Table of Contents

        In this prospectus, we refer to the notes to be issued in the exchange offer as the "new notes," and we refer to the $450 million aggregate principal amount of our 55/8% senior notes due 2022 issued on January 23, 2014 as the "old notes." We refer to the new notes and the old notes collectively as the "notes." References to the "issuer" refer to Laredo Petroleum, Inc., a Delaware corporation. References to "subsidiary" or "guarantor" refer to Laredo Midstream Services, LLC, a Delaware limited liability company. References to "Laredo," "we," "us" or "our" refer to Laredo Petroleum Holdings, Inc., a Delaware corporation, together with its subsidiaries, including the issuer, for periods prior to our internal corporate reorganization on December 31, 2013, and to Laredo Petroleum, Inc. together with the subsidiary for periods after our internal corporate reorganization, unless otherwise indicated or the context otherwise requires. See "Summary—Corporate History and Structure" for more information. "Laredo Inc." refers solely to Laredo Petroleum, Inc. after our internal corporate reorganization and not any subsidiary.

        This prospectus incorporates important business and financial information about us that is not included or delivered with this prospectus. Such information is available without charge to holders of old notes upon written or oral request made to Laredo Petroleum, Inc., 15 W. Sixth Street, Suite 900, Tulsa, Oklahoma 74119, Attention: Investor Relations (Telephone (918) 513-4570). To obtain timely delivery of any requested information, holders of old notes must make any request no later than May 14, 2014, a date that is five business days prior to the expiration of the exchange offer.


CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

        The information in this prospectus includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All statements, other than statements of historical fact included in this prospectus, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this prospectus, the words "could," "believe," "anticipate," "intend," "estimate," "expect," "project," "may," "will," "should," "plan," "predict," "potential," "foresee," "goal," "pursue," "target," "continue," "suggest" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on our current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. Among the factors that significantly impact our business and could impact our business in the future are:

Table of Contents

        These forward-looking statements involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. Forward-looking statements should, therefore, be considered in light of various factors, including those set forth in this prospectus under "Risk Factors" and elsewhere in this prospectus, as well as the risk factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2013 (the "2013 Annual Report") and the other documents incorporated by reference herein. In light of such risks and uncertainties, we caution you not to rely on these forward-looking statements in deciding whether to invest in the notes.

        Reserve engineering is a process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reservoir engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered.

        These forward-looking statements speak only as of the date of this prospectus, and we do not undertake any obligation to publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events, except as required by applicable securities laws.

PROSPECTUS SUMMARY

        This summary highlights some of the information contained in this prospectus and does not contain all of the information that may be important to you. You should read this entire prospectus, the documents incorporated by reference and the documents to which we refer you before making an investment decision. You should carefully consider the information set forth under "Risk Factors" beginning on page 11 of this prospectus and discussed in the 2013 Annual Report, and the other cautionary statements described in this prospectus. In addition, certain statements include forward looking information that involves risks and uncertainties. See "Cautionary Statement Regarding Forward-Looking Statements."

Company Overview

        We are an independent energy company focused on the exploration, development and acquisition of oil and natural gas properties primarily in the Permian region of the United States. The oil and liquids-rich Permian Basin in West Texas is characterized by multiple target horizons, extensive production histories, long-lived reserves, high drilling success rates and high initial production rates. Since our inception, we have rapidly grown our reserves, production and cash flow through both our drilling program and strategic acquisitions, including our July 2011 acquisition of Broad Oak Energy, Inc. ("Broad Oak"), a Delaware corporation. As of December 31, 2013, we had assembled 202,084 net acres in the Permian Basin and had total proved reserves, presented on a two-stream basis, of 203,615 MBOE. Our drilling activity has been and is expected to continue to be focused on oil opportunities in the Permian Basin.

        We maintain a financial profile that provides operational flexibility. At March 31, 2014, we had $812.5 million available for borrowings under our senior secured credit facility and total debt of $1.5 billion, of which no amount was outstanding under our senior secured credit facility. Our total debt, less available cash on the balance sheet, was 1.8 times our Adjusted EBITDA (a non-GAAP financial measure) for the year ended December 31, 2013. We believe that our operating cash flow and the aforementioned liquidity sources provide us with the capability to implement our planned exploration and development activities as well as the ability to accelerate our capital program, if deemed appropriate.

Corporate History and Structure

        Laredo Petroleum Holdings, Inc. ("Holdings") was incorporated in August 2011 pursuant to the laws of the State of Delaware for purposes of a corporate reorganization and initial public offering ("IPO"). The corporate reorganization, pursuant to which Laredo Petroleum, LLC was merged with and into Holdings, with Holdings surviving the merger, was completed on December 19, 2011 (the "Corporate Reorganization"). Laredo Petroleum, LLC was formed in 2007 pursuant to the laws of the State of Delaware by affiliates of Warburg Pincus LLC ("Warburg Pincus"), our institutional investor, and the management of Laredo Petroleum, Inc., which was founded in 2006 by Randy A. Foutch, our Chairman and Chief Executive Officer, to acquire, develop and operate oil and natural gas properties in the Permian and Mid-Continent regions of the United States. In the Corporate Reorganization, all of the outstanding preferred equity interests and certain of the incentive equity interests in Laredo Petroleum, LLC were exchanged for shares of common stock of Holdings. Holdings completed an IPO of its common stock on December 20, 2011. As of March 31, 2014, Warburg Pincus owned 43.8% of our common stock.

        On July 1, 2011, we completed the acquisition of Broad Oak, which became a wholly-owned subsidiary of Laredo Petroleum, Inc. Broad Oak was formed in 2006 with financial support from its management and Warburg Pincus. On July 19, 2011, we changed the name of Broad Oak to Laredo Petroleum—Dallas, Inc.

Table of Contents

        Effective December 31, 2013, we completed an internal corporate reorganization, which simplified our corporate structure. Our two former subsidiaries Laredo Petroleum Texas, LLC and Laredo Petroleum—Dallas, Inc. were merged with and into Laredo Petroleum, Inc. The sole remaining wholly-owned subsidiary of Laredo Petroleum, Inc., formerly known as Laredo Gas Services, LLC, changed its name to Laredo Midstream Services, LLC. Laredo Petroleum, Inc., a wholly-owned subsidiary of Holdings, merged with and into Holdings with Holdings surviving and changing its name to "Laredo Petroleum, Inc."

        Laredo Inc. is the borrower under our senior secured credit facility, as well as the issuer of the notes, our $550 million 91/2% senior unsecured notes due 2019 (the "2019 senior notes") issued in January and October 2011, and our $500 million 73/8% senior unsecured notes due 2022 issued in April 2012 (the "April 2022 senior notes" and together with the 2019 senior notes, the "existing registered notes"). Our subsidiary, Laredo Midstream Services, LLC, is a guarantor of the obligations under our senior secured credit facility, the notes and the existing registered notes.

The Exchange Offer

        On January 23, 2014, we completed a private offering of $450 million aggregate principal amount of the old notes. We entered into a registration rights agreement with the initial purchasers in connection with this 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 of the initial issuance of the old notes issued on January 23, 2014.

Old Notes

  On January 23, 2014, we issued $450 million aggregate principal amount of 55/8% senior notes due 2022.

The exchange offer will expire at 5:00 p.m., New York City time, on May 21, 2014, unless we decide to extend it.

Conditions 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 SEC.

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, which we call "ATOP," 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 confirms that:

    

 

DTC has received your instructions to exchange your notes, and

    

 

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

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.

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 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

  Laredo Petroleum, Inc.

New Notes Offered

 

$450 million aggregate principal amount of 55/8% senior notes due 2022, registered under the Securities Act. The old notes and the new notes will be treated as a single class of securities under the indenture, including, without limitation, for purposes of waivers, amendments, redemptions and offers to purchase.

Maturity Date

 

January 15, 2022.

Interest

 

The new notes will bear interest at a rate of 55/8% per annum, payable semi-annually, in cash in arrears, on January 15 and July 15 of each year, commencing on the first such date next following the date on which the exchange offer is consummated.

Guarantees

 

The issuer's sole existing subsidiary and certain of the issuer's future domestic restricted subsidiaries will fully and unconditionally guarantee, jointly and severally, the new notes so long as each such entity guarantees or becomes an obligor of the issuer's senior secured credit facility or other debt of the issuer or any restricted subsidiary of the issuer, in each case, in excess of $5 million. Not all of the issuer's future subsidiaries will be required to become guarantors. If the issuer cannot make payments on the new notes when they are due, the guarantors must make them instead. Please read "Description of the Notes—Guarantees."

 

Each guarantee will rank:

 

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

 

equally in right of payment with all existing and future senior unsecured indebtedness of the guarantor, including the guarantee of the existing registered notes; and

 

effectively junior in right of payment to all existing and future secured indebtedness of the guarantor, including its guarantee of indebtedness under our senior secured credit facility, to the extent of the value of the assets securing such indebtedness.

Table of Contents

 

As of December 31, 2013, on a pro forma basis after giving effect to the offering of $450 million of old notes on January 23, 2014 and the application of the net proceeds therefrom, the guarantee of the notes would not have been effectively subordinated to any secured indebtedness and the guarantor would have guaranteed approximately $1.5 billion of senior unsecured indebtedness (including the old notes). The issuer would have had approximately $812.5 million of borrowing capacity available under its senior secured credit facility, subject to compliance with financial covenants, the guarantee of which would be effectively senior to the guarantee of the notes (to the extent of the value of the assets securing such indebtedness).

Ranking

 

The new notes will be the issuer's unsecured senior obligations. Accordingly, they will rank:

 

senior in right of payment to any future subordinated indebtedness of the issuer;

 

equally in right of payment with all existing and future senior indebtedness, including the existing registered notes;

 

effectively junior in right of payment to all of the issuer's existing and future secured indebtedness, including indebtedness under the issuer's senior secured credit facility, to the extent of the value of the assets of the issuer securing such indebtedness; and

 

effectively junior to all indebtedness and other liabilities of any future non-guarantor subsidiaries to the extent of the assets of those subsidiaries.

 

As of December 31, 2013, on a pro forma basis after giving effect to the offering of $450 million of old notes on January 23, 2014 and the application of the net proceeds therefrom, the issuer would have had approximately $1.5 billion of total indebtedness (including the old notes) of which none would be secured indebtedness to which the notes would be effectively subordinated. The issuer would have had approximately $812.5 million of borrowing capacity available under its senior secured credit facility, subject to compliance with financial covenants, all of which would be effectively senior to the notes (to the extent of the value of the assets securing such indebtedness).

Table of Contents

Optional Redemption

 

The issuer will have the option to redeem the new notes, in whole or in part, at any time on or after January 15, 2017, at the redemption prices described in this prospectus under the heading "Description of the Notes—Optional Redemption," together with any accrued and unpaid interest to, but not including, the date of redemption. In addition, before January 15, 2017, the issuer may (i) redeem all or any part of the notes at the make-whole price set forth under "Description of the Notes—Optional Redemption" or (ii) at any time or from time to time, redeem up to 35% of the aggregate principal amount of the notes with the net proceeds of a public or private equity offering at a redemption price of 105.625% of the principal amount of the notes, plus any accrued and unpaid interest to the date of redemption, if at least 65% of the aggregate principal amount of the notes issued under the indenture governing the notes remains outstanding immediately after such redemption and the redemption occurs within 180 days of the closing date of such equity offering. If a change of control occurs prior to January 15, 2015, the issuer may redeem all, but not less than all, of the notes at a redemption price equal to 110% of the principal amount of the notes plus any accrued and unpaid interest to, but not including, the date of redemption.

Change of Control

 

If a change of control event occurs, each holder of new notes may require the issuer to repurchase all or a portion of its new notes for cash at a price equal to 101% of the aggregate principal amount of such new notes, plus any accrued and unpaid interest to, but not including, the date of repurchase.

Certain Other Covenants

 

The indenture contains covenants that limit, among other things, the ability of the issuer and some of its subsidiaries to:

 

pay distributions or dividends on, or purchase, redeem or otherwise acquire, equity interests;

 

make certain investments;

 

incur additional indebtedness or liens;

 

sell certain assets or merge with or into other companies;

 

engage in transactions with affiliates; and

 

enter into sale and leaseback transactions.

 

These covenants are subject to a number of important qualifications and limitations. In addition, substantially all of the covenants will be suspended before the new notes mature if both of two specified ratings agencies assign the new notes an investment grade rating in the future and no event of default exists under the indenture governing the new notes. See "Description of the Notes—Certain Covenants."

Transfer Restrictions, Absence of a Public Market for the New Notes

 

The new notes generally will be freely transferable, but will also be new securities for which there will not initially be a market. There can be no assurance as to the development of liquidity of any market for the new notes. We do not intend to apply for a listing of the new notes on any securities exchange or any automated dealer quotation system.

Risk Factors

 

Investing in the new notes involves risks. See "Risk Factors" beginning on page 11 of this prospectus and in the 2013 Annual Report for a discussion of certain factors you should consider in evaluating whether or not to tender your old notes.

Form of Exchange Notes

 

The new notes will be represented initially by one or more global notes. The global new notes will be deposited with the trustee, as custodian for DTC.

Trustee, Registrar and Exchange Agent

 

Wells Fargo Bank, National Association.

Governing Law

 

The new notes and the indenture governing the new notes will be governed by and construed in accordance with the laws of the State of New York.

Same-Day Settlement

 

The global new notes will be shown on, and transfers of the global new notes will be effected only through, records maintained in book entry form by DTC and its direct and indirect participants. The new notes are expected to trade in DTC's Same Day Funds Settlement System until maturity or redemption. Therefore, secondary market trading activity in the new notes will be settled in immediately available funds.

  For the years ended December 31,  
 
  2013   2012   2011   2010   2009  

Ratio of earnings to fixed charges (1)

  2.9x   2.1x   4.3x   4.4x     (2)

(1)
For purposes of computing the ratio of earnings to fixed charges, "earnings" consists of pretax income (loss) from continuing operations, excluding income from our equity method investee, plus fixed charges less interest capitalized. "Fixed charges" represents interest incurred, amortization of deferred debt offering costs and that portion of rental expense on operating leases deemed to be the equivalent of interest.

