RISK FACTORS

Investing in our securities involves risk. You should carefully consider the risk factors incorporated by reference from our most recent Annual Report on Form 10-K, the information contained under the heading "Cautionary Note Regarding Forward-Looking Statements" in this prospectus or under any similar heading in any applicable prospectus supplement or in any document incorporated herein or therein by reference, any specific risk factors discussed under the caption "Risk Factors" in any applicable prospectus supplement or in any document incorporated herein or therein by reference and the other information contained in, or incorporated by reference in, this prospectus or any applicable prospectus supplement before making an investment decision. If any such risks occur, our business, financial condition or results of operations could be materially harmed, the market price of our securities could decline and you could lose all or part of your investment.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

We have made statements in this prospectus and the documents incorporated by reference herein that constitute "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995 and other federal securities laws. These forward-looking statements concern our operations, economic performance, financial condition, goals, beliefs, future growth strategies, investment objectives, plans and current expectations. The forward-looking statements are subject to various known and unknown risks, uncertainties and other factors. When we use words such as "believes," "expects," "anticipates," "estimates" or similar expressions, we are making forward-looking statements.

Although we believe that our forward-looking statements are based on reasonable assumptions, our expected results may not be achieved and actual results may differ materially from our expectations. Important factors that could cause actual results to differ from expectations include, among others, those set forth below. Please read carefully the information under "Risk Factors" beginning on page 1.

•: the cost to comply with current and future laws, regulations and customer demands relating to privacy issues;
•: the impact of litigation or disputes that may arise in connection with incidents in which we fail to protect our customers' information;

Table of Contents

•: changes in the price for our storage and information management services relative to the cost of providing such storage and information management services;
•: changes in customer preferences and demand for our storage and information management services;
•: the adoption of alternative technologies and shifts by our customers to storage of data through non-paper based technologies;
•: the cost or potential liabilities associated with real estate necessary for our business;
•: the performance of business partners upon whom we depend for technical assistance or management expertise outside the U.S.;
•: changes in the political and economic environments in the countries in which our international subsidiaries operate;
•: claims that our technology violates the intellectual property rights of a third party;
•: changes in the cost of our debt;
•: the impact of alternative, more attractive investments on dividends;
•: our ability or inability to complete acquisitions on satisfactory terms and to integrate acquired companies efficiently; and
•: other trends in competitive or economic conditions affecting our financial condition or results of operations not presently contemplated.

Other important factors that could cause actual results to differ materially from those in our forward-looking statements are described more fully in our most recently filed annual report on Form 10-K, including those described under the caption "Item 1A. Risk Factors," and other reports filed from time to time with the SEC and any prospectus supplement.

These cautionary statements should not be construed by you to be exhaustive and they are made only as of the date of this prospectus. You should not rely upon forward-looking statements except as statements of our present intentions and of our present expectations, which may or may not occur. You should read these cautionary statements as being applicable to all forward-looking statements wherever they appear. Except as required by law, we undertake no obligation to release publicly the result of any revision to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events or otherwise. Readers are also urged to review carefully and consider the various disclosures we have made or incorporated by reference in this prospectus, as well as our other periodic reports filed with the SEC.

RATIO OF EARNINGS TO FIXED CHARGES

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

	Year Ended December 31,										Three Months Ended March 31, 2013

	2008		2009		2010		2011		2012		Three Months Ended March 31, 2013
Ratio of Earnings to Fixed Charges		1.8x		2.2x		2.2x		2.2x		1.9x		1.7x

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

Table of Contents

costs, but do not include interest expense related to uncertain tax positions. We did not have any shares of preferred stock outstanding during any of the periods presented above, and therefore our ratios of earnings to combined fixed charges and preferred stock dividends are the same as the ratios of earnings to fixed charges presented above.

USE OF PROCEEDS

Unless otherwise described in a prospectus supplement, we intend to use the net proceeds from the sale of any securities covered by this prospectus for general business purposes, which may include acquisitions, investments, the repayment of indebtedness outstanding at a particular time and the payment of distributions to our stockholders. Until we apply the proceeds from a sale of the securities covered by this prospectus for their stated purposes, we may invest those proceeds in short-term investments, including repurchase agreements, some or all or which may not be investment grade.

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. If we issue debt securities, we will file any final indentures and/or supplemental indentures as exhibits to such registration statement. 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. If indicated in a prospectus supplement, the terms of such debt securities may differ from those described below.

