PROSPECTUS

$250,000,000

Clean Harbors, Inc.

7⁵/8% Senior Secured Notes due 2016

On March 24, 2011, we issued $250.0 million aggregate principal amount of 7⁵/8% senior secured notes due 2016 (the "old notes") in an unregistered private placement under an indenture dated August 14, 2009, pursuant to which we had previously issued on August 14, 2009, $300.0 million aggregate principal amount of 7⁵/8% notes due 2016 (the "original 2016 notes"). On September 28, 2010, we redeemed $30.0 million of the original 2016 notes, and there are therefore now outstanding under the indenture $270.0 million of original 2016 notes and $250.0 million of old notes.

We are offering to exchange up to $250.0 million aggregate principal amount of 7⁵/8% senior secured notes due 2016 (the "new notes") that we have registered under the Securities Act of 1933 for up to all of the $250.0 million aggregate principal amount of outstanding old notes. This prospectus refers to the new notes, the old notes and the original 2016 notes collectively as the "notes." The old notes and the original 2016 notes are, and the new notes will be, fully and unconditionally and jointly and severally guaranteed by substantially all of our existing and future domestic restricted subsidiaries, and such guarantees are securities which are being offered along with the new notes by this prospectus.

The Exchange Offer

•: We will exchange an equal principal amount of new notes for all old notes that are validly tendered and not validly withdrawn.
•: You may withdraw tenders of outstanding old notes at any time prior to the expiration of the exchange offer.
•: The exchange offer is subject to the satisfaction of limited, customary conditions.
•: The exchange offer will expire at 5:00 p.m., New York City time, on , 2011, unless extended.
•: The exchange of old notes for new notes in the exchange offer will not be a taxable event for U.S. federal income tax purposes.
•: We will not receive any proceeds from the exchange offer.

The New Notes

•: The terms of the new notes are substantially identical to the terms of the old notes for which they may be exchanged pursuant to the exchange offer, except that the new notes are registered under the Securities Act and do not contain transfer restrictions, registration rights or provisions for additional interest under certain circumstances.

See "Risk Factors" beginning on page 11 to read about factors you should consider in connection with the exchange offer.

Each broker-dealer that receives new notes for its own account in exchange for old notes acquired by such broker-dealer as a result of market-making activities or other trading activities must deliver a prospectus in connection with a resale of the new notes and provide us in the letter of transmittal with a signed acknowledgement of this obligation. The letter of transmittal states that by so acknowledging and by delivering a prospectus, any such broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. A broker-dealer may use this prospectus, as amended or supplemented from time to time, in connection with any such resale of new notes. We have agreed that for a period of 180 days after the expiration date of the exchange offer, we will make this prospectus available to broker-dealers for use in connection with any such resale of new notes. See "Plan of Distribution."

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

The date of this prospectus is , 2011.

We obtained the market and related information used in this prospectus from our own research, surveys or studies conducted by third parties and industry or general publications, such as EI Digest, and other publicly available sources. Industry and general publications and surveys generally state that they have obtained information from sources believed to be reliable.

Forward-Looking Statements

This prospectus includes "forward-looking statements," as defined by federal securities laws, with respect to our financial condition, results of operations and business and our expectations or beliefs concerning future events. Words such as, but not limited to, "believe," "expect," "anticipate," "estimate," "intend," "plan," "targets," "likely," "will," "would," "could" and similar expressions or phrases identify forward-looking statements. Such statements may include, but are not limited to, statements about future financial and operating results, the Company's plans, objectives, expectations and intentions and other statements that are not historical facts.

All forward-looking statements involve risks and uncertainties. Many risks and uncertainties are inherent in the environmental, industrial and energy services industries. Others are more specific to our operations. The occurrence of the events described, and the achievement of the expected results, depend on many events, some or all of which are not predictable or within our control. Actual results may differ materially from expected results.

Factors that may cause actual results to differ from expected results include, among others:

•: our ability to manage the significant environmental liabilities that we assumed in connection with prior acquisitions and may assume in connection with future acquisitions;
•: the availability and costs of liability insurance and financial assurance required by governmental entities related to our facilities;
•: general conditions in the oil and gas industries, particularly in the Alberta oil sands and other parts of Western Canada;
•: our ability to integrate into our operations the respective operations of Peak Energy Services Ltd. ("Peak") which we acquired on June 10, 2011, and any additional acquisitions we may complete in the future;
•: the possibility that the expected synergies from the Peak acquisition and any additional acquisitions we may complete in the future will not be fully realized;
•: exposure to unknown liabilities in connection with the Peak acquisition and any additional acquisitions we may complete in the future;
•: the extent to which our major customers commit to and schedule major projects;
•: the unpredictability of emergency response events that may require cleanup and other services by us for uncertain durations of time;
•: our future cash flow and earnings;
•: our ability to meet our debt obligations;
•: our ability to increase our market share;

iii

Table of Contents

•: the effects of general economic conditions in the United States, Canada and other territories and countries where we conduct business;
•: the effect of economic forces and competition in specific marketplaces where we compete;
•: the possible impact of new regulations or laws pertaining to all activities of our operations;
•: the outcome of litigation or threatened litigation or regulatory actions;
•: the effect of commodity pricing on our overall revenues and profitability;
•: possible fluctuations in quarterly or annual results or adverse impacts on our results caused by the adoption of new accounting standards or interpretations or regulatory rules and regulations;
•: the effect of weather conditions or other aspects of the forces of nature on field or facility operations;
•: the effects of industry trends in the environmental, energy and industrial services marketplaces; and
•: the effects of conditions in the financial services industry on the availability of capital and financing.

All future written and verbal forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to above. We undertake no obligation, and specifically decline any obligation, to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this prospectus might not occur.

See "Risk Factors" in this prospectus for a more complete discussion of these risks and uncertainties and for other risks and uncertainties. These factors and the other risk factors described in this prospectus are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements and other unknown or unpredictable factors also could harm our results. Consequently, actual results or developments anticipated by us may not be realized and, even if substantially realized, they may not have the expected consequences to, or effects on, us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

SUMMARY

This summary highlights information contained elsewhere in this prospectus, is not complete and does not contain all of the information that may be important to you. We urge you to read this entire prospectus carefully, including the "Risk Factors" section and the consolidated financial statements and related notes included herein.

Our Company

We are a leading provider of environmental, energy and industrial services throughout North America. We serve over 50,000 customers, including a majority of Fortune 500 companies, thousands of smaller private entities and numerous federal, state, provincial and local governmental agencies. We have more than 175 locations, including over 50 waste management facilities, throughout North America in 38 U.S. states, seven Canadian provinces, Mexico and Puerto Rico. We also operate international locations in Bulgaria, China, Singapore, Sweden, Thailand and the United Kingdom.

The wastes that we handle include materials that are classified as "hazardous" because of their unique properties, as well as other materials subject to federal and state environmental regulation. We provide final treatment and disposal services designed to manage hazardous and non-hazardous wastes which cannot be economically recycled or reused. We transport, treat and dispose of industrial wastes for commercial and industrial customers, health care providers, educational and research organizations, other environmental services companies and governmental entities.

As a result of our acquisition of Eveready Inc., or "Eveready," on July 31, 2009, we have also become a major provider of industrial maintenance and production, lodging, and exploration services to the oil and gas, pulp and paper, manufacturing and power generation industries throughout North America.

Our Services

We report our business in four operating segments, consisting of:

•: Technical Services—provides a broad range of hazardous material management services including the packaging, collection, transportation, treatment and disposal of hazardous and non-hazardous waste at Company owned incineration, landfill, wastewater, and other treatment facilities.
•: Field Services—provides a wide variety of environmental cleanup services on customer sites or other locations on a scheduled or emergency response basis including tank cleaning, decontamination, remediation, and spill cleanup.
•: Industrial Services—provides industrial and specialty services, such as high-pressure and chemical cleaning, catalyst handling, decoking, materials handling and industrial lodging services to refineries, oil sands facilities, pulp and paper mills, and other industrial facilities.
•: Oil and Gas Field Services—provides fluid handling, fluid hauling, down hole servicing, exploration, mapping and directional boring services to the energy sector serving oil and gas exploration, production, and power generation.

Technical Services and Field Services are included as part of Clean Harbors Environmental Services, and Industrial Services and Oil and Gas Field Services are included as part of Clean Harbors Energy and Industrial Services.

The Environmental Services Industry

According to industry reports, the hazardous waste disposal market in North America generates total revenues in excess of $2.0 billion per year. We also service the much larger industrial maintenance market. The $2.0 billion estimate does not include the industrial maintenance market, except to the extent that the costs of disposal of hazardous wastes generated as a result of industrial maintenance are included. The largest generators of hazardous waste materials are companies in the chemical, petrochemical, primary metals, paper, furniture, aerospace and pharmaceutical industries.

The hazardous waste management industry was "created" in 1976 with the passage of the Resource Conservation and Recovery Act, or "RCRA." RCRA requires waste generators to distinguish between "hazardous" and "non-hazardous" wastes, and to treat, store and dispose of hazardous waste in accordance with specific regulations. This new regulatory environment, combined with strong economic growth, increased corporate concern about environmental liabilities, and the early stage nature of the hazardous waste management industry contributed initially to rapid growth in the industry. However, by the mid to late 1990s, the hazardous waste management industry was characterized by overcapacity, minimal regulatory advances and pricing pressure. Since 2001, over one-third of all North American commercial incineration capacity has been eliminated, and we believe that competition has been reduced through consolidation and that new regulations have increased the overall barriers to entry.

The collection and disposal of solid and hazardous wastes are subject to local, state, provincial and federal requirements and regulations, which regulate health, safety, the environment, zoning and land use. Among these regulations in the United States is the Comprehensive Environmental Response, Compensation and Liability Act of 1980, or "CERCLA," which holds generators and transporters of hazardous substances, as well as past and present owners and operators of sites where there has been a hazardous release, strictly, jointly and severally liable for environmental cleanup costs resulting from the release or threatened release of hazardous substances. Canadian companies are regulated under similar regulations, but the responsibility and liability associated with the waste passes from the generator to the transporter or receiver of the waste, in contrast to provisions of CERCLA.

Recent Developments

Acquisition of Peak

On June 10, 2011, we acquired Peak Energy Services Ltd., or "Peak," a corporation headquartered in Calgary, Alberta, in an all-cash transaction. Peak is a diversified energy services organization operating in western Canada and the U.S. Through its various operating divisions, Peak provides drilling and production services to its customers both in the conventional and unconventional oil and natural gas industry as well as the oil sands regions of western Canada. Peak also provides water technology solutions to a variety of customers throughout North America. Peak has approximately 900 employees. Prior to the acquisition, Peak's common shares traded on the Toronto Stock Exchange under the symbol "PES."

Under the terms of the acquisition agreement, we acquired 100% of Peak's outstanding common shares (other than the 3.15% of Peak's outstanding common shares which we had previously acquired) in exchange for approximately Cdn $160.3 million in cash (Cdn $0.95 for each Peak share), including cash payments to holders of in-the-money stock options, and we assumed and paid off Peak's net debt of approximately Cdn $36.3 million. The total acquisition price, which includes the previous investment in Peak shares referred to above, was approximately Cdn $201.8 million or U.S. $206.8 million based on an exchange rate of 0.976057 Cdn $ to one U.S. $ on June 10, 2011.

Amendment and Restatement of Revolving Credit Facility

On May 31, 2011, we entered into an amendment and restatement of our previously existing revolving credit facility with Bank of America, N.A. ("BofA"), as agent for the lenders under the facility. The principal changes to the terms of the facility were to:

(i) increase the maximum amount of revolving loans and letters of credit which Clean Harbors, Inc. (the "Company") may obtain under the facility from $120.0 million to $150.0 million (with a $140.0 million sub-limit for letters of credit);

(ii) add one of the Company's Canadian subsidiaries (the "Canadian Borrower") as a party to the facility and allow the Canadian Borrower to obtain up to $100.0 million of revolving loans and letters of credit (with a $75.0 million sub-limit for letters of credit), with the obligations of the Canadian Borrower under the facility secured by a first lien on the accounts receivable of the Canadian Borrower and the Company's other Canadian subsidiaries, and the Company and its U.S. subsidiaries guaranteeing the obligations of the Canadian Borrower but the Canadian Borrower and the Company's other Canadian subsidiaries having no guarantee or other responsibility for the obligations of the Company or its U.S. subsidiaries under the facility;

(iii) reduce the interest rate on borrowings under the facility, in the case of LIBOR loans, from LIBOR plus an applicable margin ranging (based primarily on the level of our consolidated fixed charge coverage ratio for the most recently completed four fiscal quarter measurement period) from 2.25% to 2.75% per annum to LIBOR plus an applicable margin ranging from 1.75% to 2.25% per annum and, in the case of base rate loans, from BofA's base rate plus an applicable margin ranging from 1.25% to 1.75% per annum to BofA's base rate plus an applicable margin ranging from 0.75% to 1.25% per annum; and

(iv) extend the term of the facility so that it will expire on the first to occur of (A) May 31, 2016 or (B) 60 days prior to the maturity of our outstanding senior secured notes on August 15, 2016 if the notes have not by then been refinanced, defeased or reserved against the borrowing base on terms reasonably acceptable to the agent under the amended and restated credit agreement.

Status of Proposed Acquisition of Badger

On January 25, 2011, we entered into a definitive agreement to acquire Badger Daylighting Ltd. ("Badger"), an Alberta corporation headquartered in Calgary, Alberta. Under the terms of the acquisition agreement, a condition to the respective obligations of each of us and Badger to complete the transaction was approval of the transaction by a required affirmative vote of at least 66²/3% of Badger's shareholders and option holders voting on the matter. At a meeting held on April 26, 2011, the Badger shareholders and option holders failed to approve the transaction by the required vote. In accordance with the terms of the acquisition agreement, we terminated the agreement on April 26, 2011. The acquisition agreement provided that if we terminated the agreement because of a failure by the Badger shareholders and option holders to approve the transaction by the required vote, Badger was obligated to reimburse our out of pocket expenses incurred in connection with the proposed transaction including the financing thereof, up to a maximum of Cdn $1.5 million. Based on a demand letter which we sent to Badger in May 2011, we received U.S. $1.1 million from Badger in June for reimbursement in accordance with this provision of the agreement.

Proposed Additional Acquisitions

In May and June 2011, we signed an acquisition agreement to acquire one privately owned U.S. company which treats refinery waste streams primarily in the U.S. and an acquisition agreement to acquire substantially all of the assets of a division of a Canadian public company which provides

geospatial, line clearing and drilling services in Canada and the U.S. The agreements provide for a total combined purchase price of approximately $100.0 million, or approximately 5.3% of our total assets at March 31, 2011. Each proposed acquisition is subject to customary closing conditions and no assurance can be given that either or both of the proposed acquisitions will be consummated.

Stock Split of Common Stock

On June 8, 2011, our board of directors authorized a two-for-one split of our common stock in the form of a stock dividend of one share for each outstanding share. The stock dividend will be payable on July 26, 2011 to holders of record at the close of business on July 6, 2011. As of June 30, 2011, we had outstanding a total of 26,493,061 common shares, which will be increased to 52,986,122 outstanding common shares as a result of the stock split.

The Exchange Offer


Background		On March 24, 2011, we completed a private placement of the old notes. In connection with that private placement, we entered into a registration rights agreement with Goldman Sachs & Co. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, the initial purchasers of the old notes, in which we agreed to deliver this prospectus to you and to make the exchange offer.
The Exchange Offer		We are offering to exchange up to $250.0 million aggregate principal amount of our new notes which have been registered under the Securities Act for up to all of the $250.0 million aggregate principal amount of our old notes. You may tender old notes only in integral multiples of $1,000 principal amount.
Resale of New Notes		Based on interpretive letters of the SEC staff to third parties, we believe that you may resell and transfer the new notes issued pursuant to the exchange offer in exchange for old notes without compliance with the registration and prospectus delivery provisions of the Securities Act, if:
		• you are acquiring the new notes in the ordinary course of your business for investment purposes;
		• you have no arrangement or understanding with any person to participate in the distribution of the new notes; and
		• you are not our affiliate as defined under Rule 405 under the Securities Act.
		If you fail to satisfy any of these conditions, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes.
		Broker-dealers that acquired old notes directly from us, but not as a result of market-making activities or other trading activities, must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes.
		Each broker-dealer that receives new notes for its own account pursuant to the exchange offer in exchange for old notes that it acquired as a result of market-making or other trading activities must deliver a prospectus in connection with any resale of the new notes and provide us with a signed acknowledgement of this obligation.
Transfer Restrictions		The new notes have been registered under the Securities Act and generally will be freely transferable. We do not intend to list the notes on any securities exchange.

Accordingly, a liquid market for the new notes may not develop or be maintained.
Consequences If You Do Not Exchange Your Old Notes		Old notes that are not tendered in the exchange offer or are not accepted for exchange will continue to bear legends restricting their transfer. You will not be able to offer or sell the old notes unless:
		• an exemption from the requirements of the Securities Act is available to you;
		• we register the resale of old notes under the Securities Act; or
		• the transaction requires neither an exemption from nor registration under the requirements of the Securities Act.

Summary Description of the New Notes

The form and terms of the new notes are substantially identical to the form and terms of the old notes, except that:

•: we have registered the new notes under the Securities Act and the new notes will therefore not bear legends restricting their transfer;
•: the new notes will have a different CUSIP number than the old notes (with the CUSIP number for the new notes being the same as that of the $270.0 million of original 2016 notes which are also now outstanding under the indenture); and
•: specified rights under the registration rights agreement, including the provisions providing for registration rights and the payment of additional interest on the old notes in specified circumstances, will be limited or eliminated.

The new notes will evidence the same debt as the old notes and will rank equally with the old notes. The same indenture will govern both the old notes and the new notes, as well as the $270.0 million of original 2016 notes which are also now outstanding under the indenture. This prospectus refers to the old notes, the new notes and the original 2016 notes collectively as the "notes."


Issuer		Clean Harbors, Inc. (the "Issuer").
New Notes Offered		$250,000,000 aggregate principal amount of 7⁵/8% senior secured notes due 2016.
Maturity Date		August 15, 2016.
Interest Payments		Interest on the notes is payable semi-annually in arrears on February 15 and August 15 of each year. The first payment of interest on the new notes will be on February 15, 2012.
Guarantees		The old notes are, and the new notes will be, fully and unconditionally and jointly and severally guaranteed on a senior secured basis by substantially all of our existing and future domestic subsidiaries. The old notes are not, and the new notes will not be, guaranteed by our Canadian and other foreign subsidiaries.
Collateral		The old notes and the related guarantees are, and the new notes and the related guarantees will be, secured by a first-priority lien (subject to certain exceptions and permitted liens) on all the tangible and intangible assets of the Issuer and the guarantors other than ABL Collateral (as defined below) in each case held by us and the guarantors (such assets, the "Notes Collateral"). The old notes and the related guarantees are, and the new notes and the related guarantees will be, also secured by a second-priority lien (subject to certain exceptions and permitted liens) on all accounts receivable, related general intangibles and instruments and proceeds related to the foregoing, in each case held by the Issuer and the guarantors (such assets, the "ABL Collateral"). We refer to the Notes Collateral and the ABL Collateral together as the "Collateral." See "Description of the Notes—Security."

Table of Contents


Ranking		The old notes are, and the new notes will be, our and the guarantors' secured senior obligations. Subject to the lien priorities described below, the old notes and the new notes rank equally with our and the guarantors' existing and future senior obligations and senior to any future indebtedness that is specifically subordinated to the notes and the guarantees.
		As of March 31, 2011, we and our guarantor subsidiaries had no outstanding loans under our revolving credit facility, but we then had $82.4 million of outstanding letters of credit. The notes and the guarantees rank effectively junior to debt (including loans and reimbursement obligations in respect of outstanding letters of credit) under our revolving credit agreement to the extent of the value of the ABL Collateral. Furthermore, our non-guarantor subsidiaries had as of March 31, 2011 approximately $134.6 million of total liabilities (excluding intercompany liabilities and debt). The notes and the guarantees rank structurally junior to those obligations of our non-guarantor subsidiaries.
Optional Redemption		We may redeem some or all of the notes at any time on or after August 15, 2012, at the redemption prices described in "Description of the Notes—Redemption—Optional Redemption," plus accrued and unpaid interest to the date of redemption. At any one time on or after September 29, 2011 but prior to August 15, 2012, we may also redeem up to $30.0 million (10% of the aggregate principal amount of the notes originally issued under the indenture) at a price equal to 103% of the principal amount thereof plus any accrued and unpaid interest thereon. At any time prior to August 15, 2012, we may also redeem some or all of the notes at a price equal to 100% of the principal amount thereof plus the make-whole premium described under "Description of the Notes—Redemption—Optional Redemption."
		At any time prior to August 15, 2012, we may also redeem up to $105.0 million of the notes (35% of the aggregate principal amount originally issued under the indenture) with the net proceeds of certain equity offerings at a redemption price equal to 107.625% of the principal amount of the notes plus accrued and unpaid interest to the date of redemption. We may make that redemption only if, after the redemption, at least 65% of the aggregate principal amount of the notes originally issued under the indenture remains outstanding.
Change of Control; Asset Sales		If we experience a Change of Control (as defined under "Description of the Notes—Change of Control"), we will be required to make an offer to repurchase the notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of repurchase.

Table of Contents


		If we sell assets under certain circumstances, we will be required to make an offer to purchase the notes at their face amount, plus accrued and unpaid interest to the purchase date. See "Description of the Notes—Certain Covenants—Limitation on Asset Sales."
Certain Covenants		The indenture governing the notes restricts our ability and the ability of our restricted subsidiaries to, among other things:
		• incur or guarantee additional indebtedness (including, for this purpose, reimbursement obligations under letters of credit) or issue preferred stock;
		• pay dividends or make other distributions to our stockholders;
		• purchase or redeem capital stock or subordinated indebtedness;
		• make investments;
		• create liens;
		• incur restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us;
		• sell assets, including capital stock of our subsidiaries;
		• consolidate or merge with or into other companies or transfer all or substantially all of our assets; and
		• engage in transactions with affiliates.
		These covenants are subject to a number of important qualifications and exceptions. See "Description of the Notes—Certain Covenants."
Tax Considerations		As discussed in more detail below in the section "United States Federal Income and Estate Tax Considerations," we intend, for U.S. federal income tax purposes, to treat the issuance of the old notes on March 24, 2011 as a "qualified reopening" of the issuance of the original 2016 notes on August 14, 2009. Accordingly, we intend to treat, for U.S. federal income tax purposes, the old notes, and the new notes issued in exchange for old notes pursuant to this exchange offer, as having the same issue date, issue price and adjusted issue price as the original 2016 notes, and therefore as having been issued with the same amount of original issue discount ("O.I.D.") as the original 2016 notes. Nevertheless, a holder that purchased old notes on March 24, 2011 at the initial offering price of 104.5% of their stated principal amount (plus accrued interest), and which exchanges such old notes for new notes pursuant to this exchange offer, should be deemed to have purchased its notes at a "premium" and should therefore not be required to include any O.I.D. in gross income.

RISK FACTORS

Before you tender your old notes, you should be aware that there are various risks involved in an investment in the notes, including those we describe below. You should consider carefully these risk factors together with all of the information included or referred to in this prospectus before you decide to tender your old notes in this exchange offer.

Risks Related to the Exchange Offer and the Notes

If you fail to exchange your old notes in accordance with the terms described in this prospectus, you may not be able to sell your old notes.

Old notes which you do not tender or we do not accept will, following the exchange offer, continue to be restricted securities. You may not offer or sell untendered old notes except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We will issue new notes in exchange for your old notes pursuant to the exchange offer only if you satisfy the procedures and conditions described in this prospectus. These procedures and conditions include timely receipt by the exchange agent of your old notes and a properly completed and duly executed letter of transmittal.

Because we anticipate that most holders of old notes will elect to exchange their old notes, the market for any old notes remaining after the completion of the exchange offer will likely be adversely affected. Any old notes tendered and exchanged in the exchange offer will reduce the aggregate principal amount of the old notes outstanding. Following the exchange offer, if you did not tender your old notes, you generally will not have any further registration rights and your old notes will continue to be subject to transfer restrictions. Accordingly, you may not be able to sell your old notes.

Even if you accept the exchange offer, you may not be able to sell your new notes in the future at favorable prices.

There has been no public market for the old notes. Despite our registration of the new notes that we are offering in the exchange offer:

•: the initial purchasers of the old notes are not obligated to make a market in the new notes and any such market-making may be discontinued at any time at the sole discretion of the initial purchasers; and
•: no significant market for the new notes may develop.

The liquidity of, and trading market for, the new notes may also be adversely affected by, among other things:

•: prevailing interest rates;
•: our operating performance and financial condition;
•: the interest of securities dealers in making a market; and
•: the market for similar securities.

A real or perceived economic downturn or higher interest rates could therefore cause a decline in the market price of the notes and thereby negatively impact the market for the notes. Because the notes may be thinly traded, it may be more difficult to sell and accurately value the notes. In addition, as has recently been evident in the current turmoil in the global financial markets, the present economic slowdown and the uncertainty over its breadth, depth and duration, the entire high-yield bond market can experience sudden and sharp price swings, which can be exacerbated by large or sustained sales by major investors in the notes, a high-profile default by another issuer, or a change in

Table of Contents

the market's psychology regarding high-yield notes. Moreover, if one of the major rating agencies were to lower its credit rating of the notes, the market price of the notes would likely decline.

Our substantial levels of outstanding debt and letters of credit could adversely affect our financial condition and ability to fulfill our obligations.

On March 31, 2011, we and our guarantor subsidiaries had outstanding $520.0 million aggregate principal amount of notes, $13.4 million of capital lease obligations, no revolving loans, and $82.4 million of letters of credit. Our substantial levels of outstanding debt and letters of credit may:

•: adversely impact our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions or other general corporate purposes or to repurchase the notes from holders upon any change of control;
•: require us to dedicate a substantial portion of our cash flow to the payment of interest on our debt and fees on our letters of credit, which reduces the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes;
•: subject us to the risk of increased sensitivity to interest rate increases based upon variable interest rates, including our borrowings (if any) under our revolving credit facility;
•: increase the possibility of an event of default under the financial and operating covenants contained in our debt instruments; and
•: limit our ability to adjust to rapidly changing market conditions, reduce our ability to withstand competitive pressures and make us more vulnerable to a downturn in general economic conditions of our business than our competitors with less debt.

