Iron Mountain

We provide information management services that help organizations around the world lower the costs, risks and inefficiencies of managing their physical and digital data. Our solutions enable customers to protect and better use their information—regardless of its format, location or lifecycle stage—so they can optimize their business and ensure proper recovery, compliance and discovery. We offer comprehensive records management services, data protection & recovery services and information destruction services, along with the expertise and experience to address complex information management challenges such as rising storage costs, litigation, regulatory compliance and disaster recovery. Founded in an underground facility near Hudson, New York in 1951, Iron Mountain is a trusted partner to more than 147,000 corporate clients throughout North America, Europe, Latin America and Asia Pacific. We have a diversified customer base comprised of commercial, legal, banking, healthcare, accounting, insurance, entertainment and government organizations, including more than 95% of the Fortune 1000. As of December 31, 2010, we provided services in more than 35 countries on five continents, employed over 18,000 people and operated more than 1,000 facilities.

Now in our 60th year, we have experienced tremendous growth, particularly since successfully completing the initial public offering of our common stock in February 1996. We have grown from a business with limited product offerings and annual revenues of $104.0 million in 1995 into a global enterprise providing a broad range of information management services to customers in markets around the world with total revenues of more than $2.9 billion for the year ended December 31, 2010. On January 5, 2009, we were added to the S&P 500 Index and as of December 31, 2010 we were number 644 on the Fortune 1000.

Our success since becoming a public company in 1996 has been driven in large part by our execution of a consistent long-term growth plan to build market leadership by extending our strategic position through service line and global expansion. This growth plan has been sequenced into three phases. The first phase involved establishing leadership and broad market access in our core businesses: records management and data protection & recovery, primarily through acquisitions. In the second phase we invested in building a successful selling organization to access new customers, converting previously unvended demand. While different parts of our business are in different stages of evolution along our three-phase strategy, as an enterprise, we have transitioned to the third phase of our growth plan, which we call the capitalization phase. In this phase, which we expect will run for a long time to come, we seek to expand our relationships with our customers to continue solving their increasingly complex information management problems. Doing this well means expanding our service offerings on

S-1

a global basis while maximizing our solid core businesses. In doing this, we continue to build what we believe to be a very durable business through disciplined execution.

Consistent with this strategy, we have transitioned from a growth strategy driven primarily by acquisitions of information management services companies to expansion driven primarily by internal growth. In 2001, internal revenue growth exceeded growth through acquisitions for the first time since we began our acquisition program in 1996. This has continued to be the case in each year since 2001 with the exception of 2004. In the absence of unusual acquisition activity, we expect to achieve more of our revenue growth internally in 2011 and beyond.

We expect to achieve our long-term growth goals by offering our customers integrated services that address their increasingly complex information management needs regardless of the format, location or lifecycle stage of their information. By doing so we aim to help our customers reduce the costs, risks and complexities associated with managing their data while increasing their compliance with various laws, regulations, company policies and industry best practices. Consistent with our overall growth strategy, we are focused on improving our internal revenue growth trajectory in the near-term primarily through a set of specific growth initiatives. Our go-to-market initiative is a targeted approach to improving our sales capability. By successfully executing on this initiative, we expect to increase revenues with our existing customers by selling them new services and by gaining new customers that today do not outsource some or all of their information management service needs. We are also targeting higher growth in our international businesses as we expand our platform for selling core services and new services in higher growth markets. Finally, we are continuing to expand our services portfolio in the hybrid market to capture what we see as larger, faster growing opportunities.

Our information management services can be broadly divided into three major service categories: records management services, data protection & recovery services, and information destruction services. Media formats can be broadly divided into physical and electronic records. We define physical records to include paper documents, as well as all other non-electronic media such as microfilm and microfiche, master audio and videotapes, film, X-rays and blueprints. Electronic records include email and various forms of magnetic media such as computer tapes and hard drives and optical disks.

Our records management services include: records management program development and implementation based on best-practices to help customers comply with specific regulatory requirements, implementation of policy-based programs that feature secure, cost-effective storage for all major media, including paper (which is the dominant form of records storage), flexible retrieval access and retention management. Included within records management services are our hybrid services. These services help organizations to gain better access to, and ultimately control over, their paper records by digitizing, indexing and hosting them in online archives to provide complete information lifecycle solutions. Within the records management services category, we have developed specialized services for vital records and regulated industries such as healthcare, energy, government and financial services.

Our data protection & recovery services include disaster preparedness, planning, support and secure, off-site vaulting of data backup media for fast and efficient data recovery in the event of a disaster, human error or virus. Our technology-based data protection & recovery services include online backup and recovery solutions for desktop and laptop computers and remote

servers. After the sale of our online backup and recovery, digital archiving and eDiscovery solutions businesses (the "Digital Business"), we offer these services primarily through partnerships. Additionally, we serve as a trusted, neutral third party and offer intellectual property escrow services to protect and manage source code and other proprietary information.

Our information destruction services are comprised almost exclusively of secure shredding services. Secure shredding services complete the lifecycle of a record and involve the shredding of sensitive documents in a way that ensures privacy and a secure chain of custody for the records. These services typically include either the scheduled pick-up of loose office records which customers accumulate in specially designed secure containers we provide or the shredding of documents stored in records facilities upon the expiration of their scheduled retention periods.

Financial characteristics of our business

Our financial model is based on the recurring nature of our various revenue streams. The historical predictability of our revenues and the resulting adjusted operating income before depreciation, amortization, goodwill impairment and (gain) loss on disposal/writedown of property, plant and equipment, net, or Adjusted OIBDA(1), allow us to operate with a high degree of financial leverage. Our business has the following financial characteristics:

•

Recurring revenues.  We derive a majority of our consolidated revenues from fixed periodic, usually monthly, fees charged to customers based on the volume of records stored. Once a customer places physical records in storage with us and until those records are destroyed or permanently removed (for which we typically receive a service fee), we receive recurring payments for storage fees without incurring additional labor or marketing expenses or significant capital costs. Similarly, contracts for the storage of electronic backup media consist primarily of fixed monthly payments. Our annual revenues from these fixed periodic storage fees have grown for 22 consecutive years. For each of the three years 2008 through 2010, storage revenues, which are stable and recurring, have accounted for over 52% or more of our total consolidated revenues. This stable and growing storage revenue base also provides the foundation for increases in service revenues and Adjusted OIBDA.

•

Historically non-cyclical storage business.  Historically, we have not experienced any significant reductions in our storage business as a result of economic downturns although, during recent economic slowdowns, the rate at which some customers added new cartons to their inventory was below historical levels. We believe that companies that have outsourced records management services are less likely during economic downturns to incur the move-out costs and other expenses associated with accelerating destruction of their records,

---

(1)   We use Adjusted OIBDA, an integral part of our internal planning and reporting systems, to evaluate the operating performance of our business. As such, we believe Adjusted OIBDA provides our current and potential investors with relevant and useful information regarding our ability to generate cash flow to support our business. Additionally, we use multiples of current and projected Adjusted OIBDA in conjunction with our discounted cash flow models to determine our overall enterprise valuation and to evaluate acquisition targets. Adjusted OIBDA should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America, or GAAP, such as operating or net income (loss) or cash flows from operating activities (as determined in accordance with GAAP). For a more detailed definition and reconciliation of Adjusted OIBDA and a discussion of why we believe this measure provides relevant and useful information to our current and potential investors, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Measures" in our Current Reports on Form 8-K filed September 19, 2011, which are incorporated herein by reference.

    switching vendors or moving their records management services programs in-house. However, during the current economic downturn, which is more severe and has lasted longer than other recent downturns, destruction rates have increased as some customers have been more willing to incur additional short-term service costs in exchange for lower storage costs in the long-term. In addition, we have experienced longer sales cycles and lower incoming volumes from existing customers, due in large part we believe to high unemployment rates and generally lower levels of business activity. Combined, these impacts have resulted in lower net volume growth rates in the short-term. The net effect of these factors has been the continued growth of our storage revenue base, albeit at a lower rate. For each of the three years 2008 through 2010, total net volume growth has ranged from between 1% to 6% on a global basis.

•

Inherent growth from existing physical records customers.  Our physical records customers have, on average, sent us additional cartons at a faster rate than stored cartons have been destroyed or permanently removed. However, in the current economic downturn, elevated destruction and withdrawal rates have resulted in lower net volume growth in recent quarters. We believe the continued growth of our physical records storage revenues is the result of a number of factors, including: (1) the trend toward increased records retention; (2) customer satisfaction with our services; (3) the costs and inconvenience of moving storage operations in-house or to another provider of information management services; and (4) our positive pricing actions.

•

Diversified and stable customer base.  As of December 31, 2010, we had over 147,000 corporate clients in a variety of industries. We currently provide services to commercial, legal, banking, healthcare, accounting, insurance, entertainment and government organizations, including more than 95% of the Fortune 1000. No customer accounted for as much as 2% of our consolidated revenues in any of the years ended December 31, 2008, 2009 and 2010. For each of the three years 2008 through 2010, the average volume reduction due to customers terminating their relationship with us was less than 2%.

•

Capital expenditures related primarily to business line growth and ongoing operations.  Our business requires significant capital expenditures to support our expected revenue growth and ongoing operations as well as new products and services and increased profitability. As the nature of our business has evolved over time, so has the nature of our capital expenditures. Every year we expend capital to support a number of different objectives. The majority of our capital goes to support business line growth and our ongoing operations. We also expend capital to support the development and improvement of products and services and projects designed to increase our profitability. These expenditures are generally smaller and more discretionary in nature. Below are descriptions of the major types of capital expenditures we are likely to make in a given year:

•

Capital to support business line growth—these expenditures are primarily related to capacity expansion. This includes investments in new building outfitting, carton storage systems, tape storage systems and containers, shredding plants and bins and technology service storage and processing capacity.

•

Capital to support ongoing business operations—these expenditures are primarily related to major repairs and/or the replacement of assets such as facilities, warehouse equipment and computers, previously referred to as maintenance capital expenditures. This category

also includes operational support initiatives such as sales and marketing and information technology projects to support infrastructure requirements.

•

Capital for new product development—these expenditures are directly related to the development of new products or services in support of our integrated value proposition.



•

Capital for product improvement—these expenditures are primarily related to product and service enhancements that support our leadership position in the various markets in which we operate. Spending in this area includes items such as increased feature functionality, security upgrades or system enhancements.



•

Capital to support operational efficiencies—these expenditures are primarily related to driving increased profitability through cost savings and operating efficiencies and include items such as facility consolidations and systems to support operating process improvements.



•

Capital to acquire/construct real estate—these expenditures are directly related to the acquisition of real estate, either through the purchase of a new facility or the exercise of a purchase option in an existing lease, or the construction of a new facility.

Following is a table presenting our capital expenditures(1) for 2008, 2009 and 2010 organized by the nature of the spending as described above:

We believe that capital expenditures incurred as a percent of revenues is a meaningful metric for investors as it indicates the efficiency with which we are investing in the growth and operational efficiency of our business. For the years 2008 through 2010, our total capital expenditures incurred as a percent of revenues were approximately 12%, 11% and 8%, respectively. The decrease in capital expenditures as percent of revenues since 2008 is due primarily to our disciplined approach to capital management, a mix shift toward less capital intense service revenues and moderating growth rates in our physical storage business.

Following is a table presenting our capital expenditures(1) as a percent of total revenues for 2008, 2009 and 2010 organized by the nature of the spending as described above:

Growth strategy

We offer our customers an integrated value proposition by providing them with comprehensive records management services, data protection & recovery services and information destruction services, along with the expertise and experience to address complex information management challenges such as rising storage costs, litigation, regulatory compliance and disaster recovery. We expect to maintain a leadership position in the information management services industry

around the world by enabling customers to protect and better use their information—regardless of its format, location or lifecycle stage—so they can optimize their business and ensure proper recovery, compliance and discovery.

In the U.S. and Canada, we seek to be one of the largest information management services providers in each of our markets. Internationally, our objectives are to continue to capitalize on our expertise in the information management services industry and to make additional acquisitions and investments in selected international markets. Our near-term growth objectives are comprised of a set of specific initiatives including: (1) our go-to-market initiative, which is a targeted, low risk approach to improving our sales capability and thereby increasing revenues with our existing customers by selling them new services and gaining net new customers that today are unvended; (2) higher growth in our international businesses as we expand our platform for selling core services and new services in higher growth markets; and (3) continuing to expand our services portfolio in the hybrid market to capture those larger, faster growing opportunities. Although the focus will be on growing our business organically, targeted acquisitions will continue to play a role in our overall growth strategy.

Introduction of new products and services

We continue to expand our portfolio of products and services. Adding new products and services allows us to further penetrate our existing customer accounts and attract new customers in previously untapped markets.

Growth from existing customers

Our existing customers' storage of physical records contributes to storage and storage-related service revenues' growth because, on average, they generate additional cartons at a faster rate than old cartons are destroyed or permanently removed. In order to maximize growth opportunities from existing customers, we seek to maintain high levels of customer retention by providing premium customer service through our local account management staff.

Our sales coverage model is designed to identify and capitalize on incremental revenue opportunities by allocating our sales resources based on a sophisticated segmentation of our customer base and selling additional records management, data protection & recovery and information destruction services, in new and existing markets, within our existing customer relationships. We also seek to leverage existing business relationships with our customers by selling complementary services and products. Complementary services include special project work, data restoration projects, fulfillment services, consulting services, technology services and product sales (including specially designed storage containers and related supplies). In addition, included in complementary services revenue is recycled paper revenue.

Addition of new customers

Our sales forces are dedicated to three primary objectives: (1) establishing new customer account relationships; (2) generating additional revenue from existing customers in new and existing markets; and (3) expanding new and existing customer relationships by effectively selling a wide array of complementary services and products. In order to accomplish these objectives, our sales forces draw on our U.S. and international marketing organizations and senior management.

Growth through acquisitions

The goals of our current acquisition program are to supplement internal growth by expanding our new service capabilities and industry-specific services and continue to expand our presence in targeted international markets. We have a successful record of acquiring and integrating information management services companies.

Acquisitions in the North American physical business segment

We substantially completed our geographic expansion in North America in 2003. Given the small number of attractive acquisition targets in our core physical businesses in North America and our increased revenue base, future acquisitions are expected to be less significant to our overall North American revenue growth than in the past.

Acquisitions in the international physical business segment

We substantially completed our geographic expansion in Europe and Latin America by 2003 and began our expansion into Asia Pacific in 2005. We expect to continue to make acquisitions and investments in information management services businesses outside North America. We have acquired and invested in, and seek to acquire and invest in, information management services companies in countries, and, more specifically, markets within such countries, where we believe there is potential for significant growth. Future acquisitions and investments will focus primarily on developing priority expansion markets in Continental Europe and Asia, with continued leverage of our successful joint venture model. Similar to our strategy in North America, we will also explore international acquisitions that strengthen our capabilities in areas such as hybrid services and industry-specific services.

The experience, depth and strength of local management are particularly important in our international expansion and acquisition strategy. Since beginning our international expansion program in January 1999, we have, directly and through joint ventures, expanded our operations into more than 35 countries in Europe, Latin America and Asia Pacific. These transactions have taken, and may continue to take, the form of acquisitions of an entire business or controlling or minority investments, with a long-term goal of full ownership. We believe our joint venture strategy, rather than an outright acquisition, may, in certain markets, better position us to expand the existing business. The local partner benefits from our expertise in the information management services industry, our multinational customer relationships, our access to capital and our technology, and we benefit from our local partners' knowledge of the market, relationships with local customers and their presence in the community. In addition to the criteria we use to evaluate North American acquisition candidates, when looking at an international investment or acquisition, we also evaluate the presence in the potential market of our existing customers as well as the risks uniquely associated with an international investment, including those risks described below.

Our long-term goal is to acquire full ownership of each business in which we made a joint venture investment. Since 2007, we acquired the remaining minority equity ownership in our Brazilian (2008), Greek (2010), Chinese (2010), Hong Kong (2010) and Singapore (2010) operations. In 2010, to better align our operations with our long-term international growth objectives, we divested our ownership stakes in Indonesia and Sri Lanka. We now own more than 98% of our international operations, measured as a percentage of consolidated revenues.

Our international investments are subject to risks and uncertainties relating to the indigenous political, social, regulatory, tax and economic structures of other countries, as well as fluctuations in currency valuation, exchange controls, expropriation and governmental policies limiting returns to foreign investors.

The amount of our revenues derived from international operations and other relevant financial data for fiscal years 2008, 2009 and 2010 are set forth in Note 9 to Notes to Consolidated Financial Statements in the current report on Form 8-K filed on September 19, 2011. For the years ended December 31, 2008, 2009 and 2010, we derived approximately 34%, 31% and 33%, respectively, of our total revenues from outside of the U.S. As of December 31, 2008, 2009 and 2010, we have long-lived assets of approximately 31%, 34% and 36%, respectively, outside of the U.S.

Recent developments

Strategic plan

In April 2011, we announced a three-year strategic plan to increase shareholder value. The key components of our plan are: (i) sustaining a leadership position in our high-return North America business; (ii) driving substantial improvements in our international portfolio; (iii) focusing on our core business and exploring strategic alternatives for our digital business; and (iv) committing to significant shareholder payouts of $2.2 billion through 2013 with $1.2 billion being paid out through May 2012.

Discontinued operations

In June 2011, we completed the sale of our Digital Business to Autonomy Corporation plc for approximately $395.4 million in cash, consisting of the initial purchase price of $380.0 million and a preliminary working capital adjustment of approximately $15.4 million, which remains subject to customary post-closing adjustment based on the amount of working capital at closing. We intend to continue to deliver technology services to solve our customers' digital information management challenges through partnerships. Additionally, in connection with our strategic portfolio review of certain international operations, we have decided to divest our New Zealand operations.

As a consequence of the sale of our Digital Business and decision to sell our New Zealand operations, we are required to reflect those businesses as "discontinued operations" retroactively in our historical financial statements. On September 19, 2011, we filed two current reports on Form 8-K (the "September 8-Ks") with the SEC in order to recast our previously filed annual financial statements for the fiscal year ended December 31, 2010 and our interim financial statements for the quarter ended March 31, 2011, and to make changes in the corresponding Management's Discussion and Analysis of Financial Condition and Results of Operations, our historical segment reporting and other related changes to reflect the discontinued operations.