The debt securities sold under this prospectus will be our direct obligations, 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, as amended. 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 our direct obligations and will rank equally and ratably in right of payment with our other indebtedness 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 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 the series, for issuances of additional securities of any such series.

Table of Contents

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 any such 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 debt 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;
•: 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 debt securities are denominated or payable in U.S. dollars, a foreign currency or units of two or more foreign currencies;
•: whether the amount of payments of principal of or premium, if any, or interest on the debt securities may be determined with reference to an index, formula or other method and the manner in which such amounts shall be determined;
•: the events of default and covenants of the debt 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 debt 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;

Table of Contents

•: 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 such debt securities 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 at 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 described 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 event of a change in control. You should review carefully the applicable prospectus supplement for information with respect to events of default and covenants applicable to the debt securities being offered.

Denominations, Interest, Registration and Transfer

Unless otherwise described in the applicable prospectus supplement, we will issue 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 or, at our option, 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 otherwise 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 the trustee will fix; or
•: in any other lawful manner, all 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 this role ourselves. The entity performing the role of maintaining the list of registered holders is called the "registrar." The registrar 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

Table of Contents

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 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 Securities Exchange Act of 1934, as amended, or the Exchange Act.

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

Events of Default and Related Matters

Events of Default. The term "event of default" for any series of debt securities means any of the following:

•: we do not pay the principal of, or any premium on, a debt security of that series on its due date;
•: we do not pay interest on a debt security of that series within 30 days after its due date;
•: we do not deposit any sinking fund payment for that series 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 an aggregate principal amount exceeding a dollar amount specified in the applicable prospectus supplement, which default results in the acceleration of the maturity of such 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 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;

Table of Contents

•: 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, if any, as defined in Regulation S-X 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 after 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.

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." Subject to certain conditions and if such 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.

Table of Contents

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;
•: 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 affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not materially adversely affect the holders of the debt securities. We require the same majority 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 in the first category described above under "—Changes Requiring Your Approval" without the consent of each holder of debt securities affected by the waiver.

Changes Not Requiring Approval. The third type of change does not require any vote by holders of debt securities. These changes are 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 the holders thereof are 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. The holders of debt securities are also not eligible to vote if they have been fully defeased, as described below under "—Defeasance

Table of Contents

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 any 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 satisfy all 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 U.S. federal income tax law must be changed or an Internal Revenue Service, or IRS, ruling must be issued permitting us to make the deposit described above without causing you to be taxed on the debt securities any differently than if we did not make the deposit and instead repaid the debt securities ourselves. Under current U.S. federal income 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. Under such circumstances, you could recognize gain or loss on the debt securities you were deemed to have returned to us.
•: We must deliver to the trustee a legal opinion confirming the U.S. federal income tax law change or IRS ruling 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 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 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. Conversely, the trust deposit would most likely be protected from any 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 will survive full defeasance:

•: your right to receive payments from the trust when payments are due;
•: our obligations relating to registration and transfer of debt securities and lost or mutilated certificates;
•: our obligations to maintain a payment office and to hold moneys for payment in trust;

Table of Contents

•: 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 U.S. current federal income 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 such 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
•: 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.

Conversion and Exchange Rights

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

Table of Contents

Subordination

We will describe 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 our other indebtedness. 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 with respect to such debt securities; and
•: provisions requiring holders of the debt securities being offered to remit payments to holders of senior indebtedness.

Global Securities

We may issue the debt securities of a series in whole or in part in the form of one or more registered global securities that we will deposit with a depositary or with a nominee for a depositary identified in the applicable prospectus supplement and registered in the name of such depositary or nominee. In such case, we will issue one or more registered global securities denominated in an amount equal to the aggregate principal amount of all of the debt securities of the series to be issued and represented by such registered global security or securities.

Unless and until it is exchanged in whole or in part for debt securities in definitive registered form, a registered global security may not be transferred except as a whole:

•: by the depositary for such registered global security to its nominee;
•: by a nominee of the depositary to the depositary or another nominee of the depositary; or
•: by the depositary or its nominee to a successor of the depositary or a nominee of the successor.

