PROSPECTUS SUMMARY

This summary highlights information included or incorporated by reference in this prospectus. It may not contain all of the information that is important to you. This prospectus includes information about the exchange offer and includes or incorporates by reference information about our business and our financial and operating data. Before deciding to participate in the exchange offer, you should read this entire prospectus carefully, including the financial data and related notes incorporated by reference in this prospectus and the “Risk Factors” section beginning on page 8 of this prospectus.

In this prospectus we refer to the 8.500% Senior Notes due 2019 to be issued in the exchange offer as the “new notes” and the $300,000,000 principal amount of our 8.500% Senior Notes due 2019 issued on October 24, 2012 as the “old notes.” The old notes were offered as additional notes under the indenture, dated as of June 10, 2011, pursuant to which we issued $600,000,000 principal amount of our 8.500% Senior Notes due 2019 on June 10, 2011, which were subsequently exchanged for registered notes in January 2012, which we refer to herein as the “existing registered notes.” We refer to the new notes, the old notes and the existing registered notes collectively as the “notes.”

W&T Offshore, Inc.

W&T Offshore, Inc. is an independent oil and natural gas producer focused primarily in the Gulf of Mexico and Texas. We have grown through acquisitions, exploration and development and currently hold working interests in 67 producing offshore fields in federal and state waters including the deepwater. During 2011, we expanded onshore into West Texas and East Texas where we are actively pursuing exploration and development activities. However, the majority of our daily production is derived from wells we operate offshore. In managing our business, we are concerned primarily with maximizing long-term return on shareholders’ equity. To accomplish this primary goal, we focus on profitably increasing production and finding oil and gas reserves at a favorable cost. We strive to increase our reserves and production through acquisitions and our drilling programs. We have focused on acquiring properties where we can develop an inventory of drilling prospects that will enable us to continue to add reserves post-acquisition. We believe attractive acquisition opportunities will continue to arise in the Gulf of Mexico and onshore as other oil and gas companies continue to divest properties as they shift their regional focus and increase their participation in larger, more capital intensive projects.

Our exploration efforts historically have been in areas in reasonably close proximity to known proved reserves, which we believe reduces our risks. Historically, we have financed our exploratory drilling with net cash provided by our operating activities. The investment associated with drilling an offshore well and future development of an offshore project principally depends upon water depth, the depth of the well, the complexity of the geological formations involved and whether the well or project can be connected to existing infrastructure or will require additional investment in infrastructure. Deepwater and deep shelf drilling projects can be substantially more capital intensive than those on the conventional shelf and onshore. Certain risks are inherent in the oil and natural gas industry and our business, any one of which, if it occurs, can negatively impact our rate of return on shareholders’ equity. When projects are extremely capital intensive and involve substantial risk, we often seek participants to share the risk. Onshore wells are less capital intensive than offshore wells, but the amount of reserves discovered and developed on a per well basis has historically been less than offshore wells.

We are a Texas corporation. Our principal executive offices are located at Nine Greenway Plaza, Suite 300, Houston, Texas 77046. Our telephone number is (713) 626-8525. We maintain a website at www.wtoffshore.com, which contains information about us. Our website and the information contained on it and connected to it are not incorporated by reference into this prospectus.

Exchange Offer

On October 24, 2012, we completed a private offering of the old notes. We entered into a registration rights agreement with the initial purchasers in the private offering in which we agreed to deliver to you this prospectus and to use commercially reasonable efforts to complete the exchange offer within 365 days after the date we issued the old notes.

Exchange Offer

We are offering to exchange new notes for old notes.

Expiration Date

The exchange offer will expire at 5:00 p.m., New York City time, on , 2013, unless we decide to extend it.

Condition to the Exchange Offer

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

Procedures for Tendering Old Notes

To participate in the exchange offer, you must follow the procedures established by The Depository Trust Company, which we call “DTC,” for tendering notes held in book-entry form. These procedures are part of DTC’s Automated Tender Offer Program, which we call “ATOP,” and require that (i) the exchange agent receive, prior to the expiration date of the exchange offer, a computer generated message known as an “agent’s message” that is transmitted through DTC’s automated tender offer program, and (ii) DTC confirm that:

•

DTC has received your instructions to exchange your notes, and

•

you agree to be bound by the terms of the letter of transmittal.

For more information on tendering your old notes, please refer to the section in this prospectus entitled “Exchange Offer—Terms of the Exchange Offer” and “—Procedures for Tendering.”

Guaranteed Delivery Procedures

None.

Withdrawal of Tenders

You may withdraw your tender of old notes at any time prior to the expiration of the exchange offer. To withdraw, you must submit a notice of withdrawal to the exchange agent using the ATOP procedures before 5:00 p.m., New York City time, on the expiration date of the exchange offer. Please refer to the section in this prospectus entitled “Exchange Offer—Withdrawal of Tenders.”

Acceptance of Old Notes and Delivery of New Notes

If you fulfill all conditions required for proper acceptance of old notes, we will accept any and all old notes that you properly tender in the exchange offer before 5:00 p.m., New York City time, on the expiration date. We will return any old note that we do not accept for exchange to you without expense promptly after the expiration date and acceptance of the old notes for exchange. Please refer to the section in this prospectus entitled “Exchange Offer—Terms of the Exchange Offer.”

Fees and Expenses

We will bear expenses related to the exchange offer. Please refer to the section in this prospectus entitled “Exchange Offer—Fees and Expenses.”

Use of Proceeds

The issuance of the new notes will not provide us with any new proceeds. We are making this exchange offer solely to satisfy our obligations under our registration rights agreement.

Consequences of Failure to Exchange Old Notes

If you do not exchange your old notes in this exchange offer, you will no longer be able to require us to register the old notes under the Securities Act of 1933 (the “Securities Act”) except in limited circumstances provided under the registration rights agreement. In addition, you will not be able to resell, offer to resell or otherwise transfer the old notes unless we have registered the old notes under the Securities Act, or unless you resell, offer to resell or otherwise transfer them under an exemption from the registration requirements of, or in a transaction not subject to, the Securities Act.

U.S. Federal Income Tax Consequences

The exchange of new notes for old notes in the exchange offer will not be a taxable event for U.S. federal income tax purposes. Please read “Material United States Federal Income Tax Consequences.”

Exchange Agent

We have appointed Wells Fargo Bank, National Association as exchange agent for the exchange offer. You should direct questions and requests for assistance, requests for additional copies of this prospectus or the letter of transmittal to the exchange agent addressed as follows:

Eligible institutions may make requests by facsimile at (612) 667-6282 and may confirm facsimile delivery by calling (800) 344-5128.

Terms of the New Notes

The new notes will be identical to the old notes except that the new notes are registered under the Securities Act and will not have restrictions on transfer, registration rights or provisions for additional interest. The new notes will evidence the same debt as the old notes, and the same indenture will govern the new notes and the old notes. The old notes were offered as additional notes under the indenture, dated as of June 10, 2011, pursuant to which we issued the existing registered notes.

The following summary contains basic information about the new notes and is not intended to be complete. It does not contain all information that may be important to you. For a more complete understanding of the new notes, please refer to the section entitled “Description of the Notes” in this prospectus.

Issuer

W&T Offshore, Inc.

Notes Offered

$300,000,000 aggregate principal amount of 8.500% senior notes due 2019.

Maturity

June 15, 2019.

Interest Payment Dates

Interest on the notes is paid semi-annually in arrears on June 15 and December 15 of each year, with the next interest payment being due on June 15, 2013. Interest on each new note will accrue from December 15, 2012, the last interest payment date on which interest was paid on the old notes.

Guarantees

Our obligations under the new notes will be fully and unconditionally guaranteed on a senior unsecured basis by our existing material subsidiaries and by certain of our future subsidiaries. See “Description of the Notes—Guarantees.”

Ranking

The new notes will be our general unsecured senior obligations. Accordingly, they will rank:

•

effectively subordinate to our existing and future secured indebtedness, including indebtedness under our Fourth Amended and Restated Credit Agreement, as amended, (the “Credit Agreement”), to the extent of the value of the collateral securing such indebtedness;

•

effectively subordinate to all existing and future indebtedness and other liabilities of any non-guarantor subsidiaries (other than indebtedness and liabilities owed to us);

•

pari passu in right of payment to all of our existing and future senior indebtedness; and

•

senior in right of payment to any of our future subordinated indebtedness.

The new notes will be jointly and severally guaranteed on a senior unsecured basis by each of our existing material subsidiaries and certain future subsidiaries. Each subsidiary guarantee will rank:

•

effectively subordinate to all existing and future secured indebtedness of the guarantor subsidiary, including its guarantee of indebtedness under our Credit Agreement, to the extent of the value of the collateral securing such indebtedness;

•

pari passu in right of payment to all existing and future senior indebtedness of the guarantor subsidiary; and

•

senior in right of payment to any future subordinated indebtedness of the guarantor subsidiary.

Optional Redemption

On or after June 15, 2015, we may redeem the notes, in whole or in part, at the redemption prices set forth under “Description of the Notes—Optional Redemption.”

Prior to June 15, 2014, we may on one or more occasions redeem up to 35% of the aggregate principal amount of the notes with the net cash proceeds of certain equity offerings, at a price equal to 108.500% of the aggregate principal amount of the notes plus accrued and unpaid interest.

In addition, prior to June 15, 2015, we may redeem all or part of the notes at a redemption price equal to 100% of the aggregate principal amount of the notes to be redeemed, plus a make-whole premium and accrued and unpaid interest.

Change of Control and Asset Sales

If we experience a change of control or if we sell certain assets and do not apply the proceeds as required, we will be required to offer to repurchase the notes at the prices set forth in under “Description of the Notes—Repurchase at the Option of Holders.”

Certain Covenants

The indenture governing the notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

•

make investments;

•

incur additional indebtedness or issue preferred stock;

•

create certain liens;

•

sell assets;

•

enter into agreements that restrict dividends or other payments from our subsidiaries to us;

•

consolidate, merge or transfer all or substantially all of the assets of our company;

•

engage in transactions with our affiliates;

•

pay dividends or make other distributions on capital stock or subordinated indebtedness; and

•

create unrestricted subsidiaries.

These covenants are subject to important exceptions and qualifications. In addition, most of the covenants will terminate if both Standard & Poor’s Ratings Services and Moody’s Investors Service, Inc. assign the notes an investment grade rating and no default exists with respect to the notes. See “Description of the Notes—Certain Covenants.”