Our ability to make scheduled payments of principal or interest with respect to our debt, including the notes, any revolving loans and our capital leases, and to pay fee obligations with respect to our letters of credit, will depend on our ability to generate cash and on our future financial results. Our ability to generate cash depends on, among other things, the demand for our services, which is subject to market conditions in the environmental, energy and industrial services industries, the occurrence of events requiring major remedial projects, changes in government environmental regulation, general economic conditions, and financial, competitive, regulatory and other factors affecting our operations, many of which are beyond our control. Our operations may not generate sufficient cash flow, and future borrowings may not be available under our revolving credit facility or otherwise, in an amount sufficient to enable us to pay our debt and fee obligations respecting our letters of credit, or to fund our other liquidity needs. If we are unable to generate sufficient cash flow from operations in the future to service our debt and letter of credit fee obligations, we might be required to refinance all or a portion of our existing debt and letter of credit facilities or to obtain new or additional such facilities. However, we might not be able to obtain any such new or additional facilities on favorable terms or at all.

Despite our substantial levels of outstanding debt and letters of credit, we could incur substantially more debt and letter of credit obligations in the future.

Although our revolving credit agreement and the indenture governing the notes contain restrictions on the incurrence of additional indebtedness (including, for this purpose, reimbursement obligations under outstanding letters of credit), these restrictions are subject to a number of qualifications and exceptions and the additional amount of indebtedness which we might incur in the future in compliance with these restrictions could be substantial. In particular, we had available at May 31, 2011 (after giving effect to the amendment and restatement of our revolving credit facility which then became effective), up to an additional approximately $167.7 million for purposes of additional borrowings and letters of credit. The indenture governing the notes also allows us to borrow significant amounts of money from

Table of Contents

other sources. These restrictions would also not prevent us from incurring obligations (such as operating leases) that do not constitute "indebtedness" as defined in the relevant agreements. To the extent we incur in the future additional debt and letter of credit obligations, the related risks will increase.

The covenants in our debt agreements restrict our ability to operate our business and might lead to a default under our debt agreements.

Our revolving credit agreement and the indenture governing our notes limit, among other things, our ability and the ability of our restricted subsidiaries to:

•: incur or guarantee additional indebtedness (including, for this purpose, reimbursement obligations under letters of credit) or issue preferred stock;
•: pay dividends or make other distributions to our stockholders;
•: purchase or redeem capital stock or subordinated indebtedness;
•: make acquisitions and other investments;
•: create liens;
•: incur restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us;
•: sell assets, including capital stock of our subsidiaries;
•: consolidate or merge with or into other companies or transfer all or substantially all of our assets; and
•: engage in transactions with affiliates.

As a result of these covenants, we may not be able to respond to changes in business and economic conditions and to obtain additional financing, if needed, and we may be prevented from engaging in transactions that might otherwise be beneficial to us. Our revolving credit facility requires, and our future credit facilities may require, us to maintain under certain circumstances specified financial ratios and satisfy certain financial condition tests. Our ability to meet these financial ratios and tests can be affected by events beyond our control, and we may not be able to meet those tests. The breach of any of these covenants could result in a default under our revolving credit facility or future credit facilities. Upon the occurrence of an event of default, the lenders could elect to declare all amounts outstanding under such credit facilities, including accrued interest or other obligations, to be immediately due and payable. If amounts outstanding under such credit facilities were to be accelerated, our assets might not be sufficient to repay in full that indebtedness and our other indebtedness, including the notes.

Our revolving credit agreement and the indenture governing our notes also contain cross-default and cross-acceleration provisions. Under these provisions, a default or acceleration under one instrument governing our debt may constitute a default under our other debt instruments that contain cross-default or cross-acceleration provisions, which could result in the related debt and the debt issued under such other instruments becoming immediately due and payable. In such event, we would need to raise funds from alternative sources, which funds might not be available to us on favorable terms, on a timely basis or at all. Alternatively, such a default could require us to sell assets and otherwise curtail operations to pay our creditors. The proceeds of such a sale of assets, or curtailment of operations, might not enable us to pay all of our liabilities.

Table of Contents

The notes are structurally subordinated to all debt of our subsidiaries that are not guarantors of the notes and may be effectively subordinated to certain of our and the guarantors' environmental liabilities.

All of our domestic subsidiaries (other than domestic subsidiaries of our foreign subsidiaries) have guaranteed the notes, but our Canadian and other foreign subsidiaries are not guarantors. Noteholders will not have any claim as a creditor against our subsidiaries that are not guarantors of the notes. Accordingly, all obligations of our non-guarantor subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the notes. The indenture and our revolving credit facility allow us to incur substantial debt at our foreign subsidiaries all of which would be structurally senior to the notes and the guaranties to the extent of the assets of those foreign subsidiaries. On March 31, 2011, our non-guarantor subsidiaries had approximately $134.6 million of total liabilities (excluding intercompany liabilities and debt) and held approximately 42.6% of our total assets (excluding intercompany receivables), and for the three months ended March 31, 2011, our non-guarantor subsidiaries generated approximately 44.3% of our consolidated revenues. Furthermore, in the event of a bankruptcy or similar proceeding relating to us or the guarantors, our and their existing and future environmental liabilities may effectively rank senior in right of payment to the notes and the guarantees under certain federal and state bankruptcy and environmental laws.

Indebtedness under our revolving credit facility will be effectively senior to the notes to the extent of the value of the ABL Collateral.

Our revolving credit facility is collateralized by a first-priority lien on the ABL Collateral. The first-priority liens on the ABL Collateral will be higher in priority as to the ABL Collateral than the security interests in such Collateral securing the notes and the guarantees. On May 31, 2011 (after giving effect to the amendment and restatement of our revolving credit facility which then became effective), we had approximately $167.7 million of availability for purposes of future borrowings and letters of credit under our revolving credit facility, after taking into account borrowing base limitations and the $82.4 million of letters of credit which were then outstanding. The notes and the related guarantees are secured, subject to permitted liens, by a second-priority lien on the ABL Collateral. Holders of the indebtedness under our revolving credit facility will be entitled to receive proceeds from the realization of value of the ABL Collateral to repay such indebtedness in full before the holders of the notes will be entitled to any recovery from the ABL Collateral.

Accordingly, holders of the notes will only be entitled to receive proceeds from the realization of value of the ABL Collateral after all indebtedness and other obligations under our revolving credit facility are repaid in full. As a result, the notes will be effectively junior in right of payment to indebtedness under our revolving credit facility to the extent of the realizable value of the ABL Collateral.

The lien ranking provisions of the indenture and other agreements relating to the Collateral securing the notes will limit the rights of holders of the notes with respect to certain Collateral, even during an event of default.

The rights of the holders of the notes with respect to the ABL Collateral will be substantially limited by the terms of the lien ranking agreements set forth in the indenture and the intercreditor agreement, even during an event of default. Under the indenture and the intercreditor agreement, at any time that obligations that have the benefit of the higher priority liens are outstanding, any actions that may be taken with respect to (or in respect of) the ABL Collateral, including the ability to cause the commencement of enforcement proceedings against the ABL Collateral and to control the conduct of such proceedings, and the approval of amendments to, releases of the ABL Collateral from the lien of, and waivers of past defaults under, such documents relating to the ABL Collateral, will be at the direction of the holders of the obligations secured by the first-priority liens, and the holders of the

Table of Contents

notes secured by lower priority liens may be adversely affected. See "Description of the Notes—Security," and "Description of the Notes—Modification of the Indenture and Security Documents."

Under the terms of the intercreditor agreement, at any time that obligations that have the benefit of the first-priority liens on the ABL Collateral are outstanding, if the holders of such indebtedness release their lien on the ABL Collateral for any reason whatsoever (other than any such release granted following the discharge of all such obligations with respect to the revolving credit facility), including, without limitation, in connection with any sale of assets permitted under the revolving credit facility, the second-priority security interest in such ABL Collateral securing the notes will be automatically and simultaneously released without any consent or action by the holders of the notes, subject to certain exceptions. The ABL Collateral so released will no longer secure our and the guarantors' obligations under the notes and the guarantees. In addition, because the holders of the indebtedness secured by first-priority liens in the ABL Collateral would control the disposition of the ABL Collateral, such holders could decide not to proceed against the ABL Collateral, regardless of whether there is a default under the documents governing such indebtedness or under the indenture governing the notes. In such event, the only remedy available to the holders of the notes would be to sue for payment on the notes and the related guarantees. The indenture and the intercreditor agreement contain certain provisions benefiting holders of indebtedness under our revolving credit facility, including provisions prohibiting the trustee and the notes collateral agent from objecting following the filing of a bankruptcy petition to a number of important matters regarding the ABL Collateral and the financing to be provided to us. After such filing, the value of the ABL Collateral could materially deteriorate and holders of the notes would be unable to raise an objection. In addition, the right of holders of obligations secured by first priority liens to foreclose upon and sell the ABL Collateral upon the occurrence of an event of default also would be subject to limitations under applicable bankruptcy laws if we or any of our subsidiaries become subject to a bankruptcy proceeding. The intercreditor agreement will give the holders of first priority liens on the ABL Collateral the right to access and use the ABL Collateral that also secures the notes on a second lien basis to allow those holders to protect the ABL Collateral and to process, store and dispose of the ABL Collateral.

The ABL Collateral will also be subject to any and all exceptions, defects, encumbrances, liens and other imperfections as may be accepted by the lenders under our revolving credit facility from time to time, whether on or after the date the notes and guarantees are issued. The existence of any such exceptions, defects, encumbrances, liens and other imperfections could adversely affect the value of the ABL Collateral securing the notes as well as the ability of the notes collateral agent to realize or foreclose on the ABL Collateral. See "Description of the Notes—Security—Intercreditor Agreement."

The value of the Collateral securing the notes may not be sufficient to satisfy our obligations under the notes.

No appraisal of the value of the Collateral has been made in connection with this offering, and the fair market value of the Collateral will be subject to fluctuations based on factors that include, among others, general economic conditions and similar factors. The amount to be received upon a sale of the Collateral would be dependent on numerous factors including, but not limited to, the actual fair market value of the Collateral at such time, the timing and the manner of the sale and the availability of buyers. By its nature, portions of the Collateral may be illiquid and may have no readily ascertainable market value. In the event of a foreclosure, liquidation, bankruptcy or similar proceeding, the Collateral may not be sold in a timely or orderly manner and the proceeds from any sale or liquidation of this Collateral may not be sufficient to pay our obligations under the notes.

To the extent that pre-existing liens, liens permitted under the indenture and other rights, including liens on excluded assets, such as those securing purchase money obligations and capital lease obligations granted to other parties (in addition to the holders of obligations secured by first-priority liens), encumber any of the Collateral securing the notes and the guarantees, those parties have or may

exercise rights and remedies with respect to the Collateral that could adversely affect the value of the Collateral and the ability of the notes collateral agent, the trustee under the indenture or the holders of the notes to realize or foreclose on the Collateral.

In addition, the indenture governing the notes permits us, subject to compliance with certain financial tests, to issue additional secured debt, including debt secured equally and ratably by the same assets pledged for the benefit of the holders of the notes. This would reduce amounts payable to holders of the notes from the proceeds of any sale of the Collateral. There may not be sufficient Collateral to pay off any additional amounts we may borrow under our revolving credit facility or any additional indebtedness we may issue that will be secured equally and ratably together with the notes. Consequently, liquidating the Collateral securing the notes and the guarantees may not result in proceeds in an amount sufficient to pay any amounts due under the notes after also satisfying the obligations to pay any creditors with prior liens. If the proceeds of any sale of Collateral were not sufficient to repay all amounts due on the notes, the holders of the notes (to the extent not repaid from the proceeds of the sale of the Collateral) would have only an unsecured, unsubordinated claim against our and the subsidiary guarantors' remaining assets.

The Collateral securing the notes may be diluted under certain circumstances.

The indenture governing the notes and our revolving credit agreement permit us to incur, and our domestic subsidiaries to guarantee, additional indebtedness subject to our compliance with the restrictive covenants in such documents. Any issuance of such additional indebtedness that is secured by the same security interests, and with the same priority, would dilute the value of the Collateral to the extent of the aggregate principal amount of such additional debt issued.

We will in most cases have control over the Collateral, and the sale of particular assets by us could reduce the pool of assets securing the notes and the guarantees.

The collateral documents will allow us to remain in possession of, retain exclusive control over, freely operate, and collect, invest and dispose of any income from, the Collateral securing the notes and the guarantees. In addition, we will not be required to comply with all or any portion of Section 314(d) of the Trust Indenture Act of 1939 if we determine, in good faith based on advice of counsel, that, under the terms of that Section and/or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including "no action" letters or exemptive orders, all or such portion of Section 314(d) of the Trust Indenture Act is inapplicable to the released Collateral. For example, so long as no default or event of default under the indenture would result therefrom and such transaction would not violate the Trust Indenture Act, we may, among other things, without any release or consent by the indenture trustee, conduct ordinary course activities with respect to the Collateral, such as selling, factoring, abandoning or otherwise disposing of Collateral and making ordinary course cash payments (including repayments of indebtedness). See "Description of the Notes—Certain Covenants—Limitation on Asset Sales."

There are circumstances other than repayment or discharge of the notes under which the Collateral securing the notes and guarantees will be released automatically, without your consent or the consent of the trustee.

Under various circumstances, Collateral may be released, including:

•: to enable the sale, transfer or other disposal of such Collateral in a transaction not prohibited under the indenture or the revolving credit facility, including the sale of any entity in its entirety that owns or holds such Collateral;
•: with respect to Collateral held by a guarantor, upon the release of such guarantor from its guarantee as permitted by the indenture; and

Table of Contents

•: with respect to any ABL Collateral, upon any release by the lenders under our revolving credit facility of their first-priority security interest in such ABL Collateral (other than any such release granted following the discharge of the obligations with respect to the revolving credit facility).

In addition, the guarantee of a subsidiary guarantor will be released in connection with a sale of such subsidiary guarantor in a transaction not prohibited by the indenture.

The indenture also permits us, under certain circumstances, to designate one or more of our restricted subsidiaries that is a guarantor of the notes as an unrestricted subsidiary. If we designate a subsidiary guarantor as an unrestricted subsidiary as permitted by the indenture, all of the liens on any Collateral owned by such subsidiary or any of its subsidiaries and any guarantees of the notes by such subsidiary or any of its subsidiaries will be released under the indenture but not under the revolving credit facility. Designation of an unrestricted subsidiary will reduce the aggregate value of the Collateral securing the notes to the extent that liens on the assets of the unrestricted subsidiary and its subsidiaries are released. In addition, the creditors of the unrestricted subsidiary and its subsidiaries will have a senior claim on the assets of such unrestricted subsidiary and its subsidiaries. See "Description of the Notes—Security—Release of Collateral."

There are certain other categories of property that are also excluded from the Collateral.

Certain categories of assets are excluded from the Collateral. Excluded assets include, among certain other assets, any interest in any owned real property if the greater of cost or book value thereof is less than $2.5 million, leasehold interests with annual rents below $2.5 million, assets and capital stock the pledge of which would violate applicable law or contract, certain letter of credit rights, assets held outside of the United States, assets of foreign subsidiaries, the assets of our non-guarantor subsidiaries and non-subsidiary equity investees, capital stock and other securities of our subsidiaries and equity investees and the proceeds from any of the foregoing. See "Description of the Notes—Security." If an event of default occurs and the notes are accelerated, the notes and the guarantees will rank equally with the holders of other unsubordinated and unsecured indebtedness of the relevant entity with respect to such excluded property.

Rights of holders of the notes in the Collateral may be adversely affected by the failure to perfect security interests in the Collateral.

Applicable law requires that a security interest in certain tangible and intangible assets can only be properly perfected and its priority retained through certain actions undertaken by the secured party. The liens in the Collateral securing the notes may not be perfected with respect to the claims of the notes if the notes collateral agent does not take the actions necessary to perfect any of these liens. There can be no assurance that the notes collateral agent will have taken all actions necessary to create properly perfected security interests, which may result in the loss of the priority of the security interest in favor of the holders of the notes to which they would otherwise have been entitled. There can be no assurance as to when all such additional actions necessary to perfect the liens on or security interests in the Collateral securing the notes will be completed and, to the extent a lien on or security interest in certain Collateral is perfected following the date of issuance of the notes, it might be voidable by a trustee in bankruptcy.

In addition, applicable law requires that certain property and rights acquired after the grant of a general security interest, such as real property, equipment subject to a certificate of title and certain proceeds, can only be perfected at the time such property and rights are acquired and identified. There can be no assurance that the trustee or the notes collateral agent will monitor, or that we will inform the trustee or notes collateral agent of, the future acquisition of property and rights that constitute Collateral, and that the necessary action will be taken to properly perfect the security interest in such after-acquired Collateral. Neither the Trustee nor the notes collateral agent has an obligation to

Table of Contents

monitor the acquisition of additional property or rights that constitute Collateral or the perfection of any security interest. Any such failure might result in the loss of the security interest in the Collateral or the priority of the security interest in favor of the notes against third parties.

Amendments to the existing mortgages and title insurance policies on our principal real properties intended to secure the notes and the guarantees were not in place at the time of the issuance of the old notes on March 24, 2011. Delivery of such mortgage amendments after the issuance of the old notes increases the risk that the liens granted by those mortgages could be avoided.

Amendments to the existing mortgages on our principal real properties increasing the respective amounts thereof to reflect the issuance of the old notes, to the extent that such amendments were necessary to perfect such security in the notes, were not in place at the time of the issuance of the old notes on March 24, 2011. In addition, we did not have amendments to the title insurance policies on our principal real properties in place at the time of the issuance of the old notes to insure, among other things, (i) loss resulting from the entity represented by us to be the owner thereof not holding fee title or a valid leasehold interest in such properties and such interest being encumbered by unpermitted liens and (ii) the validity and first lien priority of the mortgages granted to the notes collateral agent for the benefit of the holders of the notes.

Within 30 days after the issuance of the old notes on March 24, 2011, we completed the filing of amendments to the mortgages and other similar actions required in connection with the perfection of security interests in each of our real properties having a cost or book value (whichever is greater) in excess of $2.5 million, and we then provided to the notes collateral agent amendments to the existing mortgagee title insurance policies (or new mortgage title insurance policies) reflecting such mortgage amendments on such properties. However, if we or any guarantor were to become subject to a bankruptcy proceeding in the future, any mortgage amendment delivered after the issuance of the old notes would face a greater risk of being invalidated than if we had delivered it at such issue date.

Any future pledge of Collateral might be avoidable in bankruptcy.

Any future pledge of Collateral in favor of the notes collateral agent, including pursuant to security documents delivered after the date of the indenture governing the notes, might be avoidable by the pledgor (as debtor in possession) or by its trustee in bankruptcy if certain events or circumstances exist or occur, including if the pledgor were insolvent at the time of the pledge, the pledge permits the holders of the notes to receive a greater recovery than if the pledge had not been given and a bankruptcy proceeding in respect of the pledgor is commenced within 90 days following the pledge, or, in certain circumstances, a longer period. As more fully described above, certain of the assets securing the notes were not subject to a valid and perfected security interest on the issue date of the old notes, but we provided to the notes collateral agent a valid and perfected security interest on such assets to secure the notes after the issue date.

The Collateral is subject to casualty risks.

We have agreed to maintain insurance on the Collateral and otherwise insure against hazards in a manner appropriate and customary for our business. There are, however, certain losses that may be either uninsurable or not economically insurable, in whole or in part. Insurance proceeds may not compensate us fully for our losses. If there were a complete or partial loss of any of the Collateral, the insurance proceeds might not be sufficient to satisfy all of the secured obligations, including the notes and the guarantees. In the event of a total or partial loss to any of the mortgaged facilities, certain items of equipment, fixtures and other improvements, and inventory may not be easily replaced. Accordingly, even though there may be insurance coverage, the extended period needed to manufacture or construct replacement for such items could cause significant delays.

Table of Contents

In the event of our bankruptcy, the ability of the holders of the notes to realize upon the Collateral will be subject to certain bankruptcy law limitations.

The ability of holders of the notes to realize upon the Collateral will be subject to certain bankruptcy law limitations in the event of our bankruptcy. Under applicable U.S. federal bankruptcy laws, secured creditors are prohibited from, among other things, repossessing their security from a debtor in a bankruptcy case without bankruptcy court approval and may be prohibited from retaining security repossessed by such creditors without bankruptcy court approval. Moreover, applicable federal bankruptcy laws generally permit the debtor to continue to retain collateral, including cash collateral, even though the debtor is in default under the applicable debt instruments, provided that the secured creditor is given "adequate protection."

The secured creditor is entitled to "adequate protection" to protect the value of the secured creditor's interest in the Collateral as of the commencement of the bankruptcy case, but the adequate protection actually provided to a secured creditor may vary according to the circumstances. Adequate protection may include cash payments or the granting of additional security if and at such times as the court, in its discretion and at the request of such creditor, determines after notice and a hearing that the Collateral has diminished in value as a result of the imposition of the automatic stay of repossession of such Collateral or the debtor's use, sale or lease of such Collateral during the pendency of the bankruptcy case. In view of the lack of a precise definition of the term "adequate protection" and the broad discretionary powers of a U.S. bankruptcy court, it is uncertain whether or when the notes collateral agent could foreclose upon or sell the Collateral or whether or to what extent holders of notes would be compensated for any delay in payment or loss of value of the Collateral through the requirement of "adequate protection." Moreover, the notes collateral agent may need to evaluate the impact of the potential liabilities before determining to foreclose on Collateral consisting of real property, if any, because secured creditors that hold a security interest in real property may be held liable under environmental laws for the costs of remediating or preventing the release or threatened releases of hazardous substances at such real property. Consequently, the notes collateral agent may decline to foreclose on such Collateral or exercise remedies available in respect thereof if it does not receive indemnification to its satisfaction from the holders of the notes.

The waiver in the intercreditor agreement of rights of marshaling may adversely affect the recovery rates of holders of the notes in a bankruptcy or foreclosure scenario.

The notes and the guarantees are secured on a second-priority lien basis by the ABL Collateral. The intercreditor agreement provides that, at any time obligations having the benefit of the first-priority liens on the ABL Collateral are outstanding, the holders of the notes, the trustee under the indenture governing the notes and the notes collateral agent may not assert or enforce any right of marshaling accorded to a junior lienholder as against the holders of such indebtedness secured by first-priority liens in the ABL Collateral. Without this waiver of the right of marshaling, holders of such indebtedness secured by first-priority liens in the ABL Collateral would likely be required to liquidate collateral on which the notes did not have a lien, if any, prior to liquidating the ABL Collateral, thereby maximizing the proceeds of the ABL Collateral that would be available to repay our obligations under the notes. As a result of this waiver, the proceeds of sales of the ABL Collateral could be applied to repay any indebtedness secured by first-priority liens in the ABL Collateral before applying proceeds of other collateral securing indebtedness, and the holders of notes may recover less than they would have if such proceeds were applied in the order most favorable to the holders of the notes.

Table of Contents

In the event of a bankruptcy of us or any of the guarantors, holders of the notes may be deemed to have an unsecured claim to the extent that our obligations in respect of the notes exceed the fair market value of the Collateral securing the notes.

In any bankruptcy proceeding with respect to us or any of the Guarantors, it is possible that the bankruptcy trustee, the debtor-in-possession or competing creditors will assert that the fair market value of the Collateral with respect to the notes on the date of the bankruptcy filing was less than the then-current principal amount of the notes. Upon a finding by the bankruptcy court that the notes were under-collateralized, the claims in the bankruptcy proceeding with respect to the notes would be bifurcated between a secured claim in an amount equal to the value of the Collateral and an unsecured claim with respect to the remainder of its claim which would not be entitled to the benefits of security in the Collateral. Other consequences of a finding of under-collateralization would be, among other things, a lack of entitlement on the part of the notes to receive post-petition interest and a lack of entitlement on the part of the unsecured portion of the notes to receive "adequate protection" under federal bankruptcy laws. In addition, if any payments of post-petition interest had been made at any time prior to such a finding of under-collateralization, those payments would be recharacterized by the bankruptcy court as a reduction of the principal amount of the secured claim with respect to the notes.

It may be difficult to realize the value of the Collateral pledged to secure the notes.

Our and the Guarantors' obligations under the notes and the guarantees are secured only by the Collateral described in this prospectus. The notes collateral agent's ability to foreclose on the Collateral on your behalf may be subject to perfection, the consent of third parties, priority issues, state law requirements and practical problems associated with the realization of the notes collateral agent's security interest in the Collateral, including cure rights, foreclosing on the Collateral within the time periods permitted by third parties or prescribed by laws, statutory rights of redemption, and the effect of the order of foreclosure. The consents of any third parties and approvals by governmental entities may not be given when required to facilitate a foreclosure on such assets. Accordingly, the notes collateral agent may not have the ability to foreclose upon the facilities or assume or transfer the right to operate the facilities. Foreclosure on the Collateral may therefore not be sufficient to acquire all facility assets necessary for operations or to make all payments on the notes.

In addition, our business requires numerous federal, state and local permits. Continued operation of those facilities that are part of the Collateral depends on the maintenance of such permits. Our business is subject to substantial regulations and permitting requirements and may be adversely affected if we were unable to comply with existing regulations or requirements or changes in applicable regulations or requirements. In the event of foreclosure, the transfer of such permits may require us to incur significant cost and expense. Further, the applicable governmental authorities might not consent to the transfer of all such permits. If the regulatory approvals required for such transfers were not obtained or were delayed, the foreclosure might be delayed, a temporary shutdown of operations might result and the value of the Collateral might be significantly decreased.

The value of the Collateral securing the notes may not be sufficient to secure post-petition interest.

In the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding against us or the Guarantors, holders of the notes will only be entitled to post-petition interest under the United States Bankruptcy Code to the extent that the value of their security interest in the Collateral is greater than their pre-bankruptcy claim. Holders of the notes that have a security interest in Collateral with a value equal or less than their pre-bankruptcy claim will not be entitled to post-petition interest under the United States Bankruptcy Code. No appraisal of the fair market value of the Collateral has been prepared in connection with the offering of the old notes or this exchange offer and therefore the value of the noteholders' interest in the Collateral may not equal or exceed the principal amount of the notes.

Table of Contents

A court could subordinate or void the obligations under our subsidiaries' guarantees.