The information included in the September 8-Ks supersede the corresponding information we previously filed with the SEC in our annual report on Form 10-K for the fiscal year ended December 31, 2010 and our quarterly report on Form 10-Q for the quarter ended March 31, 2011.

Possible impairment charge

In September 2011, as a result of certain changes we made in the manner in which our European operations will be managed, we reorganized our reporting structure and reassigned goodwill among the revised reporting units. Previously, we tested goodwill impairment at the European level on a combined basis. As a result of the management and reporting changes, we concluded that we have three reporting units for our European operations, consisting of (1) the United Kingdom, Ireland and Norway ("UKI"), (2) Belgium, France, Germany, Italy, Luxembourg, Netherlands and Spain ("Western Europe") and (3) the remaining countries in Europe ("Central Europe"). Due to these changes, we will perform all future goodwill impairment analysis on the new reporting unit basis. The total assets of UKI, Western Europe and Central Europe amounted to approximately $798.0 million, $365.0 million and $207.0 million, respectively, as of July 31, 2011. As a result of the restructuring of our reporting units, we concluded that we had an interim triggering event and, therefore, we are performing an interim goodwill impairment test for UKI, Western Europe and Central Europe in the third quarter of 2011. Based on our current analyses, we believe our UKI and Central Europe reporting units are properly valued. Total long-lived assets of the Western Europe reporting unit are $310.0 million, including approximately $111.0 million of allocated goodwill, as of July 31, 2011. We are in the early stages of our analysis but based on information and work performed to date, we may record an impairment charge associated with goodwill, customer relationship and property, plant and equipment (primarily racking) long-lived assets in our Western Europe reporting unit. We estimate any charge associated with the long-lived assets of the Western Europe reporting unit to be in the range of $0.0 million to $100.0 million on a pretax basis. In conjunction with our third quarter 2011 filing on Form 10-Q, we expect to record our preliminary estimate of any impairment charges based on work completed through the time of our filing. We anticipate finalizing any change to the estimated impairment charge, if any, in the fourth quarter of 2011, which will be included in our 2011 annual report on Form 10-K. The estimated range is based on the analyses we performed to date, and is subject to change and refinement as we complete our analyses. Accordingly, we cannot provide any assurance as to the actual impairment charge we may record or that it will fall within the range set forth above.

Address and telephone number

We were incorporated in 1990, but our operations date from 1951. We are a Delaware corporation. Our principal place of business is located at 745 Atlantic Avenue, Boston, Massachusetts 02111, and our telephone number is (617) 535-4766.

Risk Factors" in our current report on Form 8-K filed on September 19, 2011 and our quarterly report on Form 10-Q for quarter ended March 31, 2011, which are incorporated herein by reference, and other information in and incorporated in this prospectus supplement and the accompanying prospectus before deciding to invest in our notes.

Our substantial indebtedness could adversely affect our financial health and prevent us from fulfilling our obligations under our various debt instruments.

We have now, and after the offering will continue to have, a significant amount of indebtedness. The following table shows important credit statistics as of June 30, 2011, and assumes that this offering was completed on June 30, 2011 and the net proceeds were applied as described under "Use of proceeds":

Our substantial indebtedness could have important consequences to you. Our indebtedness may increase as we continue to borrow under existing and future credit arrangements in order to finance future acquisitions and for general corporate purposes, which would increase the associated risks. These risks include:

•

inability to satisfy our obligations with respect to our various debt instruments;

•

inability to adjust to adverse economic conditions;

•

inability to fund future working capital, capital expenditures, acquisitions and other general corporate requirements, including possible required repurchases of our various indebtedness;

•

limits on our flexibility in planning for, or reacting to, changes in our business and the information management services industry;

•

limits on future borrowings under our existing or future credit arrangements, which could affect our ability to pay our indebtedness, including the notes, or to fund our other liquidity needs;

•

inability to generate sufficient funds to cover required interest payments, including on the notes; and

•

restrictions on our ability to refinance our indebtedness on commercially reasonable terms.

Restrictive loan covenants may limit our ability to pursue our growth strategy.

Our credit facility and our indentures contain covenants restricting or limiting our ability to, among other things:

•

incur additional indebtedness;

S-13

---

Table of Contents

•

pay dividends or make other restricted payments;

•

make asset dispositions;

•

create or permit liens; and

•

make capital expenditures and other investments.

These restrictions may adversely affect our ability to pursue our acquisition and other growth strategies.

We may not have the ability to raise the funds necessary to finance the repurchase of outstanding senior subordinated indebtedness, including the notes, upon a change of control event as required by the indenture for the notes and our indentures for our other existing senior subordinated notes.

Upon the occurrence of a Change of Control (as defined in "Description of the notes"), we will be required to offer to repurchase all outstanding notes and all of our other existing senior subordinated indebtedness. However, it is possible that we will not have sufficient funds at the time of the Change of Control to make the required repurchase of the notes or that restrictions in our revolving credit facility will not allow such repurchases. In addition, certain important corporate events, such as leveraged recapitalizations that would increase the level of our indebtedness, would not constitute a Change of Control under our indentures. See "Description of the notes—Repurchase at the option of holders—Change of control."

Despite current indebtedness levels, we and our subsidiaries may still be able to incur substantially more debt.

The terms of our indentures generally do not prohibit us from borrowing additional funds under our revolving credit facility and possible future credit arrangements. Our existing term loans and credit facilities would permit additional borrowings, under such facilities (subject to customary borrowing conditions) or otherwise, of up to $718.3 million as of June 30, 2011, assuming we had completed this offering on June 30, 2011 and applied the net proceeds as described under "Use of proceeds." Additional borrowings under such facilities would be, and other borrowings could be, senior to the notes and the guarantees.

Our ability to generate sufficient cash to service our indebtedness depends on many factors beyond our control.

Our ability to make payments on and to refinance our indebtedness, including the notes, and to fund capital expenditures and future acquisitions will depend on our ability to generate cash in the future. This, to some extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. We believe our cash flow from continuing operations and available borrowings under our existing and future credit arrangements will be adequate to meet our foreseeable future liquidity needs.

We cannot assure you, however, that our business will generate sufficient cash flow from continuing operations or that future borrowings will be available to us under our existing and future credit arrangements in an amount sufficient to enable us to pay our indebtedness, including the notes, or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness, including the notes, on or before maturity. We cannot assure you

S-14

Table of Contents

that we will be able to refinance any of our indebtedness, including our revolving credit facility and the notes, on commercially reasonable terms or at all.

The notes and the subsidiary guarantees are junior to all of our and our subsidiary guarantors' current and future senior indebtedness and possibly to all of our or their future borrowings, and in some situations, this may reduce our ability to fulfill our full obligations under the notes.

The notes and the subsidiary guarantees rank behind all of our and our subsidiary guarantors' current and future senior indebtedness, and pari passu with our and our subsidiary guarantors' current and future senior subordinated indebtedness and trade payables. As a result, upon any distribution to our creditors or the creditors of the guarantors in a bankruptcy, liquidation or reorganization or similar proceeding relating to us or the guarantors or our or their property, the holders of our and the guarantors' senior debt will be entitled to be paid in full in cash before any payment may be made with respect to the notes or the guarantees.

In addition, all payments on the notes and the guarantees will be blocked in the event of a payment default on our senior debt and may be blocked for up to 179 of 360 consecutive days in the event of certain non-payment defaults on our senior debt.

If we or the guarantors become subject to a bankruptcy, liquidation or reorganization or similar proceeding, holders of the notes will participate with trade creditors and all other holders of our and the guarantors' senior subordinated indebtedness in the assets remaining after we and the guarantors have paid all of the senior debt. However, because the indenture requires that amounts otherwise payable to holders of the notes in a bankruptcy or similar proceeding be paid to holders of senior debt instead, holders of the notes may receive less, ratably, than holders of trade payables in any such proceeding. In any of these cases, we and the guarantors may not have sufficient funds to pay all of our and their creditors and holders of the notes may receive less, ratably, than the holders of senior debt.

Assuming we had completed this offering on June 30, 2011, these notes and the subsidiary guarantees would have been subordinated to $592.6 million of our and our subsidiary guarantors' senior debt and would have ranked equally with $2,295.5 million (includes $6.1 million of net discounts) of our other senior subordinated debt and trade payables (Canada Company is an obligor with respect to $181.1 million of this debt; Canada Company will not guarantee the notes offered hereby or our other senior subordinated debt). We will be permitted to incur substantial additional indebtedness, including senior debt, in the future under the terms of the indenture.

Your right to receive payments on these notes could be adversely affected if any of our non-guarantor subsidiaries declare bankruptcy, liquidate or reorganize.

Substantially all of our direct and indirect wholly owned domestic subsidiaries will guarantee the notes. Canada Company, Iron Mountain Europe (Group) Limited, or IME, their respective subsidiaries and our other existing international subsidiaries do not, and we anticipate that our future international subsidiaries, will not, guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those non-guarantor subsidiaries before any assets are made available for distribution to us. Assuming this offering had been completed on June 30, 2011, these notes

S-15

Table of Contents

were effectively junior to $359.7 million of indebtedness and other liabilities (including trade payables) of our non-guarantor subsidiaries. Our non-guarantor subsidiaries generated 33% of our consolidated revenues in the year ended December 31, 2010 and 35% of our consolidated revenues in the six-month period ended June 30, 2011 and held 39% of our consolidated total assets as of June 30, 2011, in the latter case without reduction for noncontrolling interests in certain of our international subsidiaries.

Our condensed consolidating financial information included in the notes to our consolidated financial statements, which we have incorporated by reference from our quarterly report on Form 10-Q for the quarter ended June 30, 2011 and our current reports on Form 8-K filed September 19, 2011, includes information for Iron Mountain, our subsidiary guarantors on a combined basis, Canada Company, and our non-guarantor subsidiaries on a combined basis.

Federal and state statutes could allow courts, under specific circumstances, to void guarantees and require holders of the notes to return payments received from guarantors.

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

•

received less than reasonably equivalent value or fair consideration for the incurrence of such guarantee; and

•

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

•

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

•

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

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

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

•

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

•

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

•

it could not pay its debts as they become due.

On the basis of historical financial information, recent operating history and other factors, we believe that each guarantor, after giving effect to its guarantee of the notes, will not be insolvent, will not have unreasonably small capital for the business or any transaction in which

S-16

---

Table of Contents

it is engaged and will not have incurred debts beyond its ability to pay such debts as they mature. There can be no assurance, however, as to what standard a court would apply in making such determinations or that a court would agree with our conclusions in this regard.

Some or all of the guarantees of the notes may be released automatically.

A subsidiary guarantor may be released from its guarantee at any time upon a sale, exchange or transfer, in compliance with the provisions of the indenture for the notes, of the capital stock of such subsidiary guarantor or of substantially all of the assets of such subsidiary guarantor. In addition, in some other circumstances, a subsidiary guarantor may be released from its subsidiary guarantee in connection with our designation of such subsidiary guarantor as an unrestricted subsidiary or excluded restricted subsidiary. See "Description of the notes—Certain covenants—Additional subsidiary guarantees."

Since Iron Mountain is a holding company, our ability to make payments on the notes depends in part on the operations of our subsidiaries.

We are a holding company, and substantially all of our assets consist of the stock of our subsidiaries and substantially all of our operations are conducted by our direct and indirect wholly owned subsidiaries. As a result, our ability to make payments on the notes will be dependent upon the receipt of sufficient funds from our subsidiaries. However, our various debt obligations are, and the notes will be, guaranteed, on a joint and several and full and unconditional basis, by most, but not all, of our direct and indirect wholly owned U.S. subsidiaries.

We cannot guarantee that there will be a trading market for the notes.

The notes are a new issue of securities for which no trading market currently exists. We do not intend to list the notes on any national or regional securities exchange or to seek approval for quotation through any automated quotation system. We cannot give any assurance that a trading market will exist in the future for the notes. Even if a market does develop, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for high yield securities and by changes in our financial performance or prospects or in the prospects for companies in our industry generally.

Use of proceeds

The net proceeds to us from the offering of the notes are estimated to be $295.2 million, after deducting discounts to the underwriters and estimated offering expenses. We intend to use the net proceeds for general corporate purposes, including funding a portion of the shareholder payout commitments we have made and possible future acquisitions and investments. Pending the use of proceeds as described above, we intend to invest the net proceeds of the offering in "Triple A" rated money market funds. We do not intend to repay or retire any indebtedness with the net proceeds from this offering. Assuming an interest rate of 8.0%, we would record annual interest expense associated with the notes of $24.6 million, or approximately $14.8 million after tax assuming a tax rate of 40%. An increase or decrease of 0.125% in the assumed annual interest rate would result in a corresponding increase or decrease in annual interest expense associated with the notes of approximately $0.4 million before taxes.

Description of the notes

The following description of the particular terms of the notes supplements and, to the extent inconsistent therewith, replaces the description of the general terms and provisions of debt securities set forth under "Description of our debt securities" in the accompanying prospectus, to which reference is hereby made. You can find the definitions of certain terms used in this description under the subheading "Certain definitions." Other terms are defined in the accompanying prospectus. Certain defined terms used in this description but not defined below under the subheading "Certain definitions" have the meanings assigned to them in the Indenture described below. In this description, the words "Company," "we," "us" and "our" refers only to Iron Mountain Incorporated and not to any of its subsidiaries.

General

The Company will issue the notes under an indenture dated as of the issue date of the notes, or the Base Indenture, as supplemented by a First Supplemental Indenture, also dated as of the issue date of the notes, or the Supplemental Indenture, among the Company, the guarantors and The Bank of New York Mellon Trust Company, N.A., as trustee, or the Trustee. For convenience, the Base Indenture, as supplemented by the Supplemental Indenture, is referred to as the "Indenture." The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act.

The following description is a summary of the material provisions of the Indenture. It does not restate the Indenture in its entirety. We urge you to read the Indenture because it, and not this description, defines your rights as a holder of the notes. If you would like more information on these provisions, review the copy of the Indenture that we have filed with the SEC. See "Incorporation by reference" and "Where you can find more information" in this prospectus supplement and in the accompanying prospectus for information about how to locate these documents. You may also review the Indenture at the Trustee's corporate trust office at BNY Mellon Corporate Trust, Corporate Finance Group, 525 William Penn Place, 38th Floor, Pittsburgh, PA 15259.

The Indenture permits the issuance of additional notes from time to time having identical terms and conditions to the notes offered in this offering. Any offering of additional notes is subject to the covenant described below under the caption "—Certain covenants—Incurrence of indebtedness and issuance of preferred stock." The notes and any additional notes subsequently issued under the Indenture will be treated as a single class for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase.

The notes will be general unsecured obligations of the Company and will mature on                         , 2019. The notes will be issued in registered form, without coupons, and in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes will be evidenced by a global note in book-entry form, except under the limited circumstances described below under "—Book-entry, delivery and form." The registered holder of a note, or Holder, will be treated as the owner of it for all purposes. Only registered Holders will have rights under the Indenture.

Table of Contents

The notes:

•

are general unsecured obligations of the Company;

•

are subordinated in right of payment to all existing and future Senior Debt of the Company;

•

are pari passu in right of payment with existing and any future senior subordinated Indebtedness of the Company; and

•

are unconditionally guaranteed by the guarantors.

The notes are guaranteed by the guarantors. Each subsidiary guarantee of the notes:

•

is a general unsecured obligation of the guarantor;

•

is subordinated in right of payment to all existing and future Senior Debt of the guarantor; and

•

is pari passu in right of payment with any existing and future senior subordinated Indebtedness of the guarantor.

Assuming we had completed this offering on June 30, 2011 and applied the net proceeds from this offering as described under "Use of proceeds," these notes and the subsidiary guarantees would have been subordinated to $592.6 million of the Company's and the subsidiary guarantors' Senior Debt and would have ranked equally with $2,295.5 million (including $6.1 million of net discounts) of the Company's and the subsidiary guarantors' other senior subordinated debt and trade payables (Canada Company is an obligor with respect to $181.1 million of this debt; Canada Company will not guarantee the notes offered hereby or the other senior subordinated debt). As indicated above and as discussed in detail below under the caption "—Subordination," payments on the notes and under the subsidiary guarantees will be subordinated to the payment of Senior Debt. The Indenture permits the Company and the guarantors to incur additional Senior Debt.

Not all of our subsidiaries will guarantee the notes. Substantially all of our direct and indirect wholly owned domestic subsidiaries will guarantee the notes. Canada Company, IME, their respective subsidiaries and the Company's other existing international subsidiaries will not be guarantors. In the event of a bankruptcy, liquidation or reorganization of any of these non-guarantor subsidiaries, these non-guarantor subsidiaries will pay the holders of their debts and their trade creditors before they will be able to distribute any of their assets to us. Our non-guarantor subsidiaries, including Canada Company, generated 33% of our consolidated revenues in the year ended December 31, 2010 and 35% of our consolidated revenues in the six month period ended June 30, 2011 and held 39% of our consolidated total assets as of June 30, 2011, in the latter case without reduction for the minority interests in certain of our international subsidiaries. See our consolidated financial statements incorporated by reference in this prospectus supplement from our quarterly report on Form 10-Q for the quarter ended June 30, 2011 and our current reports on Form 8-K filed September 19, 2011 for more detail about the division of our consolidated revenues and assets between the Company's guarantor and non-guarantor subsidiaries.

Interest

Interest on the notes will accrue at the rate of             % per annum and will be payable semi-annually in arrears on                           and                            , commencing on                  , 2012, to Holders of record on the immediately preceding                           and                            . Interest on the notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Methods of receiving payments on the notes

The notes will be payable both as to principal and interest at the office or agency of the Company maintained for such purpose within the City and State of New York or, at the option of the Company, payment of interest may be made by check mailed to the Holders of notes at their addresses set forth in the register of Holders of notes. Until otherwise designated by the Company, the Company's office or agency in New York will be the office of the Trustee maintained for such purpose.

Paying agent and registrar for the notes

The Trustee will initially act as paying agent and registrar. The Company may change the paying agent or registrar without prior notice to the Holders, and the Company or any of its Subsidiaries may act as paying agent or registrar.