No Prior Market

Certain of the initial purchasers of the old notes have maintained a market in the existing registered notes. It is anticipated that after the old notes are exchanged for the new notes, the new notes and existing registered notes will trade together under the same CUSIP number. Although certain of the initial purchasers informed us at the time of issuance of the old notes that they intended to continue to make a market in the notes, they are not obligated to do so, and may discontinue market making at any time without notice. Accordingly, a liquid market for the notes may not be maintained. We do not intend to apply for a listing of the notes on any securities exchange or any automated dealer quotation system.

Risk Factors

Investing in the notes involves risks. See “Risk Factors” beginning on page 8 for a discussion of certain factors you should consider in evaluating an investment in the new notes.

(1)	Earnings were inadequate to cover fixed charges for the year ended December 31, 2008 by $846.5 million. Earnings for the year ended December 31, 2008 included an impairment write down of $1,182.8 million.

(2)	Earnings were inadequate to cover fixed charges for the year ended December 31, 2009 by $266.0 million. Earnings for the year ended December 31, 2009 included an impairment write down of $218.9 million.

For purposes of computing the ratio of earnings to fixed charges, “earnings” consists of the sum of pre-tax income from continuing operations before income or loss from equity investees, adjusted to reflect actual distributions from equity investments, fixed charges, amortization of capitalized interest less interest capitalized and the non-controlling interest in pre-tax income of subsidiaries that have not incurred fixed charges. “Fixed charges” consists of the sum of interest costs expensed and capitalized, amortized discounts and debt issue costs related to indebtedness and the portion of rental expense, which we believe represents an interest factor.

You should carefully consider the information included or incorporated by reference in this prospectus, including the matters addressed under “Cautionary Statement Regarding Forward-Looking Statements,” and the following risks before deciding to participate in the exchange offer. In addition, you should read the risk factors in our Annual Report on Form 10-K for the year ended December 31, 2011, which is incorporated by reference in this prospectus and, to the extent applicable, any subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

If you do not properly tender your old notes, you will continue to hold unregistered old notes and your ability to transfer old notes will remain restricted and may be adversely affected.

We will only issue new notes in exchange for old notes that you timely and properly tender. Therefore, you should allow sufficient time to ensure timely delivery of the old notes and you should carefully follow the instructions on how to tender your old notes. Neither we nor the exchange agent is required to tell you of any defects or irregularities with respect to your tender of old notes.

If you do not exchange your old notes for new notes pursuant to the exchange offer, the old notes you hold will continue to be subject to the existing transfer restrictions. In general, you may not offer or sell the old notes except under an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not plan to register old notes under the Securities Act unless our registration rights agreement with the initial purchasers of the old notes requires us to do so. Further, if you continue to hold any old notes after the exchange offer is consummated, you may have trouble selling them because there will be fewer of these notes outstanding.

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

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

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

Any alternative financing plans that we undertake, if necessary, may not allow us to meet our debt obligations. Our inability to generate sufficient cash flow to satisfy our debt obligations, including our obligations under the notes, or to obtain alternative financing, could materially and adversely affect our business, financial condition, results of operations and prospects.

Our debt obligations could have important consequences. For example, they could:

In addition, if we fail to comply with the covenants or other terms of any agreements governing our debt, our lenders will have the right to accelerate the maturity of that debt and foreclose upon the collateral, if any, securing that debt. Realization of any of these factors could adversely affect our financial condition, results of operations and cash flows.

The notes and the guarantees are unsecured and effectively subordinated to our existing secured indebtedness and any future secured indebtedness.

The notes and the guarantees are general unsecured senior obligations ranking effectively junior in right of payment to all existing and future secured debt of ours and that of each subsidiary guarantor, including obligations under our Credit Agreement, to the extent of the value of the collateral securing the debt.

If we or a subsidiary guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any secured debt of ours or that subsidiary guarantor will be entitled to be paid in full from our assets or the assets of the guarantor, as applicable, securing that debt before any payment may be made with respect to the notes or the affected guarantees. Holders of the notes will participate ratably in our remaining assets with all holders of our unsecured indebtedness that does not rank junior to the notes, including all of our other general creditors, based upon the respective amounts owed to each holder or creditor. In any of the foregoing events, there may not be sufficient assets to pay amounts due on the notes. As a result, holders of the notes would likely receive less, on a ratable basis, than holders of secured indebtedness.

We may be able to incur substantially more debt. This could exacerbate the risks associated with our indebtedness.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of the indenture do not prohibit us or our subsidiaries from doing so. As of September 30, 2012, on a pro forma basis after giving effect to the offering of the old notes, the amendment to the Credit Agreement and the application of the net proceeds from the sale of the old notes, we and our subsidiary guarantors would have had no secured debt outstanding and we would have had $725 million available for future borrowings under our revolving credit facility.

These borrowings could be secured, and as a result, effectively senior to the notes and the guarantees of the notes by our subsidiary guarantors, to the extent of the value of the collateral securing that indebtedness. If we incur any additional indebtedness that ranks equally with the notes, the holders of that debt will be entitled to share ratably with the holders of these notes in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of us. This may have the effect of reducing the amount of proceeds paid to you.

If new debt is added to our current debt levels, the related risks that we and our subsidiaries now face could intensify. Our level of indebtedness may prevent us from engaging in certain transactions that might otherwise be beneficial to us by limiting our ability to obtain additional financing, limiting our flexibility in operating our business or otherwise. In addition, we could be at a competitive disadvantage against other less leveraged competitors that have more cash flow to devote to their business. Any of these factors could result in a material adverse effect on our business, financial condition, results of operations, business prospects and ability to satisfy our obligations under the notes.

Restrictions in our existing and future debt agreements could limit our growth and our ability to respond to changing conditions.

The indenture governing the notes and our Credit Agreement contain, and agreements governing our future indebtedness may contain, a number of significant covenants in addition to covenants restricting the incurrence of additional debt. These covenants limit our ability and the ability of our restricted subsidiaries, among other things, to:

Our Credit Agreement requires us, among other things, to maintain certain financial ratios, satisfy certain financial condition tests or reduce our debt. These restrictions may also limit our ability to obtain future financings, withstand a future downturn in our business or the economy in general, or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of the limitations that the restrictive covenants under the indenture governing the notes and the Credit Agreement impose on us.

A breach of any covenant in the indenture governing the notes and our Credit Agreement would result in a default under that agreement after any applicable grace periods. A default, if not waived, could result in acceleration of the debt outstanding under the agreement and in a default with respect to, and acceleration of, the debt outstanding under any other debt agreement. The accelerated debt would become immediately due and payable. If that should occur, we may not be able to make all of the required payments or borrow sufficient funds to refinance it. Even if new financing were then available, it may not be on terms that are acceptable to us. See “Description of the Notes—Events of Default and Remedies.”

If we experience certain kinds of changes of control, we must give holders of the notes the opportunity to sell us their notes at 101% of their principal amount, plus accrued and unpaid interest. However, in such an event, we might not be able to pay you the required repurchase price for the notes you present to us because we might not have sufficient funds available at that time, or the terms of our Credit Agreement or other agreements we may enter into in the future may prevent us from applying funds to repurchase the notes. The source of funds for any

repurchase required as a result of a change of control will be our available cash or cash generated from our oil and gas operations or other sources, including:

Sufficient funds may not be available at the time of any change of control to repurchase your notes after first repaying any of our senior secured debt that may exist at the time. In addition, restrictions under our Credit Agreement do not, and any future credit facilities may not, allow such repurchases. A “change of control” (as defined in the indenture for the notes) would also be an event of default under our Credit Agreement that would permit the lenders to accelerate the debt outstanding under the Credit Agreement. Finally, using available cash to fund the potential consequences of a change of control may impair our ability to obtain additional financing in the future, which could negatively impact our ability to conduct our business operations.

A financial failure by us or our subsidiaries may result in the assets of any or all of those entities becoming subject to the claims of all creditors of those entities.

A financial failure by us or our subsidiaries could affect payment of the notes if a bankruptcy court were to substantively consolidate us and our subsidiaries. If a bankruptcy court substantively consolidated us and our subsidiaries, the assets of each entity would be subject to the claims of creditors of all entities. This would expose you not only to the usual impairments arising from bankruptcy, but also to potential dilution of the amount ultimately recoverable because of the larger creditor base. Furthermore, forced restructuring of the notes could occur through the cram-down provision of the bankruptcy code. Under this provision, the notes could be restructured over your objections as to their general terms, primarily interest rate and maturity.

If the subsidiary guarantees are deemed fraudulent conveyances or preferential transfers, a court may subordinate or void them.

Under various fraudulent conveyance or fraudulent transfer laws, a court could subordinate or void our subsidiary guarantees. Generally, a United States court may void or subordinate a subsidiary guarantee in favor of the subsidiary’s other obligations if it finds that at the time the subsidiary entered into a subsidiary guarantee it:

In addition, a guarantee may be voided based on the level of benefits that the subsidiary guarantor received compared to the amount of the subsidiary guarantee. If a subsidiary guarantee is voided or held unenforceable, you would not have any claim against that subsidiary and would be creditors solely of us and any subsidiary guarantors whose guarantees are not held unenforceable. After providing for all prior claims, there may not be sufficient assets to satisfy claims of holders of notes relating to any voided portions of any of the subsidiary guarantees.

A subsidiary guarantee could be voided by a court as a preferential transfer. In addition, a court could require holders of notes to return any payments made on the notes during the 90-day (or, in certain cases, one-year) period.

The old notes have not been registered under the Securities Act, and may not be resold by holders thereof unless the old notes are subsequently registered or an exemption from the registration requirements of the Securities Act is available. However, we cannot assure you that, even following exchange of the old notes for new notes, that an active trading market for the notes will be maintained, and we will have no obligation to create such a market. At the time of the private placement of the old notes, certain initial purchasers maintained a market in the existing registered notes and they informed us that they intended to continue to make a market in the notes. The initial purchasers are not obligated, however, to make a market in the notes and any market making may be discontinued at any time at their sole discretion. No assurance can be given as to the liquidity of or trading market for the notes.

We do not intend to apply for a listing of the notes on any securities exchange or any automated dealer quotation system. The liquidity of any trading market for the notes and the market price quoted for the notes will depend upon the number of holders of the notes, the overall market for high yield securities, our financial performance or prospects or the prospects for companies in our industry generally, the interest of securities dealers in making a market in the notes and other factors.