Under the U.S. federal bankruptcy laws and comparable provisions of state fraudulent conveyance laws, a court could void obligations under the guarantees by our subsidiaries, subordinate those obligations to other obligations of the Guarantors or require you to repay any payments made pursuant to the guarantees, if:

(1)

fair consideration or reasonably equivalent value was not received in exchange for the obligation; and

(2)

at the time the obligation was incurred, the obligor:

•: was insolvent or rendered insolvent by reason of the obligation;
•: was engaged in a business or transaction for which its remaining assets constituted unreasonably small capital; or
•: intended to incur, or believed that it would incur, debts beyond its ability to pay them as the debts matured.

The measure of insolvency for these purposes will depend upon the law of the jurisdiction being applied. Generally, however, a company will be considered insolvent if:

•: the sum of its debts, including contingent liabilities, is greater than the saleable value of all of its assets at a fair valuation;
•: the present fair saleable value of its assets is less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and matured; or
•: it could not pay its debts as they become due.

Moreover, regardless of solvency, a court might void the guarantees, or subordinate the guarantees, if it determined that the transaction was made with intent to hinder, delay or defraud creditors.

Each guarantee by our subsidiaries contains a provision intended to limit the Guarantor's liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent transfer. This provision, however, may not be effective to protect the guarantees by our subsidiaries from attack under fraudulent transfer law or may reduce the Guarantor's obligations to an amount that effectively makes the subsidiary guarantee worthless. In a recent Florida bankruptcy case, this kind of provision was found ineffective to protect the guarantees. If one or more of the guarantees were voided or subordinated, after providing for all prior claims, there might not be sufficient assets remaining to satisfy the claims of the holders of the notes.

The indenture requires that substantially all of our future domestic subsidiaries also must guarantee the notes in the future. These considerations will also apply to any such guarantees.

We may not have the ability to repurchase the notes upon a change of control as required by the indenture.

Upon the occurrence of a change of control (as defined in the indenture), the indenture requires us to offer to purchase all of the then outstanding notes at 101% of their principal amount plus accrued and unpaid interest to the date of repurchase. However, upon such a change of control, we may not have sufficient funds available to repurchase all of the notes tendered pursuant to this requirement. In addition, our revolving credit facility limits, and our future credit facilities may limit, our ability to repurchase any of the notes unless certain requirements are satisfied or the lenders thereunder consent. Our failure to repurchase the notes would be a default under the indenture, which would, in turn, be a default under our revolving credit facility and, potentially, other debt. If any debt

Table of Contents

were to be accelerated, we may be unable to repay these amounts and make the required repurchase of the notes. See "Description of the Notes—Change of Control."

The market valuation of the notes may be exposed to substantial volatility.

A real or perceived economic downturn or higher interest rates could cause a decline in the market price of the notes and thereby negatively impact the market for the notes. Because the notes may be thinly traded, it may be more difficult to sell and accurately value the notes. In addition, as has recently been evident in the global financial markets, the economic slowdown and the uncertainty over its breadth, depth and duration, the entire high-yield bond market can experience sudden and sharp price swings, which can be exacerbated by large or sustained sales by major investors in the notes, a high-profile default by another issuer, or a change in the market's psychology regarding high-yield notes. Moreover, if one of the major rating corporations were to lower its credit rating of the notes, the market price of the notes would likely decline.

There is no established trading market for the notes. If an actual trading market does not develop for the notes, you may not be able to resell them quickly for the price that you paid or at all.

There is no established trading market for the notes and we do not intend to apply for the notes to be listed on any securities exchange or to arrange for any quotation on any automated dealer quotation systems. The initial purchasers have advised us that they intend to make a market in the notes, but they are not obligated to do so. Each initial purchaser may discontinue any market making in the notes and at any time, in its sole discretion. As a result, we cannot assure you as to the liquidity of any trading market for the notes. We also cannot assure you that you will be able to sell your notes at a particular time or at all, or that the prices that you receive when you sell them will be favorable. If no active trading market develops, you may not be able to resell your notes at their fair market value, or at all.

The liquidity of, and trading market for, the notes may also be adversely affected by, among other things:

•: prevailing interest rates;
•: our operating performance and financial condition;
•: the interest of securities dealers in making a market; and
•: the market for similar securities.

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

There is a possibility that the IRS may not treat the old notes issued on March 24, 2011 and exchanged for new notes pursuant to this exchange offer as fungible with the original 2016 notes issued under the indenture on August 14, 2009.

We intend, for U.S. federal income tax purposes, to treat the issuance of the old notes on March 24, 2011 as a "qualified reopening" of the issuance under the indenture of the original 2016 notes on August 14, 2009. Accordingly, we intend to treat, for U.S. federal income tax purposes, the old notes and the new notes issued in exchange for old notes pursuant to this exchange offer as having the same issue date, issue price and adjusted issue price as the original 2016 notes, and therefore as having been issued with the same amount of original issue discount, or "O.I.D.," as the original 2016 notes. However, we can give no assurance that the IRS will not challenge this position. If the IRS were

Table of Contents

successful, the old notes issued on March 24, 2011 and exchanged for new notes pursuant to this exchange offer would not be treated as part of the same issuance as the original 2016 notes and therefore would not be fungible with such original 2016 notes. Nevertheless, a holder that purchased old notes on March 24, 2011 at the initial offering price of 104.5% of their stated principal amount (plus accrued interest), and which exchanges such old notes for new notes pursuant to this exchange offer, should still be deemed to have purchased its notes at a "premium" and should therefore not be required to include any O.I.D. in gross income. See "U.S. Federal Income and Estate Tax Considerations" elsewhere in this prospectus.

Risks Affecting Both Our Environmental Services and Energy and Industrial Services Businesses

Our businesses are subject to operational and safety risks.

Provision of both environmental services and energy and industrial services to our customers involves risks such as equipment defects, malfunctions and failures, and natural disasters, which could potentially result in releases of hazardous materials, injury or death of our employees, or a need to shut down or reduce operation of our facilities while remedial actions are undertaken. Our employees often work under potentially hazardous conditions. These risks expose us to potential liability for pollution and other environmental damages, personal injury, loss of life, business interruption, and property damage or destruction. We must also maintain a solid safety record in order to remain a preferred supplier to our major customers.

While we seek to minimize our exposure to such risks through comprehensive training programs, vehicle and equipment maintenance programs and insurance, such programs and insurance may not be adequate to cover all of our potential liabilities and such insurance may not in the future be available at commercially reasonable rates. If we were to incur substantial liabilities in excess of policy limits or at a time when we were not able to obtain adequate liability insurance on commercially reasonable terms, our business, results of operations and financial condition could be adversely affected to a material extent. Furthermore, should our safety record deteriorate, we could be subject to a potential reduction of revenues from our major customers.

Our businesses are subject to significant competition.

We compete with a large number of companies, which range from large public companies to small operators that provide most of the same or similar services to those we offer. The 2008-2010 downturn in economic conditions, particularly with respect to manufacturing and oil and gas exploration and production, caused increased competition for market share. This competition resulted and could further result in lower prices and reduced gross margins for our services and negatively affect our ability to grow or sustain our current revenue and profit levels in the future.

Our businesses are subject to numerous statutory and regulatory requirements, which may increase in the future.

Our businesses are subject to numerous statutory and regulatory requirements, and our ability to continue to hold licenses and permits required for our businesses is subject to maintaining satisfactory compliance with such requirements. These requirements may increase in the future as a result of statutory and regulatory changes. Although we are very committed to compliance and safety, we may not, either now or in the future, be in full compliance at all times with such statutory and regulatory requirements. Consequently, we could be required to incur significant costs to maintain or improve our compliance with such requirements.

Seasonality makes it harder for us to manage our businesses and for investors to evaluate our performance.

Our business operations are affected by seasonal fluctuations due to weather and budgetary cycles influencing the timing of customers' spending for our services. Typically during the first quarter of each calendar year, there is less demand for environmental remediation due to weather-related reasons, particularly in northern and midwestern United States and in Canada, and an increased possibility of unplanned weather-related plant shutdowns. Conversely, because a large portion of our energy and industrial services business is carried out in Western Canada and involves moving heavy equipment, our ability to provide such services is dependent on weather conditions. Thawing in the spring renders many secondary roads incapable of supporting heavy equipment, and extremely cold weather in the winter season or wet weather during any season can limit our ability to provide timely services. As a result, the operating performance of our energy and industrial services business also tends to be seasonal (with higher revenues during the first quarter of each year and reduced revenues during the second quarter) and may be negatively impacted by adverse weather conditions during any quarter. This seasonality makes it harder for us to manage our businesses and for investors to evaluate our performance.

Future conditions might require us to make substantial write-downs in our assets, which would adversely affect our balance sheet and results of operations.

Periodically, we review our long-lived tangible and intangible assets other than goodwill for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. We also test our goodwill assets for impairment at least annually on December 31, or when events or changes in the business environment indicate that the carrying value of a reporting unit may exceed its fair value. At the end of each of 2010, 2009 and 2008, we determined that no asset write-downs were required; however, if conditions in either the environmental services or energy and industrial services businesses were to deteriorate significantly, we could determine that certain of our assets were impaired and we would then be required to write-off all or a portion of our costs for such assets. Any such significant write-offs would adversely affect our balance sheet and results of operations.

Fluctuations in foreign currency exchange rates could affect our financial results.

We earn revenues, pay expenses, own assets and incur liabilities in countries using currencies other than the U.S. dollar. For the three months ended March 31, 2011, we recorded 42% of our revenues outside of the United States, primarily in Canada. Because our consolidated financial statements are presented in U.S. dollars, we must translate revenues, income and expenses as well as assets and liabilities into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, increases or decreases in the value of the U.S. dollar against other currencies in countries where we operate will affect our results of operations and the value of balance sheet items denominated in foreign currencies. These risks are non-cash exposures. We manage these risks through normal operating and financing activities. We cannot be certain, however, that we will be successful in reducing the risks inherent in exposures to foreign currency fluctuations.

We may make further acquisitions in the future with the goal of expanding our business. However, we may be unable to complete such transactions and, if completed, such transactions may not improve our business or may pose significant risks and could have a negative effect on our operations.

We have in the past significantly increased the size of our Company and the types of services we offer to our customers through acquisitions. Since December 31, 2005, we have acquired two public companies (Eveready Inc. in July 2009, and Peak Energy Services Ltd. in June 2011) and eight private companies from August 2006 through April 2010. We may in the future make additional acquisitions,

Table of Contents

including our proposed acquisition of an additional private company and substantially all of the assets of a division of a Canadian public company for which we signed, in May and June 2011, acquisition agreements providing for a total combined purchase price of approximately $100.0 million. Each proposed acquisition is subject to customary closing conditions and no assurance can be given that either or both of the proposed acquisitions will be consummated. Except for those two proposed additional acquisitions, we may not be able to identify and negotiate the potential acquisition of suitable acquisition candidates on terms and conditions favorable to us.

Our ability to achieve the benefits from any potential future acquisitions, including cost savings and operating efficiencies, depends in part on our ability to successfully integrate the operations of such acquired businesses with our operations. The integration of acquired businesses and other assets may require significant management time and company resources that would otherwise be available for the ongoing management of our existing operations. While we have had success integrating our prior acquisitions described above, each acquisition presents unique objectives, circumstances and challenges.

Any properties or facilities that we acquire may also be subject to unknown liabilities, such as undisclosed environmental contamination, for which we may have no recourse, or only limited recourse, to the former owners of such properties. As a result, if a liability were asserted against us based upon ownership of an acquired property, we might be required to pay significant sums to settle it, which could adversely affect our financial results and cash flow.

If we are unable to successfully integrate the respective businesses and operations of Peak Energy Services Ltd., or "Peak," and any additional companies we may hereafter acquire and realize synergies in the expected time frame, our future results would be adversely affected.

Our integration of the respective businesses and operations of Peak and any additional companies we may hereafter acquire into our business and operations will require implementation of appropriate operations, management and financial reporting systems and controls. We may experience difficulties in effectively implementing these and other systems and operations, and the integration process may be costly and time-consuming. Such integration will require the focused attention of our and the acquired company's management teams, including a significant commitment of their time and resources. The need for our respective managements to focus on integration matters could have a material and adverse impact on the revenues and operating results of the combined company. The success of any such acquisition will depend, in part, on the combined company's ability to realize the anticipated benefits from combining the businesses of the acquired company and Clean Harbors through cost reductions in overhead, greater efficiencies, increased utilization of support facilities and the adoption of mutual best practices. To realize these anticipated benefits, however, the businesses of the acquired company and Clean Harbors must be successfully combined.

If the combined company is not able to achieve these objectives, the anticipated benefits to us of any such acquisition may not be realized fully or at all or may take longer to realize than expected. It is possible that the integration process could result in the loss of key employees, as well as the disruption of each company's ongoing businesses, failure to implement the business plan for the combined business, unanticipated issues in integrating manufacturing, logistics, information, communications and other systems, unanticipated changes in applicable laws and regulations, operating risks inherent in our business or inconsistencies in standards, controls, procedures and policies or other unanticipated issues, expenses and liabilities, any or all of which could adversely affect our ability to maintain relationships with our and the acquired companies customers and employees or to achieve the anticipated benefits of the acquisitions. These integration matters could have a material adverse effect on our business.

Risks Particularly Affecting Our Environmental Services Business

We assumed significant environmental liabilities as part of our past acquisitions and may assume additional such liabilities as part of future acquisitions. Our financial condition and results of operations would be adversely affected if we were required to pay such liabilities more rapidly or in greater amounts than we now estimate or may estimate in connection with future acquisitions.

We have accrued environmental liabilities valued as of March 31, 2011, at $172.6 million, substantially all of which we assumed in connection with our acquisitions of substantially all of the assets of the Chemical Services Division, or "CSD," of Safety-Kleen Corp. in 2002, Teris LLC in 2006, and one of two solvent recycling facilities we purchased from Safety-Kleen Systems, Inc. in 2008. We calculate our environmental liabilities on a present value basis in accordance with generally accepted accounting principles, which take into consideration both the amount of such liabilities and the timing when it is projected that we will be required to pay such liabilities. We anticipate our environmental liabilities will be payable over many years and that cash flows generated from our operations will generally be sufficient to fund the payment of such liabilities when required. However, events not now anticipated (such as future changes in environmental laws and regulations or their enforcement) could require that such payments be made earlier or in greater amounts than now estimated, which could adversely affect our financial condition and results of operations.

We may also assume additional environmental liabilities as part of further acquisitions. Although we will endeavor to accurately estimate and limit environmental liabilities presented by the businesses or facilities to be acquired, some liabilities, including ones that may exist only because of the past operations of an acquired business or facility, may prove to be more difficult or costly to address than we then estimate. It is also possible that government officials responsible for enforcing environmental laws may believe an environmental liability is more significant than we then estimate, or that we will fail to identify or fully appreciate an existing liability before we become legally responsible to address it.

If we are unable to obtain at reasonable cost the insurance, surety bonds, letters of credit, and other forms of financial assurance required for our facilities and operations, our business and results of operations would be adversely affected.

We are required to provide substantial amounts of financial assurance to governmental agencies for closure and post-closure care of our licensed hazardous waste treatment facilities should those facilities cease operation, and we are also occasionally required to post surety, bid and performance bonds in connection with certain projects. As of March 31, 2011, our total estimated closure and post-closure costs requiring financial assurance by regulators were $321.3 million for our U.S. facilities and $23.1 million for our Canadian facilities. We have obtained all of the required financial assurance for our facilities from a qualified insurance company, Zurich Insurance N.A., and its affiliated companies. The closure and post-closure obligations of our U.S. facilities are insured by an insurance policy written by Steadfast Insurance Company (a unit of Zurich Insurance N.A.), which will expire in 2013. Our Canadian facilities utilize surety bonds provided through Zurich Insurance Company (Canada), which expire at various dates throughout 2011. In connection with obtaining such insurance and surety bonds, we have provided to Steadfast Insurance Company $73.5 million of letters of credit which we obtained from our lenders under our revolving credit agreement.

Our ability to continue operating our facilities and conducting our other operations would be adversely affected if we became unable to obtain sufficient insurance, surety bonds, letters of credit and other forms of financial assurance at reasonable cost to meet our regulatory and other business requirements. The availability of insurance, surety bonds, letters of credit and other forms of financial assurance is affected by our insurers', sureties' and lenders' assessment of our risk and by other factors outside of our control such as general conditions in the insurance and credit markets.

The environmental services industry in which we participate is subject to significant economic and business risks.

Our future operating results of our environmental services business may be affected by such factors as our ability to utilize our facilities and workforce profitably in the face of intense price competition, maintain or increase market share in an industry which has experienced significant downsizing and consolidation, realize benefits from cost reduction programs, generate incremental volumes of waste to be handled through our facilities from existing and acquired sales offices and service centers, obtain sufficient volumes of waste at prices which produce revenue sufficient to offset the operating costs of the facilities, minimize downtime and disruptions of operations, and develop our field services business. In particular, economic downturns or recessionary conditions in North America, and increased outsourcing by North American manufacturers to plants located in countries with lower wage costs and less stringent environmental regulations, have adversely affected and may in the future adversely affect the demand for our services. Our hazardous and industrial waste management business is also cyclical to the extent that it is dependent upon a stream of waste from cyclical industries such as the chemical and petrochemical, primary metals, paper, furniture and aerospace industries. If those cyclical industries slow significantly, the business that we receive from those industries is likely to slow.

A significant portion of our environmental services business depends upon the demand for cleanup of major spills and other remedial projects and regulatory developments over which we have no control.

Our operations are significantly affected by the commencement and completion of cleanup of major spills and other events, customers' decisions to undertake remedial projects, seasonal fluctuations due to weather and budgetary cycles influencing the timing of customers' spending for remedial activities, the timing of regulatory decisions relating to hazardous waste management projects, changes in regulations governing the management of hazardous waste, secular changes in the waste processing industry towards waste minimization and the propensity for delays in the demand for remedial services, and changes in the myriad of governmental regulations governing our diverse operations. We do not control such factors and, as a result, our revenue and income can vary significantly from quarter to quarter, and past financial performance for certain quarters may not be a reliable indicator of future performance for comparable quarters in subsequent years. In particular, our participation in oil spill response efforts in both the Gulf of Mexico and Michigan generated third party revenues for the year ended December 31, 2010 of $253.0 million, which accounted for approximately 15% of total revenues. We cannot expect such event revenue to reoccur in 2011.

The extensive environmental regulations to which we are subject may increase our costs and potential liabilities and limit our ability to expand our facilities.

Our operations and those of others in the environmental services industry are subject to extensive federal, state, provincial and local environmental requirements in both the United States and Canada, including those relating to emissions to air, discharged wastewater, storage, treatment, transport and disposal of regulated materials and cleanup of soil and groundwater contamination. For example, any failure to comply with governmental regulations governing the transport of hazardous materials could negatively impact our ability to collect, process and ultimately dispose of hazardous wastes generated by our customers. While increasing environmental regulation often presents new business opportunities for us, it often also results in increased operating and compliance costs. Efforts to conduct our operations in compliance with all applicable laws and regulations, including environmental rules and regulations, require programs to promote compliance, such as training employees and customers, purchasing health and safety equipment, and in some cases hiring outside consultants and lawyers. Even with these programs, we and other companies in the environmental services industry are routinely faced with governmental enforcement proceedings, which can result in fines or other sanctions and require expenditures for remedial work on waste management facilities and contaminated sites. Certain of

Table of Contents

these laws impose strict and, under certain circumstances, joint and several liability on current and former owners and operators of facilities that release regulated materials or that generate those materials and arrange for their disposal or treatment at contaminated sites. Such liabilities can relate to required cleanup of releases of regulated materials and related natural resource damages.

From time to time, we have paid fines or penalties in governmental environmental enforcement proceedings, usually involving our waste treatment, storage and disposal facilities. Although none of these fines or penalties that we have paid in the past has had a material adverse effect upon us, we might in the future be required to make substantial expenditures as a result of governmental proceedings which would have a negative impact on our earnings. Furthermore, regulators have the power to suspend or revoke permits or licenses needed for operation of our plants, equipment, and vehicles based on, among other factors, our compliance record, and customers may decide not to use a particular disposal facility or do business with us because of concerns about our compliance record. Suspension or revocation of permits or licenses would impact our operations and could have a material adverse impact on our financial results. Although we have never had any of our facilities' operating permits revoked, suspended or non-renewed involuntarily, it is possible that such an event could occur in the future.

Some environmental laws and regulations impose liability and responsibility on present and former owners, operators or users of facilities and sites for contamination at such facilities and sites without regard to causation or knowledge of contamination. In the past, practices have resulted in releases of regulated materials at and from certain of our facilities, or the disposal of regulated materials at third party sites, which may require investigation and remediation, and potentially result in claims of personal injury, property damage and damages to natural resources. In addition, we occasionally evaluate various alternatives with respect to our facilities, including possible dispositions or closures. Investigations undertaken in connection with these activities may lead to discoveries of contamination that must be remediated, and closures of facilities might trigger compliance requirements that are not applicable to operating facilities. We are currently conducting remedial activities at certain of our facilities and paying a portion of the remediation costs at certain sites owned by third parties. While, based on available information, we do not believe these remedial activities will result in a material adverse effect upon our operations or financial condition, these activities or the discovery of previously unknown conditions could result in material costs.

In addition to the costs of complying with environmental laws and regulations, we incur costs defending against environmental litigation brought by governmental agencies and private parties. We are now, and may in the future be, a defendant in lawsuits brought by parties alleging environmental damage, personal injury, and/or property damage, which may result in our payment of significant amounts of liabilities.

Environmental and land use laws also impact our ability to expand our facilities. In addition, we are required to obtain governmental permits to operate our facilities, including all of our landfills. Even if we were to comply with all applicable environmental laws, there is no guarantee that we would be able to obtain the requisite permits from the applicable governmental authorities, and, even if we could, that any permit (and any existing permits we currently hold) will be extended or modified as needed to fit out business needs.

We may make further acquisitions from time to time in the future, and we have tried and will continue to try to evaluate and limit environmental risks and liabilities presented by businesses or facilities to be acquired prior to the acquisition. It is possible that some liabilities, including ones that may exist only because of the past operations of an acquired business or facility, may prove to be more difficult or costly to address than we anticipate. It is also possible that government officials responsible for enforcing environmental laws may believe an issue is more serious than we expect, or that we will fail to identify or fully appreciate an existing liability before we become legally responsible to address it.

Table of Contents

Some of the legal sanctions to which we could become subject could cause the suspension or revocation of a needed permit, or prevent us from or delay us in obtaining or renewing permits to operate or expand our facilities or harm our reputation.

Future changes in environmental regulations may require us to make significant capital expenditures.

Changes in environmental regulations can require us to make significant capital expenditures for our facilities. For example, in 2002, the United States Environmental Protection Agency, or "EPA," promulgated Interim Standards of the Hazardous Waste Combustor Maximum Achievable Control Technology, or "MACT," under the Federal Clean Air Act Amendments. These standards established new emissions limits and operational controls on all new and existing incinerators, cement kilns and light-weight aggregate kilns that burn hazardous waste-derived fuels. We have spent approximately $29.3 million since September 7, 2002 in order to bring our Deer Park, Texas and Aragonite, Utah incineration facilities, which we then acquired as part of the CSD assets, and our Kimball, Nebraska facility into compliance with the MACT regulations. Prior to our acquisition in August 2006 of our additional incineration facility in El Dorado, Arkansas, as part of our purchase of all the membership interests in Teris LLC, Teris had spent in excess of $30.0 million in order to bring that facility into compliance with the MACT standards. Future environmental regulations could cause us to make significant additional capital expenditures and adversely affect our results of operations and cash flow.

If our assumptions relating to expansion of our landfills should prove inaccurate, our results of operations and cash flow could be adversely affected.

When we include expansion airspace in our calculation of available airspace, we adjust our landfill liabilities to the present value of projected costs for cell closure and landfill closure and post-closure. It is possible that any of our estimates or assumptions could ultimately turn out to be significantly different from actual results. In some cases we may be unsuccessful in obtaining an expansion permit or we may determine that an expansion permit that we previously thought was probable has become unlikely. To the extent that such estimates, or the assumptions used to make those estimates, prove to be significantly different than actual results, or our belief that we will receive an expansion permit changes adversely in a significant manner, the landfill assets, including the assets incurred in the pursuit of the expansion, may be subject to impairment testing and lower prospective profitability may result due to increased interest accretion and depreciation or asset impairments related to the removal of previously included expansion airspace. In addition, if our assumptions concerning the expansion airspace should prove inaccurate, certain of our cash expenditures for closure of landfills could be accelerated and adversely affect our results of operations and cash flow.

Risks Particularly Affecting Our Energy and Industrial Services Business

A large portion of our energy and industrial services business is dependent on the oil and gas industry in Western Canada, and declines in oil and gas exploration and production in that region could adversely affect our business.

Our energy and industrial services business generates well over 50% of its total revenues from customers in the oil and gas industry operating in Western Canada, although a majority of the services we provide to such customers relate to industrial maintenance and oil and gas production and refining which are less volatile than oil and gas exploration. We also provide significant services to customers in the oil and gas industry operating in the United States or internationally and to customers in other industries such as forestry, mining and manufacturing. However, a major portion of the total revenues of our energy and industrial services business remains dependent on customers in the oil and gas industry operating in Western Canada.

Table of Contents

Accordingly, declines in the general level of oil and gas exploration, production and refining in Western Canada could potentially have significant adverse effects on our total revenues and profitability. Such declines occurred in 2008-2009 and could potentially occur in the future if reductions in the commodity prices of oil and gas result in reduced oil and gas exploration, production and refining. Such future declines could also be triggered by technological and regulatory changes, such as those affecting the availability and cost of alternative energy sources, and other changes in industry and worldwide economic and political conditions.

A significant part of our energy and industrial services business relates to the Alberta oil sands.

Many of our major customers in the oil and gas industry conduct a significant portion of their operations in the Alberta oil sands. The Alberta oil sands contain large oil deposits, but extraction may involve significantly greater cost and environmental concerns than conventional drilling. While we believe our major involvement in the oil sands region will provide significant future growth opportunities, such involvement also increases the risk that our business will be adversely affected if future economic activity in the Alberta oil sands were to decline considerably. Major factors that could cause such a decline might include a prolonged reduction in the commodity price of oil, future changes in environmental restrictions and regulations, and technological and regulatory changes relating to production of oil from the oil sands. Due to the downturn in worldwide economic conditions and in the commodity price of oil and gas which occurred in 2008 - 2009, certain of our customers have delayed a number of large projects in the planning and early development phases within the oil sands region. In addition, customers are revisiting their operating budgets and challenging their suppliers to reduce costs and achieve better efficiencies in their work programs.

Our energy and industrial services business is subject to workforce availability.