Transfer and exchange

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

Subsidiary guarantees

The Company's payment obligations under the notes will be jointly and severally guaranteed pursuant to the subsidiary guarantees on an unsecured senior subordinated basis by all of the Company's Restricted Subsidiaries other than the Excluded Restricted Subsidiaries (as defined below). See "—Certain covenants—Additional subsidiary guarantees." Each subsidiary guarantee will be subordinated to the prior payment in full of all Senior Debt of each such subsidiary guarantor, which, assuming we had completed this offering on June 30, 2011 and applied the net proceeds from this offering as described under "Use of proceeds," would have been $592.6 million. Notwithstanding the subordination provisions contained in the Indenture, the obligations of a guarantor under its subsidiary guarantee will be unconditional, but will contain language intended to prevent that subsidiary guarantee from constituting a fraudulent conveyance under applicable law. See "Risk factors—Federal and state statutes could allow courts, under specific circumstances, to void guarantees and require holders of the notes to return payments received from guarantors."

S-22

Table of Contents

The subsidiary guarantee of a guarantor will be released under the circumstances described under "—Certain covenants—Additional subsidiary guarantees."

Subordination

The payment of principal of, premium, if any, and interest on the notes will be subordinated in right of payment, as set forth in the Indenture, to the prior payment in full in cash of all Obligations with respect to Senior Debt, whether outstanding on the date of the Indenture or thereafter incurred.

The holders of Senior Debt will be entitled to receive payment in full in cash of all Obligations due in respect of such Senior Debt (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Debt, whether or not allowed as a claim in such proceeding) before the Holders of notes will be entitled to receive any payment or distribution with respect to the notes. Until all Obligations with respect to Senior Debt are paid in full in cash, any payment or distribution to which the Holders of notes would be entitled shall be made to the holders of Senior Debt, upon any payment or distribution to creditors of the Company or any guarantor:

(1)   in a liquidation or dissolution of the Company or such guarantor; or

(2)   in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or any guarantor or its property; or

(3)   in an assignment for the benefit of creditors; or

(4)   in any marshaling of the assets and liabilities of the Company or any guarantor.

Neither the Company nor any guarantor may make any payment or distribution upon or in respect of the notes, including, without limitation, by way of set-off or otherwise, or redeem (or make a deposit in redemption of), defease or acquire any of the notes for cash, properties or securities if:

(1)   a default in the payment of any Obligation in respect of any Senior Debt occurs and is continuing; or

(2)   any other default (or any event that, after notice or passage of time would become a default), or a Non-Monetary Default, occurs and is continuing with respect to Senior Debt and the Trustee receives a notice of such default, or a Payment Blockage Notice, from the holders (or the agent or representative of such holders) of any Designated Senior Debt.

Payments on the notes may and shall be resumed:

(1)   in the case of a payment default, on the date on which such default is cured or waived; and

(2)   in the case of a Non-Monetary Default, on the earlier of the date on which such Non-Monetary Default is cured or waived or 179 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Senior Debt has been accelerated.

S-23

---

Table of Contents

Any number of Payment Blockage Notices may be given; provided, however, that:

(1)   not more than one Payment Blockage Notice may be commenced during any period of 360 consecutive days; and

(2)   any Non-Monetary Default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee (to the extent the holder of Designated Senior Debt, or such trustee or agent, giving such Payment Blockage Notice had knowledge of the same) shall not be the basis for a subsequent Payment Blockage Notice, unless such default has been cured or waived for a period of not less than 90 consecutive days.

The Company must promptly notify holders of Senior Debt if payment of the notes is accelerated because of an Event of Default (as described below).

As a result of the subordination provisions described above, in the event of a liquidation or insolvency, Holders of notes may recover less ratably than creditors of the Company who are holders of Senior Debt. After giving effect to the offering of the notes and the use of the net proceeds as described under "Use of proceeds", the principal amount of Senior Debt of the Company and the guarantors outstanding at June 30, 2011 would have been $592.6 million. The Indenture will not limit the amount of additional Indebtedness, including Senior Debt, that the Company and its Restricted Subsidiaries can incur if certain financial tests are met. See "—Certain covenants—Incurrence of indebtedness and issuance of preferred stock."

Optional redemption

Prior to                         , 2015, the notes will be subject to redemption at any time at the option of the Company, in whole or in part, upon not less than 10 nor more than 60 days' notice, at the Make-Whole Price, plus accrued and unpaid interest to, but excluding, the applicable redemption date. On and after                         , 2015, the notes will be subject to redemption at any time at the option of the Company, in whole or in part, upon not less than 10 nor more than 60 days' notice, at the redemption price (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest to, but excluding, the applicable redemption date, if redeemed during the 12-month period beginning on                          of the years indicated below:

Notwithstanding the foregoing, at any time prior to                         , 2014, the Company may on any one or more occasions redeem the notes at a redemption price of         % of the principal amount thereof, plus accrued and unpaid interest to the redemption date, with the net cash proceeds of one or more Qualified Equity Offerings; provided that:

(1)   at least $195.0 million in the aggregate principal amount of the notes (including any additional notes subsequently issued as part of the same class) issued under the Indenture remains outstanding immediately after the occurrence of such redemption (excluding notes held by the Company or any of its subsidiaries); and

S-24

Table of Contents

(2)   the redemption occurs within six months of the date of the closing of any such Qualified Equity Offering.

Mandatory redemption

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

Repurchase at the option of holders

Change of control.    Upon the occurrence of a Change of Control, each Holder of notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder's notes pursuant to the offer described below, or the Change of Control Offer, at an offer price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest to, but excluding, the date of repurchase, or the Change of Control Payment.

Within 30 calendar days following any Change of Control, the Company will mail a notice to each Holder stating:

(1)   that the Change of Control Offer is being made pursuant to the covenant entitled "Change of control" and that all notes tendered will be accepted for payment;

(2)   the purchase price and the purchase date, which will be no earlier than 30 calendar days nor later than 60 calendar days from the date such notice is mailed, or the Change of Control Payment Date;

(3)   that any note not tendered will continue to accrue interest;

(4)   that, unless the Company defaults in the payment of the Change of Control Payment, all notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on and after the Change of Control Payment Date;

(5)   that Holders electing to have any notes purchased pursuant to a Change of Control Offer will be required to surrender the notes, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the notes completed, to the paying agent at the address specified in such notice prior to the close of business on the fifth Business Day preceding the Change of Control Payment Date;

(6)   that Holders will be entitled to withdraw their election if the paying agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, facsimile transmission or letter setting forth the name of the Holder, the principal amount of notes delivered for purchase, and a statement that such Holder is withdrawing its election to have such notes purchased; and

(7)   that Holders whose notes are being purchased only in part will be issued new notes equal in principal amount to the unpurchased portion of the notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder, to the extent such laws and regulations

S-25

---

Table of Contents

are applicable to the repurchase of the notes in connection with a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the Indenture by virtue of such conflict.

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

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

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

(3)   deliver or cause to be delivered to the Trustee the notes so accepted together with an Officers' Certificate stating the notes or portions thereof tendered to the Company.

The paying agent will promptly mail to each Holder of notes so accepted the Change of Control Payment for such notes, and the Trustee will promptly authenticate and mail to each Holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each such new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

Except as described above with respect to a Change of Control, the Indenture does not contain provisions that permit the Holders of the notes to require that the Company repurchase or redeem the notes in the event of a takeover, recapitalization or similar restructuring, nor does it contain any other "event risk" protections for Holders of the notes.

Although the Change of Control provision may not be waived by the Company, and may be waived by the Trustee only in accordance with the provisions of the Indenture, there can be no assurance that any particular transaction (including a highly leveraged transaction) cannot be structured or effected in a manner not constituting a Change of Control.

The Credit Agreement currently limits the right of the Company to purchase any notes prior to their scheduled maturity and also provides that a Change of Control with respect to the Company is a default thereunder. Any future credit agreements or other agreements relating to Senior Debt to which the Company becomes a party may contain similar restrictions and provisions. In the event a Change of Control occurs at a time when the Company is prohibited from purchasing notes, the Company could seek a waiver of the default under the Credit Agreement, the consent of its lenders to the purchase of notes or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such a waiver and consent or repay such borrowings, the Company would remain prohibited from purchasing notes and be in default under the Credit Agreement. In such case, the Company's failure to purchase tendered notes would, in turn, constitute an Event of Default under the Indenture. In such circumstances, the subordination provisions in the Indenture would likely restrict payments to the Holders of notes.

The Company 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 made by the Company and purchases all notes properly tendered and

not withdrawn under the Change of Control Offer. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of "all or substantially all" of the properties or assets of the Company. Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of notes to require the Company to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Company to another Person or group may be uncertain.

Asset sales.    The Company will not, and will not permit any of its Restricted Subsidiaries to:

(i) sell, lease, convey or otherwise dispose of any assets (including by way of a Sale and Leaseback Transaction, but excluding a Qualifying Sale and Leaseback Transaction) other than sales of inventory in the ordinary course of business (provided that the sale, lease, conveyance or other disposition of all or substantially all of the assets of the Company will be governed by the provisions of the Indenture described above under the caption "Change of control" and/or the provisions described below under the caption "Certain covenants—Merger, consolidation or sale of assets" and not by the provisions of this covenant); or

(ii) issue or sell Equity Interests of any of its Restricted Subsidiaries that, in the case of either clause (1) or (2) above, whether in a single transaction or a series of related transactions:

(A)  have a fair market value in excess of $2.0 million; or

(B)   result in Net Proceeds in excess of $2.0 million, each of the foregoing, an Asset Sale, unless (x) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (evidenced by an Officers' Certificate delivered to the Trustee, and for Asset Sales having a fair market value or resulting in net proceeds in excess of $10.0 million, evidenced by a resolution of the Company's board of directors set forth in an Officers' Certificate delivered to the Trustee) of the assets sold or otherwise disposed of and (y) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash, Cash Equivalents, like-kind assets or other assets used in or useful in the Company's business (in each case as determined in good faith by the Company, evidenced by a resolution of the Company's board of directors and certified by an Officers' Certificate delivered to the Trustee);

provided, however, that the amount of:

(A)  any liabilities (as shown on the Company's or such Restricted Subsidiary's most recent balance sheet or in the notes thereto) of the Company or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the notes or any subsidiary guarantee) that are assumed by the transferee of any such assets; and

(B)   any notes or other obligations received by the Company or such Restricted Subsidiary from such transferee that are immediately converted by the Company or such Restricted Subsidiary into cash (to the extent of the cash received) or Cash Equivalents,

S-27

Table of Contents

shall be deemed to be cash for purposes of this provision; and provided, further, that the 75% limitation referred to in the foregoing clause (ii) (y) shall not apply to any Asset Sale in which the cash portion of the consideration received therefrom is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation. For the avoidance of doubt, a disposition that constitutes a Restricted Payment will be governed by the provisions of the Indenture described below under the covenant entitled "Restricted payments" and not by the provisions of this covenant.

A transfer of assets or issuance of Equity Interests by the Company to a Wholly Owned Restricted Subsidiary or by a Wholly Owned Restricted Subsidiary to the Company or to another Wholly Owned Restricted Subsidiary will not be deemed to be an Asset Sale.

Within 360 days of any Asset Sale, the Company may, at its option, apply an amount equal to the Net Proceeds from such Asset Sale either:

(1)   to permanently reduce Senior Debt; or

(2)   to an investment in a Restricted Subsidiary or in another business or capital expenditure or other long-term/tangible assets, in each case, in the same line of business as the Company or any of its Restricted Subsidiaries was engaged on the date of the Indenture or in businesses similar or reasonably related thereto.

Pending the final application of any such Net Proceeds, the Company may temporarily reduce Senior Bank Debt or otherwise invest such Net Proceeds in any manner that is not prohibited by the Indenture. Any Net Proceeds from such Asset Sale that are not applied or invested as provided in the first sentence of this paragraph will be deemed to constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall make an offer to all Holders of the notes, all holders of the 7¹/4% notes due 2014, the 6⁵/8% notes due 2016, the 7¹/2% notes due 2017, the 8³/4% notes due 2018, the 8% notes due 2018, the 6³/4% notes due 2018, the 8% notes due 2020, and the 8³/8% notes due 2021, and the holders of any future Indebtedness ranking pari passu with the notes, which Indebtedness contains similar provisions requiring the Company to repurchase such Indebtedness, or an Asset Sale Offer, to purchase the maximum principal amount of notes and such other Indebtedness that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of notes and other pari passu Indebtedness (including the 7¹/4% notes due 2014, the 6⁵/8% notes due 2016, the 7¹/2% notes due 2017, the 8³/4% notes due 2018, the 8% notes due 2018, the 6³/4% notes due 2018, the 8% notes due 2020 and the 8³/8% notes due 2021) tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes. If the aggregate principal amount of notes and such other Indebtedness surrendered by Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the notes and such other Indebtedness to be purchased on a pro rata basis. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero.

Table of Contents

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of the Indenture by virtue of such conflict. Existing agreements governing the Company's outstanding Senior Debt generally restrict the Company from purchasing any notes prior to scheduled maturity and also provide that certain asset sale events with respect to the Company would constitute a default under these agreements. Any future credit agreements or other agreements relating to Senior Debt to which the Company becomes a party may contain similar restrictions and provisions. In the event an Asset Sale occurs at a time when the Company is prohibited from purchasing notes, the Company could seek the consent of its senior lenders to the purchase of notes or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such a consent or repay such borrowings, the Company would remain prohibited from purchasing notes. In such case, the Company's failure to purchase tendered notes would constitute an Event of Default under the Indenture which would, in turn, constitute a default under such Senior Debt. In such circumstances, the subordination provisions in the Indenture would likely restrict payments to the Holders of notes.

Selection and notice

If less than all of the notes are to be redeemed at any time, the Trustee will select notes for redemption on a pro rata basis (or, in the case of notes issued in global form as discussed under "—Book-entry, delivery and form," based on a method that most nearly approximates a pro rata selection as the Trustee deems fair and appropriate) unless otherwise required by law or applicable stock exchange or depositary requirements.

No notes of $2,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 10 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 such note shall state the portion of the principal amount thereof to be redeemed. A new note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original note. On and after the redemption date, interest will cease to accrue on notes or portions thereof called for redemption.

Certain covenants

Changes in covenants when notes rated investment grade.    If on any date following the date of the indenture:

(1)   at least two of the following events occurs:

(i)    the notes are rated Baa3 or better by Moody's Investors Service,

(ii)   the notes are rated BBB- or better by Standard & Poor's Rating Group, a division of McGraw Hill, Inc., or

S-29

Table of Contents

(iii)  the notes are rated BBB- or better by Fitch Ratings Inc.,

(or, if any such entity ceases to rate the notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other "nationally recognized statistical rating organization" within the meaning of Section 3(a)(62) of the Exchange Act selected by the Company as a replacement agency); and

(2)   no Default or Event of Default shall have occurred and be continuing,

then, beginning on that day and continuing at all times thereafter regardless of any subsequent changes in the rating of the notes, the covenants described under the following captions in this prospectus supplement will no longer be applicable to the notes:

(1)   "—Repurchase at the option of holders—Asset sales";

(2)   "—Restricted payments";

(3)   "—Incurrence of indebtedness and issuance of preferred stock";

(4)   "—Dividend and other payment restrictions affecting restricted subsidiaries";

(5)   "—Transactions with affiliates";

(6)   clause (3) of the covenant described below under the caption "—Additional subsidiary guarantees";

(7)   "—Unrestricted subsidiaries";

(8)   clause (4) of the covenant described below under the caption "—Merger, consolidation or sale of assets"; and

(9)   clause (2) of the covenant described below under the caption "—Limitation on sale and leaseback transactions."

There can be no assurance that the notes will ever achieve an investment grade rating or that any such rating will be maintained.

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

(1)   declare or pay any dividend or make any distribution on account of the Company's or any of its Restricted Subsidiaries' Equity Interests (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or such Restricted Subsidiary or dividends or distributions payable to the Company or any Restricted Subsidiary);

(2)   purchase, redeem or otherwise acquire or retire for value any Equity Interests of the Company or any Restricted Subsidiary or other Affiliate of the Company (other than any such Equity Interests owned by the Company or any Restricted Subsidiary);

(3)   purchase, redeem or otherwise acquire or retire prior to scheduled maturity for value any Indebtedness that is subordinated in right of payment to the notes; or

S-30

Table of Contents

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

unless, at the time of such Restricted Payment:

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

(ii)   the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the test set forth in the first paragraph of the covenant entitled "Incurrence of indebtedness and issuance of preferred stock"; and

(iii)  such Restricted Payment, together with the aggregate of all other Restricted Payments made by the Company and its Restricted Subsidiaries after October 1, 1996 is less than (x) the cumulative EBITDA of the Company, minus 1.75 times the cumulative Consolidated Interest Expense of the Company, in each case for the period (taken as one accounting period) from June 30, 1996, to the end of the Company's most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment, plus (y) the aggregate net Equity Proceeds received by the Company from the issuance or sale since the date of the 1996 Indenture of Equity Interests of the Company or of debt securities of the Company that have been converted into such Equity Interests (other than Equity Interests or convertible debt securities sold to a Restricted Subsidiary of the Company and other than Disqualified Stock or debt securities that have been converted into Disqualified Stock), plus (z) $2.0 million.

As of June 30, 2011, the amount that would have been available to the Company for Restricted Payments pursuant to this clause (iii) would have been approximately $3.5 billion. Under the indentures for the Company's outstanding 6⁵/8% notes due 2016, the amount of Restricted Payments that would have been available to the Company under the comparable Restricted Payment covenant was approximately $2.3 billion. Under the indenture for the outstanding 7¹/4% notes due 2014, the amount of Restricted Payments that would have been available to the Company under the comparable Restricted Covenant was approximately $2.6 billion. Under the indentures for the outstanding 7¹/2% notes due 2017, the 8³/4% notes due 2018, the 8% notes due 2018, the 6³/4% notes due 2018, the 8% notes due 2020, and the 8³/8% notes due 2021, the amount of Restricted Payments that would have been available to the Company under the comparable Restricted Payment covenant was approximately $3.5 billion. The Company has similar (and more restrictive) covenants in its Credit Agreement. The amount of Restricted Payments that the Company could make without violating these covenants is substantially less than the amount that would be permitted under the Indenture.