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

Many of the covenants in the indenture governing the notes will terminate if the notes are rated investment grade by both Standard & Poor’s and Moody’s, provided at such time no default with respect to the notes has occurred and is continuing. The covenants restrict, among other things, our ability to pay dividends, incur debt and to enter into certain other transactions. There can be no assurance that the notes will ever be rated investment grade, or that if they are rated investment grade, that the notes will maintain such ratings. However, termination of these covenants would allow us to engage in certain transactions that would not be permitted while these covenants were in force. Please see “Description of the Notes—Certain Covenants—Termination of Covenants.”

At the closing of the offering of the old notes, we entered into a registration rights agreement with the initial purchasers pursuant to which we agreed, for the benefit of the holders of the old notes, at our cost, to:

Additionally, we agreed to offer to holders of the old notes the new notes in exchange for surrender of the old notes upon the SEC’s declaring the exchange offer registration statement effective. We agreed to use commercially reasonable efforts to cause the exchange offer registration statement to be effective continuously, and to keep the exchange offer open for a period of not less than 30 calendar days.

For each old note surrendered to us pursuant to the exchange offer, the holder of such old note will receive a new note having a principal amount equal to that of the surrendered old note. Interest on each new note will accrue from the last interest payment date on which interest was paid on the surrendered old note, December 15, 2012. The registration rights agreement also provides an agreement to include in the prospectus for the exchange offer certain information necessary to allow a broker-dealer who holds old notes that were acquired for its own account as a result of market-making activities or other ordinary course trading activities (other than old notes acquired directly from us or one of our affiliates) to exchange such old notes pursuant to the exchange offer and to satisfy the prospectus delivery requirements in connection with resales of new notes received by such broker-dealer in the exchange offer. We agreed to use commercially reasonable efforts to maintain the effectiveness of the exchange offer registration statement for these purposes for a period ending on the earlier of 180 days from the date the exchange offer registration statement is declared effective and the date on which broker-dealers are no longer required to deliver a prospectus in connection with market-making or other trading activities.

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

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

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

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

We have agreed, at our expense, (i) as promptly as reasonably practicable, and in any event on or prior to the 30th calendar day after such filing obligation arises, file a shelf registration statement, (ii) to use our commercially reasonable efforts to cause the shelf registration statement to be declared effective under the Securities Act on or prior to the 120th calendar day after such filing obligation arises, and (iii) to keep effective the shelf registration statement until two years after its effective date (or such shorter period that will terminate when all the notes covered thereby have been sold pursuant thereto or in certain other circumstances).

If either (a) the exchange offer is not consummated on or prior to the 365th calendar day following the date of issuance of the old notes, (b) a shelf registration statement applicable to the notes is not filed or declared effective when required, or (c) a registration statement applicable to the notes is declared effective as required but thereafter fails to remain effective or usable in connection with resales for more than 30 calendar days (each such event referred to in clauses (a) through (c) above, a “Registration Default”), we will pay liquidated damages in the form of additional interest in cash to each holder of notes in an amount equal to 0.25% per annum of the aggregate principal amount of notes for the period immediately following the occurrence of the Registration Default until such time as no Registration Default is in effect, which rate shall increase by 0.25% per annum for each subsequent 90-day period during which such Registration Default continues up to a maximum of 0.50% per annum. Following the cure of all Registration Defaults, such additional interest will cease to accrue and the interest rate on the notes will revert to the original rate; provided, however, that, if after the date such additional interest ceases to accrue, a different Registration Default occurs, such additional interest may again commence accruing pursuant to the foregoing provisions. All references herein to “interest” include any additional interest payable pursuant to this paragraph.

Holders of the old notes will be required to make certain representations to us (as described in the registration rights agreement) in order to participate in the exchange offer and will be required to deliver information to be used in connection with the shelf registration statement.

This summary of the material provisions of the registration rights agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the registration rights agreement, a copy of which is filed as an exhibit to the registration statement of which this prospectus is a part.

Except as set forth above, after consummation of the exchange offer, holders of old notes which are the subject of the exchange offer have no registration or exchange rights under the registration rights agreement. See “—Consequences of Failure to Exchange.”

Subject to the terms and conditions described in this prospectus and in the letter of transmittal, we will accept for exchange any old notes properly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the expiration date. We will issue new notes in principal amount equal to the principal amount of old notes

surrendered in the exchange offer. Old notes may be tendered only for new notes and only in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

The exchange offer is not conditioned upon any minimum aggregate principal amount of old notes being tendered for exchange.

As of the date of this prospectus, $300,000,000 in aggregate principal amount of the old notes is outstanding. This prospectus and the letter of transmittal are being sent to all registered holders of old notes. There will be no fixed record date for determining registered holders of old notes entitled to participate in the exchange offer.

We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act of 1933 and the Securities Exchange Act of 1934 and the rules and regulations of the SEC. Old notes that the holders thereof do not tender for exchange in the exchange offer will remain outstanding and continue to accrue interest. These old notes will continue to be entitled to the rights and benefits such holders have under the indenture relating to the notes.

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

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

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

The exchange offer will expire at 5:00 p.m., New York City time, on , 2013, unless, in our sole discretion, we extend it.

We expressly reserve the right, at any time or various times, to extend the period of time during which the exchange offer is open. We may delay acceptance of any old notes by giving oral (promptly followed in writing) or written notice of such extension to their holders. During any such extensions, all old notes previously tendered will remain subject to the exchange offer, and we may accept them for exchange.

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

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

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

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

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

In addition, we will not be obligated to accept for exchange the old notes of any holder that has not made to us the representations described under “—Purpose and Effect of the Exchange Offer,” “—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 new notes under the Securities Act.

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

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

These conditions are for our sole benefit, and we may assert them or waive them in whole or in part at any time or at various times in our sole discretion. 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.

In order to participate in the exchange offer, you must properly tender your old notes to the exchange agent as described below. It is your responsibility to properly tender your notes. We have the right to waive any defects. However, we are not required to waive defects and are not required to notify you of defects in your tender.

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

All of the old notes were issued in book-entry form, and all of the old notes are currently represented by global certificates held for the account of DTC. We have confirmed with DTC that the old notes may be tendered using ATOP instituted by DTC. 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 old notes to the exchange agent using the ATOP procedures. In connection with each transfer, DTC will send an “agent’s message” to the exchange agent. The agent’s message will be deemed to state that DTC has received instructions from the participant to tender old notes and that the participant agrees to be bound by the terms of the letter of transmittal.

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

We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered old notes and withdrawal of tendered old notes. Our determination will be final and binding. We reserve the absolute right to reject any old notes not properly tendered or any old notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defect, irregularities or conditions of tender as to particular old notes. Our interpretation of the terms and conditions of the exchange 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 old notes must be cured within such time as we shall determine. Although we intend to notify holders of defects or irregularities with respect to tenders of old notes, neither we, the exchange agent nor any other person will incur any liability for failure to give such notification. Tenders of old notes will not be deemed made until such defects or irregularities have been cured or waived. Any old notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the tendering holder, unless otherwise provided in the letter of transmittal, promptly following the expiration date.

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

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

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

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. For a withdrawal to be effective you must comply with the appropriate procedures of DTC’s ATOP system. Any notice of withdrawal must specify the name and number of the account at DTC to be credited with withdrawn old notes and otherwise comply with the procedures of DTC.

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

Any old notes that have been tendered for exchange but are not exchanged for any reason will be credited to an account maintained with DTC for the old notes. This crediting will take place as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. You may retender properly withdrawn old notes by following the procedures described under “—Procedures for Tendering” above at any time prior to 5:00 p.m., New York City time, on the expiration date.

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

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

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

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

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

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

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

You can find the definitions of certain terms used in this description under the subheading “—Certain Definitions.” In this description, the term “W&T,” “us,” “our” or “we” refers only to W&T Offshore, Inc. and not to any of its subsidiaries. References to the “existing registered notes” are to the $600 million aggregate principal amount of 8.500% Senior Notes due 2019 initially issued on June 10, 2011, which were subsequently exchanged for registered notes in January 2012. References to the “notes” in this section of the prospectus include the existing registered notes, the old notes issued on October 24, 2012 and the new notes, unless the context otherwise requires.

The new notes will be issued and the old notes were issued under an indenture dated as of June 10, 2011, among W&T, the Guarantors and Wells Fargo Bank, National Association, as trustee. The old notes were offered as additional notes under the same indenture that governs the existing registered notes. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act.

The following description is a summary of the material provisions of the indenture. It does not restate the agreement in its entirety. We urge you to read the indenture because it defines the rights of holders of the notes. A copy of the indenture is filed as an exhibit to the registration statement of which this prospectus is a part.

You can find the definition of various terms used in this “Description of the Notes” under “—Certain Definitions” below. Certain defined terms used in this description but not defined below under “—Certain Definitions” have the meanings assigned to them in the indenture.

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

If the exchange offer contemplated by this prospectus is consummated, holders of old notes who do not exchange those notes for new notes in the exchange offer will vote together with holders of the existing registered notes and the new notes for all relevant purposes under the indenture. In that regard, the indenture requires that certain actions by the holders thereunder must be taken, and certain rights must be exercised, by specified minimum percentages of the aggregate principal amount of the outstanding securities issued under 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 old notes that remain outstanding after the exchange offer will be aggregated with the existing registered notes and the new notes, and the holders of such existing registered notes, the old notes and the new notes will vote together as a single class for all such purposes. Accordingly, all references herein to specified percentages in aggregate principal amount of the notes outstanding shall be deemed to mean, at any time after the exchange offer is consummated, such percentages in aggregate principal amount of the existing registered notes, the old notes and the new notes then outstanding.

See “Risk Factors—Risks Relating to the Notes—The notes and the guarantees are unsecured and effectively subordinated to our existing secured indebtedness and any future secured indebtedness.”

The new notes, like the existing registered notes and the old notes, will be guaranteed by each of W&T’s existing Subsidiaries, other than White Shoal Pipeline Corporation. In the event of a bankruptcy, liquidation or reorganization of any non-guarantor Subsidiary, the non-guarantor Subsidiary will pay the holders of its debt and its trade creditors before it will be able to distribute any of its assets to W&T.