The prospectus supplement relating to a series of debt securities will describe the specific terms of the depositary arrangement with respect to any portion of such series represented by a registered global security. We currently anticipate that the following provisions will apply to all depositary arrangements for debt securities:

•: ownership of beneficial interests in a registered global security will be limited to persons that have accounts with the depositary for the registered global security, those persons being referred to as "participants," or persons that may hold interests through participants;
•: upon the issuance of a registered global security, the depositary for the registered global security will credit, on its book-entry registration and transfer system, the participants' accounts with the respective principal amounts of the debt securities represented by the registered global security beneficially owned by the participants;
•: any dealers, underwriters or agents participating in the distribution of the debt securities will designate the accounts to be credited; and
•: ownership of any beneficial interest in the registered global security will be shown on, and the transfer of any ownership interest will be effected only through, records maintained by the depositary for the registered global security (with respect to interests of participants) and on the records of participants (with respect to interests of persons holding through participants).

Table of Contents

The laws of some states may require that certain purchasers of securities take physical delivery of the securities in definitive form. These laws may limit the ability of those persons to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary for a registered global security, or its nominee, is the registered owner of the registered global security, the depositary or the nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the registered global security for all purposes under the applicable indenture. Except as set forth below, owners of beneficial interests in a registered global security:

•: will not be entitled to have the debt securities represented by a registered global security registered in their names;
•: will not receive or be entitled to receive physical delivery of the debt securities in the definitive form; and
•: will not be considered the owners or holders of the debt securities under the applicable indenture.

Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for the registered global security and, if the person is not a participant, on the procedures of a participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture.

We understand that under currently existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under an indenture, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take the action, and those participants would authorize beneficial owners owning through those participants to give or take the action or would otherwise act upon the instructions of beneficial owners holding through them.

We will make payments of principal of and premium, if any, and interest, if any, on debt securities represented by a registered global security registered in the name of a depositary or its nominee to the depositary or its nominee, as the case may be, as the registered owners of the registered global security. Neither we nor any trustee or any other agent of us or a trustee will be responsible or liable for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

We expect that the depositary for any debt securities represented by a registered global security, upon receipt of any payments of principal and premium, if any, and interest, if any, in respect of the registered global security, will immediately credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the registered global security as shown on the records of the depositary. We also expect that standing customer instructions and customary practices will govern payments by participants to owners of beneficial interests in the registered global security held through the participants, as is now the case with the securities held for the accounts of customers in bearer form or registered in "street name." We also expect that any of these payments will be the responsibility of the participants.

If the depositary for any debt securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, we will appoint an eligible successor depositary. If we fail to appoint an eligible successor depositary within 90 days, we will issue the debt securities in definitive form in exchange for the registered global security. In addition, we may at any time and in our sole discretion decide not to

Table of Contents

have any of the debt securities of a series represented by one or more registered global securities. In such event, we will issue debt securities of that series in a definitive form in exchange for all of the registered global securities representing the debt securities. The applicable trustee will register any debt securities issued in definitive form in exchange for a registered global security in such name or names as the depositary, based upon instructions from its participants, shall instruct such trustee.

We currently anticipate that certain registered 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 Cede & Co., as the nominee of DTC. DTC has advised us that 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 participants, or 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. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. 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. The rules applicable to DTC and its direct participants are on file with the SEC. The information in this paragraph 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 the accuracy thereof. In the event registered global securities are deposited with, or on behalf of, a depositary other than DTC, we will describe additional or differing terms of the depositary arrangements in the applicable prospectus supplement relating to that particular series of debt securities.

We may also issue bearer debt securities of a series in the form of one or more global securities, referred to as "bearer global securities." We currently anticipate that we will deposit these bearer global securities with a common depositary for Euroclear Bank S.A./N.V. and Clearstream Banking, société anonyme, or with a nominee for the depositary identified in the prospectus supplement relating to that series. The prospectus supplement relating to a series of debt securities represented by a bearer global security will describe the specific terms and procedures, including the specific terms of the depositary arrangement and any specific procedures for the issuance of debt securities in definitive form in exchange for a bearer global security, with respect to the portion of the series represented by a bearer global security.

Neither we nor any trustee assumes any responsibility for the performance by DTC or any other depositary 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.

Preferred Stock

The following is a summary of the general terms and provisions of the preferred stock that we may offer by this prospectus. 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 such 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 title and liquidation preference per share 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;

In general, no holders of our preferred stock will be entitled to preemptive rights to subscribe for any shares of any class or series of our capital stock, except as may be provided in a certificate of designations or any agreement between us and our stockholders. We have no current plans to grant preemptive rights through any agreement with our stockholders. 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

Table of Contents

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 Computershare Shareowner Services LLC as the registrar and transfer agent of any series of our preferred stock.

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.

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.