Our ability to provide high quality services to our customers is dependent upon our ability to attract and retain well-trained, experienced employees. Prior to 2008, the oil and gas services industry in Western Canada experienced for several years high demand for, and a corresponding shortage of, quality employees resulting, in particular, in employment of a significant number of employees from Eastern Canada on a temporary basis. Although the 2008-2009 downturn in the oil and gas industry increased the pool of quality employees available to meet our customer commitments, the subsequent improvement during 2010 of conditions in the oil and gas industry has increased, and any such improvement which may occur in the future would likely increase, competition for experienced employees.

(2): For all periods presented, "Adjusted EBITDA" consists of net income plus accretion of environmental liabilities, depreciation and amortization, net interest expense, and provision for income taxes. We also exclude loss on early extinguishment of debt, other expense (income), and income from discontinued operations, net of tax as these amounts are not considered part of usual business operations. See below for a reconciliation of Adjusted EBITDA to both net income and net cash from operating activities for the specified periods. Our management considers Adjusted EBITDA to be a measurement of performance which provides useful information to both management and investors. Adjusted EBITDA should not be considered an alternative to net income or other measurements under generally accepted accounting principles ("GAAP"). Because Adjusted EBITDA is not calculated identically by all companies, our measurements of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.

We use Adjusted EBITDA to enhance our understanding of our operating performance, which represents our views concerning our performance in the ordinary, ongoing and customary course of our operations. We historically have found it helpful, and believe that investors have found it helpful, to consider an operating measure that excludes expenses such as debt extinguishment and related costs relating to transactions not reflective of our core operations.

The information about our operating performance provided by this financial measure is used by our management for a variety of purposes. We regularly communicate Adjusted EBITDA results to our board of directors and discuss with the board our interpretation of such results. We also compare our Adjusted EBITDA performance against internal targets as a key factor in determining cash bonus compensation for executives and other employees, largely because we believe that this measure is indicative of how the fundamental business is performing and is being managed.

We also provide information relating to our Adjusted EBITDA so that analysts, investors and other interested persons have the same data that we use to assess our core operating performance. We believe that Adjusted EBITDA should be viewed only as a supplement to the GAAP financial information. We also believe, however, that providing this information in addition to, and together with, GAAP financial information permits the foregoing persons to obtain a better understanding of our core operating performance and to evaluate the efficacy of the methodology and information used by management to evaluate and measure such performance on a standalone and a comparative basis.

The following is a reconciliation of net income to Adjusted EBITDA for the following periods (in thousands):

DESCRIPTION OF REVOLVING CREDIT FACILITY

We have a revolving credit facility under which Bank of America, N.A. ("BofA") is the administrative and collateral agent (the "Agent") for the lenders and the issuing bank for letters of credit issued under the facility. Under the facility, as amended and restated effective May 31, 2011, Clean Harbors, Inc. (the "Company") has the right to borrow and obtain letters of credit for a combined maximum of up to $150.0 million (with a sub-limit of $140.0 million for letters of credit) and one of the Company's Canadian subsidiaries (the "Canadian Borrower") has the right to obtain up to $100.0 million of revolving loans and letters of credit (with a $75.0 million sub-limit for letters of credit). Availability under the U.S. line is subject to a borrowing base comprised of 85% of the eligible accounts receivable of the Company and its U.S. subsidiaries plus 100% of cash deposited in a controlled account with the Agent, and availability under the Canadian line is subject to a borrowing base comprised of 85% of the eligible accounts receivable of the Canadian Borrower and the Company's other Canadian subsidiaries plus 100% of cash deposited in a controlled account with the Agent's Canadian affiliate. The facility will expire on the first to occur of (i) May 31, 2016 or (ii) 60 days prior to the maturity of the Company's outstanding senior secured notes on August 15, 2016 if the notes have not by then been refinanced, defeased or reserved against the borrowing base on terms reasonably acceptable to the Agent.

Borrowings under the revolving credit facility will bear interest at a rate of, at the Company's option, either (i) LIBOR plus an applicable margin ranging from 1.75% to 2.25% per annum based primarily on the level of the Company's consolidated fixed charge coverage ratio for the most recently completed four fiscal quarter measurement period or (ii) BofA's base rate plus an applicable margin ranging from 0.75% to 1.25% per annum based primarily on such consolidated fixed charge coverage ratio. There is also an unused line fee, calculated on the then unused portion of the lenders' $250.0 million maximum commitments, ranging from 0.375% to 0.50% per annum of the unused commitment. For outstanding letters of credit, the Company will pay to the lenders a fee equal to the then applicable LIBOR margin described above, and to the issuing banks a standard fronting fee and customary fees and charges in connection with all amendments, extensions, draws and other actions with respect to letters of credit.

The Company's obligations under the revolving credit facility (including revolving loans and reimbursement obligations for outstanding letters of credit) are guaranteed by all of the Company's U.S. subsidiaries and secured by a first lien on substantially all of the Company's and its U.S. subsidiaries' accounts receivable and the proceeds thereof, as well as certain of the Company's and its U.S. subsidiaries' other assets which constitute "ABL Collateral" as defined in the indenture for the Company's outstanding senior secured notes. The Company's obligations under the revolving credit facility are also secured by a second lien on the assets of the Company and its U.S. subsidiaries which constitute "Notes Collateral" as defined in that indenture. The Canadian Borrower's obligations under the facility are guaranteed by substantially all of the Company's other Canadian subsidiaries and secured by a first lien on the accounts receivable of the Canadian Borrower and the other Canadian subsidiaries. The Company and its U.S. subsidiaries guarantee the obligations of the Canadian Borrower under the facility, but the Canadian Borrower and the other Canadian subsidiaries do not guarantee and are not otherwise responsible for the obligations of the Company and its U.S. subsidiaries.

Under the revolving credit facility, the Agent would have the right to exercise dominion over the Company's and its subsidiaries' cash (to the extent such cash represents the proceeds of accounts receivable) if the Company's "Liquidity" is less than the greater of (i) $37.5 million and (ii) 15% of the aggregate commitments of the lenders under the facility. Liquidity is defined as the sum of (a) the Company's then availability under the facility and (b) the lesser of (i) the Canadian Borrower's then availability under the facility and (ii) 30% of the lenders' aggregate commitments to the Canadian Borrower. If Liquidity should be less than the greater of (i) $31,250,000 and (ii) 12.5% of the aggregate

Table of Contents

commitments, the Company would be required to thereafter maintain a consolidated fixed charge coverage ratio of at least 1.00 to 1.00. In addition, the facility contains covenants which will restrict the Company's future ability to make certain types of acquisitions, debt prepayments, investments and distributions if Liquidity (on a pro forma basis after giving effect to such events) is less than between 35% and 15% (depending upon the type of restricted event) of the lenders' aggregate commitments or, if the Company's consolidated fixed charge coverage ratio for the most recently completed four fiscal quarters is at least 1.00 (or, in certain cases, 1.10) to 1.00, less than 17.5% or 15% (depending upon the type of restricted event) of the aggregate commitments.

THE EXCHANGE OFFER

Purpose and Effect of Exchange Offer; Registration Rights

We sold the $250.0 million principal amount of old notes on March 24, 2011 in an unregistered private placement to two investment banks that served as the initial purchasers. The initial purchasers then resold the old notes to investors under an offering circular dated March 21, 2011 in reliance on Rule 144A and Regulation S under the Securities Act.

As part of this private placement, we entered into a registration rights agreement with the initial purchasers on March 24, 2011. Under the registration rights agreement, we agreed to file the registration statement of which this prospectus is a part. We also agreed:

•: to use our commercially reasonable efforts to cause the registration statement to be declared effective under the Securities Act and to commence the exchange offer within 10 business days after such effective date;
•: to keep the exchange offer open for not less than 20 business days (or longer if required by applicable law) after the date notice of the registered exchange offer is mailed to the holders of the notes; and
•: to keep the registration statement continuously effective under the Securities Act for a period beginning after the date of completion of the exchange offer and ending on the earlier of the date 180 days after the date of completion of the exchange offer or such time as all broker-dealers no longer own any old notes.

Under the circumstances described below, we also agreed to use our commercially reasonable efforts to cause the SEC to declare effective a shelf registration statement with respect to the resale of the old notes. We agreed to keep the shelf registration statement effective until the earlier of the date two years after the shelf registration statement is declared effective under the Securities Act or the date on which there are no longer any old notes outstanding. These circumstances include:

•: if any change in law or applicable interpretations of those laws by the SEC do not permit us to effect the exchange offer as contemplated by the registration rights agreement;
•: if the exchange offer is not consummated within 180 days following the sale of the old notes on March 24, 2011; or
•: if any holder of the old notes is not eligible to participate in the exchange offer and notifies us in writing within 30 days following consummation of the exchange offer that it is prohibited by law or SEC policy from participating in the exchange offer, that the registration statement of which this prospectus is a part is not appropriate or available for the resale of the new notes acquired by it in the exchange offer and that the delivery of a prospectus is required, or that it is a broker-dealer and owns notes acquired directly from us or an affiliate of ours.

If we fail to comply with specified obligations under the registration rights agreement, we must pay certain additional interest to the holders of the notes until we have cured all of such failures.

By participating in the exchange offer, holders of the old notes will receive new notes that are freely tradeable and not subject to restrictions on transfer, subject to the exceptions described below under "Resale of New Notes."

Resale of New Notes

We believe that the new notes issued in exchange for the old notes may be offered for resale, resold and otherwise transferred by any new note holder without compliance with the registration and prospectus delivery provisions of the Securities Act if the conditions set forth below are met. We base

Table of Contents

this belief solely on interpretations of the federal securities laws by the SEC set forth in several no-action letters issued to third parties unrelated to us. A no-action letter is a letter from the SEC responding to a request for its views as to whether a particular matter complies with the federal securities laws or whether the SEC would refer the matter to the SEC's enforcement division for action. The relevant no-action letters include the Exxon Capital Holdings Corporation letter, which was made available by the SEC on May 13, 1988, the Morgan Stanley & Co. Incorporated letter which was made available by the SEC on June 5, 1991, the K-111 Communications Corporation letter, which was made available by the SEC on May 14, 1993, and the Shearman & Sterling letter, which was made available by the SEC on July 2, 1993. We have not obtained, and do not intend to obtain, our own no-action letter from the SEC regarding the resale of the new notes. Instead, holders will be relying on the no-action letters that the SEC has issued to third parties in circumstances that we believe are similar to ours. Based on these no-action letters, the following conditions must be met:

•: the holder must acquire the new notes in the ordinary course of its business for investment purposes;
•: the holder must have no arrangements or understanding with any person to participate in the distribution of the new notes within the meaning of the Securities Act; and
•: the holder must not be an "affiliate," as defined in Rule 405 under the Securities Act, of ours.

Each holder of old notes that wishes to exchange old notes for new notes in the exchange offer must represent to us that it satisfies all of the above listed conditions. Any holder who tenders in the exchange offer who does not satisfy all of the above listed conditions:

•: cannot rely on the position of the SEC set forth in the no-action letters referred to above; and
•: must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes.

The SEC considers broker-dealers that acquired old notes directly from us, but not as a result of market-making activities or other trading activities, to be making a distribution of the new notes if they participate in the exchange offer. Consequently, any such holders must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes.

Each broker-dealer that receives new notes for its own account in exchange for old notes acquired by such broker-dealer as a result of market-making activities or other trading activities must deliver a prospectus in connection with a resale of the new notes and provide us in the letter of transmittal with a signed acknowledgement of this obligation. The letter of transmittal states that by so acknowledging and delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. A broker-dealer may use this prospectus, as amended or supplemented from time to time, in connection with resales of new notes received in exchange for old notes where the broker-dealer acquired the old notes as a result of market-making activities or other trading activities. We have agreed that for a period of 180 days after the expiration date of the exchange offer, we will make this prospectus available to broker-dealers for use in connection with any such resale of the new notes. See "Plan of Distribution."

Except as described in the prior paragraph, holders may not use this prospectus for an offer to resell, resale or other retransfer of new notes. We are not making the exchange offer to, nor will we accept tenders for exchange from, holders of old notes in any jurisdiction in which the exchange offer or the acceptance of it would not be in compliance with the securities or blue sky laws of that jurisdiction.

Table of Contents

Terms of the Exchange

Upon the terms and subject to the conditions set forth in this prospectus and the accompanying letter of transmittal, which we refer to together in this prospectus as the "exchange offer," we will accept any and all old notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the expiration date described below under "Expiration Date; Extensions; Amendments." The date of acceptance for exchange of the old notes, and completion of the exchange offer, is the exchange date, which will be the first business day following the expiration date, unless extended as described in this prospectus. We will issue, on or promptly after the exchange date, an aggregate principal amount of up to $250.0 million of new notes for a like principal amount of outstanding old notes tendered and accepted in connection with the exchange offer. The new notes issued in connection with the exchange offer will be delivered promptly following the exchange date. Holders may tender some or all of their old notes in connection with the exchange offer, but only in integral multiples of $1,000. The exchange offer is not conditioned upon any minimum amount of old notes being tendered for exchange.

The terms of the new notes are identical in all material respects to the terms of the old notes, except that:

•: we have registered the new notes under the Securities Act and therefore the new notes will not bear legends restricting their transfer;
•: the new notes will have a different CUSIP number than the old notes (with the CUSIP number for the new notes being the same as that of the $270.0 million of original 2016 notes which are also now outstanding under the indenture); and
•: specified rights under the exchange and registration rights agreement, including the provisions providing for payment of additional interest in specified circumstances relating to the exchange offer, will be limited or eliminated.

The new notes will be newly issued securities for which there is currently no market, and we do not intend to list the new notes on any securities exchange. Although the initial purchasers of the old notes have informed us that they intend to make a market in the new notes, they are not obligated to do so and may discontinue market-making at any time without notice. Accordingly, a liquid market for the new notes may not develop or be maintained.

The new notes will evidence the same debt as the old notes. The new notes will be issued under the same indenture and entitled to the same benefits under that indenture as the old notes being exchanged. As of the date of this prospectus, $250.0 million in aggregate principal amount of the old notes were outstanding. Old notes accepted for exchange will be retired and cancelled and not reissued.

In connection with the issuance of the old notes, we arranged for the old notes originally purchased by qualified institutional buyers and those sold in reliance on Regulation S under the Securities Act to be issued and transferable in book-entry form through the facilities of The Depository Trust Company, or "DTC," acting as depositary. We will issue the new notes in the form of a global note registered in the name of DTC or its nominee and each beneficial owner's interest in such global note will be transferable in book-entry form through DTC.

Holders of old notes do not have any appraisal or dissenters' rights in connection with the exchange offer. We intend to conduct the exchange offer in accordance with the applicable requirements of the Exchange Act and the rules and regulations of the SEC.

We shall be considered to have accepted validly tendered old notes if and when we have given written notice to that effect to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the new notes from us.

Table of Contents

If we do not accept any tendered old notes for exchange because of an invalid tender, the occurrence of the other events described in this prospectus or otherwise, we will return these old notes, without expense, to the tendering holder promptly after the expiration date of the exchange offer.

Holders who tender old notes will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes on exchange of old notes in connection with the exchange offer. We will pay all charges and expenses, other than the applicable taxes described in the section "Fees and Expenses" below, in connection with the exchange offer.

If we successfully complete the exchange offer, any old notes which holders do not tender or which we do not accept in the exchange offer will remain outstanding and continue to accrue interest. The holders of old notes after the exchange offer in general will not have further rights under the registration rights agreement, including registration rights and any rights to additional interest. Holders of the old notes wishing to transfer their old notes would have to rely on exemptions from the registration requirements of the Securities Act.

Expiration Date; Extensions; Amendments

The expiration date for the exchange offer is 5:00 p.m., New York City time, on , 2011. We may extend this expiration date in our sole discretion, but in no event to a date later than , 2011. If we so extend the expiration date, the term "expiration date" shall mean the latest date and time to which we extend the exchange offer.

We reserve the right, in our sole discretion:

•: to delay accepting any old notes to the extent we extend the exchange offer;
•: to extend the exchange offer;
•: to terminate the exchange offer if, in our reasonable judgment, any of the conditions described below shall not have been satisfied; or
•: to amend the terms of the exchange offer in any manner, provided, however, that if we make a material change in the exchange offer (including a waiver of a material condition), we will extend the offering period if necessary so that at least five business days remain in the offering period following notice of the material change.

We will give oral or written notice of any delay, extension or termination to the exchange agent. In addition, we will promptly give oral or written notice regarding any delay in acceptance, extension or termination of the offer to the registered holders of old notes. If we amend the exchange offer in a manner that we determine to constitute a material change, or if we waive a material condition, we will promptly disclose the amendment or waiver in a manner reasonably calculated to inform the holders of old notes of the amendment, and extend the offer if required by law.

Without limiting the manner in which we may choose to make public announcements of any delay in acceptance, extension, termination, amendment or waiver regarding the exchange offer, we shall have no obligation to publish, advertise, or otherwise communicate any public announcement, other than by making a release to a financial news service not later than 9:00 a.m., Eastern time on the business day after the previously scheduled expiration date.

Interest on the New Notes

Interest on the new notes will accrue at the rate of 7⁵/8% per annum on the principal amount, payable semiannually in arrears on February 15 and August 15, commencing on August 15, 2011. In order to avoid duplicative payment of interest, all interest accrued on old notes that are accepted for

Table of Contents

exchange before February 15, 2012 will be superseded by the interest that is deemed to have accrued on the new notes from August 14, 2011 through the date of the exchange.

Conditions to the Exchange Offer

Despite any other term of the exchange offer, we will not be required to accept for exchange, or exchange new notes for, any old notes and we may terminate the exchange offer as provided in this prospectus before the exchange offer's termination if:

•: the exchange offer, or the making of any exchange by a holder, violates, in our good faith determination, any applicable law, rule or regulation or any applicable interpretation of the staff of the SEC;
•: any action or proceeding shall have been instituted with respect to the exchange offer which, in our judgment, would impair our ability to proceed with the exchange offer; or
•: we have not obtained any governmental approval which we, in our good faith determination, consider necessary for the completion of the exchange offer as contemplated by this prospectus.

The conditions listed above are for our sole benefit and we may assert them regardless of the circumstances giving rise to any of these conditions. We may waive these conditions in our sole discretion in whole or in part at any time. A failure on our part to exercise any of the above rights shall not constitute a waiver of that right, and that right shall be considered an ongoing right, which we may assert at any time and from time to time. However, all conditions other than those dependent upon receipt of any required governmental approval must be satisfied or waived prior to the expiration of the exchange offer (as extended, if applicable), in order for us to complete the exchange offer. Furthermore, if we elect to waive any condition, we must announce that decision in a manner reasonably calculated to inform noteholders of the waiver.

If we determine in our reasonable discretion that any of the events listed above has occurred, we may, subject to applicable law:

•: refuse to accept any old notes and return all tendered old notes to the tendering holders;
•: extend the exchange offer and retain all old notes tendered before the expiration of the exchange offer, subject, however, to the rights of holders to withdraw these old notes; or
•: waive unsatisfied conditions relating to the exchange offer and accept all properly tendered old notes which have not been withdrawn.

Any determination by us concerning the above events will be final and binding.

In addition, we reserve the right in our reasonable discretion to:

•: purchase or make offers for any old notes that remain outstanding subsequent to the expiration date; and
•: to the extent permitted by applicable law, purchase old notes in the open market, in privately negotiated transactions or otherwise.

The terms of any such purchases or offers may differ from the terms of the exchange offer.

Procedures for Tendering

Except in limited circumstances, only a DTC participant listed on a DTC securities position listing with respect to the old notes may tender old notes in the exchange offer. To tender old notes in the exchange offer, holders of old notes that are DTC participants may follow the procedures for book-entry transfer as set forth below under "Book-Entry Transfer" and in the letter of transmittal.

Table of Contents

In addition, you must comply with one of the following:

•: the exchange agent must receive, before expiration of the exchange offer, a timely confirmation of book-entry transfer of old notes into the exchange agent's account at DTC according to DTC's standard operating procedures for electronic tenders and a properly transmitted agent's message as described below; or
•: the exchange agent must receive any corresponding certificate or certificates representing old notes along with the letter of transmittal; or
•: the holder must comply with the guaranteed delivery procedures described below.

The tender by a holder of old notes will constitute an agreement between such holder and us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal. If less than all the old notes held by a holder are tendered, the tendering holder should fill in the amount of old notes being tendered in the specified box on the letter of transmittal. The entire amount of old notes delivered or transferred to the exchange agent will be deemed to have been tendered unless otherwise indicated.

The method of delivery of old notes, the letter of transmittal and all other required documents or transmission of an agent's message, as described under "Book-Entry Transfer," to the exchange agent is at the election and risk of the holder. Instead of delivery by mail, we recommend that holders use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure timely delivery to the exchange agent prior to the expiration of the exchange offer. No letter of transmittal or old notes should be sent to us or DTC. Delivery of documents to DTC in accordance with its procedures will not constitute delivery to the exchange agent.

Any beneficial holder whose old notes are registered in the name of his or its broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact such registered holder promptly and instruct such registered holder to tender on its behalf. If such beneficial holder wishes to tender on its own behalf, such beneficial holder must, prior to completing and executing the letter of transmittal and delivering its old notes, either:

•: make appropriate arrangements to register ownership of the old notes in such holder's name; or
•: obtain a properly completed bond power from the registered holder.

The transfer of record ownership may take considerable time and may not be completed prior to the expiration date.

Signatures on a letter of transmittal or a notice of withdrawal, as described in "—Withdrawal of Tenders" below, must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc., a commercial bank or trust company having an office or correspondent in the United States or an "eligible guarantor institution," within the meaning of Rule 17Ad-15 under the Exchange Act, which we refer to in this prospectus as an "eligible institution," unless the old notes are tendered:

•: by a registered holder who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the letter of transmittal; or
•: for the account of an eligible institution.

If the letter of transmittal is signed by a person other than the registered holder of any old notes listed therein, the old notes must be endorsed or accompanied by appropriate bond powers which authorize the person to tender the old notes on behalf of the registered holder, in either case signed as the name of the registered holder or holders appears on the old notes. If the letter of transmittal or any old notes or bond powers are signed by trustees, executors, administrators, guardians,

Table of Contents

attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing and, unless waived by us, evidence satisfactory to us of their authority to so act must be submitted with the letter of transmittal.

We will determine in our sole discretion all questions as to the validity, form, eligibility, including time of receipt, and acceptance and withdrawal of tendered old notes. We reserve the absolute right to reject any and all old notes not properly tendered or any old notes whose acceptance by us would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to any particular old notes either before or after the expiration date. However, all conditions other than those dependent upon receipt of any required governmental approval, must be satisfied or waived prior to the expiration of the exchange offer (as extended, if applicable) in order for us to complete the exchange offer. Furthermore, if we elect to waive any condition, we must announce that decision in a manner reasonably calculated to inform noteholders of the waiver. 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, holders must cure any defects or irregularities in connection with tenders of old notes within a period we will determine. Although we intend to request the exchange agent to notify holders of defects or irregularities relating to tenders of old notes, neither we, the exchange agent nor any other person will have any duty or incur any liability for failure to give this notification. We will not consider tenders of old notes to have been made until these defects or irregularities have been cured or waived. The exchange agent will return any old notes that are not properly tendered and as to which the defects or irregularities have not been cured or waived to the tendering holders, unless otherwise provided in the letter of transmittal, promptly following the expiration date.

In addition, we reserve the right, as set forth above under the caption "Conditions to the Exchange Offer," to terminate the exchange offer.

By tendering, each holder represents to us, among other things, that:

•: the holder acquired new notes pursuant to the exchange offer in the ordinary course of its business;
•: the holder has no arrangement or understanding with any person to participate in the distribution of the new notes within the meaning of the Securities Act; and
•: the holder is not our "affiliate," as defined in Rule 405 under the Securities Act.

If the holder is a broker-dealer which will receive new notes for its own account in exchange for old notes acquired by such broker-dealer as a result of market-making activities or other trading activities, such holder must acknowledge that it will deliver a prospectus in connection with any resale of the new notes.

Book-Entry Transfer

We understand that the exchange agent will make a request promptly after the date of this prospectus to establish an account with respect to the old notes at DTC for the purpose of facilitating the exchange offer. Any financial institution that is a participant in DTC's system, including Euroclear and Clearsteam, may make book-entry delivery of old notes by causing DTC to transfer such old notes into the exchange agent's DTC account in accordance with DTC's Automated Tender Offer Program procedures for such transfer. The exchange of new notes for tendered old notes will only be made after a timely confirmation of a book-entry transfer of the old notes into the exchange agent's account and timely receipt by the exchange agent of an agent's message.

The term "agent's message" means a message, transmitted by DTC and received by the exchange agent and forming part of the confirmation of a book-entry transfer, which states that DTC has

Table of Contents

received an express acknowledgment from a participant tendering old notes that such participant has received an appropriate letter of transmittal and agrees to be bound by the terms of the letter of transmittal, and that we may enforce such agreement against the participant. Delivery of an agent's message will also constitute an acknowledgment from the tendering DTC participant that the representations contained in the letter of transmittal and described under "Resale of New Notes" above are true and correct.

Guaranteed Delivery Procedures

The following guaranteed delivery procedures are intended for holders who wish to tender their old notes but:

•: their old notes are not immediately available;
•: the holders cannot deliver their old notes, the letter of transmittal, or any other required documents to the exchange agent prior to the expiration date; or
•: the holders cannot complete the procedure under DTC's standard operating procedures for electronic tenders before expiration of the exchange offer.

The conditions that must be met to tender old notes through the guaranteed delivery procedures are as follows:

•

the tender must be made through an eligible institution;

•

before expiration of the exchange offer, the exchange agent must receive from the eligible institution either a properly completed and duly executed notice of guaranteed delivery in the form accompanying this prospectus, by facsimile transmission, mail or hand delivery, or a properly transmitted agent's message in lieu of notice of guaranteed delivery:

•: setting forth the name and address of the holder, the certificate number or numbers of the old notes tendered and the principal amount of old notes tendered;
•: stating that the tender offer is being made by guaranteed delivery;
•: guaranteeing that, within three business days after expiration of the exchange offer, the letter of transmittal, or facsimile of the letter of transmittal, together with the old notes tendered or a book-entry confirmation, and any other documents required by the letter of transmittal will be deposited by the eligible institution with the exchange agent; and

•

the exchange agent must receive the properly completed and executed letter of transmittal, or facsimile of the letter of transmittal, as well as all tendered old notes in proper form for transfer or a book-entry confirmation, and any other documents required by the letter of transmittal, within three New York Stock Exchange trading days after expiration of the exchange offer.