The foregoing provisions will not prohibit:

(1)   the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of the Indenture;

(2)   the redemption, repurchase, retirement or other acquisition or retirement for value of any Equity Interests of the Company in exchange for, or with the net cash proceeds of, the

S-31

Table of Contents

substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of other Equity Interests of the Company (other than any Disqualified Stock);

(3)   the defeasance, redemption, repurchase, retirement or other acquisition or retirement for value of Indebtedness that is subordinated in right of payment to the notes in exchange for, or with the net cash proceeds of, a substantially concurrent issuance and sale (other than to a Restricted Subsidiary of the Company) of Equity Interests of the Company (other than Disqualified Stock);

(4)   the defeasance, redemption, repurchase, retirement or other acquisition or retirement for value of Indebtedness that is subordinated in right of payment to the notes in exchange for, or with the net cash proceeds of, a substantially concurrent issue and sale (other than to the Company or any of its Restricted Subsidiaries) of Refinancing Indebtedness;

(5)   the repurchase of any Indebtedness subordinated in right of payment to the notes at a purchase price not greater than 101% of the principal amount of such Indebtedness in the event of a Change of Control in accordance with provisions similar to the "Change of control" covenant, provided that prior to or contemporaneously with such repurchase the Company has made the Change of Control Offer as provided in such covenant with respect to the notes and has repurchased all notes validly tendered for payment in connection with such Change of Control Offer; and

(6)   additional payments to current or former employees or directors of the Company for repurchases of stock, stock options or other equity interests, provided that the aggregate amount of all such payments under this clause (6) does not exceed $0.5 million in any year and $2.0 million in the aggregate.

The Restricted Payments described in clauses (2), (3), (5) and (6) of the immediately preceding paragraph will be Restricted Payments that will be permitted to be taken in accordance with such paragraph but will reduce the amount that would otherwise be available for Restricted Payments under clause (iii) of the first paragraph of this section, and the Restricted Payments described in clauses (1) and (4) of the immediately preceding paragraph will be Restricted Payments that will be permitted to be taken in accordance with such paragraph and will not reduce the amount that would otherwise be available for Restricted Payments under clause (iii) of the first paragraph of this section.

If an Investment results in the making of a Restricted Payment, the aggregate amount of all Restricted Payments deemed to have been made as calculated under the foregoing provision will be reduced by the amount of any net reduction in such Investment (resulting from the payment of interest or dividends, loan repayment, transfer of assets or otherwise) to the extent such net reduction is not included in the Company's EBITDA; provided, however, that the total amount by which the aggregate amount of all Restricted Payments may be reduced may not exceed the lesser of (a) the cash proceeds received by the Company and its Restricted Subsidiaries in connection with such net reduction and (b) the initial amount of such Investment. In addition, for the avoidance of doubt and to avoid double counting, if an Investment results in the making of a Restricted Payment, then the subsequent assignment, contribution, distribution or other transfer of such Investment by the Company or any Restricted Subsidiary of the Company to any Excluded Restricted Subsidiary or Unrestricted Subsidiary shall not be considered a new Investment or Restricted Payment and shall not

S-32

further reduce the amount that would otherwise be available for Restricted Payments under clause (iii) of the first paragraph of this section.

If the aggregate amount of all Restricted Payments calculated under the foregoing provision includes an Investment in an Unrestricted Subsidiary or other Person that thereafter becomes a Restricted Subsidiary, such Investment will no longer be counted as a Restricted Payment for purposes of calculating the aggregate amount of Restricted Payments.

For the purpose of making any Restricted Payment calculations under the Indenture:

(1)   Investments will include the fair market value of the net assets of any Restricted Subsidiary at the time that such Restricted Subsidiary is designated an Unrestricted Subsidiary and will exclude the fair market value of the net assets of any Unrestricted Subsidiary that is designated as a Restricted Subsidiary, in each case with fair market value determined by the Company's board of directors in good faith and, for the avoidance of doubt, such inclusions and exclusions will not be limited by the amount of any Investment or aggregate Investments;

(2)   any asset or property transferred to or from an Unrestricted Subsidiary will be valued at fair market value at the time of such transfer, provided that, in each case the fair market value of an asset or property is as determined by the Company's board of directors in good faith and, for the avoidance of doubt, the fair market value (as so determined) of such asset or property shall be subtracted from (in the case of a transfer to an Unrestricted Subsidiary) or added to (in the case of a transfer from an Unrestricted Subsidiary) the calculation under clause (iii) of the first paragraph of this section; and

(3)   subject to the foregoing, the amount of any Restricted Payment, if other than cash, will be determined by the Company's board of directors, whose good faith determination will be conclusive.

The Company's board of directors may designate a Restricted Subsidiary to be an Unrestricted Subsidiary in compliance with the covenant entitled "Unrestricted subsidiaries." Upon such designation, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments made at the time of such designation and will reduce the amount available for Restricted Payments under the first paragraph of this covenant. Such designation will only be permitted if such Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Incurrence of indebtedness and issuance of preferred stock.    The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guaranty or otherwise become directly or indirectly liable with respect to, or, collectively, incur, any Indebtedness (including Acquired Debt) and the Company will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness and may permit a Restricted Subsidiary to incur Indebtedness if, at the time of such incurrence and after giving effect thereto, the Leverage Ratio would be less than 6.5 to 1.0.

The foregoing limitations will not apply to:

(1)   the incurrence by the Company or any Restricted Subsidiary of Senior Bank Debt in an aggregate amount not to exceed $790.0 million at any one time outstanding;

S-33

---

Table of Contents

(2)   the issuance by the Restricted Subsidiaries of subsidiary guarantees;

(3)   the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness;

(4)   the issuance by the Company of the notes;

(5)   the incurrence by the Company and its Restricted Subsidiaries of Capital Lease Obligations and/or additional Indebtedness constituting purchase money obligations up to an aggregate of $5.0 million at any one time outstanding, provided that the Liens securing such Indebtedness constitute Permitted Liens;

(6)   the incurrence of Indebtedness between (i) the Company and its Restricted Subsidiaries and (ii) the Restricted Subsidiaries;

(7)   Hedging Obligations that are incurred in the ordinary course of business, provided, in the case of Hedging Obligations with respect to Indebtedness, that such Indebtedness is permitted to be outstanding by the terms of the Indenture;

(8)   the incurrence by the Company and its Restricted Subsidiaries of Indebtedness arising out of letters of credit, performance bonds, surety bonds and bankers' acceptances incurred in the ordinary course of business up to an aggregate of $5.0 million at any one time outstanding;

(9)   the incurrence by the Company and its Restricted Subsidiaries of Indebtedness consisting of guarantees, indemnities or obligations in respect of purchase price adjustments in connection with the acquisition or disposition of assets, including, without limitation, shares of Capital Stock;

(10) the incurrence by the Company and its Restricted Subsidiaries of Refinancing Indebtedness issued in exchange for, or the proceeds of which are used to repay, redeem, defease, extend, refinance, renew, replace or refund, Indebtedness referred to in clauses (2) through (5) above, and this clause (10) or that was otherwise permitted to be incurred pursuant to the test set forth in the first paragraph of this covenant; and

(11) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (11), not to exceed $50.0 million.

There are additional limitations on the ability of some Excluded Restricted Subsidiaries to incur Indebtedness as provided in the covenant described under the caption "Dividend and other payment restrictions affecting restricted subsidiaries."

For purposes of determining compliance with this "Incurrence of indebtedness and issuance of preferred stock" covenant, for the avoidance of doubt, in the event that an item of Indebtedness meets the criteria of more than one of the categories of permitted debt described in clauses (1) through (11) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant. The accrual of interest or preferred stock dividends, the accretion or amortization of original issue discount, the payment

Table of Contents

of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this covenant; provided, in each such case, that the amount thereof is included in the Consolidated Interest Expense of the Company as accrued. For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company or any of its Restricted Subsidiaries may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

The amount of any Indebtedness outstanding as of any date will be:

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

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

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

(i)    the fair market value of such assets at the date of determination; and

(ii)   the amount of the Indebtedness of the other Person.

Liens.    Neither the Company nor any of its Restricted Subsidiaries may directly or indirectly create, incur, assume or suffer to exist any Lien (other than a Permitted Lien) upon any property or assets now owned or hereafter acquired, or any income, profits or proceeds therefrom, or assign or otherwise convey any right to receive income therefrom, unless (a) in the case of any Lien securing any Indebtedness that is subordinate to the notes, the notes are secured by a Lien on such property, assets or proceeds that is senior in priority to such Lien and (b) in the case of any other Lien, the notes are equally and ratably secured with the obligation or liability secured by such Lien.

Dividend and other payment restrictions affecting restricted subsidiaries.    The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1)   (i) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (A) on its Capital Stock or (B) with respect to any other interest or participation in, or measured by, its profits, or (ii) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries;

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

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

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

(1)   Existing Indebtedness;

(2)   the Credit Agreement as in effect as of the date of the Indenture, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancing thereof, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive in the aggregate with respect to such dividend and other payment restrictions than those contained in the Credit Agreement as in effect on the date of the Indenture;

(3)   the Indenture and the notes;

(4)   applicable law, including, for the avoidance of doubt, any applicable rule, regulation or order;

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

(6)   customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices;

(7)   restrictions on the transfer of property subject to purchase money obligations or Capital Lease Obligations otherwise permitted by clause (5) of the covenant entitled "Incurrence of indebtedness and issuance of preferred stock";

(8)   permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Refinancing Indebtedness are no more restrictive in the aggregate than those contained in the agreements governing the Indebtedness being refinanced;

(9)   any agreement or instrument governing Indebtedness of an Excluded Restricted Subsidiary, provided that (i) at the time such agreement or instrument is entered into, such Excluded Restricted Subsidiary and its Restricted Subsidiaries have a Leverage Ratio of less than 6.5 to 1.0 and (ii) neither such Excluded Restricted Subsidiary nor any of its Restricted Subsidiaries shall, directly or indirectly, incur any Indebtedness (including Acquired Debt) unless at the time of such incurrence and after giving effect thereto, the Leverage Ratio for such Excluded Restricted Subsidiary and its Restricted Subsidiaries would be less than 6.5 to 1.0. For purposes of determining the Leverage Ratio under this clause (9) only, all references to the "Company" and its "Restricted Subsidiaries" or similar references in the definition of "Leverage Ratio" and other defined terms necessary to determine the Leverage Ratio shall be deemed to refer to such Excluded Restricted Subsidiary and its Restricted Subsidiaries, respectively; or

(10) agreements governing other Indebtedness permitted to be incurred under the provisions of the covenant described above under the caption "—Incurrence of indebtedness and issuance of preferred stock" and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the restrictions therein are not materially more restrictive, taken as a whole, than those contained in the Indenture, the notes and the subsidiary guarantees.

Merger, consolidation or sale of assets.    The Company may not consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another Person unless:

(1)   either: (i) the Company is the surviving corporation or (ii) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia (provided that, if such entity is not a corporation, a co-obligor of the notes is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia);

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

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

(4)   the Company or any Person formed by or surviving any such consolidation or merger, or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made, will, at the time of such transaction and after giving pro forma effect thereto, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the test set forth in the first paragraph of the covenant entitled "Incurrence of indebtedness and issuance of preferred stock."

This "Merger, consolidation or sale of assets" covenant will not apply to any sale, assignment, transfer, conveyance, lease or other disposition of assets between or among the Company and its Restricted Subsidiaries. Clauses (3) and (4) of the first paragraph of this covenant will not apply to any merger or consolidation of the Company (i) with or into one of its Restricted Subsidiaries for any purpose or (ii) with or into an Affiliate solely for the purpose of reincorporating the Company in another jurisdiction in the United States.

Transactions with affiliates.    The Company will not, and will not permit any of its Restricted Subsidiaries to, sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into any contract, agreement, understanding,

loan, advance or guarantee with, or for the benefit of, any Affiliate, each of the foregoing, an Affiliate Transaction, unless:

(1)   such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a non-Affiliated Person; and

(2)   the Company delivers to the Trustee:

(i)    with respect to any Affiliate Transaction involving aggregate payments in excess of $10.0 million, a resolution of the Company's board of directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (1) above and such Affiliate Transaction is approved by a majority of the disinterested members of the Company's board of directors; and

(ii)   with respect to any Affiliate Transaction involving aggregate payments in excess of $25.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary from a financial point of view issued by an investment banking, appraisal or accounting firm of national standing.

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

(1)   any employment agreement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with the past practice of the Company or such Restricted Subsidiary;

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

(3)   transactions permitted by the provisions of the Indenture described above under the covenant entitled "Restricted payments;" and

(4)   the grant of stock, stock options or other equity interests to employees and directors of the Company and any Restricted Subsidiary in accordance with duly adopted Company stock grant, stock option and similar plans.

The provisions set forth in clause (2) above shall not apply to sales of inventory by the Company or any Restricted Subsidiary to any Affiliate in the ordinary course of business. The provisions of clause (2) (ii) above shall not apply to loans or advances to the Company or any Restricted Subsidiary from, or equity investments in the Company or any Restricted Subsidiary by, any Affiliate to the extent permitted by the provisions of the Indenture described above under the covenant entitled "Incurrence of indebtedness and issuance of preferred stock."

Certain senior subordinated debt.    The Company will not incur any Indebtedness that is subordinated or junior in right of payment to any Senior Debt of the Company and senior in any respect in right of payment to the notes. The Company will not permit any Restricted Subsidiary to incur any Indebtedness that is subordinated or junior in right of payment to its Senior Debt and senior in any respect in right of payment to its subsidiary guarantee.

Additional subsidiary guarantees.    If any entity (other than an Excluded Restricted Subsidiary) shall become a Restricted Subsidiary after the date of the Indenture, then such Restricted

S-38

Table of Contents

Subsidiary shall execute a subsidiary guarantee and deliver an opinion of counsel with respect thereto, in accordance with the terms of the Indenture.

No Restricted Subsidiary (including any Excluded Restricted Subsidiary) may consolidate (or, for the avoidance of doubt, amalgamate) with or merge with or into (whether or not such Restricted Subsidiary is the surviving Person), another Person (other than the Company) whether or not affiliated with such Restricted Subsidiary unless:

(1)   subject to the provisions of the following paragraph, the Person formed by or surviving any such consolidation (or amalgamation) or merger (if other than such Restricted Subsidiary) assumes all the obligations of such Restricted Subsidiary under its subsidiary guarantee (except in the case of an Excluded Restricted Subsidiary) pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee;

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

(3)   such Restricted Subsidiary, or any Person formed by or surviving any such consolidation (or amalgamation) or merger, would be permitted to incur, immediately after giving effect to such transaction, at least $1.00 of additional Indebtedness pursuant to the test set forth in the first paragraph of the covenant entitled "Incurrence of indebtedness and issuance of preferred stock."

In the event of:

(1)   a sale or other disposition of all of the assets of any Restricted Subsidiary, by way of merger, consolidation (or amalgamation) or otherwise;

(2)   a sale or other disposition of all of the capital stock of any Restricted Subsidiary; or

(3)   the designation of a Restricted Subsidiary as an Unrestricted Subsidiary in accordance with the terms of the covenant entitled "Unrestricted subsidiaries,"

then such Restricted Subsidiary (in the event of a sale or other disposition, by way of such a merger, consolidation (or amalgamation) or otherwise, of all of the capital stock of such Restricted Subsidiary or in the event of the designation of such Restricted Subsidiary as an Unrestricted Subsidiary) or the Person acquiring the property (in the event of a sale or other disposition of all of the assets of such Restricted Subsidiary) will be released and relieved of any obligations under its subsidiary guarantee; provided that the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of the Indenture. See "—Repurchase at the option of holders—Asset sales."

Unrestricted subsidiaries.    The Company's board of directors may designate any Subsidiary (including any Restricted Subsidiary or any newly acquired or newly formed Subsidiary) to be an Unrestricted Subsidiary so long as:

(1)   neither the Company nor any Restricted Subsidiary is directly or indirectly liable for any Indebtedness of such Subsidiary;

(2)   no default with respect to any Indebtedness of such Subsidiary would permit (upon notice, lapse of time or otherwise) any holder of any other Indebtedness of the Company or any

S-39

---

Table of Contents

Restricted Subsidiary to declare a default on such other Indebtedness or cause the payment thereof to be accelerated or payable prior to its stated maturity;

(3)   any Investment in such Subsidiary deemed to be made as a result of designating such Subsidiary an Unrestricted Subsidiary will not violate the provisions of the covenant entitled "Restricted payments;"

(4)   neither the Company nor any Restricted Subsidiary has a contract, agreement, arrangement, understanding or obligation of any kind, whether written or oral, with such Subsidiary other than (i) those that might be obtained at the time from Persons who are not Affiliates of the Company or (ii) administrative, tax sharing and other ordinary course contracts, agreements, arrangements and understandings or obligations entered into in the ordinary course of business; and

(5)   neither the Company nor any Restricted Subsidiary has any obligation to subscribe for additional shares of Capital Stock or other Equity Interests in such Subsidiary, or to maintain or preserve such Subsidiary's financial condition or to cause such Subsidiary to achieve certain levels of operating results other than as permitted under the covenant entitled "Restricted payments."

Notwithstanding the foregoing, the Company may not designate as an Unrestricted Subsidiary any Subsidiary which, on April 26, 1999, was a Significant Subsidiary, and may not sell, transfer or otherwise dispose of any properties or assets of any such Significant Subsidiary to an Unrestricted Subsidiary, other than in the ordinary course of business, in each case other than Iron Mountain Global, Inc. and its Subsidiaries (including without limitation IME and its Subsidiaries). For the avoidance of doubt, the provisions of this covenant shall not limit or restrict the ability of any Restricted Subsidiary to sell, transfer or otherwise dispose of any properties or assets to any other Subsidiary, including any Unrestricted Subsidiary, to the extent such sale, transfer or other disposition is permitted by the provisions of the Indenture described above under the covenants entitled "—Offer to repurchase notes—Asset sales" or "—Transactions with affiliates."

The Company's board of directors may designate any Unrestricted Subsidiary as a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if:

(1)   such Indebtedness is permitted under the "Incurrence of indebtedness and issuance of preferred stock" covenant; and

(2)   no Default or Event of Default would occur as a result of such designation.