DESCRIPTION OF OUR DEPOSITARY SHARES

General

The following is a summary of the material provisions of any deposit agreement and of the depositary shares and depositary receipts representing depositary shares. 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 form of deposit agreement and depositary receipts which will be filed as exhibits to the registration statement of which this prospectus is a part prior to an offering of depositary shares. 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 our securities described in the applicable prospectus supplement. If indicated in a prospectus supplement, the terms of such securities may differ from those described below.

We may, at our option, elect to offer fractional interests in shares of preferred stock, rather than whole 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 show the name and address of the depositary. Subject to the terms of the applicable deposit agreement, each owner 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

The depositary will be required to distribute all cash distributions received in respect of the applicable preferred stock to the record holders of depositary receipts evidencing the related depositary shares in proportion to the number of depositary receipts owned by such holders on the relevant record date, which will be the same date as the record date fixed by us for the distribution paid on the applicable series of preferred stock.

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 receipts entitled thereto, 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 shares of 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 Shares of Preferred Stock

You may receive the number of whole shares of preferred stock and any money or other property represented by your depositary receipts after surrendering the depositary receipts at the corporate trust office of the depositary. Partial shares of preferred stock will not be issued. If the depositary receipts that you surrender exceed the number of depositary shares that represent the number of whole shares

Table of Contents

of preferred stock you wish to withdraw, then the depositary will deliver to you at the same time a new depositary receipt evidencing the excess number of depositary shares. Once you have withdrawn your shares of preferred stock, you 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.

Redemption of Depositary Shares

If we redeem a series of the preferred stock underlying the depositary shares, the depositary will redeem those shares from the proceeds received by it. 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 receipts evidencing 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 the applicable preferred stock 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 receipts. Each record holder of depositary receipts 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. If you do not instruct the depositary how to vote your shares, the depositary will abstain from voting those shares. The depositary will not be responsible for any failure to carry out an instruction to vote or for the effect of any such vote made so long as the action or inaction of the depositary is in good faith and is not the result of the depositary's gross negligence or willful misconduct.

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 described in the applicable prospectus supplement.

Conversion or Exchange of Shares 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 or exchange of the preferred stock represented by the depositary shares. Similarly, if so specified in the applicable prospectus supplement, we may require you to surrender all of your depositary receipts to the applicable depositary upon our requiring the conversion or exchange of the preferred stock represented by the

Table of Contents

depositary shares. 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 you are converting or exchanging only a part of the depositary shares, the depositary will issue you a new depositary receipt for any unconverted or unexchanged depositary shares.

Taxation

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

•: no gain or loss will be recognized for U.S. federal income tax purposes upon the withdrawal of shares of preferred stock in exchange for depositary shares provided in the deposit agreement;
•: the tax basis of each share of preferred stock issued to you as exchanging owner of depositary shares will, upon exchange, be the same as the aggregate tax basis of the depositary shares exchanged for the shares of preferred stock; and
•: if you 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 you owned the depositary shares.

Amendment and Termination of a Deposit Agreement

We and the applicable depositary are permitted to amend the provisions of the depositary receipts and 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 a deposit agreement is terminated, the depositary will be required to deliver or make available to each holder of depositary receipts, 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 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

Table of Contents

with the initial deposit of the shares of preferred stock and any redemption of the shares of preferred stock. However, holders of depositary receipts will pay any transfer taxes or other governmental charges and the fees and expenses of the depositary, including any duties the holders request to be performed that are outside of those expressly provided for in the applicable deposit agreement.

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

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

Neither we nor the depositary will be liable if the depositary is prevented from or delayed in performing its obligations under a deposit agreement by law or any circumstances beyond its control. Our obligations and those of the depositary under a deposit agreement will be limited to performing duties in good faith and without gross negligence or willful misconduct. Neither we nor the 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 the 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 receipts 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 the depositary receives conflicting claims, requests or instructions from any holders of depositary receipts, 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

The following is a summary of the material terms of our warrants and the warrant agreement. 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 warrants and the warrant agreement which will be filed as exhibits to the registration statement of which this prospectus is a part. 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 our securities described in the applicable prospectus supplement. If indicated in a prospectus supplement, the terms of such securities may differ from those described below.

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, debt securities, shares of preferred stock, depositary shares or shares of 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.

Table of Contents

We will file a copy of the forms of warrants and the warrant agreement with the SEC at or before the time of the offering of the applicable series of warrants.

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 currencies in which such warrants are being offered;
•: the number of warrants offered;
•: the securities underlying the warrants;
•: the exercise price, the procedures 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;
•: the name of the warrant agent; and
•: any other terms of the warrants.