(2)
Due to our net operating loss for the year ended December 31, 2009, the ratio of coverage was less than 1:1. To achieve the ratio coverage of 1:1, we would have needed additional earnings of approximately $256.2 million.

RISK FACTORS

        Investing in the notes involves risks. You should carefully consider the information in this prospectus, including the matters addressed under "Cautionary Statement Regarding Forward-Looking Statements" and the risks below, as well as those discussed in the 2013 Annual Report, together with all of the other information included in, or incorporated by reference into, this prospectus, before participating in the exchange offer.

Risks Related to the Notes

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

        Our ability to make scheduled payments on or to refinance our debt obligations, including the notes, depends on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, including the notes. As a result of concern about the stability of financial markets generally and the solvency of counterparties specifically, the cost of obtaining money from the credit markets has increased for certain companies as many lenders and institutional investors have increased interest rates, enacted tighter lending standards and reduced and, in some cases, ceased to provide funding to borrowers.

        If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance our indebtedness, including the notes. Our ability to restructure or refinance our debt will depend on the condition of the capital markets and the bank markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of our existing or future debt instruments and the indenture governing the notes may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness. In the absence of sufficient cash flows and capital resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. Our senior secured credit facility, the indentures governing the existing registered notes and the indenture governing the notes currently restrict our ability to dispose of assets and use the proceeds from such disposition. We may not be able to consummate those dispositions, and the proceeds of any such disposition may not be adequate to meet any debt service obligations then due. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

        The borrowing base under our senior secured credit facility is $812.5 million with an aggregate of $812.5 million available for borrowings, subject to covenant compliance. Our next scheduled borrowing base redetermination is expected to occur in May 2014. In the future, we may not be able to access adequate funding under our senior secured credit facility as a result of a decrease in our borrowing base due to the issuance of new indebtedness, the outcome of a subsequent semi-annual borrowing base redetermination or an unwillingness or inability on the part of our lending counterparties to meet their funding obligations and the inability of other lenders to provide additional funding to cover the defaulting lender's portion. Declines in commodity prices could result in a determination to lower the borrowing base in the future and, in such a case, we could be required to repay any indebtedness in excess of the redetermined borrowing base. As a result, we may be unable to implement our drilling and development plan, make acquisitions or otherwise carry out our business plan, which would have a

11


Table of Contents

material adverse effect on our financial condition and results of operations and impair our ability to service the notes.

Despite our indebtedness level, we still may be able to incur significant additional amounts of debt.

        As of December 31, 2013, on a pro forma basis after giving effect to the offering of old notes and the application of the net proceeds therefrom, we would have had approximately $1.5 billion of indebtedness outstanding, including the old notes, as well as approximately $812.5 million of borrowing capacity available under our senior secured credit facility subject to compliance with financial covenants. We may be able to incur substantial additional indebtedness, including secured indebtedness, in the future. The restrictions on the incurrence of additional indebtedness contained in the indenture governing the notes, the indentures governing the existing registered notes and our senior secured credit facility are subject to a number of significant qualifications and exceptions, and under certain circumstances, the amount of indebtedness, including secured indebtedness, that could be incurred in compliance with these restrictions could be substantial.

        If new debt is added to our existing debt levels, the related risks that we face would increase and may make it more difficult to satisfy our existing financial obligations, including those relating to the notes. In addition, the indenture governing the notes does not prevent us from incurring obligations that do not constitute indebtedness under the indenture. See "Description of Other Indebtedness—Senior Secured Credit Facility" and "Description of the Notes."

        If we incur any additional indebtedness or other obligations, including trade payables, that rank equally with the notes, the holders of those obligations will be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding up of our company. This may have the effect of reducing the amount of proceeds paid to you.

Our debt agreements contain restrictions that will limit our flexibility in operating our business.

        The indenture governing the notes, the indentures governing the existing registered notes and our senior secured credit facility each contain, and any future indebtedness we incur may contain, various covenants that limit our ability to engage in specified types of transactions. These covenants limit our ability to, among other things:

        As a result of these covenants, we are limited in the manner in which we may conduct our business and we may be unable to engage in favorable business activities or finance future operations or our capital needs. In addition, the covenants in our senior secured credit facility require us to maintain a minimum working capital ratio and minimum interest coverage ratio and also limit our capital expenditures. A breach of any of these covenants could result in a default under one or more of these agreements, including as a result of cross default provisions and, in the case of our senior secured credit facility, permit the lenders to cease making loans to us. Upon the occurrence of an event of default under our senior secured credit facility, the lenders could elect to declare all amounts

outstanding under our senior secured credit facility to be immediately due and payable and terminate all commitments to extend further credit. Such actions by those lenders could cause cross defaults under our other indebtedness, including the notes. If we were unable to repay those amounts, the lenders under our senior secured credit facility could proceed against the collateral granted to them to secure that indebtedness. We pledged a significant portion of our assets as collateral under our senior secured credit facility. If the lenders under our senior secured credit facility accelerate the repayment of the borrowings thereunder, the proceeds from the sale of or foreclosure upon such assets will first be used to repay debt under our senior secured credit facility, and we may not have sufficient assets to repay our unsecured indebtedness thereafter, including the notes.

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

        If we are unable to comply with the restrictions and covenants in the indenture governing the notes, in the indentures governing the existing registered notes, in our senior secured credit facility, or in any future debt financing agreements, there could be a default under the terms of these agreements. Our ability to comply with these restrictions and covenants, including meeting financial ratios and tests, may be affected by events beyond our control. As a result, we cannot assure you that we will be able to comply with these restrictions and covenants or meet these financial ratios or tests. Any default under the agreements governing our indebtedness, including a default under our senior secured credit facility, the indentures governing the existing registered notes or the indenture governing the notes, that is not waived by the requisite number of lenders, and the remedies sought by the holders of such indebtedness, could prevent us from paying principal, premium, if any, and interest on the notes and substantially decrease the market value of the notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants in the instruments governing our indebtedness (including covenants in our senior secured credit facility), we could be in default under the terms of these agreements. In the event of such default:

If our operating performance declines, we may in the future need to obtain waivers from the required lenders under our senior secured credit facility or any other indebtedness to avoid being in default. If we breach our covenants under our senior secured credit facility or any other indebtedness and seek a waiver, we may not be able to obtain a waiver from the required lenders on terms that are acceptable to us, if at all. If this occurs, we would be in default under our senior secured credit facility or any other indebtedness, the lenders could exercise their rights, as described above, and we could be forced into bankruptcy or liquidation.

The notes and the guarantee are unsecured and effectively subordinated to our secured indebtedness and to the debt of any non-guarantor subsidiaries.

        The notes and the guarantee will be general unsecured senior obligations of Laredo Inc. and the subsidiary guarantor, respectively, and will rank effectively junior to all of Laredo Inc.'s and the

13


Table of Contents

subsidiary guarantor's existing and future secured indebtedness, including indebtedness under our senior secured credit facility, to the extent of the value of the collateral securing such indebtedness. As of December 31, 2013, we had no secured indebtedness under our senior secured credit facility. As of December 31, 2013, on a pro forma basis after giving effect to the offering of old notes and the application of the proceeds therefrom, we would have had approximately $1.5 billion of senior unsecured indebtedness (including the notes) and the issuer would be able to draw up to approximately $812.5 million of secured debt under our senior secured credit facility, subject to compliance with financial covenants, which debt would be effectively senior to the notes and guarantees (to the extent of the value of the assets securing such indebtedness). The notes and the guarantee will also be effectively subordinated to any indebtedness of any future non-guarantor subsidiaries to the extent of the assets of those subsidiaries.

        If we were unable to repay indebtedness under our senior secured credit facility, the lenders under that facility could foreclose on the pledged assets to the exclusion of holders of the notes, even if an event of default exists under the indenture governing the notes at such time. Furthermore, if the lenders foreclose and sell the pledged equity interests in the subsidiary guarantor in a transaction permitted under the terms of the indenture governing the notes, then the subsidiary guarantor will be released from its guarantee of the notes automatically and immediately upon such sale. In any such event, because the notes are not secured by any of such assets or by the equity interests in the subsidiary guarantor, it is possible that there would be no assets from which your claims could be satisfied or, if any assets existed, they might be insufficient to satisfy your claims in full.

        If we or the subsidiary guarantor is declared bankrupt, becomes insolvent or is liquidated, dissolved or reorganized, any of its secured indebtedness will be entitled to be paid in full from its assets or the assets of the subsidiary guarantor securing that indebtedness before any payment may be made with respect to the notes or the guarantee, and creditors of any future non-guarantor subsidiaries would be paid before you receive any amounts due under the notes to the extent of the value of our equity interests in such subsidiaries. Holders of the notes will participate ratably in our and the subsidiary guarantor's remaining assets with all holders of any of our and the subsidiary guarantor's unsecured indebtedness that do not rank junior in right of payment to the notes, including the existing registered notes, 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 or the guarantees. As a result, holders of the notes would likely receive less, ratably, than holders of secured indebtedness and holders of debt of any future non-guarantor subsidiaries.

Repayment of our debt, including the notes, is partially dependent on cash flow generated by our subsidiary.

        Repayment of our indebtedness, including the notes, is partially dependent on the generation of cash flow by our subsidiary and its ability to make such cash available to us, by dividend, debt repayment or otherwise. Unless they are guarantors of the notes, our future subsidiaries will not have any obligation to pay amounts due on the notes or to make funds available for that purpose. Future non-guarantor subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness, including the notes. Each subsidiary is a distinct legal entity and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from future non-guarantor subsidiaries. While the indenture governing the notes will limit the ability of our non-guarantor subsidiaries to incur consensual restrictions on their ability to pay dividends or make other intercompany payments to us, these limitations are subject to certain qualifications and exceptions. In the event that we do not receive distributions from any future non-guarantor subsidiaries, we may be unable to make required principal and interest payments on our indebtedness, including the notes.

Table of Contents

A financial failure by Laredo Inc. or the subsidiary guarantor may result in Laredo Inc.'s assets and the assets of any or all of those entities becoming subject to the claims of all creditors of those entities.

        A financial failure by Laredo Inc. or the subsidiary guarantor could affect payment of the notes if a bankruptcy court were to substantively consolidate Laredo Inc. and the subsidiary guarantor. If a bankruptcy court substantively consolidated Laredo Inc. and the subsidiary guarantor, the assets of each entity would become subject to the claims of creditors of all entities. This would expose holders of notes 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" provisions of the U.S. bankruptcy code. Under these provisions, the notes could be restructured over your objections as to their general terms, primarily interest rate and maturity.

We may not be able to repurchase the notes in certain circumstances.

        Under the terms of the indentures governing the existing registered notes and the indenture governing the notes, we may be required to repurchase all or a portion of the existing registered notes and your notes if we sell certain assets or in the event of a change of control of Laredo Inc. In such event, we may not have enough funds to pay the repurchase price on a purchase date. Our senior secured credit facility provides, and any future credit facilities or other debt agreements to which we become a party may provide, that our obligation to repurchase the existing registered notes or the notes would be an event of default under such agreement. As a result, we may be restricted or prohibited from repurchasing such notes. If we are prohibited from repurchasing such notes, we could seek the consent of our then-existing lenders to repurchase such notes, or we could attempt to refinance the borrowings that contain such prohibition. If we are unable to obtain any such consent or refinance such borrowings, we would not be able to repurchase such notes. Our failure to repurchase tendered notes would constitute a default under the indentures governing the existing registered notes and the indenture governing the notes and would constitute a default under the terms of our existing, or might constitute a default under the terms of our future, indebtedness.

        The definition of "change of control" includes a phrase relating to the sale, assignment, conveyance, exchange, lease or other disposition, in one or a series of related transactions, of "all or substantially all" of the assets of Laredo Inc. and its restricted subsidiaries, taken as a whole. Thus, only asset dispositions constituting a "series of related transactions" are aggregated in determining whether a "change of control" arising from the sale of "substantially all" of the assets has taken place. Moreover, the term "all or substantially all," as used in the definition of change of control, has not been interpreted under New York law (which is the governing law of the indenture governing the notes) to represent a specific quantitative test. Therefore, if holders of the notes exercise their right to require Laredo Inc. to repurchase their notes under the indenture as a result of a sale, assignment, conveyance, transfer, exchange, lease or other disposition of less than all of the assets of Laredo Inc. and its restricted subsidiaries taken as a whole and Laredo Inc. elected to contest such election, it is not clear how a court applying New York law would interpret the phrase.

        Recent Delaware case law has raised the possibility that the obligation of a Delaware corporation to make a change of control repurchase offer for its debt that arises as a result of a failure of such corporation to have "continuing directors" compose a majority of its board of directors may be unenforceable on public policy grounds under Delaware law to the extent such obligation involves a breach of fiduciary duty. Additionally, recent Delaware case law suggests that, in the event that incumbent directors are replaced as a result of a contested election, issuers of debt may nevertheless avoid triggering a change of control under a clause similar to that contained in the definition of change of control if the outgoing directors were to approve the new directors for the purpose of such change of control clause.

15


Table of Contents

        The term "change of control" is limited to certain specified transactions and may not include other events that might adversely affect our financial condition. Our obligation to repurchase the existing registered notes or the notes upon a change of control would not necessarily afford holders of such notes protection in the event of a highly leveraged transaction, reorganization, merger or similar transaction. In addition, holders of such notes may not be entitled to require us to purchase their notes in certain circumstances involving a significant change in the composition of Laredo Inc.'s board of directors, including in connection with a proxy contest in which Laredo Inc.'s board of directors does not endorse or recommend a dissident slate of directors but approves them as directors for purposes of the "change of control" definition in the indenture. See "Description of the Notes—Change of Control."

Federal and state fraudulent transfer laws may permit a court to void the notes and the guarantees, subordinate claims in respect of the notes and the guarantees and require noteholders to return payments received and, if that occurs, you may not receive any payments on the notes.