Limitation on sale and leaseback transactions.    The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction unless:

(1)   the consideration received in such Sale and Leaseback Transaction is at least equal to the fair market value of the property sold, as determined by a resolution of the board of directors of the Company; and

S-40

---

Table of Contents

(2)   the Company or such Restricted Subsidiary could incur the Attributable Indebtedness in respect of such Sale and Leaseback Transaction in compliance with the covenant entitled "Incurrence of indebtedness and issuance of preferred stock."

Reports.    Whether or not required by the rules and regulations of the SEC, so long as any notes are outstanding, the Company will furnish to the Holders of notes:

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

(2)   all financial information that would be required to be included in a Form 8-K filed with the SEC if the Company were required to file such reports.

In addition, whether or not required by the rules and regulations of the SEC, the Company will file a copy of all such information and reports with the SEC for public availability (unless the SEC will not accept such a filing) and make such information available to investors who request it in writing.

Notwithstanding the foregoing, if at any time the notes are guaranteed by any direct or indirect parent company of the Company, the indenture will permit the Company to satisfy its obligations under this covenant with respect to financial information relating to the Company by furnishing financial information relating to such direct or indirect parent company; provided, however, that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such direct or indirect parent company and any of its Subsidiaries other than the Company and its Subsidiaries, on the one hand, and the information relating to the Company, the Guarantors and the other Subsidiaries of the Company on a standalone basis, on the other hand.

Events of default and remedies

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

(1)   default for 30 days in the payment when due of interest on the notes (whether or not prohibited by the subordination provisions of the Indenture);

(2)   default in payment when due of the principal of or premium, if any, on the notes (whether or not prohibited by the subordination provisions of the Indenture);

(3)   failure by the Company to comply with the provisions described under "—Repurchase at the option of holders—Change of control";

(4)   failure by the Company or any guarantor for 60 days after written notice from the Trustee or Holders of not less than 25% of the aggregate principal amount of the notes outstanding to comply with any of its other agreements in the Indenture, notes or the subsidiary guarantees;

(5)   default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the

S-41

---

Table of Contents

Company or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee exists on the date of the Indenture or is created thereafter, if:

(i)    such default results in the acceleration of such Indebtedness prior to its express maturity or shall constitute a default in the payment of such Indebtedness at final maturity of such Indebtedness; and

(ii)   the principal amount of any such Indebtedness that has been accelerated or not paid at maturity, when added to the aggregate principal amount of all other such Indebtedness that has been accelerated or not paid at maturity, exceeds $50.0 million;

(6)   failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $50.0 million, which judgments remain unpaid, undischarged or unstayed for a period of 60 days;

(7)   certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted Subsidiaries that are Significant Subsidiaries; and

(8)   except as permitted by the Indenture or the subsidiary guarantees, any subsidiary guarantee issued by a Restricted Subsidiary shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or any Restricted Subsidiary or any Person acting on behalf of any Restricted Subsidiary shall deny or disaffirm in writing its obligations under its subsidiary guarantee.

If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding notes may declare all the notes to be due and payable immediately; provided, however, that if any Obligation with respect to Senior Bank Debt is outstanding pursuant to the Credit Agreement upon a declaration of acceleration of the notes, the principal, premium, if any, and interest on the notes will not be payable until the earlier of:

(1)   the day which is five business days after written notice of acceleration is received by the Company and the Credit Agent; or

(2)   the date of acceleration of the Indebtedness under the Credit Agreement. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary, the principal of, and premium, if any, and any accrued and unpaid interest on all outstanding notes will become due and payable without further action or notice.

Holders of the notes may not enforce the Indenture or the notes except as provided in the Indenture. In the event of a declaration of acceleration of the notes because an Event of Default has occurred and is continuing as a result of the acceleration of any Indebtedness described in clause (5) above, the declaration of acceleration of the notes shall be automatically annulled if the holders of any Indebtedness described in clause (5) have rescinded the declaration of acceleration in respect of such Indebtedness within 30 days from the date of such declaration and if:

(1)   the annulment of the acceleration of the notes would not conflict with any judgment or decree of a competent jurisdiction; and

S-42

---

Table of Contents

(2)   all existing Events of Default, except non-payment of principal or interest on the notes that became due solely because of the acceleration of the notes, have been cured or waived.

In the case of any Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding payment of the Make-Whole Price or premium, as applicable, that the Company would have had to pay if the Company then had elected to redeem the notes pursuant to the optional redemption provisions of the Indenture, the applicable Make-Whole Price, or an equivalent premium, as the case may be, shall become and be immediately due and payable to the extent permitted by law upon the acceleration of the notes.

The Holders of a majority in aggregate principal amount of the notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium or interest) if it determines that withholding notice is in their interest.

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

No personal liability of directors, officers, employees and stockholders

No director, officer, employee, incorporator or stockholder of the Company or any Restricted Subsidiary, as such, shall have any liability for any obligations of the Company or any Restricted Subsidiary under the notes, the subsidiary guarantees or the Indenture 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 and the subsidiary guarantees waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes and the subsidiary guarantees. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

Legal defeasance and covenant defeasance

The Company may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding notes, or Legal Defeasance, except for:

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

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

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

(4)   the Legal Defeasance provisions of the Indenture.

In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants, including the one described above under the caption "Reports," that are described in the Indenture, or Covenant Defeasance, and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership and insolvency events) described under "Events of default and remedies" 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 Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the notes, cash in Dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the outstanding notes on the stated maturity or on the applicable redemption date, as the case may be, of such principal or installment of principal of, premium, if any, or interest on the outstanding notes;

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

(3)   in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax

S-44

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 the deposit described in clause (1) above, 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 shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6)   the Company shall have delivered to the Trustee an opinion of counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally;

(7)   the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(8)   the Company shall have delivered to the Trustee an Officers' Certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Book-entry, delivery and form

The notes will be issued in the form of one or more fully registered global notes in book entry form, which will be deposited with, or on behalf of, DTC and registered in the name of DTC's nominee, Cede & Co. Except as set forth below, the global notes may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor of DTC or a nominee of such successor.

So long as DTC or its nominee is the registered owner of a global note, DTC or its nominee, as the case may be, will be considered the sole holder of the notes represented by such global note for all purposes under the indenture and the beneficial owners of the notes will be entitled only to those rights and benefits afforded to them in accordance with DTC's regular operating procedures. Upon specified written instructions of a participant in DTC, DTC will have its nominee assist participants in the exercise of certain holders' rights, such as demand for acceleration of maturity or an instruction to the trustee. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes registered in their names, will not receive or be entitled to receive physical delivery of notes in certificated form and will not be considered the registered owners or holders thereof under the indenture.

If (1) DTC is at any time unwilling or unable to continue as depository or if at any time DTC ceases to be a clearing agency registered under the Exchange Act and a successor depository is not appointed by us within 90 days, (2) an event of default under the indenture relating to the notes has occurred and is continuing and the beneficial owners representing a majority in principal amount of notes advise DTC to cease acting as depository for the notes or (3) we, in

S-45

Table of Contents

our sole discretion, determine at any time that the notes shall no longer be represented by a global note, we will issue individual notes in certificated form of the same series and like tenor and in the applicable principal amount in exchange for the notes represented by the global note. In any such instance, an owner of a beneficial interest in a global note will be entitled to physical delivery of individual notes in certificated form of the same series and like tenor, equal in principal amount to such beneficial interest and to have the notes in certificated form registered in its name. Notes so issued in certificated form will be issued in denominations of $2,000 or any integral multiple of $1,000 in excess thereof and will be issued in registered form only, without coupons.

The following is based on information furnished by DTC:

DTC will act as securities depository for the notes. The notes will be issued as fully registered notes registered in the name of Cede & Co. (DTC's partnership nominee) or such other name as may be requested by an authorized representative of DTC.

DTC, the world's largest securities depository, is a limited purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for almost 2.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues and money market instruments from over 100 countries that DTC's direct participants deposit with DTC.

DTC also facilitates the post trade settlement among direct participants of sales and other securities transactions in deposited securities, through electronic computerized book entry transfers and pledges between direct participants' accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. Access to the DTC system is also available to others such as both U.S. and non U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. DTC has Standard & Poor's highest rating: AAA. The DTC rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com.

Purchases of the notes under the DTC system must be made by or through direct participants, which will receive a credit for the notes on DTC's records. The beneficial interest of each actual purchaser of each note is in turn to be recorded on the direct and indirect participants' records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of beneficial interests in the notes are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their beneficial interests in notes, except in the event that use of the book entry system for the notes is discontinued. The laws of some states require that

S-46

---

Table of Contents

certain persons take physical delivery in definitive form of securities which they own. Such limits and such laws may impair the ability of such persons to own, transfer or pledge beneficial interests in a global note.

To facilitate subsequent transfers, all notes deposited by direct participants with DTC will be registered in the name of DTC's partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of the notes with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes; DTC's records reflect only the identity of the direct participants to whose accounts the notes will be credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial owners of the notes may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the notes, such as redemption, tenders, defaults, and proposed amendments to the security documents. For example, beneficial owners of the notes may wish to ascertain that the nominee holding the notes for their benefit has agreed to obtain and transmit notices to beneficial owners. In the alternative, beneficial owners may wish to provide their names and addresses to the registrar of the notes and request that copies of the notices be provided to them directly. Any such request may or may not be successful.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the notes unless authorized by a direct participant in accordance with DTC's procedures. Under its usual procedures, DTC mails an Omnibus Proxy to us as soon as possible after the regular record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those direct participants to whose accounts the notes are credited on the record date (identified in a listing attached to the Omnibus Proxy).

We will pay principal of and interest, premium, if any, and Make-Whole Amount, if any, on the notes in same day funds to the trustee and from the trustee to DTC, or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit direct participants' accounts on the applicable payment date in accordance with their respective holdings shown on DTC's records upon DTC's receipt of funds and corresponding detail information. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of these participants and not of us, the trustee, DTC, or any other party, subject to any statutory or regulatory requirements that may be in effect from time to time. Payment of principal, interest, premium, if any, and Make-Whole Amount, if any, to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is the responsibility of us or the trustee, disbursement of such payments to direct participants is the responsibility of DTC, and disbursement of such payments to the beneficial owners is the responsibility of the direct or indirect participants.

S-47

Table of Contents

We will send any redemption notices to DTC. If less than all of the notes are being redeemed, DTC's practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

DTC may discontinue providing its services as securities depository for the notes at any time by giving us reasonable notice. Under such circumstances, if a successor securities depository is not obtained, we will print and deliver certificated notes. We may decide to discontinue use of the system of book entry transfers through DTC (or a successor securities depository). In that event, we will print and deliver certificated notes.

We, the underwriters and the trustee will have no responsibility or liability for any aspect of the records relating to or payments made on account of the beneficial interests in a global note, or for maintaining, supervising or reviewing any records relating to such beneficial interests.

The information in this section concerning DTC and DTC's system has been obtained from sources that we believe to be reliable, but we take no responsibility for its accuracy.

Same-day settlement and payment

The underwriters will make settlement for the notes in immediately available funds. We will make all payments of principal and interest in respect of the notes in immediately available funds.

The notes will trade in DTC's Same-Day Funds Settlement System until maturity or until the notes are issued in certificated form, and secondary market trading activity in the notes will therefore be required by DTC to settle in immediately available funds. We expect that secondary trading in the certificated securities, if any, will also be settled in immediately available funds. No assurance can be given as to the effect, if any, of settlement in immediately available funds on trading activity in the notes.

Amendment, supplement and waiver

Except as provided in the next two succeeding paragraphs, the Indenture or the notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for notes), and any existing default or compliance with any provision of the Indenture or the notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding notes (including consents obtained in connection with a tender offer or exchange offer for notes).

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

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

(2)   reduce the principal of or change the fixed maturity of any note or alter the provisions with respect to the redemption of the notes in a manner adverse to the Holders of the notes;

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

S-48

Table of Contents

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

(5)   make any note payable in money other than that stated in the notes;

(6)   make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders of notes to receive payments of principal of or premium, if any, or interest on the notes;

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

(8)   except pursuant to the Indenture, release any Restricted Subsidiary from its obligations under its subsidiary guarantee, or change any subsidiary guarantee in any manner that would materially adversely affect the Holders; or

(9)   make any change in the foregoing amendment and waiver provisions.

Notwithstanding the foregoing, without the consent of any Holder of notes, the Company and the Trustee may amend or supplement the Indenture or the notes to cure any ambiguity, defect or inconsistency, to provide for uncertificated notes in addition to or in place of certificated notes, to provide for the assumption of the Company's obligations to Holders of the notes in the case of a merger, consolidation or amalgamation, to make any change that would provide any additional rights or benefits to the Holders of the notes or that does not adversely affect the legal rights under the Indenture of any such Holder, or to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.

Concerning the trustee

The Indenture contains certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payment of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions. However, if it acquires any conflicting interest it must eliminate such conflict within 90 days, resign or apply to the SEC for permission to continue.

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

Material federal income tax considerations

General

The following summary of federal income tax considerations is based upon the Internal Revenue Code of 1986, as amended, Treasury regulations, and rulings and decisions now in effect, all of which are subject to change, possibly with retroactive effect, or possible differing interpretations. We have not sought a ruling from the Internal Revenue Service, or the IRS, with respect to any matter described in this summary, and we cannot provide any assurance that the IRS or a court will agree with the statements made in this summary. The summary applies to you only if you hold our notes as a capital asset, which generally is an asset held for investment rather than as inventory or as property used in a trade or business. The summary does not discuss all of the particular tax consequences that might be relevant to you if you are subject to special rules under the federal income tax law, for example, if you are:

•

a bank, life insurance company, regulated investment company or other financial institution,

•

a broker, dealer or trader in securities or foreign currency,

•

a person that has a functional currency other than the U.S. dollar,

•

a person who acquires our notes in connection with employment or other performance of services,

•

a person subject to alternative minimum tax,

•

a person who owns our notes as part of a straddle, hedging transaction, conversion transaction or constructive sale transaction,

•

a tax-exempt entity, or

•

an expatriate.

In addition, the following summary does not address all possible tax considerations relating to the acquisition, ownership and disposition of our notes, and in particular does not discuss any estate, gift, generation-skipping transfer, state, local or foreign tax considerations. For all these reasons, we encourage you to consult with your tax advisor about the federal income tax and other tax consequences of your acquisition, ownership and disposition of our notes.

For purposes of this summary, you are a "U.S. holder" if you are a beneficial owner of our notes and for federal income tax purposes are:

•

a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or meets the substantial presence residency test under the federal income tax laws,

•

a corporation or other entity treated as a corporation for federal income tax purposes, that is created or organized in or under the laws of the United States, any state thereof or the District of Columbia,

•

an estate the income of which is subject to federal income taxation regardless of its source, or

S-65

Table of Contents

•

a trust if 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 an electing trust in existence on August 20, 1996 to the extent provided in Treasury regulations,

and if your status as a U.S. holder is not overridden pursuant to the provisions of an applicable tax treaty. Conversely, you are a "non-U.S. holder" if you are a beneficial owner of our notes and are not a U.S. holder. If an entity treated as a partnership for U.S. federal income tax purposes holds notes, the tax treatment of each partner will depend on the status of the partner and the activities and status of the partnership. We encourage you to consult your tax advisor if you are a partner in a partnership that holds notes.

We would be required to pay you a premium if you require us to repurchase your notes on a Change of Control. Because we believe the likelihood that we will be obligated to make any such additional payment on the notes is remote, we intend to take the position (and this discussion assumes) that the notes will not be treated as contingent payment debt instruments under the applicable Treasury regulations. Our determination that the notes are not contingent payment debt instruments is not binding on the IRS. Our determination that the notes are not contingent payment debt instruments is binding on you unless you disclose your contrary position to the IRS in the manner prescribed by applicable Treasury regulations.

Tax consequences for U.S. holders

If you are a U.S. holder:

Payments of interest.    You must generally include interest on a note in your gross income as ordinary interest income:

•

when you receive it, if you use the cash method of accounting for federal income tax purposes, or

•

when it accrues, if you use the accrual method of accounting for federal income tax purposes.

Purchase price for a note that is allocable to prior accrued interest may be treated as offsetting a portion of the interest income from the next scheduled interest payment on the note. Any interest income so offset is not taxable.

Assuming our position that the notes are not contingent payment debt instruments is respected, you would be required to treat any payments of premium as amounts realized upon the repurchase of the notes. If the IRS were to challenge successfully our determination and the notes were treated as contingent payment debt instruments, you might be required, among other things, to accrue interest income (regardless of your method of accounting for federal income tax purposes) at a rate higher than the stated interest rate on the notes, and treat as ordinary income, rather than capital gain, any gain recognized on a sale, exchange or redemption of a note.

Market discount.    If you acquire a note and your adjusted tax basis in it upon acquisition is less than its principal amount, you will be treated as having acquired the note at a "market discount" unless the amount of this market discount is less than the de minimis amount (generally 0.25% of the principal amount of the note multiplied by the number of remaining

S-66

---

Table of Contents

whole years to maturity of the note). Under the market discount rules, you will be required to treat any gain on the sale, exchange, redemption, retirement, or other taxable disposition of a note, or any appreciation in a note in the case of certain nontaxable dispositions such as a gift, as ordinary income to the extent of the market discount which has not previously been included in your income and which is treated as having accrued on the note at the time of the disposition. In addition, you may be required to defer, until the maturity of the note or earlier taxable disposition, the deduction of all or a portion of the interest expense on any indebtedness incurred or continued to purchase or carry the note. Any market discount will be considered to accrue ratably during the period from the date of your acquisition to the maturity date of the note, unless you elect to accrue the market discount on a constant yield method. In addition, you may elect to include market discount in income currently as it accrues, on either a ratable or constant yield method, in which case the rule described above regarding deferral of interest deductions will not apply. This election to include market discount in income currently, once made, applies to all market discount obligations acquired by you during or after the first taxable year to which the election applies and may not be revoked without the consent of the IRS. We encourage you to consult with your tax advisor regarding these elections.