Upon request to the exchange agent, a notice of guaranteed delivery will be sent to holders who wish to tender their old notes according to the guaranteed delivery procedures set forth above.

Withdrawal of Tenders

Your tender of old notes pursuant to the exchange offer is irrevocable except as otherwise provided in this section. You may withdraw tenders of old notes at any time prior to 5:00 p.m., New York City time, on the expiration date.

For a withdrawal to be effective:

•: the exchange agent must receive a written notice, which may be by telegram, telex, facsimile transmission or letter, of withdrawal at the address set forth below under "Exchange Agent," or

Table of Contents

•: for DTC participants, holders must comply with DTC's standard operating procedures for electronic tenders and the exchange agent must receive an electronic notice of withdrawal from DTC.

Any notice of withdrawal must:

•: specify the name of the person who tendered the old notes to be withdrawn;
•: identify the old notes to be withdrawn, including the certificate number or numbers and principal amount of the old notes to be withdrawn;
•: be signed by the person who tendered the old notes in the same manner as the original signature on the letter of transmittal, including any required signature guarantees; and
•: specify the name in which the old notes are to be re-registered, if different from that of the withdrawing holder.

If old notes have been tendered pursuant to the procedure for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn old notes and otherwise comply with the procedures of the applicable facility. We will determine in our sole discretion all questions as to the validity, form and eligibility, including time of receipt, for such withdrawal notices, and our determination shall be final and binding on all parties. Any old notes so withdrawn will be deemed not to have been validly tendered for purposes of the exchange offer and no new notes will be issued with respect to them unless the old notes so withdrawn are validly re-tendered. Any old notes which have been tendered but which are not accepted for exchange will be returned to the holder without cost to such holder promptly after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn old notes may be re-tendered by following the procedures described above under "Procedures for Tendering" at any time prior to the expiration date.

Exchange Agent

We have appointed U.S. Bank National Association as exchange agent in connection with the exchange offer. Holders should direct questions, requests for assistance and for additional copies of this prospectus, the letter of transmittal or notices of guaranteed delivery to the exchange agent addressed as follows:


By Hand or Overnight Courier:		By Facsimile Transmission:
U.S. Bank National Association		(651) 495-8158
60 Livingston Avenue, 1^st Floor Bond Drop Window		(For Eligible Institutions Only)
St. Paul, Minnesota 55107		U.S. Bank National Association
Attention: Specialized Finance		Attention: Specialized Finance
(800) 934-6802		Confirm by Telephone:
		(800) 934-6802

Delivery of a letter of transmittal to any address or facsimile number other than the one set forth above will not constitute a valid delivery.

Fees and Expenses

We will not make any payments to brokers, dealers or other persons soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and will pay the exchange agent for its related reasonable out-of-pocket expenses, including accounting and legal fees. We may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this prospectus, letters of

Table of Contents

transmittal and related documents to the beneficial owners of the old notes and in handling or forwarding tenders for exchange.

Holders who tender their old notes for exchange will not be obligated to pay any transfer taxes. If, however:

•: new notes are to be delivered to, or issued in the name of, any person other than the registered holder of the old notes tendered; or
•: tendered old notes are registered in the name of any person other than the person signing the letter of transmittal; or
•: a transfer tax is imposed for any reason other than the exchange of old notes in connection with the exchange offer;

then the tendering holder must pay the amount of any transfer taxes due, whether imposed on the registered holder or any other persons. If the tendering holder does not submit satisfactory evidence of payment of these taxes or exemption from them with the letter of transmittal, the amount of these transfer taxes will be billed directly to the tendering holder.

Consequences of Failure to Properly Tender Old Notes in the Exchange

We will issue the new notes in exchange for old notes under the exchange offer only after timely receipt by the exchange agent of the old notes, a properly completed and duly executed letter of transmittal and all other required documents. Therefore, holders of the old notes desiring to tender old notes in exchange for new notes should allow sufficient time to ensure timely delivery. We are under no duty to give notification of defects or irregularities of tenders of old notes for exchange. Old notes that are not tendered or that are tendered but not accepted by us will, following completion of the exchange offer, continue to be subject to the existing restrictions upon transfer under the Securities Act. Upon completion of the exchange offer, specified rights under the exchange and registration rights agreement, including registration rights and any right to additional interest, will be either limited or eliminated.

Participation in the exchange offer is voluntary. In the event the exchange offer is completed, we will not be required to register the remaining old notes. Remaining old notes will continue to be subject to the following restrictions on transfer:

•: holders may resell old notes only if we register the old notes under the Securities Act, if an exemption from registration is available, or if the transaction requires neither registration under nor an exemption from the requirements of the Securities Act; and
•: the remaining old notes will bear a legend restricting transfer in the absence of registration or an exemption.

We do not currently anticipate that we will register the remaining old notes under the Securities Act. To the extent that old notes are tendered and accepted in connection with the exchange offer, any trading market for remaining old notes could be adversely affected.

DESCRIPTION OF THE NOTES

You can find the definitions of certain terms used in this "Description of the Notes" below under the subheading "—Certain Definitions." In this description, the term "Issuer" refers to Clean Harbors, Inc. and not any of its Subsidiaries. The Issuer previously issued $300.0 million aggregate principal amount of its 7⁵/8% Senior Secured Notes due 2016 (the "original 2016 notes") under an indenture dated as of August 14, 2009 (the "indenture") among itself, the Guarantors and U.S. Bank National Association, as trustee and notes collateral agent. The Issuer redeemed $30.0 million of the original 2016 notes on September 28, 2010, leaving $270.0 million of the original 2016 notes now outstanding. The Issuer also issued $150.0 million aggregate principal amount of 7⁵/8% Senior Secured Notes due 2016 (the "old notes") on March 24, 2011 under the indenture in an unregistered private placement, and will issue up to $250.0 million aggregate principal amount of 7⁵/8% Senior Secured Notes due 2016 (the "new notes") in exchange for the old notes under the indenture pursuant to this registered exchange offer. The original 2016 notes and the old notes constitute, and the new notes will constitute, "Securities" under the indenture. References to "notes" herein shall include the original 2016 notes, the old notes and the new notes, collectively.

The terms of the new notes are substantially identical to the terms of the old notes for which they may be exchanged pursuant to the exchange offer, except that the new notes are registered under the Securities Act and do not contain provisions requiring the payment of additional interest in connection with the failure to comply with the registration covenants in the registration rights agreement. The new notes will bepari passu with, and vote together with, the holders of the original 2016 notes and any old notes which are not exchanged for new notes on any matter submitted to the holders of notes under the indenture.

The following description is a summary of the material provisions of the indenture and certain provisions of the Security Documents. It does not restate the terms of those agreements in their entirety. We urge that you carefully read the indenture, the Security Documents and the Trust Indenture Act of 1939 (the "TIA"), because the indenture, the Security Documents and the TIA govern your rights as holders of the notes, not this description. A copy of the indenture and forms of the Security Documents may be obtained from us or the initial purchasers. The definitions of certain capitalized terms used in the following summary are set forth below under "—Certain Definitions." In this description, "we," "us" or "our" refers only to the Issuer and not any of its Subsidiaries.

General

The notes are:

•: general senior obligations of the Issuer;
•: subject to the Lien priorities described below,pari passu in right of payment with any existing and future senior Indebtedness of the Issuer;
•: secured on a first-priority lien basis by the Notes Collateral and on a second-priority lien basis by the ABL Collateral, in each case, subject to certain Liens permitted under the indenture;
•: senior in right of payment to any existing or future subordinated debt of the Issuer;
•: effectively senior to the Issuer's obligations to the ABL Secured Parties to the extent of the value of the Notes Collateral;
•: structurally subordinated to all liabilities and preferred stock of Subsidiaries of the Issuer that are not Guarantors;
•: effectively subordinated to the Issuer's obligations to the ABL Secured Parties to the extent of the value of the ABL Collateral; and

Table of Contents

•: guaranteed on a senior secured basis (with the Lien priorities described below) by each Guarantor.

As of March 31, 2011, we and the Guarantors had no loans and $82.4 million of letters of credit outstanding under the Credit Agreement. The notes and the guarantees rank effectively junior in right of payment to Indebtedness (including loans and reimbursement obligations in respect of outstanding letters of credit) under the Credit Agreement to the extent of the value of the ABL Collateral. Furthermore, our non-guarantor Subsidiaries had as of March 31, 2011, approximately $134.6 million of total liabilities (excluding intercompany liabilities and debt). The notes and the guarantees rank structurally junior to those obligations of our non-guarantor Subsidiaries.

The notes are issued in fully registered form only, without coupons, in denominations of $2,000 and integral multiples of $1,000.

The trustee serves as paying agent and registrar for the notes. You may present your notes for registration of transfer and exchange at the offices of the registrar, which is the trustee's corporate trust office. The Issuer may change any paying agent and registrar without prior notice.

The Issuer pays principal (and premium, if any) on the notes at the trustee's corporate office in St. Paul, Minnesota. At the Issuer's option, interest may be paid at the trustee's corporate trust office or by check mailed to the registered address of holders.

Principal, Maturity and Interest

The Issuer will issue an aggregate principal amount of up to $250.0 million of new notes in this offering. The notes will mature on August 15, 2016. Additional notes ("Additional Notes") may be issued under the indenture from time to time after the Issue Date (and the new notes shall be Additional Notes), subject to the limitations set forth under "—Certain Covenants—Limitation on Incurrence of Additional Indebtedness" and "—Certain Covenants—Limitation on Liens." The notes, the new notes, any old notes which are not exchanged pursuant to this exchange offer and any Additional Notes subsequently issued will be treated as a single class for all purposes under the indenture.

Interest on the notes is payable semiannually in cash on each February 15 and August 15 to the persons who are registered holders at the close of business on the February 1 and August 1 immediately preceding the applicable interest payment date. Interest on the new notes will accrue from August 14, 2011 and will be computed on the basis of a 360-day year of twelve 30-day months. The first interest payment date for the new notes will be February 15, 2012. In order to avoid duplicative payment of interest, all interest accrued on old notes that are accepted for exchange before February 15, 2012 will be superseded by the interest that is deemed to have accrued on the new notes from August 14, 2011 through the date of the exchange.

The notes will not be entitled to the benefit of any mandatory sinking fund.

Redemption

Optional Redemption

The Issuer may redeem all or any portion of the notes, on and after August 15, 2012, upon not less than 30 nor more than 60 days' notice, at the following redemption prices (expressed as percentages of the principal amount) if redeemed during the twelve-month period commencing on

Table of Contents

August 15 of the year set forth below, plus, in each case, accrued and unpaid interest, if any, to the date of redemption:

Year

2012	103.813	%
2013	101.906	%
2014 and thereafter	100.000	%

At any time prior to August 15, 2012, the Issuer may, on one or more occasions, redeem all or any portion of the notes, upon not less than 30 nor more than 60 days' notice, at a redemption price equal to 100% of the principal amount of the notes redeemed, plus the Applicable Premium as of the date of redemption, including accrued and unpaid interest to the redemption date.

In addition, at any one time after September 29, 2011 but prior to August 15, 2012, the Issuer may redeem up to 10% of the original aggregate principal amount of notes issued under the indenture at a redemption price of 103% of the principal amount thereof, plus accrued and unpaid interest to the applicable redemption date.

Optional Redemption upon Equity Offerings

At any time, or from time to time, prior to August 15, 2012, the Issuer may, at its option, use the net cash proceeds of one or more Equity Offerings to redeem up to 35% in aggregate principal amount of the notes originally issued under the indenture at a redemption price equal to 107.625% of the principal amount thereof plus accrued and unpaid interest thereon, if any, to the date of redemption;provided,however, that after any such redemption the aggregate principal amount of the notes outstanding must equal at least 65% of the aggregate amount of the notes originally issued under the indenture. In order to effect the foregoing redemption with the net cash proceeds of any Equity Offering, the Issuer shall make such redemption not more than 90 days after the consummation of such Equity Offering.

Selection and Notice of Redemption

If less than all of the notes are to be redeemed at any time, the trustee will select those notes for redemption in compliance with the requirements of the principal national securities exchange, if any, on which the notes are listed or, if the notes are not then listed on a national securities exchange, on apro rata basis,provided that:

(1): notes with a principal amount of $2,000 or less may only be redeemed in full; and
(2): if a partial redemption is made with the Net Cash Proceeds of an Asset Sale, an Equity Offering, or any Taking or Destruction, the trustee will select the notes or portions of the notes for redemption on a pro rata basis or on as nearly apro rata basis as is practicable, unless the method is otherwise prohibited.

Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount to be redeemed. A replacement note in a principal amount equal to the unredeemed portion will be issued in the name of the holder upon cancellation of the original note. On and after the redemption date, interest will cease to accrue on those notes called for redemption if the Issuer has deposited with the paying agent the funds needed to pay the applicable redemption price.

Table of Contents

Guarantees

Each Guarantor fully and unconditionally guarantees, on a senior secured basis, jointly and severally, to each holder of notes and the trustee, the full and prompt performance of the Issuer's obligations under the indenture and the notes, including the payment of principal of and interest on the notes. Each Guarantee is:

•: a senior obligation of such Guarantor;
•: subject to the Lien priorities described below,pari passu in right of payment with any existing and future senior Indebtedness of such Guarantor;
•: secured on a first-priority basis by the Notes Collateral owned by such Guarantor and on a second-priority basis by the ABL Collateral owned by such Guarantor; in each case, subject to certain Liens permitted under the indenture;
•: senior in right of payment to any existing or future subordinated debt of such Guarantor;
•: effectively senior to such Guarantor's obligations to the ABL Secured Parties to the extent of the value of the Notes Collateral owned by such Guarantor;
•: structurally subordinated to all liabilities and preferred stock of any Subsidiaries of such Guarantor that are not Guarantors; and
•: effectively subordinated to such Guarantor's obligations to the ABL Secured Parties to the extent of the value of the ABL Collateral owned by such Guarantor.

The obligations of each Guarantor are limited to the maximum amount which, 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 the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. Each Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a contribution from each other Guarantor in an amountpro rata, based on the net assets of each Guarantor, determined in accordance with GAAP.

Each Guarantor may consolidate with or merge into or sell its assets to the Issuer or another Guarantor without limitation, or with other Persons upon the terms and conditions set forth in the indenture. See "—Certain Covenants—Merger, Consolidation and Sale of Assets." In the event all of the Capital Stock of a Guarantor is disposed of by the Issuer, whether by merger, consolidation, sale or otherwise, and the disposition is not in violation of the provisions set forth in "—Certain Covenants—Limitation on Asset Sales," the Guarantor's Guarantee will be released. In addition, upon the designation of a Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary, which designation is in compliance with the indenture, such Guarantor's Guarantee will be released.

Security

The notes and the Guarantees have the benefit of the "Collateral," which consists of (i) the Notes Collateral, as to which the holders of the notes and holders of any future Other Pari Passu Lien Obligations have a first-priority security interest and the Bank Lenders have a second-priority security interest (in each case subject to Permitted Liens) and (ii) the ABL Collateral, as to which the Bank Lenders have a first-priority security interest, the holders of the notes have a second-priority security interest and holders of any future Other Pari Passu Lien Obligations may have a second-priority security interest (in each case, subject to Permitted Liens).

Table of Contents

The Issuer and the Guarantors are able to incur additional Indebtedness in the future which could share in all or part of the Collateral. The amount of all such additional Indebtedness is limited by the covenants described under "—Certain Covenants—Limitation on Liens" and "—Certain Covenants—Limitation on Incurrence of Additional Indebtedness." Under certain circumstances the amount of such additional secured Indebtedness could be significant.

Notes Collateral

The Notes Collateral is pledged as collateral to the Notes Collateral Agent for the benefit of the trustee, the Notes Collateral Agent, the holders of the notes and any holders of Other Pari Passu Lien Obligations. The notes and Guarantees are secured by first-priority security interests in the Notes Collateral, subject to certain Permitted Liens. The "Notes Collateral" generally consists of the following assets of the Issuer and the Guarantors:

•: each real property owned by the Issuer and the Guarantors with a cost or book value (whichever is greater) in excess of $2.5 million, and leasehold real properties acquired after the Issue Date with annual rents in excess of $2.5 million, together with all fixtures relating thereto and all other improvements thereto and all leases, rents and other income derived therefrom or relating thereto;provided that, in the case of leaseholds only (but not with respect to owned real property), the Issuer and the Guarantors shall only be required to use commercially reasonable efforts to obtain leasehold mortgages or other security interests with respect thereto and shall in no event be required to obtain such leasehold mortgages or other security interests if prohibited by applicable law, regulation or contract;
•: equipment;
•: motor vehicles (but any actions to perfect the lien thereon shall only apply to those motor vehicles with a fair market value in excess of $50,000);
•: inventory;
•: patents, trademarks and copyrights;
•: general intangibles, instruments, books and records and supporting obligations related to the foregoing and proceeds of the foregoing;
•: deposit accounts and securities accounts, to the extent containing identifiable proceeds of Notes Collateral (with certain exceptions for special purpose and de minimis accounts); and
•: substantially all of the other tangible and intangible assets of the Issuer and the Guarantors, other than (i) the ABL Collateral and (ii) Excluded Collateral.

Initially, subject to Permitted Liens, only the notes and Guarantees will have the benefit of the first-priority security interest in the Notes Collateral. In the future, holders of Other Pari Passu Lien Obligations (if any) will also have the benefit of a first-priority security interest in the Notes Collateral.

ABL Collateral

The notes and Guarantees are also secured by a second-priority Lien on and security interest in the ABL Collateral, subject to Permitted Liens. The "ABL Collateral" generally consists of all of the following assets of the Issuer and the Guarantors:

•: all accounts receivable;
•: all deposit accounts and securities accounts (and all assets and amounts contained therein but excluding (i) identifiable proceeds of the Notes Collateral and (ii) certain special purpose andde minimis deposit accounts); and

Table of Contents

•: all general intangibles, instruments, books and records and supporting obligations related to the foregoing and proceeds of the foregoing, in each case, held by the Issuer and the Guarantors.

The notes' second-priority Lien on and security interest in the ABL Collateral will be terminated and automatically released if the Lien on such ABL Collateral in favor of the ABL Secured Parties is released in connection with any sale or other disposition of such ABL Collateral in connection with an enforcement action by the Bank Collateral Agent or in connection with a sale of such ABL Collateral permitted by the Credit Agreement (whether or not such sale is permitted under the indenture), except in connection with a Discharge of ABL Obligations. Except as provided in the Intercreditor Agreement, holders of Liens on the ABL Collateral that are junior relative to the Bank Lenders will not be able to take any enforcement action with respect to the ABL Collateral so long as any ABL Obligations are outstanding.

Excluded Property

The Collateral does not include (A) assets of the Issuer and the Guarantors held outside of the United States; (B) assets of the Issuer's foreign Subsidiaries; (C) any capital stock, debt securities, instruments, other equity interests and other securities of any Subsidiary of the Issuer (other than any securities accounts);provided that (x) notwithstanding the foregoing, intercompany Indebtedness held by the Issuer or any Guarantor is deemed Collateral, but no securities evidencing the same are required to be delivered to the Notes Collateral Agent and any such securities (but not the Indebtedness underlying such securities) are not Collateral, (y) neither the Issuer nor any Guarantor or any of its Restricted Subsidiaries has or shall pledge or grant any security interest in any such security to any Person without the consent of the Notes Collateral Agent and (z) the intercompany loans (or any whole or partial replacements or refinancings thereof) made on July 31, 2009 and on or about the Issue Date to one or more Canadian Subsidiaries of the Issuer are not evidenced by a note or a security; and (D) proceeds and products from any and all of the foregoing excluded collateral described in clauses (A) through (C) above (collectively, the "Excluded Collateral").

No appraisals of any of the Collateral have been prepared by or on behalf of the Issuer in connection with the issuance and sale of the notes. In addition, the Issuer and the Guarantors do not know and have not attempted to determine the value of the Excluded Collateral. There can be no assurance that the proceeds from the sale of the Collateral in whole or in part pursuant to the Security Documents following an Event of Default would be sufficient to satisfy payments due on the notes. By its nature, some or all of the Collateral will be illiquid and may have no readily ascertainable market value. Accordingly, there can be no assurance that the Collateral can be sold in a short period of time, or at all.

The collateral release provisions of the indenture and the Security Documents permit the release of Collateral without substitution of collateral of equal value under certain circumstances. See "—Release of Collateral."

The Issuer and the Guarantors will use their commercially reasonable efforts to complete within 30 days after the issuance of the new notes all filings and other similar actions required in connection with the perfection of security interests in real property. If they are not able to complete such actions on or prior to such date, they will complete such actions as soon as reasonably practicable after such date.

To the extent that third parties hold Liens permitted by the Security Documents and the indenture, such third parties will have rights and remedies with respect to the assets subject to such Liens that, if exercised, could adversely affect the value of the Collateral or the ability of the trustee or the holders of notes to realize or foreclose on the Collateral. In addition, the ability of the holders of notes to realize on the Collateral may be subject to certain bankruptcy law limitations in the event of a bankruptcy. See "—Certain Bankruptcy Limitations."

Table of Contents

After-Acquired Property

Promptly following the acquisition by the Issuer or any Guarantor of any After- Acquired Property (but subject to the limitations, if applicable, described under "—Notes Collateral" and "—ABL Collateral"), the Issuer or such Guarantor shall, if and to the extent required by the indenture, execute and deliver such mortgages, deeds of trust, security instruments, financing statements and certificates and opinions of counsel as shall be reasonably necessary to vest in the Notes Collateral Agent a perfected security interest in such After-Acquired Property and to have such After-Acquired Property added to the Notes Collateral or the ABL Collateral, as applicable, and thereupon all provisions of the indenture relating to the Notes Collateral or the ABL Collateral, as applicable, shall be deemed to relate to such After-Acquired Property to the same extent and with the same force and effect.

Information Regarding Collateral

The Issuer will furnish to the Notes Collateral Agent, with respect to the Issuer or any Guarantor, prompt written notice of any change in the Issuer or such Guarantor's (i) legal name, (ii) jurisdiction of organization or formation, (iii) identity or corporate structure or (iv) Organizational Identification Number. The Issuer and the Guarantors have agreed not to effect or permit any change referred to in the preceding sentence unless all filings have been made under the Uniform Commercial Code or otherwise that are required in order for the Notes Collateral Agent to continue at all times following such change to have a valid, legal and perfected security interest in all the Collateral. The Issuer has also agreed promptly to notify the Notes Collateral Agent of any material change with respect to the Collateral or if any material portion of the Collateral is damaged, destroyed or condemned.

Further Assurances

The Issuer and the Guarantors shall execute any and all further documents, financing statements, agreements and instruments, and take all further action that may be required under applicable law, or that the Notes Collateral Agent may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the security interests and Liens created or intended to be created by the Security Documents on the Collateral. In addition, from time to time, the Issuer will reasonably promptly secure the obligations under the indenture, the Security Documents and the Intercreditor Agreement by pledging or creating, or causing to be pledged or created, perfected security interests and Liens with respect to the Collateral. Such security interests and Liens will be created under the Security Documents and other security agreements, mortgages, deeds of trust and other instruments as contemplated by the Security Documents.

Security Documents and Certain Related Intercreditor Provisions

The Issuer, the Guarantors, U.S. Bank National Association, as collateral agent for the trustee and the holders of the notes (the "Notes Collateral Agent"), and the trustee have entered into one or more Security Documents creating and establishing the terms of the security interests and Liens that secure the notes and the Guarantees. These security interests and Liens secure the payment and performance when due of all of the Note Obligations, any other Pari Passu Lien Obligations, the Intercreditor Agreement and the Security Documents, as provided in the Security Documents. The Bank Collateral Agent and Bank Lenders secured by ABL Collateral are referred to collectively as "ABL Secured Parties." The trustee, the Notes Collateral Agent, each note holder and each other holder of, or obligee in respect of, any Note Obligations outstanding at such time are referred to collectively as the "Noteholder Secured Parties."

Table of Contents

The indenture provides that the Security Documents may be amended from time to time without the consent of the holders of the notes or the Bank Lenders to add other parties holding Other Pari Passu Lien Obligations, in each case, to the extent permitted to be incurred under the indenture and other applicable agreements. See "—Modification of the Indenture and Security Documents."

Intercreditor Agreement

On the Issue Date, the Issuer, the Guarantors, the Notes Collateral Agent and the Bank Collateral Agent entered into the Intercreditor Agreement. Although the holders of the notes and the Bank Lenders are not party to the Intercreditor Agreement, by their acceptance of the notes and ABL Obligations, respectively, they each agreed to be bound thereby.

The aggregate amount of the obligations secured by the ABL Collateral may, subject to the limitations set forth in the indenture, be increased. A portion of the obligations secured by the ABL Collateral consists or may consist of Indebtedness that is revolving in nature, and the amount thereof that may be outstanding at any time or from time to time may be increased or reduced and subsequently reborrowed and such obligations may, subject to the limitations set forth in the indenture, be increased, extended, renewed, replaced, restated, supplemented, restructured, repaid, refunded, refinanced or otherwise amended or modified from time to time, all without affecting the subordination of the Liens in favor of the Noteholder Secured Parties (relative to those of the ABL Secured Parties) or the provisions of the Intercreditor Agreement defining the relative rights of the parties thereto. The Lien priorities provided for in the Intercreditor Agreement shall not be altered or otherwise affected by any amendment, modification, supplement, extension, increase, replacement, renewal, restatement or refinancing of either the obligations secured by the ABL Collateral or the obligations secured by the Notes Collateral, by the release of any Collateral or of any guarantees securing any secured obligations or by any action that any representative or secured party may take or fail to take in respect of any Collateral.

The proceeds from the sale of any ABL Collateral remaining after the satisfaction of all ABL Obligations may not be sufficient to satisfy the Note Obligations.

The Intercreditor Agreement will have similar provisions regarding the Notes Collateral Agent's rights relative to those of the Bank Collateral Agent with respect to the Notes Collateral.

Control of Enforcement with Respect to the ABL Collateral and Application of Proceeds of ABL Collateral

Pursuant to the terms of the Intercreditor Agreement, prior to the Discharge of ABL Obligations, the Bank Collateral Agent will have the exclusive right to control the time and method by which the security interests in the ABL Collateral will be enforced, including, without limitation, following the occurrence of an Event of Default under the indenture. Prior to the Discharge of ABL Obligations, the Noteholder Secured Parties will not be permitted to enforce their security interests in the ABL Collateral even if any Event of Default under the indenture has occurred and the notes have been accelerated except (a) in any insolvency or liquidation proceeding, solely to the extent necessary to file a proof of claim or statement of interest with respect to the Note Obligations or (b) certain protective actions in order to prove, preserve, perfect or protect (but not enforce) their security interest and rights in, and the perfection and priority of their Lien on, the ABL Collateral.