        Federal and state fraudulent transfer and conveyance statutes may apply to the issuance of the notes and the incurrence of any guarantees of the notes, including the guarantee by the guarantors entered into upon issuance of the notes and subsidiary guarantees (if any) that may be entered into thereafter under the terms of the indenture governing the notes. Under federal bankruptcy law and comparable provisions of state fraudulent transfer or conveyance laws, which may vary from state to state, the notes or guarantees could be voided as a fraudulent transfer or conveyance if the court found that (1) we or any of the guarantors, as applicable, issued the notes or incurred the guarantees with the intent of hindering, delaying or defrauding creditors or (2) we or any of the guarantors, as applicable, received less than the reasonably equivalent value or fair consideration in return for either issuing the notes or incurring the guarantees and, in the case of (2) only, one of the following is also true at the time thereof:

        A court would likely find that we or a guarantor did not receive reasonably equivalent value or fair consideration for the notes or such guarantee if we or such guarantor did not substantially benefit directly or indirectly from the issuance of the notes or the applicable guarantee. As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or an antecedent debt is secured or satisfied. A debtor will generally not be considered to have received value in connection with a debt offering if the debtor uses the proceeds of that offering to make a dividend payment or otherwise retire or redeem equity securities issued by the debtor.

        We cannot be certain as to the standards a court would use to determine whether or not we or the guarantors were solvent at the relevant time or, regardless of the standard that a court uses, that the issuance of the guarantees would not be further subordinated to our or any of our guarantors' other

16


Table of Contents

debt. Generally, however, an entity would be considered insolvent at the time it incurred indebtedness if:

        If a court were to find that the issuance of the notes or the incurrence of the guarantee was a fraudulent transfer or conveyance, the court could void the payment obligations under the notes or such guarantee or further subordinate the notes or such guarantee to presently existing and future indebtedness of ours or of the related guarantor, or require the holders of the notes to repay any amounts received with respect to such guarantee. In the event of a finding that a fraudulent transfer or conveyance occurred, you may not receive any repayment on the notes.

        Although each guarantee will contain a provision intended to limit that guarantor's liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent transfer, this provision may not be effective to protect those guarantees from being voided under fraudulent transfer law, or may reduce that guarantor's obligation to an amount that effectively makes its guarantee of limited value or worthless.

        In a recent Florida bankruptcy case, this kind of provision was found to be unenforceable and, as a result, the subsidiary guarantees in that case were found to be fraudulent transfers. If a court were to rely on this case as precedent in litigation under the indenture, the risk that the guarantees will be found to be fraudulent transfers will be significantly increased.

        Finally, as a court of equity, a bankruptcy court may subordinate the claims in respect of the notes and the guarantees to the claims of other creditors under the principle of equitable subordination if the court determines that: (1) the holder of the notes engaged in inequitable conduct to the detriment of other creditors; (2) such inequitable conduct resulted in injury to our or the applicable guarantor's other creditors or conferred an unfair advantage upon the holder of the notes; and (3) equitable subordination is not inconsistent with the provisions of applicable bankruptcy law.

Your ability to transfer the notes may be limited by the absence of an active trading market, and there is no assurance that any active trading market will develop for the notes.

        We cannot assure you that, even following registration or exchange of the old notes for new notes, an active trading market for the notes will exist, and we will have no obligation to create such a market. No assurance can be given as to the liquidity of or trading market for the old notes or the new notes.

        The liquidity of any trading market for the notes and the market prices quoted for the notes 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.

The market value of the notes may be subject to substantial volatility.

        Historically, the market for high-yield debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. We cannot assure you that the market, if any, for the notes or the new notes will be free from similar disruptions or that any such disruptions will not adversely affect the prices at which you may sell your notes. As has been evident in

17


Table of Contents

connection with the recent turmoil in global financial markets, the entire high-yield debt market can experience sudden and sharp price swings, which can be exacerbated by factors such as (1) large or sustained sales by major investors in high-yield debt, (2) a default by a high profile issuer or (3) a change in investors' psychology regarding high-yield debt. A real or perceived economic downturn or higher interest rates could cause a decline in the market value of the notes. Moreover, if one of the major rating agencies lowers its credit rating on us or the notes, the market value of such notes will likely decline. Therefore, we cannot assure you that you will be able to sell your notes at a particular time or, in the event you are able to sell your notes, that the price that you receive will be favorable.

Many of the covenants contained in the indenture governing the notes will be suspended if the notes are rated investment grade by both Standard & Poor's Ratings Services and Moody's Investors Service, Inc.

        Many of the covenants in the indenture governing the notes will be suspended for so long as the notes are rated investment grade by both Standard & Poor's Ratings Services and Moody's Investors Service, Inc., provided at such time no event of default under the indenture governing the notes has occurred and is continuing. These covenants will be reinstated if the rating assigned by either rating agency declines below investment grade. These covenants will restrict, among other things, our ability to pay dividends, to incur indebtedness 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, suspension of these covenants would allow us to engage in certain transactions that would not be permitted while these covenants were in force. See "Description of the Notes—Certain Covenants—Covenant Suspension."

Variable rate indebtedness subjects us to the risk of higher interest rates, which could cause our debt service obligations to increase significantly.

        Certain of our current borrowings are, and future borrowings (including borrowings under our senior secured credit facility) may be, at variable rates of interest, and, therefore, expose us to the risk of increased interest rates. If interest rates increase, our debt service obligations on our variable rate indebtedness would increase even if our outstanding indebtedness remained the same, thereby causing our net income and cash available for servicing our indebtedness to be lower than it would have been had interest rates not increased. For example, as of March 31, 2014, we had $812.5 million of borrowing capacity under the senior secured credit facility, subject to compliance with financial covenants. The impact of a 1.0% increase in interest rates on an assumed borrowing of the full $812.5 million currently available under the senior secured credit facility would result in increased annual interest expense of approximately $8.1 million and a corresponding decrease in our net income before the effects of increased interest rates on the value of our interest rate contracts.

Risks Related to the Exchange Offer

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.

        The issuer 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

18


Table of Contents

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 the old notes outstanding.

The consummation of the exchange offer may not occur.

        We are not obligated to complete the exchange offer under certain circumstances. See "Exchange Offer—Conditions to the Exchange Offer." Even if the exchange offer is completed, it may not be completed on the schedule described in this prospectus. Accordingly, holders participating in the exchange offer may have to wait longer than expected to receive their new notes, during which time those holders of old notes will not be able to effect transfers of their old notes tendered in the exchange offer.

You may be required to deliver prospectuses and comply with other requirements in connection with any resale of the new notes.

        If you tender your old notes for the purpose of participating in a distribution of the new notes, you will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the new notes. In addition, if you are a broker-dealer that receives new notes for your own account in exchange for old notes that you acquired as a result of market-making activities or any other trading activities, you will be required to acknowledge that you will deliver a prospectus in connection with any resale of such new notes.

EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

        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 do the following:

        We agreed to offer 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 20 business days after the date we publish, or send to the holders of the old notes, notice of the exchange offer.

        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 or, if no interest has been paid on such old note, from January 23, 2014, but interest payable on any interest payment date on any new note issued in exchange for any old note after a regular record date and prior to such interest payment date will be paid to the holder of record of such old note on such record date. The registration rights agreement also contains agreements 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 trading activities (other than old notes acquired directly from us) 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 of 180 days after the completion of the exchange offer, which period may be extended under certain circumstances.

        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:

20


Table of Contents

        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 old notes held by any holder who provides us with certain information for inclusion in the shelf registration statement if:

        We have agreed to use commercially reasonable efforts to keep the shelf registration statement continuously effective until the earlier of one year following its effective date and such time as all notes covered by the shelf registration statement have been sold. We refer to this period as the "shelf effectiveness period."

        The registration rights agreement provides that if the exchange offer is not completed (or, if required, the shelf registration statement is not declared effective or does not automatically become effective when required) on or before the 365th day following the date of the issuance of the old notes (January 23, 2014) (or the date the shelf registration statement is required to be declared effective or automatically becomes effective, as the case may be) then additional interest shall accrue on the principal amount of the old notes at a rate of 0.25% per annum for the first 90-day period immediately following such date and by an additional 0.25% per annum with respect to each subsequent 90-day period, up to a maximum additional rate of 1.00% per annum thereafter, until the exchange offer is completed, the shelf registration statement is declared effective or, if such shelf registration statement ceased to be effective (subject to certain exceptions), again becomes effective or until the second anniversary of the issue date of the old notes, unless such period is extended, as described in the registration rights agreement.

        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 and to provide comments on the shelf registration statement within the time periods set forth in the registration rights agreement in order to have their old notes included in the shelf registration statement.

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

Table of Contents

        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 which includes this prospectus.

        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."

Terms of the Exchange Offer

        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 $2,000 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, $450,000,000 in aggregate principal amount of the old notes is outstanding. This prospectus and the letter of transmittal are being sent to DTC, the sole registered holder 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 and the Exchange Act and the rules and regulations of the SEC. Old notes that the holders thereof do not tender for exchange in the 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 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 connection 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.

Expiration Date

        The exchange offer will expire at 5:00 p.m., New York City time, on May 21, 2014, unless, in our sole discretion, we extend it.

Extensions, Delays in Acceptance, Termination or Amendment

        We expressly reserve the right, at any time or various times, to extend the period of time during which the exchange offer is open. We may delay acceptance of any old notes by giving notice of such extension to their holders via a press release or other public announcement. During any such

22


Table of Contents

extensions, all old notes previously tendered will remain subject to the exchange offer, and we may accept them for exchange.

        If we extend the exchange offer, we will notify the exchange agent in writing of any extension. We will notify the registered holders of old notes of any such extension via a press release or other public announcement issued no later than 9:00 a.m., New York City time, on the first business day following the previously scheduled expiration date.

        If any of the conditions described below under "—Conditions to the Exchange Offer" occur, we reserve the right, in our sole discretion:

by giving written notice of such delay, extension or termination to the exchange agent before 9:00 a.m., New York City time, on the first business day following the previously scheduled expiration date. 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 notice thereof via a press release or other public announcement 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.

Conditions to the Exchange Offer

        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.

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

        We expressly reserve the right to amend or terminate the exchange offer, and to reject for exchange any 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 written notice of any extension, amendment, non-acceptance or termination to the exchange agent.

        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 prior to expiration of the exchange offer.

Procedures for Tendering

        In order to participate in the exchange offer, you must properly tender your old notes to the exchange agent as described below. 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 follow carefully the instructions on how to tender your old notes. It is your responsibility to properly tender your old notes. We have the right to waive any defects. However, we are not required to waive defects and neither we nor the exchange agent are 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 contact information is set forth in "Prospectus Summary—The 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 the 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 the transfer, DTC will send an "agent's message" to the exchange agent. The agent's message will state that DTC has received instructions from the participant to tender old notes and that the participant agrees to be bound by the terms of the letter of transmittal.

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

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

Determinations Under the Exchange Offer

        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.

When We Will Issue New Notes

        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 prior to 5:00 p.m., New York City time, on the expiration date:

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

Return of Old Notes Not Accepted or Exchanged

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

Your Representations to Us

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

Withdrawal of Tenders

        Except as otherwise provided in this prospectus, you may withdraw your tender at any time prior to 5:00 p.m., New York City time, on the expiration date. 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.

Fees and Expenses

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

        We have not retained any dealer-manager in connection with the exchange 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:

Transfer Taxes

        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.

Consequences of Failure to Exchange

        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 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.

Accounting Treatment

        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 less any bond discount or plus any bond premium, 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.

Other

        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.

RATIO OF EARNINGS TO FIXED CHARGES

        The following table sets forth our ratio of earnings to fixed charges for the periods presented:

 
  For the years ended December 31,  
 
  2013   2012   2011   2010   2009  

Ratio of earnings to fixed charges(1)

    2.9x     2.1x     4.3x     4.4x     (2)

(1)
For purposes of computing the ratio of earnings to fixed charges, "earnings" consists of pretax income (loss) from continuing operations, excluding income from our equity method investee, plus fixed charges less interest capitalized. "Fixed charges" represents interest incurred, amortization of deferred debt offering costs and that portion of rental expense on operating leases deemed to be the equivalent of interest.

(2)
Due to our net operating loss for the year ended December 31, 2009, the ratio of coverage was less than 1:1. To achieve the ratio coverage of 1:1, we would have needed additional earnings of approximately $256.2 million.

USE OF PROCEEDS

        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 our outstanding indebtedness.

        Laredo Inc. is the borrower under that certain fourth amended and restated revolving credit facility ("senior secured credit facility"), with Wells Fargo Bank, N.A., as administrative agent, that matures November 4, 2018. At March 31, 2014, we had no outstanding borrowings under our senior secured credit facility. Additionally, our senior secured credit facility provides for the issuance of letters of credit, limited in the aggregate to the lesser of $20 million and the total availability thereunder. At March 31, 2014, we had no letters of credit issued. The borrowing base under our senior secured credit facility is $812.5 million with an aggregate of $812.5 million available for borrowings, subject to covenant compliance.

        The borrowing base under our senior secured credit facility is redetermined semi-annually by the lenders, based on, among other things, the financial institutions' evaluation of our oil and natural gas reserves. The next redetermination of our borrowing base is scheduled for no later than May 1, 2014.

        Our obligations under our senior secured credit facility are secured by a first priority lien on substantially all of our oil and natural gas properties as well as a first priority pledge on all ownership interests in our existing and future subsidiaries. Our obligations under the senior secured credit facility are guaranteed by Laredo Inc.'s existing subsidiary and may be guaranteed by any future subsidiaries.

        We have a choice of borrowing at an Adjusted Base Rate or in Eurodollars. Adjusted Base Rate loans will bear interest at the Adjusted Base Rate plus an applicable margin between 0.50% and 1.50% and Eurodollar loans will bear interest at the adjusted LIBOR rate plus an applicable margin between 1.50% and 2.50%. At March 31, 2014, the new applicable margin rates would have been 1.50% for the Adjusted Base Rate advances and 2.50% for the Eurodollar advances. We are also required to pay an annual commitment fee on the unused portion of each bank's commitment ranging from 0.375% to 0.5%.