Amortizable bond premium.    If you acquire a note and your adjusted tax basis in it upon acquisition is greater than its principal amount, you will be treated as having acquired the note with "bond premium." You generally may elect to amortize this bond premium over the remaining term of the note on a constant yield method, and the amount amortized in any year will be treated as a reduction of your interest income from the note for that year. If the amount of your bond premium amortization would be lower if calculated based on an earlier optional redemption date and the redemption price on that date than the amount of amortization calculated through that date based on the note's maturity date and its stated principal amount, then you must calculate the amount and timing of your bond premium amortization deductions assuming that the note will be redeemed on the optional redemption date at the optional redemption price. You may generally recalculate your bond premium amortization amount and schedule of deductions to the extent your note is not actually redeemed at that earlier optional redemption date. If you do not make an election to amortize bond premium, your bond premium on a note will decrease the gain or increase the loss that you otherwise recognize on a disposition of that note. Any election to amortize bond premium applies to all taxable debt obligations that you hold at the beginning of the first taxable year to which the election applies and that you thereafter acquire. You may not revoke an election to amortize bond premium without the consent of the IRS. We encourage you to consult with your tax advisor regarding this election.

Disposition of a note.    Upon the sale, exchange, redemption, retirement or other disposition of a note, you generally will recognize taxable gain or loss in an amount equal to the difference, if any, between (1) the amount you receive in cash or in property, valued at its fair market value, upon this sale, exchange, redemption, retirement or other disposition, other than amounts representing accrued and unpaid interest which will be taxable as interest income, and (2) your adjusted tax basis in the note. Your adjusted tax basis in the note will, in general, equal your acquisition cost for the note, exclusive of any amount paid allocable to prior accrued interest, as increased by any market discount you have included in income in respect of the note, and as decreased by any amortized bond premium on the note. Except to the extent of any accrued market discount not previously included in income, as discussed above, your

S-67

Table of Contents

gain or loss will be capital gain or loss, and will be long-term capital gain or loss if you have held the note for more than one year at the time of disposition. For noncorporate U.S. holders, preferential rates of tax may apply to long-term capital gains. The deductibility of capital losses is subject to limitation.

Medicare contribution tax.    For taxable years beginning after December 31, 2012, U.S. holders who are individuals, estates or certain trusts will generally be required to pay a new 3.8% Medicare tax on their net investment income (including interest on our notes and gains from the disposition of our notes), or in the case of estates and trusts on their net investment income that is not distributed, in each case to the extent that their total adjusted income exceeds applicable thresholds.

Tax consequences for non-U.S. holders

If you are a non-U.S. holder:

Generally.    You will not be subject to federal income taxes on payments of principal, premium, if any, or interest on a note, or upon the sale, exchange, redemption, retirement or other disposition of a note, if:

•

you do not own directly or indirectly 10% or more of the total voting power of all classes of our voting stock,

•

your income and gain in respect of the note is not effectively connected with the conduct of a United States trade or business,

•

you are not a controlled foreign corporation that is related to or under common control with us,

•

we or the applicable paying agent, or the Withholding Agent, have timely received from you a properly executed, applicable IRS Form W-8 or substantially similar form in the year in which a payment of interest, principal or premium occurs, or in a previous calendar year to the extent provided for in the instructions to the applicable IRS Form W-8, and

•

in the case of gain upon the sale, exchange, redemption, retirement or other disposition of a note recognized by an individual non-U.S. holder, you were present in the United States for less than 183 days during the taxable year in which the gain was recognized.

The IRS Form W-8 or a substantially similar form must be signed by you under penalties of perjury certifying that you are a non-U.S. holder and providing your name and address, and you must inform the Withholding Agent of any change in the information on the statement within 30 days of the change. If you hold a note through a securities clearing organization or other qualified financial institution, the organization or institution may provide a signed statement to the Withholding Agent. However, in that case, the signed statement must generally be accompanied by a statement containing the relevant information from the executed IRS Form W-8 or substantially similar form that you provided to the organization or institution. If you are a partner in a partnership holding our notes, both you and the partnership must comply with applicable certification requirements.

Except in the case of income or gain in respect of a note that is effectively connected with the conduct of a United States trade or business, discussed below, interest received or gain

S-68

Table of Contents

recognized by you which does not qualify for the above or other exemptions from taxation will be subject to federal income tax at a rate of 30%, which will be withheld in the case of interest, unless reduced or eliminated by an applicable tax treaty. You must generally use an applicable IRS Form W-8, or a substantially similar form, to claim tax treaty benefits. If you are a non-U.S. holder claiming benefits under an income tax treaty, you should be aware that you may be required to obtain a taxpayer identification number and to certify your eligibility under the applicable treaty's limitations on benefits article in order to comply with the applicable certification requirements of the Treasury regulations.

Effectively connected income and gain.    If you are a non-U.S. holder whose income and gain in respect of a note are effectively connected with the conduct of a United States trade or business (and, if provided by an applicable income tax treaty, are attributable to a permanent establishment or fixed base you maintain in the United States), you will be subject to regular federal income tax on this income and gain in generally the same manner as U.S. holders, and general federal income tax return filing requirements will apply. In addition, if you are a corporation, you may be subject to a branch profits tax equal to 30% of your effectively connected adjusted earnings and profits for the taxable year, unless you qualify for a lower rate under an applicable tax treaty. To obtain an exemption from withholding on interest on the notes, you must generally supply to the Withholding Agent an applicable IRS Form W-8, or a substantially similar form.

Information reporting and backup withholding

Information reporting and backup withholding may apply to interest and other payments to you under the circumstances discussed below. Amounts withheld under backup withholding are generally not an additional tax and may be refunded or credited against your federal income tax liability, provided that you furnish the required information to the IRS. The backup withholding rate is currently 28% and is scheduled to increase to 31% after 2012.

After December 31, 2012, the reporting obligations of non-U.S. financial institutions and other non-U.S. entities for purposes of identifying accounts and investments held directly or indirectly by U.S. persons are increased. Failure to comply with the additional reporting obligations after that date may result in a 30% withholding tax on applicable payments to non-U.S. persons. IRS guidance issued in July 2011 indicates that regulations will be issued that will provide that such withholding will only apply to payments of interest made on or after January 1, 2014, and to other "withholdable payments" (including payments of gross proceeds from a sale or other disposition of certain debt instruments) made on or after January 1, 2015. Moreover, this withholding tax will not be imposed on payments pursuant to a debt obligation outstanding as of March 18, 2012. Accordingly, we do not anticipate that these withholding rules will apply to the notes.

If you are a U.S. holder.    You may be subject to backup withholding when you receive interest payments on a note or proceeds upon the sale, exchange, redemption, retirement or other disposition of a note. In general, you can avoid this backup withholding if you properly execute under penalties of perjury an IRS Form W-9 or a substantially similar form on which you:

•

provide your correct taxpayer identification number;

S-69

---

Table of Contents

•

certify that you are exempt from backup withholding because (a) you are a corporation or come within another enumerated exempt category, (b) you have not been notified by the IRS that you are subject to backup withholding, or (c) you have been notified by the IRS that you are no longer subject to backup withholding; and

•

certify that you are a U.S. citizen or other U.S. person.

If you do not provide your correct taxpayer identification number on the IRS Form W-9 or a substantially similar form, you may be subject to penalties imposed by the IRS.

Unless you have established on a properly executed IRS Form W-9 or a substantially similar form that you come within an enumerated exempt category, interest and other payments on the notes paid to you during the calendar year, and the amount of tax withheld, if any, will be reported to you and to the IRS.

If you are a non-U.S. holder.    The amount of interest paid to you on a note during each calendar year, and the amount of tax withheld, if any, will generally be reported to you and to the IRS. This information reporting requirement applies regardless of whether you were subject to withholding or whether withholding was reduced or eliminated by an applicable tax treaty. Also, interest paid to you on a note may be subject to backup withholding unless you properly certify your non-U.S. holder status on an IRS Form W-8 or a substantially similar form in the manner described above, under "Tax Consequences for non-U.S. holders." Similarly, information reporting and backup withholding will not apply to proceeds you receive upon the sale, exchange, redemption, retirement or other disposition of a note, if you properly certify that you are a non-U.S. holder on an IRS Form W-8 or a substantially similar form. Even without having executed an IRS Form W-8 or a substantially similar form, however, in some cases information reporting and backup withholding may not apply to proceeds you receive upon the sale, exchange, redemption, retirement or other disposition of a note, if you receive those proceeds through a broker's foreign office.

Underwriting

Subject to the terms and conditions set forth in an underwriting agreement among us, the guarantors and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed to purchase from us, the principal amount of notes set forth opposite its name below.

The obligations of the underwriters under the underwriting agreement, including their agreement to purchase notes from us, are several and not joint. The underwriting agreement provides that the underwriters will purchase all the notes if any of them are purchased.

In the underwriting agreement, we and the guarantors have agreed to indemnify each underwriter against certain liabilities in connection with this offering, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make in respect thereof.

Discounts

The underwriters propose initially to offer the notes to the public at the public offering price listed on the cover page of this prospectus supplement and may offer notes to selected dealers at that price less a concession not in excess of             % of the principal amount of the notes. In addition, the underwriters may allow, and those selected dealers may reallow, a concession not in excess of             % of the principal amount of the notes to certain other dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates.

S-71

---

Table of Contents

The following table shows the underwriting discounts and commissions to be paid to the underwriters by us.

New issue of notes

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure you that a liquid trading market for the notes will develop, that you will be able to sell your notes at a particular time or that prices you receive when you sell will be favorable.

Price stabilization and short positions

In connection with the offering of the notes, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

Other relationships

Some or all of the underwriters and/or their affiliates have engaged in, and/or may in the future engage in, investment banking, commercial banking, financial advisory and other commercial dealings in the ordinary course of business with us. They have received customary fees and commissions for these transactions.

If any of the underwriters or their respective affiliates have a lending relationship with us, certain of those underwriters or their respective affiliates routinely hedge, and certain other of those underwriters or their respective affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

RISK FACTORS

        Investment in any securities offered pursuant to this prospectus involves risk. You should carefully consider the risk factors incorporated by reference from our most recent Annual Report on Form 10-K and the other information contained in this prospectus, as updated by our subsequent filings under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement before acquiring any of such securities.

RATIO OF EARNINGS TO FIXED CHARGES

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

        The ratios of earnings to fixed charges presented above were computed by dividing our earnings by fixed charges. For this purpose, earnings have been calculated by adding fixed charges to income (loss) from continuing operations before provision for income taxes. Fixed charges consist of interest costs, the interest component of rental expense and amortization of debt discounts and deferred financing costs, but do not include interest expense related to uncertain tax positions.

USE OF PROCEEDS

        Unless otherwise described in a prospectus supplement, we intend to use the net proceeds from the sale of the offered securities for general corporate purposes, which may include acquisitions, investments and the repayment of indebtedness outstanding at a particular time. Pending this utilization, the proceeds from the sale of the offered securities will be invested in short-term, dividend-paying or interest-bearing investment grade securities.

DESCRIPTION OF OUR DEBT SECURITIES

        The following is a summary of the material terms of our debt securities. Because it is a summary, it does not contain all of the information that may be important to you. If you want more information, you should read the forms of indentures which we have filed as exhibits to the registration statement of which this prospectus is a part. We will file any final indentures and/or supplemental indentures if we issue debt securities. See "Where You Can Find More Information." This summary is also subject to and qualified by reference to the descriptions of the particular terms of your securities described in the applicable prospectus supplement.

        The debt securities will be direct obligations of ours, which may be secured or unsecured, and which may be senior or subordinated indebtedness. The debt securities may be fully and unconditionally guaranteed on a secured or unsecured, senior or subordinated basis, jointly and severally by substantially all of our direct and indirect wholly owned domestic subsidiaries. Our debt securities will be issued under one or more indentures between us and a trustee. Any indenture will be subject to, and governed by, the Trust Indenture Act of 1939. The statements made in this prospectus relating to any indentures and the debt securities to be issued under the indentures are summaries of certain anticipated provisions of the indentures and are not complete.

General

        We may issue debt securities that rank "senior," "senior subordinated" or "subordinated." The debt securities that we refer to as "senior securities" will be direct obligations of ours and will rank equally and ratably in right of payment with other indebtedness of ours that is not subordinated. We may issue debt securities that will be subordinated in right of payment to the prior payment in full of senior indebtedness, as defined in the applicable prospectus supplement, and may rank equally and ratably with our outstanding senior subordinated indebtedness and any other senior subordinated indebtedness. We refer to these as "senior subordinated securities." We may also issue debt securities that may be subordinated in right of payment to the senior subordinated securities. These would be "subordinated securities." We have filed with the registration statement of which this prospectus is part four separate forms of indenture, one each for the senior securities and the subordinated securities and two for the senior subordinated securities.

        We may issue the debt securities without limit as to aggregate principal amount, in one or more series, in each case as we establish in one or more supplemental indentures. We need not issue all debt securities of one series at the same time. Unless we otherwise provide, we may reopen a series, without the consent of the holders of such series, for issuances of additional securities of that series.

        We anticipate that any indenture will provide that we may, but need not, designate more than one trustee under an indenture, each with respect to one or more series of debt securities. Any trustee under any indenture may resign or be removed with respect to one or more series of debt securities, and we may appoint a successor trustee to act with respect to that series.

        The applicable prospectus supplement will describe the specific terms relating to the series of debt securities we will offer, including, where applicable, the following:

•

the title and series designation and whether they are senior securities, senior subordinated securities or subordinated securities;



•

the aggregate principal amount of the securities;



•

the percentage of the principal amount at which we will issue the debt securities and, if other than the principal amount of the debt securities, the portion of the principal amount of the debt securities payable upon maturity of the debt securities;

2

---

•

if convertible, the initial conversion price, the conversion period and any other terms governing such conversion;



•

the stated maturity date;



•

any fixed or variable interest rate or rates per annum;



•

the place where principal, premium, if any, and interest will be payable and where the debt securities can be surrendered for transfer, exchange or conversion;



•

the date from which interest may accrue and any interest payment dates;



•

any sinking fund requirements;



•

any provisions for redemption, including the redemption price and any remarketing arrangements;



•

whether the securities are denominated or payable in U.S. dollars or a foreign currency or units of two or more foreign currencies;



•

the events of default and covenants of such securities, to the extent different from or in addition to those described in this prospectus;



•

whether we will issue the debt securities in certificated or book-entry form;



•

whether the debt securities will be in registered or bearer form and, if in registered form, the denominations if other than in even multiples of $1,000 and, if in bearer form, the denominations and terms and conditions relating thereto;



•

whether we will issue any of the debt securities in permanent global form and, if so, the terms and conditions, if any, upon which interests in the global security may be exchanged, in whole or in part, for the individual debt securities represented by the global security;



•

the applicability, if any, of the defeasance and covenant defeasance provisions described in this prospectus or any prospectus supplement;



•

whether we will pay additional amounts on the securities in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities instead of making this payment;



•

the subordination provisions, if any, relating to the debt securities;



•

if the debt securities are to be issued upon the exercise of debt warrants, the time, manner and place for them to be authenticated and delivered;



•

whether any of our subsidiaries will be bound by the terms of the indenture, in particular any restrictive covenants;



•

the provisions relating to any security provided for the debt securities; and



•

the provisions relating to any guarantee of the debt securities.

        We may issue debt securities at less than the principal amount payable upon maturity. We refer to these securities as "original issue discount securities." We may also issue debt securities over par from time to time. If material or applicable, we will describe in the applicable prospectus supplement special U.S. federal income tax, accounting and other considerations applicable to original issue discount securities or debt securities issued over par.

        Except as may be set forth in any prospectus supplement, an indenture will not contain any other provisions that would limit our ability to incur indebtedness or that would afford holders of the debt securities protection in the event of a highly leveraged or similar transaction involving us or in the

3

---

event of a change of control. You should review carefully the applicable prospectus supplement for information with respect to events of default and covenants applicable to the securities being offered.

Denominations, Interest, Registration and Transfer

        Unless otherwise described in the applicable prospectus supplement, we will issue the debt securities of any series that are registered securities in denominations that are even multiples of $1,000, other than global securities, which may be of any denomination.

        Unless otherwise specified in the applicable prospectus supplement, we will pay the interest, principal and any premium at the corporate trust office of the trustee. At our option, however, we may make payment of interest by check mailed to the address of the person entitled to the payment as it appears in the applicable register or by wire transfer of funds to that person at an account maintained within the United States.

        If we do not punctually pay or duly provide for interest on any interest payment date, the defaulted interest will be paid either:

•

to the person in whose name the debt security is registered at the close of business on a special record date we will fix; or



•

in any other lawful manner as the applicable indenture describes.

        You may have your debt securities divided into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. We call this an "exchange."

        You may exchange or transfer debt securities at the office of the applicable trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. We may change this appointment to another entity or perform it ourselves. The entity performing the role of maintaining the list of registered holders is called the "registrar." It will also perform transfers.

        You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The registrar will make the transfer or exchange only if it is satisfied with your proof of ownership.

Merger, Consolidation or Sale of Assets

        Under any indenture, we are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company. However, we may not take any of these actions unless all of the following conditions are met:

•

If we merge out of existence or sell our assets, the other company must be a corporation, partnership or other entity organized under the laws of a State or the District of Columbia or under federal law. The other company must agree to be legally responsible for the debt securities.



•

Immediately after the consolidation or merger or sale of assets we are not in default on the debt securities. A default for this purpose would include any event that would be an event of default without regard to notice obligations or the length of time of the default.

Certain Covenants

        Provision of Financial Information.    We will deliver to the trustee a copy of our annual report to stockholders, our reports on Forms 10-K, 10-Q and 8-K and any other reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

4

---

        Additional Covenants.    Any additional or different covenants, or modifications to these covenants, with respect to any series of debt securities will be set forth in the applicable prospectus supplement.

Events of Default and Related Matters

        Events of Default.    The term "event of default" means any of the following:

•

we do not pay the principal or any premium on a debt security on its due date;



•

we do not pay interest on a debt security within 30 days of its due date;



•

we do not deposit any sinking fund payment on its due date;



•

we fail to comply with any "change of control" covenant included in the applicable indenture;



•

we remain in breach of any other term of the applicable indenture for 60 days after we receive a notice of default stating we are in breach. Either the trustee or the holders of 25% in principal amount of debt securities of the affected series may send the notice;



•

we default in the payment of any of our other indebtedness over a specified amount that results in the acceleration of the maturity of the indebtedness or constitutes a default in the payment of the indebtedness at final maturity, but only if the indebtedness is not discharged or the acceleration is not rescinded or annulled;



•

we or one of our "significant subsidiaries" files for bankruptcy or certain other events in bankruptcy, insolvency or reorganization occur;



•

a final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the us or any of our "significant subsidiaries" and such judgments remain unpaid, undischarged or unstayed for a period of 60 days, provided that the aggregate of all such unpaid, undischarged or unstayed judgments exceeds $50.0 million;



•

any guarantee issued by a "significant subsidiary" shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or any "significant subsidiary" or any person acting on behalf of any "significant subsidiary" shall deny or disaffirm in writing its obligations under its guarantee; and



•

any other event of default, or modification of any of the foregoing events of default, described in the applicable prospectus supplement occurs.