Any proceeds from any ABL Collateral received in any insolvency or liquidation proceeding or pursuant to any enforcement of remedies against the ABL Collateral will be applied to repay the ABL Obligations in full (including any post-petition interest thereon whether or not allowed or allowable in any such insolvency or liquidation proceeding) until the Discharge of ABL Obligations has occurred prior to any proceeds of ABL Collateral being applied to the repayment of any Note Obligations owing to the Noteholder Secured Parties.

Table of Contents

No Duties of Bank Collateral Agent

The Intercreditor Agreement provides that no ABL Secured Party will generally have any duties or other obligations to any Noteholder Secured Party with respect to the ABL Collateral, other than serving as agent for perfection with respect to certain ABL Collateral. In addition, the Intercreditor Agreement further provides that, until the Discharge of ABL Obligations, the Bank Collateral Agent is entitled, for the benefit of the ABL Secured Parties, to sell, transfer or otherwise dispose of or deal with such ABL Collateral without regard to any security interests that are junior relative to those of the ABL Secured Parties therein or any rights to which any Noteholder Secured Party would otherwise be entitled as a result of such junior-priority security interest. Without limiting the foregoing, the trustee and the Notes Collateral Agent, as agents for the Noteholder Secured Parties, have agreed in the Intercreditor Agreement, that no ABL Secured Party will have any duty or obligation first to marshal or realize upon the ABL Collateral, or to sell, dispose of or otherwise liquidate all or any portion of the ABL Collateral, in any manner that would maximize the return to the Noteholder Secured Parties, notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of proceeds actually received by the Noteholder Secured Parties from such realization, sale, disposition or liquidation. The Intercreditor Agreement has similar provisions regarding the duties owed to the ABL Secured Parties by the Noteholder Secured Parties with respect to the Notes Collateral.

The Notes Collateral Agent, as agent for the Noteholder Secured Parties, has agreed in the Intercreditor Agreement that the Noteholder Secured Parties will waive any claim that may be had against any ABL Secured Party arising out of (i) any actions which any ABL Secured Party takes or omits to take (including actions with respect to the creation, perfection or continuation of Liens on any ABL Collateral, actions with respect to the foreclosure upon, sale, release or depreciation of, or failure to realize upon, any of the ABL Collateral and actions with respect to the collection of any claim for all or any part of the ABL Obligations from any account debtor, guarantor or any other party) or the valuation, use, protection or release of any security for such ABL Obligations, (ii) any election by any ABL Secured Party, in any proceeding instituted under Title 11 of the United States Code (the "Bankruptcy Code"), of the application of Section 1111(b) of the Bankruptcy Code or (iii) except to the extent set forth below under "—Agreements with Respect to Bankruptcy or Insolvency Proceedings," any borrowing of, or grant of a security interest or administrative expense priority under Section 364 of the Bankruptcy Code to, the Issuer or any of its Subsidiaries as debtor-in-possession. The ABL Secured Parties have agreed to waive similar claims with respect to the actions of any of the Noteholder Secured Parties pursuant to the Intercreditor Agreement.

No Interference; Payment Over; Reinstatement

The Notes Collateral Agent, as agent for the Noteholder Secured Parties, has agreed in the Intercreditor Agreement that prior to the Discharge of ABL Obligations:

•: it will not challenge or question in any proceeding the validity or enforceability of any first-priority security interest in the ABL Collateral, the validity, attachment, perfection or priority of any Lien held by any ABL Secured Party, or the validity or enforceability of the priorities, rights or duties established by or other provisions of the Intercreditor Agreement;
•: it will not take or cause to be taken any action the purpose or intent of which is, or could be, to interfere, hinder or delay, in any manner, whether by judicial proceedings or otherwise, any sale, transfer or other disposition of the ABL Collateral by any ABL Secured Party;
•: it will have no right to (A) direct any ABL Secured Party to exercise any right, remedy or power with respect to such ABL Collateral or (B) consent to the exercise by any ABL Secured Party of any right, remedy or power with respect to such ABL Collateral;

Table of Contents

•: it will not institute any suit or assert in any suit, bankruptcy, insolvency or other proceeding any claim against any ABL Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise with respect to, and no ABL Secured Party will be liable for, any action taken or omitted to be taken by any ABL Secured Party with respect to the ABL Collateral;
•: it will not object to any waiver or forbearance by the Bank Collateral Agent from or in respect of bringing or pursuing any foreclosure proceeding or action or any other exercise of any rights or remedies relating to the ABL Collateral;
•: it will not seek, and will waive any right, to have any ABL Collateral or any part thereof marshaled upon any foreclosure or other disposition of the ABL Collateral; and
•: it will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of the Intercreditor Agreement.

If any ABL Secured Party is required in any insolvency or liquidation proceeding or otherwise to turn over or otherwise pay to the estate of the Issuer or any Guarantor (or any trustee, receiver or similar Person therefor), because the payment of such amount was declared to be fraudulent or preferential in any respect or for any other reason (any amount, a "Recovery"), whether received as proceeds of security, enforcement of any right of setoff or otherwise, then as among the parties to the Intercreditor Agreement, the ABL Obligations shall be deemed to be reinstated to the extent of such Recovery and to be outstanding as if such payment had not occurred, and such holder of ABL Obligations shall be entitled to a reinstatement of such ABL Obligations with respect to all such recovered amounts and shall have all rights under the Intercreditor Agreement. If the Intercreditor Agreement was terminated (in whole or in part) prior to such Recovery, the Intercreditor Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties thereto. Any ABL Collateral received by a Noteholder Secured Party prior to the time of such Recovery shall be deemed to have been received prior to the Discharge of ABL Obligations and subject to the provisions of the immediately preceding paragraph. The ABL Secured Parties have agreed to similar limitations with respect to their rights in the Notes Collateral and their ability to bring a suit against the Notes Collateral Agent or the holders of the notes pursuant to the Intercreditor Agreement.

The trustee and the Notes Collateral Agent, as agents for the Noteholder Secured Parties, have agreed in the Intercreditor Agreement that if any Noteholder Secured Party obtains possession of the ABL Collateral or realizes any proceeds or payment in respect of the ABL Collateral, pursuant to any Security Document or by the exercise of any rights available to it under applicable law or in any bankruptcy, insolvency or similar proceeding or through any other exercise of remedies, at any time prior to the Discharge of ABL Obligations, then such Noteholder Secured Party will hold such ABL Collateral, proceeds or payment in trust for the ABL Secured Parties and transfer such ABL Collateral, proceeds or payment, as the case may be, to the Bank Collateral Agent. The trustee and the Notes Collateral Agent, as agents for the Noteholder Secured Parties have agreed in the Intercreditor Agreement that if, at any time, all or part of any payment with respect to any ABL Obligations secured by any ABL Collateral previously made shall be rescinded for any reason whatsoever, they will, upon demand therefor, promptly pay over to the Bank Collateral Agent any payment received by them (and remaining in their possession) in respect of any such ABL Collateral and shall promptly turn any such ABL Collateral then held by them over to the Bank Collateral Agent, and the provisions set forth in the Intercreditor Agreement will be reinstated as if such payment had not been made, until the payment and satisfaction in full of such ABL Obligations. The ABL Secured Parties are subject to similar limitations with respect to the Notes Collateral and any proceeds or payments in respect of any Notes Collateral pursuant to the Intercreditor Agreement.

Table of Contents

In addition, so long as the Discharge of ABL Obligations has not occurred, neither the Issuer nor any Guarantor shall grant to the Notes Collateral Agent a Lien on any assets securing any Note Obligations that are not also subject to the first-priority Lien (in the case of ABL Collateral) or second-priority Lien (in the case of Notes Collateral) in favor of the Bank Collateral Agent for the benefit of the holders of ABL Obligations. If the Notes Collateral Agent shall acquire or hold any Lien on any assets of the Issuer or a Guarantor that is not also subject to the Lien in favor of the Bank Collateral Agent for the benefit of the holders of ABL Obligations, then the Notes Collateral Agent shall, without the need for any further consent of any party and notwithstanding anything to the contrary in any other document, be deemed to also hold and have held such Lien for the benefit of the Bank Collateral Agent as security of the ABL Obligations (subject to the applicable Lien priority and other terms of the Intercreditor Agreement). The Bank Collateral Agent is subject to similar limitations and requirements in favor of the Notes Collateral Agent with respect to the Notes Collateral pursuant to the Intercreditor Agreement.

Agreements with Respect to Bankruptcy or Insolvency Proceedings

If the Bank Collateral Agent consents to financing ("DIP Financing") to be provided by one or more lenders (the "DIP Lenders") under Section 364 of the Bankruptcy Code which is to be secured by any ABL Collateral or the use of cash collateral representing proceeds of ABL Collateral under Section 363 of the Bankruptcy Code, the trustee, as agent for the Noteholder Secured Parties, has agreed in the Intercreditor Agreement that it will raise no objection to any such financing or to the Liens on the ABL Collateral securing the same ("DIP Financing Liens") or to any use of cash collateral that constitutes ABL Collateral, unless such DIP Financing, DIP Financing Liens or use of cash collateral is not permitted under the ABL Obligations so long as (among other things):

(i): either (x) all DIP Financing Liens are senior to, or rankpari passu with, the Liens of the ABL Obligations on such ABL Collateral (in which case, the Notes Collateral Agent, as agent for the Noteholder Secured Parties has agreed to subordinate the Liens of the Noteholder Secured Parties on such ABL Collateral to the Liens of the ABL Obligations on such ABL Collateral and the DIP Financing Liens) or (y) the Liens of the Notes Collateral Agent are not subordinated to such DIP Financing Liens;
(ii): the Noteholder Secured Parties retain liens on all the ABL Collateral, including proceeds thereof arising after the commencement of such proceeding, with the same priority as existed prior to the commencement of the case under the Bankruptcy Code, subject to any super-priority ranking of liens in favor of the DIP Lenders as provided above and any "carveout" for administrative expenses agreed to by the Bank Collateral Agent; and
(iii): no Noteholder Secured Party is required (without its consent) to lend or incur any monetary obligation in connection with such DIP Financing.

The ABL Secured Parties have agreed to similar provisions with respect to any DIP Financing and DIP Financing Liens related to the Notes Collateral.

Table of Contents

The trustee and the Notes Collateral Agent, as agents for each of the Noteholder Secured Parties, have agreed in the Intercreditor Agreement that they will:

(i): not object to or oppose a sale or other disposition of any ABL Collateral (or any portion thereof) under Section 363 of the Bankruptcy Code or any other provision of the Bankruptcy Code if the ABL Secured Parties shall have consented to such sale or disposition of such ABL Collateral and the proceeds of such sale or disposition are to be applied in accordance with the Intercreditor Agreement. Notwithstanding the foregoing, the Intercreditor Agreement shall not be construed to prohibit the Noteholder Secured Parties from exercising a credit bid in a sale or other disposition of ABL Collateral under Section 363 of the Bankruptcy Code;
(ii): not object to, or otherwise contest (or support any other Person contesting), any motion for relief from the automatic stay or from any injunction against foreclosure or enforcement in respect of the ABL Collateral made by the ABL Secured Parties;
(iii): until the Discharge of ABL Obligations, not seek relief from the automatic stay or any other stay in any insolvency or liquidation proceeding in respect of the ABL Collateral, without the prior written consent of the Bank Collateral Agent;
(iv): not object to, or otherwise contest (or support any Person contesting), (a) any request by the ABL Secured Parties for adequate protection on account of the ABL Collateral or (b) any objection by the ABL Secured Parties to any motion, relief, action or proceeding based on the Bank Collateral Agent's or such holder of ABL Obligations claiming a lack of adequate protection with respect to the ABL Collateral;
(v): until the Discharge of ABL Obligations, not assert or enforce (or support any Person asserting or enforcing) any claim under Section 506(c) of the Bankruptcy Codepari passu with the Liens on the ABL Collateral securing the ABL Obligations for costs or expenses of preserving or disposing of any ABL Collateral; and
(vi): not oppose or otherwise contest (or support any other Person contesting) any lawful exercise by the ABL Secured Parties of the right to credit bid at any sale of ABL Collateral.

In addition, the trustee and the Notes Collateral Agent, as agents for each of the Noteholders Secured Parties, have agreed in the Intercreditor Agreement that no Noteholder Secured Party will file or prosecute in any insolvency or liquidation proceeding any motion for adequate protection (or any comparable request for relief) based upon its respective security interests in the ABL Collateral, except that:

(i): any of them may freely seek and obtain relief granting a junior Lien co-extensive in all respects with, but subordinated to, all Liens granted in the insolvency or liquidation proceeding to, or for the benefit of, the holders of ABL Obligations (and the Intercreditor Agreement provides that the ABL Secured Parties will not object to the granting of such junior Lien); and
(ii): any of them may freely seek and obtain any relief upon a motion for adequate protection (or any comparable relief), without any condition or restriction whatsoever, at any time after the Discharge of ABL Obligations.

Without limiting the generality of any provisions of the Intercreditor Agreement, the trustee and the Notes Collateral Agent, as agents for each of the Noteholders Secured Parties, have agreed in the Intercreditor Agreement that any vote to accept, and any other act to support the confirmation or approval of, any Non-Conforming Plan of Reorganization shall be inconsistent with and, accordingly, a violation of the terms of the Intercreditor Agreement, and the Bank Collateral Agent shall be entitled to have any such vote to accept a Non-Conforming Plan of Reorganization dismissed and any such support of any Non-Conforming Plan of Reorganization withdrawn.

Table of Contents

The Notes Collateral Agent, as agent for the Noteholder Secured Parties, has agreed in the Intercreditor Agreement that (a) the Noteholder Secured Parties' claims against the Issuer and the Guarantors in respect of the ABL Collateral constitute claims secured by a Junior Lien Priority separate and apart (and of a different class) from the claims secured by a Junior Lien Priority of the holders of ABL Obligations against the Issuer and the Guarantors in respect of the ABL Collateral, (b) the ABL Obligations includes all interest that accrues after the commencement of any insolvency or liquidation proceeding of the Issuer or any Guarantor at the rate provided for in the Credit Agreement, regardless of whether a claim for post-petition interest is allowed or allowable in any such insolvency or liquidation proceeding, and (c) the Intercreditor Agreement constitutes a "subordination agreement" under Section 510 of the Bankruptcy Code. The ABL Secured Parties are subject to similar limitations in favor of the Noteholder Secured Parties pursuant to the Intercreditor Agreement.

Insurance

Until written notice by the Bank Collateral Agent to the trustee that the Discharge of ABL Obligations has occurred, as between the Bank Collateral Agent, on the one hand, and the Noteholder Secured Parties, on the other hand, only the Bank Collateral Agent will have the right (subject to the rights of the grantors under the documents related to the Credit Agreement) to adjust or settle any insurance policy or claim covering or constituting ABL Collateral in the event of any covered loss thereunder and to approve any award granted in any condemnation or similar proceeding affecting the ABL Collateral. Unless and until written notice by the trustee to the Bank Collateral Agent that the obligations under the indenture and the notes have been paid in full, as between the Bank Collateral Agent, on the one hand, and the trustee and the Notes Collateral Agent, as the case may be, on the other hand, only the Notes Collateral Agent will have the right (subject to the rights of the grantors under the documents related to the notes) to adjust or settle any insurance policy or claim covering or constituting Notes Collateral in the event of any covered loss thereunder and to approve any award granted in any condemnation or similar proceeding solely affecting the Notes Collateral. To the extent that an insured loss covers or constitutes both ABL Collateral and Notes Collateral, then the Bank Collateral Agent and the Notes Collateral Agent will work jointly and in good faith to collect, adjust or settle (subject to the rights of the grantors under the documents related to the Credit Agreement and the notes) under the relevant insurance policy.

Refinancings of the Credit Agreement and the Notes

The obligations under the Credit Agreement, and the obligations under the indenture and the notes, may be refinanced or replaced, in whole or in part, in each case, without notice to, or the consent (except to the extent a consent is otherwise required to permit the refinancing transaction under the Credit Agreement or any security document related thereto or the indenture and the Security Documents) of, the ABL Secured Parties or any Noteholder Secured Party, all without affecting the Lien priorities provided for in the Intercreditor Agreement;provided,however, that the holders of any such refinancing or replacement Indebtedness (or an authorized agent or trustee on their behalf) bind themselves in writing to the terms of the Intercreditor Agreement pursuant to such documents or agreements (including amendments or supplements to the Intercreditor Agreement) as the Bank Collateral Agent or Notes Collateral Agent, as the case may be, shall reasonably request and in form and substance reasonably acceptable to the Bank Collateral Agent or Notes Collateral Agent, as the case may be (subject, in the case of the Notes Collateral Agent, to the terms of the Security Documents and the Indenture).

In addition, if at any time in connection with or after the Discharge of ABL Obligations, the Issuer enters into any refinancing of the Credit Agreement secured by the ABL Collateral on a first-priority basis, then such Discharge of ABL Obligations shall automatically be deemed not to have occurred for all purposes of the Intercreditor Agreement, the Credit Agreement and the indenture, and the

Table of Contents

obligations under such refinancing shall automatically be treated as ABL Obligations for all purposes of the Intercreditor Agreement, including for purposes of the Lien priorities and rights in respect of ABL Collateral set forth therein.

In connection with any refinancing or replacement contemplated by the foregoing paragraph, the Intercreditor Agreement may be amended at the request and sole expense of the Issuer, and without the consent of any holder of notes, (a) to add parties (or any authorized agent or trustee therefor) provided any such refinancing or replacement Indebtedness is in compliance with the Credit Agreement and the indenture, (b) to establish that Liens on any Notes Collateral securing such refinancing or replacement Indebtedness shall have the same priority (or junior priority) as the Liens on any Notes Collateral securing the Indebtedness being refinanced or replaced and (c) to establish that the Liens on any ABL Collateral securing such refinancing or replacement Indebtedness shall have the same priority (or junior priority) as the Liens on any ABL Collateral securing the Indebtedness being refinanced or replaced, all on the terms provided for herein immediately prior to such refinancing or replacement.

Subject to the terms of the Security Documents, the Issuer and the Guarantors have the right to remain in possession and retain exclusive control of the Collateral securing the notes, to freely operate the Collateral and to collect, invest and dispose of any income therefrom. See "Risk Factors—Risks Relating to Our Level of Debt and the Notes—In the event of our bankruptcy, the ability of the holders of the notes to realize upon the Collateral will be subject to certain bankruptcy law limitations."

Release of Collateral

The Issuer and the Guarantors are entitled to the releases of property and other assets included in the Collateral from the Liens securing the notes under any one or more of the following circumstances:

•: to enable the disposition of such property or assets (other than any such disposition to the Issuer or a Restricted Subsidiary or a transaction undertaken pursuant to clause (2), (5), (7) or (8) of the definition of "Asset Sale") to the extent not prohibited under the covenant described under "—Certain Covenants—Limitation on Asset Sales";
•: in the case of a Guarantor that is released from its Guarantee, the release of the property and assets of such Guarantor; or
•: as described under "—Modification of the Indenture and Security Documents" below.

The second-priority Lien on the ABL Collateral securing the notes will terminate and be released automatically if the first-priority Lien on the ABL Collateral is released by the Bank Collateral Agent in connection with a sale, transfer or disposition of ABL Collateral that occurs in connection with the foreclosure of, or other exercise of remedies with respect to, or any sale permitted by the Credit Agreement of, such ABL Collateral by the Bank Collateral Agent (except with respect to any proceeds of such sale, transfer or disposition that remain after the Discharge of ABL Obligations and except in connection with a Discharge of ABL Obligations).

The security interests in all Collateral securing the notes and Guarantees also will be released upon (i) payment in full of the principal of, together with accrued and unpaid interest on, the notes and all other Note Obligations that are due and payable at or prior to the time such principal, together with accrued and unpaid interest, is paid or (ii) a legal defeasance or covenant defeasance under the indenture as described below under "—Legal Defeasance and Covenant Defeasance" or a discharge of the indenture as described under "—Satisfaction and Discharge."

Certain Bankruptcy Limitations

The right of the Notes Collateral Agent to repossess and dispose of, or otherwise exercise remedies in respect of, the Collateral upon the occurrence of an Event of Default is likely to be significantly impaired by applicable bankruptcy law if a bankruptcy proceeding were to be commenced by or against the Issuer or a Guarantor prior to the Notes Collateral Agent having repossessed and disposed of, or otherwise exercised remedies in respect of, the Collateral. Under the Bankruptcy Law, a secured creditor such as the Notes Collateral Agent is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from such debtor, without bankruptcy court approval. Moreover, the Bankruptcy Law permits the debtor to continue to retain and to use collateral even though the debtor is in default under the applicable debt instruments;provided that the secured creditor is given "adequate protection." The meaning of the term "adequate protection" may vary according to circumstances, but it is intended in general to protect the value of the secured creditor's interest in the collateral and may include cash payments or the granting of additional security, if and at such times as the court in its discretion determines, for any diminution in the value of the collateral as a result of the stay of repossession or disposition or any use of the collateral by the debtor during the pendency of the bankruptcy case. In view of the lack of a precise definition of the term "adequate protection" and the broad discretionary powers of a bankruptcy court, it is impossible to predict how long payment with respect to the notes could be delayed following commencement of a bankruptcy case, whether or when the Notes Collateral Agent could repossess or dispose of the Collateral or whether or to what extent holders of notes would be compensated for any delay in payment or loss of value of the Collateral.

Under the Bankruptcy Law, a claim is a secured claim up to the value of the collateral that secures it. In most cases, interest stops accruing on the date of bankruptcy, but if the collateral's value exceeds the amount of the claim, post bankruptcy petition interest will accrue up to the value of the collateral. If, on the other hand, the amount of the claim exceeds the collateral's value, the excess constitutes an unsecured claim.

Change of Control

The indenture provides that upon the occurrence of a Change of Control, each holder will have the right to require that the Issuer purchase all or a portion of such holder's notes pursuant to the offer described below (the "Change of Control Offer"), at a purchase price equal to 101% of the principal amount plus accrued interest to the date of purchase. Notwithstanding the occurrence of a Change of Control, the Issuer will not be obligated to repurchase the notes under this covenant if the Issuer has exercised its right to redeem all the notes under the terms of the section titled "Redemption—Optional Redemption."

Within 30 days following the date upon which the Change of Control occurred, the Issuer will send, by first-class mail, a notice to each holder, with a copy to the trustee, which notice shall govern the terms of the Change of Control Offer. The notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date the notice is mailed, other than as may be required by law (the "Change of Control Payment Date"). Holders electing to have a note purchased pursuant to a Change of Control Offer must surrender the note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the note completed, to the paying agent at the address specified in the notice prior to the close of business on the third business day prior to the Change of Control Payment Date.

The Issuer will not be required to make a Change of Control Offer 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 set forth in the indenture applicable to a Change of Control Offer

Table of Contents

made by the Issuer and purchases all notes validly tendered and not withdrawn under such Change of Control Offer.

If the Issuer makes a Change of Control Offer, there can be no assurance that it will have available funds sufficient to pay the Change of Control purchase price for all the notes that might be delivered by holders seeking to accept the Change of Control Offer. In the event the Issuer is required to purchase outstanding notes pursuant to a Change of Control Offer, the Issuer expects that it would seek third party financing to the extent it lacks available funds to meet its purchase obligations. However, there can be no assurance that the Issuer would be able to obtain such financing.

The trustee may not waive the covenant relating to a holder's right to have such holder's note purchased upon a Change of Control. However, the covenant and other provisions contained in the indenture relating to the Issuer's obligation to make a Change of Control Offer may be waived or modified with the written consent of the holders of a majority in principal amount of the notes. Restrictions described in the indenture on the ability of the Issuer and its Restricted Subsidiaries to incur additional Indebtedness, to grant Liens on their property, to make Restricted Payments and to make Asset Sales may also make more difficult or discourage a takeover of the Issuer, whether favored or opposed by our management. Consummation of any such transaction may require redemption or repurchase of the notes, and there can be no assurance that the Issuer or the acquiring party will have sufficient financial resources to effect such redemption or repurchase. Such restrictions and the restrictions on transactions with Affiliates may make more difficult or discourage any leveraged buyout of the Issuer or any of its Restricted Subsidiaries by our management. While such restrictions cover a wide variety of arrangements which have traditionally been used to effect highly leveraged transactions, the indenture may not afford you protection in all circumstances from the adverse aspects of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction.

The definition of "Change of Control" includes, among other transactions, a disposition of "all or substantially all" of the Issuer's property and assets. With respect to the disposition of property or assets, the phrase "all or substantially all" as used in the indenture varies according to the facts and circumstances of the subject transaction, has no clearly established meaning under relevant law and is subject to judicial interpretation. Accordingly, in certain circumstances, there may be a degree of uncertainty in ascertaining whether a particular transaction would involve a disposition of "all or substantially all" of the property or assets of a Person, and therefore it may be unclear whether a Change of Control has occurred and whether the Issuer is required to make a Change of Control Offer.

Certain Covenants

The indenture contains, among others, the following covenants:

Limitation on Incurrence of Additional Indebtedness

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, "incur"), any Indebtedness (other than Permitted Indebtedness);provided,however, that if no Default or Event of Default shall

Table of Contents

have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, the Issuer and any of its Restricted Subsidiaries that is, or upon such incurrence becomes, a Guarantor may incur Indebtedness (including, without limitation, Acquired Indebtedness) and any of its Restricted Subsidiaries that is not or will not become, upon such incurrence, a Guarantor may incur Acquired Indebtedness, in each case, if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Issuer's Consolidated Fixed Charge Coverage Ratio is greater than 2.25 to 1.0.

(b) The Issuer will not, and will not permit any Guarantor to, directly or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is expressly subordinated in right of payment to any other Indebtedness of the Issuer or such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the notes or the applicable Guarantee, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Issuer or such Guarantor, as the case may be. For purposes of the foregoing, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Issuer or any Guarantor solely by virtue of such Indebtedness being unsecured or by virtue of the fact that the holders of such Indebtedness have entered into one or more intercreditor agreements giving one or more of such holders priority over the other holders in the collateral held by them.