        Our senior secured credit facility contains various covenants that limit our ability to, among other things, incur indebtedness, make restricted payments, grant liens, consolidate or merge, dispose of certain assets, make certain investments, engage in transactions with affiliates and hedge transactions and make certain acquisitions.

        Our senior secured credit facility also requires us to maintain the following financial ratios as defined therein: (a) consolidated current assets to consolidated current liabilities of not less than 1.00 to 1.00 and (b) consolidated EBITDAX to the sum of (i) consolidated net interest expense plus (ii) letter of credit fees of not less than 2.50 to 1.00.

Existing Senior Notes

2022 Notes

        On April 27, 2012, we completed an offering of $500 million in aggregate principal amount of 73/8% senior unsecured notes due 2022 (the "April 2022 senior notes"). The April 2022 senior notes will mature on May 1, 2022 and bear an interest rate of 73/8% per annum, payable semi-annually, in cash in arrears on May 1 and November 1 of each year, commencing November 1, 2012. The April 2022 senior notes are fully and unconditionally guaranteed on a senior unsecured basis by the subsidiary guarantor and may be guaranteed, jointly and severally, by any future subsidiaries. The net proceeds from the April 2022 senior notes were used to pay in full $280.0 million outstanding under our senior secured credit facility and for general working capital purposes.

        The April 2022 senior notes were issued under, and are governed by, an indenture and supplement thereto, each dated April 27, 2012, among us and Wells Fargo Bank, National Association, as trustee (as further supplemented from time to time, the "2012 Indenture"). The 2012 Indenture contains

Table of Contents

customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of dividends or similar restricted payments, entering into transactions with affiliates and limitations on asset sales. Indebtedness under the April 2022 senior notes may be accelerated in certain circumstances upon an event of default as set forth in the 2012 Indenture.

        We may redeem the April 2022 senior notes, in whole or in part, at any time on or after May 1, 2017, at the redemption prices (expressed as percentages of principal amount) of 103.688% for the 12-month period beginning on May 1, 2017, 102.458% for the 12-month period beginning on May 1, 2018, 101.229% for the 12-month period beginning on May 1, 2019 and 100.000% beginning on May 1, 2020 and at any time thereafter, together with any accrued and unpaid interest to, but not including, the date of redemption. In addition, before May 1, 2017, we may redeem all or any part of the April 2022 senior notes at a redemption price equal to the sum of the principal amount thereof, plus a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date. Furthermore, before May 1, 2015, we may, at any time or from time to time, redeem up to 35% of the aggregate principal amount of the April 2022 senior notes with the net proceeds of a public or private equity offering at a redemption price of 107.375% of the principal amount of the 2022 Notes, plus any accrued and unpaid interest to the date of redemption, if at least 65% of the aggregate principal amount of the April 2022 senior notes issued under the 2012 Indenture remains outstanding immediately after such redemption and the redemption occurs within 180 days of the closing date of such equity offering. We may also be required to make an offer to purchase the April 2022 senior notes upon a change of control triggering event.

2019 Notes

        On January 20, 2011 and October 19, 2011, we issued $350 million principal amount and $200 million principal amount, respectively, of 91/2% senior notes due 2019 (collectively the "2019 senior notes"). The 2019 senior notes will mature on February 15, 2019 and bear an interest rate of 91/2% per annum, payable semi-annually, in cash in arrears on February 15 and August 15 of each year. The 2019 senior notes are fully and unconditionally guaranteed on a senior unsecured basis by the subsidiary guarantor and may be guaranteed, jointly and severally, by any future subsidiaries. The 2019 senior notes were issued under and are governed by an indenture dated January 20, 2011, among us and Wells Fargo Bank, National Association, as trustee (as further supplemented from time to time, the "2019 Indenture"). The 2019 Indenture contains customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of dividends or similar restricted payments, entering into transactions with affiliates and limitations on asset sales. Indebtedness under the 2019 senior notes may be accelerated in certain circumstances upon an event of default as set forth in the indenture governing such notes.

        We may redeem all or a portion of the 2019 senior notes at any time on or after February 15, 2015, on not less than 30 or more than 60 days' prior notice in amount of $2,000 or whole multiples of $1,000 in excess thereof, at the redemption prices (expressed as percentages of principal amount) or 104.750% for the twelve-month period beginning on February 15, 2015, 102.375% for the twelve-month period beginning on February 15, 2016 and 100.000% beginning on February 15, 2017 and at any time thereafter, together with accrued and unpaid interest, if any, thereon to the applicable date of redemption (subject to the rights of holders of record on relevant record dates to receive interest due on an interest payment date).

We may also be required to make an offer to purchase the 2019 senior notes upon a change of control triggering event.

        As of March 31, 2014, we had a total of $1.5 billion of senior unsecured notes outstanding, comprising the April 2022 senior notes, the 2019 senior notes and the old notes.

DESCRIPTION OF THE NOTES

        The Issuer entered into an indenture dated as of January 23, 2014 (the "Indenture"), among the Issuer, the Subsidiary Guarantor and Wells Fargo Bank, National Association, as trustee (the "Trustee"). The old notes were issued, and the new notes will be issued, under the Indenture. On January 23, 2014, we issued $450 million principal amount of notes under the Indenture. References to the "notes" in this "Description of the Notes" include both the outstanding old notes and the new notes offered hereby unless the context otherwise requires. References in this "Description of the Notes" to "Issue Date" mean January 23, 2014, the date on which the old notes were issued. The terms of the notes include those expressly set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The Indenture is unlimited in aggregate principal amount. We may issue an unlimited principal amount of additional notes under the Indenture having identical terms and conditions as the notes (the "Additional Notes"). We will only be permitted to issue such Additional Notes in compliance with the covenant described under the subheading "—Certain Covenants—Incurrence of Indebtedness and Issuance of Disqualified Stock." Any Additional Notes will be part of the same series as the notes that will vote on all matters with the holders of the notes. Unless the context otherwise requires, for all purposes of the Indenture and this "Description of the Notes," references to the notes include the new notes and the old notes and any Additional Notes actually issued.

        This "Description of the Notes" is intended to be a useful overview of the material provisions of the notes and the Indenture. Since this description is only a summary, you should refer to these documents for a complete description of the obligations of the Issuer and the Guarantors and your rights. A copy of the Indenture has been filed as an exhibit to the registration statement of which the prospectus is a part.

        You will find the definitions of capitalized terms used in this "Description of the Notes" under the heading "—Certain Definitions." For purposes of this description, references to "the Company," "the Issuer," "we," "our" and "us" refer only to Laredo Petroleum, Inc., the issuer of the notes, and not to its subsidiary.

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

        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 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 new notes, and the holders of such 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 old notes and the new notes then outstanding.

Brief Description of the notes and the Guarantees

        The new notes will:

31


Table of Contents

        Each guarantee of the new notes will:

        The notes will be structurally subordinated to any existing and future Indebtedness and other liabilities, including claims of trade creditors, of any Subsidiary of the Company that does not guarantee the notes. However, our Restricted Subsidiaries that guarantee or become an obligor in respect of Indebtedness of the Company or any Restricted Subsidiary exceeding $5.0 million will be required to guarantee the notes, pursuant to a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary of the Company's obligations under the notes and the Indenture to the same extent as that set forth in the Indenture, subject to such Restricted Subsidiary ceasing to be a Guarantor when its Guarantee is released in accordance with the terms of the Indenture.

        In the event of a bankruptcy, administrative receivership, composition, insolvency, liquidation or reorganization of any non-guarantor Subsidiary, such Subsidiary will pay the holders of its liabilities, including trade payables, before such Subsidiary will be able to distribute any of its assets to the Company or the Guarantors. As of December 31, 2013, on a pro forma basis after giving effect to the offering of the old notes on January 23, 2014 and the application of the proceeds therefrom, the Company and the Guarantors would have had approximately $1.5 billion of senior unsecured indebtedness outstanding (including the notes) and the Company would be able to draw approximately $812.5 million of secured debt under the Senior Credit Agreement, subject to compliance with financial covenants set forth therein, which debt would be effectively senior to the notes and Guarantees (to the extent of the value of the assets securing such Indebtedness). Subject to the covenants set forth therein, the Indenture permits the Company and the Guarantors to incur additional Indebtedness, including secured Indebtedness.

Principal, Maturity and Interest

        The Company has issued $450.0 million in aggregate principal amount of old notes. The Indenture provides for the issuance of an unlimited amount of additional notes (the "Additional Notes") having identical terms and conditions to the notes in all respects other than the date of issue, the issue price and, at the option of the Company, as to the payment of interest accruing prior to the issue date of such Additional Notes or as to the first payment of interest following the issue date of such Additional

32


Table of Contents

Notes, subject to compliance with the covenants contained in the Indenture, including the covenant described below under the caption "—Certain Covenants—Incurrence of Indebtedness and Issuance of Disqualified Stock." The old notes, the new notes and any Additional Notes will be treated as a single class of securities under the Indenture, including, without limitation, for purposes of waivers, amendments, redemptions and offers to purchase. For purposes of this "Description of the Notes," reference to the notes includes any Additional Notes, unless otherwise indicated. There can be no assurance as to when or whether the Company will issue any such Additional Notes or as to the aggregate principal amount of such Additional Notes. The notes will mature on January 15, 2022.

        Interest on the notes will accrue at the rate of 55/8% per annum and will be payable semiannually in cash on each January 15 and July 15, commencing on the first such date next following the date on which the exchange offer is consummated, to the Holders of record on the immediately preceding January 1 and July 1, as the case may be, but interest payable on any interest payment date on any new note issued in exchange for any old note after a regular record date and prior to such interest payment date will be paid to the holder of record of such old note on such record date. Interest on the notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the Issue Date. Interest will be computed on the basis of a 360-day year comprising twelve 30-day months. The initial payment on the new notes will include all accrued and unpaid interest on the old notes exchanged therefor.

        If an interest payment date falls on a day that is not a business day, the interest payment to be made on such interest payment date will be made, without penalty, on the next succeeding business day with the same force and effect as if made on such interest payment date.

        The new notes issued in exchange for the old notes pursuant to this exchange offer will be considered part of the same series of notes, and all references herein to "notes" include the new notes unless otherwise indicated.

        The principal of and premium, if any, and interest on the notes will be payable, and the notes will be exchangeable and transferable, at the office or agency of the paying agent and registrar maintained for such purposes or, at the option of the Company, payment of interest may be paid by check mailed to the address of the person entitled thereto as such address appears in the security register of Holders. The Company may change the paying agent and registrar without notice to the Holders. The notes will be issued only in registered form without coupons and only in denominations of $2,000 or whole multiples of $1,000 in excess thereof. No service charge will be made for any registration of transfer or exchange or redemption of notes, but the Company may require payment in certain circumstances of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

Method of Payment

        The notes shall be payable as to principal, premium, if any, and interest and additional interest, if any, at the office or agency of the Company maintained for such purpose; provided, however, that (i) payments in respect of the notes represented by the Global Notes (as defined below) (including principal, premium, if any, and interest and additional interest, if any) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company ("DTC") with respect thereto; and (ii) payments in respect of the notes represented by any Certificated Notes (as defined below) (including principal, premium, if any, and interest and additional interest, if any) shall be made (subject (in the case of payments of principal or premium, if any) to surrender of such note at such office or agency): (a) if the Holder thereof has specified by written notice to the Trustee a U.S. dollar account maintained by such Holder with a bank located in the United States of America for such purpose no later than 15 days immediately preceding the relevant payment date (or such later date as the Trustee may accept in its discretion), by wire transfer of immediately available funds to such

33


Table of Contents

account so specified or (b) otherwise, at the option of the Company, by check mailed to the Holder of such note at its address set forth in the security register of Holders.

Paying Agent and Registrar

        The Trustee currently acts as paying agent and registrar. The Company may change any paying agent or registrar without prior notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

Guarantees

        The payment of the principal of and premium, if any, and interest on the notes, when and as the same become due and payable, is guaranteed on a senior unsecured basis pursuant to the guarantee provisions of the indenture, by the Guarantor. On the Issue Date, the Company's sole existing subsidiary, Laredo Midstream Services, LLC, was a Restricted Subsidiary and the only Guarantor, and is referred to in this Description of the Notes as the initial Guarantor. In addition, if (a) any Person becomes a direct or indirect domestic Restricted Subsidiary, (b) any Unrestricted Subsidiary is redesignated as a Restricted Subsidiary, or (c) any other Restricted Subsidiary issues or guarantees any Indebtedness and, in the case of (a), (b) or (c), such Restricted Subsidiary is or becomes a guarantor or obligor in respect of any Indebtedness of the Company or any of its direct or indirect domestic Restricted Subsidiaries in an aggregate principal amount exceeding $5.0 million, the Company shall cause each such Restricted Subsidiary to enter into a supplemental indenture pursuant to which such Restricted Subsidiary shall agree to guarantee the Company's obligations under the notes jointly and severally with any other Guarantors, fully and unconditionally, on a senior unsecured basis. See "—Certain Covenants—Issuances of Guarantees by Restricted Subsidiaries." Non-Guarantor Restricted Subsidiaries and Foreign Subsidiaries will not be required to issue a Guarantee under certain circumstances as described under "—Certain Covenants—Issuances of Guarantees by Restricted Subsidiaries." As of the date of this prospectus, the Company has no Foreign Subsidiaries and no Non-Guarantor Restricted Subsidiaries.

        The obligations of each Guarantor under its Guarantee are limited to the maximum amount that, after giving effect to all other contingent and fixed liabilities of such Guarantor, and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, will result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or state law. See "Risk Factors—Federal and state fraudulent transfer laws may permit a court to void the notes and the guarantees, subordinate claims in respect of the notes and the guarantees and require noteholders to return payments received and, if that occurs, you may not receive any payments on the notes." Each Guarantor that makes a payment or distribution under its Guarantee will be entitled to a contribution from any other non-paying Guarantor in a pro rata amount based on the adjusted net assets of each Guarantor determined in accordance with GAAP.