Any future Domestic Subsidiaries of W&T that has Indebtedness outstanding in excess of a Minimum Amount or guarantees other Indebtedness of W&T or of a Guarantor in excess of a Minimum Amount will be required to guarantee the notes as set forth below under the caption “—Certain Covenants—Additional Note Guarantees.”

Currently, all of our Subsidiaries are “Restricted Subsidiaries.” However, under the circumstances described below under the caption “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” we may designate certain of our existing or future Subsidiaries as “Unrestricted Subsidiaries.” Our Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indenture. Our Unrestricted Subsidiaries will not guarantee the notes.

W&T issued $300.0 million in aggregate principal amount of old notes on October 24, 2012. The old notes were issued as additional notes under the indenture governing the $600.0 million in aggregate principal amount of existing registered notes. In addition to the new notes issued in the exchange offer, W&T may again issue additional notes under the indenture from time to time after this exchange offer. Any further issuance of additional notes is subject to all of the covenants in the indenture, including the covenant described below under the caption “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.” The existing registered notes, the old notes, the new notes and any additional notes subsequently issued under the indenture will be treated as a single class for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. The new notes will be issued in minimum denominations of $1,000 and integral multiples of $1,000. The notes mature on June 15, 2019.

Interest on the notes accrues at the rate of 8.500% per annum and is payable semi-annually in arrears on June 15 and December 15, with the next interest payment being due on June 15, 2013. Any interest on overdue principal and interest will accrue at a rate that is 1% higher than the then applicable interest rate on the notes. W&T will make each interest payment to the holders of record on the immediately preceding June 1 and December 1.

Interest on the new notes will accrue from December 15, 2012, the date it was most recently paid on the old notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

If a holder of notes has given wire transfer instructions to W&T, W&T will pay all principal, interest and premium on that holder’s notes in accordance with those instructions. All other payments on the notes will be made at the office or agency of the paying agent and registrar within the City and State of New York unless W&T elects to make interest payments by check mailed to the holders at their addresses set forth in the register of holders.

Currently, the trustee acts as paying agent and registrar. W&T may change the paying agent or registrar without prior notice to the holders of the notes, and W&T or any of its Subsidiaries may act as paying agent or registrar.

A holder may transfer or exchange notes in accordance with the provisions of the indenture. The registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. Holders will be required to pay all taxes due on transfer. W&T will not be required to transfer or exchange any note selected for redemption. Also, W&T will not be required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed.

Like the old notes and the existing registered notes, the new notes will be jointly and severally guaranteed on a senior basis by the Guarantors. Any Domestic Subsidiaries of W&T that has Indebtedness outstanding in excess of a Minimum Amount or guarantees other Indebtedness of W&T or of a Guarantor in excess of a Minimum Amount will be required to guarantee the notes as set forth below under the caption described under “—Certain Covenants—Additional Note Guarantees.” The obligations of each Guarantor under its Note Guarantee are limited as necessary to prevent that Note Guarantee from constituting a fraudulent conveyance under applicable law. See “Risk Factors—Risks Relating to the Notes—If the subsidiary guarantees are deemed fraudulent conveyances or preferential transfers, a court may subordinate or void them.”

A Guarantor may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than W&T or another Guarantor, unless:

(1) immediately after giving effect to that transaction, no Default or Event of Default exists; and

(a) the Person acquiring the assets in any such sale or disposition or the Person formed by or surviving any such consolidation or merger (if other than W&T or another Guarantor) unconditionally assumes, pursuant to a supplemental indenture substantially in the form attached as an exhibit to the indenture, all the obligations of such Guarantor under the indenture and its Note Guarantee; or

(b) such transaction complies with the provisions of the indenture described under the caption “—Repurchase at the Option of Holders—Asset Sales.”

(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) to a Person that is not (either before or after giving effect to such transaction) W&T or a Restricted Subsidiary of W&T, if the sale or other disposition does not violate the “Asset Sales” provisions of the indenture;

(2) in connection with any sale or other disposition of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) W&T or a Restricted Subsidiary of W&T, if the sale or other disposition does not violate the “Asset Sales” provisions of the indenture and the Guarantor ceases to be a Subsidiary of W&T as a result of such sales or disposition;

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

(4) upon Legal Defeasance or Covenant Defeasance as described below under the caption “—Legal Defeasance and Covenant Defeasance” or upon satisfaction and discharge of the indenture as described below under the caption “—Satisfaction and Discharge”;

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

(6) at such time as such Guarantor is no longer required to be a Guarantor of the notes as described below under the caption “Certain Covenants—Additional Note Guarantees,” provided no Default or Event of Default has occurred and is continuing.

Except as otherwise described in this section and in the final paragraph under “—Repurchase at the Option of Holders—Change of Control,” the notes are not redeemable at W&T’s option prior to June 15, 2015. W&T is not, however, prohibited from acquiring the notes by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of the indenture.

On or after June 15, 2015, the notes will be subject to redemption at the option of W&T, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon to, but not including, the applicable redemption date (subject to the right of holders 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 June 15 of the year indicated below:

Prior to June 15, 2014, W&T may on any one or more occasions redeem up to 35% of the aggregate principal amount of notes at a redemption price of 108.500% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the redemption date (subject to the right of holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date) with the net cash proceeds of one or more Equity Offerings; provided that

(1) at least 65% in aggregate principal amount of notes originally issued under the indenture remains outstanding immediately after the occurrence of such redemption; and

(2) each such redemption must occur within 90 days of the date of the closing of the related Equity Offering.

In addition, at any time prior to June 15, 2015, the notes may be redeemed in whole or in part at the option of W&T at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption (subject to the right of holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

All redemptions of the notes will be made upon not less than 30 days’ nor more than 60 days’ prior notice, except that a redemption notice may be made 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 not be conditional, except that any redemption effected with the net proceeds of one more Equity Offerings as described above may, at W&T’s discretion, be conditioned upon completion of the related Equity Offering. Unless W&T defaults in the payment of the redemption price, interest will cease to accrue on the notes or portions thereof called for redemption on the applicable redemption date.

W&T is not required to make mandatory redemption or sinking fund payments with respect to the notes.

If less than all of the notes are to be redeemed at any time, the trustee will select notes for redemption on a pro rata basis (except that any notes represented by a global note will be redeemed by such method as DTC may require), unless otherwise required by law or applicable stock exchange requirements.

No notes of $1,000 or less can be redeemed in part. Notices of redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the indenture.

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the holder of notes upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of notes called for redemption, unless W&T defaults in making the payment of funds for such a redemption.

If a Change of Control occurs, each holder of notes will have the right to require W&T to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that holder’s notes pursuant to an offer (a “Change of Control Offer”) on the terms set forth in the indenture. In the Change of Control Offer, W&T will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest on the notes repurchased (subject to the right of holders of notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Change of Control Payment Date) to, but excluding, the date of purchase (the “Change of Control Payment Date”). Within 30 days following any Change of Control, W&T will mail a notice to each holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase notes properly tendered prior to the expiration date of the Change of Control Offer specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the indenture and described in such notice. W&T will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the indenture, W&T will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the indenture by virtue of such compliance.

Promptly following the expiration of the Change of Control Offer, W&T will, to the extent lawful, accept for payment all notes or portions thereof properly tendered pursuant to the Change of Control Offer, and W&T will:

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

(2) on the Change of Control Payment Date, deliver or cause to be delivered to the trustee the notes properly accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being purchased by W&T.

On the Change of Control Payment Date, the paying agent will mail to each holder of notes properly tendered the Change of Control Payment for such notes and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased

portion of the notes surrendered, if any; provided that each such new note will be in a principal amount of $1,000 or an integral multiple thereof. Any note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date unless W&T defaults in making the Change of Control Payment. W&T will publicly announce 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 W&T to make a Change of Control Offer following a Change of Control will be applicable 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 W&T repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

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

A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. Notes repurchased by W&T pursuant to a Change of Control Offer will have the status of notes issued but not outstanding or will be retired and cancelled, at W&T’s option. Notes purchased by a third party pursuant to the preceding paragraph will have the status of notes issued and outstanding.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties and assets of W&T 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 W&T to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the properties and assets of W&T and its Subsidiaries taken as a whole to another Person or group may be uncertain.

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

W&T will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) W&T (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the Equity Interests or other assets issued or sold or otherwise disposed of; and

(2) (a) at least 75% of the consideration received in the Asset Sale by W&T or such Restricted Subsidiary is in the form of cash or (b) the Fair Market Value of all forms of consideration other than cash received for all Asset Sales since the Issue Date does not exceed in the aggregate 10% of the Adjusted Consolidated Net Tangible Assets of W&T at the time each determination is made. For purposes of this provision, each of the following will be deemed to be cash:

(i) any liabilities, as shown on W&T’s most recent consolidated balance sheet, of W&T or any Restricted Subsidiary (other than contingent liabilities and Subordinated Obligations) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases W&T or such Restricted Subsidiary from further liability;

(ii) any securities, notes or other obligations received by W&T or any such Restricted Subsidiary from such transferee that are converted by W&T or such Restricted Subsidiary into cash within 180 days after the date of the Asset Sale, to the extent of the cash received in that conversion;

(iii) any stock or assets of the kind referred to in clauses (2) or (3) of the next paragraph of this covenant; and

(iv) accounts receivable of a business retained by W&T or any Restricted Subsidiary, as the case may be, following the sale of such business; provided that such accounts receivable are not (a) past due more than 90 days and (b) do not have a payment date greater than 120 days from the date of the invoice creating such accounts receivable.

Within 360 days after the receipt of any Net Proceeds from an Asset Sale, or, if W&T has entered into a binding commitment or commitments with respect to the actions described in clauses (2) or (3) below, within 540 days after the receipt of any Net Proceeds from an Asset Sale. W&T (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

(3) to make capital expenditures in respect of W&T’s or its Restricted Subsidiaries’ Oil and Gas Business; or

Pending the application of any Net Proceeds in the manner provided above, W&T or any Restricted Subsidiary may invest the Net Proceeds in any manner that is not prohibited by the indenture.

Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second paragraph of this covenant will constitute “Excess Proceeds.” Within five days after the date that the aggregate amount of Excess Proceeds exceeds $20.0 million, W&T will make an offer (an “Asset Sale Offer”) to all holders of notes and all holders of other Indebtedness that is pari passu 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 on a pro rata basis the maximum principal amount of notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest to, but excluding, the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, W&T may use those Excess Proceeds for any purpose not otherwise prohibited by the indenture. If the aggregate principal amount of notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds allocated for the purchase of notes pursuant to the Asset Sale Offer, the trustee will select the notes to be purchased on a pro rata basis (or, in the case of notes represented by a global note, the trustee will select notes for purchase by such method as DTC may require). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

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

The Credit Agreement and certain other agreements governing W&T’s other Indebtedness contain, and future agreements may contain, prohibitions of certain events, including events that would constitute a Change of Control or an Asset Sale and including repurchases of or other prepayments in respect of the notes. The exercise by the holders of notes of their right to require W&T to repurchase the notes upon a Change of Control or an Asset Sale could cause a default under these other agreements, even if the Change of Control or Asset Sale itself is not due to the financial effect of such repurchases on W&T or otherwise. In the event a Change of Control or Asset Sale occurs at a time when W&T is prohibited from purchasing notes, W&T could seek the consent of the applicable lenders to the purchase of notes or could attempt to refinance the Indebtedness that contain such prohibitions. If W&T does not obtain a consent or repay that Indebtedness, W&T will remain prohibited from purchasing notes. In that case, W&T’s failure to purchase tendered notes would constitute an Event of Default under the indenture which could, in turn, constitute a default under other Indebtedness. Finally, W&T’s ability to pay cash to the holders of notes upon a repurchase may be limited by W&T’s then existing financial resources. See “Risk factors—Risks Relating to the Notes—We may not be able to repurchase the notes upon a change of control.”

W&T will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of W&T’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any dividend, payment or distribution made by W&T or any of its Restricted Subsidiaries in connection with any merger or consolidation involving W&T or any of its Restricted Subsidiaries) or to the direct or indirect holders of W&T’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 W&T and other than dividends or distributions payable to W&T or a Restricted Subsidiary of W&T);

(2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, any such purchase, redemption, acquisition or retirement made in connection with any merger or consolidation involving W&T) any Equity Interests of W&T or any direct or indirect parent of W&T;

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, prior to the Stated Maturity thereof, any Subordinated Obligation (excluding the purchase or other acquisition of any Subordinated Obligation in anticipation of satisfying a sinking fund obligation, principal installment or final maturity payment, in each case due within one year of the date of purchase or other acquisition); or

(all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as “Restricted Payments”),

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;

(2) W&T 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 Issuance of Preferred Stock;” and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by W&T and its Restricted Subsidiaries since the Prior Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (9) or (10) of the next succeeding paragraph), is equal to or less than the sum, without duplication, of the following (such sum being referred to as the “Restricted Payments Basket”):

(a) 50% of the Consolidated Net Income of W&T for the period (taken as one accounting period) from April 1, 2007 to the end of W&T’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 received that is used or useful in the Oil and Gas Business by W&T since the Prior Issue Date from the sale of Equity Interests of W&T (other than Disqualified Stock) or as a contribution to W&T’s common equity capital or from the sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of W&T that have been converted or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of W&T or to an employee stock ownership plan, option plan or similar trust to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or guaranteed by W&T or any of its Restricted Subsidiaries unless such loans have been repaid with cash on or prior to the date of determination); plus

(c) the amount equal to the net reduction in Restricted Investments made by W&T or any of its Restricted Subsidiaries in any Person since the Prior Issue Date resulting from:

(i) repurchases or redemptions of such Restricted Investments by such Person, proceeds realized upon the sale of such Restricted Investment to a purchaser other than W&T or a Subsidiary or W&T, repayments of loans or advances or other transfers of assets (including by way of dividend or distribution) by such Person to W&T or any Restricted Subsidiary of W&T; or

(ii) the redesignation of any Unrestricted Subsidiary as a Restricted Subsidiary (valued in each case at the Fair Market Value of W&T’s Investment in such Unrestricted Subsidiary at the time of redesignation) not to exceed the amount of Investments previously made by W&T or any Restricted Subsidiary of W&T in such Unrestricted Subsidiary,

which amount in each case under this clause (c) was included in the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this clause (c) to the extent it is already included in Consolidated Net Income; plus

(d) 50% of any dividends received by W&T or a Restricted Subsidiary of W&T that is a Guarantor after the Prior Issue Date from an Unrestricted Subsidiary of W&T, to the extent that such dividends were not otherwise included in the Consolidated Net Income of W&T for such period.

(1) the payment of any dividend within 90 days after the date of declaration of the dividend or the consummation of any irrevocable redemption within 60 days after the date of giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of the indenture;

(2) the making of any Restricted Payment since the Issue Date in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of W&T) of, Equity Interests of W&T (other than Disqualified Stock and other than Equity Interests issued or sold to an employee stock ownership plan, option plan or similar trust to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or guaranteed by W&T or any of its Restricted Subsidiaries unless such loans have been repaid with cash on or prior to the date of determination) or from the substantially concurrent contribution of common equity capital to W&T; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (3)(b) of the preceding paragraph;

(3) the repurchase, redemption, defeasance or other acquisition or retirement for value since the Issue Date of Subordinated Obligations in exchange for, or with the net cash proceeds from a substantially concurrent incurrence of, Permitted Refinancing Indebtedness;

(4) the payment since the Issue Date of any dividend (or, in the case of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary of W&T to the holders of its Equity Interests on a pro rata basis;

(5) so long as no Default has occurred and is continuing or would be caused thereby, the repurchase, redemption or other acquisition or retirement for value since the Prior Issue Date of any Equity Interests of W&T or any Restricted Subsidiary of W&T held by any of W&T’s (or any of its Restricted Subsidiaries’) current or former directors or employees pursuant to any director or employee equity subscription agreement, stock option agreement or restricted stock agreement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $5.0 million in any twelve-month period (with unused amounts in any 12-month period being permitted to be carried over into succeeding 12-month periods); provided, further, that the amounts in any 12-month period may be increased by an amount not to exceed (A) the cash proceeds received by W&T or any of its Restricted Subsidiaries from the sale of W&T’s Equity Interests (other than Disqualified Stock) to any such directors or employees that occurs after the Prior Issue Date (provided that the amount of such cash proceeds utilized for any such repurchase, retirement or other acquisition or retirement will be excluded from clause (3)(b) of the preceding paragraph) plus (B) the cash proceeds of key man life insurance policies received by W&T and its Restricted Subsidiaries after the Prior Issue Date;

(6) so long as no Default has occurred and is continuing or would be caused thereby, the repurchase, redemption or other acquisition or retirement for value since the Issue Date of any Equity Interests of W&T or any Restricted Subsidiary of W&T held by any of W&T’s (or any of its Restricted Subsidiaries’) current or former directors or employees in connection with the exercise or vesting of any equity compensation (including, without limitation, stock options, restricted stock and phantom stock) or made in order to satisfy W&T’s or such Restricted Subsidiary’s tax withholding obligation with respect to such exercise or vesting;

(7) so long as no Default has occurred and is continuing or would be caused thereby, repurchases of Subordinated Obligations at a purchase price not greater than (i) 101% of the principal amount of such Subordinated Obligations in the event of a Change of Control or (ii) 100% of the principal amount of such Subordinated Obligations in the event of an Asset Sale, in each case plus accrued and unpaid interest, in connection with any change of control offer or asset sale offer required by the terms of such Subordinated Obligations, but only if:

(a) in the case of a Change of Control, W&T has first complied with and fully satisfied its obligations under the provisions described under “—Repurchase at the Option of Holders—Change of Control” (including without limitation the repurchase of all notes validly tendered for payment in connection therewith); or

(b) in the case of an Asset Sale, W&T has complied with and fully satisfied its obligations in accordance with the covenant under the heading, “—Repurchase at the Option of Holders—Asset Sales” (including without limitation the repurchase of all notes validly tendered for payment in connection therewith);

(8) the repurchase, redemption or other acquisition or retirement for value of Capital Stock of W&T representing fractional shares of such Capital Stock in connection with a merger, consolidation or other combination involving W&T or any other transaction permitted by the indenture;

(9) Restricted Payments of the type referred to in clauses (1) or (2) of the first paragraph of this covenant in an amount up to $30.0 million for each twelve-month period following the Prior Issue Date, with any unused portion of such amount in any such period to be carried forward to succeeding twelve-month periods;

(10) other Restricted Payments in an aggregate amount not to exceed $200.0 million since the Prior Issue Date; and

(11) the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of W&T or any Restricted Subsidiary of W&T issued on or after the Prior Issue Date in accordance with the Fixed Charge Coverage Ratio test described below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock.”

The amount of all Restricted Payments (other than cash) will 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 W&T or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued by this covenant will be evidenced by an officers’ certificate delivered to the trustee within five Business Days of the making of the Restricted Payment, together with a copy of any related resolution of the Board of Directors of W&T. Such officers’ certificate shall state that the Restricted Payment is permitted by this covenant. For purposes of determining compliance with this covenant, in the event that a Restricted Payment meets the criteria of more than one of the exceptions described in (1) through (11) above or is entitled to be made pursuant to the first paragraph of this covenant, W&T shall, in its sole discretion, classify such Restricted Payment, or later classify, reclassify or re-divide all or a portion of such Restricted Payment, in any manner that complies with this covenant.