If material, we will discuss in the applicable prospectus supplement U.S. federal income tax considerations applicable to the warrants offered by such prospectus supplement.

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.

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. If material, we will discuss in the applicable prospectus supplement U.S. federal income tax considerations applicable to the stock purchase units and the stock purchase contracts offered by such 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

We are subject to Section 203 of the Delaware General Corporation Law, or the DGCL. Subject to specific exceptions, Section 203 prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the time the person became an interested stockholder, unless:

•: the business combination, or the transaction in which the stockholder became an interested stockholder, is approved by our board of directors prior to the time the interested stockholder attained that status;
•: upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
•: at or after the time a person became an interested stockholder, the business combination is approved by our board of directors and authorized at an annual or special meeting of stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

"Business combinations" include mergers, asset sales and other transactions resulting in a financial benefit to the interested stockholder. Subject to various exceptions, in general an "interested stockholder" is a person that, together with his or her affiliates and associates, owns, or within three years did own, 15% or more of our outstanding voting stock.

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

Table of Contents

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 securities under this prospectus from time to time. We may sell the securities in one or more of the following ways from time to time:

•: to or through one or more underwriters or dealers;
•: in short or long transactions;
•: directly to investors;
•: through agents; or
•: through a combination of any of these methods of sale.

If we use underwriters or dealers in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including:

•: in privately negotiated transactions;
•: in one or more transactions at a fixed price or prices, which may be changed from time to time;

Table of Contents

•: in "at the market offerings," within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;
•: at prices related to those prevailing market prices; or
•: at negotiated prices.

We, and our underwriters, dealers or agents, reserve the right to accept or reject all or part of any proposed purchase of the securities. We will set forth in a prospectus supplement and pricing supplement, if any, the terms and offering of securities, including:

•: the names of any underwriters, dealers or agents;
•: any agency fees or underwriting discounts or commissions and other items constituting agents' or underwriters' compensation;
•: any discounts or concessions allowed or reallowed or paid to dealers;
•: details regarding over-allotment options under which underwriters may purchase additional securities from us, if any;
•: the purchase price of the securities being offered and the proceeds we will receive from the sale;
•: the public offering price; and
•: the securities exchanges on which such securities may be listed, if any.

We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions from time to time. If the applicable prospectus supplement or pricing supplement, if any, indicates, in connection with those derivative transactions, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus, the applicable prospectus supplement and pricing supplement, if any, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivative transactions to close out any related open borrowings of securities. The third parties (or affiliates of such third parties) in such sale transactions will be underwriters and will be identified in an applicable prospectus supplement (or a post-effective amendment).

We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus, an applicable prospectus supplement and an applicable pricing supplement, if any. Such financial institution or third party may transfer its economic short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus.

Underwriters, Agents and Dealers. If underwriters are used in the sale of our securities, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions described above. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by underwriters. Generally, the underwriters' obligations to purchase the securities will be subject to conditions precedent and the underwriters will be obligated to purchase all of the securities if they purchase any of the securities. We may use underwriters with which we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase our securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the

Table of Contents

future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Underwriters, dealers and agents may contract for or otherwise be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments made by the underwriters, dealers or agents, under agreements between us and the underwriters, dealers and agents.

We may grant underwriters who participate in the distribution of our securities an option to purchase additional securities to cover over-allotments, if any, in connection with the distribution.

Underwriters, dealers or agents may receive compensation in the form of discounts, concessions or commissions from us or our purchasers, as their agents in connection with the sale of our securities. These underwriters, dealers or agents may be considered to be underwriters under the Securities Act. As a result, discounts, commissions or profits on resale received by the underwriters, dealers or agents may be treated as underwriting discounts and commissions. The prospectus supplement will identify any such underwriter, dealer or agent and describe any compensation received by them from us. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

Any underwriter may engage in over-allotment transactions, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short-covering transactions involve purchases of our securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. We make no representation or prediction as to the direction or magnitude of any effect these transactions may have on the price of our securities. For a description of these activities, see the information under the heading "Underwriting" in the applicable prospectus supplement.

Underwriters, broker-dealers or agents who may become involved in the sale of our securities may engage in transactions with and perform other services for us for which they receive compensation.

Direct Sales. We may also sell securities directly to one or more purchasers without using underwriters or agents. In this case, no agents, underwriters or dealers would be involved. We may sell securities upon the exercise of rights that we may issue to holders of our securities. We may also sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities.