        Each Guarantor may consolidate with or merge into or sell its assets to the Company or another Restricted Subsidiary that is a Guarantor without limitation, or with or to other Persons upon the terms and conditions set forth in the Indenture. See "—Certain Covenants—Consolidation, Merger and Sale of Assets."

        The Guarantee of a Guarantor will be released automatically:

34


Table of Contents

provided that any such release and discharge pursuant to clause (1), (2), (3), (4), (5), (6) or (7) above shall occur only to the extent that all obligations of such Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which secure any, Indebtedness of the Company and the domestic Restricted Subsidiaries (other than the notes) having an aggregate principal amount in excess of $5.0 million shall also terminate at such time.

Optional Redemption

        On or after January 15, 2017, the Company may redeem all or a portion of the notes, on not less than 30 nor more than 60 days' prior notice and in amounts of $2,000 or whole multiples of $1,000 in excess thereof, at the following redemption prices (expressed as percentages of the principal amount), plus accrued and unpaid interest, if any, thereon, to the applicable redemption date (subject to the rights of Holders of record on relevant record dates to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period beginning on January 15 of the years indicated below:

        In addition, at any time and from time to time prior to January 15, 2017, the Company may use funds in an amount not exceeding the amount of the net cash proceeds of one or more Equity Offerings to redeem up to an aggregate of 35% of the aggregate principal amount of notes issued under the Indenture (including the principal amount of any Additional Notes issued under the Indenture) at a redemption price equal to 105.625% of the aggregate principal amount of the notes redeemed, plus accrued and unpaid interest, if any, to the redemption date (subject to the rights of

Table of Contents

Holders of record on relevant record dates to receive interest due on the relevant interest payment date). At least 65% of the aggregate principal amount of notes (including the principal amount of any Additional Notes issued under the Indenture) must remain outstanding immediately after the occurrence of such redemption. In order to effect this redemption, the Company must complete such redemption no later than 180 days after the closing of the related Equity Offering. Notice of any redemption pursuant to this paragraph may be given prior to the completion of the applicable Equity Offering, and any such redemption or notice may at the Company's discretion be subject to one or more conditions precedent including but not limited to completion of such Equity Offering. If any such conditions do not occur, the Company will provide prompt written notice to the Trustee rescinding such redemption, and such redemption and notice of redemption shall be rescinded and of no force or effect. Upon receipt of such notice, the Trustee will promptly send a copy of such notice to the Holders of the notes to be redeemed in the same manner in which the notice of redemption was given.

        If a Change of Control occurs at any time prior to January 15, 2015, the Company may, at its option, redeem all, but not less than all, of the notes upon not less than 30 nor more than 60 days' prior notice, at a redemption price equal to 110.0% of the principal amount of the notes redeemed, plus accrued and unpaid interest, if any, to the redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). If the Company elects to exercise this redemption right, the Company must do so by mailing a redemption notice to each Holder at its registered address with a copy to the Trustee within 60 days following the Change of Control (or, at the Company's option, prior to such Change of Control but after the transaction giving rise to such Change of Control is publicly announced). Any such redemption may be conditioned upon the Change of Control occurring if the notice is mailed prior to the Change of Control. If the Change of Control does not occur, the Company will provide prompt written notice to the Trustee rescinding such redemption, and such redemption and notice of redemption shall be rescinded and of no force or effect. Upon receipt of such notice, the Trustee will promptly send a copy of such notice to the Holders in the same manner in which the notice of redemption was given. If the Company exercises the Change of Control redemption right, the Company will not be required to make the Change of Control Offer described below under "—Change of Control" unless or until there is a default in payment of the redemption price.

        The notes may also be redeemed, in whole or in part, at any time or from time to time prior to January 15, 2017 at the option of the Company at a redemption price equal to 100% of the principal amount of the notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

        "Applicable Premium" means, with respect to any note on any applicable redemption date, the greater of: (1) 1.0% of the principal amount of such note; and (2) the excess, if any, of: (a) the present value at such redemption date of (i) the redemption price of such note at January 15, 2017 (such redemption price being set forth in the table appearing above) plus (ii) all required interest payments (excluding accrued and unpaid interest to such redemption date) due on such note through January 15, 2017, computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over (b) the principal amount of such note.

        "Treasury Rate" means, as of any redemption date, the weekly average yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two business days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) equal to the period from the redemption date to January 15, 2017; provided, however, that if the period from the redemption date to January 15, 2017 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to

36


Table of Contents

the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities that have a constant maturity closest to and greater than the period from the redemption date to January 15, 2017 and the United States Treasury securities that have a constant maturity closest to and less than the period from the redemption date to January 15, 2017 for which such yields are given, except that if the period from the redemption date to January 15, 2017 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used. The Company will (1) calculate the Treasury Rate on the third business day preceding the applicable redemption date and (2) prior to such redemption date, deliver to the Trustee an officers' certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable detail.

        Notices of optional redemption will be mailed by first class mail at least 30 but no more than 60 days before the redemption date to each Holder of notes to be redeemed at its registered address, except that optional redemption notices may be mailed more than 60 days prior to a redemption date in connection with a legal or covenant defeasance of the notes or a satisfaction and discharge of the Indenture.

        If less than all of the notes are to be redeemed, the Trustee shall select the notes to be redeemed not more than 60 days prior to the redemption date, or otherwise in compliance with the requirements of the principal national security exchange, if any, on which the notes are listed, or if the notes are not so listed, on a pro rata basis (or, in the case of Global Notes, on as nearly a pro rata basis as is practicable, subject to the procedures of DTC or any other depositary), by lot or by any other method the Trustee shall deem fair and reasonable. Notes redeemed in part must be redeemed only in amounts of $2,000 or whole multiples of $1,000 in excess thereof (subject to the procedures of DTC or any other depositary). Redemption pursuant to the provisions relating to an Equity Offering must be made on a pro rata basis or on as nearly a pro rata basis as practicable (subject to the procedures of DTC or any other depositary).

        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 replacement note in principal amount equal to the unredeemed portion of the old note will be issued in the name of the Holder upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption, unless the redemption is subject to a condition precedent that is not satisfied or waived. On and after the redemption date, interest ceases to accrue on notes or portions of notes called for redemption, unless the Company defaults in making the redemption payment.

        The notice of redemption with respect to the redemption described in the fourth paragraph under this "—Optional Redemption" need not set forth the Applicable Premium but only the manner of calculation thereof. The Company will notify the Trustee of the Applicable Premium with respect to any redemption promptly after the calculation thereof, and the Trustee shall not be responsible for such calculation. Any redemption or notice of redemption may, at the Company's discretion, be subject to one or more conditions precedent and, in the case of redemption with the net proceeds of an Equity Offering, be given prior to the completion of the related Equity Offering.

Open Market Purchases; No Mandatory Redemption or Sinking Fund

        In addition to the Company's right to redeem the notes as set forth above, the Company or its Affiliates may from time to time purchase the notes in open-market transactions, privately negotiated transactions, tender offers, exchange offers or otherwise, upon such terms and at such prices as the Company or its Affiliates may determine, which may be for cash or other consideration.

        The Company is not required to make mandatory redemption or sinking fund payments with respect to the notes.

Change of Control

        If a Change of Control occurs, unless the Company has given (or if a Change of Control occurs prior to January 15, 2015, within 60 days thereafter will have given) notice of redemption of all the notes as described under "—Optional Redemption," each Holder will have the right to require that the Company purchase all or any part (in amounts of $2,000 or whole multiples of $1,000 in excess thereof) of such Holder's notes pursuant to an offer (the "Change of Control Offer") on the terms set forth in the Indenture. In the Change of Control Offer, the Company will offer to purchase all of the notes, at a purchase price (the "Change of Control Purchase Price") in cash in an amount equal to 101% of the principal amount of such notes, plus accrued and unpaid interest, if any, to the date of purchase (the "Change of Control Purchase Date") (subject to the rights of Holders of record on relevant record dates to receive interest due on the relevant interest payment date).

        Within 30 days after any Change of Control or, at the Company's option, prior to such Change of Control but after it is publicly announced, unless the Company has given (or if a Change of Control occurs prior to January 15, 2015, within 60 days thereafter will have given) notice of redemption of all the notes as described under "—Optional Redemption," the Company must notify the Trustee and give written notice of the Change of Control to each Holder, by first-class mail, postage prepaid, at the address appearing for such Holder in the security register or otherwise in accordance with the procedures of DTC. The notice must state, among other things,

        Holders electing to have a note purchased pursuant to a Change of Control Offer will be required to surrender the note to the paying agent for the notes at the address specified in the notice prior to the close of business on the third business day prior to the Change of Control Purchase Date. If the Change of Control Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Holder of record at the close of business on the record date, and no additional interest will be payable to Holders who tender pursuant to the Change of Control Offer.

        Any Change of Control Offer that is made prior to the occurrence of a Change of Control may at the Company's discretion be subject to one or more conditions precedent, including but not limited to the occurrence of a Change of Control.

        If a Change of Control Offer is made, the Company may not have available funds sufficient to pay the Change of Control Purchase Price for all of the notes that might be delivered by Holders seeking to accept the Change of Control Offer. The failure of the Company to make or consummate the

38


Table of Contents

Change of Control Offer or pay the Change of Control Purchase Price when due may give the Trustee and the Holders rights described under "—Events of Default."

        The indentures governing the Existing Senior Notes provide that upon the occurrence of certain change-of-control events, each holder of the Existing Senior Notes will have the right to require the Company to purchase all or any part of such holder's Existing Senior Notes. In such event, the Company may not have available funds sufficient to pay the aggregate purchase price of the Existing Senior Notes delivered by holders exercising such right. The failure of the Company to purchase the delivered Existing Senior Notes may result in the occurrence of a default under the indentures governing the Existing Senior Notes.

        The Senior Credit Agreement provides that certain change-of-control events with respect to the Company would constitute a default thereunder, which could obligate the Company to repay amounts outstanding under the Senior Credit Agreement upon an acceleration of the Indebtedness issued thereunder. A default under the Senior Credit Agreement would result in a default under the Indenture if the lenders holding a certain percentage of the commitments thereunder accelerate the debt under the Senior Credit Agreement. Any future credit agreements or agreements relating to other indebtedness to which the Company becomes a party may contain similar restrictions and provisions. In the event a Change of Control occurs at a time when the Company is prohibited from purchasing notes, the Company could seek the consent of the lenders holding a certain percentage of the commitments under those agreements to the purchase of the notes or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such a consent or repay such borrowings, the Company will remain prohibited from purchasing notes. In such case, the Company's purchase of tendered notes may result in an Event of Default under the Indenture if the lenders under its other debt agreements, including the Senior Credit Agreement, accelerate Indebtedness under those agreements in an aggregate principal amount in excess of $20.0 million. See "Risk Factors—We may not be able to repurchase the notes in certain circumstances."

        The definition of Change of Control includes a phrase relating to the sale, assignment, conveyance, transfer, lease or other disposition, in one or a series of related transactions, of "all or substantially all" of the assets of the Company and the Restricted Subsidiaries, taken as a whole. Thus, only asset dispositions constituting a "series of related transactions" are aggregated in determining whether a "change of control" arising from the sale of "substantially all" of the assets has taken place. Moreover, the term "all or substantially all," as used in the definition of Change of Control, has not been interpreted under New York law (which is the governing law of the Indenture) to represent a specific quantitative test. Therefore, if Holders elected to exercise their right to require the Company to repurchase their notes under the Indenture as a result of a sale, assignment, conveyance, transfer, lease or other disposition of less than all of the assets of the Company and the Restricted Subsidiaries taken as a whole and the Company elected to contest such election, it is not clear how a court applying New York law would interpret the phrase.

        Recent Delaware case law has raised the possibility that the obligation of a Delaware corporation to make a change of control repurchase offer for its debt that arises as a result of a failure of such corporation to have "continuing directors" compose a majority of its Board of Directors may be unenforceable on public policy grounds under Delaware law to the extent such obligation involves a breach of fiduciary duty. Additionally, recent Delaware case law suggests that, in the event that incumbent directors are replaced as a result of a contested election, issuers of debt may nevertheless avoid triggering a change of control under a clause similar to clause (2) of the definition of "Change of Control" under the caption "Certain Definitions," if the outgoing directors were to approve the new directors for the purpose of such change of control clause.

Table of Contents

        The existence of a Holder's right to require the Company to repurchase such Holder's notes upon a Change of Control may deter a third party from acquiring the Company in a transaction that constitutes a Change of Control.

        The provisions of the Indenture do not afford Holders the right to require the Company to repurchase the notes in the event of a highly leveraged transaction or certain transactions with management or Affiliates of the Company, including a reorganization, restructuring, merger or similar transaction (including, in certain circumstances, an acquisition of the Company by management or its Affiliates) involving the Company that may adversely affect Holders, if such transaction is not a transaction defined as a Change of Control. A transaction involving the management or Affiliates of the Company, or a transaction involving a recapitalization of the Company, will result in a Change of Control if it is the type of transaction specified within such definition.

        The Company will comply with the applicable tender offer rules, including Rule 14e-1 under the Exchange Act, and any other applicable securities laws or regulations in connection with a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the "Change of Control" provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the "Change of Control" provisions of the Indenture by virtue thereof.

        The Company will not be required to make a Change of Control Offer under the following circumstances: (1) upon a Change of Control, if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements described in the Indenture applicable to a Change of Control Offer made by the Company and purchases all notes validly tendered and not withdrawn under such Change of Control Offer; or (2) if notice of redemption for 100% of the aggregate principal amount of the outstanding notes has been given (or, if a Change of Control occurs prior to January 15, 2015, within 60 days thereafter will have been given), pursuant to the Indenture as described under "—Optional Redemption," unless and until there is a default in payment of the applicable redemption price.

        In the event that upon consummation of a Change of Control Offer less than 10% of the aggregate principal amount of the notes (including Additional Notes) that were originally issued are held by Holders other than the Company or Affiliates thereof, the Company will have the right, upon not less than 30 nor more than 60 days' prior notice and 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 101% of the aggregate principal amount of the notes redeemed plus accrued and unpaid interest, if any, thereon to the date of redemption, subject to the right of the Holders of record on relevant record dates to receive interest due on the relevant interest payment date.