W&T 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), and W&T will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that W&T and the Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or preferred stock of a Restricted Subsidiary, if the Fixed Charge Coverage Ratio for W&T’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock of a Restricted Subsidiary is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or preferred stock of a Restricted Subsidiary had been issued, as the case may be, 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 Debt”):

(1) the incurrence by W&T and any Restricted Subsidiary of Indebtedness (including letters of credit) under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of W&T and its Restricted Subsidiaries thereunder) not to exceed the greater of (a) $800.0 million and (b) an amount equal to the sum of (A) $600.0 million plus (B) 10% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom;

(2) the incurrence by W&T and its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by W&T and the Guarantors of Indebtedness represented by the existing registered notes and the related Note Guarantees and any exchange notes and related guarantees issued in exchange therefor pursuant to a registration rights agreement;

(4) the incurrence by W&T or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of W&T or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $50.0 million at any time outstanding;

(5) the incurrence by W&T or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any 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) or (11) of this paragraph or this clause (5);

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

(a) if W&T or any Guarantor is the obligor on such Indebtedness and the payee is not W&T or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the notes, in the case of W&T, or the Note Guarantee, in the case of a Guarantor; and

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than W&T or a Restricted Subsidiary of W&T and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either W&T or a Restricted Subsidiary of W&T will be deemed, in each case, to constitute an incurrence of such Indebtedness by W&T or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the issuance by any of W&T’s Restricted Subsidiaries to W&T or to any of its Restricted Subsidiaries of shares of preferred stock; provided, however, that:

(a) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than W&T or a Restricted Subsidiary of W&T; and

(b) any sale or other transfer of any such preferred stock to a Person that is not either W&T or a Restricted Subsidiary of W&T, will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (7);

(8) the incurrence by W&T or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business;

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

(10) the Guarantee by W&T or any of the Guarantors of Indebtedness of W&T or a Restricted Subsidiary of W&T that was permitted to be incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the notes, then the Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed;

(12) the incurrence by W&T or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days;

(13) Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of W&T and its Restricted Subsidiaries;

(14) the incurrence by W&T or any of its Restricted Subsidiaries of Indebtedness arising from agreements of W&T or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by W&T and its Restricted Subsidiaries in connection with such disposition;

(15) the incurrence by W&T or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance, surety and similar bonds issued for the account of W&T and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of W&T or any of its Restricted Subsidiaries with respect to letters of credit supporting such obligations (in each case, other than an obligation for money borrowed); and

(16) the incurrence by W&T or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding not to exceed $100.0 million

W&T will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of W&T or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis.

For purposes of determining compliance with this “Incurrence of Indebtedness and Issuance of Preferred Stock” covenant, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, W&T will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant. The accrual of interest, 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, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of W&T as accrued. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that W&T or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

W&T will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien (other than Permitted Liens) upon any of its property or assets (whether now owned or hereafter acquired), securing any Subordinated Obligations or other Indebtedness, unless:

(1) in the case of any Lien securing Subordinated Obligations of W&T or a Guarantor, the notes or Note Guarantee, as applicable, are secured by a Lien on such property or assets on a senior basis to the Subordinated Obligations so secured until such time as such Subordinated Obligations are no longer so secured by that Lien; and

(2) in the case of any other Lien (other than a Permitted Lien) securing other Indebtedness, the notes or Note Guarantees, as applicable, are secured by a Lien on such property or assets on an equal and ratable basis with the Indebtedness so secured until such time as such Indebtedness is no longer so secured by that Lien.

W&T 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:

(1) pay dividends or make any other distributions on its Capital Stock to W&T or any of its Restricted Subsidiaries, or pay any indebtedness owed to W&T or any of its Restricted Subsidiaries;

(3) sell, lease or transfer any of its properties or assets to W&T or any of its Restricted Subsidiaries.

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

(1) agreements governing Existing Indebtedness and Credit Facilities as in effect on the Issue Date and any amendments, restatements, modifications, renewals, supplements, increases, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, increases, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment encumbrances or restrictions than those contained in those agreements on the Issue Date;

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

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by W&T or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock 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;

(5) customary non-assignment provisions in contracts, leases and licenses (including, without limitation, licenses of intellectual property) entered into in the ordinary course of business;

(6) purchase money obligations for property (including Capital Stock) acquired in the ordinary course of business, Capital Lease Obligations and mortgage financings that impose restrictions on the property purchased or leased of the nature described in clause (3) of the preceding paragraph;

(7) any agreement for the sale or other disposition of assets, including without limitation an agreement for the sale or other disposition of the Capital Stock or assets of a Restricted Subsidiary that restricts distributions by the applicable Restricted Subsidiary pending the sale or other disposition;

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

(9) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into (a) in the ordinary course of business consistent with past practice or (b) with the approval of W&T’s Board of Directors, which limitations are applicable only to the assets or property that are the subject of such agreements;

(10) other Indebtedness of W&T or any of its Restricted Subsidiaries permitted to be incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with the covenant described under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”; provided that the provisions of such agreement relating to such dividend and other payment encumbrances or restrictions taken as a whole are not materially more restrictive, as determined by the Board of Directors or W&T in good faith, than those provisions contained in the agreements governing Existing Indebtedness and the Credit Agreement, in each case as in effect on the Issue Date;

(11) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred stock was made in accordance with the covenant described under the caption “—Incurrence of Indebtedness and Incurrence of Preferred Stock” and the terms of such preferred stock do not expressly restrict the ability of a Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital Stock);

(12) supermajority voting requirements existing under corporate charters, bylaws, stockholders’ agreements and similar documents and agreements;

(14) encumbrances or restrictions contained in Hedging Obligations permitted from time to time under the indenture; and

(15) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business.

W&T will not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not W&T is the surviving corporation), or (2) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties and assets, in one or more related transactions, to another Person, unless:

(1) either: (a) W&T is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than W&T) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

(2) the Person formed by or surviving any such consolidation or merger (if other than W&T) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of W&T under the notes and the indenture pursuant to agreements reasonably satisfactory to the trustee; provided that, unless such Person is a corporation, a corporate co-issuer of the notes will be added to the indenture by agreements reasonably satisfactory to the trustee;

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

(4) W&T or the Person formed by or surviving any such consolidation or merger (if other than W&T), or to which such sale, assignment, transfer, conveyance or other disposition has been made, 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 “—Incurrence of Indebtedness and Issuance of Preferred Stock” or would have a Fixed Charge Coverage Ratio not less than the Fixed Charge Coverage Ratio of W&T immediately prior to such transaction.

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of W&T, which properties and assets, if held by W&T instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of W&T on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of W&T.

The surviving entity will succeed to, and be substituted for, and may exercise every right and power of, W&T under the indenture, but, in the case of a lease of all or substantially all of its assets, W&T will not be released from the obligation to pay the principal of and interest and premium, if any, on the notes.

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 property and assets of a Person.

Notwithstanding the restrictions described in the foregoing clause (4), any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to W&T, W&T may merge into a Restricted Subsidiary for the purpose of reincorporating W&T in another jurisdiction, and any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to another Restricted Subsidiary.

W&T 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 of W&T (each, an “Affiliate Transaction”), unless:

(1) the Affiliate Transaction is on terms that are no less favorable to W&T or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by W&T or such Restricted Subsidiary with an unrelated Person; and

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an officers’ certificate certifying that such Affiliate Transaction complies with this covenant; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $40.0 million, a resolution of the Board of Directors of W&T set forth in an officers’ certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of W&T.

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

(1) any employment agreement or arrangement, stock option or stock ownership plan, employee benefit plan, officer or director indemnification agreement, restricted stock agreement, severance agreement or other compensation plan or arrangement entered into by W&T or any of its Restricted Subsidiaries in the ordinary course of business and payments, awards, grants or issuances of securities pursuant thereto, including, without limitation, pursuant to W&T’s Long-Term Incentive Compensation Plan, as amended;

(3) transactions with a Person (other than an Unrestricted Subsidiary of W&T) that is an Affiliate of W&T solely because W&T owns, directly or through a Restricted Subsidiary, an Equity Interest in such Person;

(4) reasonable fees and expenses and compensation paid to, and indemnity or insurance provided on behalf of, officers, directors or employees of W&T or any Restricted Subsidiaries as determined in good faith by the Board of Directors;

(5) any issuance of Equity Interests (other than Disqualified Stock) of W&T to, or receipt by W&T of a capital contribution from, Affiliates (or a Person that becomes an Affiliate) of W&T;

(6) Restricted Payments that do not violate the provisions of the indenture described above under the caption “—Restricted Payments”;

(7) transactions between W&T or any Restricted Subsidiaries and any Person, a director of which is also a director of W&T or any direct or indirect parent company of W&T and such director is the sole cause for such Person to be deemed an Affiliate of W&T or any Restricted Subsidiaries; provided, however, that such director abstains from voting as director of W&T or such direct or indirect parent company, as the case may be, on any matter involving such other Person;

(8) loans or advances to employees in the ordinary course of business or consistent with past practice not to exceed $5.0 million in the aggregate at any one time outstanding;

(9) advances to or reimbursements of employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the ordinary course of business;

(10) any transaction in which W&T 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 is fair to W&T or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (1) of the preceding paragraph;

(11) the performance of obligations of W&T or any of its Restricted Subsidiaries under the terms of any written agreement to which W&T or any of its Restricted Subsidiaries is a party on the Issue Date and which is described in this offering memorandum, as these agreements may be amended, modified or supplemented from time to time; provided, however, that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its terms do not materially and adversely affect the rights of any holders of the notes (as determined in good faith by the Board of Directors of W&T) as compared to the terms of the agreements in effect on the Issue Date; and

(12) (a) guarantees of performance by W&T and its Restricted Subsidiaries of W&T’s Unrestricted Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money, and (b) pledges of Equity Interests of W&T’s Unrestricted Subsidiaries for the benefit of lenders of W&T’s Unrestricted Subsidiaries.

If, after the Issue Date, any Domestic Subsidiary that is not already a Guarantor has Indebtedness outstanding in excess of a Minimum Amount or guarantees any other Indebtedness of W&T or of a Guarantor in

excess of a Minimum Amount, then such Domestic Subsidiary will become a Guarantor with respect to the notes by executing and delivering a supplemental indenture, in the form attached as an exhibit to the indenture, to the trustee within 180 days of the date on which it guaranteed such Indebtedness.

The Board of Directors of W&T may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by W&T and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the covenant described above under the caption “—Restricted Payments” or under one or more clauses of the definition of Permitted Investments, as determined by W&T. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Any designation of a Subsidiary of W&T as an Unrestricted Subsidiary will be evidenced to the trustee by filing with the trustee a certified copy of a resolution of the Board of Directors of W&T giving effect to such designation and an officer’s certificate certifying that such designation complied with the preceding conditions and was permitted by the covenant described above under the caption “—Restricted Payments.” If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of the indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of W&T as of such date and, if such Indebtedness is not permitted to be incurred as of such date under the covenant described under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock,” W&T will be in default of such covenant. The Board of Directors of W&T may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of W&T; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of W&T of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under the covenant described under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock,” calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period and (2) no Default or Event of Default would be in existence immediately following such designation.

So long as any notes are outstanding, W&T will file with the SEC for public availability, within 30 days of the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing, in which case W&T will furnish to the holders of notes or cause the trustee to furnish to the holders of notes, within the time periods specified in the SEC’s rules and regulations):

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if W&T were required to file such reports; and

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

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will include an audit report on W&T’s consolidated financial statements by a nationally recognized firm of independent accountants. W&T will conduct a conference call for holders of the notes, any prospective investor and any security analyst to discuss the information furnished pursuant to the previous paragraph no later than three business days after furnishing any information pursuant to clause (1) of the previous paragraph.