The term "significant subsidiary" means each of our significant subsidiaries (as defined in Regulation S-X promulgated under the Securities Act of 1933, as amended, or the Securities Act).

        Remedies If an Event of Default Occurs.    If an event of default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the debt securities of the affected series may declare the entire principal amount of all the debt securities of that series to be due and immediately payable. We call this a "declaration of acceleration of maturity." If an event of default occurs because of certain events in bankruptcy, insolvency or reorganization, the principal amount of all the debt securities of that series will be automatically accelerated, without any action by the trustee or any holder. At any time after the trustee or the holders have accelerated any series of debt securities, the holders of at least a majority in principal amount of the debt securities of the affected series may, under certain circumstances, rescind and annul such acceleration.

        The trustee will be required to give notice to the holders of debt securities within 90 days of a default of which the trustee has knowledge under the applicable indenture unless the default has been cured or waived. The trustee may withhold notice to the holders of any series of debt securities of any default with respect to that series, except a default in the payment of the principal of or interest on any debt security of that series, if specified responsible officers of the trustee in good faith determine that withholding the notice is in the interest of the holders.

5

---

        The trustee is not required to take any action under the applicable indenture at the request of any holders unless the holders offer the trustee protection reasonably satisfactory to it from expenses and liability. We refer to this as an "indemnity." If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture, subject to certain limitations.

        Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

•

you must give the trustee written notice that an event of default has occurred and remains uncured;



•

the holders of at least 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default and must offer indemnity satisfactory to the trustee against the costs, expenses and other liabilities of taking that action;



•

the trustee must have not taken action for 60 days after receipt of the above notice, request and offer of indemnity; and



•

the trustee does not receive direction contrary to the holders' written request, within 60 days following receipt of the holders' written request, from holders of a majority in principal amount of the outstanding securities of that series.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your security after its due date.

        Every year we will furnish to the trustee a written statement by certain of our officers certifying that, to their knowledge, we are in compliance with the applicable indenture and the debt securities, or else specifying any default.

Modification of an Indenture

        There are three types of changes we can make to the indentures and the debt securities:

        Changes Requiring Your Approval.    First, there are changes we cannot make to your debt securities without your specific approval. The following is a list of those types of changes:

•

reduce the principal amount of debt securities whose holders must consent to an amendment, supplement or waiver;



•

reduce the principal of or change the fixed maturity of any security or change any of the redemption provisions in a manner adverse to you;



•

reduce the rate of or change the time for payment of interest on any debt security;



•

waive a default in the payment of principal of or premium, if any, or interest on any debt security (except a rescission of acceleration of such debt securities by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities and a waiver of the payment default that resulted from such acceleration);



•

make any debt security payable in money other than that stated in such debt security;



•

make any change in the provisions of the indenture relating to waivers of past defaults or your right to receive payments of principal of or premium, if any, or interest on the debt securities;

6

---

•

except under certain circumstances described in the applicable prospectus supplement, waive a redemption payment with respect to any debt security;



•

if the debt securities are guaranteed, other than as described in the applicable prospectus supplement, release any guarantor from its obligations under its subsidiary guarantee, or change any subsidiary guarantee in any manner that would materially adversely affect you; or



•

make any change in the foregoing amendment and waiver provisions.

        Changes Requiring a Majority Vote.    The second type of change to an indenture and the debt securities is the kind that requires a vote in favor by holders of a majority of the principal amount of the particular series of debt securities affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not materially adversely affect holders of the debt securities. We require the same vote to obtain a waiver of a past default. However, we cannot obtain a waiver of a payment default or any other aspect of an indenture or the debt securities listed under "—Changes Requiring Your Approval" unless we obtain your individual consent to the waiver.

        Changes Not Requiring Approval.    The third type of change does not require any vote by holders of debt securities. This type is limited to clarifications and certain other changes that would not materially adversely affect holders of the debt securities.

        Further Details Concerning Voting.    Debt securities are not considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption or if we or one of our affiliates own them. Debt securities are also not eligible to vote if they have been fully defeased as described immediately below under "—Defeasance and Covenant Defeasance—Full Defeasance." For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the debt securities were accelerated to that date because of a default.

Defeasance and Covenant Defeasance

        Full Defeasance.    We can, under particular circumstances, effect a full defeasance of your series of debt securities. By this we mean we can legally release ourselves from any payment or other obligations on the debt securities if we deliver certain certificates and opinions to the trustee and put in place the following arrangements to repay you:

•

We must deposit in trust for your benefit and the benefit of all other direct holders of the debt securities a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates. If the debt securities are denominated in a foreign currency, then we may deposit foreign government notes or bonds.



•

The current federal tax law must be changed or an Internal Revenue Service ruling must be issued permitting the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves. Under current federal tax law, the deposit and our legal release from the debt securities would be treated as though we took back your debt securities and gave you your share of the cash and notes or bonds deposited in trust. In that event, you could recognize gain or loss on the debt securities you would be deemed to have given back to us.



•

We must deliver to the trustee a legal opinion confirming the tax law change described above.



•

No default shall be in effect on the date of deposit or, insofar as bankruptcy and insolvency defaults are concerned, at any time in the period ending on the 91st day after the date of

7

---

deposit (or greater period of time in which any such deposit of trust funds may remain subject to bankruptcy law insofar as those apply to the deposit by us).

•

The full defeasance must not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the applicable indenture) to which we are a party or by which we are bound.



•

We must deliver to the trustee an opinion of counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally and various other opinions of counsel and officers' certificates.

        If we did accomplish a full defeasance, you would have to rely solely on the trust deposit for repayment on the debt securities. You could not look to us for repayment in the unlikely event of any shortfall. The trust deposit would, however, most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent. You would also be released from any subordination provisions.

        Notwithstanding the foregoing, the following rights and obligations shall survive full defeasance:

•

your rights to receive payments from the trust when payments are due;



•

our obligations relating to registration and transfer of securities and lost or mutilated certificates;



•

our obligations to maintain a payment office and to hold moneys for payment in trust;



•

the rights, powers, trusts, duties and immunities of the trustee, and our obligations in connection therewith; and



•

the provisions of the indenture relating to defeasance.

        Covenant Defeasance.    Under current federal tax law, we can make the same type of deposit described above and be released from some of the restrictive covenants in the debt securities. This is called "covenant defeasance." In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and securities set aside in trust to repay the debt securities and you would be released from any subordination provisions. In order to achieve covenant defeasance, we must do certain things, including the following:

•

we must deposit in trust for your benefit and the benefit of all other direct holders of the debt securities a combination of money and U.S. government or U.S. government agency notes or bonds (or, in the case of debt securities denominated in a foreign currency, foreign government notes or bonds) that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates;



•

we must deliver to the trustee a legal opinion confirming that under current federal tax law we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves;



•

no default shall be in effect on the date of deposit or, insofar as bankruptcy and insolvency defaults are concerned, at any time in the period ending on the 91st day after the date of deposit (or greater period of time in which any such deposit of trust funds may remain subject to bankruptcy law insofar as those apply to the deposit by us);



•

the covenant defeasance must not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the applicable indenture) to which we are a party or by which we are bound; and

8

---

•

we must deliver to the trustee an opinion of counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally and various other opinions of counsel and officers' certificates.

        If we accomplish covenant defeasance, we will be released from certain covenants that we will describe in the applicable prospectus supplement. If we accomplish covenant defeasance, you can still look to us for repayment of the debt securities if a shortfall in the trust deposit occurred. If one of the remaining events of default occurs, for example, our bankruptcy, and the debt securities become immediately due and payable, there may be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Subordination

        We will set forth in the applicable prospectus supplement the terms and conditions, if any, upon which any series of senior subordinated securities or subordinated securities is subordinated to debt securities of another series or to other indebtedness of ours. The terms will include a description of:

•

the indebtedness ranking senior to the debt securities being offered;



•

the restrictions, if any, on payments to the holders of the debt securities being offered while a default with respect to the senior indebtedness is continuing;



•

the restrictions, if any, on payments to the holders of the debt securities being offered following an event of default; and



•

provisions requiring holders of the debt securities being offered to remit some payments to holders of senior indebtedness.

Conversion Rights

        The terms and conditions, if any, upon which the debt securities are convertible into shares of our common or preferred stock will be set forth in the prospectus supplement relating thereto. Such terms will include whether the debt securities are convertible into shares of our common or preferred stock, the conversion price (or manner of calculation thereof), the conversion period, provisions as to whether conversion will be at the option of the holders, the events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption of such debt securities and any restrictions on conversion.

Global Securities

        We may issue the debt securities of a series, in whole or in part, in the form of one or more global securities that will be deposited with a depositary identified in the applicable prospectus supplement.

        We anticipate that any global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, or DTC, and will be registered in the name of DTC's nominee, and that the following provisions will apply to the depository arrangements with respect to any global securities. We will describe additional or differing terms of the depository arrangements in the applicable prospectus supplement relating to a particular series of debt securities issued in the form of global securities.

9

---

        DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its direct participants deposit with DTC. DTC also facilitates the clearance and settlement among direct participants of securities transactions through electronic computerized book-entry changes in direct participants' accounts. This eliminates the need for physical movement of securities certificates. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom own DTC. Access to DTC's book-entry system is also available to indirect participants, such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant. The rules applicable to DTC and its participants are on file with the SEC.

        Upon the issuance of a registered global security, DTC will credit, on its book-entry registration and transfer system, the direct participants' accounts with the respective principal or face amounts of the debt securities beneficially owned by the direct participants. Any dealers, underwriters or agents participating in the distribution of the debt securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by DTC, with respect to interests of direct participants, and on the records of direct participants, with respect to interests of persons holding through direct participants.

        So long as DTC or its nominee is the registered owner of a global note, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities evidenced by a global note for all purposes under the indentures. Except as described below, an owner of a beneficial interest in debt securities evidenced by a global note will not be entitled to have any of the debt securities evidenced by such global note registered in its name, will not receive or be entitled to receive physical delivery of any such debt securities in definitive form and will not be considered the owner or holder thereof under the indentures for any purpose, including with respect to the giving of any direction, instructions or approvals to the trustee thereunder. Accordingly, an owner must rely on the procedures of DTC and, if an owner is not a direct participant, on the procedures of the direct participant through which such owner owns its interest to exercise any rights of a "holder" under the indentures. The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to own, pledge or transfer beneficial interests in any global note.

        To facilitate subsequent transfers, all debt securities deposited by direct participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of debt securities with DTC and their registration in the name of Cede & Co. do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities; DTC's records reflect only the identity of the direct participants to whose accounts such debt securities are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

        Payments of principal and interest or additional amounts, if any, will be made by us to Cede & Co., as nominee of DTC, in immediately available funds. DTC's practice is to credit the accounts of direct participants on the applicable payment date in accordance with their respective beneficial interests in the relevant security as shown on the records of DTC. Payments by direct participants to the beneficial owners of debt securities will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of DTC's direct participants. Payment to Cede & Co. is our responsibility. Disbursement of such payments to direct participants is the

10

---

responsibility of DTC. Disbursement of such payments to the beneficial owners is the responsibility of direct and indirect participants. Redemption notices with respect to any debt securities will be sent to DTC. If less than all of the debt securities are to be redeemed, DTC's practice is to determine by lot the amount of interest of each direct participant in such issue to be redeemed.

        Neither we nor the trustee nor any other agent of ours or any agent of the trustee will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

        Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent to vote with respect to the debt securities unless authorized by a direct participant in accordance with DTC's procedures. Under its usual procedures, DTC would mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants to whose accounts debt securities are credited on the record date (identified in a listing attached to the omnibus proxy). We understand that, under existing industry practice, if we request any action of holders or if an owner of a beneficial interest in a global note desires to give or take any action which a holder is entitled to give or take under the indentures, DTC would authorize the direct participants holding the relevant beneficial interest to give or take such action, and such direct participants would authorize beneficial owners through such direct participants to give or take such actions or would otherwise act upon the instructions of beneficial owners holding through them.

        Debt securities which are evidenced by a global note will be exchangeable for certified debt securities with the same terms in authorized denominations only if:

•

DTC notifies us that it is unwilling or unable to continue as depositary or if DTC ceases to be a clearing agency registered under applicable law and a successor depositary is not appointed within 90 days;



•

there shall have occurred and be continuing an event of default; or



•

we determine not to require all of the debt securities to be evidenced by a global note and notify the trustee of our decision, in which case we will issue individual debt securities in denominations of $1,000 and integral multiples thereof.

        The information in this prospectus concerning DTC and DTC's book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for its accuracy or completeness. We assume no responsibility for the performance by DTC or its participants of their respective obligations, including obligations that they have under the rules and procedures that govern their operations.

DESCRIPTION OF OUR CAPITAL STOCK

        The description below summarizes the more important terms of our capital stock. We have previously filed with the SEC copies of our certificate of incorporation and bylaws, as amended. See "Where You Can Find More Information." You should refer to those documents for the complete terms of our capital stock. This summary is subject to and qualified by reference to the description of the particular terms of your securities described in the applicable prospectus supplement.

General

        Our authorized capital stock consists of 400,000,000 shares of common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01 per share.

11

Preferred Stock

        We are authorized to issue up to 10,000,000 shares of preferred stock, $0.01 par value per share.

        This section describes the general terms and provisions of our currently authorized but unissued preferred stock that we may offer from time to time. The applicable prospectus supplement will describe the specific terms of the shares of preferred stock offered through that prospectus supplement. We will file a copy of the certificate of designations that contains the terms of each new series of preferred stock with the SEC each time we issue a new series of preferred stock, and these certificates of designations will be incorporated by reference into the registration statement of which this prospectus is a part. Each certificate of designations will establish the number of shares included in a designated series and fix the designation, powers, privileges, preferences and rights of the shares of each series as well as any applicable qualifications, limitations or restrictions. A holder of our preferred stock should refer to the applicable certificate of designations, our certificate of incorporation and the applicable prospectus supplement for more specific information.

        Our board of directors has been authorized, subject to limitations provided in our certificate of incorporation, to provide for the issuance of shares of our preferred stock in multiple series. No shares of our preferred stock are currently outstanding.

        With respect to each series of our preferred stock, our board of directors has the authority to fix the following terms:

•

the designation of the series;



•

the number of shares within the series;



•

whether the shares are entitled to receive dividends and whether dividends are cumulative;



•

the rate of any dividends, any conditions upon which dividends are payable, and the dates of payment of dividends;



•

whether the shares are redeemable, the redemption price and the terms of redemption;



•

whether the shares are entitled to any rights if we are dissolved or our assets are distributed;



•

whether the shares are convertible or exchangeable, the price or rate of exchange, and the applicable terms and conditions;



•

any restrictions on issuance of shares in the same series or any other series; and



•

your voting rights for the shares you own.

        Holders of our preferred stock will not have preemptive rights with respect to shares of our preferred stock. In addition, rights with respect to shares of our preferred stock will be subordinate to the rights of our general creditors. If we receive the appropriate payment, shares of our preferred stock that we issue will be fully paid and nonassessable.

        As described under "Description of Our Depositary Shares," we may, at our option, elect to offer depositary shares evidenced by depositary receipts. If we elect to do this, each depositary receipt will represent a fractional interest in a share of the particular series of the preferred stock issued and deposited with a depositary. The applicable prospectus supplement will specify that fractional interest.

        We currently plan to use The Bank of New York Mellon Corporation as the registrar and transfer agent of any series of our preferred stock.

12

Common Stock

        Voting Rights.    Holders of common stock are entitled to one vote per share on each matter to be decided by our stockholders, subject to the rights of holders of any series of preferred stock that may be outstanding from time to time. Pursuant to our certificate of incorporation, there are no cumulative voting rights in the election of directors. In an uncontested election of directors, each director shall be elected by the affirmative vote of holders of a majority of the votes properly cast. In a contested election, the directors shall be elected by a plurality of the votes of shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors.

        Dividend Rights and Limitations.    Holders of common stock will be entitled to receive ratably any dividends or distributions that our board of directors may declare from time to time out of funds legally available for this purpose.

        Dividends and other distributions on common stock are also subject to the rights of holders of any series of preferred stock that may be outstanding from time to time and to the restrictions in our credit agreement and indentures. See "—Preferred Stock."

        Liquidation Rights.    In the event of liquidation, dissolution or winding up of our affairs, after payment or provision for payment of all of our debts and obligations and any preferential distributions to holders of shares of preferred stock, if any, the holders of the common stock will be entitled to share ratably in our remaining assets available for distribution.

        Miscellaneous.    All outstanding shares of common stock are validly issued, fully paid and nonassessable. Our board of directors has the power to issue shares of authorized but unissued common stock without further stockholder action. The issuance of these unissued shares could have the effect of diluting the earnings per share and book value per share of currently outstanding shares of common stock. The holders of common stock have no preemptive, subscription, redemption or conversion rights.

        Reference is made to the applicable prospectus supplement relating to the common stock offered by that prospectus supplement for specific terms, including:

•

amount and number of shares offered;



•

the initial offering price, if any, and market price; and



•

information with respect to dividends.

        Transfer Agent and Registrar.    The transfer agent and registrar for our common stock is The Bank of New York Mellon, Shareholder Services, 500 Ross Street, 6th Floor, Pittsburgh, Pennsylvania, 15219. Its telephone number is (800) 524-4458.

DESCRIPTION OF OUR DEPOSITARY SHARES

General

        The description shown below, and in any applicable prospectus supplement, of certain provisions of any deposit agreement and of the depositary shares and depositary receipts representing depositary shares does not purport to be complete and is subject to and qualified in its entirety by reference to the forms of deposit agreement and depositary receipts relating to each applicable series of preferred stock. The deposit agreement and the depositary receipts contain the full legal text of the matters described in this section. We will file a copy of those documents with the SEC at or before the time of the offering of the applicable series of preferred stock. This summary also is subject to and qualified by reference to the description of the particular terms of your series of depositary shares described in the applicable prospectus supplement.