Limitation on Restricted Payments

The Issuer will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly,

(1): declare or pay any dividend or make any distribution (other than dividends or distributions payable in Qualified Capital Stock of the Issuer) on or in respect of shares of Capital Stock of the Issuer to holders of that Capital Stock;
(2): purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Issuer or any warrants, rights or options to purchase or acquire shares of any class of such Capital Stock;
(3): make any principal payment on, purchase, defease, redeem, prepay, decrease or otherwise acquire or retire for value, prior to any scheduled final maturity, scheduled repayment or scheduled sinking fund payment, any Indebtedness of the Issuer that is subordinate or junior in right of payment to the notes or any Guarantee (other than Indebtedness described in clause (7) of the definition of "Permitted Indebtedness"); or
(4): make any Investment (other than Permitted Investments)

(each of the actions listed above being referred to as a "Restricted Payment"), if at the time of such Restricted Payment or immediately after giving effect thereto:

(1): a Default or an Event of Default shall have occurred and be continuing; or
(2): the Issuer is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with the "Limitation on Incurrence of Additional Indebtedness" covenant; or
(3): the aggregate amount of Restricted Payments (including such proposed Restricted Payment) made on or after the Issue Date (the amount expended for such purposes, if other than in

Table of Contents

cash, being the fair market value of such property as determined reasonably and in good faith by the Issuer's Board of Directors) exceeds the sum of:

(a)

50% of the Issuer's cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) for the period (treating such period as a single accounting period) commencing on the first day of the first full fiscal quarter commencing after the Issue Date to and including the last day of the fiscal quarter ended immediately prior to the date of such calculation for which consolidated financial statements are available;plus

(b)

100% of the aggregate Net Cash Proceeds received by the Issuer from any Person (other than a Subsidiary of the Issuer) from the issuance and sale subsequent to the Issue Date of Qualified Capital Stock of the Issuer;plus

(c)

without duplication of any amounts included in clause (3)(b) above, 100% of the aggregate Net Cash Proceeds of any equity contribution received by the Issuer from a holder of its Capital Stock;plus

(d)

the amount by which the Issuer's Indebtedness or that of any of its Restricted Subsidiaries is reduced on the Issuer's balance sheet upon the conversion or exchange after the Issue Date of any of the Issuer's Indebtedness or any Indebtedness of its Restricted Subsidiaries incurred after the Issue Date into or for Qualified Capital Stock of the Issuer;plus

(e)

without duplication, the sum of:

(I): the aggregate amount returned in cash on or with respect to Investments (other than Permitted Investments) made after the Issue Date whether through interest payments, principal payments, dividends or other distributions or payments;
(II): the net cash proceeds received by the Issuer or any of its Restricted Subsidiaries from the disposition of all or any portion of such Investments (other than to a Subsidiary of the Issuer); and
(III): upon redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, the fair market value of such Subsidiary (valued in each case as provided in the definition of "Investment");

provided,however, that the sum of clauses (I), (II) and (III) above will not exceed the aggregate amount of all such Investments made by the Issuer or any of its Restricted Subsidiaries in the relevant Person or Unrestricted Subsidiary after the Issue Date.

However, the provisions set forth in the immediately preceding paragraph do not prohibit:

(1)

the payment of any dividend or other distribution within 60 days after the date of declaration of that dividend or other distribution if the dividend or other distribution would have been permitted on the date of declaration;

(2)

the acquisition of any shares of the Issuer's Capital Stock, either (a) solely in exchange for shares of the Issuer's Qualified Capital Stock or (b) through the application of net proceeds of a substantially concurrent sale for cash (other than to a Subsidiary of the Issuer) of shares of the Issuer's Qualified Capital Stock;

(3)

the acquisition of any Indebtedness of the Issuer that is subordinate or junior in right of payment to the notes or a Guarantee either:

(a): solely in exchange for shares of Qualified Capital Stock of the Issuer, or

Table of Contents

(b)

through the application of the net proceeds of a substantially concurrent sale for cash (other than to a Subsidiary of the Issuer) of:

(i): shares of Qualified Capital Stock of the Issuer; or
(ii): Refinancing Indebtedness;

(4): if no Default or Event of Default shall have occurred and be continuing, repurchases by the Issuer of Capital Stock of the Issuer from officers, directors and employees of the Issuer or any of its Subsidiaries or their authorized representatives upon the death, disability or termination of employment of such employees or termination of their seat on the Board of Directors of the Issuer, in an aggregate amount not to exceed $2.0 million in any calendar year with unused amounts in any calendar year being carried over to succeeding calendar years subject to a maximum of $4.0 million in any calendar year;
(5): if no Default or Event of Default shall have occurred and be continuing, other Restricted Payments in an aggregate amount not to exceed $25.0 million; and
(6): repurchases of Capital Stock deemed to occur upon the exercise of stock options, warrants or other convertible securities, to the extent such Capital Stock represents a portion of the consideration for such exercise.

In determining the aggregate amount of Restricted Payments made after the Issue Date in accordance with clause (3) of the immediately preceding paragraph, amounts expended pursuant to clauses (1), (2)(b), (3)(b)(i), (4) and (5) will be included in the calculation.

Not later than the date of making any Restricted Payment, the Issuer will deliver to the trustee an officers' certificate stating that such Restricted Payment complies with the indenture and setting forth in reasonable detail the basis upon which the required calculations were computed, which calculations may be based upon the Issuer's latest available internal quarterly financial statements.

Limitation on Asset Sales

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale of any assets that do not constitute ABL Collateral unless:

(1)

the Issuer or the applicable 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 sold or otherwise disposed of (as determined in good faith by the Issuer's senior management or, in the case of an Asset Sale in excess of $25.0 million, the Issuer's Board of Directors);

(2)

at least 75% of the consideration received by the Issuer or the Restricted Subsidiary, as the case may be, from such Asset Sale shall be in the form of:

(a): cash or Cash Equivalents,
(b): properties and assets to be owned by the Issuer or any of its Restricted Subsidiaries and used in a Permitted Business;provided that if the assets to be disposed of in such Asset Sale constitute Notes Collateral, such properties or assets to be owned by the Issuer or such Restricted Subsidiary constitute Notes Collateral, or
(c): Capital Stock in one or more Persons engaged in a Permitted Business that are or thereby become Restricted Subsidiaries of the Issuer;provided that if the assets to be disposed of in such Asset Sale constitute Notes Collateral, such properties or assets held by such Persons the Capital Stock of which is to be owned by the Issuer or such Restricted Subsidiary constitute Notes Collateral,

Table of Contents

and, in each case, such consideration is received at the time of such disposition;provided that the amount of

(i): any liabilities (as shown on the Issuer's or such Restricted Subsidiary's most recent balance sheet) of the Issuer or such Restricted Subsidiary (other than (A) liabilities that are unsecured or secured by Liens junior to the Lien on the Collateral securing the notes and (B) liabilities that are by their terms subordinated to the notes) that are assumed by the transferee of any such assets, and
(ii): any securities received by the Issuer or any such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash or Cash Equivalents within 90 days after such Asset Sale (to the extent of the cash or Cash Equivalents actually so converted)

shall be deemed to be cash for the purposes of this provision only;

(3): upon the consummation of such Asset Sale, the Issuer will apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof to make an Investment (i) in properties and assets that replace the properties and assets that were the subject of such Asset Sale or (ii) in properties and assets that will be used by the Issuer or a Restricted Subsidiary in a Permitted Business (clauses (i) and (ii) collectively referred to as "Replacement Assets");provided that if the assets disposed of constituted Notes Collateral, any Replacement Assets constitute Notes Collateral; and
(4): the Net Cash Proceeds from any such Asset Sale of Notes Collateral is paid directly by the purchaser thereof to the Notes Collateral Agent to be held in trust in an Asset Sale Proceeds Account for application in accordance with this covenant and, if any property other than cash or Cash Equivalents is included in such Net Cash Proceeds, such property shall be made subject to the Liens under the Security Documents.

On the 366th day after such Asset Sale or such earlier date, if any, as the Issuer's Board of Directors or of such Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clause (3) of the immediately preceding paragraph (each, a "Net Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date (each a "Net Proceeds Offer Amount") shall be applied by the Issuer or such Restricted Subsidiary to make an offer to purchase from the holders of the notes, and, if required by the terms of any Other Pari Passu Lien Obligations, from the holders of such Other Pari Passu Lien Obligations (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not less than 30 nor more than 60 days following the applicable Net Proceeds Offer Trigger Date, on apro rata basis, an amount of notes and Other Pari Passu Lien Obligations equal to the Net Proceeds Offer Amount at a price equal to 100% of the principal amount of the notes and Other Pari Passu Lien Obligations to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase.

If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary of the Issuer, as the case may be, in connection with such Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder as of the date of such conversion or disposition and the Net Cash Proceeds thereof will be applied in accordance with this covenant.

The Issuer may defer the Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $25.0 million resulting from one or more Asset Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $25.0 million, shall be applied as required pursuant to the second preceding paragraph).

Table of Contents

Notice of each Net Proceeds Offer pursuant to paragraph (a) will be mailed to the record holders as shown on the register of holders within 25 days following the Net Proceeds Offer Trigger Date, with a copy to the trustee, and will comply with the procedures set forth in the indenture. Upon receiving notice of the Net Proceeds Offer, holders may elect to tender their notes or Other Pari Passu Lien Obligations in whole or in part in denominations of $2,000 or integral multiples of $1,000 in excess thereof in exchange for cash. To the extent holders properly tender notes and Other Pari Passu Lien Obligations in an amount exceeding the Net Proceeds Offer Amount, notes and Other Pari Passu Lien Obligations of tendering holders will be purchased on apro rata basis (based on amounts tendered). To the extent that the aggregate amount of the notes and Other Pari Passu Lien Obligations tendered pursuant to a Net Proceeds Offer is less than the Net Proceeds Offer Amount, the Issuer may use such excess Net Proceeds Offer Amount for general corporate purposes or for any other purposes not prohibited by the indenture. Upon completion of any such Net Proceeds Offer, the Net Proceeds Offer Amount shall be reset at zero. A Net Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law.

(b) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly consummate an Asset Sale of ABL Collateral unless:

(1)

the Issuer 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 (as determined in good faith by the Issuer) of the assets sold or otherwise disposed of;

(2)

at least 75% of the consideration therefor received by the Issuer or such Restricted Subsidiary, as the case may be, is in the form of:

(a): cash or Cash Equivalents,
(b): properties and assets to be owned by the Issuer or any of its Restricted Subsidiaries and used in a Permitted Business;provided that the assets to be owned by the Issuer or any of its Restricted Subsidiaries constitute Collateral; or
(c): Capital Stock in one or more Persons engaged in a Permitted Business that are or thereby become Restricted Subsidiaries of the Issuer;provided that the properties and assets of such Person constitute Collateral;

and, in each case, such consideration is received at the time of such disposition;provided that the amount of

(i): any liabilities (as shown on the Issuer's or such Restricted Subsidiary's most recent balance sheet) of the Issuer or such Restricted Subsidiary (other than (x) liabilities that are unsecured or secured by Liens junior to the Lien on the Collateral securing the notes and (y) liabilities that are by their terms subordinated to the notes) that are assumed by the transferee of any such assets, and
(ii): any notes or other securities received by the Issuer or any such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash or Cash Equivalents within 90 days after such Asset Sale (to the extent of the cash received)

shall be deemed to be cash for the purposes of this provision only; and

(3)

upon the consummation of such Asset Sale, the Issuer will apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof either:

(a): reduce (x) any Indebtedness under the Credit Agreement or any Indebtedness of the Issuer or a Guarantor that in each case is secured by a Lien on the ABL Collateral that

Table of Contents

is prior to the Lien on the ABL Collateral in favor of holders of notes or (y) any Indebtedness of a Restricted Subsidiary that is not a Guarantor (and, in the case of revolving obligations under clauses (x) or (y), to correspondingly reduce commitments with respect thereto), in each case other than Indebtedness owed to the Issuer or a Subsidiary of the Issuer;

(b): make an investment in Replacement Assets; and/or
(c): a combination of prepayment and investment permitted by the foregoing clauses (3)(a) and (3)(b).

On the 366th day after an Asset Sale of ABL Collateral or such earlier date, if any, as the Board of Directors of the Issuer or of such Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (3)(a), (3)(b) and (3)(c) of the preceding paragraph (each, an "ABL Net Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which have not been applied on or before such ABL Net Proceeds Offer Trigger Date (each an "ABL Net Proceeds Offer Amount") shall be applied by the Issuer or such Restricted Subsidiary to make an offer to purchase from all holders of the notes, and, if required by the terms of any Other Pari Passu Lien Obligations, from the holders of such Other Pari Passu Lien Obligations (an "ABL Net Proceeds Offer"), on a date (the "ABL Net Proceeds Offer Payment Date") not less than 30 nor more than 60 days following the applicable ABL Net Proceeds Offer Trigger Date, on apro rata basis, an amount of notes and Other Pari Passu Lien Obligations equal to the ABL Net Proceeds Offer Amount at a price equal to 100% of the principal amount of the notes and Other Pari Passu Lien Obligations to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase.

If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary of the Issuer, as the case may be, in connection with any Asset Sale of ABL Collateral is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale of ABL Collateral as of the date of such conversion or disposition and the ABL Net Cash Proceeds thereof will be applied in accordance with this covenant.

The Issuer may defer the ABL Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $25.0 million resulting from one or more Asset Sales of ABL Collateral (at which time, the entire unutilized ABL Net Proceeds Offer Amount, and not just the amount in excess of $25.0 million, shall be applied as required pursuant to the second preceding paragraph).

Notice of each ABL Net Proceeds Offer will be mailed to the record holders as shown on the register of holders within 25 days following the ABL Net Proceeds Offer Trigger Date, with a copy to the trustee, and will comply with the procedures set forth in the indenture. Upon receiving notice of the ABL Net Proceeds Offer, holders may elect to tender their notes in whole or in part in denominations of $2,000 or integral multiples of $1,000 in excess thereof in exchange for cash. To the extent holders of notes or Other Pari Passu Lien Obligations properly tender notes in an amount exceeding the ABL Net Proceeds Offer Amount, notes of tendering holders of notes and Other Pari Passu Lien Obligations will be purchased on a pro rata basis (based on amounts tendered). To the extent that the aggregate amount of the notes and Other Pari Passu Lien Obligations tendered pursuant to an ABL Net Proceeds Offer is less than the ABL Net Proceeds Offer Amount, the Issuer may use such excess ABL Net Proceeds Offer Amount for general corporate purposes or for any other purposes not prohibited by the indenture. Upon completion of any such ABL Net Proceeds Offer, the ABL Net Proceeds Offer Amount shall be reset at zero. An ABL Net Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law.

Table of Contents

Pending the final application of any Net Proceeds pursuant to clause (b) of this covenant, the Issuer or the applicable Restricted Subsidiary may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Proceeds in any manner not prohibited by the Indenture.

(c) For the purposes of this covenant, any sale by the Issuer or a Restricted Subsidiary of the Capital Stock of a Restricted Subsidiary that owns assets constituting Notes Collateral or ABL Collateral shall be deemed to be a sale of such Notes Collateral or ABL Collateral (or, in the event of a Restricted Subsidiary that owns assets that include any combination of Notes Collateral and ABL Collateral a separate sale of each of such Notes Collateral and ABL Collateral). In the event of any such sale (or a sale of assets that includes any combination of Notes Collateral and ABL Collateral), the proceeds received by the Issuer and the Restricted Subsidiaries in respect of such sale shall be allocated to the Notes Collateral and ABL Collateral in accordance with their respective fair market values, which shall be determined by the Board of Directors of the Issuer or, at the Issuer's election, an independent third party. In addition, for purposes of this covenant, any sale by the Issuer or any Restricted Subsidiary of the Capital Stock of any Person that owns only ABL Collateral will not be subject to paragraph (a) above, but rather will be subject to paragraph (b) above.

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of notes pursuant to a Net Proceeds Offer or an ABL Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the "Asset Sale" provisions of the indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached their obligations under the "Asset Sale" provisions of the indenture by virtue thereof. The covenant and other provisions contained in the indenture relating to the Issuer's obligation to make a Net Proceeds Offer or ABL Net Proceeds Offer may be waived or modified with the written consent of the holders of a majority in principal amount of the notes.

Limitations on Dividend and Other Payment Restrictions Affecting Subsidiaries

The Issuer will not, and will not cause or permit any of its Restricted Subsidiaries (other than a Restricted Subsidiary that has executed a Guarantee) to, directly or indirectly, create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary of the Issuer to

(a): pay dividends or make any other distribution on or in respect of its Capital Stock;
(b): make loans or advances or pay any Indebtedness or other obligation owed to the Issuer or any other Restricted Subsidiary of the Issuer; or

(9): secured Permitted Indebtedness or secured Indebtedness otherwise permitted to be incurred pursuant to the covenants described under "—Limitation on Incurrence of Additional Indebtedness" and "—Limitation on Liens" that limit the right of the debtor to dispose of the assets securing such Indebtedness;
(10): customary provisions in joint venture agreements and other similar agreements entered into in the ordinary course of business;
(11): customary net worth and restrictions on transfer, assignment or subletting provisions contained in leases and other agreements entered into by the Issuer or any Restricted Subsidiary;
(12): any restriction in any agreement or instrument of a Receivables Entity governing a Qualified Receivables Transaction;provided that such restrictions apply only to such Receivables Entity or Receivables and Related Assets;
(13): any agreement governing Indebtedness incurred to Refinance the Indebtedness issued, assumed or incurred pursuant to an agreement referred to in clauses (1) through (12) above;provided,however, that the provisions relating to such encumbrance or restriction contained in any such Indebtedness, taken as a whole, are no less favorable to the Issuer in any material respect as determined by its Board of Directors in its reasonable and good faith judgment than the provisions relating to such encumbrance or restriction contained in the agreements referred to in such clauses; or
(14): any agreement governing Permitted Indebtedness or Indebtedness otherwise permitted to be incurred pursuant to the "Limitation on Incurrence of Additional Indebtedness" covenant;provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness, taken as a whole, are no less favorable to the Issuer in any material respect as determined by its Board of Directors in its reasonable and good faith judgment than the provisions contained in the Credit Agreement or in the indenture as in effect on the Issue Date.

Limitation on the Issuance and Sale of Capital Stock of Restricted Subsidiaries

The Issuer will not sell, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to issue or sell, any shares of Capital Stock of a Restricted Subsidiary (including options, warrants or other rights to purchase shares of such Capital Stock) except:

(1): to the Issuer or a Wholly Owned Restricted Subsidiary;
(2): issuance of directors' qualifying shares or sales to foreign nationals of shares of Capital Stock of the Issuer's Foreign Restricted Subsidiaries, to the extent required by applicable law;

(4): the sale or issuance of Common Stock that is Qualified Capital Stock of a Restricted Subsidiary of the Issuer, if the proceeds from such issuance and sale are applied in accordance with the "Limitation on Asset Sales" covenant.

Limitation on Issuances of Guarantees by Restricted Subsidiaries

The Issuer will not permit any of its Restricted Subsidiaries, directly or indirectly, to guarantee any of the Issuer's Indebtedness or any Indebtedness of the Issuer's Domestic Restricted Subsidiaries, unless (1) such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture to the indenture providing for a senior secured Guarantee of payment of the notes by such Restricted Subsidiary, and (2) such Restricted Subsidiary waives and will not in any manner whatsoever claim or take the benefit or advantage of any rights of reimbursement, indemnity or subrogation or any other rights against the Issuer or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee so long as any notes remain outstanding.

Notwithstanding the foregoing or the covenant set forth below under "Future Guarantors," any Guarantee by a Restricted Subsidiary may provide by its terms that it shall be automatically and unconditionally released and discharged upon

(1): any sale, exchange or transfer, to any Person not an Affiliate of the Issuer, of all of the Issuer's and each of its Restricted Subsidiary's Capital Stock in, or all or substantially all the assets of, such Restricted Subsidiary (which sale, exchange or transfer is not prohibited by the indenture),

Thereafter, such New Domestic Restricted Subsidiary shall be a Guarantor for all purposes of the indenture.

The following additional requirements shall apply:

(1): the Issuer and the new Guarantor will cause to be filed and recorded such instruments (including any financing statements) in such jurisdictions as may be required by applicable law to perfect, preserve and protect the Lien of the Security Documents on the Collateral owned by or transferred to such new Guarantor;

Table of Contents

the purpose of such merger, transfer, lease, conveyance or other disposition is not to consummate a transaction that would otherwise be prohibited by clause (3) of this covenant.

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Issuer the Capital Stock of which constitutes all or substantially all of the properties and assets of the Issuer shall be deemed to be the transfer of all or substantially all of the properties and assets of the Issuer.

The indenture provides that upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of the Issuer in accordance with the foregoing in which the Issuer is not the continuing corporation, the successor Person formed by such consolidation or into which the Issuer is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under the indenture and the notes with the same effect as if such Surviving Entity had been named as such.

The following additional conditions shall apply to each transaction described in the above paragraphs:

(1): the Issuer or the relevant Surviving Entity, as applicable, will cause to be filed such amendments or other instruments, if any, and recorded in such jurisdictions as may be required by applicable law to preserve and protect the Lien of the Security Documents on the Collateral owned by or transferred to such Person, together with such financing statements as may be required to perfect any security interests in such Collateral which may be perfected by the filing of a financing statement under the Uniform Commercial Code of the relevant states;

(4): the Issuer shall have delivered to the trustee an officers' certificate and an opinion of counsel, each stating that such transaction and, if a supplemental indenture or supplemental Security Documents, are required in connection with such transaction, such supplemental indenture and Security Documents comply with the applicable provisions of the indenture, that all conditions precedent in the indenture relating to such transaction have been satisfied and that such supplemental indenture and Security Documents are enforceable, subject to customary qualifications.

Each Guarantor (other than any Guarantor whose Guarantee is to be released in accordance with the terms of such Guarantee and the indenture in connection with any transaction complying with the provisions of "—Limitation on Asset Sales") will not, and the Issuer will not cause or permit any Guarantor to, consolidate with or merge with or into any Person other than the Issuer or any other Guarantor unless:

(1): the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made

(1) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (each an "Affiliate Transaction"), other than

(a): Affiliate Transactions permitted under paragraph (2) below and
(b): Affiliate Transactions on terms that are no less favorable than those that could reasonably have been obtained in a comparable transaction at such time on an arm's-length basis from a Person that is not an Affiliate of the Issuer or such Restricted Subsidiary.

All Affiliate Transactions (and each series of related Affiliate Transactions which are similar or part of a common plan) involving aggregate payments or other property with a fair market value in excess of $10.0 million shall be approved by the Issuer's Board of Directors or the Board of Directors of such Restricted Subsidiary, as the case may be, such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with the foregoing provisions. If the Issuer or any of its Restricted Subsidiaries enters into an Affiliate Transaction (or a series of related Affiliate Transactions related to a common plan) that involves an aggregate fair market value of more than $25.0 million, the Issuer or such Restricted Subsidiary, as the case may be, shall, prior to the consummation thereof, obtain a favorable opinion as to the fairness of such transaction or series of related transactions to the Issuer or the relevant Restricted Subsidiary, as the case may be, from a financial point of view, from an Independent Financial Advisor and file the same with the trustee.

(2) The restrictions set forth in clause (1) shall not apply to:

(a): reasonable fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or consultants of the Issuer or any Restricted Subsidiary of the Issuer as determined in good faith by the Board of Directors of the Issuer;
(b): transactions exclusively between the Issuer and any of its Restricted Subsidiaries or exclusively among such Restricted Subsidiaries,provided such transactions are not otherwise prohibited by the indenture;
(c): any agreement as in effect or entered into as of the Issue Date or any amendment thereto or any transaction contemplated thereby (including pursuant to any amendment thereto) or in any replacement agreement thereto so long as any such amendment or replacement agreement

Table of Contents

is not more disadvantageous to the holders in any material respect than the original agreement as in effect on the Issue Date;

(d): transactions effected as part of a Qualified Receivables Transaction;
(e): Restricted Payments and Permitted Investments permitted by the indenture (other than transactions with a Person that is an Affiliate other than as a result of such Investment);
(f): the issuance of securities or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans or similar employee benefit plans approved by the Board of Directors of the Issuer in good faith; and
(g): transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Issuer solely because the Issuer owns, directly or indirectly, any Capital Stock in such Person.

Reports to Holders

The indenture provides that, whether or not required by the rules and regulations of the Commission, so long as any notes are outstanding, the Issuer will file a copy of the following information and reports with the Commission for public availability (unless the Commission will not accept such a filing) and will furnish to the holders of notes and to securities analysts and prospective investors, upon their written request:

(1): all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K under the Exchange Act if the Issuer were required to file such forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Issuer and its consolidated Subsidiaries and, with respect to the annual information only, a report thereon by the Issuer's certified independent accountants; and
(2): all current reports that would be required to be filed with the Commission on Form 8-K under the Exchange Act if the Issuer were required to file such reports, in each case within the time periods specified in the Commission's rules and regulations.

In addition, whether or not required by the rules and regulations of the Commission, the Issuer will file a copy of all such information and reports with the Commission for public availability within the time periods specified in the Commission's rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon written request to the Issuer.

In addition, for so long as any notes remain outstanding, the Issuer shall furnish to the holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Impairment of Security Interest

The Issuer will not, and the Issuer will not permit any of its Restricted Subsidiaries to, take, or knowingly omit to take, any action, which action or omission would have the effect of causing a Lien to be created in favor of the collateral agent for any Other Pari Passu Lien Obligations or the Bank Lenders (in their respective capacities as such) on any property or assets of the type that would constitute Collateral unless a Lien is created in favor of the Notes Collateral Agent for the benefit of the Noteholder Secured Parties with respect to such property or assets (which Lien in favor of the Noteholder Secured Parties shall have the priority set forth in the Security Documents). Such Lien in

Table of Contents

favor of the Notes Collateral Agent for the benefit of the Noteholder Secured Parties shall at all times be in accordance with the provisions of the indenture and the Security Documents.