        The provisions under the Indenture related to the Company's obligation to make an offer to repurchase the notes as a result of a Change of Control may be waived or modified or terminated with the consent of the Holders of a majority in principal amount of the notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the notes) prior to the occurrence of such Change of Control.

Certain Covenants

        If at any time (a) the notes are rated at least Baa3 by Moody's and at least BBB- by S&P (or, if either such entity ceases to rate the notes for reasons outside of the control of the Company, at least the equivalent investment grade credit rating from any other "nationally recognized statistical rating organization" within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the

40


Table of Contents

Company as a replacement agency); and (b) at such time no Event of Default has occurred and is continuing then, beginning on that day and each day thereafter until a Reversion Date, if any (as described in the second succeeding paragraph), the covenants specifically listed under the following captions in this prospectus (the "Suspended Covenants") will be suspended:

        During any period that the foregoing covenants have been suspended (each such period, a "Suspension Period"), the Company's Board of Directors may not designate any of its Restricted Subsidiaries as Unrestricted Subsidiaries pursuant to the covenant described under "—Unrestricted Subsidiaries."

        Notwithstanding the foregoing, if the rating assigned by either such rating agency should subsequently decline to below Baa3 or BBB-, respectively, the foregoing covenants will be reinstituted as of and from the date of such rating decline (such date, a "Reversion Date").

        For purposes of calculating the amount available to be made as Restricted Payments under clause (a)(3) of the first paragraph of the covenant described under "—Restricted Payments," calculations under that clause will be made with reference to the date of the Restricted Payment, as set forth in that clause. Accordingly (x) Restricted Payments made during the Suspension Period that would not otherwise be permitted pursuant to any of clauses (b)(1) through (b)(14) of the covenant described under "—Restricted Payments" will reduce the amount available to be made as Restricted Payments under clause (a)(3) of the first paragraph of such covenant; provided, however, that the amount available to be made as a Restricted Payment shall not be reduced to below zero solely as a result of such Restricted Payments but may be reduced to below zero as a result of negative cumulative Consolidated Net Income during the Suspension Period for purposes of clause (a)(3)(A) of such covenant and (y) the items specified in clauses (a)(3)(A) through (F) of such covenant that occur during the Suspension Period will increase the amount available to be made as Restricted Payments under clause (a)(3) of such covenant. For purposes of the covenant described under "—Asset Sales," on each Reversion Date, the unutilized Excess Proceeds will be reset to zero. No Default or Event of Default will be deemed to have occurred or exist on a Reversion Date (or thereafter) under any Suspended Covenant, solely as a result of, or as a result of the continued existence on or after a Reversion Date of facts and circumstances arising from, any actions taken by the Company or any Restricted Subsidiaries thereof, or events occurring, or performance on or after a Reversion Date of any obligations arising from transactions which occurred, during a Suspension Period.

        The Indenture contains covenants including, among others, the following:

        (a)   The Company will not, and will not cause or permit any Restricted Subsidiary to, create, issue, incur, assume, guarantee or otherwise in any manner become directly or indirectly liable for the payment of or otherwise incur, contingently or otherwise (collectively, "incur"), any Indebtedness (including any Acquired Debt and the issuance of Disqualified Stock or the issuance of Preferred Stock by a Restricted Subsidiary), unless such Indebtedness is incurred by the Company or any Guarantor and, in each case, after giving pro forma effect to such incurrence and the receipt and application of the proceeds therefrom, the Company's Consolidated Fixed Charge Coverage Ratio for the most recent four full fiscal quarters for which financial statements are available immediately preceding the incurrence of such Indebtedness taken as one period would be equal to or greater than 2.25 to 1.0.

        (b)   Notwithstanding the foregoing, the Company and, to the extent specifically set forth below, the Restricted Subsidiaries may incur each and all of the following (collectively, "Permitted Debt"):

42


Table of Contents

        For purposes of determining compliance with this covenant, in the event that an item of Indebtedness meets the criteria of more than one of the categories of "Permitted Debt" or is permitted to be incurred pursuant to the first paragraph of this covenant, the Company in its sole discretion may classify or reclassify (or later classify or reclassify) in whole or in part such item of Indebtedness in any manner (including by dividing and classifying such item of Indebtedness in more than one type of Indebtedness permitted under this covenant) that complies with this covenant; provided that

43


Table of Contents

Indebtedness under the Senior Credit Agreement, if any, which is in existence on the Issue Date shall be considered incurred under clause (1) of the second paragraph of this covenant, subject to any subsequent classification or reclassification or division permitted pursuant to this paragraph.

        Indebtedness permitted by this covenant need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such Indebtedness.

        Accrual of interest, accretion or amortization of original issue discount or accretion of principal as to a security issued at a discount and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the accretion or payment of dividends on any Disqualified Stock or Preferred Stock in the form of additional shares of the same class of Disqualified Stock or Preferred Stock, the obligation to pay a premium in respect of Indebtedness arising in connection with the issuance of a notice of redemption or making of a mandatory offer to purchase such Indebtedness, and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of SFAS 133), each will not be deemed to be an incurrence of Indebtedness for purposes of this covenant; provided, in each such case, that the amount thereof as accrued shall be included as required in the calculation of the Consolidated Fixed Charge Coverage Ratio of the Company.

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

        For purposes of determining any particular amount of Indebtedness under this covenant, (i) guarantees of, or obligations in respect of letters of credit relating to, Indebtedness otherwise included in the determination of such amount shall not also be included and (ii) if obligations in respect of letters of credit are incurred pursuant to a Credit Facility and are being treated as incurred pursuant to clause (1) of the definition of "Permitted Debt" and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included. If Indebtedness is secured by a letter of credit that serves only to secure such Indebtedness, then the total amount deemed incurred shall be equal to the greater of (x) the principal of such Indebtedness and (y) the amount that may be drawn under such letter of credit.

        For purposes of the Indenture, no Indebtedness will be deemed to be subordinate or junior in right of payment to other Indebtedness solely by virtue of not having the benefit of a Lien on assets, or guarantee of a Person, that benefits the other Indebtedness or having the benefit of such a Lien or guarantee ranking subordinate or junior to a Lien or guarantee benefiting the other Indebtedness.

        In determining whether any Restricted Payment (or payment or other transaction that, except for being a Permitted Payment, would constitute a Restricted Payment) is permitted by the foregoing covenant, the Company may allocate or re-allocate all or any portion of such Restricted Payment or other such transaction among clauses (1) through (14) of the preceding paragraph (b) or among such clauses and paragraph (a) of this covenant, including the second set of clauses (1), (2) and (3) thereof; provided that at the time of such allocation or re-allocation all such Restricted Payments and such other transactions or allocated portions thereof, all outstanding prior Restricted Payments and such other transactions, would be permitted under the various provisions of the foregoing covenant. The amount of all Restricted Payments and other such transactions (other than cash) shall be the Fair Market Value on the date of the transfer, incurrence or issuance of such non-cash Restricted Payment or other such transaction.

        A contribution or sale will be deemed to be "substantially concurrent" if the related purchase, repurchase, redemption, defeasance, satisfaction and discharge, retirement or other acquisition for value or payment of principal occurs within 90 days before or after such contribution or sale.

        The Company will not, and will not cause or permit any Restricted Subsidiary to, directly or indirectly, create or incur, in order to secure any Indebtedness, any Lien of any kind, other than Permitted Liens, upon any property or assets (including any intercompany notes) of the Company or any Restricted Subsidiary owned on the Issue Date or acquired after the Issue Date, or assign or convey, in order to secure any Indebtedness, any right to receive any income or profits therefrom, other than Permitted Liens, unless the notes (or a Guarantee in the case of Liens of a Guarantor) are directly secured equally and ratably with (or, in the case of Subordinated Indebtedness, prior or senior thereto, with the same relative priority as the notes shall have with respect to such Subordinated Indebtedness) the Indebtedness for so long as such Indebtedness is secured by such Lien.

        Notwithstanding the foregoing, any Lien securing the notes or a Guarantee granted pursuant to the immediately preceding paragraph shall be automatically and unconditionally released and discharged upon:

        (a)   The Company will not, and will not cause or permit any Restricted Subsidiary to, consummate any Asset Sale unless (i) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets and property subject to such Asset Sale (such Fair Market Value to be determined on the date of contractually agreeing to effect such Asset Sale) and (ii) (A) at least 75% of the consideration paid to the Company or such Restricted Subsidiary from such Asset Sale and all other Asset Sales since the Issue Date, on a cumulative basis, is in the form of cash, Cash Equivalents, Liquid Securities, Exchanged Properties (including pursuant to Asset Swaps) or the assumption by the acquiring Person of Indebtedness or other liabilities of the Company or a Restricted Subsidiary (other than liabilities of the Company or a Restricted Subsidiary that are by their terms subordinated to the notes) as a result of which the Company and the remaining Restricted Subsidiaries are no longer liable for such liabilities (or in lieu of such absence of liability, the acquiring Person or its parent company agrees to indemnify and hold the Company or such Restricted Subsidiary harmless from and against any loss, liability or

cost in respect of such assumed liabilities accompanied by the posting of a letter of credit (issued by a commercial bank that has an Investment Grade Rating) in favor of the Company or such Restricted Subsidiary for the full amount of such liabilities and for so long as such liabilities remain outstanding unless such indemnifying party (or its long term debt securities) shall have an Investment Grade Rating (with no indication of a negative outlook or credit watch with negative implications, in any case, that contemplates such indemnifying party (or its long term debt securities) failing to have an Investment Grade Rating) at the time the indemnity is entered into) ("Permitted Consideration") or (B) the Fair Market Value of all forms of such consideration other than Permitted Consideration since the Issue Date does not exceed in the aggregate 5% of the Adjusted Consolidated Net Tangible Assets of the Company determined at the time such Asset Sale is made.

        (b)   During the 365 days after the receipt by the Company or a Restricted Subsidiary of Net Available Cash from an Asset Sale, such Net Available Cash may be applied by the Company or such Restricted Subsidiary, to the extent the Company or such Restricted Subsidiary elects (or is required by the terms of any Pari Passu Indebtedness of the Company or a Restricted Subsidiary), to:

        The requirement of clause (b)(2) above shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or investment referred to therein is entered into by the Company or any Restricted Subsidiary within the time period specified in this paragraph (b) and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

        Pending the final application of any such Net Available Cash, the Company may temporarily reduce Indebtedness under any Credit Facility or otherwise expend or invest such Net Available Cash in any manner that is not prohibited by the Indenture.

        (c)   Any Net Available Cash from an Asset Sale not applied in accordance with paragraph (b) above within 365 days from the date of such Asset Sale shall constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $25.0 million, the Company will be required to make an offer to purchase notes having an aggregate principal amount equal to the aggregate amount of Excess Proceeds (the "Prepayment Offer") at a purchase price equal to 100% of the principal amount of such notes plus accrued and unpaid interest, if any, to the Asset Sale Purchase Date (as defined in paragraph (d) below) in accordance with the procedures (including prorating in the event of over

subscription) set forth in the Indenture, but, if the terms of any Pari Passu Indebtedness require that a Pari Passu Offer be made contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be prorated between the Prepayment Offer and such Pari Passu Offer in accordance with the aggregate outstanding principal amounts of the notes and such Pari Passu Indebtedness (based on principal amounts of notes and Pari Passu Indebtedness (or, in the case of Pari Passu Indebtedness issued with significant original issue discount, based on the accreted value thereof) tendered), and the aggregate principal amount of notes for which the Prepayment Offer is made shall be reduced accordingly. If the aggregate principal amount of notes tendered by Holders thereof exceeds the amount of available Excess Proceeds, then such Excess Proceeds will be allocated pro rata according to the principal amount of the notes tendered and the Trustee will select the notes to be purchased in accordance with the Indenture on a pro rata basis (or in the case of Global Notes, on as nearly a pro rata basis as is practicable, subject to the procedures of DTC or any other depositary), by lot or in accordance with any other method the Trustee considers fair and reasonable and in minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. To the extent that any portion of the amount of Excess Proceeds remains after compliance with the second sentence of this paragraph (c) and provided that all Holders of notes have been given the opportunity to tender their notes for purchase as described in paragraph (d) below in accordance with the Indenture, the Company or the Restricted Subsidiaries may use such remaining amount for purposes permitted by the Indenture and the amount of Excess Proceeds will be reset to zero. The Company may satisfy the foregoing obligation with respect to any Excess Proceeds by making a Prepayment Offer prior to the expiration of the relevant 365 day period or with respect to Excess Proceeds of $25.0 million or less.

        (d)   Within 30 days after the 365th day following the date of an Asset Sale, the Company shall, if it is obligated to make a Prepayment Offer pursuant to paragraph (c) above, send a written Prepayment Offer notice, by first-class mail or otherwise in accordance with the procedures of DTC, to the Holders (the "Prepayment Offer Notice"), with a copy to the Trustee, accompanied by such information regarding the Company and its Subsidiaries as the Company believes will enable such Holders to make an informed decision with respect to the Prepayment Offer. The Prepayment Offer Notice will state, among other things:

Table of Contents

        (e)   The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Prepayment Offer, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described above by virtue thereof.

        The provisions under the Indenture relative to the Company's obligation to make an offer to repurchase the notes as a result of an Asset Sale may be waived or modified with the written consent of a majority in principal amount of the outstanding notes (including Additional Notes) until the Prepayment Offer is required to be made.

        If the Asset Sale Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Holder of record as of the close of business on such interest record date, and no additional interest will be paid to the Holder who tenders notes pursuant to the Prepayment Offer.

        The Company will provide to the Trustee, on or prior to the 30th day after the date that any Restricted Subsidiary (which is not a Guarantor) becomes a guarantor or obligor in respect of any Indebtedness of the Company or any Restricted Subsidiary in an aggregate principal amount exceeding $5.0 million, a supplemental indenture to the Indenture, executed by such Restricted Subsidiary, providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary of the Company's obligations under the notes and the Indenture to the same extent as that set forth in the Indenture, subject to such Restricted Subsidiary ceasing to be a Guarantor when its Guarantee is released in accordance with the terms of the Indenture.