13

---

        We may, at our option, elect to offer depositary shares representing fractional interests in shares of preferred stock, rather than shares of preferred stock. If we exercise this option, we will appoint a depositary to issue depositary receipts representing those fractional interests. Preferred stock of each series represented by depositary shares will be deposited under a separate deposit agreement between us and the depositary. The prospectus supplement relating to a series of depositary shares will disclose the name and address of the depositary. Subject to the terms of the applicable deposit agreement, each holder of depositary shares will be entitled to all of the distribution, voting, conversion, redemption, liquidation and other rights and preferences of the preferred stock represented by those depositary shares.

        Depositary receipts issued pursuant to the applicable deposit agreement will evidence ownership of depositary shares. Upon surrender of depositary receipts at the office of the depositary, and upon payment of the charges provided in and subject to the terms of the deposit agreement, a holder of depositary shares will be entitled to receive the shares of preferred stock underlying the surrendered depositary receipts.

Distributions

        A depositary will be required to distribute all cash distributions received in respect of the applicable preferred stock to the record holders of depositary shares in proportion to the number of depositary shares held by the holders on the relevant record date, which will be the same as the record date fixed by us for the applicable series of preferred stock. Fractions will be rounded down to the nearest whole cent.

        If the distribution is other than in cash, a depositary will be required to distribute property received by it to the record holders of depositary shares entitled thereto, in proportion, as nearly as practicable, to the number of depositary shares owned by those holders on the relevant record date, unless the depositary determines that it is not feasible to make the distribution. In that case, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders.

        Depositary shares that represent preferred stock converted or exchanged will not be entitled to distributions. The deposit agreement will also contain provisions relating to the manner in which any subscription or similar rights we offer to holders of the preferred stock will be made available to holders of depositary shares. All distributions will be subject to obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the depositary.

Withdrawal of Preferred Stock

        Holders of depositary shares may receive the number of whole shares of the applicable series of preferred stock and any money or other property represented by those depositary shares after surrendering the depositary receipts at the corporate trust office of the depositary and paying the charges provided in the depositary agreement. Partial shares of preferred stock will not be issued. If the depositary receipts that a holder surrenders evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock the holder wishes to withdraw, then the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Once a holder has withdrawn the holder's preferred stock, the holder will not be entitled to re-deposit those shares of preferred stock under the deposit agreement in order to receive depositary shares. We do not expect that there will be any public trading market for withdrawn shares of preferred stock.

14

---

Redemption of Depositary Shares

        If we redeem a series of the preferred stock underlying the depositary shares, the depositary will redeem those depositary shares representing the preferred stock so redeemed from the proceeds received by it in connection with the redemption. The depositary will mail notice of redemption not less than 30 and not more than 60 days before the date fixed for redemption to the record holders of the depositary shares we are redeeming at their addresses appearing in the depositary's books. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to the series of the preferred stock. The redemption date for depositary shares will be the same as that of the preferred stock. If we are redeeming less than all of the depositary shares, the depositary will select the depositary shares we are redeeming by lot or pro rata as the depositary may determine.

        After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed outstanding. All rights of the holders of the depositary shares and the related depositary receipts will cease at that time, except the right to receive the money or other property to which the holders of depositary shares were entitled upon redemption. Receipt of the money or other property is subject to surrender to the depositary of the depositary receipts evidencing the redeemed depositary shares.

Voting of the Preferred Stock

        Upon receipt of notice of any meeting at which the holders of preferred stock represented by depositary shares are entitled to vote, a depositary will be required to mail the information contained in the notice of meeting to the record holders of the applicable depositary shares. Each record holder of depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock represented by the holder's depositary shares. The depositary will try, as practical, to vote the depositary shares as instructed by the record holder of depositary shares. We will agree to take all reasonable action that the depositary deems necessary in order to enable it to do so. If a record holder of depositary shares does not instruct the depositary how to vote the holder's depositary shares, the depositary will abstain from voting those shares.

Liquidation Preference

        Upon our liquidation, whether voluntary or involuntary, each holder of depositary shares will be entitled to the fraction of the liquidation preference accorded each share of preferred stock represented by the depositary shares, as shown in the applicable prospectus supplement.

Conversion or Exchange of Preferred Stock

        The depositary shares will not themselves be convertible into or exchangeable for common stock, preferred stock or any of our other securities or property. Nevertheless, if so specified in the applicable prospectus supplement, the depositary receipts may be surrendered by holders to the applicable depositary with written instructions to it to instruct us to cause conversion of the preferred stock represented by the depositary shares. Similarly, if so specified in the applicable prospectus supplement, we may require holders of depositary shares to surrender all of their depositary receipts to the applicable depositary upon our requiring the conversion or exchange of the preferred stock represented by the depositary shares into a different class of our securities. We will agree that, upon receipt of the instruction and any amounts payable in connection with the conversion or exchange, we will cause the conversion or exchange using the same procedures as those provided for delivery of preferred stock to effect the conversion or exchange. If a holder of depositary shares is converting only a part of the

15

---

depositary shares, the depositary will issue the holder a new depositary receipt for any unconverted depositary shares.

Taxation

        A holder of depositary shares will be treated for U.S. federal income tax purposes as if it were a holder of the series of preferred stock represented by the depositary shares. Therefore, the holder of depositary shares will be required to take into account for U.S. federal income tax purposes income and deductions to which it would be entitled if it were a holder of the underlying series of preferred stock. In addition:

•

no gain or loss will be recognized for U.S. federal income tax purposes upon the withdrawal of preferred stock in exchange for depositary shares provided in the deposit agreement;



•

the tax basis of each share of preferred stock issued to a holder as exchanging owner of depositary shares will, upon exchange, be the same as the aggregate tax basis of the depositary shares exchanged for the preferred stock; and



•

if a holder held the depositary shares as a capital asset at the time of the exchange for preferred stock, the holding period for shares of the preferred stock will include the period during which the holder owned the depositary shares.

Amendment and Termination of a Deposit Agreement

        We and the applicable depositary are permitted to amend the form of the depositary receipt and the provisions of the deposit agreement. However, the holders of at least a majority of the applicable depositary shares then outstanding must approve any amendment that adds or increases fees or materially and adversely alters the rights of holders. Every holder of an outstanding depositary receipt at the time any amendment becomes effective, by continuing to hold the receipt, will be bound by the applicable deposit agreement, as amended.

        Any deposit agreement may be terminated by us upon not less than 30 days' prior written notice to the applicable depositary if a majority of each series of preferred stock affected by the termination consents to the termination. When that event occurs, the depositary will be required to deliver or make available to each holder of depositary shares, upon surrender of the depositary receipts held by the holder, the number of whole or fractional shares of preferred stock as are represented by the depositary shares evidenced by the depositary receipts, together with any other property held by the depositary with respect to the depositary shares. In addition, a deposit agreement will automatically terminate if:

•

all outstanding depositary shares have been redeemed;



•

there shall have been a final distribution in respect of the related preferred stock in connection with our liquidation and the distribution has been made to the holders of depositary receipts evidencing the depositary shares underlying the preferred stock; or



•

each of the shares of related preferred stock shall have been converted or exchanged into securities not represented by depositary shares.

Charges of a Depositary

        We will pay all transfer and other taxes and governmental charges arising solely from the existence of a deposit agreement. In addition, we will pay the fees and expenses of a depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. However, holders of depositary shares will pay any transfer taxes or other governmental charges and the fees and expenses of a depositary, including a fee for the withdrawal of shares of preferred stock upon surrender of depositary receipts, as are expressly provided in the deposit agreement to be for their accounts.

16

---

Resignation and Removal of Depositary

        A depositary may resign at any time by delivering to us notice of its election to do so. In addition, we may at any time remove a depositary. Any resignation or removal will take effect when we appoint a successor depositary and it accepts the appointment. We must appoint a successor depositary within 60 days after delivery of the notice of resignation or removal. A depositary must be a bank or trust company having its principal office in the United States that has a combined capital and surplus of at least $50 million.

Miscellaneous

        A depositary will be required to forward to holders of depositary shares any reports and communications that it receives from us with respect to the related preferred stock. Holders of depository shares will be able to inspect the transfer books of the depository and the list of holders of depositary shares upon reasonable notice.

        Neither we nor a depositary will be liable if either of us are prevented from, or delayed in performing, by law or any circumstances beyond our control, our obligations under a deposit agreement. Our obligations and those of the depositary under a deposit agreement will be limited to performing our duties in good faith and without gross negligence or willful misconduct. Neither we nor any depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary receipts, depositary shares or related preferred stock unless satisfactory indemnity is furnished. We and each depositary will be permitted to rely on written advice of counsel or accountants, on information provided by persons presenting preferred stock for deposit, by holders of depositary shares, or by other persons believed in good faith to be competent to give the information, and on documents believed in good faith to be genuine and signed by a proper party.

        If a depositary receives conflicting claims, requests or instructions from any holders of depositary shares, on the one hand, and us, on the other hand, the depositary shall be entitled to act on the claims, requests or instructions received from us.

DESCRIPTION OF OUR WARRANTS

        This section describes the general terms and provisions of our warrants to acquire our securities that we may issue from time to time. The applicable prospectus supplement will describe the specific terms of the warrants offered through that prospectus supplement.

        We may issue, together with any other securities being offered or separately, warrants entitling the holder to purchase from or sell to us, or to receive from us the cash value of the right to purchase or sell, our debt securities, preferred stock, depositary shares or common stock. We and a warrant agent will enter a warrant agreement pursuant to which the warrants will be issued. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. We will file a copy of the warrants and the warrant agreement with the SEC at or before the time of the offering of the applicable series of warrants. A holder of our warrants should refer to the provisions of the applicable warrant agreement and prospectus supplement for more specific information.

        In the case of each series of warrants, the applicable prospectus supplement will describe the terms of the warrants being offered thereby. These include the following, if applicable:

•

the offering price;



•

the number of warrants offered;



•

the securities underlying the warrants;

17

---

•

the exercise price, the amount of securities you will receive upon exercise, the procedure for exercise of the warrants and the circumstances, if any, that will cause the warrants to be automatically exercised;



•

the rights, if any, we have to redeem the warrants;



•

the date on which the warrants will expire;



•

U.S. federal income tax consequences;



•

the name of the warrant agent; and



•

any other terms of the warrants.

        Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in the applicable prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise and will not be entitled to payments made to holders of those securities.

        The warrant agreements may be amended or supplemented without the consent of the holders of the warrants to which it applies to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants. However, any amendment that materially and adversely alters the rights of the holders of warrants will not be effective unless the holders of at least a majority of the applicable warrants then outstanding approve the amendment. Every holder of an outstanding warrant at the time any amendment becomes effective, by continuing to hold the warrant, will be bound by the applicable warrant agreement as amended. The prospectus supplement applicable to a particular series of warrants may provide that certain provisions of the warrants, including the securities for which they may be exercisable, the exercise price and the expiration date, may not be altered without the consent of the holder of each warrant.

DESCRIPTION OF THE STOCK PURCHASE CONTRACTS AND THE STOCK PURCHASE UNITS

        We may issue contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of common stock at a future date or dates, which we refer to herein as "stock purchase contracts." The price per share of common stock and the number of shares of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. The stock purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and debt securities or debt obligations of third parties, including U.S. treasury securities, which secure the holders' obligations to purchase the common stock under the stock purchase contracts. We refer to these units herein as "stock purchase units." The stock purchase contracts may require holders to secure their obligations thereunder in a specified manner. The stock purchase contracts also may require us to make periodic payments to the holders of the stock purchase units or vice versa, and such payments may be unsecured or refunded on some basis.

        The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units. The description in the applicable prospectus supplement will not necessarily be complete, and reference will be made to the stock purchase contracts, and, if applicable, collateral or depositary arrangements, relating to the stock purchase contracts or stock purchase units. Material U.S. federal income tax considerations applicable to the stock purchase units and the stock purchase contracts will also be discussed in the applicable prospectus supplement.

DESCRIPTION OF CERTAIN PROVISIONS OF DELAWARE LAW AND
OUR CERTIFICATE OF INCORPORATION AND BYLAWS

        We are organized as a Delaware corporation. The following is a summary of our certificate of incorporation and bylaws and certain provisions of Delaware law, in each case as currently in effect. Because it is a summary, it does not contain all the information that may be important to you. If you want more information, you should read our entire certificate of incorporation and bylaws, copies of which we have previously filed with the SEC, see "Where You Can Find More Information," or refer to the provisions of Delaware law.

        Delaware law, our certificate of incorporation and our bylaws contain some provisions that could delay or make more difficult the acquisition of us by means of a tender offer, a proxy contest or otherwise. These provisions, as described below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us first to negotiate with us. We believe that the benefits of increased protection of our ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging such proposals because, among other things, negotiations with respect to such proposals could result in an improvement of their terms.

Section 203 of The Delaware General Corporation Law

        Section 203 of the Delaware General Corporation Law, or the DGCL, prohibits a defined set of transactions between a Delaware corporation, such as us, and an "interested stockholder." An interested stockholder is defined as a person who, together with any affiliates or associates of such person, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. This provision may prohibit business combinations between an interested stockholder and a corporation for a period of three years after the date the interested stockholder becomes an interested stockholder. The term "business combination" is broadly defined to include mergers, consolidations, sales or other dispositions of assets having a total value in excess of 10% of the consolidated assets of the corporation, and some other transactions that would increase the interested stockholder's proportionate share ownership in the corporation.

        This prohibition is effective unless:

•

either the business combination or the transaction that resulted in the interested stockholder becoming an interested stockholder is approved by our board of directors prior to the time the interested stockholder becomes an interested stockholder;



•

the interested stockholder owns at least 85% of our voting stock, other than stock held by directors who are also officers or by qualified employee stock plans, upon consummation of the transaction in which it becomes an interested stockholder; or



•

the business combination is approved by a majority of our board of directors and by the affirmative vote of 66²/3% of the outstanding voting stock that is not owned by the interested stockholder.

        In general, the prohibitions do not apply to business combinations with persons who were interested stockholders prior to the corporation becoming subject to Section 203.

19

---

Other Provisions of Our Certificate of Incorporation and Bylaws

        Our bylaws provide that a vacancy on the board of directors, including a vacancy created by an increase in the size of the board of directors by the directors, may be filled by a majority of the remaining directors, or by a sole remaining director, or by the stockholders, and each person so elected shall be a director to serve for the balance of the unexpired term of the directors. In addition, our bylaws provide that, in an uncontested election of directors, each director shall be elected by a majority of the votes cast by the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. In a contested election, the directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Under the DGCL, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at the election of directors.

        Our bylaws also provide that a majority of votes cast by the shares present in person or represented by proxy at any meeting of stockholders and entitled to vote thereat shall decide any question (other than the election of directors) brought before such meeting, except in any case where a larger vote is required by the DGCL, our certificate of incorporation, our bylaws or otherwise.

        Certain other provisions of our certificate of incorporation and bylaws could have the effect of preventing or delaying any change in control of us, including:

•

the advance notification procedures imposed on stockholders for stockholder nominations of candidates for the board of directors and for other stockholder business to be conducted at annual or special meetings;



•

the absence of authority for stockholders to call special stockholder meetings; and



•

the absence of authority for stockholder action by unanimous or partial written consent in lieu of an annual or special meeting.

        These provisions and statutory anti-takeover provisions, could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of us.

        Our certificate of incorporation includes provisions eliminating the personal liability of our directors to the fullest extent permitted by the DGCL, and our bylaws include provisions indemnifying our directors and officers to the fullest extent permitted by the DGCL. The limitation of liability and indemnification provisions in our certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though a derivative action, if successful, might otherwise benefit us and our stockholders. In addition, the value of investments in our securities may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

PLAN OF DISTRIBUTION

        We may sell the offered securities to one or more underwriters for public offering and sale by them. We may also sell the offered securities to investors directly or through agents. We will name any underwriter or agent involved in the offer and sale of the offered securities in the applicable prospectus supplement.

        The distribution of offered securities may be effected from time to time in one or more transactions at:

•

a fixed price or varying prices;

---

•

market prices prevailing at the time of sale;



•

prices related to the market prices; or



•

negotiated prices.

        Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters, dealers and agents may be entitled, under agreements with us, to indemnification against and contribution toward certain civil liabilities, including liabilities under the Securities Act, and to reimbursement by us for certain expenses.

        If an underwriter or underwriters are used in the offer or sale of securities, we will execute an underwriting agreement with the underwriters at the time of sale of the securities to the underwriters, and the names of the underwriters and the principal terms of our agreements with the underwriters will be provided in the applicable prospectus supplement.

        If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

        We may enter into derivative or other hedging transactions with financial institutions. These financial institutions may in turn engage in sales of our securities to hedge their position, deliver this prospectus in connection with some or all of those sales and use the shares covered by this prospectus to close out any short position created in connection with those sales. We may also sell shares of our securities short using this prospectus and deliver our securities covered by this prospectus to close out such short positions, or loan or pledge our securities to financial institutions that in turn may sell the shares of our securities using this prospectus. We may pledge or grant a security interest in some or all of our securities covered by this prospectus to support a derivative or hedging position or other obligation and, if we default in the performance of our obligations, the pledgees or secured parties may offer and sell our securities from time to time pursuant to this prospectus.

        Unless otherwise specified in the related prospectus supplement, each series of offered securities, other than shares of common stock, will be a new issue with no established trading market. Any shares of common stock sold pursuant to a prospectus supplement will be listed on the New York Stock Exchange, subject to official notice of issuance. We may elect to list any other series or class of offered securities on an exchange, but are not obligated to do so. Any underwriters to whom offered securities are sold by us for public offering and sale may make a market in those offered securities. Underwriters will not be obligated to make any market, however, and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of, or the trading markets for, any offered securities.

        Certain of the underwriters and their affiliates may engage in transactions with and perform services for us in the ordinary course of business for which they receive compensation.

        The specific terms and manner of sale of the offered securities will be shown or summarized in the applicable prospectus supplement.