Events of Default

The following events are defined in the indenture as "Events of Default":

(1): the failure to pay interest on any note when the same becomes due and payable and the default continues for a period of 30 days;

(3): a default by the Issuer or any of its Restricted Subsidiaries in the observance or performance of any other covenant or agreement contained in the indenture, the Intercreditor Agreement or the Security Documents which default continues for a period of 45 days after the Issuer receives written notice specifying the default (and demanding that such default be remedied) from the trustee or the holders of at least 25% of the outstanding principal amount of the notes;
(4): the failure to pay at final stated maturity (giving effect to any applicable grace periods and any extensions thereof) the principal amount of any of the Issuer's Indebtedness or the Indebtedness of any of the Issuer's Restricted Subsidiaries, or the acceleration of the final stated maturity of any such Indebtedness by the holders thereof, if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final stated maturity or which has been accelerated, exceeds $25.0 million at any time;
(5): one or more judgments in an aggregate amount in excess of $25.0 million shall have been rendered against the Issuer or any of its Restricted Subsidiaries and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgments become final and non-appealable;
(6): certain events of bankruptcy affecting the Issuer or any of its Significant Subsidiaries;
(7): any Guarantee made by a Significant Subsidiary ceases to be in full force and effect or any Guarantee made by a Significant Subsidiary is declared to be null and void and unenforceable or any Guarantee made by a Significant Subsidiary is found to be invalid or any such Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor in accordance with the terms of the indenture); or
(8): so long as the Security Documents have not otherwise been terminated in accordance with their terms or the Collateral as a whole has not otherwise been released from the Lien of the Security Documents in accordance with the terms thereof, (a) a default by the Issuer or any Guarantor which is a Significant Subsidiary in the performance of the Security Documents which materially and adversely affects the enforceability, validity, perfection or priority of the Lien granted to the Notes Collateral Agent on the Collateral, in each case, taken as a whole, (b) a repudiation or disaffirmation by the Issuer or any Guarantor that is a Significant Subsidiary of the Issuer's or such Guarantor's material obligations under the Security Documents or (c) a Lien on any Collateral with a value in excess of $25.0 million created under any the Security Documents shall become unenforceable or invalid against the Issuer or any Guarantor that is a Significant Subsidiary for any reason.

Table of Contents

If an Event of Default (other than an Event of Default specified in clause (6) above with respect to the Issuer) shall occur and be continuing, the trustee or the holders of at least 25% in principal amount of outstanding notes may declare the principal of and accrued interest on all the notes to be due and payable by notice in writing to the Issuer and the trustee specifying the respective Event of Default and that it is a "notice of acceleration" (the "Acceleration Notice"), and the same shall become immediately due and payable.

If an Event of Default specified in clause (6) above with respect to the Issuer occurs and is continuing, then all unpaid principal of and premium, if any, and accrued and unpaid interest on all of the outstanding notes shall automatically become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder.

The indenture provides that, at any time after a declaration of acceleration with respect to the notes as described in the preceding paragraph, the holders of a majority in principal amount of the notes may rescind and cancel such declaration and its consequences:

(1): if the rescission would not conflict with any judgment or decree;
(2): if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;
(3): to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;
(4): if the Issuer has paid the trustee its reasonable compensation and reimbursed the trustee for its expenses, disbursements and advances; and
(5): in the event of the cure or waiver of an Event of Default of the type described in clause (6) of the description above of Events of Default, the trustee shall have received an officers' certificate and an opinion of counsel that such Event of Default has been cured or waived.

No such rescission will affect any subsequent Default or Event of Default or impair any right consequent thereto.

The holders of a majority in principal amount of the notes may waive any existing Default or Event of Default under the indenture, and its consequences, except a Default in the payment of the principal of or interest on any notes.

Holders of the notes may not enforce the indenture or the notes except as provided in the indenture and under the TIA. Subject to the provisions of the indenture relating to the duties of the trustee, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request, order or direction of any of the holders, unless such holders have offered to the trustee reasonable indemnity. Subject to all provisions of the indenture and applicable law, the holders of a majority in aggregate principal amount of the then outstanding notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee.

Under the indenture, the Issuer is required to provide an officers' certificate to the trustee

•: promptly upon any such officer obtaining knowledge of any Default or Event of Default, describing such Default or Event of Default and the status thereof, and
•: annually, describing whether or not such officer knows of any Default or Event of Default.

Table of Contents

No Personal Liability of Directors, Officers, Employees, Members and Stockholders

No Affiliate, director, officer, employee, limited liability company member or stockholder of the Issuer or any Subsidiary, as such, shall have any liability for any obligations of the Issuer or any Guarantor under the notes or the indenture or any Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of notes by accepting a note waives and releases all such liability. The waiver and release were part of the consideration for issuance of the notes.

Legal Defeasance and Covenant Defeasance

The Issuer may at any time elect to have its obligations and the obligations of any Guarantor discharged with respect to the outstanding notes ("Legal Defeasance"). Such Legal Defeasance means that the Issuer will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding notes, except for:

(1) the rights of holders to receive payments in respect of the principal of, premium, if any, and interest on the notes when such payments are due;

(2) the Issuer's obligations with respect to the notes concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes, and the maintenance of an office or agency for payments;

(3) the rights, powers, trust, duties and immunities of the trustee and the Issuer's obligations in connection therewith; and

(4) the Legal Defeasance provisions of the indenture.

In addition, the Issuer may at any time elect to have its obligations released with respect to certain covenants that are described in the indenture ("Covenant Defeasance"). Any omission to comply with such obligations would then not constitute a Default or Event of Default with respect to the notes. If Covenant Defeasance occurs, the Issuer's failure to perform these covenants will no longer constitute an Event of Default with respect to the notes.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1)

the Issuer must irrevocably deposit with the trustee, in trust, for the benefit of the holders cash in U.S. dollars, non-callable U.S. government obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(2)

in the case of Legal Defeasance, the Issuer must deliver to the trustee an opinion of counsel in the United States reasonably acceptable to the trustee confirming that:

(a): the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling; or
(b): since August 14, 2009, there has been a change in the applicable Federal income tax law,

in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the holders will not recognize income, gain or loss for Federal income tax purposes as a result of such Legal Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

Table of Contents

(3): in the case of Covenant Defeasance, the Issuer must deliver to the trustee an opinion of counsel in the United States reasonably acceptable to the trustee confirming that the holders will not recognize income, gain or loss for Federal income tax purposes as a result of such Covenant Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;
(4): no Default or Event of Default shall have occurred and be continuing on the date of such deposit or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;
(5): such Legal Defeasance or Covenant Defeasance must not result in a breach or violation of, or constitute a default under, the indenture, the Credit Agreement or any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound;
(6): the Issuer must deliver to the trustee an officers' certificate stating that the deposit was not made by it with the intent of preferring the holders over any other of the Issuer's creditors or with the intent of defeating, hindering, delaying or defrauding any other of the Issuer's creditors or others;
(7): the Issuer must deliver to the trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent to the Legal Defeasance or the Covenant Defeasance were complied with;
(8): the Issuer must deliver to the trustee an opinion of counsel to the effect that if no intervening bankruptcy of the Issuer occurs between the date of deposit and the 91st day following the date of the deposit and no holder is an insider of the Issuer, then after the 91st day following the date of the deposit the trust funds will not be subject to the effect of Section 547 of the United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law; and
(9): certain other customary conditions precedent are satisfied.

However, the opinion of counsel required by clause (2) above is not required if all notes not theretofore delivered to the trustee for cancellation have become due and payable, will become due and payable on the maturity date within one year or are to be called for redemption within one year under arrangements reasonably satisfactory to the trustee for the giving of notice of redemption by the trustee in the Issuer's name, and at the Issuer's expense.

Satisfaction and Discharge

The indenture will be discharged when:

(1): either (a) all the notes theretofore authenticated and delivered (except lost, stolen or destroyed notes which have been replaced or paid and notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the trustee for cancellation or (b) all notes not theretofore delivered to the trustee for cancellation (i) have become due and payable or (ii) will become due and payable within one year, or are to be called for redemption within one year, under arrangements reasonably satisfactory to the trustee for the giving of notice of redemption by the trustee in the name, and at the expense, of the Issuer, and the Issuer has irrevocably deposited or caused to be deposited with the trustee funds in an amount sufficient to pay and discharge the entire indebtedness on the notes not theretofore delivered to the trustee for cancellation, for principal of, premium, if any, and interest on the notes to the date of maturity or redemption,

Table of Contents

as the case may be, together with irrevocable instructions from the Issuer directing the trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

(2): the Issuer has paid all other sums payable under the indenture by it; and
(3): the Issuer has delivered to the trustee an officers' certificate and an opinion of counsel stating that all conditions precedent under the indenture relating to the satisfaction and discharge of the indenture have been complied with.

When the indenture is discharged, it ceases to be of further effect except for surviving rights of registration or transfer or exchange of the notes.

Modification of the Indenture and Security Documents

From time to time, the Issuer, the Guarantors, the trustee and the Notes Collateral Agent, without the consent of the holders, may amend the indenture, the Intercreditor Agreement and the Security Documents to cure ambiguities, defects or inconsistencies, and to add Guarantees, to release the Noteholder Secured Parties' Lien with respect to Collateral in accordance with the terms and conditions of the indenture, the Intercreditor Agreement and the Security Documents or similar provisions, so long as such change does not, in the good faith determination of the Issuer's Board of Directors, adversely affect the rights of any of the holders of the notes in any material respect. In addition, without the consent of the holders, the Issuer, the Guarantors, the trustee and the Notes Collateral Agent may amend the indenture, the Security Documents and the Intercreditor Agreement to provide for the release of Collateral from the Lien of the indenture and the Security Documents when permitted or required by the Security Documents, the Intercreditor Agreement or the indenture, to secure any Other Pari Passu Lien Obligations under the Security Documents and to appropriately include the same in the Intercreditor Agreement, to modify the Intercreditor Agreement to allow for Liens on the Notes Priority Collateral which secure Indebtedness secured by Junior Priority Liens that are senior to the Liens on the Notes Priority Collateral which secure the ABL Obligations, so long as such Junior Priority Liens are junior to the Liens securing the notes to the extent set forth in the definition of Junior Priority Liens (or to include such Indebtedness secured by Junior Priority Liens in the Intercreditor Agreement) or to conform the indenture, any Security Document or the Intercreditor Agreement to this Description of Notes. In making its determination, the Issuer's Board of Directors may rely on such evidence as it deems appropriate. Other modifications and amendments of the indenture may be made with the consent of the holders of a majority in principal amount of the then outstanding notes issued under the indenture, except that the consent of each holder affected thereby is required to:

(1): reduce the amount of notes whose holders must consent to an amendment;
(2): reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, on any notes;
(3): reduce the principal of or change or have the effect of changing the fixed maturity of any notes, or change the date on which any notes may be subject to redemption or reduce the redemption price therefor as described under "—Redemption";
(4): make any notes payable in money other than that stated in the notes;
(5): make any changes in provisions of the indenture protecting the right of each holder to receive payment of principal of and interest on such note on or after the due date thereof or to bring suit to enforce such payment, or permitting holders of a majority in principal amount of the notes to waive Defaults or Events of Default;
(6): modify or change any provision of the indenture or the related definitions affecting the ranking of the notes or any Guarantee in a manner which adversely affects the holders;

Table of Contents

(7): amend, change or modify in any material respect the obligation of the Issuer to make and consummate a Change of Control Offer in the event of a Change of Control which has occurred or modify any of the provisions or definitions with respect thereto after a Change of Control has occurred;
(8): make any change in the foregoing amendment provisions which require each holder's consent or in the waiver provisions; or
(9): release any Guarantor that is a Significant Subsidiary from any of its obligations under its Guarantee or the indenture other than in accordance with the terms of the indenture.

In addition, without the consent of the holders of at least 75% in principal amount of the notes then outstanding, (a) no amendment may release from the Lien of the indenture or the notes and the Security Documents all or substantially all of the Collateral otherwise than in accordance with the terms of such Security Documents and (b) no amendment to, or waiver of, the provisions of the indenture or the Security Documents may alter the priority of the Lien securing the Collateral in any manner that adversely affects the rights of the holders of the notes.

Taking and Destruction

Upon any Taking or Destruction of any Collateral, all Net Insurance Proceeds received by the Issuer or any Guarantor shall be deemed Net Cash Proceeds and shall be applied in accordance with "—Certain Covenants—Limitation on Asset Sales."

Use of Trust Monies

To the extent received by the trustee pursuant to the provisions of the indenture, the Security Documents or otherwise, all Trust Monies shall be held by the trustee as a part of the Collateral securing the notes and, so long as no Event of Default has occurred and is continuing, shall, at the Issuer's direction, be (a) applied by the trustee from time to time to the payment of the principal of, premium, if any, and interest on any notes at maturity or upon redemption or retirement, or to the purchase of notes upon tender or in the open market or otherwise, in each case in compliance with the indenture or (b) released to the extent such cash would be considered Collateral under the Security Documents following such release.

The trustee shall be entitled to apply any Trust Monies to cure any payment Event of Default. Trust Monies deposited with the trustee shall be invested in Cash Equivalents pursuant to the direction of the Issuer and, so long as no Default or Event of Default has occurred and is continuing, the Issuer shall be entitled to any interest or dividends accrued, earned or paid on such Cash Equivalents.

Governing Law

The indenture, the notes and any Guarantee are governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby.

The Trustee

U.S. Bank National Association is the trustee under the indenture and has been appointed to act as registrar and paying agent with respect to the notes. The indenture provides that, except during the continuance of an Event of Default, the trustee will perform only such duties as are specifically set forth in the indenture. During the existence of an Event of Default known to the trustee, the trustee will exercise such rights and powers vested in it by the indenture and use the same degree of care and skill in its exercise as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. The trustee is under no obligation to exercise any of its rights or powers under the

Table of Contents

indenture at the request of any holder of the notes unless such holder shall have offered the trustee security and indemnity satisfactory to it against any loss, liability or expense which might be incurred by it as a result of complying with such request.

If the trustee becomes a creditor of ours, the indenture and the provisions of the TIA limit the rights of the trustee to obtain payments of its claims or to realize on certain property received in respect of its claims. Subject to the TIA, the trustee will be permitted to engage in other transactions; however, if the trustee acquires any conflicting interest as described in the TIA, it must eliminate such conflict or resign.

We have not and will not seek a ruling from the Internal Revenue Service (the "IRS") regarding the matters discussed below, and we cannot assure you that the IRS will not challenge one or more of the tax considerations described herein.

Unless otherwise stated, this summary deals only with the new notes offered to be exchanged for old notes purchased for cash on original issue at their issue price (as defined below) and held as capital assets (generally, property held for investment) and does not address tax considerations applicable to investors that may be subject to special tax rules including banks, thrifts, real estate investment trusts, regulated investment companies, tax exempt organizations, insurance companies, dealers in securities or currencies, traders in securities that elect to use the mark-to-market method of accounting for their securities holdings, persons that will hold the notes as part of a hedging transaction, "straddle," "synthetic security" or "conversion transaction" for tax purposes, partnerships or other pass through entities for U.S. federal income tax purposes (or investors in such entities), U.S. expatriates, or U.S. holders (as defined below) that have a "functional currency" other than the U.S. dollar. If an entity treated as a partnership for United States federal income tax purposes holds the notes, the tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partner of a partnership holding the notes, you should consult your own tax advisor. Further, this summary does not discuss alternative minimum tax consequences, if any, or any state, local or foreign tax consequences to holders of the notes.

U.S. Holders of Notes

For purposes of this summary, a "U.S. holder" means the beneficial owner of a note that is for United States federal income tax purposes:

(1) an individual who is a citizen or resident of the United States,

(2) a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia,

(3) an estate, the income of which is subject to United States federal income taxation regardless of its source, or

(4) a trust if (A) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (B) it has a valid election in effect under applicable Treasury regulations to be treated as a United States person.

108

Table of Contents

The discussion herein assumes that a U.S. holder will not make an election to treat stated interest on the notes as original issue discount (as discussed below).

Stated Interest. Payments of stated interest on a note generally will be taxable to a U.S. holder as ordinary interest income at the time such payments are accrued or are received in accordance with the holder's regular method of tax accounting.

Qualified Reopening. We intend to treat, for U.S. federal income tax purposes, the issuance of the old notes on March 24, 2011 as a "qualified reopening" of the issuance under the indenture on August 14, 2009 of the original 2016 notes. Accordingly, we intend to treat, for federal income tax purposes, the old notes, and the new notes issued in exchange for old notes pursuant to this exchange offer, as having the same issue date, issue price and adjusted issue price as the original 2016 notes and therefore as having been issued with the same amount of original issue discount ("O.I.D.") for U.S. federal income tax purposes as the original 2016 notes. The issue price of the original 2016 notes was $973.69 per $1,000 of stated principal amount.

O.I.D. generally must be included in gross income (as ordinary interest income) as it accrues (on a constant yield basis), prior to the receipt of the corresponding cash (and regardless of a U.S. holder's regular method of tax accounting). Nevertheless, a U.S. holder that purchased old notes at the initial offering price of 104.5% of their stated principal amount (plus accrued interest), and which exchanges such notes for new notes pursuant to this exchange offer, should be deemed to have purchased its notes at a "premium" and therefore should not be required to include any O.I.D. in gross income.

Amortizable Bond Premium. With some exceptions, a U.S. holder may elect to amortize any bond premium paid for the notes. For this purpose, a holder is deemed to have acquired the notes at a premium if the holder's basis in the notes (immediately after their acquisition by the holder) exceeds the sum of all amounts payable on the notes after the acquisition date, other than payments of qualified stated interest. However, because we may call the notes under certain circumstances at a price in excess of their principal amount, the deduction for amortizable bond premium may be reduced or eliminated. Holders should consult their own tax advisors regarding the availability of the deduction for amortizable bond premium.

Sale, Exchange or Other Disposition of Notes. Subject to the discussion below under "The Exchange Offer," upon the sale, exchange, redemption, retirement or other taxable disposition of a note, a U.S. holder will generally recognize taxable capital gain or loss equal to the difference between (A) the amount of cash proceeds and the fair market value of any property received (except to the extent that this amount is attributable to accrued but unpaid stated interest, which is taxable as ordinary income as discussed above) and (B) the holder's adjusted tax basis in the note. The U.S. holder's adjusted tax basis in a note generally will be such holder's original cost increased by the amount of OID previously included in such holder's gross income. The gain or loss will generally be long-term capital gain or loss provided that the holder's holding period for the note exceeds one year. In the case of a holder other than a corporation, the current maximum marginal United States federal income tax rate applicable to long term capital gain recognized on the sale of a note is 15% (currently scheduled to increase to 20% for dispositions occurring during taxable years beginning on or after January 1, 2013). The deductibility of capital losses is subject to certain limitations.

The Exchange Offer. The exchange of the old notes for new notes pursuant to the exchange offer will not constitute an exchange or other taxable disposition for United States federal income tax purposes. Therefore, a holder will have the same issue price, holding period and adjusted tax basis in the new note as in the note surrendered. In addition, each holder of notes will continue to be required to include interest on the notes in its gross income in accordance with its regular method of accounting for United States federal income tax purposes, and all other United States federal income tax

109

Table of Contents

consequences of holding and disposing of new notes will be the same as the United States federal income tax consequences of holding and disposing of old notes.

Information Reporting and Backup Withholding Tax. In general, information reporting requirements will apply to payments of interest (and accruals of OID) on the notes and the proceeds of a sale or other disposition (including a retirement or redemption) of the notes. A U.S. holder will generally be subject to backup withholding (currently at a rate of 28%) on such payments and proceeds unless the holder provides to us or our paying agent a correct taxpayer identification number and certain other information, certified under penalties of perjury, or the holder otherwise establishes an exemption.

Any amounts withheld under the backup withholding rules from a payment to a U.S. holder will be allowed as a credit against the holder's United States federal income tax and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.

Non-U.S. Holders of Notes

Except as modified for estate tax purposes, for purposes of this summary, a "non-U.S. holder" means a beneficial owner of a note that is an individual, corporation, estate or trust and is not a U.S. holder (as defined above).

Qualified Reopening. As discussed in more detail in "U.S. Holders of Notes" above, we intend to treat the issuance of the old notes on March 24, 2011 for U.S. federal income tax purposes as a "qualified reopening" of the issuance on August 14, 2009 of the original 2016 notes. However, a non-U.S. holder that purchased old notes at the initial offering price of 104.5% of their stated principal amount (plus accrued interest), and which exchanges such old notes for new notes pursuant to this exchange offer, should be deemed to have purchased its notes at a "premium" should therefore not be required to include any OID in gross income.

Interest Income. Generally, interest income (which, for purposes of this discussion includes OID) of a non-U.S. holder will qualify for the "portfolio interest" exemption and therefore will not be subject to United States federal income tax or withholding tax, provided that:

(1) the non-U.S. holder does not actually (or constructively) own 10% or more of the total combined voting power of all classes of our stock entitled to vote;

(2) the non-U.S. holder is not a controlled foreign corporation that is related to us;

(3) the non-U.S. holder is not a bank whose receipt of interest on the notes is described in section 881(c)(3)(A) of the Code;

(4) such interest is not effectively connected with a U.S. trade or business of the non-U.S. holder; and

(5) either (A) the non-U.S. holder provides to us or our paying agent a properly executed IRS Form W-8BEN (or successor form), and certifies, under penalties of perjury, that it is not a United States person, or (B) the non-U.S. holder holds notes through certain foreign intermediaries and satisfies the certification requirements of applicable Treasury regulations. Special certification rules apply to certain non-U.S. holders that are entities rather than individuals.

If the non-U.S. holder cannot satisfy the requirements described above, payments of interest made to such holder will be subject to the 30% United States federal withholding tax, unless the non-U.S. holder provides to us a properly executed (1) IRS Form W-8BEN (or successor form) claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty or (2) IRS Form W-8ECI (or successor form) stating that interest paid on a note is not subject to

110

Table of Contents

withholding tax because it is effectively connected with the non-U.S. holder's conduct of a trade or business in the United States.

If any interest on the notes is effectively connected with a U.S. trade or business conducted by a non-U.S. holder, such non-U.S. holder will be subject to United States federal income tax generally in the same manner as a U.S. holder (unless an applicable income tax treaty provides otherwise). If a non-U.S. holder is eligible for the benefits of an income tax treaty between the United States and its country of residence, any "effectively connected" income will generally be subject to United States federal income tax only if it is also attributable to a permanent establishment maintained by such non-U.S. holder in the United States. If a non-U.S. holder is a corporation, that portion of its earnings and profits that is effectively connected with its U.S. trade or business also may be subject to a "branch profits tax" at a 30% rate, although an applicable income tax treaty may provide for a lower rate.

If interest received with respect to the notes is effectively connected income (whether or not a treaty applies), the 30% withholding tax described above will not apply (assuming an appropriate certification is provided).

Sale, Exchange or Disposition of Notes. Subject to the discussion of backup withholding below, a non-U.S. holder generally will not be subject to United States federal income tax or withholding tax on any gain realized on the sale, exchange, redemption, retirement, or other taxable disposition of the notes unless:

(1) the gain is effectively connected with the conduct of a United States trade or business of the non-U.S. holder (and where an income tax treaty applies, is attributable to a permanent establishment maintained by the non-U.S. holder in the United States), in which case such gain will be taxed as discussed above with respect to effectively connected interest; or

(2) in the case of a non-U.S. holder who is an individual, such holder is present in the United States for a period or periods aggregating 183 days or more during the taxable year of the disposition and certain other conditions are met, in which case (except as otherwise provided by an applicable income tax treaty) such holder will be subject to a 30% U.S. federal income tax on any gain recognized, which may be offset by certain U.S. source losses.

Information Reporting and Backup Withholding. Payments to a non-U.S. holder of interest (including OID) on a note, and amounts withheld from such payments, if any, generally will be required to be reported to the IRS and to the non-U.S. holder. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

Backup withholding (currently at a rate of 28%) generally will not apply to interest payments (including OID) on the notes to a non-U.S. holder if such holder has complied with the applicable certification requirements described in subparagraph (5) in the "Interest Income" section above or otherwise establishes an exemption under the applicable Treasury regulations.

Payment of the proceeds of a sale or other disposition (including a retirement or redemption) of a note effected by the United States office of a United States or foreign broker will be subject to information reporting requirements and backup withholding unless the non-U.S. holder properly certifies under penalties of perjury as to its foreign status or the non-U.S. holder otherwise establishes an exemption. Information reporting requirements and backup withholding generally will not apply to any payment of the proceeds of a sale or other disposition of a note effected outside the United States by a foreign office of a broker. However, unless such a broker has documentary evidence in its records that the beneficial owner is a non-U.S. holder and certain other conditions are met, or a non-U.S. holder otherwise establishes an exemption, information reporting will apply to a payment of the

111

Table of Contents

proceeds of a sale or other disposition of a note effected outside the United States by such a broker if the broker:

(1) is a United States person;

(2) derives 50% or more of its gross income for certain periods from the conduct of a trade or business in the United States;

(3) is a controlled foreign corporation for United States federal income tax purposes; or

(4) is a foreign partnership that, at any time during its taxable year, has more than 50% of its income or capital interests owned by United States persons or is engaged in the conduct of a United States trade or business.

Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules may be credited against the holder's United States federal income tax liability and any excess may be refundable if the proper information is timely provided to the IRS.

United States Federal Estate Tax. The notes will not be included in the estate of a deceased non-U.S. holder (as specifically defined for United States federal estate tax purposes) if interest payments to such non-U.S. holder would be exempt from withholding of United States federal income tax under the portfolio interest exemption discussed above (without regard to the certification requirement).

The United States federal income and estate tax discussion set forth above is included for general information only. Holders should consult their own tax advisors with respect to the tax consequences to them of the exchange, ownership and disposition of the notes, including the tax consequences under state, local, foreign and other tax laws and any proposed change in applicable laws.

PLAN OF DISTRIBUTION

Each broker-dealer that receives new notes for its own account in connection with the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of those new notes. A broker-dealer may use this prospectus, as amended or supplemented from time to time, in connection with resales of new notes received in exchange for old notes where such broker-dealer acquired old notes as a result of market-making activities or other trading activities. We have agreed that for a period of 180 days after the expiration date of the exchange offer, we will make available a prospectus, as amended or supplemented, meeting the requirements of the Securities Act to any broker-dealer for use in connection with those resales.

We will not receive any proceeds from any sale of new notes by broker-dealers. Broker-dealers may sell new notes received by them for their own account pursuant to the exchange offer from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the new notes or a combination of those methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. 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 broker-dealer or the purchasers of any new notes. Any broker-dealer that resells new notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such new notes may be deemed to be an "underwriter" within the meaning of the Securities Act. A profit on any such resale of new notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under 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.

For a period of 180 days after the expiration date of the exchange offer, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests these documents in the letter of transmittal. We will indemnify the holders of the old notes, including any broker-dealers, against specified liabilities, including liabilities under the Securities Act.

Item 22. Undertakings

The undersigned Registrant hereby undertakes:

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

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

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the

II-3

Table of Contents

Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

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

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

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

(5) The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the Prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This undertaking also includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

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