        Notwithstanding the foregoing (i) no Foreign Subsidiary shall be required to execute any such supplemental indenture unless such Foreign Subsidiary has guaranteed (or is otherwise an obligor of) other Indebtedness (including Indebtedness under a Credit Facility) of the Company or a Restricted Subsidiary that is not a Foreign Subsidiary in an aggregate principal amount exceeding $5.0 million, and (ii) no Restricted Subsidiary shall be required to execute any such supplemental indenture if the Consolidated Net Worth of such Restricted Subsidiary, together with the Consolidated Net Worth of all other Non-Guarantor Restricted Subsidiaries, as of such date, does not exceed in the aggregate $5.0 million. To the extent the collective Consolidated Net Worth of the Non-Guarantor Restricted Subsidiaries, as of the date of the creation of, acquisition of or Investment in a Non-Guarantor Restricted Subsidiary, exceeds $5.0 million, the Company shall cause, within 30 days after such date, one or more of such Non-Guarantor Restricted Subsidiaries to similarly execute and deliver to the Trustee a supplemental indenture to the Indenture providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary or Restricted Subsidiaries of the Company's obligations under the notes and the Indenture to the same extent as that set forth in the Indenture, such that the collective Consolidated Net Worth of all remaining Non-Guarantor Restricted Subsidiaries does not exceed $5.0 million.

        (a)   The Company will not, and will not cause or permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause to come into existence or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

        The Company will not, and will not cause or permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction; provided, that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if:

        The Board of Directors of the Company may designate after the Issue Date any of the Company's Subsidiaries as an Unrestricted Subsidiary under the Indenture (a "Designation") only if:

57


Table of Contents

        In the event of any such Designation, the Company shall be deemed, for all purposes of the Indenture, to have made an Investment equal to the Designation Amount that, as designated by the Company, constitutes a Restricted Payment pursuant to paragraph (a) of the covenant described under "—Restricted Payments" or a Permitted Payment or Permitted Investment.

        The Indenture also provides that the Company shall not and shall not cause or permit any Restricted Subsidiary to at any time:

        For purposes of the foregoing, the Designation of a Subsidiary of the Company as an Unrestricted Subsidiary shall be deemed to be the Designation of all of the Subsidiaries of such Subsidiary as Unrestricted Subsidiaries. Unless so designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of the Company will be classified as a Restricted Subsidiary.

        The Company may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a "Revocation") if:

        All Designations and Revocations must be evidenced by a resolution of the Board of Directors of the Company delivered to the Trustee certifying compliance with the foregoing provisions of this covenant.

Table of Contents

        The Indenture provides that none of the Company nor any Restricted Subsidiary will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the notes unless such consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

        The Indenture provides that, whether or not required by the rules and regulations of the Commission, so long as any notes are outstanding, the Company will furnish to Holders or cause the Trustee to furnish to the Holders or file with the Commission for public availability

provided, however, that, in the case of clause (1) or (2), if the last day of any such time period is not a business day, such information will be due on the next succeeding business day. All such information will be prepared in all material respects in accordance with all of the rules and regulations of the Commission applicable to such information.

        If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries (other than Unrestricted Subsidiaries that, when taken together with all other Unrestricted Subsidiaries, are "minor" within the meaning of Rule 3-10 of Regulation S-X, substituting 5% for 3% where applicable), then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, or in Management's Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and the Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries.

        This covenant does not impose any duty on the Company under the Sarbanes-Oxley Act of 2002 and the related Commission rules that would not otherwise be applicable.

        The Company has agreed that, for so long as any of the notes remain outstanding and constitute "restricted securities" under Rule 144 and the Company is not subject to Section 13 or 15(d) of the Exchange Act, it will furnish to the Holders and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

        The Company will be deemed to have furnished to the Holders and to prospective investors the information referred to in clauses (1) and (2) of the first paragraph of this covenant or the information referred to in the fourth paragraph of this covenant if the Company has posted such reports or information on the Company Website with access to current and prospective investors. For purposes of this covenant, the term "Company Website" means the collection of web pages that may be accessed

        Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on officers' certificates).

        The Company will not, in any Transaction, (x) consolidate with or merge with or into any other Person or (y) sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person, or (in the case of clause (y)) permit any of the Restricted Subsidiaries to enter into any Transaction, if such Transaction, in the aggregate, would result in a sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of the Company and the Restricted Subsidiaries on a Consolidated basis to any other Person (other than the Company or one or more Restricted Subsidiaries), unless at the time and after giving effect thereto:

Table of Contents

        Except for any Guarantor whose Guarantee is to be released in accordance with the Indenture in connection with a transaction complying with the provisions of the Indenture as provided under the fourth paragraph under "—Guarantees," each Guarantor will not, and the Company will not permit a Guarantor to, in a Transaction, (x) consolidate with or merge with or into any other Person (other than the Company or any other Guarantor) or (y) sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person (other than the Company or any other Guarantor), unless at the time and after giving effect thereto:

provided that this paragraph shall not apply to any Guarantor whose Guarantee of the notes is unconditionally released and discharged in accordance with the Indenture.

61


Table of Contents

        In the event of any Transaction described in and complying with the conditions listed in the two immediately preceding paragraphs in which the Company or any Guarantor, as the case may be, is not the continuing Person, the successor Person formed or remaining or to which such transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company or such Guarantor, as the case may be, and (except in the case of a lease) the Company or such Guarantor, as the case may be, shall be discharged and released from all obligations and covenants under the Indenture and the notes or its Guarantee, as the case may be.

        Notwithstanding the foregoing, the Company or any Guarantor may merge with an Affiliate incorporated or organized solely for the purpose of reincorporating or reorganizing the Company or Guarantor in another jurisdiction to realize tax or other benefits or converting the Company or any Guarantor to an entity that is, or is taxable for federal income tax purposes as, a corporation or a combination of the foregoing.

        An assumption of the Company's obligations under the notes and the Indenture by such successor Person, the addition of a co-obligor under the notes and the Indenture or an assumption of a Guarantor's obligations under its Guarantee by such successor Person might be deemed for United States federal income tax purposes to be an exchange of the notes for new notes by the beneficial owners thereof, resulting in recognition of gain or loss for such purposes and possibly other adverse tax consequences to such beneficial owners. Beneficial owners of the notes should consult their own tax advisors regarding the tax consequences of any such assumption or addition of a co-obligor under the notes.

Events of Default

        Each of the following is an "Event of Default":

62


Table of Contents

        If an Event of Default (other than as specified in clause (8) of the prior paragraph with respect to the Company) shall occur and be continuing with respect to the Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of the notes then outstanding may declare all unpaid principal of, premium, if any, and accrued interest on all notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders) and upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. If an Event of Default specified in clause (8) of the prior paragraph with respect to the Company occurs and is continuing, then all the notes shall ipso facto become due and payable immediately in an amount equal to the principal amount of the notes, together with accrued and unpaid interest, if any, to the date the notes become due and payable, without any declaration or other act on the part of the Trustee or any Holder. Thereupon, the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders by appropriate judicial proceedings.

        After a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of notes outstanding by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

63


Table of Contents

        No such rescission shall affect any subsequent default or impair any right consequent thereon.

        The Holders of a majority in aggregate principal amount of the notes outstanding may on behalf of the Holders of all outstanding notes waive any past default or Event of Default under the Indenture and its consequences, except a default or Event of Default (1) in the payment of the principal of, premium, if any, or interest on any note (which may only be waived with the consent of each Holder of notes affected) or (2) in respect of a covenant or provision which under the Indenture cannot be modified or amended without the consent of the Holder of each note affected by such modification or amendment.

        If an Event of Default specified in clause (5) above shall have occurred and be continuing, such Event of Default and any consequential acceleration shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default shall have been repaid or (ii) if the default relating to such Indebtedness is waived or cured and if such Indebtedness shall have been accelerated, the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness.

        No Holder has any right to institute any proceedings with respect to the Indenture or any remedy thereunder, unless such Holder gives to the Trustee written notice of a continuing Event of Default, the Holders of at least 25% in aggregate principal amount of the outstanding notes have made written request, and offered satisfactory indemnity to, the Trustee to institute such proceeding as Trustee under the notes and the Indenture, the Trustee has failed to institute such proceeding within 60 days after receipt of such notice and the Trustee, within such 60-day period, has not received directions inconsistent with such written request by Holders of a majority in aggregate principal amount of the outstanding notes. Such limitations do not, however, apply to a suit instituted by a Holder for the enforcement of the payment of the principal of, premium, if any, or interest on such note on or after the respective due dates expressed in such note.

        The Company is required to notify the Trustee in writing within 30 days after it becomes aware of the occurrence and continuance of any Default or Event of Default, unless such Default or Event of Default has been cured before the end of the 30-day period. The Company is required to deliver to the Trustee, on or before a date not more than 120 days after the end of each fiscal year, a written certificate as to compliance with the Indenture, including whether or not any Default has occurred. The Trustee is under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request or direction of any of the Holders unless such Holders offer to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred thereby.

No Personal Liability of Directors, Officers, Employees, Limited Partners and Stockholders

        No director, officer, employee, member, limited partner or stockholder of the Company or any Restricted Subsidiary, as such, will have any liability for any obligations of the Company or the Restricted Subsidiaries under the notes, the Indenture or the Guarantees to which they are a party, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a note waives and releases all such liability. The waiver and release are part of the

64


Table of Contents

consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Defeasance or Covenant Defeasance of Indenture

        The Company may, at its option and at any time, elect to have the obligations of the Company, any Guarantor and any other obligor upon the notes and the Guarantees discharged with respect to the outstanding notes ("defeasance"). Such defeasance means that the Company, any such Guarantor and any other obligor under the Indenture and the Guarantees shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding notes and the Guarantees, except for

        In addition, the Company may, at its option and at any time, elect to have the obligations of the Company and any Guarantor released with respect to their obligations under "—Change of Control" and under all of the covenants that are described under "—Certain Covenants" (other than the covenant described in the first paragraph under "—Certain Covenants—Consolidation, Merger and Sale of Assets," except to the extent described below) and the operation of clauses (3) through (7) under "—Events of Default" and the limitations described in clause (4) of the first paragraph under "—Certain Covenants—Consolidation, Merger and Sale of Assets" ("covenant defeasance") and thereafter any omission to comply with such obligations shall not constitute a Default or an Event of Default with respect to the notes. In the event covenant defeasance occurs, certain events (not including non-payment, bankruptcy and insolvency events) described under "—Events of Default" will no longer constitute an Event of Default with respect to the notes.

        In order to exercise either defeasance or covenant defeasance,

Amendments and Waivers

        Modifications, waivers and amendments of the Indenture may be made by the Company, each Guarantor, if any, any other obligor under the notes, and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the notes then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes); provided that no such modification, waiver or amendment may, without the consent of the Holder of each outstanding note affected thereby:

67


Table of Contents

        Notwithstanding the foregoing, without the consent of any Holders, the Company, any Guarantor, any other obligor under the notes and the Trustee may modify, supplement or amend the Indenture:

68


Table of Contents

        The Holders of a majority in aggregate principal amount of the notes outstanding may waive compliance with certain restrictive covenants and provisions of the Indenture, except in the case of the matters specified in the first paragraph under this caption "Amendments and Waivers."

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

Transfer and Exchange

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

        The registered holder of a note will be treated as the owner of it for all purposes.

Governing Law

        The Indenture, the notes and any Guarantee will be governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustee

        Wells Fargo Bank, National Association, the Trustee under the Indenture, is the agent and registrar for the notes.

        The Indenture contains certain limitations provided in the Trust Indenture Act on the rights of the Trustee, should it become a creditor of the Company or any Guarantor, to obtain payment of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions with the Company or any Guarantor; provided that if it acquires any conflicting interest as defined in the Trust Indenture Act it must either eliminate such conflict or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and the Indenture.

        The Holders of a majority in principal amount of the then outstanding notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions and the rights of the Trustee. The Indenture provides that if an Event of Default occurs (which has not been cured or waived), the Trustee will be required, in the exercise of its rights and powers vested in it by the Indenture, to use the degree of care in their exercise of a prudent man in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any Holder unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

Table of Contents

Book-Entry, Delivery and Form

        The new notes initially will be represented by one or more permanent global notes in registered form without interest coupons (collectively, the "Global Notes").

        The Global Notes will be deposited upon issuance with the Trustee as custodian for DTC, in New York, New York, and registered in the name of DTC's nominee, Cede & Co., in each case for credit to an account of a direct or indirect participant in DTC as described below. Beneficial interests in the Global Notes may be held only through the Euroclear System ("Euroclear") and Clearstream Banking, S.A. ("Clearstream") (as indirect participants in DTC).

        Except as set forth below, the Global Notes may be transferred, in whole but not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in registered, certificated form ("Certificated Notes") except in the limited circumstances described below. See "—Exchange of Global Notes for Certificated Notes." Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of notes in certificated form.

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

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

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

        Investors in the Global Notes who are Participants in DTC's system 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 in such system. Euroclear and Clearstream may hold interests in the Global Notes on

70


Table of Contents

behalf of their participants through customers' securities accounts in their respective names on the books of their depositories, which are Euroclear Bank S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

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

        Except as described below, owners of beneficial interests in the Global Notes will not have notes registered in their names, will not receive physical delivery of Certificated Notes and will not be considered the registered owners or "Holders" thereof under the 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 will be payable to DTC in its capacity as the registered holder of the notes under the Indenture. Under the terms of the Indenture, the Company, the Guarantors 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 the Company, the Guarantors, the Trustee nor any agent of the Company, the Guarantors or the Trustee has or will have any responsibility or liability for:

        DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the notes, is to credit the accounts of the relevant Participants with the payment on the payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the notes as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the Trustee, the Company or the Guarantors. None of the Company, the Guarantors nor the Trustee will be liable for any delay by DTC or any of its Participants or Indirect Participants in identifying the beneficial owners of the notes, and the Company, the Guarantors 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 Participants in DTC 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 its depository; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the

71


Table of Contents

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 depository to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

        DTC has advised us that it will take any action permitted to be taken by a Holder 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 Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. None of the Company, the Guarantors nor the Trustee nor 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.