If, at any time, W&T is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, W&T will nevertheless continue filing the reports specified in the preceding paragraphs of this covenant with the SEC within the time periods specified above unless the SEC will not accept such a filing. W&T will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept W&T’s filings for any reason, W&T will post the reports referred to in the preceding paragraphs on its website within 30 days of the time periods that would apply if W&T were required to file those reports with the SEC.

If W&T has designated any of its Subsidiaries as Unrestricted Subsidiaries, then, to the extent material as determined by the Board of Directors of W&T in good faith, the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of W&T and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of W&T.

In addition, W&T and the Guarantors agree that, for so long as any old notes remain outstanding, if at any time they are not required to file the reports required by the preceding paragraphs with the SEC, they will furnish to the holders of old notes and to securities analysts and prospective investors in the old notes, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

If on any date following the Issue Date, (1) the notes are assigned an Investment Grade Rating from both Rating Agencies and (2) no Default or Event of Default shall have occurred and be continuing, then W&T and its Restricted Subsidiaries will no longer be subject to the following provisions of the indenture:

Following the termination of the foregoing covenants, W&T’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the covenant described below under the caption “—Designation of Restricted and Unrestricted Subsidiaries” or the second paragraph of the definition of “Unrestricted Subsidiary.”

There can be no assurance that the notes will achieve or maintain an Investment Grade Rating.

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

(3) failure by W&T or any of its Restricted Subsidiaries to comply with the provisions described under the captions “—Repurchase at the Option of Holders—Change of Control,” “—Repurchase at the Option of Holders—Asset Sales,” or “—Certain Covenants—Merger, Consolidation or Sale of Assets”;

(4) failure by W&T or any of its Restricted Subsidiaries for 60 days after notice to W&T by the trustee or the holders of at least 25% in aggregate principal amount of the notes then outstanding voting as a single class to comply with any of the other agreements in the indenture;

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

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

(b) results in the acceleration of such Indebtedness prior to its express 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 $20.0 million or more; provided that if any such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 15 Business Days from the continuation of such 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;

(6) failure by W&T or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $20.0 million (net of any amount with respect to which a reputable and solvent insurance company has acknowledged liability in writing), which judgments are not paid, discharged, stayed or fully bonded for a period of 60 days (or, if later, the date when payment is due pursuant to such judgment);

(7) (a) except as permitted by the indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or (b) any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; and

(8) certain events of bankruptcy or insolvency described in the indenture with respect to W&T or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary.

In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to W&T, any Restricted Subsidiary of W&T that is a Significant Subsidiary or any group of Restricted Subsidiaries of W&T 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 aggregate principal amount of the then outstanding notes may declare all of the notes to be due and payable immediately by notice in writing to W&T and, in the case of a notice by holders, also to the trustee specifying the applicable Events of Default and that it is a notice of acceleration.

Subject to certain limitations, holders of a majority in aggregate 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 if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest or premium, if any.

Subject to the provisions of the indenture relating to the duties of the trustee in case an Event of Default occurs and is continuing, the trustee is under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any holders of notes unless such holders have offered to the trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no holder of a note may pursue any remedy with respect to the indenture or the notes unless:

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

(2) holders of at least 25% in aggregate principal amount of the then outstanding notes have requested the trustee to pursue the remedy;

(3) such holders have offered the trustee reasonable indemnity against any loss, liability or expense;

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

(5) holders of a majority in aggregate principal amount of the then outstanding notes have not given the trustee a direction inconsistent with such request within such 60-day period.

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, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the indenture except a continuing Default or Event of Default in the payment of interest or premium on, or the principal of, the notes.

W&T and the Guarantors are required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default or Event of Default, W&T and the Guarantors are required within five days to deliver to the trustee a statement specifying such Default or Event of Default.

No director, officer, employee, incorporator, member, partner or stockholder of W&T or any Guarantor, as such, has any liability for any obligations of W&T or the Guarantors under the notes, the indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

W&T may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an officers’ certificate, elect to have all of its obligations discharged with respect to the outstanding notes and all obligations of the Guarantors discharged with respect to their Note Guarantees (“Legal Defeasance”) except for:

(1) the rights of holders of outstanding notes to receive payments in respect of the principal of, or interest or premium on, such notes when such payments are due from the trust referred to below;

(2) W&T’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 W&T’s and the Guarantors’ obligations in connection therewith; and

In addition, W&T may, at its option and at any time, elect to have the obligations of W&T and the Guarantors released with respect to certain covenants (including its obligation to make Change of Control Offers and Asset Sale Offers) that are described in the indenture (“Covenant Defeasance”) and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under “—Events of Default and Remedies” will no longer constitute an Event of Default with respect to the notes. If W&T exercises either its Legal Defeasance or Covenant Defeasance option, each Guarantor will be released and relieved of any obligations under its Note Guarantee and any security for the notes (other than the trust) will be released.

(1) W&T 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 of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, or interest and premium on, the outstanding notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and W&T must specify whether the notes are being defeased to such stated date for payment or to a particular redemption date;

(2) in the case of Legal Defeasance, W&T must deliver to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that (a) W&T has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of the indenture, 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 will 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, W&T must deliver 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;

(4) no Default or Event of Default has occurred and is 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) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which W&T or any Guarantor is a party or by which W&T or any Guarantor is bound;

(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) to which W&T or any of its Subsidiaries is a party or by which W&T or any of its Subsidiaries is bound;

(6) W&T must deliver to the trustee an officers’ certificate stating that the deposit was not made by W&T with the intent of preferring the holders of notes over the other creditors of W&T with the intent of defeating, hindering, delaying or defrauding any creditors of W&T or others; and

(7) W&T must deliver to the trustee an officers’ certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Except as provided in the next two succeeding paragraphs, the indenture, the notes or the Note Guarantees may be amended or supplemented with the consent of the holders of at least a majority in aggregate principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or

tender offer or exchange offer for, notes), and any existing Default or Event of Default or compliance with any provision of the indenture or the notes or the Note Guarantees may be waived with the consent of the holders of a majority in aggregate principal amount of the then outstanding notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes).

Without the consent of each holder of notes 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 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”);

(3) reduce the rate of or change the time for payment of interest, including default interest, on any note;

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium on, the notes (except a rescission of acceleration of the notes by the holders of a majority in aggregate principal amount of the then outstanding notes and a waiver of the payment default that resulted from such acceleration);

(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 interest or premium on, the notes;

(7) waive a redemption payment with respect to any note (other than a payment required by one of the covenants described above under the caption “—Repurchase at the Option of Holders”);

(8) release any Guarantor from any of its obligations under its Note Guarantee or the indenture, except in accordance with the terms of the indenture; or

Notwithstanding the preceding, without the consent of any holder of notes, W&T, the Guarantors and the trustee may amend or supplement the indenture, the notes or the Note Guarantees:

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

(3) to provide for the assumption of W&T’s or a Guarantor’s obligations to holders of notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of W&T’s or such Guarantor’s properties and assets, as applicable;

(4) to make any change that would provide any additional rights or benefits to the holders of notes or that does not adversely affect the legal rights under the indenture of any such holder;

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

(6) to conform the text of the indenture, the Note Guarantees or the notes to any provision of the “Description of Notes” section in W&T’s offering memorandum dated June 3, 2011 relating to the existing registered notes to the extent that such provision in such Description of Notes was intended to be a verbatim recitation of a provision of the indenture, the Note Guarantees or the notes;

(7) to provide for the issuance of additional notes in accordance with the limitations set forth in the indenture as of the date of the indenture;

(8) to allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the notes or release Note Guarantees pursuant to the terms of the indenture;

(10) to evidence and provide for the acceptance under the indenture of a successor trustee.

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

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

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

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

(2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposits), and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which W&T or any of its Subsidiaries is a party or by which W&T or any of its Subsidiaries is bound;

(3) W&T or any Guarantor has paid or caused to be paid all sums payable by it under the indenture; and

(4) W&T has delivered irrevocable instructions to the trustee under the indenture to apply the deposited money toward the payment of the notes at maturity or on the redemption date, as the case may be.

In addition, W&T must deliver an officers’ certificate and an opinion of counsel to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

If the trustee becomes a creditor of W&T or any Guarantor, the indenture limits the right of the trustee 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 is permitted to engage in other transactions; however, if it acquires any conflicting interest (as defined in the Trust Indenture Act), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (if the indenture has been qualified under the Trust Indenture Act) or resign.

The holders of a majority in aggregate principal amount of the then outstanding notes have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that in case an Event of Default occurs and is continuing, the trustee is required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the trustee is 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 has offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense.

The new notes will be issued initially only in the form of one or more global notes (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). The Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for definitive notes in registered certificated form (“Certificated Notes”) except in the limited circumstances described below. Please read “— Exchange of Global Notes for Certificated Notes.”

In addition, transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear and Clearstream), which may change from time to time.

The following description of the operations and procedures of DTC, Euroclear and Clearstream (as indirect participants in DTC) are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. W&T takes no responsibility for these operations and procedures and urges investors to contact the system or their participants directly to discuss these matters.

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

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

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

Investors in the Global Notes who are Participants may hold their interests therein directly through DTC. Investors in the Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems. The laws of some jurisdictions may require that certain Persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such Persons will be limited to that extent. Because DTC can act only on behalf of the Participants, which in turn act on behalf of the Indirect Participants, the ability of a Person having beneficial interests in a Global Note to pledge such interests to Persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

Except as described below, owners of interests in the Global Notes will not have notes registered in their names, will not receive physical delivery of notes in certificated form and will not be considered the registered owners or “holders” thereof under the indenture for any purpose.

Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee are payable to DTC in its capacity as the registered holder under the indenture. Under the terms of the indenture, W&T and the trustee will treat the Persons in whose names the notes, including the Global Notes, are registered as the owners of the notes for the purpose of receiving payments and for all other purposes. Consequently, neither W&T, the trustee, nor any agent of W&T or the trustee, has or will have any responsibility or liability for:

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

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

DTC has advised W&T that its current practice, upon receipt of any payment in respect of securities such as the notes (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe that it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustee or W&T. Neither W&T nor the trustee will be liable for any delay by DTC or any of the Participants or the Indirect Participants in identifying the beneficial owners of the notes, and W&T and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

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

Cross-market transfers between the Participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering

or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

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

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Rule 144A Global Notes and the Regulation S Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. None of W&T, the trustee and any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

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

(2) W&T, at its option, notifies the trustee in writing that it elects to cause the issuance of the Certificated Notes; or

(3) there has occurred and is continuing a Default or Event of Default with respect to the notes.

