by you of such exchange notes.

We will not receive any proceeds from any sale of exchange notes by broker-dealers. Exchange notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions:

75

Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such exchange notes. Any broker-dealer that resells exchange notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such exchange notes may be deemed to be an “underwriter” within the meaning of the Securities Act. Each letter of transmittal states that by acknowledging that it will deliver and by delivering this prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 180 days after the consummation of the exchange offer, the Company will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents as provided in the Letter of Transmittal. The Company has agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the Holders of the outstanding notes) other than commissions or concessions of any brokers or dealers and will indemnify the Holders of the outstanding notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this prospectus and the documents incorporated by reference herein constitute “forward-looking statements.” Additionally, forward-looking statements may be made orally or in press releases, conferences, reports, on our website or otherwise, in the future, by us or on our behalf. Such statements are generally identifiable by the terminology used such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “potential,” “predict,” “project,” “should,” “would” or other similar words.

By their very nature, forward-looking statements require us to make assumptions that may not materialize or that may not be accurate. Forward-looking statements are subject to known and unknown risks and uncertainties and other factors that may cause actual results, levels of activity and achievements to differ materially from those expressed or implied by such statements. Such factors include, among others: general economic conditions, changes in oil, natural gas and natural gas liquids prices and the demand for oil, natural gas and natural gas liquids, the success of our drilling program, the timing and amount of planned capital expenditures, the sufficiency of our cash flow from operations together with available borrowing capacity under our credit agreement, uncertainties in estimating proved reserves and forecasting production results, operational factors affecting the commencement or maintenance of producing wells, the condition of the capital markets generally, as well as our ability to access them, the proximity to our properties and capacity of transportation facilities, availability of acquisitions, our ability to integrate acquisitions with our business, weather and environmental conditions, uncertainties regarding environmental regulations or litigation and other legal or regulatory developments affecting our business, and the other factors discussed below and elsewhere in this prospectus supplement and in other documents that we file with or furnish to the SEC, all of which are difficult to predict. Forward-looking statements may include statements about:

79

Although we believe that the expectations conveyed by the forward-looking statements are reasonable based on information available to us on the date such forward-looking statements were made, no assurances can be given as to future results, levels of activity, achievements or financial condition.

You should not place undue reliance on any forward-looking statement and should recognize that the statements are predictions of future results, which may not occur as anticipated. Actual results could differ materially from those anticipated in the forward-looking statements and from historical results, due to the risks and uncertainties described above, as well as others not now anticipated. The impact of any one factor on a particular forward-looking statement is not determinable with certainty as such factors are interdependent upon other factors. The foregoing statements are not exclusive and further information concerning us, including factors that potentially could materially affect our financial results, may emerge from time to time. We undertake no obligation to update forward-looking statements to reflect actual results or changes in factors or assumptions affecting such forward-looking statements, except as required by law, including the securities laws of the United States and the rules and regulations of the SEC.