Trading Market and Listing of Securities. We will make applications to list any shares of common stock sold pursuant to a supplement to this prospectus on the NYSE. We have not determined whether we will list any of the other securities we may offer on any national exchange or over-the-counter market, and any such listing will be disclosed in the applicable prospectus supplement. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

Set forth below is an estimate (except in the case of the registration fee) of the amount of fees and expenses to be incurred in connection with the issuance and distribution of the offered securities registered hereby, other than underwriting discounts and commission, if any, incurred in connection with the sale of the offered securities. All such amounts will be borne by Iron Mountain Incorporated, or Iron Mountain or the Company.


Registration Fee Under Securities Act of 1933	$		*
Legal Fees and Expenses	$	75,000
Accounting Fees and Expenses	$	20,000
Miscellaneous Fees and Expenses	$	5,000

Total:	$	100,000

*: In accordance with Rule 456(b) and 457(r) under the Securities Act of 1933, as amended, we are deferring payment of the registration fee for the securities offered hereby.

These expenses represent an estimate of the expenses we expect to incur in connection with the preparation and filing of this registration statement. Other expenses in connection with the issuance and distribution of securities to be offered hereunder are contingent on the number of offerings and cannot reasonably be estimated at this time.

Item 15. Indemnification of Directors and Officers

We are a Delaware corporation. Section 102 of the Delaware General Corporation Law, or the DGCL, permits a corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of a director to a corporation or its stockholders for monetary damages for certain breaches of the director's fiduciary duty, except (1) for any breach of the director's duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) the payment of unlawful dividends or unlawful stock repurchases or redemptions or (4) transactions from which the director received an improper personal benefit. Our certificate of incorporation eliminates the liability of directors to the fullest extent permissible under Delaware law.

Section 145 of the DGCL, or Section 145, authorizes a corporation to indemnify its directors, officers, employees and agents against certain liabilities (including attorneys' fees, judgments, fines and expenses) they may incur in connection with specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation, or a derivative action), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. Section 145 also provides that such persons have a right to indemnification against expenses where they have been successful on the merits or otherwise in defense of such actions. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys' fees) incurred in connection with defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. Section 145 empowers the corporation to purchase and maintain insurance on behalf of any directors, officers, employees and agents, against any liability asserted against such person and

II-1

Table of Contents

incurred by such person in any such capacity, whether or not the corporation would have the power to indemnify such person against such liability under Section 145.

Section 145 provides that the indemnification provided thereby is not exclusive of any other indemnification rights that may exist under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise.

Article 12 of the Company's bylaws provides indemnification to directors and officers for all actions taken by them and for all failures to take action to the fullest extent permitted by Delaware law against all expense, liability and loss reasonably incurred or suffered by them in connection with any threatened, pending or completed action, suit or proceeding (including, without limitation, an action, suit or proceeding by or in the right of the Company), whether civil, criminal, administrative or investigative. Article 12 also permits the Company, by action of its board of directors, to indemnify employees and other agents of the Company to the same extent as directors and officers. Amendments, repeals or modifications of Article 12 can only be prospective and no such change may reduce the limitations of director's liability or limit indemnification or advancement of expenses unless adopted by the unanimous vote of all of the directors then serving or the affirmative vote of the holders of a majority of the outstanding shares of stock of the Company entitled to vote in elections of directors. Article 12 further permits the Company to maintain insurance, at its expense, for the benefit of any person on behalf of whom insurance is permitted to be purchased by Delaware law against any such expenses, liability or loss.

Reference is made to our bylaws, filed as Exhibit 3.1 to our Current Report on Form 8-K filed with the Securities and Exchange Commission, or the SEC, on March 5, 2010. Reference is also made to our Amended and Restated Certificate of Incorporation, as amended, filed as Exhibit 3.1 to our Annual Report on Form 10-K for the year ended December 31, 2006.

As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initialbona fide offering thereof.Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrants undertake that in a primary offering of securities of the undersigned registrants pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrants will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i): Any preliminary prospectus or prospectus of the undersigned registrants relating to the offering required to be filed pursuant to Rule 424;
(ii): Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrants or used or referred to by the undersigned registrants;

(iii): The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrants or their securities provided by or on behalf of the undersigned registrants; and
(iv): Any other communication that is an offer in the offering made by the undersigned registrants to the purchaser.

(b) The undersigned registrants hereby undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of Iron Mountain's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fide offering thereof.

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

(d) Each of the undersigned registrants hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act of 1939, or the Act, in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.