In addition, beneficial interests in a Global Note may be exchanged for Certificated Notes upon prior written notice given to the trustee by or on behalf of DTC in accordance with the indenture. In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Certificated Notes may not be exchanged for beneficial interests in any Global Note except in the limited circumstances provided in the Indenture.

W&T will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by DTC or its nominee. W&T will make all payments of principal, interest and premium, if any, with respect to Certificated Notes by wire transfer of immediately available funds to the accounts specified by the holders of the Certificated Notes or, if no such account is specified, by mailing a check to each such holder’s registered address. The notes represented by the Global Notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. W&T expects that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised W&T that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

(i) estimated proved crude oil and natural gas reserves of W&T and its Restricted Subsidiaries attributable to acquisitions consummated since the date of such reserve report, and

(ii) estimated crude oil and natural gas reserves of W&T and its Restricted Subsidiaries attributable to extensions, discoveries and other additions and upward determinations of estimates of proved crude oil and natural gas reserves (including previously estimated development costs incurred during the period and the accretion of discount since the prior period end) due to

(d) to the extent included in clause (1)(a) above, the discounted future net revenue calculated in accordance with SEC guidelines (utilizing the same prices utilized in W&T’s year-end reserve report), attributable to reserves that are required to be delivered to third parties to fully satisfy the obligations of W&T and its Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified with respect thereto; and

(e) the discounted future net revenue, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production included in determining the discounted future net revenue specified in the immediately preceding clause (i)(a) (utilizing the same prices utilized in W&T’s year-end reserve report), would be necessary to satisfy fully the obligations of W&T and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto.

If W&T changes its method of accounting from the full cost method to the successful efforts method or a similar method of accounting, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if W&T were still using the full cost method of accounting.

“Beneficial Owner “ has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time.

You may transfer new notes issued under the exchange offer in exchange for the old notes if:

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

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

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

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 new notes.

Any broker-dealer that resells new notes that were received by it for its own account pursuant to the exchange offer in exchange for old notes that were acquired by such broker-dealer as a result of market-making or other trading activities may be deemed to be an “underwriter” within the meaning of the Securities Act. The letter of transmittal states that by acknowledging that it will deliver 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. We agreed to permit the use of this prospectus for a period of up to 180 days after the completion of the exchange offer by such broker-dealers to satisfy this prospectus delivery requirement. Furthermore, we agreed to amend or supplement this prospectus during such period if so requested in order to expedite or facilitate the disposition of any new notes by broker-dealers.

We have agreed to pay all expenses incident to the exchange offer other than fees and expenses of counsel to the holders and brokerage commissions and transfer taxes, if any, and will indemnify the holders of the old notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

The following discussion is a summary of the material federal income tax considerations relevant to the exchange of old notes for new notes, but does not purport to be a complete analysis of all potential tax effects. The discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations, Internal Revenue Service rulings and pronouncements and judicial decisions now in effect, all of which may be subject to change at any time by legislative, judicial or administrative action. These changes may be applied retroactively in a manner that could adversely affect a holder of new notes. 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 his own tax advisor as to the particular tax consequences of exchanging such holder’s old notes for new notes, including the applicability and effect of any foreign, state, local or other tax laws or estate or gift tax considerations.

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

The validity of the new notes offered in this exchange offer will be passed upon for us by Vinson & Elkins L.L.P., Houston, Texas.

CITY TIME, ON , 2013 (THE “EXPIRATION DATE”), UNLESS THE EXCHANGE OFFER IS

If you wish to exchange your issued and outstanding 8.500% Senior Notes due 2019 (“old notes”) for an equal aggregate principal amount of newly issued 8.500% Senior Notes due 2019 (“new notes”) with materially identical terms that have been registered under the Securities Act of 1933, as amended (the “Securities Act”) pursuant to the exchange offer, you must validly tender (and not withdraw) your old notes to the Exchange Agent prior to the Expiration Date.

We refer you to the Prospectus, dated , 2013 (the “Prospectus”), of W&T Offshore, Inc.

Capitalized terms used but not defined herein have the respective meaning given to them in the Prospectus.

The Issuer reserves the right, at any time or from time to time, to extend the Exchange Offer at its discretion, in which event the term “Expiration Date” shall mean the latest date and time to which the Exchange Offer is extended. The Issuer shall notify the Exchange Agent and each registered holder of the old notes of any extension by oral or written notice prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

You may, if you are unable to make all of the representations and warranties contained in Item 5 above and as otherwise permitted in the Registration Rights Agreement (as defined below), elect to have your old notes registered in the shelf registration statement described in the Registration Rights Agreement, dated as of October 24, 2012 (the “Registration Rights Agreement”), by and among the Issuer, the Guarantors (as defined therein), and the Initial Purchasers (as defined therein). Such election may be made by notifying the Issuer in writing at Nine Greenway Plaza, Suite 300, Houston, Texas 77046, Attention: General Counsel.

If you are a broker-dealer that will receive new notes for your own account in exchange for old notes that were acquired as a result of market-making activities or other trading activities, you acknowledge by tendering old notes in the Exchange Offer, that you will deliver a prospectus in connection with any resale of such new notes; however, by so acknowledging and by delivering a prospectus, you will not be deemed to admit that you are an “underwriter” within the meaning of the Securities Act.

7. If you are a broker-dealer and old notes held for your own account were not acquired as a result of market-making or other trading activities, such old notes cannot be exchanged pursuant to the Exchange Offer.

8. Any of your obligations hereunder shall be binding upon your successors, assigns, executors, administrators, trustees in bankruptcy and legal and personal representatives.

Any confirmation of a book-entry transfer to the Exchange Agent’s account at DTC of old notes tendered by book-entry transfer (a “Book-Entry Confirmation”), as well as Agent’s Message and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent at its address set forth herein prior to the Expiration Date.

Tenders of old notes will be accepted only in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof. The entire principal amount of old notes delivered to the Exchange Agent will be deemed to have been tendered unless otherwise communicated to the Exchange Agent. If the entire principal amount of all old notes is not tendered, then old notes for the principal amount of old notes not tendered and new notes issued in exchange for any old notes accepted will be delivered to the holder via the facilities of DTC promptly after the old notes are accepted for exchange.

All questions as to the validity, form, eligibility (including time of receipt), acceptance, and withdrawal of tendered old notes will be determined by the Issuer, in its sole discretion, which determination will be final and binding. The Issuer reserves the absolute right to reject any or all tenders not in proper form or the acceptance for exchange of which may, in the opinion of counsel for the Issuer, be unlawful. The Issuer also reserves the absolute right to waive any of the conditions of the Exchange Offer or any defect or irregularity in the tender of any old notes. The Issuer’s interpretation of the terms and conditions of the Exchange Offer (including the instructions on the Letter of Transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of old notes must be cured within such time as the Issuers shall determine. Although the Issuer intends to notify holders of defects or irregularities with respect to tenders of old notes, neither the Issuer, the Exchange Agent, nor any other person shall be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give such notification. Tenders of old notes will not be deemed to have been made until such defects or irregularities have been cured or waived. Any old notes received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the Exchange Agent to the tendering holders, unless otherwise provided in the Letter of Transmittal, promptly following the Expiration Date.

The Issuer reserves the absolute right to waive, in whole or part, up to the expiration of the Exchange Offer, any of the conditions to the Exchange Offer set forth in the Prospectus or in this Letter of Transmittal.

No alternative, conditional, irregular or contingent tender of old notes will be accepted.

IMPORTANT: BY USING THE ATOP PROCEDURES TO TENDER OLD NOTES, YOU WILL NOT BE REQUIRED TO DELIVER THIS LETTER OF TRANSMITTAL TO THE EXCHANGE AGENT. HOWEVER, YOU WILL BE BOUND BY ITS TERMS, AND YOU WILL BE DEEMED TO HAVE MADE THE ACKNOWLEDGMENTS AND THE REPRESENTATIONS AND WARRANTIES IT CONTAINS, JUST AS IF YOU HAD SIGNED IT.

Under the provisions of Article 2.02.A(16) and Article 2.02-1 of the Texas Business Corporation Act and Article VI of our Amended and Restated Bylaws, we may indemnify our directors, officers, employees and agents and purchase and maintain liability insurance for those persons. Article 2.02-1 provides that any director or officer of a Texas corporation may be indemnified against judgments, penalties, fines, settlements and reasonable expenses actually incurred by him in connection with or in defending any action, suit or proceeding in which he is a party by reason of his position. With respect to any proceeding arising from actions taken in his official capacity as a director or officer, he may be indemnified so long as it shall be determined that he conducted himself in good faith and that he reasonably believed that such conduct was in the corporation’s best interests. In cases not concerning conduct in his official capacity as a director or officer, a director may be indemnified as long as he reasonably believed that his conduct was not opposed to the corporation’s best interests. In the case of any criminal proceeding, a director or officer may be indemnified if he had no reasonable cause to believe his conduct was unlawful. If a director or officer is wholly successful, on the merits or otherwise, in connection with such a proceeding, such indemnification is mandatory.

Our articles of incorporation provide for indemnification of our directors to the full extent permitted by applicable law. Article VI of our bylaws provides, in general, that we will indemnify our directors under the circumstances permitted under the Texas Business Corporation Act. In addition, we have entered into indemnification agreements with our directors. These agreements provide that if a director is a party or is threatened to be made a party to any action, we will indemnify the director and hold the director harmless against any and all liabilities or losses incurred in connection with such action if it arises out of or is related to the fact that the director is or was serving as a director, to the fullest extent permitted by then applicable law. Further, if Texas law is amended to authorize the further elimination or limitation of directors’ liability, then the liability of our directors will automatically be limited to the fullest extent provided by law.

Schedules are omitted because they either are not required or are not applicable or because equivalent information has been included in the financial statements, the notes thereto or elsewhere herein.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by a registrant of expenses incurred or paid by a director, officer or controlling person of such registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, such registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

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

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

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

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

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

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

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