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

        Beneficial interests in a Global Note may also be exchanged for Certificated Notes in the other limited circumstances permitted by the Indenture, including if an Affiliate of ours acquires such interests. 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.

        The Indenture requires that payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) be made by wire transfer of immediately available funds to the accounts specified by the Global Note holder. With respect to Certificated Notes, the Company will make all payments of principal, premium, if any, and interest by wire transfer of

The notes represented by the Global Notes are expected to trade in DTC's Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. The Company expects that secondary trading in any Certificated Notes will also be settled in immediately available funds.

        Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant in DTC 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 or Clearstream) immediately following the settlement date of DTC. DTC has advised the Company 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 in DTC 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.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

General

        The following general discussion summarizes certain material U.S. federal income tax consequences of the exchange of old notes for new notes pursuant to this exchange offer and of the ownership and sale or other disposition of notes by the original beneficial owners of the old notes (referred to herein as "holders") who exchange old notes for new notes in this exchange offer and who hold the notes as capital assets (generally, property held for investment).

        This discussion is based upon the Internal Revenue Code of 1986 (the "Code"), regulations of the Treasury Department ("Treasury Regulations"), Internal Revenue Service (the "IRS") rulings and pronouncements, and judicial decisions now in effect. These authorities are subject to change or differing interpretations (possibly on a retroactive basis), so as to result in U.S. federal income tax consequences different from those set forth below. We have not and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of the exchange offer or of the ownership and sale or other disposition of notes which are different from those discussed below or that a contrary position taken by the IRS would not be sustained by a court.

        This discussion is a summary for general information only and does not consider all aspects of U.S. federal income taxation that may be relevant to the ownership and sale or other disposition of notes by a particular holder in light of such holder's specific circumstances. It does not describe any tax consequences arising out of the tax laws of any state, local or non-U.S. jurisdiction, any estate or gift tax consequences, or the U.S. federal income tax consequences to investors subject to special treatment under the U.S. federal income tax laws, such as:

        If a partnership, including any entity or arrangement that is treated as a partnership for U.S. federal income tax purposes, holds notes, the U.S. federal income tax treatment of a partner in the

103


Table of Contents

partnership will generally depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. If you are a partnership for U.S. federal income tax purposes (or if you are a partner in such a partnership), you should consult with your tax advisor regarding the tax consequences of the exchange of old notes for new notes pursuant to this exchange offer and of owning and selling or otherwise disposing of notes.

        You are urged to consult your own tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax considerations arising under other U.S. federal tax laws, the laws of any state, local or non-U.S. taxing jurisdiction or any applicable income tax treaty.

Certain Additional Payments

        Certain debt instruments that provide for one or more contingent payments are subject to Treasury Regulations governing contingent payment debt instruments. A payment is not treated as a contingent payment under these regulations if, as of the issue date of the debt instrument, the contingencies that could give rise to an additional payment on the debt instrument in excess of stated interest or principal are remote or incidental (considered individually and in the aggregate). In certain circumstances (see the discussion of "Description of the Notes") we may pay amounts on the notes that are in excess of the stated interest or principal of the notes. We intend to take the position that the possibility that any such payment will be made is remote. Accordingly, we will not treat the notes as contingent payment debt instruments. Our determination that these contingencies are remote is binding on you unless you disclose your contrary position to the IRS in the manner that is required by applicable Treasury Regulations. Our determination is not, however, binding on the IRS. It is possible that the IRS might take a different position from that described above, in which case the timing, character and amount of taxable income in respect of the notes may be different from that described herein. In any event, if we actually make any such payment, the timing, amount and character of a holder's income, gain or loss with respect to the notes may be affected. The remainder of this discussion assumes that the notes will not be contingent payment debt instruments. Holders are urged to consult their own tax advisors regarding the potential application to the notes of the rules regarding contingent payment debt instruments and the consequences thereof.

U.S. Holders

        A "U.S. holder" is a beneficial owner of notes that, for U.S. federal income tax purposes, is:

Exchange of an Old Note for a New Note Pursuant to the Exchange Offer

        Because the new notes will not differ materially in kind or extent from the old notes, the exchange will not constitute a taxable event for U.S. federal income tax purposes. Rather, the new notes will be treated as a continuation of the old notes. Consequently, (i) you will recognize no gain or loss upon receipt of a new note, (ii) your holding period for the new note will include your holding period for the

104


Table of Contents

old note exchanged therefor, and (iii) your basis in the new note will be the same as your basis in the old note exchanged therefor immediately before the exchange.

Taxation of Interest

        Interest on the new notes is generally taxable to you as ordinary income:

Sale or Other Disposition of Notes

        You generally must recognize taxable gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note (but not including the exchange of an old note for a new note in connection with this exchange offer). The amount of your gain or loss equals the difference between (i) the sum of the amount of cash plus the fair market value of all other property you receive for the note (to the extent such amount does not represent payment of accrued but unpaid interest, which will be taxable as ordinary income in the manner described above), and (ii) your tax basis in the note. Your initial tax basis in a note generally is the price you paid for the note. Any such gain or loss on a taxable disposition of a note will generally constitute capital gain or loss and will be long-term capital gain or loss if you hold such note for more than one year. Long-term capital gains of individuals and other non-corporate U.S. holders are generally eligible for preferential rates of taxation. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

        Information reporting may apply to payments of interest on, or the proceeds of the sale or other disposition (including a retirement or redemption) of, notes held by you, and backup withholding generally will apply to such amounts unless you provide us or the appropriate intermediary with a taxpayer identification number, certified under penalties of perjury, and comply with certain certification procedures, or you otherwise establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained if the amounts withheld exceed your actual U.S. federal income tax liability and you provide the required information or appropriate claim form to the IRS on a timely basis.

Medicare Tax

        A 3.8% tax is imposed on the "net investment income" of certain United States citizens and resident aliens, and on the undistributed "net investment income" of certain estates and trusts. Among other items, "net investment income" would generally include interest income and net gain from the sale, taxable exchange, redemption, retirement or other taxable disposition of a note, less certain deductions.

Non-U.S. Holders

        This discussion applies to you if you are a "non-U.S. holder." You are a "non-U.S. holder" for purposes of this discussion if you are a beneficial owner of notes and are for U.S. federal income tax purposes an individual, corporation, estate or trust that is not a U.S. holder.

        Special rules may apply to certain non-U.S. holders, such as "controlled foreign corporations", "passive foreign investment companies", "foreign personal holding companies" and corporations that

105


Table of Contents

accumulate earnings to avoid U.S. federal income tax, that are subject to special treatment under the Code. Such entities should consult their own tax advisors to determine the United States federal, state, local and other tax consequences that may be relevant to them.

Exchange of an Old Note for a New Note Pursuant to the Exchange Offer

        The tax consequences of the exchange offer to Non-U.S. holders are the same as described above under the heading "—U.S. Holders—Exchange of an Old Note for a New Note Pursuant to the Exchange Offer."

Income and Withholding Tax on Payments on the New Notes

        Subject to the discussion of backup withholding below, you will generally not be subject to U.S. federal income or withholding tax on payments of interest on a note, provided that:

        The applicable Treasury Regulations provide alternative methods for satisfying the certification requirement described above. In addition, special rules may apply to holders who hold notes through "qualified intermediaries" within the meaning of U.S. federal income tax laws.

        If interest on a note is effectively connected with your conduct of a trade or business in the United States and, if you are entitled to benefits under an applicable income tax treaty, such interest is attributable to a permanent establishment or a fixed base maintained by you in the United States, then such income generally will be subject to U.S. federal income tax on a net basis at the rates applicable to U.S. holders generally (and, if you are a corporate non-U.S. holder, such income may also be subject to a 30% branch profits tax or such lower rate as may be available under an applicable income tax treaty). If interest is subject to U.S. federal income tax on a net basis in accordance with the rules described in the preceding sentence, payments of such interest will not be subject to withholding of U.S. federal income tax so long as you provide the applicable withholding agent with a properly completed Form W-8ECI (or other applicable form), signed under penalties of perjury.

106


Table of Contents

        A non-U.S. holder that does not qualify for exemption from withholding under the preceding paragraphs generally will be subject to withholding of U.S. federal income tax at the rate of 30% on payments of interest on the notes, unless such non-U.S. holder provides the applicable withholding agent with a properly executed IRS Form W-8BEN (or other applicable form) claiming an exemption from or reduction in withholding under the benefits of an applicable income tax treaty.

        NON-U.S. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS ABOUT ANY APPLICABLE INCOME TAX TREATIES, WHICH MAY PROVIDE FOR AN EXEMPTION FROM OR A LOWER RATE OF WITHHOLDING TAX, EXEMPTION FROM OR REDUCTION OF BRANCH PROFITS TAX, OR OTHER RULES DIFFERENT FROM THOSE DESCRIBED ABOVE.

Sale or Other Disposition of Notes

        Subject to the discussion of backup withholding below, any gain realized by you on the sale, exchange, redemption, retirement or other disposition of a note generally will not be subject to U.S. federal income or withholding tax, unless:

        If the first bullet point applies, you generally will be subject to U.S. federal income tax with respect to such gain in the same manner as U.S. holders, as described above. In addition, if you are a corporation, you may also be subject to the branch profits tax described above. If the third bullet point applies, you generally will be subject to U.S. federal income tax at a rate of 30% (or at a reduced rate under an applicable income tax treaty) on the amount by which your capital gains from U.S. sources, including gain from such disposition, exceed your capital losses allocable to U.S. sources recognized in the same taxable year as the disposition, even though you are not considered a resident of the United States under the Code.

Information Reporting and Backup Withholding

        Payments to you of interest on a note, and amounts withheld from such payments, if any, generally will be required to be reported to the IRS and to you and information returns reporting such payments and any withholding may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable income tax treaty or agreement. These reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable income tax treaty. Backup withholding generally will not apply to payments of interest and principal on a note if you duly provide a certification as to your non-U.S. status, or you otherwise establish an exemption, provided that we or our paying agent do not have actual knowledge or reason to know that you are a United States person.

        Payment of the proceeds on the sale or other disposition of a note by you within the United States or conducted through certain U.S.-related intermediaries generally will not be subject to information reporting requirements and backup withholding provided you properly certify under penalties of perjury as to your non-U.S. status and certain other conditions are met, or you otherwise establish an exemption.

107


Table of Contents

        Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained if the amounts withheld exceed your actual U.S. federal income tax liability and you provide the required information or appropriate claim form to the IRS on a timely basis.

Foreign Account Tax Compliance Act

        Pursuant to the Foreign Account Tax Compliance Act (commonly known as "FATCA"), if there is a "material modification" of the notes on or after July 1, 2014, we may thereafter be required to withhold U.S. tax at the rate of 30% on payments of interest made after that date or on the gross proceeds from the sale or other taxable disposition of the notes on or after January 1, 2017, made to non-U.S. financial institutions and certain other holders (including, in some instances, where such an entity is acting as an intermediary) that fail to comply with certain information reporting obligations. Holders should consult their own tax advisors regarding this legislation and whether it may be relevant to their acquisition, ownership and disposition of notes.

        THE PRECEDING DISCUSSION OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES OF PURCHASING, HOLDING, AND DISPOSING OF OUR NOTES, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

PLAN OF DISTRIBUTION

        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 "Exchange Offer—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 date of this prospectus (or such shorter period during which exchanging broker-dealer or initial purchaser is required by law to deliver a prospectus). Furthermore, we agreed to

109


Table of Contents

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 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.

        We refer you to the Prospectus, dated April 22, 2014 (the "Prospectus"), of Laredo Petroleum, Inc. (the "Issuer"), and this Letter of Transmittal (the "Letter of Transmittal"), which together describe the Issuer's offer (the "Exchange Offer") to exchange its 55/8% Senior Notes due 2022 (the "new notes") that have been registered under the Securities Act of 1933, as amended (the "Securities Act"), for a like principal amount of its issued and outstanding 55/8% Senior Notes due 2022 (the "old notes"). 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 to which the Exchange Offer is extended. The Issuer shall notify the Exchange Agent in writing of any extension and each registered holder of the old notes of any extension via a press release or other public announcement prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

        This Letter of Transmittal is to be used by holders of the old notes. Tender of old notes is to be made according to the Automated Tender Offer Program ("ATOP") of The Depository Trust Company ("DTC") pursuant to the procedures set forth in the Prospectus under the caption "Exchange Offer—Procedures for Tendering." DTC participants that are accepting the Exchange Offer must transmit their acceptance to DTC, which will verify the acceptance and execute a book-entry delivery to the Exchange Agent's DTC account. DTC will then send a computer generated message known as an "agent's

        5.     By tendering old notes in the Exchange Offer, you hereby represent and warrant that:

        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 January 23, 2014 (the "Registration Rights Agreement"), by and among the Issuer, the guarantor named therein, and the Initial Purchasers (as defined therein).

each of the directors of the Issuer, each of the officers of the Issuer who signs such shelf registration statement, each person who controls the Issuer within the meaning of either the Securities Act or the Securities Exchange Act of 1934, as amended, and each other holder of old notes, from and against any and all losses, claims, damages or liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in any shelf registration statement or prospectus, or in any supplement thereto or amendment thereof, or caused by the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; but only with respect to information relating to you furnished in writing by or on behalf of you expressly for use in a shelf registration statement, a prospectus or any amendments or supplements thereto. Any such indemnification shall be governed by the terms and subject to the conditions set forth in the Registration Rights Agreement, including, without limitation, the provisions regarding notice, retention of counsel, contribution and payment of expenses set forth therein. The above summary of the indemnification provision of the Registration Rights Agreement is not intended to be exhaustive and is qualified in its entirety by the Registration Rights Agreement.

        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.
